Abstract
A deck mechanism of a headphone stereo which is capable of minimizing a tension working on a belt and of controlling a rotation torque transmitted to a reel in an FF or REW mode by transmitting a driving force of a driving motor by a power transmission gear unit, includes a power transmission gear unit for transmitting a driving force of the driving motor, a mode selector for transmitting the driving force transmitted by the power transmission gear unit according to a selected mode, a reel driver for driving a reel according to the selection of the mode selector, a power transmission idler unit moving according to the play direction of the reel driver, and a capstan driver for driving a capstan through a belt transmission by a selective engagement of the power transmission idler unit.
Claims7
In a headphone stereo having a reel gear for driving a tape cassette, a capstan for tracking a tape in the tape cassette, and a driving motor rotatingly driving an axial gear of the driving motor, a deck mechanism comprising:
- a gear system engaged in a geared relationship with the axial gear for transmitting a driving force of the driving motor;
- a mode selector constructed and arranged to control the transmission of the driving force of the gear system in accordance with a selected mode;
- a reel driving mechanism engaged with the gear system and constructed and arranged to drive the reel gear using the driving force of the gear system, in accordance with the selected mode;
- a capstan driving mechanism constructed and arranged to drive the capstan using the driving force;
- and
- a power transmission idler mechanism in a geared relationship with said gear system constructed and arranged to selectively provide the driving force to said capstan driving mechanism to thereby drive the capstan in accordance with a rotational direction of the reel driving mechanism;
- wherein one of said gear system and said reel driving mechanism includes a torque controller constructed and arranged to control a torque transmitted to the reel in the selected mode.
