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, when assembling these reversible stamps, a control plate for reversing the stamp is held by the inner frame, and the reversing shaft is fixed to the outer frame.
However, at that time, the control plate cannot be temporarily held on the inner frame. U.S. Pat. No. 4,432,281 holds the pivot post 45 of the lever 44 until the assembly is completed, so that it is difficult to handle because the lever 44 is detached during the assembly, and that the lever 44 is not the same shape on the left and right, so that it can be used erroneously. There are drawbacks in assembly. Also, the number of parts was two and the cost was increased. US Patent No. 4
In order to solve the above-mentioned problems, Japanese Patent Application Laid-Open No. 842860 and Japanese Patent Application Laid-Open No. 1-218881 solve the problem of assembling by connecting the connecting piece 14, but the swing projection 17 must be integrated with the tongue piece 16. This is an invention for solving the difficult-to-assemble problem, and has disadvantages such as an increase in die production cost and breakage of the tongue piece 16 during assembly. Further, since the contact piece 14 is located in the gap between the ink pad 11 and the spring holding portion, the height of the entire stamp is increased, and there is a disadvantage that the entire stamp is larger than the size of the stamp face. US Patent 4970
No. 954 has the same drawbacks as the aforementioned US Pat. No. 4,432,281. In addition, if the control plate is not connected with the connecting member, the stamp body is difficult to reverse unless the play between the slit and the reversing axis is large, and the control plate is connected near the swinging projection. When connected by a member, a load is applied to the swing projection in the axial direction, and the control plate becomes difficult to move, so that the play between the slit of the control plate and the reversing shaft must be large. For this reason, there is a disadvantage that the sound produced by the backlash is large at the time of stamping and the stamp must be improved.

[0002]

SUMMARY OF THE INVENTION As described above, the present invention is difficult to assemble due to mistakes in assembly in the prior art, and that the size of the stamp is larger than that of the stamp face, and that the present invention can be used at low cost. Provide a reversible stamp that can reduce the sound of time.

[0003]

The present invention is characterized in that the guide projection 15 of the control plate 13 is connected to the guide projection 15 of another control plate 13 by a connecting member 18 in order to solve the above-mentioned problem. And

[0004]

When the control projection 13 is connected to the control plate 13 by the connection member 18, the swing projection 16 is mounted on the swing projection receiver 4.
The connecting member 18 becomes a spring and can be easily mounted, and is securely held after the mounting.

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 is a swinging projection 16 upward, a guide projection 15 on a side opposite to the swinging projection 16, and a control slit 14.
Are provided, and the guide projections 15 are connected by a connecting member 18. The swing projection 16 is inserted into the swing projection receiver 4 of the short side leg 2 of the inner frame body 1, the control plate 13 is swingably held, and the guide projection 15 is inserted into the vertical guide groove 31. At the same time, the reversing shaft 12 is moved to the stamp main body 10, the control slit 14,
The long hole 3 was penetrated, and fitted and held in the hole 7. Seal subject 1
0 is rotatably held on the reversing shaft 12. The cross-sectional shape of the connecting member 18 can be appropriately selected depending on the size of the printed body, such as a circle, a plate, or a triangle. 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. Inverted T-shaped groove 9 inside long side wall 8 of outer frame 5
And a tongue piece 21 having a claw 22 is attached to the
The two are integrated by hooking in the groove 9. 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. 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 in the operation unit 17. The ink pad 23 is made of an ink occluding material 2 such as felt.
4 is impregnated with ink, and further provided with a knob 25 to prevent the finger from being stained with ink when the ink pad 23 is replaced.

[0006] An assembling method using the above components as stamps will be described. The connecting member 18 of the control plate 13 is slightly deflected to the inner frame 1, and the swing projection 16 is
And the guide protrusion 1 is inserted into the vertical guide groove 31 of the stamp main body 10.
5 and the reversing shaft 12 is inserted into the slot 3, the control slit 14,
The inner frame 1 and the outer frame 5 are integrated with each other by sequentially penetrating the stamp main body 10 and fitting into the holes 7 of the outer frame 5. On the other hand, when the spring 20 is mounted on the cylinder 19 on the operation unit 17, the ink pad 23 is placed on the inner frame 1, and the operation unit 17 is fitted on the outer frame 5, the stamp shown in FIG. Print body 11 of stamp body 10
Is always in contact with the ink pad 23 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 becomes 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 printing body 11.

[0007]

[Effect] As described above, the present invention is directed to the guide projection 1 of the control plate 13.
Since the connecting members 18 are connected by the connecting member 18, the connecting member 18 can bend like a spring when the control plate 13 is mounted on the inner frame 1, so that the mounting can be performed reliably and easily. In addition, since the size of this type of stamp can be made smaller than that of the conventional stamp, it can be manufactured at low cost. Since the control plate 13 is held on the inner frame body 1 by the connecting member 18 and the swing projection 16, the movement of the reversing shaft 12 is reliably linked, and the play between the control slit 14 and the reversing shaft 12 can be reduced. The sound of time can be reduced.
