Abstract

PURPOSE:To facilitate scanning for book copying by providing a means which selects optionally the order of scanning to a device which makes an optical scanning different in distance twice and copies different pictures. CONSTITUTION:A book 10 is opened and placed on platen glass 1 with the face down and the lengths of areas to be scanned are denoted as (r) and (l). Reflected light from the book 10 irradiated by a light source 2 is made incident on a photosensitive drum 9 for an electrostatic latent image by using the light source 2, a reflecting plate 13, mirrors 4, 5, 6, and 8, and a lens 7. A normal or setting-2 copy mode is selected with a changeover switch 12a on the console panel 12 of the image processor 11, and the order of scanning is specified with a changeover switch 12b to display a scanning surface specified with the changeover switch 12b. Consequently, when a book copy is taken, the book is set invariably in a specific direction regardless of its binding direction; and operator's trouble is eliminated and copying operation is performed accurately.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention is capable of copying two different copy image areas with one copy command.
The present invention relates to an image processing apparatus using a slit exposure method which has a so-called 1-set 2-copy function that can produce 2 copies.

[Prior art and its problems]

"1 set of 2 copies" means, for example, that the first half of an A3 original is copied on A4 transfer paper by one copy command (pressing the copy button) using A4 size paper as the transfer paper and A3 size paper as the original. This function allows you to obtain a total of two copies of A4 transfer paper on which the second half of an A3 original is copied.

This function is available when the book copy is pressed and the two-page spread is A.
This is convenient when copying one page of each page from a three-size book manuscript, that is, making an A4-size copy.

Conventionally, this type of apparatus always copies the front half of the document first, then the rear half. In other words, the first time the optical system scanned a scanning distance that was about half of the original, and the second time the optical system scanned a scanning distance that was approximately the same length as the original.

Now, when copying one page of each A4 size (A3 size spread) book, the copy paper is ejected face-up (printed side facing up), so the copy order is It is preferable to copy from the last page of the document.Considering the order of copying, it is better to copy the younger pages later, so set the tree in that direction on the platen glass of the device. What you need to pay attention to here is the way the wood is bound.In other words, when you open a book with right-hand binding, the younger pages are on the right side, and when you open a book with left-hand binding, the younger pages are on the right side. The other page is located on the left side.Generally, vertically written books are bound on the right, and horizontally written books are bound on the left.For this reason, when an open book is placed on the platen glass, the first page to be copied is fixed. (for example, copying the left-hand page when facing the operator first), if the book is bound on the left, it is sufficient to set the book on the platen glass in the forward direction as seen from the operator, but if the book is bound on the right, If so, the book must be set in the opposite direction (upside down) from the operator's perspective.In other words, it is necessary to consider the orientation of the book on the platen glass depending on how the book is bound.For this reason, the operator must constantly correct the orientation. Since the user is forced to do the same copying operation, there are problems such as a significant drop in copying efficiency and the need for troublesome and time-consuming work.

[Purpose of the invention]

This invention was made to solve the above problem, and allows an operator to arbitrarily specify the scanning order of the optical system for one image area in image processing in one set, two copies, one mode. An object of the present invention is to provide an image processing device that displays a scanning order by displaying a scanning order so that a book can always be set in one direction as viewed from an operator on a platen glass regardless of whether it is right-bound or left-bound.

〔Example〕

1 and 2 are a schematic configuration diagram and a plan view showing an embodiment of the present invention. In FIG. 1, 1 is a platen glass on which an original is placed, 2 is a halogen lamp for irradiating the original, and 3
is a reflective shade, 4 is the first mirror, 5 is the second mirror, 6 is the third mirror
A mirror, 7 is a projection lens, 8 is a fourth mirror, 9 is a photosensitive drum, 10 is a tree set on the platen glass 1, and r and Jl indicate the right page and left page of the tree 10, respectively.

In FIG. 2, 11 is an image processing device, 12 is an operation panel, 12a is a mode switch for switching between normal mode and 1 set 2 copy mode, and 12b is for specifying the scanning order while the mode switch 12a is operating. Scan order designation switch 13 is this scan order designation switch 1
A display device that displays a scanning plane specified by 2b on a liquid crystal display, 1
4 is an operator. In FIG. 1, 2 to 4 constitute the first mirror unit, and 5.6 constitutes the second mirror unit. 1st
When a document is scanned by the mirror unit, the second mirror unit is periodically scanned at half the speed of the first mirror unit. Furthermore, peripheral processing devices for the photosensitive drum 9 are omitted.

