Description

  The present invention includes a supply core storage body including a heat transfer sheet, a supply core around which the heat transfer sheet is wound, and a storage case that rotatably holds the supply core, a supply core storage body, and a winding core that is fed from the supply core storage body. The present invention relates to a thermal transfer sheet body provided, and a combination of a thermal transfer sheet body and a thermal transfer sheet body cassette that houses the thermal transfer sheet body.

  Conventionally, a thermal transfer sheet is incorporated in a printer as a thermal transfer sheet body including a thermal transfer sheet, a winding core around which the thermal transfer sheet is wound, and a supply core. In the printer, the thermal transfer sheet is fed from the supply core and heated by the thermal head while being taken up by the take-up core, and the image is transferred to the image receiving sheet.

  Such a thermal transfer sheet is formed by applying ink with a film thickness of about 0.4 to 1 μm to a base sheet, and is very easily damaged. Therefore, in the distribution process, there is a possibility that the supply core around which the thermal transfer sheet is wound comes into contact with the winding core and other objects and damages the thermal transfer sheet. Similarly, there is a risk that the thermal transfer sheet may be damaged when the thermal transfer sheet body is incorporated into the printer.

  In order to solve such a problem, the thermal transfer sheet body is shipped in a state of being stored in a dedicated thermal transfer sheet body cassette, and then is put into a distribution process. Eventually, the thermal transfer sheet member is incorporated into the printer by the user while being stored in the thermal transfer sheet member cassette. When the thermal transfer sheet is used up, the thermal transfer sheet body cassette is discarded together with the thermal transfer sheet body, and a new combination of the thermal transfer sheet body and the thermal transfer sheet body cassette is incorporated in the printer.

  Such a cassette for a thermal transfer sheet body includes a core holding body having a core holding portion for holding a supply core and a core holding portion for holding a winding core, and a lid body that covers these core holding bodies ( For example, Patent Document 1). Further, the winding core and the supply core are normally pressed in one direction by a spring in the thermal transfer sheet cassette.

  The winding core and the supply core are pressed in one direction, the rotation is restricted by the engaging portion provided in the cassette, and the thermal transfer sheet is prevented from being loosened.

  On the other hand, in use, the winding core and the supply core are moved against the force of the spring by an external drive mechanism and released from the engaging portion. As a result, the take-up core and the supply core can be rotated and rotated by the drive mechanism.

That is, by providing a spring, the thermal transfer sheet is prevented from being wound back and damaged from the supply core and the winding core when not in use.

As shown in FIG. 3, the pair of hinges are aligned on a straight line L in a side view from one side of the thermal transfer sheet cassette 40. Therefore, the end wall 41 is swingably connected to the supply core housing holding part 51 and the take-up core holding part 61 with a pair of hinges formed by the support shafts 58 and 68 and the receiving grooves 43a and 43b as axes. Is done.

  As described above, the end wall 41 is inserted into the engagement openings 53a and 63a of the support plates 53 and 63 of the supply core storage body holding part 51 and the winding core holding part 61, respectively. , 42b. For this reason, as shown in FIG. 7, when the end wall 41 is swung, the support plates 53 and 63 warp through the engagement between the engagement plates 42a and 42b and the engagement openings 53a and 63a. In this case, as described above, the support plates 53 and 63 function as leaf springs, and a restoring force is generated to return to the positions shown in FIGS. Therefore, when the external force that tries to swing the end wall 41 is eliminated, the support plates 53 and 63 and the end wall 41 are automatically returned to the positions shown in FIGS.

Next, the operation of the present embodiment having such a configuration will be described.
First, the thermal transfer sheet body 2 including the supply core storage body 10 and the winding core 21 is prepared. In this case, one end of the belt-shaped thermal transfer sheet 5 is fixed to the supply core 11 and wound around the supply core 11 in a manufacturing factory or the like. Next, one end portion 14 of the supply core 11 wound up with the thermal transfer sheet 5 is inserted into a one-side opening bearing 31 formed in the case body 36 of the storage case 30, and the other end portion of the supply core 11 14 is arranged on the semicircular arc-shaped protrusion 32a of the case body 36 (state shown in FIG. 8). Thereafter, the fitting protrusion 38 a of the case lid 38 is fitted into the fitting hole 36 a of the case body 36, and the case lid 38 is attached to the case body 36.

