Abstract

PURPOSE: To reduce noises caused by a fan motor and eliminate the waste in consumption of elecricity by driving the fan motor only at the time of print-out in a driving method for a cooling fan of the electronic apparatus with a printer.
CONSTITUTION: When an instruction for print-out is delivered by an operational controlling part 2, signals are given to a motor 3 for driving a printer carriage, a motor 4 for feeding the printer with paper and a printer hammer mechanism 5. These signals are inputted in an OR gate 7 and the output signal from this OR gate makes a trigger-one shot circuit 7 operate. The output signal of the circuit 7 and the output signal of the OR gate 6 are inputted in an OR gate 8 and thereby a switching transistor 9 for the fan motor 10 is turned on. Since the circuit 7 is used, the fan rotates continuously even when the printer operates intermittently, and it rotates for a certain time after the printing operation is ended.
