    摘要： In the disclosed camera, a switchover arrangement automatically shifts from an automatic exposure mode to a flash mode in response to a charge completion signal from a flash device. A line electrically connects a terminal capable of receiving the charge completion signal from the flash unit to the switchover arrangement. A switch connected to the connecting line applies a signal of a value corresponding to the charge completion signal from a signal source in the camera to the switchover arrangement to cause the latter to effect a switchover to the flash mode in response thereto in the same manner as when a charge completion signal is applied thereto.

    摘要： A voltage detecting means is provided in a flash lamp firing circuit for detecting the attainment of the voltage of a storage capacitor to a satisfactory lamp firing voltage level to assure that a photographic camera associated with the flash lighting unit operates in a flash exposure range switched from a daylight exposure range only when a sufficient voltage is available to fire the lamp at the time of striking of the lamp. In one embodiment, the detecting means comprises two transistorized circuits having output terminals one of which is connected to the gate lead of a SCR in a discharge circuit of the lamp, and another output terminal which is arranged to be connectable to a light-emitting diode of the camera and therefrom connected to the gate lead of an electronic change-over switch for selection of the operating ranges of the camera, the light-emitting diode being arranged to be visible from the outside of the camera so that the operator is immediately aware if the storage capacitor voltage has attained the satisfactory firing level.

    摘要： In the disclosed device, a signal forming circuit produces a signal having a frequency corresponding to the voltage of a power source. A level detector detects the level of the voltage of the power source and is arranged to produce a signal when the voltage of the power source drops below a predetermined level. A control circuit coupled to the signal forming circuit is arranged to change the frequency of the signal produced by the signal forming circuit in response to the signal produced by the detector. An indicator operates at the frequency of the signal produced by the signal forming circuit. In a specific embodiment, a detector detects whether the voltage of a battery is at and below a first level, between the first level and a second higher level, and at and higher than the second level. A signal former responds to the detector for producing a first signal having a frequency below a first frequency when the voltage is below the second level, a second signal having a frequency twice the first frequency when the voltage is at the second level, and a signal having a frequency higher than the frequency of the second signal when the voltage is above the second level. An indicator responds to the signal former to operate at the frequency of the signal former.

    摘要： The present invention relates to a camera having a sound-making element provided at a suitable position thereof in which sound signals are used as warning signals or confirming signals for operation of a self-timer.Sound control of said sound-making element is done by using counting signals of a binary counter which digitally controls the camera.Sound signals as warning signals and those as confirming signals for operation of a self-timer are distinguished by a difference in oscillation pulses.

    摘要： A digital camera with five automatic exposure modes is provided with corresponding individual cards upon selective insertion into the camera to effect the operation of either or both of the shutter and diaphragm in accordance with the digital output of a computer through logic selection circuits as the mode information on the inserted card is read into a binary coded decimal counter controlling operation of the logic circuits. When the card is absent from the camera, a first controlling push button for sequential display of the modes is rendered effective to pass a pulse train to the counter so that upon release of the button, the current mode displayed can be set. The card further includes information relating to the determination of whether or not to give a sound warning signal which occurs, in one embodiment, when the film nears the terminal end of footage. In another embodiment, the buzzer is utilized to assist in releasing not only a first but also an additional three buttons for setting exposure factors and a number of film frames available just after a desired symbol or digital value appears in the display as they are sequentially presented.
