    摘要： An electronic sphygmomanometer includes CPU- controlled peripheral elements such as a pump (14), an amplifier (11), an A/D converter (10) and a printer (13). During measurement of blood pressure, power consumption is reduced by supplying power to these peripheral elements only when they are driven or operated. When a blood pressure measurement or a print-out of measured values ends, the CPU (3) acts to cut off its own power to reduce power consumption further. The sphygmomanometer further includes a timer (5) constantly supplied with power for the purpose of preserving time information. Operating power is supplied to the CPU (3) in synchronism with a pulse signal outputted by the timer every minute. When the pulse signal arrives, the CPU (3) reads in time information from the timer, causes the time information to be displayed by a display device (8a, 8b), then cuts off its own power and waits for the next pulse signal. By repeating such processing, time is displayed while power consumption is minimized.

    摘要翻译： 电子血压计包括诸如泵（14），放大器（11），A / D转换器（10）和打印机（13）的CPU控制的外围元件。 在测量血压期间，只有在驱动或操作这些外围元件时，才能通过向这些外围元件供电来降低功耗。 当血压测量或测量值打印结束时，CPU（3）会切断其自身的电源以进一步降低功耗。 血压计进一步包括定时器（5），其为了保存时间信息而持续供电。 工作电源每分钟与定时器输出的脉冲信号同步提供给CPU（3）。 当脉冲信号到达时，CPU（3）从定时器读入时间信息，使得时间信息由显示装置（8a，8b）显示，然后切断其自身的功率并等待下一个脉冲信号。 通过重复这样的处理，在功耗最小化的同时显示时间。
