BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inversion type stamp which has an ink pad on the top of a stamp body and inverts and prints a printed body by 180 degrees.

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-63-262280, JP-A-1-21
No. 8881 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. By the way, when the ink in the ink pad is low and the amount of ink to be transferred to the print body is small, the ink pad is refilled with an appropriate amount of ink. There was a drawback in that the hands and seals were stained with ink, or the ink was replenished in a large amount, resulting in stains due to ink leakage. To solve these issues,
U.S. Pat. No. 4,432,281 discloses that the cover member 4b is removed and the operating member 4 is pushed to replenish the ink from the hole 25. When the ink to be replenished is injected into the hole, the operating member is pressed against the coil spring with one hand. There is a disadvantage that must be pressed. U.S. Pat. No. 4,841,860, JP-A-63-262280, and JP-A-1-218883 have a structure in which an ink pad is detachable from a side surface of a stamp. When the ink pad is attached / detached, the surface of the print body is rubbed.
There is a disadvantage that the ink on the surface of the ink pad after ink replenishment is rubbed off and stained by the printed body. US Patent 497
No. 0954 has a structure in which the spring 16 is fixed to the cap 54 when the cap 54 of the outer housing 10 is removed, so that the ink pad is easily attached and detached. Cup 5
2, 53 are inserted individually and the cap is fitted to the outer housing. Therefore, the cap is fitted while the spring is entangled with the spring holding cup at the edge, or the spring is twisted when the cap is removed, and the spring is removed. There is a disadvantage that it cannot be used as a stamp because it is deformed.

SUMMARY OF THE INVENTION As described above, the present invention makes it easy to attach and detach the ink pad when refilling the ink pad in the conventional technique, and does not deform the coil spring and uses the ink. Provided is a reversible stamp that can be replenished without soiling hands and stamps, and that can be easily replaced even when the color of an ink pad is exchanged.

[0003]

According to the present invention, in order to solve the above-mentioned problem, a vertical plate 30 is provided from a top plate of the operation unit 17, and a spring 20 is held by a spring holder 26 provided with a guide piece 28. .

[0004]

Since the spring holder is held by the vertical plate 30 of the operation unit 17 with the guide piece 28 so as to be able to move up and down and the spring 20 is always held by the operation unit 17, ink replenishment can be performed without deforming the spring 20. Can be.

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 is open at the top and bottom. An elongated hole 3 is provided substantially vertically in the center of the short side leg 2 of the inner frame 1 and a swing projection receiver 4 is provided above the elongated hole. Reference numeral 5 denotes an outer frame, which is open up and down like the inner frame 1. A hole 7 is provided below the short side wall 6 of the outer frame 5. Reference numeral 10 denotes a stamp body, to which a printed body 11 is attached. Vertical guide grooves 31 are provided on both sides of the stamp body 10. Reference numeral 13 denotes a control plate, which includes a swing projection 16 and a swing projection 1
A guide projection 15 and a control slit 14 are provided on the side opposite to 6. The swing projection 16 is inserted into the swing projection receiver 4 of the short side leg 2 of the inner frame 1 to hold the control plate 13 swingably, and the guide projection 15 is inserted into the vertical guide groove 31. Then, the reversing shaft 12 was passed through the stamp main body 10, the control slit 14, and the elongated hole 3, and was fitted and held in the hole 7. Seal subject 10
Are rotatably held on the reversing shaft 12. Reference numeral 17 denotes an operation unit. It was a box-like body with one open side, and the open part was detachable from the outer frame body 5 as shown in FIG. An inverted T-shaped groove 9 is provided inside the long side wall 8 of the outer frame body 5, and a tongue piece 21 having a claw 22 is hooked on the inverted T-shaped groove 9 on the operation portion 17 to integrate them. When the two parts are to be separated from each other, the tongue piece 21 of the operation part 17 is pressed near the tongue piece 21 to remove the tongue piece 21 from the inverted T-shaped groove 9. This detachable configuration may use a commonly used configuration. A spring holder that is provided with a vertical plate 30 whose distal end has an inverted T-shaped cross section from the top plate of the operation unit 17, and that the vertical plate 30 can be vertically movably held by a guide piece 28 whose distal end is not detached. At 26, the spring 20 is held in the operation unit 17. The spring holder 26 includes a spring receiving portion 27 and a hole 29.
Is provided. When the operation unit 17 and the outer frame 5 are integrated, the ink pad 23 is pressed and fixed to the inner frame 1 by the spring 20. The ink pad 23 is made by impregnating an ink into an ink occluding body 24 such as a felt.
The projection 25 is detachably fitted into the hole 18 of the spring holder 26. Note that the ink pad 2 is used instead of the convex portion 25.
A knob may be provided at a position which does not come into contact with the guide piece 28 at 3.

[0006] An assembling method using the above components as stamps will be described. The control plate 13 is held by the inner frame body 1, the guide projection 15 is inserted into the vertical guide groove 31 of the stamp body 10, and the reversing shaft 12 is passed through the slot 3, the control slit 14, and the stamp body 10 in order. The inner frame 1 and the outer frame 5 are integrated into the hole 7 of the body 5 to be held. On the other hand, after the spring 20 is mounted on the cylinder 19 of the operation unit 17 and the spring is inserted into the spring receiving portion 27 of the spring holder 26, the guide piece 28 is held on the vertical plate 30 and the spring 20 is integrally held on the operation unit 17. Is done. When the ink pad 23 is placed on the inner frame 1 and the operation unit 17 is fitted to the outer frame 5, the seal shown in FIG. 1 is obtained. Print body 1 of stamp body 10
1 is in contact with the ink pad 23 at all times by the repulsive force of the spring 20, so that the ink adheres to the print body 11. If the repulsive force is 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 11.

[0007]

As described above, according to the present invention, the spring holder 26 is integrated into the operation unit 17 by the guide piece 28. Therefore, when the ink pad 23 is replaced or ink is refilled, the operation unit 1 is not used.
When the 7 is separated from the outer frame body 5, the spring 20 is housed inside the operation unit 17, and the reassembly is easy,
In addition, since a force such as a twist is not applied to the spring 20 when the operation unit 17 is attached or detached, the spring force does not change, so that clear stamping can be always performed.
