Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is based on the document size detection system that detects the document size detected by the first stage and the cassette size or automatic change that is determined by the automatic paper feeding mode according to the document size. The present invention relates to an image processing device that displays the selected cassette (and size) on the same plane in order to determine the double mode.

[Prior art and its problems]

Conventionally, some devices of this type are equipped with means for automatically selecting a paper cassette or automatically setting the transfer magnification according to the document size detected by the document size detection means, allowing the operator to transfer any size of document. The configuration is such that mode settings can be reduced by selecting either the paper feed cassette containing paper or the transfer magnification.

However, since the document size detection means does not have a means to display the detected document size, the cassette size or automatic magnification mode is determined based on the document size and the automatic paper feeding mode. In order to confirm the combination with the selected cassette size, an image forming operation must always be performed, and the operator must perform a trial copy.

[Purpose of the invention]

The present invention was developed to eliminate the above-mentioned drawbacks, and the cassette size or automatic magnification is determined by the document size detected by the document size detection means and the automatic paper feeding mode according to the document size. 1f14Ji to determine the mode! By providing a composite display section that displays the selected cassette size on the same plane, the operator can display the selected cassette in order to determine the cassette I size or automatic magnification mode in document rise and automatic paper feeding modes. An object of the present invention is to provide an image processing device that allows the size to be visually confirmed. The present invention will be explained below with reference to the drawings.

The document 31 is fed by the paper feed roller 41a and the transport roller 41b 1
When the paper is conveyed through the roller 41c, the paper is conveyed to a predetermined position by the belt 42, and then stopped. At this time, a copy start command is sent to the main control section of the device, which will be described later.
After the copy operation is completed, the data is deposited on the #JF output) ray 43. Note that when the original 31 passes through the paper feed sensor 44, the paper size can be detected by defining a horizontal direction perpendicular to the feeding direction of the original 31. Further, this automatic document feeder is constructed so that it can be installed in the main body in exchange for the document pressure plate 3 shown in FIG.

It is composed of a sub-control section 55 which sends a document size signal to the main control section 51, etc. 56 is a copy key, 57 is a document size detection star 1 and key which is the confirmation display command means of the present invention. 58 is the above-mentioned key. A display section that displays the document size detected by the line sensor 36 or the paper feed sensor 44, and is a display group 2T, 22 shown in FIG.
．． It is constituted by a composite display section 23.

Note that the image processing apparatus of the present invention has a transfer function based on the existing electrophotographic method. Furthermore, the cassette size is automatically selected in the automatic paper feeding mode, and the magnification is automatically set in the automatic magnification mode.

Next, the operation of determining the automatic magnification mode or the automatic paper feeding mode based on the document size detection operation by the line sensor 36 and paper feed sensor 44 will be explained in order. Note that the two systems of document size detection means can be freely selected according to the operator's will, and the two systems are automatically switched. That is, when using the automatic document feeder 54, the document size is detected by the paper feed sensor 44 in order to increase the copy speed, and the size of the document (such as a book) that cannot be loaded into the automatic document feeder 54 is detected. In this case, the line sensor 36 detects the document size. Furthermore, it is assumed that the manuscript 31 is a book.

Now, the operator selects the automatic paper feeding mode or the automatic magnification changing mode using key manual means (not shown) on the operation panel 11-, and one of the modes is determined. For example, when automatic paper feeding mode is selected, magnification information is then input manually. At this time, the cassette size of the selected paper feed cassette, for example B5, lights up in the display group 22, and the cassette area is displayed in the composite display group 23. After that, when the operator presses the copy key 56, the prescan is performed 11 to detect the document size, and the line sensor 36 receives the reflected light from the lamp 32, and the document information (document length (portrait/I length) is ), the original density 49) is collected, and the amplifier 5
2. It is sent to the input port of the main control section 51 via the A/D converter 53. The main control unit 57 determines the document size from the above document information.

From the output port of the IE control unit 51, the display group 2 on the operation panel 1 is displayed as a standard size, and the document area is displayed on the composite display unit 23 based on the size and orientation of the input document 31. do. Note that the document area display is displayed only during copying to prevent misidentification with the cassette area display. That is, while the document area display is a dynamic display such as a rotation display or a flashing display, the cassette area display is a static display so that the two can be distinguished. Thereby, by displaying the sizes and orientations of the document size and the cassette size in the same area on the composite display section 23, it becomes possible to more visually appeal to the operator about the copy mode.

- On the other hand, if the line sensor 3G detects a misplacement of the document 31 based on the prescan results, for example, if the document 31 is placed diagonally or the reference point is incorrect, the operation panel 1
A warning is displayed on the upper display (not shown). At this time, if the document 31 is simply placed misaligned in the scanning direction, the main control unit 51 controls the timing of registration rollers (not shown) in the paper feed system to automatically adjust the transfer start. Correct to.

Also, based on the pre-scan results, the line sensor 36 detects that the document 31 has been placed incorrectly, for example, the document 31 is placed horizontally instead of being placed vertically on the document table crow 2]. Display section on operation panel 1 (
(not shown).

Furthermore, based on the pre-scan results, the line sensor 36
If it is determined that this is a non-standard size document based on the relationship between the vertical and horizontal lengths of the original 31, the minimum fixed size (11 size) that satisfies the vertical and horizontal lengths of this original 11 x 331 is selected and displayed on the composite display section 23. >1, and the automatic magnification mode and automatic paper feeding mode can be determined according to the document size.

On the other hand, when the operator presses the document size detection star i key 57, the prescan operation or the automatic document feeder 1V154 is operated in the same way as normal operation, the document size is detected, and the composite display section 23 is displayed. In addition to displaying the image, setting operations in automatic magnification mode or automatic paper feeding mode are executed, and the control ends without performing image formation.

Next, the document size detection operation by the automatic document feeder 54 will be explained.

After the operator specifies either the portrait or landscape orientation of the document 31, the document 31 is loaded. Next, the paper feed sensor 44 senses the passage of the original 31, detects the length of the other one of the originals 31 which was not specified based on the passing time, and sends the detected length to the sub-control unit 55. Along with this, the sub-control unit 55 sends the detected document size to the main control unit 51. In response to this, the main control unit 51 displays the detected document size in the composite display t<++ 23. The subsequent operations are based on the operations performed by the line sensor 36.

Next, the detailed operation of the present invention will be explained with reference to the flowcharts of FIGS. 6(a) and 6(b). In addition,(
