    摘要： A linear motor including a plurality of movers (1a to 1c), each of which is formed with an armature having a polyphase balancing winding (Ru to Rw), and a stator having a permanent magnet or a secondary conductor is configured such that the plurality of movers (1a to 1c) are disposed on the single stator; and the polyphase balancing windings (Ru to Rw) in the respective movers (1a to 1c) are connected in series. Accordingly, there can be obtained an inexpensive linear motor which is capable of driving a large machine, which is capable of canceling cogging force, which offers facilitated assembly of movers, and which can provide thermal protection of the movers with ease.

    摘要： An image forming apparatus includes a paper feed station from which sheets can be fed from a plurality of roll sheets only by placing the roll sheets in the station, a recording station for recording desired images on the sheets, and a processing station for delivering the sheets on which the images are recorded. The recording station includes a platen roller and a driving pinch roller for pushing and conveying a fed sheet while the sheet is drawn by suction by a suction chamber, a carriage unit for recording an image on the sheet on the suction chamber while moving along the sheet, and a pair of paper delivery rollers for delivering the sheet on which the image is recorded. The processing station includes a table on which the delivered sheets can be sequentially stacked in a predetermined position, and a biasing spring for biasing the pivotal distal end portion of the table.
