Title: Image recording device
Inventor: IZAWA KUMIKO
IPC: B41J2/52
Filed: 1989-01-09
Abstract: PURPOSE:To obtain excellent gradations and stable image density by controlling the potential of the surface of an image formation body which is exposed when a video signal has a maximum value into an unsaturated potential range. CONSTITUTION:An electrostatic charger 21 while applying a high voltage to a discharging wire 211 freely controls the electrostatic charging of the surface of the image formation body 10 with a bias voltage (grid voltage) applied to a grid 212 and also perform uniform electrostatic charging. The potential of the surface of the image formation body 10 which is exposed when the video signal has the maximum value is controlled into the unsaturated potential range. Thus, the potential of the exposed part of the image formation body 10 is suppressed in the unsaturated range and the output of a semiconductor laser 51 is lowered and used. Consequently, an image which has excellent gradations and copy density of less variation due to environment of temperature and humidity can be obtained.

Title: Auto-focusing device
Inventor: AKASHI AKIRA
IPC: G03B13/36
Filed: 1987-01-12
Abstract: PURPOSE:To improve the operability of the titled device in a continuous photographing state by restricting the accumulation time of a focus detecting sensor in focusing operation in the continuous photographing state of a camera. CONSTITUTION:When the luminance of an object is low in the focusing operation under the continuous photographing state, the accumulating time of a sensor is expanded, the focusing operation is delayed in accordance with the expanded time and the photographing of the succeeding frame is also delayed. Thereby, a microcomputer PRS restricts the accumulation time of the focus detecting sensor SNS in the focusing operation (input of an object image, processing of a focus detecting signal and lens driving) under the continuous photographing state of the camera. Consequently, the focusing operation improving the operability in the continuous photographing state can be attained.
