この考案はコンピユータやワードプロセツサの
記録再生装置として用いられるフロツピデイスク
のドライブ装置に関するものである。[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a floppy disk drive device used as a recording and reproducing device for computers and word processors.
フロツピデイスク・ドライブ装置にフロツピデ
イスクを挿入すると、回転駆動体と係合させる
為、自動的に降下せしめると共に、磁気ヘツドを
フロツピデイスクに適度の圧力で圧接せしめるも
のがある。
When a floppy disk is inserted into a floppy disk drive device, the floppy disk is automatically lowered to engage the rotating drive, and the magnetic head is pressed against the floppy disk with a moderate pressure.
第１図及び第２図はその一例を示すもので、フ
ロツピデイスクを収容したカセツトＡを矢印方向

パ２ａとスライダ３のロツク装置（図示せず）を
押し、ヘツドホルダ２を前進（第２図では右方に
移動させる）させると共にロツク装置のフツクを
外し、スライダ３を釈放する。 FIGS. 1 and 2 show an example of this. When a cassette A containing a floppy disk is inserted in the direction of the arrow, the front edge 1 pushes the stopper 2a of the head holder 2 and the locking device (not shown) of the slider 3. , the head holder 2 is moved forward (moved to the right in FIG. 2), the locking device is unhooked, and the slider 3 is released.
釈放されたスライダ３はバネ４によつて牽引さ
れ、スライダ３に設けた扛上カム３ａ，３ａが第
２図において左方に移動する。 The released slider 3 is pulled by the spring 4, and the lifting cams 3a, 3a provided on the slider 3 move to the left in FIG.
この時、ヘツドホルダ２の側面に設けた突起
５，５（図示のものはベアリングが取付けられて
いる）は、器枠６の側板７に設けた型案内溝
８，８の縦溝部の上部に位置しているので、スラ
イダ３が左方に移動すると、バネ９によつて牽引
されてカセツトＡと共に降下する。 At this time, the protrusions 5, 5 provided on the side surfaces of the head holder 2 (the one shown has bearings attached) are positioned above the vertical grooves of the mold guide grooves 8, 8 provided in the side plate 7 of the container frame 6. Therefore, when the slider 3 moves to the left, it is pulled by the spring 9 and descends together with the cassette A.
なおヘツドホルダ２の両側はコ字状に屈曲され
ていて、カセツトＡの挿入を案内すると共に、屈
曲部はカセツト保持の役目をしている。 Both sides of the head holder 2 are bent in a U-shape to guide the insertion of the cassette A, and the bent portions serve to hold the cassette.
上記カセツトＡの降下により突起１０を介して
持ち上げられていたヘツドアーム１１は図示しな
いバネによつて降下し、磁気ヘツドはフロピデイ
スクの記録面に圧接される。 As the cassette A descends, the head arm 11, which had been lifted up via the protrusion 10, is lowered by a spring (not shown), and the magnetic head is brought into pressure contact with the recording surface of the floppy disk.
そして、次に取出しキー１２をバネ４に抗して
押すと、スライダ３が前進した位置で前記図示し
ないロツク装置のフツクによつてロツクされると
共に、スライダ３の扛上カム３ａ，３ａが型案
内溝８，８の縦溝部内の突起５，５を上昇させ、
突起５，５が横溝部の端部に達すると、ヘツドホ
ルダ２はバネ９によつて後方に牽引され、第２図
に示す位置に戻る。 Then, when the take-out key 12 is pushed against the spring 4, the slider 3 is locked in the advanced position by the hook of the locking device (not shown), and the lifting cams 3a, 3a of the slider 3 are locked into the mold. Raise the protrusions 5, 5 in the longitudinal grooves of the guide grooves 8, 8,
When the projections 5, 5 reach the ends of the transverse grooves, the head holder 2 is pulled rearward by the spring 9 and returns to the position shown in FIG.
以上のように従来のフロツピデイスク・ドライ

ネ９によつてヘツドホルダ２が急激に降下して、
それにより扛上せしめられていたヘツドアーム１
１は図示しない弾圧バネによつて急激に降下する
ため、磁気ヘツドがフロツピデイスクの記録面に
衝突して損傷せしめ、寿命を短かくするという欠
点があつた。 As described above, in the conventional floppy disk drive device, when loading, that is, when inserting a cassette, the head holder 2 is suddenly lowered by the spring 9.
Head arm 1 was lifted as a result.
1 is rapidly lowered by a compression spring (not shown), which has the disadvantage that the magnetic head collides with the recording surface of the floppy disk, damaging it and shortening its life.
この考案は上記の欠点を解決するためになされ
たもので、スライダ減速用のダンパ装置を設けて
ヘツドアーム１１の降下速度を遅くして衝撃力を
小さくするようにしたものである。
This invention was made to solve the above-mentioned drawbacks, and a damper device for decelerating the slider is provided to slow down the descending speed of the head arm 11 and reduce the impact force.
即ち、この考案は器枠にロータリ式ダンパ装置
を設け、その回転軸に設けたレバーを前記スライ
ダと連繋せしめたものである。 That is, in this invention, a rotary damper device is provided in the container frame, and a lever provided on the rotary shaft of the rotary damper device is connected to the slider.
以下この考案の実施例を図面に基づき説明すれ
ば次の通りである。
Embodiments of this invention will be described below based on the drawings.
第３図はこの考案の実施例の拡大斜視図を示す
もので、器枠６にロータリ式オイルダンパ装置１

設したピン１４と係合する２叉レバー１５を設け
たものである。 FIG. 3 shows an enlarged perspective view of an embodiment of this invention, in which a rotary oil damper device 1 is mounted on a container frame 6.
3 is fixed, and a two-pronged lever 15 that engages with a pin 14 protruding from the slider 3 is provided on its rotating shaft 13a.
この構造によると、カセツトＡを押し込んで、
ロツク装置のフツクが外された時、スライダ３は
バネ４によつて牽引されるがダンパ装置１３によ
つて移動速度が緩和され、従つて扛上カム３ａを
ゆつくりと移動するので、バネ９によるヘツドホ
ルダ２の落下速度もゆつくりとなり、ヘツドアー
ム１１に取付けられた磁気ヘツドの衝撃力も弱く
なり、フロツピデイスクの損傷を激減させる効果
がある。 According to this structure, when cassette A is pushed in,
When the hook of the locking device is released, the slider 3 is pulled by the spring 4, but the moving speed is moderated by the damper device 13. Therefore, the lifting cam 3a is moved slowly, so that the slider 3 is pulled by the spring 4. The falling speed of the head holder 2 is also slowed down, and the impact force of the magnetic head attached to the head arm 11 is also weakened, which has the effect of drastically reducing damage to the floppy disk.
