A medium conveying apparatus includes a medium tray, a pair of side guides to regulate a width direction of a medium, and a housing on which the medium tray is located and including a conveyance path capable of conveying the medium placed on the medium tray. The pair of side guides are located on the medium tray so that outer ends of the pair of side guides can be positioned from an inside of the medium tray to an outside of a maximum width of the medium tray. The conveyance path can convey a medium having a width of an inside of the pair of side guides even when the outer ends of the pair of side guides are positioned outside the maximum width of the medium tray.

A sheet conveying device includes a tray, a device body having a conveying route of a sheet and supporting the tray, a side guide supported by the tray to be movable in a first direction intersecting with a conveying direction of the sheet and contacting an end portion in the first direction of the sheet placed on the tray, a cover rotatable with respect to the device body and covering the conveying route, and a lock lever locking the cover to the device body and provided in a position overlapping the side guide in a second direction intersecting with the conveying direction and the first direction. The lock lever is rotatable between a lock position where the cover is locked and a release position where the cover is released. The side guide includes a first notched portion facing a rotation track of the lock lever with a gap.

A sheet product dispenser for dispensing sheet product from a roll of sheet product is provided. An example sheet product dispenser includes a housing defining an interior space for receiving a first roll of sheet product (170a, 170b) therein, a mandrel (150a, 150b) positioned within the interior space, and a spindle (100) positioned over at least a portion of the mandrel and configured to support the first roll of sheet product for rotation about the mandrel. The spindle comprises abase portion (102) and a nose portion (104) configured to translate relative to one another along a longitudinal axis of the mandrel (150a, 150b). At least a portion of the spindle is configured to translate relative to the mandrel from a first configuration to a second configuration to cause a remainder of the first roll of sheet product (170a, 170b) to deform and enable movement of a dispensing door (186) to enable access to a second roll of sheet product.

A recording device includes a recording unit, a discharge roller unit, a medium receiving tray, a motor serving as a power source of the discharge roller, a power transmission unit that is configured to switch between a power transmission state in which power of the motor is transmitted from the motor to the medium receiving tray, and a power non-transmission state in which the power of the motor is not transmitted from the motor to the medium receiving tray, and a restriction unit that is configured to switch between a restriction state in which the restriction unit restricts displacement of the medium receiving tray when the power transmission unit is in the power non-transmission state, and a non-restriction state in which the restriction unit does not restrict the displacement of the medium receiving tray when the power transmission unit is in the power transmission state.

A transportation portion includes an apparatus body, a cover, first and second path formation portions, and a movement portion. The apparatus body has a transportation path including a downward path and an upward path having portions located at the same level in the Z direction. The cover covers and uncovers the transportation path. The first path formation portion is movable to a first position and to a second position. The second path formation portion defines the upward path and defines the downward path with the first path formation portion. The movement portion moves the first path formation portion in response to opening or closing of the cover. The first path formation portion is positioned in a movement area during a closed state. The movement portion moves the first path formation portion to the second position when the cover is opened and to the first position when the cover is closed.

In a printing medium accommodating apparatus, a printing medium discharged from a discharge port of a printing apparatus is stacked. The printing medium accommodating apparatus includes: a receiving member configured to receive a printing medium discharged from the discharge port; and a holding member having a holding portion configured to hold one end of the receiving member, the holding member being capable of being connected with a first attachment unit attached to the printing apparatus, the holding member being configured to be capable of transitioning from a first state where the holding member is connected with the first attachment unit to a second state where the holding member is separated from the first attachment unit.

A printing medium accommodating apparatus is a printing medium accommodating apparatus in which to stack a printing medium discharged from a discharge port of a printing apparatus. This apparatus includes: a receiving member configured to receive a printing medium discharged from the discharge port; a holding member configured to hold one end of the receiving member; and a turning member configured to turn the holding member, and includes a first attachment unit capable of attaching the turning member to an insertion slot provided in the printing apparatus.

A sheet feeding device includes a feeding roller pair, a first guide, a door including a second guide and rotatable between a first direction and a second direction opposite to the first direction through first to third positions, a damping mechanism, and an engaging portion including an elastic member. A first resisting force is set so that moment acting around a shaft by a self-weight of the door is larger than the first resisting force of the damping mechanism when the door is positioned between the second position and the third position. A resultant force of the first resisting force of the damping mechanism and a second resisting force of the elastic portion is set so that the moment acting around the shaft by the self-weight of the door is larger than the resultant force when the door is positioned between the second position and the third position.

The conveyance guide unit is provided with a guide member, a supporting frame, and an external cover. The guide member guides a sheet, which is discharged from a sheet discharge port of the image forming apparatus or from a sheet discharge port of a relay conveyance device installed in the image forming apparatus, to the sheet carrying-in port of a post-processing device. The supporting frame supports the guide member. The external cover is fixed to the supporting frame; the external cover covers an upper part of the guide member and side parts of the guide member in a traverse direction of a sheet conveyance path, which is perpendicular to a sheet conveyance direction. The external cover has an upper surface serving as an extension part of a discharge tray part of the post-processing device, the extension part being extended downstream, in a sheet discharge direction.

A sheet feeding apparatus includes a sheet conveyance roller, a retard roller to contact the conveyance roller and separate sheets one by one, a drive input shaft, a retard shaft, and a joint to connect the retard shaft with the drive input shaft and transmit rotary drive force of the drive input shaft to the retard shaft. A first angle formed between a line passing through a first engagement position and the drive input shaft and a line passing through a second engagement position and the retard shaft center is within a range of 80 degrees or greater and 100 degrees or smaller, and a second angle formed between a line passing through the drive input shaft and a first pin axis and a line passing through the retard shaft and a second pin axis is within a range of 50 degrees or greater and 70 degrees or smaller.
