DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small portable telephone.

[0002]

2. Description of the Related Art A portable telephone as a terminal in a wireless telephone system including a PHS (simplified portable telephone system) has several function keys in addition to numeric keys as operation keys, and at least ten and several keys are provided. The aircraft has a height of 90 mm or more and a width of several tens.
mm, a thickness of 20 mm or more, and a weight of 80 to 200 g in most cases.

[0003] Also, an emergency call function-equipped elderly telephone capable of transmitting a call to a pre-registered destination by operating a special key for emergency call has been put into practical use and registered in a built-in storage device in advance. A mobile phone having a one-touch dial function for dialing the set telephone number by operating one key has already been implemented.

On the outside of the telephone receiving section, a sound hole is formed in a flat or concave wall surface of the telephone case, and a speaker is provided inside the sound hole. In many cases, an antenna is provided so as to protrude from the top of the case. There is also a telescopic structure that can be used.

M is an essential component, and the space occupied by the numeric keypad prevents miniaturization.

A battery, an electronic circuit, a storage device, an antenna, a microphone, a speaker, and the like provided in a mobile phone can be individually reduced in size and weight due to technological progress. Although the size of the telephone can be reduced to some extent due to the development of the telephone, the surface area occupied by the numeric keypad requires a space of 30 mm × 35 mm, and the circuit associated with each key is also complicated and requires an occupied volume for the circuit. In relation, miniaturization is extremely difficult,
In addition, in consideration of operability, the size and pitch of the keys themselves are naturally limited in miniaturization, which is a major factor that hinders miniaturization of mobile phones.

[0008] In addition, although a portable telephone is an excellent means of communication for a salesperson, it is not desirable to be abused in a private call. There is a need for a means for prohibiting calls to destinations other than the destination. For this reason, in a conventional mobile phone with a one-touch dial function, it is conceivable that calling cannot be made to a destination other than, for example, several destinations corresponding to one-touch dial keys. However, there are disadvantages in that the facilities and the occupied volume related to the numeric keypad are wasted, and the user's psychological dissatisfaction with intentionally disabling the available functions remains strong.

It is therefore an object of the present invention to reduce the size and weight of a telephone body and a power supply battery as much as possible, to provide a portable telephone which cannot make calls except to a limited number of destinations, and to provide an inexpensive portable telephone. To provide.

[0010]

In order to achieve the above object, according to the first aspect of the present invention, a ten-key pad is abolished, one one-touch dial key is provided, and a ROM for storing a telephone number of a destination is built in. In addition, by operating the one-touch dial key, a call is made to the telephone number stored in the ROM, and the invention according to claim 2 further comprises a plurality of one-touch dial keys. The respective destination telephone numbers are stored in the ROM.

The invention according to claim 3 is characterized in that an elastic clip / antenna adapted to hold the periphery of the clothes is extended from near the top end of the body to a state along the outer wall surface of the body.
The invention according to a fourth aspect is characterized in that an earphone-shaped horn portion is provided in a protruding state on the earpiece, and the invention according to a fifth aspect is characterized in that the earpiece is provided so as to be able to come and go from the body.

Since the internal ROM of the telephone cannot be changed, only a call to a telephone number stored in advance in the ROM can be made by pressing a one-touch dial, and it is impossible to make a call to another destination. Yes, it is possible to receive from any other party as in a normal telephone.

By inserting the edge of the pocket into the gap between the body and the elastic clip and antenna while inserting the body of the telephone into the pocket of the clothes, the phone is stably held in the pocket, and the antenna is exposed to the outside. A sufficient length is ensured, and radio waves are transmitted and received efficiently.

The horn section formed in the receiving section is fitted into a concave portion of the ear during a call to prevent intrusion of external noise and sound leakage to the outside, so that listening can be performed with high sensitivity.
