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: 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 option device for an electrical appliance of the invention is provided with a filter for purifying exhaust air from the electrical appliance, and an electric fan, wherein the air flow resistance in an external air inlet port formed independently of a suction port for sucking exhaust air from the electrical appliance is adjustable. According to this configuration, it is easy to secure balance between the exhaust air flow rate of the electrical appliance and the suction force by the electric fan without variably controlling the rotational speed of the electric fan.

Abstract: A toner supply device includes a toner storage, a supply opening, a toner conveyer, a toner supply opening, and an air passage. The toner storage stores toner. Through the supply opening, the toner is supplied to a developing device. The toner conveyer includes an area of space different from an area of space of the toner storage. The toner conveyer conveys the toner stored in the toner storage to supply the toner from the supply opening to the developing device. Through the toner supply opening, the toner is supplied from the toner storage to the toner conveyer. The air passage is at a position different from the toner supply opening. The air passage connects the toner storage to the toner conveyer so as to allow air flowing through the supply opening into the toner conveyer to be supplied to the toner storage through the air passage.

Abstract: An electrical machine includes an exhaust fan and an exhaust port on which an optional device is mounted. The optional device includes a duct, an electric fan, and an air flow sensor. Through the duct, an exhaust gas from the exhaust port is guided. The electric fan draws in the exhaust gas flowing through the duct and discharges the exhaust gas into an atmosphere. The air flow sensor detects presence or absence of the exhaust gas flowing from the electrical machine. The air flow sensor includes an air path partitioned from an inside of the duct by a partition wall. The air path includes an exhaust gas and an exit port. The exhaust gas intake port includes an opening facing the exhaust gas. The exit port communicates with the atmosphere at a position outside the duct.
