    摘要: An information setting device for a camera comprises a plurality of manual operation switches for setting varied kinds of information. Among these switches, when a plurality of switches are simultaneously operated, there obtains a specific setting mode for setting information of a kind different from information of other kinds to be set by individually operating these switches. In the event of thus selecting the specific setting mode, this mode remains unchanged even when at least one of the simultaneously operated switches becomes inoperative.

    摘要: Disclosed are a technique that in the film feeding control of a camera, before the film is wound up, when the voltage of a battery circuit for supplying voltage to the camera is above a voltage level high enough to wind-up the film, a film winding operation is initiated, and, if this winding-up operation does not terminate normally, that the film has ended is determined and the film is rewound, and another technique that when the above-described voltage level is detected, a motor for the rewinding is used as the load of detecting the voltage level of the above-described battery circuit.

    摘要: A multiple exposure device for a camera is arranged to permit one and the same frame portion of film to be exposed to light a plurality of times. In taking a multi-exposed photograph, the device displays a multi-exposure mode; permits a manual resetting operation on the multi-exposure mode for improved operability of the camera; and computes the degree of exposure to be effected at each step of the multiple exposure to ensure an appositely exposed state of the film frame on which the multiple exposure operation is performed.

    摘要: The present invention relates to a photographic information setting device having a switch arranged to turn on and off and generate digital data when a stepwise operating member changes its position, wherein the turning on and off of the switch is detected with the help of current supply to the switch to renew the digital data until a desired value of any exposure factor is preset. In the present invention, when the aforesaid stepwise operating member lies in any of click-stopped positions, the current supply to the switch is cut off to prevent wasteful consumption of electrical energy. The number of times of turning on and off of the switch is once stored in a counter, and, upon detection of turning on and off of the switch, a computer reads out the content of the counter so that the renewed digital data are formed in the interior of the computer.

    摘要: A film drive device for a camera in which the film is transported by an electric motor as the drive source, comprises detecting means for detecting that the winding of all the frames of the film is complete, manually operable switching means for forcibly changing over the film to a rewind state, and operation control means for shifting from a film windup state to the film rewind state. The operation control means makes a first operation of shifting to the film rewind state in response to the completion of the winding by the detecting means and a second operation of shifting to the film rewind state by the operation of the switching means different from each other. Therefore, an efficient shifting to the rewind state can be performed.
