Title: Three-axis optical head
Inventor: MATSUI TSUTOMU
IPC: G11B7/09
Filed: 1984-12-25
Abstract: PURPOSE:To improve greatly the control characteristics of a three-axis optical head by using a plate spring bent in an OMEGA shape or a ring shape so as to secure the elasticity in the three-axis direction to hold a mobile barrel storing an objective lens at least in three directions at the periphery of the barrel. CONSTITUTION:When a focus control current is supplied to a focus coil 13, a magnetic flux produced from the coil 13 acts with another magnetic flux produced at a gap formed between a magnetic pole disk 7 and a cylindrical magnetic pole 5. Thus a mobile barrel 8 holding an objective lens 14 is moved toward an X axis. Then the radial control currents adverse to each other are supplied to radial coils 10a and 10b. Then the magnetic fluxes produced from both coils 10a and 10b act on the magnetic flux produced a gap between a radial magnet 22 and a center magnetic pole 20. Thus the barrel 8 is moved toward an X axis. Then the barrel 8 is moved toward a Y axis when the jitter control current adverse to each other are supplied to jitter coils 11a and 11b.

Filed: 1988-11-07
Abstract: PURPOSE:To prevent the input mistakes of SOROBAN (Japanese abacus) to a terminal equipment by preparing the light-sensitive sensors at the positions where the abacus beads are stopped and inputting electrically the reaction results of these sensors. CONSTITUTION:A SOROBAN 3 is used to a terminal equipment to obtain the input value. An abacus spit 4 of the SOROBAN 3 contains two light-sensitive sensors 6 at the upper stage part of the spit and five sensors 6 at the lower stage part of the spit where the abacus beads 5 are stopped respectively.
