【発明の詳細な説明】 産業上の利用分野 本発明は、磁気テープのトラック位置切換えを磁気ヘッドの回転で行なう往復録音再生可能なテープレコーダの磁気の配線装置に関する。 FIELD OF THE DETAILED DESCRIPTION OF THE INVENTION Industry The present invention relates to a magnetic wire device of the reciprocating recording reproducible tape recorder to perform track position switching of the magnetic tape by the rotation of the magnetic head.

従来の技術 最近、磁気ヘッドを回転させて磁気テープのトラック位置の切換えを行なう往復録音再生可能なテープレコーダが提案され、特にカセット式テープレコーダにおいては磁気テープ走行の負荷軽減によるワウ・フラッタの向上、及び機械的精度を向上させる点に着眼され、主流となっている。 Description of the Related Art Recently, reciprocating recording reproducible tape recorder is proposed that rotates the magnetic head for switching the track position of the magnetic tape, in particular the improvement of wow and flutter due to unloading of the magnetic tape running in cassette tape recorders , and is focusing on the point of improving the mechanical precision, it has become mainstream.

従来この種の装置においては、磁気ヘッドの信号を伝送するリード線を回転軸の中空部を挿通させて背面外部に引出すか、もしくはリード線を回転軸あるいはヘッドと共に回転する回転部材に巻付けて側面外部へ引出すかのリード線処理を行なう方法が知られている。 In this type of conventional device is wound to the rotating member to rotate either the lead line for transmitting a signal of the magnetic head is inserted through the hollow portion of the rotary shaft draw the back outside, or a lead wire together with the rotating shaft or the head how do the performing the lead processing draw the side surface outside is known.

しかしながら、リード線の断線や捩り抵抗による回転負荷、又、半田付部の信頼性の低さ等、非常に多くの課題を有していた。 However, the rotation load due to disconnection or torsional resistance of the lead, also unreliable soldering portion or the like, and had a great many problems. このため、近年、リード線をフレキシブルプリント基板(以下FPCという)に置き換えた回転ヘッドが考案されていた。 Therefore, in recent years, the rotary head has been devised which is replaced leads to a flexible printed circuit board (hereinafter referred to as FPC).

以下図面を参照しながら上述したテープレコーダの磁気ヘッド装置について説明する。 The magnetic head device of the tape recorder described above with reference to the drawings will be described.

第3図と第4図はFPCを用いた従来例であり、第3図は分解斜視図であり、第4図は背面から見た部分断面図である。 Figure 3 and Figure 4 is a conventional example using the FPC, Fig. 3 is an exploded perspective view, FIG. 4 is a partial sectional view, as viewed from the rear. 回転ヘッド20を収納固定したヘッドマウント21 Head mount 21 that accommodates fixed rotary head 20
は他端にヘッド回転切換ギア18aを形成された回転体22 Rotating body 22 is formed a head rotation changeover gear 18a on the other end

作用 本発明は上記のように、回転ヘッド配線用のFPCの磁気ヘッド半田付部近傍に、巻付け方向と反対側に突型形状を追加することにより、部品点数やコストを上げることなく、回転操作に対する信号線としての寿命が長く、 Action The present invention as described above, the magnetic head near the soldering portion of the FPC of the rotary head wires, by adding 突型 shape on the side opposite to the winding direction, without increasing the number of parts and the cost, the rotation life of the signal line for the operation is long,
高信頼性の回転ヘッド配線装置を実現したものである。 It is obtained by realizing the rotary head interconnect device of high reliability.

実 施 例 以下、本発明の実施例を図面に基づいて説明する。 Implementation example will be described below with reference to embodiments of the present invention with reference to the drawings.

第1図は分解斜視図であり、第2図は背面から見た部分断面図である。 Figure 1 is an exploded perspective view, FIG. 2 is a partial cross-sectional view seen from the back.

第1図〜第3図において、回転ヘッド20を収納固定したヘッドマウント21は、他端にヘッド回転切換ギア22を形成された回転体23に取付ビス24で固定され、ベースプレート25上に設けられた軸26に軸支されており、上記ベースプレートはヘッドベース27に固定され、ヘッドベースは再生時に前進するヘッド基板(図示せず)に取付けられている。 In Figure 1-Figure 3, a head-mounted 21 accommodating fixing the rotary head 20 is secured by mounting screws 24 to the rotating body 23 to the head rotation switching gear 22 formed at the other end, is provided on the base plate 25 are supported by a shaft 26, the base plate is fixed to the head base 27, the head base is mounted on the head substrate advances at the time of reproduction (not shown). また上記ヘッド回転切換ギア22は駆動ギア Also the head rotary switch gear 22 is drive gear
28と噛合しており、この駆動ギア28はヘッドベース上の支軸27aに回動自在に軸支されている。 28 and meshes with this driving gear 28 is rotatably supported on a support shaft 27a on the head base.

