Abstract

PURPOSE:To switch input devices in a short time without malfunction by stopping data transmission for a specific time once indication data on input device switching is inputted, and sending out a command for outputting a response signal for deciding an input device. CONSTITUTION:When the key 4 corresponding to No.4 in a menu display is operated, a main control circuit 5 holds a state in which data is not transmitted to an input device 3. Then, a timer is set. Another input device is connected before the timer finishes clocking. The command which outputs the response signal for deciding on the newly connected input device is sent from the main control circuit 5 to the input device after the clocking is completed. Thus, the decision on the input device is made and then the main control circuit 5 performs system operation processing. Consequently, the input devices are switched in a short time without malfunction.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an information processing device that can switch between a plurality of input devices. The present invention relates to an information processing device that can easily perform processing without any problems.

[Background of the invention]

FIG. 1 shows the general configuration of this type of information processing device. In the figure, 1 indicates the main body, and the main body 1
A CRT 2 for displaying processing status and a flexible disk device 4 for driving a flexible medium (not shown, hereinafter referred to as floppy) as a storage medium are stored in the .

Furthermore, an input device 3 is arranged at the front of the main body 1, allowing the operator to input characters and the like.

FIG. 2 shows a schematic configuration of the information processing device, and in the same figure, the main control circuit 5 and the cables 6.
7.8 indicates that it is connected.

A specific configuration of the main control circuit 5 shown in FIG. 2 is shown in FIG.

In the figure, 10 is a program storage type calculation unit (hereinafter referred to as COU), and 11 is a boot RO comprising a non-volatile memory and having a program executed when the power is turned on.
M, 12 is a program memory for storing a program that performs the function of a document editing device; 14 is a character generator that stores dot data representing kanji characters in a dot matrix as an index of kanji codes; 15;
is a controller that reads dot data from the character generator 14 and generates a signal for operating the CRT 2 in accordance with the command of C0UIO.

13 controls the flexible disk device 4;

This is a flexible disk control circuit (FDC).

The above-mentioned circuit sections are connected to each other by a pass line 20.

In the above configuration, when the power is turned on, the CPU 10
A program stored in the boot ROM 11, which is an initial program loader, is executed.

Generally, such a program transfers data stored on a floppy disk (not shown) set in the flexi-pull disk device 4 to the program memory 12.

When this transfer is completed, the CPU 10 branches control to the starting address of the program stored in the program memory 12 that functions as a document editing device.

As a result, it becomes possible to perform processes such as displaying characters on the CRT 2 and editing documents according to the manual operation keys on the input device 3 via the manual keys CE16 and CPU10.

Let us consider an input device in such a device configuration. The input device 3 is of a keyboard type, and the input device 21 shown in FIG. 4 is called a tablet, and is generally called a flat keyboard. The structure consists of a pattern on a substrate as a contact point, and a 0.000.
It has a gap of about 2 mm, and conductive voltage mats and character sheets are placed there. In terms of actual keystrokes, when the character sheet is pressed, the conductive voltage mat deforms and short-circuits the contact pattern on the board, and the contact has a one-make structure.

These input devices are detachable from the main body 1 using plugs 22.

Generally, when using the processing device, there is a possibility that an unspecified number of people will operate it, and preferences as an input device will naturally arise. The ease of input varies from person to person, and it is not preferable to fix it to a specific input device because it will lead to a decrease in input efficiency.

Further, there is a problem in that arbitrarily attaching or detaching the input device to the information processing device while the input device is energized may lead to errors if signals are being sent or received.

Furthermore, in order to switch input devices, it is possible to turn off the power and then attach a new input device, but this method requires time to load a new program, which reduces operability. There's a problem.

[Purpose of the invention]

An object of the present invention is to provide an information processing apparatus that can reliably switch an input device to another input device during a processing operation in a short period of time without malfunctioning.

[Summary of the invention]

The present invention provides an information processing apparatus that is electrically connected to an input device that inputs data and processes the input data, and when data instructing input device switching is input from the currently connected input device, the input device It is characterized by stopping the transmission of data to the input device for a predetermined period of time, and then sending a command to the newly connected input device to stop outputting a response signal for identifying the input device.

[Embodiments of the invention]

An embodiment of the present invention will be described based on FIGS. 5 to 7.

5 and 6 show the contents of the program executed by the CPU10 in FIG. 3, and in the same figure, when the power is turned on, the hardware is Checks are performed. This is to check whether the function of the program memory 12 is normal or not, and the specific code oo
.

FFetc is written, read and compared.

The completion of the check is confirmed in step 31. If the check is completed, the system is loaded from the floppy in step 32, and the completion of the operation is confirmed in step 33. Then, in step 34, the connected input device is determined, and the keyboard of input device 3 or input device 2 is selected.
Check if it is a flat keychain (No. 1).

Furthermore, a menu is displayed in step 35.

An example of the menu is shown in FIG. Then, in step 36, the content of the key human power is determined. When the key 412 II is input, the document is loaded from the document floppy disk in step 37, and the system operation process is executed in the next step 39.

In step 39, system operation processing is performed.

When the key "3" in step 36 is input, another auxiliary function is loaded from the system floppy in step 38, and then the system operation process is performed in step 39.

Furthermore, when the key "4" is input in step 36, the main control circuit 5 maintains a state in which no data is transmitted to the input device 3. Then, in step 4o, a timer is set, and in step 41, it is checked whether or not the timer has finished counting. For example, 5 seconds is set as this time. During the time measurement, another input device is attached. After the time measurement is completed, in step 42, in order to determine the newly connected input device, the main control circuit 5 side sends a command to the input device to output a response signal for determining the input device. . After determining the input device in this manner, system operation processing is performed in step 39.

Next, FIG. 6 specifically shows the contents of the system operation in step 39. In the figure, editing and proofreading are performed in step 43, and it is confirmed in step 44 whether the editing and proofreading processing is completed.

Next, when the 4 key "'1" is entered, it is checked in step 45 whether or not to register the document on the floppy disk. If it is registered, the document is loaded on the floppy disk in step 46, and the completion is confirmed in process 47. The process jumps to step 35 shown in FIG.

If it is not registered in step 45, the process jumps to step 35 and the process described above is performed.

In this way, if it is desired to switch the input device during processing, the editing/proofreading work can be temporarily interrupted and the input device can be easily switched in a short time by operating the flowcharts.

Further, if printing is to be performed on the printer after step 44, the process is performed by printing with the printer in step 48 and then checking for completion in step 49.

According to this embodiment, when switching the input device during a processing operation, it can be done in a short time without any malfunction, and the operability can be improved.

〔Effect of the invention〕

According to the present invention, since input devices can be switched in a short time without malfunction, the operability of the input device can be improved.
