The aforementioned operation sequence is reversed to shift from the play state to the ELEV O.K. state.
A
Disc changing is carried out by shifting from the current play state to the ELEV O.K. state once, then shifting to
the next play state. For example, to change the disc 1 to disc 6, the disc 1 play status is shifted to the ELEV O.K.
status first, then the ELEV O.K. state is shifted to the disc 6 play state.
The mechanism state transition diagram is given below. Transition of the state of stage and tray group by the
elevation operation is presented in vertical direction of the diagram. Transition of the state of tray separation and
CRG position by the cam operation is presented in horizontal direction of the diagram. As shown in the diagram,
the position of tray group and stage at the time of loading and ejection is same with that at the time of play only in
the case of the disc 1.
