The automatic drafting machine with the above configuration is called a paper moving plotter,
It is known.

The controller of the paper moving plotter is connected to the host computer online, moves the image line head 16 along the rails 6 based on the drawing data transferred from the host computer, and controls the rotation of the drive roller 16. Then, the pen 18 is controlled up and down to visualize the drawing data on the paper on the platen 14. The sheet placed on the platen 14 is nipped by the drive roller 16 and the pinch rollers 24, 26.

By the rotation of the drive roller 26, the paper on the platen 14 moves in the direction perpendicular to the longitudinal direction of the rail 6, that is, in the X-axis direction. At the same time, the head 16
The pen holder 20 is moved up and down along the rail 6 in the Y-axis direction, and the pen holder 20 is controlled to move up and down, so that a predetermined drawing is performed on the sheet on the platen 14. Before performing the above-mentioned drawing work, various conditions necessary for drawing, that is, parameter information is input to the controller of the plotter.

When the parameter information is input, the controller sets the parameter of the controller based on the input parameter information according to a preprogrammed parameter setting program. The operator
Parameter information corresponding to various parameters is previously written on the mark sheet 28 shown in FIG. The filling method is adopted as this entry method.

The mark sheet includes a baud rate, data length, parity bit, stop bit, sorting,
An item column 30 such as pen speed and writing pressure is described with line spacing, and to the right of each item is a numerical value, NONE, EVE.
There is a selection column 32 for conditions such as N and ODD, and the operator can select a numerical value or condition for each item by filling a desired numerical value or condition with a pen and write it in a data sheet.

Position signal for the corner 28a of the mark sheet 28 in the item column 30 of the mark sheet 28 and the selection column 3
The two white or black signals form the parameter information. When the mark sheet is automatically read, a mark sheet recognition mark 34 is written on the mark sheet as shown in FIG.

There is a read control method.

The manual control method is step 1 in FIG.
First, the mark sheet 28 that has been completed on the platen 14
Is set, and the mark sheet 28 is held between the drive roller 16 and the pinch rollers 24 and 26. Next, in step 2, the operator turns on the manual switch of the operation panel 12. As a result, the controller of the plotter starts reading the mark sheet 28 in step 3.

In the automatic control system, in FIG. 4, in step 1, the operator puts the mark sheet 28 on the platen 14
When set on, the controller starts the paper width detection operation in step 2. The paper width detection operation is as follows.
Move the mark sheet 28 back and forth on the platen 14,
The reading sensor 22 detects the X-axis position of the front edge 28b of the mark sheet 28, and then detects the Y-axis position of the right edge 28C of the mark sheet 28.

Based on these detection data, the controller recognizes the corner 28a of the mark sheet 28. Next, the controller controls the driving roller 16 and the driving device in the Y-axis direction of the head 16 in step 3, and the reading sensor 2
In step 2, the mark 34 of the mark sheet 28 is scanned, and the reading operation of the mark 34 is performed.

Next, in step 4, the controller determines whether or not the sheet is a mark sheet, and if affirmative, the controller starts reading the mark sheet 28 in step 5. When the controller makes a negative decision in step 4, it recognizes the paper set on the platen 14 as normal paper in step 6, and proceeds to the next process in step 7. The reading of the mark sheet 28 is performed according to the flowchart of FIG.

The controller starts reading the mark sheet in step 1 and shifts to the mark sheet reading mode in step 2. When switching to the mark sheet reading mode,
The controller controls the drive roller 16 and the head 16 in step 1 of FIG.
The filled-in black and white data of is read sequentially for each item column 30.

Next, the controller determines in step 2 of FIG. 6 whether a reading error has occurred. When a reading error occurs, the item having the error in step 5 of FIG. 6 is displayed on the display unit of the operation panel 12 and the error warning is displayed. The controller then proceeds to step 6 of FIG.
Then, the error item is stored in memory and the process returns to step 1 in FIG.

If a negative decision is made in step 2 of FIG. 6,
Next, the controller determines in step 3 of FIG. 6 whether or not all the reading is completed. If the determination is negative, the process returns to step 1 of FIG. 6, and if the determination is affirmative, the process proceeds to step 3 of FIG. The controller determines whether or not there is an error item in step 3 of FIG.
Move to error item correction mode of.

When the controller shifts to the error item correction mode, in step 1 of FIG. 7, all parameter items and parameter data values corresponding to their black and white data or only error items are displayed on the display section of the operation panel 12. Next, in step 2 of FIG. 7, the operator determines whether or not to manually set the parameter data value, and if affirmative, the operator operates the operation panel 12 in step 3 of FIG. Manually set the parameter data value of. If a negative decision is made in step 2 of FIG. 7, the operator selects the mark sheet 2 in step 4 of FIG.
Change 8 and start reading again.

If the controller makes a negative decision in step 3 of FIG. 5, it makes a decision in step 4 as to whether or not parameter confirmation display is to be made, and if it makes an affirmative decision, the operation panel 1
The parameter display for confirming the parameter is displayed on the second display section.

Next, the operator judges in step 6 whether or not the parameter setting is proper, and if the judgment is affirmative, the operator inputs a parameter setting signal from the operation panel 12 in step 7. As a result, the controller stores the parameter corresponding to the parameter information of the mark sheet 28, and shifts to the next operation. If the operator makes a negative decision in step 6, the operator manually sets the parameter data in step 10, and then proceeds to step 4.
