    摘要： A recording apparatus includes a feed roller which feeds a paper sheet, a feed motor which drives the feed roller, and a loss-of-synchronism detecting unit which detects loss of synchronism of the feed motor. When loss of synchronism of the feed motor is detected by the loss-of-synchronism detecting unit, the rotational speed of the feed motor is reduced stepwise. Accordingly, it is not necessary to provide a high operational margin in the motor, and a recording apparatus, in which the motor and power supply costs are reduced, can be provided.

    摘要： A flow control valve having a seating surface formed on a valve element to contact a valve seat when the valve is closed has a shape of a part of a hypothetical spherical surface having a spherical center at a center of a supporting member. Therefore, the distance from the center of the supporting member to the seating surface is kept constant, and the valve element can be seated at a periphery of the valve seat without a gap, even if the shaft is inclined. Thus, the valve leakage is reduced. The supporting member supports a shaft connected to the valve element movable in an axial direction of the shaft. The center of the supporting member is aligned with a center of the valve seat. Movement of the supporting member in a radial direction of the supporting member is prohibited. Therefore, the center of the supporting member is not displaced from the center of the valve seat in the radial direction. Accordingly, the displacement of the shaft in the radial direction can be prevented. Therefore, the valve element is certainly seated on the valve seat, and the valve leakage is prevented.

    摘要： A printing apparatus which can detect remaining ink with high precision regardless of trembles of ink surface in an ink tank caused by various factors such as scanning speed of a carriage, scanning width, impact of the carriage at the time of reversing the carriage scanning direction and the like, and can perform printing by efficiently utilizing the remaining ink, and a facsimile apparatus using the above printing apparatus. According to the apparatus, when a CPU controls print operation, the CPU dynamically changes the threshold value as a determination reference, utilized to detect remaining ink on the basis of an output current of a reflection type photosensor, in accordance with the scanning speed of carriage movement, the scanning width, and the stop period for reversing the scanning direction.
