摘要： In a cap mode where a cap member covers a nozzle surface, a controller controls a second movement mechanism so that the cap member is disposed opposite to the nozzle surface. In an ejection recovery mode where ink is ejected from a plurality of nozzles and the ink adhered to the nozzle surface is wiped off by a wiping member, the controller controls a first movement mechanism and the second movement mechanism so that the nozzle surface, a wiping tray and the cap member are arranged downward in this order.

摘要： An image reading device is provided. The image reading device suppresses uneven intensity of light emitted on a subject, by disposing a diffusion plate between the subject and a plurality of luminescence portions, and an image forming device that includes this image reading device. The image reading device includes an illumination portion that irradiates light onto a subject. The illumination portion includes: a plurality of LED's disposed at predetermined intervals in a main scanning direction; and an elliptical diffuser plate that is disposed between the subject and the plurality of LED's and diffuses light emitted by the plurality of LED's in a higher diffusion rate in the main scanning direction than in a sub-scanning direction.

摘要： The present invention is aimed at providing an image reading device that suppresses generation of a so-called edge shadow while suppressing uneven intensity of light emitted onto an original. A color copy machine 1 includes an illumination portion 347a that irradiates an original G with light. The illumination portion 347a includes a plurality of LEDs 501 disposed at predetermined intervals in a main scanning direction, an elliptical diffuser plate 507 that is disposed between the plurality of LEDs 501 and the original G and causes the light emitted by the plurality of LEDs 501 to diffuse, and a second reflection mirror 541B that reflects light, which is a portion of the light diffused by the elliptical diffuser plate 507 and not directly irradiated onto the original G, so as to irradiate the light onto the original G.
