Abstract

PROBLEM TO BE SOLVED: To provide a miniaturized cassette. A cassette can be attached to a printing apparatus having a transport roller. The cassette includes a tape spool, a holding member 110, and a spring 140. The first tape is wound around the tape spool. The sandwiching member 110 is provided at a position facing the transfer roller when mounted on the printing apparatus, and can sandwich the first tape unwound from the tape spool in cooperation with the transfer roller. The spring 140 comes into direct contact with the holding member 110 and urges it forward toward the transport roller. Since the spring 140 directly urges the holding member 110, the cassette can be miniaturized as compared with the case where the spring 140 urges the holding member 110 via another member.

Description

The present invention relates to a cassette that can be attached to a printing apparatus.

Cassettes that can be mounted on printing devices are known. For example, a tape cartridge is attached to the tape printing apparatus disclosed in Patent Document 1. The tape cartridge includes both springs, both arms, and a feed driven roller. The urging force of both springs is transmitted to the driven roller via both arms. The urged feed-driven roller sandwiches the printing tape and the laminating tape in cooperation with the feed driving roller of the printing apparatus.

Japanese Unexamined Patent Publication No. 2000-280538

However, since the tape cartridge is provided with both arms, the tape cartridge may become large in size.

An object of the present invention is to provide a miniaturized cassette.

The cassette according to the first aspect of the present invention is a cassette that can be attached to a printing apparatus having a conveying roller, and includes a first tape roll on which the first tape is wound and a conveying roller when attached to the printing apparatus. The first tape, which is provided at the opposite position and is unwound from the first tape roll, comes into direct contact with the holding member that can hold the first tape in cooperation with the transfer roller and urges the transfer roller. It is characterized by having a spring. According to the above configuration, since the spring directly urges the holding member, the cassette can be miniaturized.

In the present invention, the sandwiching member is formed with a through hole penetrating in the width direction of the first tape, and the spring may be a coil spring inserted through the through hole. Since the spring is inserted through the holding member, the cassette can be further miniaturized.

In the present invention, the holding member may be a roller rotatably provided with respect to the spring. Since the sandwiching member is a roller, the first tape is more stably conveyed.

In the present invention, a holder that holds a spring and is lined up with the roller with a gap along the axial direction of the roller and a spring that bends when the holding member is urged may enter the gap. Since the space where the spring bends can be secured, the spring can stably urge the holding member.

In the present invention, the roller may include an inner peripheral surface surrounding the hole into which the spring is inserted, and a convex portion that is convex from the inner peripheral surface toward the axis of the roller. Since the position of the core, which is the center of rotation of the roller, can be adjusted, the force with which the roller sandwiches the first tape with the conveying roller tends to be appropriate.

The cassette according to the second aspect of the present invention is a cassette that can be mounted on a printing device having a transport roller, and is a cassette on which a first tape is wound and a transport roller when mounted on the printing device. A holding member provided at a position facing the first tape roll and capable of holding the first tape unwound from the first tape roll in cooperation with the transport roller, and a protruding portion protruding from the holding member in the axial direction of the transport roller. It is characterized by being provided with a spring that comes into direct contact with the portion and urges the transfer roller. According to the above configuration, the spring urges the protruding portion at a position deviated from the holding member in the axial direction of the transport roller. Since the space of the cassette in the direction orthogonal to the axial direction of the transfer roller is reduced, the cassette can be miniaturized.

In the present invention, the springs may be provided on one side and the other side in the axial direction of the transport roller with respect to the holding member. Since the two springs urge the holding member, the cassette can stably urge the holding member toward the transport roller.

In the present invention, the spring may be a torsion coil spring. Compared with the case where the spring is, for example, a coil spring, the space of the cassette in the direction orthogonal to the axial direction of the transport roller is smaller. Therefore, the cassette can be further miniaturized.

The present invention may include a regulating portion that regulates the movement of the holding member in the axial direction of the transport roller. In the cassette, the position of the holding member in the axial direction of the transport roller can be prevented from being displaced.

