摘要： A first feeder contacts a first surface of a first sheet held in a first tray and feeds the first sheet toward a recording unit. A second feeder contacts a first surface of a second sheet held in a second tray and feeds the second sheet toward the recording unit. An inner member is disposed above a standing plate. An outer member comprises an upstream portion opposing the standing plate, and a downstream portion opposing the inner member. The inner member guides the first surface of the first sheet and the first surface of the second sheet. The standing plate guides the first surface of the second sheet. The upstream portion of the outer member guides a second surface of the second sheet, and the downstream portion guides a second surface of the first sheet and the second surface of the second sheet. The standing plate moves relative to the outer member.

摘要： An image recording apparatus includes a body, a tray, a moving member, an actuator, a sensor, a reference position moving mechanism and a control unit. The moving member is movable to a first position, a second position, a third position and a reference position. The actuator moves the moving member to the first position, the second position and the third position. The sensor outputs an ON signal or an OFF signal based on positions of the moving member, the positions including the first position, the second position, the third position and the reference position. The reference position moving mechanism moves the moving member to the reference position. The control unit determines a detection position to be detected based on a change of the ON signal and the OFF signal of the sensor when the moving member is moved between the detection position and the reference position by the reference position moving mechanism. The control unit further determines that a recording medium held on the tray is the first recording medium when the detection position is the first position and that a recording medium held on the tray is the second recording medium when the detection position is the second position.
摘要翻译：图像记录装置包括主体，托盘，移动部件，致动器，传感器，基准位置移动机构和控制单元。移动构件可移动到第一位置，第二位置，第三位置和参考位置。致动器将移动构件移动到第一位置，第二位置和第三位置。传感器基于移动构件的位置，包括第一位置，第二位置，第三位置和基准位置的位置输出ON信号或OFF信号。参考位置移动机构将移动构件移动到参考位置。当移动构件通过基准位置移动机构在检测位置和基准位置之间移动时，控制单元基于传感器的ON信号和OFF信号的改变来确定要检测的检测位置。当检测位置是第一位置时，控制单元还确定保持在托盘上的记录介质是第一记录介质，并且当检测位置是第二位置时，保持在托盘上的记录介质是第二记录介质。

摘要： A sheet conveyer device to convey a sheet in a conveyer path, including a first roller pair arranged in an intermediate position in the conveyer path, a feeder to feed the sheet toward the first roller pair during a feeding operation, a discharge portion, on which the sheet is discharged, a second roller pair arranged in the conveyer path in a position closer to the discharge portion than the first roller pair, a control unit to control the first and the second roller pairs to rotate synchronously, and a judging system to judge whether a sheet feeding error has occurred in the feeder, is provided. The control unit controls the first and the second roller pairs to rotate synchronously in a second direction during the feeding operation and in a first direction when the judging system judges that the sheet feeding error has occurred during the feeding operation.

摘要： An image recording device comprises a housing, a sheet cassette, a recording unit, and a convey path defining member. The housing has an opening. The sheet cassette is configured to hold therein sheets and configured to be inserted into and removed from the housing through the opening. The recording unit is configured to record an image on a sheet conveyed from the sheet cassette along a convey path. The convey path defining member is configured to pivot, about a pivot shaft supported by the housing, between a guiding position for forming a guide surface that defines a part of the convey path, and an exposing position for exposing the part of the convey path to the opening. The convey path defining member is configured to pivot in response to insertion and removal of the sheet cassette.
