PROBLEM TO BE SOLVED: To play a melody, by tilting a sensor piece by contacting a contact piece projecting outwardly from a lock part, bringing a part of a conductive coil spring into contact with an inner surface of a conductive tube piece by a shaft part of the sensor piece, and thereby closing an electric circuit connected to electric contacts. SOLUTION: An electric circuit board 30 is equipped with a sound signal generating device storing a cheerful melody, a control device, and the like. A power switch is installed near a speaker or a grip of an exterior material 2. A sensor piece 21 is tilted by a contact motion of a contact piece 23 of a detective sensor with an object to be inspected, and a part of a conductive coil spring 32 is brought into contact with an inner surface of a conductive tube piece 31. Because of this, an electric circuit of the sound signal generating device connected to electric contacts 32a, 31a of the conductive coil spring 32 and of the conductive tube piece 31 is closed, and the speaker connected to the sound signal generating device plays the melody. A brush member can be easily detached from a main body and therefore maintenance is easily performed. |
