。BACKGROUND ART FIG. 3 is a plan view showing a conventional example, in which a stamping motor is used as the drive motor 1.
A lead screw 2 is formed on the rotating shaft of the lead screw 2, and a needle 3 is engaged with a thread groove of the lead screw 2. The other side of the needle 3 is fixed to a carriage 4 on which a magnetic head 6 is installed, and this carriage 4 is supported by a sliding rod 6 so as to be slidable in a linear direction.

気ヘッド６を所定の場所へ移動させることが出来る。Next, the operation will be explained. As the drive motor 1 rotates forward and backward, the thread groove of the lead screw 2 moves in the direction of the arrow 7, and the carriage 4 also moves through the needle 3, as indicated by the arrow 7.
It moves along the sliding rod 6 in the direction of. In this way, the magnetic head 6 can be moved to a predetermined location.
発明が解決しようとする問題点

モータ１の駆動負荷になってキャリッジ４の移動距離に
偏差を生じるという問題があった。Problems to be Solved by the Invention Although the conventional device is constructed as described above, the carriage 4 is tilted due to the gap between the insertion hole of the sliding rod 6 provided in the carriage 4 and the sliding rod 6. As a result, the positioning accuracy of the head deteriorates, and the sliding force with the sliding rod 6 becomes a driving load on the drive motor 1, causing a deviation in the moving distance of the carriage 4.
この発明は以上の問題点を改善するためになされたもの
である。This invention has been made to improve the above problems.
問題点を解決するだめの手段

したものである。Means for Solving the Problems and the present invention achieves the above object by engaging one side of the carriage of the floppy disk head with a drive mechanism, and the other side contacting the base via a rolling sphere. It is structured as follows.
作用
以上の構成とすればキャリッジは球体を介して基体と接
するので上記従来の隙間によるキャリッジの頌き等はお
きないものとなり、また駆動負荷にもならないとなる。If the configuration is more efficient, the carriage will come into contact with the base body through the sphere, so the carriage will not sag due to the above-mentioned conventional gap, and will not become a driving load.

１２に対してほぼ均等の予圧がかけられている。Embodiment FIGS. 1 and 2 show an embodiment of the present invention. In the figures, the base body 8 has two U-shaped protrusions 9 and 10.
A corner portion 16 is formed on the other side of the gear f and gear 4. A sphere 11 is placed between the base body 8 and the carriage 4.
．． 12 is arranged, and the carriage 4 is preloaded by an elastic body 14 attached to the base body 8 via another sphere 13. This preload portion consists of the two spheres 11.
A substantially equal preload is applied to 12.

リッジ４へ伝達している。A round bar 3' is provided on one side of the carriage 4 and engages with the lead screw 2 of the stepping motor 1, which is arranged parallel to the direction in which the carriage 4 moves. The rotational motion of the stepping motor 1' is transmitted to the carriage 4 as a linear motion.

達することが出来るものとなる。Effects of the Invention As described above, this invention changes the support of the head carriage from the conventional sliding movement to the rolling movement of spheres, so the carriage does not tilt, and furthermore, even if preload is applied, the sliding force does not increase. The movement of the motor can be accurately transmitted to the carriage under light loads.
