For this purpose, the surface of the print medium placed on the belt and the surface of the belt are detected to acquire the moving distance or moving speed of the print medium. Based on the moving distance or moving speed thus obtained, the driving of the belt is controlled. Even in a situation where the object being detected switches from the print medium to the belt in the middle of the conveying operation, the measurement of the moving distance can be performed without interruption by the same detection method using the same optical sensor unit. | 12-31-2009 |
| 20100044947 | RECORDING APPARATUS AND RECORDING METHOD - A recording apparatus includes a conveying roller and an ejection roller for conveying a recording medium. The recording apparatus also includes a controller which controls the conveying roller and the ejection roller. The controller selectively performs a conveyance control process for the rollers when the recording medium leaves the conveying roller. | 02-25-2010 |
| 20100044959 | PRINTING APPARATUS AND METHOD FOR DETECTING ORIGIN OF CONVEYING ROLLER - The present invention is to provide a printing apparatus capable of correctly detecting an origin of a conveying roller for conveying a print medium at the time of its rotation with a simple configuration that does not accompany an increase of cost. For this purpose, the printing apparatus is equipped with a lock mechanism (a lock link lever) for stopping rotation of the conveying roller at a predetermined rotational position and saves a count value of a rotation amount of the conveying roller when the conveying roller is locked by the lock mechanism concerned as origin information. After this, driving of the conveying roller is controlled based on the saved origin information and a phase of rotation of the conveying roller obtained from the count value of the conveying roller. | 02-25-2010 |
| 20100045725 | APPARATUS AND METHOD FOR RECORDING - A recording apparatus has a controller that controls a conveying roller and a discharge roller for conveying a recording medium. The controller controls the rotation phases of the conveying roller and the discharge roller when the recording medium leaves the conveying roller before the recording medium enters the conveying roller. | 02-25-2010 |
| 20100066782 | PRINTING APPARATUS AND PRINTING METHOD - A printing apparatus including a conveyance mechanism configured to convey a sheet in a predetermined direction, a printing unit configured to print an image on the sheet, a direct sensor having an image pickup device configured to image the sheet, which is used to sense movement of the sheet by signal processing of an output from the image pickup device, a movement mechanism configured to move the image pickup device in a direction including a component of the predetermined direction, and a control unit configured to control the conveyance mechanism, the printing unit, and the movement mechanism. | 03-18-2010 |
| 20100134551 | PRINTING APPARATUS - A printing apparatus includes a plurality of image sensors imaging a sheet to be conveyed, and a direct sensor unit performing the signal processing of the outputs of the image sensors to detect the movement of the sheet. Here, the plurality of image sensors are provided on the carriage at least at two positions with at least the recording element array diagonally put between the two positions. The plurality of image sensors can image the sheet at two positions separated in a main scan direction and a sub-scan direction. | 06-03-2010 |
| 20100134552 | PRINTING APPARATUS - Provided is a printing apparatus including a sensor unit for measuring a moving state of a sheet by optically detecting a surface of the sheet conveyed by a conveying unit. The sensor unit measures and compares the moving states of the sheet at a first measurement position and a second measurement position which are distinct from each other in a main scanning direction, to thereby obtain information on a skew state of a skew component of the moving sheet. | 06-03-2010 |
| 20100148426 | PRINTING APPARATUS - Provided is a printing apparatus, including a sensor unit which optically detects, at a measurement position, a surface of a sheet, for measuring a moving state of the sheet. The sensor unit measures the moving state of the sheet when the sheet is located at the measurement position, and measures a moving state of a surface of the rotary member when the sheet is not located at the measurement position. | 06-17-2010 |
| 20100149245 | RECORDING APPARATUS AND RECORDING METHOD - In the present invention, a conveying operation of a recording medium is controlled on the basis of a first correction value and a second correction value. The first correction value is used for correcting a conveying amount when the recording medium disengages from a first conveying roller, and the second correction value is used for correcting the phase of the first conveying roller and a second conveying roller when the recording medium disengages from the first conveying roller before the recording medium is nipped by the first conveying roller. | 06-17-2010 |
