Title: Document reader
Inventor: HASE KANAME
IPC: H04N1/19
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To reduce the necessary space small and make the device compact by scanning a document by a reflecting means such as a mirror and projecting an image of the document on a photoelectric converting means. SOLUTION: When a cam 6 rotates at a constant speed, a mirror 7 rotates through a link 5 and the reflection angle varies, so that the read position of the document moves in a vertical scanning direction. Each time the document is scanned by a certain distance, a linear CCD converts input light into an electric signal and outputs it in synchronism with the rotation of the cam 6. The document is read more as the cam 6 rotates and when the read position reaches the end of the document, the read ends; and a driving part reverses to set the cam 6, a lens unit 3, and the mirror 7 at their initial positions, and the scanning is completed. In this case, the lens unit 3 is moved reciprocally along the optical axis of the lens 2 associatively with the angle of the mirror 7 and a link 4 is formed between the cam 6 and lens unit 3 so that the read optical path length becomes constant.  Consequently, the need for a complex mechanism for the movement is eliminated and the read is made fast.

Abstract: PURPOSE:To prevent damages by the casting of leaked light of YAG laser light on a guiding-light oscillator by providing a parallel flat plate, which is highly reflective against the YAG laser light and has high transmittance for the guiding light between a YAG laser oscillator and the guiding-light oscillator. CONSTITUTION:As a laser 1 for guiding light, which oscillates the guiding light, a helium or neon laser or a visible semiconductor laser is used. A YAG laser oscillator 3 is highly reflective against YAG laser light. A coated parallel flat plate 2 constituted of a dielectric multilayered film having the high transmittance for the guiding light is inserted on the same optical axis of the YAG laser 1. The leaked YAG laser light from a front reflecting mirror 6 is reflected from the parallel flat plate 2. The light reaching the guiding-light laser 1 becomes minimum. Meanwhile, the guiding light reaches the YAG laser oscillator 3 with almost no attenuation. Therefore, the leaked light of the YAG laser light does not give damages on the guiding light oscillator.
