CONSTITUTION:A pattern of a liquid crystal display element 2 of a desk calculator 1 is divided through a mittor 4 into left and right parts by V mirrors 5 and 6 and is reflected upward by mirrors 7 and 8. Next, divided patterns are incident to X mirrors 11 and 12 by mirrors 9 and 10. The image of a right part A moved to a position A' is incident to a mirror 13 and is reflected by a mirror 14 and is incident to an ITV camera. Thus, when the display element is long sideways and the limit length of the resolution of the ITV camera in the horizontal direction is (a) and that in the vertical direction is (b), the display part is divided by a broken line C, and the right part A is moved to the position A', and thus the whole of the display part is read by one ITV camera. |
