Abstract
A disc loading apparatus has a main chassis having a disc spindle and a signal transducer, a slide chassis slidably provided on the main chassis, a disc holder spring-biased towards the main chassis for inserting a disc cassette for recording and/or reproducing operation and a rotatable arm provided on the main chassis and cooperating with the slide chassis at an arc cam formed on the rotatable arm, the rotatable arm being rotated against a spring force by the insertion of the disc cartridge into the disc holder. There are further provided a center core pressing arm provided on the disc holder and spring-biased towards said main chassis for pressing a center core of the disc cassette towards the disc spindle of the main chassis at one time when the disc holder moves down to the main chassis in accordance with the rotational movement of the rotatable arm and a protect arm cooperating with the rotatable arm and the center core pressing arm for preventing an erroneous pressing action of the center core pressing arm to the center core. Accordingly, upon recording and/or reproducing, upon mis-operation of the eject member, and upon unloading, the magnetic disc can be rotated and unloaded positively and smoothly.
