Description

TECHNICAL FIELD

[0001] The present disclosure relates to a cutting device and a printing device including the cutting device. BACKGROUND

[0002] A cutting device for cutting a target to be cut, such as a tape, a label, a tube, or the like, is known. Further, a printer employing the above cutting device is also known. For example, Japanese Patent Application Publication No. 2005-224924 discloses a cutting device including a motor for driving a movable blade. The movable blade is driven by the motor to cut a label sheet in cooperation with a cutter carriage.

[0003] According to the conventional cutting device described above, the following problem arises: since the motor for driving the movable blade is provided in the cutting device, the weight of the cutting device is increased. SUMMARY

[0004] In view of the foregoing, an object of the present disclosure is to provide a cutting device whose weight is reduced and a printing device including the cutting device.

[0005] (1) To achieve the above and other objects, the present disclosure provides a cutting device including: a cutter blade; a cutter holder; a cutter carriage; a cutter lever; and a cutter carriage lever. The cutter blade is configured to cut a cutting target. The cutter holder holds the cutter blade, and the cutter holder is movable with the cutter blade. The cutter carriage faces the cutter holder. The cutter carriage is movable between: a full-cutting position at which the cutter carriage and the cutter blade are configured to perform a full-cutting operation with respect to the cutting target in cooperation with each other; and a half-cutting position at which the cutter carriage and the cutter blade are configured to perform a half-cutting operation with respect to the cutting target in cooperation with each other. The cutter lever is configured to be operated by a user. The cutter lever is configured to be in contact with the cutter holder to cause movement of the cutter holder. The cutter carriage lever is configured to be operated by the user. Movement of the cutter carriage lever causes movement of the cutter carriage. When only the cutter lever is operated by the user, movement of the cutter blade with the cutter holder is caused by movement of the cutter lever, so that the cutter blade and the cutter carriage located at the half-cutting position perform the half-cutting operation with respect to the cutting target in cooperation with each other. When the cutter lever and the cutter carriage lever are operated by the user, movement of the cutter carriage to the full-cutting position is caused by movement of the cutter carriage lever, and movement of the cutter blade with the cutter holder is caused by movement of the cutter lever, so that the cutter blade and the cutter carriage that has moved to the full-cutting position perform the full-cutting operation with respect to the cutting target in cooperation with each other.

[0006] The cutting device according to the above aspect (1) is configured to perform one of a full-cutting operation and a half-cutting operation with respect to a cutting target using a cutter lever and a cutter carriage lever that are operated by a user.

[0041] Hereinafter, a printing device 1 according to a first embodiment of the present disclosure will be described with reference to Figures 1 to 17

[0042] The terms "upward", "downward", "leftward", "rightward", "forward" and "backward" used in the following description correspond to the terms "up", "down", "left", "right", "front" and "back" in the drawing, respectively, as indicated by arrows. Furthermore, the upward direction and the downward direction will be collectively referred to as the up-down direction, the leftward direction and the rightward direction will be collectively referred to as the left-right direction, and the forward direction and the backward direction will be collectively referred to as the front-back direction.

[0043] [Outline of Printing Device 1]

[0044] Figure 1 The printing device 1 shown in Figure 4 includes a housing 1A, an operation portion 1B, a display portion 1C, a cover 1D, and a cutting device 1E. The housing 1A has a substantially rectangular shape in a plan view. The operation portion 1B is provided at a lower front portion of the housing 1A, i.e., is positioned further downward than the substantially central portion of the housing 1A in the up-down direction. The operation portion 1B is configured to receive input of various information by user operation. In the user operation, the user directly touches the operation portion 1B to input information. The display portion 1C is located at a front portion of the housing 1A, and is positioned further upward than the operation portion 1B. The display portion 1C is configured to display various information on the display portion 1C.

[0045] As shown in Figure 2 , the printing device 1 further includes a cartridge receiving portion 2 configured to receive a cartridge 9. The cartridge receiving portion 2 is opened or closed by the cover 1D (see Figure 1 ) having a plate-like shape. The housing 1A has a rear end portion formed with an opening 12 communicating with the cartridge receiving portion 2.

[0046] The head holder 21, the tape driving shaft 22A, the ribbon take-up shaft 22B, a driving motor (not shown), and an auxiliary shaft 22C are provided in Figure 2 ​​The cartridge receiving section 2 is shown in the diagram. The head holder 21 extends rearward from the right side of the cartridge receiving section 2. The printhead 21A (see...) Figure 3 The printhead 21A is disposed on the right surface of the printhead holder 21. The printhead 21A is a hot head, which includes a plurality of heat-generating elements arranged in the front-to-back direction.

[0047] A belt drive shaft 22A is positioned above the head holder 21. A ribbon take-up shaft 22B is positioned to the left of the head holder 21. Each of the belt drive shaft 22A and the ribbon take-up shaft 22B is rotatable about an axis extending in the front-rear direction. A drive motor is connected to and drives the belt drive shaft 22A and the ribbon take-up shaft 22B. Accordingly, when driven by the drive motor, the belt drive shaft 22A and the ribbon take-up shaft 22B are rotated in a linked relationship with each other. An auxiliary shaft 22C has an axis extending in the front-rear direction and is fixed to the cartridge receiving section 2 at a position to the left of the belt drive shaft 22A and the ribbon take-up shaft 22B.

[0048] As in Figure 3 As shown, a pressure plate holder 23 extending in the vertical direction is positioned to the right of the cartridge receiving section 2. The pressure plate holder 23 supports the pressure plate roller 23B and the transfer roller 23C. Each of the pressure plate roller 23B and the transfer roller 23C is rotatable about an axis extending in the front-rear direction. The pressure plate roller 23B is located on the right and faces the print head 21A, while the transfer roller 23C is located on the right and faces the belt drive shaft 22A.

[0049] The lower end of the pressure plate retainer 23 is supported by a shaft 23A extending in the front-rear direction, allowing the pressure plate retainer 23 to pivotally move. Specifically, the pressure plate retainer 23 can be positioned about the shaft 23A in a proximal position (see...). Figure 3 The platen retainer 23 pivots between a proximal position and a distal position (not shown). With the platen retainer 23 in the proximal position, the platen roller 23B and the transfer roller 23C are positioned close to the printhead 21A and the belt drive shaft 22A, respectively. With the platen retainer 23 in the distal position, the platen roller 23B and the transfer roller 23C are located to the right, spaced apart from the printhead 21A and the belt drive shaft 22A, respectively.

[0050] As the pressure plate holder 23 pivots from the distal position to the proximal position, the pressure plate roller 23B is switched to a state where it is coupled to and driven by a motor. The pressure plate holder 23 can move from the distal position to the proximal position as the cover 1D for closing the cartridge receiving section 2 is moved. The position of the pressure plate holder 23 between the pressure plate roller 23B and the print head 21A when it is in the proximal position is referred to as the "printing position".

[0051] [Overview of Box 9]

[0052] As shown in Figure 2 the box 9 as a stacked type cartridge can be attached to the cartridge receiving portion 2. The cartridge 9 includes a housing 90 having a cartridge-like shape. The housing 90 houses a tape driving roller 91 therein, and is formed with support holes 92A, 92B, 92C, and 92D that penetrate the housing 90 in the front-rear direction, and an ejection portion 93.

[0053] The tape driving roller 91 is located in the right upper corner portion of the housing 90, and has a hollow cylindrical shape that extends in the front-rear direction. The tape driving roller 91 is rotatably supported by the housing 90. In a state where the cartridge 9 is mounted on the cartridge receiving portion 2, the tape driving shaft 22A is inserted into the inner space of the tape driving roller 91.

[0054] The support hole 92A rotatably supports a first tape spool 96A. A transparent film tape 99A is wound around the first tape spool 96A to constitute a first tape roll 97A. The transparent film tape 99A is paid out from the first tape roll 97A by rotation of the first tape roll 97A along with the first tape spool 96A around an axis that extends in the front-rear direction.

