IMAGE DEVICE, IMAGE READING DEVICE, AND IMAGE FORMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent occurrence of a dark place between light emission sources.SOLUTION: An image device 1 comprises: a state display unit 70 which includes a light source unit 71 having a plurality of LEDs (light emission sources) 74a, 74b, and displays information on a state of the image device by a lighting mode of the light source unit; one switching element 81 connected to the plurality of LEDs; and a control unit 60 for outputting a PWM pulse for operating lightning states of the plurality of LEDs to the switching element. The control unit makes the plurality of LEDs be lit by using only a duty ratio equal to or larger than a reference duty ratio which causes visually luminous regions of LEDs adjacent to each other to be seen as if the regions are connected.
