1. DESCRIPTION OF THE MECHANISM
1-1 CHARACTERISTIC OF THE K-DECK MECHANISM
1) K-MECHA DECK follows the VHS standard.
2) K-MECHA DECK uses three motors (DRUM MOTOR, CAPSTAN MOTOR and L/C MOTOR)
3) K-MECHA DECK uses L/C MOTOR to drive FRONT LOADING.
4) K-MECHA DECK recognizes each mode by using a 4-BIT MODE signal. This 4-BIT MODE signal is
generated by the CAM SWITCH which is driven by the L/C MOTOR.
5) K-MECHA DECK is operated by 7 MODES (EJECT/INITIAL/REV/IDLE/PLAY, STOP SLOW/BRAKE/FF
,
& REW).
6) K-MECHA DECK reduces the mode shifting time, that is, picture playing time by using the FULL
LOADING SYSTEM that has the DRUM wrapped by the tape.
7) K-MECHA DECK is seperated from the Main PCB. When assembling, it is connected by B-B TYPE
CONNECTOR.
The CAPSTAN MOTOR and DRUM MOTOR of K-MECHA DECK and the MAIN PCB DECK are directly
connected without using cable.
