IPC: G11B33/02
Filed: 1992-07-29
Abstract: PURPOSE:To prevent a fault from being caused by dust by providing a shutter lock means on the opening of a front panel. CONSTITUTION:When an optical disk cartridge 2 is inserted to the opening 3, a release lever 13b of the lock means 13 is pushed inside to release the lock, and the shutter 9 becomes rotatable to the upper side. So, when the cartridge 2 is pushed into the opening part 3 further, the cartridge 2 can be deeply inserted since the shutter 9 is pushed upward and the means 13 is rotated to the outside. When the cartridge 2 is pulled off, the opening 3 is blocked since the shutter 9 is being pressed by a coil spring 12 so as to block the opening 3. Also by the means 13, the shutter 9 is pressed with a leaf spring 16 so as to be locked, then a pawl 13a is engaged with the edge part of the shutter 9 to lock it in the blocked state. Thus, the opening is surely blocked, therefore, the faults caused by dust intrusion and from the contact of human body are prevented.

Title: Two-side printing device
Inventor: INUYAMA SEIJI
IPC: G03G15/00
Filed: 1987-08-13
Abstract: PURPOSE:To prevent two-side printing on double fed cut sheets by actuating a selector when double feed is sensed, and by passing the cut sheets not to the two-side printing part but to a collecting stacker. CONSTITUTION:A control part 6 rotates a pick roller 2a to pay off the uppermost cut sheet PP in a hopper 2, and when a sensor 4a senses its leading edge, a stopper 2b is put in contact with the undersurface of the cut sheet PP to hinder double feed, and the sheet is forwarded to a two-side printing part 1 by a feed roller 2c. When a double feed sensor 4b senses double feed of cut sheets PP, a selector 3a is switched upward to lead double fed cut sheets PP to a collecting stacker 3. When a collection sensor 4c senses the trailing edge of collected sheets, the selector 3a and stopper 2b are restituted, and the feed roller 2c is stopped. Thus two-side printing on double fed cut sheets is prevented.

Title: Motor control apparatus
Inventor: HIRANO TAKAHISA
IPC: H02P8/00
Filed: 1994-08-26
Abstract: PURPOSE: To enable simple setting of a sequence to drive and control a plurality of motors, by setting torque adjusting time within speed adjusting time, and turning on/off each of exciting phases according to the set torque adjusting time. CONSTITUTION: Phase A is turned on, and phase B is turned on a speed adjusting time (SC) t2 thereafter, and phase C is in turn turned on SC t2 thereafter. SC t2 after phase C is turned on, phase D is turned on, and phase A is turned on again SC t2 thereafter. Phase D is turned off a torque adjusting time (TC) t1 after phase A is turned on, and phase A is turned off TC t1 after phase B is turned on. Phase B is turned off TC t1 after phase C is turned on, and phase C is turned off TC t1 after phase D is turned on. Therefore, phases A and D are on and B and C are off for TC t1 from timing X to timing Y, and phase A is only on for a period from timing Y to timing Z, that is, a period obtained by subtracting TC t1 from SC t2. This reduces the torque of a motor and yet maintains speed for SC t2 as conventional.
