Abstract: An electrical connector of an image forming apparatus exposes outward from a bottom surface of the image forming apparatus. An electrical connector of a sheet feeder protrudes from a top surface of the sheet feeder. The sheet feeder has a slider configured to be horizontally movable, while holding the electrical connector of the sheet feeder, between a connecting position at which the electrical connectors of the sheet feeder and image forming apparatus are connected and a disconnecting position at which the electrical connectors are disconnected. A locking member having a locking engaged part is fixed to the image forming apparatus. When the slider is moved to the connecting position, a locking engaging part of the slider engages the locking engaged part of the locking member so that the locking member and the slider are locked such that they cannot be separated vertically from each other.

Abstract: A toner case includes a case main body, first and second agitators, and a transmitting mechanism. The case main body is configured to store a toner. The first and second agitators are configured to rotate and to agitate the toner in the case main body. A transmitting mechanism is configured to transmit rotation to the first and second agitators. The transmitting mechanism stops transmission of the rotation to the second agitator while the transmitting mechanism continues the transmission of the rotation to the first agitator, when driving torque of the second agitator is equal to or more than a first set value.

Abstract: A sheet feeder includes: a sheet feed roller holding member that holds a pick-up roller capable of coming into contact with and away from a top surface of a sheet, supports the pick-up roller rotatably, and pivotally moves while urging the pick-up roller toward contact with the top surface of the sheet; a restricting member that restricts pivotal movement of the sheet feed roller holding member, resulting in restriction of movement of the pick-up roller toward the contact with the top surface of the sheet; and a restriction cancelling portion that is provided in a sheet feed cassette and abuts against the restricting member to apply to the restricting member a pressing force from the sheet feed cassette, thus cancelling the restriction of the restricting member.

Abstract: A pair of slide rails supports a unit on inner side surfaces of a housing in a drawable manner. Each of the pair of slide rails includes a fixed rail, an intermediate rail, and a moving rail. The fixed rail is fixed on the inner side surface along a draw-in direction and a draw-out direction. The intermediate rail is engaged with the fixed rail in a slidable manner. The moving rail is fixed on the unit and engaged with the intermediate rail in a slidable manner. The intermediate rail includes a base part and an upper edge part and a lower edge part respectively bent inward from an upper end and a lower end of the base part. The base part has an extended part formed in such a manner that the lower edge part is protruded from a front end portion of the base part in the draw-out direction.

Abstract: A positioning structure includes a positioning aiding member attached to a horizontal beam of a sheet feeder and having a positioning hole formed at an opposed portion thereof opposed to the horizontal beam. The positioning aiding member has a guide part that, when an image forming apparatus is installed onto a top of the sheet feeder, guides a horizontal beam of the image forming apparatus such that a positioning hole formed in a lower surface of the horizontal beam of the image forming apparatus approaches a first positioning pin coupled with the positioning aiding member as viewed in an extending direction of the horizontal beam of the sheet feeder.

Abstract: A sheet feeding device includes a cassette storage part, a sheet feed cassette, a pickup roller, a feed roller, a retard roller, a retaining member, and a pushing mechanism. The pushing mechanism pushes the retaining member so that the retard roller is pushed to contact with the feed roller. The pushing mechanism includes a pushing member that contacts and pushes the retaining member, and a biasing member that biases the pushing member. In a plane perpendicular to a rotation shaft of the retard roller, a pushing direction of the pushing member in a push contact position against the retaining member forms an angle of 45 degrees or less, with a straight line connecting the center of the rotation shaft of the retard roller and the center of a rotation shaft of the feed roller.

Abstract: 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.

Abstract: The slide rail includes an outer rail, an inner rail and a drawing mechanism. The outer rail is fixed on an inner surface of a housing. The inner rail is fixed to a unit, engaged with the outer rail and moves along the outer rail. The drawing mechanism is supported by the outer rail, coupled to the inner rail at a draw-in start position and draws in the inner rail to a draw-in end position along a draw-in direction. The inner rail includes a coupling pin and a protrusion. The coupling pin is provided on one end portion in the draw-in direction, and configured to be engaged with the drawing mechanism. The protrusion is provided on the other end portion in the draw-in direction, and protrudes toward the outer rail.

Abstract: A sheet feeding cassette (21) includes a body part (31), a placement plate (33) disposed on a bottom plate (31a) of the body part (31), a shaft (61) extending along a width direction, a lift plate (35) configured to be turned around the shaft (61) to lift and lower a downstream end portion of the placement plate (33), and a pair of side cursors (37F, 37R). Both end portions of the shaft (61) are rotatably supported by the body part (41), outside in the width direction of the side cursors (37F, 37R) disposed at the most separate position. The side cursors (37F, 37R) each has an abutment wall (71F, 71R) abutting on a side surface of the sheet and a recess (79) externally fitted to the shaft (61) from above, and the recess (79) slides on the shaft (61) when the side cursors (37F, 37R) move in the width direction.
