Abstract: A magnetic ink reader includes a conveyance mechanism for a sheet, a magnetizing mechanism configured to magnetize magnetic ink on the sheet and including a magnet having a first side of a first polarity, that is arranged to face the sheet, and a yoke that is formed of a soft magnetic material and includes a base portion attached directly to a second side of the magnet, and a partition wall of a second polarity extending towards the conveyance path, such that a side surface of the partition wall faces a third side of the magnet and an end surface of the partition wall faces the sheet, and a magnetic detection head for detecting magnetism of magnetized magnetic ink. A first distance between the conveyance path and the first side of the magnet and a second distance between the conveyance path and the end surface of the partition wall are different.

Abstract: A support structure for a detachable platen roller of a printer that rotates to feed paper, or the like includes a frame that holds the platen roller and a pair of bushings attached to the frame. Ends of a shaft of the platen roller are inserted into the bushings. A part of either the frame or each of the bushings located around the shaft and closer to a guide surface of the platen roller than the frame in a longitudinal direction of the platen roller forms a support part that receives a force applied by a print head pressing against the platen roller.
