Technical Information

Hall IC (Integrated Circuit)

This recorder is adopted with the full automatic stop mechanism. When the tane is finished in any mode: record. playback, fast forward or rewind, the tape transporting mechanism stops and the corresponding control buttons return to their normal positions and the power is shut off. The tape stop is detected by the Hall IC 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 tane is running

HALL ELEMENT

The Hall IC consists of the Hall element and amplifier as shown in Fig. 2.

The Hall element is one of magneto-electronic converter and possesses the Hall effect.

The Hall IC acts as an electronic switch which makes or brakes a circuit according to the magnetic strength.

As the electronic switch does not have any contact, it provides the longer serviceable life and the higher reliability than mechanical switches e.g. reed switches.

HALL EFFECT

When a conductor or semiconductor carrying a current is placed in a magnetic field as shown in Fig. 4, the output voltage is expressed by

VH = RH [lc x B/t]

where But is a parameter called the Hall coefficient.

Ic is the control current B is the magnetic field strength. t is the thickness of the element.

CIRCUITRY OF TAPE STOP DETECTOR

1. While the tape is running

1) The voltage wave mode as shown in Fig. 6 appears on the output terminal of the Hall IC.

2) The wave (Fig. 6) is amplified by the transistor X105 and the bias voltage as shown in Fig. 7 is applied to the X106

The X106 becomes ON state, and the voltage across the collector and emitter of X106 decreases to cut off the X107.

3) The collector current of X107 does not flow so that the solenoid does not function.

2. When the tape stops

  • 1) The output of the IC maintains constant voltage (DC) according to the magnetic field strength.
  • 2) The DC voltage is choked by the capacitor C184.
  • 3) The bias voltage does not change so that the X106 maintains the OFF state.
  • 4) The voltage across the collector and emitter of X106 drives the X107 to become the ON state, and the collector current flows. The solenoid functions to stop the mechanism.

3. When the PAUSE switch is pressed

When the PAUSE switch is turned on, the bias voltage is applied to the X106 and the X106 becomes the ON state. The following responses are the same as "While the tape is running".

Adjustment of Cassette Mechanism

Auto Stop Mechanism

  • If the auto stop mechanism is defective, check as follows.
  • 1. When the solenoid does not suck the plunger:
    • a. The coil of the solenoid may be opencircuited. The resistance value of solenoid should be approximately 50Ω.
    • b. The diode (D113) may be open- or shortcircuited.
    • c. The transistors (X105~107) may be defective.
    • d. The connecting wires may be opencircuited.
    • e. If the solenoid is lack of suction ability, bend the part A of adjusting arm to the B direction as shown in Fig. 23.
  • 2. When the auto stop mechanism does not function, though the solenoid has sucked the plunger.
    • a. The motor may be lack of torque. If it is, change it.
    • b. The capstan belt may be lack of tension. If it is, change it.
    • c. FF and rewind torque may be extremely high. If it is, adjust as following the "Adjustment of FF & Rewind Torque".
    • d. The auto lever may be deformed. If it is, change it.

Fig. 23

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.

Fig. 25

Thrust of Flywheel

The clearance between the top of flywheel shaft and the flywheel bracket should be within 0.2 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.

Page 9
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 reek 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. 25.
    • If the tape is fast forwarded at the beginning of cue action, bend the part (C) to the B direction as shown in Fig. 25.

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.
    • 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. 25.
    • 2) If the tape is fast forwarded at the beginning of review action, bend the part (C) to the B direction as shown in Fig. 25.
    • 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 (A) of pinch roller arm plate as shown in Fig. 27.

Fig. 26

Location of Heads

The record/play and erasing heads should be positioned as shown below.

Fig. 28

Gap between Record Safety Lever and Record Slide Lever

  • 1. The gap between the record safety lever and the record slide lever should be within 0.5 to 0.8mm.
  • If the gap is out of limits, adjust it by bending the part (A) of record slide lever.
    • Note: If the gap length exceeds 0.8mm, the recording circuit may be energize and the recorded signals may be erased when the REC button has happened to be pressed.

Fig. 29

Page 10

Playback Torque

  • 1. The playback torque should be within 40 to 70g-cm.
  • If the torque is less than 40g-cm, set the clutch spring to the 3 position. If it exceeds 70g-cm, set the clutch spring to the 1 position.
    • Note: Before adjusting the torque wipe off the surface of rubber parts and rotating parts, if the torque is not sufficient.

Fig. 30

Adjustment of F.F. & Rewind Torque

1. Fast Forward Torque

In the fast forward mode, check that the F.F. torque is within 60 to 150g-cm by applying the torque gauge to the take-up reel disk.

  • a. If the torque is less than 60g-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 clockwise (4→3→2→1) to obtain the proper torque.
  • b. If the torque is over 150g-cm, turn the clutch spring plate counterclockwise (1→2→3→4) to obtain the proper torque.

2. Rewind Torque

In the rewind mode, check that the rewind torque is within 60 to 150g-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".

Fig. 31

Memory Facility

If the Memory facility is defective, treat as follows.

  • a. If the switch assembled in the tape counter is defective, change the counter.
  • b. If the counter does not turn:
    • Check the counter belt. If it is defective, change it. Change the counter, if it is defective.
  • c. The memory switch mounted on the counter may be defective in contact. If it is change the switch.
  • d. The connecting wires may be open circuited.
  • e. The auto stop mechanism may be defective. Refer to the "Auto Stop Mechanism".
