Abstract

PURPOSE:To release limitation attended with miniaturization of a portable telephone set and limitation attended with the connection with an on-vehicle stationary section by adopting the constitution such that a key entry section controlling the portable telephone set section and the on-vehicle stationary section is separated as a remote controller section. CONSTITUTION:When the user uses a key pad 15 of a remote control section 11 to apply key entry, the key entry information is encoded by a transmission data generation LSI 13, converted into infrared ray information by using a power battery 14 and the infrared ray radiates in air. The infrared ray is received by a data reception section 115 at an on-vehicle stationary section 112 and decoded by a microcomputer 114. The microcomputer 114 sends a received data sent from a remote control section 11 to a microcomputer 19. The microcomputer 19 decodes the content to send an instruction to a radio section 18 and a microcomputer 114 and the content sent from the remote control section 11 is displayed on a key entry section 110.

In this case, the wireless section 33 and the wireless section 38 are controlled by the control section 34 and the control section 37, respectively.

In this manner, it is possible to make a call using the key input section of the telephone even in the above-mentioned conventional mobile telephone, in-vehicle fixed section, or car telephone device.

Incidentally, such mobile phone devices are always required to be smaller and lighter for convenience in handling.

Problems to be Solved by the Invention However, in the conventional mobile phone device described above, since the phone itself has a key input section, when a telephone with a key display section or a mobile phone is downsized, the key input section is proportionally reduced. The input section also has to be made smaller, which makes it difficult for the user to perform key input operations, especially when mounted on a vehicle.

The present invention solves these conventional problems,
The object of the present invention is to provide a mobile phone device that is easy for a user to operate even when installed in a vehicle.

Means for Solving the Problems In order to achieve the above object, the present invention provides a key input unit, a transmission data generation unit that generates transmission data in response to key input, and an infrared ray transmitter that generates data corresponding to the transmission data. The remote controller includes an infrared data transmitting section that transmits data, and an in-vehicle fixed section that includes an infrared data receiving section and a data decoding section that decodes the received infrared data.

In the second invention, a key input unit, an input display unit that displays a key input result, a transmission data generation unit that generates transmission data in response to a key input, and transmits data corresponding to the transmission data by infrared rays. The present invention includes a remote control unit including an infrared data transmitting unit, and an in-vehicle fixed unit including an infrared data receiving unit and a data decoding unit that decodes the received infrared data.

In the third invention, a remote control unit includes a key input unit, a transmission data generation unit that generates transmission data in response to the key input, and an infrared data transmission unit that transmits data corresponding to the transmission data by infrared rays, and an infrared data reception unit. The mobile phone includes a data decoding unit that decodes received infrared data.

Effects The present invention has the following effects due to the above structure. That is, since the remote control unit can control the in-vehicle fixed part of the mobile phone or the mobile phone, the remote control unit can be placed in a position where it is easy for the user to operate, and key input is facilitated.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, reference numeral 11 denotes a remote control section as a wireless remote control transmitter, which includes a keypad 15 (key input section) and a transmission data generation LS 113 (transmission data generation section) that generates transmission data in response to key inputs on the keypad 15. ), a data transmitting section 12 having an infrared light emitting section that transmits data according to the transmitted data using infrared rays, and a power source battery 14.

Further, 16 is a mobile phone section, which includes an antenna 17, a wireless section 18, a microcomputer 19, and a key input display section 11.
0 and a keypad 111. Further, 112 is an in-vehicle fixed unit, which includes a wireless unit 113, a microcomputer 114 (including a data decoding unit), and a data receiving unit 115 having, for example, a PIN photodiode.

Next, the operation of the above embodiment will be explained. In FIG. 1, when the user performs a key input using the keypad 15 of the remote controller 11, the key input information is encoded by the transmission data generation LS 113, and the power source battery 113 encodes the key input information.
4, it is converted into infrared information and radiated into the air.

This infrared rays are received by the data receiving section 115 in the vehicle-mounted fixed section 112, and decoded (data decoded) by the microcomputer 114. The microcomputer 114 transmits data transmitted and received from the remote controller 11 to the microcomputer 19. The microcomputer 19 decodes the contents and transmits the command to the wireless section 18 and the microcomputer 114.
The content transmitted from the remote control unit 11 is input to the key input unit 110.
to be displayed.

As described above, according to the above embodiment, the key input section for controlling the mobile phone section 16 and the vehicle-mounted fixing section 112 is connected to the remote control section 1.
1 has the advantage of being freed from restrictions associated with miniaturization of mobile phones and restrictions associated with connection with vehicle-mounted fixed parts.

FIG. 2 is a schematic block diagram of another embodiment. In this embodiment, a key input display section 216 for displaying key input results is provided in the remote control section 21.

In FIG. 2, the same reference numerals as in FIG. 1 indicate the same components as in FIG. This embodiment has the advantage that the user can confirm key inputs on the input display section 216 of the remote control section 21.
