Description of the MD-3 mechanism
With the plate button
pressed, the trigger lever (PLAY ) moves in the direction of the arrow <-
(1), the gear (PLAY ) is released from the boss of the trigger lever (PLAY ) engages with the gear flywheel and rotates in the direction of the arrow
<- (2), the boss (A) of the gear (PLAY ) touches the trigger lever (PLAY ) and the gear stops rotating.
When the gear (PLAY )
rotates, the lever (PLAY ) moves in the direction of the arrow <- (3)
along the cam groove on the rear of the gear to push up the operation chassis
in the direction of the arrow «- (4). The
PLAY button which has been locked is released by pressing the STOP button,
the trigger lever (PLAY ) moves in the direction of the arrow *- (5), the
boss (A) of the gear (PLAY ) is released and the PLAY operation stops.
Description
of the FF Operation
When
the FF button is pressed, the trigger lever FF moves in the direction of the
arrow (1), the boss of the gear FR cam is released and engages with the gear
wheel to rotate in the direction of the arrow. <- (2), the boss (A ) touches
the boss of the trigger lever FF and the gear FR cam stops. The FR lever B
moves in the direction of the arrow «- (3) along the groove of the gear FR
cam, the FR lever B moves in the direction of the arrow <- (3), the FR
lever C compresses the gear of the FR lever Ass'y against the Take-up
reel disc ass'y to perform the FF operation.
REW
Operation
When
the REW button is pressed, the trigger lever REW moves in the direction
of the arrow <- (1) and pushes the lever REW in the direction of the arrow <- (2). The trigger lever FF releases the boss A of the gear at that
time, the gear FR engages with the gear flywheel, rotates in the direction of
the arrow <- (3), boss B touches the trigger lever FF and rotation
stops. The FR gear B is moved in the
direction the arrow «- (4) by means of the cam of the gear FR following the
rotation of the gear FR , pulls the FR lever C in the direction of the arrow
«- (5) and moves the FR lever ass'y in the direction of the arrow <- (6) to
rotate the Take-up reel disc reel disc ass'y to perform the R E W operation.
Description
of the PAUSE Operation
When
the PAUSE button is pressed, the trigger lever PAUSE moves in the
direction o f the arrow *- (1), the boss A of the gear PA U SE is released,
engages with the gear flywheel and rotates in the direction of the arrow <-
(2), the boss B touches the trigger PAUSE and rotation stops. The PAUSE lever moves in the direction of
the arrow •*- (3) along the cam groove of the PAUSE gear at that time. The PLAY idler lever and the pinch lever ass'y is moved to perform the PAUSE operation
at that time.
When the PAUSE button is pressed again, the button is released from locking
and simultaneously the boss B of the gear PAUSE is released from the trigger
lever PAUSE and the PAUSE operation is released.
REC
Operation
When
the REC and PLAY buttons are pressed simultaneously, the trigger lever REC
moves in the direction of the arrow +- (1 ).
The PLAY operation is performed simultaneously at that time, so the REC
lever driver moves in the direction of the arrow «- (2),
pushes the lever RECA, B in the direction of the arrow <- (3), the
interlocked slide REC plate pulls the rod, the slide switch is operated and the
unit enters the R E C mode. When one of
the STOP, FF and REW buttons is pressed, the REC trigger lever is released
from the REC lever driver and only the REC operation is released.
Description
of the Auto-stop Operation
The
motor rotation is transmitted to the gear auto-kick of the MD-3 mechanism via
the slip pulley FR ass'y. The slip disk
presses the lever auto A in the direction of the arrow <- (1) when the
Take-up reel disc ass'y is rotating, so the boss of the lever auto A moves
along the cam (A) groove of the gear auto-kick.
When the reel discs (S, T sides) stop, the lever auto A stops in the condition
being moves in the direction of the arrow (2).
The cam (B) of the gear auto-kick moves the lever auto A in the direction
of the arrow «- (3), operates the plate auto-kick in the direction of the arrow
«- (4) to release the plate lock and performs the AUTO STOP operation.