  In this case, the other end region of the thermal transfer sheet 5 is made to come out of the storage case 30 through the slit 33 of the storage case 30. In this way, the supply core storage body 10 is prepared.

  Thereafter, the other end of the thermal transfer sheet 5 that appears outside from the storage case 30 through the slit 33 is fixed to the winding core 21, whereby the thermal transfer sheet body 2 is prepared.

  The thermal transfer sheet 5 of the thermal transfer sheet body 2 is stored in the supply core storage body 10. Therefore, it is possible to prevent the thermal transfer sheet 5 from being damaged from the outside.

  Further, by restricting the rotation of the supply core 11 in the supply core storage body 10, it is possible to prevent the winding of the thermal transfer sheet from being loosened during handling of the thermal transfer sheet body 2 and damaging the thermal transfer sheet 5. Can do. In this case, for example, the winding core 21 is temporarily fixed to the supply core housing 2 with a ring-shaped rubber or tape, or the thermal transfer sheet body 2 with the winding core 21 temporarily fixed in this way is further used as a wrapping paper. The thermal transfer sheet body 2 can be put on the distribution process simply by packaging, for example, by storing.

  In addition, as a method of restricting the rotation of the supply core 11 in the supply core storage body 10, the supply core 11 can be pressed from one side toward the other side. It is conceivable to fix to one side opening bearing 31 protruding from one side end face 30a. As a result, the supply core 11 is brought into contact with the other end face 30 b in the storage case 30, and is provided on the engaging portion 13 b provided on the other flange 13 of the supply core 11 and the other opening bearing 32 of the storage case 30. The engagement portion (not shown) is engaged, and the rotation of the supply core 11 is restricted.

  Next, a method for housing such a thermal transfer sheet body 2 in the thermal transfer sheet body cassette 40 will be described.

  First, the rod 71 disposed on the winding core holding part 61 of the thermal transfer sheet cassette 40 is removed.

  In this case, first, the rod 71 is swung with respect to the take-up core holding portion 61 from the state shown in FIG. 10A to the release position where the rod receiving through hole 75a of the one-side rod bearing 75 is released. Next, as shown in FIG. 10 (b), the one end 71a of the rod 71 projects from one side of the one-side rod bearing 75 toward the one side (from the right side to the left side in FIG. 10). ) Move it. As a result, the other end 71 b of the rod 71 comes out of the rod receiving hole 76 a of the other side rod bearing 76. Thereafter, as shown in FIG. 10 (c), the other end 71 b of the rod 71 is lifted, and the one end 71 a of the rod 71 is also pulled out of the rod receiving through hole 75 a of the one side rod bearing 75. Pull out. In this way, the rod 71 can be removed from the winding core holding part 61.

  Next, the supply core storage body 10 is mounted and held in the supply core storage body holding portion 51, and the winding core 21 is stored and held in the winding core storage portion 61.

  In this case, first, the other side opening bearing 32 protruding from the other end surface 30 b of the storage case 30 of the supply core storage body 10 is placed on the opening receiving portion 54 provided on the other side end surface 57 of the supply core storage body holding portion 51. While being inserted, the supply core storage body 10 is disposed above the supply core storage body holding portion 51 in a state along the supply core storage body holding portion 51. On the other hand, the other end 25 of the take-up core 21 is inserted into the opening bearing 64 provided on the other end face 67 of the take-up core holding part 61, and the take-up core 21 is inserted into the take-up core holding part 61. Is disposed above the take-up core holding part 61 in a state along the line.

  Thereafter, the end wall 41 is swung outward with respect to the supply core housing holding part 51 and the take-up core holding part 61. At this time, the engagement plates 42 a and 42 b of the end wall 41 are inserted into the engagement openings 53 a and 63 a of the support plates 53 and 63 of the supply core storage body holding portion 51 and the take-up core holding portion 61. Accordingly, as the end wall 41 swings outward, the support plates 53 and 63 also warp outward (FIG. 7).

