Abstract: A reading apparatus configured to read a plurality of colorimetric patches in different colors formed on a paper sheet and trigger patches formed so as to correspond to the colorimetric patches includes: a colorimeter configured to read the colorimetric patches; a trigger sensor configured to read the trigger patches; and a controller configured to control a reading region, wherein the controller has a colorimetry region determination mode in which the reading region is determined and a colorimetry adjustment mode in which the reading region is controlled, and in the colorimetry region determination mode, after the reading regions are set to states where the reading regions are gradually shifted in a reading direction, the reading results for the colorimetric patches are collected and thereafter, a region for which a state consistent with a characteristic of the colorimetric patch has been obtained as the reading result is determined as the reading region.

Abstract: A serial tandem image forming system is described which is capable of inhibiting both the degradation of image quality and the reduction of the productivity. This system consists mainly of the control units of upstream and downstream apparatuses. When a preceding sheet differs from the subsequent sheet in sheet type, a control unit for controlling the image forming system has the subsequent sheet stand by at a paper stop roller of the upstream apparatus, and performs the operation of switching the operating states of the upstream and downstream apparatuses in accordance with the sheet type of the subsequent sheet. Also, the control unit predicts the timing of finishing the switching of the operating state, and then re-starts the conveyance of the subsequent sheet, in advance of finishing the switching of the operating state, by controlling the paper stop roller on the basis of the predicted finishing timing.

Abstract: An image reading apparatus and an image forming system are provided which can reduce the influence of magnification error, detect patches in correct positions, and save the sheets required for adjusting an image. The image reading apparatus makes use of an image scanner which reads patches printed on a sheet P, a spectral colorimeter which colorimetrically measures the patches read by the image scanner, and is provided with a timing compensation unit which compensates the colorimetric measurement timing with which colorimetric operation of the spectral colorimeter is triggered based on the positional information of the patches read by the image scanner, and an image correction unit which corrects the color information of the patches read by the image scanner based on the colorimetric values of the patches colorimetrically measured by the spectral colorimeter.

Abstract: An image-forming apparatus contains a control portion, a thermopile sensor, a temperature sensor, a fan, a heater, a guide plate temperature detection sensor, an external air temperature detection sensor, a fixing temperature detection sensor and the color sensor. The control portion calculates estimated sheet temperature of the conveying sheet using information such as guide plate temperature, external air temperature, fixing temperature and paper weight. The control portion controls the fan or the heater to drive so that sensor temperature of the thermopile sensor approaches the estimated sheet temperature of the sheet. The control portion controls the thermopile sensor to carry out a measurement of the temperature of the sheet when the sensor temperature falls within a set range in relation to the estimated sheet temperature.
