Abstract: A device for measuring a length of a recoding material, includes: a rotating body that rotates in contact with a recording material which is transported; a length measuring unit that measures a length of the recording material based on a rotation of the rotating unit; a detecting unit that detects at least one of a rotation and an oblique advance of the recording material; and a correcting unit that corrects a value measured by the length measuring unit based on an output of the detecting unit.

Abstract: A measuring device of a length of a recording material includes: a rotary unit that rotates while coming into contact with the recording material; a pulse signal output unit that outputs a pulse signal in response to a rotation angle of the rotary unit; first and second detection units that detect the recording material; and a calculation unit that calculates a length of the recording material. The calculation unit calculates a piece of the length of the recording material corresponding to a time below pulse interval of the pulse signal and then calculates the total length in the transport direction of the recording material.

Abstract: An apparatus for measuring a length of a recording material, includes: a rotating member that rotates while contacting a conveyed recording material; a detecting section that detects a rotation amount of the rotating member; an information obtaining section that obtains at least one of information of an image formed on the recording material and information of the recording material; and a calculating section that calculates a length of the recording material in a direction of the conveyance, based on an output from the detecting section and the information obtained by the information obtaining section.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The present invention provides an IC-tag-attached sheet wherein an IC tag is attached in a margin of a sheet for image formation.

Abstract: A medicine management system comprising: a first IC tag given to any one of a patient's medicine record, a prescription, a medicine bag, or a consultation ticket; the first IC tag containing the prescription information including data corresponding to a medicine name; a second IC tag given to a holding unit holding a medicine, the second IC tag containing the medicine information including data for identifying a medicine; a reading part that reads prescription information from the second IC tag; and a determination part that determines on the basis of the read respective information whether the medicines are in agreement.

Abstract: An IC tag includes: a communication unit which exchanges data with an external device; a storing unit which stores data; a detecting unit which detects a change in environment surrounding the IC tag or a change in a state of the IC tag; and a deleting unit which deletes the data stored in the storing unit when the detecting unit detects a change in environment surrounding the IC tag or a change in a state of the IC tag.
