The cutter lever spring urges the cutter lever 5 in a clockwise direction indicated by an arrow C51 in FIG. 4 as viewed from a rear side of the cutter lever 5. The most urged position of the cutter lever 5 in the clockwise direction C51 due to an urging force of the cutter lever spring will be referred to as “half-cutting standby position”. When the cutter lever 5 is not operated by the user, the cutter lever 5 is urged by the cutter lever spring to be positioned at the half-cutting standby position. Accordingly, FIGS. 4 to 7 illustrate the cutter lever 5 at the half-cutting standby position.

On the other hand, in response to a user operation to the operation portion 51 of the cutter lever 5, the cutter lever 5 is pivotally moved in a direction opposite the direction C51, i.e., in a counterclockwise direction indicated by an arrow C52 against the urging force of the cutter lever spring as illustrated in FIG. 8. The most moved position of the cutter lever 5 in the counterclockwise direction C52 will be referred to as “half-cutting operation position.”

As illustrated in FIGS. 4 through 7, the cutter cradle lever 6 includes an operation portion 61, a contacting portion 62 (see FIGS. 13 through 15), an extending portion 63, and a cutter cradle lever spring (not illustrated). The operation portion 61 is a portion that can be operated by the user. The operation portion 61 is positioned rearward of the operation portion 51 of the cutter lever 5. Similar to the operation portion 51 of the cutter lever 5, the operation portion 61 protrudes outward (rightward and upward) through the opening 11 of the housing 1A. The operation portion 61 has a shape substantially coincident with that of the operation portion 51 in a plan view.

The contacting portion 62 is provided at a front surface of the operation portion 61 to protrude frontward therefrom. The contacting portion 62 can make contact with the protruding portion 52 of the cutter lever 5. In the following description, a combination of the protruding portion 52 and the contacting portion 62 will be occasionally referred to as “interlocking portion 10D”.

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

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 frontward from a front surface of the disc portion 63A through the interior space of the sleeve portion 50 of the cutter lever 5. The connecting portion 63B has a front end portion protruding further frontward than the sleeve portion 50 of the cutter lever 5. The through-hole of the connecting portion 63B is in communication with the hole of the disc portion 63A.

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

The cutter cradle lever spring (not illustrated) is a torsion spring provided over the lever shaft 100. The cutter cradle lever spring urges the cutter cradle lever 6 in a clockwise direction as indicated by an arrow C61 in FIGS. 4 and 8 as viewed from a rear side of the cutter cradle lever 6. The most urged position of the cutter cradle lever 6 in the clockwise direction C61 because of the urging force of the cutter cradle lever spring will be referred to as “full-cutting standby position”. When the cutter cradle lever 6 is not operated by the user, the cutter cradle lever 6 is urged by the cutter cradle lever spring and is positioned at the full-cutting standby position. Accordingly, FIGS. 4 to 7 illustrate the cutter cradle lever 6 positioned at the full-cutting standby position.

On the other hand, as illustrated in FIG. 10, in response to a user operation to the operation portion 61 of the cutter cradle lever 6, the cutter cradle lever 6 is pivotally moved in a direction opposite the direction C61, i.e., in a counterclockwise direction indicated by an arrow C62 against the urging force of the cutter cradle lever spring. The most moved position of the cutter cradle lever 6 in the counterclockwise direction C62 will be referred to as “full-cutting operation position”.

Note that, when the operation portion 61 of the cutter cradle lever 6 is operated by the user, the contacting portion 62 of the cutter cradle lever 6 is brought 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 the application of the force to the cutter lever 5, the cutter lever 5 is pivotally moved in the direction C52 in interlocking relation to the pivotal movement of the cutter cradle lever 6.

That is, movement of the cutter lever 5 from the half-cutting standby position to the half-cutting operation position is simultaneously performed in interlocking relation to the movement of the cutter cradle lever 6 from the full-cutting standby position to the full-cutting operation position by the user operation only to the cutter cradle lever 6, as illustrated in FIG. 10. On the other hand, when the cutter lever 5 is moved from the half-cutting standby position to the half-cutting operation position by the user operation only to the cutter lever 5, the movement of the cutter cradle lever 6 in accordance with the movement of the cutter lever 5 is not performed, and the cutter cradle lever 6 is maintained at the full-cutting standby position (see FIG. 8).

During a process of the movement of the cutter lever 5 from the half-cutting standby position (see FIG. 4) to the half-cutting operation position (see FIGS. 8 and 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 positioned inside the box member 31 receives a force applied from the entry portion 52A be moved leftward, thereby moving the cutter blade 30 leftward from the retracted position to the cutting position. As illustrated in FIGS. 8 and 10, the cutter blade 30 positioned at the cutting position protrudes leftward from the box member 31.

[Cradle Portion 10A]

The cradle portion 10A is configured to switch the cutting operation with respect to the cut target 99 in cooperation with the cutter portion 10B between the full-cutting operation and the half-cutting operation in accordance with the user operation to the lever portion 10C. As illustrated in FIGS. 4 through 7, the cradle portion 10A includes the cutter cradle 4A and a pivot member 4B.

