Filed: 1986-09-22
Abstract: PURPOSE:To simplify the structure of the moving mechanism of a head rum by providing a cam whose displacement varies linearly and reciprocating the head rum in an axial direction by this cam. CONSTITUTION:The reciprocating motion in the upper and lower direction of a rotary head drum 10 is synchronized with the rotary movement of the drum 10, the timing performing an electrification to a magnetic head 12 is postponed according to the vertical movement of the drum 10 and a track is thus formed on the surface of a magnetic tape. When the movement is performed up to the upper end part of a magnetic tape by recording along a track down or up by the magnetic head 12, the displacement of a cam 31 is reversed and a track is recorded to the upper or lower part his time. And when coming to the lower end, the displacement of the cam 31 is again reversed. When a motor 29 is rotated in a fixed direction at a constant speed, the drum 10 and a stationary drum 13 perform a reciprocating motion in the axial direction at a constant speed and the reciprocating motion can be achieved without reversing the motor 29. No wear, etc., are caused because the displacement of the cam 31 is received with a roller contact by a cam follower 32.

Abstract: PURPOSE:To provide an electric wire structure body having a noise restraining effect to both the electromagnetic and electrostatic induction by pair-twisting a third electric wire at the same phase as that of a first electric wire on a low-electric potential side to a twist-pair electric wire by first and second electric wires. CONSTITUTION:First and second electric wires 1 and 2 form a pair of a twist-pair electric wire. A third electric wire 3 is pair-twisted to this twisted-pair electric wire at a phase same as that of the first electric wire 1 on a low-electric potential side. The first electric wire 1 is connected to the earthing terminals of driving IC4 and receiving IC5. Both the ends of the second electric wire 2 are connected to the output end of rhe driving IC4 and the input end of the receiving IC5 respectively. The third electric wire 3 is connected to earth electric potential in the vicinities of the driving IC4 and receiving IC5 respectively. To electromagnetic induction, noise can be restrained by changing polarity induced by the even number or the odd number of sections L1, L2,...L5 respectively to cancel each other. To electrostatic induction, noise restraining effect can be caused also to electrostatic capacity because the third electric wire 3 becomes asymmetrical electrostatic capacity to the first and second electric wires 1 and 2.
