Title: Laser scanning type optical device and image forming device
Inventor: HAMADA TAKATOSHI
IPC: H04N1/12
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce a maintenance cost by prolonging the product life of a semiconductor laser array which emits multibeams by selecting a laser beam source which emits a reference beam for determining the scanning recording position of image data on the basis of the load of the respective laser beam sources. SOLUTION: The laser beam source which emits the reference beam for determining the scanning recording position of the image data is selected on the basis of the load of the respective laser beam sources. A control circuit 41 executes the setting of the reference beam as a preprocessing for copying execution at the timing at which the power source of a copying machine is turned on. In such a case, the total light emission time information 481 existing in a RAM 48 is first referenced and a difference between the max. value and the min. value is determined. The difference is compared with the threshold stored in the RAM 48. If the difference exceeds the threshold, the reference beam ID stored in reference beam information 482 is changed to the ID of the beam of the min. total light emission time.  The ID of the reference beam after the change is announced to an LD drive control section 42.

Abstract: PURPOSE:To make it possible to use coils without generating any dust even under a strict condition imposed, such as high temperature and clean environment by carrying out large current power supply processing or heating processing under vacuum until the temperature of molded coils exceeds the highest temperature available for practical application. CONSTITUTION:A coil 11 is placed into a vacuum vessel 15 and connected with a power source 14 y way of conductors 12 and 13.