The cutter cradle 4A has a generally rectangular-parallelepiped shape (a box-like shape) and elongated in the front-rear direction. The cutter cradle 4A is disposed leftward of the cutter holder 32 to face the same. As illustrated in FIG. 12, the cutter cradle 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 an upper end, a lower end, a rear end, a right end, and a left end of the cutter cradle 4A, respectively.

The right wall 40R extends perpendicularly to the left-right direction, and is positioned leftward of the cutter holder 32. The upper wall 40U is connected to an upper end of the right wall 40R. The lower wall 40S is connected to a lower end of the right wall 40R. The upper wall 40U and the lower wall 40S is positioned to extend away from the cutter holder 32, i.e., leftward.

The upper wall 40U extends perpendicularly to the up-down direction. The lower wall 40S is inclined relative to an imaginary plane perpendicular to the up-down direction. A gap between the upper wall 40U and the lower wall 40S is gradually increased as these walls extend rightward as illustrated in FIGS. 13 through 15. The cutter cradle 4A has a front end formed with a front opening 40A (see FIG. 12) that opens frontward. The front opening 40A is in communication with an internal space 40C (see FIGS. 13 through 15) defined by the walls 40U, 40S, 40B, 40R, and 40L.

A support portion 26 (see FIG. 12) having a plate-like shape is provided in the cassette receiving portion 2 of the housing 1A. The support portion 26 extends rearward from a bottom surface (a front inner surface) of the cassette receiving portion 2, and extends perpendicularly to the up-down direction. The cutter cradle 4A is movably supported by the support portion 26.

Specifically, the support portion 26 is inserted into the internal space 40C of the cutter cradle 4A through the front opening 40A so that the cutter cradle 4A is disposed over 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 approximately equal to that of the internal space 40C defined by the right and left walls 40R and 40L of the cutter cradle 4A (see FIGS. 13 through 15).

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

As illustrated in FIGS. 13 through 15, the cutter cradle 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 inward of the internal space 40C from a left end portion of the upper wall 40U. The second protrusion 402 protrudes inward of the internal space 40C from a left end portion of the lower wall 40S. A gap in the up-down direction between the first protrusion 401 and the second protrusion 402 is approximately equal to a thickness of the support portion 26 (i.e., a length in the up-down direction of the support portion 26). The first protrusion 401 and the second protrusion 402 nip a left end portion of the support portion 26 positioned within the internal space 40C in cooperation with each other in the up-down direction.

The third protrusion 403 protrudes inward of the internal space 40C from a right end portion of the upper wall 40U. The fourth protrusion 404 protrudes inward of the internal space 40C from a right end portion of the lower wall 40S. A 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.

As illustrated in FIGS. 13 and 14, a right end portion of the cutter cradle 4A is movable downward until the third protrusion 403 abuts against an upper surface of the support portion 26. Further, as illustrated in FIG. 15, the right end portion of the cutter cradle 4A is movable upward until the fourth protrusion 404 abuts against a lower surface of the support portion 26. Accordingly, the cutter cradle 4A is pivotally movable in the up-down direction about the left end portion of the cutter cradle 4A that nips the support portion 26 with the first and second protrusions 401 and 402.

FIGS. 13 and 14 illustrate “half-cutting position” of the cutter cradle 4A where the third protrusion 403 abut against the support portion 26 to place the cutter cradle 4A at a most pivotally moved position in the counterclockwise direction as viewed from the rear side of the cutter cradle 4A. On the other hand, FIG. 15 illustrates “full-cutting position” of the cutter cradle 4A where the cutter cradle 4A is at a most pivotally moved position in the clockwise direction as viewed from the read side thereof as a result of abutment of the fourth protrusion 404 against the support portion 26. Accordingly, the cutter cradle 4A is pivotally movable between the half-cutting position and the full-cutting position.

As illustrated in FIGS. 12 through 15, a contact portion 41 is provided on the upper wall 40U. The contact portion 41 includes a first contact part 41A, a second contact part 41B, and a third contact part 41C those having a plate-like shape. The first contact part 41A has a surface extending perpendicularly to the left-right direction and extends upward from the right end portion of the upper wall 40U. The first contact part 41A has a length in the front-rear direction approximately half a length in the front-rear direction of the upper wall 40U.

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

The third contact part 41C extends downward from a left end portion of the second contact part 41B, and is connected to the upper wall 40U. The third contact part 41C has a length in the front-rear direction equal to the length in the front-rear direction of the second contact part 41B. A portion surrounded by the first contact part 41A, the second contact part 41B, and the third contact part 41C will be referred to as “insertion portion 410”. The upper wall 40U, the first contact part 41A, the second contact part 41B, and the third contact part 41C have centers in the front-rear direction coincident with each other. Hence, the contact portion 41 is positioned at a center in the up-down direction of the cutter cradle 4A.

As illustrated in FIG. 4, the right wall 40R of the cutter cradle 4A includes a first part 421 and a second part 422. The first part 421 and the second part 422 are portions configured to nip the cut target 99 in cooperation with the cutter blade 30. The first part 421 and the second part 422 are positioned offset from each other in the up-down direction. Specifically, the first part 421 is positioned downward of the second part 422.

