This tape cartridge has an outer shell made up of a cartridge case having a two-divided structure in which a printing tape and an ink ribbon used for printing are detachably accommodated, so that the cartridge case can be reused. It is configured to be separable without damage. The tape cartridge disassembly jig is a dedicated jig for disassembling the tape cartridge. In the following description, first, a printing apparatus that accommodates a tape cartridge will be briefly described.

  1 and 2 are an overall perspective view and an overall perspective view of a printing apparatus according to an embodiment of the present invention, respectively. As shown in both drawings, the printing apparatus 1 has an outer shell formed by an apparatus case 2, a keyboard 3 serving as a character input means on the upper surface of the front of the apparatus case 2, and an open / close attached to the upper surface of the rear. A freely openable lid 6, a display 4 that displays information such as characters so as to face the window on the right side of the openable lid 6, a discharge port 10 that is formed on the left side surface of the device case 2 and communicates with the outside of the device, and the device The left portion of the case 2 includes a mounting portion 5 that detachably stores the tape cartridge 20. The printing apparatus 1 prints a desired character or figure on a printing tape T via a tape cartridge 20 and cuts a printed portion of the tape into a predetermined length to produce a label. .

  When the user uses the printing apparatus 1, first, the opening / closing lid 6 is opened, and the head opening 23 formed through the tape cartridge 20 is guided to the head unit 7 of the mounting portion 5, so that the tape cartridge 20 Is mounted on the mounting portion 5 and the open / close lid 6 is closed. Next, while confirming the input / edit result on the display 4, print information such as a desired character is input by the keyboard 3, and printing is instructed on the print tape T supplied by the tape cartridge 20. Printing on the printing tape T is performed by the internal mechanism 8 and the thermal head 11 of the head unit 7. The printed portion of the printing tape T on which printing has been performed is sent out from the discharge port 10 to the outside of the apparatus case 2 as needed, while the printed portion of the ink ribbon R on which printing has been performed is wound up in the tape cartridge 20. Be contained. When the printing is completed, the user presses a cut button (not shown) to cut the print tape T to a desired length and create a desired label.

  Next, the tape cartridge will be described in detail based on FIG. 3, FIG. 4, and FIG. An outer shell of the tape cartridge 20 is formed by a cartridge case 21 composed of an upper case 40 and a lower case 50, and the inside of the cartridge case 21 is a narrow tape housing portion 30 and a wide ribbon housing portion 31. It consists of and.

  A tape assembly 32 including a printing tape T and a tape core 35 around which the printing tape T is wound is accommodated in the tape accommodation unit 30. The ribbon container 31 accommodates a ribbon assembly 33 including an ink ribbon R, a feeding core 36 for feeding out the ink ribbon R, and a winding core 37 for winding up the ink ribbon R, and a platen rubber is wound thereon. A hollow cylindrical platen 34 is accommodated. The tape core 35, the feeding core 36, the take-up core 37, and the platen 34 are rotatably supported by shaft protrusions and fitting holes formed in the upper case 40 and the lower case 50, and are divided as shown in FIG. When the top and bottom are reversed, the housing parts (34, 35, 36, 37) are free to fall off the shaft protrusions and fitting holes.

  The lower case 50 is formed with a lower head opening 53 facing the thermal head 11, and the upper case 40 corresponds to the lower head opening 53. 43 is formed. Further, a guide wall 59 having a substantially “C” shape in a plan view is formed on the edge of the lower head opening 53 so as to protrude.

  The printing tape T wound around the tape core 35 is unwound from the tape core 35 and reaches the platen 34. Further, the ink ribbon R sent from the feeding core 36 circulates along the outer peripheral surface of the guide wall 59 through the platen 34 (thermal head 11) and is wound around the winding core 37. As a result, the ink ribbon R and the printing tape T overlap at the position of the platen 34, and the ink on the ink ribbon R is peeled off in a letter shape and transferred to the printing tape T. The printed portion of the printing tape T on which printing has been performed passes through the feed slit 39 of the cartridge case 21 and is sent out from the discharge port 10 of the printing apparatus 1 to the outside of the apparatus case 2 as needed.

