A medium-cutting device includes a medium-conveyance section to convey a medium in a medium-conveyance direction, a cutter to cut the medium conveyed by the medium-conveyance section, and a pushing part to push up a piece of the medium that is cut from the medium with the cutter.

A printing device includes: a platen unit; and a main body unit. The platen unit includes a platen roller configured to convey a printing medium. The main body unit includes: a printing head; and an attachment-detachment portion which the platen unit is attachable to and detachable from. The printing head is configured to nip the printing medium in cooperation with the platen roller to perform printing on the printing medium. When the platen unit is attached to the attachment-detachment portion, the main body unit and the platen unit are assembled as a single unit. When the platen unit is detached from the attachment-detachment portion, the main body unit and the platen unit are separated as separate units.

Disclosed is a method of cutting off self-adhesive linerless endless tape labels, using a cutter of a label printer, wherein the cutter comprises a transport roller, which is rotatable about an axis of rotation, and a blade unit that is linearly travelable in parallel with the axis of rotation of the transport roller and that has a cutting blade directed in the direction toward the transport roller, where tape labels pass between the transport roller and the blade unit, and are transported further step-wise in a motorized manner, by one label, and, between two consecutive further transport steps, the blade unit is linearly traveled in a motorized manner between a start position and a target position in order to cut off a label, such that the label is completely cut off and is held at the transport roller by the blade unit in the target position of the blade unit.

A paper discharge apparatus includes a discharge port through which paper is discharged, a transport unit that transports the paper to the discharge port, a sensor disposed adjacent to the discharge port, and a controller. The controller is configured to control the transport unit such that a downstream side end of the paper is exposed through the discharge port, determine based on an output from the sensor whether or not the downstream side end of the paper is being pulled, and control the transport unit so as to change a transport mode of the paper according to a determination of whether or not the downstream end of the paper is being pulled.

A cutting mechanism for a printing apparatus, the cutting mechanism includes: a cutter including a cutting blade and a blade receiving member, the cutter being configured to cut at least part of a printing medium with the cutting blade while the blade receiving member is receiving a force from the cutting blade; and a support member provided to suppress deformation of the blade receiving member, wherein the blade receiving member is adjacent to and fixed to the support member.

Disclosed is a printing device including a main body part including a body part configured to provide an internal space in which recording paper for printing certain information thereon is transferred and an opening or closing part configured to control opening or closing of the internal space, a printing part configured to print the certain information on the recording paper transferred in the internal space, and a recording paper separation part located on a downstream side of the printing part and configured to cut or cut off and separate recording paper on which particular information is printed by the printing part from the other recording paper. Here, the main body part includes a protruding part configured to prevent an adhesive attached to the surface opposite the adhesive surface from being accumulated by decreasing a contact area with the surface opposite the adhesive surface.

A printing apparatus according to an embodiment includes: a conveying device which conveys a record medium in a conveyance direction; a cutter which cuts out the record medium; a printing unit which prints an image on the record medium; a mark detector which detects a reference mark indicating a page start position of the record medium; a receiver which receives record medium type information; and a controller which, based on a content of the record medium type information, switches a cut position to be cut with the cutter between a first position being a position upstream in the conveyance direction by a predetermined one-page length from the page start position and a second position being a position shifted in the conveyance direction by a prescribed length from the first position.

A cutting device includes: a movable blade; a moving mechanism moving the movable blade and having a first mechanism portion movable between a first operating position and a first non-operating position and a second mechanism portion movable between a second operating position and a second non-operating position; a first detecting portion and a second detecting portion detecting positions of the first mechanism portion and the second mechanism portion; and a controller configured to perform: setting, when one of the first detecting portion and the second detecting portion detects abnormally, updated positions of the first operating position and the second operating position or the first non-operating position and the second non-operating position. The updated positions are set based on detection result of another of the first detecting portion and the second detecting portion and are new start points of movement of the first mechanism portion and the second mechanism portion.

A mobile printer includes: a roll body accommodating portion accommodating a roll body on which recording paper is wound; a print head performing printing on the recording paper; a transport unit pulling out the recording paper from the roll body and transporting the recording paper to the print head; a cutting unit cutting the recording paper; a power supply unit supplying a drive voltage signal to the print head, the transport unit, and the cutting unit; and a housing covering the roll body accommodating portion, the print head, the transport unit, the cutting unit, and the power supply unit, in which the power supply unit has a power receiving module receiving a signal based on a power supply voltage signal from an outside by a non-contact power supply, and the power receiving module is fixed to a power supply surface of the housing by an adhesive member.

A printing system for printing images onto a medium supplied as feed-stock, said system comprising a printer, a control computer and data inputting means, a printer head, a cutter, at least one rewinder and a taper; the print head for printing individual work-pieces onto the medium; the cutter for cutting the medium into individual work-pieces, and the at least one rewinder for rewinding the work-pieces into coreless-rolls, and the taper comprising a tape dispenser and printer for printing identifying data onto a piece of tape applied to fasten each coreless roll closed wherein the cutter and the printing of the tape is controlled by the control computer, wherein the cutter is configured to section the work-piece from the feedstock after it has started to be fed into the rewinder.
