Abstract: Disclosed is a recording apparatus including a recording head that performs recording with respect to a medium at a prescribed distance, a contact section that is capable of being in contact with the medium, a carriage that changes a relative location between the medium and the contact section, and an ultrasonic sensor that is capable of sensing an ultrasonic wave which is generated in a case where the medium is in contact with the contact section. The carriage changes the relative location such that a relative velocity between the medium and the contact section is over a prescribed value (transport velocity of the medium), and the ultrasonic sensor is capable of detecting a state of the medium by sensing the ultrasonic wave.

Abstract: An optical scanning device includes a reflected-light passing unit having a passing region through which a portion of reflected light that is the scanning light reflected by the medium passes. An outer peripheral contour line of the passing region includes a contour curve configured with a set of points where coordinates in a direction orthogonal to a scanning direction are uniquely determined for the coordinates in the scanning direction. The contour curve renders a curve protruded toward the passing region. When a region in contact with the contour curve in the passing region is divided into a plurality of quadrilateral minute regions having equivalent areas and extending from the contour curve to a predetermined coordinate position in the scanning direction and are continuously arranged in the orthogonal direction, widths of the minute regions in the scanning direction are different for each location in the orthogonal direction.

Abstract: Provided is technology improving the efficiency (productivity) of a sheet manufacturing apparatus. A sheet manufacturing apparatus 100 manufactures sheets S by heating with heaters 81 and 82 a mixture (second web W2) of resin and fiber produced by defibrating feedstock MA. The heaters 81 and 82 each have a first roller 171, a second roller 172 that holds the second web W2 with the first roller 171, and a moving mechanism 190. The moving mechanism 190 can switch the first roller 171 and second roller 172 to a position holding the second web W2, and a first roller 171 and second roller 172 are separated and do not hold the second web W2. The heaters 81 and 82 are configured as units that can removably installed to the sheet manufacturing apparatus 100.
