Abstract

PURPOSE:To improve the input efficiency of data and to improve the working efficiency of a data input device by adding a data input part to which the same processing as a data input part operated through a keyboard to the outside of the data input part and therefore attaining the smooth input of data. CONSTITUTION:The overall control of a system is carried out by a CPU 1 of a data input device and data are supplied to the CPU 1 from the 1st data input part 3 containing keys 3a and 3b via a signal line 4. While the input sent from the part 3 is displayed on a CRT 5 together with the data processed by the CPU 1. A memory 2 is connected to the CPU 1 and also the 2nd data input part 6 is added to a signal line 4 set between the part 3 and the CPU 1. A key 6a to which the same processing is defined as an optional key 3a of the part 3 is provided to the part 6. The key 6a is operated by an operating means like a foot, etc. different from those of keys 3a and 3b. This improves the data input efficiency as well as the working efficiency of a data input device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a data input device, and more particularly to a data input device that has an additional data input section and can smoothly input data.

[Conventional technology]

An example of a conventional data input device is shown in FIG. 3 and will be described.

In the figure, 1 is the central processing unit (central processing unit) that controls the system.
(hereinafter referred to as CPU), 2 is a main storage memory (hereinafter simply referred to as memory), 3 is a data input unit using a keyboard for inputting data to the CPU 1, 3
m, 3b are arbitrary keys of this data input section 3, 4 is a signal line for supplying data from the data input section 3 to the CPU 1, and 5 is a signal line for supplying data from this data input section 3 or the above CPU 1.
This is a display device (hereinafter referred to as a CRT) that displays the data processed in 1.

To explain the functions of each part constituting the data input device shown in FIG. 3, first, the CPU 1 controls the entire data input device and is a department that processes and executes instructions, and the memory 2 stores input data. and a department that stores processed data. Next, the data input section 3 inputs data using a keyboard, including character keys for inputting characters, 7 action keys defined for certain processing, and a shift key for switching key functions.

Any key 3m+ such as control key, mode key, etc.
, 3b, and the data input from the data input section 3 is converted into an electrical signal and sent to the CPU via the signal line 4.
1. Further, the CRT 5 is a section for displaying input data from the data input section 3 and processing results by the CPU 1.

Next, the operation of the data input device shown in FIG.
This will be explained with reference to FIG. 4, which is a chart.

First, when data is input from the data input unit 3, the CPU temporarily stores the data in the memory 2, and as shown in FIG. to judge. If it is a character string, it is displayed on the CRT 5, and if it is determined to be a command, the command is interpreted, a process corresponding to the command is executed, and the result is displayed on the CRT 5.

When inputting data from the data input section 3, character keys and function keys are used alone or in combination with shift keys, control keys, and mode keys.

[Problem that the invention seeks to solve]

In the conventional data input device as described above, since the data input section 3 is configured with keys grouped together, there is a problem in that it is inconvenient to operate two or more separated keys at the same time.

For example, the data input section 3 using the keyboard shown in FIG.
If it becomes necessary to press the key 3c at the upper right end and the key 3d at the lower left end at the same time, in this case it is impossible to press both keys 3e and 3d at the same time with one hand.

The present invention was made to solve this problem, and allows two or more keys to be easily operated at the same time.
Also, data can be entered smoothly, so
It is an object of the present invention to provide a data input device that can improve the efficiency of data input and work efficiency.

[Means for solving problems]

In the data input device according to the present invention, a second data input section defined with the same processing as the existing first data input section using the keyboard is added outside the existing first data input section using the keyboard; By operating the second data input section, it is possible to perform the same processing as when a command is given to the first data input section.

[Effect]

In the present invention, by operating the additional data input section, the same processing as when operating the corresponding existing data input section can be performed.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram showing one embodiment of a data input device according to the present invention.

In FIG. 1, the same reference numerals as in FIG. 3 indicate corresponding parts, 6 is an added data input section, and the key 6a of this additional data input section 6 is the same as the key 3a of the existing data input section 3. Processing is defined.

This additional data input section 6 is configured to add any key of the existing data input section 3 using a keyboard, and this additional data input section 6 is, for example, a foot key.

Next, the operation of the embodiment shown in FIG. 1 will be explained with reference to FIG. 2 which is a flowchart.

First, let us assume that, for example, when inputting data from the data input section 3, it is necessary to press the shift key and the character key at the same time. Then, the key 3m of the data input section 3,
If 3b is used as a shift key and a character key, respectively, step on the shift key 61 of the data input section 6 that has been added under your feet, and at the same time operate the character key 3b from the keyboard of the existing data input section 3 to input. do.

Next, data is sent to CPU 1 at the same time, and C
PU 1 temporarily stores data in memory 2, and
As shown in the figure, whether the data sent simultaneously from the existing data input section 3 and the additional data input section 6 is a character string,
Determine whether the command starts a program.

If it determines that it is a character string, it displays it on the CRT5, and if it determines that it is a command, it interprets the command, executes the process according to the command, and displays the result on the CRT5.
Displayed on 5.

In the embodiment shown in FIG. 1, a case has been described in which a shift key is added under the user's feet, but the present invention is not limited to this, and the addition of a data input section is not limited to the user's feet. Further, the keys of the data input unit to be added are not limited to the shift key, but can be applied to all keys, and the same effects as in the above embodiment can be achieved.

〔Effect of the invention〕

As explained above, according to the present invention, data can be input smoothly by adding a data input section that is defined to perform the same processing as the existing data input section outside the existing data input section using a keyboard. This has the effect of making data entry more efficient and improving work efficiency.
