The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of this device.
A sub-scanning width signal (a signal indicating a recording width in the sub-scanning direction) from a reference signal generating circuit 11 that generates a reference signal necessary for outputting a character or a bar code which is management information,
A main scanning width signal (a signal indicating the recording width in the main scanning direction) and a clock signal (a signal of 1 pulse for 8 pixels) are generated. Referring to FIGS. 7 and 8 showing timings in the main scanning direction and timings in the sub scanning direction, these reference signals are output from the timing generation circuit 12, the character generation circuit 13, the main scanning expansion circuit 16 and the character code storage circuit 14. It becomes the standard of operation.

The timing generation circuit 12 determines the recording start position of the character in the main scanning direction and the sub scanning direction and supplies it to the character generation circuit 13. Also, the interval between characters is determined and supplied to the character code storage circuit 14. Character generation circuit 13
Then, a character is generated so that it can be recorded at a predetermined position according to each reference signal.

The character code storage circuit 14 stores the character code of the character generator, which stores the characters required for the management information, in the memory (RAM) before recording, and stores it when recording the characters. The generated character code is supplied to the character generator of the character generation circuit 13. The character data output from the character generator is exchanged by the main scanning enlarging circuit 16 for a character having a magnification set by the CPU 15. The CPU 15 controls each circuit described above.

Each circuit will be described below. FIG. 2 shows a block diagram of the timing generation circuit 12. Sub-scanning width signal, main scanning width signal and clock signal are received from the reference signal generating circuit 11 from terminals 201, 202 and 203, respectively. The sub-scanning timing generation circuit 21 starts counting by the main scanning width signal after the sub-scanning width signal becomes valid (within the recording section). Then, the CPU 1
When the value set in 5 (recording start position in the sub-scanning direction) is reached, a sub-scanning recording start signal is output from the terminal 205 (see FIG. 8).

Similarly, the main scanning timing generation circuit 22 starts counting by the clock signal after the main scanning width signal becomes valid (within the recording section) (see FIG. 7). When the value set by the CPU 15 in advance (recording start position in the main scanning direction) is reached, a main scanning recording start signal is output from the terminal 206. Further, in this circuit, a signal designating the character interval is repeatedly output from the terminal 207 by repeatedly counting the value (interval of each character) set in advance by the CPU 15 (see FIG. 7). Since the recording start position is set by the CPU 15 (software), it can be arbitrarily designated from the operation panel or the like.

FIG. 3 shows a block diagram of the character code storage circuit 14. Before the start of recording, the switching circuit (1) 31 is opened by the memory control circuit 35, and the character code serving as management information is received from the terminal 301 from the CPU 15 and stored in the memory 33. At that time, the counter 34 causes the memory control circuit 3
The command of No. 5 operates at a speed at which the character code can be stored in the memory 33. Next, when recording the management information, the switching circuit (1) 31 is closed by the memory control circuit 35,
The switching circuit (2) 32 is opened. When the main scanning width signal supplied from the terminal 202 is valid (within the recording section), the character interval designating signal supplied from the terminal 207 is received, and the character code is stored in the memory 33 at a speed corresponding to the character interval.
From the terminal 30 via the switching circuit (2) 32.
2 (see FIG. 7).

If the time value is stored in the memory 33 in real time other than during recording, the time is recorded in the management information and can be managed in real time.
When outputting a bar code, the character code is set so that “white” is output, and at the same time, the black and white information of the bar code is received from the terminal 303 from the CPU 15 and stored in the memory 33 together with the character code. Then, at the same time as reading the character code from the memory 33, the black and white information is output to the terminal 304. FIG. 13 shows a relationship diagram between a barcode and black and white information. In the figure, 71 is black and white information for one line, and 72 is a bar code.

FIG. 4 is a block diagram of the character generation circuit 13, and FIG. 5 is a block diagram of a character generator used for this. 701 is black and white information for one line, and 702 is a bar code. Here, a case of using a 24 × 24 dot character generator will be described for simplicity, but the same processing can be performed for other dot numbers.

The character generator of 24 × 24 dots has a table of 8 bits (main scanning) × 24 lines (sub scanning) as shown in FIG. 9, and with three ICs as shown in FIGS. One character is made up. Therefore, I
A signal for selecting C and a signal for selecting one line out of 24 lines are required.