[0055] The support hole 92B rotatably supports a second tape spool 96B. A double-sided tape 99B is wound around the second tape spool 96B to constitute a second tape roll 97B. The double-sided tape 99B is a double-sided tape to which a release sheet is attached to one surface. The double-sided tape 99B is paid out from the second tape roll 97B when the second tape roll 97B rotates along with the second tape spool 96B around an axis that extends in the front-rear direction. The double-sided tape 99B is guided toward the tape driving roller 91. When the cartridge 9 is attached to the cartridge receiving portion 2, the auxiliary shaft 22C is inserted into the inner space of the support hole 92B.

[0056] The support hole 92C rotatably supports a ribbon spool 96C. A new (unused) ink ribbon 99C is wound around the ribbon spool 96C to constitute a ribbon roll 97C. The ink ribbon 99C is paid out from the ribbon roll 97C when the ribbon roll 97C rotates along with the ribbon spool 96C around an axis that extends in the front-rear direction.

[0057] The support hole 92D rotatably supports a ribbon take-up spool 96D. A used ink ribbon 99C is constituted to be wound around the ribbon take-up spool 96D to constitute a ribbon take-up roll 97D. The used ink ribbon 99C is taken up by the ribbon take-up spool 96D to form the ribbon take-up roll 97D by rotation of the ribbon take-up roll 97D along with the ribbon take-up spool 96D around an axis that extends in the front-rear direction. When the cartridge 9 is attached to the cartridge receiving portion 2, the ribbon take-up shaft 22B is inserted into the inner space of the support hole 92D.

[0058] The ejection portion 93 has an opening that is open in the up-down direction at a position rightward and upward of the tape driving roller 91.

[0059] The housing 90 is formed with a head opening 94A into which the head holder 21 can be inserted. The head opening 94A is formed in the right portion of the housing 90 so as to penetrate the housing 90 in the front-rear direction. The housing 90 includes an arm portion 94B at a position right of the head opening 94A. The arm portion 94B extends in the up-down direction and has an upper end portion at which a first tape guide 95A (see Figure 3 ) is provided. The first tape guide 95A is an opening portion through which the ink color tape 99C and the transparent film tape 99A located right of the ink color tape 99C are discharged.

[0060] The transparent film tape 99A and the ink color tape 99C discharged from the first tape guide 95A pass through the head opening 94A and are then guided toward a second tape guide 95B formed in the cartridge 9. The second tape guide 95B is an opening formed between the head opening 94A and the tape driving roller 91. The ink color tape 99C is separated from the transparent film tape 99A and is conveyed left at a portion between the second tape guide 95B and the tape driving roller 91 and is then taken up by the color tape take-up spool 96D. In the following description, the position at which the ink color tape 99C is separated from the transparent film tape 99A will be referred to as a “separation position”.

[0061] The transparent film tape 99A conveyed to the portion above the separation position is guided to the tape driving roller 91 at which the transparent film tape 99A is to be laminated on the right surface (the other surface) of the double-coated tape 99B. In the following description, the combination of the transparent film tape 99A and the double-coated tape 99B laminated to each other will be referred to as a “cut target 99”. The cut target 99 is a tape whose width direction coincides with the front-rear direction. The cut target 99 has a thickness of, for example, 100 μm.

[0062] [Cutting device 1E]

[0063] As shown in Figure 3 , the cutting device 1E is provided further upward than the tape driving shaft 22A. As shown in Figure 4 , the cutting device 1E includes a carriage portion 10A, a cutter portion 10B, and a lever portion 10C. The cutting device 1E is configured to perform a cutting operation with respect to the cut target 99 by cooperation of a cutter carriage 4A of the carriage portion 10A and a cutter blade 30 (see Figure 9 ) of the cutter portion 10B. The cutting operation is performed by a user operation with respect to the lever portion 10C.

[0064] The cutting operation is classified into a full cutting operation and a half cutting operation. By the full cutting operation, the cutting target 99 is completely cut in the thickness direction of the cutting target 99 along the extension direction of the cutting edge of the cutter blade 30, and is divided into two parts. Note that the extension direction of the cutting edge coincides with the front-rear direction. By the half cutting operation, the cutting target 99 is partially cut. That is, a cut is formed in the thickness direction of the cutting target 99, but the cutting target 99 is not divided into two parts in the half cutting operation.

[0065] [Cutting device 1E]

[0066] The cutting device 1E is configured to perform a cutting operation with respect to the cutting target 99 in cooperation with the cradle portion 10A (described later). As shown in Figure 4 , Figure 8 and Figure 10 , the cutting device 1E further includes the box member 31, the cutter holder 32, and the cutter spring (not shown). Figure 4 , Figure 8 and Figure 10 are perspective views of the cutting device 1E viewed from the obliquely right lower side of the cutting device 1E. The box member 31 is open to the left. The central portion of the right end portion of the box member in the front-rear direction is formed with a notch hole 31A that is open to the right and extends in the up-down direction.

[0067] The cutter holder 32 is located inside the box member 31 and is movable in the left-right direction. The cutter holder 32 has a left end portion that holds the cutter blade 30 (see Figure 8 and Figure 10 ) for cutting the cutting target 99. The cutter blade 30 has a plate shape having a thickness in the up-down direction. The cutter blade 30 has a left edge that forms a cutting edge extending in the front-rear direction. The cutter blade 30 is movable in the left-right direction together with the cutter holder 32.

[0068] When the cutter holder 32 is at its rightmost position within its movable range, the cutter blade 30 is accommodated in the box member 31 (see Figure 4 ). On the other hand, when the cutter holder 32 is at its leftmost position within its movable range, the cutter blade 30 protrudes to the left from the box member 31 (see Figure 8 and Figure 10 ). As shown in Figure 8 and Figure 10 , the cutter blade 30 has a length "L30" in the extension direction of the cutting edge (i.e., the front-rear direction).

[0069] In the following description, as Figure 4The position of the cutter blade 30 housed in the box member 31 shown will be referred to as the "retracted position". When the cutter blade 30 is in the retracted position, the cutter blade 30 is separated from the cutting target 99 and does not contact the cutting target 99. Furthermore, as... Figure 8 and Figure 10 The position of the cutter blade 30 protruding to the left from the box member 31 shown will be referred to as the "cutting position". When the cutter blade 30 is in the cutting position, the cutter blade 30 is in contact with the cutting target 99.

[0070] A cutter spring (not shown) is located inside the housing member 31. The cutter spring pushes the cutter retainer 32, causing the cutter blade 30 to be pushed from the cutting position toward the retracted position.

[0071] [Lever Section 10C]

[0072] The lever portion 10C is configured to cause the cutter portion 10B and the bracket portion 10A (described later) to move in response to user input to the lever portion 10C. Figure 4 As shown, the lever portion 10C includes a cutter lever 5, a cutter bracket lever 6, and a cutter lever spring (not shown). The cutter lever 5 and the cutter bracket lever 6 are arranged in the front-rear direction. Specifically, the cutter lever 5 is located in front of the cutter bracket lever 6. Inside the housing 1A, the cutter lever 5 and the cutter bracket lever 6 are connected by a lever shaft 100 extending in the front-rear direction (see...). Figure 6 The levers 5 and 6 are supported, allowing them to pivot about the lever axis 100. Each of the cutter lever 5 and the cutter bracket lever 6 can pivot via user operation.

[0073] Figures 4 to 7 The corresponding positions of the cutter lever 5 and the cutter bracket lever 6 when not operated by the user are shown. In the following description, unless otherwise specified, the shape and configuration of the cutter lever 5 and the cutter bracket lever 6 will be described based on the orientation (such as front-back, left-right, and up-down) in the printing device 1 under the assumption that no user operation has been performed.