  Thereby, the distance from the opening receiving part 54 of the other side end surface 57 of the supply core storage body holding | maintenance part 51 which received and hold | maintains the supply core storage body 10 to the control opening 53b of the support plate 53 becomes long (FIG. 7). At the same time, the distance from the opening bearing 64 on the other end surface 67 of the winding core holding portion 61 that receives and holds the winding core 21 to the restriction opening 63b of the support plate 63 becomes longer. For this reason, the supply core storage body 10 is stored in the supply core storage body holding part 51, and at the same time, the winding core 21 is stored in the winding core holding part 61.

  At this time, the storage case 30 of the supply core storage body 10 has an outer shape that engages with the inner surface shape of the supply core storage body holding portion 51 (FIG. 6). Deviation in the direction (the depth direction of the paper surface in FIG. 5) is restricted. Further, the winding core 21 is received by a release bearing 62 whose one end 24 is released upward, and displacement of the winding core 21 in the lateral direction (the depth direction of the paper surface in FIG. 4) is restricted. For this reason, the operator only needs to hold the central portion of the thermal transfer sheet cassette 40 with one hand and hold and swing the end wall 41 with the other hand. There is no need to adjust the position of the take-up core 21 in the supply core housing holding part 51 or the take-up core holding part 61.

  Thereafter, the hand is released from the end wall 41. Then, the warped support plates 53 and 63 function as leaf springs, and external force is eliminated. At the same time, the support plates 53 and 63 return to the positions shown in FIGS. 4 and 5 together with the end wall 41 engaged and connected. .

  Thereby, in the regulation opening 53b of the support plate 53 of the supply core storage body holding part 51 (as one side edge part of the supply core storage body 10 in this Embodiment), one of the storage cases 30 of the supply core storage body 10 The one-side opening bearing 31 protruding from the side end face 30a enters (FIG. 5), and the supply core storage body 10 is mounted and held on the supply core storage body holding portion 51. At the same time, one end 24 of the take-up core 21 enters the restriction opening 63b of the support plate 63 of the take-up core holding part 61 (FIG. 4), and the take-up core 21 is freely rotatable by the take-up core holding part 61. Attached and held.

  At this time, the supply core storage body 10 is supported circumferentially by the opening receiving portion 54 of the supply core storage body holding portion 51 on the other side, and is supported from below and laterally by the supply core storage body holding portion 51 on one side. At the same time, the support plate 53 is supported from above by the restriction opening 53b. Further, since the supply core storage body 10 is sandwiched between the support plate 53 of the supply core storage body holding part 51 and the other end surface 57, the supply core storage body 10 in the supply core storage body holding part 51 is provided. The movement in the longitudinal direction is restricted. Further, since the shape of the storage case 30 corresponds to the shape of the supply core storage body holding body 51 (FIG. 6), the rotation of the supply core storage body 10 in the supply core storage body holding body 51 is also performed. Be regulated. As a result, the supply core storage body 10 is securely fixed in the supply core storage body holding body 51 without rattling.

  On the other hand, the winding core 21 is supported circumferentially by the opening bearing 64 of the winding core holding portion 61 on the other side, and supported from below and from the side by the release bearing 62 on one side, and the restriction opening 63b of the support plate 63. Is supported from above. For this reason, the winding core 21 can be smoothly rotated without rattling.

  By the way, when the supply core storage body 10 is held by the supply core storage body holding portion 51, the contact portion 55 a of the pressing member 55 of the supply core storage body holding portion 51 protrudes from the restriction opening 53 b of the support plate 53. It abuts on one side end portion 14 of the supply core 11 disposed in the one side opening bearing 31 of the case 30. Then, due to the elastic force of the torsion spring 56, the contact portion 55a of the pressing member 55 presses the supply core 11 from one side to the other side in the storage case 30, and the other flange 13 of the supply core 11 is stored. It contacts the other side opening bearing 32 of the case 30. In this case, the engaging portion 13 b provided on the other flange 13 of the supply core 11 and the engaging portion (not shown) provided on the other opening bearing 32 of the storage case 30 engage with each other, and the storage case 30. The rotation of the supply core 11 inside is restricted. Thereby, winding slack of the thermal transfer sheet 5 wound around the supply core 11 can be prevented.

