    摘要： A recording apparatus having an image reading operation capable of performing image reading by an image reading device for converting image information into electrical signals, and an image recording operation by a recording device for forming an image onto a recording medium is disclosed. The recording apparatus comprises a mounting unit capable of mounting both the image reading device and the recording device, a sensor for sensing which one of the image reading device and the recording device is mounted on the mounting unit, a quality preserving section for preserving the image quality in the recording operation, and a controller for controlling the reading operation by the image reading device, the recording operation by the recording device, and the quality preserving operations. The controller disenables the quality preserving operations by the quality preserving section, when the result sensed by the sensor indicates that the image reading device is mounted on the mounting unit.

    摘要： A recovery mechanism is provided with an elastic blade for wiping the formation surface of ink discharge ports of a recording head by allowing the leading end of its wiping surface to slide on the formation surface of ink discharge ports of the head, and an ink jet recording apparatus is provided with such recovery mechanism. For this recovery mechanism, a guide wall unit, which is extended to the vicinity of the formation surface of ink discharge ports, is arranged along the wiping surface of the blade in a state that the blade is in a wiping operation, and then, ink adhering to the leading end of the wiping surface of the blade is guided to a gap between the guide wall unit and the blade. In this way, the flying splash of ink at the time of wiping can be suppressed for the assurance of a stabilized wiping operation, thus making it possible for the recovery mechanism and the ink jet apparatus provided therewith to perform a high-quality recording.

    摘要： A device for controlling the power supplied to windings of a stepping motor includes a pulse generator for splitting one step drive period of the motor into a plurality of sections, the number of sections and increasing or decreasing depending upon the drive frequency. The pulse generator, also sets the duty cycle of a pulse applied to the motor. The device also includes a stepping motor drive circuit for exciting each phase of the motor with a current determined by the duty cycle of pulse, and a duty changing device for changing the duty cycle for each of plural sections in one excitation phase of the stepping motor, wherein a current wave input into the motor can be maintained as a sinusoidal wave from low-speed rotation to high-speed rotation of the motor by changing the number of sections in excitation depending upon serial drive operations, thereby achieving motor control with less rotation inconsistencies and less noise.

    摘要： A recording apparatus comprises a first gear, a second gear meshable with the first gear, a third gear meshable with the first gear and the second gear. The third gear has a peripheral surface on which a toothed portion meshable with the first gear and an untoothed portion not meshable with a toothed portion of the first gear are disposed opposable to the first gear, and a peripheral surface on which a toothed portion meshable with the second gear is disposed opposable to said second gear, a gear drive switching control unit controls switching such that when the toothed portion adjacent the untoothed portion of the third gear comes into contact with the first gear, the second gear and the third gear are meshed to rotate the third gear to oppose the untoothed portion of the third gear to the first gear, thereby releasing the contact between the first gear and the third gear.
