Claims
- 1. A camera, comprising:
- a power source;
- boosting means for boosting a voltage of said power source;
- charging means for accumulating therein energy boosted by said boosting means;
- piezo-electric means;
- driven means including a shutter connected to be actuated by said piezo-electric means;
- driving and controlling means for driving and controlling said piezo-electric means by energy accumulated in said charging means; and
- exposure controlling means for controlling said driving and controlling means to cause a charged voltage of said charging means to be applied to said piezo-electric means in a first polarity in order to order to said shutter and in a second polarity opposite to the first polarity in the course of the closing operation of said shutter.
- 2. A camera, comprising:
- a power source;
- boosting means for boosting a voltage of said power source;
- charging means for accumulating therein energy boosted by said boosting means;
- piezo-electric means;
- driven means including a shutter connected to be actuated by said piezo-electric means;
- driving and controlling means for driving and controlling said piezo-electric means by energy accumulated in said charging means;
- operating means manually operable releasing said shutter and for producing a manual operation signal; and
- controlling means operable in response to said manual operation signal for causing a predetermined voltage to be applied to said piezo-electric means to set said piezo-electric means to a predetermined initial position.
- 3. A camera according to claim 2, wherein said operating means includes a manually depressible shutter release button, means for producing said manual operation signal in response to depression of said shutter release button to a first position, a d means for producing a photographing starting instruction signal instructing starting of a photographing operation in response to depression of said shutter release button to a second position.
- 4. A camera according to claim 2, wherein said controlling means causes a voltage of a same polarity to that of a voltage applied to said piezo-electric means in order to open said shutter to be applied to said piezo-electric means.
