Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables
The present invention relates to a recording device that records identification marks on the recording paper.

In a recording device such as a computer that records and outputs data, output information is recorded and output on recording paper such as fan-hold paper or cut sheet, and the number of output sheets is often large at one time. Furthermore, the content of the output data is often the result of multiple jobs, and the types of output information are often multiple.

Therefore, it is conceivable to record a page number 13 and a classification code 14 (hereinafter referred to as a sorting code) on each page of fan-hold paper 11 and cut sheet 12, as shown in FIGS. 1A and 1B.

The recording sheets on which information and organizing symbols have been recorded in this manner are handled by being stacked or bound as shown in FIG. 1C. When the sheets are stacked in this manner, it becomes impossible to read the ordering marks on the individual pages of the recording paper, and only the ordering mark on the first page can be observed.

Therefore, as shown in FIG. 1C, it is best to take out only the recording sheets belonging to specific information, such as a plurality of recording sheets 15-1 for information 1, a plurality of recording sheets 15-2 for information 2, etc. It becomes difficult.

The present invention relates to a recording device that eliminates the above-mentioned conventional drawbacks, makes it possible to easily distinguish between sections of information even when recording sheets are stacked, and makes it easier to handle a large number of sheets of recording paper. be.

Processes multiple jobs each consisting of multiple pages of character code information, records a recording pattern corresponding to the character code on recording paper, and transfers the image on the recording body onto the fed recording paper. In the recording apparatus, a marker code generating means (black code signal generator 59) generates a marker code indicating a marker, and a predetermined edge of the recording paper extending in a direction perpendicular to the feeding direction of the recording paper for each job. Marker position generating means (counter 36, first line indicator 53) for generating recording position information of the mark consisting of a row address and digit address corresponding to the predetermined position in order to record the mark at a position, the character code and A dot generating means (dot pattern generator 23) that generates a dot pattern according to the marking code, a beam generating means (semiconductor laser 44) that generates a beam according to the dot pattern, and a scanning means (scanning means) that deflects and scans the beam. A rotating polygon mirror 45), a beam detection means (beam detector 46) that detects the beam at a predetermined beam scanning position for each scan of the scanning means, and a clock generation means (clock signal generator) that generates a clock of a predetermined frequency. 55) Address determining means (scanning line counter 41, row addresser, digit counter 57, digit addresser 58), the sign code is read at the sign recording position where the row address and digit address obtained by the address determining means match the row address and digit address of the recording position information of the sign of the sign position generating means. control means (matching circuit 60, gate 54) for controlling the dot generating means to record a marker dot pattern corresponding to the dot pattern;
The object of the control means is to provide a recording apparatus that records the marker dot pattern along the edge of the recording paper in the recording area of the character code information.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram showing an embodiment of a recording device according to the present invention. A page buffer memory 22 (hereinafter referred to as
A recording signal read out from this PBF 22 is applied to a pattern generator 23 to be converted into a dot pattern signal, and a semiconductor laser generator 44 is controlled by the dot signal read out from this pattern generator 23. The laser beam 24 is modulated by the laser beam 24, and a recording pattern corresponding to a recording signal is recorded on the photoreceptor 25 by the modulated laser beam 24.

What is indicated by 30 in FIG. 3 is the file 21.
The header area 31-1 of this magnetic tape 30 stores an information start signal (for example, code signal Z) indicating that the first type of information is stored. Following the index area 31-1, recording signals belonging to the first type are stored for each unit area 32-1 to 32-n. That is, each unit area is an area for storing the amount of recording signals to be recorded on one page of recording paper, which will be described later, and in each unit area, the recording signals are stored sequentially from left to right in the figure in the form of code signals. This is what is being done. In exactly the same way, the header area 31-2 stores an information start signal (for example, code signal Z) indicating that the second type of information is stored, and the header area 31-2 is followed by the above-mentioned information. A recording signal belonging to the second type of information is stored in each unit area 33-1 to 33-m. Similarly, information start signals are stored at the boundaries of information types.

Therefore, when information is read from the file 21 under the control of the read control circuit 27, an information start signal is first read onto the signal line 28.

A signal detector 26 detects the information start signal read out in this manner, and derives one pulse on the signal line 29 by detecting the information start signal. These pulses are applied to a counter 36 and counted by the counter 36.

Therefore, the contents of the counter 36 change from 0 to 1 when the heading area 31-1 is read. However, such information start signal is PBF
22 is not stored.

When reading of the magnetic tape 30 continues,
Information signals within the unit area 32-1 are sequentially read out, and these information signals are sequentially written into the PBF 22 controlled by the address circuit 37.

This PBF 22 has a storage area of 136 x 66 as shown in Fig.
The recording area 38 is specified by the Y address of , and each recording area 38 stores one character code signal or one graphic code signal.

