Abstract

The present invention is directed to an image reading apparatus provided with an automatic document feeder (hereinafter referred to as an ADF). The apparatus enables registration of image data as one piece of data even when a document is read as a number of bundles (each bundle includes at least one page and is not more than the loading capacity of the ADF). Owing to this, when document images are divided into two or more bundles for successive reading, different read settings can be determined for the different bundles.

Claims

1. An image reading apparatus comprising:

setting means for setting a sequential document in units of one bundle;

settings-entering means for entering read settings for the document set by the setting means;

reading means for sequentially reading each bundle of the document set by the setting means in units of one page on the basis of the read settings entered by the settings-entering means;

recording means for recording image data on the document read by the reading means such that the image data corresponding to one bundle are recorded together; and

processing means, operating when abnormality occurs during read processing which the reading means performs with respect to one of the bundles of the document, for deleting from the recording means image data corresponding to a bundle for which the abnormality occurs, and for restoring the bundle to an original state.

2. An image reading apparatus comprising:

setting means for setting a sequential document in units of one bundle;

settings-entering means for entering read settings for the document set by the setting means;

reading means for sequentially reading each bundle of the document set by the setting means in units of one page on the basis of the read settings entered by the settings-entering means;

recording means for recording image data on the document read by the reading means such that the image data corresponding to one bundle are recorded together;

alteration means for altering the read settings entered by the settings-entering means when a second or subsequent bundles of the document are set by the setting means; and

processing means for causing the reading means to read the document set by the setting means in units of one page and for causing resultant read images to be recorded by the recording means,

wherein the read settings entered by the settings-entering means include settings regarding a read mode, a color mode, a resolution, a document size, a double/single-sided mode and an image rotation.

3. An image reading apparatus comprising:

setting means for setting a sequential document in units of one bundle;

settings-entering means for entering read settings for the document set by the setting means;

reading means for sequentially reading each bundle of the document set by the setting means in units of one page on the basis of the read settings entered by the settings-entering means;

recording means for recording image data on the document read by the reading means such that the image data corresponding to one bundle are recorded together;

first alteration means for altering the read settings entered by the settings-entering means when the setting means sets a second and subsequent bundles of the document;

first processing means for causing the reading means to read the document set by the setting means such that the document is read in units of one page on the basis of the read settings altered by the first alteration means, and for controlling the recording means to record read images;

output means for outputting read results which represent how the reading means reads each bundle of the document and also outputting recording results which represent how the recording means operates;

designation means for designating an alteration of an order in which the image data recorded by the recording means and corresponding to the bundles of the document are arranged;

second alternation means for altering an order in which the image data recorded by the recording means and corresponding to the bundles of the document are arranged; and

second processing means, operating when abnormality occurs during read processing which the reading means performs with respect to one of the bundles of the document, for deleting from the recording means image data corresponding to a bundle for which the abnormality occurs, and for restoring the bundle to the original state.
