摘要： A camera which prevents accidents which could lead to damage to the shutter when performing shutter time tests in the opened state of the back cover of a camera. The camera has a shutter to limit the exposure time of the recording medium which has been loaded, a measurement unit to measure, according to the action of the shutter, the time of the exposure to the recording medium which the shutter performs, and a back cover sensor to detect whether the back cover is open or closed when film or another recording medium has been loaded into the camera. The action of the measurement unit is inhibited when the back cover sensor detects that the back cover is open. The camera also has a drive unit for recording an image on the film or recording medium and a mode selection switch to select between a normal mode in which a photographic action is performed, in which the shutter and the drive unit are activated, and a test mode in which the shutter and the measurement unit are activated but not the drive unit. A shutter control unit may be used during testing so that the shutter is initially activated for an exposure time other than the minimum exposure time, when the shutter performs an exposure of the recording medium.

摘要： There is disclosed a driving device for piezoelectric actuator, in which a voltage is applied to a piezoelectric actuator to generate a mechanical deformation therein, thus actuating a mechanical system. In an aspect, the piezoelectric actuator is at first given a voltage of inverse polarity, for generating a displacement in an opposite direction, and then given a voltage of forward polarity, for generating a displacement in the normal functioning direction, thereby actuating the mechanical system. Displacement and acceleration become larger, as the displacement of the actuator takes place from a position in the inverse direction. In another aspect, the electrical insulation state of the piezoelectric actuator is detected, and, if deteriorated, the destruction of insulation is prevented by an alarm generation and/or inhibition of voltage application. In an embodiment, the insulation state is identified from the ambient humidity of the actuator. In another aspect, if the detected humidity is at a high level that may induce destruction of insulation, the piezoelectric actuator is driven with a low voltage, in order to dehumidity by heat generation. Also shutter control devices for camera, utilizing piezoelectric actuator, are disclosed.

摘要： A shutter of a camera is provided with a shutter trip detecting device includes LEDs and PTRs. Measured are tripping timings of leading and trailing curtains for admitting and intercepting object light to an aperture. An exposure time on a film and a tripping time (curtain velocity) of each curtain are thus detected. The detected result is compared with a fiducial value, and an alarm is given according to the need. There are detected mechanical fluctuation elements relative to the shutter, e.g., a scatter of the exposure time on the film, a partial uneveness of the exposure time and an influence on the exposure time due to a fault in a driving mechanism. The alarm can be thus given to the user, and an automatic adjustment can be made. The shutter trip detecting device includes the shutter leading/trailing curtains, the LEDs and PTRs which detect tripping thereof.

摘要： A camera having a mechanism to determine the precise times at which a shutter or shutter blinds open or close an aperture. The camera measures the actual time in which shutter blinds pass over the aperture by utilizing a projection unit, positioned on one side of the shutter, to project a signal towards the aperture. A signal receiving unit is placed on the other side of the shutter and receives the signal. The output of the signal receiving unit changes depending on whether the signal projected by the projection unit is blocked by the shutter (when the shutter is closed) or whether the projected signal passes through the aperture. The projection unit and the receiving unit can also be placed on the same side of the shutter, with a reflecting unit placed on the other side of the shutter, with the shutter blinds having a different reflectivity than the reflecting unit. When the shutter blinds are closed, the projected signal is reflected off the shutter blinds and received by the receiving unit. When the shutter blinds are open, the projected signal is reflected from the reflecting unit and received by the receiving unit. The output of the receiving unit is different, depending on whether the projected signal was reflected off the shutter blinds or off the reflecting unit. By analyzing the receiving unit output, the state of the shutter can be determined.

摘要： A camera which can detect the actual opening/closing state of the camera shutter based on a signal reflected towards the shutter by a signal projection unit and received by a signal receiving unit. The signal received by the signal receiving unit is based on the reflectivity of the shutter and, therefore, the signal received by the signal receiving unit is different depending on whether or not the shutter is open or closed. The camera has a reflectivity state detection unit for determining the reflectivity status of the shutter. A reflectivity standard changing unit changes the detection standard of the signal receiving unit based on information output by the reflectivity state detection unit. In this manner, changes in reflectivity of the shutter, due to passage of time or increase in use, will not reduce the accuracy of the detection of the open/close status of the shutter.

摘要： A camera including a shutter that regulates the exposure time of the recording medium, a shutter measuring device that measures the time during which the shutter exposes the recording medium, a discerning device that discerns whether or not the recording medium is an infrared sensitive medium, and a suppressing device that suppresses the action of the shutter measuring device when the discerning device discerns that the medium is the infrared sensitive medium. This structure prevents the accidental sensitization of infrared film in the camera. In an alternative arrangement, a controller controls the operation of the shutter measuring device in accordance with either the type of recording medium or a voltage amount supplied to the shutter measuring device.

摘要： A shutter operation detection device comprising a light emitting diode and a photo transistor is provided in proximity to the shutter curtains to measure the actual exposure time. The difference between the control exposure time, which is based upon the brightness value of the subject to be photographed and the film sensitivity, and the actual exposure time is determined. The control exposure time for the next session is corrected based upon this difference. The amount of correction for increasing the control exposure time is differentiated from the amount correction for decreasing the control exposure time.
