Description

[Detailed description of the invention] (Technical field) The present invention relates to an input device for a copying machine.

(Prior art) A so-called editing copying machine that specifies (trimmes) a necessary part of a document and copies it, combines the specified parts to make a single copy, changes the size, and copies in a specified color. have recently appeared on the market in large numbers.

By the way, in the conventional edit mode and edit address input device, input is made from an editor board such as an edit key, a numeric keypad, or a pressure-sensitive type.

With a numeric keypad, etc., the editing address must be measured once with a ruler, which is time-consuming.

Additionally, editor boards were expensive and unsuitable for popular copying machines.

(Purpose) The present invention solves the drawbacks of the conventional example, and allows easy editing by using an editing sheet on which barcodes corresponding to the editing mode and addresses in the X and Y directions are printed. The object of this invention is to provide a copying machine in which an address can be input.

(Configuration) For this purpose, the copying machine according to the present invention includes an editing sheet on which barcodes corresponding to addresses in the X direction and Y direction are printed;
The present invention includes a barcode reader for reading the barcode on the TI collection receipt, and a control section that sets an edit address in the edit mode based on the output from the barcode reader.

First, an overview of the present invention will be described.

FIG. 13C is a diagram showing an editing state in combination and movement modes.

The copying machine main body 200 has the same functions as a conventional copying machine, but has a receiving section 39 for receiving signals from the barcode reader 100 and an operation section 202 that can display edited data.

The barcode reader 100 has a shape (for example, a pen shape) that is easy to handle by hand, and has a reading section 5, a power switch 3, a transmission SW 6 for transmitting read data to the main body of the copying machine, and a transmission section 7.

The editing sheet 17 is made up of a mount 17b and a transparent sheet 17a that are glued together on one side and can be fixed by sandwiching the original 203 therebetween. Also, a barcode is written on its surface.

There are two types of barcodes: a code for entering dimensions (X mm from the left edge of the document: Y mm from the top edge of the document) and a code for inputting the mode (trimming, masking, red, green, etc.). has been done.

The operator sets the original as shown in Fig. 5, traces the barcode on the editing sheet 17 with the reader 102 as shown in Fig. 6, inputs the desired data, and then sends a signal to the copying machine shown in Fig. 1. When the input data is sent, the input data is displayed on the main body operation section 33 as shown in FIG.

After confirming the data on the display, the operator places the original in the copying machine and presses the start button to make a copy with only a portion of the original masked, variable magnification, and multicolor printing as shown in Figure 7. You can edit and copy in your favorite mode, such as , move, etc.

FIG. 8 is a table of codes related to the editing mode, which is a special mode possessed by the copying machine of the present invention. For example, #60" is assigned to trimming, "62#" is assigned to scaling, and #65# is assigned to red.

FIG. 9 shows the structure of a bar code indicating an address, which is composed of a one-digit mode section indicating the address mode and a two-digit data section indicating the address (in cm).

If the length of Ni bar #O# is 0.33, the total is 13.
．． 2 ms.

Figure 10 shows the code indicating the address, and the first digit corresponding to the mode section is "7#" indicating the X direction, "18" indicating the Y direction, and the following two digits are the actual distance from the origin. is shown in cm. That is, "732" indicates a position of 32 m in the X direction.

FIG. 11 shows details of a portion of FIG. 4, the address barcode section.

A 1cIII square is printed on the editing sheet 17, and the position of the square from the X direction and the Y direction is indicated by a bar code, alternating vertically.

By printing the barcodes alternately at the top and bottom, sufficient space is secured before and after the start and stop codes.

As shown in Figure 12, the variable magnification mode means inputting an arbitrary point (x+-x,') on the document using a barcode, and inputting the desired size x+-XI) using the barcode. This mode allows copying.

Furthermore, as shown in Figure 13, compositing and moving mean inputting an arbitrary point (x3-x4) in the first original pot with a barcode, and inputting the starting point X of the moving compositing of the second original using the barcode. This mode allows moving composite copying by inputting.

