摘要:
A printer comprises a recording portion with a thermal recording head for recording on a surface of a recording medium and a first conveying mechanism that conveys the recording medium. A thermal activation portion has a thermal activation head for heating another surface of the recording medium and a second conveying mechanism for conveying the recording medium. First and second discharge ports are disposed on a downstream side of the first and second conveying mechanisms, respectively. A pair of conveying rollers is arranged between the recording portion and the first discharge port and between the first discharge port and the thermal activation portion. The conveying rollers convey the recording medium from the recording portion to the first discharge port through normal rotation of the conveying rollers, change a conveyance course of the recording medium conveyed from the recording portion, and convey the recording medium to the thermal activation portion through reverse rotation of the conveying rollers.

A printing device has a platen roller, a print head for printing on a sheet material, and a sheet cutting device for cutting the sheet material on which printing has been performed. The sheet cutting device has a stationary blade and a movable blade for cutting the sheet material in a pressing contact state with respect to the stationary blade. A release mechanism is disposed in the stationary blade frame and is movable to first and second positions to release the stationary and movable blades. In the first position of the release mechanism, the blades are in the pressing contact state, the platen roller is in contact with the print head, and ends of a platen roller shaft of the platen roller are disposed adjacent to one end of respective elongated holes of a stationary blade frame supporting the stationary blades. In the second position of the release mechanism, the blades are moved out of the pressing contact state, the platen roller is in contact with the print head, and the ends of the platen roller shaft are disposed adjacent to the other end of the respective elongated holes of the stationary blade frame.

A thermal activation device includes a platen lock mechanism for locking a platen roller of a platen unit and a heating unit or printing unit into press contact with each other. The platen lock mechanism has a lock arm mounted to undergo rotation about a rotational axis, a shaft member provided in one of the platen unit and the lock arm, an engagement recess for engagingly receiving the shaft member and provided in the other of the platen unit and the lock arm, and an urging member for urging the lock arm in a direction for bringing the shaft member into engagement with the engagement recess. In a state in which the heating unit or printing unit is in press contact with the platen roller, a distance between the rotational axis of the lock arm and an axis of the shaft member is greater than a distance between the rotational axis of the lock arm and the rotational axis of the platen roller.

A stationary blade (31) is disposed on a downstream side in a transporting direction of a sheet material (5) with respect to a movable blade (41). A sheet cutting device (12) includes a stationary blade frame 33 supporting the stationary blade (31), a movable blade frame (43) supporting the movable blade (41), and a main frame (13) which movably supports the stationary blade frame (33) and to which the movable blade frame (43) is fixed. The stationary blade frame (33) is movably provided with the main frame (13) such that the stationary blade (31) is moved to a release position where a press contact state between the stationary blade (31) and the movable blade (41) is released while retaining a position of a printing device (1).

A thermal activation device includes a platen lock mechanism (19) for locking a platen roller (12) and a thermal activation head (11) into press contact with each other, the platen lock mechanism (19) including lock arms (32a and 32b) provided to be rotatable and engaged with a platen unit (18), and a compression coil spring (24) which urges the lock arms (32a and 32b) so as to bring the lock arms (32a and 32b) into engagement with the platen roller (18). The plate lock mechanism (19) includes lock pins (33) provided in the platen unit (18), and engagement grooves (37) which are provided in the lock arms (32a and 32b) and with which the lock pins (33) are engaged. Moreover, in the platen lock mechanism (19), in a state where the thermal activation head (11) is in press contact with the platen roller (12), an axis of the lock pins (33) is provided at a position farther than a position of a rotation center of the platen roller (12) with respect to a rotation center of the lock arms (32a and 32b).
摘要:
A printer comprises a frame having a pair of side walls spaced apart a given distance according to a given width size of a recording medium. A platen is supported between the pair of side walls and has a surface for supporting the recording medium. A printhead, operable in a printing position thereof to perform a printing operation on the recording medium, is supported between the side walls for tilting movement and displacement in forward/backward and rightward/leftward directions. A pressing body is supported by the frame for pressing the printhead into contact with the surface of the platen. When the printhead is in the printing position, the printhead is freely pivotable to permit automatic angular adjustment thereof following the surface of the platen so that the printhead can contact the surface of the platen with a uniform surface pressure.
