Abstract: A medium carrying device includes a first pair of rollers that forms a nip part and carries a medium, the nip part being defined as an area where the rollers contact each other applying a pressure to other, a guide part that guides the medium to the first pair of rollers, and a medium detection member that includes a tip end part and a pivoting fulcrum and that is pivoted around the pivoting fulcrum by the medium as the medium moves along the guide part. In a case of being viewed from a roller axial direction of the first pair of rollers, the tip end part passes the nip part when the medium detection member pivots around the pivoting fulcrum as a center.

Abstract: A sheet storage cassette can include a sheet supporting board and a restriction guide. The sheet supporting board can support at least one sheet thereon. The restriction guide can be arranged on the sheet supporting board and include a sheet holding surface that is substantially perpendicular to the sheet support board. The restriction guide can further include a mark indicated part at an upper side thereof, where the mark indicated part can extend at least partly along a plane that intersects a plane of the holding surface and can indicate a maximum storage capacity level of the sheet storage cassette.

Abstract: A medium feeding cassette includes a cassette main body, a cassette extension member mounted to the cassette main body so as to be movable with respect to the cassette main body, and a locking mechanism configured to lock the cassette extension member at a predetermined position with respect to the cassette main body according to a size of the medium. The locking mechanism includes a locking member and a first locking groove that engage each other so as to lock the cassette extension member in the predetermined position. The locking member moves in a direction to release locking of the cassette extension member when a force is applied to the cassette extension member in a direction to retract the cassette extension member into the cassette main body.

Abstract: A media-loaded device includes a main body and a guide unit. The main body, in which media are stackable, has a first engaging member. The guide unit is movable relative to the main body and has a disengaging member. The disengaging member has a second engaging member that engages with the first engaging member. The second engaging member is disengaged from the first engaging member by an external force applied to the disengaging member in a stacking direction of the media.

Abstract: A medium transport device includes a transport unit for transporting a medium, and a guide member disposed on a downstream side of the transport unit in a direction that the medium is transported. The guide member includes a first portion corresponding to the transport unit and a second portion having a shape different from that of the first portion.

Abstract: A medium feeding device includes: a sheet holding unit, which holds a sheet and is pivotally attached to a device main unit so that the sheet holding unit is pivotal between open and closed positions; a sheet feeding roller that is located close to the sheet holding unit and that feeds the sheet to the inside of the device main unit; and a driving shaft that is located on an axis that is different from a rotation shaft for the sheet feeding roller and that drives the rotation shaft.

Abstract: A medium supplying apparatus is assembled to an image forming apparatus. A medium tray supports a medium thereon, and is pivotal about a first axis and extends from the first axis. The medium tray has a guide path that extends in the first radial direction. A feeder frame has a pickup roller rotatably mounted to the feeder frame, and is pivotal about a second axis substantially parallel to the first axis. The medium tray and the feeder frame are drivingly coupled via a link. When the medium tray pivots to its open position or closed position, the link transmits the motion of the medium tray to the feeder frame in such a way that the feeder frame drivingly pivots to its open position or closed position.

Abstract: An image forming apparatus includes a driving roller for transporting a medium; a follower roller disposed to face the driving roller for transporting the medium; a guide member for guiding the medium to change a transport direction thereof by an angle greater than 30°; and a rotational member disposed to be freely rotatable at a position corresponding to a side edge of the medium. Accordingly, after the driving roller and the follower roller transport the medium, when the medium contacts with the guide member, side edges of the medium contact with the guide member at an angle smaller than that of a center portion of the medium contacting with the guide member.
