Character codes of characters constituting each sentences are stored in a series of addresses of the line ROM and, when a given sentence is to be displayed, a head address of a series of addresses is written in the display RAM by the CPU. A decoder (30) sequentially and automatically reads the character codes from address beginning at the head address at every predetermined timings by referring position data of display positions on a screen of a monitor television (54) from a count circuit (48).
