Abstract
A controller moves a scanner at least to the farthest end portion of an original document placed on a platen in a forward moving action, and the original document is scanned in a reverse moving action of the scanner. In the case when an original document is fed by an original document feed device onto the platen, the scanner is started for a forward movement before the original document feeding operation is completed.
Claims18
A scanning device which is capable of performing a scanning operation by a first mode for scanning an original document directly placed on an original document table and a second mode for scanning an original document placed on the original document table wherein an original document is fed and placed on a predetermined position of the original document table by an original document feeder, comprising:
- a scanner which is capable of moving in reciprocating motion, wherein the scanner is moved forward to a farthest end portion of the original document from a standard position of the scanner passing through the original document placed on the original document table, and scans the original document in a reverse movement toward the standard position to read the original document;
- a mode changer for changing over between said first mode and said second mode;
- and
- a controller for controlling the scanner to start a forward movement before an original document is placed on a predetermined position of the original document table when said second mode is selected.
A scanning device comprising:
- an original document feeder for feeding an original document to a predetermined position on an original document table;
- a scanner which is capable of moving in reciprocating motion, wherein the scanner is moved forward to a farthest end portion of the original document from a standard position of the scanner passing through the original document placed on the original document table, and scans the original document in a reverse movement toward the standard position to read the original document;
- and
- a controller for starting a forward movement of the scanner before the original document is placed on the predetermined position of the original document table.
A copying machine which is provided with a first mode for copying an original document directly placed on an original document table, and a second mode for copying an original document placed on the original document table wherein an original document is fed and placed on a predetermined position of the original document table by an original document feeder, comprising:
- a scanner which is capable of moving in reciprocating motion, wherein the scanner is moved forward to a farthest end portion of the original document from a standard position of the scanner passing through the original document placed on the original document table, and scans the original document in a reverse movement toward the standard position to read the original document;
- a mode changer for changing over between said first mode and said second mode;
- and
- a controller for controlling the scanner to start a forward movement before an original document is placed on a predetermined position of the original document table when said second mode is selected.
A scanning device comprising:
- an original document feeder for feeding an original document placed on a sheet feed tray to a predetermined position on an original document table;
- a scanner which is capable of moving in reciprocating motion under and in parallel with the original document table wherein the scanner is moved forward at least to a farthest end portion of an original document from a retracted position where the scanner is positioned when not operated, and scans the original document in a reverse movement toward the retracted position;
- and
- a controller for starting a forward movement of the scanner to a predetermined position when a first size original document is placed on the sheet feed tray to be ready for a sheet feeding operation, wherein the predetermined position is a suitable position for starting to scan the first size document.
A method of scanning an original document by a scanning device which is provided with an original document feeder for feeding and placing an original document onto a predetermined position on an original document table, and a scanner which is movable in a reciprocating motion, wherein the scanner is moved forward at least to a farthest end portion of the original document from a standard position of the scanner passing through the original document, and scans the original document in a reverse movement toward the standard position to read the original document, comprising the following steps of:
- a first step for starting an original document feeding of the original document feeder;
- a second step for starting a forward movement of the scanner before completion of said original document feeding;
- and
- a third step for stopping the scanner after the completion of said original document feeding, and starting a reverse movement of the scanner.
