FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. Reference numeral 1 indicates an operation panel, which includes an attribute setting device for specifying image attributes such as the number of scanning lines and aspect ratio for each input image signal, and an arrangement for specifying the output image array position. A setting device is provided, and each piece of information set on the operation panel 1 is input to a microcomputer 2 that constitutes a part of the image output device and controls the image output device.

The microcomputer 2 reads the attribute information and arrangement information output from the setting device of the operation panel 1, and performs interlacing/non-interlacing according to the image signal acquisition start signal, image signal sampling frequency setting information, and input attribute information. Interlace, import/read information, write start address information, odd field/even field information, rotation information along with placement information, left/right or top/bottom read start address, right margin dot number information when outputting, left margin Outputs dot number information, center margin dot number information, right image dot number information, and left image dot number information.

Further, the ROM of the microcomputer 2 stores image number information obtained by developing image numbers (1, 2, . . . ) attached to the vicinity of recorded images, and image number information obtained by developing image numbers rotated by 90 degrees. It has been done.

The image signal is input to the A/D converter 4, and the A/D converter 4 receives the image signal.
The D converter 4 performs A/D conversion. The sampling of the image signal in the A/D converter 4 is performed in accordance with the oscillation output of the frequency synthesizer 5 whose frequency division ratio is set according to the image sampling frequency setting information, that is, the sampling clock signal. The image signal data of the sampled image signal is stored in a frame memory 6 controlled by an address control section 8 controlled by a capture position control section 7.
The data is stored at the address in the first frame memory area 61 of the frame memory 6 specified by the address counter 9 which specifies the row direction address and column direction address. Here, the address designation is such that the image signal data for one horizontal scanning period is stored in the address of one row of the frame memory 6. Similarly, the A/D converted 2nd screen, 3
The video signal data of the screen are stored in the second and third frame memory areas 62 and 63 of the frame memory 6, respectively. Frame memory 6 further contains image number information and 90
An area 64 is provided in which image number information rotated by ° is stored.

The image signal data stored in the frame memory 6 is read from the address specified by the count value of the address counter 9 which receives the output of the clock pulse oscillator 14, and the read image signal data is sent to the selector 10. The data is stored in the line buffer memory 11 via the line buffer memory 11. The data stored in the line buffer memory 11 is read out and applied to the head driving section 12 to drive the head 13 and thermally record it on the recording medium.

On the other hand, the capture position control unit 7 receives a capture start signal,
Using the synchronization signal separated from the image signal and the sampling clock signal output from the frequency synthesizer 5, a capture control signal is guided to the address control section 8 from the time of input of the capture start signal and the synchronization signal. The address control unit 8 receives the sampling clock signal as a write pulse, receives the clock pulse output from the clock pulse oscillator 14 as a read pulse, selectively outputs it to the address counter 9 in accordance with the capture/read signal, and selects the selector 15. Outputs a control signal to. The selector 15 receives the control signal, and in response to the interlace/non-interlace signal, the rotation instruction signal, and the odd/even instruction signal, the selector 15 outputs a write start address for interlace, a right image read start address for read, One of the left image readout start addresses is selected and supplied to the address counter 9 as preset data to designate the address at the start of readout.

The area identification unit 18 receives the output from the dot number counter 16 and outputs an output that identifies whether it is a left margin area, a left image area, a center margin area, a right image area, or a right margin area on the recording medium. Accordingly, a control signal to the selector 10 and a control signal to the selector 17 are output. When the area identifying section 18 identifies the left margin section, the number of left margin dots is selected by the selector 17, the number of left margin dots is preset in the dot number counter 16, and the dot number counter 16 outputs it from the address control section 8. The area identification unit 18 counts down the readout clock pulses, and when the count value reaches 0, the area identification unit 18 identifies that the left image area has been reached. When the area identification unit 18 identifies the left image portion, the number of left image dots is selected by the selector 17, the left image dot number is preset in the dot number counter 16, and the dot number counter 16 outputs it from the address control unit 8. The area identification unit 18 counts down the readout clock pulses, and when the count value reaches 0, the area identification unit 18 identifies that the central margin area has been reached.

When the area identification section 18 identifies the center margin, the number of center margin dots is selected by the selector 17, the number of center margin dots is preset in the dot number counter 16, and the number of center margin dots is preset in the dot number counter 16. The area identification unit 18 counts down the readout clock pulses outputted from the area, and when the count value reaches 0, the area identification unit 18 identifies that the right image area has been reached. When the area identification unit 18 identifies the right image portion, the number of right image dots is selected by the selector 17 and the number of right image dots is stored in the dot number counter 16.
The dot number counter counts down the read clock pulses output from the address control section 8, and when the counted value reaches 0, the area identification section 18 identifies that the right margin section has been reached. When the area identification section 18 identifies the area as the right margin section, the number of right margin dots is selected by the selector 17, the number of right margin dots is preset in the dot number counter 16, and the number of right margin dots is output from the address control section 8 by the dot number counter. The area identification unit 18 counts down the readout clock pulses, and when the count value reaches 0, the area identification unit 18 identifies that one raster has been completed.

