Abstract

PURPOSE:To supply rich error information without adding an expensive display unit by printing error information on a recording medium using own printing function when an inputting error is recognized in an XY recording device. CONSTITUTION:When the occurrence of an error is recognized, an LED (not shown in the figure) is lit up to give a warning to an operator. Then, relevant one out of plural causes of occurrence of the error is stored. When it is detected that the operator is requesting error information and depressing a key, stored error information is recorded on a recording medium using printing function possessed by the XY recoding device in a form consisting of a message and data etc. easily understadable by the operator.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an XY recording device, and in particular, means for driving a recording pen in the X-axis and Y-axis directions, and means for driving the recording pen up and down. This relates to an XY recording device that is equipped with a control means that controls these drive means according to external commands to print and draw on an XY surface recording medium, and is unrecognizable to the recording device from the outside. This is intended to enrich the content of error information that will be notified to the device operator when a command that is complex or has elements that exceed the limits is given.

[Conventional technology]

Demand for higher functionality for this type of recording apparatus is increasing year by year, and commands given to the recording apparatus from the outside are also becoming more complex. For example, the command ``-'' may include multiple elements, or restrictive conditions may be added to each element. The control section inside the device is
When such external commands are received as input, a single print is made on the recording medium by combining the commands, but at this time, commands that cannot be recognized from the outside or commands that combine elements that exceed limits may be received. If given, the equipment operator must be warned in some way. Of course, the error information that the recording device provides to the operator must have quick dissolution properties, but it is even more important that the error information has rich content.

Conventional examples of this warning means and their problems are shown in Figures 4 and 5.
This will be explained using figures. In FIG. 4, the warning means is composed of a light emitting diode and a piezoelectric buzzer.

Under normal conditions, the light emitting diode 42 is off and the piezoelectric buzzer 43 does not operate. In other words, an inappropriate command is given from the outside to the microprocessor control circuit 4 even though the command input is in a normal state.
When 1 recognizes this, it lights up the light emitting diode 42,
The piezoelectric buzzer 43 is activated to give a warning to the operator.

The conventional example shown in FIG. 4 can be realized at low cost and has excellent rapid dissolution, but has a problem in that it can only provide a single piece of information: whether or not an error has occurred.

FIG. 5 shows a conventional example configured with a liquid crystal display. In this example, the microprocessor control circuit 5■ always controls the liquid crystal display 53 via the liquid crystal display drive circuit 52.
The status of the recording device is displayed on the top, and the operator can check the status by viewing this display as a message.

According to this method shown in Figure 5, it is possible to provide a wealth of information and increase the efficiency of program development, but,
There is a problem in that an expensive liquid crystal display device must be added separately, which increases the cost of the XY recording device.

[Problem that the invention seeks to solve]

SUMMARY OF THE INVENTION An object of the present invention is to provide an XY recording device that can solve the above problems of the prior art and provide a wealth of error information at a low cost.

[Means for solving problems]

The above objective is achieved by making full use of the printing function provided by the XY recording device and printing error information given to the operator on the recording medium when it is recognized that there is an error in external command input. be done.

[Effect]

Since this method uses the printing function of the XY recording device to print error information on the recording medium, it can be realized by simply adding a small control program. It can be provided at low cost.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3. FIG. 1 is a block diagram of the control system in the embodiment, FIG. 2 is a flowchart of its control processing, and FIG. 3 shows an example of printing. In FIG. 1, commands given from the outside are taken into a microprocessor 2 via an interface control circuit 1, and are stored in a RAM (random memory).

mory) Temporarily stored in 4. Thereafter, at the stage of executing the command, the X-axis stepping motor 8, Y-axis stepping motor 9, and recording ben 10 are connected to the X-axis motor drive circuit 5, Y-axis motor drive circuit 6, and pen lifter drive circuit 7, respectively.
Printing and drawing are performed in response to command input. Here, if the microprocessor 2 detects an abnormality in the input command, the ROM (read-only)
According to the control program stored in the memory (read only memory) 3, the following operations shown in the flowchart of FIG. 2 are performed.

When the occurrence of an error is recognized in judgment process P2, process P3
Proceed to step 1, and first select LED (light emitting diode, Light).
Eivaitting Diode) lights up to warn the operator. Thereafter, information on the applicable error among the plurality of error causes is stored (process P4). As this information, information consisting of messages and data that are easy for the operator to understand is used. After this error information storage operation is completed, the command input routine of step P1 is searched again.
Continue inputting subsequent commands. In the main routine after step P5, the error occurrence status is checked in P6, and if an error has already occurred, the process advances to P1 to determine whether or not the operator is pressing a key. At this time, if the key is not pressed, the process returns to the command input routine of P1, and if it is pressed, the process moves to the error information printing routine of P8.

In the error information printing routine of P8, the already stored error information is recorded on the recording medium using the printing function of the XY recording device.

Thereafter, the error state is canceled and the process returns to the Pl command input routine. FIG. 3 shows an example of error information recorded on the recording medium 32 of the XY recording device 31.

〔Effect of the invention〕

According to the present invention, it is possible to immediately provide the latest error information with rich character content, and since the method utilizes the printing function of the recording device itself, there is no unnecessary cost. There is no upgrade and it can be realized at low cost.
