[0027] [1. First embodiment]
[0028] [1-1. Structure]
[0029] Figure 1A , 1B The printing apparatus 1 shown in FIG1C includes a printing tape cassette 10 and a printing apparatus body 100. The printing apparatus 1 is an apparatus for performing printing on a tape-shaped printing medium.
[0030] In this embodiment, the axial direction of the output gear 18 is the up-down direction. In the direction perpendicular to the up-down direction, the direction in which the output gear 18 and the input shaft 16 are arranged is the front-back direction. The direction perpendicular to both the up-down direction and the front-back direction is the left-right direction.
[0031] <Printing tape cassette>
[0032] The printing tape cassette 10 accommodates the printing medium. The printing tape cassette 10 can be attached to and detached from the printing apparatus body 100. By replacing the printing tape cassette 10, the printing medium can be replenished or the type of the printing medium (for example, color, material, etc.) can be changed.
[0033] like Figure 2A , 2B As shown in FIG. 2C , the printing tape cartridge 10 includes a housing 35 for accommodating a printed tape (an example of a first tape), an ink ribbon, etc., which will be described later. The outer shape of the printing tape cartridge 10 (i.e., the shape of the housing 35) is a rectangular parallelepiped having sides parallel to the up-down direction, sides parallel to the front-back direction, and sides parallel to the left-right direction. The housing 35 includes a first cover 31, a first frame 32, a second frame 33, and a second cover 34.
[0034] like Figure 3 As shown, the printing tape cassette 10 includes a first tape roll 11, a first supply shaft 12, spacers 13A and 13B, a second tape roll 14, a second supply shaft 15, an input shaft 16, a clutch spring retaining portion 17, an output gear 18, an input gear 19 and an idler gear 20.
[0035] (First volume)
[0036] The first tape roll 11 winds the printed tape to be printed on the first supply shaft 12. Printing is performed on the surface of the printed tape by a print head 102 and an ink ribbon of a printing apparatus body 100 described later.
[0037] Two spacers 13A and 13B are arranged on the outer side of the first roll 11 in the vertical direction to sandwich the first roll 11. The spacers 13A and 13B are arranged between the first roll 11 and the second cover 34 and between the first roll 11 and the second frame 33.
[0038] (First supply axis)
[0039] The first supply shaft 12 is rotatable about a rotation axis, and rotates as a platen roller 103 of a printing apparatus body 100 described later conveys a tape to be printed, thereby supplying the tape to be printed to the print head 102 .
[0040] (Second volume)
[0041] The second tape roll 14 winds an ink ribbon for printing the tape to be printed on the second supply shaft 15 .
[0042] The ink ribbon overlaps with the printed tape at the print head opening 32B described later, and is used for printing by the print head 102. The ink ribbon used for printing is taken up by the input shaft 16 described later. The clutch spring held by the clutch spring holding portion 17 applies rotation resistance to the second tape roll 14.
[0043] (Second supply shaft)
[0044] The second supply shaft 15 is rotatable around a rotation axis. The rotation axis of the second supply shaft 15 is parallel to the rotation axis of the first supply shaft 12, that is, parallel to the up-down direction.
[0045] The second supply shaft 15 rotates as the input shaft 16 winds up the ink ribbon, thereby supplying the ink ribbon to the print head 102. At least a portion of the second supply shaft 15 is disposed at a position overlapping the first tape roll 11 in the vertical direction.
[0046] (Input shaft)
[0047] The input shaft 16 is rotatable around a rotation axis, and the rotation axis of the input shaft 16 is parallel to the rotation axis of the second supply shaft 15 .
[0048] The input shaft 16 is cylindrical and has a hollow portion defined by an inner circumferential surface 16A. Spline teeth 16B are provided on the inner circumferential surface 16A of the input shaft 16. A drive shaft 105 of the printing apparatus body 100 described later is connected to the spline teeth 16B. The input shaft 16 is rotated by the drive shaft 105 to wind up the ink ribbon.
