A cassette case 13 is removably installed on one side of the lower part of the interior of the main body 1, and when the cassette case 13 is inserted, there is a feeder that comes into contact with the top surface of the uppermost sheet of the stack of sheets. A paper roller 14 is provided,
and paper feed roller 14. and the vicinity of the transfer device 9 (72
A paper feed path 15 for conveying the paper in the cassette case 13 to the transfer device 9 is provided between the cassette case 13 and the transfer device 9.

A portion of the guide plate constituting the paper feed path 15 is cut out, and a pair of upper and lower registration rollers 16 are disposed in the cutout portion.

A fixing device 19 is provided on the other side of the lower part of the interior of the main body 1, and a paper conveyance path 20 is provided between the fixing device 19 and a separating device IO provided near the photosensitive drum 5. A paper discharge section 21 is provided on the opposite side of the fixing device from the conveyance path 20, and a paper discharge tray 22 is provided outside of the paper discharge section 21.

A scale Fi 25 is placed on the upper left end of the original glass table 2 of the electrophotographic copying apparatus configured as described above, and a liquid crystal display section is disposed between the scale plate 25 and the original glass table 2. 26 are arranged.

That is, as shown in FIG. 11, this display section 26 is composed of a transmissive liquid crystal located on the upper surface of the original glass table 2, and the lower surface of the scale plate 25 facing this display section 26 is painted white so that a white portion is formed. 76 is formed.

The display unit 26 is connected to a central processing unit (CPU) as shown in FIG. An operation panel 58 of the electrophotographic copying apparatus that causes the display unit 26 to display information is connected.

When obtaining a copied image using the electrophotographic copying apparatus configured as described above, an original is first placed on the upper surface of the original glass stand 2. In this case, the edge of the document is brought into contact with the scale plate 25 to set the document at a proper placement position, and then the document is covered with the platen cover 3 and the operation panel 58 is operated.

This operation panel 58 is as shown in FIG.
When the number of copies is selected using the numeric keypad 70, the selected number is displayed on the set number of copies display LED 69. Also 68
is the auto mode key, and when pressed, the mechanism (APS) detects the original size and automatically determines which size paper to feed, and automatically determines the original density and adjusts the copy density. A mechanism (EE mechanism) for setting is operated, and a cassette selection key 66 and a density setting key 67 are provided for manually performing these settings.

Further, 65 is a variable magnification setting key for changing the size of a copy image relative to the original, 64 is a sorter selection key, and 63
72 is a copy start key, and 71 is a stop clear key.

Furthermore, a plurality of other groups of keys are added to the operation panel 58, and the functions of these keys will be described later.
1 and a print key 62.

Then, by turning on the numeric keypad 70 and auto mode key 68, and then turning on the copy start key 72, the copying operation is started, the photosensitive drum 5 starts rotating, and the charging device 6 is also started, and the photosensitive drum 5 Electrification is applied to the outer peripheral surface of the At the same time, the paper feed roller 14 also starts rotating, and the uppermost paper among the papers in the cassette case 13 is conveyed through the paper feed path 15, and when this paper reaches the registration roller 16, the micro It is detected by a detection member (not shown) such as a switch and stops at that position.

At the same time that the paper reaches the registration rollers 16, the exposure lamp of the exposure device 4 turns on and illuminates the lower surface of the original glass table 2, and the exposure optical system consisting of the exposure device 4 and the lens group 24 starts moving. Then, an electrostatic latent image corresponding to the original image is formed on the circumferential surface of the photosensitive drum 5.

Thereafter, as the photoreceptor drum 5 rotates, the electrostatic latent image is developed by a developing device 8 to become a toner image and positioned opposite to a transfer device 9.

On the other hand, the paper is conveyed through the paper feed path 15 by the activation of the registration rollers 16 to a position facing the transfer device 9, so that the toner image on the outer peripheral surface of the photoreceptor drum 5 is transferred by the transfer device 9. After being transferred onto a sheet of paper and separated by a separating device 10, it is conveyed to a fixing device 19 via a conveying path 20, where it is fixed, and is discharged onto a paper discharge tray 22.

Further, the photoreceptor drum 5 is cleaned by the static eliminator 11 and the cleaning device 12, and one stroke is completed.
And the charging device 6 stops operating.

