In this embodiment, the angles of the light emitting/light receiving means L and Q explained in FIG. 1 can be changed freely. That is, as shown in FIG. 3, a rotating part 16 rotatably attached to a shaft 15 is equipped with light emitting/light receiving means L and Q. When the electric drill driver 2 is set at an arbitrary angle by moving the rotating part 16,
Notification means 1 enables notification. In this embodiment, a buzzer 1b is provided as the notification means 1.

By attaching the angle detection plate 17 in this manner, it is possible to know how many degrees the electric drill driver 2 is tilted with respect to the object 13 to be drilled. Therefore, by setting the angle to a desired angle, it is possible to drill a hole with a desired slope, or to measure the angle by inserting a drill into an already drilled hole.

図６ではα傾いた傾いた例を示している。FIGS. 5 and 6 show still another embodiment of the present invention. In this embodiment, in addition to the embodiment shown in FIG. A plurality of light-receiving means Q1 for detection are arranged at the front. With such a configuration, as shown in FIG. 6, when the electric drill driver 2 is not perpendicular to the surface of the object 13 to be drilled, the reflected light is not reflected to the center and is sent to the surrounding light receiving means Q1 for detection. By detecting this light, it is possible to detect which direction the electric drill driver 2 is tilted. FIG. 6 shows an example where the angle is tilted by α.

１８は裏面に粘着層を設けておいてもよい。Next, another embodiment shown in FIG. 7 will be explained. If the surface of the object 13 to be drilled is not flat, the reflected light will not return straight but will be reflected diffusely due to the unevenness of the surface, making accurate detection impossible. Therefore, as shown in Fig. 7, a donut-shaped flat reflecting plate 18 is pasted to the center of the hole to be drilled, and the flat reflecting plate 18 directs the light accurately and straight. It can be reflected and accurate detection can be performed. Here, the mounting plate 18 may be provided with an adhesive layer on the back surface.