The first part 421 and the second part 422 have lengths in the front-rear direction equal to each other, and equal to a length L40 of the cutter cradle 4A in the front-rear direction. As illustrated in FIGS. 8 and 10, the length LAO of the cutter cradle 4A is smaller than a length L30 in the front-rear direction of the cutter blade 30.

In either cases where the cutter cradle 4A is positioned at the half-cutting position (see FIG. 8) or where the cutter cradle 4A is positioned at the full-cutting position (see FIG. 10), a front end portion of the cutter blade 30 is positioned further frontward than the front end of the cutter cradle 4A, and a rear end portion of the cutter blade 30 is positioned further rearward than the rear end of the cutter cradle 4A. That is, 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 cradle 4A, respectively, both when the cutter cradle 4A is positioned at the half-cutting position and when the cutter cradle 4A is positioned at the full-cutting position.

The first part 421 is made from resin, and has a flat surface. The second part 422 is made from metal, and includes a flat surface part 422A and a pair of protruding parts 422B. The flat surface part 422A has a flat surface. The pair of protruding parts 422B are provided at respective ends in the front-rear direction of the flat surface part 422A to protrude further rightward than the flat surface part 422A. The pair of protruding parts 422B are positioned away from each other so that the flat surface part 422A is positioned between the protruding parts 422B in the front-rear direction.

A protruding length in the left-right direction of each of the protruding parts 422B relative to the flat surface part 422A is approximately 50 μm. A minimum distance in the front-rear direction between the protruding parts 422B is greater than the length in the front-rear direction of the cut target 99, i.e., the widthwise length of the cut target 99.

A shaft 27 extending in the up-down direction is fixed to an interior portion of the housing 1A, and the pivot member 4B is pivotally movably supported by the shaft 27 as illustrated in FIGS. 4 through 7. The pivot member 4B includes a base portion 46, a tubular portion 47, a holding member 48, and a spring 49.

The base portion 46 functions to support both the tubular portion 47 and the holding member 48 those will be described later. The base portion 46 includes a base plate 460, a first abutment plate 46A, and a second abutment plate 46B as particularly illustrated in FIGS. 5 and 6. The base plate 460 extends perpendicular to the front-rear direction, and is positioned further frontward than the cutter cradle 4A.

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

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

The tubular portion 47 is provided on the left end portion of the base portion 46, and extends rearward from the rear surface of the base plate 460. The shaft 27 is inserted through a hole formed in the base plate 460 and an interior space of the tubular portion 47. With this configuration, the pivot member 4B is pivotally movable about the shaft 27.

The spring 49 is a torsion spring having a coil portion disposed over the tubular portion 47 and one end portion held by the hook 461 of the base portion 46. The spring 49 urges the pivot member 4B in a clockwise direction as viewed from the rear side of the pivot member 4B. An urging force of the spring 49 is smaller than the urging force of the cradle lever spring (not illustrated) that urges the cutter cradle lever 6 in the clockwise direction C61.

The holding member 48 has a substantially solid cylindrical shape, and extends rearward from the base plate 460 of the base portion 46. During a process of the attachment of the cutter cradle 4A to the support portion 26, the cutter cradle 4A is moved frontward relative to the holding member 48 so that the holding member 48 is inserted into the insertion portion 410 surrounded by the first contact part 41A, the second contact part 41B, the third contact part 41C, and the upper wall 40U from a front side of the insertion portion 410. The holding member 48 makes contact with a part of an inner wall of the insertion portion 410.

Incidentally, the contact portion 41 is positioned at the center in the up-down direction of the cutter cradle 4A as described above. Hence, the contact portion 41 makes contact with the holding member 48 at the center in the front-rear direction of the cutter cradle 4A.

As illustrated in FIGS. 6 and 9, in a state where the cutter cradle lever 6 is positioned at the full-cutting standby position, the left end portion of the arm portion 63C of the cutter cradle lever 6 is positioned upward of and in abutment against an upper surface of the first abutment plate 46A. With this abutment of the arm portion 63C against the first abutment plate 46A, the pivotal movement of the pivot member 4B in the clockwise direction because of the urging force of the spring 49 is restrained.

In this state, the holding member 48 is in contact with the upper wall 40U and the contact portion 41 of the cutter cradle 4A and presses the cutter cradle 4A downward. At the same time, as illustrated in FIGS. 13 and 14, the third protrusion 403 is pressed against the support portion 26, whereby the cutter cradle 4A is positioned at the half-cutting position. Further, in this state, the second part 422 of the cutter cradle 4A is positioned leftward of the cutter blade 30 and faces the cutter blade 30 as illustrated in FIGS. 4 and 8.

On the other hand, in the process of the movement of the cutter cradle lever 6 from the full-cutting standby position to the full-cutting operation position, the left end portion of the arm portion 63C of the extending portion 63 is moved upward so that the arm portion 63C is separated away from the first abutment plate 46A as illustrated in FIG. 11. As the arm portion 63C is 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 be moved upward in accordance with the pivotal movement of the pivot member 4B.

