BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing type stamp having an ink pad on an upper part of a stamp body and inverting a printed body by 180 degrees for printing.

2. Description of the Related Art Conventionally, this type of reversal stamp is disclosed in U.S. Pat. Nos. 4,432,281, 4,841,860, and 49709.
No. 64, JP-A-1-218881 and the like.
In this type of stamp, the stamp body is always brought into contact with the ink pad by a coil spring, and at the time of stamping, the stamp body is turned approximately 180 degrees and stamped. The coil spring is a highly elastic spring for keeping the stamp body and the ink pad in contact with each other. Now, these reversing stamps are assembled by holding a control plate for reversing the stamp on the inner frame and fixing the reversing shaft to the outer frame. These have the drawback that a control plate is required, the number of parts increases, the cost increases, and the printed body must be reduced in size by the thickness of the control plate. Thus, US Pat.
No. 2,950,676, in order to eliminate these drawbacks, a rotary stamp in which a shaft is movably held by providing an elongated hole in the outer frame body in a direction perpendicular to the marking direction without using a control plate. Has been proposed. However, it is necessary to attach a washer or the like so that the shaft does not fall out of the long hole of the outer frame.
Since the washer is always in contact with the side surface of the long hole and moves while contacting the side surface of the long hole together with the shaft during printing, an excessive load must be applied at the time of printing. Therefore, the force of the coil spring must be increased. Further, when the coil spring is strengthened, the stamped surface may strongly collide with the ink cartridge after stamping, and the ink may scatter from the ink occluding body. For this reason, the coil spring should have the smallest possible force. Further, there is a disadvantage that the shaft must be disassembled and disassembled when it is desired to replace the stamp surface after assembling as a stamp. In addition, contact noise between the washer and the side surface of the long hole was generated.

[0002]

The problem to be solved by the present invention is that the force of the coil spring in the prior art is large,
It is an object of the present invention to provide a reversible stamp which is inexpensive and can reduce the sound during use by eliminating the disadvantages of being difficult to assemble and the disadvantage that the size of the stamp is larger than the stamp surface.

[0003]

The present invention solves the above-mentioned problem by making the stamp body 16 and the reversing shaft 14 detachable.

[0004]

The projection 1 is located near the base of the vertical plate 17 of the stamp body 16.
9, the reversible shaft 14 provided with the deformed portion 15 at the center was made detachable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS.
This will be specifically described with reference to FIG. Reference numeral 1 denotes an inner frame, which is box-shaped, and the long-side leg 3 is partially open. A control slit 4 is provided substantially vertically in the center of the short side leg 2 of the inner frame 1 and a guide projection 5 is provided inside the control slit 4. A window 6 larger than the print body is provided at the lower end face, and an ink cartridge 7 is held above the print body. Reference numeral 10 denotes an outer frame, which is box-shaped and has a long hole 13 on a short side surface 12 and a guide groove 11 at both inner end portions. The outer frame 10 and the inner frame 1 can be slidable in the guide groove 11. Reference numeral 21 denotes a coil spring that constantly pushes the outer frame body 10 upward. 14,
In the figure, a deformed portion 15 is provided substantially at the center of the reversal axis. The deformed portion 15 is slightly smaller than the diameter of the reversing shaft. Further, as another shape, a plate shape or a large diameter may be used, that is, the central portion may have a different cross-sectional shape from both end portions of the reversing shaft. The deformed portion prevents the reversing shaft 14 from coming off. Reference numeral 16 denotes a stamp body, and a printed body 20
Holding. Two vertical plates 17 are erected in parallel at intervals larger than the diameter of the reversing shaft 14 and are divided into three by slits 18. A protruding portion 19 is provided near the inner lower end of the vertical plate 17 so that the reversing shaft 14 and the stamp main body 16 can be detached. The guide projection 5 of the inner frame 1 moves up and down in the gap between the two vertical plates 17. The printing body 20 has a thickness of 0.5 only on the printing body surface.
It is a porous body of about mm or a non-porous body. The ink occluding body 8 of the ink cartridge 7 has felt, sponge, etc. impregnated with ink.
A knob 9 is provided to prevent a finger from being stained with ink when the ink cartridge 7 is replaced.

[0006] An assembling method using the above components as stamps will be described. A coil spring 21 is placed on the upper portion of the inner frame 1 and is covered with the guide groove 11 of the outer frame 10, and the reversing shaft 14 is inserted into the long hole 13 of the outer frame 10 and the control slit 4 of the inner frame 1. 1 and the outer frame 10 are combined. The reversing shaft 14 is temporarily held in the long hole 13 and the control slit 4 by the coil spring 21. Next, the stamp main body 16 is turned downward with the printed body, and the guide projection 5 is inserted into the gap of the vertical plate 17 so that the inner frame body 1 is inserted.
In the window 6. The reverse frame 14 is pushed downward against the coil spring 21 so that the reversing shaft 14 passes through the vertical plate 17 and
When the outer frame body 10 is further pressed by aligning the position 5, the outer frame body 10 is pushed over the protrusion 19, and the stamp main body 16 and the reversing shaft 14 are fitted and held to form a stamp. Next, the ink cartridge 7 is inserted into the inner frame 1 to complete the assembly. The coil spring 21
If the repulsive force is too small, the adhesion of the ink is insufficient and clear marking cannot be performed. Therefore, the strength of the spring is determined based on the contact pressing force per unit area of the printing body 20.

[0007]

[Effect] As described above, the present invention is directed to the vertical plate 1 of the stamp body 16.
7, a projection 19 is provided in the vicinity of the base, and the central portion of the reversing shaft 14 is formed into a deformed portion 15, and the projection 19 of the stamp body 16 is fitted and held on the reversing shaft 14. Body 1
Since the contact area with the long slot 13 was minimized, the force of the coil spring could be reduced and the marking load could be reduced. Further, the assembling was simple because no washer or the like was required, and could be manufactured at low cost, and the noise generated during use could be reduced.
