Abstract

PROBLEM TO BE SOLVED: To provide a portable telephone set that can directly exchange data with a portable telephone set placed nearby. SOLUTION: When a user operates a key instructing data display, a CPU 1 reads data from a RAM 3 and allows a display section 5 to display the data. The user views this display, selects data by using a key of the operation section, and operates a key instructing transfer. The CPU 1 outputs the data to an infrared ray transmitter-receiver 15. The infrared ray transmitter-receiver 15 modulates an infrared ray by data outputted from the CPU 1 and emits the modulated infrared ray. When receiving data transferred from other mobile phone or a personal computer, first the infrared ray transmitter-receiver 15 receives the infrared ray signal from the other mobile phone or the personal computer. The infrared ray transmitter-receiver 15 demodulates the data from the received infrared ray signal and outputs the data to the CPU 1. The CPU 1 writes the data to a specific data area of the RAM 3.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the embodiment. In this figure, reference numeral 1 denotes a CPU (Central Processing Unit) that controls each part of the circuit;
A ROM (read only memory) storing the program of U1 and a RAM (random access memory) 3 for storing data. The RAM 3 is backed up by a battery. Reference numeral 4 denotes an operation unit provided with a numeric keypad for inputting a telephone number, various function keys, and the like, and reference numeral 5 denotes a display unit using a liquid crystal display.

Reference numeral 6 denotes a communication unit having an antenna 7, which transmits transmission data on a carrier wave and transmits the data from the antenna 7, and also demodulates incoming data received via the antenna 7 and outputs the demodulated data to the CPU 1 or the voice processing unit 8. I do. Audio processing unit 8
Converts the audio signal output from the microphone 9 into digital data, further compresses and outputs it to the communication unit 6 as transmission data, converts the audio data output from the communication unit 6 into an analog audio signal, Output to Reference numeral 12 denotes a ring tone generation unit which forms a ring tone signal in accordance with an instruction from the CPU 1 and outputs the signal to the speaker 13. Reference numeral 15 denotes an infrared transmitting / receiving device, which modulates and emits an infrared ray by data supplied from the CPU 1, and
An infrared signal received from the outside is demodulated as reception data, and the reception data is output to the CPU 1.

Next, the operation of the portable telephone having the above configuration will be described. First, at the time of an incoming call, the communication unit 6 demodulates an incoming signal received via the antenna 7, and outputs the obtained incoming data to the CPU 1. The CPU 1 receives the incoming data, stores the telephone number of the caller in the RAM 3, and outputs a generation instruction to the ring tone generating unit 12. The ring tone generating unit 12 receives the generation instruction and outputs a ring tone signal to the speaker 13. As a result, the ring tone is
From 3 When the user of the mobile phone hears the ring tone and presses the receive button of the operation unit 4, the CPU 1 detects this, outputs a ring tone stop command to the ring tone generation unit 12, and outputs the voice processing unit 8 and the communication unit. 6 and outputs a line connection instruction. Thereafter, the line is connected to the caller, the sound signal of the microphone 9 is transmitted to the caller, and a sound based on the sound data from the caller is emitted from the speaker 10.

Next, when making a call, the user first inputs a telephone number using the numeric keypad of the operation unit 4, and then presses a call button. When a telephone number is input using the numeric keypad, the CPU 1 writes the telephone number into the RAM 3. Next, when the call button is pressed, the CPU 1
The telephone number stored in M3 is output to the communication unit 6. The communication unit 6 places the telephone number on a carrier wave and transmits the carrier number from the antenna 7. When a call based on the transmitted telephone number is sent to the destination telephone and the line connection of the destination telephone is established, the CPU
1 outputs a line connection instruction to the communication unit 6 and the voice processing unit 8, and thereafter, a telephone call using the microphone 9 and the speaker 10 is performed. The above processing is the same as the processing of a conventional mobile phone.

Next, the portable telephone can directly transfer the data in the RAM 3 to another nearby portable telephone or PC. Hereinafter, the processing will be described with reference to FIGS. First, a case where data in the RAM 3 is transferred to another mobile phone or the like will be described with reference to FIG. In this case, first, the user performs a key operation for instructing data display, for example, a key operation for instructing telephone directory display (step S1). In response to this key operation, the CPU
1 reads out the telephone number data of the telephone directory from the RAM 3,
It is displayed on the display unit 5 (step S2). The user looks at this display and selects the telephone number data to be transferred to another mobile phone using the keys of the operation unit, and then operates the key for instructing the transfer (step S3). The CPU 1 receives the key operation and outputs the telephone number data selected by the user to the infrared transceiver 15. The infrared transmitting / receiving device 15 modulates and emits an infrared ray according to the data output from the CPU 1 (step S5).

Next, a case of receiving data transferred from another portable telephone or PC will be described with reference to FIG. In this case, first, the infrared transmitting / receiving device 15 receives an infrared signal from another mobile phone or PC (step Sa1). The infrared transceiver 15 demodulates data from the received infrared signal and sends the demodulated data to the CPU 1.
Output to The CPU 1 supplies this data to the display unit 15 to display the data (step Sa2). The user checks the displayed data, and performs a key operation for instructing storage if the user intends to store the data (step Sa).
3). Upon receiving this key operation, the CPU 1 changes the received data to R
Write to the specific data area of AM3 (step Sa
4).

Next, a case where a telephone number received from another portable telephone or PC by infrared transmission is called from the RAM 3 and a call is transmitted will be described with reference to FIG. In this case, first, the user performs a key operation for instructing the calling of the specific data area (step Sb1). In response to the key operation, the CPU 1 reads out the telephone number data from the specific data area of the RAM 3 and displays it on the display unit 5 (step Sb2). After checking this display, the user presses the call button (step Sb3). When the call button is pressed, the telephone number data in the specific data area is sent to the communication unit 6 (Step Sb4). Next, the communication unit 6 transmits the telephone number data on a carrier wave (step Sb5).

In the above embodiment, data is transmitted and received using infrared rays. Alternatively, data may be directly transmitted and received by connecting to another portable telephone or the like using a cable. . The data transmitted and received via the infrared transmitting / receiving device 15 is not limited to a telephone number, but may be any data. For example, the following data can be considered. ○ Name-address-telephone number ○ User's own name-address-telephone number-other profile In this case, data exchange with the partner terminal can be used as a substitute for business card exchange. -Incoming melody data Either the data transmitted / downloaded from the distribution center or the data inputted by the user one note at a time may be used. -Image data Any data that has been distributed and downloaded from a distribution center, or a mobile phone with a small video (still) camera that has been imaged by the user himself may be used. -Music data As long as the mobile phone has a reproduction function such as an MP3 decoder, transmission and reception of music data may be performed.
