Abstract: Provided is a small-sized device for measuring an oxidation-reduction potential, whereby an oxidation-reduction current and an oxidation-reduction potential can be measured by reducing noise even when a signal from a solution being measured is small. A device for measuring an oxidation-reduction potential is provided with a substrate (10), a working electrode (15) mounted on a surface of the substrate (10), and a bipolar transistor (21) for amplifying the output of the working electrode (15) also provided on the surface of the substrate (10), and the signal amplified by the bipolar transistor (21) is inputted to a processing circuit (18).

Abstract: 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.

Abstract: 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.

Abstract: 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.
