TABLE RAISING/LOWERING DEVICE

摘要

PROBLEM TO BE SOLVED: To use a paper sheet amount sensor for detecting a limit position in the uppermost part or the lowermost part of the table. SOLUTION: The sensor 11 detects an actuator 10 attached to a member 7 rotating according to the height of the table 2 so as to detect positions by sensors fewer than the number of the positions of the paper sheets amount to be detected. This constitution can detect not only the paper amounts on the table but also the limit position in the uppermost part or the lowermost part of the table.
