Abstract
A magnetic recording and reproduction apparatus includes a tape loading mechanism including a driving ring gear member, first and second ring gear members for shifting first and second tape guide posts, respectively, and first, second, and third gear members engaging the driving ring gear member and the first and second ring gear members, respectively. Each of the first through third gear members includes a gear part and a cam part in the same plane. The cam part of the first gear member has an arcuate shape. The cam part of the second gear member engages the cam part of the third gear member so as to transmit rotation during the operation of the tape loading mechanism, and is pressed against the circumferential surface of the arcuate cam part of the first gear member in a state where the operation of the tape loading mechanism is completed.
