Title: Optical ic package
Inventor: HANAOKA YASUO
IPC: H04B10/11
Filed: 1991-03-12
Abstract: PURPOSE:To obtain the compact optical IC package with high condensing efficiency and satisfactory frequency characteristics by providing a reflection mirror on the counter side of a lens part at the package. CONSTITUTION:The face of the side opposite to a lens part 4 at a package 3 is spherically formed with a photodetector provided in an optical IC 1 and constitutes a reflection mirror 11. A lead frame 2 is equipped with a through hole 12 at a part faced to the photodetector. Namely, parallel beams made incident from the front face of the package 3 excepting for the lens part 4 are reflected by the reflection mirror 11 and condensed through the through hole 12 to the photodetector of the optical IC 1. Therefore, the beams condensed from the front face to the lens part 4 and the beams reflected from the rear face to the reflection mirror are made incident on the photodetector, the condensing efficiency is improved. Further, since the number of the photodetector in the optical IC 1 can be suppressed to one, the frequency characteristics is improved.

IPC: G03G15/16
Filed: 1993-03-08
Abstract: PURPOSE:To perform en excellent transfer regardless of the thickness of a recording sheet by varying the ratio of the moving speed of the surface of an image carrier to that of the surface of a transfer device. CONSTITUTION:The image carrier 1 is rotated while being brought into contact with a transfer roller 2 and their drive sources are separately driven by the image carrier driving motor 3 of a variable speed and the transfer roller driving motor 4 of a uniform speed, respectively. Moreover, a cardboard mode changeover switch in a control part 7 is usually turned off. At this time, the image carrier 1 and the transfer roller 2 are driven so as to make the circumferential speeds uniform, respectively. Therefore, a recording sheet is usually a thin paper and the blurring of an image and a void in a transfer are not generated. When a user makes a copy on the cardboard such as a postcard, etc., the cardboard mode changeover switch is turned on. In the cardboard mode, the image carrier driving motor 3 is controlled so that the surfaces of the image carrier 1 and the transfer roller 2 has a difference in speed at the time of making the copy. Thus, the void in the transfer on the cardboard can be prevented.
