2. Description of the Related Art Conventionally, as a reflecting mirror device, a reflecting mirror device using a prism called a corner cube and a reflecting mirror device using a reflecting sheet are known. The reflector device using the prism is used for distance measurement,
Since the corner cube is made of glass, bulky and heavy, it is difficult to handle and the cost is high.

In addition, a reflector for a surveying instrument is provided with a vertical support shaft on a base, a support frame is provided on the vertical support shaft, a horizontal support shaft is formed on the support frame, and a reflection sheet is provided on the horizontal support shaft. A technique in which a body is rotatably arranged is known. This reflection sheet body is formed by adhering and integrating a reflection sheet with a micro-prism group formed on the back surface of a base plate, and the reflection sheet body is supported by a horizontal support shaft, a support frame and a vertical support shaft around a horizontal support shaft and a vertical support shaft. The reflecting sheet can be freely tilted and inverted by rotating around the axes, respectively, and can easily be brought into a state directly facing the distance measuring and measuring instrument. The reflecting mirror device using the reflecting sheet has advantages of being lightweight, not heavy, and low in cost.

However, when the reflecting mirror device using the conventional reflecting sheet is used at night or in a dark environment such as in a tunnel, the reflecting sheet body which is the target of the rangefinder. I didn't know the position of, and I was obliged to do surveying while the reflective sheet was illuminated with a flashlight.
Therefore, there is a problem that it is necessary to illuminate the reflection sheet body, and the work is troublesome, and an operator is required for this illumination, which results in very poor workability.

A reflecting mirror device intended for use at night or in a dark environment such as in a tunnel has also been proposed. For example, a proposed technique in which an illumination light source is detachably arranged behind a corner prism (for example, Japanese Utility Model Laid-Open No. 62-14697).
6), a proposed technique (see Japanese Utility Model Laid-Open No. 61-34410) in which a back surface of a front plate provided with a notch is attached to a survey sticking plate, and the back surface is constituted by an electronic illuminating plate. ing.

However, as described above, the corner prism has the disadvantages that it is difficult to handle because it is bulky and heavy, and that it is expensive, and the pasting plate is intended for angle measurement. Since it is illuminated only from the notch, it is difficult to determine.

An object of the present invention is to provide a reflecting mirror device for a surveying instrument using a reflecting sheet capable of both distance measurement and angle measurement and having good surveying workability in dark conditions such as at night.
