An accessory device is for an electronic marking device. The accessory device has a connection device for releasably connecting to an electronic marking device, and the accessory device has a stop for limiting movement of a document transversely to a printhead of a connected electronic marking device. A deflecting mechanism deflects the document, and the stop and the deflecting mechanism are arranged on different sides of the printhead of the connected electronic marking device. An electronic marking device includes a printhead, a movement detector, and a controller. The controller is connected to the movement detector and to the printhead and is configured to actuate the printhead in order to print a document when movement of the electronic marking device over the document is detected by the movement detector. The electronic marking device has a stop for limiting movement of the document transversely to the printhead.

A position detection apparatus configured to detect a position on a movement surface of a mounted object having the position detection apparatus mounted thereon, includes a moved amount detector configured to detect an amount of movement on the movement surface; a posture detector configured to detect at least a posture of the mounted object on the movement surface; and a position calculator configured to calculate the position of the mounted object, based on the amount of movement and the posture.

According to one embodiment, a mobile printer includes a first housing, a second housing, a hinge, and a print head. The first housing has a first surface on which a printing medium can be disposed. The second housing faces the first surface. The hinge connects the first housing and the second housing and permits the first and second housings to rotate relative to each other. The print head is provided in the second housing and is configured to print an image by discharging on to the print medium when the print medium is on the first surface between the first and second housings.

A printing apparatus including: a first roller mechanism including: a first shaft part having a first gear; and a first roller in which the first shaft part is inserted; and a second roller mechanism including: a movable holder configured to be moved in directions coming close to and being separated from a printing medium by a displacement mechanism; a second shaft part which is rotatably supported on the movable holder and having a second gear; a second roller in which the second shaft part is inserted, tiltable with respect to a shaft center of the second shaft part, and having an engaging groove recessed in an inner peripheral surface of an intermediate part of the second roller in a shaft center direction; and a protrusion protruding from an outer peripheral surface of the second shaft part and engaged with the engaging groove of the second roller.

A printer that performs printing on a medium while being manually moved relative to the medium, includes a job acquisition unit that acquires a print job in which a movement direction of the printer as seen from the printer is designated, a print head that performs printing on the medium based on the print job while the printer is moved, and a direction notification unit that notifies a user of a designated direction as the movement direction of the printer designated by the print job before the movement of the printer is started.

A steel stamping tool includes a base and a cover removably mounted to the top of the base. Multiple stamps are accommodated in an accommodating space form between the base and the cover. The cover includes an extension extending from one of two ends of the cover, and at least one passage is defined vertically through the extension. The cover is removed from the base and the one stamp is picked from the accommodation space and inserted through the at least one passage. The stamp in the passage is not radially rotatable. A work end of the stamp is located in the concaved space and contacts an object. By striking a striking end of the stamp that is exposed on the top face of the extension, the work end of the stamp embosses the object.
