Then the telephone set main body 10 is provided with an operation section 18 provided with a key group used comparatively frequently such as a ten-key, a # key, a * key, a dial key, a reply key and an erasure key in addition of a speaker 14, a display section 15, an antenna 16, and a battery 17, and the moving section 13 is provided with a key group 19 with comparatively low use of frequency such as a power supply key, a mute key and a recall key.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone having an improved arrangement of key switches and the like.

[0002]

2. Description of the Related Art As a portable telephone which is small and lightweight and is suitable for carrying, there is, for example, one shown in FIGS. 2 (a) and 2 (b).
The telephone main body 1 is composed of a movable portion (sending portion) 4 pivotally supported by a rotating mechanism 2 located at a lower end portion thereof so as to be openable and closable and provided with a microphone 3. The telephone body 1 is provided with a speaker 5, an operation unit 6 and a display unit 7 located below the speaker 5, an antenna 8, a battery 9, and the like. When making a call, the movable part 4 is used with the rotating mechanism 2 as the center, as shown in FIG. 2 (a), and when not in use, the movable part 4 is folded and closed on the side of the telephone body 1 as shown in (b). To be compact. Also,
Contrary to the above, there is also a type of telephone in which the display section 7 is provided on the telephone body 1 side and the movable section 4 is provided with the operation section 6.

By the way, the operating section 6 is composed of a plurality of key switches. However, in a conventional mobile phone, the area occupied by the keyboard becomes smaller as the size of the phone becomes smaller. The key interval becomes small, making it difficult to visually recognize individual keys, and it becomes difficult to operate the keys with the fingertips, which easily causes erroneous operations. In particular, as the number of keys increases as the functions of the telephone increase, the tendency for the keys to become harder to press and harder to see is promoted.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is difficult to visually recognize and operate the keys due to the miniaturization of the keys caused by the downsizing of the telephone and the increase in the number of keys caused by the increased functions of the telephone. It is an object of the present invention to provide a keyboard of a mobile phone capable of preventing the complexity of the above and the occurrence of erroneous operations due to them.

[0005]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides a portable telephone comprising a telephone body having a speaker and a movable portion having a microphone openably and closably connected to a lower end portion of the telephone body. It is characterized in that a frequently used key is arranged on one of the main body side and the movable part side, and a less frequently used key is arranged on the other side.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 shows a portable telephone according to an embodiment of the present invention. The portable telephone is opened and closed in the arrow direction by a telephone body 10 held by a telephone and a rotating mechanism 11 located at the lower end of the telephone body 10. A movable part (speaker) that is freely pivoted and equipped with a microphone 12
It is composed of 13 and. When making a call, the movable part 13 is used with the rotating mechanism 11 as the center as shown in the figure, and when not in use, it is folded and closed on the side of the telephone body 10 to be compact.

The telephone body 10 includes a speaker 14, a display section 15, an antenna 16, a battery 17, a numeric keypad,
The operation unit 18 is provided with a group of relatively frequently used keys such as the # key, the * key, the calling key, the response key, and the delete key.
The movable portion 13 is provided with a key group 19 that is used relatively infrequently, such as a power key, a mute key, and a recall key. In addition,
Contact signals from the keys on the movable unit 13 are output to a control unit provided on the telephone body side via a flexible printed board or the like.

The operation section 18 on the main body 10 side is provided with keys that are used relatively frequently as shown in the above example.
Since which key is frequently used is different depending on the function of the telephone, the present invention is not limited to the above-exemplified keys. Similarly, it is not intended to limit the keys used infrequently to the types of keys exemplified above.

Thus, according to the present invention, the telephone body 1
Since the keys are arranged on both the 0 side and the movable portion 13, it is possible to secure a large occupied area of the keys, and as a result, it is not necessary to downsize each key or reduce the key interval, and to operate the keys. Easy and easy-to-see keys prevent erroneous operation.
In addition, even if the number of keys increases due to the function improvement of the telephone, the additional keys that are rarely used will be placed on the movable part side, so that the keys will be downsized, the key interval will be shortened, and erroneous operation due to these will occur. Occurrence can be prevented.

It is to be noted that a key group which is not frequently used may be arranged on the main body 10 side and a key which is frequently used may be arranged on the movable portion 13 side, and the same effect as that of the above embodiment can be obtained. Is.

[0011]

As described above, according to the present invention, it is difficult to visually recognize the keys and the operation is complicated due to the miniaturization of the keys caused by the downsizing of the telephone and the increase in the number of keys caused by the increase of the functions of the telephone. And, it is possible to prevent the occurrence of erroneous operations due to them.
