At the time o an access key is operated after inputting numerical values 0-9, the contents indicatd by the buffer K out of memory R storing a display pattern and constituted in a ROM are read out and written in a display momory, so that a display pattern using the registered value as a code is displayed on the dot matrix type liquid crystal display device 2. Thus, a required display pattern can be accessed and displayed.

Description

[Detailed Description of the Invention] Technical Field> The present invention relates to a copying machine that imprints the display content of a display device onto a copied image by scanning the document together with a display device provided on the document table when scanning the document. .

<Summary of the Invention> The copying machine according to the present invention has a dot matrix display device disposed on a part or the entire surface of the document table,
This display device can display any pattern,
This is a copying machine that allows any pattern to be projected onto a copied image.

<Prior art and its drawbacks> Conventional general copiers scan a document placed on a document table and form the document image on a photoreceptor. There have also been proposals that imprint the date, etc.

Such conventional copying machines can only imprint limited information on copied images, and cannot be used universally for various copying tasks. It's about doing.

<Structure and Effects of the Invention> The present invention includes a dot matrix type display device disposed on a part or the entire surface of a manuscript table, a memory for storing patterns to be displayed on the display device, and a memory for storing patterns to be displayed on the display device, and data read from the memory. a driving circuit for driving each dot of the display device based on the pattern, a pattern setting means for setting a pattern to be stored in the memory, and a display position movement instruction means for moving the display position of the set pattern. It is characterized by

With the above configuration, an arbitrary pattern can be set in the memory by the pattern setting means, and thereby the drive circuit drives each dot of the display device consisting of a dot matrix type display device. Further, the display position of the set pattern can be moved by the display position movement instructing means, and any pattern can be displayed at any position on the display device provided on a part or the entire surface of the document table. The pattern thus displayed can be scanned together with the original and imprinted on a copy image.

According to this invention, for example, by copying a mark at the center of the left end of a copied sheet, it is possible to indicate the center position at the time of punching (stapling holes). Furthermore, by imprinting a symbol representing the type of copy image according to the content of the copy image, sorting can be useful for searching when working or filing.

<Embodiment> FIG. 1 is a diagram showing the document table and its surrounding area of a copying machine according to an embodiment of the present invention, and corresponds to the top surface of the copying machine when the document cover is released.

The document table l is made of a glass plate, and a dot matrix type liquid crystal display device 2 is integrally incorporated in its left end (shaded area). The document is placed on the left side of the document table 1 along the right end (P in the figure) of the guide plate 3 which indicates the document placement reference position, and at the center of the document table in the front-rear direction. Note that a plurality of frames shown on the document table in the figure represent positions where standard size sheets are placed.

A dot matrix type liquid crystal display device is a display body consisting of a large number of dot segments, and can display any pattern represented by these dots. For example, the second
As shown in the figure, characters can be displayed in the center of the display device. However, until the print key is operated, this display appears in a normal pattern when viewed from above the document table, but when the print key is operated, the display pattern changes to a mirror image as shown in Figure 3. is displayed. This is because the document scanning means provided at the bottom of the document table scans along the back surface of the document table, and the display pattern in the normal orientation is imprinted on the copied image.

FIG. 4 shows a block diagram of the control section of the copying machine. Overall control is performed by program processing of CPU10.

The control program is written in the ROMII in advance. In addition, a predetermined fixed display pattern is written in this ROM, and is read out as necessary.
displayed on the display device. The RAM 12 is used as a working area for flags, buffers, etc. when executing the control program, and also stores arbitrary patterns set by the operation of the key manual device 16 together with pattern codes. This memory is backed up by a battery and remembers the set pattern even if the main power is turned off. LCD controller 13 is display memory 1
4 are sequentially read out in accordance with the display timing to generate segment signals for the dot matrix type liquid crystal display device 2. It also outputs a common signal to the display device 2. The display memory 14 is a memory that stores a pattern to be displayed on the display device 2 as a bit pattern, and the display pattern to be displayed is determined by bit setting or bit reset. The key controller 15 generates a strobe signal to the key operator 16, and determines the operated key by reading the return signal. By accessing this key controller 15, the CPU 10 can read the operated keys. The display 18 is a display that displays guidance in response to the operation of each key, and is driven by the driver 17.

