According to the first aspect of the present invention, when it is detected that the image information reaches the end of the document, the image information is automatically scaled and shifted, and a margin is automatically set at the end of the recording medium. Form.

According to the second aspect of the invention, all the image information is automatically recorded on the recording medium by the document size information, the recording medium size information, and the image forming area information.

[0010]

Embodiments of the image recording apparatus of the present invention will be described below. FIG. 1 is a schematic configuration diagram of an image recording apparatus.

In this embodiment, a copying machine is shown as the image recording apparatus 1. The image recording apparatus 1 is provided with an automatic document feeder 2. The automatic document feeding unit 2 has an automatic document feeding unit A that automatically feeds a document K including a document tray 3, a feeding roller 4, a take-out table 5, and the like. The automatic document feeder A automatically feeds the documents K set on the document tray 3 one by one by driving the conveying rollers 4, and picks up the documents whose images have been read. Send it onto the stand 5.

The image recording apparatus 1 is also provided with an image reading section 10 for optically reading the image information of the document K. The image reading unit 10 has an image reading unit B that optically reads the image information of the fed document K. The light source 11 that constitutes the image reading unit B reciprocates to a position below the document mounting glass 6. A light source 11 that is operably arranged and that reciprocates
Illuminates the original on the original placing glass 6, and the reflected light is transmitted through the optical system including the mirrors 12 to 14 and the lens 15 to C
It is optically read by the CD 16.

The image information read by the CCD 16 is sent to the image editing control means 20 for editing the image,
The image is edited by the image editing control means 20, and the image output unit 3
At 0, the image is output to the recording medium F and the image information is recorded.

The image editing control means 20 receives the image forming area information from the determining means 40 for detecting and determining the image forming area on the original K, and the original size information from the original size detecting means 41 for detecting the size of the original K. The recording medium size information is input from the recording medium size detection unit 42 that detects the size of the recording medium F.

A margin setting automatic variable shift mode setting means 43 is connected to the image editing control means 20, and the margin setting automatic variable shift mode is set by the margin setting automatic variable shift mode setting means 43. Be done.

In the margin setting automatic variable shift mode, when the image editing control means 20 detects from the discriminating means 40 that there is image information up to the edge of the document K based on the image forming area information, the image information is automatically set. Is controlled to perform variable power shift, and a margin is automatically formed at the end of the recording medium F.

Further, the image editing control means 20 is automatically operated by the document size information from the document size detecting means 41, the recording medium size information from the recording medium size detecting means 42, and the image forming area information from the discriminating means 40. It is set so that all image information is recorded on the recording medium F.

Next, an embodiment of recording image information of a document in the margin setting automatic variable shift mode will be described more concretely with reference to FIGS. 1 and 2.

That is, the image reading means B optically reads the image information of the document K by the light source 11 such as a halogen lamp,
The image information of the document K is read by converting it into an electric digital signal by the CCD 16.

The image information obtained by the image reading means B is
The discriminating means 40 discriminates the original image region, up to which region. For example, as shown in FIGS. 2A and 2B, it is determined that the first original has an image on the entire surface, and
Although it is determined that the first original has a margin and the third original already has a margin, in the embodiment of FIG. 2A, the shift is performed to the minus side to determine the enlargement. Two
In the example of (b), it is determined that the shift is not performed.

The original size detecting means 41 is a portion for detecting the size of the paper of the original K and sends the original size information to the image editing control means 20 before the image forming process. For example,
When the document is fed by the automatic document feeder A, a method of detecting the length of the document based on the time during which the document is being fed or a plurality of optical sensors provided below the document placing glass 6 is used.

Margin setting automatic variable shift mode setting means 4
In 3, the general setting of the copying conditions is performed, and the setting of whether or not the present invention is automatically performed and the margin amount when the setting is set are, for example, 5 mm, 10 mm, 15 mm, 20 m.
m, 25 mm, etc. can be set in multiple stages.

The image edit control means 20 receives the document size information from the document size detecting means 41, the recording medium size information from the recording medium size detecting means 42, and the image forming area information from the discriminating means 40. The number of image shifts and the amount of magnification change for securing the set margin amount are calculated for each document. For example, as shown in FIGS. 2A and 2B, since the first original has an image on the entire surface, it is shifted and reduced to 0.95 times and recorded, and the second original is printed. Already has a margin, it is shifted and recorded at 1.00 times, and the third original has a margin already. However, in the embodiment of FIG. 2A, the shift is performed to the minus side. It was recorded at a magnification of 41 times, and
In the example of (b), it is recorded without being shifted and at 1.00 times.

The image output unit 30 executes the image forming process, but receives the instruction from the image editing control means 20 and executes the shift amount switching and the variable amount switching. The switching of the shift amount is performed by an image writing start signal in the sub-scanning direction or a switching of the recording medium F and image alignment timing. Switching of the variable magnification amount corresponds to switching of the laser writing degree and density in the sub-scanning direction, and switching of the speed of the photosensitive member in the main scanning direction.

[0025]

As described above, according to the first aspect of the present invention, when it is detected that the image information reaches the end of the document, the image information is automatically scaled and shifted, and the image is recorded on the recording medium. Since the margins are automatically formed at the edges of the document, the inconvenience of the user individually designating the margin formation is eliminated, and by appropriately determining the image information range of the document, an appropriate scaling shift amount can be set for each document. It can be automatically selected and controlled.

According to the second aspect of the present invention, since all the image information is automatically recorded on the recording medium by the document size information, the recording medium size information, and the image forming area information, the user can copy each image one by one. By automatically controlling the reduction shift amount in the image area on the document without setting the reduction shift amount for each document, an appropriate edit value is always set for each document, and the recording medium after recording is recorded. The binding amount on the upper side can always be made uniform. Further, for example, when the image information on the document has a blank space formed from the beginning, the correction value automatically becomes zero, and the user does not feel uncomfortable.
