Abstract

PURPOSE:To accurately and rapidly eliminate an abnormal state even if an instruction manual of a printer is not referred by providing control means for sequentially displaying abnormal state display message on a liquid crystal display panel. CONSTITUTION:When a malfunction is detected, a microcomputer 104 analyzes it, and set a leading address of a memory for storing data of display message corresponding to generated malfunction to a display data pointer. Then, data of determined number are read from a set display data pointer, and a liquid crystal display panel 103 is initialized and displayed. It reads data of 10 characters from the pointer and displays in the lower stage of the panel 103. Then, whether the malfunction is removed or not is checked. If the malfunction is continued, the detailed explanation of the lower stage of the panel 103 and the display of a recovering method are repeatedly displayed while shifting characters one by one. If the malfunction is removed, the abnormal state display is all erased, and the display operation at the time of the malfunction is ended.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a printing device that has a function of displaying an abnormal state when various abnormalities occur, and in particular, the present invention relates to a printing device that has a function of displaying the abnormal state when various abnormalities occur. This invention relates to a printing device that enables abnormality detection and recovery without referring to an instruction manual by displaying explanatory text on a liquid crystal display panel. [Prior Art] In conventional printing devices, when various abnormalities occur, a lamp indicating the item of the abnormality is turned on, or a liquid crystal display panel simply displays only the items related to the abnormality. is adopted.

[Problem to be solved by the invention]

With the above-mentioned methods for displaying abnormal conditions in conventional printing devices, detailed information cannot be displayed due to limitations in the number of characters that can be displayed and the number of characters that can be displayed on the LCD panel. Since recovery methods cannot be displayed, it is necessary to read the instructions for the printing device and deal with them, which has the disadvantage of requiring a lot of time and effort. In addition, if there is no manual, the operator may guess the details of the error and take the wrong recovery method, resulting in the received data being discarded or having a negative impact on the printing device. be. [Means for Solving the Problems] The printing apparatus of the present invention includes an am section having a detection means for detecting an abnormality, a liquid crystal display panel for displaying a message, and a message displaying part that cannot be displayed at one time on the liquid crystal display panel. The apparatus includes a read-only memory storing an abnormal state display message composed of data, and a control means for sequentially displaying the abnormal state display message on the liquid crystal display panel. [Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In FIG. 1, a higher-level interface 101 communicates with a higher-level computer (not shown). The mechanism unit 102 performs printing operations according to print commands based on data received by the host interface 101, and includes physical abnormality detection means (sensors, etc.)
have. The liquid crystal display panel 103 displays the status of the printing apparatus. Microfun Viewer 1
04 controls the printing device. ROM (Read Only Memory') 105 is a memory that stores programs executed by the microcomputer 104.
Logical anomaly detection means (programs), liquid crystal display panel display means (programs), and display data are stored here. RAM (random access memory) 106
is a memory that stores data necessary for the operation of the microphone computer 104 (for example, data received by the upper interface 101). FIG. 2 is a plan view showing the operation panel of the printing apparatus of the embodiment shown in FIG. In FIG. 2, the liquid crystal display panel 103 is connected to the operation panel 202.
It has a 10-digit, two-level display screen. Next, the operation of this embodiment will be explained.

FIG. 3 is a flowchart showing the display operation on the liquid crystal display panel 103 when an abnormality occurs in the printing device. In FIG. 3, when an abnormality in the printing apparatus is detected, the microcomputer 104 performs a detailed analysis of the abnormality (reference numeral 1l). When the analysis is completed, the display data pointer is set to the first address of the memory that stores the data of the display message corresponding to the abnormality that has occurred (reference number 1).
2). Display message data is stored in the ROMI O5 in advance for the number of abnormalities that are expected to occur. Next, a predetermined number of data is read out from the display data pointer that has been set, and initial display is performed on the liquid crystal display panel 103 (reference numeral 13). The displayed message is divided into two stages, as shown in the liquid crystal display panel 103 in FIG. 2, with the abnormal item displayed on the upper stage and its detailed explanation and recovery method displayed on the lower stage. For initial display, the upper row is first displayed, and then the display data pointer is reset to the first address of the lower display data, and the lower row is displayed. When the initial display is completed, the operator remains in that state and waits for a time long enough for the operator to read the displayed content (reference numeral 14). Next, the display data pointer is advanced by one character (reference numeral 15). At this time, if the pointer indicates the last character of the display data, the liquid crystal display panel 10
3 to point to the first address of the display data in the lower row. Data for 10 characters is read from the updated display data pointer and displayed on the lower row of the liquid crystal display panel 103 (reference numeral 16). At this time, if data for 10 characters does not exist between the character indicated by the display data pointer and the last character, data corresponding to the number of missing characters are read out and displayed in order from the preceding data.

After this, check whether the abnormal condition has been cleared (
Reference numeral 17), if the abnormal condition continues, the detailed explanation and recovery method are repeatedly displayed on the lower part of the liquid crystal display panel 103 while shifting one character at a time. If the abnormal condition has been canceled, erase all abnormal condition displays (reference number 1).
8) End the display operation when an abnormality occurs.

FIG. 4 is a plan view showing an example of a display state of the operation shown in FIG. 3.

The data in the area 103a of the liquid crystal display panel 103 are the characters actually displayed.

The data 21 shows the initial display state, and abnormal items are displayed in the upper row of the liquid crystal display panel 103, and this part does not change thereafter. In the lower row, the first part of message data indicating a detailed explanation of the abnormal state and a recovery method is displayed. Data 22 shows the state in which the lower display has been shifted by one character. Similarly, as shown in data 23 to 25, all messages are repeatedly displayed while shifting one character at a time.

〔Effect of the invention〕

As explained above, when an abnormality occurs in the mechanical part of the printing apparatus of the present invention, a detailed explanation of the abnormality, which is made up of an amount of data that cannot be displayed at once on the liquid crystal display panel, and a recovery method are provided. By displaying all data while sequentially shifting messages, there is an effect that an abnormal state can be dealt with accurately and quickly without referring to the instruction manual of the printing device.
