DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stamp device that is installed in, for example, a label printer and prints product names and the like.

FIG. 1 is a diagram showing a schematic configuration of a label printer,
Inside the main body case 1, a detector 2, a printer 3, a stamp device 4, a feed roller 5, a take-up shaft 6, etc. are arranged, and above the case 1 there is a length of label paper 7 pasted with a predetermined length. The shaku mount 8 is set on the supply shaft 9 in a rolled state.

Then, the long mount 8 pulled out from one end of the roll is sequentially guided to the printer 3 and the stamp device 4 via the label presser 10 which also serves as a guide and the detector 2, and is further guided to the printer 3 and the stamp device 4 by the feed roller 5 and the tension roller 11. It is wound up on the winding shaft 6 through the gap.

In the printer 3, numbers such as weight, unit price, price, etc. are printed on the label paper 7, and in the stamp device 4, characters such as the product name are stamped, for example, beef (for loin sukiyaki).

Thereafter, the stamp receiver of the long mount 8 is bent at an acute angle at the edge of the table 12, and is passed through the tension roller 11 and directed toward the take-up shaft 6, so that when it is bent at the edge of the table 12, , the label paper 7 is peeled off from the mount 8, the label paper 7 with predetermined information printed on it is discharged from the outlet 13 of the main case 1, and is placed on the predetermined product or the wrapping paper that wrapped the product outside of the main case 1. be pasted on.

Stamp devices that can be used for the above purposes include:
It is necessary to be able to replace stamps with various product names as appropriate.

Therefore, generally, as shown in FIG. 2, a stamp holder 15 that holds the stamp 14 is formed of a magnetic material, and a magnet 17 is fixed inside the stamp base 16, so that the stamp holder 15 is magnetically attached to the stamp base 16. I try to attach it by adsorbing it.

However, according to the conventional device shown in FIG. 2, the attraction surface 17a of the magnet 17 is slightly recessed from the peripheral edge 16a of the stamp holder 16, and the upper part of the stamp holder 15 is fitted inside the peripheral edge 16a. Therefore, to attach the stamp holder 15 to the stamp pad 16, position the holder 15 directly below the stamp pad 16 as shown by the imaginary line in FIG. need to be moved to.

However, there are cases where the holder 15 is attracted to the stamp pad 16 before it is positioned just below it, as shown in FIG.
7, it is extremely difficult to correct the stamp to an appropriate position, which makes it difficult to attach the stamp.

The present invention was devised to eliminate these drawbacks of conventional devices, and its purpose is to provide a very simple improvement to a stamp device in which a stamp holder that holds a stamp is attached to a stamp base by magnetic attraction. The purpose of this addition is to facilitate the installation of the stamp.

Hereinafter, the structure of the present invention will be explained based on the embodiments shown in FIGS. 4 to 7.

Figure 4 shows two stamp holders 21a and 21b.
This figure shows the state in which the stamp pad 22 has been removed from the stamp pad 22, and a support shaft 23 is provided protruding from the upper surface of the stamp pad 22.

Further, the stamp pad 22 is provided with two recesses 24 (only one shown in FIG. 5) that open downward, and each recess 2
A magnet 25 is fixed inside 4 as shown in FIG.

Furthermore, as representatively shown in FIGS. 4 and 6, a guide wall portion 22b is integrally formed on both left and right side walls 22a of the recess 24, and a guide wall portion 22b is formed in the inner part of this wall portion 22b. A positioning recess 26 is formed along a direction perpendicular to the insertion direction of the stamp holders 21a and 21b.

This positioning recess 26 has a semicircular shape.

On the other hand, each of the positioning recesses 26 is provided on the inner upper surface of both side walls of each of the stamp holders 21 a and 21 b.
Positioning convex portions 27 a , 27 a and 27 that fit into the
b and 27b are integrally provided.

All of these convex portions are formed in a semicircular shape.

Each of the stamp holders 21 a and 21 b opens upward and also has an opening on the lower surface side through which the character surface 28 a of the stamp 28 projects.

After the stamp 28 is housed in each holder 21a, 21b from above, the upper surface side of the holder 21a, 21b is covered with a cover 291, 29b made of a magnetic plate.

Note that each stamp holder 21a, 21b has a handle 30.
a, 30b is the installation.

Then, hold the handles 30a and 30b and touch the positioning protrusions 27a and 2 of each stamp holder 21a and 21b.
7a, 27b, and 27b are brought into contact with both side walls 22a of the stamp pad 22 as shown by imaginary lines in FIG. When the stamp holders 21 a and 21 b are inserted horizontally to the back side as shown by the arrow 13 using the stamp holders 21 a and 21 b as a guide, the positioning protrusions 27 a and 27 b are opposed to the positioning recesses 26 of the stamp pad 22, and the cover is inserted at that position. 291.29b is attracted to the magnet 25 in the stamp pad 22, and the concave and convex portions are fitted together.

As shown in FIG. 7, the support shaft 23 is engaged with a rotating end of a lever 31 provided inside the main body case of the label printer.

The lever 31 is rotatable about a shaft 32 and is biased counterclockwise in the drawing by a spring 33.
It is connected to the movable iron core No. 5.

Therefore, when the coil of the plunger 35 is energized, the lever 31 rotates clockwise, and the stamp holder 22 descends, and the stamp 28 held in each stamp holder 21 a, 21 b is placed on the label paper on the table 36. 37
It comes into pressure contact with the

According to the stamp device configured as above, when attaching the stamp holders 21a, 21b to the stamp stand 22, the positioning convex portions 27a, 27b, and 2 of each holder are attached.
7 b and 27 b are the positioning recesses 2 of the stamp pad 22
Since the cover 29 of each holder will not be attracted to the magnet 25 in the stamp pad 22 unless it is fitted into the third
The situation shown in the diagram does not occur.

In other words, the stamp holders 21 a and 21 b are attracted to the magnet 25 only at proper positions, and these holders 21 a.

As long as the positioning convex parts 27 a and 27 b are fitted into the positioning recess 26 , the positioning part 21 b will always be located at the proper position.

Therefore, according to this stamp device, the positioning recess 26 is provided in the stamp stand 22, and the stamp holder 21 a
