1. DESCRIPTION OF THE MECHANISM
1-1 Characteristic of T5-DECK MECHANISM
1) T5-MECHA follows the VHS and the NTSC standard.
2) T5-MECHA uses 3 MOTORS (DRUM MOTOR, CAPSTAN MOTOR, L/C MOTOR).
3) T5-MECHA uses L/C Motor to drive FRONT LOADING.
4) T5-MECHA uses 4-BIT MODE signal to recognize each MODE.
This 4-BIT MODE signal is generated from the cam switch driven by the L/C MOTOR.
5) T5-MECHA has 7MODES (EJECT/INITIAL/REV/IDLE/PLAY,STOP,SLOW/BRAKE/FF&REW) operation.
6) T5-MECHA deduce the MODE changing time by adopting the full loading system which maintains the
tape winding the drum circumference.
7) T5-MECHA can be separated from the main pcb, and be assembled with B-B type connector. This B-B type
connectioning means that CAPSTAN MOTOR, LC MOTOR, AC HEAD, FE HEAD, DRUM are connected
directly without using connector cable.
