にケーブル４およびコネクタを介して着脱される。<Prior Art> FIG. 8 is a structural explanatory view showing an example of a conventional probe for an optical power measuring instrument. In the figure, one end of the probe main body 1 is formed to be flat and provided with a light receiving window 2, and inside this light receiving window 2, a light receiving element for detecting the light to be measured is arranged. The other end is formed as a grip 3. The probe configured as described above is attached to and detached from an optical power measuring device (not shown) via the cable 4 and the connector.
ところで、このようなプロープを用いて測定するのに
あたっては、受光窓２から受光素子に入力される光を遮
って零リセットを行う必要がある。By the way, in the measurement using such a probe, it is necessary to block the light input to the light receiving element from the light receiving window 2 and perform the zero reset.

ーブル17およびコネクタを介して着脱される。FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view of an essential part of FIG. In the figure, one end of the probe main body 6 is formed flat and a light receiving window 7 is provided, and a light receiving element 8 for detecting the light to be measured is arranged inside. A grip portion 9 is provided at the other end. Shutter member
10 is the probe body 6 so that the light receiving window 7 can be opened and closed at one end.
Is arranged movably in the longitudinal direction, and the other end is extended to the grip portion 9. The operation knob 11 is composed of an operation section 12 and a columnar section 13 vertically attached to the back surface of the operation section 12. The operation knob 11 is attached to the probe body 6 so that the operation portion 12 moves along the movement direction of the shutter member 10 on the surface of the grip portion 9, and the end of the column portion 13 is a shutter inside the probe body 6. It is connected to the end of the member 10. The grip portion 9 of the probe body 6 has an operation knob 11 communicating with the inside of the probe body 6 as shown in FIG.
An oval hole 14 is formed to guide the. This hole 14
The columnar portion 13 of the operation knob 11 is inserted therein, and positioning projections 15 and 16 for regulating the position of the columnar portion 13 of the operation knob 11 are provided on the inner periphery at positions for opening and closing the light receiving window 7. The probe configured in this manner is attached to and detached from an optical power measuring device (not shown) via the cable 17 and the connector.

Operate 12, and the 11 column part 13 of the operation knob will
It moves toward the light receiving window 7 until it passes through. As a result, the shutter member 10 closes the light receiving window 7,
The light incident on the light receiving element 8 is blocked. Since the cylindrical portion 13 of the operation knob 11 passes through the positioning protrusion 15, the shutter member 10 is held in the state in which the light receiving window 7 is closed even if the user releases the operation portion 12 of the operation knob 11.
