電子機器及び画像形成装置
Document Type and Number:
Japanese Patent JP6551797
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To increase the number of detection targets by solving accuracy required by resistors and trade-off in the number of detectable targets (the number of resistors connectable in parallel).SOLUTION: An electronic apparatus comprises: N switches which are opened/closed in accordance with a state of the apparatus; a state detection circuit including N resistors each having one end connected in series to the N switches and having resistance values are different from each other, and connected in parallel, and a voltage dividing circuit connected in series to the other end of the N resistors and having a fixed resistance value; and a control part which controls the electronic apparatus. During a predetermined period in which at least one switch connected to the resistor other than a specific resistor having a maximum resistance value among the N resistors is brought into an open state, the control part detects an open/closed state of a switch connected to the specific resistor.SELECTED DRAWING: Figure 6