The period selector 10 that is identified as being in the left image portion by the area identifying unit 18 is the frame memory 6.
The period selector 10 selects the data from the frame memory 6 and outputs it to the line line buffer 11, and the period selector 10, which is identified by the area identification unit 18 as being in the right image part, selects the data from the frame memory 6 and outputs it to the line line buffer 11. At other times, data from the frame memory 6 is not output to the line line buffer 11. therefore,
In the line line buffer 11, white left margin data, image signal data accompanying an image signal placed on the left side,
The white center margin data, the image signal data placed on the right side, and the white right margin data are arranged side by side.

The operation of this embodiment configured as described above will be explained. It is assumed that the image stored first in the frame memory 6 is set to be recorded on the left side of the recording medium, and the next image stored on the right side of the recording medium, and the image signal has an effective number of scanning lines of 480. Assume that the aspect ratio is 3:4 and interlaced.

In the frame memory 6, the first, second, and third frame memory areas 61, 62, and 63 are divided as shown in FIG. The start address of area 61 is (V,
H)=(0,0), the start address of the second frame memory area 62 is (V,H)=(640,0), and the start address of the third frame memory area 63 is (V,H)=(128
0, 0).

[0021] In addition, when interlacing, the V address is set to 0, 2, 4, ... for odd fields and 1 for even fields.
, 3, 5, etc., and 0 for non-interlaced
, 1, 2, 3, etc.

When the power is turned on, the image number information stored in the ROM of the microcomputer 2 is transferred to the area 64 of the frame memory 6. The input image signal is A/D converted, and the effective part excluding the retrace period is A/D converted.
D-converted and 1 in the first frame memory area 61
The horizontal scanning period is sequentially stored in one row of addresses in the frame memory 6. The number of effective scanning lines for the image signal is 480.
Since the aspect ratio is 3:4 and it is interlaced, one horizontal scanning period is stored at addresses (0, 0) to (0, 639), and when storing the next one horizontal scanning period, the address is Stored at (2, 0) to (2, 639). In the same way, the data is sequentially stored and stored over one frame. In this case, when entering an even field from an odd field, addresses (1, 0) to (1, 639),
They are sequentially stored in (3, 0) to (3, 639), . . . A state in which storage for one frame is completed in this manner is shown by a hatched area A in FIG.

The first screen image signal also operates in the same way and is sequentially stored in the second frame memory area 62 in the same way. Since the image signal B has an effective number of scanning lines of 400 and an aspect ratio of 5:8, the first horizontal scanning period is stored at addresses (640, 0) to (640, 639).
The data for one horizontal scanning period is sequentially stored. Since the image signal B is non-interlaced, there is no need to switch between odd and even fields. At the end of one field, the image signal B is also stored as shown in the shaded area B in FIG.

When the storage of image signal data in the frame memory 6 is completed as described above, a read state is entered. When the read state is entered, the area identification unit 18 identifies the left margin area, the number of left margin dots 500 is preset in the dot number counter 16, and the clock pulses from the clock pulse oscillator 14 are sent to the dot number counter 16 by the number of left margin dots 500. When the area is counted, the area identification unit 18 identifies it as the left image area. The area identification unit 18 switches the selector 10 so as to lead the data from the frame memory 6 to the line buffer memory 11 during the period when the area is identified as the left image area. When the area identification unit 18 identifies the left image area, the address counter 9 is first read out the first raster portion of the vertical character "1" in the area 64 of the frame memory 6.
The first raster of 32 dots in which the vertical character "1" is developed is read out by the read clock pulse output from the clock pulse oscillator 14 and transferred to the line buffer memory 11. Upon completion of this reading, the area identification unit 18 identifies the center margin area, and the selector 10 is switched, and
The number of center margin dots, 536, is preset in the dot number counter 16 via the selector 17. Next, the dot number counter changes the read clock pulse to the center margin dot number 536.
When the area has counted down, the area identification unit 18 identifies it as the right image area. No input is selected for the period selector 10 that is identified as the center margin by the area identifying unit 18, and 536 pieces of white dot information are input to the line buffer memory 11. The address counter 9 is preset via the selector 15 in order to read out the first raster portion in which the vertical character "2" in the area 64 of the frame memory 6 is developed based on the identification with the next right image part. The first raster of 32 dots from which the direction character "2" is developed is read out, transferred to the line buffer memory 11, and stored following the center margin dots. The 500 dots after the first raster of the vertical character "2" are white as the right margin.

Line buffer memory 1 in this case
The storage contents of 1 are as shown in FIG.

When the reading of the first raster in which the vertical character "2" is developed is completed, the contents stored in the line buffer memory 11 are read out, the head driving section 12 is driven in accordance with the stored contents, and the head 13 is driven. It is thermally recorded on the recording medium.

