摘要： A paper type determination device of the invention drives plural light emitting points different from one another and having sequentially increasing distances from a reference point to emit light in such a manner that each is identified for irradiating one surface of a sheet of paper subjected to determination. A photodetection device set at a specific detection field of view having the center at the reference point is disposed on the other surface side of the sheet of paper, and it receives light having passed through the sheet of paper from the respective light emitting points at positions on inside and outside of the detection field of view to detect intensity of light for each light emitting point. A diffusing characteristic of the sheet of paper is obtained on the basis of the intensity of light from each light emitting point detected by the photodetection device, and a paper type is determined on the basis of the diffusing characteristic.

摘要： An image forming apparatus includes: a sheet tray; an image forming unit that forms an image on a recording sheet; a sheet transporting path that allows a transportation of the recording sheet fed from the sheet tray to the image forming unit; and a sheet detecting unit that detects a passage of a rear end, with respect to a direction in which the recording sheet is transported, of the recording sheet along the sheet transporting path. The transportation of the recording sheet is temporarily stopped at the time of, or after a predetermined time from when the rear end is detected by the sheet detecting unit. The transportation of the recording sheet is resumed on the basis of data on a size of the transported recording sheet and a timing of image formation by the image forming unit.

During a period from when the detecting unit detects the forward edge of the sheet until the detecting unit detects the rear edge, the sheet is decelerated from a first conveying speed to a second conveying speed. After the detecting unit detects the rear edge of the sheet, the conveying of the sheet is stopped and punching processing to the sheet is executed when the conveying is stopped.

摘要： An effective image area can be properly corrected in accordance with the quantity of light from an irradiation unit by selecting, as the effective image area, pixels having light quantities more than or equal to a threshold value that allows accurate acquisition of a surface image of a recording medium, on the basis of a light quantity distribution of the light from the irradiation unit. This reduces the influence of mounting accuracy of the irradiation unit, and allows the recording medium to be identified accurately.
