摘要： PROBLEM TO BE SOLVED: To make a picture and characters easy-to-view by changing the background color and character color of a character display part in accordance with the brightness of the picture displayed on a liquid crystal display screen. SOLUTION: A liquid crystal display whose aspect ratio is 3:4 is used for the picture display liquid crystal monitor of a camera with a liquid crystal finder, and the picture (an aspect ratio is 9:16) equivalent to a silver salt picture is displayed on the liquid crystal display screen 80 of the liquid crystal monitor, and a remaining margin part (an area shown by oblique lines in a figure) is used as a character display area 82. Then, in the case that a display picture displayed on the picture display area 84 is bright, white characters are displayed by making the background of the character display area 82 black, and in the case that the display picture is dark, black characters are displayed by making the background of the character display area 82 white.

摘要： PROBLEM TO BE SOLVED: To attain space-saving by combining and arranging an improved battery with the other member at the inside of a take-up spool at a camera using the improved battery capable of being repeatedly discharged and charged. SOLUTION: As for the camera where a main battery 34 is charged by a charging circuit by having an auxiliary battery 40 such as an AA type battery or the like as a charging power source and power is supplied to the camera circuit of a film feeding motor 30 or the like from the main battery 34; the film feeding motor 30 and the main battery 34 are arranged up and down at the inside of the take-up spool 28. Then, a main battery housing case 35 surrounding the periphery of the main battery 34 is provided, so that the rotating take-up spool 28 is prevented from being brought into direct contact with the main battery 34, and also the positive electrode of the main battery 34 is made to directly abut on a printed circuit board 46, so that an armature member is eliminated. Also, the housing part of the main battery 34 is made to have a light-shielded structure by the main battery housing case 35, so that light is prevented from entering the inside of a spool chamber at the time of exchanging the main battery 34.

摘要： PROBLEM TO BE SOLVED: To use a battery for silver salt film photography and a battery for electronic still photography in common, to eliminate the need of a battery only used for electronic still photography and to make a camera small in size and light in weight by supplying power to a 2nd camera part from the electric circuit for light emission of a stroboscopic device. SOLUTION: The power is supplied to a digital still camera(DSC) power source part 186 from a stroboscopic circuit 180. A stroboscope is always repeatedly charged in terms of a control program so that it can emit light any time. Since the stroboscope scarcely emits light at the time of photographing, it is usually repeatedly charged wastefully. The power consumed for such wasteful charge and discharge is effectively utilized by the power source part 186 and the battery for the power source part 186 provided independently in the conventional manner is disused. Since voltage for stroboscopic light emission is usually near to 300 V, the voltage of about 300 V supplied to an input part is made to drop and supplied to a rectifying and smoothing part.

摘要： PROBLEM TO BE SOLVED: To realize the focusing of a 1st photographing optical system in a state where a substrate is attached to the rear of an aperture surface by arranging the substrate of an imaging device so as to keep away from a range where the light for focusing of a 1st photographing optical system passes. SOLUTION: The focusing of an APS photographing lens executed after the assembly of a composite camera is performed by arranging a light source in front of the APS photographing lens and arranging a collimator on an opposite side to the light source by putting the APS photographing lens in between. A pressing plate 115 is attached to the specified position of an aperture 112, and a through-hole 115A is formed in a range where the light for focusing from the light source passes on the plate 115. The substrate 126 is attached to a position where it is kept away from the range where the light for focusing passes. Therefore, the focusing of the APS photographing lens is executed in a state where the substrate 126 is attached to the rear of the aperture 112, and the substrate 126 need not be detached in the case of readjustment.

摘要： PROBLEM TO BE SOLVED: To finely adjust the viewing angle of an APS photographing optical system and a DSC photographing optical system and to reduce the number of motors by setting the viewing angle of either photographing optical system as reference and moving the variable power system lens of the other photographing optical system. SOLUTION: A driving mechanism is provided with a 1st gear mechanism 182 for transmitting the driving force of the motor 180 to the variable power system lens side of an APS photographing lens 12 and a 2nd gear mechanism 184 for transmitting the driving force of the motor 180 to the variable power system lens side of the DSC photographing lens. The gear 210 of the 2nd gear mechanism 184 is meshed with a gear 200 constituting the 1st gear mechanism 182, and the gear 216 is meshed with a rack 218 formed on the lower surface of the cam plate 156 of a CCD unit 120. Therefore, when the motor 180 is driven, the driving force is transmitted from the gear 200 to the cam plate 156 through the 2nd gear mechanism 184. Thus, the number of motors is made smaller than in a system where the respective variable power system lenses are driven by a dedicated motor.

摘要： PROBLEM TO BE SOLVED: To make easily correctable a parallax between a photographing range exposed at a photographic film and a picture displayed at the electronic finder of an LCD or the like by turning on/off a short distance correction mark for correcting parallax at the electronic finder of a liquid crystal monitor or the like. SOLUTION: This composite camera is independently provided with an APS photographing lens forming a subject image at the photographic film and a DSC photographing lens forming the subject image at the light receiving surface of an imaging device. When the picture is displayed at the liquid crystal monitor 40 based on an image signal obtained through the imaging device, the short distance correction mark 40A for correcting a parallax between the APS photographing lens and the DSC photographing lens is turned on at the monitor 40 in the case that a subject distance is shorter than a prescribed short distance. In the case that the subject distance is over the prescribed short distance, the mark 40A is turned off.

摘要： PROBLEM TO BE SOLVED: To miniaturize a composite camera consisting of an APS camera and an electronic still camera by arranging the mechanical machinery part of the APS camera on the first side of a camera main body, arranging the image processing circuit part of the electronic still camera on the back side of the mechanical machinery part and arranging a control substrate for generally controlling the composite camera at the upper parts of the mechanical machinery part and the image processing circuit part. SOLUTION: By arranging the mechanical machinery part 102 of the APS camera part on the front side of the camera main body and arranging the image processing circuit part 114 of the electronic still camera part on the back side of the machinery part 102, the space in the thickness direction of the camera main body is efficiently used. By arranging the control substrate 112 for generally controlling the composite camera 10 on the upper parts of the machinery part 103 and the circuit part 114, the space in the height direction of the camera main body 100 is efficiently used.

摘要： PROBLEM TO BE SOLVED: To provide a camera capable of arranging a magnetic head at an optional position and magnetically writing data from the top position of a magnetic recording area by obtaining a magnetic write starting value based on the position of the magnetic head. SOLUTION: A magnetic write starting position is obtained based on a distance between the top position of the magnetic recording area 11n and the magnetic head 40. After exposing a photographic frame 10n, the film 10 is wound and fed by a feeding motor 20, etc., and the feed amount of the film is detected by a rotary encoder 35 and a pulse counter 36. When the detected film feeding amount attains the film feeding amount in accordance with the magnetic write starting position, a microcomputer 22 designates a magnetic head driver 41 to start to write magnetic data by the magnetic head 40.
