Claims (2)
- 視準望遠鏡の角度を測定するエンコーダを備え、該エンコーダから送られてくる角度を読み込み、前回読み込んだ角度と今回読み込んだ角度との角度差の絶対値が所定値以下か否か判断し、前記角度差の絶対値が所定値以下なら一定時間読み込みを遅延して、前記一定時間の累積で、前記角度差の絶対値が所定値以下になったときから所定時間以上経過したか否かを判断し、所定時間経過後も前記角度差の絶対値が所定値以下のときオートフォーカスを開始するオートフォーカス手段を備えたオートフォーカス式測量機。
- 視準望遠鏡の水平角を測定するエンコーダを備え、該エンコーダから送られてくる水平角を読み込み、前回読み込んだ水平角と今回読み込んだ水平角との角度差の絶対値が所定値以下か否か判断し、前記角度差の絶対値が所定値以下なら一定時間読み込みを遅延して、前記一定時間の累積で、前記角度差の絶対値が所定値以下になったときから所定時間以上経過したか否かを判断し、所定時間経過後も前記角度差の絶対値が所定値以下のときオートフォーカスを開始するオートフォーカス手段を備えたオートフォーカス式電子レベル。
