PURPOSE:To load a 4-channel rotary transformer without enlarging the outside circumferential shape, by placing two 2-channel rotary transformers on the upper and lower parts of a fixed cylinder for supporting a rotary cylinder and also guiding the running of a tape. CONSTITUTION:A fitting means of magnetic heads 2a, 2b to a rotary cylinder 3 is made to adhere to base materials 6a, 6b and is fixed by screws 7a, 7b. A fixed cylinder 21 is provided with ball bearings 11a, 11b for supporting a hollow shaft 28 fitted in the upper and lower directions, a guide stage 21a for guiding a tape 1, a stator 22a provided opposingly on the upper end face by providing a small gap on a rotor 30 of a rotary transformer provided on the lower end face of the rotary cylinder 3, and a stator 22b of the rotary transformer stuck to the lower end face. The stators 22a, 22b of said rotary transformers have a signal transmission line of 2 channels, respectively. |