The above operation is then performed for a set number of sheets.

In an electrophotographic copying apparatus that operates as described above, various types of additional information are written on a copied image in the following manner.

First, when the print key 62 of the operation panel 58 is pressed, the central processing unit (CPU) enters a state in which additional information is written on a normal copy image, that is, a state is displayed on the display section 26.

Further, when the print key 62 is pressed, a reduction mode is entered in order to write additional information on a part of the copied image.

A suitable reduction rate is about 2%, and the magnification is xO,9B. With this magnification, the size of the original document will not change much and there will be enough space to write additional information.

As five examples of this reduction, if 2% reduction is included in the general magnification, ×1.0 becomes xO, 9B, Xo, 81 becomes ×0°7
9 is Xo, 71 is Xo, 69 is Xl, 24 is X 1
．． It becomes 22.

The method of moving the lens group 24 to this reduction ratio is as follows.
A pulse motor is used, and a home position sensor (for example, Xl, O) is provided, and the motor can be controlled by the number of pulses from the sensor.

Then, as described above, the original information and additional information can be copied by automatically reducing the size and by speeding up the feed timing of the registration roller 16 when the print key 62 is pressed to speed up the feeding timing.

After turning on the print key 62 on the operation panel 58, the next step is to input additional information from the keys on the operation panel 58 and display it on the display section 26, or display it using a card on which additional information, which will be described later, is recorded. The display on the section 26 is selected by turning the character entry key 59 ON or OFF.

Therefore, when the character input key 59 is turned on, the character input mode is selected, and since this character input mode is further divided into a katakana mode and an alphabet mode, for example, the katakana mode is selected by the mode switching key 61. In katakana mode, input is performed using the following method.

First, a character is selected using the numeric keypad 70 according to the address in the code table shown in FIG. For example, 4 on the numeric keypad 70.
If you input 2, this 4.2 will display the set number of sheets LED 69.
is displayed, and when you press the set key 60 after this, this 4.
The address corresponding to 2, ie, "S" is input and displayed on the display section 26 (FIG. 9(a)). Similarly, 2,0
And when the set key 60 is turned on, "tsu" is turned on (Fig. 9(b)).
), and when 2, 6 and set key 60 are turned on, "mu" is turned on (Fig. 9 (C1)), and 0.1 and set key 6 are turned on.
When 0 is ON, "power" is input (FIG. 9(d)), and the display section 26 displays "So", "Tsu", "Mu", and "Power".

Furthermore, before the set key 60 is turned on, a cursor 75 is located at the bottom of the display section 26;
A display corresponding to the input is displayed in the upper row where is located. Furthermore, when erasing the upper row of characters where the cursor 75 was located, the stop clear key 71 may be turned on.

The cursor 75 is moved to adjacent display positions one by one when the set key 60 is pressed after specifying the address by inputting two numbers as described above. If you want to create a blank, press any one of the density setting keys 67 to move the cursor 75 in the direction of the arrow shown on the surface of the density setting key 67.

Furthermore, when switching from katakana mode to alphabet mode, turning on the mode switching key 61 changes to alpha bent mode.

As a result, even in the alphabet mode, input is made according to the address of the code table shown in FIG. 1θ, similar to the Katakana mode.

In this case, in Katakana mode and Alphabet mode, the addresses of numbers and various symbols are shared, making it easier to handle them.

After displaying an arbitrary display on the display section 26 through the above operations, if a copying operation is started using the copy start key 72, an electrostatic latent image corresponding to the display section 26 and document information will be displayed on the photoreceptor drum 5 during exposure. After that, it becomes a toner image in the developing device 8, and when it passes through the transfer and separation area, the original information and the contents of the display section 26, that is, additional information are recorded.

In this case, the display section 26 is composed of a transmissive liquid crystal, and the scale plate 2 facing the upper surface thereof is
Since a white portion 76 is formed on the lower surface of the scale plate 5, the light from the exposure lamp of the exposure device 4 is transmitted through areas other than the display contents of the display portion 26, and is reflected by hitting the white portion 76 of the scale plate 25. . This white color is the same as the background color of the original information placed on the original glass table 2, so the area other than the displayed content on the display section 26 is white, that is, the same as the background color of the original information, and thus the background color of the display section 26 is white. Image fogging of the copied image due to color does not occur. Furthermore, the distance from the exposure device 4 is based on the display content on the display unit 26;
Since the information matches the original information on the original glass table 2, a clear copy image can be obtained.

