【考案の詳細な説明】
本考案は、テープレコーダーにおける磁気ヘッドの取付
装置、詳しくは小型テープレコーダーにおける磁気ヘッ
ドの取付装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic head mounting device for a tape recorder, and more particularly to a magnetic head mounting device for a small tape recorder.
テープレコーダーにおける磁気ヘッドは、テープレコー
ダーの心臓部の一つであり、テープレコーダー内に配設
された磁気ヘッドは、そのヘッド面を正しくテープに密
接させるために、取付位置の調整が行なわれる。The magnetic head in a tape recorder is one of the core parts of the tape recorder, and the mounting position of the magnetic head disposed in the tape recorder is adjusted in order to properly bring the head surface into close contact with the tape.
この調整は、テープに対スるヘッドの高さ調整、接触調
整、アジマス調整および回動調整等を正確に行なうので
あるが、このうち高さの調整は、ディスタンスピースを
用いたり、または調整ねじを設け、そのねじ込み量を調
節することによって行なわれる。This adjustment involves accurately adjusting the height of the head relative to the tape, contact adjustment, azimuth adjustment, rotation adjustment, etc. Of these, height adjustment is performed using a distance piece or with an adjustment screw. This is done by adjusting the screw-in amount.
しかし、これ等はすべてヘッドの取り付けであるヘッド
取付板、又はその支持板の上面で行なわれるので、ヘッ
ドを取り付ける個所の高さにはかなりのゆとりを設ける
必要があり、従って、小型テープレコーダーにおいては
、特にその厚みが増して薄型にすることが困難になる欠
点がある。However, all of this is done on the top of the head mounting plate or its support plate, which is where the head is mounted, so it is necessary to provide a considerable amount of clearance in the height of the place where the head is mounted. has the disadvantage that its thickness increases, making it difficult to make it thin.
本考案の目的は、上記の欠点を除くため、磁気ヘッドの
取り付けられたヘッド取付板を載置するヘッド支持板に
切欠部を設げ、この切欠部に磁気ヘッド取付板が上方か
ら入り込めるようにしたテープレコーダーにおける磁気
ヘッドの取付装置を提供するにある。The purpose of this invention is to eliminate the above-mentioned drawbacks by providing a notch in the head support plate on which the head mounting plate with the magnetic head attached is placed, so that the magnetic head mounting plate can fit into this notch from above. The present invention provides a magnetic head mounting device for a tape recorder.
本案によれば、磁気ヘッド取付板が切欠部に入りこむた
め、磁気ヘッドの高さの調整およびアジマス調整を行な
うとき、ヘッドの高さ位置の調節の上下範囲が節約され
、それだけテープレコーダーの厚みを薄くすることが出
来る効果が得られる。According to the present invention, since the magnetic head mounting plate fits into the notch, when adjusting the height and azimuth of the magnetic head, the vertical range of adjusting the height position of the head can be saved, and the thickness of the tape recorder can be reduced accordingly. The effect of making it thinner can be obtained.