[0074] As in Figures 4 to 7 As shown, the cutter lever 5 includes a sleeve portion 50, an operating portion 51, a protrusion 52, and an extension portion 53. The operating portion 51 is the part that can be operated by the user. Meanwhile, the housing 1A has an upper right corner portion with an opening 11 formed therein (see...). Figure 1 and Figure 2 The operating part 51 protrudes outward from the housing 1A through the opening 11, that is, to the right and upward.

[0075] A sleeve portion 50 is provided on the left end of the operating portion 51. The sleeve portion 50 has a hollow cylindrical shape and defines an internal space within it. Lever shaft 100 (see...) Figure 6 The connection 63B between the cutter bracket lever 6 (described later) and the cutter bracket lever 6 (see) Figures 13 to 15 The sleeve portion 50 is inserted through the internal space of the sleeve portion 50 to allow the sleeve portion 50 to pivot about the lever axis 100. With this configuration, the operating portion 51 is pivotally supported by the lever axis 100 passing through the sleeve portion 50.

[0076] A protrusion 52 is provided on the rear surface of the operating part 51 to protrude rearward from the rear surface. The protrusion 52 includes an inlet 52A that extends obliquely to the left and downward. An extension 53 extends obliquely to the left and downward from the lower right corner of the operating part 51.

[0077] The cutter lever spring (not shown) is a torsion spring mounted on the lever shaft 100. Viewed from the rear side of the cutter lever 5, the cutter lever spring is... Figure 4 Arrow C51 indicates that the cutter lever 5 is pushed clockwise. Due to the pushing force of the cutter lever spring, the maximum pushing position of the cutter lever 5 in the clockwise direction C51 is referred to as the "half-cutting standby position." When the cutter lever 5 is not operated by the user, the cutter lever 5 is pushed by the cutter lever spring to be in the half-cutting standby position. Accordingly, Figures 4 to 7 The cutter lever 5 is shown in the half-cutting standby position.

[0078] On the other hand, in response to user operation of the operating section 51 of the cutter lever 5, such as Figure 8 As shown, the cutter lever 5 overcomes the pushing force of the cutter lever spring and pivots in the direction opposite to direction C51, i.e., in the counterclockwise direction indicated by arrow C52. The maximum position of movement of the cutter lever 5 in the counterclockwise direction C52 will be referred to as the "half-cutting operation position".

[0079] As in Figures 4 to 7 As shown, the cutter bracket lever 6 includes an operating part 61 and a contact part 62 (see...). Figures 13 to 15 The cutter lever 5 includes an extension 63 and a cutter bracket lever spring (not shown). The operating part 61 is a user-operable portion. The operating part 61 is located behind the operating part 51 of the cutter lever 5. Similar to the operating part 51 of the cutter lever 5, the operating part 61 protrudes outward (to the right and upward) through the opening 11 of the housing 1A. In plan view, the operating part 61 has a shape substantially consistent with the operating part 51.

[0080] The contact portion 62 is provided at the front surface of the operation portion 61 so as to protrude forward from the front surface. The contact portion 62 is capable of contacting the protruding portion 52 of the cutter lever 5. In the following description, the combination of the protruding portion 52 and the contact portion 62 will sometimes be referred to as the "linkage portion 10D".

[0081] As shown in Figure 5 , the operation portion 61 has a left end portion at which the extension portion 63 is provided. Figure 5 is a perspective view of the cutting device 1E as viewed from the right upper side of the cutting device 1E. The extension portion 63 includes a disc portion 63A, a connecting portion 63B (see Figures 13 to 15 ), and an arm portion 63C. The disc portion 63A extends leftward along the rear surface of the sleeve portion 50 of the cutter lever 5 from the left end portion of the operation portion 61. A circular hole is formed at the center portion of the disc portion 63A so as to penetrate the center portion of the disc portion 63A in the front-rear direction.

[0082] The connecting portion 63B has a hollow cylindrical shape formed with a through-hole extending in the front-rear direction. The connecting portion 63B extends forward from the front surface of the disc portion 63A through the inner space of the sleeve portion 50 of the cutter lever 5. The connecting portion 63B has a front end portion protruding further forward than the sleeve portion 50 of the cutter lever 5. The through-hole of the connecting portion 63B communicates with the hole of the disc portion 63A.

[0083] The lever shaft 100 (see Figure 6 ) is inserted through the through-hole of the connecting portion 63B to allow the connecting portion 63B to pivotally move about the lever shaft 100. That is, the operation portion 61 is pivotally movably supported by the lever shaft 100 passing through the disc portion 63A and the connecting portion 63B. As shown in Figure 6 , the arm portion 63C extends leftward and from the left end portion of the connecting portion 63B. The arm portion 63C is formed with a through-hole 631 (see Figure 11 ) penetrating the arm portion 63C in the front-rear direction.

[0084] The cutter carriage lever spring (not shown) is a torsion spring provided on the lever shaft 100. As viewed from the rear side of the cutter carriage lever 6, the cutter carriage lever spring pushes the cutter carriage lever 6 in the clockwise direction as indicated by the arrow C61 in Figure 4 and Figure 8 . Due to the pushing force of the cutter carriage lever spring, the maximum pushing position of the cutter carriage lever 6 in the clockwise direction C61 will be referred to as the "full-cut standby position". When the cutter carriage lever 6 is not operated by the user, the cutter carriage lever 6 is pushed by the cutter carriage lever spring and is located at the full-cut standby position. Accordingly, Figures 4 to 7 shows the cutter carriage lever 6 located at the full-cut standby position.

[0085] In another aspect, as shown in Figure 10 , in response to the user operation of the operation portion 61 of the cutter holder lever 6, the cutter holder lever 6 is pivotally moved in the direction opposite to the direction C61, i.e., in the counterclockwise direction indicated by the arrow C62, against the urging force of the cutter holder lever spring. The maximum moving position of the cutter holder lever 6 in the counterclockwise direction C62 will be referred to as the "full-cut operation position".

[0086] Note that when the operation portion 61 of the cutter holder lever 6 is operated by the user, the contact portion 62 of the cutter holder lever 6 comes into contact with the protruding portion 52 of the cutter lever 5 to apply a force directed in the direction indicated by the arrow C52 to the cutter lever 5. By applying the force to the cutter lever 5, the cutter lever 5 is pivotally moved in the direction C52 in a linked relationship with the pivotal movement of the cutter holder lever 6.

[0087] That is, as shown in Figure 10 , by the user operation of the cutter holder lever 6 alone, the movement of the cutter lever 5 from the half-cut standby position to the half-cut operation position is simultaneously performed in a linked relationship with the movement of the cutter holder lever 6 from the full-cut standby position to the full-cut operation position. In another aspect, when the cutter lever 5 is moved from the half-cut standby position to the half-cut operation position by the user operation of the cutter lever 5 alone, the movement of the cutter holder lever 6 along with the movement of the cutter lever 5 is not performed, and the cutter holder lever 6 is maintained at the full-cut standby position (see Figure 8 ).

[0088] During the movement of the cutter lever 5 from the half-cut standby position (see Figure 4 ) to the half-cut operation position (see Figure 8 and Figure 10 ), the entry portion 52A of the cutter lever 5 enters the notched hole 31A of the box member 31 of the cutter portion 10B. At this time, the cutter holder 32 located inside the box member 31 receives the force applied from the entry portion 52A to be moved to the left, thereby moving the cutter blade 30 from the retracted position to the cutting position to the left. As shown in Figure 8 and Figure 10 , the cutter blade 30 located at the cutting position protrudes to the left from the box member 31.

[0089] [Holder portion 10A]

[0090] The holder portion 10A is configured to switch the cutting operation with respect to the cutting target 99 in cooperation with the cutter portion 10B between the full-cut operation and the half-cut operation along with the user operation of the lever portion 10C. As shown in Figures 4 to 7 , the holder portion 10A includes a cutter holder 4A and a pivotal member 4B.

