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.

摘要： Range measuring device for a camera measures the distances to objects respectively present in a central area of the photographing field and in plural areas including those surrounding the central area, then produces an outdoor signal indicating that the photographing is conducted outdoors or an indoor signal indicating that the photographing is conducted indoors, discriminates whether the object in the central area is the main object to be focused from the measured distance of the central area, and, if the distance in the central area is included in a reference distance range, determines the photographing distance based at least on the measured distance of the central area. The reference distance range is selected to be larger when the outdoor signal is produced than the case when the indoor signal is produced.

摘要： A buffer comprises a specially designed bearing for supporting the rotation axis of a rotatable mirror. The bearing structure is so designed that when the rotation of the mirror is stopped by a stopper, the bearing can shift the rotation axis in the direction in which force is applied to the rotation axis. This shift takes place at the moment of mirror stop. Immediately after the shift, the rotation axis is returned to its original position by a biasing force.
