Technical Information

This recorder is adopted with the full auto stop mechanism, MULTI MUSIC SCANNER and timer standby facility.

Full Auto Stop Mechanism

When the tape is finished in any mode: playback, record, fast forward and rewind, the tape transporting mechanism stops and the corresponding control buttons return to their normal positions and the power is shut off.

MULTI MUSIC SCANNER (Automatic program selection facility)

Newly developed MULTI MUSIC SCANNER (MMS) can select the next or preceding program, skipping the present program.

The MMS mechanism operates by detecting non-recorded sections on the tape. (Non-recorded sections of 3~4 seconds)

Timer Standby Facility (Timer recording and playback)

The facility can perform recording or playing back at any desired time by using an audio timer.

The PAUSE button is automatically released and the recording or playing back starts when the power is applied from the timer.

Circuitry of MMS and Auto Stop Mechanism

Page 4

A. Auto Stop Mechanism

The tape stop is detected by the Hall element (HG) which is located in the magnetic field of ring magnet: the magnet is connected to the shaft of the tape counter and it is rotating while the tape is running. The Hall element generates the sine wave signal by rotating magnet while the tape is running.

When the input signal of the IC1 has stopped, the logical level of the No. 6 terminal becomes "L" (low) level.

If the No. 6 level become "L", voltage difference occures across the solenoide, so that the current flows through the solenoide and the plunger functions to stop the mechanism.

B. MMS Operation

In the MMS mode, switches S1 (or S2), S3 and S5 have been ON position and the transistor X4 has been OFF state.

The logical level of the terminal No. 6 of IC2 changes in accordance with the input signal level of terminal No. 1: If the input level is more than -50dBs ±5dB, the terminal No. 6 becomes "H" (High) level. If it is less than -50dBs ±5dB, becomes "L" level.

While the signal from the tape being supplied to the No. 1 terminal of IC2 the terminals No. 2 and No. 6 become "H" level.

When the input signal has stopped, i.e. a non-recorded section between programs on the tape has positioned to the play/record head, No. 6 terminal changes into "L" level.

If No. 6 terminal has been "L" level, the current flows across the solenoide and the plunger functions to stop the MMS mechanism.

C. Timer Standby Facility

In the timer standby mode, switches S3, S4 and S6 are in the ON position and the power supply is cut off.

When the power supply turns on at the time set by the timer, the No. 2 and No. 6 terminals of IC1 become "L" level, as the capacitor C2 has not been charged, so that the solenoide functions to release the PAUSE button. And the recording or playing back starts.

D. Prevention Circuit Against Double Action

1. When the PAUSE button is released

At the moment when the PAUSE switch S4 is turned off by releasing the PAUSE button, the capacitor C4 is charged by the current flows through X5 and D6, so that the transistor X5 turns ON state.

The collector current of X5 raises the level of No. 2 terminal of IC1 into "H" level, so that the No. 6 terminal changes into "H" level.

When the terminal No. 6 becomes "H" level, the current flows through the solenoide is cut off and the plunger is prevented from functioning once again.

2. When the CUE or REVIEW button is released

At the moment when the switch S1 (or S2) turns off, while the switch S3 is ON, transistor X6 becomes ON state and the capacitor C5 is charged by the current flows through X5, so that the X5 changes into ON state.

The proceeding process is the same as the preceding item "1. When the PAUSE button is released".

E. Indicator Flicker Circuit

The transistors X2 and X3 construct the multivibrator circuit. The multivibrator is a relaxation oscillator and drives the MMS indicators to flicker.

The transistor X8 acts as a switch to flicker the PAUSE indicator.

F. Ripple Filter

The transistor X1 constructs a ripple filter which is designed to reduce the ripple current flowing through the Hall element.

G. Anti-Pause Killer Circuit

In the fast forward or rewind mode, to function the auto stop mechanism though the PAUSE button has been depressed, the anti-pause killer circuit stops the current supplying to the No. 2 terminal of IC1 by switching the transistor X7 off.

Adjustment of Cassette Mechanism

Timing of Auto Stop Motion

1. The auto stop mechanism should function at the moment when the tip of stop detect contact has been moved within 0.5 to 1.8mm in the playback mode
If the timing is more than 1.8mm, bend the part (A) of stop detect lever to the B direction. If it is less than 0.5mm, bend the part (A) to the C direction.

