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.
