DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-sized portable telephone, and particularly to a portable telephone in which portability is emphasized and, for example, pocketable.

[0002]

2. Description of the Related Art In a conventional portable telephone, for example, a telephone described in Nikkei Electronics 1990.4.16 (No. 497), pp. 113-131, entitled "Special Feature Mobile Phone", The numeric keypad part of the dial for outgoing calls requires the number buttons corresponding to the dialed numbers,
For example, it is arranged in the form of a push button, and when a call is made, the call number is input and set by pressing the push button corresponding to the dialed number.

The drawback of this prior art is that it is necessary to provide a number of push buttons corresponding to the numbers on the numeric keypad, so that the surface area and mounting volume required for the arrangement of the push buttons are required, and the surface area and mounting volume are large. It had the drawback of forming.

[0004] In addition, since a large number of push buttons having the same shape are arranged side by side, this may cause a transmission error due to a wrong push.

[0005]

The above-mentioned push button
Function of one rotary dial plate and one diamond
By having only the switch for setting,
Significant reduction in surface area and mounting volume of dial keypad
In addition, the mobile phone can be miniaturized.

[Means for Solving the Problems] A rotary dial plate with a changeover switch function for switching connection and a dial numeral selected by the rotary dial plate are set for each digit in accordance with the numeric keypad part of the dial for transmission. A push button switch for dial setting is provided, and a function of sequentially setting the dialed number by a combination operation thereof is provided. In order to solve the above-mentioned problem, the present invention relates to a telephone that can be held by a user, and is arranged at a position that is partially exposed from a side of the housing of the telephone and that can be operated by a finger of a hand holding the telephone. And
A rotator for selecting a dial number for transmission for each digit, and a rotator disposed on a side of the housing of the telephone and operable by a finger operating the rotator; A number setting unit for setting the selected dial number digit by digit, a display unit for displaying the dial number set by the number setting unit, and a position operable by a finger operating the rotating body And a call start instruction setting unit for instructing a start of a call with the dial number displayed on the display unit, and when a call start instruction is set in the call start instruction setting unit, the display unit And a control unit for controlling to start calling with the dial number displayed on the control panel.

[0006]

[0007]

According to the above-described structure, as a procedure for performing a calling operation, first, the rotary dial plate is turned and selected to a predetermined position so as to be in a position corresponding to the number of the calling dial number. As an operation for inputting the number, an operation of pressing (ON) a push button switch for dial setting may be performed.

By repeating the above operation by the number of digits of the outgoing dial number, the input and setting of the outgoing dial number are completed.

The actual transmission operation is completed by a switch operation of pressing a predetermined transmission start button after inputting and setting operation of the transmission dial number.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIG. 1 is a schematic explanatory diagram showing a basic functional configuration according to the present invention, and also a diagram showing a state held in a hand at the time of dialing operation.

In the figure, a rotary dial plate 1 is
It has a structure that can be rotated with the thumb around the center pin 2, has an internal structure with a changeover switch function that can electrically switch the connection in accordance with each numerical value of the dial number, and In the rotating operation of the rotary dial plate, a so-called quick stop structure is employed so that the number of the dial number is easily stopped at a predetermined position.

In the vicinity of the circumference of the rotary dial plate 1, a dial number display window 3 is provided for identifying that the dial plate is at a predetermined position.
On the other hand, a push button switch 4 for dial setting
Has a push button switch function for actually inputting and setting the dialed number selected by the rotary dial plate 1 in an electric circuit, so that the dialed number can be input and set for each digit of the dialed number. It has become.

For this reason, a combination operation of selecting a digit of a dial number digit by digit with the rotary dial plate 1 and then inputting and setting with the dial setting push button switch 4 is performed by the number of digits of the dial number. A predetermined dial number is input and set by repeating the process sequentially.

Note that these results are displayed on the display unit 5 so that it is possible to confirm that there is no mistake in dial number entry.

As described above, the predetermined dial number is
After the input and settings are made, pressing the transmission start button 6 terminates the actual dial transmission operation.

Note that the speaker is configured so that it can be replaced by the earphone 7 in order to realize a very small size.
Also, the built-in microphone 8 can be a microphone that also serves as a speaker.

FIG. 2 is a diagram for explaining the electrical connection between the rotary dial plate 1 and the push button switch 2 for dial setting.
The connection of the rotary switch unit 9 in FIG. 2 is switched by rotating the rotary dial plate 1 around.

Further, it is shown that pressing the dial setting push button switch 4 turns on the number input and setting switch section 10 in FIG.

[0020]

The portable telephone according to the present invention has the function of the dial keypad part by only one rotary dial plate and one dial setting switch, thereby greatly increasing the surface area and mounting volume of the dial keypad part. This has the effect of minimizing the volume of the entire mobile phone, and at the same time is extremely excellent in usability, as it can be operated with one hand and one thumb.

Further, in a conventional numeric keypad in which a large number of push buttons having the same shape are arranged side by side, the present invention is also useful for preventing transmission errors caused by erroneous pressing of the push buttons.

Further, in the conventional numeric keypad part, the power for illumination of that part cannot be ignored due to the large surface area. However, in the present invention, the numeral illumination of the dial number is extremely limited. It is only necessary to illuminate a partial area, and as a result, the effect on power saving is great.

It is needless to say that the rotary dial plate can be provided with not only the numbers of the dial numbers but also the function selection dial functions such as redialing and call forwarding.
