An image reading device includes: a reading unit in which light receiving elements are arranged in a line along a second direction; and a light source control section that controls emission of the light source members, the light source control section performing control such that light is emitted in a cycle order of the first, second, and third colors on the basis of a reference signal which is output at a preset time interval, and to make a time of emission of the light with the first color close to a time of start of emission of the light with the second color and to make a time of emission of the light with the third color close to a time of end of emission of the light with the second color.

Signal processing device, image reading device, image forming apparatus, information processing apparatus, and non-transitory computer readable medium

The present invention provides a cooling system including: a cold air generator which supplies cold air into a case of an apparatus; a wireless temperature sensor which is provided near at least one module constituting the apparatus and sends temperature data as a radio signal; a transmitter/receiver which sends a radio signal having a predetermined frequency to the temperature sensor and receives a radio signal from the temperature sensor; and a controller which controls an operation of the cold air generator on the basis of a radio signal received by the transmitter/receiver.

Cooling system and image forming apparatus with cooling system

An image forming apparatus having an image forming part that forms an image on a recording medium measures, downstream of the image forming part in a transport path of the recording medium, speckles on the recording medium, and generates measured speckle data that represents speckles measured; stores the generated measured speckle data in a memory part, further measures, upstream of the image forming part in a transport path of a recording medium, the speckles of the recording medium; determines whether speckle data representing speckles analogous to speckles measured upstream of the image forming part is stored in the memory part, and, in the case where the decision result is affirmative, recognizes that the recording medium for which the speckles have been measured is a recording medium on which an image has been formed on it previous to having speckles measured upstream of the image forming part.

Image forming apparatus

An image forming apparatus with an image forming part and a fixing part for fixing images on a recording medium measures, downstream of the fixing part in a transport path, speckles on a recording medium, and generates measured speckle data representing the measured speckles; stores measured speckle data with standard speckle data representing speckles on a recording medium that has not undergone a fixing process; further measures, upstream of the image forming part, measures speckles on a recording medium; and when the stored standard speckle data is the most analogous to speckles measured for the second time, applies corrections in order to compensate for the lengthening of the recording medium by a fixing process to document images formed thereon, and when the stored measured speckle data is the most analogous to speckles measured for the second time, does not perform the corrections in order to compensate for the lengthening.
