Printer apparatus

A printer apparatus comprising:

• a printer unit that includes a thermal head, a first module including a motor, and a second module including a platen roller and a rotating body;
• a printed paper roll shaft that rolls up printed paper that is drawn from a heat sensitive paper roll and is carried through the printer unit;
• a first chassis that includes a heat sensitive paper roll accommodating portion that accommodates the heat sensitive paper roll, and a first mount portion to which the first module is mounted;
• a second chassis that is configured to rotate with respect to the first chassis to be opened/closed, the second chassis including a second mount portion to which the second module is mounted, a rotation transmitting mechanism that transmits a rotation of the rotating body to the printed paper roll shaft, and a printed paper roll accommodating portion that accommodates a printed paper roll that is created by rolling the printed paper around the printed paper roll shaft;
• wherein when the second chassis is closed, the heat sensitive paper roll accommodating portion is closed, the second module is coupled to the first module, the platen roller is rotated by the motor, the rotating body is rotated by the motor, and the printed paper roll shaft is rotated by the motor via the rotating body and the rotation transmitting mechanism.

• a second chassis that is configured to be attached to and detached from the first chassis, the second chassis including a second mount portion to which the second module is mounted, a shaft mount portion to which the printed paper shaft is mounted, a rotation transmitting mechanism that transmits a rotation of the rotating body to the printed paper roll shaft, a heat sensitive paper roll supporting portion that is arranged at a lower surface side of the second chassis and is configured to support the heat sensitive paper roll, and a printed paper roll accommodating portion that is arranged at an upper surface side of the second chassis and is configured to accommodate a printed paper roll that is created by rolling the printed paper around the printed paper roll shaft;
• wherein heat sensitive paper that is drawn from the heat sensitive paper roll is arranged to pass a portion of the second module and the upper surface side of the second chassis, and an edge portion of the heat sensitive paper is arranged to be wound around the printed paper roll shaft;
• and
• when the second chassis is attached to the first chassis, the second module is coupled to the first module, the platen roller is rotated by the motor, the rotating body is rotated by the motor, and the printed paper roll shaft is rotated by the motor via the rotating body and the rotation transmitting mechanism.

A printer apparatus comprising:

• a printer unit that performs printing on a label that is attached to tape shaped release paper of a label paper roll;
• a chassis that is configured to be opened/closed through rotation;
• a printed label separating unit that is configured to separate a printed label from the tape shaped release paper;
• and
• a tape shaped release paper roll shaft configured to roll up the tape shaped release paper from which the printed label is separated;
• wherein a rotation of a motor of the printer unit is transmitted to the tape shaped release paper roll shaft, and tape shaped release paper roll shaft is rotated by the rotation of the motor.