[0049] (Output gear)
[0050] The output gear 18 is a single-stage gear that outputs a driving force for conveying the tape to be printed to the outside, and transmits the driving force to the platen roller 103 via a platen gear 104 of the printing apparatus body 100 described later.
[0051] The output gear 18 has a disc that rotates around a rotation axis parallel to the up-down direction and teeth provided on a surface of the disc parallel to the up-down direction. One surface of the disc that is perpendicular to the up-down direction (i.e., the upper surface) is opposed to a cover portion 33B of the housing 35 described later in the up-down direction. A portion of the other surface of the disc that is perpendicular to the up-down direction (i.e., the lower surface) is not opposed to the housing 35 in the up-down direction.
[0052] A portion of the output gear 18 is exposed at the print head opening 32B, and a portion is located outside the housing 35. When the printing tape cartridge 10 is mounted in the printing apparatus body 100, the output gear 18 engages with the platen gear 104 at the print head opening 32B.
[0053] like Figure 4 As shown, the first tape roll 11, the output gear 18 and the second tape roll 14 (i.e., the second supply shaft 15) are arranged in the order of the first tape roll 11, the output gear 18 and the second tape roll 14 in the up-down direction. That is, the output gear 18 is located between the first tape roll 11 and the second tape roll 14 in the up-down direction.
[0054] (Input gear)
[0055] like Figure 3 As shown, the input gear 19 indirectly cooperates with the output gear 18 via an idler gear 20 described later, and transmits the driving force to the output gear 18. The driving force from the driving source of the printing apparatus body 100 is input to the input gear 19.
[0056] The input gear 19 includes an external gear 19A and a cylindrical shaft 19B. The shaft 19B is fixed to the lower surface of the external gear 19A and has spline teeth on the inner circumferential surface of the shaft 19B. The external gear 19A rotates integrally with the shaft 19B due to the driving force input to the shaft 19B.
[0057] The rotation axis of the input gear 19 (ie, the rotation axis of the external gear 19A and the rotation axis of the shaft 19B) is arranged on the same line as the rotation axis of the input shaft 16. Figure 4 As shown, the input shaft 16, the input gear 19 and the first belt reel 11 are arranged in this order in the up-down direction.
[0058] That is, the input gear 19 is located between the input shaft 16 and the first belt reel 11 in the vertical direction. In addition, at least a part of the input gear 19 is arranged at a position overlapping with the first belt reel 11 in the vertical direction.
[0059] The rotation axis of the input gear 19 passes through the hollow portion of the input shaft 16. That is, the drive shaft 105 is inserted into both the input shaft 16 and the input gear 19. As a result, the input gear 19 is not directly connected to the input shaft 16, but is rotated by the same driving source as the input shaft 16 (that is, the drive shaft 105).
[0060] (Idler)
[0061] The idler gear 20 is drivingly coupled to (ie, engaged with) the input gear 19 and the output gear 18 , and transmits the driving force input to the input gear 19 to the output gear 18 .
[0062] The idler gear 20 is a segmented gear formed by coaxially arranging a first gear 20A that matches the input gear 19 and a second gear 20B that matches the output gear 18. The diameter of the second gear 20B is smaller than the diameter of the first gear 20A. In addition, the second gear 20B is arranged at a position closer to the first belt roll 11 than the first gear 20A in the vertical direction (i.e., above). The idler gear 20 constitutes a speed reduction mechanism for reducing the speed of the driving force input to the input gear 19.
[0063] (case)
[0064] like Figure 3As shown, the first cover portion 31 constitutes the lower end portion of the printing tape cassette 10. The first frame portion 32 is arranged on the upper side of the first cover portion 31 and is connected to the first cover portion 31 in the vertical direction. The second frame portion 33 is arranged on the upper side of the first frame portion 32 and is connected to the first frame portion 32 in the vertical direction. The second cover portion 34 constitutes the upper end portion of the printing tape cassette 10. The second cover portion 34 is connected to the second frame portion 33 in the vertical direction.