[0091] The cutter holder 4A has a substantially rectangular parallelepiped shape (a box shape) and is elongated in the front-rear direction. The cutter holder 4A is disposed leftward of the cutter holder 32 so as to face the cutter holder 32. As shown in Figure 12 The cutter holder 4A includes an upper wall 40U, a lower wall 40S, a rear wall 40B, a right wall 40R, and a left wall 40L. The upper wall 40U, the lower wall 40S, the rear wall 40B, the right wall 40R, and the left wall 40L constitute the upper end, the lower end, the rear end, the right end, and the left end of the cutter holder 4A, respectively.

[0092] The right wall 40R extends perpendicular to the left-right direction and is located leftward of the cutter holder 32. The upper wall 40U is connected to the upper end of the right wall 40R. The lower wall 40S is connected to the lower end of the right wall 40R. The upper wall 40U and the lower wall 40S are positioned to extend away from the cutter holder 32, i.e., to the left.

[0093] The upper wall 40U extends perpendicular to the up-down direction. The lower wall 40S is inclined with respect to an imaginary plane perpendicular to the up-down direction. As shown in Figures 13 to 15 With these walls extending to the right, the gap between the upper wall 40U and the lower wall 40S gradually increases. The cutter holder 4A has a front end formed with a front opening 40A (see Figure 12 ) that opens forward. The front opening 40A communicates with an internal space 40C (see Figures 13 to 15 ) defined by the walls 40U, 40S, 40B, 40R, and 40L.

[0094] A support portion 26 (see Figure 12 ) having a plate shape is disposed in the cartridge receiving portion 2 of the housing 1A. The support portion 26 extends rearward from the bottom surface (front inner surface) of the cartridge receiving portion 2 and extends perpendicular to the up-down direction. The cutter holder 4A is movably supported by the support portion 26.

[0095] Specifically, the support portion 26 is inserted into the internal space 40C of the cutter holder 4A through the front opening 40A so that the cutter holder 4A is disposed on the support portion 26. The support portion 26 is positioned opposite the cutter holder 32 with respect to the right wall 40R. The support portion 26 has a length in the left-right direction that is substantially equal to the length in the left-right direction of the internal space 40C defined by the right wall 40R and the left wall 40L of the cutter holder 4A (see Figures 13 to 15 ).

[0096] The cutter holder 4A is attachable to and detachable from the support portion 26. For example, after the cutter holder 4A has deteriorated due to use of the printing device 1, the user can replace the cutter holder 4A attached to the support portion 26 with a new cutter holder 4A.

[0097] As shown in Figures 13 to 15 The cutter carriage 4A further includes a first protrusion 401, a second protrusion 402, a third protrusion 403, and a fourth protrusion 404. The first protrusion 401 protrudes from the left end portion of the upper wall 40U inward of the interior space 40C. The second protrusion 402 protrudes from the left end portion of the lower wall 40S inward of the interior space 40C. The gap in the up-down direction between the first protrusion 401 and the second protrusion 402 is substantially equal to the thickness of the support portion 26 (i.e., the length of the support portion 26 in the up-down direction). The first protrusion 401 and the second protrusion 402 sandwich the left end portion of the support portion 26 located within the interior space 40C in cooperation with each other in the up-down direction.

[0098] The third protrusion 403 protrudes from the right end portion of the upper wall 40U inward of the interior space 40C. The fourth protrusion 404 protrudes from the right end portion of the lower wall 40S inward of the interior space 40C. The gap in the up-down direction between the third protrusion 403 and the fourth protrusion 404 is greater than the thickness of the support portion 26.

[0099] As shown in Figure 13 and Figure 14 The right end portion of the cutter carriage 4A is movable downward until the third protrusion 403 abuts against the upper surface of the support portion 26. Further, as shown in Figure 15 The right end portion of the cutter carriage 4A is movable upward until the fourth protrusion 404 abuts against the lower surface of the support portion 26. Accordingly, the cutter carriage 4A is pivotally movable in the up-down direction about the left end portion of the cutter carriage 4A sandwiching the support portion 26 by the first protrusion 401 and the second protrusion 402.

[0100] Figure 13 and Figure 14 shows the "half-cut position" of the cutter carriage 4A at which the third protrusion 403 abuts against the support portion 26 to place the cutter carriage 4A at the maximum pivotal movement position in the counterclockwise direction when viewed from the rear side of the cutter carriage 4A. On the other hand, Figure 15 shows the "full-cut position" of the cutter carriage 4A at which the fourth protrusion 404 abuts against the support portion 26 so that the cutter carriage 4A is at the maximum pivotal movement position in the clockwise direction when viewed from the rear side thereof. Accordingly, the cutter carriage 4A is pivotally movable between the half-cut position and the full-cut position.

[0101] As shown in Figures 12 to 15As shown in FIG. 10, the contact portion 41 is provided on the upper wall 40U. The contact portion 41 includes a first contact portion 41A, a second contact portion 41B, and a third contact portion 41C having a plate-like shape. The first contact portion 41A has a surface extending perpendicularly to the left-right direction, and extends upward from a right end portion of the upper wall 40U. The first contact portion 41A has a length in the front-rear direction that is approximately half of a length of the upper wall 40U in the front-rear direction.

[0102] The second contact portion 41B extends obliquely leftward and downward from an upper end portion of a left surface of the first contact portion 41A. The second contact portion 41B has a length in the front-rear direction that is approximately one-third of a length of the first contact portion 41A in the front-rear direction.

[0103] The third contact portion 41C extends downward from a left end portion of the second contact portion 41B, and is connected to the upper wall 40U. The third contact portion 41C has a length in the front-rear direction that is equal to a length of the second contact portion 41B in the front-rear direction. A portion surrounded by the first contact portion 41A, the second contact portion 41B, and the third contact portion 41C will be referred to as an “insertion portion 410”. The upper wall 40U, the first contact portion 41A, the second contact portion 41B, and the third contact portion 41C have a center in the front-rear direction that coincides with each other. Therefore, the contact portion 41 is located at a center in the up-down direction of the cutter carriage 4A.

[0104] As shown in Figure 4 , the right wall 40R of the cutter carriage 4A includes a first portion 421 and a second portion 422. The first portion 421 and the second portion 422 are portions configured to clamp a cutting target 99 in cooperation with the cutter blade 30. The first portion 421 and the second portion 422 are positioned offset from each other in the up-down direction. Specifically, the first portion 421 is located below the second portion 422.

[0105] The first portion 421 and the second portion 422 have lengths in the front-rear direction that are equal to each other, and equal to a length L40 of the cutter carriage 4A in the front-rear direction. As shown in Figure 8 and Figure 10 , the length L40 of the cutter carriage 4A is smaller than a length L30 of the cutter blade 30 in the front-rear direction.

[0106] When the cutter carriage 4A is located at the half-cutting position (see Figure 8 ), or when the cutter carriage 4A is located at the full-cutting position (see Figure 10In any case of the cutting position, the front end portion of the cutter blade 30 is positioned further forward than the front end of the cutter carriage 4A, and the rear end portion of the cutter blade 30 is positioned further rearward than the rear end of the cutter carriage 4A. That is, when the cutter carriage 4A is positioned at the half-cutting position and when the cutter carriage 4A is positioned at the full-cutting position, the front end portion and the rear end portion of the cutter blade 30 are positioned further outward than the front end and the rear end of the cutter carriage 4A, respectively.

[0107] The first portion 421 is made of resin, and has a flat surface. The second portion 422 is made of metal, and includes a flat surface portion 422A and a pair of protruding portions 422B. The flat surface portion 422A has a flat surface. The pair of protruding portions 422B are provided at respective end portions of the flat surface portion 422A in the front-rear direction to protrude further rightward than the flat surface portion 422A. The pair of protruding portions 422B are positioned apart from each other so that the flat surface portion 422A is located between the protruding portions 422B in the front-rear direction.

[0108] The protruding length of each of the protruding portions 422B in the left-right direction with respect to the flat surface portion 422A is approximately 50 μm. The minimum distance in the front-rear direction between the protruding portions 422B is greater than the length of the cutting target 99 in the front-rear direction, i.e., the width direction length of the cutting target 99.

