Am wrestling with a 5 CD shuffle mechanism on a Panasonic SA CH 74
Does anyone know of a general resource for mechanical problems wth variants
of these beasts ?
This one has 5 separate platters to hold each CD.
On entry the CD sldes along the bottom ,is elevated by the laser + spinner
assembly and 4 flimsy 'ratchet' pawls hold the carrier in the elevated
position and the main slide mchanism returns the carrier to the top of the
stack of 5 after playing.
Anyway something ,undiagnosed ,causes the top level transfer to stick part
across ,cannot see what ,
with all the mechanism in active position. As a fall-back ,disabling the
pawls and associated high level slideway the carrier will move in and out at
low level for single CD operation without jams.
Unfortunately a flimsey microswitch monitors carrier across the top and i
won't know what effect non-switching of this micro will have until i
rerassemble it all.
Marvelous array of mechanisms all coming off the one motor drive or it would
be
if it worked. What sort of mind designs these mechanisms, rotary,rack and
pinion, latches, slideways,reciprocating motions
