Abstract: PURPOSE:To enhance operating characteristics of a printing element and enable to moderate the machining accuracy of each projected part for reciprocation of the printing element, by a method wherein a return spring is engaged to a returning projected part provided on a printing element. CONSTITUTION:A leaf spring form return spring 5 is engaged with a front part of the returning projected part 2, is elastically pressed when moving the printing element 1 forward by an armature 6, and functions to return the element 1. The returning projected part 2 and a forward-movement projected part 3 are spaced from each other by a distance L, the projected part 3 is operated by the armature 6, and the projected part 2 is returned by the return spring 5. In addition, the force exerted on a guide by the armature through the printing element 1 and the force exerted on the guide by the return spring 5 through the element 1 so act as to cancel each other, so that the friction between the element 1 and the guide is moderated. Accordingly, the hindrance of the action of the printing element due to the friction and the friction itself between the element and the guide can be reduced, and an extremely smooth reciprocating motion can be expected.

Title: Method and device for reproduction of injury on optical disk
Inventor: SUGIYAMA TOSHIO
IPC: G11B7/00
Filed: 1984-02-13
Abstract: PURPOSE:To prevent the effects of an injury to be inflicted on the light spot for reading if the signal read-out surface of an optical disk is injured by applying a nonvolatile material having a refractive index approximately equal to the optical disk to said read-out surface. CONSTITUTION:The injuries of an optical disk 10 are reproduced by stroking softly the read-out surface side of the disk 10 with a coating member 11 and then attaching the silicone oil to the read-out surface of the disk 10. The silicone oil has a small level of surface extension and therefore spreads over the disk surface when it is applied to the disk 10. Thus the silicone oil can be applied smoothly on the surface of the disk 10. Then a filler 9 covers completely an injury 5 and at the same time remains thin on the disk surface. Therefore the incident light 6 is made incident on the filler 9, and the same refractive index is obtained even at an interface between wall parts 5a and 5b of the injury 5. Therefore the refracted light goes straight toward an arrow head 7. Thus the reproduction signal has no deterioration since the light quantity irradiated on the information surface of the disk 10 is not reduced.
