Abstract: 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.

Abstract: 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.

Abstract: A camera has a release button, a shutter which operates upon depression the release button, light emitting diode that emits light used to record information on the film, a power source, a switch that closes in response to the operation of the release button to provide power to the light emitting diode, the switch having a first contact point connected to the power source and a second contact point connected to the light emitting diode, and a selecting member movably supported between a first position at which the selecting member prevents the closing of the first and second contact points and a second position at which the selecting member does not prevent the closing of the first and second contact points.

Abstract: A camera (100), suitable for using photographic film (18) with a magnetic track (33), includes a transporting mechanism (M, 22) for transporting the film along a film transport path, a magnetic head (11) positioned adjacent the film transport path so as to read information magnetically recorded on an adjacent portion of the magnetic track, signal processing circuits (12, 42) to provide a digital output signal responsive to thus read information, and a microcomputer (13) for comparing a digital output signal to predetermined threshold levels in order to determine whether or not information is recorded on the portion of the magnetic track being read by the magnetic head and for setting the threshold values. The threshold levels can be set in accordance with a level of the digital output signal when magnetically recorded information is not being read by the magnetic head, e.g., before the film is fed or during the feeding of the film before the first frame reaches the magnetic head.

Abstract: A camera is detachably mountable with a film cartridge which is provided with a photographic film having a number of successive frames and a film state indicator operable to indicate an exposed state that the film is already exposed, and includes: a film feeding device which feeds the film in a first direction and in a second direction opposite to the first direction; a recording device which records a specified data on the film when the film is being fed in the first direction; a judging device which judges whether the specified data is recorded on the film when the film is being fed in the second direction; and a setting device which is responsive to the judging device and associated with the film state indicator of the film cartridge, and is operable to cause the film state indicator to indicate the exposed state when the specified data is judged not to be recorded on the film.

Abstract: 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.