[0065] The first cover 31 and the first portion below the first frame 32 constitute the first housing 41, and the first housing 41 accommodates the second tape roll 14 (i.e., at least a portion of the ink ribbon), the second supply shaft 15, and the input shaft 16. That is, the second tape roll 14, the second supply shaft 15, and the input shaft 16 are arranged in a space surrounded by the first cover 31 and the first frame 32. In addition, the first housing 41 is provided with a discharge port 32C for discharging the printed tape.
[0066] The second portion of the first frame portion 32 on the opposite side (i.e., the upper side) to the first portion in the up-down direction and the third portion on the lower side of the second frame portion 33 constitute the second housing portion 42, and the second housing portion 42 accommodates a portion of the output gear 18, the input gear 19, and the idler gear 20. That is, a portion of the output gear 18, the input gear 19, and the idler gear 20 are arranged in a space surrounded by the first frame portion 32 and the second frame portion 33.
[0067] The fourth portion of the second frame portion 33 on the opposite side (i.e., the upper side) to the third portion in the vertical direction and the second cover portion 34 constitute a third housing portion 43, and the third housing portion 43 accommodates the first tape roll 11 (i.e., at least a portion of the tape to be printed). That is, the first tape roll 11 is arranged in a space surrounded by the second frame portion 33 and the second cover portion 34.
[0068] like Figure 4 As shown, the first housing portion 41, the second housing portion 42 and the third housing portion 43 are arranged in the order of the first housing portion 41, the second housing portion 42 and the third housing portion 43 in the vertical direction. That is, the second housing portion 42 is arranged between the first housing portion 41 and the third housing portion 43 in the vertical direction.
[0069] The length of the first housing portion 41 in the vertical direction and the length of the third housing portion 43 in the vertical direction are respectively greater than the length of the second housing portion 42 in the vertical direction. Moreover, the length of the first housing portion 41 in the vertical direction is greater than the length of the third housing portion 43 in the vertical direction. In addition, the length of the second frame portion 33 in the vertical direction is greater than the length of the first frame portion 32 in the vertical direction.
[0070] like Figure 5A , 5BAs shown, the first frame portion 32 has a first side wall 32A, a print head opening 32B, a discharge port 32C, a first guide portion 32D, a protrusion 32E, a facing portion 32F, a first partition wall 32G, an opening outlet 32K, a first restricting portion 32L, and a first partition wall 32M. The first side wall 32A constitutes a side surface of the printing tape cassette 10 parallel to the up-down direction.
[0071] The print head opening 32B is a portion of the first side wall 32A cut away. The print head opening 32B is a space into which the print head 102 is inserted from below when the print tape cartridge 10 is installed in the printing device body 100, so that the print head 102 is arranged inside. The print head opening 32B opens at the bottom of the print tape cartridge 10.
[0072] The first guide portion 32D is a portion around which the to-be-printed tape 11A fed from the third housing portion 43 is wound. The first guide portion 32D includes a plurality of plate-like ribs spaced apart from each other in the circumferential direction of the second tape roll 14. The plurality of ribs protrude in the radial direction of the second tape roll 14, and the protrusion amount (i.e., the plate width) decreases as it goes downward.
[0073] The protrusion 32E is a portion that conveys the printed tape and the ink ribbon in parallel upstream of the print head opening 32B in the conveying direction of the printed tape. The protrusion 32E extends in the left-right direction. During printing, the printed tape and the ink ribbon are conveyed from left to right inside the protrusion 32E.
[0074] The protrusion 32E has a first surface 32H defining the print head opening 32B. The first surface 32H constitutes the rear surface of the protrusion 32E and is perpendicular to the front-rear direction. When the printing tape cartridge 10 is installed in the printing apparatus body 100, the first surface 32H faces the print head 102 in the front-rear direction.
[0075] The opposing portion 32F is a plate-shaped portion that opposes the protruding portion 32E in the front-to-back direction. The opposing portion 32F divides the print head opening 32B and the space where the second tape roll 14, the second supply shaft 15, and the input shaft 16 are arranged in the front-to-back direction. The opposing portion 32F defines the print head opening 32B and has a second surface 32I (see FIG. 1 ) that opposes the first surface 32H in the front-to-back direction. Figure 3 ).
