摘要： A control portion controls a change mechanism so as to pass through a third stretched form in switching a stretched form of a belt member from a second stretched form to a first stretched form. The first stretched form is a stretched form enabling a toner image to be transferred from a photosensitive drum to the belt member by positioning a transfer member at a first position and a separation roller at a second position. The second stretched form is a stretched form of separating each of the transfer member and the separation roller from a transfer surface toward an opposite side of the photosensitive drum. The third stretched form is a stretched form in which the transfer member is positioned at the first position, and the separation roller is positioned at a third position away from the transfer surface toward the opposite side of the photosensitive drum.

摘要： A photoacoustic imaging apparatus performs imaging of an optical absorber. The photoacoustic imaging apparatus includes a light source, a detector configured to detect an acoustic wave generated from the optical absorber that has absorbed energy of light emitted from the light source, and a signal processing unit configured to form an image of the optical absorber. The signal processing unit stores information indicating whether a rate of change in pressure of the acoustic wave detected by the detector is positive or negative before performing a waveform process on the acoustic wave.

摘要： A belt feeding device includes an endless belt, stretching rollers including a tension roller, a bearing member supporting the tension roller, a beating support member supporting the bearing member, an urging member urging the tension roller, a supporting member supporting the bearing supporting member, and a locking member. The locking member is movable between a first position where an engagement between the locking member and one of the bearing support member and the bearing member is released and the bearing member is permitted to move so as to apply the tension to the belt, and a second position where the locking member locks the bearing member by engaging with the bearing support member and the bearing member and the bearing member is restricted to move. The bearing member, the bearing support member, the urging member, and the locking member constitute a unit to be integrally dismountable from the supporting in the second position.
