Title: Optical disk cartridge
Inventor: KANEDA NORIYA
IPC: G11B23/02
Filed: 1992-05-18
Abstract: PURPOSE:To suppress the dust adhesion to an optical disk by preventing the electrification of the case of the optical disk cartridge. CONSTITUTION:A member (conductive material or the like) 3 which is not electrified is applied or stuck to at least the inside surface of the case 2 made of nonconductor plastic. The case 2 itself is formed of the conductive member. As a result, the inside surface of the case 2 is not substantially electrified and, therefore, the optical disk 1 in proximity to the case 2 is hardly electrified. The generation of Coulomb force between dust and the optical disk does not arise even if wind contg. the dust flows into the part near the optical disk 1 and the adhesion of the dust to the optical disk 1 is suppressed. The effect is higher if the surface of the optical disk 1 is subjected to the antistatic treatment as well.

Abstract: PURPOSE: To provide a fixing roll of less decrease in the surface temperature of the roll and good thermal efficiency at the fixing by constituting the offset preventing layer of the fixing roll by a resin layer mixed with ≥1wt% metal powder as a filler.  
     CONSTITUTION: A fixing roll 1 is formed by a heater 2, a metal core 3, an elastic material layer 4 and an offset preventing layer 5. The offset preventing layer is formed by the silicone RTV rubber, silicone resin, silicone fluoride rubber, fluorine resin or the like mixed with ≥1wt% Cu, Al, iron oxide, iron oxide red, etc. and ≥3wt% carbon powder and inorganic powder of high packing density.

Abstract: PURPOSE:To prevent the different type of a cassette, etc., from being loaded into a recording and reproducing device by locking the lid of a front loading mechanism by an optical sensor so as to be opened only when a regular cassette is regularly inserted. CONSTITUTION:When a regular large cassette 10 is inserted to a cassette port 1, infrared rays emitted from respective light emitting elements 14 are shielded by the cassette 10 not to be received by respective light receiving elements 15 and 2, and the outputs of optical sensors 41-44 are amplified by amplifiers 45-48 to be compares. since the infrared rays are shielded for the optical sensors 41 and 42 and the optical sensors 43 and 44, respective lock levers 6 and 16 for large and small openings are rotated, and lids 4 ad 13 release the lock so that the cassette can be moved in the direction of an arrow B. Then, respective plangers 7 and 17 are returned to lock the lids 4 and 13. Thus, even when trying to insert the cassette further after the cassette 10 is already loaded, the lids 4 and 13 are locked to prevent the cassette from being double inserted.

Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To reduce the user's sense of incompatibility by removing a change in the brightness of a liquid crystal(LC) screen in a mode for displaying a noiseless search image or a still image on the screen, with respect to a mode for displaying a normally reproduced image. SOLUTION: In normal reproduction, video signals are continuously written in an LC display circuit 21, and the brightness of the circuit 21 is controlled based on the value of a reference brightness register 23 set up by a user. In a special reproduction, video signals are discontinuously written in the circuit 21, which is controlled so as to be relatively darker than the value of the register 23. Consequently, the difference in the brightness of the circuit 23 between normal reproduction and special reproduction is removed, and a user's source of incompatibility can be reduced.
