STAMP-FACE PLATEMAKING DEVICE, MEDIUM HOLDER, AND MEDIUM HOLDER MANUFACTURING METHOD

摘要

A stamp-face platemaking device transports a medium holder inserted into a plate insertion portion to a printing unit. The medium holder holds a stamp face material in a plate-like member, and has a predetermined pattern in a side end portion thereof. An optical sensor detects the top end portion of the medium holder on a sensor scanning line in the inserting direction, and the pattern start point and the pattern end point of the predetermined pattern. At least one of the horizontal and vertical sizes of the stamp face material is set based on the positions of two of the detected end portions. When the pattern end point is detected, platemaking with the stamp face material is started.

主权项

1. A stamp-face platemaking device comprising:
a plate insertion portion; a pattern detecting unit configured to detect respective positions of a top end portion of a medium holder on a sensor scanning line in an inserting direction, one pattern end portion of a predetermined pattern, and the other pattern end portion of the predetermined pattern when the medium holder holding a stamp face material and having the predetermined pattern formed in a side end portion thereof is inserted into the plate insertion portion; and a size setting unit configured to set at least one of a size of the stamp face material in the inserting direction and a size of the stamp face material in a direction perpendicular to the inserting direction based on the positions of at least two end portions among the top end portion on the sensor scanning line, the one pattern end portion, and the other pattern end portion detected by the pattern detecting unit.
