Abstract
An image reading apparatus includes a discharging unit that discharges an original document read by a reading unit to a stacker, in which a controller of the image reading apparatus discharges a first original document at a first transporting speed caused when the original document specified from an original document length measured by the measuring unit is the first original document and discharges a second original document at a second transporting speed slower than the first transporting speed caused when the original document is the second original document longer than the first original document.
Claims17
An image reading apparatus comprising:
- a feeding unit that feeds an original document in an order from a lowest original document one by one by the feeding unit;
- a transporting unit that transports the original document;
- a reading unit that reads an image of the original document;
- a measuring unit that measures a length of the original document;
- a discharging unit that discharges the original document after being read by the reading unit;
- a stacker that receives the discharged original document;
- and
- a controller that controls the transporting unit and the discharging unit,
- wherein the controller causes a first original document to be discharged at a first transporting speed when the original document being specified from an original document length measured by the measuring unit is the first original document, and causes a second original document to be discharged at a second transporting speed slower than the first transporting speed when the original document is specified the second original document longer than the first original document, and
- wherein the controller causes the second original document to be transported at a reading speed while the reading unit reads the second original document in a case in which the original document is the second original document based on a measured result of the measuring unit and decelerates a transporting speed of the second original document to the second transporting speed from the reading speed when reading by the reading unit is completed, wherein the reading speed is equal to the first transporting speed, and
- wherein the controller controls the feeding unit and accelerates a feeding speed from a first feeding speed associated with the original document to a second feeding speed, higher than the first feeding speed, to feed the second original document toward the reading unit for at least a portion of a time when the original document is being discharged from the discharging unit, at least a portion of the second original document being read by the reading unit while the original document is discharged by the discharging unit.

An image reading apparatus comprising:
- a feed tray that loads on a plurality of original documents;
- a feeding unit that feeds an original document in an order from a lowest original document one by one by the feeding unit;
- a transporting unit that transports the original document;
- a reading unit that reads an image of the original document;
- a measuring unit that measures a length of the original document, wherein the measuring unit is disposed inside the image reading apparatus between the reading unit and the feed tray of the image reading apparatus;
- a discharging unit that discharges the original document after being read by the reading unit;
- a stacker that receives the discharged original document;
- and
- a controller that controls the transporting unit and the discharging unit,
- wherein the reading unit is disposed between the feed tray and the discharging unit;
- wherein the controller causes a first original document to be discharged at a first transporting speed when the original document being specified from an original document length measured by the measuring unit is the first original document, and causes a second original document to be discharged at a second transporting speed slower than the first transporting speed when the original document is specified the second original document longer than the first original document,
- wherein the controller causes the second original document to be transported at a reading speed while the reading unit reads the second original document in a case in which the original document is the second original document based on a measured result of the measuring unit and decelerates a transporting speed of the second original document to the second transporting speed from the reading speed when reading by the reading unit is completed, wherein the reading speed is equal to the first transporting speed, and
- wherein the controller controls the feeding unit and accelerates a feeding speed from a first feeding speed associated with the original document to a second feeding speed, higher than the first feeding speed, to feed the second original document toward the reading unit for at least a portion of a time when the original document is being discharged from the discharging unit, at least a portion of the second original document being read by the reading unit while the original document is discharged by the discharging unit.
10 more elements
An image reading apparatus comprising:
- a transporting unit that transports an original document;
- a reading unit that reads an image of the original document;
- a measuring unit that measures a length of the original document;
- a discharging unit that discharges the original document at a predetermined discharging speed from a discharge port in a discharging direction after being read by the reading unit;
- a stacker that receives the discharged original document;
- a stopper that is provided in a distal end portion of the stacker and regulates movement of the discharged original document in the discharging direction by coming into contact with a leading edge of the original document in the discharging direction;
- and
- a controller that controls the transporting unit and the discharging unit,
- wherein the controller discharges a first original document after being read by the reading unit, without reducing the predetermined discharged speed, when a length of the first original document measured by the measuring unit is shorter than a length of the stacker, and discharges a second original document after being read by the reading unit by reducing the predetermined discharging speed when a length of the second original document measured by the measuring unit is longer than the length of the stacker.
