Conveying device and image recording apparatus

摘要

A conveying device includes: a conveyor for conveying a sheet; a path defining member having a first conveying surface that guides the sheet; and a sensor device for sensing the sheet. The sensor device includes: a sensor casing provided on the path defining member and including a second conveying surface that guides the sheet and a main wall whose outer surface is exposed from the path defining member and contiguous to the first conveying surface; a movable member including (i) a contact portion projecting to a second-conveying-surface side of the main wall through an opening formed in the main wall and (ii) a sensed portion located in the sensor casing and moved by the sheet conveyed on the second conveying surface while contacting the contact portion; and a signal output device, provided in the sensor casing, for sensing the sensed portion to output a signal related to its position.

主权项

1. A conveying device comprising:
a conveyor configured to convey a sheet in a conveying direction; a path defining member comprising a first conveying surface that guides the sheet conveyed by the conveyor; a sensor device configured to sense the sheet conveyed by the conveyor and comprising:
a sensor casing comprising a main wall and provided on the path defining member such that a guide portion, including a second conveying surface, provided on an outer surface of the main wall which is exposed from the path defining member is contiguous to the first conveying surface, the guide portion being configured to guide the sheet conveyed by the conveyor;a movable member comprising (i) a contact portion projecting to a side of the main wall on which the guide portion is located, through a casing opening formed in the main wall and (ii) a sensed portion which is located in the sensor casing and moved from a first position to a second position by movement of the sheet that is conveyed on the guide portion while contacting the contact portion; anda signal output device provided in the sensor casing and configured to sense a position of the sensed portion to output a signal related to the position of the sensed portion; a control board configured to control the conveyor; and a cable configured to connect the control board and the signal output device to each other, wherein the cable is located at a downstream end portion of the second conveying surface in the conveying direction and at a back of the second conveying surface in a direction intersecting the conveying direction, and the cable extends from a clearance between the path defining member and the sensor casing to a space located on an opposite side of the path defining member from the inner space thereof, and wherein the sensor casing comprises a partition located between the second conveying surface and the clearance and extending in a direction in which the cable extends.
