Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applied to a copying machine, for example, and in particular, when copying, the copy information such as the number of copies, paper size, copy density, etc. is not input using operation keys, but the copy information is automatically input. The present invention relates to a device for setting a copying machine to a copying machine.

When making copies, the information given to the copier itself includes the number of copies, paper size, copy density,
There is also copy information that provides various conditions for copying, such as whether or not copying is to be repeated. Conventionally, when making a copy, the copying operation was performed by inputting the above-mentioned copy information and then pressing a copy button. When the copying is finished and the same type of document, that is, the next document is to be copied again, it is necessary to read out the number of copies previously input using a repeat key or the like, and to make a copy. In this case, it is assumed that the paper size, copy density, etc. are maintained as they are.

However, when copying a document different from the above-mentioned type of document, it is necessary to provide the copying machine with copy information for copying again, which is very troublesome and makes the copying operation complicated.

In view of the above points, the present invention provides copy information for a copying machine that stores copy information necessary for copying in advance in a non-volatile memory, reads out the stored contents, and controls a copy operation according to the contents. It is a setting device.

In other words, in the field of administrative processing, meeting notices,
In many cases, the number of copies and formats of documents to be distributed, such as minutes, distribution of slips, design reports, technical correspondence, etc., are fixed. Therefore, the present invention classifies each document as described above by item, stores information such as the number of copies, paper size, copy density, and whether repeat copying is necessary for each item, and specifies the item. The user simply sends sheets of desired size and makes the necessary number of copies with a copy density that corresponds to the document for that item. Furthermore, if there are a large number of originals, the information for repeated copying has been input, so that the replaced originals are copied in the same manner as described above.

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a copy information setting device according to the present invention. In the figure, 1 is a key input device provided on the operation panel of the main body of the copying machine. The M□ key of this key input device 1 is a non-volatile memory 22 (hereinafter referred to as memory) which will be described later.
The input enable key is used to set the mode that allows information input to store copy information for each item (various originals), and the R□ key is the memory 2 key.
2 is a read key for setting the mode for reading out the stored copy information, the E□ key is a key for storing input copy information in the memory 22, and 2 is an item input key for specifying an item. ,
3 is a size input key for setting the copy paper size, 4 is a copy density selection key for selecting copy density, and 5 is a setting key for setting whether or not to repeat copying, and the RE key is for repeat copying. The repeat key, the N□ key is a non-repeat key that does not repeat copying, the 6 key is a number key for setting the number of copies, and the C□ key resets registers 16, 17, 18 and flip-flops 7 and 8, which will be described later. The clear key and CE key are entry keys that reset only the register 16. The embodiment of the present invention shows an example in which five items (C ₀ C ₁ C ₂ C ₃ C ₄ ) of predetermined copy information of documents etc. can be stored. This is just an example and can be increased as needed.

The key input of the M□ key is applied to the set terminal of the flip-flop 7 which maintains the input enable mode state, and the key input of the R□ key is applied to the set terminal of the flip-flop 7 which maintains the input enable mode state.
The input of the E□ key is applied to the one-shot multi 9. Also,
Inputs from the input keys 2 to 6, that is, input means, are applied to an input control circuit 15 via encoders 10 to 14, respectively. The flip-flop 7, ie, the first state storage unit that maintains an input-enabled state, applies its set output to each of the encoders 10-14, thereby making the encoders 10-14 operational. Flip-flop 8 applies its output only to encoder 10;
Enable 0. Also one shot multi 9
applies its output to the input control circuit 15.
The input control circuit 15 receives input from the encoders 10 to 10.
14 is temporarily latched, and the latched signal is parallel-to-serial converted using the output signal from the one-shot multi 9 and transferred to the register 16 at the next stage.

The register 16 stores the item information from item key 2 in the _a0 area, the number of copies in _a1 , the copy paper size information in _a2 , the copy density information in _a3 , and repeats copying in _a4 . It remembers information about whether or not it is true. Register 16 transfers information via gate G ₁ or G ₂ to register 17 or 18 of the same capacity. The gate _G1 is a gate that opens when a pulse is generated from the pulse generator 19 which outputs the signal from the one-shot multi 9 with a delayed output. Gate _G2 is a gate that opens when a pulse is generated from a pulse generator 21 that delays an output pulse from a comparison circuit 20, which will be described later.

The register 17 is a register used for reading from and writing to the memory 22. The information in this register 17 is transferred via gate _G3 .
In order to always retain the written information, the memory 22 is connected to a backup power supply 23 that supplies power even when the copying machine is powered off. This is so-called non-volatile memory. The memory 22 is also provided with an address decoder 25 that decodes and outputs the count contents of the address counter 24 and specifies an address. The memory 22 is
The storage information designated by the address decoder 25 is sent to the register ₁₇ via the gate G4. Gate _G4 is a gate that opens upon receiving an output pulse from a three-input AND gate 26, which will be described later. Further, the address counter 24 is provided with an adder 27,
Count up the count contents. Here, the count 24 is a quinary counter, and after counting the count content "5", the adder 27 counts "1". Moreover, the counting operation starts when the gate _G5 is opened by the output from the AND gate 26.