[0109] The shaft 27 extending in the up-down direction is fixed to the inner portion of the housing 1A, and as shown in Figures 4 to 7 the pivot member 4B is pivotally movable by the shaft 27. The pivot member 4B includes a base portion 46, a tubular portion 47, a holding member 48, and a spring 49.

[0110] The base portion 46 is functionally used to support the tubular portion 47 and the holding member 48, which will be described later. As shown particularly in Figure 5 and Figure 6 the base portion 46 includes a base plate 460, a first abutting plate 46A, and a second abutting plate 46B. The base plate 460 extends perpendicular to the front-rear direction, and is positioned further forward than the cutter carriage 4A.

[0111] The first and second abutting plates 46A and 46B extend rearward from the rear surface of the base plate 460, and also extend perpendicular to the up-down direction. The first abutting plate 46A is provided on the lower end portion of the base plate 460, and extends in the left-right direction over the entire length of the base plate 460 in the left-right direction. The first abutting plate 46A is positioned further upward than the upper wall 40U of the cutter carriage 4A.

[0112] The second abutting plate 46B is provided on the upper end portion of the base plate 460, and extends rightward from the left end of the base plate 460. The second abutting plate 46B has a right end portion provided with a hook 461.

[0113] A tubular portion 47 is provided on the left end of the base 46 and extends rearward from the rear surface of the substrate 460. A shaft 27 is inserted through a hole formed in the substrate 460 and the internal space of the tubular portion 47. With this configuration, the pivoting member 4B can pivotally move about the shaft 27.

[0114] Spring 49 is a torsion spring having a coil portion disposed on the tubular portion 47 and an end held by a hook 461 of the base 46. When viewed from the rear side of the pivot member 4B, spring 49 pushes the pivot member 4B in a clockwise direction. The pushing force of spring 49 is less than the pushing force of the bracket lever spring (not shown) that pushes the cutter bracket lever 6 in a clockwise direction C61.

[0115] The retaining member 48 has a generally solid cylindrical shape and extends rearward from the base plate 460 of the base 46. During the process of attaching the cutter holder 4A to the support 26, the cutter holder 4A moves forward relative to the retaining member 48, such that the retaining member 48 is inserted from the front side of the insertion portion 410 into the insertion portion 410, which is surrounded by the first contact portion 41A, the second contact portion 41B, the third contact portion 41C, and the upper wall 40U. The retaining member 48 contacts a portion of the inner wall of the insertion portion 410.

[0116] Incidentally, the contact portion 41 is located at the center of the cutter bracket 4A in the vertical direction, as described above. Therefore, the contact portion 41 contacts the retaining member 48 at the center of the cutter bracket 4A in the front-rear direction.

[0117] As in Figure 6 and Figure 9 As shown, with the cutter bracket lever 6 in the full-cutting standby position, the left end of the arm 63C of the cutter bracket lever 6 is positioned above and abuts against the upper surface of the first abutment plate 46A. This abutment of the arm 63C against the first abutment plate 46A restricts the clockwise pivoting movement of the pivoting member 4B caused by the pushing force of the spring 49.

[0118] In this state, the member 48 remains in contact with the contact portion 41 of the upper wall 40U and the cutter bracket 4A, and the cutter bracket 4A is pressed downward. Meanwhile, as in Figure 13 and Figure 14 As shown, the third protrusion 403 is pressed against the support portion 26, thereby positioning the cutter bracket 4A in the half-cutting position. Furthermore, in this state, the second portion 422 of the cutter bracket 4A is as shown in... Figure 4 and Figure 8 The image shown is located to the left of and facing the cutter blade 30.

[0119] In another aspect, during movement of the cutter holder lever 6 from the full-cut standby position to the full-cut operation position, the left end portion of the arm portion 63C of the extension portion 63 moves upward so that the arm portion 63C is separated from the first abutting plate 46A as shown in Figure 11 With the arm portion 63C separated upward, the pivot member 4B is pivotally moved in the clockwise direction by the urging force of the spring 49 to cause the holding member 48 to move upward with the pivotal movement of the pivot member 4B.

[0120] Correspondingly, the contact portion 41 of the cutter holder 4A receives the pressing force applied upward from the holding member 48 so that the cutter holder 4A is pivotally moved until the fourth protrusion 404 comes into abutment with the support portion 26. As a result, the cutter holder 4A is moved from the half-cut position to the full-cut position. Further, as shown in Figure 10 In the state where the cutter holder 4A is at the full-cut position, the first portion 421 of the cutter holder 4A is located leftward of the cutter blade 30 and faces the cutter blade 30 as shown in

[0121] As shown in Figure 16 The moving direction of the cutter holder 4A from the half-cut position to the full-cut position will be referred to as a "first moving direction Y11". In this case, the support portion 26 is relatively moved in a "second moving direction Y12" opposite to the first moving direction Y11 with respect to the cutter holder 4A. Further, the moving direction in which the cutter blade 30 is moved together with the cutter holder 32 will be referred to as a "cutter blade moving direction Y13".

[0122] The first moving direction Y11 is a direction obliquely leftward and upward. The second moving direction Y12 is a direction obliquely rightward and downward. The cutter blade moving direction Y13 coincides with the left-right direction. That is, both the first moving direction Y11 and the second moving direction Y12 cross the cutter blade moving direction Y13. Further, during movement of the cutter holder 4A in the first moving direction Y11 from the half-cut position to the full-cut position, the support portion 26 is relatively moved in the second moving direction Y12 with respect to the cutter holder 4A so that the right lower corner portion of the support portion 26 is pressed against the right wall 40R and the lower wall 40S of the cutter holder 4A.

[0123] As shown in Figure 17 In the state where the holding member 48 is inserted into the insertion portion 410, the upper wall 40U of the cutter holder 4A is located below the holding member 48 to face the holding member 48. The upper wall 40U includes the first inclined portion 44A, the first load portion 44B, and the first contact portion 44C.

[0124] In the upper wall 40U, the first inclined portion 44A is a portion located in front of the insertion portion 410, the first contact portion 44C constitutes a portion located in rear of the insertion portion 410, and the first load portion 44B is located in rear of the first inclined portion 44A and in front of the first contact portion 44C. The first load portion 44B is aligned with the insertion portion 410 and constitutes the insertion portion 410. That is, the first inclined portion 44A, the first load portion 44B, and the first contact portion 44C are arranged in this order in the rear direction.

[0125] The first inclined portion 44A is inclined with respect to the front-rear direction. As shown in detail in Figure 17 the first inclined portion 44A has a front end 441 and a rear end 442 adjacent to the first load portion 44B. The first inclined portion 44A is inclined obliquely forward and downward as it extends from the rear end 442 to the front end 441. In other words, the first inclined portion 44A is inclined forward such that the front end 441 is positioned further downward than the rear end 442.

[0126] Irrespective of the relative positions between the cutter holder 4A and the holding member 48, the first inclined portion 44A and the holding member 48 are always spaced apart from each other in the vertical direction. With this configuration, even when the holding member 48 moves, no load is applied from the holding member 48 on the first inclined portion 44A.

[0127] The first load portion 44B protrudes upward such that the first load portion 44B is positioned further upward than the first inclined portion 44A. In a state where the cutter holder 4A is at the half-cut position, the first load portion 44B is in contact with the second load portion 45B (described later) of the holding member 48. The first load portion 44B receives a load directly from the holding member 48 to hold the cutter holder 4A at the half-cut position.

[0128] The first load portion 44B has a front end 443 adjacent to the first inclined portion 44A and a rear end 444 adjacent to the first contact portion 44C. The first load portion 44B is inclined obliquely rearward and downward as it extends from the front end 443 to the rear end 444. In other words, the first load portion 44B is inclined rearward such that the rear end 444 is positioned further downward than the front end 443.