Accordingly, the contact portion 41 of the cutter cradle 4A receives an pressing force directed upward and applied from the holding member 48 so that the cutter cradle 4A is pivotally moved until the fourth protrusion 404 is brought into abutment against the support portion 26. As a result, the cutter cradle 4A is moved to the full-cutting position from the half-cutting position. Further, as illustrated in FIG. 10, in a state where the cutter cradle 4A is at the full-cutting position, the first part 421 of the cutter cradle 4A is positioned leftward of the cutter blade 30 and faces the cutter blade 30.

A moving direction in which the cutter cradle 4A is moved from the half-cutting position to the full-cutting position will be referred to as “first moving direction Y11” as illustrated in FIG. 16. In this case, the support portion 26 is relatively moved with respect to the cutter cradle 4A in “second moving direction Y12” opposite the first moving direction Y11. Further, a moving direction in which the cutter blade 30 is moved together with the movement of the cutter holder 32 will be referred to as a “cutter blade moving direction Y13”.

The first moving direction Y11 is a direction directed diagonally leftward and upward. The second moving direction Y12 is a direction directed diagonally rightward and downward. The cutter blade moving direction Y13 is coincident 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 the movement of the cutter cradle 4A from the half-cutting position to the full-cutting position in the first moving direction Y11, the support portion 26 is relatively moved in the second moving direction Y12 with respect to the cutter cradle 4A so that a right-lower corner portion of the support portion 26 is pressed against the right wall 40R and the lower wall 40S of the cutter cradle 4A.

As illustrated in FIG. 17, in a state where the holding member 48 is inserted into the insertion portion 410, the upper wall 40U of the cutter cradle 4A is positioned downward of the holding member 48 to face the same. The upper wall 40U includes a first sloped portion 44A, a first load portion 44B, and a first contact portion 44C.

Of the upper wall 40U, the first sloped portion 44A is a portion positioned frontward of the insertion portion 410, the first contact portion 44C constitutes a portion positioned rearward of the insertion portion 410, and the first load portion 44B is positioned rearward of the first sloped portion 44A and frontward of the first contact portion 44C. The first load portion 44B is aligned with and constitutes the insertion portion 410. That is, the first sloped portion 44A, the first load portion 44B, and the first contact portion 44C are arranged in this order in the rearward direction.

The first sloped portion 44A is sloped relative to the front-rear direction. As illustrated in FIG. 17 in detail, the first sloped portion 44A has a front end 441, and a rear end 442 adjacent to the first load portion 44B. The first sloped portion 44A is inclined diagonally frontward and downward as extending away from the rear end 442 to the front end 441. In other words, the first sloped portion 44A is inclined frontward such that the front end 441 is positioned further downward than the rear end 442.

The first sloped portion 44A and the holding member 48 are always spaced apart from each other in the up-down direction regardless of the relative position between the cutter cradle 4A and the holding member 48. With this configuration, a load is not imparted from the holding member 48 on the first sloped portion 44A even when the holding member 48 is moved.

The first load portion 44B protrudes upward so that the first load portion 44B is positioned further upward than the first sloped portion 44A. The first load portion 44B makes contact with a second load portion 45B (described later) of the holding member 48 in the state where the cutter cradle 4A is at the half-cutting position. The first load portion 44B directly receives a load from the holding member 48 to retain the cutter cradle 4A at the half-cutting position.

The first load portion 44B has a front end 443 adjacent to the first sloped portion 44A, and a rear end 444 adjacent to the first contact portion 44C. The first load portion 44B is inclined diagonally rearward and downward as extending away 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.

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

The holding member 48 includes a second sloped portion 45A, the second load portion 45B, and the second contact portion 45C, those are portions positioned upward of the cutter cradle 4A to face the same in the state where the holding member 48 is inserted into the insertion portion 410.

Of the holding member 48, the second sloped portion 45A is a portion positioned frontward of the insertion portion 410, the second contact portion 45C constitutes a portion positioned rearward of the insertion portion 410, and the second load portion 45B is positioned rearward of the second sloped portion 45A and frontward of the second contact portion 45C. The second load portion 45B is aligned with the insertion portion 410 in the up-down direction, and is positioned inside the insertion portion 410. That is, the second sloped portion 45A, the second load portion 45B, and the second contact portion 45C are arranged in this order in the rearward direction.

The second sloped portion 45A has a portion positioned upward of the first sloped portion 44A and face the first sloped portion 44A. The second sloped portion 45A is inclined relative to the front-rear direction. Specifically, the second sloped portion 45A has a front end 451, and a rear end 452 adjacent to the second load portion 45B. The second sloped portion 45A is inclined diagonally frontward and downward as extending from the rear end 452 to the front end 451. In other words, the second sloped portion 45A is sloped frontward such that the front end 451 is positioned further downward than the rear end 452.

The second sloped portion 45A and the first sloped portion 44A of the cutter cradle 4A are always spaced apart from each other in the up-down direction regardless of the relative position between the cutter cradle 4A and the holding member 48. Accordingly, the second sloped portion 45A does not apply a load to the cutter cradle 4A even when the holding member 48 is moved.