The operation will be explained below.

When the mode changeover switch 12a is in the OFF state, the image processing device 11 selects the normal mode and copies the original onto transfer paper fed from the selected cassette by the set number of sheets. This is a function of commonly used image processing devices. In addition to this function, the image processing apparatus 11 of the present invention has a function of executing the above-mentioned 1 set 2 copies by turning on the mode changeover switch 12a.

While the mode selection switch 12a is ON, that is, "1 set 2 copies", and the scanning order designation switch 12b
When a copy button (not shown) is pressed in the OFF state, optical scanning corresponding to the r portion of the book 10 is first performed to obtain a copy of the r portion. Once the optical system returns to the home position, the optical system continues scanning corresponding to the textuality to obtain a copy of the textuality. Note that the original irradiation halogen lamp 2 shown in FIG. The position of the second mirror 5, etc. indicates the home position of the optical system, and after completing the optical system scanning of the r portion, the optical system returns to the home position once. When scanning the text, the optical system also scans the r portion, but since the image of the r portion is unnecessary, the document irradiation halogen lamp 2 does not need to be turned on even if it is turned on. Alternatively, the charge on the photosensitive drum 9 corresponding to the r portion may be turned off, or the potential may be eliminated by a light irradiation means (not shown).

Now, when performing "one set, two copies" taking into account the binding direction of the book 10 (for example, right binding), the operator 14 first presses the mode changeover switch 12a, and then selects the text part using the scanning order designation switch 12b. When set to scan for the first time, a display as shown in FIG. 3(b) is displayed on the display 13. Here, when the copy button is pressed, the text is copied sequentially starting from the sentence part. Note that when the tree 10 is left-bound, if the scanning order designation switch 12b is set to scan the r section first, the display 1
3 as shown in FIG. 3(a). In this way, when the tree 10 is right-bound, by first copying the sentence part and then the r part, the spine of the tree 10 can be set so that it is always positioned in the forward direction as viewed from the operator 14.

In the above embodiment, a separate display 13 was provided to display the scan plane designated by the scan order designation switch 12b.
This function may be provided to the scanning order designation switch 12b. Furthermore, if the display method is displayed as "right binding" or "left binding", the operator 14's operational errors are reduced.

Next, the operation will be explained.

When commercial power AC is supplied to the main body of the apparatus, a microcomputer (not shown) is activated, and when a job switch (not shown) is turned on, the motor that drives the drum 22 is turned on, the exposure lamp 23 is turned on, and the shutter 45 is opened. , the corona charger 26 is turned on, rotates the drum 22, and cleans the drum 22. This removes residual toner, residual charges, and the like. When the fixing roller 40 reaches a fixable temperature by the internal heater, a copy enable signal is sent to the microcomputer, and the warm-up operation is completed. Next, the operator sets a desired operation mode, such as the number of copies, transfer magnification, etc., on the operation panel. After setting this operation mode,
When the copy start key is pressed, the exposure lamp 23 emits light and the transfer operation starts. At this time, the platen 21 reciprocates with the document placed thereon. During this time, reflected light from the original is imaged on the drum 22 via mirrors 48 and 46 to form an electrostatic latent image, which is developed by the developer 28. Thereby, the electrostatic latent image is visualized as a toner image. Next, the charger 29 transfers the image onto a transfer paper 30 . The transfer paper 3o in the cassette 31 is sent into the apparatus by rollers 23, and is sent toward the drum 22 by registration rollers 37 with accurate timing. At this time, the leading edge of the electrostatic latent image and the transfer paper 30 are brought into alignment at the transfer section. Then,
The transferred transfer paper 30 is conveyed by a belt 39, heated and stabilized by a fixing roller 40, and then discharged onto a tray 42.

Note that the above-mentioned operation order designation switch 12b may generally be any operation order designation means.

〔Effect of the invention〕

As described above, since the present invention is provided with the scanning order specifying means, when making a book copy, the book can always be set in a fixed direction regardless of the binding direction.

Furthermore, the scanning order specifying means having a display has the advantage that the operator's effort can be greatly reduced and the copying operation can be carried out efficiently and accurately.