  On the other hand, when the take-up core 21 is held by the take-up core holding part 61, the pressing member 65 of the take-up core holding part 61 is one end of the take-up core 21 protruding from the restriction opening 63 b of the support plate 63. 24 abuts. Then, due to the elastic force of the torsion spring 66, the pressing member 55 presses the winding core 21 from one side toward the other side, and the other flange 23 of the winding core 21 is an open bearing of the winding core holding part 61. 64 abuts. In this case, the engaging portion 23b provided on the other flange 23 of the winding core 21 and the engaging portion (not shown) provided on the opening bearing 64 of the winding core holding portion 61 are engaged with each other. The rotation of the take-up core 21 in the take-up core holding part 61 is restricted.

  Next, as shown in FIG. 10, the thermal transfer sheet 5 is arranged so that the thermal transfer sheet 5 extending from the supply core housing 10 to the winding core 21 is disposed between the winding core holding part 61 and the rod 71. The rod 71 is attached to the winding core holding part 61 from above. In addition, the attachment method of the rod 71 to the winding core holding part 61 can be performed by the reverse procedure of the removal method from the winding core holding part 61 mentioned above.

  As described above, after removing the rod 71, the thermal transfer sheet body 2 is mounted on the thermal transfer sheet body cassette 40, and the rod 71 is attached again, whereby the thermal transfer sheet body 2 can be stored in the thermal transfer sheet pair cassette 40. Complete. At this time, the thermal transfer sheet body 2 is attached to the thermal transfer sheet pair cassette 40 only by positioning the other end of the thermal transfer sheet body 2 and then swinging the end wall 41 of the thermal transfer sheet pair cassette 40. Can be done by.

  Thus, the storing operation of the thermal transfer sheet body 2 is very simple and easy and can be performed quickly. Further, during this operation, the thermal transfer sheet 5 is exposed only at the end region that is not normally used for printing, and the other portions are stored in the storage case 30. Therefore, it is possible to prevent the thermal transfer sheet 2 from being damaged during the storage and mounting operation of the thermal transfer sheet body 2 in the thermal transfer sheet body cassette 40.

  Further, in spite of such simple and easy work, the supply core storage body 10 of the thermal transfer sheet body 2 is firmly and securely held by the supply core storage body holding portion 51 of the thermal transfer sheet body cassette 40, and the thermal transfer sheet. The winding core 21 of the body 2 is securely held rotatably by the winding core holding part 61 of the thermal transfer sheet pair cassette 40.

  The combined body 1 of the thermal transfer sheet body 2 and the thermal transfer sheet body cassette 40 thus obtained is then incorporated into a printer.

  When the thermal transfer sheet 5 is fed from the supply core housing 10 to the winding core 21 in the printer, a driving mechanism (not shown) is provided from the opening receiving portion 54 of the supply core housing holding portion 51 and the opening bearing 64 of the winding core holding portion 61. Inserted. With this drive mechanism, the supply core 11 and the take-up core 21 are moved from the other side (lower right side in FIG. 1) to one side (upper left side in FIG. 1) against the elastic force of the torsion springs 56 and 66. And is driven to rotate.

  In this case, both end portions 71 a and 71 b of the rod 71 are securely held by the rod receiving through hole 75 a of the rod bearing 75 on one side and the rod receiving hole 76 a of the rod bearing 76 on the other side. The rod 71 is disposed on the opposite side of the thermal transfer sheet 5 from the thermal head 5b (FIG. 10). Therefore, even when the thermal transfer sheet 5 is pressed by the thermal head 5b, the thermal transfer sheet 5 can be smoothly guided by the rotatable rod 71 without the rod 71 being detached from the take-up core holding part 61.

  Further, when the feeding of the thermal transfer sheet 5 is stopped, the drive mechanism is separated from the opening receiving portion 54 of the supply core storage body holding portion 51 and the opening bearing 64 of the winding core holding portion 61. In this case, the pressing members 55 and 65 respectively press the supply core 11 and the winding core 21 by the elastic force of the torsion springs 56 and 66 to move from one side to the other side. Thereby, as described above, the rotation of the supply core 11 and the take-up core 21 is restricted, and the winding of the thermal transfer sheet 5 can be prevented.