On the other hand, each area _a0 of the registers 16 and 17 is connected to each input side of the comparator circuit 20, so that coincidence detection is performed. The coincidence output of the comparator circuit 20 is applied to one input terminal of an AND gate 26 via an inverter _In1 . Further, the area _a0 of the register 17 is sent to the zero detection circuit 28, where zero detection is performed. The zero detection circuit 28 applies its output to the input terminal of the AND gate ₂₆ via the inverter In2. The coincidence output of the comparator circuit 20 is applied to the pulse generator 30 via the OR gate 29, causing gate _G6 to open. The contents of register 17 are transferred to register 16 by opening this gate _G6 .

The area _a1 of the register 16 is sent to the zero detection circuit 31, where zero detection of the number of copies is performed. The detection output of this zero detection circuit 31 is applied to the other input terminal of the OR gate 29. Further, a subtracter 32 is connected to the area _a1 of the register 16, and the subtracter 32 opens the gate _G7 to subtract the number of copies. That is, the gate _G7 is opened every time a copy count signal C is outputted every time one sheet of copying is completed in a copying operation.

As will be explained later, the set output m or r of the flip-flop 7 or 8 is connected to the OR gate 33 at the other input terminal of the AND gate 26.
It has been added via. The comparator circuit 20 is enabled to operate when the signal r is applied thereto, and the zero detection circuits 28 and 31 start their operations when the signal m and the signal RE from the repeat key are input.

The copy count signal C is also applied to a delay pulse generator 21, which sends a delay pulse to the gate _G2 . Furthermore, the delay pulse generator 19 becomes operable by inputting the signal m, and sends the delay pulse to the gate _G1 when the E□ key is pressed.

Furthermore, the information in the register 16 is transmitted to the display drive circuit 34.
and is displayed on the display device 35 via this drive circuit 34.

Also, the set output terminal of the flip-flop 7 is
It is connected via an inverter In ₃ to a light emitting diode LM, ie an input-enabled display. The set output terminal of the flip-flop 8 is connected to a light emitting diode LR, ie, a readable display section, via an inverter _In4 . Therefore, light emitting diode
If the LM is emitting light, it informs that copy information can be input, and if the light emitting diode LR is emitting light, it is informing that the copy information stored in the memory 22 can be read. In other words, by the display of the light emitting diode LM, it can be recognized that copy information can be input, and by operating the key E for storing copy information using the key input means 2 to 6 of the key input device 1, the display can be changed. The light turns off and you know that the input information has been stored. Also, in reading, it is possible to read the stored copy information and perform copy control according to the read copy information by lighting the light emitting diode LR. It can be seen that reading can be performed by operating the desired item key 2, key E□, etc.

In the circuit configuration as described above, the operation when copying information is input and stored (registered) for each item will be explained first.

For example, assume that the necessary information for copying a slip is that the number of copies is "5", the copy density is "light" for copying slips, the paper size is "B ₅ ", and further copies are to be made repeatedly.

Therefore, when the M□ key is pressed, the flip-flop 7 is set and outputs the signal m. This signal m
The output enables each encoder 10 to 14 to operate. Furthermore, when the flip-flop 7 is in the set state, the light emitting diode LM emits light to notify that copy information can be input. Therefore, it can be confirmed that copy information can be input for each document, and that copy information can be input using the key input means 2 to 6. At this time, the flip-flop 8, which is set when maintaining the readable state, has been reset, and the light emitting diode LR is naturally turned off. The next operation is to copy the document, for example with the item key.
If the C ₀ key is selected, the encode signal is latched into the input control circuit 15 when the C ₀ key is pressed. Also size key 3 B ₅
key, copy density key DN ₀ key, copy repeat key 5 RE key, and numerical key 6 to input the number of copies "5", each copy information is
It is latched to the input control circuit 15. After inputting the information necessary for copying as described above, press the E□ key, that is, the memory key, and the input control circuit 1
The copy input information latched in the register 16 is transferred to each area a ₀ , a ₁ . . . a ₄ of the register 16, respectively.

