Title: Focus control device
Inventor: MAEDA TAKANORI
IPC: G11B7/09
Filed: 1984-12-12
Abstract: PURPOSE:To execute with a high accuracy a focus control by an inexpensive and light constitution by forming an optical means by placing correspondingly many absorbing parts for absorbing a light by shifting the position, on both faces of a parallel face plate for making a light transmit through. CONSTITUTION:A luminous flux is made incident on a disk 15 through an objective lens 14, and its reflected light is led to a photodetector 17 through an optical means 16. The optical means 16 is formed by placing an absorbing part 16a which does not make a light transmit through by shifting the position, on both faces of a transmitting part 16b of a parallel face plate for making a light transmit through, and a line for connecting the end parts of a pair of absorbing parts 16a is inclined by a prescribed angle against the optical axis. When a disk 15 is focused, parallel rays are made incident on the optical means 16, and when they approach the lens 14, they become a diffused light, a transmitting light is made incident mostly on the right half 17b of the photodetector, and when it goes away from the lens, it becomes a converged light and made incidently mostly on the left half 17a. By detecting this difference by an amplifier 18, a focused state is detected, and the detection accuracy can be raised by an inexpensive and light structure.

IPC: G03G15/08
Filed: 1989-10-11
Abstract: PURPOSE:To prevent runaway in controlling the supply of toner by switching the supply of toner from a control toner supply to a quantitative toner supply when the detection signal of the density of the surface of a photosensitive body where a developed image is not formed increases to more than that of the previous time under a specified condition. CONSTITUTION:A selection means is actuated when a difference between the previous detected value VSGm and the present detected value VSGm+1 of the density of the surface of the photosensitive body where the developed image is not formed exceeds a previously set reference value DELTAVSG under the specified condition. By actuating the selection means, a control toner supply means for supplying a specified quantity of toner is switched to the quantitative toner supply that the fixed quantity of toner is supplied every time the image is formed based on the detection signal VSP of the density of the developed image in a reference pattern which is formed on the photosensitive body and the detection signal VSG of the density of the surface of the photosensitive body where the developed image is not formed. Thus, the toner is supplied without creating a runaway state.