さらにヘッド20に接続されたFPC29はヘッドマウント2 FPC29 which is further connected to the head 20 is a head-mount 2
1の出口で90度曲げられ、回転体23の開口部23aを通され、FPCの巻付部29aを回転体23のドラム部23bに180度の回転に必要な余裕を持って巻付けられている。 Bent 90 degrees first outlet, is passed through the opening 23a of the rotating body 23, wound with a margin required for the rotation of 180 degrees the winding portion 29a of the FPC to the drum portion 23b of the rotary member 23 there. ヘッドマウント21からの出口でFPC29は巻付部29aと反対側に突型形状部29cを備えており、巻き付けられている状態で巻付部29aの内側は突型形状部29c表面を押圧している。 FPC29 at the outlet from the head mount 21 includes a 突型 shaped portion 29c on the side opposite to the Makizuke portion 29a, the inner side of the winding portion 29a is in a state of being wound by pressing the 突型 shaped portion 29c surface there. さらにFPC端部29bをヘッドベース27に固定する構成となっている。 Further it is configured to fix the FPC end portion 29b to the head base 27.

また、FPC端部固定は、このヘッドブロック内ではなく、メカシャーシ等に行なっても良い。 Further, FPC ends fixed, rather than the head block may be performed on the mechanical chassis or the like.

以上のように構成された本実施例について以下その動作を説明する。 The operation will be described below the present embodiment constructed as described above.

第2図において初期状態はFPC29の弾性により(イ) Initial state by the elasticity of FPC29 at a second view (b)
の位置をとる駆動ギア28は、ヘッド切換駆動手段(図示せず)により、(ロ)の位置まで回動し、それと連動し回転体23はPFC29を巻込みながら180度回転し、第2図の位置となり、この時ヘッドのトラックは回転中心に対し点対称位置に回転し、正転状態から反転状態のトラック位置となる。 The driving gear 28 to take the position, the head switching drive means (not shown), rotates to a position (B), Interlocked with this rotating member 23 is rotated 180 degrees while winding the PFC29, Figure 2 It becomes position, the track at this time the head is rotated to a point symmetrical positions with respect to the rotation center, a positive rotation state track position of the inverted state.

以上のように本実施例の様に、FPCに突起29cを設けることにより、FPCの巻付部は第4図19cの如くFPC端面とは接触せず、突型形状部29c表面と接触するため、回転回数が増えても、巻付部29a内側は摩耗しない。 As in the present embodiment as described above, by providing the protrusions 29c on the FPC, the winding portion of the FPC is not in contact with the FPC end face as in FIG. 4 19c, for making contact with 突型 shaped portion 29c surface , even increased number of rotations, the winding portion 29a inside is not worn. 又、FPC In addition, FPC
29のヘッドマウント21からの出口では、FPC巻付部29a方向にヘッド20の回転に伴い応力を受けるが、同時に、突型形状部29cにも、巻付部29a内側から応力を受けるため、前記出口部では、捩り応力がかからないため、FPC2 At the outlet from the head mount 21 of 29, but stressed with the rotation of the head 20 to the FPC winding portion 29a direction, at the same time, also 突型 shaped portion 29c, for receiving the stress from the inner winding section 29a, the since the outlet portion, which does not take torsional stress, FPC2
9及び、ヘッド端子への半田付部の寿命を長くすることができる。 9 and it can increase the life of the soldered portion to the head terminal.

発明の効果 以上のように本発明は、正転方向,反転方向の各々のテープ走行方向に応じて回転自在に構成された磁気ヘッドとこの磁気ヘッドと共に回転する回転部材と、磁気ヘッドに接続され、この回転部材に回転方向の弾力を有して巻付けられたFPCとを具備し、前記フレキシブル基板の磁気ヘッド半田付部近傍に巻付け方向と反対側に突型形状を備え、この突型形状部の表面に前記巻付けられたフレキシブルプリント基板が接触し、当該突型形状部を押圧するように構成したことにより、フレキシブル基板の巻付け部が突型形状部の表面と接触するため、回転回数が増えてもフレキシブル基板の巻付部の内側は摩耗することがなく、フレキシブル基板のヘッドマウントからの出口では突型形状部にフレキシブル基板巻付部内側から応力を受 The present invention as described above the effect of the invention, a rotary member which rotates forward direction, the rotatable constructed magnetic head in accordance with the tape running direction of each of the inverted direction with the magnetic head is connected to the magnetic head this has the firmness of the rotation direction to the rotary member and a FPC wound around, equipped with 突型 shape and winding direction opposite to the magnetic head near the soldering portion of the flexible substrate, the 突型shaped section and the wound flexible printed circuit board comes into contact with the surface of the, by constructing so as to press the 突型 shaped portion, since the winding portion of the flexible substrate is in contact with the surface of the 突型 shaped portion, inner winding portion of the flexible substrate is also increasingly rotation number without having to wear, receiving the stress from the inner portion with the flexible substrate around the 突型 shaped portion at the outlet from the head-mounted flexible substrate けるため、当該出口部では捩り応力がかかることなく、フレキシブル基板及びヘッド端子の半田付部の寿命を長くすることができるものである。 Kicking Therefore, without torsional stress according to in the outlet portion, in which it is possible to lengthen the life of the soldering portion of the flexible board and the head terminal. これにより、部品点数,コストを上げずに、回転操作に対する寿命が非常に長い回転ヘッド用配線装置を実現できるものである。 Thus, the number of parts, without increasing the cost, life for rotating operation is one that can achieve a wiring apparatus for a very long rotary head.
