PROBLEM TO BE SOLVED: To improve discrimination accuracy of combination with light source while suppressing the size from increasing.SOLUTION: A control unit detects a voltage of a third terminal, and compares the detected the voltage of the third terminal to a first threshold value and a second threshold value which is lower than the first threshold value. When the voltage of the third terminal is equal to or larger than the first threshold value, the control unit discriminates the type of the light source as a first type. When the voltage of the third terminal is equal to or smaller than the second threshold value, the control unit discriminates the type of the light source as a second type. When the voltage of the third terminal is higher than the second threshold value and smaller than the first threshold value, the control unit determines the type of the light source as indefinite.SELECTED DRAWING: Figure 2
【課題】大型化を抑制しつつ光源との組み合わせの判別精度の向上を図る。【解決手段】制御部は、第3端子の電圧を検出し、検出した第3端子の電圧を第1しきい値、及び第1しきい値よりも低い第2しきい値と比較する。制御部は、第3端子の電圧が第1しきい値以上の場合は光源の種別を第1の種別と判別する。制御部は、第3端子の電圧が第2しきい値以下の場合は光源の種別を第2の種別と判別する。制御部は、第3端子の電圧が第2しきい値よりも高くかつ第1しきい値未満の場合は光源の種別を不定とする。【選択図】 図2
