Initialized operation (without any magazine pack).
After microcomputer reset starting moves an elevator posi-
tion to the position of DISC1, and carries out initial operation.
1, Elevator motor control terminal ELV+ (3PIN) is set to L,
ELV- (4PIN) is set to H, and an elevator position is moved
downward.
2, UP SW (SW2 for IC301, 26PIN) checks H (SW2 is OFF
position).