  When the thermal transfer sheet 5 is used up, the thermal transfer sheet body 2 is removed from the thermal transfer sheet body cassette 40, and a new thermal transfer sheet body 2 is stored and mounted on the thermal transfer sheet body cassette 40 in the manner described above.

  The method of removing the thermal transfer sheet body 2 from the thermal transfer sheet body cassette 40 is performed in the reverse procedure of the above-described storage method. That is, the rod 71 is first removed and then the thermal transfer sheet body 2 is removed from the thermal transfer sheet pair cassette 40 to complete the process. At this time, the thermal transfer sheet body 2 is detached from the thermal transfer sheet body cassette 40 by swinging the end wall 41 of the thermal transfer sheet body cassette 40 and lifting the thermal transfer sheet body 2 or by removing the end wall 41. In a state of being swung, the thermal transfer sheet body cassette 40 is turned upside down and the thermal transfer sheet body 2 is dropped by gravity.

  As described above, since the removal operation of the thermal transfer sheet body 2 can be performed very simply and easily, the replacement operation of the thermal transfer sheet body 2 can be performed simply and easily and quickly.

  As described above, according to the present embodiment, the rod 71 is removed from the take-up core holding portion 61, and the supply core storage body 10 and the take-up core 21 of the thermal transfer sheet body 2 are stored in the supply core storage of the thermal transfer sheet body cassette 40. The body holding part 51 and the take-up core holding part are respectively attached and held, and the rod 71 is attached again, whereby the storage of the thermal transfer sheet body 2 in the thermal transfer sheet body cassette 40 is completed.

  In this case, the supply core storage body 10 is attached to the supply core storage body holding portion 51 in a state where the other opening bearing 32 of the storage case 30 is inserted into the opening receiving portion 54 of the supply core storage body holding portion 51. This is completed by swinging the end wall 41 of the sheet cassette 40. Similarly, the winding core 21 is attached to the winding core holding portion 61 in a state where the other end 25 of the winding core 21 is inserted into the opening bearing 64 of the winding core holding portion 61. This is completed by swinging the end wall 41 of the cassette 40.

  Thus, the heat transfer sheet body 2 can be accommodated in the thermal transfer sheet body cassette 40 by a simple and easy operation, and the operation time can be shortened. Further, the thermal transfer sheet body 2 housed and mounted in such a simple and easy operation in a short time is securely held in the thermal transfer sheet body cassette 40 without rattling.

  Further, the thermal transfer sheet 5 of the thermal transfer sheet body 2 is stored and protected in the storage case 30 except for an end region that is not used for printing. For this reason, during handling of all the thermal transfer sheet bodies 2 including when stored in the thermal transfer sheet body cassette 40, an operator touches the thermal transfer sheet 5 (used for printing) to damage the thermal transfer sheet 5. This can be prevented.

  Further, the supply core storage body 10 and the winding core 21 of the thermal transfer sheet body 2 are not separately mounted on the thermal transfer sheet body cassette 40 by swinging the end wall 41 of the thermal transfer sheet body cassette 40. It is installed at the same time. Therefore, the thermal transfer sheet 5 that is fixed and wound around the supply core 11 and the take-up core 21 and that connects the supply core 11 and the take-up core 21 is housed in the thermal transfer sheet cassette 40 without being damaged. Can do. Further, compared with the case where the supply core 11 and the winding core 21 of the thermal transfer sheet body 2 are separately mounted on the thermal transfer sheet body cassette 40, the work time required for the storage mounting work can be shortened by storing and mounting simultaneously. Can do.

