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) on pages 113 to 131 entitled "Special Feature Cellular 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. In addition, since a large number of push buttons having the same shape are arranged side by side, it causes a transmission error due to a wrong push.

[0004]

The function of the push button described above is provided by providing only one rotary dial plate and one dial setting switch.
The surface area and the mounting volume of the dial numeric keypad are greatly reduced, and the mobile phone can be miniaturized.

[0005]

In addition, in order to solve the above problems, the present invention,
In a mobile phone that can be held by a user with one hand,
A part of the mobile phone being exposed from the housing of the mobile phone;
Is placed in a position that can be operated with the fingers of the hand holding the
A rolling body, a control information generating unit that generates control information for controlling the mobile phone according to the rotation amount of the rotator, and an intended content of the control information based on the control information generated by the control information generating unit. The display unit to display and operate the rotating body
The control information
An input unit for inputting an instruction to execute the contents of the information,
A control unit that controls the mobile phone based on an instruction input to the input unit . Further, in order to solve the above-mentioned problem, the present invention relates to a method of transmitting a telephone which can be held by a user with one hand, wherein the user is partially exposed from a housing of the telephone and can be operated with a finger of the hand holding the telephone. Detects the operation amount of the rotating body arranged at an appropriate position, displays a dial number according to the operation amount of the rotating body, and issues a transmission start instruction input by the same finger as the finger that operated the rotating body. Accepting and starting the transmission with the displayed dial number when the transmission start instruction is input.

[0006]

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 the input and setting operation of the transmission dial number is completed.

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 drawing, 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 for identifying that the dial plate is at a predetermined position is provided.
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 such as selecting the digits of the dial number digit by digit on 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.

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

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 the earphone 7 can be used in place of the speaker 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 view 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.

Also, pressing the dial setting push button switch 4 turns on the number input and setting switch section 10 of FIG.

[0019]

The portable telephone according to the present invention has the function of the dial numeric keypad by providing only one rotary dial plate and one dial setting switch, thereby greatly increasing the surface area and mounting volume of the dial numeric keypad. 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 many push buttons of the same shape are arranged side by side, it also helps to prevent a transmission error caused by a wrong push button press.

Further, in the conventional numeric keypad part, the power for illumination of that part could not be neglected 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 have not only the numbers of the dial numbers but also the functions of a function selection dial such as redialing and call forwarding.