  Next, the joining form of the cartridge case 21 will be described in detail. In the cartridge case 21 of the present embodiment, the upper case 40 and the lower case 50 are constituted by a two-part structure, and the upper case 40 and the lower case 50 are joined so that their joint end faces are abutted with each other. That is, the upper case 40 is integrally formed with the top wall portion 41 and the upper peripheral wall portion 42 (joint portion), and the lower case 50 is integrally formed with the bottom wall portion 51 and the lower peripheral wall portion 52 (joint portion). Has been. The upper case 40 and the lower case 50 are joined so that the end surface of the upper peripheral wall portion 42 and the end surface of the lower peripheral wall portion 52 abut each other.

  The upper case 40 is formed with three engagement pins 45, six press-fit pins 44, and two hooks 46, and the lower case 50 has three engagement holes 55 corresponding thereto. And six through holes 54 and two hook receiving portions 56 are formed. That is, each engagement pin 45 engages with the corresponding engagement hole 55 to position the upper case 40 and the lower case 50, and each press-fit pin 44 press-fits into the corresponding through-hole 54 to The lower case 50 is joined, the hooks 46 are engaged with the corresponding hook receiving portions 56, and the upper case 40 and the lower case 50 are joined with impact resistance.

  Of the three engagement pins 45, two engagement pins 45 are disposed on the left and right of the upper case 40, and the other one is disposed on the edge of the upper head opening 43. The wall portion 41 is formed integrally and protruding. In addition, two engagement holes 55 are formed corresponding to the engagement pins 45, two on the lower peripheral wall portion 52 of the lower case 50 and one on the guide wall 59. The engaging pin 45 is formed in a substantially cylindrical shape, and its tip end portion is formed in a tapered shape so as to guide the insertion into the engaging hole 55. Further, the engagement hole 55 has a depth corresponding to the length of the engagement pin 45 and is formed with a tightening allowance with the engagement pin 45 of 0 so that the engagement pin 45 can be engaged easily. It has become.

  The six press-fit pins 44 protrude so that five on the end surface of the upper peripheral wall portion 42 of the upper case 40 and one on the edge of the upper head opening 43 are dispersed, and are integrally formed with the upper case 40. ing. The six through-holes 54 are formed integrally with the lower case 50 in correspondence with the press-fit pins 44, with five on the end surface of the lower peripheral wall portion 52 of the lower case 50 and one on the guide wall 59. Yes. More specifically, the press-fit pins 44 and the through holes 54 are a pair of right and left at the rear portion of the tape housing portion 30, two at the rear portion and the front portion of the right portion of the ribbon housing portion 31, and the ribbon housing portion. One is arranged in the middle part of 31 and one is arranged in the left part of the ribbon accommodating part 31.

  As with the engagement pin 45, the press-fit pin 44 is formed in a substantially cylindrical shape, and its tip is formed in a tapered shape. However, the press-fit pin 44 has a larger diameter than the engagement pin 45. Further, the through hole 54 passes through the lower case 50 in the axial direction, and is opened on the back side of the bottom wall portion 51. Therefore, the through hole 54 penetrates the lower peripheral wall portion 52 of the lower case 50 in the vertical direction. Further, the axial direction of each press-fit pin 44 and the axial direction of each through hole 54 coincide.

  The diameter of the press-fit pin 44 is slightly larger than the diameter of the through hole 54, and the press-fit pin 44 and the through hole 54 are formed with a tightening margin of about 0.08 mm ± 0.02. Therefore, when the press-fit pin 44 is fitted into the through-hole 54, the press-fit pin 44 is inserted into the through-hole while the upper and lower cases 40, 50 are positioned with the engagement pin 45 aligned with the position of the engagement hole 55. The press-fit pin 44 is fitted into the through-hole 54.

  As a result, the press-fit pin 44 is slightly deformed and tightly adheres to the through-hole 54 to strongly fasten the upper case 40 and the lower case 50, and the upper case 40 and the lower case 50 are separated by a drop impact. It becomes a state that does not. In the cartridge case 21, when the press-fit pin 44 is press-fitted into the through hole 54, the tip of the press-fit pin 44 extending from the upper case 40 passes through when viewed from the back side of the bottom wall portion 51 of the lower case 50. It is joined in a state of stopping in the middle of the hole 54.

