Title: Image forming optical system
Inventor: KURODA MUNEO
IPC: G03B27/50
Filed: 1987-02-17
Abstract: PURPOSE:To resolve the reduction of resolving power by arranging anamorphic lenses in the front group and the rear group of a lens array so that axes of high refracting power of these lenses coincide with the slit breadthwise direction. CONSTITUTION:Anamorphic lenses 11 and 12 are arranged on the front side and the rear side of a lens array 10 which is provided between an original surface 1 and a photosensitive drum 2 and has plural converging light transmission unit bodies juxtaposed. Anamorphic lenses 11 and 12 are different in refracting power between the longitudinal axis and the transverse axis. Consequently, if their axes of high refracting power are equalized to the slit breadthwise direction, dimensions in the slit breadthwise direction (scan direction) of respective image areas of the original surface 1 and an image surface are reduced by the increment of the spread angle of the luminous flux from the original surface 1, and the image forming width is narrowed without changing the quantity of image forming light. Thus, the reduction of the resolving power due to the variance of the scan speed of the image is resolved.

According to this method, a soldering can be carried out in a very short time without conducting to the chip 1 while the current value of current to be conducted to the conductor 2 is adjusted and no bad influence affects the chip 1. When chips are soldered on both faces of the metal conductor, a carbon electrode is provided in the vicinity of a part on one side of the metal conductor, where it is subject to soldering. When chips are soldered on both faces of the metal conductor in a sandwich type, one side only of the metal conductor is conducted and heated, the heat is transmitted to the other side through the chip on the one side. By this way, it is also possible for chips to be joined on both faces of a metal conductor.
