[Problems to be Solved by the Invention]

In this way, when the tape cartridge is held in the cartridge mounting part by the conventional holding claw, if the spring force of the holding claw is set small, the tape cartridge will be lifted when the printing tape is fed out, and the tape will be skewed. There was a problem that jamming occurred. In particular, in the case of the resin holding claw integrally formed with the mounting case, the holding claw itself may be worn out and the spring force may be reduced if the holding claw is used for a long time. On the contrary, if the spring force of the holding claw is set to be large, a large force is required to attach / detach the tape cartridge, which causes a problem that the attachment / detachment of the tape cartridge becomes complicated.

【0004】

An object of the present invention is to provide a cartridge holding device capable of reliably and immovably holding a tape cartridge in a cartridge mounting portion without impairing the ease of attachment / detachment, and a tape printing device provided with the cartridge holding device.

【0005】

[Means for solving problems]

The cartridge holding mechanism of the present invention includes a cartridge mounting portion to which the tape cartridge is detachably mounted and an opening / closing lid for opening and closing the cartridge mounting portion, and the tape cartridge can be opened with the opening / closing lid closed. In the cartridge holding device held in the cartridge mounting portion, a pair of pinching urging means provided in the cartridge mounting portion and holding and urging the tape cartridge at two opposite locations in the direction orthogonal to the mounting direction, and an opening / closing lid. The tape cartridge is provided with a pressing urging means for pressing and urging the tape cartridge toward the bottom surface of the cartridge mounting portion when the opening / closing lid is closed.

【0006】

According to this configuration, when a tape cartridge is mounted on the cartridge mounting portion, a pair of pinching urging means pinches and urges the tape cartridge from a direction (horizontal direction) orthogonal to the mounting direction (vertical direction) to hold the tape cartridge. When the tape cartridge is held immovably in the horizontal direction and the opening / closing lid is closed from this state, the pressing urging means presses the tape cartridge from the mounting direction toward the bottom surface of the cartridge mounting portion to push the tape cartridge in the vertical direction. Hold it immovably. That is, when the tape cartridge is mounted on the cartridge mounting portion and the opening / closing lid is closed, the tape cartridge is held immovably, and rattling and lifting are surely prevented. On the other hand, when the opening / closing lid is opened and the tape cartridge is attached / detached, the pressing by the pressing urging means is released, and the tape cartridge is engaged and disengaged in the direction orthogonal to the urging force of the holding urging means. , The tape cartridge can be easily attached to and detached from the cartridge mounting part with a weak force.

【0007】

In this case, each pinching urging means has a holding claw that engages with the recess formed in the tape cartridge and a spring that urges the holding claw, and the engaging portion between the holding claw and the recess is the spring. It is preferable that the tape cartridge is formed in a shape that exerts a component force that receives a spring force and presses the tape cartridge against the bottom surface of the cartridge mounting portion.

【0008】

According to this configuration, the holding claws of the holding urging means can not only hold and urge the tape cartridge in the horizontal direction, but also press and urge the tape cartridge in the vertical direction by the component force of the urging force. Therefore, the tape cartridge can be held so as to be strongly pressed against the bottom surface of the cartridge mounting portion together with the pressing urging means.

【0009】

In these cases, it is preferable that the pressing urging means is composed of a pair of pressing mechanisms arranged apart from each other.

【0010】

According to this configuration, the tape cartridge can be pressed against the bottom surface of the cartridge mounting portion with a uniform force in the vertical direction.

【0011】

In this case, the cartridge mounting portion is provided with a print head facing the tape cartridge and a detection switch for detecting the tape cartridge, and one of the pair of pressing mechanisms presses the position near the print head on the tape cartridge. On the other hand, it is preferable to press and urge the position of the tape cartridge facing the detection switch.

【0012】

According to this configuration, it is possible to reliably hold down the portion near the print head and the portion of the detection switch that have the most adverse effect due to the sticking or floating of the tape cartridge. Therefore, it is possible to directly prevent printing defects and detection errors due to the floating of the tape cartridge.

【0013】

Similarly, the tape cartridge is provided with gripping protrusions that serve as clues for pulling out from the cartridge mounting portion, and it is preferable that at least one of the pair of pressing mechanisms presses and biases the gripping protrusions.

【0014】

According to this configuration, it is not necessary to specially form a portion of the tape cartridge that receives the action end of the pressing mechanism of the pressing urging means, and even if the opening / closing lid is provided with the pressing urging means, it is necessary to change the design of the tape cartridge. There is no.

【0015】

In these cases, each pressing mechanism comprises a pressing claw, a spring for urging the pressing claw, and a pressing claw holder for holding the pressing claw and the spring, and the pressing claw holder is integrally formed on the inner surface of the opening / closing lid. It is preferable that it is.

【0016】

According to this configuration, the pressing claws urged by the spring can be integrally provided on the inner surface of the opening / closing lid via the pressing claw holder, and a stable pressing force can be applied to the tape cartridge. It is possible to effectively prevent damage to the portion.

【0017】

The tape printing apparatus of the present invention includes the cartridge holding apparatus according to any one of claims 1 to 6.

