Abstract: An image forming apparatus includes: an image reading mechanism configured to read an image from a document; an image forming mechanism configured to print the image read by the image reading mechanism on a recording sheet; and an image inspection mechanism configured to read the image printed on the recording sheet in the image forming mechanism. The image reading mechanism and the image inspection mechanism each include: a light source configured to irradiate a reading target with light; and a solid-state image sensing device on which reflected light from the reading target is made incident, and configured to perform photoelectric conversion operation. Light emitting members forming the light sources of the image reading mechanism and the image inspection mechanism have the same spectral characteristics.

Abstract: Disclosed is a discrimination device that may serve to discriminate a type of a recording medium and may include: a housing unit provided with an opening so as to face a conveyance path on which the recording medium is conveyed; and a light emitting unit and a light receiving unit that are accommodated in the housing unit. The light emitting unit may be capable of emitting light toward the recording medium disposed so as to face the opening. The light receiving unit may be capable of receiving light reflected from the recording medium. The housing unit may include a shutter that allows switching between an opened state where the opening is opened and a closed state where the opening is closed.

Abstract: A light guide for use in an image reading apparatus. The light guide extends in a predetermined direction. The light guide comprises an emitting surface, through which light rays entering the light guide are emitted, and a reflecting surface configured to reflect the light rays to the emitting surface. A cross-sectional surface of the light guide, which is a sectional surface of the light guide along a plane orthogonal to the predetermined direction in which the light guide extends, has a shape including a combination of an ellipse and a parabola. The parabola on the cross-sectional surface of the light guide defines the reflecting surface. A focal point of the parabola is located on a first focal point of the ellipse that is closer to the reflecting surface.

Abstract: A sheet distinguishing device that determines sheet type and includes a light emitter, a light receiver, a calculator 53, and a determiner 52. The light emitter irradiates a sheet with light at discrete wavelengths. The light receiver receives light from the sheet. The calculator 53 obtains an intensity of light for each of the discrete wavelengths from the light received, and calculates a characteristic value with respect to a wavelength distribution of light intensity, based on the intensities obtained. The determiner 52 determines whether the sheet is a first type or a second type by using the characteristic value.

Abstract: An image reading apparatus includes a light source, a light receiving unit, and an optical system. The light receiving unit includes a plurality of light receiving elements. The optical system includes a plurality of optical components for splitting the light reflected from the object to be read, and guiding the split light to each of the plurality of light receiving elements. The plurality of optical components include a splitting component that splits the light reflected from the object to be read in a direction corresponding to a main direction, and a common component provided with a common portion. The common portion has an optically acting area causing a common effect on the tight split by the splitting component. A cross sectional shape of the optically acting area orthogonal to a direction corresponding to the main direction is the same shape along the direction corresponding to the main direction.

Abstract: An information processing apparatus includes an acquirer and a display information generator. The acquirer is configured to acquire acquisition information and environment information of an image forming apparatus. The acquisition information includes at least one of job information, error information, time information, or machine information of the image forming apparatus. The display information generator is configured to generate display information to be displayed on a display by associating the acquisition information acquired by the acquirer out of the job information, error information, time information, or machine information with the environment information.

Abstract: An image reading apparatus includes a light source that emits light in a main scanning direction to a subject to be read, a light receiving unit that receives light reflected by the subject to be read, and an optical system that images the light reflected by the subject to be read and guides the light to the light receiving unit. The optical system includes a reflector mirror that reflects the light reflected by the subject to be read, and an optical element that is disposed adjacent to the reflector mirror and images the light reflected by the subject to be read. The optical element is held by the reflector mirror.
