PS-X6/X7

The

PS-X6

and

PS-X7

are

a

full-automatic

turn-

table

system,

which

means

that

the

tonearm

will

move

across

to

the

record

and

commence

to

play,

and

then

return

to

the

arm

rest

again

after

the

completion

of

the

record,

simply

by

the

operation

of

control

buttons.

This

cycle

of

operations

is

per-

formed

by

the

transfer

of

a

series

of

changes

from

the

main

gear

cam

to

the

main

lever.

This

series

of

changes

is

described

below.

to

assure

smooth

travel

of

also

employed

(Luminous

Record

End

Detector

Mechanism)

(see

Figs.

1-9

and

1-10)

This

record

detector

mechanism

consists

of

a

lamp,

a

photo-conductor

(CdS),

and

a

shutter

connected

to

the

shaft

of

the

tonearm.

Changes

in

position

of

the

shutter

(due

to

the

gradual

inward

movement

of

the

tonearm)

results

in

changes

in

the

amount

of

light

received

by

the

photosensitive

element.

When

the

stylus

runs

in

the

lead-out

groove

of

the

record,

the

tonearm

suddenly

moves

across

by

a

relatively

larger

amount,

resulting

in

a

sudden

increase

in

the

amount

of

light

striking

the

photo-

sensitive

element,

exceeding

a

preset

value.

An

electronic

circuit

is

consequently

activated,
