IPC: G03G15/04
Filed: 1978-10-09
Abstract: PURPOSE: To prevent leakage of light of an exposure lamp and perform color copying free from the ground stains of copies by so providing slit opening-closing members that the plural slits for color exposure allow the passage of light only while they are making contribution to imaging.  
     CONSTITUTION: When a lever 35 is pulled by a wire 42, the lever 35 moves an opening-closing member 33a downward to right owing to the action of parallel links together with a lever 34, thereby opening a slit 3a. When the wire 42 is loosened, the lever 35 is reset by the elastic force of the spring 43, by which the slit 3a is closed. The constitution of other opening-closing members 33b, 33c is the same and these are subsequently driven by the respective wires. Since these opening-closing members prevent leakage of light while the original platen 1 is not positioned over the respective slits, the ground stains of copies may be eliminated, the degradation in the transmittance of the lens, etc. prevented and the color copying by the plural photoreceptors accomplished.

Abstract: PURPOSE:To restrict the temperature descending rate of a central tank at a low level by a method wherein the central tank, at the center of the laminated tanks, is heated to a high temperature at first, and then heat at a high temperature is accumulated in the outside tanks sequentially. CONSTITUTION:An outer frame 1, an intermediate frame 3 and a central frame 2 are constituted by an insulative material respectively, therefore, insulation of multiple layers is constituted with respect to the central tank N.

Title: Charging device of powder
Inventor: OONUMA TERUYUKI
IPC: G03G15/09
Filed: 1978-10-11
Abstract: PURPOSE:To so charge the powder whose pressure contact resistance is of the specific value that it has the specified polarity and potential meeting the purpose by using said powder and setting the specific volume resistance of the electrode part smaller than the specific resistance of the powder substrate surface part. CONSTITUTION:Performing good developing necessitates charging the toner to the same polarity. As a result of the experiment done by changing the specific volume resistance values of electrodes and the materials constituting the surface of developing rollers, the specific volume resistance of the electrode portion is set smaller than the specific volume resistance of the roller surface portion. Further, at 10<6>OMEGAcm or under of the pressure contact resistance of the toner, the time constant of the toner becomes smaller and it becomes infeasible for the toner to maintain the charges of more than a fixed quantity and therefore the pressure contact resistance of more than 10<6>OMEGAcm becomes necessary. By satisfying these conditions, the fog-free images of superior sharpness may be obtained in visualizing the electrostatic latent images.
