Abstract

PURPOSE:To select exactly and automatically a code table corresponding to a kind of a keyboard by performing the wiring corresponding to a key array of its keyboard, to a connector, and coupling the keyboard and a processor through the connector. CONSTITUTION:First of all, in case a keyboard 11 is connected to a processor 14 by coupling the connectors 12, 13, a signal line 17 becomes a high level by an operation of a connecting line 20. As a result, a memory 15 is selected automatically, and a code table corresponding to the keyboard 11 is used. Also, in case a keyboard 21 is connected to the device 14 by coupling the connectors 22, 13, the signal line 17 becomes a low level by an operation of a connecting line 23. As a result, a memory 16 is selected automatically, and a code table corresponding to the keyboard 21 is used. Accordingly, a user brings a keyboard of an array whose use is desired and can use it by only coupling a socket.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a keyboard device capable of selecting a code table corresponding to the character arrangement of the keyboard.

Structure of conventional example and its problems Figure 1 shows an example of a conventional keyboard device.
2 is a keyboard, 2 is a processing device, 3 is a connector, and 4 and 5 are memories storing code tables corresponding to the key arrangement of the keyboard. The keyboard 1 has two types of keyboard layouts for kana characters: a JIS layout and an IWW order layout.

The processing device 2 does not support these two types of key layouts, so it has a code table for the JIS layout stored in the memory 4 and a code table for the IWW order layout stored in the memory 5. There is. Which key arrangement to use is determined by setting the terminal 7 to a high level or a low level using a changeover switch 6.

In the device configured as described above, it is possible to respond functionally by setting the changeover switch 6 in accordance with the key arrangement of the keyboard 1.

However, it is necessary to set the changeover switch 6 on the main body side according to the key arrangement of the keyboard 1, and if this does not match well, trouble may occur where the display on the key top and the character input manually are different. Become.

OBJECTS OF THE INVENTION An object of the present invention is to provide a keyboard device that prevents the above-mentioned troubles from occurring.

Structure of the Invention The present invention is capable of automatically selecting a code list by connecting a keyboard and a processing device via the connector by wiring the connector according to the key arrangement of the keyboard. It is composed of

Description of examples The present invention will be explained below along with examples.

In Figure 2, 11 is a keyboard with a JIS arrangement of ephemeral characters, 12 is a connector provided on the keyboard side,
13 is a connection provided on the processing device side; 14 is a processing device;
6 is a memory that stores a code table for JIS arrangement, 16 is a memory that stores a code table for Aiweo order arrangement, 17
is a signal line to which a signal for selecting the memory 6.16 is added. 18E1 is a power line to which a voltage of 10B is applied. 19 is a ground wire. 20 is a connection line for connecting the power line 18 and the signal line 17 when the connector 2.13 is connected.

FIG. 3 also shows a different keyboard.

Reference numeral 21 represents a keyboard arranged in the iWW order, and reference numeral 22 represents a connector on the keyboard side. 23 is the connector 22.1
This is a connecting wire that connects the ground wire 19 and the signal wire 17 when the wires 3 are connected. Note that the configuration of the processing device connected to the connector 13 is the same as that shown in FIG.

Next, the operation of the above embodiment will be explained.

When the keyboard 11 is first connected to the processing device 14 by coupling the connectors 12 and 13, the signal line 17 becomes high level due to the action of the connection line 20.

Then memory 15 is automatically selected and keyboard 11
If the keyboard 21 is connected to the processing device 14 by connecting the connectors 22 and 13, the connecting line 23 will be used.
Due to this function, the signal line 17 becomes low level.

Then memory 16 is automatically selected and keyboard 21
The corresponding code table will be used.

Therefore, the user can use the keyboard by simply bringing the keyboard with the key arrangement that he/she wants to use and connecting the sockets 12 and 13. At this time, manual setting operations using a changeover switch or the like as shown in FIG. 1 are not necessary at all.

In the above embodiment, the case where there are two types of key layouts has been explained, but even when there are three or more types, the number of code designation signal lines 17 can be increased, and the code table can be designated by a combination of these signal levels. By doing so, it is possible to realize a device that does not require any setting operations. In addition, in the embodiment shown in FIG. 2, a high level signal terminal corresponding to the power supply line 18 was separately provided, but by pull-amplifying the code designating signal line 17 with a resistor, the high level signal terminal was removed. can do. In this case, the connection line 20 of the connector 22 connected to the JIS layout keyboard 11 is unnecessary.

Effects of the Invention As is clear from the above embodiments, according to the present invention, it is possible to reliably and automatically select a code table according to the type of keyboard.
