IPC: G03G13/00
Filed: 1987-04-21
Abstract: PURPOSE:To obtain a copy image having a stereoscopic sense by superposing arbitrarily an original and a light transmissive sheet on which an original image has been formed by a white or hypochromic toner, and furthermore, executing the copying. CONSTITUTION:A first original 1 is placed on an original placing table, a light transmissive sheet is used as transfer paper, and an electrophotographic process is executed, by which a white toner image corresponding to the first original 1 is formed on the light transmissive sheet 2. Subsequently, a second original 3 is formed by this light transmissive sheet 2 and the first original 1. When from on the first original 1, the light transmissive sheet 2 on which its original image has been formed by a white toner is shifted a little and superposed, an image of the first original is seen like a shadow of a white toner image. This second original 3 is placed on the original placing table so that the light transmissive sheet becomes an optical system direction, and the image copying is executed. In such a way, it is seen like a stereoscopic object on which only the shadow 4 has been formed.

Filed: 1988-04-22
Abstract: PURPOSE:To realize a small-sized and light-weight device, by organically arranging, in a package, a semiconductor laser element, a photo detector, an oblique glass plate to correct astigmatic difference and a detecting chip. CONSTITUTION:Laser light 8 radiated from a semiconductor laser element 6 is subjected to astigmatic difference correction by an oblique glass plate 13. Backward light 19 reflected by an optical disk surface is reflected by the oblique glass plate 13, and reaches a detecting chip 17 (a photo detecting device divided into four units, and photo detecting devices on both sides thereof). The focal deviation is detected by the photo detector device divided into four units, and the tracking deviation is detected by the two photo detecting devices. The light intensity of the laser light 18 is monitored by a photo detector 9. These components are integrated in a package. As the result, the optical path length of an optical system is shortened, the device is made small and light, and the high speed access of an optical pick-up is enabled.

A reference block size generating means 119 provides an output of a reference block size indicating a similar size to the block to be discriminated as an initial value. Furthermore, when a reference block size criterion outputted from the means 116 is not proper, a reference block size larger than the current size is outputted.