Fig. 15

Detection pressure of Auto Stop Mechanism

Setting the mechanism vertically in the playback mode, the auto stop mechanism should function at the pressure of 45 to 65g when the tip of stop detect contact has been pulled upwards by a tension gauge. (Refer to Fig. 16)
2. If the pressure is less than 45g, bend the adjusting arm to the A direction. If it is more than 65g, bend to the B direction.

Fig. 16

Thrust of Flywheel

The clearance between the top of flywheel shaft and the flywheel bracket should be within 0.1 to 0.4mm. If the clearance is beyond the limits, adjust the screw for normal value.

Note: After adjustment, fix the screw with lock adhesive.

Fig. 18

Pause Mechanism

1. In the playback mode, check to see that the pinch roller separates from the capstan shaft and stops turning and then the reel disk stops turning and the tape stops when the PAUSE button has been pressed. Check to see that the tape restarts and is normally transported when the PAUSE button is released.
2. If the timing of pause mechanism is out of order: the takeup reel disk stops first and then the pinch roller stops, so that the tape is projected from the cassette half.

Adjust the timing by bending the part (C) of pinch arm lever to the A direction.

3. The space between the pinch roller and the capstan shaft should be more than 0.5mm. If it is less than 0.5mm bend the part (C) to the A direction, and if it is excess bend the part (C) to B direction.

Cue & Review Mechanism

1. Timing of Cue, Action
a. In the playback mode, if the CUE button is gradually pressed, the pinch roller stops turning first and then the takeup reel disk stops. If the CUE button is released, the takeup reel disk turns first and then the pinch roller rotates.
b. If the timing is out of order, adjust it as follows
- If the tape is projected from the cassette half at the beginning of cue action, adjust it by bending the part (C) of pinch arm lever to the A direction as shown in Fig. 19.
- If the tape is fast forwarded at the beginning of cue action, bend the part (C) to the B direction as shown in Fig. 19.

2. Timing of Review Action

a. In the playback mode, if the REVIEW button is gradually pressed, the pinch roller stops turning first and then the takeup reel disk stops. If the REVIEW button is released, the takeup reel disk turns first and then the pinch roller rotates.
b. If the timing is out of order, adjust it as follows
- 1) If the tape is projected from the cassette half at the beginning of review action, bend the part (C) to the A direction as shown in Fig. 19.
- If the tape is fast forwarded at the beginning of review action, bend the part (C) to the B direction as shown in Fig. 19
- Notes: 1. After adjustment, if the pinch arm lever has been bended, check the pause timing and check that the gap between the pinch roller arm and pinch arm lever is more than 0.2mm when the REVIEW button is pressed in the recording mode.
  - 2. After adjustment check that the gap between the RQ boss and the pinch roller arm plate is within 0.7 to 1mm. If it is beyond the limits, adjust it by bending the part (D) of pinch roller arm plate as shown in Fig. 19.

Location of Heads

The play/record and erase heads should be positioned as shown below in the playback mode.

Fig. 20

Pressure of Pinch Roller

1. Setting the mechanism vertically in the playback mode, the pinch roller should stop turning at the pressure of 350~500g when the pinch roller arm has been pulled upwards by tension gauge as shown in Fig. 21.
2. If the pressure is out of limit, change the pinch roller spring.
- Note: If the pressure is excessively high, it may cause the noise from the pinch roller bearing and defective in wow and flutter. If the pressure is defectively low, it may cause defective in Auto stop motion and in wow and flutter.

How to Fit Dial Cord

Adjustment of F.F. & Rewind Torque

1. Fast Forward Torque

In the fast forward mode, check that the F.F. torque is within 100 to 160g-cm by applying the torque gauge to the take-up reel disk.

a. If the torque is less than 100q-cm, adjust as follows.

If the rotation of F.F. idler which is contacted with the flywheel stops or fluctuates when the take-up reel disk is stopped turning by the fingers, bend the part A of F.F. button lever to the C-direction.
If the F.F. idler contacted with the flywheel is turning constantly when the take-up reel disk is stopped turning, turn the three-flap clutch spring plate counterclockwise (1→2→3→4) to obtain the proper torque.
b. If the torque is over 160g-cm, turn the clutch spring plate clockwise (4→3→2→1) to obtain the proper torque.

2. Rewind Torque

In the rewind mode, check that the rewind torque is within 100 to 160g-cm by applying the torque gauge to the supply reel disk.

If the torque is out of standard, adjust it as same method as items a. & b. of "Fast Forward Torque".

2. Turn the dial drum fully clockwise
3. Fit the cord in numerical order as shown below.