In FIG. 4, the character code signals are shown in the form of characters to simplify the explanation.

The write control by the address circuit 37 to the PBF 22 is performed when Y=1 and X=1, as shown in FIG.
Write X=2, ..., X=136, then Y=2
Then, X=1, X=2, . . . , X=136, and so on.

In this way, the address circuit 37 sets X=136, Y
=66, the page end circuit 35 detects this address, derives a page end signal on the signal line 39, controls the read control circuit 27, and stops reading information from the magnetic tape 30. do. accordingly
In the PBF 22, for example, as shown in FIG. 4, information signals of a unit area 32-1 are stored.

In this way, when a recording command signal is applied to the terminal 40 while a predetermined recording signal is stored in the PBF 22, the address circuit 37 is brought into the initial state, and the scanning line counter 41, row addresser 42,
1st row indicator 53, counter 53, digit counter 5
7. PBF2 that sets the digit addresser 58 to the initial state
The reading of the recording signal from 2 is performed using the digit addresser 58.
The output of the row addresser 42 is used as the X address, and the output of the row addresser 42 is used as the Y address.
Before explaining such reading, the configuration of the recording device will be further explained.

Reference numeral 43 indicates a recording section, and this recording section 43
For example, Japanese Patent Application Laid-Open No. 51-93219 filed by the present applicant
It consists of the configuration as explained in
The laser beam 24 generated by the semiconductor laser generator 44 is deflected in the direction of the arrow G by being deflected by a rotating polygon mirror 45 that rotates in the direction of the arrow F at a constant speed.

A beam detector 46 outputs a pulse signal (beam detection signal) onto a signal line 47 every time the laser beam 24 is incident on the beam detector 46 . The photoreceptor 25 is a drum-shaped photoreceptor widely used in electronic copying machines and the like, and rotates at a constant speed about a rotating shaft 48 .

Therefore, the semiconductor laser generator 44 is connected to the signal line 4.
If ON-OFF control is performed using the dot signal on the photoreceptor 9, a beam irradiation trace of a recording pattern corresponding to the recording signal will be formed on the photoreceptor 25.

Therefore, as used in electronic copying devices, an electrostatic latent image is formed on the photoreceptor 25 in response to beam irradiation, this latent image is visualized with a developer, and then the developed image is transferred onto transfer paper. If it is transferred, desired information can be recorded on recording paper.

As mentioned above, the laser beam 2 is on the signal line 47.
A beam detection signal is derived each time 4 scans the photoreceptor 25 in a direction parallel to the rotating shaft 48, and a scanning line counter 41 counts such beam detection signals row by row. Then, the counting output is derived.

That is, on the recording paper 50, the PBF 22
The information inside is recorded in the form shown in FIG. 5, and the top, bottom, left, right,
At the edges, there is a top margin of 70, a bottom margin of 71, and a left margin of 7.
2. Recording is performed with a right margin 73 left, and a column margin 74 is left between columns, and a row margin 75 is left between rows.

FIG. 5B shows an enlarged view of the upper left end of the recording paper 50 shown in FIG. 5A, but in the embodiment, a left margin corresponding to three columns is formed at the left end of the recording paper 50, A top margin corresponding to three lines is formed at the top end.

To explain in more detail, in this embodiment, the character area allocated to one character or figure is 20×
It is composed of 30 dots, and the column margin between columns is equivalent to 5 dots, and the row margin between rows is equivalent to 10 dots. ing.

Therefore, the scanning line counter 41 is connected to the signal line 47.
The beam detection signals DP as shown in FIG. 6A, which are sequentially derived above, are counted until they reach 40, but the count value is not derived to the signal line 51 when the count value exceeds 31. Therefore, the output signal of the scanning line counter 41 is as shown in FIG. 6B.

Reference numeral 42 indicates a counter that counts the output of the scanning line counter 41 to count the number of lines in which information is to be recorded. After the preset row is applied, the counted rows such as the first row and the second row are connected to the signal line 5.
2.

For example, in the example shown in FIG. 5, the line counter 42 does not derive an output between blank lines b-1 to b-3, and the line L-- where recording is actually performed.
1, L-2, L-3, ..., 1,2,
It outputs the counted value as 3,... Therefore,
If the output of the scanning line counter 41 is as shown in FIG. 6C (FIG. 6B and C are the same signal), the output of the row counter 42 is as shown in FIG. 6D, indicated by the dotted line. The counter output is not derived between b-1 and b-3.

Reference numeral 53 indicates a first row indicator to which the output of the scanning line counter 41 is applied, and gates a high level signal only during the first row indicated by b-1 in FIGS. 5 and 6. 54.
Therefore, the output of the first row indicator 53 is as shown in FIG. 6E. Reference numeral 55 indicates a clock signal generator, and the clock signal derived from this clock signal generator 55 corresponds to one dot recorded on the photoreceptor 25 by the laser beam. It takes 20 clock signals to scan one character area indicated by 60 in FIG. 5 in the X direction.