[0076] The second surface 32I constitutes the front surface of the facing portion 32F and is perpendicular to the front-rear direction. When the printing tape cartridge 10 is mounted in the printing apparatus body 100, the second surface 32I is arranged on the opposite side of the first surface 32H with the print head 102 interposed therebetween.
[0077] The first partition wall 32G divides the first housing portion 41 and the second housing portion 42 in the up-down direction. In addition, the first partition wall 32G is a part of the second housing portion 42. That is, the first part of the first frame portion 32 that constitutes the first housing portion 41 is a part on the lower side of the first partition wall 32G. On the other hand, the protrusion 32E and the opposite part 32F protrude downward from the first partition wall 32G. Therefore, the protrusion 32E and the opposite part 32F are a part of the first housing portion 41.
[0078] The first partition wall 32G is disposed at the upper end of the head opening 32B in the vertical direction and has a third surface 32J connecting the protruding portion 32E and the facing portion 32F. The third surface 32J constitutes the lower surface of the first partition wall 32G and is perpendicular to the vertical direction.
[0079] The opening outlet 32K is a portion where the printed tape in the protruding portion 32E is discharged to the print head opening 32B. The opening outlet 32K is provided at the right end of the protruding portion 32E. The ink ribbon pulled out from the second tape roll 14 overlaps with the printed tape discharged from the opening outlet 32K to the print head opening 32B.
[0080] The first limiting portion 32L limits the movement of the printed tape in the width direction. The first limiting portion 32L is arranged between the two ends (i.e., the upper end and the lower end) of the discharge port 32C in the width direction (i.e., the vertical direction) of the printed tape of the first housing portion 41 (see Figure 8B Specifically, the support portion 32N protrudes leftward from the first side wall 32A at the right rear of the first frame portion 32, and the first restriction portion 32L further protrudes upward from the support portion 32N.
[0081] The first partition wall 32M divides the space where the output gear 18, the input gear 19 and the idler gear 20 are arranged and the space where the printing tape passes. Specifically, the first partition wall 32M divides the inner area opposite to the output gear 18, the input gear 19 and the idler gear 20 in the second frame portion 33 and the outer area outside the inner area.
[0082] like Figure 5C As shown, the second frame portion 33 has a second side wall 33A, a cover portion 33B, a second guide portion 33C, a first gear support portion 33D, a second gear support portion 33E, a third gear support portion 33F, a second partition wall 33G, a second isolation wall 33H, a first claw 33I, a second claw 33J, a third claw 33K, a fourth claw 33L, and a second limiting portion 33M (see Figure 8B The second side wall 33A constitutes a side surface of the printing tape cassette 10 parallel to the up-down direction.
[0083] The cover 33B is a part having a surface perpendicular to the up-down direction. The cover 33B is arranged at a position overlapping with the output gear 18 in the up-down direction. In the present embodiment, the cover 33B is continuous with the lower end of the second side wall 33A and is arranged at the right front corner of the second frame portion 33.
[0084] The output gear 18, the cover 33B and the first reel 11 are arranged in this order in the vertical direction. Furthermore, as described above, the entire area of the upper surface of the output gear 18 is covered by the cover 33B.
[0085] like Figure 6 As shown, the second guide portion 33C is a portion where the printed tape 11A pulled out from the first tape roll 11 is wound. The second guide portion 33C has a plurality of plate-like ribs arranged at intervals along the circumferential direction of the first tape roll 11. The plurality of ribs protrude in the radial direction of the first tape roll 11, and the protrusion amount (i.e., the plate width) increases as it goes downward.
[0086] like Figure 5C As shown, the first gear support portion 33D rotatably supports the output gear 18. The second gear support portion 33E rotatably supports the input gear 19. The third gear support portion 33F rotatably supports the idler gear 20.
