IPC: H03K19/00
Filed: 1985-11-07
Abstract: PURPOSE:To reduce the power consumption by preventing a DC current from flowing to an area between the power supply terminals not only in case the input/output voltage is kept at a constant level but in a period when the constant state of said voltage is charged. CONSTITUTION:A CMOS contains a pMOSQ1 having its -2.5V threshold value and an nMOSQ2 having its +2.5V threshold value. When the input voltage Vi is lower than +2.5V, the pMOSQ1 and nMOSQ2 are turned on and off respectively and the output voltage V0 is approximate to +5V. While the pMOSQ1 and nMOSQ2 are turned off and on respectively if the voltage Vi is higher than +2.5V and the voltage V0 is approximate to the earth potential. Thus the function of a NOT gate is secured.

Title: Color image forming device
Inventor: TERADA HIROSHI
IPC: G03G15/01
Filed: 1988-10-05
Abstract: PURPOSE:To improve reliability by providing a rack which maintains developing devices and can be drawn out from a main body. CONSTITUTION:When a latent image is written first on a photosensitive body 11, a developing part 30 is set in black color. Besides, only the K developing device 34 is adjusted to the photosensitive body 11 with the aid of an eccentric circular cam 38 and other developing devices are in separating condition. The developing device 34 is separated after the photosensitive body 11 approaches before exposure starts and is developed. When the tip of a black toner picture arrives at the irradiated position with a laser beam, the beam is modulated according to a yellow signal and exposed from above a black-colored toner picture. An latent image made by the yellow signal is developed only to yellow toner since only the Y developing device 31 in the developing part 30 is adjacent to the photosensitive body 11 and the other are separated. Formation of latent images, development, and electrification by a magenta signal and a cyanogen signal are repeated in the same manner. Each of the developing devices 31-34 is housed in the developing rack 41, which is drawn out from the main body with the aid of a handle 101. Consequently, the developing part can be easily drawn out from the main body and the maintenance in high reliability can be possible.

IPC: H04N1/387
Filed: 1985-11-08
Abstract: PURPOSE:To improve the editing and copying efficiency by supporting turnably an original holding plate by an exterior part of an editing device to press an original when the tip of the holding plate is put on an input panel and moving up the tip of the holding plate immediately before the tip of the holding plate is removed from the input panel to release the pressure of the original. CONSTITUTION:A projection 16 of an original holding plate 13 is guided by an inner cam 24 while the tip 18 of the plate 13 is sliding on an input panel 8. Thus an original is kept pressed. When the tip 18 slides to the positions excluding the upper surface of the panel 8, e.g., at a position a, a projection 17 is guided by an outer cam. Thus the tip 18 moves up and is locked in a state distant away from an exterior part 12 set higher than the panel 8. As a result, the picture information can be supplied over the entire area of the original with no obstacle existing in an input mode of the picture information.
