Abstract

PURPOSE: To obtain a deformable stamp capable of freely altering a shape of a rugged surface of the stamp by forming the stamp with a bundle of slender bars. CONSTITUTION: A rugged surface like a stamp is formed by pushing or retracting only a designated bar of a bundle 1 of slender bars like several fibers, or wires under electric or mechanical control, temporarily fixed, and impressed at any place at any time by a conventional procedure. As the electric control, a modified head of a conventional dot matrix printer, a piezo unit, or a stepping motor and a magnetic head of components of a magnetic disk drive are modified and applied. Thus, a character string or pattern formed of a computer or another input unit is copied by a stamp, the stamp is used at another plate at another time to copy the same string or pattern as that of the original on format or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention allows the shape of the uneven surface of a seal to be freely changed. Conventional seals could be selected from a single pattern or fixed characters or patterns. Therefore, conventional seals and rubber stamps are convenient for fixed usage, but they cannot immediately respond to temporary applications or unexpected new demand. Or, although there are portable copiers and printing machines, they are not as good as seals in terms of usability and portability. In particular, the seal is less suitable for the format. The present invention is a bundle of elongate rods, such as some fibers or wires, that is electrically or mechanically controlled to extrude or retract only the designated rods in the bundle to form a stamped surface. Then, once fixed, you can imprint it anytime, anywhere in the same way as a conventional seal. The electrical control may be applied by modifying the head of a conventional dot matrix printer, or by applying a piezo measure, or modifying the stepper motor and magnetic head that are parts of the magnetic disk drive. An electric control unit and a seal can be integrated. As a method of fixing the bundle of rods so that the pattern does not change while using it as a seal, a method using mechanical pressure, a method using a memory metal, or a method using electricity, electromagnetism, or piezoelectricity may be used. According to the present invention, a character string or pattern created by a computer or other input device can be copied to a seal, and the same character string or pattern can be copied to a format or the like using the seal at another time or another place. I can do it.
Note that, unlike a printing machine or a copying machine, the present invention can be stamped using an ordinary stamp stand or vermilion.
