Abstract:
1. An infrared communication adapter, comprising: a portable telephone side communication interface for carrying out a serial data transmission by connecting with an external communication interface provided in a portable telephone, in accordance with a serial data transmission protocol of the portable telephone; an infrared communication interface for carrying out a data communication with an external equipment having an infrared communication interface in accordance with an infrared communication protocol; a data processing section for carrying out a data process to transmit a data supplied from one communication interface of the communication interfaces, to another of the communication interfaces; wherein the data processing section includes-- a protocol conversion unit for analyzing a communication protocol of a data supplying side communication interface and for converting the analyzed communication protocol into a communication protocol corresponding to a data receiving side communication interface, and a data conversion unit for converting a serial data supplied from the portable telephone side communication interface, into a data which can be transmitted in accordance with the infrared communication protocol, to transmit the data to the infrared communication interface, and for converting a data supplied from the infrared communication interface, into a serial data which can be processed by the portable telephone, to transmit the serial data to the portable telephone side communication interface; a storing section for storing a data; and an operation section for being operated by a user, wherein the data processing section includes-- a first judging unit for judging whether the portable telephone is connected to the adapter or not, a second judging unit for judging an operating state in accordance with an operation time or the number of operations of the operation section, and a control section for controlling the adapter so as to carry out one process selected from a first process for reading a data from the storing section in accordance with each judging result of the first and second judging units to transmit the read data to the external equipment through the infrared communication interface, a second process for receiving the transmitted data from the external equipment through the infrared communication interface to store the received data in the storing unit, a third process for reading a call number data registered to the connected portable telephone, to transmit the read call number data to the external equipment through the infrared communication interface as an electronic visiting card data, and a fourth process for receiving the electronic visiting card data for the external equipment through the infrared communication interface and extracting a data which can be registered to the portable telephone, from the electronic visiting card data, to register the extracted data to the portable telephone.