The above is an outline of the system of the present invention, but according to the present invention,
This will be explained in detail below.

FIG. 14 is an example of a system conceptual diagram. First, this example will be explained.

The barcode reader 100 includes a reading unit that reads barcodes on a medium, a decoding unit that decodes the output signal from the reading unit into character data, a memory unit that stores the decoded character data in the order in which it is read, and a memory unit that stores the decoded character data in the order in which it is read. Main body control section 10 consisting of a transmitting section that transmits character data within the section to the main body control section.
1 is comprised of a normal control section and a receiving section that receives signals transmitted from the barcode reader 100.

Figure 15 shows the 2 barcode systems currently used.
It shows the correspondence between the characters and codes of 0 UT”/OR3, and has the following requirements.

(]) One character of a numeric barcode consists of 3 thin bars and 2 large bars for a total of 5 pieces.

(There are dedicated codes for 21S T A RT and 5TOP,
It consists of one thin bar and two large bars.

(3) S T A, 1? A blank space of a certain value or more is required as a prefix space before and after the T and 5TOP codes.

(4) A character gap with the same size or more as the thin bar is required between characters.

(5) There is a method in which the space between the black bars is used as a mere space (the space has no meaning), and a method in which this space is also used as a narrower size of the white bar (the space has meaning). .

(6) The number of digits is variable.

Other barcode systems include +1) NW-7 f21cODE39° (3) Common product code (JIS B9550), but in the present invention, the 2OUT/OR3 (space part has meaning) code is basically used. do.

FIG. 16 is an example of 20UT/0F5 (space part is meaningless).

FIG. 17 is an example of 2OUT/OR3 (space part has meaning).

Figure 18 (1), ! 21. (3), (41 shows the concept of how the 20UT/OR3 (space part is significant) barcode printed on the media is read and processed by the barcode reader 100 shown in Fig. 14. First, the printed barcode is read by the reading section as a high level signal for the black part and a low level signal for the white part, and is sent to the decoding section.The barcode reader 100 is a handheld scanning type. Therefore, the high/low time width of the reading unit's power changes depending on the scan speed.The decoding unit corrects the scan speed of the above output signal and converts it into a large bar (#1").
, a thin bar ('O') is determined and further decoded into character data. The decoded data is stored in memory. Finally, the data in the memory is transmitted to the main body side control unit 101 in an asynchronous mode having a start bit and a stop bit in response to a signal from the transfer SW. The figure shows that data 45H (OlooOIOIB) is sent from the least significant bit.

FIG. 19 shows a specific circuit configuration of the barcode reader 100. Except for the reading section 5, a decoding section, a memory section, and a transmitting section are constituted by a one-chip microcomputer.

1 is a 1-chip microcomputer, and a ROM 11 contains a control program including decoding processing, fixed data, etc.
RAM that stores read data, decode data, etc.
12. It has a timer/counter 54 which is used to detect the pulse width of the signal from the reading/retrieval section and serves as 4CLK or one half of a timer. 2 is a crystal, and a system CLK is oscillated by a circuit (not shown) inside the 1-chip microcomputer, and is used as the base CLK of the timer/counter part 54 as well as the basis of the internal timing of the CPU.

Since this barcode reader 100 is independent from the main body of the copying machine, it is driven by a battery 4, and 3 is its power source SW. 6 is a transmission SW for transmitting the decoded data stored in the memory (RAM) 12 to the main body;
13 is its pull-up resistor. Reference numeral 7 denotes an LED that receives a signal from the Asia synchronous communication port within the CPU and converts the data into an optical signal, and an infrared light emitting LED is used.

14 is its current limiting resistor, and 9 is a driver.

8 is a buzzer that emits a confirmation sound when the barcode data read by the reading section 5 is correctly decoded. 10 is the driver. Regarding the control program in the ROMI, the decoding process which is the main function of this barcode reader will be described later.

FIG. 20 shows the internal circuit of the reading section 5.