  On the other hand, in the cartridge case 21, the front end portion of the press-fit pin 44 is pushed through the through-hole 54 from the back side of the bottom wall portion 51 of the lower case 50, whereby the tightening force between the press-fit pin 44 and the through-hole 54 is released. It has become so. That is, by pressing the press-fit pin 44 through the through hole 54 from the direction opposite to the press-fit direction, the fit between the press-fit pin 44 and the through hole 54 is loosened, and the cartridge case 21 is separated into the upper case 40 and the lower case 50. It has a configuration.

  The two hooks 46 and the hook receiving portion 56 are disposed apart from the right portion and the left portion of the ribbon accommodating portion 31 in consideration of balance. The hook 46 is formed integrally with the upper case 40 and protruding from the end surface of the upper peripheral wall portion 42, and the hook receiving portion 56 is formed by cutting out a part of the lower peripheral wall portion 52 of the lower case 50. . As a result, the upper and lower cases 40 and 50 are prevented from floating in the ribbon accommodating portion 31 which causes the ink ribbon R to be wrinkled or kinked. Hereinafter, the hook 46, the hook receiving portion 56, and the hook detachment prevention wall 70 provided adjacent to the hook receiving portion 56 will be described in order with reference to FIGS.

  As shown in FIG. 6, the hook 46 includes a hook spring portion 60 having a spring property protruding from the end surface of the upper peripheral wall portion 42 of the upper case 40, and an outward hook engaging portion formed at the distal end portion of the hook spring portion 60. 61 is integrally formed. The hook engaging portion 61 has a hook engaging surface 62 that is engaged with and directly engaged with the hook receiving portion 56, and a hook inclined surface 63 that guides the engaging operation. The hook 46 bends against the spring property of the hook spring portion 60 by an external force, and is sandwiched between the hook receiving portion 56 and the hook detachment prevention wall 70.

  As shown in FIGS. 7 to 10, the hook receiving portion 56 is formed by cutting the lower peripheral wall portion 52 of the lower case 50 into a square shape with a substantially hook width to the lower end, leaving the upper end portion in a bridge shape. On the lower end surface of the bridge-shaped portion, a receiving portion hooking surface 72 (see FIG. 9) for locking the hook 46 is formed. Further, as shown in FIG. 8, the hook receiving portion 56 has a locking guide surface 73 formed by chamfering the upper end surface of the bridge-shaped portion (the end surface of the lower peripheral wall portion 52) to a substantially hook width.

  When the hook 46 comes into contact with the hook receiving portion 56 in accordance with the press-fitting operation into the lower case 50 of the upper case 40, the hook inclined surface 63 of the hook locking portion 61 is guided by the locking guide surface 73 of the hook receiving portion 56. The hook engaging surface 62 and the receiving portion engaging surface 72 perpendicular to the axial direction of the through hole 54 are in direct contact with each other, and the hook 46 is engaged with the hook receiving portion 56. Although details will be described later, in the tape cartridge disassembling jig 80 according to the embodiment, a release force is applied to the hook locking portion 61 of the hook 46. At this time, a piece of the hook removing piece 123 described later is used. The inclined surface 153 and the hook inclined surface 63 are related to each other so that a component force in the removal direction acts on the hook 46.

  The hook detachment prevention wall 70 is erected integrally with the lower case 50 with a slight gap in which the hook 46 is inserted on the back side of the hook receiving portion 56, and the right and left portions of the ribbon accommodating portion 31. Two (70a, 70b) are arranged in total. As shown in FIGS. 8 and 10, the hook detachment prevention wall 70 is cantilevered from the bottom wall portion 51 of the lower case 50 on the back side, which is the unlocking side of the hook 46, and has the same height as the lower peripheral wall portion 52. Is erected. The hook detachment prevention wall 70 is thin and thus has a spring property. The slight gap with the hook receiving portion 56 causes the hook 46 of the upper case 40 to be connected to the hook receiving portion 56 of the lower case 50. It is dimensioned so that the hook locking portion 61 is barely inserted when locked, and is slightly smaller than the size of the hook locking portion 61 of the hook 46.

  11 is a cross-sectional view taken along line AA in FIG. The hook 46 of the upper case 40 is sandwiched between the hook receiving portion 56 of the lower case 50 and the hook removal prevention wall 70 (70b). That is, the upper case 40 and the lower case 50 are synchronized with the engagement operation of the engagement pin 45 engaged with the engagement hole 55 and the press-fitting operation of the press-fit pin 44 press-fitted into the through hole 54. The hook 46 is inserted into a gap between the hook receiving portion 56 of the lower case 50 and the hook detachment preventing wall 70 and locked to the hook receiving portion 56.

