る。FIG. 1 is a structural explanatory view showing an embodiment of the present invention,
(A) is a front view, (b) is a sectional view taken along the line AA of (a), (c)
FIG. 7B is a BB sectional view of (b). In the figure, reference numeral 6 is a front plate which constitutes a case in which a light source (not shown) is housed. A connector 7 is attached to the front plate 6 of this case so as to form a light emission port. Reference numeral 8 denotes a shutter, which is formed in a cylindrical shape with a bottom, and a hole 9 corresponding to an emission port formed by the connector 7 is formed on the front plate 6 of the case on the bottom surface so that the end surface of the connector 7 is enclosed. Is rotatably attached to the front plate 6 via a shaft 10 and an E ring 11. Reference numeral 12 denotes a torsion coil spring, the center of which is fitted to the shaft 10, one end of which is locked by a pin 13 mounted on the inner wall of the shutter 8 and the other end of which is locked by a pin 14 mounted on the front surface 6 of the case. ing. Reference numeral 15 is a stopper pin that restricts the rotation angle of the shutter 8 and is attached to the front plate 6 of the case. Here, in the stopper pin 15, the hole 9 of the shutter 8 does not overlap the connector 7 in a normal state in which the connector of the optical cable (not shown) is not fitted and connected to the connector 7 (a).
Is attached so as to be in the first position indicated by the solid line.

８をシャッタ８の穴９とコネクタ７と重なりあう（ａ）
に１点鎖線で示す第２の位置までバネ12の復帰力に抗し
て反時計方向に約75°回転させて光ケーブルのコネクタ
を挿入する。In such a configuration, when the connector of the optical cable (not shown) is fitted and connected to the connector 7, the shutter 8 overlaps the hole 9 of the shutter 8 and the connector 7 (a).
Then, the connector of the optical cable is inserted by rotating counterclockwise about 75 ° against the restoring force of the spring 12 to the second position indicated by the one-dot chain line.
一方、これらコネクタ相互の嵌合を解除して光ケーブ
ルを引き抜くことにより、シャッタ８はバネ12の復帰力
によってシャッタ８の穴９とコネクタ７が重なりあわな
い第１の位置（初期位置）に瞬時に回転復帰する。これ
により、コネクタ７から出射される光はシャッタ８で遮
断されることになる。On the other hand, when the connectors are released from each other and the optical cable is pulled out, the shutter 8 instantly moves to the first position (initial position) where the hole 9 of the shutter 8 and the connector 7 do not overlap each other due to the restoring force of the spring 12. Return to rotation. As a result, the light emitted from the connector 7 is blocked by the shutter 8.
このように構成することにより、従来のような２動作
は不要になり、シャッタ８を回転させる１動作のみで光
の出射口の開閉が行える。With such a configuration, it is not necessary to perform the conventional two operations, and only one operation of rotating the shutter 8 can open and close the light emission port.
そして、シャッタ８はバネ12で回転付勢されているの
で、装置の配置面が傾斜していても安定した開閉動作が
得られる。Further, since the shutter 8 is rotationally biased by the spring 12, the stable opening / closing operation can be obtained even if the arrangement surface of the device is inclined.
さらに、光の出射口を形成するコネクタ７の端部が円
筒型に形成されているシャッタ８に内包されているの
で、従来の構成に比べてシャッタ８からの出力光の漏れ
は大幅に改善される。Further, since the end portion of the connector 7 forming the light emission port is contained in the shutter 8 formed in a cylindrical shape, the leakage of the output light from the shutter 8 is significantly improved as compared with the conventional configuration. It
なお、上記実施例では安定化レーザー光源に適用した
例を説明したが、その他の光源装置のシャッタ機構とし
ても有効である。In addition, although the example applied to the stabilized laser light source has been described in the above embodiment, the shutter mechanism of other light source devices is also effective.
〈考案の効果〉 以上説明したように、本考案によれば、比較的簡単な
