    • An encoder signal compensation method and the apparatus thereof are described. The encoder signal compensation method includes the following steps. First, encoder output signals are read to calculate compensation parameters. Subsequent encoder output signals are compensated according to the calculated compensation parameters and the compensated encoder output signals are utilized to control a printing process. The encoder signal compensation method is effective in eliminating width errors and phase errors of the encoder output signals. Another embodiment of the invention is to provide a printing apparatus utilizing the encoder signal compensation method to reduce high frequency banding, effectively improving the printing quality.
    • 对编码器信号补偿方法及其装置进行说明。 编码器信号补偿方法包括以下步骤。 首先,读取编码器输出信号以计算补偿参数。 随后的编码器输出信号根据计算的补偿参数进行补偿,并且补偿的编码器输出信号用于控制打印处理。 编码器信号补偿方法有效消除编码器输出信号的宽度误差和相位误差。 本发明的另一个实施例是提供利用编码器信号补偿方法来减少高频带的打印装置,有效地提高打印质量。

    • A nail-driving device includes a housing, a trigger unit operable to fire a nail from the housing, and a resilient member disposed between first and second safety members. When a workpiece-engaging end of the first safety member is pressed against a workpiece such that a tip of the nail is moved into a nail hole in the workpiece, the first safety member pushes and moves the resilient member and the second safety member toward the trigger unit along a longitudinal direction until a stop-engaging portion and a trigger-engaging portion of the second safety member come into contact with a stop portion of the housing and the trigger unit, respectively, thereby preventing further movement of the second safety member along the longitudinal direction while allowing for movement of the first safety member toward the second safety member against the biasing action of the resilient member.
