Tape deck mechanism with main cam gear moving sub-deck, pole base loading unit, brake unit and main sliding memeber

摘要

A deck mechanism for a magnetic recording/reproducing apparatus comprises a main deck provided with a head drum, a capstan motor, and a sub-deck installed on the main deck to be loaded/unloaded. The sub-deck is provided with a pair of reel discs, onto which tape reels of a tape cassette are seated; a pole base loading unit; a pinch roller unit for compressing the tape against a spindle of the capstan motor when the sub-deck is loaded; a brake unit; a main sliding member mounted on the main deck to be capable of reciprocatingly sliding, the main sliding member controlling the driving of the pinch roller unit; and a main cam gear mounted on the main deck. The main cam gear causes the sub-deck, the pole base loading unit, the brake unit, and the main sliding member to perform linked movements while the main cam gear is rotationally driven.
