Japanese Patent JPS6075068
Kind Code:
U
Abstract:
A printer comprising a printing mechanism, a control circuit which controls said printing mechanism and a power supply including battery, wherein said power supply provides the first stabilized power source circuit which converts an output voltage of said battery to the predetermined first supply voltage and then supplies it to said printing mechanism and the second stabilized power source circuit which converts an output voltage of said battery to the second supply voltage which is lower than said first supply voltage and then supplies it to said control circuit, and moreover a detecting circuit, which is composed of a transistor and resistors and detects that difference between the supply voltages of said first stabilized power source circuit and second stabilized power source circuit has reached a value lower than the predetermined threshold value, is also provided, and moreover the printing operation is controlled on the basis of an output signal of the detecting circuit.
