A coarse crusher includes a coarsely crushing unit configured to coarsely crush a sheet piece having an elongated shape, a hopper configured to feed the sheet piece to the coarsely crushing unit through a feed opening, and a posture adjuster configured to adjust posture of the sheet piece. The hopper includes two guide plates facing each other with the feed opening therebetween and configured to guide the sheet piece to the coarsely crushing unit and two coupling plates coupling the two guide plates. The posture adjuster includes a protrusion disposed on at least one of the coupling plates and protruding toward an inner side of the hopper. The posture adjuster is configured to come in contact with the sheet piece being coarsely crushed to adjust the posture of a portion of the sheet piece that is remote from the coarsely crushing unit.

A web transportation apparatus includes a mesh belt configured to be rotated to transport a web formed of a dry deposited material containing fibers and a striking member configured to strike a return section of the mesh belt to remove the material attached to the mesh belt. The striking member includes a striking bar and a striking lever. The striking bar is reciprocated to strike the mesh belt.

A hopper includes a receiving member having a guide surface that guides a non-flat strip-shaped sheet and a posture adjusting unit that adjusts a posture of the falling sheet and sends it to the guide surface, and a discharge unit that discharges the sheet. The posture adjusting unit may have a posture adjusting surface continuous with the guide surface and bent from the guide surface so as to form a ridge line at a boundary portion with the guide surface.

Provided are a shredder assuring greater freedom in designing a feedstock supplier that supplies sheets, and a sheet manufacturing apparatus. The shredder has a feedstock supplier having a supply opening through which a sheet is supplied; and a shredding device configured to shred the sheet supplied from the feedstock supplier. The shredding device includes a rotary cutter that rotates on a first axis, and a circulating cutter that moves in an endless path and cuts the sheet in conjunction with the rotary cutter. The circulating cutter includes a conveyor configured to convey the sheet from the feedstock supplier to the rotary cutter.

Shredder and sheet manufacturing apparatus

There is provided a transporting section configured to transport a recording medium, a recording head configured to record an image on the recording medium, a carriage movable and holding the recording head, a first guide member guiding movement of the carriage, a second guide member guiding the movement of the carriage, a first movable member movable along with the carriage, a second movable member disposed away from the first movable member and movable along with the carriage, and a driving section configured to drive the carriage between a position where the recording head records the image onto the recording medium and a position where the recording head is separate from a path over which the transporting section transports the recording medium by moving the first movable member and the second movable member. The driving section moves the first movable member and the second movable member in synchronization.
