Abstract
A reel braking mechanism for each reel table in a mechanism for controlling the distance between reel tables to accommodate different sizes of tape cassettes is provided. The reel braking mechanism has reel tables, rotating arms supporting brake members, a rotating apparatus for rotating the rotating arms, and moving members for moving the brake members. The brake members rotated by the movement of the moving members can be released from the reel tables.
Claims17
A reel braking mechanism for a magnetic recording or reproducing apparatus comprising:
- a deck having first and second arcing holes;
- first and second pins, separated by a predetermined distance, fixed on said deck;
- first and second rotating arms rotatably connected with said first and second pins, respectively, said first rotating arm supporting a first reel table and said second rotating arm supporting a second reel table for moving said reel tables between first and second positions along said arcing holes;
- first and second driving arms having gear portions engaged with each other, said driving arms rotatably connected with said first and second pins, respectively;
- a driving motor for driving the gear portion of at least one of said first and second driving arms;
- connecting means for connecting said driving arms to said rotating arms to transfer a force of said driving motor to said rotating arms;
- first and second brake members rotatably connected with said first and second pins, respectively, and rotatable together with said first and second driving arms, respectively, wherein said brake members rotate to contact at least one of said first and second reel tables, thereby reducing the speed of said reel tables;
- elastic biasing means for firmly contacting said brake members to a surface of said reel tables;
- and
- releasing means for separating said brake members from the surface of said reel tables.
