摘要： PURPOSE:To obtain an easy and accurate transilluminating device with simple constitution, by using a fluorescent lamp to adjust the focus and determine the exposure and obtaining a proper quantity of the exposure light for strobe photography. CONSTITUTION:Such aperture value of a photographic lens is determined that the quantity of exposure light on the image plane is proper for a desired film sensitivity in accordance with the length from a strobe light emitting tube 11 to an object on a transparent set plate 6, the guide number of the strobe, etc. When this aperture value is set, a required shutter speed for the proper quantity of exposure light is obtained by the TTL photometry. Next, when fluorescent lamps 9 and 10 are lit and a camera 1 is focused to the object by the irradiated light through a light diffusing plate 7, the proper shutter speed due to the TTL photometry is different from a required shutter speed in accordance with the F value, the magnification, etc. When the aperture value is so adjusted that these shutter speed coincides with each other, fluorescent lamps are extinguished to obtain a proper quantity of exposure light due to lighting of the light emitting tube 11, and thus, an easy and accurate transilluminating device with simple constitution is obtained where the TTL photometric device is used.

摘要： PURPOSE:To prevent generation of warp and strain due to heat by arranging a refractory plate on a carriage and by providing a magnetic plate below the refractory plate so that papers may be attracted to the magnetic plate. CONSTITUTION:A substrate 10 of a carriage is made of a plywood or a synthetic resin plate, to which a magnetic plate 12 of iron or the like is adhered. A refractory plate 14 is mounted thereon into a laminated constuction so that the carriage may be prevented from being warped by the heat coming from an illuminating light source and so that papers may be magnetically attracted to the carriage. As another method for preventing the warp of the carraige due to the heat, the refractory plate 14 and the magnetic plate 12 are adhered into a plate, while being biased in advance to warp in the opposite direction to that of the warp due to the heat, so that the warping stress due to the heat may be offset.

摘要： PURPOSE:To make the device small-sized and facilitate operations improve the capacity, by arranging a condenser lens, a focusing lens, and an instant developing film in one line on the optical axis of the photographic lens in the rear of a film aperture. CONSTITUTION:The device is attached to the rear of a film aperture 11 of a single-lens reflex camera 10 to transfer the object image, which is focused by a photographic lens, to an instant developing film 21. In this case, a condenser lens 22, a focusing lens 23, and the film 21 are arranged in order in one line on the optical axis of the photographic lens in the rear of the aperture 11, and the object image focused by the photographic lens is focused on the surface of the film 21 through lenses 22 and 23. When the focal length of the lens 23 and the distance from the front focus position to the entrance pupil are denoted as fA and (t) respectively, t>1.5fA is satisfied.

摘要： PURPOSE:To make sharp imprinting of data possible despite the change in a background color by controlling exposure for imprinting according to the difference between the wavelength of the set background color and the wavelength of a light source for data imprinting. CONSTITUTION:When a dial for setting a background color is operated, the resistance values of variable resistors R1, R2 change according to the kinds of films and the background colors, and the charging time constant of a capacitor C changes. Then the charging voltage of the capacitor C attains a prescribed value and the time since a light source circuit 13 for data imprinting is lighted until said circuit is shut off is controlled with a control circuit 14 for extinguishing. As the difference between the wavelength of the set background color and the wavelength of the light source for imprinting is smaller, the exposure time is longer. Thus data is imprinted always sharply even when the background color changes.

摘要： PURPOSE:To facilitate the adjustment of an optical axis or swing by firmly fixing a camera and the like at a shiftable member mount unit via securing means and fixing member capable of adjusting an inclination angle. CONSTITUTION:Plate spring 12 and fixing member 14 are disposed between shiftable member 6 mount 6a and mount cover 10, and the fixing member 14 is fixed with the pressure of spring force of the plate spring 12 to the mount 6a. Screw 16 is screwed into the screw 18 and the screw 16 passes through holes 6b, 14a. The tip end of the screw 18 is pressed to the fixing member 14. Camera 8 or lamp house unit of enlarger is screwed into the tip end screw 16a of the screw 16, and it is secured to the mount 6a via the fixing member 14. Swing of the optical axis of camera 8 lens and the optical axis of enlarger lens can be adjusted by inclining the fixing member 14 with the adjustment of the amount of screwing of screws 22a, 22c, etc. screwed into screw holes 20a, 20c.

摘要： PURPOSE:To make correct photography possible by giving warning through a correcting circuit if a corrected shutter second value or the like exceeds limit seconds of a camera. CONSTITUTION:In case of the multiple mode, correction quantity information 0.25 is set to counters CNT1 and CNT2 if the first photographing is performed with a 0.25-fold exposure of a correct exposure. Therefore, exposure is performed in a quarter of the normal photographic seconds by a voltage VRF when shutter seconds are controlled. Next, if a 0.25-fold exposure of the normal exposure is set to perform the second photographing, push-buttons 7 and 8 are depressed in prescribed manners to set a 1/2-fold reference voltage of the reference voltage for normal photographing. Therefore, photographing is performed with a 0.5-fold exposure of the normal exposure. After this second photographing is terminated, total correction quantity 0.75 is displayed. When the last correction quantity setting exceeds 0.25, warning is given. Thus, correct photographing is always performed.
