Abstract

PURPOSE:To select a key input detecting means in accordance with the purpose of application, by selecting and actuating either one of plural key input detecting means of different keying data compensating systems. CONSTITUTION:For a composite system unit, plural key input detecting means 1 and 2 are provided in parallel to each other between a keyboard and the main body of the system unit. Then the means 1 and 2 are switched to each other. These means have different keying data compensating systems, that is, the means 1 and 2 apply a key lock-out system and N key roll-over system respectively. A switching means contains a switching mechanism 3 and an inverter 4. The output of the mechanism 3 is applied to the means 1 and at the same time inverted by the inverter 4 to be applied to the means 2. Thus a means 1 or means 2 is selected.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a key manpower device MK having a key manpower detection means.

The key force detection means in Shinham's key force device compensates for the keystroke data when two or more keys on the keyboard are pressed at the same time. There are over one-way types, etc. The 2-key lockout method is a method that stops inputting keys when 21 or more keys are pressed at the same time.
N-key lock-no-gout system When keys 211- and above are pressed +Tf11 at the same time, inputs from a plurality of keys being pressed at the same time are taken in in the order in which they are pressed. In other words, the input from the most recently pressed key is taken in (f+). Existing key power devices do not use any one of the two keys, the pull-out method, the N-key rollover one-way method, etc. as a key power detection means.

The key press data compensation method is fixed and cannot be changed. By the way, key human-powered devices have until now been used individually in system units such as data processors and word processors, but it is now being considered that they may not be used in complex system units such as H&-H data processors and word processors. There is. In this complex system, depending on the purpose of use, it is better to use a 2-key lockout method as the key force detection means for the key-powered device, or a 3-way type with N-key rollover on one side, but with existing key-powered devices, It is not possible to switch the one-key data compensation method as described above.

In addition, the human-powered key device can change the hit data compensation method depending on the difference in hitting and axis characteristics due to the user's familiarity, etc. It is possible to reduce mistakes and improve input efficiency by increasing the speed of keystrokes. Yes, but is this a key human power detection method?
It is impossible because it is

SUMMARY OF THE INVENTION An object of the present invention is to improve the above-mentioned drawbacks and to provide a key-powered device capable of switching the key-powered detection means.

The present invention will be described below with reference to the drawings.

The figure shows an embodiment of the invention. In this embodiment, a plurality of key force detection means 1 and 2 are installed in parallel between the keyboard and the main body in a complex system unit, and a means for switching between them is provided. The key force detection means 1.2 have different keystroke data compensation methods, one being a two-key lockout type (1) and the other being a one-key N-key rollover type (2). The switching means consists of a switching mechanism 3 and an impark 4, and at the same time when the output of the switching mechanism 3 is not applied to the key force detection means 1, it is inverted by an inverter 4 and applied to the key force detection means 2.

The output of the switching mechanism 3 is 1' K. In other words, this output enables the key force detection means 1 to operate, detects the key force from the keyboard, and outputs it to the main body of the composite system unit. At this time, the output of inverter 4 is “0°
, and the key human power detection means 2 becomes inoperable. Also, if the output of the switching mechanism 3 is switched to °O, the key force detection means 1 becomes inoperable.Then, the output of the inverter 4 becomes "1@," and the key force detection means 2 becomes operable, and the keyboard Detects key human power and outputs it to the main body of the complex system unit.

Note that the key human power detection means 1 and 2 can be realized by a single-chip microcomputer instead of using separate circuits.

As described above, according to the present invention, the key human power device is configured to select and operate one of a plurality of key human power detection means with different keystroke data compensation methods, so that the complex system unit can select and operate the key power detection means according to the purpose of use. By changing the key force detection means according to the keystroke characteristics due to the user's familiarity, etc., it is possible to reduce keystroke errors and improve input efficiency by increasing the speed of keystrokes. It becomes possible.