On the other hand, when the M□ key is pressed, a signal m is output, so that a signal is output from the AND gate 26 via the OR gate 33. This signal P opens gates _G4 and _G5 . Therefore, the address counter 24 counts and the address decoder 25
Addressing of the memory 22 takes place via. Information stored in the memory 22 in the area specified by the address decoder 25 is sent to the register 17 via the gate _G4 . The information sent to the register 17 is subjected to zero detection in the zero detection circuit 28 in its area a ₀ . In other words, this is an operation for searching for free space in the memory 22. For example, if information is stored in the area of the memory 22 at the address, the zero detection circuit 28 will not output a detection signal. Therefore, a signal is output from the AND gate 26, and the count-up operation of the address counter 24 is executed. Also, if no information is stored in the addressed area of the memory 22, it is transferred to the register 17.
A detection signal is output from the zero detection circuit 28, and the AND gate 26 is closed. In other words, the address counter 24 continues to hold the count that specifies the free area of the memory 22.

The above operation operates simultaneously with the pressing of the M□ key, and is completed before the copy information is input by key, that is, before the E key is pressed. Register 16 by pressing the E□ key.
The copy input information transferred to is transferred from the delay pulse generation circuit 19 to the register 17 a certain period of time after the E□ key is pressed. Further, the copy input information transferred to the register 17 is sent via the gate _G3 to the memory 22 currently designated by the address counter 24, ie, an empty area of the storage means, and is stored therein.

In the manner described above, copy information such as the number of copies of a document, which is predetermined for each of a plurality of manuscripts, is registered in the memory 22 in correspondence with each item. Here, if the copy information is input by mistake, the user presses the CE key to reset only the contents of the register 16, and operates keys 2 to 6 again to input the copy information. If you enter the copy information incorrectly,
This can be determined by looking at the display on the display device 35. Note that the signal n(E□
The flip-flop 7 that stores the state of the input-enabled mode is reset by the signal output from the delay pulse generation circuit 19 when the key is operated, and the input-enabled mode is automatically canceled. goes out. Therefore, it is possible to know that the input copy information has been stored in the memory 22 by turning off the diode LM by operating the E□ key.

Next, by reading copy information, copy control according to the read information will be explained. That is, the user presses the R□ key, that is, the readable key for reading out the information stored in the memory 22. This key signal sets flip-flop 8, the second state memory. Therefore, the light emitting diode LR (readable display section) indicating the pressed state of the key lights up, allowing the user to recognize that the stored copy information can be read. Therefore, it is understood that key input for reading copy information can be performed using key 2 for reading copy information and key E□. At this time, only the encoder 10 is enabled, and when a desired item is pressed with the item key 2, the information is latched into the input control circuit 15.

On the other hand, when the signal r is generated by pressing the R□ key, the address counter 24 receives count signals sequentially and changes the address designation of the memory 22.
Then, the information of the designated area is sequentially sent from the memory 22 to the register 17. That is, the R□ key, item key 2, and E□ key constitute reading means. Therefore, if the E□ key is pressed after specifying an item, the specified item information latched in the input control circuit 15 is transferred to the area _a0 of the register 16. Therefore, the comparator circuit 20
Compare at a ₀ . When this comparison circuit 20 detects a match, the AND gate 26 closes and the address counter 24 stops counting.
The contents stored in the memory 22 designated by the address counter 24 are transferred to the register 17 . This means that the copy information stored in the memory 22 corresponding to the input designated item has been read out. The output of the comparison circuit 20 for detecting coincidence is sent to the pulse generator 3 via the OR gate 29.
0 and open gate _G6 . Therefore, the copy information in register 17 is transferred to register 16. In addition, the copy information transferred to the register 16 is transferred to the register 1 by sending a delay pulse from the delay pulse generator 21 to the gate G ₂ in response to the coincidence output.
8, that is, it is also sent to the copy information temporary storage unit. Note that the copy information in the register 16 is displayed on the display device 35 via the drive circuit 34.

Next, processing of the copy information sent to the register 18 will be explained. The area _a1 of the register 18 is sent to the copy number determination circuit 63, where the number of copies is determined. In other words, when the number of copies is multi-copy, the determination circuit 36 outputs a signal MC for causing the main body of the copying machine to perform multi-copy.

Area _a2 of register 18 is sent to decoder 37, and paper size selection signals _B4 , _A4 ,
Output as _B5 . For example, as shown in FIG. 2, the size selection signal obtained by the decoder 37 is
AND gates G ₁₀ to G ₁₅ which input the discrimination signals sent from the upper and lower cassette discrimination circuits 40 and 41
is added to the other input end. The gate outputs of AND gates G ₁₀ to _{G 12} and gate outputs of G ₁₃ to _{G 15} corresponding to the upper and lower stages are connected to OR gates O ₁ and
It is sent to the paper feed roller selection circuit 42 via _O2 .
The selection circuit 42 receives input from the OR gates O ₁ and O ₂ and selectively drives paper feed rollers 45 and 46 located corresponding to the cassettes 43 and 44 inserted into the cassette insertion portion of the main body of the copying machine. . For example, if the cassette inserted in the upper stage is _B5 , a discrimination signal is applied to gate _G12 via cassette discrimination circuit 40. Also, area a ₂ of register 18
If the content is paper size B ₅ , the decoder 37
Send the signal of B ₅ to gate G ₁₂ via. This opens the gate _G12 , and the signal is supplied to the selection circuit 42 via the OR gate _O1 , so that the paper feed roller 45 is selected to be driven.