  At this time, the hook 46 is guided to the hook receiving portion 56 by the hook inclined surface 63 while the hook detaching prevention wall 70 is bent to the back side by the hook engaging portion 61, and the hook receiving portion 56 is detached from the hook receiving portion 56. The hook engaging surface 62 and the receiving portion engaging surface 72 are brought into contact with each other and engaged with each other, and the hook spring portion 60 is connected to the hook receiving portion 56 and the hook disengagement preventing wall 70. It will be in the state pinched by. Therefore, even if the hook 46 bends toward the hook detachment prevention wall 70 due to a strong drop impact or the like, the hook detachment prevention wall 70 in the free state prevents further deflection, so that the hook 46 is engaged with the hook receiving portion 56 due to the strong drop impact. It is prevented from being released.

  Therefore, the upper case 40 and the lower case 50 of the cartridge case 21 are strongly joined and held in the tape cartridge 20 by press-fitting by the press-fit pins 44 and locking by the hooks 46. In this case, the cartridge case 21 is configured so that the press-fit pin 44 and the hook 46 are not damaged in the separation process so that the cartridge case 21 can be separated at least 10 times. Further, the cartridge case 21 is configured not to be separated into the upper case 40 and the lower case 50 against a drop impact from a height of about 75 cm (desk height).

  On the other hand, the hook 46 held between the hook receiving portion 56 and the hook detachment prevention wall 70 presses the hook engaging portion 61 against the hook detachment prevention wall 70, so that the hook spring portion 60 prevents the hook detachment. As the wall 70 is biased and deflected, the hook detachment prevention wall 70 is also urged and deflected in the back direction, and a slight gap is formed between the hook receiving portion 56 and the hook detachment prevention wall 70. Then, when the hook locking portion 61 passes between the hook receiving portion 56 and the hook detachment preventing wall 70, the locking by the hook 46 with respect to the hook receiving portion 56 is completely released.

  As shown in FIG. 10, the hook disengagement prevention wall 70 b located at the left part of the ribbon accommodating portion 31 has a wall surface on the side of the lower head opening 53 formed in a wave shape with respect to the lower head opening 53. As a result, the ink ribbon R that passes between the left hook release prevention wall 70b and the lower head opening 53 and is taken up by the ribbon take-up core 37 has the hook release prevention wall having the corrugated wall surface. The contact area with 70b becomes small, and the sticking with the wall surface of the hook removal prevention wall 70b with respect to long-term storage is prevented. Further, the left hook disengagement prevention wall 70 b prevents the ink ribbon R from coming into contact with the hook 46. That is, the left-side hook disengagement prevention wall 70b prevents the ink ribbon R from coming into contact with the hook 46 when it is wound and accommodated, and also releases the hook 46 from the hook receiving portion 56. Thus, the hook 46 is prevented from being bent and contacting the back side thereof.

  Instead of forming the hook 46 in the upper case 40 and the hook receiving portion 56 in the lower case 50, the hook 46 is formed in the lower case 50 and the hook receiving portion 56 is formed in the upper case 40. And the lower case 50 may be locked. Further, instead of forming the hook detachment prevention wall 70 in the lower case 50, it may be formed in the upper case 40, and the hook 46 and the hook detachment prevention wall 70 may be formed in the same case. Furthermore, the number of press-fit pins 44 may be an arbitrary number, and is not limited to six as in the present embodiment.

  Further, as shown in FIGS. 3 and 4, the cartridge case 21 has a label tape groove 38 formed in the tape housing portion 30. The label tape groove 38 is formed in the upper peripheral wall portion 42 and the lower peripheral wall portion 52, and is formed across the surface of the top wall portion 41 of the upper case 40. As shown in FIG. 3, the tape cartridge 20 has a peelable label tape 22 attached to the label tape groove 38, and upper and lower cases 40, 50 are sealed by the tape housing portion 30, so that the upper case 40 And the lower case 50 are joined. Further, by providing the label tape groove 38, it is possible to eliminate the unevenness of the outline of the cartridge case 21 that occurs when the label tape 22 is attached to the cartridge case 21, so that the tape cartridge 20 can be removed from the printing apparatus 1. The label tape 22 is prevented from being easily peeled off depending on the frequency or the like.

