Abstract

PURPOSE:To transmit data without connecting a connector by bringing part of OA equipment such as a personal computer and a word processor and part of peripheral equipment such as an electronic pocketbook into contact with each other and giving the both the relation of electrostatic coupling. CONSTITUTION:When the data are transmitted from the OA equipment such as a personal computer and a word processor to the electronic pocketbook 2, the data applied to a transmitter receiver 8 from a bus line 10 are encoded and applied to electrodes 6 and 7. At this time, the polarities '+' and '-'of the electrodes are directly changed corresponding to the data. In another way, an AC system is employed and '1' and '0' may be defined corresponding to the frequency. The method is optional. The electrodes 4 and 5 of the electronic pocketbook 2 are arranged opposite the electrodes 6 and 7 respectively, so voltages are induced at the electrodes 4 and 5 and amplified and regenerated by the transmitter receiver 9 to transmit the data to the bus line 11. Exactly the same operations as above can be performed even when the data are transmitted from the electronic pocketbook 2 to the OA equipment side such as a personal computer and a word processor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a communication system between an OA device such as a personal computer and a word processor and a peripheral device represented by an electronic notebook.

[0002]

2. Description of the Related Art FIG. 5 shows an O of a conventional personal computer, word processor, etc.
An example of data communication between a device A and a peripheral device such as an electronic notebook will be shown. 1'is a personal computer, an OA device such as a word processor, 2'is an electronic notebook, 15 is a communication cable, 16 is a connector for connecting the communication cable 15 to an OA device 1'such as a personal computer and a word processor, and 17 is a communication device. Electronic notebook 2'of cable 15
It is a connector for connection with. The example of the conventional data communication shown in FIG. 5 is a wired connection as is clear from the figure, and data communication is performed using the communication cable 15. In the case of the conventional example of FIG. 5, since the communication is wired,
The reliability of the communication itself is high, but on the other hand, (1) it takes time and effort to connect the communication cable 15 to each device, and (2) the reliability of the connector increases as the number of times the connector is attached and detached increases. There are drawbacks such as deterioration, and (3) as OA devices such as personal computers and word processors and peripheral devices such as electronic notebooks are downsized, the proportion of connectors increases, which is a constraint for downsizing. On the other hand, in order to eliminate this drawback, it is conceivable to connect both devices by wireless communication, but in this case too, the transmitter / receiver and antenna may be downsized and power consumption may be limited. Not not.

[0003]

In order to solve the above-mentioned drawbacks of the prior art, the present invention does not need to be separate from each other particularly in data communication between an electronic notebook and an OA device such as a personal computer or a word processor. In addition, even if it is necessary to be separated, from the viewpoint that it can be easily applied by adding a wired connection to the present invention, without using a connector,
A part of OA equipment such as a personal computer and a word processor and a part of peripheral equipment such as an electronic notebook are brought into close contact with each other, and an electrostatic coupling relationship is provided between the two so that data communication can be performed. is there.

[0004]

That is, the feature of the present invention resides in that a part of the devices that want to perform data communication face each other.

[0005]

1 to 4 show an embodiment of the present invention. In FIG. 1, 1 is an OA device such as a personal computer and a word processor, 2 is a peripheral device such as an electronic notebook, and 3 is a state in which an electrode mounting portion which is a main component of the present invention is housed. FIG. 2 shows a state in which a peripheral device 2 such as an electronic notebook is placed on an electrode mounting portion 3'pulled out from an OA device such as a personal computer or a word processor in order to connect it to an OA device 1 such as a personal computer or a word processor. FIG. 3 shows the relationship between the electrodes attached to the OA equipment 1 such as a personal computer and a word processor in FIG. 2 and the electrodes attached to the peripheral equipment 2 such as an electronic notebook in an easy-to-understand manner. Reference numerals 4 and 5 denote electrodes attached to the peripheral device 2 such as an electronic notebook, and 6 and 7 denote electrodes attached to the OA device 1 such as a personal computer and a word processor. Also,
Both 8 and 9 indicate a data transmitter / receiver, and 10 and 11 indicate a data bus line. Further, FIG. 4 shows the relationship of the electrodes in FIG. 3 in a mounted state. Next, this operation will be described with reference to FIG. Now, consider a case where data is transmitted from the OA device 1 such as a personal computer or a word processor to the electronic notebook 2. The data applied to the transceiver 8 from the bus line 10 is encoded and applied to the electrodes 6 and 7. In this case, the voltage may be applied by changing + and-in correspondence with the data directly, but it may be defined as AC method and 1 or 0 may be defined in correspondence with the frequency. is there. On the other hand, since the electrodes 4 and 5 on the side of the electronic notebook 2 are close to the electrodes 6 and 7, respectively, a voltage is induced in each electrode and the data is transmitted to the bus line 11 by being amplified and reproduced by the transceiver 9. can do. The above operation can be described in the same manner when data is transmitted from the electronic notebook 2 to the OA device such as a personal computer or a word processor. Also,
If the OA device such as a personal computer or word processor and the peripheral device such as an electronic notebook are separated, use an extension communication cable.
It is also clear that the purpose is reached by attaching electrodes at the ends of the cable.

[0006]

As described above, according to the present invention, data can be transmitted between an OA device such as a personal computer and a word processor and a peripheral device such as an electronic notebook without connecting a connector. INDUSTRIAL APPLICABILITY The present invention is not limited to OA equipment, but is widely applied to a communication interface of data communication equipment,
Workability, operability and reliability can be improved.
