<p>PROBLEM TO BE SOLVED: To easily conduct power control. SOLUTION: In an optical sensor output setting circuit 1 with an optical sensor 8 receiving the light of a luminous element 4 with a light reception element 9 and detecting the existence of a detected body 12 put in between the luminous element 4 and the light reception element 9, the first resistor 5 and the second resistor 6 regulating the current flowing in the luminous element 4 are connected in parallel to the luminous element 4, and simultaneously the connection and separation of the second resistor 6 to the current path flowing in the luminous element 4 is made free by connecting a switch means 7 to the second resistor 6 and the value of a light reception resistor 10 regulating the current flowing in the light reception element 9 is set in the state the second resistor 6 is separated.</p> |