  Furthermore, the cartridge case 21 is formed in a shape necessary when a tape cartridge disassembly jig 80 described later is used. As shown in FIGS. 3 and 4, the lower peripheral wall portion 52 of the lower case 50 of the cartridge case 21 has four hook portions whose contours are relatively convex with respect to the upper peripheral wall portion 42 of the upper case 40. 49 is formed in a distributed manner in the front, rear, left and right. Specifically, the hook portion 49 includes a concave portion 47 of the upper case 40 and a jig receiving portion 57 of the lower case 50.

  The concave portion 47 of the upper case 40 is formed so as to be recessed from the lower end (the top wall portion 41) of the upper peripheral wall portion 42 of the upper case 40 in the axial direction of the press-fit pin 44. In the jig receiving portion 57 of the lower case 50, the end surface of the lower peripheral wall portion 52 is formed in a thick shape corresponding to the concave portion 47 of the upper case 40 (see FIG. 10). Therefore, since the cartridge case 21 itself does not have a convex portion, the hooking portion 49 does not interfere with the apparatus side when being attached to or detached from the mounting portion 5 of the printing apparatus 1. Then, the tape cartridge 20 is set on the tape cartridge disassembly jig 80 via the hook portion 49 with the cartridge case 21 turned upside down, that is, with the upper case 40 turned downward.

  Next, a tape cartridge disassembly jig 80 for disassembling the tape cartridge 20 will be described. The tape cartridge disassembling jig 80 pushes the press-fit pin 44 from the through hole 54 without whitening / damaging the press-fit pin 44 press-fitted into the cartridge case 21, and simultaneously with the press-fit release operation, The hook 46 is unlocked from the receiving portion 56, and the cartridge case 21 is separated into the upper case 40 and the lower case 50.

  As shown in FIGS. 12, 13, and 14, the tape cartridge disassembling jig 80 is attached to the hand press 90 (moving means) that applies a force for disassembling the tape cartridge 20 and attached to the hand press 90. The jig body 100 is configured to cause the applied force to act on the tape cartridge 20 and disassemble it.

  The hand press 90 includes a plate-shaped pedestal 91, a support frame 92 erected on the pedestal 91, a guide arm 93 projecting horizontally from the support frame 92 toward the front of the pedestal 91, and a height position of the guide arm 93. An adjustment bolt 94 for adjusting the pressure, a pressure head 95 which is inserted through the insertion hole 81 of the guide arm 93 and is movable in the vertical direction, an operation lever 96 for moving the pressure head 95 in the vertical direction, and an operation lever 96 The toggle link 97 is connected to the pressure head 95. The hand press 90 amplifies a slight force by the operation lever 96 by a toggle link 97 (toggle mechanism), and outputs a very large downward force to the pressure head 95.

  The toggle link 97 has an upper portion connected to the upper portion of the pressure head 95 via the link support portion 85, and a lower portion connected to the lower portion of the operation lever 96 having the grip 98. The operation lever 96 is rotated about the lever support portion 99 as a rotation axis, and moves the toggle link 97 up and down and moves the pressure head 95 up and down via the toggle link 97. The downward movement of the pressure head 95 is caused by the operation lever 96, but the upward movement is caused by the spring force of the coil spring 84 wound around the pressure head 95.

  The insertion hole 81 of the guide arm 93 is formed in a square cross section by a concave groove formed in the guide arm 93 and a cover plate 82 provided so as to close the opening of the concave groove. The pressure head 95 is formed in a square cross section corresponding to the insertion hole 81, and a mounting hole 83 for mounting the movable portion 101 of the jig main body 100 is formed in the lower end portion.

  In the hand press 90 formed in this way, the movable portion 101 of the jig main body 100 is set at the lower end portion of the pressure head 95, and the fixed portion 102 of the jig main body 100 is set on the pedestal 91. Then, the movable portion 101 of the jig main body 100 is lowered by the downward rotation operation of the operation lever 96, and at the same time, a large downward force is applied to the tape cartridge 20 set on the fixed portion 102. The cartridge case 21 is separated into the upper case 40 and the lower case 50 by applying a force in a direction perpendicular to the lower direction (hereinafter referred to as a lateral direction).

