PROBLEM TO BE SOLVED: To provide a controller capable of fully preventing a fraudulent action even when a prescribed setting operation can be performed with an external mechanical operation.SOLUTION: A slider 41 is formed so as to move between two positions: a light reception position for reflecting light from light emitting diodes 44A, 45A against a reflection mirror 43 of the slider 41 and forming a light reception route to allow phototransistors 44B, 45B to receive the reflection light; and a non-light-reception position for forming a deviation route to allow the reflection light to deviate from a light reception range of the phototransistors 44B, 45B. Thus, even when an opening is not formed in a main board case 22, a switch operation can be performed to eliminate the opening. Consequently, a gap for the insertion of an elongated wire tool is not formed, thereby to fully prevent a fraudulent action with the use of the elongated wire tool. |
