A sheet conveyance device includes a sheet conveyance passage, a mounting plate, and a sheet detection sensor. The mounting plate is fixed to a recessed portion formed in the inner wall surface of the sheet conveyance passage at its one side it. The sheet detection sensor is fitted on the mounting plate. The sheet detection sensor has a sensor surface. The mounting plate has a mounting surface on which the sheet detection sensor is mounted and a first projection piece which projects from the mounting surface toward the sheet conveyance passage and which is grounded. The first projection piece is disposed upstream, in the sheet conveyance direction, of the sheet detection sensor on the mounting plate. The distance from the mounting surface to the distal end of the first projection piece is greater than the distance from the mounting surface to the sensor surface.

A sheet discharging apparatus includes a sheet discharge unit configured to discharge a sheet in a sheet discharge direction, a sheet supporting unit configured to support the sheet, a first charge eliminating unit arranged downstream of the sheet discharge unit in the sheet discharge direction and configured to eliminate electric charge from a surface of the sheet, a second charge eliminating unit arranged downstream of the first charge eliminating unit in the sheet discharge direction and configured to eliminate electric charge from a surface of the sheet. The first charge eliminating unit includes a plurality of first charge eliminating portions that are aligned with a first pitch in an intersecting direction intersecting the sheet discharge direction. The second charge eliminating unit includes a plurality of second charge eliminating portions that are aligned with a second pitch, that differs from the first pitch, in the intersecting direction.

A rotating portion, mandrel, or spool for use with an automatic tarping equipment attachment is provided. The rotating portion, mandrel, or spool can including a central portion, a first end portion, and a second end portion. The central portion can be constructed to enhance cylindrical dimensional conformity to aid in prevention of bunching or uneven weight distribution during rolling or unrolling of a tarpaulin therefrom, and the first end portion and the second end portion can be used to reinforce end portions of the central portion.

A sheet transport device includes a delivery roller and a transport route. The transport route includes an upper guide member and a lower guide member. The lower guide member includes a first guide rib, a first corrugation member, and a first elastic member. The first elastic member supports an end portion of the first corrugation member on a side of the delivery roller, such that the end portion protrudes ahead of the first guide rib toward the upper guide member, with respect to the other end portion. The upper guide member includes a second guide rib, a second corrugation member, and a second elastic member. The second elastic member supports an end portion of the second corrugation member on the side of the delivery roller, such that the end portion protrudes ahead of the second guide rib toward the lower guide member, with respect to the other end portion.

Provided is a sheet feeding device including: a cassette housing section; a sheet storage cassette; and a sheet feeding unit. The sheet storage cassette includes a cassette base which is configured to store recording media that have a sheet form, and can be inserted into and removed from the cassette housing section. The sheet feeding unit is provided in the cassette housing section, and is configured to feed the recording media to be stored in the sheet storage cassette. A pair of fixed-side rails that are made of metal and are attached to the cassette housing section. The cassette base is made of a resin. A pair of inner rails that are coupled to the pair of fixed-side rails so that the pair of inner rails are slidable are formed integrally with side surfaces of the cassette base.
