Abstract: PURPOSE:To prolong the life of a photosensitive body by preventing developer, a developing device, a medium to be transferred and a cleaning device from directly coming into contact with the photosensitive body. CONSTITUTION:While the photosensitive drum 11 turns in a direction shown by an arrow B, it is electrostatically charged by an electrostatic charger 12, then a protective layer 31 is stretched and stuck to the drum 11 by a protective film stretching and sticking roller 39, and image exposure is performed to the drum 11 through the protective film 31 in an exposing part 13 so as to form an electrostatic latent image. The electrostatic latent image is developed with the developer containing coloring particles by a developing part 14 to be a visible image on the protective film 31 and transferred on the medium to be transferred 17 by a transfer charger. After finishing transfer, the film 31 is peeled from the drum 11 by a protective film peeling roller 35, and taken up to a protective film take-up part 33. The medium 17 on which the developer image is transferred is destaticized by a destaticizer 29 on which AC voltage is impressed, and the image is fixed there by a fixing device 18. Thus, the photosensitive body 11 does not directly come into contact with the developer and the developing device, etc. Since the developer does not remain on the photosensitive body 11 after transfer, a cleaning part is not necessitated.

Title: Device for stabilizing light emission of fluorescent lamp
Inventor: IKEDA CHIKAMASA
IPC: H04N1/04
Filed: 1987-07-03
Abstract: PURPOSE:To always obtain the stable light emission characteristic of a fluorescent lamp, by providing a heater and a temperature switch which controls a temperature to energize the heater intermittently at a constant level regulated in advance, and maintaining the tube temperature of the fluorescent lamp at the level exceeding a prescribed temperature. CONSTITUTION:When the fluorescent lamp 1 begins to be energized and to emit light, the tube temperature rises by heat generation due to emission. Therefore, when the temperature is kept at the level exceeding the temperature to stabilize the emission characteristic by self-heating after starting emission, the temperature switch 3 is maintained at an open state. Meanwhile, when the main switch of an image scanner is turned ON while the fluorescent lamp 1 is not energized, the temperature switch 3 detects the tube temperature of the fluorescent lamp 1, and conduction to the heater 2 is controlled intermittently. Thereby, the emission characteristic of the fluorescent lamp 1 can be maintained at a stable tube temperature. Furthermore, when a state where it is impossible to cut off the conduction to the heater 2 due to the fault of the temperature switch 3 is generated and the tube temperature rises abnormally, a temperature fuse 4 is melt, then, the conduction to the heater 2 can be interrupted.

Filed: 1990-06-27
Abstract: PURPOSE:To decrease the amt. of the DC offset to be generated by setting the photodetecting area of a photodetecting element which receives a laser beam smaller than the diameter of the laser beam and quadrisecting the photodetecting surface at 45 deg. angle with a tracking direction. CONSTITUTION:The photodetecting element 10 is formed by setting the area of the circular photodetection surface smaller than the diameter alpha of the beam spot 11 and quadrisecting the photodetecting surface at 45 deg. angle with the tracking direction to from the four photodetecting surfaces A to D so that outputs are taken out of the respective photodetecting surfaces. Since the intensity distribution of the beam spot of the semiconductor laser beam complies with distribution, a tracking error signal is eventually detected in the part where the light quantity of the gaussian distribution is strongest. The DC offset quantity, such as deviation from the optical axis of an objected lens, is decreased in this way.

Title: Stabilizing device of output for semiconductor laser
Inventor: SHIBATA ISAMU
IPC: H01S5/042
Filed: 1979-12-21
Abstract: PURPOSE:To stabilize an output of semiconductor laser by a method wherein a life of laser element is not reduced and a fast reaction is made for a rapid variation of the output. CONSTITUTION:When a temperature of the laser 2 is kept constant and its output is Po, the laser beam is received at 3, the signal is amplified and a polarity of the laser is reversed at 11, and added at 12 with a reference signal 13. Thus, the output of addition 12 is in a reverse relation with the laser output and compared at 14 with a signal proportional to a laser driving current I from the resistor R. The current I is controlled so as to cause both signals to be equal with each other. In turn, Peltier element 16 is operated at 15 by the signals at both ends of the resistor R and the laser element 2 is forcedly cooled. This cooling operation is performed in reference to only a laser driving circuit I. As a result, when the output is varied, the laser driving current is increased or decreased to control the output and at the same time a temprature of the laser element is controlled in response to a degree of current, so that the output may quickly be stabilized and a deterioration of the laser element may be prevented.
