Title: Electrostatic recording device for printing label
Inventor: MATSUDA YASUHIKO
IPC: G03G15/00
Filed: 1990-10-03
Abstract: PURPOSE:To remove the looseness of continuous recording paper by controlling a pressure varying means so as to increase the pressure of the pressure varying means varying contact pressure between a fixing roll pair by an output from a detecting means detecting the looseness of continuous recording paper. CONSTITUTION:Continuous recording paper A is carried from the left of a photosensitive drum 1, and a toner image is transferred onto a label L from the photosensitive drum 1 in a charger 6 for transfer, and fixed by a fixing roll pair 8, and the continuous recording paper is discharged. Since the layout sheet S section of continuous paper A is coated with a release agent and has a low friction coefficient and the laminating section of the label L and the section only of the layout sheet S have different thickness, slip is generated between the fixing roll pair 8 and continuous recording paper A, and looseness is generated. The output level of a light-receiving element 18 is lowered by the attenuation of the quantities of reflected light by a light-emitting element 17 and recording paper A, a light-amount level comparison circuit outputs a pressure changeover command signal when the output level reaches a comparison reference level or less, and contact pressure with an auxiliary roll 8B of a heating roll 8A is increased. Since the rotary peripheral speed of the fixing roll pair 8 is set at a value faster than that of the photosensitive drum 1 originally, the quantity of transfer to continuous recording paper A is augmented, thus removing the looseness of recording paper A.

Title: Video signal clamp circuit
Inventor: TANIZAWA MASAHIKO
IPC: H04N5/16
Filed: 1989-10-13
Abstract: PURPOSE:To eliminate distortion of a composite video signal to be outputted by providing a feedback circuit using an operational amplifier. CONSTITUTION:When a composite video signal is inputted to a video signal input terminal, a charge stored in a capacitor C1 except for a period of a horizontal synchronizing signal TH is discharged by a base impedance of a transistor(TR) 2. Since a base level of the TR 2 is lower than a reference voltage Vc at a terminal (a) for the horizontal synchronizing signal period TH, a feedback circuit employing an operational amplifier 1 is active, a diode D is conductive and the base level of the TR 2 is brought into the same level as a reference level Vc. When the horizontal synchronizing signal period TH is finished, the diode D is turned off. Thus, distortion is eliminated from both outputted horizontal synchronizing signal and vertical synchronizing signal.

Title: Paper feeder
Inventor: YOSHIDA NORITOSHI
IPC: B65H3/46
Filed: 1990-10-04
Abstract: PURPOSE:To prevent paper slipping due to the paper powder sticking to rollers by providing a brush member for removing the paper powder stuck to the rollers by contacting hair tips with the rollers. CONSTITUTION:When the start button of an image forming device body is turned on, a paper feed roller 1 and separation rollers 2 and 3 start rotation to carry the top paper. At this time, if the paper is a recycled paper, paper powder is remarkably accumulated on the separation roller 2 and 3. Since recycled paper is generally acid, paper powder is electrified to a minus side. Since a brush-like roller 4 is made of material (wool, nylon or the like) having plus side electrified property, it removed the paper powder electrified to minus while attracting the paper powder from the separation roller 3 by means of electric force. The brush-like roller 4 may be brought into contact with the separation roller 2 or paper feed roller 1.
