This method has a great advantage in terms of convenience over the method of connecting connectors between electronic devices with a cable.

[0003]

However, since infrared light has high directivity, if the transmission / reception part of an electronic device is fixed, the communicable range between devices is limited, and the installation position is limited. There is a problem.

In order to solve such a problem, there is a device in which a transmission / reception port is formed separately and connected to a connector with an electronic device by a cable. However, in a laptop computer or an electronic notebook that emphasizes portability, a transmission / reception port is used. In many cases, the parts are built in and fixed to the main body, and at present, it is necessary to move the main body according to the communication range of each other's equipment, which is a cause of reduced convenience.

[0005]

[Means for Solving the Problems] An adapter having a structure attachable to and detachable from an infrared transmission / reception part of an electronic device such as a personal computer and a word processor and an optical transmission path capable of changing the direction of one end from the other end By attaching and receiving light, the communication direction of electronic equipment can be changed up and down and left and right.

[0006]
