Apparatus and method for registering commodity information

CROSS-REFERENCE TO RELATED APPLICATION

This application is based upon and claims the benefit of priority from Japanese Patent Application No. <patcit id="pcit0001" dnum="JP2018076515A"><text>2018-076515, filed on April 12, 2018</text></patcit>, the entire contents of which are incorporated herein by reference.

FIELD

Embodiments described herein relate generally to an apparatus and a method for registering commodity information.

BACKGROUND

In a retail store, such as a supermarket or a convenience store, a self-service checkout apparatus, such as disclosed in Japanese Unexamined Patent Application Publication No. <patcit id="pcit0002" dnum="JP2017174474A"><text>2017-174474</text></patcit>, permitting a customer to perform some or all of the operations relating to commodity registration can be installed.

In such a self-service checkout apparatus, a customer presses a button or key associated with the commodity being purchased or holds the commodity over a scanner to register commodity information for the sales transaction.

In such a self-service checkout apparatus, a commodity can be registered by reading a code symbol (for example, a barcode) on the commodity with a scanner. For any commodity to which a code symbol has not been attached, the commodity can be registered by pressing a button associated with the identity of the commodity. In order to improve checkout operations, the self-service checkout apparatus issues a notification with light and/or sound when a code symbol is scanned by the scanner. When a commodity selection button is pressed, the self-service checkout apparatus also issues a notification with sound.

However, this notification sound or light does not necessarily indicate that the commodity information is correctly registered. For example, there is a possibility that a customer appears to registers one type of commodity fraudulently by scanning a code symbol attached to a cheaper commodity rather than the appropriate code symbol. There is also a possibility that the customer registers a commodity unfairly by pressing a commodity choice button associated with a cheaper commodity.

(Description of Overall Configuration of Self-service POS Terminal)

<figref idref="f0001">Fig. 1</figref> is a perspective view illustrating an external appearance of a self-service POS terminal 1 according to an embodiment. A main body 22 of the self-service POS terminal 1 includes a display 24, a scanner 25 and a hand-held scanner 26. On the surface of the display 24, a touch panel 23 is arranged.

The display 24 is, for example, a liquid crystal display. The display 24 can display a guide screen or the like for informing a customer about the operation methods of the self-service POS terminal 1. The display 24 displays a selection registration screen S1 (refer to <figref idref="f0004">Fig. 4</figref>) for registering a commodity by the selection of a commodity choice button associated with the commodity in advance. The display 24 displays a reading registration screen S2 (refer to <figref idref="f0005">Fig. 5</figref>) which displays the commodity information registered by reading a code symbol attached to the commodity by the scanner 25 or the hand-held scanner 26. The display 24 displays a total amount of commodities, a deposit amount, a change amount, etc., and displays a checkout screen or the like for allowing the customer to select a payment method.

The scanner 25 or the hand-held scanner 26 reads a code symbol such as a barcode or a two-dimensional code attached to the commodity. The scanner 25 includes, for example, an optical image capturing element such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). The scanner 25 images of items placed in an image capturing region in front of a reading window. The customer holds the code symbol attached to the commodity to the reading window of the scanner 25 and the scanner 25 reads the code symbol. It may be difficult to hold a code symbol attached to some commodities such as a large cardboard box or a long commodity over the reading window of scanner 25. In such a case, the customer uses the hand-held scanner 26 to read the code symbol. In the code symbol, coded information such as a JAN (Japanese Article Number) code or CODE 128 which can uniquely specify a commodity is encoded. The scanner 25 or the hand-held scanner 26 may further have a function of identifying a commodity by generic object recognition (object recognition).

In the vicinity of the reading window of the scanner 25, a light emitting section 16 is provided. For example, a LED (Light Emitting Diode) is built in the light emitting section 16, and the light emitting section 16 lights up over a predetermined period of time when the scanner 25 reads the code symbol attached to a commodity or when the code reading result is registered. The light emitting section 16 lights up over a predetermined period of time when a customer registers a commodity using the selection registration screen described above. The light emitting section 16 is not limited to being installed in the vicinity of the reading window of the scanner 25. For example, instead of the light emitting section 16, a light emitting section 17 having the same function as the light emitting section 16 may be installed above the display 24. The light emitting section 16 and the light emitting section 17 are each an example of an illumination module.

