BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric movable stamping machine having a stamp below.

[0002]

2. Description of the Related Art Conventionally, this type of stamping tool uses a power source such as a motor, and has a stamp attached below by using a movable arm, a combination of an arm and a gear, or an electromagnet. Is moved up and down to perform the sealing operation. In these applications, for example, the one by arm movement is (A)

No. 60 and (c) Japanese Utility Model Application Laid-open No. 62-58661.
In addition, those using lifting devices such as electromagnets are (d)
4-52917 exists. (A), (b), (c)
The application uses a motor as a power source, and as a characteristic of the motor, the rotation speed is fast and there is no torque, so a number of arms are used to reduce the rotation speed, increase the torque and use it for lifting and lowering the stamp. ing. The application (d) uses an electromagnet, and the adjustment of the ascending / descending speed and the torque is performed by the number of turns of the coil and the voltage. In particular, the application (d) has a completely different configuration from the present invention. As a problem of these applications, in order to smoothly raise and lower a constant pressure and a constant speed for the stamping operation, a large number of arms are required, and a transformer or the like must be used. For this reason, a large space is required, resulting in an increase in size. A method of arranging the gears in parallel with the axis H is also conceivable. However, this method also requires a large number of gears to be arranged at a constant pressure and a constant speed for the marking operation, which requires a large amount of space. As a result, the size becomes large.

[0003]

[Problems to be Solved by the Invention] As described above, the conventional problem is that the power of a power source such as a motor is smoothly moved up and down at a constant pressure and a constant speed for a stamping operation, and a number of parts (for example, an arm) , Transformers, and gears), which requires a lot of space and results in an increase in size. It is therefore an object of the present invention to provide an electric marking tool having a compact mechanism capable of smoothly attenuating the number of revolutions of a power source such as a motor and vertically moving a stamp face.

The rotor 6 is provided with the three shafts 7 on the upper surface, and the transmission teeth 8 are provided so as to protrude from the lower end surface of the holding body 4. The transmission teeth 8 mesh with the small gear 3a. Here, it is desirable that the rotor 6 be rotatable inside the holder 4 and fixed so as not to move left, right, up and down. For example, a circular rib 21 is provided around the hole 20, and a groove 2 provided in the rotor is provided.

The spring 13 resiliently supports the fixed shaft 12 to push it upward. A concave portion 11 is provided on the upper surface of the fixed shaft 12, and is in contact with the convex portion 10 when the stamp surface is stored above the lower end surface of the main body 15. Next, in order to make the stamp face protrude from the lower end face, the transmission rotor 9 is rotated so that
The contact between 0 and the recess 11 is released. A stamp 14 is removably fitted and fixed below the fixed shaft 12. Here, the seal 14 is a self-supply type ink having a porous printed body, but may be a non-porous one such as a general rubber stamp. Next, the laminated unit A and the main body 15 are fixed by the bolts 23 and the nuts 24, and further covered by the exterior body 25 including the motor, the battery, and the switch.

The method of using and operating the electric stamping machine of the present invention is as follows.

When the motor 1 starts rotating by the switch, the gear 2 attached to the tip of the motor 1 rotates, and the small gear 3 meshing with the gear 2 meshes with the inner ring teeth 5 provided on the inner wall surface of the holding body 4 and rotates. The child 6 is rotated. The rotation direction at this time is such that the small gear 3 rotates in the opposite direction to the gear 2, and the rotor 6 rotates in the same direction as the gear 2. Next, the transmission tooth 8 provided below the rotor 6 rotates the small gear 3a meshing with the transmission tooth 8, and the small gear 3a meshes with the inner ring tooth 5a.
Rotate a. The rotation direction at this time is the same as that of the small gear 3, the gear 2, and the rotor 6. Here, assuming that the small gear 3, the rotor 6, and the holder 4 are a unit A, the rotors 6 of the stacked unit A are sequentially rotated, and the transmission rotor 9 meshing with the transmission teeth 8 of the lowermost unit A is rotated. Rotate.

However, when it is in contact, the stamped surface of the stamp 14 attached below the fixed shaft 12 which is resiliently supported upward by the spring 13 is not exposed from the lower end of the main body 15. However, when the transmission rotor 9 rotates, the contact between the convex portion 10 and the concave portion 11 is released, and the convex portion 10 comes into contact with the upper surface of the fixed shaft 12 and pushes the fixed shaft 12 downward to push the stamped surface from the lower end of the body 15. Exposed. Next, in order to store the stamped surface, the transmission rotor 9 is further rotated to bring the convex portion 10 and the concave portion 11 into contact with each other, thereby returning to the original state.

[0010]

[Effects] The present invention has the above-described configuration, and therefore the following effects can be obtained. Since the gears can be arranged perpendicular to the axis H and the rotational force of the motor can be adjusted, the cylindrical stamp itself can be effectively used, and the compact can be achieved. Since all the gears can be rotated in a direction perpendicular to the axis, loss of the rotational force of the motor can be reduced. (Conventionally, since the rotational force is converted from vertical to parallel, and further vertically, the loss is large.)
