上記のように構成された従来のフロッピーディスク駆動装置では、以下のような問題がある。
最近のフロッピーディスク駆動装置の薄型化に伴って、ドアの開閉の回動中心とフロッピーディスクの挿入時にフロッピーディスクがドアを押す位置とが近付いて来た。このため、フロッピーディスクの異常挿入により、ドアの開閉の回動中心をフロッピーディスクが押すと、ドアが変形し、ドアの回動軸が外れてしまうという不具合があった。図１１は、フロッピーディスクの異常挿入の際のドアのたわみによるドア外れの説明図である。 The conventional floppy disk drive configured as described above has the following problems.
With the recent thinning of floppy disk drive devices, the pivot center for opening and closing the door has come closer to the position where the floppy disk pushes the door when the floppy disk is inserted. For this reason, when the floppy disk pushes the rotation center of opening and closing of the door due to abnormal insertion of the floppy disk, the door is deformed and the rotation axis of the door is removed. FIG. 11 is an explanatory view of the door detachment due to the deflection of the door when the floppy disk is abnormally inserted.

この発明は上記のような問題点を解消するめになされたもので、フロッピーディスクの異常挿入によるドア外れが防止された、ドアの取付安定性の高いフロッピーディスク駆動装置を得ることを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a floppy disk drive device with high door mounting stability in which door disconnection due to abnormal insertion of a floppy disk is prevented.

請求項１〜５の発明に係るフロッピーディスク駆動装置は、フロッピーディスクの異常出入時に撓むドアに当接する第１の当接部及び第２当接部をドアの上部後側及び上部前側位置に設けたことを主要な構成としている。 In the floppy disk drive device according to the first to fifth aspects of the present invention, the first contact portion and the second contact portion that contact the door that bends when the floppy disk abnormally enters and exits are positioned at the upper rear side and upper front position of the door. The main structure is that it is provided.

この発明によれば、上記のようにフロッピーディスクの異常排出により撓むドアに当接するカバーの折曲部もしくは突起部を、ドアの前側及び後側位置に設けたことにより、ドア外れ防止およびドアの取付安定性の向上を図ることができる。 According to the present invention, as described above, the bent portion or the protruding portion of the cover that comes into contact with the door that is bent due to abnormal ejection of the floppy disk is provided at the front and rear positions of the door, thereby preventing the door from coming off and the door. The mounting stability can be improved.

実施例１．
以下、この発明の一実施例を図について説明する。図１、図２はこの発明の一実施例を示し、図１は全体の平面図、図２はドアとカバーとの作用を説明する断面図である。図において、(1)は全体のメカニズムを収納するフレーム、(6)はドア、(8)はパネル、(9)はカバー、(12)はカバーの補強板、(13)はフロッピーディスクである。 Example 1.
An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention, FIG. 1 is a plan view of the whole, and FIG. 2 is a sectional view for explaining the operation of a door and a cover. In the figure, (1) is a frame that houses the entire mechanism, (6) is a door, (8) is a panel, (9) is a cover, (12) is a cover reinforcement plate, and (13) is a floppy disk. .

この実施例では、図７に示す従来例と同様にドア(6)の左右に形成したドア軸(6-1)がフレーム(1)のドアの取り付け穴(1-2)に挿入されている。ところがフロッピーディスクの異常挿入によりドア(6)の軸心が撓み、ドア軸(6-1)が取り付け穴(1-2)より脱出するおそれがあるので、フロッピーディスクの異常挿入により撓んだドア(6)に当接するカバー(9)の折曲部(9-4)が垂設されている。折曲部はカバー(9)の代わりに補強板(12)を前方に延設し、その延設部に形成することもできる。また、ドア(6)の前部にも撓んだドア(6)に当接するカバー(9)の折曲部(9-5)が垂設されるのが好ましい。
さらに、図２に示すように、ドア(6)が回動した際、折曲部(9-4)又は(9-5)に接触するのを防止するため、ドア(6)に逃げ穴(6-2)を形成する。ドア(6)に充分な厚さがあるときは逃げ穴(6-2)の代わりにくぼみ部を設けてもよい。 In this embodiment, the door shafts (6-1) formed on the left and right sides of the door (6) are inserted into the door mounting holes (1-2) of the frame (1) as in the conventional example shown in FIG. . However, because the axis of the door (6) is bent due to abnormal insertion of the floppy disk, the door shaft (6-1) may escape from the mounting hole (1-2). The bent portion (9-4) of the cover (9) that abuts on (6) is suspended. The bent portion can be formed by extending a reinforcing plate (12) forward instead of the cover (9) and extending the reinforcing plate (12). In addition, it is preferable that a bent portion (9-5) of the cover (9) that contacts the bent door (6) is also suspended from the front portion of the door (6).
Furthermore, as shown in FIG. 2, when the door (6) is rotated, the door (6) is provided with a relief hole (in order to prevent contact with the bent portion (9-4) or (9-5)). 6-2) is formed. When the door (6) has a sufficient thickness, a recess may be provided instead of the escape hole (6-2).