The IC selection circuit 41 outputs a signal for selecting the above-mentioned IC. In this circuit, the main scanning enlargement counter 44 receives the output, the main scanning recording start signal is valid,
The IC selection signal is sent to the character generator 43 only when the sub-scanning recording start signal is valid. At this time, the main scanning enlargement counter 44 receives a main scanning recording start signal from the terminal 206, a clock signal (a signal of 1 pulse for 8 pixels) from the terminal 401, and a terminal 404 (CPU 15) to receive a character enlargement ratio designating signal in the main scanning direction. The frequency division value of the clock supplied to the IC selection circuit 41 is determined according to the enlargement ratio. FIG. 11 shows an example in which the enlargement ratio is 3 times.

A signal for selecting one of the 24 lines is output from the line counter 42. This circuit operates the counter by the output from the sub-scanning enlargement counter 45 only when the sub-scanning recording start signal received from the terminal 205 is valid, and outputs the output from the character generator 4
Send to 3. Here, the sub-scanning enlargement counter 45 is connected to the terminal 4
02 main scanning width signal and the terminal 405 (CP
U15) receives a character enlargement ratio designating signal in the sub-scanning direction, and determines the frequency division value of the clock supplied to the line counter 42 according to the enlargement ratio. For example, 4 in the sub-scanning direction
In the case of doubling, it is sufficient to supply a 1/4 clock.

In the character generator 43, the above 2
In addition to the signal of the type, the character code is received from the terminal 302, and the data of the specified character is output to the terminal 403. In FIG. 5, character generator ROMs 51 and 5
2, 53 (IC1, IC2, IC3) are 51 → 52 → 53 → 51 → 52 → 53 → 51 by a select signal from terminals 502 to 5049 supplied from the selection circuit 41.
... is selected. The sub-scanning direction is designated by the counter value sent from the line counter 42 from the terminal 501. When the enlargement is performed, the designation of the main scanning direction and the sub-scanning direction is extended according to the magnification. As an example, FIG. 10 shows the output state of the character generator in the case of being doubled.

When outputting a bar code, the terminal 3
The black and white information is received from 04 and supplied to the black and white inverting gate circuit 54. Since white is always output from the character generator ROMs 51 to 53 (the character codes are all set to "white"), gate processing is performed with the black and white information to obtain a black and white signal having bar code information.

FIG. 6 shows a block diagram of the main scanning expansion circuit 16. When enlarging a character, in the sub-scanning direction, the reading designation in the sub-scanning direction of the character generator 43 is simply performed a plurality of times in succession (for example, three times when the magnification is 3 times), and the reading is completed. However, in the main scanning direction, when the character generator 43 is accessed once, 8 dots are simultaneously output. Therefore, a regular character cannot be output by simply performing the main scanning direction read designation a plurality of times in succession. Therefore, the main scanning expansion circuit 16 converts the data so that the data is continuously output a plurality of times in units of one dot in the main scanning direction.

Specifically, referring to FIG. 6, first, the data select counter 61 is connected to the terminal 406 (the character generating circuit 13).
The clock frequency division value in the main scanning direction is received, and the counter is performed with the clock signal (a signal of 1 pulse for 8 pixels) sent from the terminal 602 within that range. As an example, FIG. 12 shows the operation timing of the data selector counter with a magnification of 3 times. The counter output is sent to the enlargement ratio storing ROM, and as shown in FIG. 14 (as an example, the case where the enlargement ratio is 3 times is shown), the character data is output according to the enlargement ratio designated by each of the enlargement data selectors 63 to 70. . In the table of FIG. 14, 00 to 47 are 1-bit data sent from the terminal 601.

As described above, according to the present invention, (a) management information can be recorded for a large amount of image data to be output, so that it can be easily arranged. (B) The function of the clock can be added by rewriting the character code as the management information in real time, and the management can be performed in real time. (C) Basic clock (signal of 1 pulse for 8 pixels)
On the other hand, it can output enlarged characters and is versatile. (D) The recording start position of the character and the enlargement ratio of the character are displayed by the CPU.
Since it can be controlled by (software), the management information can be easily recorded at an arbitrary position by designating the position designation and enlargement using the operation panel or the like. (E) A circuit for outputting characters can be diverted as it is to output a barcode, and it is not necessary to add a separate barcode output circuit, so that a function can be added without increasing the circuit scale. .

As described above, according to the present invention, it is possible to easily record management information at an arbitrary position for a large amount of image data to be output, and to use this as enlarged characters,
There is an effect that can be output as a barcode.
