摘要:
PURPOSE:To obtain hand display stopwatch enabled in split display and capable of starting measurement during the return of hand, by outputting a motor drive signal in a cycle faster than a reference signal by a gate circuit when it is judged by a coincidence circuit that the contents of a latch circuit and the hand position counter are not coincided. CONSTITUTION:When the coincidence of a latch circuit 9 and a hand position counter 11 is released and a coincidence signal Ye outputted from a coincidence circuit 10 comes to ''L'', a quick sending signal phis is certainly outputted from a gate circuit 12 and hand 16 is quickly sent at 16Hz. Therefore, when the position of the hand is not coincided with a measuring time, a step motor is driven in a cycle faster than a reference signal until the position of the hand comes up with the measuring time. By the constitution as mentioned above, even in hand display stopwatch for displaying hand by a step motor, split display and start during the return of the hand are enabled.

目的:为了获得在分割显示中启用的手表显示秒表,并且能够在返回时开始测量,当通过重合电路判断出通过门电路比基准信号更快的循环输出电机驱动信号时, 锁存电路和手位计数器的内容不一致。 构成:当闩锁电路9和指针位置计数器11的重合被解除并且从符合电路10输出的符合信号Ye变为“L”时,从门电路12肯定地输出快速发送信号phis 手16快速发送在16Hz。 因此,当手的位置与测量时间不一致时,步进电机以比参考信号更快的周期被驱动,直到手的位置出现测量时间。 通过如上所述的结构,即使在步进电机中显示手的手动显示秒表,也可以在手的返回期间进行分割显示和启动。
