摘要： In an image-recording device, a feeding roller feeds recording media one at a time from a media-accommodating unit along a conveying path. A pair of registration rollers is disposed on the conveying path and conveys the recording medium fed by the feeding roller to an image-recording region. The registration rollers include a drive roller. A carriage reciprocates in the image-recoding region in a direction intersecting a conveying direction in which the recording medium is conveyed. A recording head is mounted on the carriage. A drive transmission switching unit is disposed outside the image-recording region on one end with respect to the reciprocating direction of the carriage and switches a combination of rotating and halted states of the drive roller in the registration rollers and the feeding roller between a continuous feeding mode and an intermittent feeding mode. A controlling unit activates the drive transmission switching unit by moving the carriage to selectively switch between the continuous feeding mode and the intermittent feeding mode.

摘要： To provide a sheet supply device including a long life sheet supply roller. A large radius portion 10a of a sheet supply roller 10 is gradually abraded in association with passage of operation time. Protrusions 12a of an idle roller 12 initially contact a rotational shaft 14 without forming any play between the protrusions 12a and the rotational shaft 14. However, friction force generated between the tips of the protrusions 12 and the rotational shaft 14 wears down the protrusions 12a. As a result, a difference between the radius of the large radius portion 10a and the radius of the idle roller 12 will be hardly decreased even after a cumulative operation time. Therefore, even after the abrasion progresses, sheet supply operations will be operated properly.
摘要翻译：提供一种包括长寿命供纸辊的供纸装置。供纸辊10的大半径部分10a随着操作时间的流逝而逐渐磨损。空转辊12的突起12a最初接触旋转轴14，而不会在突起12a和旋转轴14之间形成任何间隙。然而，突起12和旋转轴14的尖端之间产生的摩擦力使突起12a磨损。结果，即使在累积操作时间之后，大半径部分10a的半径和空转辊12的半径之间的差几乎也不会减小。因此，即使在磨损进行之后，片材供给操作也将正常运行。

摘要： A sheet feeder provided in an image forming device and includes a sheet feed roller, a pair of rollers provided at both ends of the sheet feed roller and rotatable independent of the sheet feed roller, and a separation pad provided in confronting relation to the sheet feed roller and the pair of rollers. The sheet feed roller has a circumferential surface portion and a cut-out surface portion. When the cut-out surface portion is opposite a sheet and the separating pad, outer peripheral surface portions of the pair of rollers contact the sheet at approximately the same level position that the circumferential surface portion of the feed roller contacts the sheet. This maintains the separating pad in approximately the same position.

摘要： A sheet feeder provided in an image forming device and includes a sheet feed roller, a pair of collars provided at both ends of the sheet feed roller and rotatable independent of the sheet feed roller, and a separation pad provided in confronting relation to the sheet feed roller and the pair of collars. The sheet feed roller has a cylindrical roller having a diameter smaller than that of the collar and a roller shaft. An irregular diameter sleeve including first and second radius portions is mounted on the roller shaft, and the collar is loosely rotatable on the irregular diameter sleeve. The first radius portion has a first radius greater than a second radius of the second radius portion. When the first radius portion is angularly rotated to a position in confrontation with the separation pad, a distance between an axis of the roller shaft and the lower end of the collar is greater than the radius of the feed roller. When the second radius portion is angularly rotated to the position in confrontation with the separation pad, the lower end of the collar can be moved upwardly, so that the sheet feed roller can perform sheet nipping relative to the separation pad.

摘要： A sheet feed device has a tray with holding surface for holding sheets, a feed unit for feeding sheets from the tray, and a separation plate. The separation plate has an inclined surface and two or more separation portions that separate a sheet from the sheets held in the tray. At least one of the separation portions projects a first distance from the inclined surface. The separation plate also has a projection positioned on the inclined surface that projects a second distance from the inclined surface. The second distance is greater than the first distance. A first of the separation portions is positioned upstream of the particular projection in the sheet feed direction, and a second of the separation portions positioned downstream of the particular projection in the sheet feed direction.

摘要： An image recording device is provided, having a recording unit configured to record an image on a sheet, and a tray disposed below the recording unit. The tray includes a sheet holding surface configured to hold the sheet. Additionally, the image recording device includes a sheet feeder disposed between the recording unit and the tray. The sheet feeder includes a roller for feeding the sheet from the tray. The roller is configured to move between a first roller position in which the roller contacts the sheet holding surface of the tray and a second roller position in which the roller is separated from the sheet holding surface. A return guide, disposed between the recording unit and the sheet feeder, defines a second conveying path to guide the sheet having an image recorded on one side thereof back to the feed guide. The return guide has a first opening configured to accommodate the roller of the sheet feeder when the roller is in the second roller position.
