Claims
- 1. An operation inputting apparatus for generating a cursor control signal used to control the position of a cursor on a display screen, the apparatus comprising;
- an operation member in which an operating member is deformed by a force applied to the operating member and a variation in resistance valued corresponding to a degree of deformation is detected;
- a pressure detection sensor connected to the operation member for detecting a load force applied to said operation member, and for generating a detector signal having a voltage level which is related to the detected load force;
- an analog digital converter for converting the detector signal into a digital data value;
- reference value setting means for generating an offset reference value, an allowable offset range centered at the offset reference value, and an output reference value;
- output judgment means for determining if the digital data value is within the allowable offset reference range; and
- reference value setting changing means for changing the offset reference value and the output reference value in response to an amount of variation of the digital data value only when said output judgment means determines, after a predetermined time period, that the difference between the digital data value and the offset reference value remains within the allowable offset range.
- 2. An operation inputting apparatus according to claim 1, wherein the offset reference value is changed in response to a variation of the digital data value every predetermined time period when the digital data value is within an offset allowable value, and the output reference value is changed in response to a variation of the digital data value every second predetermined time period.