16 is a light emitting element (LED), and 15 is its current limiting resistor. The light from the light emitting element 16 is reflected from the medium (sheet) 17 on which the barcode is printed, and
The light enters the light receiving element (photodiode) 18. The photocurrent of the light receiving element 18 is converted into a voltage by a current-voltage converter AMP19. 21 is a resistor that determines the amplification factor, 2
0 is a capacitor that removes noise components. The output of the current-voltage liquid IAAMP 19 is input to the AMr' 23 and amplified. 22 is a non-inverting input resistor, and 24.25 is a resistor that determines the amplification factor. The output of AMP 23 is input to the inverting input of comparator 27 via input resistor 26 . A non-inverting input of the comparator 27 is connected to a resistor 28.
A threshold voltage created in step 29 is input, and when the input is lower than this voltage, the output is at pi level, and when it is higher than this voltage, the output is at low level. 30 is a resistor for providing hysteresis to the comparator 27. The output of the comparator 27 is outputted via an output terminal 31 to the one-up μCPUI. When the reading unit 5 is scanning a part of the black bar, the photocurrent is very small, so the comparator inversion input voltage is lower than the threshold voltage, and the output 31 is at a high level.

FIG. 21 is a block diagram of the main body control section 101.

The main body control unit 101 consists of a μCPU 32, a normal operation unit 33, a keyboard/display interface 34, and a ROM.
35, RAM 36, a parallel interface 38 that exchanges signals with each sensor in the copying process, the switch 40, and each load 41, a receiving section 39 that receives a transmitted signal (transmitted light) from the barcode reader 100, a receiving section 3
Serial interface 3 that converts the serial signal received at 9 into a parallel signal with timing.
It is made from 7.

The main body control unit 101 determines which mode input the data input from the serial interface 37 is, that is, which key input on the operation unit 33 is the same, and when it is determined correctly, a confirmation sound is emitted. Except for turning on the confirmation sound with a buzzer (not shown), the control is performed in exactly the same way as when the mode is input from the key on the operation unit 33.Therefore, along with the confirmation sound, the mode confirmation display on the operation unit 33 displays the bar code. It lights up according to the mode entered in the reader.

FIGS. 22 and 23 show the basic structure of a barcode printed on a barcode sheet.

FIG. 22 shows the configuration of only a two-digit mode code, and FIG. 23 shows the configuration of a two-digit mode code and a data section (one digit) accompanying the mode code. Keys or special modes on the operation section of the copier main body are encoded into a bar code having the structure shown in FIG. 22 or 23.

Figure 24 is table 1 of codes for keys or special modes.
Department.

For example, the #5# key in the tincture is coded as "#O05", the upper tray selection is coded as "04", and the "manual density notch 4" is coded as 1033'. For special modes, mode two 11th digit is 16'~#9#
A code starting with is assigned. .

25 to 28 show how the barcode reader 100 prints a barcode printed in the configuration shown in FIG. 22 or 23.
This is a program flow to explain how decoding is performed.

When manually scanning a barcode, there are two ways to correctly determine the code, in response to the expansion and contraction of the reading output signal waveform due to differences in scanning speed: the first pulse width detection method and the overall width detection method. However, in the present invention, the former is adopted.

To roughly explain the overall flow, it can be divided into four parts. The first part is the detection of the first pulse width, the second part is the detection of the start code, the third part is the detection of 2 or 3 character codes, and the fourth part is the detection of the stop code and the code. decoding data and storing decoded data in memory.

In the first part, the pulse width is determined by counting the read signal (high level) of the first large bar of the start code using the internal CLK (output from the timer/counter 54). Therefore, the CLK counter is first reset.

The timer TMO provides timing for stopping the decoding operation when the signal level does not change for a certain period of time, or for determining whether the read signal has normally ended. Since the barcode has the configuration shown in Figure 22 or Figure 23 above, if there is no change in level before the number of pulses reaches a constant value, decoding is stopped (this flow returns) and the number of pulses remains constant. Is the stop code coming when the value is (
Therefore, it is always reset before determining a level change.

