ELECTRONIC APPARATUS, PRINTING APPARATUS, AND CONTROL METHOD OF ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To prevent a malfunction of a device to be controlled with a simple configuration.SOLUTION: The electronic apparatus includes: an nMOS 113 for controlling lighting of an LED 50, which is a device; and a CPU 120 for supplying a control voltage for controlling the nMOS 113. An open drain port 123 and an input and output port 122 of the CPU 120 are connected to a gate terminal of the nMOS 113. Depending on an output state of the open drain port 123, supply of a control voltage to the gate terminal is controlled.SELECTED DRAWING: Figure 2