The clock signal generator 55 receives the beam detection signal from the beam detector 46 shown in FIG. 7A.
Since it is activated by the DP as shown in FIG. 7B, the phases of the beam detection signal and the clock signal are exactly the same.

This clock signal is controlled so that it is applied to the next stage digit counter 57 only after the counter 56 has counted a predetermined number.

That is, as is clear from FIGS. 2 and 5, the beam reaches the recording start end S after a certain period of time has elapsed since the beam was detected by the beam detector 46. As shown, the counter 56
In this case, the time required for the beam to reach the recording end is counted, and after counting, a clock signal is applied to the digit counter 57 at the next stage. Therefore, if the count value N by the counter 56 is made variable, the size of the margin formed on the left side of the recording paper can be freely selected.

The digit counter 57 counts the clocks corresponding to one character area 69 (20 clock signals in this embodiment) as shown in FIG. 7D, and does not derive the 5 clock signals between character areas. be.

The output of the digit counter 57 is further applied to a digit addresser 58 to derive digit address signals CP-1, CP-2, . . . as shown in FIG. 7E, but this digit address signal is designated as CP-1. Count value 1 is CP-
2 is the count value 2, CP-3 is the count value 3,
The counted value is output as follows. Reading out the information signal from the PBF 22 is as follows:
The digit address signal derived from the digit addresser 58 is read out as the X address of the PBF 22 detailed in FIG. 4, and the row address signal from the addresser 42 is read out as the Y address of the PBF. In this embodiment, in order to record the mark, the output of the digit addresser 58 and the output of the counter 36 are applied to a matching circuit 60, and only when the counting outputs of the counter 36 and the digit addresser 58 match, A high level signal is derived from the matching circuit 60 onto the signal line 61. This signal line 61 and the first
The output of the row indicator 53 is further applied to the gate 54, and the gate 54 is opened only when the two applied signals are high level signals first, and the black code signal generated by the black code signal generator 59 is output. The signal is controlled to be applied to the pattern generator 23.

This pattern generator 23 derives a pattern composed of dots, and as is well known, it applies a code signal indicating a character, figure, etc., and also determines the scanning line number of the character or figure. By applying a scanning line number indicating the code signal, dot signals corresponding to the specified scanning line are derived in parallel with characters or figures corresponding to the code signal. Therefore, by applying the dot signals derived in parallel to the shift register 63 and applying the clock signal as a shift signal to the shift register 63, a dot signal converted into a serial signal can be obtained on the signal line 49. It is possible.

To further explain the recording operation of the recording apparatus having the above configuration, as described above, the terminal 40
When a recording command signal is applied to the first beam detection signal, the output of the first row indicator 53 becomes high level, but the row addresser 42 derives the beam detection signal (30+10)×3 as described above. 0 until
remains retained.

When the beam that has passed through the beam detector 46 is further deflected and reaches the recording start end S, a count value "1" is derived from the digit addresser 58, as shown in FIG. The outputs of the row addresser 42 and digit addresser 58 are applied to the circuit 37 as Y address and X address, respectively, but as mentioned above, the output of the row addresser 42 is "" until 120 beam detection signals are derived. 0", so during this time (between blank rows b-1 to b-3 in Figure 5B)
No information signal is read from the PBF 22.

However, the count value of the counter 36 is 1
And, as mentioned above, the count value of the digit addresser 58 is also 1, so the output of the coincidence circuit 60 becomes high level. Furthermore, since the output of the first row indicator 53 is also at a high level, the gate 54 is opened and a black code signal is applied to the pattern generator 23. This black code signal instructs the generation of a dot pattern such that the entire 20×30 character area 69 is filled with black dot signals. Since a scanning line signal indicating the first scanning line is applied to the pattern generator 23 via the signal line 62, a high level signal "1" representing a black dot is derived on the output lines 64-1 to 64-20. Ru.

When 20 clock signals are applied to the shift register 63 in this state, the 20 "1" signals in the shift register 63 are sequentially read out and applied to the semiconductor laser 44, causing the semiconductor laser 44 to become "1".
It turns on and generates a laser beam in response to the signal applied. When 0 is applied, the semiconductor laser generator 4
4 is OFF.

After 20 clock pulses are derived in this way, if further clock pulses are derived, then
As shown in FIG. 7E, the derivation of the count output from the digit addresser 58 is stopped for five clock pulses, and by applying further clock pulses, the output of the digit addresser 58 becomes "2", "3", etc. As it increases, the output of match circuit 60 goes low and the derivation of the dot output from pattern generator 22 is stopped.