Next, the second raster of the vertical character "1" is read out and similarly transferred and stored in the line buffer memory 11, and then, with a center margin, the second raster of the vertical character "2" is read out. The raster is read out, transferred and stored in the line buffer memory 11, and thermally recorded on the recording medium by the head 13.

Similarly, vertical characters "1" and "2"
” is read out, transferred, stored, and thermally recorded up to the last raster. At the end of this execution, as shown in Figure 3, vertical characters “ “
1" and "2" are recorded.

Following the completion of recording the vertical characters "1" and "2", the area identification unit 18 identifies the left margin area, and the number of left margin dots, 120, is preset in the dot number counter 16. When the dot number counter 16 counts the clock pulses from the clock pulse oscillator 14, the area identification unit 18 identifies the left image area,
The left image dot number 640 is preset in the dot number counter 16.

On the other hand, during the period when the area identifying section 18 identifies the left margin area, the selector 10 selects the non-input side, and the line buffer memory 11 stores white dot information at 120.
Dot is input.

When the area identification unit 18 identifies the left image portion, the left image readout start address number is selected via the selector 15 and preset in the address counter 9. In this case, the number of preset addresses is (0, 0). The address counter 9 is activated by identifying it as the left image area.
A clock pulse from the clock pulse oscillator 14 is supplied as a read clock pulse to the first row (addresses (0, 0) to (0, 63) of the first frame memory area 61).
The image signal data stored in 9)) is read out. Meanwhile, during this time, the area identification unit 18 switches the selector 10 to the output side of the frame memory 6, and the image signal data stored in read addresses 0 to 639 is written to the line buffer memory 11.

During this time, the dot number counter 16 is counting down with the readout clock pulse, and when it counts 640 dots, the area identifying section 18 identifies it as the center margin, and the dot number counter 16 via the selector 17 indicates that the center margin is the center margin. The number of dots is preset to 80, and the number of center margin dots is 8.
When the dot number counter 16 counts only 0 read clock pulses, the area identification section 18 identifies the right image portion, and the right image dot number 640 is preset in the dot number counter 16.

On the other hand, while the area identification unit 18 identifies the center margin, the selector selects the non-input side, and 80 dots of white dot information are input to the line buffer memory 11.

When the area identification unit 18 identifies the right image portion, the number of right image readout start addresses is selected via the selector 15 and preset in the address counter 9. In this case, the number of preset addresses is (640, 0)
It is. Upon identification of the right image portion, a read clock pulse is supplied to the address counter 9, and the first row (address (640, 0) to
(640, 639)) is read out. Meanwhile, during this time, the area identification unit 18 switches the selector 10 to the output side of the frame memory 6.
Read addresses (640, 0) to (640, 63
9) is written into the line buffer memory 11.

During this time, the dot number counter 16 is counting down with the readout clock pulse, and when it has counted 640 dots, the area identification unit 18 identifies it as the right margin area, and the dot number counter 16 receives the right margin dot number via the selector. 120 is preset, and the read clock pulse is applied to the dot number counter 16 by the right margin dot number 120.
When counted, the area identification unit 18 determines that one line has ended.

Next, the first and second frame memory areas 61
, 62 to read the second line. Reading of the second row is performed in the same manner as the first row, but when reading the second row of the first frame memory area 61, the address counter 9 is preset to address (1, 0), and the address (1,639) is read out. Furthermore, when starting to read the second row of the second frame memory area 62, it is preset to the address (641, 639), and the address (64
1,479).

As a result of the reading proceeding in this manner, the recording on the recording medium made by the head 13 becomes as shown in FIG.

[0038] If reading is continued as described above and only the left or right image is left, read out only one image's data by changing the number of left margin dots or center margin dots. good.

Furthermore, if the layout information specified by the setting device on the operation panel 1 instructs to rotate the image and display it, as shown in FIG. The first raster of "2" is read out, and then the first raster of the vertical character "1" is read out after the center margin. After the second raster, when the horizontal characters "2" and "1" are read out to the last raster, the first line (119, 0), (1
18, 0), ... (640, 0) are read out, and then (479, 0), (478, 0), ... (0,
0) is read. When entering the second line (1119,
1), (1118, 1)...(640, 1), followed by (479, 1), (478, 1),...(0, 1)
) is read out. Thereafter, the data are read out sequentially in the same manner. At this time, the address preset in the address counter 9 is controlled so that the (H) side address is incremented for each line, and the address counter 9 is controlled to count down the (V) side address. All you have to do is record it.

Therefore, all the contents stored in the first and second frame memory areas 61 and 62 of the frame memory 6 and the area 64 in the frame memory 6 where horizontal characters "2" and "1" are stored are read out. The recording when the image is recorded on the recording medium is as shown in Figure 5, where "2" is recorded near the second stored image and "1" is recorded near the first stored image. ing.

Note that it is of course possible to store only characters in one direction, either vertically or horizontally, in the area 64 in the frame memory 6, and rotate them at the time of reading. Further, the image number may be recorded in an overlapping manner within the image.
