Abstract

PURPOSE:To obtain a thinned signal reader by providing a shield material indicating a Meissner effect between a signal reading head and a motor for driving a rotating cylinder for rotating the head. CONSTITUTION:A fixed cylinder 11 is fixed to a mechanism chassis and a rotating cylinder 2 is rotated by the motor 3 using a shaft 8 in common. This motor 3 is constituted of a printed board 12 fixed to the fixed cylinder 11, a motor coil 5 disposed on the printed board 12 and a rotor consisting of a rotor yoke 7 and a rotor magnet 6. The shield material 4 is fixed between a part for generating a magnetic flux by the motor of the motor coil 5, the rotor magnet 6 or the like on the fixed cylinder 11 and the head 1 by a bonding agent or a screwing. Since this shield material 4 is made of the material indicating the Meissner effect, it does not pass the magnetic flux to operate as a complete magnetic shield plate. Accordingly, the thinned device by approaching the rotating cylinder 2 to the motor is obtained.
