Title: Paper feeding and carrying roll
Inventor: WATABE EIKO
IPC: B65H3/06
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To keep a stable frictional coefficient with being hardly influenced by paper powder, and keep stable paper feeding and carrying characteristic by regulating the surface potential of a paper feeding and carrying roll in paper passing within a prescribed range. SOLUTION: In this paper feeding and carrying roll used for feeding or carrying of paper sheets, the surface potential in paper passing is regulated to 0kV∼-20kV. The regulation of the surface potential is performed by properly selecting the roll material, the kind of a filler, and the surface treatment of the roll. When this paper feeding and carrying roll is used, the paper surface is positively charged, the roll surface is negatively charged, and the surface potential of the roll surface becomes 0kV∼-20kV. On the contrary, when a general rubber roller is used, the surface potential is about -50kV∼-70kV. Since paper powder is charged with positive charge, on the other hand, the paper powder is extremely hardly adhered to this paper feeding and carrying roll, compared with a conventional roll.  Thus, the reduction in frictional coefficient by adhesion of paper powder can be prevented.

Title: Device for heat development
Inventor: ISOZAKI EIICHI
IPC: B65H27/00
Filed: 1992-12-04
Abstract: PURPOSE:To provide a heat developing device in which adhesion property between a heat developable photosensitive material and a heat roller is maintained during heat development and irregular development or scratches on a picture surface can be prevented. CONSTITUTION:A guide plate 44 of a heat roller 24 is energized to be in contact with the surface of the heat roller 24 by the elastic force of the plate 44 itself. Thereby, a photosensitive material 20 is passed while being pressed to the heat roller 24. Since the emulsion plane of the photosensitive material 20 directly touches the plate 44, such a plate material is suitable that is not hydrophilic, causes no sticking of the photosensitive material, and has proper rough surface but does not scratch the emulsion. For example, a glass fiber fabric coated with PTFE has a surface with periodic ruggedness with <=3mm pitch. Since this plate material is not hydrophilic, it is good enough as the guide plate for the photosensitive material 20, and further, the plate has fine ruggedness, it is preferable not to scratch of the emulsion.
