Classification: G03B

Abstract:
A camera having a device for detecting an abnormality of a driving mechanism, comprising:driving-condition detection means for detecting a driving condition of a driving mechanism thereof to generate an output value;storage means for storing a first output value of the driving-condition detection means which is in a normal state;impact detection means for generating an output upon detecting an impact applied to the camera;means responsive to said impact detection means detecting an impact for operating said driving mechanism after detection of said impact and controlling said driving-condition detecting means to generate a second output value representing a driving condition of said driving mechanism subsequent to said impact;comparison means for comparing said first output value stored before occurrence of said impact, which is preliminarily stored in the storage means, of the driving-condition detection value of a normal state, with said second output value; andabnormality detection means for detecting whether an abnormality has occurred according to a result of a comparison made by the comparison means and for generating a signal representing an abnormal condition when an abnormal condition occurs.