Here, if a cassette corresponding to the size signal outputted from the decoder 37 is not inserted into the upper or lower insertion section, a light emitting diode 47 is provided to notify this. That is, orgate O ₁ ,
The signal from O ₂ is applied via OR gate O ₃ to the other input terminal of gate G ₁₆ to which the signal r of the set output of flip-flop 8 is input.
A light emitting diode 47 is connected to the output end of _G16 . Therefore, if a cassette corresponding to the size signal from the decoder 37 is not inserted, the OR gate will not be activated.
No signal is output from O ₁ and O ₂ , and the AND gate G ₁₆
remains closed, and the light emitting diode 47 emits light due to the supply of power V to notify that the desired cassette is not inserted.

Further, the area a ₃ of the register 18 receives signals GN ₀ , GN 1 , and GN ₁ which are sent to the decoder 38 and control the copy density.
Output as GN ₂ . This copy density signal is
In this embodiment, it is used as a signal for changing the bias voltage in the developing section. FIG. 3 is a circuit diagram showing an example thereof. In the figure, a bias voltage is supplied to a developing roller 49 that develops an electrostatic latent image formed on a photosensitive drum 48 into a toner image, thereby changing the copy density. For example, the copy density is reduced by increasing the bias voltage.

As for the above bias voltage, the power supply V ₀ is connected to the resistor R ₀
It is applied to the developing roller 49 via. In that case, a resistor Ra and a transistor Tr ₁ are each connected in parallel to the resistor R ₀ ,
A series circuit of resistor Rb and transistor Tr ₂ and resistor Rc and transistor Tr ₃ are connected. Then, each copy density signal DN ₀ to _{DN 2} is applied to each base terminal of the transistors Tr ₁ to _{Tr 3} . Therefore, the developing roller 49 is supplied with a bias voltage obtained by dividing V ₀ by the resistor R ₀ and any one of the resistors Ra to Rc, so if the signal DN ₀ "lightens" the density, the bias voltage is To increase the resistance Ra,
Rb and Rc are selected according to the relationship Ra>Rb>Rc.

Further, the area _a4 of the register 18 is sent to the decoder 39, and a signal RE for repeat copying and a signal N for otherwise are generated.

Therefore, as mentioned above, by operating the R□ key, the read state is set, and in this state, the desired item is selected with the item key 2, and the E□ key is further pressed.
Copy information according to the desired item selected by the item key 2 is read from the memory 22, and this copy information is displayed on the display device 35. The user only has to set the document while looking at the display on the display device 35 and press the copy button to start the copying operation. In other words, paper of a size corresponding to the set original is fed into the copying machine, an image is formed on the fed paper at the optimum copy density, and a predetermined number of copies are made without any operation of the copying machine. The copy operation can be controlled without operating the copy section. At this time, each time the copy count signal C is output, the number of copies is subtracted from the area _a2 of the register 16 that stores the information on the number of copies by the action of the subtracter 32, and the number of copies is subtracted on the display device 35. The remaining number will be displayed. Furthermore, in the case of repeated copying, since the signal RE from the decoder 39 is output, the zero detection circuit 31
detects that the number of copies in area _a2 of register 16 becomes "0". Therefore, when a detection signal is output from the zero detection circuit 31, the pulse generator 30 is activated via the OR gate 29, the gate _G6 is opened, and the information in the register 17 is transferred to the register 16 again. Therefore, after copying the first original, set the next original and press the copy button.
The operations described above are repeated.

In this embodiment, writing as the memory 22,
Although a readable memory (RAM) is used and a backup power supply 23 is provided to make it non-volatile, the present invention is not limited to this, and a magnetic storage medium such as a magnetic tape may be used as the storage means.

As described above, according to the present invention, various conditions for copying are stored in advance in accordance with each of a plurality of originals, and the stored copy information is read out, and the read copy information Since copy control is performed according to the copy information, when copying is always performed using fixed copy information, the input operation for copy information, which becomes complicated each time, can be omitted, and the input operation for copying can be simplified.

In addition, by key operation to enable input of copy information, the display shows the state in which this input is possible.
LM is used to display the information, and the display unit LR indicates the state in which the data can be read by key operation.
This display allows you to easily recognize whether copy information can be input or read.
It is possible to prevent mistakes in inputting copy information and reading mistakes, and to ensure reliable key operations. Furthermore, by automatically disabling the copy information input enable state and turning off the display after the input of copy information is completed, you can know that the input copy information has been memorized, and the input copy information will be memorized. If you can remember the information again later, you will no longer have to make mistakes.