FIG. 5 and FIGS. 6(A) to 6(H) are flowcharts showing the processing procedure of the control section. When the power is turned on, the keys are first read as shown in FIG. If there is any key input, the process moves to the process corresponding to the input key according to the state of the flag FM. Here, the flag FM is a flag representing the pattern copying motor, and in this mode, some keys act as keys for the pattern copying mode. Some of the plurality of keys of the key-powered device are used both as various designation keys for pattern copying and as designation keys for normal copying, and can be used properly depending on the mode.

When the mode key is operated, the state of the flag FM is inverted as shown in FIG. 6(A). This allows mode switching. When the numeric keypad is operated, a number is placed in the buffer K as shown in FIG. 6 (CB).

After inputting a number from 0 to 9, if the call key is operated, the contents shown in the buffer are read out from the memory R that stores display patterns configured in the ROM, as shown in (G) of the same figure. , write to display memory. As a result, a display pattern having the entered value as a code is displayed on the dot matrix type liquid crystal display device 2. After numerically inputting the pattern to be displayed using the ten keys, a desired display pattern from among the display patterns already stored can be recalled and displayed by operating the recall key.

To move the pattern displayed in this way in the vertical direction, operate the up arrow key or the down arrow key.

As shown in Figure (H), when the up arrow key is operated, the entire display pattern can be scrolled upward by moving the contents of the display memory upward bit by bit. . Conversely, when the down arrow key is operated, the display pattern can be scrolled downward by shifting the contents of the display memory downward bit by bit. In this way, the display position of the display pattern can be moved to an arbitrary position.

Thereafter, when the original is set on the original table and the print key is operated, the contents of the display memory are first swapped so that they become a mirror image, as shown in FIG.

Thereafter, after the copying process is performed by operating the document manipulation means, the normal pattern is displayed by swapping the contents of the display memory again.

Although the above example was an example in which a fixed display pattern written in advance in the ROM was called up and used, it is also possible to set an arbitrary display pattern and use this. First, the position of the dot to be displayed is designated as X and Y coordinates. In other words, for example, set the position of the X axis using the numeric keypad, and
By operating the axis specification key, copy the contents of the buffer to X as shown in the same figure (C), and after operating the numeric keypad to set the Y-axis position, operate the Y-axis specification key. Set its value to Y by By specifying the X and Y coordinates in this manner, the corresponding segment is displayed blinking. If you want to erase a dot that is already displayed, do the same as in the previous case, and move the specified position to X, Y.
After specifying the coordinates, by operating the set/reset key, the corresponding bits are inverted as shown in FIG. This allows the corresponding dot to be erased.

After repeating the above operations to create an arbitrary display pattern, enter a number of 10 or more as a code representing that pattern from the numeric keypad, and then press the registration key to
As shown in F), the bit pattern set in the display memory is stored in the area shown in the buffer of the memory M configured in the RAM. Here, if the registration key is operated after inputting the codes θ to 9, a message indicating that registration is not possible will be displayed. This is because the codes O to 9 represent fixed display patterns.

When calling any display pattern registered in this way, in the same way as when calling a fixed display pattern,
This is done by inputting the code from the numeric keypad and then operating the call key. That is, as shown in FIG. 3G, the contents corresponding to the values shown in the buffer K of the memory M are read out and written into the display memory.

Using the functions described above, characters such as those shown in FIGS. 2 and 3 can be displayed and imprinted on a copy image. It is also possible to display figures such as those shown in FIGS. 7 and 8 as patterns to be displayed. The examples shown in FIGS. 7 and 8 are copying machines in which the original is placed on one side of the original table, and the figure 2a is the center mark used when punching the copied paper. Such a figure is used by positioning it in the vertical center depending on the size of the document to be copied. In this case, it is also possible to prevent unnecessary movement instructions by limiting the vertical movement range to within the range of the document to be copied. Further, in the embodiment, the display pattern becomes a mirror image when the print key is operated, but the display may be changed when the document cover is closed.
