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. 2 1-2 Wire Diagram 1-3 Connector Pin Arrangement 3 2.

In order to effectively maintain the excellent performance and fully utilize the features of this apperatus and to lengthen the life of mechanism and tapes, we strongly urge you to perform the periodic maintenance and inspection as described below. · Following should be done after the substition of parts of deck or correction of deck failure. B. Cleaning of the DRUM TOTAL ASS`Y - Slowly turnning DRUM TOTAL ASS`Y, wipe the drum surface with clean cloth soaked in alchol. (Don't connect the power when turnning the UPPER DRUM) - Don't wipe the Head-Tip vertically with cleaning cloths. C. Tape transport