  The jig body 100 includes a movable portion 101 that is fixed to the hand press 90 and moves up and down, and a fixed portion 102 that receives the movable portion 101. As shown in FIGS. 12 and 13, the jig main body 100 includes an extruding means 110 on the movable portion 101 side set on the pressure head 95 of the hand press 90 and a fixed portion set on the base 91 of the hand press 90. It comprises a setting means 111 on the 102 side and a hook releasing means 112 on the movable portion 101 side which is located below the pushing means 110 and releases the locking of the tape cartridge 20 by the hook 46.

  The jig body 100 holds only the lower case 50 by setting the means 111 so that the back side of the bottom wall portion 51 of the lower case 50 of the tape cartridge 20 faces the pushing means 110 with the upper case 40 facing downward.

The connection support block portion 143 is formed in a shape that matches the outer shape of the rear portion of the tape cartridge 20, and two hook portions 148 that hold the ribbon housing portion 31 side of the tape cartridge 20 are formed.

  Each hook portion 148 is formed in a convex shape corresponding to each concave portion 47 of the upper case 40 of the tape cartridge 20 and allows insertion into the drop-off opening 145 of the upper case 40 from above. That is, the hooking portion 148 allows the upper case 40 to be inserted into the drop-off opening 145, and its upper surface abuts against the jig receiving portion 57 of the lower case 50 to hold only the lower case 50 in a non-drop-off state. It is like that. Therefore, the tape cartridge 20 is restricted from moving back and forth and left and right by the positioning block 120, and the holding block 121 allows the upper case 40 to be moved up and down, and the setting means 111 in a state where only the lower case 50 is held. To be set.

  As shown in FIGS. 12 and 13, the base plate 122 is bolted to the pedestal 91 while being seated on the upper surface of the pedestal 91 of the hand press 90, and supports the holding block 121 and the positioning block 120 in order on the upper surface. Yes. The first and second support block portions 141 and 142 and the connection support block portion 143 of the holding block 121 are individually fixed to the base plate 122 with hexagon socket bolts 126. The support block portions 141, 142, and 143 of the holding block 121 are formed with hollow holes through which the hexagon socket bolts 126 are inserted, and the support block portions 141, 142, and 143 have a minute gap therebetween. The above-described drop-off opening 145 is formed oppositely.

  The diameter of the fool hole is sufficiently large compared to the diameter of the hexagon socket head bolt 126, and the positions of the support block portions 141, 142, and 143 can be adjusted within a minute interval. It is configured. As a result, manufacturing errors (for each lot) of the tape cartridge 20 (cartridge case 21) are absorbed, and the tape cartridge 20 can be appropriately set in the holding block 121.

  Similarly to the relationship between the holding block 121 and the base plate 122, the guide block portions 131, 132, 133, and 134 of the positioning block 120 are individually fixed to the holding block 121. That is, the first guide block portion 131 and the second guide block portion 132 are provided to the first support block portion 141 and the second support block portion 142, and the third guide block portion 133 is provided to the connection support block portion 143. The block portion 134 is individually fixed to one end of the first support block portion 141 and one end of the second support block portion 142 with hexagon socket head cap screws 126.

  The guide block portions 131, 132, 133, and 134 of the positioning block 120 are formed with hollow holes through which the hexagon socket bolts 126 are inserted, and the guide block portions 131, 132, 133, and 134 are spaced from each other by a minute gap. The above-mentioned fitting opening 135 is formed facing each other. That is, the first guide block part 131 and the second guide block part 132 sandwiched between the third guide block part 133 and the fourth guide block part 134 are the third guide block part 133 and the fourth guide block part 134. It is formed slightly smaller than the opposite distance between them. The diameter of the fool hole is sufficiently large compared to the diameter of the hexagon socket head bolt 126, and the guide block portions 131, 132, 133, and 134 are positioned within a minute distance between each other. It is configured to be adjustable.

  As a result, manufacturing errors (for each lot) of the tape cartridge 20 (cartridge case 21) are absorbed, and the tape cartridge 20 can be appropriately set in the positioning block 120. Therefore, the tape cartridge 20 can be reliably set on the setting means 111.

