    Abstract: A closed loop direct position feedback control method and recording apparatus for producing on a recording medium a plurality of successive print lines or otherwise component images. An appendant demarcation device provides for the proper abutting and spacing of each independent print character. The apparatus includes a mechanism (18) for transporting the medium along a path orthogonal to the print head (12), which produces single lines or swaths (3) of print in conjunction with the indexed advance of the medium relative to the print head (12). The transport mechanism (18) is operative to advance a first print line or swath through the recording station (12) to form a first print line, to identify and store the position coordinates of each print line or swath (3), and to advance the recording medium for successive line or swath printing (3). The direct position feedback control apparatus also includes a demarcation sensing and printing device (20), (33) for relative positioning, whereby the distance between the location of any sensed or printed demarcation reference and the next successive print line is controlled such that each print line will neglect the positioning error in any previous print line or swath.

    Abstract: The image reading apparatus conveys a reading unit or a document to read the document. Conveyance is implemented by motor control based on a target position trajectory. The reading unit reads the document each time a line start signal is inputted. When a predetermined condition is satisfied, the reading operation is invalidated. A conveyance position at a timing to start the first reading operation invalidated is specified as an interrupted position. The object is arranged at a conveyance restart position moved back from the interrupted position. A target position trajectory is newly set. A conveyance time from the conveyance restart position to the interrupted position defined by the target position trajectory is an integral multiple of an output cycle of the line start signal. The motor control based on the target position trajectory is started at a timing coinciding with an output timing of the line start signal.

    Abstract: PROBLEM TO BE SOLVED: To provide a technology to resume reading at an appropriate point of time even if the resolution of an encoder is inferior to a line internal. SOLUTION: A multi-functional apparatus stops and resumes a reading operation according to the free space of a buffer. Before suspending reading, however, a period of time elapsing between an input of an edge detection signal of the encoder and an input of a line start signal is measured by an N counter, and at the same time, the current position of a transferred object is detected by a position counter based on the edge detection signal. When a req_stop signal is transitted to a value of 1, an offset time wait_cnt is set (for example, set to N7) based on the period of time (N7) measured by the N counter, and a value (k) outputted from the position counter at this time is set as a resumption reference position. When resuming reading, the line start signal is inputted into a CCD line sensor when the offset time has elapsed since the point when the transferred object has arrived at the resumption reference position (k), and reading is resumed at this point of time.
