None • When the position of the selection
mechanism just before switching to disc
selection operation os DCNT terminal =
"L". (Normally, DCNT terminal = "H"
exists when the selection mechanism is
stopped, so that it can be assumed that
the position of the mechanism has
deviated for some reason. There is the
possibility that a position deviation of the
mechanism can cause a defect of the
mechanism.)
None • At the time of movement of the selection
mechanism, a deviation has occurred
between the present position of the disc
and the disc position according to position
detection. (It can be assumed that the
waveform at the DCNT terminal and/or
at the DPOS terminal has been
miscounted. When a miscount occurs, a
discrepancy occurs between the
displayed disc No. and the counted disc
position.)
None • When the position of the mechanism
TE
L 13942296513
became DCNT terminal = "L" during disc
loading. (Normally, DCNT terminal = "H"
exists when the selection mechanism is
stopped, so that it can be assumed that
the position of the mechanism has
deviated for some reason. There is the
possibility that a position deviation of the
mechanism can cause a defect of the
mechanism.)
None • At the time of shifting to a different disc
after play completion, the pickup does
not return to the innermost circumference.

7.1.3 EXPLANATION OF DISC DETECTION
1. Detection of the rack position
There are two types of slits on the rear of the rack, and their
combination is used to find which disc has been selected during
rack rotation. The input ports (DCNT, DPOS) are as follows.
