Filed: 1984-09-19
Abstract: PURPOSE:To prevent the damage of recording and reproducing heads by allowing a housing to fall toward a chassis when a notch is detected on a disc cartridge inserted to the housing and stopping insertion of the cartridge when the notch is not detected. CONSTITUTION:When a disc cartridge 5 is inserted to a housing 1 in the regular direction, a pressing part 55 of an erroneous insertion preventing device 51 is pressed vertically in the figure by a notch 38 provided on the cartridge 5, and an engaging piece of the device 51 and an engaging piece 53 stood on a sliding plate 50 are disengaged from each other. The sliding plate 50 is moved by a return spring 15, and an attaching pin 7 is moved along an inclined groove 13 provided on the sliding plate 50, and the housing 1 falls to set the cartridge 5 onto a turntable. If the cartridge 5 is inserted erroneously, the corner part of the cartridge 5 is engaged with the device 51 to stop insertion of the cartridge 5. Thus, the trouble is prevented that the housing falls because of the fault of the device 51 and the cartridge is brought into contact with recording and reproducing heads.

Filed: 1989-07-27
Abstract: PURPOSE:To form a circuit, which generates each curved line segment from input data, in a minimum storage area by inputting the coordinate data of a final control point for the inputted curved line segment into a curved line generating means, generating the data of the following curved line segments and writing the data into a storing means. CONSTITUTION:When the coordinate data for an (n+1) pieces of control points in the first curved line segment are inputted to a data input means 21, these data are transferred to a curved line generating means 24 and the coordinate data for the n-pieces of the control points are written into a storing means 22. The curved line generating means 24 generates the curved line segments from the coordinate data and outputs the segments to a data output means 25. In order to generate the next curved line segment, the coordinate data for the final control point of the curved line segment next to the inputted segment are transferred to the curved line segment generating means 24 and written into the storing means 22. Thus, the coordinate data of the unnecessary head control point are successively updated to the coordinate data of the final control point in the following curved line segment to be inputted. Then, since the coordinates for the n-pieces of control points are always stored, the minimum storage area is made enough.

Abstract: PURPOSE:To enable the number of parts materials and assembly man-hour to be reduced and obtain a large deceleration ratio by constituting a title item with an inner-tooth gear which is fitted to an operation spindle, an inner-tooth gear which is provided opposite to it, an epicyclic gear which is engaged to both, and a gear which is mounted to a motor spindle which is engaged to it and then mounting an LED to the inner-tooth gear and lighting it from a penetration hole of the operation spindle toward outside. CONSTITUTION:When a motor spindle 26a is rotated, a pinion gear 27 which is mounted to it is rotated and an epicyclic gear 25 which is engaged to it is subjected to epicyclic motion. The epicyclic gear 25 is simultaneously engaged to a friction gear 22 and an inner-tooth gear 17 at an outside. thus resulting in rotary deviation and deceleration since both 22 and 17 have slightly different number of gears at this time. Then, when an operation spindle 16a with a penetration hole at a center is rotated, an inner-tooth gear 17 where an LED 18 is mounted is rotated and the epicyclic gear 25 and the friction gear 22 are simultaneously rotated at this time, thus obtaining an improved operational feeling when operating the operation spindle 16a since the friction gear 22 has a fully heavy rotary torque with a motor-mounting fitment 24.
