Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversal type rotary stamp having an ink pad on the upper side of a rotary stamp which is a combination of a rotary stamp and a fixed stamp, and which prints by reversing the rotary stamp by 180 degrees.

2. Description of the Related Art Conventionally, this type of reversal type rotary stamp has been well known in US Pat. Nos. 1,730,365 and 20,790,080, German Patent No. 379552, and Japanese Patent Laid-Open No. 61-89080. This type of rotary stamp is a stamp in which a rotary stamp and a fixed stamp are integrated, and the printing surface and the ink pad are always brought into contact with each other by a coil spring, and when the stamp is stamped, the rotary stamp is reversed by approximately 180 degrees and is stamped. .
However, the rotation mark and the fixed stamp are securely fixed without rattling, and the printing surface of the rotary stamp and the printing surface of the fixed stamp must be on the same plane for clear imprinting. Configuration is required. That is, the fixed and fine adjustments are indispensable, but these two are in conflict with each other, and therefore have a complicated configuration.

In US Pat. No. 1,730,365, since the fine adjustment is performed with the screw 40, the structure of the fixed stamp portion is complicated, the cost is increased, and a clearance is required between individual parts. There is noise when using it. Further, No. 2079080 has a structure in which it is fixed with a rivet 59 and finely adjusted with a knob 88, but the number of parts is also increased and the structure is complicated. German Patent No. 379552 and Japanese Patent Laid-Open No. 61-8
It is the same as 9080. In this application, since the hole 17 of the fixed stamp portion has to be formed, the mold structure becomes complicated, and further, the rattling of the rotation stamp portion and the fixed stamp portion is fixed by the hole 17 of the fixed stamp portion and the shaft 9. Furthermore, it must be fixed with screws 16. The reason why these known constructions have to be strong is that the reversing type rotary stamp is rotated 180 degrees about the reversing axis, so that the rotation speed is faster than it appears. Furthermore,
Since the pressure is applied against the coil spring, the marking pressure at the time of marking is also high. In order to satisfy these conditions,
It is well known in the art to make fine adjustments with screws, and it is easy and reliable to reduce the pitch of the screws.
However, it has been desired that the rotary mark portion and the fixed stamp portion be securely held, there is no rattling at the time of marking, there is little noise, light weight, easy at the time of assembly, and clear marking is possible.

[0003]

SUMMARY OF THE INVENTION As described above, the present invention has a large number of parts in the prior art, has a complicated structure, has rattling and cannot be clearly imprinted, is difficult to assemble, and has a noise during use. There was a problem such as large.

[0004]

According to the present invention, in order to solve the above-mentioned problems, in a rotary mark main body X composed of a rotary mark A and a fixed stamp portion B, a standing leg 26 having a holding piece 19 and a rib 24.
The upper end surface of the is integrated with the screw 21.

[0005]

[Function] The leg portion 22 of the rotary mark A and the rib 2 of the fixed stamp portion B
4 and the slit groove 18 prevent rattling of the rotation mark A and the fixed stamp portion B from the front and rear, and the holding piece 19 at the upper end is held by a screw 21 so as to be vertically movable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3. Reference numeral 1 denotes an inner frame, which is box-shaped and has long side legs 5 partially open. A control slit 3 and a guide protrusion 4 are provided inside the control slit 3 in the longitudinal direction substantially at the center of the short side leg 2 of the inner frame body 1. A window 6 which is larger than the print body of the rotary stamp is provided on the lower end surface, and an ink cartridge 7 is held above. Reference numeral 10 denotes an outer frame, which is box-shaped and has a long hole 13 on a short side surface 12. Both the outer frame body 10 and the inner frame body 1 can be slidably moved. 28
Always pushes the outer frame body 10 upward with a coil spring. 14 is an inversion axis. A is a rotation mark. In the rotation mark A, the leg 22 and the bridge piece 31 are integrally formed by bending, the upper end of the leg 22 is bent, and a holding piece 19 having a notch 20 on at least one side is formed. An inversion shaft hole 17 is provided below the leg portion 22, and a rotor shaft hole 16 is provided above the leg portion 22. The inversion shaft hole 17 is slightly larger than the diameter of the shaft 14. Rotor 11 and bridge piece 31 supported by rotor shaft 15
The print belt 30 is stretched between the two, and both ends of the rotor shaft 15 are held in the rotor shaft holes 16 to form the rotation mark A. Next, in the fixed stamp portion B, a screw hole 25 is provided on the upper end surface of one standing leg 26 having the guide groove 23 on the short side leg portion side, the slit groove 18 is provided on the other standing leg 26, and the guide groove is provided. 23
The ribs 24 are provided on the. The guide groove 23, the rib 24, and the slit groove 18 hold the leg portion 22 and prevent rattling when the rotary mark A is inserted into the fixed stamp portion B. On the bottom surface of the fixed stamp portion, the print belt 30 for the rotary stamp A is provided.
A window 29 through which the image can be exposed is provided, and a printing body 27 is attached.

Next, in order to combine the rotation mark A and the fixed stamp portion B, the screw 21 is temporarily tightened in the screw hole 25, and the leg portion 22 of the rotation mark A is inserted along the guide groove 23. Then, one holding piece 19 is further inserted into the slit groove 18, the notch 20 of the holding piece 19 is held by a screw 21, and the screw 21 is further screwed in to make the print belt 30 of the rotation mark A and the print body 27 the same. Fine adjustment to make it flat
Becomes The rotor shaft hole 16 does not necessarily have to be a hole, and may have a cutout shape capable of holding the rotor shaft 15, a bent piece, or the like. Since the notch 20 need only be held by the screw 21, the shape does not matter, so that the notch 20 as shown in FIG.
Alternatively, the holding groove 19 may be omitted and the slit groove 18 may be provided in each standing leg 26. The ink occlusion body 8 of the ink cartridge 7 is made by impregnating a felt, sponge or the like with ink, and is further provided with a knob portion 9.
This is to prevent the finger from being stained with ink when replacing the.

An assembling method in which each of the above components is a reversal type rotary stamp will be described. First, assemble the rotation mark A,
The fixed stamp portion B is integrated to form a rotary stamp main body X. The coil spring 28 is placed on top of the inner frame body 1 and the outer frame body 10
And the guide projection 4 is aligned with the guide groove 23 of the fixed stamp portion B, and the reversing shaft 14 is inserted into the elongated hole 13 of the outer frame body 10, the control slit 4 of the inner frame body 1, and the reversing shaft hole 17, A combination of the body 1, the outer frame body 10, the rotation mark A, and the fixed stamp portion B is assembled. The reversing shaft 14 is held in the elongated hole 13, the control slit 4, and the reversing shaft hole 17 by the coil spring 28. Next long hole 1
From the outside of 3, the end of the reversing shaft 14 is clamped by the knob 32. Next, the ink cartridge 7 is inserted into the inner frame 1 to complete the assembly. If the repulsive force of the coil spring 28 is small, ink cannot be sufficiently adhered 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.

[0009]

As described above, according to the present invention, the leg 22 of the rotary mark A, the guide groove 23, the rib 24, and the slit groove 18 hold the rotary mark A and the fixed stamp portion B to prevent rattling. Since 19 can be finely adjusted up and down by the screw 21, clear marking can be performed without causing noise even when the reversing shaft 14 moves quickly. Since the guide groove 23 is formed in the fixed stamp portion B, it is not necessary to provide the hole for the reversing shaft 14, so that the mold can be manufactured at low cost.
