There is. The paper 16 as a belt-shaped sheet shown in FIG. 1 is wound in a roll shape and is fed through the slot 12. An opening 18 extending in the longitudinal direction is formed in the center of the frame 10, and a stopper screw 20 is screwed in a rear end portion of the frame 10 so as to extend downward.

A support plate 21 is arranged below the frame 10 with a gap therebetween, and constitutes a main body of the apparatus together with the frame 10, and a movable cutter 24 of the frame 10 is provided between the frame 10 and the support plate 21. It is fitted so as to be movable in the longitudinal direction. The frame 10 has four guide protrusions 2
2 is provided so as to project downward, and the movable cutter 24 is guided for movement by these guide protrusions 22 and is positioned in a direction orthogonal to the movement direction. In addition,
An opening 25 larger than the opening 18 is formed in the support plate 21 at a position corresponding to the opening 18 of the frame 10.

The movable cutter 24 has a flat plate shape, and a cutting edge 26 is formed at the front end edge thereof as shown in FIG.
The cutting blade 26 has a V-shape that is closer to the rear end side of the movable cutter 24, and a cutout 28 is provided in the central portion of the cutting blade 26. Guide pieces 30 are provided on both ends of the cutting edge 26 in the longitudinal direction. These guide pieces 30
Has its upper surface inclined toward the lower side toward the tip, and the cutting blade 30 engages with the fixed blade 14 and the lower side of the fixed blade 14 prior to cutting the paper 16, and the cutting blade 26
To guide the movement of. Further, an elongated hole 32 extending in parallel with the moving direction of the movable cutter 24 is formed at the center thereof.

A drive piece 40 is attached to the movable cutter 24 so as to be relatively movable in the moving direction of the movable cutter 24. The drive piece 40 has a U-shape, and a slip film 44 is fixed to the outer surface of the U-shaped bottom wall 42. The drive piece 40 is disposed in the opening 25 of the support plate 21 and is brought into contact with the lower surface of the movable cutter 24 at the slip film 44, so that the screw 4 is inserted from the frame 10 side.
6 is an opening 18 of the frame 10 and an elongated hole 3 of the movable cutter 24.
It is attached to the movable cutter 24 by being screwed into the bottom wall 42 through the openings 2 of the support plate 21 and the support plate 21 and by being screwed with the lock nut 47 at the projecting end portion from the bottom wall 42.

The screw 46 is screwed between the movable cutter 24 and the slide plate 48 and the disc spring 50. The sliding plate 48 has a rectangular shape, is located in the opening 18 of the frame 10, and has a slip film 52 fixed to the lower surface thereof. The movable cutter 24 is sandwiched by the slip film 44 of the driving piece 40 and the slip film 52 of the driving piece 40.
Belleville springs 5 are provided between 4, 52 and the movable cutter 24, respectively.
0 produces a frictional force.

This frictional force adjusts the screwing amount of the screw 46,
It can be changed by adjusting the flexure amount of the disc spring 50. In the present embodiment, when the thickness of the sheet 16 is such that the movable cutter 24 cannot cut it, the movable cutter 24 can be cut.
It is adjusted to a size smaller than the backward load applied to the. Therefore, when the sheet 16 has a thickness that can be cut by the movable cutter 24 and the backward load applied to the movable cutter 24 when the movable cutter 24 is moved forward is smaller than the frictional force, the movable cutter 24 is used. Although the driving piece 40 and the sliding plate 48 move integrally, if the sheet 16 is thick and a load in the backward direction exceeding the frictional force is applied to the movable cutter 24, the driving piece 40 and the sliding plate 48 will move. As a result, a slip occurs, and only the driving piece 40 and the sliding plate 48 move forward. Slot 32, screw 46, nut
To 47, sliding plate 48, slip film 44, 52, etc.
The frictional coupling device is thus constructed.

