PURPOSE:To provide a compact light-weight printer at low cost by mounting a printing and a magnetic head on the same carriage and switching the heads. CONSTITUTION:A thermal head 1 and a magnetic head 2 both for printing are mounted on a carrier 3 with a phase differential of 90 deg. between them. The carrier 3 is installed on a signal on a stand 5 for a carriage 4 through a rotator 6. Which is connected to a stepping motor 8 on the carriage 4 through a timing belt 7. The rotator 6 shifts the carrier 3 by rotation to change over the heads. The carriage 4 slides axially retained on sliding shafts 9, 10 to perform a printing operation or 'read/write' operation on magnetic stripes. A platen 11 is located in an opposed position to the head to be used and is caused by a spring 12 to press a slip form against either the head 1 or 2. In addition, the platen 11 is parked downward through a link 14, 15 when the form is fed and the head is switched by setting a solenoid 13 in a suction mode. |
