Abstract: PROBLEM TO BE SOLVED: To obtain a stable data reproducing output by setting the weight of a chucking pulley at a specific value against the weight of an optical disk and thereby suppressing the focus resonance of the disk caused by an optical pickup. SOLUTION: A ring-shaped weight 43 is stuck to the outer peripheral position of a chucking magnet 39, on the circular plate 37a of a chucking pulley 37, with its weight designed to be 14-22 g, which is equivalent to 1 to 1.5 times the weight of about 16 g of the optical disk 1, and with the chucking force of the chucking magnet 39 set to be about 3 times or 220 g. As a result, the oscillation frequency of the optical disk 1 during the skew operation is greatly reduced at any position among the outermost, intermediate and innermost circumference, enabling the resonance frequency of the optical disk 1 to be largely shifted from the resonance point against a movable chassis and a skew adjusting plate, attenuating the resonance phenomenon of the optical disk 1, suppressing the focus resonance, and making stable focussing possible.

IPC: G03G15/08
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To stabilize operation of an agitating bar and to prevent dim print from occurring without making it impossible to detect toner residual. SOLUTION: This electrophotographic printer includes an image carrying body, a toner carrier making development by sticking toner on the image carrier, a toner chamber 19 for stowing toner, a conductive area 36 formed on the inner circumferential surface of the toner chamber 19, and a high tension power source impressing the same high tension polarity as that of the toner on the conductive area 36. In this case, when the conductive area 36 is impressed with high tension of polarity same as that of the toner and the inner circumferential surface of the toner chamber 19 is charged, it deteriorates and the toner electrified with opposite polarity to that of the toner becomes the normal toner, therefore there is no chance for the normal toner to stick to the deteriorated toner. Consequently, toner can be prevented from hardening into a mass.
