1000Kg/cm ² , preferred hardness is Shore A hardness 60
Above, the Shore D hardness is 80 or less. By providing the sloped portion 4a on the body 4 and the sloped portion 3c on the keyboard fixing frame 3, the keyboard fixing frame 3 enclosing the key buttons 1 and the keyboard 2 can be easily inserted into the body. Furthermore, by using an electrically conductive material for the keyboard fixing frame 3 or by forming an electrically conductive member at the tip of the protrusion 3b of the keyboard fixing frame 3, the conductive plate 6 of the movement 6
b. The spacer 6c can also be removed. 1
0 is a cover glass made of inorganic glass, and 20 is a waterproof ring (made of synthetic resin) that attaches the cover glass 10 to the body 4.

6d is a display panel such as a liquid crystal panel, an electrochromic panel, or an electroluminescent panel in the display section. 4b is a sound emitting hole in the body, 6e is a sound device such as an electromagnetic buzzer or a piezoelectric buzzer, and 8 is a metal
9 is a sound emitting pipe made of synthetic resin or the like, 9 is a sound emitting gasket made of synthetic rubber or synthetic resin, 6f is a sound device fixing frame made of metal synthetic resin, etc., and 6g is a sound device fixing frame gasket made of synthetic rubber or synthetic resin. . The key buttons 1 and the keyboard 2 of the key input section are arranged at the front (6 o'clock side) and inserted from the glass side, that is, the front side of the body. Display panel 6d of display section
As seen in FIG. 3, it is placed in the center of the case in its planar arrangement, and is inserted from the back cover side. The sound device 6e of the sound emitting section is inserted from the back cover side and is placed on the back cover side below the display panel 6d, and the sound is emitted from a position that is planarly different from the display panel 6d (12 o'clock side). The sound is emitted through the pipe 8 and from the sound emitting hole 4b. The outer shape of the movement 6 is circular. FIG. 4 is an example of an application in which the number of key buttons is increased.

Furthermore, by arranging the battery below the key buttons, the keyboard, and the display panel 6d so as to overlap them on the side of the audio device 6e, it is possible to effectively arrange the battery in a two-dimensional manner and to make the thickness as thin as possible.

Regarding FIGS. 3 and 4, the bands are fixed to the upper and lower sides of each figure. Further, 6h in FIG. 2 is a spring portion of the synthetic resin portion of the movement 6, and the spring portion 6h presses against the back cover 5 to push and hold the movement upward.

As described above, according to the present invention, since the outer shape of the movement housed in the body is circular, the movement housing part, which has the largest processing area and volume in the body, can be processed by simple sawing, milling, etc. It is much easier to manufacture and improves dimensional accuracy compared to non-circular shape machining. Moreover, since the key buttons, display panel, sound device, and sound emitting hole fit within the circular shape of this movement, there are openings for conduction paths between the lower part of each key button in the body and the circuit board, etc. on the movement side. The central opening where the display panel is placed facing each other and the sound emitting hole can be easily processed by simple press processing, drilling, etc. after the movement housing section has been processed in advance, making processing of the body extremely easy. Become.

On the other hand, since the key buttons and keyboard are arranged above the inner step of the body, there is also the advantage that the design can be done without being influenced by the shape of the lower movement or the back cover.

Furthermore, since the display panel can be sandwiched between the key buttons and the sound emitting hole and positioned almost in the center of the circular movement outer shape, the display area can be maximized, making it an easy-to-read display. .

Furthermore, since the key buttons are arranged on the 6 o'clock side of the display panel, it is convenient to operate while looking at the display on the display panel when inputting keys. Furthermore, by arranging the sound emitting hole on the 12 o'clock side of the display panel, the limited body can be used effectively, and since the sound is emitted from the front side of the body, the volume of sound emitted is also increased.

Furthermore, since the acoustic device is placed overlappingly on the back cover side of the display panel, a more compact case size can be obtained compared to the case where the acoustic device is placed parallel to the display panel in a plane.
