PURPOSE:To improve assembling efficiency by using each pair of TV cameras, timing circuits, video memories, etc. CONSTITUTION:Each pair of TV cameras 5, timing circuits 21a, 21b video memories 22a, 22b, mixer circuits 23a, 23b and monitors 7a, 7b are mutually connected and are made controllable and operatably by a synchronizing signal generator 20 and an operation box 24. Then, the TV cameras 5 are driven by the horizontal and vertical synchronizing signals HV of the synchronizing signal generator 20 and when the patterns 1a, 1b on a glass plate to be measured are detected, the switch 241 of the operation box 24 is pushed and this signal enters the timing signal circuits 21a, 21b and is stored in the video memories 22a, 22b in synchronization with the vertical synchronizing signal V. Next, when the patterns 2a, 2b are detected, these are displayed on the monitors 7a, 7b by being mixed with the patterns 1a, 1b which have already recorded and are being continuously still displayed in the mixer circuits 23a, 23b. Hence, the assembling may be performed by aligning the patterns 1a, 2a, 1b, 2b while simultaneously observing the patterns 1a thru 2b. |