[0087] The second partition wall 33G divides the space where the output gear 18, the input gear 19, and the idler gear 20 are arranged and the space where the printing tape passes. Specifically, the second partition wall 33G divides the inner area where the first gear support part 33D, the second gear support part 33E, and the third gear support part 33F are arranged and the outer area where the second guide part 33C is arranged in the second frame part 33. The second guide part 33C protrudes from the second partition wall 33G.
[0088] The second partition wall 33H vertically divides the second housing portion 42 and the third housing portion 43. The second partition wall 33H is a part of the third housing portion 43. That is, the third portion of the second frame portion 33 constituting the second housing portion 42 is a portion below the second partition wall 33H.
[0089] On the other hand, the first gear support portion 33D, the second gear support portion 33E, the third gear support portion 33F and the second partition wall 33G protrude downward from the second partition wall 33H. Therefore, the first gear support portion 33D, the second gear support portion 33E, the third gear support portion 33F and the second partition wall 33G are part of the second housing portion 42.
[0090] The first claw 33I is provided at the front end portion of the second frame portion 33. The second claw 33J is provided at the left end portion of the second frame portion 33. The third claw 33K is provided at the rear end portion of the second frame portion 33.
[0091] The fourth claw 33L is provided at the right end portion of the second frame portion 33 .
[0092] The claws 33I, 33J, 33K, and 33L respectively protrude downward and fit into openings or grooves provided in the first side wall 32A of the first frame portion 32. That is, the claws 33I, 33J, 33K, and 33L connect the first frame portion 32 and the second frame portion 33 in the vertical direction.
[0093] The output gear 18 , the input gear 19 , and the idler gear 20 are arranged between the first claw 33I and the third claw 33K in the front-rear direction, and between the second claw 33J and the fourth claw 33L in the left-right direction.
[0094] like Figure 8B As shown in FIG. 1 , the second restriction portion 33M restricts the movement of the printed tape in the width direction. The second restriction portion 33M protrudes rightward from the second side wall 33A at the left rear of the second frame portion 33 .
[0095] Figure 3 The second cover portion 34 shown has a third limiting portion 34A for limiting the movement of the printed tape in the width direction. The third limiting portion 34A is arranged between the two ends (i.e., the upper end and the lower end) of the first tape roll 11 in the width direction (i.e., the up-down direction) of the printed tape in the third housing portion 43 (see Figure 8B Specifically, the third restricting portion 34A is a plate-shaped member disposed at the right rear of the second cover portion 34 in such a manner that the thickness direction thereof is parallel to the left-right direction.
[0096] The volume of the internal space of the third housing portion 43 is greater than the volume of the internal space of the first housing portion 41. In addition, the total weight of the weight of the third housing portion 43 and the weight of the components accommodated in the third housing portion 43 (i.e., the first belt roll 11, the first supply shaft 12, etc.) is greater than the total weight of the weight of the first housing portion 41 and the weight of the components accommodated in the first housing portion 41 (i.e., the second belt roll 14, the second supply shaft 15, the input shaft 16, etc.).
[0097] like Figure 7 As shown in FIG. 1 , the printed tape 11A and the ink ribbon 14A are stretched in the left-right direction at the print head opening 32B. The printed tape 11A after printing is discharged to the outside of the printing apparatus 1 from the discharge port 32C.
[0098] In a projection diagram of the output gear 18 and the housing 35 onto a virtual plane perpendicular to the up-down direction, the output gear 18 is located inside the outer edge of the housing 35. In addition, the entire output gear 18 overlaps the housing 35 in the up-down direction.
[0099] like Fig. 8A , 8BAs shown in FIGS. 8C and 8D, the first guide portion 32D and the second guide portion 33C constitute a passage for conveying the to-be-printed tape 11A constituting the first tape roll 11 from the third housing portion 43 to the first housing portion 41.
[0100] Specifically, Fig. 8A As shown, the printing tape 11A pulled out from the first tape roll 11 is conveyed downward and rearward in the third housing portion 43 while abutting the second guide portion 33C from the radially outer side of the first tape roll 11 in a spiral manner. Figure 8B As shown, the to-be-printed tape 11A is conveyed toward the lower left while straddling the second housing portion 42 in the vertical direction.
