接される。 The mounting board 16 has a screw 19 connected to the through hole 14, a substantially cylindrical spacer 20, and a head board 21.
The screw 24 is inserted through the through hole 22 of the head board 21 and tightened with the nut 23, and the screw 24 is inserted through the notch 15, the coiled spring 25, and the through hole 26 of the head board 21 and screwed into the nut 27. It is fixed to the head substrate 21. This head board 2
Reference numeral 1 is arranged in parallel on the main chassis (not shown) of the tape recorder, and slides on the main chassis in the direction of arrow A as shown in FIG. 3 in conjunction with the operation of a playback operator (not shown). At this time, the tape contacting surface 12 of the recording/reproducing head 11 is inserted into the head insertion hole 29 of the cassette half 28 shown by the dashed line in the figure, and is brought into contact with the tape 30 with a predetermined pressure.

ができるようになつている。 Also, as shown in FIG. 2, the mounting board 16 is again urged upward in the figure by the spring 25, and by turning the screw 24 appropriately, the mounting board 16 is held between the screw 19 and the spacer 20. It can be minutely rotated in the directions of arrows B and C in the figure using the portion as a fulcrum, so that so-called azimuth adjustment for adjusting the inclination of the recording/reproducing head 11 with respect to the tape 30 can be performed.

ツド１１の自由度を十分とることができないから
である。 As is well known in cassette tape recorders, the insertion distance l of the recording/reproducing head 11 into the cassette half 28 is standardized as shown in FIG. 16
This is done so that it does not extend. This is the third
As shown in the figure, the space d1 between the lower surface of the recording/playback head 11 in the figure and the cassette half 28 is widened so that the cassette half 28 can be adjusted when adjusting the azimuth.
This is to increase the degree of freedom of the recording/reproducing head 11 within the recording/reproducing head 11. That is, if the mounting board 16 extends to within the above-mentioned insertion distance l of the lower surface of the recording/playback head 11 in the figure, as shown by the dotted line in FIG. This is because the space d2 with respect to the cassette half 28 becomes narrower, and the recording/reproducing head 11 cannot have a sufficient degree of freedom within the cassette half 28 during azimuth adjustment.

短くすることによつて小型化を図るようにする必
要がある。 Incidentally, in recent years, there has been a trend for tape recorders to be more mobile, such as being small, lightweight, and convenient to carry, as exemplified by microcassette tape recorders. Of course, a small one is required. When miniaturizing the recording/reproducing head in this way, since the insertion distance l of the recording/reproducing head into the cassette half is standardized as described above, this distance l must be ensured. Therefore, when downsizing, it is necessary to reduce the size of the recording/reproducing head 11 by shortening the rear end of the recording head 11, as shown by the two-dot chain line in FIG.

た。 However, if the rear end of the recording/playing head 11 is shortened, the recording/playing head 11 and the mounting board 16
There was a problem in that the adhesion area between the recording and reproducing head 11 could not be firmly fixed to the mounting substrate 16 due to the reduced adhesive area. Furthermore, if the mounting board 16 is extended to within the insertion distance l of the recording/playback head 11 in order to increase the bonding area, it will be possible to extend the mounting board 16 within the insertion distance l of the recording/playback head 11. When adjusting the azimuth, there was a grudge that the recording/playback head 11 did not have enough flexibility. Furthermore, since the mounting board 16 and tape guide member 18 are provided separately, they can be attached to the recording/playback head 1.
There was also the problem that the work of pasting it on 1 was complicated.
