To assure that the space efficiency of a recording apparatus can be improved, the length of each of cables to be electrically connected to a mechanism section can be optimized, and the recording apparatus having excellent handling properties can be produced with small dimensions at a reduced cost, a controlling section for controlling a mechanism section substantially composed of an automatic feeding section, a conveying section, a discharging section and a recording section, each of which is associated with a recording operation to be performed by the recording apparatus, is arranged above the mechanism section.

Recording apparatus

An ink-jet recording apparatus includes a positioning device for postioning a recording head on a carriage and an electrical connecting device for establishing electrical connection between the recording head and a main body portion. The positioning device and the electrical connecting device are provided on the carriage independently of each other. Therefore, the recording head and an ink tank can be certainly and simply installed on the recording apparatus. Also, an information processing system employs such recording apparatus to output input information, such as characters, image or so forth on a recording medium.

Recording apparatus with improved head installation mechanism

An image recording apparatus for performing image recording on a recording medium by using an ink sheet having a plurality of colors of ink includes a recording head acting on the ink sheet to perform image recording on the recording medium, a first feeding unit for feeding the ink sheet through a clutch, a second feeding unit for feeding the ink sheet without going through the clutch, and a unit for selectively switching between the first feeding unit and the second feeding unit.

An ink jet recorder is provided with a recovery device for preventing unsatisfactory ink discharge of a recording head, the recovery device being provided with ink suction means having a cap covering an ink discharge port, a vent valve for opening and closing the interior of the cap with respect to the atmosphere and a suction pump for producing a negative pressure in the cap, and wiping means having a cleaning blade adapted to be advanced and retracted relative to the ink discharge port. The cleaning blade is protruded when a motor effecting the sequence operation of the ink suction means revolves in one direction, and is stopped at its retracted position when the motor revolves in the opposite drection. A method of operating such ink jet recorder is characterized by operating the recovery device in one cycle sequence comprising the steps of bringing the cap into intimate contact with the ink discharge port, closing the vent valve, operating the suction pump, opening the vent valve, restoring the suction pump to its initial state, operating the suction pump, restoring the suction pump to its initial state, closing the vent valve, spacing the cap apart from the surface of the ink discharge port, opening the vent valve, and restoring the suction pump to its initial state.
