Description

The present invention relates to a cassette.

A cassette including a tape and a film, which are print media, is known as a laminate type cassette. When the cassette is mounted on a printer and used, the film is attached to the printing surface after printing is performed on one surface of the tape (hereinafter, referred to as "printing surface"). The tape cartridge described in Patent Document 1 includes a printing tape, a laminated tape (hereinafter referred to as "laminated film"), a feed-driven roller, a sticking arm, a sticking spring, and a protruding claw receiving groove. The tape cartridge is supported by the tape printing device by engaging the protruding claw receiving groove with the inner protruding claw of the tape printing device. The sticking arm is rotatably attached at an intermediate position. The sticking spring is connected to the front end of the sticking arm and urges the front end upward. In response to this urging force, the rear end of the sticking arm urges the feed-driven roller downward. The feed-driven roller sandwiches the printing tape and the laminating film between the feed-driven roller and the feed-driven roller of the tape printing device provided on the lower side. As the feed-driven roller is urged downward, the laminate film is pressed against the printing tape. The printing tape and the laminated film are conveyed while being attached according to the rotation of the feed drive roller.

Japanese Unexamined Patent Publication No. 2000-280538

In order to properly bond the printing tape and the laminating tape, it is preferable that the protrusion claw receiving groove is arranged on the extension line in the direction of the reaction force of the urging force acting on the feed-driven roller. This is because the reaction force acting on the feed-driven roller can be appropriately received by the protrusion claw receiving groove by such an arrangement, so that the positional relationship between the feed-driven roller and the feed-driven roller can be stabilized. is there. However, in the tape cartridge, the positions of the protruding claw receiving groove and the feed driven roller are deviated from each other in the direction of the urging force. Therefore, the tape cartridge may be bent. There is a problem that the occurrence of bending may adversely affect the bonding of the printing tape and the laminated tape by the protruding claw receiving groove and the feed-driven roller.

<How to attach the cassette 1A to the printing device 7A>
The cassette 1A is mounted on the mounting portion 72 of the printing device 7A as follows. First, the user opens the cover 712 of the printing apparatus 7A (see FIG. 7). When the cover 712 is opened, the platen holder 79 of the printing apparatus 7A is arranged in the second position. The cassette 1A is arranged above the mounting portion 72 of the printing device 7A in a state where the front-back and left-right directions coincide with the front-back and left-right directions of the printing device 7A. At this time, the upper end of the head holder 76 is arranged at the lower end of the head opening 26 of the cassette 1A. Next, the user moves the cassette 1A downward toward the mounting portion 72 so that the head holder 76 of the printing device 7A enters the head opening 26 of the cassette 1A. As a result, as shown in FIGS. 8 and 9, the mounting of the cassette 1A on the mounting portion 72 is completed.

As shown in FIG. 9, with the cassette 1A mounted on the mounting portion 72, the rear surface 9A of the pressing member 9 of the printing device 7A is attached to the protruding portion 301 provided on the arm wall 30U of the cassette 1A from the front. Contact. In this case, as shown in FIG. 10, a part of the cassette roller 4B of the cassette 1A and the arm wall 30U of the housing 2 are arranged in this order toward the front. A part of the cassette roller 4B and the arm wall 30U overlap each other in the front-rear direction.

The user then closes the cover 712 (see FIG. 6). The platen holder 79 of the printing apparatus 7A swings from the second position to the first position in the process of closing the cover 712. The platen holder 79 is placed in the first position with the cover 712 closed. As shown in FIG. 10, the platen roller 77 approaches the thermal head 76A of the head holder 76 from the rear. The platen roller 77 comes into contact with the release layer on the rear surface of the printing tape 61 arranged in the gap 28 and pushes the printing tape 61 forward. The platen roller 77 presses the adhesive surface of the printing tape 61 against the ink ribbon 62. The platen roller 77 further urges the printing tape 61, which is overlapped with the ink ribbon 62, to the thermal head 76A of the head holder 76.

Further, the main body roller 78 comes into contact with the release layer on the rear surface of the printing tape 61 on the left side of the platen roller 77. The main body roller 78 sandwiches the printing tape 61 and the film tape 63 between the cassette roller 4B of the cassette 1A in a state where the adhesive surface of the printing tape 61 and the adhesive surface of the film tape 63 overlap. Further, when the cassette roller 4B is pushed forward as the main body roller 78 moves forward, the holder 41 holding the cassette roller 4B also moves forward. Here, the base portion 51 of the transmission member 5 does not move forward because the protruding portion 52B is in contact with the arm wall 30U. Therefore, the distance between the erection portion 41C of the holder 41 and the base portion 51 is shortened, and the spring 54 contracts. The spring 54 urges the holder 41 rearward by an elastic force corresponding to the contraction. Therefore, the cassette roller 4B receives the urging force of the spring 54 via the holder 41 and sandwiches the printing tape 61 and the film tape 63 with the main body roller 78.

