固定されている。 Generally, in a tape recorder equipped with a mechanical counter mechanism, a multi-polarized ring-shaped magnet is attached to the drive pulley of the counter mechanism, and a magnetic sensor facing the magnet is arranged on a printed circuit board for the sensor. However, a method is adopted in which the rotation of the drive pulley as the tape runs is detected magnetically to detect whether or not the tape is running. The mounting of the counter mechanism and magnetic sensor in this method is specifically as shown in Fig. 1, where 1 is a counter mounting board 2.
The counter mechanism is fixed to a mounting boss 3 with screws 4, and a multi-pole magnetized ring-shaped magnet 6 is adhesively fixed to a drive pulley 5 of the counter mechanism 1 . Reference numeral 7 denotes a printed circuit board for a sensor which is fixedly attached to the mounting boss 8 of the counter mounting board 2 with screws 9. A magnetic sensor 10 is disposed on the printed circuit board 7 for the sensor so as to face the magnet 6. ing. In addition, 11
is an output terminal of the magnetic sensor 10, which is soldered to a conductive pattern (not shown) on the sensor printed circuit board 7. The counter mounting board 2 is fastened to the main mounting board 12 with screws 13.

The magnet 6 and the magnetic sensor 1 on the counter mechanism 1 side are attached to the mounting part of the counter mechanism 1 and the magnetic sensor 10.
There is no risk of variation in the mounting position of the counter mechanism 1 and the magnetic sensor 10 are mounted on the same board (i.e., the counter mechanism 1

用的価値の高いものである。 As described above, according to the counter mounting device of the present invention, a multi-pole magnetized magnet is attached to the driving pulley of the counter mechanism, and a magnetic sensor facing the magnet is arranged on the printed circuit board for the sensor, so that the tape can be moved. The tape recorder is configured to magnetically detect the accompanying rotation of a drive pulley, and the tape recorder is made of synthetic resin with a counter mounting part and a magnetic sensor mounting part set in advance on the printed circuit board for the sensor. integrally molded,
Since the counter mechanism and the magnetic sensor are mounted on the same board, that is, on the printed circuit board for the sensor, the number of assembly steps can be reduced. In addition, since the counter mounting part and the magnetic sensor mounting part are integrally molded with their positions set in advance, variations occur in the mounting positions of the magnet and magnetic sensor on the counter mechanism side that are attached to the mounting part. There is no possibility that the output from such a magnetic sensor will change, and the effect is of high practical value.
