Abstract
A stamp unit 1 comprises a holder 4 which is to be set in a holder storage part 70 of a stamp manufacturing device for making a stamping surface on a stamp material 3 held in the holder 4. When the holder 4 is set in the storage part 70, the cam effect is generated between the positioning projection 77 of a fixing member 71 and a slant recess 43 of the holder 4, thereby positioning the holder 4 to a predetermined stamp making position in the storage part 70. In a state where the holder 4 is positioned in place, microswitches 75A and others disposed near the projection 77 of the storage part 70 are selectively turned on and off by cooperation between detection recesses 44 and a peripheral wall 38 of the holder 4, so that the existence and the type (size) of the holder 4 are detected.
Claims5
A stamp unit utilizable in a stamp manufacturing device with a storage part where detection switches are arranged, comprising:
- a holder member disposed vertically slidably;
- a stamp member held at a lower end of the holder member;
- a grip member disposed above the holder member, for moving the holder member downward;
- a positioning projection formed in the storage part where the detection switches detect the holder member set therein;
- a positioning recess formed, in a substantially center position of the side wall of the holder member, in an inward wedged shape with two flat surfaces sloping toward an inside of the holder member, the two sloped surfaces providing a cam member and a cam effect in cooperation with the positioning projection, and the positioning recess positioning the holder member in the storage part due to the cam effect;
- and
- activation and inactivation sections formed in the holder member close to the positioning recess, the sections causing the detection switches to selectively turn on or off in a state that the holder member is positioned in the storage part by the positioning recess.
