Abstract: A thermal printer with enhanced cutting performance includes a thermal head for performing printing on successively supplied recording sheets, and a platen roller for feeding the recording sheets. A cutter for cutting the recording sheets has a fixed blade and a movable blade. A main body unit supports the fixed blade, and a cover unit supports the movable blade and is removable with respect to the main body unit. A pinion gear meshes with a rack constructed integrally with the movable blade to move the movable blade. The main body unit supports the pinion gear, and the cover unit supports only the movable blade and the platen roller.

Abstract: In order to place both ends of a platen roller in bearing portions of a frame to perform accurate printing on a recording sheet with improved operability, a thermal printer comprises: a pair of concave portions (10d) provided to a frame to receive both end portions of a roller shaft (13e) of a platen roller (13) when a cover (8) is in a closed state; a pair of lock arms for automatically engaging the roller shaft (13e) of the platen roller (13) with the concave portions along with an operation of closing the cover (8); and a connection mechanism (30) for turnably connecting the platen roller (13) to the cover (8), and is characterized in that an axis of rotation of the platen roller (13) in the connection mechanism (30) is contained in a plane passing through a midpoint between the pair of concave portions (10d) to be vertical to an axial direction of the concave portions (10d) and is arranged parallel to the cover (8).

Abstract: A continuous sheet processing apparatus has a main body portion that accommodates a roll formed of a wound continuous sheet, a door portion movable to opened and closed positions for opening and closing an inlet of the main body portion through which the roll is introduced into the accommodating portion, and a processing portion that processes the continuous sheet drawn out from the roll. A guide portion is movable between a first position in which the guide portion extends parallel to the center axis of the roll and guides the path of the drawn-out continuous sheet so that the drawing-out angle thereof is an acute angle, and a second position in which the guide portion extends transverse to the center axis of the roll. A guide portion actuator moves the guide portion to the first position in conjunction with movement of the door portion to the closed position and moves the guide portion to the second position in conjunction with movement of the door portion to the open position.

Abstract: To provide a thermal printer in which cutting performance with respect to a recording sheet is enhanced, a thermal printer (1) includes a thermal head (34) for performing printing on successively supplied recording sheets, a platen roller (65) for feeding the recording sheets, and a cutter for cutting the recording sheets. The thermal printer includes: a fixed blade (30) and a movable blade (10) that constitutes the cutter; a main body unit (4) which supports the fixed blade (30); a cover unit (3) which is removable with respect to the main body unit (4) and which supports the movable blade (10); and a pinion gear (42) which meshes with a rack (44) constructed integrally with the movable blade (10) to move the movable blade (10), wherein the main body unit (4) supports the pinion gear (42), and the cover unit (3) supports only the movable blade (10) and the platen roller (65).
