Abstract

PURPOSE:To enable instantaneous reading of data by providing a data memory storing data to be printed beforehand and a data processor processing the print data of each line after inverting the upper and lower parts of characters and outputting a printing signal to a printer. CONSTITUTION:For instance, when 162 is to be printed, numerical data is stored in RAM 15 so that printing starts with 2 and ends with 1, and a single line of printing data is stored in RAM 15 again after inversion of the upper and lower rows of characters. Then printing data from RAM 15 is read into CPU 14 at each timing signal. Each heater is energized based on a printing signal from CPU 14 and the surface of printing paper 5 is printed so that the lower part of printed characters is set toward a feed-out direction, when printing paper 5 is fed downward from a printer. Thus it is made possible to identify data without adding a device to enable easy reading of the data.

Temperature data is stored in a predetermined address of 151 at any time. On the other hand, the timer circuit ■ connected to the CPU (141) continues to count while the CPU (141) is processing, and when it counts up and outputs an interrupt signal to the CPU (14), the CPU Q41 outputs a motor drive signal, and this signal is converted through I10α3 and the sub-driver circuit (1B) and given to the printer motor α9. Then, the printer motor (I&'! operates, and the printer head (3) starts printing first. If it is not at the starting position, move the printer head (3) to this position.

When the printer head (3) returns to the initial position, a return signal (2]) is sent from the mechanical section (IA) of the printer to l10 (
After that, the timing signal (C) is output from the mechanism section (IA) to the printer motor 1 by the rotation of the printer motor α.
The printer head (3) moves slightly with each timing signal. The following operation is performed while the timing signal (c) is sent to I10αy twice.

When the CPU (14) inputs a return signal via I10α3, the CPU (141) reads the temperature data stored in the RAM (151) and prints the temperature data for one line character by character. R so that it is reversed

Then, the printer head (3) is operated by the output from this main driver circuit (L) to perform printing. From then on, each time a timing signal is output, the printer head (3) moves slightly to the left and the CPU ( 14
) Printing is performed in response to a signal from the printer, and first a numerical value is printed on the right side of the printing paper, then a bar graph is printed, and one line is printed. Thereafter, printing is performed in the same manner as described above based on the temperature data stored in the RAMQS at predetermined time intervals, and the printing paper is gradually fed downward.

Here, the temperature data when the timer circuit (2) outputs the interrupt signal is, for example, when the constant temperature oven (2) is being heated.

When the temperature is 82° C., the printer head (3) moves to the position where it starts printing for the first time, and the operation below the busy period is performed while the timing signal is outputted twice from the mechanical section (IA). Note that the timer circuit (2) is reset and starts counting from 0 when the interrupt signal is output. First, CPU (1

After that, when one character is to be printed, for example, with 7 vertical dots and 5 horizontal dots, the CPU (14) prints 7 dots in 1 vertical column of 2 into 5 horizontal columns, that is, 5 dots. The top and bottom are sequentially switched based on the character data stored in the ROM (16) one column at a time.
When the dot is completed, the vertical swapping of one character is completed.

Then, similarly to 2, 8 is sequentially switched upside down based on the character data stored in ROMσIK,
The print data for the bar graph display is then processed by the CPU (14)K so that it is simply turned upside down, and is stored in the RAM αf9 after the print data of the numerical value of 82.

The above data processing is carried out while the mechanical unit (IA) outputs the first and second timing signals (Tt) and (Tt), and during this period, the printer head (
In step 3), when the above-mentioned one-dot printing is performed twice, the paper moves to the left and a space is formed at the right end of the printing paper (5). Then, when the third timing signal (T,) is output from the mechanism section (IA), this timing signal is given to the CPUfi4 via l10Q3, and the CPU

Next, when the fourth timing signal (T4) is output, the printer head (3) moves to the left by one printing line as shown by the arrow Cl51 in FIGS. 3 and 5, and the CPU ( 141 reads and outputs the signal for printing the second column from the right end of 2 from the RAM (2), and outputs it from the main driver αη to the first, fourth and WIJ7.
Heaters (4A), (4D), and (4G) are energized to print on print paper. Thereafter, every time the fifth to seventh timing signals are output, the KRAMQ51 outputs a signal corresponding to each timing, and 2 is printed by printing 5 dots, that is, 5 lines.

After the printing of No. 2 is completed, the 8th to 10th timing signals (T,) to (T+.) are sent to the busy printer head (3

The CPU (14) reads the print signal for printing the rightmost vertical column of 8 from the RAMQS, and
The print signal output of 14) is sent to the main driver α? via l10C13). ) given K, main drino < (
1? ) to the second, third, fifth and sixth heaters (4B),
(4C), (4E), and (4F)K are energized, and the printing paper changes color due to the heat generated by each heater, and printing is performed. Next, when the 12th timing signal (T1) is output, the printer head (3) moves slightly by one printing column, and then prints the second column from the right end of the CPU (141HRA MQ51 color 8). The timing signal is read and outputted, and the main driver (1st, 4th, and 7th heaters (4 people), (4D), and (4G) are energized and printed on print paper. Each time the
A print signal for printing 8 is output, and 8 is printed.

