Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information recording method for effectively recording barcodes on a recording medium such as a tape.

When various types of information are coded and recorded as bit information, magnetic recording or perforated tape is usually used.

However, magnetic recording requires a special magnetic recording and reproducing device, and the recording status cannot be confirmed visually, and perforation requires a special mechanical recording and reproducing mechanism. Moreover, a large amount of perforation waste is generated during recording, and it is difficult to downsize the recording medium.

Therefore, for example, even if a small card is attached to a product and coded information is recorded on the card to manage the product, a special recording/playback device as described above is required, and the recorded state can be visually checked. It is difficult to put into practical use something that is not reliable or difficult to cyclize.

As a means to improve such drawbacks, it is conceivable to write information in the form of a bar code that can be visually confirmed on a recording medium such as a tape, and to read this information optically.

In other words, a barcode consisting of one character and several pits on a recording medium is optically scanned and read.
To record such barcodes, it is necessary to record the spacing positions of the barcodes, etc., so this is done by printing.

For this reason, a recording device with a complicated configuration is required, and the device must also be large in size.

That is, it cannot be constructed in a compact size so that it can be freely carried.

The present invention improves the above-mentioned drawbacks, makes the mechanism sufficiently simple and compact, and not only makes it possible to effectively configure it for portable use, but also enables accurate bit spacing for the recording medium. The present invention aims to provide an information recording method that allows accurate information to be recorded by recording barcodes.

An embodiment of the present invention will be described below with reference to the drawings.

In this invention, a thermal head 11 is used as an information recording head, and this head 11 is constructed by arranging heat-generating recording chips in rows and columns in the X and X directions, and is not a monolithic type. There is a thin film method.In the monolithic method, heat is generated at the junction of the transistor, and in the thin film method, heat is generated by the resistor R of each chip as shown in Figure 1, and the heat is recorded on the thermal recording medium that is in contact with it. It is something.

In FIG. 1, a recording signal current is coupled to each of the resistors R arranged in the X and X directions through a transistor Tr.

A plurality of signal lines in the X direction and in the A recording current is caused to flow through a resistor R corresponding to a transistor Tr given by .

For example, if a signal is applied to all the y signal lines and a signal is applied to one of the X signal lines, a bar of "1" will be recorded in the X column to which this signal is applied.

FIG. 2 shows the configuration of a recording device using the thermal head 11 as described above. The input device 12 is composed of, for example, a normal keyboard, and information obtained by this input device 12 is supplied to an encoder 13. and converted into coded bit information.

The information encoded by this encoder 13 is supplied to and stored in a buffer circuit 14, and the code information stored in this buffer circuit 14 is coupled to a graphic generation circuit 15.

This figure generation circuit 15 is controlled to read out rows or columns of figures divided into a matrix in accordance with the count of a counter 16, and the counter 16 is started when information is taken out from the encoder 13. , are counted and driven with appropriate clock pulses.

For example, if the graphic matrix of the above information is mXn and n columns are specified sequentially, the maximum count value is set to n+1, and printing ends when the count value reaches n, and when counting n + 1, the maximum count value is set to n+1. A paper feed command is issued via an amplifier 17 to a holding and feeding mechanism for a recording medium (not shown), such as a tape-shaped thermal recording paper.

That is, as the count of the counter 16 advances, the graphic generation circuit 15 whose reading is controlled reads out the information of rIJ and rOJ of the row corresponding to each column as shown in FIG. This signal is generated as a Y signal from the thermal head 11, and this signal is coupled to the thermal head 11 via a driver 18 as an X direction signal.

Still, the count value signal of the counter 16 is also coupled to the thermal head 11 via the driver 19 as an X direction signal.

That is, in the recording apparatus as described above, when information is obtained from the input device 12, this information is coupled to the graphic generation circuit 15 to select a character, and at the same time the counter 16 starts counting.

Then, as the counter 16 counts, bar codes are sequentially recorded on the recording paper by specifying columns or rows in the thermal heads 11 arranged in recording chip rows and columns.

After one character is recorded, the counter 16
The output from the printer sends the recording paper to the next recording position.

Therefore, according to this device, character barcodes can be recorded with the recording paper and the recording head stationary, so recording is performed with very accurate bit intervals, and it can be used effectively. This provides an information recording medium that can be used.

FIG. 3 shows the state of the obtained information recording medium, in which barcode A is recorded by the thermal head.

In this case, if a character recording head is installed parallel to a barcode recording head, character B can be obtained for barcode A, and the recorded information can be known visually as well. , optical reading, electronic computer processing, etc. can also be effectively performed.

As described above, according to the present invention, a barcode recording device can be configured with a thermal head that operates statically, and it is easy to record the barcode and the corresponding characters at the same time. Not only can various types of information be recorded effectively, but barcodes themselves can also be recorded with great accuracy.

Especially extremely compact 1. Since it is easy to make it portable, it can also be effectively used for card-type item management or as a memo typewriter, and its effectiveness as a means of recording information is remarkable. It is.

According to such means, for example, it takes about 20 m5ec to draw a 1-bit vertical line, which is extremely effective for high-speed recording.
