  • Patent number: 6086178
    Abstract: 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).

  • Patent number: 6012794
    Abstract: 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.

  • Patent number: 5903365
    Abstract: A sheet conveying apparatus and an original reading apparatus according to the present invention can reduce a load of a drive system for rotating a convey rotary member and can be made compact. The apparatus includes an original convey roller rotatably supported by a frame, and a contact sensor holder rockably held by a contact sensor rotation shaft regulated in a thickness-wise direction of an original by a contact sensor holder rotation shaft holding portion of the frame and adapted to hold a second contact sensor in a confronting relation to the original convey roller. The second contact sensor is urged against the original convey roller by an urging spring.

  • Patent number: 5749570
    Abstract: The present invention provides a sheet conveying apparatus comprising a first rotary member for conveying a sheet, and a second rotary member disposed at a downstream side of the first rotary member in a sheet conveying direction and adapted to convey the sheet. It further comprises a first mode in which the first rotary member is rotated and the second rotary member is stopped, and a second mode in which the first and second rotary members are rotated. In a condition that the first rotary member is continuously rotated in one direction, the first mode is changed to the second mode.

  • Patent number: 5036319
    Abstract: An magnetic encoder includes a multipolar magnetic body having a row of alternate North and South poles of equal widths, and a magnetoresistive element diposed in confrontation to the multipolar magnetic body. The magnetoresistive element includes at least one A phase magnetoresistive element member and at least one B phase magnetoresisitve element disposed in juxtaposition over ##EQU1## where n is an integer greater than or equal to 1, and .lambda. is a width of each individual pole of the multiplar magnetic body. Each of the A phase magnetoresistive element members and the B phase magnetoresistive element member has a group of series connected linear conductors arranged side-by-side into a comb-like shape.
