Abstract

PURPOSE:To raise operability of a key in case of repeating the same processing, by outputting an inputted code and also storing it in a storage part until a prescribed code is inputted, and outputting the code stored in the storage part when the prescribed code is inputted again. CONSTITUTION:In case when a key input is executed to a controlling circuit 31 from key switches K2-Kn by a key operation, the circuit 31 outputs a key- inputted code to the outside as a signal (a) unless there is a key input from a key switch GK, and also stores it in a storage part 2. When a code is inputted from the key switch GK, the circuit 31 sends a signal (d) to an auxiliary circuit 32 if a signal (b) inputted from the circuit 32 is in a reset state, and sets the signal (b) to a set state. Subsequently, the circuit 31 outputs the signal (a) and stores it in the storage part 2. In this way, a repeated instruction of the same key input can be executed by the key switch GK.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a key ID used as an input means for a combination screen system and the like.

[Technical background of the invention and its problems]

Various processes (e.g. A, B,
Conventionally, when inputting an instruction (C...), it is performed by operating a combination of dedicated keys or ordinary keys determined corresponding to each process. For this reason, for example
ASB, B, I3. When inputting an instruction such as B, .

[Purpose of the invention]

The present invention has been developed in view of the current situation, and its purpose is to improve the operability of keys when inputting instructions so that the same process is repeatedly performed.

[Summary of the invention]

Therefore, the present invention includes a key switch unit that outputs a code corresponding to the key when the key is operated, a storage unit that stores the code output from the key switch unit, and a memory unit that stores the code outputted from the key switch unit. When a predetermined code is input, the input code is output and stored in the storage unit, and when the predetermined code is input again, the code F stored in the storage unit is output. The above objective was achieved by configuring the controller with a control section that outputs the following.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a diagram showing the configuration of this embodiment. 1 in the figure is a key switch section. Key switch part 1 is key switch K +
, K2, . . . J (the first is made up of n and GK.

1, K on the key switch! ,..., Kn and GK each output a unique call r when pressed. 2 is a storage section. The storage section 2 is a circuit in which the code P output from the key switch section 1 is stored. 3 is a control section. The control section 3 is composed of a control circuit 31 and an auxiliary circuit 32. The control circuit 31 receives the code P from the key switch section. Then, if the input code is a predetermined code 1? A judgment is made as to whether or not. In this embodiment, the code r output from the key switch GK is a predetermined code P. The auxiliary circuit 32 outputs a set signal or a reset signal, for example, a signal of "0" or 1, and causes the control circuit 31 to determine whether the input GK call r is input for the first time or is input again. This is a circuit for

Next, the present invention will be explained in detail using the timing diagram of FIG.

First, input the reset signal C to the auxiliary circuit 32 from the outside,
The auxiliary circuit 32 is initialized and a set signal is output. (
Logic "0" is significant) Then, by key operation, the key switch is set to 1, K2, . . . , Kn to the control circuit 3.
It is assumed that the key human effort is made in 1. Control circuit 311I: ↓
When it is determined that there is no key input from the key switch GK, a signal d is output to the auxiliary circuit 32 and the storage section 2.

Therefore, the auxiliary circuit 32 changes the signal from the set state to the reset state in the second step as shown in FIG.

On the other hand, the storage section 2 clears the stored contents by the signal d.

Subsequently, the control circuit 31 outputs the manually input code P to the outside as a signal a, and stores it in the storage section 2. Thereafter, the control circuit 31 outputs the code r manually inputted from the key switch GK as a signal a until a code is inputted from the key switch GK, and stores it in the storage section 2. By the way, key switch GK
When code P is input from
is output to change the signal to the set state. That is, as shown in FIG. 2, when the signal d is input at ts, the signal S recovers from the reset state to the set state.

This indicates the end of input for one process. Then, the signal P of the switch Gi is outputted as a signal a, and as described in 1.
Stored in α section 2. After that, key switch GK to CoP
When input, the control circuit 31 outputs the codes from the storage unit 2 since the signal S is still in the set state.
are read out in the stored order and output as signal a.

In other words, it instructs to repeat the same process.

From this, the - processing is changed to a + key switch.

After inputting an instruction using a combination of K2,...,Kn, if you want to repeat the instruction input for this process, operate the key switch GK to indicate the end of instruction input, and then press only the key switch GK again. All you have to do is operate.

That is, according to the present invention, the key switches Kl, K2, . . .
, When the key switch OK indicating termination is pressed immediately after the 1st general key is pressed manually, it acts as a delimiter key, whereas when the 1st key of Ki is pressed individually or in combination, it acts as a delimiter key. This is a repeating hexagonal instruction key that instructs the transmission of the contents stored in the storage unit, that is, the automatic reproduction of the previous single key manually. Therefore, no matter how many times the same key is manually pressed, the key switch GK can be used to repeatedly instruct the key switch GK, thereby significantly improving the operability.

Signal C can be set to the set state by inputting signal C in the external system at the initial or necessary time. can be given meaning. For example,
There are times when the delimiter/key manual input is not necessary for a field where the number of key hexagonal digits is specified in advance, and in this case, input the C signal when the key input signal of the specified number of digits is obtained from the signal a. , GK input as a delimiter key becomes unnecessary.

〔Effect of the invention〕

According to the present invention, since the delimiter key (such as the Feel P/Release/Instruction key or CR key is known) also serves as a repeat instruction key, this key can be used when repeating a certain processing instruction or data input. It can be operated in a unified manner, and the operability is significantly improved.