The position of the additional information in this copied image is determined by the scale plate 25.
If the position is as shown in Fig. 12 (a), the first
3 (a), in the case of (b) of Fig. 12, it is shown in Fig. 13 (b), and in the case of (C) of Fig. 12, it is shown in Fig. 13 (C).
) is recorded as follows.

In this case, if the leading edge of the document is brought into contact with the scale plate 25, it will appear at position 1, and if the trailing end is brought into contact with it, it will appear at position 2. If the additional information is the distribution destination, the position ■ in Figure 13 (C1 position I is the publisher and date is Figure 13 + a), and if it is the page, the position is in Figure 13 (b). The position ■ is suitable for each position, and the display unit 26 is moved to the position (bl) shown in FIG.
It can be applied to all document sizes if the position is as follows.

Next, when displaying on the display section 26 using the card storing the additional information, first the character entry key 59 is turned off. As a result, only the print key 62 is turned on, and preparation for reading the card is completed.

Then, by simply placing a plurality of cards on a tray in the card reading device 30 shown in FIGS. 3 to 6, the stored contents of the cards are displayed on the display section 26. That is, when a plurality of cards 54 are placed on the tray 39 and the door 49 is closed, both trays 39 and 40 are raised by drive members (not shown), and one tray 39 has a stack of cards 54 on the upper surface of the conveyor belt 34. When it comes into contact with the lower surface, a sensing member (not shown) stops the driving member at that position. Further, the other tray 40 stops at a distance of one card from the conveyor belt 34.

Next, when the copy start key 72 is pressed, the movable stopper 35 is lowered and at the same time the conveyor belt 34 is activated to convey the card on the tray 39. Further, since the movable stopper 36 is in a protruding position, the conveyed card comes into contact with the movable stopper 36, and when the card reaches the upper part of the reading member 41 is detected by the detection member 42, the conveyor belt 36
4 stops, and the movable stopper 35 rises to prevent the next card from being conveyed. The memory contents of the card are read by the central processing unit (C) by the reading member 41.
PU), the contents are displayed on the display section 26 via the driver. As a result, the contents of the display section are copied together with the original image.

When processing of the first card is completed, the movable stopper 36 is lowered, the conveyor belt 34 is moved to the top of the tray 40, the tray 39 is raised by the thickness of one card, and the tray 40 is The next card is moved down by one thickness and is moved by the conveyor belt 34 and positioned above the reading member 41 in the same manner as before. and conveyor belt 3
When the tray 39 finishes feeding the last card, the tray 39 descends to the initial state, and when the ejection of the last card is completed, the tray 40 also descends to the initial state.

In addition, when using only one card, if the card is inserted into the insertion slot 55 of the door 49 of the reading device 30, the card will be located on the top surface of the reading member 41, and the detection member 43 will be located on the back side in the insertion direction. After the card is read, the conveyor belt 34 transfers the card to the tray 40 by a driving member.
It is placed at the top.

Therefore, even if a card is used, the display section 2
6 is configured to be able to display the contents stored on the card.

Note that the central processing unit <c P U) has a buffer RA.
Since M is connected, the contents of the display section 26 can also be registered on the card via the card reading device 30 (also used as a writing device).

Further, in the above embodiment, the lower surface of the scale plate facing the display section was painted white to form a white part, but the white part is not limited to this, and a white tape may be attached. Furthermore, even if it is not white, if it is given a color that matches the sensitivity characteristics of the photoreceptor drum, for example yellow, the background color of the transmissive liquid crystal will have the same characteristics as white, thereby preventing image capri. It is something that can be done.

〔Effect of the invention〕

By configuring the present invention as described above, even when the additional information is copied together with the original information, image fogging does not occur in the image portion corresponding to the additional information, and the distance from the exposure device is smaller than the original information. Since the image and the displayed content match, the focus of both can be matched.
These have excellent effects such as being able to obtain high quality copied images. .