Since the light emitting section 17 is installed at a higher position than the light emitting section 16, a store clerk, who is monitoring a state of the self-service POS terminal 1, can also be made aware of the illumination state as well the customer who operates the self-service POS terminal 1. In some examples, the light emitting section 16 may also or instead be installed in an attendant terminal that monitors operation states of a plurality of self-service POS terminals 1 in addition to the vicinity of the reading window of the scanner 25. In other words, a store clerk monitoring the operation state of the self-service POS terminal 1 may monitor a light emission state of the light emitting section 16.

On the right side of the main body 22, a commodity placement table 27 on which a customer generally places an unsettled/unregistered commodity items is provided. The unsettled/unregistered commodity items may be in a shopping basket when placed on the commodity placement table 27. On the left side of the main body 22, a commodity placement table 28 on which the customer is to place a settled/registered commodity item is provided. Above the commodity placement table 28, a bag hook 8 for hanging a bag in which settled/registered commodity items may be placed, and a temporary placement table 9 on which the customer may temporarily place settled/registered commodity items before bagging or the like are provided. The commodity placement table 27 has a weighing machine (scale) 34 therein, and the commodity placement table 28 has a weighing machine (scale) 35 therein. The self-service POS terminal 1 is configured to output an error message when the total weight of the commodities before commodity registration and after the commodity registration are different by some predetermined amount or percentage.

The main body 22 is provided with a card reader 30 for reading a rewards points card or a credit card of the customer. For settlement, the card reader 30 reads a point card or a credit card inserted in a card insertion slot 10. The main body 22 is provided with a receipt printer 31 for printing a receipt. The receipt printed by the receipt printer 31 is issued from a receipt issuing port 11.

In the main body 22, a deposit and dispensing device 32 which calculates an amount of bills and coins deposited by the customer at the time of settlement and dispenses bills or coins as a change as necessary is provided. The customer deposits bills for settlement and receives bills as the change via a bill deposit and dispensing port 12. The customer inserts coins via a coin insertion slot 13 and receives coins as the change from a coin outlet 14.

Furthermore, a pole is provided on an upper surface of the main body 22. At the upper end of the pole, a warning light 15 that lights up when there is an abnormality in an operation performed at the self-service POS terminal 1 or when a store clerk is requested is provided.

Pressing the subtotal button B1 signals the self-service POS terminal 1 that the commodity registration is completed(refer to <figref idref="f0005">Fig. 5</figref>).

(Registration Processing)

The self-service POS terminal 1 concurrently performs registration processing for each registering of a commodity and a notification processing for signaling that the commodity has been registered each time a commodity is registered. <figref idref="f0007">Fig. 7</figref> is a flowchart depicting flows of the registration processing and the notification processing performed by the self-service POS terminal 1 according to an embodiment.

The commodity information registration section 52 of the self-service POS terminal 1 detects, for example, that a commodity registration option has been selected from a main menu screen displayed on the display 24, and starts the commodity registration processing.

First, the commodity information reading section 61 controls the scanner 25 to perform image input (image capturing) (Act S10). If the hand-held scanner 26 is operated, the hand-held scanner 26 performs the image input instead of the scanner 25, but in the following description, only a case in which the scanner 25 is used is described.

The commodity information reading section 61 processes a captured image from scanner 25 to detect a barcode. Then, the commodity information reading section 61 determines whether the barcode has been detected (Act S12). If it is determined that the barcode is detected (Yes in Act S12), the flow proceeds to the processing in Act S14. On the other hand, if it is determined that the barcode is not detected (No in Act S12), the flow proceeds to the processing in Act S24.

If Yes is determined in Act S12, the commodity information reading section 61 reads the code information such as the JAN code encoded in the barcode in Act S14.

Next, the commodity information registration section 52 registers the commodity for which the code information has been read (Act S16).

