本発明に印字装置に関し、特に、その動作異常時におけ
る自己診断を可能としｔ印字装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device, and more particularly to a printing device that enables self-diagnosis in the event of abnormal operation.
［従来の技術］
従来、印字装置の動作異常時における装置自身の診断方
法としては、装置設計段階で予想された異常に対しての
みアラームランプの点灯やブザーの鳴動、７セグメント
表示器による異常内容の表示などの方法があった。[Prior Art] Conventionally, as a method of diagnosing the printing device itself when an abnormality occurs in its operation, only when an abnormality is predicted at the device design stage, an alarm lamp is lit, a buzzer sounds, and a 7-segment display indicates the abnormality details. There were methods such as displaying.

。Is Figure 3 the configuration of a conventional printing device? This is what is shown. In this figure, 1 is a printing circuit for actually printing, and 2 is a receiving circuit for receiving data from an external device. If an abnormality occurs in the printing device in 3.
This is an abnormal status display circuit to notify the operator.
Reference numeral 9 denotes abnormal state processing means for instructing the abnormal state display circuit 3 to display contents. 4 is a reception data storage for storing received data, and 5 is a program execution state storage for storing the execution state of a program that is processing data, both of which use RAM. ing.

字回路１が起動されて印字動作を行なう。The data received by the data receiving circuit 2 is written into the received data storage 4 by the program of the data receiving means 8.Next, the data written by the program of the data processing means 7 is analyzed, and whether it is print data or not. If so, control is passed to the program of the printing means 6. Thereafter, the printing circuit 1 is activated and performs a printing operation.
この構成における異常状態処理手段９は、プログラム設
計時にあらかじめ予想される異常動作に対してのみ有効
に働き、異常動作の種類を表示するようにできている。The abnormal state processing means 9 in this configuration operates effectively only for abnormal operations that are predicted in advance at the time of program design, and is configured to display the type of abnormal operation.
しかし予想されたもの以外の異常、例えばプログラムの

出しを行なりていた。However, it has been impossible for the printing device itself to diagnose abnormalities other than those expected, such as a program running out of control due to a bug or the received data being incorrect. Conventionally, when such an abnormal operation occurs, the printing device is temporarily stopped, an external device 16 such as an in-circuit emulator or logic analyzer for program analysis is connected, and then the abnormal operation is reproduced to analyze the program. Execution status and contents of received data are stored in the external V7cli1. This was used to determine the cause of abnormal operation.
〔発明が解決し二つとする間呟点〕

一度印字装置のｔ源を切断しなければならず、この時、
異常発生時の情報が全て消滅してしまりため、解析用装
置を接続した後で異常動作を再び発生させるという作業
が必要であった。このため発生頻度が少ない異常現象の
場合は、再現するまでに長時間を要するという問題があ
っｔ。[Two points that the invention solved] However, in the event that an unexpected program bug or abnormal operation of the printing device occurs due to an abnormality in the received data, it is necessary to diagnose the problem. External device for program analysis? The power supply of the printing device must be disconnected once to connect the wire, and at this time,
Since all information at the time of the occurrence of the abnormality is lost, it is necessary to connect the analysis device and then restart the abnormal operation. Therefore, in the case of an abnormal phenomenon that occurs infrequently, there is a problem that it takes a long time to reproduce it.
また、異常動作が発生した現場に解析用装置が設置され
ていることは少なく、その場合には印字装置か解析用装
置かのいすｎか？輸送しなければならず、解析作業が大
幅に遅れるということもあった。Furthermore, it is rare that an analysis device is installed at the site where an abnormal operation occurs, and in that case, is it a printing device or an analysis device? The data had to be transported, which sometimes caused significant delays in analysis work.
このように従来に、異常動作が発生した時点での迅速な
原因解析作業ができず、異常動作が印字装置自体の原因
によるものか、あるいは受信データの原因によるものか
の判断を早急につけられな−いという問題点がありｔ。In this way, in the past, it was not possible to quickly analyze the cause of an abnormal operation when it occurred, and it was not possible to quickly determine whether the abnormal operation was caused by the printing device itself or by the received data. -There is a problem with this.

FIG. 2 shows a flowchart of this program, and when the program is started, the contents of the program execution state memory 5 are saved 12. In addition, since the existing data processing means 7 and printing means 6 are used when printing by the self-diagnosis means, this processing is necessary to prevent the stored contents from being overwritten. After that, initialize the printing device 1
Perform step 3 to make it printable. The received data will remain in your memory without being erased. Next, the contents of the saved friend program execution state memory 5 are passed to the data processing means 7 and printed 14.
Finally, the contents of the received data storage 4 are passed to the data processing means 7, and printing 15 is performed to complete the process.
