[0002]
[Prior art]
Conventionally, a print medium such as a continuous belt-like label or a tag (tag) is transported along a predetermined transport path, and a product price, product number, and other printing information is printed by a printing mechanism, and then a predetermined pitch. There is a printing device that cuts this. There is also a case where a label continuous body or tag printed in advance is used as a cutting device for cutting at a predetermined pitch as a medium to be cut.
Such a label continuum or tag displays predetermined product information by sticking it to a product or hanging it.
[0003]
The cutting device has various structures, but is generally provided as a cutter unit on the downstream side of the printing mechanism.
Such a cutting device, particularly when cutting a continuous label having an adhesive layer on its back surface, causes adhesive and fine chips to adhere to the cutter side of the cutting device little by little during cutting. It needs to be cleaned regularly. Even in the case of a tag or the like that does not have an adhesive layer, fine chips adhere to it, and it is necessary to clean it.
[0004]
Therefore, it is desirable that the cutting device provided so as to intersect the transfer path be moved away from the transfer path for cleaning work, but the cutting device is cleaned with a simple configuration. A structure that can do this is required.

The drawer support shaft 29 is fixed to the apparatus frame 2 in a cantilevered manner in a direction perpendicular to the apparatus frame 2 (so as to cross the transfer path 4), a pair of upper and lower sides, and slightly shifted upstream and downstream. is there.
In particular, as shown in FIG. 7, the drawer support shaft 29 is tapered in the drawer direction at the center.
[0030]
The unit frame 13 has a pair of upper and lower large-diameter holes 32 (FIG. 7) and small-diameter holes 33 (FIG. 6) facing each other in the horizontal direction so that the drawer support shaft 29 can be inserted across the left and right sides. The unit frame 13, that is, the entire cutter unit 6, is formed along the drawer support shaft 29, at the first position (storage position, cutting position, solid line in FIG. 7) and second position (drawing position, cleaning position, FIG. Middle imaginary line).
[0031]
The bearing mechanism 30 enables the cutter unit 6 or the unit frame 13 to move along the drawer support shaft 29, and is provided inside the bearing housing 34 and a bearing housing 34 provided facing the large-diameter hole 32. A bearing collar 35 and a pair of left and right slot rings 36 of the bearing collar 35.
[0032]
The bearing collar 35 prevents the bearing mechanism 30 from moving against the drawer support shaft 29 when the unit frame 13 is moved along the drawer support shaft 29.
[0033]
The slot ring 36 can be slidably brought into contact with the drawer support shaft 29, so that the difference in resistance when the unit frame 13 is moved in the drawer direction and the storage direction can be sensed for convenience of operation. To.
[0034]
Further, the drawer support shaft 29 and the bearing mechanism 30 can be used in any direction (horizontal direction, vertical direction, or any other direction) depending on the orientation of the thermal printer 1 with a sticking mechanism or the cutter unit 6. A predetermined frictional force is applied between the unit frame 13 and the danger of the unit frame 13 moving naturally.
[0035]
The lock mechanism 31 enables the unit frame 13 to be fixed at the first position, and is a lock plate that can be engaged with and disengaged from a lock groove 37 (FIGS. 2 and 3) formed in the distal end portion 29A of the drawer support shaft 29. 38 (FIG. 2).
[0036]
The lock plate 38 is rotatable around a rotation shaft 39 attached to the drawer side (front side) side surface of the unit frame 13, and communicates with the small diameter window 40 that engages with the lock groove 37. A large-diameter window 41 is formed, and a knob portion 42 (FIG. 3) is formed in a perpendicular direction.
[0037]
If necessary, a stopper ring 43 (imaginary line in FIG. 7) is provided in the middle of the drawer support shaft 29, so that the bearing mechanism 30 or its bearing housing 34 can be brought into contact with the stopper ring 43, and the unit frame.

In the pulled-out state, the side cover (not shown) of the thermal printer 1 with the pasting mechanism is opened, and the non-mounting label L loaded from the supply shaft 3 of the non-mounting label L via the printing mechanism 5 is transferred to the cutter mechanism 14. When loading between the fixed blade 15 and the rotary blade 16 and between the drawing roller 18 and the pressing roller 19 of the label drawing mechanism 8, the operation can be facilitated.
[0043]
When returning from the second position to the first position, the unit frame 13 may be pushed in the direction of the apparatus frame 2 as it is, and the operability is good.
During this pushing operation, the slit ring 36 is in sliding contact with the thick portion of the taper on the base side of the drawer support shaft 29, so that the certainty of the operation can be realized from the difference in resistance.
[0044]
After the pushing operation is completed, if the small-diameter window 40 is engaged with the lock groove 37 of the pull-out support shaft 29 by rotating the knob portion 42 of the lock plate 38 in the lock mechanism 31 around the rotation shaft 39, the pull-out support is achieved. The shaft 29 and the cutter unit 6 can be securely fixed at the first position.