The right tip of the first bar graph (to) is printed on the print paper. After that, C every time the timing signal is output.
PU (14) is RAMQ! A signal corresponding to the first bar graph (to) is read and output from 19, and the main dryer outputs it to the second and fifth heaters (4B) and (4E), and print paper (5). Then, a portion of the first bar graph (to) is printed with the inside of the bar blanked out as shown in FIGS. 3 and 5. Then, when the printing up to the 0°C position of the first scale (to) is completed and the printing of one line of data is completed, the CPU (1

When the printer head (3) moves to the left end of the print paper (5), the printer head (3) moves to the print start position at the right end of the print paper (5) by the operation of the printer sweater (9). 5) is sent downward by a predetermined length as shown by arrow 061 in FIGS. 3 and 5.

Note that the first scale (to) and the second scale surface are printed every 10 times, for example, when temperature data is printed.

Thereafter, when the timer circuit (a) counts up after a predetermined period of time has elapsed, if the temperature data stored in the RAM (L!9) is, for example, 94°C, this temperature data of 94°C is read into the CPU (141). , based on the program stored in the ROMQ61 in the same way as when printing 82°C, the printing order of 94 is changed to 5 so that 4 is printed first, 9 is printed next, and RAM α
Further, printing of the right tip of the bar graph is started from position 94 of the first scale (c), and the bar graph is displayed.

Based on the character data stored in advance in the ROM, the upper and lower sides of the 40 character data are swapped one vertical column at a time for 5 columns, that is, 5 dots. Based on the character data stored in the ROM (161), the top and bottom are sequentially switched and stored in the KRAM (15) in the same way. Also, the print data for the bar graph display at 94°C is simply summed so that the top and bottom are reversed. Processed and stored in RAMQ!19.

When the mechanical section (IA) outputs a timing signal after the above processing is completed and a margin is formed on the right edge of the print paper (5), the IC, CPU ( 14) reads one line of print data stored in advance from the RAM (I51) one column at a time from the right end every time a timing signal is output, and energizes a predetermined heater as the printer head (3) moves. Print from the right edge to the left.

When the printing of 94 is completed, the main driver (171) does not output at all, and no printing is performed and a margin is formed until the printer head (3) moves to the 94°C position on the first scale of 0 to 100°C. Then, when a predetermined timing signal is output and the printer head (3) moves to the first scale (to) position of 94°C, the CPU 14) reads the second bar graph r31 from the RAM α9.

3) moves, the second and fifth heaters (4B),
(4E) is energized, and a part of the second part graph G1) is printed on the printing paper (5) with the inside whitened out.

After the printing of the first scale (E) up to 0°C and the printing of one line of data at 94°C is completed, the printer head (3) moves to the left every time the timing signal is output. No printing is done and the printer head (3
) moves to the left end of the print paper, the printer head (3) presses the right end of the print paper (5), and the print paper (5) is sent downward by a predetermined length.

From then on, every K when the timer circuit ■ counts up.

At that time, the temperature data stored in the RAM (151) is processed in the same manner as described above, printed on printing paper (5), and numerical values and bar graphs are displayed simultaneously.

When the timer circuit counts up and outputs an interrupt signal, when the temperature data stored in RAMa5IK is 162°C, the CPU (
In L4, 162 is changed to 2.6.1 Jl
Corresponding to the second scale @ from 100℃ to 200℃,
Printing of the third bar graph (to) is started from the position of 162° C. One line of 5IC print data is processed and stored in RAMQS. Then, based on the character data of the ROM (lie), the top and bottom of each of the 162 characters are sequentially switched and stored in the RAM (1!9).
The bar graph display of °C is also processed in the same way as uAM (

A third bar graph G2 is printed by the second printing method in which the inside indicating the temperature is also printed, and the print paper (5) is sent out after the printer head (3) moves to the left end.

Also, when the timer circuit outputs an interrupt signal after a predetermined period of time has elapsed and the temperature data stored in RAM α9 is 160°C, the CPU α! At step 9, the temperature data is processed and one line of print data is stored in RAM (1
! 19 is stored. Then, based on this print data, the numerical value 160 is printed on the printing paper (5) in the same way as in the case of 162°C. Then, from the 160°C position of the second scale (capital), turn on the second to fifth heaters (4B).
~ (4E) is output, printing of the 4th bar graph (to) is started, and the 4th bar graph (c) representing 160 degrees Celsius, which is also printed inside 1, is printed in the same way as the above bar graph of 162 degrees Celsius is printed. After the printer head (3) stops moving, the print paper (5) is sent out.

From then on, every time a timing signal is output from the timer circuit, the temperature is printed out as a numerical value and a bar graph based on the temperature data stored in the RAMQS.
When printing bar graphs, temperature data ranges from 0℃ to
When the temperature is 100℃, K is displayed as a bar graph with a blank space inside the bar graph corresponding to the first scale (to), and when the temperature data is between 100℃ and 200℃, K is displayed on the second scale (5). ), a bar graph is displayed in which the inside of the bar graph is also printed. In addition, the arrow in Figure 3 (

In particular, when searching for data at a predetermined time from the sent print paper, it is sufficient to check the print data in the proper orientation on the surface of the print paper (5), and the confirmation work can be done in a short time.

In the above embodiment, the explanation was based on an example in which the temperature data of the thermostatic chamber (1) is printed and displayed as numerical values and a bar graph. However, when the temperature data is printed and displayed as numerical values only, Even when printing and displaying multiple temperature data, one line of temperature data is stored in the RAM (is), the print head is replaced in the CPU (141), and then the character data stored in the ROMQ61 is The top and bottom of the characters are swapped, and instead of printing from right to left on the print paper (5), it is possible to print with the bottom of the characters facing in the feeding direction of the print paper, similar to the above embodiment, and similar to the above embodiment.
