ABSTRACT:
A cassette loading apparatus which eliminates a harness for the electric connection to a cassette insertion detecting switch. The cassette loading apparatus comprises a parallel quadrilateral link mechanism including first and second parallel links and third and fourth parallel links. A connecting pin between the first and third links is mounted on a stationary member on which the cassette insertion detecting switch is mounted. A switch operating element is provided on the third link for operating the cassette insertion detecting switch between on- and off-states. The first and second links have elongated holes formed along the length therein, and fitting pins on an actuating lever are loosely fitted in the elongated holes such that the actuating lever extends in parallel to the third link. The actuating lever is mounted for pivotal motion on a cassette holder by means of the first fitting pin and is positioned so as to be operated by a cassette inserted into the cassette holder to move between a cassette non-insertion detecting position and a cassette insertion detecting position to operate the switch operating element.
