Title: Disc holding mechanism
Inventor: MIZUNOE KATSUZO
IPC: G11B17/054
Filed: 1985-07-05
Abstract: PURPOSE:To discriminate automatically the loading state of a disc and to prevent damage to the disc by providing a hub part made of a magnetic substance to the disc and detecting the change in leakage magnetic flux from a magnet provided to a turntable at disc loading. CONSTITUTION:When the disc 5 is parted sufficiently from the turntable 4, leakage magnetic flux from a permanent magnet 3 is caused and a Hall element 1 detects the magnetic flux 7. Then the disc 5 is approached while being loaded to the turntable 4, as the disc 5 approaches the turntable 4, the leakage magnetic flux detected by the Hall element 1 is increased and the magnetic flux detected again from a specific gap is decreased. When the gap (h) between the hub 2 of the disc 5 and the permanent magnet 3 is nearly 1mm, the leakage magnetic flux from the permanent magnet 3 flows to the Hall element 1 via the hub part 2, then the leakage magnetic flux detected by the Hall element 1 starts increasing, and when the gap (h) approaches 0.1mm, a closed magnetic path is formed between the permanent magnet 3 and the hub 2 to reduce the leakage magnetic flux to the Hall element 1 is reduced.

Title: Thermal transfer ribbon cartridge for thermal printer
Inventor: FUJIWARA YUKIRO
IPC: B41J35/08
Filed: 1984-07-17
Abstract: PURPOSE:To prevent relative slippage from occurring between a thermal transfer ribbon and a paper and thereby securely prevent smudging from occurring, by a construction wherein a thermal transfer ribbon is bent by a tensioning spring so as to damp a drawing-out force abruptly exerted on the ribbon at the time of heat loading. CONSTITUTION:The tensioning spring 17 produced by curving an elastic film form member into a ring form is provided between a ribbon passage 16 and a guide roller 14. The tip of the spring 17 is formed as a ring body so as to curve the thermal transfer ribbon 9 with a relatively large curvature. When the ribbon 9 is drawn out by an amount corresponding to the displacement of a thermal head at the time of head loading, the tensioning spring 17 is bent so that the ribbon 9 can be drawn out without resistance, and a rotating force is applied to a ribbon payout shaft 11. Accordingly, though the drawing-out force is exerted on the ribbon 9 due to the movement of the carriage simultaneous with head loading, the drawing-out force on the ribbon 9 is damped through the deformation of the tensioning spring 17, and the ribbon 9 is prevented from slipping relatively to the paper.
