Masami Ohkawa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A printer for printing on a print medium. A type carrier is in the form of an endless belt having a plurality of type elements on a side face. A hammer mechanism urges the type elements in the print medium into contact. The hammer mechanism extends substantially parallel to a portion of the type carrier and includes a hammer member for each printable position of the printer. A print drum mechanism selectively drives the hammer mechanism. The print drum mechanism includes the print drum with a plurality of projections around the peripheral surface of the print drum. There are a like number of projections and hammer members. Each of the projections is adapted to drive a separate hammer member and rotation of the print drum results in the driving of the hammer members by the projections. A control mechanism coupled to the type carrier and the print drum mechanism selectively advances the endless belt relative to the hammer mechanism and rotates the print drum.