<Printing method>
The printing device 7A can execute the printing operation as follows with the cassette 1A mounted on the printing device 7A. As shown in FIG. 8, the printing device 7A rotates the motor M1 to rotate the drive gear G1, the platen roller 77, and the main body roller 78 in a counterclockwise direction in the plan view of FIG. Let me. The platen roller 77 and the main body roller 78 draw out the printing tape 61 from the first tape roll 6A and convey the printing tape 61 along the conveying path T1. Further, the main body roller 78 pulls out the film tape 63 from the second tape roll 6D and conveys the film tape 63 along the conveying path T3. Further, the ribbon winding shaft 75 also rotates with the rotation of the drive gear G1, and the ink ribbon 62 is wound around the winding ribbon roll 6C. As a result, the ink ribbon 62 is conveyed along the transfer path T2.

As shown in FIG. 10, the printing tape 61 and the ink ribbon 62 sandwiched between the thermal head 76A and the platen roller 77 are transported to the downstream side in the transport direction, that is, to the left by the rotating platen roller 77. The printing apparatus 7A heats a plurality of heating elements of the thermal head 76A while conveying the heat as described above. In the gap 28, the thermal head 76A prints an object on the adhesive surface of the printing tape 61 by using the ink ribbon 62 drawn from the supply ribbon roll 6B. The used ink ribbon 62 is peeled off from the printing tape 61 by coming into contact with the rear end of the facing wall 27D of the head peripheral wall 27. The peeled ink ribbon 62 is wound around the winding ribbon roll 6C.

The printing tape 61 and the film tape 63 sandwiched between the cassette roller 4B and the main body roller 78 are conveyed to the downstream side in the conveying direction, that is, to the left by the rotating main body roller 78. The adhesive surface of the film tape 63 is attached to the adhesive surface of the printed printing tape 61 between the cassette roller 4B and the main body roller 78. This creates a label tape. The produced label tape is discharged to the outside of the cassette 1A via the discharge port 22A.

<Action and effect of this embodiment>
The direction of the urging force of the spring 54 acting on the cassette roller 4B of the cassette 1A faces rearward. For example, as shown in FIG. 10, a virtual plane P extending in parallel with the front-rear direction through the rotation center C of the cassette roller 4B is defined. In this case, the direction of the urging force of the spring 54 acting on the cassette roller 4B corresponds to the arrow D1 extending rearward from the rotation center C along the virtual plane P. On the other hand, the direction of the reaction force of the spring 54 with respect to the urging force is in the direction opposite to the arrow D1. In the case shown in FIG. 10, the reaction force corresponds to the arrow D2 extending forward from the rotation center C along the virtual plane P. Then, the cassette roller 4B and the arm wall 30U of the housing 2 are arranged in order in the direction (forward) in which the arrow D2 faces. Further, the entire cassette roller 4B and the arm wall 30U overlap in the front-rear direction. Therefore, the cassette 1A can appropriately receive the reaction force acting on the cassette roller 4B according to the urging force of the spring 54 by the arm wall 30U of the housing 2. In this case, even if a reaction force corresponding to the urging force of the spring 54 acts on the cassette roller 4B, the cassette roller 4B is suppressed from moving forward. Therefore, since the cassette 1A can stabilize the position of the cassette roller 4B in the front-rear direction, the printing tape 61 and the film tape 63 can be appropriately bonded by the cassette roller 4B.

For example, when the arm wall 30U of the housing 2 is arranged above the tape spool 60D in the front-rear direction, the tape spool 60D of the cassette 1A is provided at a position substantially in the front-rear direction from the center in the housing 2. The width in the left-right direction at the position increases. In this case, it hinders the miniaturization of the cassette 1A, which is not preferable. On the other hand, in the cassette 1A, the arm wall 30U is arranged between the cassette roller 4B and the tape spool 60D in the front-rear direction. In this case, the width in the left-right direction can be reduced at a position on the housing 2 from substantially the center in the front-rear direction to the front side, that is, at a position of the cassette 1A where the tape spool 60D is provided. Therefore, the cassette 1A can make the housing 2 smaller by effectively utilizing the space between the cassette roller 4B and the tape spool 60D.

The arm wall 30U extends to the left from the left wall 20L orthogonal to the left-right direction in the housing 2. In this case, the cassette 1A can easily form the arm wall 30U for bringing the protruding portion 52B of the transmission member 5 into contact with a part of the housing 2.

The holding portion 4 of the cassette 1A has a holder 41 that comes into contact with the spring 54 of the transmission member 5. The holder 41 rotatably supports both ends of the rotation shaft of the cassette roller 4B in the vertical direction. In this case, the cassette 1A can stably hold the cassette roller 4B by the holder 41.

