    • An apparatus for controlling an operating stroke of a reciprocating member to be reciprocated by a drive motor. The apparatus includes an encoder adapted to generate pulses each of which corresponds to a predetermined incremental distance of movement of the reciprocating member, a counter for counting the pulses during movement of the reciprocating member in a forward direction, a device for converting the operating stroke into the number of the pulses corresponding to a multiple of the incremental distance of movement, and a residual distance which is a difference between the operating stroke and the multiple, a device for converting the residual distance into a corresponding residual time, and a device for commanding the drive motor to stop an operation thereof causing a further forward movement of the reciprocating member, when the residual time has elapsed after a count of the counter is equal to the above-indicated number of the pulses.
    • 一种用于控制由驱动马达往复运动的往复运动件的运行行程的装置。 该装置包括编码器,其适于产生脉冲,每个脉冲对应于往复运动部件的预定的增加运动距离,用于在往复运动部件沿向前方向运动期间计数脉冲的计数器,用于将运转行程转换成 对应于增量移动距离的倍数的脉冲数,以及作为操作行程与倍数之间的差的剩余距离,将剩余距离转换为相应的剩余时间的装置,以及用于命令的装置 当计数器的计数等于上述数量的脉冲之后剩余时间已经过去时,驱动马达停止其运动,从而进一步向前运动往复运动件。