The second load portion 45B makes contact with the first load portion 44B of the cutter cradle 4A in the state where the cutter cradle 4A is at the half-cutting position. The second load portion 45B directly applies a load to the cutter cradle 4A to retain the cutter cradle 4A at the half-cutting position.

The second load portion 45B has a front end 453 adjacent to the second sloped portion 45A, and a rear end 454 adjacent to the second contact portion 45C. The second load portion 45B is inclined diagonally rearward and downward as extending 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.

The second contact portion 45C protrudes downward to be positioned further downward than the second load portion 45B, and makes contact with the first contact portion 44C of the cutter cradle 4A from above.

The cover 1D has an inner surface (i.e., a front surface) provided with a protruding portion 10F. The protruding portion 10F protrudes frontward toward the cutter cradle 4A attached to the support portion 26 in a state where the cover 1D closes the cassette receiving portion 2. The protruding portion 10F is configured to prevent unintentional detachment of the cutter cradle 4A from the support portion 26 of the cassette receiving portion 2. The protruding portion 10F has a protruding end (i.e., a front end) positioned away from the cutter cradle 4A in the front-rear direction to form a gap between the protruding portion 10F and the cutter cradle 4A.

[Printing Operation]

Next, a printing operation performed in the printing device 1 according to the first embodiment will be described. Ina state where the cover 1D opens the cassette receiving portion 2 (a state illustrated in FIG. 2), the platen holder 23 is at the remote position. Upon attachment of the cassette 9 to the cassette receiving portion 2 by the user, 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, a width direction of each of the transparent film tape 99A, the ink ribbon 99C, and the double-sided adhesive tape 99B is parallel to the front-rear direction.

Then, the platen holder 23 is pivotally moved from the remote position to the proximity position in accordance with a closing movement of the cover 1D. As a result, the platen roller 23B presses the ink ribbon 99C and the transparent film tape 99A those are superimposed against the printing head 21A. The conveying roller 23C presses the double-sided adhesive tape 99B and the transparent film tape 99A those are superimposed against the tape drive roller 91.

In response to input of print instructions by the user to the operating 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 is rotated together with rotation of the tape drive shaft 22A, and the conveying roller 23C is rotated following rotation of the tape drive roller 91. Hence, the double-sided adhesive tape 99B, the transparent film tape 99A, and the ink ribbon 99C are conveyed in the printing device 1.

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

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

The ink contained in the ink ribbon 99C is released from the ink ribbon 99C as the ink ribbon 99C is separated from the transparent film tape 99A at the separating position. The used ink ribbon 99C that has moved past the separating position is taken up by rotation of the ribbon take-up shaft 22B as the ribbon take-up roll 97D. The printed transparent film tape 99A that has moved past the separating position is directed to the second tape guide 95B by the rotation of the conveying roller 23C and the tape drive roller 91.

At a position between the tape drive roller 91 and the conveying roller 23C, one surface of the double-sided adhesive tape 99B and the transparent film tape 99A that has moved past the second tape guide 95B are bonded together to provide the cut target 99. The provided cut target 99 is conveyed toward the ejecting portion 93. The cut target 99 moved past the ejecting portion 93 passes through the cutting device 1E, and is discharged toward an upper portion of the housing 1A. Then, the drive motor and the printing head 21A are halted and the printing operation is terminated. A subsequent printing operation can be repeatedly performed in this way when the user inputs new print instructions through the operating portion 1B.

[Half-Cutting Operation]

How the half-cutting operation is performed in the cutting device 1E will next be described. The half-cutting operation is performed, for example, each time a printing operation is performed. In order to perform the half-cutting operation, the user operates only the cutter lever 5 to cause the cutter lever 5 to be moved in the direction indicated by the arrow C52 from the half-cutting standby position (see FIGS. 4 and 6) to the half-cutting operation position (see FIGS. 8 and 9) against the urging force of the cutter lever spring (not illustrated).

Through 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 be brought into contact with the cutter holder 32, thereby moving the cutter holder 32 against the urging force of the cutter spring (not illustrated). In accordance with the movement of the cutter holder 32, the cutter blade 30 is also moved leftward from the retracted position (see FIG. 4) to the cutting position (see FIG. 8).

Note that, when only the cutter lever 5 is operated by the user, the cutter cradle lever 6 is not moved and maintained at its full-cutting standby position. Accordingly, the cutter cradle 4A is maintained at the half-cutting position as illustrated in FIG. 14. In this state, the second part 422 of the cutter cradle 4A faces the cutter blade 30 at the position leftward of the cutter blade 30 as illustrated in FIGS. 8 and 14.

The cutter blade 30 moved together with the cutter holder 32 nips the cut target 99 in cooperation with the second part 422. The cutter blade 30 presses the cut target 99 leftward and is brought into contact with the pair of protruding parts 422B of the second part 422. Since the cutting edge of the cutter blade 30 cannot reach the flat surface part 422A of the second part 422, the cut target 99 is partially cut in a thickness direction thereof. As such, the half-cutting operation is performed with respect to the cut target 99 by the cooperation of the cutter blade 30 with the second part 422 of the cutter cradle 4A.

