Claims (1)
する指示手段と、 該指示手段により計測開始を指示されたときは
直ちに前記時間計測を開始し、該指示手段による
計測開始の指示がないときは前記減算手段による
予め定められた時間の減算が完了した時点で前記
時間計測手段の時間計測を開始する開始制御手段
を有することを特徴とする時間計測装置。[Scope of Claim for Utility Model Registration] Subtraction means for subtracting a predetermined time; time measurement means for measuring time; instruction means for instructing the time measurement means to start measuring time; and measurement by the instruction means. When instructed to start, the time measurement is started immediately, and when there is no instruction to start measurement by the instruction means, the time measurement by the time measurement means is started when the subtraction means completes subtraction of a predetermined time. A time measuring device characterized by having a start control means for starting.
