6.3 DRUM LOCK MECHANISM 1
When the drum unit is set in the machine, the arm [B] is pushed by the lock
pin [D] until the top of the arm [B] is locked by the stopper [C]. The lock pin
[D] is mounted on the front side plate of the main body. This completely locks
the drum unit in the machine (Fig. 1). At the same time, the top of the right
stopper [C] turns on the drum detection switch [E]. The switch [E] tells the
machine that the drum unit is set (Fig. 3).
Pulling the lever [A] to the operation side turns the stopper [C] clockwise and
disengages the arm [B]. Therefore, the lock pin [D] of the main body is also
released from the arm [B] due to spring tension (Fig. 2).
