に挿入される。Referring to FIGS. 1 and 2, the housing 1 of, for example, an optical disk cartridge C 1 of the present invention has an upper half piece 2 similar to a conventional cartridge.
And the lower half piece 3 are formed so as to match with each other, and a rotation hole (not shown) is formed in the center of the housing 1. A shutter 6 is opened and closed in the left and right direction to open and close the rotation hole and the head insertion hole 5. Slider is possible. A head 13 which is the center of bending of the shutter 6 is fixed to the upper surface of a slider 14 which slides on a guide rail 22 of a guide portion formed at the end of the housing 1 on the writing / reading device side. A torsion coil spring 10 is housed on the left side of the housing 1 in the drawing, and one end 10a of the torsion coil spring 10 engages with an end portion of a slider 14 so that the shutter 6 can rotate through the slider 14 and a head. It is biased to close the insertion hole 5. Further, a cutout opening 27 is provided at the end of the head 13 of the shutter 6, and an opening / closing pin P held at the tip of a drive arm 30 provided on the drive section side of the recording / reproducing apparatus through this opening 27. 1 is
It is inserted into a receiving hole 29 formed on the slider corresponding to the opening 27.
シャッタ６の頭部13はネジ止め、融着等の適宜な手段に
よって開口27および受穴29の位置関係が下記の如くなる
ように固着せしめられている。The head 13 of the shutter 6 is fixed by appropriate means such as screwing or fusion so that the positional relationship between the opening 27 and the receiving hole 29 is as follows.
すなわち、第１図、第２図の如く受穴29の開閉ピンP1が
スライダ14を押動させる押動側の側面F2が開口27の対応
する切欠押動面F1より開閉ピンP1がスライダ14を押動さ
せる方向とは逆方向に突き出し状態で両者は一体化され
ている。すなわち、前記開口27の押動側の端面F1は受穴
29の入口より引っ込んだ位置にある。このように形成す
ることによって前記開閉ピンP1は自由に開口27および29
に対して第２図に示す如く係脱することができる。That is, as shown in FIGS. 1 and 2, the opening / closing pin P 1 of the receiving hole 29 pushes the slider 14 and the side surface F 2 on the pushing side is closer to the opening / closing pin P 1 than the corresponding notch pushing surface F 1 of the opening 27. The two are integrated in a state of protruding in a direction opposite to the direction in which the slider 14 is pushed. That is, the pushing-side end face F 1 of the opening 27 is a receiving hole.
It is in a position retracted from the entrance of 29. By forming in this way, the opening / closing pin P 1 is freely opened.
On the other hand, it can be disengaged as shown in FIG.
尚、前記スライダ14の先端には傾斜面14aが形成され、
この傾斜面14aにより他方の駆動アーム31に取付けられ
た開閉ピンP2がスムースにスライダの先端およびシャッ
タの頭部13上を通過できるようになっている。An inclined surface 14a is formed at the tip of the slider 14,
The inclined surface 14a allows the opening / closing pin P 2 attached to the other drive arm 31 to smoothly pass over the tip of the slider and the head 13 of the shutter.
このように、記録再生装置側の開閉ピンP1と係合するス
ライダの受穴29の開閉ピンP1の押動側面F2をこれに対応
するシャッタ６の開口27の切欠面F1より開閉ピンP1がシ
ャッタ６を押動させる方向とは逆方向に突き出すように
形成することにより、前記開閉ピンと前記開口および受
穴との係脱がスムースに行われ、シッャタの開閉が迅速
かつ円滑に行われるという効果を奏する。In this way, the pushing side surface F 2 of the opening / closing pin P 1 of the receiving hole 29 of the slider that engages with the opening / closing pin P 1 of the recording / reproducing device is opened / closed from the corresponding notched surface F 1 of the opening 27 of the shutter 6. By forming the pin P 1 so as to project in the direction opposite to the direction in which the shutter 6 is pushed, the opening / closing pin is smoothly engaged with and disengaged from the opening and the receiving hole, and the shutter is opened and closed quickly and smoothly. Has the effect of being exposed.
