The device is provided with imprinting exposure control means operating in such a manner that when the picture exposure correction factor setting means is operated in a direction to increase the exposure, the data exposure determined based on the film sensitivity setting means is caused to increase.

Abstract: A camera including a detector for detecting set information in an information supplying apparatus, and a controller for performing a particular camera operation on the basis of the result of the detection by the detection means. The particular camera operation includes at least exposure control and the control of the movement of a recording medium.

Abstract: A camera having a shutter device including leading and trailing curtains includes a first switch arranged to detect the ready-to-travel state and the travel-completed state of the leading curtain, a second switch arranged to detect the ready-to-travel state and the travel-completed state of the trailing curtain, and a decision circuit arranged to determine that the shutter device is abnormal, either when the ready-to-travel state of the leading curtain is not detected by the first switch or when that of the trailing curtain is not detected by the second switch, before an operation of the shutter device. The decision circuit also determines that the shutter device is abnormal, after completion of control over the travels of the leading and trailing curtains by the shutter device, if the travel-completed state of the leading curtain is not detected by the first switch within a predetermined period of time after the travel-completed state of the trailing curtain is detected by the second switch.

Abstract: A camera of the kind performing a preliminary flashing action before flash photographing for the purpose of preventing the red-eye phenomenon is arranged to give indications to enable the photographer to know selection of a preliminary flashing mode when this mode is selected and execution of the preliminary flashing action when the preliminary flashing action becomes feasible.

Abstract: A camera capable of communicating with an information reading and transmitting apparatus comprises a detector for detecting a signal output from the information reading and transmitting apparatus. A memory prestoring therein a plurality of programs for effecting a plurality of camera operations, a selector for selecting a particular program from among the plurality of programs on the basis of the result detected by the detector and a controller for controlling the camera operations on the basis of the particular program selected by the selector.

Abstract: A data imprinting device of the type in which data are imprinted on the film surface during the time when the film is transported. The device includes a data exposure device positioned on the presser plate which presses the film against the film gate of the camera in fixedly secured relation at a location corresponding to the vicinity of the path of movement of the film and a prohibitor responsive to accidental interruption of the film transportation for prohibiting further imprinting of data until the next frame, which came across the data exposure making device at the time of the accidental interruption, is brought into alignment with the data exposure making means as the film transportaion has been re-started.

Abstract: A camera has detection means for detecting a signal representative of set information from an information supplying apparatus, first control means for performing a particular camera operation on the basis of the result of the detection by the detection means, and second control means for performing a preset initial camera operation when the detection by the detection means has never been effected.

Abstract: A timer-assisted photographing mode control device for use in a camera of the type which has a timer circuit capable of delivering, at a predetermined time interval, signals relating to starting of a shutter releasing operation. When timer-assisted photographing operation is to be executed, a photographing mode suitable for the timer-assisted exposure is forcibly selected.

Abstract: In a liquid crystal driving system for driving a plurality of liquid crystal display devices with a single liquid crystal driver, segment signals from the driver are connected in common to the liquid crystal devices. Meanwhile, common signals which are connected to the liquid crystal display devices are in different waveforms from each other.

Abstract: In a data recorder for a camera having a data storing memory and control device for causing data to be recorded frame by frame for every photographed frame in the memory, film presence or absence discriminating device is arranged to inhibit data from being recorded in the data storing memory when the absence of the film is detected from a film detection signal received.

Abstract: This invention relates to an interval shooting device for producing release signals in a constant period to recycle the release operation with the constant period. When the winding of film does not really complete within a prescribed time required from the termination of the exposure to the completion of film winding, the subsequent shooting control by the interval shooting device is prohibited.

Abstract: A photographic camera is equipped with data recording means which is controlled to record data onto a film after a picture taking operation is completed following release of a trigger on the camera.

Abstract: A data recording control device for a camera in which a signal representing initiation of data exposure and another signal representing termination of the data exposure are given to one and the same channel so that an automatic film winding device does not start to operate at a time during the operation of the data recorder.

Abstract: The present invention relates to an interval timer device for a camera, particularly an interval timer for producing a release signal for operating the shutter release operation of a camera at a certain predetermined frequency and a charge signal for performing the charge operation of the flash device a certain predetermined time before the release signal is produced. In the case of this kind of the interval timer device, because the flash device has been charged a certain predetermined time before the release signal is produced, the flash time can be emitted without fail at the time of photographing. However, because the above device is charged independently of the object brightness, even in case the object brightness is so high that the flash photography is not necessary, unnecessary power is often consumed. In accordance with the present invention, the interval timer device produces the above charge signal only in case of a low object brightness, so as to eliminate the above shortcomings.

Abstract: A focus adjusting device is a type of an autofocusing device having a servomechanism which drives the lens of a camera to bring it into focus. The focus adjusting device is provided with an annunciator for informing an operator of the state of focus of the camera lens. The annunciator is actuated after confirming the finish of the distance measuring operation of the device and the stop of the lens in the focused position.
