    • PROBLEM TO BE SOLVED: To provide an automatic door device capable of ensuring safety without deteriorating the transparency and design performance of a transparent door body. SOLUTION: A door body 3 of the automatic door device 1 comprises a pair of transparent light guide plates and a light source provided on the end surface of each of the light guide plates. A display portion 40a composed of a plurality of recesses with a reflecting surface reflecting light emitted from the light source to a front side is formed at one of the light guide plates. A display portion 40b composed of a plurality of recesses is formed at the other light guide plate. A control section provided in a drive unit 2 causes the light source corresponding to the light guide plate having the display portion 40b to emit light while the door body is moved in an opening direction to make the display portion 40b to display light by the emission of the light during moved na direction in which the door body 3 is opened, and causes the light source corresponding to the light guide plate having the display portion 40a to emit light while the door body 3 is moved in a closing direction to cause the display portion 40a to display light by the emission of the light.