[0129] The first contact portion 44C is positioned further downward than the first load portion 44B and is in contact with the second contact portion 45C (described later) of the holding member 48 from below.

[0130] The holding member 48 includes a second inclined portion 45A, a second load portion 45B, and a second contact portion 45C, which are portions located above the cutter holder 4A to face the cutter holder 4A in a state where the holding member 48 is inserted into the insertion portion 410.

[0131] In the holding member 48, the second inclined portion 45A is a portion located in front of the insertion portion 410, the second contact portion 45C constitutes a portion located in rear of the insertion portion 410, and the second load portion 45B is located in rear of the second inclined portion 45A and in front of the second contact portion 45C. The second load portion 45B is aligned with the insertion portion 410 in the up-and-down direction, and is located inside the insertion portion 410. That is, the second inclined portion 45A, the second load portion 45B, and the second contact portion 45C are arranged in this order in the rearward direction.

[0132] The second inclined portion 45A has a portion located above the first inclined portion 44A, and faces the first inclined portion 44A. The second inclined portion 45A is inclined with respect to the front-and-rear direction. Specifically, the second inclined portion 45A has a front end 451 and a rear end 452 adjacent to the second load portion 45B. The second inclined portion 45A is inclined obliquely forward and downward as it extends from the rear end 452 to the front end 451. In other words, the second inclined portion 45A is inclined forward such that the front end 451 is positioned further downward than the rear end 452.

[0133] Irrespective of the relative position between the cutter holder 4A and the holding member 48, the second inclined portion 45A and the first inclined portion 44A of the cutter holder 4A are always spaced apart from each other in the up-and-down direction. Accordingly, even when the holding member 48 moves, the second inclined portion 45A does not apply a load to the cutter holder 4A.

[0134] In a state where the cutter holder 4A is at the half-cut position, the second load portion 45B is in contact with the first load portion 44B of the cutter holder 4A. The second load portion 45B directly applies a load to the cutter holder 4A to hold the cutter holder 4A at the half-cut position.

[0135] The second load portion 45B has a front end 453 adjacent to the second inclined portion 45A and a rear end 454 adjacent to the second contact portion 45C. The second load portion 45B is inclined obliquely rearward and downward as it extends from the front end 453 to the rear end 454. In other words, the second load portion 45B is inclined rearward such that the rear end 454 is positioned further downward than the front end 453.

[0136] The second contact portion 45C protrudes downward to be positioned further downward than the second load portion 45B, and contacts the first contact portion 44C of the cutter holder 4A from above.

[0137] The lid 1D has an inner surface (i.e., a front surface) provided with a protrusion 10F. In a state in which the lid 1D closes the cartridge receiving portion 2, the protrusion 10F protrudes forward toward the cutter cradle 4A attached to the support portion 26. The protrusion 10F is configured to prevent the cutter cradle 4A from being unintentionally detached from the support portion 26 of the cartridge receiving portion 2. The protrusion 10F has a protruding end (i.e., a front end) positioned to be away from the cutter cradle 4A in the front-rear direction to form a gap between the protrusion 10F and the cutter cradle 4A.

[0138] [Print operation]

[0139] Next, a print operation performed in the printing device 1 according to the first embodiment will be described. In a state in which the lid 1D opens the cartridge receiving portion 2 (a state shown in FIG. 1A), the platen holder 23 is at a distal position. When a user attaches the cartridge 9 to the cartridge receiving portion 2, the ribbon take-up shaft 22B is inserted into the ribbon take-up spool 96D, and at the same time, the tape drive shaft 22A is inserted into the tape drive roller 91, and the head holder 21 is inserted into the head opening 94A. In this state, the width direction of each of the clear film tape 99A, the ink ribbon 99C, and the double-sided tape 99B is parallel to the front-rear direction. Figure 2

[0140] Then, with the closing movement of the lid 1D, the platen holder 23 is pivotally moved from the distal position to a proximal position. As a result, the platen roller 23B presses the stacked ink ribbon 99C and clear film tape 99A against the print head 21A. The transport roller 23C presses the stacked double-sided tape 99B and clear film tape 99A against the tape drive roller 91.

[0141] In response to the input of the print instruction of the user to the operation portion 1B, the drive motor is driven to rotate the tape drive shaft 22A, the platen roller 23B, and the ribbon take-up shaft 22B. The tape drive roller 91 rotates together with the rotation of the tape drive shaft 22A, and the transport roller 23C rotates with the rotation of the tape drive roller 91. Thus, the double-sided tape 99B, the clear film tape 99A, and the ink ribbon 99C are transported in the printing device 1.

[0142] Specifically, the double-sided tape 99B is paid out from the second tape roll 97B, the clear film tape 99A is paid out from the first tape roll 97A, and the ink ribbon 99C is paid out from the ribbon roll 97C. The clear film tape 99A and the ink ribbon 99C are ejected through the first tape guide 95A and transported toward the printing position due to the rotation of the drive motor.

[0143] ​In the printing device 1, the print head 21A generates heat to allow ink contained in the ink ribbon 99C to be transferred to the transparent film ribbon 99A, whereby a character is printed on the transparent film ribbon 99A at a printing position. By rotation of the platen roller 23B and the ribbon take-up shaft 22B, the transparent film ribbon 99A and the used ink ribbon 99C are conveyed toward the second ribbon guide 95B.

[0144] As the ink ribbon 99C is separated from the transparent film ribbon 99A at the separation position, ink contained in the ink ribbon 99C is released from the ink ribbon 99C. The used ink ribbon 99C that has moved past the separation position is taken up as the ribbon take-up roll 97D by rotation of the ribbon take-up shaft 22B. The printed transparent film ribbon 99A that has moved past the separation position is guided to the second ribbon guide 95B by rotation of the convey roller 23C and the ribbon drive roller 91.

[0145] At a position between the ribbon drive roller 91 and the convey roller 23C, one surface of the double-sided adhesive tape 99B and the transparent film ribbon 99A that has moved past the second ribbon guide 95B are bonded together to provide a cut target 99. The provided cut target 99 is conveyed toward the ejection section 93. The cut target 99 that moves past the ejection section 93 passes through the cutting device IE, and is discharged toward the upper portion of the housing 1A. Then, the drive motor and the print head 21A are stopped, and the printing operation is terminated. When a new printing instruction is input by the user through the operation section IB, a subsequent printing operation can be repeatedly performed in this manner.

[0146] [Half-cutting operation]

[0147] A half-cutting operation will next be described as to how it is performed in the cutting device IE. For example, the half-cutting operation is performed each time a printing operation is performed. To perform the half-cutting operation, the user only operates the cutter lever 5 to move the cutter lever 5 from the half-cut standby position (see Figure 4 and Figure 6 ) to the half-cutting operation position (see Figure 8 and Figure 9 ) in the direction indicated by the arrow C52 against the urging force of a cutter lever spring (not shown).

[0148] By this operation, the entry portion 52A of the cutter lever 5 enters the notched hole 31A of the box member 31 of the cutter portion 10B to come into contact with the cutter holder 32, whereby the cutter holder 32 is moved against the urging force of a cutter spring (not shown). With movement of the cutter holder 32, the cutter blade 30 is also moved to the left from the retracted position (see Figure 4 ) to the cutting position (see Figure 8 ).

[0149] Note that when only the cutter lever 5 is operated by the user, the cutter carriage lever 6 is not moved and is maintained at its full-cut standby position. Accordingly, as shown in Figure 14 , the cutter carriage 4A is maintained at the half-cut position. In this state, as shown in Figure 8 and Figure 14 , the second portion 422 of the cutter carriage 4A faces the cutter blade 30 at a position left of the cutter blade 30.

