[Detailed explanation of the device]

<Field of the Invention> This device is about to the device which indicates the delivery length of a fishing line by detection correctly. <Prior art and a problem> The casting or fishing line which throws in a fishhook is hung down perpendicularly, and it is requested that the delivery length of a fishing line is got to know correctly in any cases, such as the method of maintaining at underwater request depth, A sign special to a fishing line outside the method of presentation which changes color for every fixed length of a fishing line for this object is formed, and the device which detects and Demonstrator the move direction and the number of passage of this sign, and displays the delivery length of a fishing line is also proposed. The magnetic sign which has N and the S pole in a fishing line as the example of - is really formed for every length, the move direction of U::1"1 fishing line is judged by the polarity, and it is Transfer (: and "-Movement are computed and the device which displays delivery length is also proposed.) by the number of passage of a sign. However, when it becomes a cost overrun to form such a special sign in a fishing line and this is rolled round to a reel, there is a fault which causes bearing to the delivery of a fishing line and rolling up for adsorption by the polarity of a sign, and a rebounding operation. <The solving means of a problem> This device makes the sign which is a thing aiming at solving the above faults, and it gives to a fishing line the thing of the character in which the transmissivity of light differs from reflectance, and is a light emitting element, It is by what was resigned so that two photo acceptance units arranged before and after that might detect the direction of movement and the number of sign passage of a fishing line and the delivery length of a fishing line might be indicated by Closing. <Example> Usually, as shown in Drawing 1, fishing line a is attached near the hand of Fishing rod, or is rolled round by - Le C, and it lets it out through guide d which Fishing rod fixed, and rolling up is performed. Fishing line a which formed the sign with which this device used change of the transmissivity of light, or reflectance for every constant interval Sign detecting device d which stored in the camera two photo acceptance units which receive the light emitting element which @ Shoots and carries out this fishing line a and its penetration light, or anti-L2 light reflection The number of passage of a sign and the move direction of a fishing line are judged with the sign passage signal from a photo acceptance unit, and it comprises computer e and display f which calculate the delivery length of a fishing line. Now, as an example of -, as shown in Drawing 2 A, what gave black sign 1 10 cm of fixed length, for example, every, is used for fishing line a like a color-free gut and translucent plastic fiber thread. Sign detecting device d is what allocated two photo acceptance units 5.6 in the side opposite to the passage which counters light emitting element 4 and the light emitting element at the 1 side of fishing line path 3 provided in camera 2 shown in Drawing 3 A, Although Fishing rod of To fixes this to reel C, delivery or rolling up is performed through this passage 5, the light fishing line a was irradiated from light emitting element 4 passes a translucent fishing line and fishing line a is received by photo acceptance unit 5.6, Since penetration light will be intercepted if it passes in a black sign", passage of a sign is detectable with photo acceptance unit 5.6. While the sign passage detection signal of this photo acceptance unit 5.6 is amplified by amplifier 7.7 so that it may illustrate to Drawing 4, and being sent to computer e and calculating the number which passed sign " and photo acceptance unit 5.6 of the fishing line by the computer, It distinguishes which photo acceptance unit or sign 1 was previously detected among photo acceptance units 5.6 of one b2 signs, When photo acceptance unit 5 of the direction near a reel is the point and photo acceptance unit 6 of Samurai and the distant one is early - It closes, when sign 1 passes both photo acceptance units 5.6, it Lecture as one sign passage, and the 10c+++ twice of the Mike value are displayed with display f. The above-mentioned pair 1 - Thae and display f are attached to the hand part of Fishing rod, or it may enable it to carry them as another object. Fishing line a can perform 3 coloring from which transmissivity or reflectance differs for every fixed length, as shown in Drawing 2 B outside the above-mentioned example, and it can also detect the point that the colors differ, as sign 1'. As it is shown in Drawing 3 B whether the above-mentioned example of sign detecting device d is what detects a sign by change "--2 of penetration light, photo acceptance unit 5.6 can be arranged on light emitting element 4 and its both sides at the 1 side of fishing line path 3 of a camera, the catoptric light from a fishing line can be received with photo acceptance unit 5.6, and a sign can also be detected. <The effect of a device> In this device, since a sign uses the permeability of light, or reflexibility, a user can attach a sign to a non-sign fishing line easily, moreover -- since the commercial fishing line classified by color can also be used as it is and does not need the sign by special working machinery, while acquisition of a fishing line is easy and economical -- the delivery from a reel, and rolling up - of a magnetic body sign, -, and -delta -- there is no fault [ like ]. After a sign stops [ the device which detects a sign with a single element ] in the position of a detection element, when a fishing line moves to an opposite direction, While the number Preparation of passage of the move direction of a fishing line and a sign has a possibility of producing misconception, since a direction judging and the number of sign passage are distinguished with two photo acceptance units, by this device, it is effective in the ability to perform an exact display.
