On page 17, line 10 of the specification, "comparison section" is corrected to "comparison circuit." On page 17, line 11 of the specification, "display section" is corrected to "display circuit."

Claims

[Claims for Utility Model Registration] (1) A plurality of resistors connected in series and having a power supply voltage applied to both ends; A plurality of reed switches whose ends are connected to each other to serve as detection terminals, and one or more reed switches which are movable along the arrangement direction of the reed switches and which correspond to changes in the liquid level to be detected. 1. A float-type liquid level detector comprising: a detection part equipped with a float having a magnet that can operate the float; and a display part that displays a detection value obtained from a detection terminal of the detection part. (2) The float type liquid level detector according to claim 1, wherein the display section is a voltmeter. (3) the display section is provided corresponding to the plurality of reed switches, and a reference voltage value obtained by dividing the power supply voltage into predetermined levels is input to the input terminal;
a comparison circuit having a plurality of comparators to which the output of the detection terminal is applied in parallel to the other input terminal and outputs a signal when the detection terminal output exceeds the reference value; and an output of the comparison circuit. Utility model registration claim 1, characterized in that the display circuit comprises a display circuit provided on the side corresponding to each of the comparators and having a plurality of segments for displaying the liquid level in response to the input of the signal. Float type liquid level detector as described.
