Claims

[Scope of Claim for Utility Model Registration] (1) A parameter setting device capable of changing the value of a parameter, which has an up operation means for instructing to increase the value of a parameter and a down operation means for instructing to decrease the value of the parameter. 1. A parameter setting device comprising: a sounding means that produces a confirmation sound in different manners in a state within a parameter variable range and in a state outside the parameter variable range where the parameter value cannot be changed. (2) The sounding means generates the confirmation sound each time the value of the parameter changes and is set by the up operation means or the down operation means, in a state within the variable range of the parameter;
2. The parameter setting device according to claim 1, wherein a confirmation sound is not produced in a state outside the parameter variable range. (3) The sounding means generates the confirmation sound each time the value of the parameter changes and is set by the up operation means or the down operation means, while the parameter is within the variable range;
2. The parameter setting device according to claim 1, wherein the parameter setting device continues to emit a continuous confirmation sound in a state outside the parameter variable range. (4) The sounding means does not emit the confirmation sound even if the value of the parameter is changed and set by the up operation means or the down operation means in a state within the variable range of the parameter;
The above-mentioned confirmation sound is emitted when the above-mentioned parameter is outside the variable range, and from that point on, the above-mentioned confirmation sound is emitted every time the above-mentioned up operation means or the above-mentioned down operation means is operated in a state outside the above-mentioned parameter variable range. 2. The parameter setting device according to claim 1, wherein the parameter setting device generates a sound.
