BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch device used for a small device such as a clock.

[0002]

2. Description of the Related Art In an alarm clock that emits an alarm sound at a preset time, a push button switch is provided on the upper surface of a watch case, and when the push button switch is pressed, the emission of the alarm sound is stopped. It is supposed to. Such a push button switch has a structure in which a plate-shaped button portion is disposed substantially at the center of the upper surface of a watch case, a shaft portion is provided at the center of the lower surface of the button portion, and the shaft portion is held movably up and down. ing.

[0003]

However, in such a conventional push-button switch, even if the size of the flat button portion is increased, pressing the edge portion of the button portion only causes the button portion to tilt and the shaft portion to be tilted. Since it does not move up and down smoothly, it is necessary to press the center part of the button part at the time of pressing operation, so that there is a problem that the operation range of the switch is narrowed and the operability of the switch is poor. The present invention has been made in view of the above-described circumstances, and an object of the invention is to provide a switch device capable of expanding a switch operation range and improving switch operability. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In these figures, reference numeral 1 denotes a watch case (equipment case) . The watch case 1 has a structure in which a lower case 2 and an upper case 3 are mutually connected , and a speaker cover 4 as a cover member is provided on the upper case 3.

The lower case 2 is formed in a square box shape whose upper part is open. As shown in FIG. 3, a battery housing part 5 having an opening at the lower part is formed at the bottom of the lower case 2. A battery 6 is housed in the battery housing 5, and a battery cover 7 is detachably attached to a lower portion thereof. A lower circuit board 8 is provided at the bottom of the lower case 2 in the vicinity of the battery housing 5, supported by ribs 9. A slide switch 1 is provided on the lower surface of the lower circuit board 8.
0 and a push button switch 11 are provided with their lower ends protruding below the lower case 2 respectively.

The upper case 3 has a structure in which a cylindrical portion is formed integrally with an upper portion of a rectangular box whose lower portion is open. As shown in FIG. 2, an upper circuit board 12 is attached to the lower side of the upper case 3 with screws 13. The upper circuit board 12 is electrically connected to the lower circuit board 8 by a flexible sheet 14. Further, a speaker 15 for emitting the time by voice is attached to the upper part in the upper case 3 by a screw 15a. Note that the speaker 15 is electrically connected to the upper circuit board 12.

As shown in FIG. 3, a liquid crystal display device 16 is disposed on the front surface extending over both the lower case 2 and the upper case 3. The liquid crystal display device 16 is for electro-optically displaying information such as time and the like. The liquid crystal display device 16 is attached to a mounting plate 18 attached to the upper case 3 by screws 17, and the upper circuit board 12
Is electrically connected to

The speaker cover 4 is formed in a hemispherical shape.
It is attached to the upper part of the upper case 3 by screws 21. As shown in FIG. 1, a large number of slit-shaped sound emission holes 22 are formed on the surface of the speaker cover 4 in parallel in the left-right direction.
As shown in the figure, the storage groove 23 is formed in parallel with the sound emission hole 22.

[0010] As shown in FIG.
From the one end (left end) to the other end (right end) through the upper part, a semicircular operating member 24 is arranged with its surface slightly projecting. One end of the operating member 24 is rotatably attached to the inner wall of the storage groove 23 by a rotating shaft 25, and the other end is inserted into a stupid hole 26 formed in the upper case 3. The other end has a stupid hole 2
6 is provided with a stopper portion 27 that contacts the lower edge portion.

A switch member 28 such as a micro tact switch is provided on the upper circuit board 12 facing the lower side of the other end of the operation member 24. The switch member 28 has a relatively short operation stroke that switches when pressed by the other end of the operation member 24. Usually, the operation member 28a is urged upward by a spring member (not shown). The operation member 24
Is pushed up. A recess 29 is formed in the center of the storage groove 23, and a coil spring 30 for urging the operation member 24 upward is stored in the recess 29.

In such an electronic timepiece, the time can be known by the liquid crystal display device 16 in a bright place such as the daytime, and when the operation member 24 is pressed in a dark place such as the nighttime, the operation around the rotary shaft 25 is performed. The member 24 is the coil spring 3
0, and the other end of the operating member 24 pushes down the operating member 28a of the switch member 28 to turn on the switch member 28, so that the time is output from the speaker 15 based on the ON signal. Sound can be emitted by voice.

As described above, in this electronic timepiece, the operating member 24 is formed in a semicircular shape, and the operating member 24 is arranged outside the speaker cover 4 from one end to the upper end through the other end. Since the exposed portion of the operating member 24 is increased, and one end of the operating member 24 is rotatably supported by the rotating shaft 25, the operating member 2 excluding the portion of the rotating shaft 25 is removed.
Even if any part of 4 is pressed, the operation member 24 rotates and the switch member 28 can be switched, so that the operation range is widened and the switch operability can be improved. In this case, the hemispherical speaker cover 4
The outer surface is provided from one end to the other end through the upper part.
In the recessed storage groove 23, the operation member 24 is
Since it is arranged movably in the depth direction, the storage groove 2
3, the operation member 24 can be guided.
Therefore, when pressing the operation member 24, the operation member 24
It can be operated smoothly without causing runout.
Thereby, switch operability can be improved.

In the above-described embodiment, a case has been described in which the present invention is applied to an electronic timepiece that emits time by voice.
The present invention is not limited to this, and can be widely applied to other clocks such as an alarm clock that emits an alarm sound at a preset time.

[0015]

As described above, according to the present invention, the operating member is formed in an arc shape, and the operating member is substantially
On the outer surface of the spherical cover member, from one end to the upper
It is moved in the depth direction into the storage groove provided over the end.
While movably arranged, insert one end of the operating member into the storage groove
The switch member is rotatably supported at one end of the switch member and is switched to the other end of the operation member by a pressing operation of the operation member, so that the operation range of the switch can be widened. Operation member by storage groove
Can be guided, so that when the operating member is pressed
The operation member can be prevented from running sideways, and the operation member can be smoothly
Can be operated to improve switch operability.
be able to.
