Abstract
In a wire-dot print head which comprises print elements arranged in a ring, each having an electromagnet formed of a core and a coil, and in which the electromagnets are divided into a plurality of blocks so that each block has a plurality of electromagnets, and a common current conduction control element is provided for each block and used to control current through the coils of the electromagnets in the block, the electromagnets of each of at least some of the blocks are disposed so as not to be physically adjacent to each other. Because of the above arrangement, currents through the coils due to magnetic interference between the adjacent electromagnets is reduced and power consumption is reduced.
