IPC: G03G21/00
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To surely prevent developer from entering from an aperture part by providing the part of a cap member in contact with a photoreceptor with an elastic body and a power supply mechanism impressing a prescribed voltage on the surface of the elastic body. SOLUTION: The feeding/taking-up mechanism of a photoreceptor film 7 is incorporated in a drum pipe stock 6 and the film 7 is wound around the surface of the pipe stock 6 through the aperture part W formed on the pipe stock 6. Besides, the pipe stock 6 is provided with the power supply mechanism 8 with respect to the cap member 1. When the cap member 1 is attached to a prescribed position of the pipe stock 6, an elastic body for sealing is pressed to the film 7 on the aperture part W and brought into close contact with the film 7 while being bent. Then, the aperture part W is sealed so that carrier or toner does not enter the inside of the photoreceptor. Besides, when a printing action is executed, an almost identical voltage to the surface potential of the film 7 is impressed on the cap member 1 through the power supply mechanism 8 so that the carrier or the toner is not stuck.

Inventor: MONZEN TADAAKI
IPC: B21B37/00
Filed: 1992-10-30
Abstract: PURPOSE:To realize camber corrective operation by allowing accurate detection of camber amount which can not be detected conventionally because of snaking of steel plate at the time of rolling. CONSTITUTION:A steel plate 1 rolled through a mill 2 is fed to a downstream position thereof where the edge parts on the opposite sides of the steel plate 1 is imaged by means of two sets of two-dimensional cameras 3 disposed oppositely to the side edge parts and image signals are fed to an image processor 5. Upon receiving a steel plate detection signal 6 which turns ON when the steel plate 1 rides on a carry roll within the view of the camera 3, the image processor 5 begins to take image signals into an image memory. Edge lines of the images are linked by subjecting the overlapped part of serial images to linear proximation and aligning both lines thus determining overall edge shapes on the opposite sides of the steel plate. Finally, edge shapes on the opposite sides are added and divided by two to determine central position of the steel plate thus determining the amount of lateral curvature, i.e., camber amount.
