    摘要： An impact type piezoelectric actuator moves a driven member reciprocally by charging and discharging a piezoelectric device at different charging and discharging speed corresponding to moving direction. When a moving speed of the driven member is supposed to be slower than a predetermined threshold speed due to drop of voltage of a battery or drop of an ambient temperature, a controller drives the piezoelectric actuator in a manner to increase expansion and contraction of the piezoelectric device. Alternatively, when the moving speed of the driven member is supposed to be equal to or higher than the predetermined threshold speed, the controller drives the piezoelectric actuator in a manner to decrease the expansion and contraction of the piezoelectric device for saving the electric power consumption of the battery.

    摘要： A camera, which uses a film cartridge having a film exposure status display, comprises an E2PROM. The E2PROM stores the fact that the film status determination operation is underway when film status determination operation is underway. When a power supply is removed while the film status determination is operating and then the power supply is mounted, the camera operates an initial process. The film exposure status display is set in `exposed` because the E2PROM holds that the film status determination operation is underway. A camera is .provided that deems the film in the film cartridge to have been exposed and does not perform exposure if the power supply is cut off while the determination of the film status of the film in the film cartridge mounted in the camera is underway.

    摘要： A camera system comprises an operation member provided in an interchangeable lens adapted to be manually operated; signal sending circuit for sending a signal in response to the manual operation of the operation member; and a controller provided in a camera body which is adapted to switch between an operative state where a predetermined operation is executed and a halt state where the controller is halted after completion of the predetermined operation. The controller switches from the halt state to the operative state in response to the signal from the signal sending circuit to execute the predetermined operation. According to the camera system, since the system controller in the camera body is actuated in response to the operation of the operation member on the lens side, a camera which can substantially instantaneously respond to a request on the lens side can be realized.

    摘要： The present invention provides a device and method for enabling the writing of a print format and a trimming magnification onto a film surface using a simple construction. Film information comprising a print format set using a format setting switch 10 and a trimming magnification set using a trimming setting switch 11 is converted into three-bit data by a data conversion circuit 26 inside a controller 25. This information is input to an LED light emission controller 27. Photoemitter elements 17 and 18 are located in the feeding path for the top and bottom edge areas of the film F, and a LED light emission controller 27 causes the photoemitter elements 17 and 18 to emit light during a series of image recording operations, whereby the film information is written onto the top and bottom edge areas of the film F. By optically writing the print format information and the trimming information onto the film F, both items of information can be easily written onto the film surface without making the device complex.
