Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data processing device, and more particularly to a data processing device that displays operator guidance for key input and key input data in the same column.

In response to the conventional operator guidance display,
In so-called interactive operations where data is input, if the input method has a pre-input buffer that stores data corresponding to guidance, the input data will not be synchronized with the operator guidance for key input, and the input data will not be synchronized with the operator guidance. Since the display field and the guidance display field are displayed separately, it has the disadvantage that it is not possible to focus on only one field during input. Furthermore, the system in which the input data display field and the guidance display field are combined into one field has the disadvantage that it becomes an input device in which advance input is difficult, making it difficult to use.

The present invention provides a data processing device that improves the above-mentioned drawbacks.

Another object of the present invention is to enable full-time operators who input data by blind touch while looking at only the original paper slips one after another, and amateur operators who input data while looking at input guidance and sequentially checking input data. To provide a data processing device that is most easy to use for any operator, including an intermediate operator who has become somewhat familiar with operations but sometimes needs to confirm input data.

In other words, we provide full-time blind touch operators with a function that allows them to input data without slowing down their input speed using the advanced input function, and allows them to operate without displaying out-of-sync input guidance to avoid confusion regarding operation. General operators are provided with a function that allows them to view operator guidance and input data in the same column and input data while referring to the input guidance sequentially. To provide a data processing device having a function that allows confirmation of inputted data at a minimum by looking at one point.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention. KB is a keyboard, which has a data input key N and an entry key ENT for inputting data end, sends key data through a signal line KD, and sends an input strobe signal through a signal line SL.

The CPU is connected to a bidirectional data transfer line DATAL and a command transfer line CMNDL in order to receive key input data and send guidance data in the arithmetic unit. SR1 and SR2 are shift registers, and shift register SR1 is a key buffer.
SR2 is a shift register for guidance,
Guidance data is selected by the command transmission line CMNDL from the arithmetic unit CPU and set by the data transfer line DATAL. Disp is a display device. Shift register SR2 is merged with shift register SR1 and displayed under the condition that the guidance set command and input command have been issued and the ENTRY key ENT (indicating the data end of the input item) has not been input. FF1, FF2, FF3, and FF4 are flip-flops. Flip-flop FF1 is set by the guidance set command GS from the arithmetic unit CPU and reset by the end of input data transfer TE, and flip-flop FF2 is set by the input data transfer command TC from the arithmetic unit CPU. It is set by the end of input data transfer TE. Flip-flop FF3 is set when the entry code detection circuit DET1 detects the ENTRY code in the shift register SR1, and is reset by the input data transfer DT.

Flip-flop FF4 is shift register SR1
It is set when the ENTRY code is detected in the shift register SR1 and the data head in the shift register SR1 is detected by the data head detection circuit DET2, and the end of data transfer is detected by the ENTRY code detection circuit DET3.
It is reset when detected by. MP1, MP
2 is a multiplexer;
MP1 is for storing data from key input to shift register SR1, and multiplexer MP
2 is a shift register SR for the output to the display device Disp
This is a multiplexer for selecting based on the contents of SR1 and SR2. G1, G2, and G3 are gate circuits, and gate G1 is a gate that controls the start of data by the data head detection circuit DET2 in the shift register SR1 and the flip-flop FF4 by the ENTRY code detection circuit DET1.
2 controls the data of the shift register SR1 and the data transfer line, and controls the output of input data. Gate G3 is a gate for controlling display and controls multiplexer MP2. The inputs for control are the output of flip-flop FF1 indicating that guidance has been set by the CPU in shift register SR2, the output indicating that valid data in shift register SR2 has been detected by valid data detection circuit DET4, and the output in shift register SR1. The output that the ENTRY code is not detected, the output that the CPU has issued an input data transfer instruction for shift register SR1, and the multiplexer
This is a gate to control SR2.

Therefore, the display device Disp is multiplexer SR2
Guidance is set in shift register SR2 by gate G3 from the arithmetic unit CPU, and there is valid data in shift register SR2, and input data has not been sent yet, and an input data transfer command for shift register SR1 is issued from the arithmetic unit CPU. Shift register SR only under the condition that
Displays the contents of 2, and at other times shifts register SR1
Display the contents of. The operation of the embodiment will be explained below using display examples. Figure 2 shows the state in the middle of data input, where a shows the contents of shift register SR1, and □E shows the contents of shift register SR1.
ENTRY key ENT indicates the entry code and identifies input data.

b indicates the contents of the shift register SR2, and the contents are guidance for "123" of the shift register SR1. Shift register SR1 contains data "100" after the entry code, but this is data for the next guidance and indicates the state when the operator knows what the next input data is. The input indicates an incomplete state.

In the above state, since the entry code "E" has already been input, the detection of the entry code "E" is performed by the ENTRY code detection circuit DET.
1, flip-flop FF3 is set, gate G3 is closed, and shift register SR
1 is sent to the display device Disp and displayed as shown in FIG. 2c.

This is because the operator is immediately set to the next item, so displaying guidance that is out of synchronization with input is prohibited.

"123" by data head search circuit DET2
When the head of the flip-flop is detected, the flip-flop FF
The detection signal sets the flip-flop FF4 through the gate G1 which is opened by the Q output of 3, and the flip-flop FF3 is reset by the output of the flip-flop FF4, and the contents of the shift register SR1 are transferred to the signal line DATAL through the gate G2.
is sent to the arithmetic unit CPU via. When "123" is sent and then "E" passes through the gate G2, the entry code "E" is detected by the ENTRY code detection circuit DET3, and the flip-flop FF4 is detected.
is reset, gate G2 is closed, and data transfer is terminated. Also, flip-flop FF1, FF
2 is reset. "123E" of shift register SR1 is cleared by the output Q of flip-flop FF4. Therefore, the output of flip-flop FF2 inhibits AND gate G3 and displays the contents of shift register SR1. FIG. 3 shows the above state. The above data is sent to the arithmetic unit CPU, and the code of "E" in the data "123E" is determined,
The end of the data is determined, the arithmetic unit CPU processes the data, and sends out the next guidance. The arithmetic unit CPU stores the above-mentioned guidance in the shift register SR2 by a guidance set command of 〓〓〓SURRY〓NEW RYOK〓--4--4-, and the flip-flop FF2 is set by an input data transfer command TC. Since the entry code "E" is not currently in the shift register SR1, the opening of the gate G3 is determined by the output of the character valid data detection circuit DET4, and the blank code "x" in the shift register SR2 is detected. When this happens, multiplexer MP2 selects shift register SR1, and otherwise selects shift register SR1.

Therefore, as shown in Figure 4, shift registers SR1 and SR
2 is displayed. This state is equivalent to a case where an operator who is not familiar with general operations sequentially inputs data while referring to input guidance.
Since it is configured as described above, the shift register
Input more data to SR1 and shift register
The display of the contents of SR1 is partially suppressed by the action of multiplexer MP2.

For example, as shown in Figure 5, the shift register SR
1. When data is stored in SR2, it is displayed as shown in c of FIG.

As explained above, according to the present invention, there is no need to display troublesome guidance for full-time operators who are accustomed to input operations, and conversely, there is no need to display troublesome guidance for full-time operators who are accustomed to input operations. When there is no data to be processed in the advance input buffer, guidance is displayed so that the operator can operate while understanding the contents of the data to be input.
