摘要: A display input device has a touch screen, which includes a touch panel for accepting a touch operation, and a control portion. The control portion detects contact position on the touch panel with a contact body, contact size on the touch panel with the contact body, and contact pressure on the touch panel with the contact body, judges whether calibration is necessary based on the contact position, contact size, and contact pressure, and performs calibration when it is judged that calibration is necessary.

摘要: An input device includes a touch panel, a touch button, a first measurement device, a second measurement device, a first detection device that detects a touch position on the touch panel, based on a difference between the electrostatic capacitance measured by the first measurement device and a panel baseline value, a second detection device that detects a touch operation on the touch button, based on a difference between the electrostatic capacitance measured by the second measurement device and a button baseline value, an error decision device that decides that the touch operation is an error, when the touch operation satisfies a predetermined condition, and a controller that sets the button baseline value to an initial value, when the error decision device has identified an error, and sets the panel baseline value to an initial value, when the error decision device has not identified an error.

摘要: An image forming apparatus has an operation portion, an operation sensing portion, a human detecting portion, and a sensing period adjusting portion. The operation portion accepts operation by a user. The operation sensing portion senses operation on the operation portion. The human detecting portion detects the presence of a human body within a previously set detection distance. The sensing period adjusting portion adjusts a operation sensing period of the operation sensing portion based on the detection distance of the human detecting portion.
