Patent JP-H06150517-A (JP)
Title: Disk driving device
Inventor: YOKOTA YUJI
IPC: G11B17/028
Filed: 1992-10-30
Abstract: PURPOSE:To prevent the occurrence of a rotational fluctuation by setting a prescribed relationship between the speed at which a disk of a first and a second installation mechanisms is installed to a spindle and the inertial mass of the spindle. CONSTITUTION:When an FD 210 is inserted into a driving mechanism of a panel 3, the front end abuts to a rising section 90 of a latch lever 88. As it is being pushed, the FD 210 approaches to the vicinity of an installation position against a spring 89 and the engagement between a slide edge 91 of the lever 88 and an engagement edge 82 of an eject plate 79 is disengaged. A plate 79 is moved to the position, which is controlled by a guide pin 80 and a guide groove 81, by the pulling force of a spring 83 and a roller 95, which is held to the plate 79 in a rotation free manner, is also moved to a prescribed position as it rotates. At that time, the increase in the inertial mass due to the inertialing controls the plate 79 which moves up and down on a center cone 104 and the clamp speed is controlled by a damper 85 which damps the operations. Thus, rotational fluctuation is prevented by making a prescribed relationship between the clamp speed and the inertial mass of the spindle.

Title: Sheet feeding device
Inventor: HAYAKAWA YASUYOSHI
IPC: B65H1/26
Filed: 1988-12-16
Abstract: PURPOSE:To prevent the separation of a sheet housing means from a feeding position during feeding by providing a feeding means for feeding sheets housed in a sheet housing means from the feeding position for housing and feeding the sheets in the same direction as a defined direction, and a restraining means for restraining the movement of the sheet housing means in the defined direction. CONSTITUTION:As a feed roller 4 is rotated at a defined feeding timing, a sheet on the topmost site which is in contact with the feed roller 4 is fed from a sheet housing portion 3 by the frictional force of the roller 4. Because of the frictional force, etc. between sheets, sheets may not always be fed one at a time but sometimes two/three sheets may be simultaneously fed. However, the doubly fed sheets are separated by the frictional force of the contact portion between the feed roller 4 and a separating pad 5 and fed one at a time. In this case, although the sheet housing portion 3 is subjected to a force in the separating direction due to the rotation of the feed roller 4, since the contact portion 55 of a separating pad supporting plate 51 is brought into contact with the contact portion 33 of the sheet housing portion 3, the sheet housing portion 3 will not be separated.
