MAGNETIC COLOR PRINTER/COPIER

摘要

In a magnetic printer, magnetic needles (5) are arranged in a row on the outer periphery of a holding plate (4, 15) to form a magnetic head producing a magnetic pattern corresponding to magnetic information. Further, in the printer, an ultrafine pigment magnetic powder-jetting pipe (3), a heating pipe (22), a cooling pipe (23), and a temperature measurer (24) are arranged close to one another at positions opposed to the magnetic head. An object on which printing is to be performed is passed between the magnetic head and each of the pipes and temperature measurer, so that the ultrafine pigment magnetic powder is fixed on the object at positions corresponding to the magnetic information. The ultrafine pigment magnetic powder-jetting pipe (3) is connected to a pigment-preparing device (8) for preparing the ultrafine pigment magnetic powder. The pigment-preparing device (8) is constituted of tanks (7) for separately storing a thermoplastic agent, a magnetic body, and pigment, and of a pigment-compounding chamber (14) for compounding the different powder materials in the tanks (7).