The present invention includes a second tape roll on which a second tape different from the first tape is wound, and the sandwiching member may sandwich the overlapping first tape and the second tape in cooperation with a transport roller. .. Since the second tape is sandwiched between the sandwiching member and the transport roller in addition to the first tape, the sandwiching force of the sandwiching member is strengthened. Therefore, the first tape and the second tape are easily conveyed.

In the first tape 8, the ink ribbon 4 is separated by the ribbon separating portion 68 and extends to the discharging portion 69.

<Structure of holding mechanism 100>
The sandwiching mechanism 100 will be described with reference to FIGS. 5 and 6. The pinching mechanism 100 is a mechanism for sandwiching the first tape 8 with the transport roller 31 (see FIG. 3). The pinching mechanism 100 includes a holder 106, a spring 140, and a pinching member 110.

The holder 106 has a box shape that opens toward the front, and is integrally formed with the housing 60 (see FIG. 3). The holder 106 includes a pair of wall portions 121, a pair of regulating portions 122, and a pair of spring regulating portions 132. The pair of wall portions 121 are arranged along the vertical direction. The pair of restricting portions 122 are arranged along the vertical direction between the pair of wall portions 121. Each regulating portion 122 is formed by a pair of plate-shaped members 122A and 122B arranged at intervals in the left-right direction. The thickness direction of the plate-shaped members 122A and 122B is the vertical direction. The pair of spring restricting portions 132 are arranged between the pair of wall portions 121 and outside the pair of restricting portions 122 in the vertical direction. Each spring regulating portion 132 is formed by regulating pieces 132A and 132B arranged at intervals along the front-rear direction.

The spring 140 of this example is a coil spring arranged between a pair of wall portions 121, and is formed spirally along the vertical direction. The spring 140 is in contact with each of the pair of wall portions 121 in a vertically compressed state, and is arranged between the regulation pieces 132A and 132B and between the pair of plate-shaped members 122A. The spring 140 can be elastically displaced by bending in the front-rear direction, and the amount of bending is regulated by a pair of regulating pieces 132A and 132B. That is, the spring regulating unit 132 regulates the amount of deflection of the spring 140 so as not to exceed a predetermined amount.

The sandwiching member 110 is arranged between the pair of regulating portions 122. The sandwiching member 110 of this example is a roller whose axial direction is the vertical direction. The sandwiching member 110 is formed with a through hole 119 that penetrates in the vertical direction, which is the width direction of the first tape 8, and the spring 140 is inserted through the through hole 119 and comes into direct contact with the sandwiching member 110. The holding member 110 is rotatably provided on the spring 140. When the cassette 6 is mounted on the cassette mounting portion 22, the holding member 110 is in a position facing the transport roller 31 (see FIG. 3). The vertical movement of the sandwiching member 110 is regulated by a pair of restricting portions 122 of the holder 106. One of the pair of spring regulating portions 132 is aligned with the holding member 110 as a roller with a gap 41 in the vertical direction, and the other of the pair of spring regulating portions 132 is sandwiched with a gap 42 in the vertical direction. Along with member 110. That is, the sandwiching member 110 is aligned with the pair of spring restricting portions 132 of the holder 106 with gaps 41 and 42 in the vertical direction. The vertical width of the gap 41 corresponds to the dimension L1, and the vertical width of the gap 42 corresponds to the dimension L2.

<Printing procedure>
The printing procedure will be described with reference to FIGS. 2, 3, and 6. The cassette 6 is mounted on the cassette mounting portion 22. The ribbon winding shaft 33 of the printing device 1 is inserted into the ribbon winding spool 76 of the cassette 6. The head holder 291 is inserted into the head insertion portion 62.

As the cassette cover 3 moves to the closed position, the platen holder 38 moves from the standby position to the printing position (arrow Y11, see FIG. 3). The platen roller 30 superimposes the first tape 8 and the ink ribbon 4 and presses them against the thermal head 29. At the same time, the transport roller 31 presses the first tape against the holding member 110. When the sandwiching member 110 is displaced rearward (see arrows R1 and FIG. 6), the spring 140 is flexed rearward and elastically displaced. At this time, the spring 140 enters the gaps 41 and 42, and the amount of deflection of the spring 140 is regulated by the respective regulation pieces 132A of the pair of spring regulation portions 132. The bent spring 140 urges the holding member 110 toward the transport roller 31. As a result, the first tape 8 is sandwiched between the transport roller 31 and the sandwiching member 110 with an appropriate force.

