【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 4 are partial cross-sectional views for explaining the structure and operation of the portable buzzer of the embodiment, and FIG. 5 is a perspective view showing the appearance. In these figures, 1 is a case body of a portable buzzer, 2 is a buzzer which is a sounding body, and 3 is a button type battery for ringing the buzzer 2. An operating portion 4a of a switch lever 4 for ringing or stopping ringing of the buzzer 3 is exposed to the outside of the case body 1 above the case body 1 in the figure, and a column provided on the case body 1 in the vertical direction in the figure. It can be pulled out to a predetermined position along 1a and side plate 1b. 1 and 2 show a normal state in which the switch lever 4 is pulled into the case body 1 and the buzzer 3 does not ring, and FIGS. 3 and 4 pull out the switch lever 4 from the case body 1 to ring the buzzer 3. Indicates an alarm condition. Two arms 4b, which can be bent by the elastic force shown in FIGS. 1 and 3, are provided on both sides of the switch lever 4, and a mountain-shaped projection 4c is provided at the tip of these arms 4b. ing. Further, the case body 1 is provided with a protruding portion 1c which elastically abuts against the chevron-shaped protrusion 4c when the switch lever 4 is pulled out from the case body 1. The protrusion 1c has such a height that the protrusion 4c can ride over the protrusion 1c when the switch lever 4 is moved, and the protrusion 4c contacts the protrusion 1c to move the switch lever 4 However, the arm 4b bends and the protrusion 4c rides over the protrusion 1c so that the switch lever 4 can be pulled out.

In this way, the protrusion 4c is elastically brought into contact with the protruding portion 1c, and the protrusion 4c is passed over the protrusion 4c, so that the pulling operation of the switch lever 4 has a moderation to prevent the switch lever 4 from being pulled out by mistake. There is.

The button type battery 3 is held by the switch lever 4 by a holding rib 4 d and a holding rib 4 e provided on the switch lever 4, and moves in the same direction together with the switch lever 4. The negative electrode contact 5a for contacting the negative electrode terminal 3a of the battery 3 is fixed to the case body 1 via the substrate 6 on which the drive circuit 2a of the buzzer 2 is mounted, and the elongated hole 4f provided in the switch lever 4 and It contacts the negative electrode terminal 3a of the battery 3 through the side plate 1b of the case body 1. When the battery 3 moves together with the switch lever 4, the negative electrode terminal 3a is kept in contact with the negative electrode contact 5a while sliding. On the other hand, two positive electrode contacts 5b for contacting the positive electrode terminal 3b of the battery 3 are provided fixed to the case body 1 along both sides of the switch lever 4. When the battery 3 moves upward in the figure together with the switch lever 4, the positive electrode terminal 3b, which also serves as the case of the battery 3, contacts the positive electrode contact 5b to conduct electricity.
