Title: Image forming device
Inventor: ITAKURA HARUO
IPC: G03G15/00
Filed: 1989-11-20
Abstract: PURPOSE:To restrain the increasing of electrostatically charging potential so that the occurrence of discharging, etc., may be prevented and to prevent the malfunction of a computer circuit by connecting between the metallic part of a developing unit and a ground by a high resistance. CONSTITUTION:A high resistance member 12 formed of conductive rubber lies between the developing unit and an adjacent grounding metallic member 11. When the developing unit is inserted in a copying machine, the high resistance member 12 is automatically press-contacted since the high resistance member 12 is provided with elasticity. A high resistance R is electrically connected between the metallic member 1 of the developing unit and the grounding metallic member 11 by making the high resistance member 12 lie. In this case, the electrostatically charged charge of the developing unit is gradually eliminated, so that the voltage of the developing unit never increases to the level where the discharging, etc., is caused by a dielectric breakdown in the least. Thus, the malfunction of the computer control circuit can be surely prevented.

IPC: F16C27/00
Filed: 1989-11-20
Abstract: PURPOSE:To release decentering of a shaft, restrain vibration to a low level during the rotation of the shaft so as to enable the high speed rotation of the shaft and reduce wear at the time of starting and stopping by interposing an elastic body between a bearing body and a housing surface, and using dynamic pressure generated by the rotation of a shaft in the holding of the bearing. CONSTITUTION:A bearing body 21 is provided with grooves 24 for arranging O-rings 23 such as elastic bodies in the vicinity of both ends of the outer circumference 22 in an axial direction and grooves 6 for generating dynamic pressure such as herring bone grooves. A plurality of through holes 26 piercing the bearing body 21 in a radial direction are arranged at regular intervals on the circumference thereof. Although there is a gap between the central axes of the upper and the lower bearing bodies 21, the gap is absorbed by the elasticity of the O-ring 23 interposed between the bearing bodies 21 and a housing 2. Compressed gas is supplied to a pressure chamber 35 via a gas supply hole 36 at the time of starting and fed through a communicating hole 34 to a thrust bearing face 9 to float a shaft 1 from the thrust bearing face 9. And starting torque is thereby reduced and also wear due to contact sliding is reduced.

IPC: H04N5/235
Filed: 1993-12-01
Abstract: PURPOSE:To attain correct shading correction by changing the size of a block area for data detection on each area on a screen so as to detect data at all areas such as center and edges of the screen with proper accuracy. CONSTITUTION:Areas at left and right ends on a screen are divided half in a horizontal direction of each block in the middle areas, and the blocks are divided at an equal interval for upper and lower ends and middle areas in the vertical direction. In the case of CCD shading state, for instance an area o 1/10 from the left end of the screen is a block A1, in which a DARK 1 level is detected, an area from 1/10 to 2/10 is an A2 block, in which a DARK 2 level is detected. Similarly DARK3, 4, 5 levels are detected from A3, A4, A5 blocks respectively and a block data processing circuit calculates respective correction data. The data are stored in a shading correction memory and used in the normal operation, then the black shading in the middle of the screen is completely corrected.
