JPH11146044A - Telephone set - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a telephone set that gives no effect on a speech and by which the user does not feel bored. SOLUTION: A telephone set has a display section 13, an entry means 12, a storage means 11 and a control means (control circuit 10). A control section 10 detects that the entry means 12 is not operated for a prescribed time and allow a display section 13 to display intermittently a display independently of the telephone operations, e.g. pattern information selected among plural pattern information sets stored in a storage means 11. Since the pattern information is selected at random, unexpected performance is attained, and since the pattern is moved intermittently, it is not only interesting but also providing recognition of an operating state. In this case, display of information sets D1-D4 relating to a speech is preferably stopped, and the pattern is displayed in the standby state to avoid effect on a speech. The intermittent display of the pattern information is conducted preferably almost for the same period as the period of searching of the speech zone.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In recent years, as disclosed in Japanese Patent Application Laid-Open No. Hei 8-237393, a telephone has a display unit having a relatively large display capacity, and even a portable telephone has almost no display unit. The display is always displayed.

[0003]

Although the information to be displayed is often a telephone number or a date, the telephone number is displayed even when there is no intention to make a call, or personal information such as a fashion clock is displayed. When the belongings are diversifying, it is not necessary for the telephone to keep displaying the time.
Rather, it is preferable to devise the display contents in consideration of the fact that the telephone is a personal belonging of fashion. However, displaying a moving image such as a television broadcast consumes a lot of power, and a fixed display that is not related to a telephone for a long time must not be mistaken as a failure, and further impairs the function of the call. It must not be.

FIG. 1 is a block diagram of a telephone according to an embodiment of the present invention, and shows a PHS (Personal Handy-).
Although a public terminal of a second generation cordless telephone system called "phone system" is taken as an example, a child terminal of a cordless telephone system may be used. The configuration of the main part of such a telephone will be described.

In FIG. 1, reference numeral 1 denotes a receiving circuit, which receives radio waves from a public base station, a master unit, and another slave unit via an antenna 2. A transmission circuit 3 transmits a signal from a channel / voice codec 5 described later to a public base station or the like via the antenna 2. Reference numeral 4 denotes a PLL (circuit) that changes the transmission and reception frequencies of the reception circuit 1 and the transmission circuit 3.

Reference numeral 5 denotes a channel / voice codec, in which a channel codec (not shown) and a voice codec (not shown) are incorporated in one IC. The channel codec section is TDMA / TDD (time division multiple access /
It performs time-division duplex processing, CRC error detection, and QPSK demodulation. The audio codec unit compresses and expands audio, and performs analog and digital conversion.

Reference numeral 6 denotes a speaker, which converts the electric signal of the channel / audio codec 5 amplified by the amplifier circuit 7 into audio. Reference numeral 8 denotes a microphone that converts sound into an electric signal. Reference numeral 9 denotes an amplification circuit, which amplifies the output of the microphone 8 and outputs the amplified output to the channel / audio codec 5.

Reference numeral 10 denotes a control circuit composed of a microprocessor, which is a control means for controlling each unit based on a ROM storing an operation program (not shown here because it is sometimes integrated with the microprocessor). 11
Is a storage means composed of a RAM, a ROM, and the like.
The information necessary for the operation of 0, for example, a public telephone number, a position registration flag (value of a variable F), and a plurality of symbol information are stored. 12
Is an input means for inputting a telephone number, performing an operation for calling a public base station, or setting a mode.
Reference numeral 13 denotes a display unit, as shown in FIG.
It comprises a liquid crystal display having a symbol and a three-stage dot matrix display section MT. The fixed characters (including symbols) are: the phone mark D1 is calling, the antenna D2 is the signal strength indication within the calling area, the kana / English D3 is in the input mode, the public / home / transceiver symbol D4 is the calling mode, and finally the battery These fixed characters, which are symbols of the remaining amount B, are selectively displayed.

In such a configuration, the control circuit 10 performs display according to the mode. For example, in a portable telephone such as a PHS, there is a standby state in which so-called incoming call detection is performed at fixed time intervals. When the time display PHS standby is performed, as shown in FIG. 3, the antenna D2 in the fixed characters, the public D4, The battery level B is turned on, and the date is displayed in the second row of the dot matrix display section MT, and the time is displayed in the third row.

In a conventional telephone, this display is continued forever until the mode is changed, but in the present invention, at this time, the control circuit 10 is in a standby state, and
Detecting that the input means 12 has not been operated for 5 minutes, the display unit 13 displays a display irrelevant to the telephone operation, for example, symbol information selected from a plurality of symbol information stored in the storage unit 11. In the case of FIG. 2, one screen is formed by using a three-stage dot matrix display section MT, and "fish" is displayed.

It is preferable to prepare a plurality of types of such symbol information and to move the symbols intermittently. For example, prepare three types such as “fish”, “airplane” and “mole”, and choose which to read out at random by using random numbers, or select (pseudo) random symbol information by time zone function. It is preferable that the user cannot predict which symbol information is to be read. To move the pattern, the screen may be scrolled. However, the screen is not so large as to display the time and the telephone number at the most, and the dot information is stored in the storage unit 11 rather than calculating and determining the display position. Since it is easier to read out the power consumption, as shown in FIG. 4, a series of symbol information a to g consisting of seven screens is prepared, and the series of symbol information shows how the object (design) moves. This may be displayed sequentially at regular intervals. In the case of FIG. 4, “airplane” is shown.
If the screen is sequentially read out every 10 seconds toward g and displayed one screen at a time, the design of the airplane appears to move from the lower left of the screen to the upper right. If you don't know where to put your face from, such as "mole", the design is such that the head and face appear on the screen and greet and sink below the screen (sequential display)
It may be. Since the symbol information is selected at random, it is surprising that the symbol moves intermittently, so it is not only interesting but also recognized that the machine is operating normally.

By activating one of the keys of the input means 12, the control circuit 10 displays the standby state instead of disabling the function of the key (FIG. 3). Or the control circuit 10 forcibly switches the display when the call is received and enters the call receiving operation.

When displaying a symbol which is not directly related to the function of the telephone, it is preferable to stop displaying the information D1 to D4 relating to the telephone call. This is to prevent the image of the telephone from being left because the special symbol is displayed. On the other hand, the symbol display is performed during the standby state, so that the call is not affected. The intermittent display of the symbol information is preferably performed at substantially the same cycle as the search within the calling area to reduce battery consumption, and display when there is an incoming call without any discomfort in the search operation and display movement. Switching becomes natural. If it is not possible to determine that the user is in the call area by stopping the display of the information D1 to D4 regarding the call as a telephone, a blinking indicator for guiding the call area, for example, a light emitting diode lamp 14 is provided at the corner of the main body. Further, it is more preferable to provide the display unit 13 separately from the display unit 13 for displaying a symbol.

[0019]

As described above, the intermittent display is performed after a certain period of time while the telephone is on standby, so that the battery consumption is relatively small, a screen different from the telephone function is formed, and the call function is not excluded. It is possible to provide a telephone which can be used easily and has a surprising fashion feeling and which does not bore the user. Since the symbol information is selected at random, it is surprising that it moves intermittently, so that it is recognized that it is not only interesting but also in operation. The display of information about the call is stopped, and the symbol display is performed during the standby state, so that the call is not affected. The intermittent display of the symbol information is preferably at substantially the same cycle as the search within the calling area, and a blinking display device for guiding the calling area is provided separately from the display unit for displaying the symbol, and is mainly used. The screen produces a display screen that is not a telephone.
