then the upper top plate 3 is turned clockwise 90 degrees so that the pivot piece 322 is turned to a vertical orientation then the top plate 3 is rotated counterclockwise 90 degrees about an upper pivot 322 finally the extension arm 32 and the upper slide plate 33 are pushed in so that the end of the upper slide plate 33 fits into a securement cavity 171 at this point the top surface of the upper slide plate 33 and the upper surface of the main plate 1 are at the same level so as to be flush with each other after the top plate 3 has been extended upper slide plates 33 therein can also be extended so as to form the different views shown in fig9 c 9 d and 9 e fig1 11 and 12 show several other features which can be applied to this invention for example in fig1 it can be seen that if it is desired to use the present invention as a writing surface that a cover plate 5 can be used to insure even smoother writing than would be otherwise possible due to the edges of the main side and top plates 1 2 and 3 respectively another nice feature of the present invention is that it can be snapped close by means of catch 42 which engages.