【0018】

According to this configuration, since the tape cartridge can be immovably held in the cartridge mounting portion, it is possible to effectively prevent the detection of the tape cartridge, the skewing and jamming of the tape, and the weak force for attaching and detaching the tape cartridge. Can be done with.

The tip of the pressing claw 51 is formed in a wedge shape, and the pressing claw 51 is slidably held on the inner surface of the pressing claw holder 54 at the base end side half portion. Further, a pair of stopper protrusions 57 are projected on the outer surface of the pressing claw 51 on the base end side, and the stopper protrusions 57 are slidably engaged with the stopper slit 56 of the pressing claw holder 54. ..

【0035】

As shown in FIGS. 3 and 4, the pair of pressing mechanisms 24, 24 configured in this way are arranged in an inverted state, and have exactly the same structure. Then, when the opening / closing lid 6 is closed, the pressing mechanism 24 on the left side abuts on the above-mentioned gripping protrusion 43 formed on the tape cartridge 4 and presses and urges it (see FIG. 6), and the pressing mechanism 24 on the right side The corner of the tape cartridge 4, which is directly above the detection switch 35, is pressed and urged.

【0036】

Then, as shown in FIG. 6, when the standard cartridge 4a having no thickness is pressed and urged, the coil spring 52 of each pressing mechanism (only the pressing mechanism 24 on the left side is shown in the figure) 24 is in a relatively weakly contracted state. When urging this and pressing and urging the thick extra-thick cartridge 4b, the coil spring 52 of each pressing mechanism 24 is urged in a relatively strongly contracted state.

【0037】

As shown in FIGS. 7 and 8, of the pair of holding and urging mechanisms 23a and 23b arranged to face each other, the right holding and urging mechanism 23a has a holding claw 61 that directly engages with the recess 42 of the tape cartridge 4. An auxiliary urging member 62 that slides toward the holding claw 61 by the above-mentioned operating piece 40 formed on the opening / closing lid 6, a coil spring 63 interposed between the holding claw 61 and the auxiliary urging member 62, and a holding claw. It is composed of a claw receiving block 64 that rotatably supports 61, and a cover 65 that covers the auxiliary urging member 62 and the coil spring 63.

【0038】

The holding claw 61 includes a rotating base portion 67 having a substantially circular cross section and rotatably seated on the semicircular receiving portion 64a of the claw receiving block 64, and an L-shaped arm portion 68 extending in an L shape from the rotating base portion 67. And the claw portion 69 formed at the tip of the L-shaped arm portion 68 are integrally formed. The claw portion 69 is formed with an inclined surface 69a that acts a downward component force with the inclined surface 42a in the recess 42 of the tape cartridge 4. That is, the inclined surface 69a of the claw portion 69 is formed in a shape complementary to the inclined surface 42a of the recess 42, and the inclined surface 69a of the claw portion 69 presses the inclined surface 42a of the recess 42 in the lateral direction. Press the tape cartridge 4 downward (vertically).

【0039】

The auxiliary urging member 62 is freely attached to the square guide hole 70 surrounded by the above-mentioned claw receiving block 64 and the cover 65 formed in a part of the mounting portion case 3, and is attached to the tail end portion thereof. An upward inclined cam surface 71 is formed to engage (contact) the operating piece 40 of the opening / closing lid 6. When the opening / closing lid 6 is closed, the auxiliary urging member 62 advances toward the holding claw 61 by the cam action between the lower end of the operating piece 40 and the inclined cam surface 71.

【0040】

The coil spring 63 is arranged between the tip of the auxiliary urging member 62 and the back surface of the holding claw 61. When the auxiliary urging member 62 advances, the coil spring 63 contracts to tape the holding claw 61. Strongly urge the cartridge 4 side. On the other hand, when the opening / closing lid 6 is opened, the operating piece 40 is separated from the auxiliary urging member 62, the auxiliary urging member 62 is retracted by the coil spring 63, and the spring force of the coil spring 63 is weakened. That is, when the opening / closing lid 6 is closed, the tape cartridge 4 is strongly pinched and urged, and when the opening / closing lid 6 is opened, the tape cartridge 4 is weakly pinched and urged. Although not shown, a stopper for restricting the retracted position of the secondary urging member 62 is provided behind the auxiliary urging member 62.

【0041】

Similarly, the holding claw mechanism 23b on the left side has a holding claw 61 that directly engages with the recess 42 of the tape cartridge 4, a coil spring 63 that urges the holding claw 61 in the holding direction (lateral direction), and a holding claw 61. It is composed of a claw receiving block 64 that rotatably supports the coil spring 63 and a cover 65 that covers the coil spring 63. The coil spring 63 is interposed between the side wall portion of the cover 65 and the holding claw 61, and receives the cover 65 and urges the holding claw 61 in the lateral direction.

【0042】

In this case as well, the holding claw 61 includes a rotating base portion 67 rotatably seated on the receiving portion 64a of the claw receiving block 64, an L-shaped arm portion 68, and a claw portion 69 formed at the tip of the L-shaped arm portion 68. And it is formed integrally. Further, the claw portion 69 cooperates with the recess 42 of the tape cartridge 4 to act a downward component force to press the tape cartridge 4 downward (vertically).

