Abstract
【解決手段】システムコントローラ70は、レーザー照射解除スイッチ22がオンしている場合(S201,Y)には、励起用レーザー光源33が点灯しているか否かを判断し(S202)、点灯していない場合には、点灯準備のためレーザー状態表示部23bを点滅させ、励起用レーザー光源の試射を行う(S204)。試射の際には励起光用シャッター34が閉じており、励起光が外部に照射されない。試射を繰り返し安定して点灯できる状態となると、励起用レーザー光源を消灯し(S206)、レーザー状態表示部を点灯させ(S207)、励起光用シャッター34を開く(S208)。この状態で励起光点灯信号が入力すると、励起用レーザー光源が点灯してライトガイド16に励起光が入射する。
【選択図】図7
Description
レーザー点灯ボタン23aが操作された際に励起用レーザー光源33が点灯中であれば(S303,Y)、システムコントローラ70は励起用レーザー光源33を消灯させ(S306)、図6の周期タイマー割り込み処理に処理を戻す。