After completion of the half-cutting operation with respect to the cut target 99, the user releases operation to the cutter lever 5 to allow the cutter lever 5 to be moved back in the direction indicated by the arrow C51 (see FIG. 4) from the half-cutting operation position to the half-cutting standby position 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. Hence, the cutter holder 32 is moved by the urging force of the cutter spring to move the cutter blade 30 rightward from the cutting position (see FIG. 8) to the retracted position (see FIG. 4). The cutter blade 30 is thus accommodated in the box member 31.

[Full-Cutting Operation]

A process of the full-cutting operation will be described next. The full-cutting operation is performed, for example, after a printing operation and a half-cutting operation corresponding thereto are repeatedly performed. For performing the full-cutting operation, only the cutter cradle lever 6 is operated by the user to cause cutter cradle lever 6 to be moved in the direction indicated by the arrow C62 from the full-cutting standby position (see FIGS. 4 to 9) to the full-cutting operation position (see FIGS. 10 and 11) against the urging force of the cutter cradle lever spring (not illustrated).

In accordance with the movement of the cutter cradle lever 6, the pivot member 4B is also pivotally moved due to the urging force of the spring 49. A load is imparted on the cutter cradle 4A in response to the movement of the holding member 48, whereby the cutter cradle 4A is moved from the half-cutting position (see FIG. 13) to the full-cutting position (see FIG. 15). That is, the cutter cradle lever 6 makes contact with the cutter cradle 4A indirectly through the pivot member 4B for moving the cutter cradle 4A from the half-cutting position to the full-cutting position. At the full-cutting position of the cutter cradle 4A, the first part 421 of the cutter cradle 4A faces the cutter blade 30 of the cutter holder 32 at the position leftward of the cutter blade 30.

Further, in accordance with the movement of the cutter cradle lever 6, the contacting portion 62 of the cutter cradle lever 6 is brought 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 urging force of the cutter lever spring. That is, the cutter lever 5 is moved in interlocking relation to the cutter cradle lever 6 by the interlocking portion 10D due to the user operation only to the cutter cradle lever 6.

At this time, the protruding portion 52 of the cutter lever 5 enters the notched hole 31A of the box member 31 of the cutter portion 10B to move the cutter holder 32. Hence, the cutter holder 32 moves the cutter blade 30 leftward from the retracted position (see FIG. 4) to the cutting position (see FIG. 10).

The cutter blade 30 that has been moved together with the cutter holder 32 nips the cut target 99 in cooperation with the first part 421 of the cutter cradle 4A. The cutting edge of the cutter blade 30 presses the cut target 99 leftward, and is brought into contact with the first part 421. Since the cutting edge reaches the first part 421, the cut target 99 is completely cut in a thickness direction thereof and is divided into two parts. The full-cutting operation with respect to the cut target 99 is performed in this way by the cooperation of the cutter blade 30 with the first part 421 of the cutter cradle 4A.

The user operation to the cutter cradle lever 6 is released after termination of the full-cutting operation to the cut target 99. The cutter cradle lever 6 is moved back in the direction indicated by the arrow C61 (see FIG. 4) from the full-cutting operation position to the full-cutting standby position due to the urging force of the cutter cradle lever spring. Further, in accordance with the movement of the cutter cradle lever 6, the pivot member 4B is pivotally moved back against the urging force of the spring 49 to cause the cutter cradle 4A to be moved from the full-cutting position (see FIG. 15) to the half-cutting position (see FIG. 13).

Further, in accordance with the movement of the cutter cradle lever 6 to the full-cutting standby position, the contacting portion 62 of the cutter cradle lever 6 separates from the protruding portion 52 of the cutter lever 5. As a result, the cutter lever 5 is also moved back by the urging force of the cutter lever spring from the half-cutting operation position to the half-cutting standby position to cause the entry portion 52A of the cutter lever 5 to come out of the notched hole 31A of the box member 31 of the cutter portion 10B. Hence, the cutter holder 32 is moved rightward by the urging force of the cutter spring to move the cutter blade 30 rightward from the cutting position (see FIG. 10) to the retracted position (see FIG. 4). The cutter blade 30 is thus accommodated in the box member 31.

Advantageous Effects in Embodiment

In the printing device 1, when only the cutter lever 5 is operated by the user, the cutter blade 30 that has been moved together with the cutter holder 32 moved due to the movement of the cutter lever 5 and the cutter cradle 4A positioned at the half-cutting position perform the half-cutting operation with respect to the cut target 99 in cooperation with each other (see FIGS. 8 and 14).

On the other hand, when only the cutter cradle lever 6 is operated by the user, the cutter blade 30 that has been moved together with the cutter holder 32 moved due to the movement of the cutter lever 5 and the cutter cradle 4A that has been moved to the full-cutting position caused by the movement of the cutter cradle lever 6 perform the full-cutting operation with respect to the cut target 99 in cooperation with each other (see FIGS. 10 and 15). In this way, the full-cutting operation and the half-cutting operation with respect to the cut target 99 can be performed by the user operation to the cutter cradle lever 6 and the cutter lever 5.

