Reading apparatus that reads original sheet while conveying the same

摘要

In a reading apparatus, a control device is configured to: acquire a conveyance path switching information indicating whether a conveyance path switching unit has switched a conveyance path to a first conveyance path or a second conveyance path; judge, based on detection results by a width detecting unit, whether a type of an original sheet that is currently placed on an original sheet placing unit and that is not yet conveyed by a conveyance unit from the original sheet placing unit is a first type or a second type; and determine, based on both of the conveyance path switching information and the type of the not-yet-conveyed original sheet, whether the conveyance unit should stop conveyance of a preceding original sheet that the conveyance unit is currently conveying.

1. An image reading apparatus comprising:
an original sheet placing unit; a width detecting unit configured to detect a width of an original sheet that is placed on the original sheet placing unit; a conveyance unit configured to convey the original sheet from the original sheet placing unit; a reading unit configured to read the original sheet that is being conveyed by the conveyance unit; a conveyance path switching unit configured to switch, between a first conveyance path and a second conveyance path, a conveyance path to which the conveyance unit is to guide the original sheet, the first conveyance path leading to a first discharge port, the second conveyance path leading to a second discharge port, a width of the second discharge port defined in a width direction of the original sheet being smaller than a width of the first discharge port defined in the width direction of the original sheet; and a control device configured to:
acquire conveyance path switching information indicating whether the conveyance path switching unit has switched the conveyance path to the first conveyance path or the second conveyance path;judge, based on detection results by the width detecting unit, whether a type of an original sheet that is currently placed on the original sheet placing unit and that is not yet conveyed by the conveyance unit from the original sheet placing unit is a first type or a second type, first type original sheets having widths greater than or equal to a prescribed reference width, second type original sheets having widths smaller than the prescribed reference width, the prescribed reference width being equal to the width of the second discharge port; anddetermine, based on both of the conveyance path switching information and the type of the not-yet-conveyed original sheet, whether the conveyance unit should stop conveyance of a preceding original sheet that the conveyance unit is currently conveying.
