Abstract

PURPOSE:To reduce the necessary capacity of a memory, by constructing such that the content of an error is printed when printing can be performed under an erroneous condition and printing the content of the error when printing can be performed under an erroneous condition being produced. CONSTITUTION:When a CPU5 detects a parity error in printing data being transferred through RS232CI/F4, CPU5 sedns a voice code of 'serial error' to a voice only CPU11. On the basis of said voice code, the voice only CPU11 takes out voice data from a dictionary ROM12 and sends them to a voice generator 13. The voice generator 13 converts said voice data to a voice which is announced through a speaker 28. In case of a printable error such as a serial transfer error, only the occurrence of an error is announced with voice and the content of the error is alarmed through printing. Consequently, the capacity of memory can be reduced considerably when compared with the case where the error is alarmed entirely with voice.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to various printer devices.

(Prior Art) In conventional printer devices, lamps or
etc., an error was displayed on the display panel -1-, but in this case, the operator could not know that an error had occurred unless he was always in a position where he could see the display panel. To improve this, a method has recently been proposed to notify error conditions using %f voice, which makes it easy to detect error conditions even if the operator is away from the device and engaged in other work as long as the voice is within the reach of the voice. I came to know about it.

(Problems to be Solved by the Invention) However, when all errors are communicated to the operator by voice as in the conventional device described above, there is a drawback that the memory capacity of the voice take increases.

In the present invention, if printing is possible in an error state that has occurred,
The present invention provides a printer device that requires less memory capacity by printing the error contents.

(Means for Solving the Problem) In order to solve the problem described in -1-, the present invention provides a printer device that can notify an error state by voice, and when printing is possible in the error state, The apparatus is provided with a configuration for printing out the error details, and also has an instruction means for selecting whether or not to print out the error details.

(Function) According to the present invention, the memory capacity can be significantly reduced compared to the conventional device that notifies all errors by voice due to the configuration described in item 1.

(Example) An example of the present invention will be described with reference to the drawings. The figure is a block diagram of a printer device connected to a host computer.

In the figure, print data from a host computer 1 is sent to a Centronics I/F (interface) 2. R
CPU consisting of 1 chip by 8232CI/F4
The data is serially transferred to the I/F port No. 5. If the print data is normal, the CPU operates the printer device based on the transferred data.

When the CPU 5 detects an error occurring in the printer unit, for example, an error caused by the ribbon end sensor 26 or the cover open switch 27, the CP tJ 5 sends audio instruction data to the audio generator 13, and outputs the audio from the speaker 2.
8, a simple sound such as a buzzer sound is generated to notify the user.

If an error occurs in the print data serially transferred from the host computer 1 to the CPU 5, for example, the R82
The print data transferred via 32CI/F4 is
When a parity error is detected by P U 5, C

+2 and sends it to the audio generator 13.
send to The audio generator 13 converts the audio data into audio, and causes the speaker 28 to generate the audio.

Even if a serial transfer error occurs, there is no problem with the printing function itself of the printer device, so in the device of the present invention,
Following the voice instruction of "serial error", CP T, J5 transfers the print content data of "parity error" to the data buffer RAM10, and prints these characters from the printer device. Furthermore, it is also possible to select whether or not to print using an instruction means such as a changeover switch.

Additionally, if the CPU 5 detects either a framing error or an overflow error, which are error contents other than a parity error that belong to a serial transfer error, the CPU 5 will similarly notify the speaker of a "serial error".
However, the printer device prints out the text "Framing error" or "1 overflow error."

In the case of a printable error such as a temporary serial transfer error, as shown in item 2 above, if you decide to notify only the error occurrence by voice and notify the contents by printout,
The memory capacity is considerably reduced compared to when all errors are notified by voice.

(Effect of the invention) Currently, it is thought that the only errors that can be printed are serial transfer errors, so the difference in memory capacity between audio and print is due to the three words that are used to express the content that should be reported for serial transfer errors. Subject to comparison. The number of spoken words and the number of printed words for the three words are as follows:

[Note: The numbers in parentheses in the print column are for pods.] Currently, the memory capacity required to represent speech-words and print-characters is generally 256 bits to 400 bits, respectively.
8 bits, so from the table in ``1'', 23 words require approximately 9 kbits (assuming 400 bits per word) for audio, and approximately 240 bits for 29 characters (as kana character expression) for print. Therefore, it is possible to reduce the memory capacity by about 8 kbit or more, and the cost can be reduced.
