Printer having a selector associated with a carriage for actuating a plurality of switching mechanisms

A printer, comprising:

• a print head operable to print on a printable medium;
• a carriage, which reciprocately carries the print head;
• a printing region provided within a reciprocating range of the carriage, in which the print head is allowed to perform printing;
• a first non-printing region provided within the reciprocating range of the carriage, in which the print head is not allowed to perform printing, the first non-printing region provided adjacent to one side of the printing region;
• a second non-printing region provided within the reciprocating range of the carriage, in which the print head is not allowed to perform printing, the second non-printing region provided adjacent to the other side of the printing region;
• a plurality of switching mechanisms, each switching mechanism being movable between a first position and a second position;
• and
• a selector associated with the carriage so as to move the selector to actuate at least one of the switching mechanisms to the second position when the carriage has moved to the first non-printing region, and to actuate the at least one of the switching mechanisms to the first position when the carriage has moved to the second non-printing region.

A method of controlling a printer, the printer including:

• a paper transporting path, which guides paper,
• a print head, which performs printing on the paper placed in the paper transporting path,
• a carriage, which carries the print head and reciprocates in a direction orthogonal to the paper transporting path,
• a printing region provided within a reciprocating range of the carriage, in which the print head is allowed to perform printing,
• a first non-printing region provided within the reciprocating range of the carriage, in which the print head is not allowed to perform printing, the first non-printing region provided adjacent to one side of the printing region,
• a second non-printing region provided within the reciprocating range of the carriage, in which the print head is not allowed to perform printing, the second non-printing region provided adjacent to the other side of the printing region,
• a plurality of switching mechanisms, each switching mechanism being movable between a first position and a second position, and
• a selector configured for operation by the carriage so as to move the selector to actuate at least one of the switching mechanisms to the second position when the carriage has moved to the first non-printing region, and to actuate the at least one of the switching mechanisms to the first position when the carriage has moved to the second non-printing region,
• wherein:
• the selector is movable at least among a first selector position, a second selector position and a third selector position,
• the first non-printing region includes at least a first switching position and a second switching position, and the second non-printing region includes at least a first restoration position and a second restoration position,
• the selector is placed at either one of the first, the second or the third selector positions to actuate the at least one switching mechanism to the second position when the carriage is placed at either one of the first switching position or the second switching position, and
• the selector is placed at either one of the first, the second or the third selector positions to actuate the at least one switching mechanism to the first position, when the carriage is placed at either one of the first restoration position or the second restoration position,
• the printer further comprising a pair of paper feed rollers operable to transport the paper in the paper transporting path, wherein the switching mechanisms include a paper feed roller actuating mechanism which opens or closes a space between the paper feed rollers,
• an MICR head which reads at least one magnetic character pre-printed on the paper, and
• a retainer, which retains the paper on the MICR head, wherein the switching mechanisms include an MICR actuating mechanism which opens or closes a space between the MICR head and the retainer,
• wherein:
• the paper feed roller actuating mechanism is actuated at one of the first and the second switching positions, and at one of the first and the second restoration positions,
• the MICR actuating mechanism is actuated at the other one of the first and the second switching positions, and at the other one of the first and the second restoration positions,
• the paper feed roller actuating mechanism is actuated so as to close the space between the paper feed rollers at the first switching position, and so as to open the space at the second restoration position,
• the MICR actuating mechanism is actuated so as to close the space between the MICR head and the retainer at the second switching position, and so as to open the space at the first restoration position,
• the second switching position is placed outwardly from the first switching position in the first non-printing region, and
• the second restoration position is placed outwardly from the first retraction position in the second non-printing region,
• wherein the method comprises:
• detecting an insertion of the paper into the paper transporting path;
• moving the carriage to the second switching position via the first switching position;
• reading the magnetic character on the paper by the MICR head while transporting the paper by the paper feed rollers;
• moving the carriage to the first restoration position;
• and
• performing printing on the paper by the print head while transporting the paper by the paper feed roller.
