A control code containing VHC is sent. 201 to 20
7 constitutes a component of the print control unit 200, and 201
is a character code buffer section (20) that stores the character code CC sent from the processing device 100 and its accompanying control code in a predetermined unit, for example, a code string of one line.
2 is a dart circuit that distributes the character code cc and control code when reading the character code buffer section 20; 203 is a character code cc that has passed through the dart circuit 202;
This is a character generator that sequentially converts character pattern data CP into character pattern data CP in units of a predetermined dot matrix (here, 24×24 dots). 204 is 24X2 generated from the character generator 203
The 4-dot character pattern data CP is sent to the above dart circuit 2.
This is a gate circuit that performs distribution based on the contents of the VH conversion control signal VHC included in the control code output from 02. , outputs character/turn data CP to output terminal A, and outputs character pattern data CP to output terminal B when VHC=''l#, which indicates whether or not vertical/horizontal conversion of characters or turns is performed. 205 is a V-H which receives the character/turn data CP output from the output terminal B of the dart circuit 203 and converts this pattern vertically and horizontally.
This is a convergence circuit, which has a 24x24 dot four-turn memory, and converts the character pattern vertically and horizontally by changing the row and column direction during writing and reading. 206 logically ORs the character pattern data CP output from the output terminal A of the dart circuit 204 and the vertically and horizontally converted character/turn data output from the VH compurge circuit 205 on the same signal line. A dart circuit is used for outputting the data, and 207 is a line buffer section that stores the 9-turn data of the character that has passed through the dart circuit 206 at one-line intervals and sends it to the printing section 300.

Here, the operation of the embodiment will be explained with reference to FIGS. 2 to 4. During bar graph printing processing, the processing device 100 processes data for each item based on a predetermined processing program for each item, and sends the processed data, that is, the character code string to be printed, to the print control unit 200 along with the control code. Send. At this time, for each character including the item in the graph, a control code is set with the character code ()1'cc each K and VH conversion control signal VHC as "l"(VHC-"1"). will be added. In the print control unit 200, the character code string and control code sent from the processing device 100 are stored in the character code buffer 201, and once the character code string for one line is stored, it is read out in the order of input. This character code buffer section 2
The data read out from 01 is divided by the gate circuit 202 into a character code cc and a control code including a VH conversion control signal VHC'. The character code CC is then sent to the character generator 203 to generate character f-turn data CP in units of 24x24 dots according to the code contents, and the VH conversion control signal VHC is sent to the r-) circuit 204 to generate dart data. Used for switching control of output terminals A and B.

Here, if VHC='''0#, the character i9 turn data CP generated by the character generator 203
is outputted from the output terminal A of the dart circuit 204, and is sent to the line buffer section 20 via the dart circuit 206 in that state.
However, when VHC=''1#, the character 4 turn data CP generated by the character generator 203 is sent to the VH compurge 1 f circuit 205 via the output terminal B'z of the dart circuit 204. After being sent and converted horizontally and vertically,
It is sent to the line buffer section 207 via the dirt circuit 206. When one line of print data is stored in this line buffer section 207, this print data is transferred to the print section SO.
The data is sent to O and printed out line by line.

In this way, the data processed item by item is outputted by the print control unit 200. After being turned into a pattern and selectively converted into vertical and horizontal directions, it is sent to the printing section 300 and printed out.

An example of vertical/horizontal conversion of the character pattern at this time is shown in FIG. 3, and an example of the printed output is shown in FIG.

By the bar graph printing process as described above, the processing device 1
00 can perform data processing related to bar graph creation on an item-by-item basis, so even if the number of items increases, it is only necessary to repeatedly use the processing program on an item-by-item basis, which greatly simplifies the program for bar graph processing. , processing can be done easily and quickly.