【0043】

Here, with reference to FIGS. 6, 8 and 9, the holding mode of the tape cartridge 4 mounted on the cartridge mounting portion 7 will be described separately for the standard cartridge 4a and the extra-thick cartridge 4b described above. As described above, the standard cartridge 4a and the extra-thick cartridge 4b have different thicknesses, the standard cartridge 4a is seated on the raised block 37, and the extra-thick cartridge 4b is seated on the bottom plate 31. Further, in the mounted state, the gripping protrusion 43 and the recess 42 of the extra-thick cartridge 4b come to a position higher than the gripping protrusion 43 and the recess 42 of the standard cartridge 4a (level from the bottom surface 38). Therefore, the left and right holding claws 61 and 61 are properly engaged with the recess 42 in the standard cartridge 4a, but simply abut on the lower side of the recess 42 in the extra-thick cartridge 4b.

【0044】

Both holding claws 61 and 61 of the left and right holding urging mechanisms 23a and 23b facing each other face in the cartridge mounting portion 7, and the tape cartridge 4 has both holding claws 61 and 61 against each coil spring 63. It is attached by pushing it open. In this mounted state, the tape cartridge 4 is pinched and urged by the coil spring 63 with a relatively weak force, and is pressed against the bottom surface 38 of the cartridge mounting portion 7 with a relatively weak force. Subsequently, when the opening / closing lid 6 is closed, the pair of pressing mechanisms 24, 24 provided on the opening / closing lid 6 strongly press the tape cartridge 4 against the bottom surface 38 of the cartridge mounting portion 7. At the same time, the operating piece 40 of the opening / closing lid 6 presses the holding claw 61 of the holding urging mechanism 23a on the right side via the coil spring 63. As a result, the tape cartridge 4 is strongly pressed against the bottom surface 38 of the cartridge mounting portion 7 and is strongly sandwiched (see FIGS. 6 (a) and 8).

【0045】

On the other hand, as described above, in the extra-thick cartridge 4b, the holding claws 61 of the left and right holding urging mechanisms 23a and 23b do not engage with the recesses 42 of the tape cartridge 4, so that the holding claws 61 press against the bottom surface 38. No force works. However, the thick tape cartridge 4 is strongly pressed against the bottom surface 38 by the pair of pressing mechanisms 24 and 24 (see FIGS. 6 (b) and 9). Further, since both holding claws 61 and 61 are pushed open, the tape cartridge 4 is pinched by a relatively strong force. Therefore, both the standard cartridge 4a and the extra-thick cartridge 4b receive substantially the same spring force, are strongly pressed against the bottom surface 38 of the cartridge mounting portion 7, and are strongly sandwiched.

【0046】

As described above, the tape cartridge 4 is immovably held in the closed cartridge mounting portion 7 by the lateral holding force and the vertical pressing force. Therefore, rattling and floating of the tape cartridge 4 can be effectively prevented, and print quality and stability in detection of the tape cartridge 4 can be improved. Further, when the opening / closing lid 6 is opened, the spring force of the pressing mechanism 24 is released and the pressing state of the holding claw 61 by the operating piece 40 is released, so that the tape cartridge 4 can be easily attached / detached with a weak force. be able to.

【0047】

Further, the tape cartridge 4 is uniformly pressed by the pair of pressing mechanisms 24 and 24, and the vicinity of the print head 32 and the portion facing the detection switch 35 are pressed, so that printing defects and detection errors are effectively prevented. .. Moreover, since the pressing mechanism 24 and the pinching urging mechanisms 23a and 23b urge the tape cartridge 4 using coil springs 52 and 63, unlike urging members such as resin having springiness, the pressing mechanism 24 and the sandwiching urging mechanism 23a and 23b urge the tape cartridge 4. The sagging can be surely prevented.

【0048】

The pressing mechanism is not limited to the two of the embodiments, and may be three or more. Also, the types of tape cartridges are not limited to four types. Further, the pinching urging mechanism does not necessarily have to have a structure in which a component force in the vertical direction is applied.

【0049】

[Effect of the invention]

As described above, according to the tape cartridge holding mechanism of the present invention, the tape cartridge is strongly sandwiched when the opening / closing lid is closed by the sandwiching urging means provided in the cartridge mounting portion and the pressing urging means provided in the opening / closing lid. At the same time, the tape cartridge can be strongly pressed against the bottom surface of the cartridge mounting portion, and the tape cartridge can be easily attached to and detached from the cartridge mounting portion with a weak force when opened. Therefore, the tape cartridge can be reliably and immovably held in the cartridge mounting portion without impairing the ease of attachment / detachment, and printing defects and the like can be effectively prevented.

【0050】

Further, according to the tape printing apparatus of the present invention, since the tape cartridge can be immovably held in the cartridge mounting portion, it is possible to effectively prevent detection errors of the tape cartridge, skewing of the tape, and jamming. The tape cartridge can be attached and detached with a weak force. Therefore, the usability and reliability of the device can be improved.