As such, according to the printing device 1, the full-cutting operation and the half-cutting operation with respect to the cut target 99 can be selectively performed without providing a motor for moving the cutter blade 30 in the printing device 1. Therefore, a weight of the printing device 1 can be saved in comparison with a case where a motor is provided in a printing device.

In the printing device 1, the cutter lever 5 is positioned further frontward than the cutter cradle lever 6. Hence, the user firstly operates the cutter lever 5 positioned frontward of the cutter cradle lever 6 for performing the half-cutting operation with respect to the cut target 99, and then operates the cutter cradle lever 6 positioned rearward of the cutter lever 5 for performing the full-cutting operation with respect to the cut target 99. That is, the user can perform the half-cutting operation and thereafter the full-cutting operation in this order by operating the cutter lever 5 and the cutter cradle lever 6 in this order in the rearward direction. Accordingly, the user can intuitively distinguish the operation to the cutter lever 5 and the cutter cradle lever 6.

In the printing device 1, when the user operation only to the cutter lever 5 is performed, the cutter lever 5 and the cutter cradle lever 6 are not moved in interlocking relation to each other. On the other hand, the cutter lever 5 and the cutter cradle lever 6 are moved in interlocking relation to each other by virtue of the interlocking portion 10D when the user operation only to the cutter cradle lever 6 is performed.

Thus, the full-cutting operation with respect to the cut target 99 can be performed by the cooperation of the cutter cradle 4A that has been moved to the full-cutting position caused by the movement of the cutter cradle lever 6 and the cutter blade 30 that has been moved caused by the movement of the cutter lever 5 moved by the interlocking portion 10D. As a result, the full-cutting operation can be performed just by operating the cutter cradle lever 6, without the necessity of operating both the cutter lever 5 and the cutter cradle lever 6.

The both end portions in the front-rear direction of the cutter blade 30 is positioned further outward than the both ends in the front-rear direction of the cutter cradle 4A, respectively, both when the cutter cradle 4A is positioned at the half-cutting position (see FIG. 8) and when the cutter cradle 4A is positioned at the full-cutting position (see FIG. 10). Accordingly, the cut target 99 can be suitably cut by the cooperation of the cutter blade 30 with the cutter cradle 4A even in a case where the end portions in the lengthwise direction (the front-rear direction) of the cutting edge of the cutter blade 30 are distorted.

When the cutter cradle 4A is moved in the first moving direction Y11 from the half-cutting position to the full-cutting position, the support portion 26 is moved relative to the cutter cradle 4A in the second moving direction Y12, so that the right-lower corner portion of the support portion 26 is pressed against both the right wall 40R and the lower wall 40S of the cutter cradle 4A. With this configuration, when the cutting operation is performed with respect to the cut target 99 in the printing device 1, displacement of the cutter cradle 4A due to a force applied from the cutter blade 30 to the cutter cradle 4A can be restrained by virtue of the support portion 26. Accordingly, the printing device 1 can perform the cutting operation with respect to the cut target 99 appropriately.

The cutter cradle 4A is pivotally movable upon receipt of a pressing force from the holding member 48 at the contact portion 41. Since the contact portion 41 is positioned at the center in the front-rear direction of the cutter cradle 4A, distortion of the cutter cradle 4A in a direction in which the cutting edge of the cutter blade 30 extends due to the pivotal movement of the cutter cradle 4A upon application of the force from the holding member 48 to the cutter cradle 4A is unlikely to occur. Accordingly, the printing device 1 can perform the suitable cutting operation with respect to the cut target 99.

In the cutting device 1E, the first sloped portion 44A of the upper wall 40U of the cutter cradle 4A is inclined downward in the frontward direction as extending from the rear end 442 to the front end 441. Further, the second sloped portion 45A of the holding member 48 is inclined downward in the frontward direction as extending from the rear end 452 to the front end 451. With this configuration, the holding member 48 can be easily inserted into the insertion portion 410 of the cutter cradle 4A when the cutter cradle 4A is moved frontward during the attachment of the cutter cradle 4A to the support portion 26. Therefore, the process of the attachment of the cutter cradle 4A with respect to the support portion 26 can be facilitated.

The first load portion 44B of the upper wall 40U of the cutter cradle 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.

With this configuration, a force directed in the frontward direction is applied to the cutter cradle 4A in the state where the holding member 48 presses against the upper wall 40U of the cutter cradle 4A from above. The force is directed in a direction opposite a direction in which the insertion portion 410 of the cutter cradle 4A is detached from the holding member 48, i.e., the rearward direction. Accordingly, unintentional detachment of the holding member 48 from the insertion portion 410 can be suppressed by virtue of the first load portion 44B and the second load portion 45B.

