Operation inputting apparatus |
摘要 |
An operation inputting apparatus is disclosed by which, even if a load detection output remains after an operation of a stick type operation member is stopped by an operator, a load detection output which coincides with stopping of the operation of the stick type operation member can be obtained. A pressure detection sensor detects a load force applied to the stick type operation member upon operation of the stick type operation member, and a comparison circuit compares a load detection value obtained from the pressure detection sensor with a preset load value. A timer circuit adjusts a count value in response to a result of the comparison and detects the count value equal to zero to produce a zero detection output. A judgment level production section sets two judgment levels for presence or absence of an output in response to the zero detection output. The judgment levels are set such that the judgment level for presence or absence of an output when the zero detection output is supplied is higher than the judgment level for presence or absence of an output when the zero detection output is not supplied. |