[0101] like Figure 8C As shown, the printed tape 11A that has reached the first housing portion 41 through the second housing portion 42 is conveyed downward and forward while abutting against the first guide portion 32D from the radially outer side. Fig.8D As shown, the to-be-printed tape 11A that has reached the lower end of the printing tape cassette 10 through the first housing portion 41 passes through the print head opening 32B and is discharged from the discharge port 32C.
[0102] <Printing device>
[0103] like Figure 1B As shown, the printing apparatus body 100 includes a cassette insertion portion 101 , a print head 102 , a platen roller 103 , a platen gear 104 , and a drive shaft 105 .
[0104] (Cassette insertion section)
[0105] The cassette insertion portion 101 is a recessed portion for mounting the print tape cassette 10. The cassette insertion portion 101 has a function of positioning the print tape cassette 10.
[0106] (Print Head)
[0107] The print head 102 is a device for printing on the print tape held in the print tape cassette 10 .
[0108] The print head 102 is arranged inside the cassette insertion portion 101. The print head 102 is arranged at a position overlapping the to-be-printed tape and the ink ribbon in the print head opening 32B in the front-rear direction when the printing tape cassette 10 is mounted in the printing apparatus body 100.
[0109] The print head 102 has a plurality of heating elements that can control heating respectively. The platen roller 103 described later presses the printed tape conveyed to the print head opening 32B onto the print head 102 heated by the heating elements via the ink ribbon. As a result, a portion of the ink disposed on the surface of the ink ribbon is transferred to the printed tape, thereby printing characters, symbols, etc. on the printed tape.
[0110] (Pressing roller)
[0111] The platen roller 103 is a roller for conveying the printing tape from the inside to the outside of the printing tape cassette 10. The rotation axis of the platen roller 103 is parallel to the up-down direction.
[0112] The platen roller 103 is arranged near the print head 102 inside the cassette insertion portion 101. The platen roller 103 abuts against the tape to be printed located in the print head opening 32B, and presses the tape to be printed toward the print head 102.
[0113] (Pressure plate gear)
[0114] The platen gear 104 is connected to the platen roller 103 and is a driving force transmission part that cooperates with the output gear 18. In this embodiment, the rotation axis of the platen gear 104 and the rotation axis of the platen roller 103 are arranged on the same line.
[0115] The platen roller 103 and the platen gear 104 can be Fig. 9 The position shown is separated from the printing tape cassette 10 and Fig.10 The pressure plate gear 104 is shown oscillating between positions where it cooperates with the output gear 18 .
[0116] (Drive shaft)
[0117] The drive shaft 105 is a shaft into which the input shaft 16 is inserted and which cooperates with the input gear 19 to rotate the input shaft 16 and the input gear 19 .
[0118] The drive shaft 105 is disposed inside the cassette insertion portion 101. The rotation axis of the drive shaft 105 is parallel to the vertical direction. The drive shaft 105 is rotated around the rotation axis by a driving source (eg, a motor) not shown.
[0119] like Fig.10 As shown, when the printing tape cartridge 10 is installed in the printing device body 100, the drive shaft 105 cooperates with the input gear 19, and the platen gear 104 cooperates with the output gear 18. Specifically, the drive shaft 105 is inserted into the input shaft 16 and the input gear 19 of the printing tape cartridge 10, and the platen roller 103 and the platen gear 104 swing toward the print head opening 32B of the printing tape cartridge 10, thereby installing the printing tape cartridge 10 in the printing device body 100.
[0120] When the printing tape cartridge 10 is installed, the input gear 19 is rotated by the drive shaft 105 , thereby rotating the output gear 18 , rotating the platen gear 104 , and rotating the platen roller 103 .
[0121] [1-2. Effect]
[0122] According to the above-described embodiment, the following effects can be obtained.
