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： There is disclosed an analog-to-digital converter for a camera which is arranged to convert an analog signal of an exposure information, particularly a photometric output of a light measuring circuit into a corresponding digital signal. The analog-to-digital converter according to the present invention includes means for dividing a photometric output signal of a light measuring circuit, which is fed into an analog-to-digital converting circuit, into predetermined areas, means for level-shifting the respective ones of the divided areas of said photometric output signal, and means for feeding the level-shifted photometric output in the respective areas, separately, into the analog-to-digital converter circuit, whereby digital values are obtained, separately, in connection with the respective ones of the divided areas of the photometric output signal.

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： 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： The present invention relates to the exposure compensation information forming apparatus for a camera, particularly for forming the aperture and the totally opened aperture value information. Until now in order to compensate the totally opened aperture value contained in the output of the light measuring circuit and the aperture value the information setting means for the totally opened aperture value and that for the aperture value are provided, whereby both setting means are mechanically engaged with each other so as to form the totally opened aperture and the aperture information. Thus, the engaging mechanism of both of the above means is complicated, which is inconvenient. The present invention provides an exposure compensation information forming apparatus by means of which the aperture information can be composed from the totally opened aperture with a very simple circuit composition so as to overcome the above disadvantage.