That is, in the first scanning line of the first blank row b-1, the laser beam is irradiated onto the photoreceptor only during the period corresponding to the position shown in column 64 in FIG. 5B. In this way, the first blank row
When the scanning of the scanning line is completed, scanning of the second scanning line begins. When the beam is detected by the beam detector 46, the scanning line counter 41 applies a count value "2" to the pattern generator 23.

When the beam 24 reaches the recording start end S in this state, the count value "1" is again derived from the digit addresser 58, and a black code signal is applied to the pattern generator 23. A signal "2" indicating the second scanning line is applied to the pattern generator 23, but since the black pattern signal corresponding to the black code signal is composed of a 20x30 black dot signal, the second scanning line is applied to the pattern generator 23. Output lines 64-1 to 64-20 as in the case of one scanning line
A "1" signal is derived to control the semiconductor laser generator 44 in the same way as in the first scanning line.

Thereafter, recording is performed in the same manner until the scanning of the 30th scanning line of the blank first row b-1 is completed, and the upper edge of the recording paper 50 is shown as 64 in FIG. 5B. An indicator is recorded in the first column position. Next, the blank first row margin bb-1 is scanned, but in this margin, the output of the digit addresser 58 is not derived as shown in FIG. Since the value changes, the coincidence circuit 60 does not operate and no recording is performed.

When the scanning of the first blank first row margin bb-1 is completed and the scanning of the second blank row b-2 begins, as is clear from FIG. 6E, the first row indicator 53
Since the output of is held at a low level, the coincidence circuit 60 does not operate and no recording is performed.

Since the first row indicator does not operate in subsequent rows, no black pattern is recorded by the black code signal generator 62 thereafter. In this way,
When the first recording row is reached, the row addresser 42 applies a count value "1" indicating recording row L-1 to the address circuit 37 as a Y address, and the digit addresser 58 outputs 1, 2, 3, . . . Since the count values indicating the digit positions are applied to the address circuit 37 as the X address in order, the contents of the PBF 22 are changed to A, B, C,
... (However, it is a character code signal) is read out and applied to the pattern generator 23. Since the scanning line signal is applied to the pattern generator 23 from the scanning line counter 41 as described above, the dot signals belonging to the designated scanning line are led to the shift register 63 and read out sequentially from the shift register 63. The semiconductor laser generator 4 is activated by the dot signal.
4 is controlled.

Note that a character code signal and a scanning line signal are applied to a pattern generator to derive a parallel dot signal,
The technique of sequentially reading out these dot signals, modulating a laser beam, and recording information on a photoreceptor using the modulated beam was disclosed in the above-mentioned Japanese Patent Laid-Open No. 51
93219, so
A detailed explanation will be omitted here. like this
When the recording of all the information signals in the PBF 22 is completed, the page end circuit 35 detects that the recording has ended and controls the read control circuit 27.
The unit storage area 32-2 on 0 is read into the PBF 22. Since the signal detector 26 does not detect any information start signal when reading this unit storage area 32-2, the content of the counter 36 remains "1".

After that, if a recording command signal is applied to the terminal 40, the mark 64 is placed in the first column of the first blank row in the same manner as described for recording the first page.
is recorded.

In short, all the recording sheets on which the recording signals belonging to the unit storage area 32 are recorded are located at the same location (in the embodiment, the position belonging to the first column at the top end of the recording paper).
The mark 64 is stored in the .

In this way, if recording of the first information is finished and then reading of the second information is started, the area 31 of the magnetic tape 30 -
By reading out the information start signal of 2, the signal detector 26 detects this signal, so the counter 36 increments and its content becomes "2".

Therefore, on the recording paper recording the contents of the unit storage area 33-1, the marker is blank in the first row b.
The mark is recorded in the second column of b-1 in the blank first row b-1, and in all of the recording sheets on which the unit storage area 33 is recorded in the same way thereafter, the marker is recorded in the second column of the blank first row b-1. It is something.

In this way, in the recording device shown in Fig. 2,
The recording paper that belongs to the first information is identified in the first row of the edge of the recording paper, the recording paper that belongs to the second information is identified in the second row, and so on. Since the marks are recorded, even if the recording sheets 50 are stacked as shown in FIG. 8, the type of information can be easily identified by the position of the marks 64.

In the above embodiment, the same information start signal, such as the code signal Z, is stored in each heading area, but in other embodiments, the information start signal may be changed depending on the information. It is okay to do so.

For example, in FIG. 3, the information start signal "1" is applied to the heading area 31-1, the information start signal "2" is applied to the heading area 31-2, and the information start signal "3" is applied to the heading area 31-3. ”, the counter 36 in FIG. 2 is configured with a buffer memory and receives the information start signal, “1”, “2”, “3”.
. . . should be stored sequentially.

As described in detail above, in the recording apparatus according to the present invention, even when recording papers on which information is recorded are stacked, the boundaries of the information can be identified as they are, so that processing of the recording papers becomes extremely easy.
