[0014]

[Action]

 (1) It has a switch means for selecting and instructing the usage mode of either the OADG keyboard or the original keyboard, and (2) and is provided with two sets of keytop parts displaying Caps Lock and Control. (3) The user uses the switch means for selecting and instructing a desired usage pattern to select and use one of the OADG keyboard and the original keyboard, and a set of keys corresponding to the selection command. By exchanging the top parts, the key layouts of both the OADG keyboard and the original keyboard can be freely selected and used in combination.

[0015]

[Example of device]

 An embodiment of the present invention will be described in detail with reference to FIGS. 1, 2, 3, 4, 5, and 6. FIG. 3 is a diagram showing the respective key layouts of Caps Lock and Control on the OADG keyboard 1 and the original keyboard 2. In the figure, 10 and 20 are the Control key and the Caps Lock key 100 and 200 of the OADG keyboard 1, respectively, and the Caps Lock key and the Control key of the original keyboard 2, respectively. Shape is different.

Therefore, in the present invention, as shown in FIG. 2, Caps Lock is displayed as a replacement key top for enabling both the OADG keyboard 1 and the original keyboard 2 to be used. It has two sets of key top parts that display key top and control. That is, as a replacement key top for using the OADG keyboard 1 as the original keyboard 2, a key top part 11 showing a Caps Lock in the same shape as the original Control key top 10 and an original Caps Lock key top 20. A keytop part 21 showing Control in the same shape as, and a keytop showing Control in the same shape as the original Caps Lock keytop 100 as a replacement keytop for using the original keyboard 2 as the OADG keyboard 1. The component 110 is a keytop component 210 in which the Caps Lock is printed in the same shape as the original Control keytop 200, and in particular, it is displayed by silk printing or stamping.

The user replaces and replaces these key tops 10, 20, 100, 200 and the key top parts 11, 21, 110, 210 according to the usage pattern.

Next, a specific circuit configuration for realizing the usage patterns of both the OADG keyboard 1 and the original keyboard 2 will be described with reference to FIG. The keyboard of the present invention includes a switch 300 for the user to select and instruct one of the above two usage patterns. The figure shows a circuit configuration for realizing the use of the OADG keyboard 1 as the original keyboard 2. Although a specific drawing of the switch 300 is not shown, the mounting position on the keyboard and the shape / type of the switch 300 can be selected with a user's finger, a driver, or a dedicated tool. It goes without saying that there is no particular limitation if possible.

Further, an input / output port having a key matrix (two-dimensional expression of x1-x16 and y1-y8) and a key code table for generating a scan code corresponding to this key matrix is provided by, for example, Intel Corporation. The semiconductor device (87C54: QFP type) 400 manufactured by Intel Corporation is used as an example to realize it as disclosed in FIG. 1, and the key matrix (two-dimensional representation of x1-x16 and y1-y8) and Intel The terminal connection relationship with a specific signal between the semiconductor device (87C54) 400 is as shown in the figure.

Further, by connecting a signal from the switch 300 for newly instructing the usage pattern to the currently unused terminal 10, for example, when the switch 300 is off (low level), the original key The array Caps Lock (20) is at the left end of the third column, and Control (10) is at the left end of the first column. Here, when the user desires the original keyboard 2, the switch 300 is turned on (high level) to instruct switching of the key code table. That is, the key code table (Caps Lock at coordinates x10 and y6 of the key matrix and Control at coordinates x16 and y1) is changed as a key array at the left end of the first column for Caps Lock and for the left end of the third column for Control. To do.

Here, in the present embodiment, of the three empty terminals (No. 5, No. 10, No. 23), the No. 10 terminal is used, but it is clear that other terminals may be used. . Therefore, in the setting of the input / output port shown in FIG. 6, the input port is instructed (program setting) for the empty terminal to which the switch 300 is connected. At this time, as shown in FIG. 5, the user replaces the original Cap s Lock key dop 20 with the original Cap s Lock key dope 20 by replacing the original Control key top 10 with the Caps Lock displayed in the same shape as the original Control key top 10. Replace with the keytop part 21 that has the same shape and display Control. The meaning of the signal level from the switch 300 does not hinder the realization of the present invention even if the low level and the high level are reversed.

Although the case where the OADG keyboard 1 is originally used as the original keyboard 2 (111) has been described above, the same method / method can be used when the original keyboard 2 is used as the OA DG keyboard 1 (211) in the opposite case. It is clear that this can be achieved by means. That is, when the use of the OA DG keyboard 1 (211) is instructed by the instruction signal from the switch 300, as shown in FIG. 4, Caps Lock is at the left end of the third row and Control is at the left end of the first row. The key code table is changed as the key arrangement of the parts, and the user replaces it with the key top part 110 that displays Control in the same shape as the original Caps Lock key top 100, and replaces it with the original Control key top 200. Replace with the key top component 210 that has Caps Lock displayed on its shape.

[0023]

[Effect of device]

 Freely select the key layouts of both the OADG keyboard and the original keyboard. Since a keyboard having multiple usable usage patterns can be realized, (1) two types of usage patterns can be realized with one keyboard product, and the product cost is reduced. In addition to lowering the price, it is possible to reduce the price and (2) to save the user the effort to get used to the two types of keyboard layouts, and to prevent product accidents etc. due to erroneous input caused by inexperience. You can