[0150] The cutter blade 30, which moves together with the cutter holder 32, clamps the cutting target 99 in cooperation with the second portion 422. The cutter blade 30 presses the cutting target 99 to the left, and comes into contact with the pair of protruding portions 422B of the second portion 422. Since the cutting edge of the cutter blade 30 cannot reach the flat surface portion 422A of the second portion 422, the cutting target 99 is partially cut in its thickness direction. In this way, by the cooperation of the cutter blade 30 and the second portion 422 of the cutter carriage 4A, a half-cut operation is performed with respect to the cutting target 99.

[0151] After the half-cut operation is completed with respect to the cutting target 99, the user releases the operation of the cutter lever 5 to allow the cutter lever 5 to move from the half-cut operation position to the half-cut standby position in the direction indicated by the arrow C51 (see Figure 4 ) due to the urging force of the cutter lever spring. The entry portion 52A of the cutter lever 5 is moved out of the notched hole 31A of the box member 31 of the cutter portion 10B. Accordingly, the cutter holder 32 is moved by the urging force of the cutter spring to move the cutter blade 30 from the cutting position (see Figure 8 ) to the retracted position (see Figure 4 ). The cutter blade 30 is thus accommodated in the box member 31.

[0152] [Full-cut operation]

[0153] The procedure of the full-cut operation will be described next. The full-cut operation is performed, for example, after the printing operation and the half-cut operation corresponding thereto are repeatedly performed. To perform the full-cut operation, only the cutter carriage lever 6 is operated by the user to move the cutter carriage lever 6 from the full-cut standby position (see Figures 4 to 9 ) to the full-cut operation position (see Figure 10 and Figure 11 ) in the direction indicated by the arrow C62 against the urging force of the cutter carriage lever spring (not shown).

[0154] With the movement of the cutter carriage lever 6, the pivot member 4B also pivotally moves due to the urging force of the spring 49. In response to the movement of the holding member 48, a load is applied on the cutter carriage 4A, whereby the cutter carriage 4A moves from the half-cut position (seeFigure 13 ) to a full cutting position (see Figure 15 ). That is, the cutter holder lever 6 is indirectly in contact with the cutter holder 4A through the pivot member 4B for moving the cutter holder 4A from the half cutting position to the full cutting position. At the full cutting position of the cutter holder 4A, the first portion 421 of the cutter holder 4A faces the cutter blade 30 of the cutter holder 32 at a position left of the cutter blade 30.

[0155] Further, with the movement of the cutter holder lever 6, the contact portion 62 of the cutter holder lever 6 comes into contact with the protruding portion 52 of the cutter lever 5 to move the cutter lever 5 from the half cutting standby position to the half cutting operation position against the pressing force of the cutter lever spring. That is, due to the user operation of only the cutter holder lever 6, the cutter lever 5 is moved in the linked relationship with the cutter holder lever 6 through the linkage portion 10D.

[0156] At this time, the protruding portion 52 of the cutter lever 5 enters the notch hole 31A of the box member 31 of the cutter portion 10B to move the cutter holder 32. Accordingly, the cutter holder 32 moves the cutter blade 30 from the retracted position (see Figure 4 ) to the cutting position (see Figure 10 ).

[0157] The cutter blade 30 that has moved together with the cutter holder 32 clamps the cutting target 99 in cooperation with the first portion 421 of the cutter holder 4A. The cutting edge of the cutter blade 30 presses the cutting target 99 to the left and comes into contact with the first portion 421. Because the cutting edge reaches the first portion 421, the cutting target 99 is completely cut in the thickness direction thereof and is divided into two portions. The full cutting operation with respect to the cutting target 99 is performed in this way by the cooperation of the cutter blade 30 and the first portion 421 of the cutter holder 4A.

[0158] After the full cutting operation with respect to the cutting target 99 is terminated, the user operation of the cutter holder lever 6 is released. Due to the pressing force of the cutter holder lever spring, the cutter holder lever 6 is moved from the full cutting operation position back to the full cutting standby position in the direction indicated by an arrow C61 (see Figure 4 ). Further, with the movement of the cutter holder lever 6, the pivot member 4B is pivotally moved back against the pressing force of the spring 49 to move the cutter holder 4A from the full cutting position (see Figure 15 ) to the half cutting position (see Figure 13 ).

[0159] Further, with the movement of the cutter holder lever 6 to the full-cut standby position, the contact portion 62 of the cutter holder lever 6 is separated from the protrusion portion 52 of the cutter lever 5. As a result, the cutter lever 5 is also moved from the half-cut operation position to the half-cut standby position by the urging force of the cutter lever spring, so that the entry portion 52A of the cutter lever 5 is withdrawn from the notch hole 31A of the box member 31 of the cutter portion 10B. Therefore, the cutter holder 32 is moved to the right by the urging force of the cutter spring, to move the cutter blade 30 from the cutting position (see Figure 10 ) to the retracted position (see Figure 4 ). The cutter blade 30 is thus accommodated in the box member 31.

[0160] [Advantageous Effects in Embodiments]

[0161] In the printing device 1, when only the cutter lever 5 is operated by the user, the cutter blade 30, which has been moved together with the cutter holder 32 due to the movement of the cutter lever 5, performs a half-cut operation with the cutter holder 4A located at the half-cut position with respect to the cutting target 99 in cooperation with each other (see Figure 8 and Figure 14 ).

[0162] On the other hand, when only the cutter holder lever 6 is operated by the user, the cutter blade 30, which has been moved together with the cutter holder 32 due to the movement of the cutter lever 5, performs a full-cut operation with the cutter holder 4A, which has been moved to the full-cut position due to the movement of the cutter holder lever 6, with respect to the cutting target 99 in cooperation with each other (see Figure 10 and Figure 15 ). In this way, it is possible to perform the full-cut operation and the half-cut operation with respect to the cutting target 99 by the user operations of the cutter holder lever 6 and the cutter lever 5.

[0163] Thus, according to the printing device 1, it is possible to selectively perform the full-cut operation and the half-cut operation with respect to the cutting target 99 without providing a motor for moving the cutter blade 30 in the printing device 1. Therefore, the weight of the printing device 1 can be reduced compared to the case where the motor is provided in the printing device.

[0164] In the printing device 1, the cutter lever 5 is positioned further forward than the cutter carriage lever 6. Therefore, a user first operates the cutter lever 5 located in front of the cutter carriage lever 6 to perform a half-cut operation with respect to the cutting target 99, and then operates the cutter carriage lever 6 located behind the cutter lever 5 to perform a full-cut operation with respect to the cutting target 99. That is, by operating the cutter lever 5 and the cutter carriage lever 6 in this order in the rearward direction, the user is able to perform a half-cut operation and thereafter a full-cut operation in this order. Accordingly, the user is able to intuitively distinguish the operations of the cutter lever 5 and the cutter carriage lever 6.

[0165] In the printing device 1, when a user operation only on the cutter lever 5 is performed, the cutter lever 5 and the cutter carriage lever 6 do not move in a linked relationship with each other. On the other hand, when a user operation only on the cutter carriage lever 6 is performed, the cutter lever 5 and the cutter carriage lever 6 move in a linked relationship with each other with the linkage portion 10D.

[0166] Therefore, a full-cut operation with respect to the cutting target 99 can be performed by the cooperation of the cutter carriage 4A that has moved to the full-cut position due to the movement of the cutter carriage lever 6 and the cutter blade 30 that has moved due to the movement of the cutter lever 5 moved by the linkage portion 10D. As a result, a full-cut operation can be performed only by operating the cutter carriage lever 6 without the need to operate the cutter lever 5 and the cutter carriage lever 6.

[0167] When the cutter carriage 4A is located at the half-cut position (see Figure 8 ), and when the cutter carriage 4A is located at the full-cut position (see Figure 10 ), both end portions of the cutter blade 30 in the front-rear direction are respectively positioned further outward than both end portions of the cutter carriage 4A in the front-rear direction. Accordingly, even in the case where the end portion of the cutting edge of the cutter blade 30 in the lengthwise direction (front-rear direction) is distorted, the cutting target 99 can be properly cut by the cooperation of the cutter blade 30 and the cutter carriage 4A.

