ディ スク ドライ ブ装置にセ ッ ト された際にはデータアクセスのた めにディ スク表面とディ スク ドラ イ ブ装置の磁気へッ ドは接触させ る必要があるため、 プロテクタには開口部が設けられている。  When set in a disk drive, the protector has an opening because the disk surface and the magnetic head of the disk drive must be in contact for data access. Is provided.
開口部を開放したままにしてお く とディ スク表面を傷つけるおそ れが有るためデイ スク ドライ ブ装置にセ ッ ト された際に開口部を露 出させる シ ャ ッタが設けられている。  If the opening is left open, the disk surface may be damaged, so a shutter is provided to expose the opening when it is set in the disk drive.
例えば同じ 3. 5 イ ンチディ スクの場合、 記憶密度 · 容量等で差異 が有るため、 ディ スク毎にその識別を表示しな く てはならない。 従 つて、 識別を表示する場合、 プロテクタ本体又はシャ ツタに表示す るという こ とになる力 <、 コス トを考えた場合、 シ ャ ツタに識別を表 示した方が安く 済むため、 シャ ツタを形成した後スク リ ーン印刷又 はパッ ト印刷で識別を付している。  For example, in the case of the same 3.5-inch disc, there is a difference in storage density, capacity, etc., so the discrimination must be displayed for each disc. Therefore, when displaying the identification, the force to display it on the protector body or the shutter <<Considering the cost, it is cheaper to display the identification on the shutter, so the shutter After forming, identification is given by screen printing or pad printing.
しかしながら、 シャ ツタにスク リ ーン印刷又はパッ ト印刷を施す 場合、 シ ャ ツタの変形を防止するため当板等を嵌挿しな く てはなら ないため、 工程数の増加と共に作業性を悪く し、 その結果、 シャ ッ タの製造コス 卜が高く なる という課題が有る。  However, when screen printing or pad printing is performed on the shutter, this plate must be inserted to prevent deformation of the shutter. As a result, there is a problem that the manufacturing cost of the shutter increases.
また、 シ ャ ツタを合成樹脂で作った場合、 前記当板等の嵌揷工程 が必要となると共に、 特にァセタール系樹脂で作ると当該樹脂ば揆 油生を有するため印刷のイ ンクの乗りが悪いため、 シャ ツタの印刷 面を荒らす表面処理を施す必要が有り、 多く の工程が必要となる。 表面を荒らす処理はレーザ加工で行うが、 シャッタは肉薄に形成さ れるため加工中に損傷し易く不経済であるという課題も有る。 In addition, when the shutter is made of a synthetic resin, the fitting process of the above-mentioned plate or the like is performed. In particular, if the acetal resin is used, it is difficult to ride ink on the print because of the oiliness of the resin, so it is necessary to apply a surface treatment to roughen the print surface of the shutter. Is required. Although the surface roughening process is performed by laser processing, there is also a problem that the shutter is easily formed and is uneconomical due to its thin thickness, which is easily damaged during processing.
さらに、 合成樹脂でシャ ツタを作る場合、 表面の凹凸で文字、 記 号等を形成する方式も提案されたがシャ ツタは肉薄であるため実現 に至っていない。 発明の開示  Furthermore, when a shutter is made of a synthetic resin, a method of forming characters, symbols, and the like with irregularities on the surface has been proposed, but this has not been realized because the shutter is thin.