[0123] (1a) The output gear 18 is disposed in the second housing portion 42 sandwiched between the first housing portion 41 and the third housing portion 43. Therefore, when the printing tape cartridge 10 falls and a surface perpendicular to the axial direction of the rotation axis of the output gear 18 collides with the ground or the like, the output gear 18 is protected by the first housing portion 41 and the third housing portion 43, and damage to the output gear 18 can be suppressed.
[0124] (1b) Since the protruding portion 32E and the facing portion 32F are connected via the third surface 32J, the strength of the protruding portion 32E is improved. As a result, it is possible to suppress the protruding portion 32E from being damaged when the printing tape cassette 10 is dropped.
[0125] (1c) Since the volume and total weight of the third housing portion 43 are greater than those of the first housing portion 41, when the printing tape cartridge 10 falls, the third housing portion 43 is placed on the lower side and collides with the ground, etc. Therefore, it is possible to suppress damage to the output gear 18 exposed in the print head opening 32B provided in the first housing portion 41.
[0126] (1d) Since the housing parts are divided by the partition wall, when the print tape cassette 10 falls, it is possible to suppress the collision of components arranged in different housing parts. Therefore, it is possible to suppress damage to the components.
[0127] (1e) The tape to be printed wound around the first supply shaft 12 can be smoothly conveyed from the third housing portion 43 to the first housing portion 41 by the first restricting portion 32L, the second restricting portion 33M, and the third restricting portion 34A.
[0128] (1f) In the second case portion 42 , the first partition wall 32M and the second partition wall 33G can suppress interference between the printed tape fed to the discharge port 32C and the output gear 18 , the input gear 19 , and the idler gear 20 .
[0129] [2. Second Embodiment]
[0130] [2-1. Structure]
[0131] Fig.11A and 11B The printing apparatus 1A shown includes a printing tape cassette 10A and a printing apparatus body 100A.

[0133] The printing tape box 10A adds a third tape roll 21, an additional shaft 22, an additional gear 23 and a clamping roller 24 as shown in Figure 11 to the printing tape box 10 of the first embodiment, and replaces the input shaft 16, the first cover portion 31, the first frame portion 32, the second frame portion 33 and the second cover portion 34 of the first embodiment with a third supply shaft 25, a first cover portion 36, a first frame portion 37, a second frame portion 38 and a second cover portion 39.
[0134] The first cover portion 36 and the first frame portion 37 constitute a first case portion 41A. The first frame portion 37 and the second frame portion 38 constitute a second case portion 42A. The second frame portion 38 and the second cover portion 39 constitute a third case portion 43A.
[0135] The third supply shaft 25 is the same as the input shaft 16 except that it does not have the spline teeth 16B. The first cover portion 36, the first frame portion 37, the second frame portion 38, and the second cover portion 39 extend the first cover portion 31, the first frame portion 32, the second frame portion 33, and the second cover portion 34 in the left-right direction, respectively. Since the other structures of the printing tape cartridge 10A are the same as those of the printing tape cartridge 10 of the first embodiment except for the points described below, the description thereof is omitted.
[0136] The third tape roll 21 winds a laminated tape for protecting the tape to be printed on the third supply shaft 25. The laminated tape has an adhesive surface and is bonded to the tape to be printed by the print head 102.
[0137] The additional shaft 22 is rotatable about a rotation axis. The rotation axis of the additional shaft 22 is parallel to the rotation axis (ie, in the vertical direction) of the second supply shaft 15. The additional shaft 22 is a winding shaft for winding up the ink ribbon by the rotation of an additional gear 23 described later.
[0138] The additional gear 23 is connected to the additional shaft 22 and cooperates with the idler gear 20. The additional gear 23 is rotated by the driving force input to the input gear 19, thereby rotating the additional shaft 22.
[0139] The pinch roller 24 presses the laminated tape onto the printed tape together with the pressure roller 106 described later. The pinch roller 24 is arranged downstream of the print head opening 32B in the conveying direction of the printed tape.
