Title:
INPUT DEVICE, AND METHOD OF CONTROLLING THE SAME
Document Type and Number:
Japanese Patent JP2019205072
Kind Code:
A
Abstract:
To simplify a circuit configuration in an input device comprising a plurality of switches and to prevent breakage of a controller.SOLUTION: A device for inputting an operation instruction includes: at least two switches each of which has one end and the other end; and a controller 10 that has at least one input unit and at least two input/output units. The input unit is connected with the respective one ends of the two switches. A first input/output unit of the input/output units is connected with the other end of a first switch of the two switches. A second input/output unit of the input/output units is connected with the other end of a second switch of the two switches. The controller, when outputting a scan signal from the first input/output unit, switches the second input/output unit to an input acceptance state to detect a magnitude of a voltage generated at the input unit, and thereby, obtains a conduction state of the first switch.SELECTED DRAWING: Figure 1
