Abstract
A tape tension mechanism for a recording and reproducing apparatus having a supply reel table and a take-up reel table, in which a tension arm is provided at the supply reel side and rotatably mounted thereon, a brake mechanism for the supply reel table is coupled to the tension arm, and the tension arm is biased by a tension spring so that the brake mechanism performs a braking operation, the tape tension mechanism further includes a movable operation member to which a fixed end of the tension spring for biasing the tension arm is connected, wherein the fixed end of the tension spring is moved close to and apart from a pivot of the tension arm.

A tape tension mechanism for a recording and reproducing apparatus having a supply reel table and a take-up reel table, a tension arm rotatably provided at a supply reel side, and a brake mechanism for the supply reel table coupled to the tension arm, the tension arm being biased by a tension spring so that the brake mechanism performs a braking operation, said tape tensioning mechanism comprising:
- a movable operation member to which a fixed end of the tension spring for biasing the tension arm is coupled, wherein the fixed end of the tension spring is moved closer to and further apart from a pivot of the tension arm;
- wherein said movable operation member has an end coupled to the fixed end of the tension spring and mounted to be slidable with respect to a chassis.
A tape tension mechanism for a recording and reproducing apparatus having a supply reel and an a take-up reel comprising:
- a rotatable tension arm;
- a brake mechanism for said supply reel which is coupled to said rotatable tension arm;
- a tension spring for biasing said tension arm against a tape in said recording and reproducing apparatus;
- and
- a movable operation member having a first end coupled to said tension spring and coupled to a second spring, said second spring providing a spring force in a direction substantially opposite to the direction of the bias of said tension spring, said spring force of said second spring being greater than that of said tension spring;
- wherein said movable operation member has a second end coupled to a sliding mechanism, said sliding mechanism moving said operation member in a first direction away from said second spring and in a second direction toward said second spring.
