    • An automatic deck adjusting apparatus having a tape running system adjusting mechanism for adjusting a VCR deck automatically and control means for controlling the adjusting mechanism to adjust the tape running system automatically. The tape running system adjusting mechanism comprises a plurality of screw driver tip assemblies for screwing adjustment screws and/or nuts in the system, a motor assembly for rotating the screw driver tip assemblies by a predetermined angle, a driver housing for fixedly supporting the screw driver tip assembly and the motor assembly in place, moving means attached to the driver housing for reciprocating the housing, a positioning means aligning the deck mechanism and the screw driver housing to be coincided in position with each other when they are coupled together and, a video camera for monitoring the position of the tape passing through guide posts and an audio/control head assembly or head drum. The control means comprises a main computer for controlling entire apparatus, a motor controller for controlling the motor assembly to rotate multiple driver tip assemblies by a predetermined angle under a control of the main computer, a position detector for receiving video signals from the video camera monitoring the position of the tape passing through the guide posts and the audio/control head assembly or the head drum, calculating the position of the tape on the posts and head assembly and informing the position of the tape to the main computer, a video signal processor for amplifying and detecting the video signal produced from a video head in the deck, obtaining an envelope waveform from the detected video signal and converting the envelope waveform to digital signal to be transferred to the main computer and, an audio signal processor for calculating an effective value of signal produced by an audio head in the deck, wherein the main computer controls the tape running system adjusting mechanism, the motor controller, the positioning detector the video signal processor, the audio signal processor and the control signal processor to adjust automatically the tape running system of the deck.

    • A non-contacting type method for measuring perpendicularity of a straight post installed perpendicularly to a reference plane is performed by picking up partial images of an upper end and a lower end of the post in two directions vertical to each other to combine obtained images into one image, calculating inclinations or deviations of four images of lower end portion and upper end portion in the combined image, and comparing the inclinations or deviations to measure the perpendicularity with respect to the reference plane. An apparatus thereof includes a measuring section for optically obtaining image data of the object to be measured, a measuring-part driving unit for driving the measuring part in the X, Y and Z directions which are perpendicular to one another, and a data processing part for processing and calculate the image data obtained by the measuring part to display the result of perpendicularity calculation. Thus, by adopting an optical principle without actually contacting the measured object, a problem of causing an error due to the direct contact is solved while being applied to the measurement of an object with a small measuring space. Because a measuring section is freely moved with respect to the X, Y and Z directions to execute the measurement, even a different object requires no separate setting to thus facilitate the measuring.
    • 用于测量垂直于基准平面安装的直柱的垂直度的非接触式方法是通过在垂直于彼此的两个方向上拾取柱的上端和下端的部分图像来进行的,以将获得的图像组合成一个 图像,计算组合图像中的下端部分和上端部分的四个图像的倾斜度或偏差,以及比较倾斜度或偏差以测量相对于参考平面的垂直度。 其装置包括用于光学地获得被测量物体的图像数据的测量部分,用于驱动彼此垂直的X,Y和Z方向上的测量部分的测量部分驱动单元和数据处理部分 用于处理和计算由测量部分获得的图像数据以显示垂直度计算的结果。 因此,通过采用没有实际接触测量对象的光学原理,在应用于具有小测量空间的物体的测量的同时,解决了由于直接接触引起的误差的问题。 由于测量部分相对于X,Y和Z方向自由移动以执行测量,所以即使不同的对象也不需要单独设置,从而便于测量。
