DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing rotary stamp having an ink pad on a rotary stamp in which a rotary stamp and a fixed stamp are integrated, and inverting the rotary stamp by 180 degrees for printing.

2. Description of the Related Art Inverting rotary stamps of this kind are well known in U.S. Pat. Nos. 1,730,365 and 2,790,080, German Patent 379,552, Japanese Patent Application Laid-Open No. 61-89080, and the like. 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 in contact with a coil spring, and at the time of stamping, the rotary stamp is reversed by almost 180 degrees and stamped. .
However, the rotary stamp and the fixed stamp are securely fixed with no looseness, and clear printing cannot be performed unless the printing surface of the rotating stamp and the printing surface of the fixed stamp are flush with each other. Configuration is required. In other words, the configuration of fixing and fine adjustment is an essential requirement, but they are contradictory, so that the configuration is complicated.

In US Pat. No. 1,730,365, the fine adjustment is made with the screw 40, so that the configuration of the fixed stamp portion is complicated, the cost is increased, and a clearance is required between individual parts. Noise occurs when used. In Japanese Patent No. 2079080, the rivet 59 is used for fixing and the knob 88 is used for fine adjustment. However, the number of parts is increased and the configuration is complicated. German Patent No. 379552 and JP-A-61-8
No. 9080. In this application, the hole 17 of the fixed stamp portion must be formed, which complicates the mold structure. Further, the rattle of the rotary stamp portion and the fixed stamp portion is fixed by the hole 17 of the fixed stamp portion and the shaft 9. , And must be fixed with screws 16. The reason that these known arrangements must be robust is that the reversing rotary stamp rotates 180 degrees about the reversing axis, so the rotational speed is faster than it appears. Furthermore,
Since the pressure is applied against the coil spring, the printing pressure at the time of printing must be high. In order to satisfy these conditions,
Making fine adjustments with screws is well known in the art, and it is easy and reliable to reduce the pitch of the screws.
However, there has been a demand for a seal which can be firmly held between the rotary stamp portion and the fixed stamp portion, has no rattling at the time of stamping, has little noise, is light at the time of assembly, and can be easily stamped at the time of assembly.

[0003]

SUMMARY OF THE INVENTION As described above, according to the present invention, the prior art has a large number of parts, has a complicated structure, has rattling, cannot be clearly marked, is difficult to assemble, and has a noise during use. Is large.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 denotes an inner frame, which is box-shaped, and the long-side leg 5 is partially open. A control slit 3 is provided substantially vertically in the center of the short side leg 2 of the inner frame 1 and a guide projection 4 is provided inside the control slit 3. The lower end face is provided with a window 6 which is larger than the rotary stamp printing body, and holds an ink cartridge 7 above. Reference numeral 10 denotes an outer frame, which is box-shaped and has a long hole 13 formed in the short side surface 12. The outer frame body 10 and the inner frame body 1 can both slide and move. 28
Is a coil spring that constantly pushes the outer frame body 10 upward. 14 is an inversion axis. A, is a rotation mark. The rotation mark A is obtained by bending and forming the leg 22 and the bridge piece 31 integrally, and bending the upper end of the leg 22 to provide the holding piece 19.
In both cases, a notch 20 is provided in the holding piece 19,
A reversing shaft hole 17 is provided in the upper part, and a rotor shaft hole 16 is provided in the upper part.
Between the rotor 11 supported by the trochanter shaft 15 and the bridge piece 31
The printing belt 30 is stretched around the
By being held in the trochanter shaft hole 16, the rotation mark A becomes
You. The reversing shaft hole 17 is slightly larger than the diameter of the shaft 14.
Comb. Next, the fixed stamp portion B is provided with a screw hole 2 in the upper end surface of one of the standing legs 26 having the guide groove 23 provided on the short side leg side.
5, the other standing leg 26 is provided with the slit groove 18, and the guide groove 23 is provided with a rib 24. The guide groove 23 and the rib 24 and the slit groove 18, when the rotating indicia A is inserted into the fixing stamp part B, and prevent rattling holding the legs 22. On the bottom surface of the fixed stamp portion B, there is provided a window 29 through which the printing belt 30 of the rotary stamp A can be exposed, and a printing body 27 is attached.

[0007] Then, the rotary stamp by combining the A and the fixed stamp unit B assembles rotary stamp principal X To a screw 21 temporarily fastened to the screw hole 25, fixing the legs 22 of the rotary stamp A stamp
Inserting along the guide groove 23 of the part B , further inserting one holding piece 19 into the slit groove 18,
A notch 20 is held by the screw 21, the screw 2 in this condition
1 is further screwed, and the printing belt 30 of the rotation mark A and the fixing mark are fixed.
Fine adjustment so that the print body 27 of the stamp unit B on the same plane
Thus, the assembly of the rotation mark main body X is completed. still,
The rotor shaft hole 16 does not necessarily need to be a hole, and may be a cutout shape, a bent piece, or the like that can hold the rotor shaft 15. Notch 20 is shaped rather by if it is held in the screw 21 questions
For this reason, as shown in FIG. 4, the holding piece 19 without the notch 20 may be provided, and the slit groove 18 may be provided on each of the standing legs 26 as shown in FIG. The ink occluding body 8 of the ink cartridge 7 has a felt, a sponge, or the like impregnated with ink, and further has a knob 9 to prevent a finger from being stained with ink when the ink cartridge 7 is replaced.

A method of assembling each of the above components as a reversible rotary stamp will be described. First, assemble the rotation mark A,
The rotation mark A and the fixed stamp portion B are integrated to form a rotation mark
Assemble X. A coil spring 28 is provided above the inner frame 1.
And the outer frame 10 is covered, and the guide groove 23 of the fixed stamp portion B is placed.
Rotary stamp combined guide projections 4, an inverted shaft 14 elongated hole 13 of the outer frame member 10, the inner frame member 1 of the control slit 3 by inserting the inversion shaft hole 17 of the rotating indicia A, the inside of the inner frame 1 to the Incorporate subject X. The reversing shaft 14 is held by the coil spring 28 in the long hole 13, the control slit 3 , and the reversing shaft hole 17. Next, slot 13
The end of the reversing shaft 14 is clamped by the knob 32 from outside.
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, the adhesion of the ink is insufficient and clear printing cannot be performed. Therefore, the strength of the spring is determined based on the contact pressing force per unit area of the printed body.

[0009]

EFFECT As described above, the present invention is a backlash of rotary stamp A and the stationary stamp unit B by holding the legs 22 of the rotary stamp A at Guide <br/> Id groove 23 and the rib 24 and the slit groove 18 It is possible to finely adjust the holding piece 19 up and down with the screw 21 , so that clear stamping can be performed without causing a fast movement of the reversing shaft 14 and noise. A guide groove 23 is provided in the fixed stamp portion B.
And a hole through which the reversing shaft 14 passes is provided in the fixed stamp portion B.
Since it is not necessary, the mold can be manufactured at low cost.
