Title: Stopper device for copying machine or the like
Inventor: KITAZAWA MASAHIRO
IPC: G02B27/00
Filed: 1982-03-15
Abstract: PURPOSE:To enable safe operation without any protecting members in a copying machine wherein an original plate moves by determining the position for starting scanning with a stopper member when it is detained with a stopper rod in a body and stopping the original plate by bringing an elastic control piece into contact with a braking rod when the scanning ends. CONSTITUTION:When an original plate 2 arrives at the position for starting scanning, one actuator 3b of a stopper member 3 is detained by a stopper rod 4 provided to a body, whereby the plate 2 is positioned. In the position where the scanning of the plate 2 ends, an elastic braking piece 3c contacts with a braking rod 6, and the inertia of the plate 2 is absorbed by the friction with the rod 6; therefore, the plate 2 can be stopped slowly without generating vibration or the like in the plate 2 and the body 1 of a copying machine. To clean the optical system 7 in the body 1, the operator opens a front cover, then the stopper rod 4 is moved by the effect of a compression spring 5 to release the detention of the actuator 3b, thus the operator is able to clean the system 7 safely.

Abstract: PURPOSE:To improve the balance among density levels of respective component color images varying a developing bias voltage value for each developing device according to the degree of a decrease in the potential contrast at the developing device position so tha the development density level of a latent image by the developing device becomes constant. CONSTITUTION:A controller controls a high-voltage transformer HVT so that a predetermined proper bias voltage developing bias value is outputted to a selected developing device.

Title: Surface emitting type semiconductor laser
Inventor: NODA SUSUMU
IPC: H01S5/00
Filed: 1987-02-23
Abstract: PURPOSE:To obtain a surface emitting type laser whose structure is simple, whose threshold current is low and whose beam width is narrow by installing the following two: a light-guide layer provided with an even-order diffraction grating; a contact layer which is formed at a part of a region in the vertical direction with reference to the edge face of a resonator. CONSTITUTION:The following are formed on a substrate 1: a buffer layer 2; a lower clad layer 3; a multiple quantum well active layer 4; a barrier layer 5; a light-guide layer 6 provided with a second-order diffraction grating; an upper clad layer 7; a contact layer 8; an insulating film 9; electrodes 10a, 10b. The contact layer 8 and upper electrode 10a are formed only near the edge faces. Because the active layer 4 and the light-guide layer 6 constitute a distributed feedback laser resonator in an electric-current injection region 11, the length of the resonator can be sufficiently long corresponding to the length of the contact layer 8 and a threshold electric current can be lowered. Because the active layer 4 functions as a waveguide path and the diffraction grating functions as a diffraction-grating coupling light-radiating part in an electric- current non-injection region 12, a laser beam can be taken out in the plane direction Ps.

Abstract: PURPOSE:To eliminate wasteful time and to shorten the time required for image formation by normally rotating a rotary drum for the effective part of the image to be formed and rotating the rotary drum at a high speed in other cases. CONSTITUTION:An original scanning unit 14 is advanced by an optical step motor 20 subjected to driving control so as to move at the normal speed by as much as the length (length of sheet paper) instructed from a control part.