The heat generated by the thermal head 29 heats the ink ribbon 4. As a result, the ink of the ink ribbon 4 is transferred to the base material of the first tape 8. As described above, information such as characters is printed. Of the first tape 8, the surface on which information can be visually recognized by printing is referred to as a “display surface”. Of the first tape 8, the surface opposite to the display surface is referred to as a "non-display surface". In the case of the receptor type cassette 6, the surface of the base material of the first tape 8 to which the ink of the ink ribbon 4 is transferred corresponds to the “display surface”. When the release paper is attached to the base material, the surface of the release paper opposite to the base material side corresponds to the "non-display surface". On the other hand, when the release paper is peeled off from the base material, the side of the base material opposite to the display surface corresponds to the "non-display surface".

As shown in FIG. 3, the ribbon take-up spool 76, the platen roller 30, and the transfer roller 31 rotate as the drive motor is driven. The ink ribbon 4 used for printing is separated from the printed first tape 8 by the ribbon separating portion 68 and wound on the ribbon winding spool 76. The printed first tape 8 from which the ink ribbon 4 is separated is discharged from the discharge unit 69 to the outside of the cassette 6 by the drive rotation of the transport roller 31 and the driven rotation of the holding member 110. The ejected printed first tape 8 is ejected to the outside of the printing apparatus 1 through the apparatus ejection port 26. When the operation for cutting the first tape 8 is executed via the input unit 11, the cutting mechanism 15 is driven. The moving blade 18 moves in a direction close to the fixed blade 16 and cuts the discharged first tape 8.

As described above, the cassette 6 can be mounted on the printing apparatus 1 having the transport roller 31. The cassette 6 includes a tape spool 72, a holding member 110, and a spring 140. The first tape 8 is wound around the tape spool 72. The sandwiching member 110 is provided at a position facing the transport roller 31 when mounted on the printing device 1, and can sandwich the first tape 8 unwound from the tape spool 72 in cooperation with the transport roller 31. The spring 140 comes into direct contact with the holding member 110 and urges the transfer roller 31. According to the above configuration, since the spring 140 directly urges the holding member 110, the cassette 6 can be miniaturized as compared with the case where the spring 140 urges the holding member 110 via another member.

The sandwiching member 110 is formed with a through hole 119 that penetrates in the vertical direction, which is the width direction of the first tape 8. The spring 140 is a coil spring inserted through the through hole 119. Since the spring 140 is inserted through the holding member 110, the cassette 6 can be further miniaturized.

The holding member 110 is a roller rotatably provided with respect to the spring 140. Since the sandwiching member 110 is a roller, the first tape 8 is stably conveyed between the sandwiching member 110 and the conveying roller 31.

One of the pair of spring restricting portions 132 of the holder 106 is aligned with the sandwiching member 110 with a gap 41 along the vertical direction which is the axial direction of the sandwiching member 110, and the other of the pair of spring restricting portions 132 is in the vertical direction. Along the line with the holding member 110 with a gap 42. The spring 140 that bends when the holding member 110 is urged enters the gaps 41 and 42 shown in FIG. Since the space for bending the spring 140 can be secured, the spring 140 can stably urge the holding member 110.

The cassette 6 includes a pair of regulating units 122. The regulating unit 122 regulates the movement of the holding member 110 in the vertical direction, which is the axial direction of the transport roller 31. The cassette 6 can prevent the position of the holding member 110 from being displaced in the axial direction of the transport roller.

In the above description, the tape roll 80 is an example of the "first tape roll" of the present invention.

<Modification example (cassette 6A)>
The cassette 6A of the cassette 6 will be described with reference to FIG. 7. The same components as those in the above embodiment are designated by the same reference numerals in the drawings, and the description thereof will be omitted (the same applies to the description of the following modification examples).

