Abstract
PURPOSE:To enable the goodness or not of operation condition to be checked with simple constitution by comparing the detection signal of the operating sound of the mechanisms which are operating time-serially, with the reference signals corresponding to the normal operations of said mechanisms. CONSTITUTION:The control signals from a control circuit incorporated into a camera are sent to each part of the camera time-serially, to operate respective mechanisms; at the same time, these are sent to a conversion circuit and are sent as a series of synchronizing reference signals to a comparator. If there is a time lag in the operating member, a required delay is applied in the conversion circuit. On the other hand, a detector such as small microphone, electrostrictive or magnetostrictive element or the like is mounted of operating sound is sent to the comparator. By the comparison of both signals, the operation of the camera is stopped or the abnormal section is displayed. Thereby, the goodness or not of the operation may be checked with the simple constitution.
