Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a processing method for a repeat function of a key-input signal.

<Prior Art> In a conventional key input device, when a function of a certain key is to be operated continuously, the device is first switched to a repeat mode by pressing a repeat key that issues a continuous operation instruction. In the repeat mode, in which the repeat key is being pressed, a key input for another function that is desired to be operated continuously is awaited.

Then, in this state, when a key is pressed for continuous operation, the data code of the key is repeatedly transferred while the key is pressed, and the continuous operation is executed.

In this conventional configuration, it is necessary to simultaneously detect the repeat mode by pressing the repeat key and detect the data code by pressing other keys that you want to perform continuous operation. A repeat key detection circuit was provided separately from the code exchange circuit. As a result, the signal transmission and reception and the circuit configuration are complicated, and input operations during this repeat are also troublesome.

<Object of the Invention> The present invention is a processing method that solves the above-mentioned problems, and when a function based on a certain key input signal is operated continuously (repeat operation), this key input processing is simple, and the circuit configuration and signal exchange are simple. The present invention provides a processing method devised to simplify the processing.

<Embodiment> FIG. 1 shows a block configuration of a data processing device, and FIG. 2 shows a flowchart of the operation of the processing system of the present invention.

First, in FIG. 1, reference numeral 1 denotes a keyboard section, and if it is a character information processing device, for example, a group of data keys for inputting various character data and related data, and a group of function keys for generating control signals. A repeat key is included as one of the data keys. Furthermore, the keyboard section 1 is equipped with encoding circuits corresponding to various keys.

2 is a control unit that processes input data input from the keyboard unit 1, and includes output equipment (display device,
It is connected to a printer) 3 and a storage device 4 to control the output or storage of input data.

The control unit 2 includes a code determination circuit 21 for determining a coded signal inputted from the keyboard unit 1, and a key code that is a target of repeat operation based on the determination of the code determination circuit 21 (repeat operation is possible). key) is contained in the register Reg
It is provided with a buffer memory circuit 22 consisting of a buffer memory circuit 22 and a memory (not shown) that holds a program for executing operations as shown in FIG.

To explain this operation with reference to the flowchart in Figure 2, if there is a key input in the key input standby state A, a check is made to see if there is a key input in step _n1 , and the key input is not detected. If there is, move to step n ₂ and check whether there is a repeat key.

This is for the code determination circuit 21 of the control section 2 to determine the coded signal transferred from the keyboard section 1.

If it is determined in step _n2 that the input code is not a repeat key code, the process moves to step _n3 , where it is determined whether the input code can be subject to a repeat operation. In this case, all normal character keys etc. are keys that can perform repeat operations.

Therefore, assuming that the code is capable of repeat operation, the process moves from step _n3 to step _n4 .

In this step _n4 , after clearing the contents held in the buffer memory circuit 22 of the control section 2, the encoded signal of the input key is stored in the register Reg of the buffer memory circuit 22. Then, the process moves from step _n4 to step _n5 to execute the process based on the input key, and then enters the state A of waiting for input of the next key. Execution of the processing herein means transferring the input coded signal to the output device 3 and the storage device 4, displaying or printing it, and storing it as data.

When the repeat key is pressed here, the process progresses from step n ₁ to step n ₂ , the repeat key is changed at step n ₂ , and the process moves to step n.

In this step _n8 , it is determined whether or not the encoded signal is held in the buffer memory circuit 22.
Here, since the coded signal is held in the register Reg as described above, the process moves to step _n9 .

If the buffer memory circuit 22 does not hold the coded signal, the next key input standby state A is entered.

When moving from step n ₈ to step n ₉ ,
Since the coded signal is held in the register Reg, this coded signal is extracted and processed, and then the state A is set to wait for the next key input.

If the repeat key is still pressed here, the process proceeds again from steps n ₁ → n ₂ to n ₈ → n ₉ , and the encoded signal in the register Reg is processed again. Therefore, while the repeat key is pressed, the repeat operation of the coded signal held in the register Reg is executed.

On the other hand, if a key that is not the target of repeat operation, for example a specific function key other than a character key, is operated from the key input standby state, step n ₁ → n ₂
→n ₃ →n ₆ →n ₇ , and the buffer memory circuit 22
The coded signal held in the input key is erased, and then the processing of the input key is executed.

<Effects> As described above, in the processing method of the present invention, when performing a repeat operation of an input key, the repeat key can be operated in the normal key-in operation mode without switching between the repeat mode and the normal key-in operation mode as in the past. All you have to do is operate in the same way as the key-in operation.
There is no need to install a separate repeat key detection circuit, and the signal can be processed in the same way as a normal key signal.
The circuit configuration and signal exchange are simplified. In addition, during repeat operation, the key coded signal input to the control unit is only the repeat key code, which simplifies the processing of key-in data from the input device and further simplifies key input operations during this repeat operation. It has the following characteristics.

[Claims] 1 Repeat keys that instruct repeat operations are led to a coding circuit in the same way as the data input keys and codes are assigned to them, and it is possible to judge whether or not the repeat key input has been input and to perform repeat operations based on the coded signals corresponding to these keys. Judgment means for judging whether or not a key can be a target of a certain repeat operation, and when the judgment means detects an input of a key that is a target of a repeat operation, a coded signal of the key is temporarily held. A key input signal processing method, comprising a buffer memory circuit, and extracting a coded signal held in the buffer memory circuit based on detection of a repeat key input by the determining means and processing the coded signal.
