Ink jet recording apparatus utilizing solid semiconductor element

摘要

To supply electromotive force to a solid semiconductor element (11) in an ink tank (601) in a non-contact and stable manner. An electromagnetic apparatus (a standstill electromotive force supply unit) is placed at a home position HP. When a carriage (607) is at a standstill at this home position HP, if the electromagnetic apparatus is AC-driven, magnetic properties of both ends (magnetic poles) continue to change mutually and penetrate a solid semiconductor element (11) in the ink tank (601) on the carriage so that a constantly changing magnetic flux is generated. Electromotive force is generated by electromagnetic induction on a coil of the solid semiconductor element. In addition, if the carriage reciprocates during printing operation, the coil L of the solid semiconductor element crosses inside the magnetic flux due to a plurality of permanent magnets (a movement time electromotive force supply unit) arranged on a carrier path (range of movement), and so the electromotive force is generated on the coil by electromagnetic induction. Such electromotive force is converted into energy for activating and operating the solid semiconductor element.
