Title: Electrophotographic photoreceptor and electrophotographic device
Inventor: IKESUE TATSUYA
IPC: G03G21/06
Filed: 1995-03-20
Abstract: PURPOSE: To prevent the defect of an image such as image flowing or blurring and to eliminate the linear faulty image caused by electrostatic charge in a reverse polarity at the time of transferring by simultaneously performing exposure and electrostatic charge. CONSTITUTION: The surface of a photoreceptor drum 1 is electrostatically charged to be negative by a primary charger 2. Next, light from a semiconductor laser reaches the surface so as to form an electrostatic latent image, and the latent image is developed and made visualizable by a developing rotating body 3. Transfer paper passing a paper carrying part from a cassette is electrostatically attracted on a transfer drum 5 rotating in synchronization with the drum 1, and the developed toner image is transferred on the transfer paper according to output from a transfer charger 6. Untransferred toner remaining on the drum is scraped from the surface by a cleaner part 7. Then, charge existing on the surface of the drum 1 is discharged by a secondary charger 8 and discharging light 9 whose short wavelength component is cut.  By simultaneously performing the exposure and the electrostatic charge by using the secondary charger 8 in such a way, the electrostatic charge of the drum 1 is eliminated.

Abstract: PURPOSE: To carry sheets smoothly even when the piled sheets decrease by a method wherein a curved-surfacelike movable guide member is joined by a pin to a connecting member which makes vertical parallel movement, gearing with the vertical motion of a paper-feeding roller which is a means for detecting the surface of paper.  
     CONSTITUTION: With the decrease in piled sheets S, a paper-feeding roller lowers, while a connecting member 10 coupled with a shaft 4a also lowers without shaking, being guided by a groove provided in the vertical direction. Moreover, the guiding plate 9a of a movable guiding means 9, with its end part on the side of sheet connected with the connecting member 10, is kept in the lower position than the top sheet, and thus the sheets are carried smoothly in spite of their decrease. On the other hand, the guiding palte 9a is formed to have a gently curved surface and, in addition, is joined to the pin 15 of the end part 7a of a carrying plate through an arc-shaped long hole 12, and further the end part 7a of the carrying plate is formed to have a curved surface smaller in curvature than the one of the guiding plate 9a, which also facilitate smooth carriage.

Filed: 1983-04-08
Abstract: PURPOSE:To reduce leaking loss, by forming a suitable number of grooves in the end face of a blade which faces a shroud section in a casing so that labyrinthes are formed. CONSTITUTION:A blade 4B is formed in its end face with a groove 7 forming a labyrinth 8. With this arrangement the flow of leak is small in comparison with a blade having no groove in its end face due to the labyrinth effect by which the kinetic energy of the flow entering into the groove 7 through a gap 6 is converted into the heat energy. In order to exhibit the labyrinth effect the width (l) of the labyrinth 8 is made substantially equal to the size epsilon of the gap 6. Further, if more than two grooves 7 are formed in the end face of the balde 4B to provide a plurality of labyrinthes 8, the labyrinth effect may be moreover enhanced.
