SUMMARY OF THE INVENTION According to the present invention, there is provided a slider which detachably accommodates a cutter holder for accommodating a cutter, and which is slidably provided on a machine base, and which is opposed to a sliding direction of the slider. In a cutting device of a tube or label tape printer including a cutter holder that comes into contact with a cutter of a cutter holder housed in a slider, the cutter is movably movable so that its blade edge projects outside the cutter holder and fits in the cutter holder, and The cutter holder is provided with cutter support means for supporting and accommodating the cutting edge of the cutter in the cutter holder in a state of being removed from the slider, and the cutter projecting moving means for moving the cutter when the slider is mounted on the cutter holder and projecting the cutting edge out of the cutter holder is provided on the slider. It is characterized by having, furthermore,
The cutter supporting means comprises a cutter supporting arm having elasticity for supporting the cutter in a state in which the cutting edge of the cutter is accommodated in the cutter holder, and the cutter projecting and moving means engages with the rear surface of the cutter in the cutter holder in a state where the cutter holder is mounted. It is preferable to include a cutter back engaging member that protrudes the blade edge of the cutter out of the cutter holder against the elasticity of the support arm. Furthermore, the cutter holder is detachable from the machine base.
The cutter holder is provided on the cutter holder.
An elastic member may be provided between the back side of the
preferable.

[0005]

When the cutter holder containing the cutter is inserted into the slider, the cutting edge of the cutter protrudes from the cutter holder.
If the slider is slid in this direction in the cutter receiving direction,
Tube or label tape cut by cutter and cutter holder
Is done. Also take out the cutter holder from the slider
Then, the cutting edge of the cutter is accommodated in the cutter holder.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cutter, and the cutter 1 has a groove on the back surface 1b of the cutting edge 1a.
Formed 1 c and the chamfered 1d is, hole 1e is provided in a central portion. However, there is no problem even if the groove 1c is not formed. Reference numeral 2 denotes a cutter holder. The cutter holder 2 is provided with a cutter support arm 2a having elasticity. The cutter support arm 2a further includes a projection 2b pivotally connected to the hole 1e.
And a knob 2c and a guide portion 2d are formed. FIG. 1 is a view in which a cutter 1 is supported by a cutter holder 2, and the hole 1e of the cutter 1 has a cutter supporting arm.
Of the cutter supporting arm 2a.
Through elasticity, it is movable in the left-right direction in the figure and
Before mounting on a slider, as shown in the figure,
1a is housed in cutter holder 2 so as not to protrude
Have been. The cutter 1 may be provided with a plurality of holes 1d, and the cutter support arm 2a may be provided with a plurality of protrusions 2b at positions matching the holes 1d.

Reference numeral 3 denotes a slider.
A substantially rectangular notch 3a having an open upper surface and a left side surface in the figure is formed. A guide 3b pivotally connected to the guide portion 2d of the cutter holder 2 is provided in the notch 3a in a vertical direction . A circular hole 3c penetrating in the left-right direction is formed, and a hole 3e connected to the V-shaped groove 3d is provided at one end of the right side surface in the figure.
The rear receiving shaft 4 of the cutter is press-fitted. Since the slider 3 is configured such that, when inserting the cutter holder 2 in the rectangular notch 3a along the guide portion 2d cutter holder 2 in the guide 3b, the cutter 1 is the back 1b painter
By engaging with the rear receiving shaft 4 of the cutter, the cutter support arm
The cutter 2 moves against the elasticity of the
1a is projected. Further, if a groove 1c is formed in the cutter 1, when the groove 1c is engaged with the back receiving shaft 4 of the cutter, the cutter 1 is clicked on by the elasticity of the cutter support arm 2a, and the cutter 1 and the cutter holder 2 It can be seen that is positioned normally with respect to the slider 3.
Reference numeral 5 denotes a roller, and the roller 5 is provided in a hole 3e connected to the V groove 3d.

Reference numeral 6 denotes a slider holder, and this slider
The holder 6 is fixed to the base plate 10 with screws 11,
A shaft 7 which penetrates through the hole 3c of the slider 3 is provided below the shaft 7.
In addition to this, a spring 8 is inserted into the shaft 7 to urge the slider 3 rightward in the drawing.
I have. An elastic body 9 is provided in the upper groove of the slider holder 6.
Is installed. Reference numeral 12 denotes a cutter receiving holder. The cutter receiving holder 12 is formed of a flexible material.
2a, the hook portion 12b, knob 12c is formed, in addition to metallic cutter receiving 12d are provided, so as to project a pair of stoppers 12e is is configured to telescopically to the slider holder 6, the cutter receiving Hold the holder 12 with the slider
When it is attached to the rudder 6, an elastic body
9 is located.

Reference numeral 13 denotes a cam. The cam 13 has a cam portion 13a and a cam gear 13b integrally formed. The cam portion 13a is engaged with the roller 5, and is rotatable on the base plate 10 by a shaft 14. Is provided. Reference numeral 15 denotes a stepping motor. The stepping motor 15 is fixed to the base plate 10, and a motor gear 16 is fixed to a shaft 15a.

[0010] Since the thus configured, as shown in FIGS. 8 to 9, the cutter holder 2 while the exfoliation paper labeled tape 17 provided with the cutter receiving holder 12 and the cutter 1 provided with the cutter receiving 12d , The slider 3 moves in the cutter receiving direction via the motor gear 16, the cam gear 13 b, the cam portion 13 a, the roller 5 and the like by the rotation of the motor 15, and is mounted on the cutter 1 mounted on the slider 3 and the slider holder 6. The label tape 17 is cut by the cutter receiver 12d. However, cutting the only label tape in this figure, peeling Hanareshi is not cut, but shows a state in which the blade is衝止the stopper 12e, remove the stopper 12e, or if caused to avoid the label tape At the same time, the whole release paper can be cut.

Further, as shown in FIG. 10, even when the tube 18 is located between the cutter receiver 12d and the cutter 1, the cutter 18 similarly mounted on the slider 3 and the cutter receiver 12d mounted on the slider holder 6 provide the same. The label tape 17 is cut or half-cut.

[0012]

According to the present invention, the cutter holder can be slid.
After removing the cutter from the holder, the cutter edge is set in the cutter holder.
So that your fingertips do not touch the cutting edge of the cutter
It is safe and can protect the cutting edge. More cutter
The rudder itself has no deformation such as expansion and contraction.
Make sure that the cutting edge does not appear when touching the cut holder
Has become. Also, attach the cutter holder to the slider
Then, the blade edge of the cutter protrudes from the cutter holder,
Cutting and half-cutting of tubes and tapes is no problem
I can do it. In addition, since an elastic body is provided on the back of the cutter receiver,
This elastic body expands even when excessive force is applied to the cutting edge.
Shrinkage can reduce cutter wear.
Cut only the label tape of the label tape with release paper
Half cut and tube half cut smell
The cutter holder is averaged from the cutter by the expansion and contraction of this elastic body.
To maintain the parallelism between the cutter and the cutter holder.
And the accuracy of the half-cut device can be complemented.
The cut is made accurately.