The cassette 6A is a laminated type. The cassette 6A has the same housing 60 as the receptor type cassette 6. The cassette 6A is different from the receptor type cassette 6 in that the support hole 711 rotatably supports the film spool 77 and the tape boss 714 rotatably supports the tape spool 79.

The film spool 77 rotatably supports the film roll 81. A second tape 87 is wound around the film roll 81. The second tape 87 is a double-sided adhesive film. A release paper is attached to one surface of the second tape 87. The second tape 87 extends forward from the film roll 81, winds around the holding member 110, bends to the left, and extends to the discharge portion 69.

The tape spool 79 rotatably supports the tape roll 82. A first tape 89 made of a transparent base material is wound around the tape roll 82. The first tape 89 extends downward from the tape roll 82, passes through the right side of the ribbon spool 74, bends to the left, and extends toward the arm opening 67. At the arm opening 67, the ink ribbon 4 is superposed on the first tape 89. The overlapped first tape 89 and the ink ribbon 4 are exposed to the outside from the arm opening 67 and are conveyed to the ribbon separating portion 68. The ink ribbon 4 is separated from the first tape 89 by the ribbon separating portion 68 and extends to the ribbon winding spool 76. In the first tape 89, the ink ribbon 4 is separated by the ribbon separating portion 68, and the ink ribbon 4 is overlapped with the second tape 87 in front of the holding member 110. The overlapped first tape 89 and second tape 87 extend to the discharge portion 69.

The printing operation by the printing device 1 in which the cassette 6A is mounted on the cassette mounting unit 22 is executed as follows. In response to the rotation of the ribbon winding shaft 33 (see FIG. 3) inserted into the ribbon winding spool 76, the ribbon winding spool 76 pulls out the ink ribbon 4 from the ribbon roll 40 and winds it. The platen roller 30 (see FIG. 3) superimposes the first tape 89 and the ink ribbon 4 and presses them against the thermal head 29. Due to the heat generated by the thermal head 29, the ink of the ink ribbon 4 is transferred to the first tape 89. The platen roller 30 and the transport roller 31 are driven and rotated, and the holding member 110 is driven and rotated. As a result, the first tape 89, the ink ribbon 4, and the second tape 87 are conveyed.

The printed first tape 89 from which the ink ribbon 4 is separated is pressed against the second tape 87 by the holding member 110 and the transport roller 31 and attached. The attached first tape 89 and second tape 87 are discharged from the discharge unit 69 to the outside of the cassette 6 by the rotation of the transport roller 31 and the holding member 110.

The cassette 6A includes a film roll 81 on which a second tape 87 different from the first tape 89 is wound. The sandwiching member 110 sandwiches the first tape 89 and the second tape 87 that overlap each other in cooperation with the transport roller 31. In this modification, since the second tape 87 is sandwiched between the holding member 110 and the transport roller 31 in addition to the first tape 89, the amount of deflection of the spring 140 when the platen holder 38 moves to the printing position is Increase. Since the urging force of the spring 140 increases, the force with which the holding member 110 sandwiches the first tape 89 and the second tape 87 in cooperation with the transport roller 31 increases. Therefore, the conveying force, which is the force by which the conveying roller 31 and the holding member 110 convey the first tape 89 and the second tape 87, increases. Therefore, the first tape 89 and the second tape 87 are easily conveyed.

In this modification, the tape roll 82 is an example of the "first tape roll" of the present invention. The film roll 81 is an example of the "second tape roll" of the present invention.

<Modification example (holding mechanism 100A)>
The sandwiching mechanism 100A, which is a first modification of the sandwiching mechanism 100, will be described with reference to FIG. The sandwiching mechanism 100A may be provided on any of the cassettes 6 and 6, but a modified example provided on the cassette 6 will be described below. The cassette 6 provided with the holding mechanism 100A includes a tape roll 80 (see FIG. 3) around which the first tape 8 is wound, but detailed illustration thereof is omitted (the same applies to the holding mechanisms 100B, 100C, and 100D described later). is there.).

