Abstract
A disc driver comprises a locking plate for locking an operation button depending upon the presence or absence of an inserted magnetic disc, and a spring bridged between a tabular leg portion of the operation button and a slide lever for absorbing a shock given to the operation button locked by the locking plate and disallowing the shock to transmit to the locking plate. In place of the locking plate, a change-over lever can be employed for enabling or disabling a function of the operation button depending or the presence of absence of an inserted disc into the disc driver.
