Inventor: TAKADA YOSHINAO
IPC: G03B27/62
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of an error in the selection of recording paper size at the time of using a copying machine. SOLUTION: An original setting surface S is formed on an original platen G of an image reader in a copying machine by the use of a glass plate or the like and the upper left corner of the surface S is set up as an original setting reference position P. Lighting display means M, N are formed on two horizontal and vertical side parts X, Y holding the position P between them. When selected recording paper is size A4 e.g. only display means corresponding to the size A4 out of the means M, N consisting of LEDs or the like are turned on. Thereby a user can visually grasp size relation between an original and recording paper only by setting up the original on the surface S without requiring the check of display contents or the like on an operation panel.  Since whether the selection of recording paper size is proper or not can be quickly discriminated prior to the execution of copying, the generation of copying in recording paper of incorrect size can be prevented.

IPC: H05B33/14
Filed: 1989-12-07
Abstract: PURPOSE:To obtain a high luminance thin film EL element which is chemically stable, without giving bad effect to an emission layer mother material by forming the emission layer out of sulfide of group IIIA elements. CONSTITUTION:An emission layer is formed out of sulfide of group IIIA element, while a rare earth element is added thereto as the center of emission. Namely, by using plurality of deposition sources arranged in a vacuum container, a group IIIA element and sulfur are controlled and evaporated respectively, and are chemically bonded together, so as to form a film. By using sulfide of group IIIA element for an emission layer material, and by adding a rare earth element thereto for the center of emission, the combination of similar ion radius is achieved, while little defection is generated, and concentration extinction is hard to produce. Since the good quality thin film can be obtained with a stoichimetry maintained, a high luminance EL device can be obtained, and the thin film EL device in such a structure is chemically stable.