The notification instruction section 53 outputs a notification instruction A to the notification section 54 (Act S18). The notification instruction A is used to notify that a commodity registration has been performed by the reading (scanning) of code information. For example, the notification instruction A enables or causes the light emitting section 16 (or light emitting section 17) to emit blue light.

The notification instruction section 53 determines whether a predetermined period of time has elapsed since the notification instruction A was output (Act S20). If it is determined that the predetermined period of time elapses (Yes in Act S20), the flow proceeds to the processing in Act S22. On the other hand, if it is determined that the predetermined period of time has not elapsed (No in Act S20), the determination in Act S20 is repeatedly executed. The predetermined period of time is set to 0.5 seconds, for example.

If Yes is determined in Act S20, the notification instruction section 53 issues, in Act S22, an instruction to cancel the notification instruction A to the notification section 54.

Next, the commodity designation section 51 determines whether a button PB has been pressed in the selection registration screen S1 (Act S24). If No is determined in Act S12, the processing in Act S24 is also executed.

Although not specifically depicted in the flowchart in <figref idref="f0007">Fig. 7</figref>, the selection registration screen S1 is displayed when the commodity information registration section 52 detects that the commodity registration option permitting user selections of preset commodity choices was selected from the main menu screen or the like previously displayed on the display 24 before the start of registration processing.

In Act S24, if it is determined that a button PB is pressed (Yes in Act S24), the flow proceeds to the processing in Act S26. On the other hand, if it is determined that the button PB is not pressed (No in Act S24), the flow proceeds to the processing in Act S34.

If it is determined Yes in Act S24, in Act S26, the commodity information registration section 52 registers the commodity associated with the pressed button PB (Act S26).

The notification instruction section 53 outputs a notification instruction B to the notification section 54 (Act S28). The notification instruction B is used to signal that a commodity registration has been performed by the selecting of a button PB. For example, the notification instruction B enables or causes the light emitting section 16 (or light emitting section 17) to emit green light. In other words, the notification instruction A and the notification instruction B provide notifications/signals in different formats (e.g., different lamp colors or otherwise).

The notification instruction section 53 determines whether a predetermined period of time has elapsed since the notification instruction B was output (Act S30). If it is determined that the predetermined period of time elapses (Yes in Act S30), the flow proceeds to the processing in Act S32. On the other hand, if it is determined that the predetermined period of time has not elapsed (No in Act S30), the determination in Act S30 is repeatedly executed. The predetermined period of time is set to 0.5 seconds, for example.

If Yes is determined in Act S30, the notification instruction section 53 issues, in Act S32, an instruction to cancel the notification instruction B to the notification section 54.

Next, the commodity information registration section 52 determines whether the subtotal button B1 has been pressed (Act S34). If No is determined in Act S24, the processing in Act S34 is also executed.

In Act S34, if it is determined that the subtotal button B1 has been pressed (Yes in Act S34), the flow proceeds to the processing in Act S36. On the other hand, if it is determined that the subtotal button B1 has not been pressed (No in Act S34, the flow returns to the processing in Act S10.

If Yes is determined in Act S34, the commodity information reading section 61 terminates the registration processing in Act S36. Although not specifically shown in <figref idref="f0007">Fig. 7</figref>, the self-service POS terminal 1 next instructs the customer to perform settlement processing for settling the registered items in the transaction.

In <figref idref="f0007">Fig. 7</figref>, the commodity registration code symbol scanning is performed first, and then the commodity registration by selections of a button PB is performed. However, the order thereof may be reversed in other examples. Likewise, the commodity registration by scanning and the commodity registration button PB selecting may be repeated any number of times in a random order including multiple switches back and forth between the different commodity registration methods.

(Description of Flow of Notification Processing)

Next, a flow of the notification processing is described with reference to <figref idref="f0007">Fig. 7</figref> as well. If the commodity information registration section 52 of the self-service POS terminal 1 starts the commodity registration processing, the notification section 54 also starts the notification processing.