次に動作について説明する。フロッピーディスクが異常挿入された時、ドア(6)の回動中心部を押しドア(6)を撓ませようとした場合、カバー(9)に形成された第１の当接部である折曲部(9-4)に当接し、ドアの変形を抑えるから軸の脱出が阻止される。また、フロッピーディスク(13)を排出する時にフロッピーディスク(13)のシャッターがドア(6)に引っ掛かり、ドア(6)を前側に変形させようとした場合は、第２の当接部である(9-5)の折曲部に当接し、ドア(6)の変形を抑える。また、フロッピーディスクの挿入が挿入口の端に行われた場合に、ドア(6)の中央部が前方に撓む場合があり、これらの変形が(9-5)の折曲部で抑えられるから、軸の脱出が阻止される。また、ドア(6)には逃げ穴(6-2)が設けられているので、ドア(6)の正常な回動が折曲部(9-4)により妨げられることがない。 Next, the operation will be described. When a floppy disk is abnormally inserted, if the door (6) is pushed and the center of rotation is pushed to bend the door (6), the first contact part formed on the cover (9) is bent. Since it abuts against the portion (9-4) and suppresses deformation of the door, it prevents the shaft from escaping. Further, when the floppy disk (13) is ejected when the shutter of the floppy disk (13) is caught by the door (6) and the door (6) is to be deformed to the front side, the second abutting portion ( Abut against the bent part of 9-5) to suppress the deformation of the door (6). In addition, when the floppy disk is inserted at the end of the insertion slot, the central part of the door (6) may be bent forward, and these deformations can be suppressed by the bent part of (9-5). Thus, escape of the shaft is prevented. Moreover, since the escape hole (6-2) is provided in the door (6), normal rotation of the door (6) is not hindered by the bent portion (9-4).

実施例２．
上記実施例１では、折曲部をカバー(9)に形成していたが、フレームに形成してもよい。すなわち、図３及び４はこの実施例を示し、図３は平面図、図４は要部側面図で、図３、４に示すように、フレーム(1)の両側上部より内方へ突出する水平部材(1-a)の前方に折曲部(1-4)(1-3)を延設することによりドア(6)の前後に折曲部を配設することができる。 Example 2
In the first embodiment, the bent portion is formed on the cover (9), but may be formed on the frame. 3 and 4 show this embodiment, FIG. 3 is a plan view, and FIG. 4 is a side view of the main part. As shown in FIGS. By extending the bent portions (1-4) and (1-3) in front of the horizontal member (1-a), the bent portions can be disposed before and after the door (6).

実施例３．
上記実施例１、２は折曲部をカバー(9)又はフレーム(1)に形成しているが、この実施例の平面図及び要部側面図を示す図５、図６に示すようにパネル(8)に一体に突起部(8-3)(8-2)をドアの前後に位置するように設けてもよい。このようにすれば突起部(8-3)(8-2)はパネル成形の際簡単に製造でき、作用効果も上記実施例１と何等変わらない。 Example 3 FIG.
In the first and second embodiments, the bent portion is formed on the cover (9) or the frame (1). As shown in FIGS. The protrusions (8-3) and (8-2) may be provided integrally with (8) so as to be positioned in front of and behind the door. In this way, the protrusions (8-3) and (8-2) can be easily manufactured at the time of panel molding, and the operational effects are not different from those of the first embodiment.
