Here, the release button 34 is provided with two push pieces 34a, and the lock pieces 33 of the two lock springs 33 provided in the terminal device 30b.
Since b is pressed at the same time, if two electric wires are connected to the terminal device 30b, pressing one release button 34 can release the mechanical holding of the two electric wires at the same time. Similarly, if a tool is inserted into the operation hole 15 on the side of the terminal devices 30c and 30d and the release button 34 is pressed while the electric wires are connected to the terminal devices 30c and 30d, respectively, the locking piece 33b is separated from the electric wires. The wires are bent to release the mechanical holding of the electric wires, and the electric wires can be pulled out from the body 1.

Therefore, it is possible to prevent a dark portion from being formed on the display surface 81a. Here, the second reflecting surface 82c of the prism 80 of FIG. 6 has two step surfaces 82d, and the second reflecting surface 82c of the prism 80 of FIG. 7 has five step surfaces 82d. The prism 80 of 7 can more efficiently emit the light of the light emitting source 70 to the outside than the prism 80 of FIG. 6, but the smaller the number of the step surfaces 82d is, the easier the molding is. It only has to have 82d.
