Abstract
Abstract The present invention provides a multi-purpose facsimile machine which functions as either a telecopier or a photocopier, at the selection of the user. The machine, when used as a telecopier, eliminates synchronization of transmitting and receiving units by storing transmitted data in a memory prior to printing. The facsimile machine includes a linear motor for driving both a print head and scan head on a single block. The linear motor includes at least one electrical coil driven along at least one lateral guide member formed from interspersed magnetic and non-magnetic materials. By selectively energizing the coil, the motor is advanced along its guide member by magnetic interactions. The electrostatic print head of the facsimile machine includes at least one thin conductive wire fused into at least one glass casing for providing a solid block structure for protecting and supporting the wire.
