A medium supply device is provided that includes a single sheet paper accommodating unit at which media are stacked and placed, and a feeding roller configured to feed the media by rotating in contact with a top surface of the placed media. The feeding roller includes a contact portion configured to contact the single sheet paper and a non-contact portion configured to not contact the single sheet paper in a rotational direction, and a plurality of the contact portions and the non-contact portions are provided in a first direction that is an extending direction of a rotation axis of the feeding roller, and the contact portions adjacent to each other in the first direction are out of phase in the rotational direction.

Apparatus for making a cardboard strip for packaging includes a store for a stack of cardboard sheets, a gripping mechanism for picking up a sheet from the stack and positioning another sheet on a first support for the application of adhesive, and a transfer mechanism for transferring the first sheet to rest on the second support with an end portion having the adhesive projecting towards the store and towards a third support. The third support is disposable in a raised position to raise an end portion of a second sheet coming from the store and in a lowered position to lower the end portion of the second sheet and position it at the end portion of the first sheet. A pressor presses the two superposed end portions of the two sheets to fix the end portions to one another to form a cardboard strip.

A printing device includes a first ejector that ejects a recording medium to an exterior, a second ejector that enhances a rigidity of the recording medium more than by the first ejector, and ejects the recording medium to the exterior, and an ejector selector that selects either the first ejector or the second ejector.

In a copier, printer, or similar device, paper is loaded in large quantities. To separate a top sheet of a stack of sheets from the next adjacent sheet, a dam is used, which is an element having an inclined surface in the path of the top sheet. This invention addresses devices with variably compliant separation strips, preferably a thermoplastic polyurethane elastomer such as Pellethane®, that are part of the dam, so that the leading edge of a media sheet will strike the inclined surface of the separation strip. By adjusting the compliance of the separation strip, different weights of media may be accommodated while minimizing the multi-feeds that may cause jamming of the device.

A thermal-transfer printing apparatus includes a roll-paper-supplying unit that rotates an image-receiving paper roll and unwinds and winds a roll type of first image-receiving paper, and a print unit that includes a thermal head for heating a thermal transfer sheet and that forms an image by transferring a color material from the thermal transfer sheet to the first image-receiving paper. With the image-receiving paper roll removed, a reverse unit that reverses a sheet type of second image-receiving paper is mountable in a region in which the image-receiving paper roll used to be contained. The print unit forms the image on the first image-receiving paper in a first printing mode in which the image-receiving paper roll is contained in the region, and the print unit forms an image on both surfaces of the second image-receiving paper in a second printing mode in which the reverse unit is mounted on the region.

The apparatus (100) for realising a cardboard strip for packaging comprises: a store (M), for a stack (P) of cardboard sheets (C); gripping means (4), for picking up a cardboard sheet (F1) from the stack (P) and for positioning the second cardboard sheet (F1) on the first support (1) for the application of adhesive material; transfer means (6), for transferring the first cardboard sheet (F1) towards the second support (2), so that the first cardboard sheet (F1) is rested on the second support (2) with an end portion (E) thereof with the adhesive material projecting towards the store (M) and towards a third support (3).

The third support (3) is activatable into a raised configuration (S), to raise an end portion of a second cardboard sheet coming from the store and into a lowered configuration (A) so as to lower the end portion (E2) of the second sheet (F2) and position it at the end portion of the first sheet (F1). Pressor means (7) are activated transversally to the two sheets (F1, F2) so as to press the two superposed end portions (E, E2) of the two sheets (F1, F2) in order to fix the end portions (E, E2) to one another to form a cardboard strip (NC).

A thermal-transfer printing apparatus includes a roll-paper-supplying unit that rotates an image-receiving paper roll and unwinds and winds a roll type of first image-receiving paper, and a print unit that includes a thermal head for heating a thermal transfer sheet and that forms an image by transferring a color material from the thermal transfer sheet to the first image-receiving paper. With the image-receiving paper roll removed, a reverse unit that reverses a sheet type of second image-receiving paper is mountable in a region in which the image-receiving paper roll used to be contained. The print unit forms the image on the first image-receiving paper in a first printing mode in which the image-receiving paper roll is contained in the region, and the print unit forms an image on both surfaces of the second image-receiving paper in a second printing mode in which the reverse unit is mounted on the region.

A paper compartment in which roll paper can be held has an opening positioned along the second axial end of the roll paper and a wall positioned along the first axial end of the roll paper in the axial direction. The paper loading member can be removably installed in the paper compartment through the opening. The paper loading member has a flange and a roll support member that projects from the flange and is inserted into the paper. When roll paper is held in the paper compartment, the paper loading member is installed in the paper compartment with a first side of the flange contacting the first axial end of the paper, and the roll support member is inserted into the roll paper. When the paper loading member is installed in the paper compartment, the first side of the flange faces the opening.

A medium cassette of the present disclosure is a medium cassette configured to be inserted and removed with respect to an apparatus main body and capable of selectively accommodating any recording medium of a roll medium having a continuous medium which is wound in a roll shape and a single sheet medium.

A sheet conveying device includes a detector configured to detect an attitude of a conveyance target medium, a corrector configured to perform a correcting operation based on a detection result of the detector, and circuitry configured to calculate an angular displacement correction amount and a lateral displacement correction amount of the conveyance target medium, cause the corrector to perform the correcting operation in a direction perpendicular to a sheet conveying direction, based on the lateral displacement correction amount, after the corrector grips the conveyance target medium, and cause the corrector to rotate by the angular displacement correction amount of the conveyance target medium before the corrector grips the conveyance target medium and to perform the correcting operation in a direction of rotation of the conveyance target medium, based on the angular displacement correction amount, after the corrector grips the conveyance target medium.
