OPERATION DEVICE, BEVERAGE SUPPLY DEVICE, AND OPERATION METHOD
Document Type and Number:
Japanese Patent JP2023167544
Kind Code:
A
Abstract:
To provide an operation device which can be hygienically operated and can suppress erroneous determination on whether or not an operation is performed.SOLUTION: An operation device comprises: a non-contact type operation unit which includes an optical sensor that emits detection light in a prescribed wavelength and outputs a detection signal in the magnitude according to the light reception state of light in the prescribed wavelength; an operation determination unit which determines that an operation is performed to the non-contact type operation unit when the magnitude of the detection signal is equal to or greater than a determination threshold; and an erroneous determination suppression unit which suppresses erroneous determination in the operation determination unit. The erroneous determination suppression unit increases the determination threshold in a case where a difference between the magnitude of the detection signal in the standby time of the operation and the determination threshold is less than a change reference value.SELECTED DRAWING: Figure 13