First, check whether the first pulse has arrived or not, that is, the level change (L
-H), and if there is a level change, the width of the first pulse is curranted.

When the level changes to HL and the first pulse ends, it is determined whether the count value is within a certain range. This determination determines whether the barcode reader scan speed is within a certain value or if the first pulse is not a regular code due to dirt or the like. Next, change the width of the subsequent pulse (high level or low level) to a large bar (“1
In order to determine whether the bar is large or thin (“0”), the CLK number of the first pulse is multiplied by a constant of 2, 3, or 4 to give a dark value for determining whether it is a large bar or a thin bar. TeKS, KM, KL
is determined.

The relationship between KS, KM, and KL is shown in FIG. 1st
If the second pulse width following the pulse is between KS and KMO, it is a thin bar (#0"), and if it is between KM and KLO, it is a large bar ("1'). For the value of 4, it is necessary to choose the optimal value.

When the level changes to L-4H and the count of the second pulse ends, it is determined whether the second pulse is a thin bar (#0'') (is it the second pulse of the start code). When the level changes to HL and the third pulse count ends, it is determined whether the third pulse is a thick bar ('1') (is it the third pulse of the start code)? When the start code is read correctly, the data counter CD (indicating the pulse number of the character code) is reset, and the address counter AD (indicating the memory address where the read character code is stored) is set to 5. When set, character code decoding begins.

Decoding of each of the five character code pulses: high level, low level, high level, low level, and high level (Large bar → #1#, thin bar →
When the #O "decoding" is completed, the data counter CD is reset again and the address counter AD is incremented.

Then, the next character code is decoded. In this way, the character code is decoded two or three times, and the stop code is also decoded as the character code that follows them. However, if it is a regular stop code, there is no pulse following it, so the character code cannot be decoded. The routine is exited and the final decoding is performed, that is, the character code of 2OUT-OF5 is decoded into a normal binary code. C for 2-digit barcode
Since the A code is 5+2, it is determined whether the data of 5+2 is 03H1, that is, a stop code in the CA code. If it is a stop code, decode the 2OUT/OF5 code of 5 and 5+1 into a binary code at the address where the character code is stored, store the binary data to a specific memory address, and turn on the buzzer to confirm that the decoding is completed. Finish this flow. In the case of a 3-digit barcode, CA- is 5+3, so it is determined whether the data of 5+3 in CA- is 03H. When the stop code is determined, 5 is added to the address where the character code is stored, and 5+1 is added to the address where the character code is stored. The 5+2 2OUT-OF5 code is decoded into a binary code. Decoding at this time is shown in FIG. 30A or FIG. 30B.

FIG. 31 shows another structure of the barcode used in the copying machine of the present invention.

Figure 31A shows a configuration with only one digit in the mode section, and Figure 31B
The figure shows the configuration of a mode part of one digit and a data part of one digit. Since the mode part and data part are 2 digits in total, it is possible to set 100 types of codes.

FIG. 32 is a block diagram of a control unit including a barcode system according to another embodiment, which may be used in the copying machine of the present invention.

The barcode reader has a reading section 5 (l) and is supplied with power from the main body through a line 48.

The decoding section and memory section are located within the main body control section.

The reading section is composed of a circuit similar to that shown in FIG. 20, and its output signal 49 is directly input to the timer/counter part 47 of the main body control section. The processing of the input signal can be considered to be the same as the method described before Fig. 30, but since the signal from the reading section 50 is directly input to the main body control section, there is no need for a transmitting/receiving device or a control program. It is.

42.45, 4 and 6.51 to 53 are similar to the device described in FIG. 21, but 43.4-4 is partially different. That is, basically, the operating section 43 does not require any manual keystrokes and consists only of a display section. The machine is configured so that mode settings can be made only by inputting from the barcode reader, making the machine more compact and novel.

(Effects) The present invention is as described above, and according to the present invention, the cost is lower than that of conventional editors, it does not require space because it can be placed anywhere, and input can be done from a location away from the copying machine, so it can be used on a desk etc. This has the effect of allowing you to operate while thinking.
