Embodiments include a carton feeding system for feeding a plurality of cartons to a conveyor track, comprising a plurality of feeding devices, where each feeding device comprises a pick-up head with a plurality of vacuum cups, and an erecting finger pivotally suspended at the pick-up head, where the pick-up head has a pick-up position (P1) in which the holding plane of the pick-up head is positioned parallel to the folded carton blank that is to be picked up, and an insertion position (P2) in which the erecting finger is pivoted with respect to the holding plane of the pick-up head in such a way that the carton is opened, and where at least two cartons are inserted simultaneously into the conveyor track.

An image forming apparatus includes an image forming device, a transfer section, a plurality of sheet feed trays, processing circuitry, and a detector. The image forming device forms an image. The transfer section transfers the image onto a sheet. The plurality of sheet feed trays store sheets and supply the sheets from sheet feed ports to the transfer section. The processing circuitry switches sheet feeding from one sheet feed tray in use to another sheet feed tray when the sheets run out in the one sheet feed tray in use. The detector detects a remaining amount of sheets in the one sheet feed tray in use. The processing circuitry enlarges spacing between images formed by the image forming device when the remaining amount of sheets in the one sheet feed tray in use is equal to or less than a threshold value, based on a detection result of the detector.

A sheet feeding sub tray is detachably attachable to a sheet loading stand of a sheet conveying device that includes a setting reference part on one end side of the sheet loading stand in a sheet width direction. The sheet feeding sub tray includes a small-size setting reference part disposed at a position closer to a center of the sheet loading stand in the sheet width direction than the setting reference part in a state in which the sheet feeding sub tray is installed to the sheet loading stand.

A conveyor, including: receiving trays; a conveyance mechanism; and a support supporting the trays, wherein at least one tray except a lowermost tray is supported so as to be selectively positioned at one of a receiving position and an upper position, wherein at least one lower tray except an uppermost tray includes a protruding portion attached to a tray body so as to be selectively positioned at one of a protruding position and a retracted position, and wherein the conveyor includes a force transmitting mechanism for effectuating at least one of (a) a retracting movement of the protruding portion of one of the at least one lower tray from the protruding position to the retracted position caused by an upward movement of an adjacent upper tray disposed just above and immediately adjacent to the one of the at least one lower tray from the receiving position to the upper position.

A recording medium processing apparatus includes a housing that accommodates a processing unit, which is capable of processing a recording medium, and that has an internal space a part of which is open; an internal stacker that is disposed in the internal space and that allows the recording medium to be stacked thereon; a light source that is disposed in a part of the internal stacker and that emits a light beam toward a predetermined position on the internal stacker, the light beam notifying a user of a state in which the recording medium is or is not stacked on the internal stacker; and a reflection member that is disposed in a part of the internal stacker and that reflects the light beam from the light source laterally outward from the internal stacker.

A tray includes: a first accommodating part configured to accommodate a rolled first sheet medium; and a second accommodating part disposed side by side with respect to the first accommodating part in a first direction and having a support surface configured to support a second sheet medium. The second accommodating part is configured to accommodate a plurality of sheets of the second sheet medium in a stacked state. The second accommodating part is configured to be either in a first state where a length of the support surface in the first direction is a first length, or in a second state where the length of the support surface in the first direction is a second length shorter than the first length.

In an example, a print media transport apparatus comprises a plurality of pallets having a self-propulsion mechanism, and being to support print media. The pallets may circulate on an endless track comprising a printing zone, a descending zone and an ascending zone. A controller may control the self-propulsion mechanisms of the pallets such that a pallet on the descending zone is at least partially supported by another pallet which is ahead on the track, and a pallet on the ascending zone is at least partially driven by pallet which follows on the track.

A printing device that can continuously print on a plurality of recording media even if a user is not beside the printing device over a long period of time is provided. The printing device includes a tray storing container (10) that installs a plurality of trays (20) on which mount media (100) are mounted, and a transfer section (30) that takes out one tray (20) among the plurality of trays (20) from the tray storing container (10), and transfers the same to a printing region (R1) facing a surface for discharging ink in a head (40).