The sandwiching mechanism 100A includes a sandwiching member 110A instead of the sandwiching member 110. The sandwiching member 110A is a roller provided with a hole 118 penetrating in the vertical direction. A spring 140 is inserted into the hole 118, and the holding member 110A is rotatable with respect to the spring 140.

The sandwiching member 110A includes an inner peripheral surface 104 and a convex portion 105 formed integrally with each other. The inner peripheral surface 104 surrounds the hole 118 into which the spring 140 is inserted. The convex portion 105 is convex from substantially the center of the inner peripheral surface 104 in the vertical direction toward the axis of the holding member 110 as a roller, and is substantially annular in a plan view. The convex portion 105 comes into direct contact with the spring 140. In other words, the spring 140 comes into direct contact with the holding member 110. The convex portion 105 holds the spring 140, and the position of the holding member 110A in contact with the spring 140 can be adjusted in the vertical direction. A gap 41A is provided between the spring 140 and the inner peripheral surface 104 so that the spring 140 can enter by bending. The gaps 41A are formed on both sides in the vertical direction with respect to the convex portion 105.

As the platen holder 38 (see FIG. 3) moves from the standby position to the printing position, the sandwiching member 110A sandwiches the first tape 8 in cooperation with the transport roller 31. At this time, the holding member 110 is pushed backward (arrow R2), the spring 140 bends backward, and enters the gap 41A shown in FIG.

In the first modification, the position where the convex portion 105 of the holding member 110 contacts the spring 140 is adjusted in the vertical direction, so that the position of the core which is the rotation center of the holding member 110 can be adjusted. The force with which 110 sandwiches the first tape 8 with the transport roller 31 tends to be appropriate.

<Modification example (holding mechanism 100B)>
The sandwiching mechanism 100B, which is a second modification of the sandwiching mechanism 100, will be described with reference to FIG. The sandwiching member 110B includes a holder 106B, a shaft 159, a sandwiching member 110B, and a pair of springs 140B. The holder 106B includes a pair of facing wall portions 151 and a flat plate portion 152. The pair of facing wall portions 151 face each other in the vertical direction. Each facing wall portion 151 is provided with an elongated hole 151A that is long in the vertical direction. The flat plate portion 152 is a flat plate having a thickness in the front-rear direction, and is connected to each of the pair of facing wall portions 151. The flat plate portion 152 of this example is integrally formed with a pair of facing wall portions 151. The flat plate portion 152 is provided with a pair of bosses 152A that project forward. In FIG. 9, only one boss 152A is shown.

The shaft 159 extends in the left-right direction and is inserted into a pair of elongated holes 151A. The sandwiching member 110B is a roller rotatably provided on the shaft 159. When the cassette 6 (see FIG. 3) is mounted on the cassette mounting portion 22, the holding member 110B is in a position facing the transport roller 31 (see FIG. 3). Each portion of the shaft 159 that protrudes from the holding member 110B on both sides in the vertical direction is a protruding portion 159B. The pair of springs 140B are coil springs formed spirally along the left-right direction. Each spring 140B is fitted into each boss 152A and comes into direct contact with each protrusion 159B.

When the platen holder 38 (see FIG. 3) is in the standby position, each protrusion 159B is positioned in contact with the front end of each elongated hole 151A by the urging force of each spring 140B. When the platen holder 38 moves from the standby position to the printing position, the transport roller 31 (see FIG. 3) pushes the holding member 110 backward with the first tape 8 in between. The pair of springs 140B are compressed to urge the holding member 110 toward the transfer roller 31.

The pinching mechanism 100B includes a protrusion 159B and a spring 140B. The protruding portion 159B protrudes from the holding member 110 toward the outside in the vertical direction, which is the axial direction of the transport roller 31. The spring 140B comes into direct contact with the pair of protrusions 159B and urges the transfer roller 31. The spring 140B urges the protrusion 159B at a position deviated from the holding member 110B in the vertical direction, which is the axial direction of the transport roller 31. Since the space of the cassette 6 (see FIG. 2) in the left-right direction, which is the direction intersecting the axial direction of the transport roller 31, is reduced, the cassette 6 can be miniaturized.

