Rewinding playback (VS-REW) winding torque standard
1.6 + O.GmN*m (16 + Ggfcm),
ripple 0.4mN.m (4gfcm) or less
(If torque ripple exists, read its center value.)
(3) After checking the winding torque remove the torque gauge, and remove the adhesive tape used in item (1) above (refer
to 9-3). The STANDBY mode is set automatically.
7-3.
Checking of reel base height
(l)Remove
the cassette controller assembly (refer to 9-2).
(2)Referring to 9-1, apply DC3V to the loading motor and put the system into playback mode.
(3)Taking adequate care so that the master plane does not
contact drum, running parts (guide roller, etc.), or the MIC
contacts. Fit the master plane holes to the 2 guides (A and
B) in Fig. 2.
(4)Confirm that the heights of the S reel base reel receiving
surface and the Tu reel base reel receiving surface below
the master plane top surface are within the set values,
using, for example, a slide calliper (Fig. 3).
When checking the S reel base height, press the front end
of tension post in the arrow A direction with your finger to
release the tension band, and then check the height in this
state.
Fig. 2.
(5)If the height is not within set values, replace the washer under the reel base, and adjust as specified.
Note: After the adjustment, make sure that the reel bases rotate smoothly.