A pair of U-shaped side walls 56, 5 of the drive piece 40
A cam 60 is fitted between the eight. The cam 60 is non-rotatably attached to a rotating shaft 64 that is rotated by an electric motor 62 (see FIG. 2). Cam 60
Is an eccentric cam having a cylindrical cam surface 66 that is eccentric to the axis of the rotating shaft 64. The farthest position of the cam surface 66 from the axis of the rotary shaft 64 is the long diameter portion 68, and the closest position is the short diameter portion 70. By rotating the cam 60, the drive piece 40 is linearly moved in a direction orthogonal to the rotation axis of the rotation shaft 64, and the movable cutter 24 is moved. The drive piece 40 constitutes a drive member, and
Together with the cam 60, a motion conversion mechanism that converts rotation into linear movement is configured. The motion converting mechanism constitutes a cutter driving device together with the electric motor 62 as a driving source.

The electric motor 62 is constantly rotating while the cash register is powered on.
It is a common drive source for each cash register device,
The rotation is transmitted to the rotary shaft 64 only when necessary, that is, only when the paper 16 is cut. This rotation transmission device is disclosed, for example, in Japanese Patent Application No.
It can be configured similarly to the sheet cutting apparatus described in the specification of No. 61728.

In the sheet cutting apparatus constructed as described above, usually, as shown in FIG. 1, the short diameter portion 70 of the cam 60 has the long diameter portion 68 on the inner side surface of the side wall 56 on the front side of the driving piece 40. The movable cutter 24 is in the original position where the rear end of the movable cutter 24 abuts on the stopper screw 20 in proximity to the inner surface of the rear side wall 58.

When it becomes necessary to cut the paper 16, the rotary shaft 64 is rotated, the cam 60 is rotated in the direction shown by the arrow in the drawing, the drive piece 40 is advanced, and the movable cutter 24 is moved. Can be moved forward. As shown in FIGS. 3 and 4, when the sheet 16 is thin and the movable cutter 24 has a thickness that can be cut, the backward load applied to the movable cutter 24 during forward movement is small, and the drive piece 4
0 and the frictional force between the sliding plate 48 and the movable cutter 24 is larger, the movable cutter 24 is advanced together with the driving piece 40 and the sliding plate 48, and advances to the cutting position to cut the paper 16. . In this case, since the notch 28 is provided at the center of the cutting blade 26, the center of the sheet 16 remains uncut even when the movable cutter 24 is moved to the cutting position. The operator tears off the leading end of the sheet 16 in this state.

After the movable cutter 24 moves to the cutting position,
When the cam 60 is further rotated, the drive piece 40 is retracted, and the movable cutter 24 is retracted together with the drive piece 40 to return to the original position.

Since the paper 16 is thick, the backward load applied to the movable cutter 24 is applied to the driving piece 40 and the sliding plate 4.
8 when the frictional force between the movable cutter 24 is exceeded,
A slip occurs between the driving piece 40 and the sliding plate 48 and the movable cutter 24, and as shown in FIGS. 5 and 6, the movable cutter 24 comes into contact with the sheet 16 and stops, while the driving piece 40 and the sliding plate 48. Moves forward with respect to the movable cutter 24. This relative movement is allowed when the screw 46 connecting the driving piece 40 and the sliding plate 48 moves in the elongated hole 32.

As described above, the paper 16 is thick and the movable cutter 2
Even when 4 does not cut, the cam 60 rotates further,
When the rotation phase for retracting the driving piece 40 is reached, the driving piece 40
And the sliding plate 48 and the movable cutter 24 are integrally retracted. At this time, the driving piece 40 and the sliding plate 48 are displaced from each other in the moving direction of the movable cutter 24, and the movable cutter 24 extends rearward from the driving piece 40 and the sliding plate 48 longer than when the sheet 16 is cut. ing. Therefore, the movable cutter 24 abuts on the stopper screw 20 screwed to the frame 10 before the cam 60 returns to the state of contacting the side wall 56 of the driving piece 40 at the short diameter portion 70,
After that, only the driving piece 40 and the sliding plate 48 move backward, so that the movable cutter 24, the driving piece 40, and the sliding plate 4 are moved.
The relative position with respect to 8 in the cutter movement direction returns to the same relative position as when the paper 16 is cut, and the next time the paper 16 is cut, the cutting can be performed as it is.

As described above, in the sheet cutting apparatus according to the present embodiment, when the sheet 16 is thick and cannot be cut by the movable cutter 24, the movable cutter 24 is allowed to stop, so that the movable cutter 24 is allowed to stop. An excessive load in the backward direction is not applied, and the movable cutter 24 and the cutter driving device are not damaged.

