    • An apparatus for indicating a strike at bowling alleys has a display board provided with a plurality of displays adapted to show a plurality of symbols thereon, a detector adapted to detect the occurrence of a strike, a microcomputer adapted to determine a several-digit number at random in accordance with an output from the detector, and a lighting circuit adapted to show numerals on the display board in accordance with numeric signals from the microcomputer. The microcomputer outputs random numeric signals successively to the lighting circuit with the microcomputer has received an output from the detector, to show numerals on the display board so that the numerals look as if they were rotated, and the outputting of the numeric signals to the lighting circuit is continued so as to show after the lapse of a predetermined period of time the determined numerals on the displays on the display board in order at predetermined time intervals.
    • 一种用于指示在保龄球道上的打击的装置,具有设置有适于显示多个符号的多个显示器的显示板,适用于检测撞击发生的检测器,微型计算机,适于确定数位数 随机地根据来自检测器的输出,以及照明电路,其适于根据来自微型计算机的数字信号在显示板上显示数字。 微型计算机将随机数字信号连续地输出到照明电路,微计算机已经接收到来自检测器的输出,在显示板上显示数字,使得数字看起来好像被旋转,并且将数字信号输出到照明 继续进行电路,以便以预定的时间间隔依次显示经过预定时间段在显示板上的显示器上的确定的数字。
