Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buffer device and the like used when digital data is communicated between a plurality of computers via a public telephone line.

[0002]

2. Description of the Related Art Conventionally, when transferring specific data between a plurality of computers, the plurality of computers are
In the case of a LAN environment, the shared directory is mounted, a specific name is saved on one computer to save the specific data, and the other computer reads the data by calling a file having the file name. Alternatively, send the e-mail with the specific data attached,
The other computer retrieves the specified data from the e-mail.

When not in a LAN environment, the following operation is required using a portable medium, for example, a floppy disk. This series of operations involves initializing a floppy disk on one computer, saving data with a file name, replacing the floppy disk with the other computer, reading the file name, and reading the data.

[0004] On the other hand, many operations as described above are not required inside one computer. That is, the exchange of specific data that existed in one area,
This operation can be performed by a so-called copy-and-paste or cut-and-paste operation of designating specific data with an input device (for example, a mouse) and moving the specific data to another area. This will be described in more detail with reference to FIG.

[0005] One computer 10 and a mouse 30B as an input device are electrically connected. Mouse 30
B includes a detection mechanism 31 for detecting operation information such as movement of a pointer moving on the output screen of one computer 10 and clicking with the pointer, and a data transmission unit 32 for transmitting the operation information to the computer 10. ing. When the connection to the computer 10 is made by a connection cord, the electricity required by the mouse 30B is supplied from the computer 10, but in the case of a wireless connection, an independent power supply 35 is supplied to the mouse 30B. Have or
It is supplied wirelessly from the computer 10.

[0006] With respect to certain data on the output screen of the computer 10, operation contents such as movement of the pointer by the mouse 30B and click by the pointer are electrically converted and transmitted from the data transmission unit 32 to the computer 10.
Then, the data specified by the copy or cut command is stored in the memory in the computer 10. Then, after the next operation of the mouse 30B, for example, an operation of moving a pointer using a cursor key or the mouse 30B,
The data transmission unit 32 transmits the movement information to the computer 10, and the paste operation is performed.

[0007]

However, the process of transferring data is the same even with information of only a few bits such as an e-mail address and a homepage address. Therefore, when a plurality of computers are located in close proximity to each other, hand-written memos are often handed to the user because the work is troublesome. Then, as a matter of course, the possibility of a transcript error or an input error increases.

Further, when a computer that wants to send and receive data is physically far apart, it takes time to send and receive data, whether it is a handwritten memo or a floppy disk. If an environment using a LAN or communication network is in place, the need to physically move people or things can be saved, but `` Save the specific data with a file name and use the other computer to The task of "calling a file from a computer" could not be reduced.

The problem to be solved by the present invention is to provide a technique that can perform transfer of specific data as easily as copy and paste or cut and paste in one computer by using a public telephone line. Is to do. The object of the invention described in claim 1 is:
It is an object of the present invention to provide a device which can transfer specific data in a plurality of computers as easily as copy and paste or cut and paste in one computer by using a public telephone line.

(Operation and Effect) First, the mouse 30 is
It is electrically connected to one computer main body 10 using a connection device. The mouse 30A is electrically connected to another computer main body 20 using a connection device. Next, a part or the whole of the data output by one computer main body 10 is copied or cut by the mouse 30 to be designated data via the detection mechanism 31 and the data transmission unit 32. The designated data is stored in the data receiving unit 12, the OS 11, the data transmitting unit 1 of the computer main body 10.
3 and stored in the buffer 34 via the data receiving unit 33 of the mouse 30. Then, the designated data stored in the buffer 34 is transmitted to the other mouse 30A via the data communication function unit 37 and the public telephone line 40.

Transmission data as designated data transmitted via the public telephone line 40 is received by the data communication function unit 37 of the mouse 30A and stored in the buffer 34. Then, the designated data stored in the buffer 34 is transmitted from the data transmission unit 32 to another computer main body 20. Then, the designated data is transferred to the other computer main body 20, and the designated data can be used in the other computer main body 20.
