Title:
INFORMATION READING APPARATUS
Document Type and Number:
Japanese Patent JP2018173933
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a configuration using an electrostatic capacitance touch sensor which suppresses influence by a noise and can detect a slow touch with satisfactory accuracy.SOLUTION: An electrostatic capacity type touch sensor 51 is disposed on a touch detection position 15 which is touched upon start of reading. In a memory 35, a count value acquired by using a switch portion 50 is regularly stored as a comparison value. In a touch detection processing executed by a control unit 40, a count value of the touch sensor 51 is acquired so that a count value of a touch state is set smaller than that of a non-touch state. If it is determined that a state changed to a predetermined change state in which a count change amount ΔNx obtained by subtracting any one of a plurality of comparison values stored in the memory 35 from the current count value is set smaller than ON threshold value ΔNth1, the touch state is detected.SELECTED DRAWING: Figure 6
