Publication number: 20200290384Abstract: An inkjet recording device includes: an image former; an image reader including a line sensor and an optical unit; and a conveyor. The line sensor has imaging elements, and detects incident light from a surface of a recording medium over an imaging range corresponding to arrangement of the imaging elements in a width direction intersecting a relative movement direction in which the recording medium and/or the image reader is relatively moved, thereby performing one-dimensional imaging along the width direction. The optical unit removes a high-frequency-side component that is a spatial structure equal to or higher than a predetermined cutoff frequency from spatial distribution of the incident light from the imaging range and guides the incident light to the line sensor. The cutoff frequency for the high-frequency-side component is determined to be lower in the width direction than the relative movement direction.Type: ApplicationFiled: March 8, 2017Publication date: September 17, 2020Inventors: Masakazu DATE, Toshiyuki Mizutani
