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.

摘要： An image processor includes a first image information processing unit which processes image information with respect to a sheet medium. A first sheet medium feeding path guides the sheet medium to the first image information processing unit, and exhausts the sheet medium from the first image information processing unit. A second image information processing unit processes image information with respect to a sheet medium while allowing a head for processing image information to travel serially. The second information processing unit is arranged on a side lower than the first image information processing unit. A second sheet medium feeding path guides the sheet medium to the second image information processing unit, and exhausts the sheet medium from the second image information processing unit. An electric circuit board is arranged below the feeding path of the first sheet medium, and above the feeding path of the second sheet medium. The electric circuit board is arrange on the reverse side of the head for processing image information. In this way, the number of boards and harnesses are reduced, thus reducing cost, and enhancing assembling capability and reliability.

摘要： A printer that performs high-precision residual-ink detection regardless of various movements accompanying print operation and facsimile apparatus using the printer. When an ink cartridge reciprocates along a main-scanning direction, ink surface of ink 91 varies depending on a moving direction and moving condition (stationary state, uniform motion, accelerated motion and decelerated motion) of the ink cartridge. Accordingly, the residual-ink detection is controlled such that a residual-ink amount can be detected by using photosensor 11 and reflection board 93, at the same detection timing (e.g., always at timing of uniform motion).

摘要： An area on the printing sheet which can be printed through a single scanning operation of a printing head is divided into a plurality of smaller areas. The printing sheet is transported a distance corresponding to each divided area to print the image using different nozzles of the printing head for each divided area. When a back end portion of the printing sheet is printed, the distance transported is reduced to set inoperative nozzles that are not used for the printing operation. Then, when the printing sheet slips out from the upstream roller pair and it is then detected that the printing sheet is to be transported a distance longer than predetermined amount of rotation of the roller, the inoperative nozzles are used to shift an operative nozzle range depending on the extra amount of rotation. Thus, the extra transportation of the printing sheet is corrected.

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.