  Furthermore, as described above, since the thermal transfer sheet 5 of the thermal transfer sheet body 2 is stored in the storage case 30, the thermal transfer sheet 5 is not damaged during handling of the thermal transfer sheet body 2, and the thermal transfer sheet Storage and removal of the sheet body 5 from the thermal transfer sheet body cassette 40 is easy. Therefore, it is also possible to ship and distribute as the thermal transfer sheet body 2 and replace the thermal transfer sheet body 2 of the combination 1 by a general user. As a result, the thermal transfer sheet cassette 40 can be reused without being disposable, and resources can be saved. Moreover, the replacement cost of the thermal transfer sheet 5 per time can be reduced. In this case, the thermal transfer sheet 5 is not connected to the winding core 21, that is, the thermal transfer including the supply core storage body 10 and the separate winding core 21 not connected to the supply core storage body 10. The sheet body 2 may be distributed.

  In addition, when circulating as the thermal transfer sheet body 2 instead of the combination body 1, the rotation of the supply core 11 is regulated in the storage case 30 so that the thermal transfer sheet 5 does not sag in the storage case 30. It is preferable to make it. This is to prevent the thermal transfer sheet 5 from being damaged by the loosening of the thermal transfer sheet 5.

  As such a method, for example, a cap or the like capable of pressing the supply core 11 from one side toward the other side is applied to the one side opening bearing 31 protruding from the one side end face 30a of the storage case 10. It may be fixed. In this case, the supply core 11 is brought into contact with the other opening bearing 32 in the storage case 30, and is provided on the engaging portion 13 b provided on the other flange 13 of the supply core 11 and the other opening bearing 32 of the storage case 30. The engagement portion (not shown) is engaged, and the rotation of the supply core 11 is restricted. Thereby, the winding core 21 is temporarily fixed to the supply core storage body 2 with a ring-shaped rubber or tape, or the thermal transfer sheet body 2 with the winding core 21 temporarily fixed is further stored in the wrapping paper. The thermal transfer sheet body 2 can be placed in the distribution process simply by packaging.

  In the present embodiment, the example in which the thermal transfer sheet 5 is handled as the thermal transfer sheet body 2 has been described. However, the present invention is not limited to this, and the supply core storage body 10 may be handled. That is, it is also possible to ship and distribute as the supply core storage body 10, to dispose only the supply core storage body 10, and to reuse the winding core 21 together with the thermal transfer sheet body cassette 40. By doing so, resources can be further saved and the replacement cost of the thermal transfer sheet 5 per time can be further reduced.

  In this case, each time the supply core storage body 10 is replaced, the end portion of the thermal transfer sheet 5 is fixed (connected) to the winding core, and the thermal transfer sheet body 2 including the supply core storage body 10 and the winding core is obtained. Must be formed. After the thermal transfer sheet body 2 is formed, it can be handled in the same manner as in the embodiment described above.

  The fixing (coupling) of the end portion of the thermal transfer sheet 5 to the winding core 21 may be performed after the supply core storage body 10 is mounted on the supply core storage body holding portion 51 of the thermal transfer sheet body cassette 40. . In this case, the end portion of the thermal transfer sheet 5 can be fixed (connected) to the winding core 21 by passing between the winding core holding portion 61 and the rod 71 described above. It is possible to save the trouble of removing from the winding core holding part 61 each time.

  Further, when the supply core storage body 10 is circulated, the supply core 11 of the supply core 11 is stored in the storage case 30 so that the thermal transfer sheet 5 is not wound and loosened, as in the case where the thermal transfer sheet body 2 is circulated. It is preferable to restrict the rotation. Furthermore, it is also preferable that only the end region is taken out from the slit 33 of the storage case 30 and fixed to the storage case 30 with a tape or the like. Furthermore, it is more preferable that the end of the thermal transfer sheet 5 on the side fixed (connected) to the winding core 21 is tapered and reinforced to increase the rigidity. In this case, it becomes easy to guide this end portion between the winding core holding portion 61 and the rod 71.

  Further, in the present embodiment, an example is shown in which the thermal transfer sheet body 2 is housed in the thermal transfer sheet body cassette 40 and then the thermal transfer sheet body cassette 40 is incorporated in the printer. However, the present invention is not limited to this. The body cassette 40 may be formed integrally with the printer, and the thermal transfer sheet body 2 may be stored and mounted directly in the printer. That is, the supply core storage body holding part 51, the winding core holding part 61, and the end wall 41 may be provided directly in the printer.
