Abstract
A communication device capable of improving power saving is provided. A communication device (1) includes a communication port (10); communication monitoring sections (18, 22) for controlling information communication using the communication port, a status indicating section (12) having one or more status indicators, a status indicator driving section (20) for controlling a drive signal which detects a communication status from the communication monitoring sections and is supplied to the status indicating section on the basis of the communication status, and a lighting control section (24) for detecting the communication status from the communication monitoring sections and outputting a control signal to the status indicator driving section if the communication status changes from a first status to a second status. The status indicator driving section controls the drive signal so as to turn off the status indicators when the control signal is outputted from the lighting control section.
