Title: Passage changeover mechanism for printer medium
Inventor: MATSUURA TERUAKI
IPC: B65H20/02
Filed: 1987-06-15
Abstract: PURPOSE:To perform setting of a roll-shaped medium smoothly at the time of setting the medium by moving a platen in the direction to part from a printing head and at the same time retracting a pinch roller from the platen. CONSTITUTION:At the time of setting a medium, a roller cam 55 is rotated by a specified amount. Then a platen base 52 retracts in the direction D resisting an urging force of a return spring 56. Being linked with this motion, a lever 53 where a pin 60 and an elongated hole 59 are engaged with each other, resisting an urging force of a spring 54, rotates counterclockwise, and a pinch roller 43 retracts form a platen 42 by a specified amount. As a result, a double-folded front end of a reeled-out medium 100 passes through a gap between the platen 42 and the pinch roller 43 without jamming. Jamming is thus prevented form occurring.

IPC: G11B11/105
Filed: 1987-06-15
Abstract: PURPOSE:To quicken a recording operation by erasing other area when recording is applied to one recording area of a magneto-optical recording medium. CONSTITUTION:Suppose that recording is applied to a sector A at the preceding recording in sector pairs A, A' to apply recording, recording is applied to the sector A' this time. Then the beam spot 4 is subjected to intensity modulation by an information signal and a prescribed intensity is applied to a beam spot 3. Thus, the sector A is magnetized uniformly in a direction of the bias magnetic field and erased. Conversely, the direction of magnetization is changed in response to the information signal (magnetized uniformly in reverse direction as the direction of the magnetic field before recording) and recorded. That is, since at least one recording area is erased in advance, the recording is started quickly.
