Title: Photosensitive material carrying method while processing photosensitive material
Inventor: MARUYAMA NORIHARU
IPC: G03D3/08
Filed: 1986-04-02
Abstract: PURPOSE:To clamp a photosensitive material from both faces, and to carry it by converting its direction, by bringing a processing fluid to countercurrently flow to a surface side having the emulsion surface of the photosensitive material, and supporting the surface having no emulsion layer of the photosensitive material by a supporting means which extends in the carrying direction. CONSTITUTION:When the photosensitive material is carried along turn parts 20a, 21a of supporting means 20, 21, the photosensitive material P goes straight on and ascends, therefore, its tip part abuts on the turn part 21a of the supporting means 21. As a result, in the photosensitive material P, the force for pushing vertically the slant face of the turn part 21a, and the force for bending the photosensitive material P along the slant face are generated, it operates as a resultant force onto the photosensitive material P, and received by the photosensitive material P being a flexible body. Accordingly, the photosensitive material P itself is meandered and apt to go soft, but from the inside, the countercurrent flow of a processing liquid presses the whole surface of the photosensitive material P in the direction of the turn part 21a of the supporting member 21, and the photosensitive material P is supported and carried by both of them, therefore, the photosensitive material P is supported and carried by both of them, therefore, the photosensitive material P is not buckled but the tip part is easily bent and carried. In this way, the direction in the inside of the processing liquid is converted without using a special driving force.