<Modification example (holding mechanism 100C)>
The sandwiching mechanism 100C, which is a third modification of the sandwiching mechanism 100, will be described with reference to FIG. The pinching mechanism 100C includes a holder 106C, a pair of springs 140C, and a pinching member 110C. The holder 106C is different from the holder 106B (see FIG. 9) in that the flat plate portion 153 is provided instead of the flat plate portion 152 (see FIG. 9). The flat plate portion 153 includes a pair of bosses 153A that project upward.

The sandwiching member 110C is different from the sandwiching members 110, 110A, 110B in that it is not a rotatably provided roller. The sandwiching member 110C includes a plate-shaped portion 161 integrally formed with each other, a pair of first protrusions (not shown), and a pair of protrusions 162. The plate-shaped portion 161 has a rectangular shape extending in the vertical direction when viewed from the front. When the cassette 6 (see FIG. 3) is mounted on the cassette mounting portion 22 (see FIG. 3), the plate-shaped portion 161 is in a position facing the transport roller 31. The pair of first protrusions are bosses that protrude rearward from the plate-shaped portion 161 and are provided side by side in the vertical direction. The pair of projecting portions 162 project outward from the plate-shaped portion 161 in the vertical direction. Each protrusion 162 is inserted into the elongated hole 151A of the holder 106C. The pair of springs 140C have the same shape as the pair of springs 140B (see FIG. 9). Each spring 140C fits into each boss 153A and each first protrusion. Therefore, the spring 140C comes into direct contact with the sandwiching member 110C.

When the platen holder 38 (see FIG. 3) is in the standby position, each protrusion 162 is positioned in contact with the front end of each elongated hole 151A by the urging force of the pair of springs 140C. When the platen holder 38 moves from the standby position to the printing position, the transport roller 31 (see FIG. 3) pushes the plate-shaped portion 161 of the holding member 110C rearward with the first tape 8 in between. The pair of springs 140C are compressed to urge the plate-shaped portion 161 of the holding member 110 toward the transport roller 31. As the transfer roller 31 rotates in response to the drive of the drive motor, the first tape 8 between the transfer roller 31 and the plate-shaped portion 161 is conveyed. Also in the third modification, since the pair of springs 140C directly urges the holding member 110C, the cassette 6 can be miniaturized.

<Modification example (holding mechanism 100D)>
The sandwiching mechanism 100D, which is a fourth modification of the sandwiching mechanism 100, will be described with reference to FIG. The pinching mechanism 100D includes a pair of facing wall portions 251 and a shaft 252, a pinching member 110D, and a pair of springs 140D. The pair of facing wall portions 251 face each other in the vertical direction. Each facing wall portion 251 includes an elongated hole 251A that is long in the front-rear direction. The shaft 252 extends in the vertical direction and is inserted into the pair of elongated holes 251A. The sandwiching member 110D is a roller rotatably provided on the shaft 252, and is provided between the pair of facing wall portions 251. When the cassette 6 (see FIG. 3) is mounted on the cassette mounting portion 22 (see FIG. 3), the holding member 110D is in a position facing the transport roller 31. Of the shaft 252, the portions protruding outward from the holding member 110D in the vertical direction are a pair of protruding portions 252A. The pair of springs 140D are provided on one side (upper side in this example) and the other side (lower side in this example) of the transfer roller 31 (see FIG. 3) in the vertical direction, respectively, with respect to the holding member 110D. It is a torsion coil spring provided. Each spring 140D includes a first arm that comes into direct contact with each protrusion 252A and a second arm that comes into contact with another member (not shown). That is, each of the pair of springs 140 comes into direct contact with the pair of protrusions 252A and urges them toward the transport roller 31.

In the fourth modification, since the two springs 140D urge the holding member 110D, the cassette 6 can stably urge the holding member 110D toward the transport roller 31. The spring 140D is a torsion coil spring. Compared with the case where the spring 140 is, for example, a coil spring or the like, the spring 140D becomes smaller in the horizontal direction orthogonal to the vertical direction which is the axial direction of the transport roller 31. Therefore, since the space of the cassette 6 in the left-right direction becomes small, the cassette 6 can be miniaturized.
