Abstract: A sheet cassette includes a housing, multiple cassettes stacked and provided in the housing, and a rotary cam. The cassettes store a recording sheet. The rotary cam includes multiple pins provided at opposite positions across the axis of rotation of the rotary cam. Adjacent cassettes are offset relative to each other in an offset direction. First receiving parts for receiving the pins are provided one in each of the adjacent cassettes at a first end thereof in the offset direction. The rotary cam rotates with at least one of the pins being in at least one of the first receiving parts of the adjacent cassettes to move the cassettes as connected.

Abstract: A printing apparatus includes a printer, a baseplate, a jacket, and a container. The printer is configured to perform printing on a recording sheet. The baseplate holds the printer. The jacket is attached to a first surface of the baseplate, and is configured to hold an information terminal. The container is attached to a second surface of the baseplate facing away from the first surface, and is configured to store the recording sheet.

Abstract: A printer for printing information on a recording medium includes a guide that guides the recording medium being fed and includes multiple holes, a sensor for detecting the recording medium, and a board that includes multiple terminals. The sensor is mounted on at least one of the terminals such that the sensor is exposed through one of the holes.

Abstract: A printer includes a printer body (110) including a recording-paper holder (111) that holds rolled recording paper (100) and includes a holder guide (112) for guiding the recording paper (100), a platen roller (140), a print head (130) attached to the printer body (110), and a lower guide (160) that is disposed to face the holder guide (112) such that a conveying path for guiding the recording paper (100) is formed between the lower guide (160) and the holder guide (112).

Abstract: A printer includes a print head; a platen roller; a frame, to which the print head or the platen roller is attached, that includes a frame body, a sidewall that is perpendicularly bent from the frame body with respect to a longitudinal direction of the platen roller, and a back surface member that is bent from the frame body in parallel to the longitudinal direction of the platen roller, the back surface member including an end portion and a support portion provided to support the sidewall from an inner side and an outer side of the sidewall, respectively, the sidewall being supported by the back surface member while being interposed between the end portion the support portion of the back surface member.

Abstract: A printer includes a print head and a platen roller. The platen roller includes multiple bearings provided one at each longitudinal end of the platen roller, a roller positioned between the bearings, and multiple flanges of which one is positioned between the roller and one of the bearings and the other is positioned between the roller and the other of the bearings in the longitudinal direction of the platen roller. The flanges have a diameter greater than the diameter of the bearings and the diameter of the roller.

Abstract: A printer includes a body, a lid, a hook, and an engaging part. The body includes a holder configured to accommodate recording paper. The lid is attached to the body to be opened and closed relative to the body. The hook is attached to one of the body and the lid. The engaging part is attached to the other of the body and the lid. The engaging part is accommodated in a recess formed in the hook when the lid is closed relative to the body.

Abstract: A printer includes a holder configured to house rolled recording paper, a cover that is attached to the holder to be openable and closable relative to the holder, and a contact part that is attached to the cover and configured to contact the recording paper. The contact part is configured such that the contact part substantially point-contacts the recording paper, and positions on the contact part contacting the recording paper change as the recording paper is unrolled.

Abstract: A printer includes a body configured to accommodate recording paper, a lid attached to the body to be openable and closable relative to the body, a pressing part on the lid, a platen roller attached to the lid, a movable shaft in the body, a spring that urges the movable shaft, and a lever configured to support bearings of the platen roller with the lid being closed. The movable shaft is provided at a position corresponding to the pressing part to be movable in a longitudinal direction of the movable shaft, and is pressed by the pressing part to generate a spring force in the spring during closure of the lid.
