Title: Recording sheet guide
Inventor: YAMAMOTO SUSUMU
IPC: B41J13/10
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce vibration associated with printing without releasing an urging force toward the circumferential side of a recording sheet and obtain a high quality print image by providing a structure which makes a part engaging with the recording sheet non-parallel to the terminal end of the recording sheet at the time of printing. SOLUTION: A sheet guide member 4a made of a sheet is made by cutting off diagonally a part engaging with a recording sheet wrapped around the circumferential surface of a platen roller 5, non-parallel to the terminal end of the recording sheet. And then, at the time of printing, the terminal end of the recording sheet which turns together with the platen roller 5 passes through the part of the sheet guide member 4a (base end) that engages with the recording sheet. On that occasion, an urging force generating in a structure such as a paper carriage is released not instantly rather gradually, reducing vibration given to the recording sheet. Thus high quality print image can be printed by preventing a printed state such as a stripe due to the vibration of the recording sheet.

Filed: 1979-04-06
Abstract: PURPOSE: To obtain the illuminance distribution for correcting peripheral beam attenuation irrespective of scanning positions by disposing a shield plate which shields part of lighting light between a cylindrical quadratic reflecting mirror and plane reflecting mirror and moving the shield  plate in synchronization with the oscillation of the plane reflecting mirror.   
     CONSTITUTION: A shield plate S is provided between the plane reflecting mirror M and cylindrical elliptial reflecting mirror R and is supported movably forward and backward in the direction  of crossing the luminous flux from the cylindrical elliptical reflecting mirror R. The shield plate S  is a slender plate having a longitudinal rectilinear edge 4 and a convex arc edge 5 opposing to this  and is so formed that the luminous flux of the central part in the slit direction is shaded more than  the luminous flux at the end part by the convex arc edge 5. The shield plate Sa is connected to  the oscillation shaft of the plane reflecting mirror Ma by a power transmission mechanism. While  the lighting system A is lighting the side edge E 1 , the shield plate does not shade the luminous flux  and as it scans toward the other side edge E 2 , the shield area is increased. This operation is similar with the lighting system B as well. In this way, the illuminance distribution having no unevenness irrespective of the scanning positions is obtainable.

Abstract: PURPOSE:To efficiently generate film forming particles and to form a thin film while setting an optional film forming angle by irradiating the rugged surface of a target consisting of minute units with an ion beam and sputtering the target. CONSTITUTION:The target 13 is irradiated with an ion beam 12 from an ion beam source provided with a cylinder 10 for nitrogen, argon, etc., and an ion source 11, the target is sputtered, and the sputtered particles 14 are deposited on a substrate 15 opposed to the target to form a film. In this ion sputtering method, the surface of the target 13 to be irradiated with the ion beam 12 is a rugged surface consisting of minute units. In addition, the sectional shape of the rugged surface consists of minute unit surfaces at an optional angle to the irradiation ion beam 12. As a result, the rugged surface is irradiated at a sufficiently large angle and the whole target 13 is irradiated at a small apparent angle with the ion beam, respectively, and hence the distance between the target 13 and the substrate 15 can be reduced. By this method, an optional film forming angle can be set, and sputtering efficiency is improved.
