Abstract:
An intermediate guide member is provided attachable and removable between a head portion and a supporting frame of a stocker for printing plates. A number of intermediate guide members is an element to set a time of starting downward movement of hooks supporting a leading end of a printing plate. Three conditions in accordance with lengths of non-detection times are set for detecting the printing plate to judge authenticity of the detection. When the hooks reach vicinities of stoppers provided at supporting bars of a reversal unit, the hooks swing, are pulled-in from above the slope, and transfer the printing plate to the stoppers. Thereafter, by rotating the supporting bars and the stoppers integrally around a shaft, the printing plate is pivoted over toward a back plate, and a lower end of the printing plate is transferred from the stoppers to a receiving plate without damaging the printing plate.
Abstract:
An improvement of microfilm camera with a marking device in which an image of a document is photographed on a roll film mounted in a cassette using a slit exposure system and a two-dimensional digital image of a mark is recorded on the roll film. The microfilm camera comprises: an image taking lens for forming the image of the document on the roll film; a mark taking lens having an optical axis inclined in the length side direction of the roll film with respect to that of the image taking lens; and a digital image generator for generating a one-dimensional digital image extending in the width side direction of the roll film and formed by said mark taking lens at or in close vicinity of the image forming position of the image taking lens. The two-dimensional image of the mark is recorded on the film by changing the one-dimensional digital image synchronously with traveling of the film. With such construction, the size of a photographic opening provided in the cassette can be reduced to made the cassette structure simple. It is unnecessary to provide a complicated synchronizing mechanism for setting mark projecting or recording timing.
Abstract:
There is provided a microfilm cassette capable of reducing the case size and obtaining a rational arrangement of elements such as reels and photographic roller. The microfilm cassette includes: a case having a substantially rectangular shape as viewed from the top; a supply reel and a take-up reel mounted inside the case and arranged adjacent to each other horizontally in the length side direction of the case; a photographic opening located around the center of one short side of the case; a photographic roller arranged in a position opposite to the photographic opening; and a shutter for opening and closing the photographic opening. The short side of the cassette case on which the photographic opening is located may be bulged and expanded outwardly around the center of the photographic opening, so that the mark taking lens and the image taking lens can be arranged close to each other. Further, a pair of labels may be attached to the case in positions substantially symmetric with respect to the central axis parallel to the long side of the case. The microfilm camera for this microfilm cassette is also provided.
Abstract:
A film processing device contains a film feed unit, a film developing unit, a film drying unit, and a film winding unit. The drying unit and the winding unit are integrally structured, and the feed unit, developing unit, and the drying/winding unit are independently arranged in the casing and are independently detachable. The film processing device can be further provided with an upper cover having processing rollers attached thereto, which is vertically movable with respect to the casing so that the rollers are dipped into the developing and washing liquids when the upper cover is lowered.

An intermediate guide member is provided attachable and removable between a head portion and a supporting frame of a stocker for printing plates. A number of intermediate guide members is an element to set a time of starting downward movement of hooks supporting a leading end of a printing plate. Three conditions in accordance with lengths of non-detection times are set for detecting the printing plate to judge authenticity of the detection. When the hooks reach vicinities of stoppers provided at supporting bars of a reversal unit, the hooks swing, are pulled-in from above the slope, and transfer the printing plate to the stoppers. Thereafter, by rotating the supporting bars and the stoppers integrally around a shaft, the printing plate is pivoted over toward a back plate, and a lower end of the printing plate is transferred from the stoppers to a receiving plate without damaging the printing plate.