  Two hook release means 112 are provided corresponding to the two hooks 46 of the tape cartridge 20. As shown in FIG. 13, the hook releasing means 112 includes a hook removing piece 123 attached to the positioning block 120 and a piece actuating member 124 fixed to the lower portion of the pushing means 110, and the hook removing piece 123 and the piece actuating member are formed. The engagement with the hook 46 of the tape cartridge 20 is released by the interaction with 124.

  The hook removing piece 123 is engaged with a piece main body 150 formed in a prismatic shape, a wedge-shaped wedge-shaped portion 151 formed at the tip of the piece main body 150, and a piece operating member 124 provided at the tail end portion of the piece main body 150. And a guide pin 152 (see FIGS. 17 and 18). The guide pin 152 horizontally penetrates the tail end portion of the piece main body 150, and both protruding portions protruding from the piece main body 150 are engaged with cam slits 163 (inclined cams) described later. The hook removal piece 123 presses the hook 46 of the tape cartridge 20 set on the setting means 111 to release the latch and releases the sliding groove 136 between the release position and the retracted position retracted backward from the release position. It is attached to freely move forward and backward.

  As shown in FIGS. 12, 13, and 17, each piece actuating member 124 is attached downward to the lower portion of the extrusion plate 116, and is integrally formed in an L shape by a fixing member 160 and a member main body 161 that hangs down from the fixing member 160. Is formed. The member main body 161 has a guide groove 162 that sandwiches the hook removal piece 123 in the front and rear intermediate portion so as to be slidable in the vertical direction, and intersects the guide groove 162 in a cross-sectional shape in the left and right intermediate portion. A cam slit 163 for advancing and retracting the hook removing piece 123 is formed.

  The cam slit 163 extends in the vertical direction from the upper side to the lower side, inclines at an intermediate position thereof, and further extends to the lower end. The cam slit 163 is engaged with the guide pin 152 of the hook removing piece 123. That is, the cam slit 163 of the piece actuating member 124 and the guide pin 152 of the hook removing piece 123 change the operation of the cam mechanism 129 that converts the vertical movement of the piece actuating member 124 into the horizontal movement of the piece 123. The mechanism is configured.

  As represented by the phantom line in FIG. 12, the push-out means 110 is lowered by the downward rotation operation of the operation lever 96, and the piece actuating member 124 connected to the push-out means 110 is lowered, thereby causing a cam action. The hook removing piece 123 moves horizontally inward in the horizontal direction, the wedge-shaped portion 151 abuts on the hook engaging portion 61 of the tape cartridge 20 held by the setting means 111, and the hook 46 is engaged with the hook receiving portion 56. The stop state can be released.

  The cam curve in the cam slit 163 of the piece actuating member 124 is inclined so that the hook removal piece 123 moves more inward in the lateral direction than necessary and presses the hook 46 more than necessary to damage the hook 46. The balance between the amount and the force pressing the hook 46 is maintained. More specifically, when the push-out plate 116 is lowered, the push-out pin 115 and the piece actuating member 124 are horizontally lowered, and the hook removing piece 123 slides in the sliding groove 136 inward in the lateral direction according to the cam curve. The hook removing piece 123 comes into contact with the hook engaging portion 61 and presses the hook 46 in the back direction (lateral direction) to widen the gap between the hook receiving portion 56 and the hook disengagement prevention wall 70, and to the hook receiving portion 56. The hook 46 can be unlocked.

  Then, when each push pin 115 presses each press-fit pin 44 press-fitted into each through-hole 54 at the same time, the piece actuating member 124 is also lowered in synchronization with each push-down pin 115 further lowered. However, at this time, the cam slit 163 of the piece actuating member 124 is moved from its intermediate position (the end position of the cam curve) so that the hook removing piece 123 does not slide further and presses the hook locking portion 61 further. It extends vertically to the top.

  FIG. 18 is a diagram showing the relationship between the locking by the hook 46 and the hook removing piece 123. The hook removing piece 123 is moved inward in the horizontal direction by the cam mechanism 129, and the wedge-shaped portion 151 of the hook removing piece 123 presses the hook engaging portion 61. That is, the piece inclined surface 153 of the wedge-shaped portion 151 and the hook inclined surface 63 of the hook locking portion 61 are involved, and as shown in FIG. Works. That is, in addition to the release force in the release direction, a component force in the removal direction acts on the hook 46.