[0168] When the cutter carriage 4A moves in the first movement direction Y11 from the half-cut position to the full-cut position, the support portion 26 moves in the second movement direction Y12 with respect to the cutter carriage 4A so that the right lower corner portion of the support portion 26 is pressed against the right wall 40R and the lower wall 40S of the cutter carriage 4A. With this configuration, when a cutting operation is performed with respect to the cutting target 99 in the printing device 1, displacement of the cutter carriage 4A due to a force applied from the cutter blade 30 to the cutter carriage 4A can be restricted with the support portion 26. Accordingly, the printing device 1 is able to properly perform a cutting operation with respect to the cutting target 99.

[0169] When receiving the pressing force from the holding member 48 at the contact portion 41, the cutter holder 4A is pivotally movable. Because the contact portion 41 is located at the center of the cutter holder 4A in the front-rear direction, it is less likely to occur that the cutter holder 4A is twisted in the direction in which the cutting edge of the cutter blade 30 extends due to the pivotal movement of the cutter holder 4A when the force is applied from the holding member 48 to the cutter holder 4A. Accordingly, the printing device 1 is able to perform an appropriate cutting operation with respect to the cutting target 99.

[0170] In the cutting device IE, the first inclined portion 44A of the upper wall 40U of the cutter holder 4A is inclined downward in the forward direction as extending from the rear end 442 to the front end 441. Further, the second inclined portion 45A of the holding member 48 is inclined downward in the forward direction as extending from the rear end 452 to the front end 451. With this configuration, when the cutter holder 4A is moved forward during attachment of the cutter holder 4A to the support portion 26, the holding member 48 is able to be easily inserted into the insertion portion 410 of the cutter holder 4A. Thus, it is possible to facilitate the process of attaching the cutter holder 4A with respect to the support portion 26.

[0171] The first load portion 44B of the upper wall 40U of the cutter holder 4A is inclined downward in the rearward direction as extending from the front end 443 to the rear end 444. Further, the second load portion 45B of the holding member 48 is inclined downward in the rearward direction as extending from the front end 453 to the rear end 454.

[0172] With this configuration, in a state where the holding member 48 is pressed against the upper wall 40U of the cutter holder 4A from above, a force directed in the forward direction is applied to the cutter holder 4A. The force is directed in a direction opposite to a direction in which the insertion portion 410 of the cutter holder 4A is detached from the holding member 48 (i.e., the rearward direction). Accordingly, with the first load portion 44B and the second load portion 45B, it is possible to suppress the holding member 48 from being unintentionally detached from the insertion portion 410.

[0173] In a case where the first inclined portion 44A of the cutter holder 4A and the second inclined portion 45A of the holding member 48 are in contact with each other and a load is applied from the holding member 48 to the cutter holder 4A, a force directed in the rearward direction to release the holding member 48 from the insertion portion 410 can be applied to the cutter holder 4A, which leads to an adverse situation (i.e., the holding member 48 is unintentionally detached from the insertion portion 410).

[0174] However, according to the printing device 1, the first inclined portion 44A and the second inclined portion 45A are always spaced apart from each other in the up-down direction regardless of the positional relationship between the cutter carriage 4A and the holding member 48. Accordingly, it is possible to restrict the holding member 48 from being unintentionally detached from the insertion portion 410.

[0175] In a state where the cutter carriage 4A is located at the half-cutting position, the first load portion 44B of the cutter carriage 4A and the second load portion 45B of the holding member 48 are in contact with each other. In this state, when a load is applied from the holding member 48 to the cutter carriage 4A, a force directed in the forward direction (i.e., the direction in which the insertion portion 410 is attached to the holding member 48) is applied from the holding member 48 to the cutter carriage 4A, thereby ensuring that the holding member 48 is inserted into the insertion portion 410. Accordingly, with the first load portion 44B and the second load portion 45B, it is possible to restrict the insertion portion 410 from being released from the holding member 48.

[0176] The cover 1D includes a protrusion 10F for preventing the cutter carriage 4A from being detached from the support portion 26. Further, when the cover 1D closes the cartridge receiving portion 2, a gap is formed between the protrusion 10F and the cutter carriage 4A. Therefore, the cutter carriage 4A can smoothly move between the half-cutting position and the full-cutting position without mechanical interference between the cutter carriage 4A and the protrusion 10F.

[0177] [Variations]

[0178] Although the description has been made with reference to the embodiments in detail, it will be apparent to those skilled in the art that the present disclosure is not limited to the above-described embodiments, and various changes and modifications can be made thereto.

[0179] For example, the cutting device 1E can not be provided in the printing device 1, but can be provided in another device that will cut the cutting target 99. Further, the cutting device 1E can not be provided in a device, and can be a separate cutting device for cutting the cutting target 99.

[0180] The display portion 1C and the cartridge receiving portion 2 can be located at the same side of the housing 1A. That is, the display portion 1C and the cartridge receiving portion 2 can be provided close to each other in the front-back direction. In this case, the cutter lever 5 can be located at the side where the display portion 1C and the cartridge receiving portion 2 are located. The cutter lever 5 can be positioned further rearward than the cutter carriage lever 6.

[0181] In the printing device 1, the link portion 10D (the combination of the protrusion 52 and the contact portion 62) can be dispensed with. In the latter case, the full-cutting operation with respect to the cutting target 99 can be performed by the user's operation of the cutter lever 5 and the cutter carriage lever 6.

[0182] The length L30 of the cutter blade 30 in the front-rear direction can be equal to the length L40 of the cutter holder 4A in the front-rear direction. In the latter case, the front end and the rear end of the cutter blade 30 in the front-rear direction can be aligned with the front end and the rear end of the cutter holder 4A in the front-rear direction, respectively.

[0183] The direction in which the cutter holder 4A moves from the half-cutting position to the full-cutting position can coincide with the upward direction. In this case, the support portion 26 can be pressed against only the lower wall 40S, and can not be pressed against the right wall 40R. Further, in this case, a leftward pushing pressure can be applied to the cutter holder 4A that has moved from the half-cutting position to the full-cutting position. Due to the leftward pushing pressure, the support portion 26 can be pressed against the right wall 40R.

[0184] The contact portion 41 can be provided over the entire length of the cutter holder 4A in the front-rear direction. Alternatively, the contact portion 41 can be provided on each end portion of the cutter holder 4A in the front-rear direction, and the contact portion 41 can not be provided at the center of the cutter holder 4A in the front-rear direction. The contact portion 41 can have a configuration that allows the contact portion 41 to engage with the holding member 48. In the latter case, a state in which the contact portion 41 is in contact with the holding member 48 can be maintained.

[0185] At least one of the first inclined portion 44A of the cutter holder 4A and the second inclined portion 45A of the holding member 48 can extend parallel to the front-rear direction. In particular, the second inclined portion 45A of the holding member 48 can extend parallel to the front-rear direction, while the first inclined portion 44A of the cutter holder 4A is inclined downward in the forward direction. Further, at least one of the first load portion 44B of the cutter holder 4A and the second load portion 45B of the holding member 48 can extend parallel to the front-rear direction.

[0186] Further, the first inclined portion 44A of the cutter holder 4A and the second inclined portion 45A of the holding member 48 can be in contact with each other when the cutter holder 4A is at the half-cutting position. Further, the first load portion 44B of the cutter holder 4A and the second load portion 45B of the holding member 48 can be separated from each other when the cutter holder 4A is at the half-cutting position.

[0187] The protruding end of the protruding portion 10F of the cover 1D can be in contact with the cutter holder 4A. Further, the cover 1D can not include the protruding portion 10F.

[0188] Although the combination of the transparent film tape 99A and the double-sided tape 99B is employed as an example of the cutting target 99 in the above-described embodiment, other objects can also be the cutting target 99. For example, a print paper, a label, other kinds of tapes, tubes, and the like can be used as the cutting target 99, and the cutting operation can be performed with the cutting device IE with respect to these objects.
