PURPOSE:To attain the reading of an original and to display it in an erected display, even when the original is set upward or downward by providing a light transmissive original platen, an optical path changing means and an inverting means to invert a picture information having been photoelectrically converted, in parallel while sandwiching an photoelectric converting part. CONSTITUTION:When a picture is read from the bottom surface of a reader, a switching signal is H and in an inverting mode. An inverted plane image- formed on a sensor 13. In the inverting mode, a writing method in a line memory 8a is the same as a hot inverting mode, but an action at the time of reading is different. Namely, at the time of the inverting mode, in a read address generation circuit 86, the address of an even number line is outputted in a reversed order, like DOR FF, DOR FD..., when a horizontal address 83 is inputted in the order 0, 1, 2.... Besides, when the horizontal address 83 is inputted in the order 80, DOR 81, DOR 82..., the address of an odd number line is outputted in the reversed order like DOR 7F, DOR 7E, DOR 7D .... at the time of the inverting mode, a bit inversion circuit 8c bit-inverts and outputs an input data, and an erected picture information is stored in a picture memory 9.
