Paper sheet counting machine provided with safety device

摘要

There is proposed a paper sheet counting machine provided with a safety device, the machine including a paper sheet counting mechanism and a double-leaf type sound-proof covers made movable between an open position to gain easy access to said counting mechanism and a closed position at which said sound-proof covers extend above the section containing said counting mechanism. The safety device is constructed such that the closing movements of the sound-proof covers are stopped if an obstacle is present adjacently or engaged with the edge faces of the sound-proof covers. The safety device comprises an obstacle detecting member and a control circuit responsive to a signal generated from said obstacle detecting member for generating a signal to stop the closing movements of the sound-proof covers, or alternatively it comprises a control circuit including a timer.