  In the hook 46, the hook retaining surface 62 slides on the receiving portion retaining surface 72, the hook spring portion 60 bends toward the hook disengagement prevention wall 70, and the hook disengagement prevention wall 70 is also urged by this. It bends to the back side, and a gap is generated between the hook detachment prevention wall 70 and the hook receiving portion 56, so that the hook locking portion 61 can pass between the hook receiving portion 56 and the hook detachment preventing wall 70.

  Thus, by providing the wedge-shaped portion 151 at the tip of the hook removal piece 123, when releasing the locking by the hook 46, not only the hook 46 is pressed vertically (laterally) to the back side thereof, A release force in the downward direction (withdrawal direction) can also be applied. Therefore, a component force can be applied to the hook 46, so that the hook engaging portion 61 can be appropriately released from the hook receiving portion 56, and the hook engaging portion 61 is connected to the hook disengagement prevention wall 70. And the hook receiving portion 56.

  Therefore, the tape cartridge disassembling jig 80 converts the force from the operation lever 96 into a downward force by the hand press 90, and the pushing means 110 pushes the tape cartridge 20 set in the setting means 111 downward. And a downward force can be converted into a lateral force by the cam mechanism 129 of the hook releasing means 112, and the lateral force is inclined by the wedge-shaped portion 151 of the hook removing piece 123. The downward action can be performed in one operation, and the press-fit pin 44 is released and the hook 46 is released.

  When the tape cartridge 20 is disassembled using the tape cartridge disassembling jig 80 having the above-described configuration, the label tape 22 is first peeled off. Then, the tape cartridge 20 is set in the holding block 121 while guiding the outer shape to the positioning block 120 of the setting means 111 with the upper case 40 facing down, and only the lower case 50 is held. Is rotated downward to lower the push-out pin 115 of the push-out means 110 and push the press-fit pin 44 out of the through hole 54 of the tape cartridge 20.

  As a result, each press-fit pin 44 is pushed out from each through-hole 54, and at the same time, the hook 46 passes between the hook receiving portion 56 and the hook removal prevention wall 70, and the lower case 50 is hooked to the setting means 111. The push pin 115 is inserted into the through hole 54 by being held by the portion 148, the upper case 40 falls to the base plate 122, and the cartridge case 21 is separated into the upper case 40 and the lower case 50.

  Then, the printing tape T and the like are replaced, the upper case 40 and the lower case 50 are joined again, and the label tape 22 is attached to the cartridge case 21 with the separation history of the upper case 40 and the lower case 50 written therein. Then, a new reused tape cartridge 20 is provided.

  By the way, the six push-out pins 115 are simultaneously brought into contact with and pressed against the six press-fit pins 44, so that no great bending stress is generated in the cartridge case 21 and the cartridge case 21 is not damaged.

  Further, when the push-out pin 115 pushes the press-fit pin 44 of the upper case 40, not only a downward force acts on the upper case 40, but the press-fit pin 44 has a tightening margin in the through hole 54. Since the case 40 and the lower case 50 are joined, a downward force also acts on the lower case 50. At this time, the lower case 50 is still held by the catch portion 49 of the tape cartridge disassembly jig 80. In this case, the jig receiving portion 57 of the lower case 50 is thicker than the other end faces. Since it is formed in meat, it can have sufficient strength, and damage to the end surface of the lower peripheral wall portion 52 can be prevented.

  A hooking portion 49 is further formed on the right side of the head opening 23 of the tape cartridge 20 (indicated by reference numerals in FIG. 3 and the like are omitted), and a tape cartridge disassembly jig 80 corresponding to the hooking portion 49 is formed. A hooking portion 148 may be further formed on the holding block 121 of the setting means 111. More specifically, the tape cartridge 20 has a jig receiving portion 57 formed on the guide wall 59 of the lower case 50 and a concave portion 47 formed on the right portion of the upper head opening 43 of the upper case 40, so that the tape cartridge can be disassembled and cured. When the tool 80 is set, only the lower case 50 may be held even in the central portion thereof.

  Further, in the tape cartridge disassembling jig 80 according to the present embodiment, the setting means 111 may be movable in the vertical direction with respect to the pushing means 110, and is set in parallel with the downward pressing operation by the pushing means 110. The means 111 may be moved upward.
