Abstract: A non-volatile memory (1) which comprises an insulating substrate (11) having a plurality of first electrodes (15) extending therethrough from a front surface of the substrate to a rear surface thereof, a second electrode (12) formed on one surface side of the substrate (11), and a recording layer (14) held between the first electrodes (15) and the second electrode (12) and variable in resistance value by electric pulses applied across the first electrodes (15) and the second electrode (12), the plurality of first electrodes (15) being electrically connected to the recording layer (14) in a region constituting a single memory cell (MC). The non-volatile memory (1) can be reduced in power consumption and has great freedom of design and high reliability.

Abstract: A sheet feeding device is provided with a guide member for guiding sheets of paper sent out from the paper pile section in the sheet feeding direction, a feeding roller which is installed above the guide member and by which a sheet of paper is transferred in the sheet feeding direction, and a separation member which is engaged in non-contact with the feeding roller in the axial direction thereof and by which sheets of paper can be separated sheet by sheet between the separation member and the feeding roller and is so composed that a separation portion formed between the feeding roller and the separation member can be arranged in the downstream side in the sheet feeding direction from a minimum clearance portion formed between the guide member and the feeding roller.
