Description

[Detailed Description of the Invention] [Object of the Invention] The present invention relates to a character output system in which character output is performed on a terminal device by a terminal control device controlling the terminal device in response to a message from a solid device. be.

[Prior art]

In conventional systems of this kind, the character code dot pattern (hereinafter referred to as CG) used in the terminal device
Since the amount of CG is relatively small, a method has been adopted in which these CGs are stored in a ROM, which is a non-volatile memory within the terminal device.

However, in recent years, as a result of the demand for terminal devices to output kanji, figures, etc., the amount of CG has increased dramatically, and as a result, a great deal of time and money is wasted in creating RO■. Therefore, a problem has arisen in that the system becomes extremely expensive.

Therefore, a conventional method has been adopted in which the CG is stored in the terminal control device that controls the terminal device, and the CG'Y is sent to the terminal device from the terminal control device side.

This improved conventional system includes a method in which the CG stored in the terminal control device is given to the terminal device for each character output, and a method in which the CG stored in the terminal control device is outputted.
There is a method in which all Gs are given to the terminal device in advance.

However, the former conventional system described above has the problem that the processing time of the back terminal control device is long and the amount of data given to the terminal device is large, resulting in a decrease in system processing capacity. Therefore, it is disadvantageous to use the memory of all CGi terminal devices regardless of the frequency of use, and although non-volatile memory has become larger in capacity and cheaper, it is actually necessary. There is a problem in that it is difficult to store all CGY in the terminal device.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned conventional problems,
The purpose is to provide a character ratio system that can make effective use of the CG memory provided on the terminal device side, reduce the amount of data to the terminal device, and improve processing performance. .

[Detailed description of the invention]

In order to achieve the above object, the present invention includes a terminal device that outputs characters, and a terminal control device that controls the terminal device. A group of patterns is stored in the terminal device in advance, and a dot pattern of a character code that is infrequently outputted is given to the terminal device every time a character is output, so that the terminal device can output characters using the dot pattern corresponding to the character code included in the message of the solid device. This allows frequently used characters to be made resident on the terminal device, and infrequently used CGs to be given every time and made non-resident, thereby making effective use of the terminal device's memory capacity and reducing the amount of data to the terminal device. It is characterized by the fact that the reduction is attempted.

As mentioned above, the terminal device 16 is located in the frequently used area 18.
A. Memory 1 divided into less frequently used areas 18B
The area 18A stores CGs with a high usage frequency, and the area 18B stores CGs with a low usage frequency. Then, the terminal device 16 selects a predetermined one among them according to the message 200 and sends it to the output device 200.

Here, the power-on detection signal 600 of the terminal device 16 is transmitted to the terminal device 16 via the receiver 22 in the terminal control device 14.
4Vc is supplied, and a power-on detection circuit 26 is also provided within the terminal control device 14, and its detection signal 302 is supplied to the AND gate 28.

The AND gate 28 ni is the area 1 of the spear 1 in the external storage device 12 in which the CG used in the terminal device 16 is stored.
CG is supplied from 6A, and the CG is supplied to the selection circuit 30 when the AND gate 28 is opened by the signal 302.

The selection circuit 30 selects one of the input CGs from the display device 1.
In step 6, only frequently used CGs are selected and stored in the fang 2 area 16B in the external storage device 12. The frequently used tube CG stored in the spear 2 area 16B is displayed when the AND gate 24 is opened by the detection signal 300 and the OR gate 32 is opened. The signal is sent to the terminal device 16 via the transmitter 34 and stored in the frequently used area 18A of the memory 18.

As described above, in this system, when the power is turned on to the terminal control device 14 and the terminal device 16, only frequently used CGs are stored in the CG terminal device 16 stored in the external storage device 12. The selected memory 18 in the terminal device 16

On the other hand, the message 100 output from the solid device 10 is applied to the register 56 in the terminal control device 14, and is applied to the holding register 68 on one side and the AND gate 40 on the other side. This holding register 38 can hold 104 pieces of output data in the message 100 and also includes a decoder, and the decoder detects that the DA 102 of the message 100 is addressed to the terminal device 16 and converts the AND gate 40. The output data 104 is provided to the discrimination circuit 42.

” The two-note discrimination circuit 42 detects the CG corresponding to the output data 104.

Then, the holding register 46 sequentially gives these CGs (2 or game) 32. to the terminal device via the transmitter 4 and stores them in the less frequently used area 18B.Then, each time each CG is output, the counter is The value decreases and finally reaches 0.Then, the holding register 46 opens the previously closed gate 44Y, and outputs the output data 104 to the terminal device 16 via the AND gate 44. Areas 18B to C
Gv is read out sequentially.

The CG read out in this manner is applied to the output device 20 to output characters.

A preferred embodiment of the present invention has the above configuration, and its operation will be explained below.

When the terminal control device 14 and the terminal device 16 are powered on, frequently used CGs are read into the terminal control device 14 from the external storage device 12, and these CGs are transferred to the terminal device 16.
The data is read and held in the fang 1 area 18A of the memory 18 within the memory 18.

Thereafter, when the message 100 is given from the solid device 10, the determination circuit 42 generates a CG image corresponding to the output data.
It is determined whether or not is stored in area 18.

If it is determined by the above determination that the CG corresponding to the output data 104 is stored in the area 18, the output data 104 is given to the terminal device 16, the CG is read out from the area 18A, and this is output. The signal is applied to device 20 for character output.

Further, if it is determined that the CG corresponding to the output data 104Vc is not stored in the area 18A, the CG corresponding to the output data 104 is stored in the external storage device 12.
．． The CGs are read from the memory 48 into the terminal control device 14 and given to the terminal device 16, and the terminal device 16 stores these less frequently used CGs in the area 18B. When the storage is performed, the terminal device 16 reads out the less frequently used CGv based on the output data 104 and supplies it to the output device 20 to output characters.

As described above, according to this embodiment, it is only necessary to store frequently used CGs in the memory 18 of the terminal device 16, so that the limited capacity of the memory 18 can be used effectively. In addition, since the CG that is used infrequently is only sent to the terminal device 16 when necessary, the amount of data sent from the terminal control device 14 to the terminal control device 16 can be reduced, thereby improving system processing capacity. It is possible to do so.
