Abstract

PURPOSE: To realize a compact and inexpensive mechanism by additionally providing a conventional constant-driving mechanism with a rotary member which turns at a circumferential speed equal to and in the same turning direction as those of a capstan.
CONSTITUTION: In addition to pinch roller 24 and capstan 20 coming in contact with magnetic recording tape 10, rotary member 22 in the same shape, of the same size and made of the same material as those of capstan 20 is provided. In play mode or record mode of a tape recorder, pinch roller 24 is pressed against the other surface of tape 10, and capstan 20 and rotary member 22 come in contact with tape 10, so that it will be held between capston 20 and rotary member 22, and pinch roller 24. When capstan 20 is driven counterclockwise, pinch roller 24 and rotary member 22 are also turned at the same circumferential speed. Therefore, tape 10 runs at a constant speed equal to the circumferential speed of capstan 20 as shown by the arrow while tape is linear between rollers 16 and 18 and the part between capstan 20 and rotary member 22 comes in contact with the outer circumferential part of pinch roller 24.