<Modification example>
The present invention is not limited to the above embodiment, and various modifications can be made. In the above, the entire cassette roller 4B and the arm wall 30U of the housing 2 overlap each other in the front-rear direction. On the other hand, a part of the cassette roller 4B may overlap the arm wall 30U in the front-rear direction. The protrusion 301 may not be provided on the arm wall 30U of the cassette 1A. In this case, with the cassette 1A mounted on the mounting portion 72 of the printing device 7A, the entire front surface of the arm wall 30U may come into contact with the rear surface 9A of the pressing member 9.

The arm wall 30U may not be provided on the cassette 1A. The left wall 20L of the cassette 1A may extend in the front-rear direction together with the arm wall 30L. The protruding portion 52B of the transmission member 5 of the arm wall 30L may come into contact with the left end portion of the front wall 20F of the housing 2 from the inside.

The protrusion 52B of the transmission member 5 does not have to come into contact with the arm wall 30U of the housing 2 from the inside. For example, in the cassette 1A, the left wall 20L may be provided from the front end portion to the rear end portion of the housing 2. Further, the housing 2 is a plate body protruding to the right from the inner surface of the left wall 20L, and may have a plate body orthogonal to the front-rear direction in front of the transmission member 5. The protruding portion 52B of the transmission member 5 may come into contact with the plate body from behind.

The amount of protrusions 52A to 52C of the transmission member 5 in the forward direction may be the same. In this case, the tips of the protrusions 52A to 52C may come into contact with the inner surface of the arm wall 30U of the housing 2. The transmission member 5 may have one protruding portion in which the protruding portions 52A to 52C are integrated and extends in the vertical direction.

The cassette 1A may be provided with a left wall 20L from the front end portion to the rear end portion of the housing 2. The left wall 20L may be provided with a recess recessed toward the right. When the cassette 1A is mounted, the pressing member 9 of the printing device 7A may engage with the recess by entering from the lower end of the recess and moving upward in the recess. The recess may have a first portion and a second portion having different widths in the front-rear direction. The width of the first part may be smaller than the width of the second part. In this case, the pressing member 9 that engages with the recess may be in close contact with the recess in the first portion. The protruding portion 52B of the transmission member 5 may come into contact with the portion of the recess corresponding to the first portion from the inside of the housing 2. In this case, the position of the cassette 1A with respect to the printing apparatus 7A is particularly well-positioned in the first portion of the recess. Therefore, the cassette 1A can accurately position the cassette 1A with respect to the printing apparatus 7A by bringing the protruding portion 52B of the transmission member 5 into contact with the first portion of the recess having a relatively small width.

Further, the recess may have a first wall and a second wall facing each other in the front-rear direction. The first wall may be located behind the second wall. The first wall may have a first overhang that projects toward the second wall. The second wall may have a second overhang that overhangs the first wall. The protruding portion 52B of the transmission member 5 may come into contact with the portion of the first wall where the first protruding portion is provided in the vertical direction from the inside of the housing 2. In this case, since the width of the recess can be easily adjusted, the housing 2 capable of accurately positioning the cassette 1A with respect to the printing apparatus 7A can be easily generated.

Further, the tip of the first overhanging portion may have a first inclined portion that is inclined upward in a direction close to the second overhanging portion. The tip of the second overhanging portion may have a second inclined portion that is inclined upward in a direction close to the first overhanging portion. In this case, when the cassette 1A is mounted, the pressing member 9 of the printing device 7A enters from the lower end of the recess and moves upward in the recess, and the pressing member 9 has a first inclined portion and a second inclined portion. Guided inside the recess along the way to engage the recess. Further, the protruding portion 52B of the transmission member 5 may come into contact with a portion of the first wall above the position where the first inclined portion is provided in the vertical direction from the inside. In this case, in the process of mounting the cassette 1A on the printing device 7A, the pressing member 9 of the printing device 7A can be smoothly guided to the recess of the cassette 1A. Further, since the protruding portion 52B of the transmission member 5 comes into contact with the first portion of the recess having a relatively small width, the cassette 1A can be accurately positioned with respect to the printing device 7A.

Further, in the above, the center of the printing tape 61 in the vertical direction and a part of the first overhanging portion and the second overhanging portion may overlap in the front-rear direction. In this case, the reaction force of the urging force of the spring 54 acting on the cassette roller 4B when the printing tape 61 and the film tape 63 are sandwiched between the cassette roller 4B and the main body roller 78 is applied to the center of the printing tape 61 in the vertical direction. , Can be appropriately received by the first overhanging portion and the second overhanging portion of the recess.

The cassette 1A may include a non-rotating member (for example, a blade) instead of the cassette roller 4B. The printing tape 61 and the film tape 63 may be attached to each other by being sandwiched between the non-rotating member and the main body roller 78. The printing device 7A may have a positioning portion protruding from the cover 712 instead of the pressing member 9.
