SIGNAL COLLECTING AND DISTRIBUTING DEVICE FOR PORTABLE TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a signal collecting and distributing device to realize optical transmission and reception between devices in contact with each other weight interference of light. SOLUTION: The signal collecting and distributing device for portable terminal can be disposed in contact with a portable terminal only by attaching the terminal to the device, and aligning for optical communications can be completed. Usually, when optical communication is performed in a contact state of a portable terminal to the collecting and distributing device, the original light is reflected to interfere with adjacent light caused by the intensity of light. Therefore, a label 51 having pin holes formed by printing is adhered to the outside of a filter 52 which transmits light.
