摘要： An electric current is supplied from a power source to a motor for transporting a film through a switching element (a transistor). A regenerate current is generated from the motor when the current supply is cut, and the regenerate current is returned to the motor through a switching element (a first MOS FET). The switching elements are turned on and off according to the state of a second MOS FET. When the second MOS FET is turned on, the transistor is turned on and the first MOS FET is turned off, and this drives the motor. When the second MOS FET is turned off, the transistor is turned off and the first MOS FET is turned on, and this stops the motor.

摘要： PROBLEM TO BE SOLVED: To perform photographing until attaining the prescribed number of exposed frames of photographic film even in the case of inadvertently performing the changeover operation of the position of a pressing plate by inhibiting the change of a tunnel gap for the photographic film in the case of performing photographing to the photographic film whose prescribed number of exposed frames is small after attaining the prescribed number of exposed frames. SOLUTION: When a changeover signal is inputted by the operation of a pressing plate position changeover switch 37, the present number of the exposed frames is read. When the number of the exposed frames is less than 16, a pressing plate position changeover permission signal is outputted, and a pressing plate position changeover motor 36 is rotated to change over the pressing plate position. When the number of the exposed frames is not less than 16, the present tunnel gap is detected by a tunnel gap detection switch 71. When the tunnel gap is for 220, a pressing plate position changeover inhibition signal is outputted and the motor 36 is not rotated, so that the pressing plate position is not changed over. When the tunnel gap is for 120, an all-frame feeding signal is outputted and the photographic film 16 is all taken up to a spool 17.

摘要： PROBLEM TO BE SOLVED: To automatically change the tunnel gaps between film rails and a pressure plate, in accordance with the kind of 120 size film. SOLUTION: Pushing pins 51 are provided outside the film rails and shifted in the optical axial direction of photographing by pushing cams 55. A pressure plate 42 is pushed by the top ends of the pushing pins 51 to be shifted in the optical axial direction of photographing. The rotation of a film feeding motor 35 is transmitted to a spool rotary shaft 18 through a film feeding gear train 61 to feed a film. A pressure plate position switching gear train 58 is linked with the film feeding gear train 61 through a planetary gear clutch 59. A bar code sensor is provided in the path of the film to read the kind of the film. The film feeding motor 35 is rotated in the direction opposite to the feeding direction of the film to change the tunnel gaps by the pushing cams 55 so that the tunnel gaps in accordance with the kind of the film can be obtained.

摘要： PROBLEM TO BE SOLVED: To smoothly wind up a film of Brownie size. SOLUTION: Guide holes 50 are formed outside film rails 40 and 41 and a pushing pin 51 is fitted to be freely slidable and shifted by a pushing cam 55. The tunnel gap between the film rails 40 and 41 and a film pressure plate 42 is switched for the 120 roll film and 220 roll film by the shifting of the pin 51. The tunnel gap is set for the 120 roll film regardlessly of the kind of film to feed the film and set the first frame in an aperture. The spliced part of the 220 roll film being thick because of composite thickness of three kinds of thickness of the film, a trailer paper and a splicing tape passes through the widened tunnel gap, so that the film is smoothly wound up around a spool.

摘要： PROBLEM TO BE SOLVED: To save power by turning off an image display means, when the fact that a photographer looks through an optical finder is detected, in a camera provided with the image display means. SOLUTION: A photodetection sensor consisting of a light emitting part 28a and a light receiving part 28b is provided in the vicinity of a finder eyepiece part 20, to detect the fact that the photographer looks through the optical finder or not, based on the quantity of light received by the light receiving part 28b. When it is judged that the photographer looks through the optical finder, based on the result of the detection, the supply of the power to a liquid crystal monitor 8 is stopped. Thus, futile power consumption can be suppressed and the power can be saved.

摘要： PURPOSE:To provide a photographing mode changeover inhibiting device capable of preventing the futile use of a film by preventing a panoramic photographic whose image is not excellent from being taken when an ISO value is extremely small or large. CONSTITUTION:When a panoramic switch 16 is turned on, photographing mode changeover processing is started (the step 101) and the ISO value of the film to be used is read by a CPU 10 (the step 102). It is judged whether the ISO value is smaller than ISO 100 or not (the step 103). When it is not smaller, it is judged that the ISO value is larger than ISO 400 or not (the step 104). When it is not larger, a photographing mode is switched to a panoramic photographing mode (the step 105) to return to a main routine (the step 106). When the ISO values is smaller than ISO 100 in the step 103 or larger than ISO 400 in the step 104, the mode is not switched to the panoramic photographing mode to return to the main routine (the step 106).
