In this way, the rotating piece 35, the protrusion 34 and the pressing piece 25
As shown in FIG. 9, the stopper mechanism consists of a locking pawl 37, an engaging groove 38, and a pressing piece 2.
5 may be used, and in this case, the locking pawl 37 may be always urged in the direction of separation from the engagement groove 38 by the spring 39.

A printing device 9 other than the printing device 4 can be detachably attached to the mounting frame 5.

This device 9 has a mounting frame 5 as shown in FIG.
A base body 91 made to be screwed onto the mounting portion 53 of the
A printing plate 9 is removably attached to the base 91.
2, and a leaf spring 93, which is an elastic body provided on the printing plate 92, and the printing plate 92 is attached to the base 91 so that the plate surface is located downward, and the plate spring 93 is attached to the base 91 so that the plate surface is located downward. 92 is configured to absorb the pressing force applied in the vertical direction.

For this purpose, in the embodiment, an insertion groove 911 is provided in the base body 91, and a locking portion 921 of the printing plate 92 is inserted into the insertion groove 911.
At the same time, a locking portion 92 is inserted into the insertion groove 911.
A plate spring 93 is interposed in a state in which 1 is pressed down.

Furthermore, in the labeler of the present invention, as shown in FIGS. 1 and 2, a label presser 15 is attached to the label presser 12, whereby both sides of the label are pressed against the receiving surface 82.

Therefore, even if the label 72 is curled due to the winding pattern, it can be spread out tightly on the receiving surface 82, and
Peeling can advance straight toward the presser 12. Furthermore, in the labeler of the present invention, as shown in FIG. At the time of return, the attachment frame 5 is engaged and pulled up by the hook 26, so there is an advantage that the attachment frame 5 can be reliably returned.

Furthermore, the drum 32 of the transfer device 3 is provided with a gear (not shown) that is concentric with the drum, and the pressure rollers 33 and 33' are also provided with gears that mesh with the gear of the drum 32, respectively. It is provided. Therefore, the drum 32 and the pressure rollers 33,3
3' are interlocked, so if the transfer tape 71 is inserted between the pressure roller 33 and the drum 32 and the lever 2 is moved back and forth, the drum 32 will rotate and the transfer tape 71 will automatically guard the drum 32. It can be set by feeding it between 36 and 36 seconds.

Since the labeler of the present invention is as described above, when the lever 2 is rotated upward in the direction of the arrow from the stationary state shown in FIG. The pressing piece 25 presses the rotating piece 35 while the piece 61 is driven.
The rotating piece 35 separates from the rotating piece 35 and becomes free, and at the same time, the rotating piece 61 is rotated from the state shown in FIG. 6B to the state shown in FIG. 7B.

This operation of the rotary piece 61 is performed only at the beginning of the operation of the lever 2, and at this point, the ink roller 63 moves while rubbing against the print line 4' of the printing device 4 to print. Evacuate from row 4'.

When the lever 2 further rotates upward in the direction of the arrow, the pressing piece 24 of the lever 2 comes into contact with the bearing shaft 54 of the mounting frame 5 and applies a pressing force thereto, so that the mounting frame 5 rotates downward as shown in FIG. 8A. The print line 4' of the printing device 4 is pressed against the label 72' on the receiving surface 82. During this lowering operation of the mounting frame 5, as shown in FIG. 8B, the drive shaft 22 descends without driving the rotating piece 61, so the ink roller 63 is stopped at the retracted position.

Next, when the lever 2 is rotated downward in the direction of the arrow shown in FIG.
Then, the drive shaft 22 reaches the upper end of the guide hole 64 and rotates the rotating piece 61 to return, so the ink roller 63 returns to its original position while sliding against the print row 4' again. .

At this time, the rack gear 23 of the lever 2 drives the one-way clutch 31, so the drum 32 rotates a predetermined angle clockwise in the figure to transport the transport tape 71 by the length of the label.

This rotation of the drum 32 is made possible by the protrusion 34' pushing up the guide edge 352 of the rotating piece 35 and releasing the protrusion 34 from the hook 351 of the stopper 35.

Next, when the lever 2 returns completely, the pressing piece 2
5 presses the rotating piece 35 and locks the protrusion 34, so that the drum 32 is fixed unrotatably from then on.

Although the above-mentioned embodiment has been described with respect to a so-called scraped type labeler, the present invention is not limited thereto, and can be implemented on a labeler equipped with a printing device. It can also be carried out using a labeler such as that described in Publication No. 19599 of 1972.

As described above, in the labeler of the present invention, since the ink roller 63 is driven independently from the printing device 4, the moving distance of the ink roller 63 can be set as desired, and as a result, the ink roller 63 can be driven independently. Since the printing device 4 can be moved in the printing arrangement direction to apply ink to the printing row 4',
By providing a plurality of printing devices 4, 4, etc., ink can be applied to these printing devices at the same time, and the drum 32 is fixed by a stopper mechanism so that it cannot rotate except during feeding operation. Therefore, the feeding dimension of the transfer tape 71 is accurately regulated, which has the effect of effectively preventing the occurrence of printing misalignment.
