摘要： An image recording apparatus includes a conveyance roller which conveys the recording medium, a drive source for rotating the conveyance roller, a print head and a carriage mounted with the print head. The carriage includes an abutment portion. The image recording apparatus further includes a carriage position detector which detects a position of the carriage in a movement direction of the carriage and still further includes a rotating body which rotates in synchronization with the conveyance roller. The rotating body includes a reference portion which protrudes or depresses in the movement direction at a predetermined rotation phase of the rotating body and abut with the reference portion. Moreover, the image recording apparatus includes an origin determination section which, based on a result of the detection by the carriage position detector, determines an origin position of a rotation phase of the conveyance roller.

摘要： PROBLEM TO BE SOLVED: To provide an image input device provided with an image sensor, wherein the image quality of an image to be read is improved.
SOLUTION: The image input device for reading an original by moving a carriage mounted with the image sensor 202 and 3-color LEDs in a subscanning direction of the original by a motor 300 includes: a controller 100 for controlling driving of the motor 300, operations of the image sensor 202, and turning on/off of the LEDs; and an encoder 400 for outputting an edge signal to the controller 100 when detecting a moving amount of the carriage by one subscanning line. Then every time the controller 100 receives the edge signal from the encoder 400, the controller 100 sequentially turns on/off the 3-color LEDs, sequentially reads electric charges stored in the image sensor 202 while the respective LEDs are turned on, and thereafter discards the electric charges stored in the image sensor 202 until the controller 100 receives a succeeding edge signal.

摘要： PROBLEM TO BE SOLVED: To improve a design flexibility for an image reading apparatus which performs a reading operation matched with the speed of an object to be conveyed.
SOLUTION: The image reading apparatus includes a line sensor for reading a document in a main scanning direction for one line by executing a reading operation each time a line-start signal is input, conveys a reading unit or the document in a sub scanning direction and repeatedly inputs the line-start signal, thereby reading the overall document for each line. Specifically, the period of an output signal from an encoder mounted on a motor for driving an object to be conveyed, is measured and the latest measurement value is stored and held. Each time the lapse of a time from the final input of the line-start signal to the line sensor becomes equal to or longer than a time calculated by multiplying the latest measurement by a correction coefficient, the line-start signal is input to the line sensor. The correction coefficient is set to a value calculated by dividing encoder resolution by a reading resolution, the encoder resolution being the number of pulses which are output from the encoder when the object to be conveyed is moved for a unit length in the sub scanning direction.

摘要： 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.

摘要： PROBLEM TO BE SOLVED: To generate re-sampling line image data assembly within a desired sampling range by receiving line scan data assembly on a camera rate out of a line scan camera.
SOLUTION: A method for re-sampling line scan data background includes an assembly receiving step, measured value receiving step, and re-sampling step. First, the line scan data assembly is received on the camera rate out of the line scan camera. Next, the measured value of relative speed is received between the line scan camera and an object which is shown up on an image by the line scan camera. Then, the re-sampling line scan data assembly step comes for generating re-sampling line image data assembly within the desired sampling range. The re-sampling is a function on the camera rate, the measured value of relative speed, and the desired sampling range. The re-sampling is adjusted depending on changes of the relative speed for generating true exposing data.