[0140] At least a portion of the printed tape (i.e., the portion pulled out from the first tape roll 11), at least a portion of the laminated tape, and at least a portion of the clamping roller 24 are arranged in a direction perpendicular to the up-down direction (i.e., the front-to-back direction and the left-to-right direction) and accommodated in the first housing portion 41A.
[0141] Furthermore, the pinch roller 24 is supported by the second housing portion 42A so that at least a portion of the pinch roller 24 overlaps the second housing portion 42A in the direction perpendicular to the up-down direction (ie, the front-rear direction and the left-right direction).
[0142] Specifically, the upper end portion of the shaft portion 24A of the pinch roller 24 is inserted into a recessed portion 371 provided in the first partition wall 32G of the first frame portion 37. The recessed portion 371 is a part of the second case portion 42A.
[0143] <Printing device>
[0144] The printing apparatus body 100A is formed by adding the following components to the printing apparatus body 100 of the first embodiment: Fig.13 The pressure roller 106 is shown. Since the other structures of the printing apparatus body 100A are the same as those of the printing apparatus body 100 of the first embodiment except for the points described below, the description thereof will be omitted.
[0145] The pressure roller 106 is configured to be able to swing together with the platen roller 103 and the platen gear 104. That is, the pressure roller 106 can swing in the following manner: Fig.13 The position shown in FIG. 10A away from the printing tape cassette 10A and the Fig.14 The illustrated embodiment swings between positions where the printed tape and the laminated tape are pressed together with the pinch roller 24 .
[0146] [2-2. Effect]
[0147] According to the above-described embodiment, the following effects can be obtained.
[0148] (2a) The printed content of the printed tape can be protected by the laminated tape, while having the same advantages as the first embodiment.
[0149] (2b) Since a portion of the pinch roller 24 overlaps the second case portion 42A in the direction perpendicular to the up-down direction, it is easy to assemble the pinch roller 24 to the case 35. As a result, the productivity of the printing tape cassette 10A is improved.
[0150] [3. Other embodiments]
[0151] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various forms can be adopted.
[0152] (3a) The printing device of the above embodiment is not limited to printing using an ink ribbon. The printing device may use a tape-shaped thermal paper as a printed tape for printing. In addition, the printing device does not necessarily have an ink ribbon roll and a second supply shaft.
[0153] For example, in Fig.15In the printing tape cassette 10B shown, the first tape roll 11 in the printing tape cassette 10 of the first embodiment is replaced by a thermal paper roll 51, and the second tape roll 14 is replaced by a third tape roll 52 of a laminated tape.
[0154] In the printing tape cassette 10B, the third tape roll 52 is wound around the third supply shaft 25 of the second embodiment. In addition, the printing tape cassette 10B includes the pinch roller 24 of the second embodiment, but does not include the second supply shaft 15.
[0155] (3b) In the printing tape cassette of the above embodiment, the relationship between the volume, total weight and length in the vertical direction of the first housing portion, the second housing portion and the third housing portion is not limited to the above relationship. In addition, the first housing portion, the second housing portion and the third housing portion may be composed of components other than the above-mentioned first cover portion, the first frame portion, the second frame portion and the second cover portion.
[0156] (3c) In the printing tape cassette of the second embodiment, the laminated tape may be wound around an additional shaft.
[0157] For example, in Fig.16 In the printing tape cassette 10C shown, the third tape roll 21 of the laminated tape is wound around the additional shaft 22 in the printing tape cassette 10A of the second embodiment. The printing tape cassette 10C includes the input shaft 16 of the first embodiment instead of the third supply shaft 25 of the second embodiment. The input shaft 16 is used as a winding shaft for the ink ribbon.
[0158] (3d) The functions of a single component in the above-mentioned embodiment may be dispersed into multiple components, or the functions of multiple components may be integrated into a single component. In addition, part of the structure of the above-mentioned embodiment may be omitted. In addition, at least part of the structure of the above-mentioned embodiment may be added to or replaced by the structure of other embodiments. All embodiments included in the technical concept of the claims are embodiments of the present invention.
