Abstract:
1. A magnetic recording and reproduction apparatus, comprising: 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, the first gear member being rotatable by rotation transmitted from the driving ring gear member, and including a first gear part and a first cam part in a first single plane, the first cam part having an arcuate shape, the second gear member being rotatable by rotation transmitted from the first gear member to rotate the first ring gear member, and including a second gear part and a second cam part in a second single plane, the third gear member being rotatable by rotation transmitted from the second gear member to rotate the second ring gear member, and including a third gear part and a third cam part in a third single plane, the third cam part being shaped so as to be engageable with the second cam part of the second gear member, the first, second, and third single planes forming substantially a single plane, wherein the second cam part engages the third cam part so as to transmit rotation during an operation of the tape loading mechanism, and is pressed against a circumferential surface of the first cam part in a state where the operation of the tape loading mechanism is completed.