Further, the cutter driving device is operated in the same manner as when the movable cutter 24 can cut the sheet 16, and the transmission of the movement of the driving piece 40 to the movable cutter 24 is interrupted. Since the cutter driving device does not need to perform a specific operation in order to prevent the movable cutter 24 from performing the cutting operation, it is possible to inexpensively configure the sheet cutting device capable of avoiding damage to the movable cutter 24. .

Another embodiment of the present invention is shown in FIGS. In this embodiment, the movable cutter 8 is rotated by rotating the driving piece 80.
It is possible to move relative to 2. Like the movable cutter 24, the movable cutter 82 has a V-shaped cutting edge 83,
The sheet 90 (see FIG. 8) is cut together with the fixed cutter 88 that is the edge of the slit 86 formed in the frame 84.
The movable cutter 82 has a pair of slots 92 extending in a direction intersecting the longitudinal direction thereof and parallel to each other.
A pair of side walls 94 and 96 of the driving piece 80 having a U-shape are inserted into these slots 92 with a gap in the moving direction of the movable cutter 82.

The drive piece 80 is fitted in the opening 100 formed in the frame 84 and in the opening 25 of the support plate 21. A protrusion 104 is provided on the outer surface of the bottom wall 102 of the drive piece 80, and the drive piece 80 is biased via the protrusion 104 by a leaf spring 106 fixed to the upper surface of the frame 84 to move the bottom wall 102. It is pressed against the cutter 82.

When the sheet 90 has a thickness that allows the movable cutter 82 to be cut, the movable cutter 82 is moved by the drive piece 80.
However, when the sheet 90 has a thickness that cannot be cut by the movable cutter 82, the movable cutter 82 is moved forward.
A large backward load is applied to the drive piece 80, and the drive piece 80 rotates with respect to the movable cutter 82 as described later. Leaf spring 1
Ri Nodea the urging force of the 06 has been set as such, this
In the embodiment, the protrusion 104 and the leaf spring 106 are elastic.
It constitutes a sexual pressing device. The structure of the cutter driving device is the same as that of the above-mentioned embodiment, and the corresponding parts are designated by the same reference numerals and the description thereof is omitted.

In the present embodiment, when the sheet 90 has a thickness capable of cutting the movable cutter 82 as shown in FIG. 8, the sheet 90 is moved when the movable cutter 82 is advanced to cut the sheet 90. Since the backward load applied to the movable cutter 82 by the drive cutter 80 is not large enough to rotate the drive piece 80, the movable cutter 82 is advanced to the cutting position by the drive piece 80 as shown in FIGS. 8 and 9. Then, the paper 90 is cut.

On the other hand, when the sheet 90 is thick and the movable cutter 82 cannot be cut as shown in FIGS. 10 and 11, the sheet 9 is moved when the movable cutter 82 is advanced.
With 0, a load large enough to rotate the driving piece 80 is applied to the movable cutter 82. Therefore, the driving piece 80
Is rotated clockwise in the figure against the biasing force of the leaf spring 106 as the cam 60 rotates and the distance of the cam surface 66 contacting the front side wall 94 from the axis of the rotating shaft 64 increases. Do not move forward. Therefore, the movable cutter 82
Does not advance to the cutting position and is not overloaded and damaged.

When the rotation of the cam 60 causes the driving piece 80 to move backward, the driving piece 80 rotates counterclockwise, and the driving piece 80 is rotated as shown in FIG.
Then, the movable cutter 82 is returned to the original position by being retracted as the cam 60 rotates.

In the embodiment shown in FIGS. 7 to 11, the leaf spring 106 for pressing the drive piece 80 against the movable cutter 82 is used.
Although it is fixed to the frame 84, a spring may be provided between the drive piece 80 and the movable cutter 82. For example, with the side walls 94 and 96 of the driving piece 80 fitted in the slots 92 from the frame 84 side, the movable cutter 82 is provided on the bottom wall 102 and the movable cutter 24 of the driving piece 80 from below the movable cutter 24. Through the through hole, the screw drive piece 80 is screwed and connected to the bottom wall 102 of the screw drive piece 80, and a disc spring is sandwiched between the head of the screw and the movable cutter 24 to attach the bottom wall 102 of the drive piece 80 to the movable cutter 82. Try to attract them.
