Abstract: PURPOSE:To shorten the image forming time by processing in parallel an image formation and a pressure transfer. CONSTITUTION:A first image and a second image are formed in an image forming area l1 and l2, respectively. To the tips of each area, a non-image area (b) is determined. As for carrying rollers 22b, 22c, when carrying of a media sheet being in a roughly integer multiple position of an area l, based on the area (b) as a reference stops, the area (b) becomes a position of the rollers 22b, 22c. In an area (a) of the media sheet between the roller 22c and a pressure roller 25, no image is formed. A buffer roller 24 is movable in the directions as indicated with arrows A, B, positioned in a home position (HP) in a regular state, and moves to 24-1, 24-2 and 24-3 by a motor.

Abstract: PURPOSE:To simplify constitution of a sense amplifier and reduce current consumption by constituting a pair of gates from a flip-flop to a bit line of MOSFET of opposite conductivity and driving by a pair of word lines having signals contrary to each other. CONSTITUTION:When writing, gates 16, 17 are opened by word lines 14, 15 and prescribed voltage is applied to both or one of bit lines 12, 13.
