Abstract
PURPOSE: To rotate a display screen at an arbitrary time by an external switch, etc., by using a selection circuit and a count up/down switching circuit to read out a character code from a start point to an end point under a normal state and read it from the end point to the start point under a state where the display screen is rotated at 180°.
CONSTITUTION: A character code displayed on an image receiver enters display memory 1, and a character code can be read out arbitrarily from display memory 1 by the address designated by memory address circuit 2. Then, by an external switch, etc., selection circuit 3 and count up/down switching circuit 4 are used to be able to select a start address and count-up under a normal state or select an end address and count-down under a state where the display screen of the image receiver is rotated at 180°. Then, under the normal state, the character code is read out from the start address toward the end address in order; and under the state where the display screen is rotated at 180°, the character code is read out in the reverse order. As a result, the display screen can be rotated at an arbitrary time by the switch, etc.