In a case where the first sloped portion 44A of the cutter cradle 4A and the second sloped portion 45A of the holding member 48 contacts each other and a load is applied from the holding member 48 to the cutter cradle 4A, a force directed in the rearward direction for releasing the holding member 48 from the insertion portion 410 may be applied to the cutter cradle 4A, which leads to an unfavorable situation (i.e., unintentional detachment of the holding member 48 from the insertion portion 410).

However, according to the printing device 1, the first sloped portion 44A and the second sloped portion 45A are constantly spaced apart from each other in the up-down direction regardless of the positional relationship between the cutter cradle 4A and the holding member 48. Accordingly, unintentional detachment of the holding member 48 from the insertion portion 410 can be restrained.

The first load portion 44B of the cutter cradle 4A and the second load portion 45B of the holding member 48 are in contact with each other in the state where the cutter cradle 4A is positioned at the half-cutting position. In this state, when a load is imparted from the holding member 48 on the cutter cradle 4A, a force directed in the frontward direction (i.e., a direction in which the insertion portion 410 is attached to the holding member 48) is applied to the cutter cradle 4A from the holding member 48, thereby ensuring insertion of the holding member 48 into the insertion portion 410. Accordingly, by virtue of the first load portion 44B and the second load portion 45B, the insertion portion 410 can be retrained from being released from the holding member 48.

The cover 1D includes the protruding portion 10F for preventing detachment of the cutter cradle 4A from the support portion 26. Further, the gap is formed between the protruding portion 10F and the cutter cradle 4A when the cover 1D closes the cassette receiving portion 2. Hence, the cutter cradle 4A can be smoothly moved between the half-cutting position and the full-cutting position without a mechanical interference between the cutter cradle 4A and the protruding portion 10F.

[Modifications]

While the description has been made in detail with reference to the embodiment, it would 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 may be made thereto.

For example, the cutting device 1E may not be provided in the printing device 1, but may be provided in another device in which a cut target 99 is to be cut. Further, the cutting device 1E may not be provided in a device and may be an independent cutting device for cutting a cut target 99.

The display portion 1C and the cassette receiving portion 2 may be positioned at the same side of the housing 1A. That is, the display portion 1C and the cassette receiving portion 2 may be disposed close to each other in the front-rear direction. In this case, the cutter lever 5 may be positioned at a side where the display portion 1C and the cassette receiving portion 2 are positioned. The cutter lever 5 may be positioned further rearward than the cutter cradle lever 6.

In the printing device 1, the interlocking portion 10D (the combination of the protruding portion 52 and the contacting portion 62) may be dispensed with. In the latter case, the full-cutting operation with respect to the cut target 99 may be performed by a user operation to both the cutter lever 5 and the cutter cradle lever 6.

The length L30 in the front-rear direction of the cutter blade 30 may be equal to the length L40 in the front-rear direction of the cutter cradle 4A. In the latter case, the front end portion and the rear end portion in the front-rear direction of the cutter blade 30 may be aligned with the front end and the rear end in the front-rear direction of the cutter cradle 4A, respectively.

A direction in which the cutter cradle 4A is moved from the half-cutting position to the full-cutting position may be coincident with the upward direction. In this case, the support portion 26 may be pressed only against the lower wall 40S, and may not be pressed against the right wall 40R. Further, in this case, an urging force directed leftward may be applied to the cutter cradle 4A that has been moved from the half-cutting position to the full-cutting position. The support portion 26 may be pressed against the right wall 40R due to the leftward urging force.

The contact portion 41 may be provided over the entire length in the front-rear direction of the cutter cradle 4A. Alternatively, the contact portion 41 may be provided on each end portion in the front-rear direction of the cutter cradle 4A, and the contact portion 41 may not be provided at the center in the front-rear direction of the cutter cradle 4A. The contact portion 41 may have a configuration allowing the contact portion 41 to be engaged with the holding member 48. In the latter case, a state where the contact portion 41 is in contact with the holding member 48 may be maintained.

At least one of the first sloped portion 44A of the cutter cradle 4A and the second sloped portion 45A of the holding member 48 may extend in parallel to the front-rear direction. Particularly, the second sloped portion 45A of the holding member 48 may extend in parallel to the front-rear direction, while the first sloped portion 44A of the cutter cradle 4A is inclined downward in the frontward direction. Further, at least one of the first load portion 44B of the cutter cradle 4A and the second load portion 45B of the holding member 48 may extend in parallel to the front-rear direction.

Further, the first sloped portion 44A of the cutter cradle 4A and the second sloped portion 45A of the holding member 48 may be in contact with each other when the cutter cradle 4A is at the half-cutting position. Further, the first load portion 44B of the cutter cradle 4A and the second load portion 45B of the holding member 48 may be separated from each other when the cutter cradle 4A is at the half-cutting position.

The protruding end of the protruding portion 10F of the cover 1D may make contact with the cutter cradle 4A. Further, the cover 1D may not include the protruding portion 10F.

Although the combination of the transparent film tape 99A and the double-sided adhesive tape 99B is employed as an example of the cut target 99 in the above-described embodiments, other object may be the cut target 99. For example, printed paper, label, other kind of tape, tube and the like may be used as the cut target 99, and the cutting operation may be performed with respect to these objects by the cutting device 1E.