The notification section 54 determines whether the notification instruction A has been issued (Act S40) . If it is determined that the notification instruction A has been issued (Yes in Act S40), the flow proceeds to the processing in Act S42. On the other hand, if it is determined that the notification instruction A has not been issued (No in Act S40), the flow proceeds to the processing in Act S48.

If Yes is determined in Act S40, the notification section 54 turns on the light emitting section 16 (or light emitting section 17) in Act S42.

Subsequently, the notification section 54 determines whether the notification cancellation instruction has been issued (Act S44). If it is determined that the notification cancellation instruction has been issued (Yes in Act S44), the flow proceeds to the processing in Act S46. On the other hand, if it is determined that the notification cancellation instruction has not been issued (No in Act S44), the processing in Act S44 is repeated.

If Yes is determined in Act S44, the notification section 54 turns off the light emitting section 16 (or light emitting section 17) in Act S46.

The notification section 54 determines whether the notification instruction B has been issued (Act S48). If it is determined that the notification instruction B has been issued (Yes in Act S48), the flow proceeds to the processing in Act S50. On the other hand, if it is determined that the notification instruction B has not been issued (No in Act S48), the flow returns to the processing in Act S40.

If Yes is determined in Act S48, the notification section 54 turns on the light emitting section 16 (or 17) in Act S50.

Subsequently, the notification section 54 determines whether the notification cancellation instruction has been issued (Act S52). If it is determined that the notification cancellation instruction has been issued (Yes in Act S52), the flow proceeds to the processing in Act S54. On the other hand, if it is determined that the notification cancellation instruction has not been issued (No in Act S52), the processing in Act S52 is repeated.

If it is determined as Yes in Act S52, the notification section 54 turns off the light emitting section 16 (or light emitting section 17) in the Act S54.

Next, the notification section 54 determines whether the registration processing has terminated (Act S56). If it is determined that the registration processing has been terminated (Yes in Act S56), the flow proceeds to the processing in Act S58. On the other hand, if it is determined that the registration process is not terminated (No in Act S56), the flow returns to the processing in Act S40.

If Yes is determined in Act S56, the notification section 54 terminates the notification processing in Act S58.

As described above, in the self-service POS terminal 1 of an embodiment), when the commodity information registration section 52 registers the commodity information of a commodity designated by the commodity designation section 51 or a commodity read by the commodity information reading section 61, the notification instruction section 53 instructs the notification section 54 to signal that the commodity information has been registered. Therefore, since the customer knows that notification is performed when the commodity selected by himself/herself is registered, it is possible to reduce the likelihood of fraudulent commodity registrations performed through unfair operation.

In the self-service POS terminal 1, when selection of a button PB associated with a commodity is detected, the commodity designation section 51 designates the commodity associated with the button PB. Alternatively, the commodity information reading section 61 designates a commodity when a code symbol including the code information for uniquely specifying the commodity is read. The commodity information registration section 52 registers the commodity information of the designated commodity. Therefore, the notification instruction section 53 can signal that the commodity information has been registered regardless of the input method used for registering the commodity.

In the self-service POS terminal 1, the notification instruction section 53 instructs the notification section 54) to perform notification in different notification forms depending on whether the commodity designation section 51 designates the commodity by detecting the operation on a button PB or the commodity information reading section 61 designates the commodity by scanning a code symbol. Therefore, since notifications are performed by different methods when different registration input methods are used, it is difficult for the customer to perform an unfair operation considering that all registration operations performed by himself/herself are monitored by output of notifications.

In the self-service POS terminal 1, the notification section 54 includes at least one illumination module, such as light emitting section 16 or light emitting section 17, which is attached to the commodity information registration section 52 or the commodity information reading section 61. An illumination module may also be installed in an attendant terminal separated from the self-service POS terminal 1 and used to monitor the operation state of the self-service POS terminal 1. Therefore, a clerk can monitor the commodity registration process at the self-service POS terminal 1, for example, to detect whether a customer is puzzled about the registration operation.

In the self-service POS terminal 1, the notification instruction section 53 instructs the notification section 54 to make a notification for a predetermined period of time. Therefore, the customer can reliably recognize that the commodity has been registered.
