Abstract

PURPOSE:To use a mouse even if a private program for mouse is not executed by means of software by substituting a moving quantity data and mouse button data, which can be obtained by means of using the mouse for the key code of a keyboard. CONSTITUTION:When the mouse is moved from a point P1 to a point P4 by setting a point P0 as an origin, a direction key code output circuit 5 outputs direction key code data 11 of plural moving key codes in the direction of an (x) axis '+ x' or '- x' and moving key codes in the direction of a (y) axis '+ y' or '- y' to an OR circuit 9. When a mouse button detection circuit 7 detects the depression and the release of a mouse button, mouse button data 12 is generated, and is transmitted to a mouse button key code output circuit 8. The mouse button key code output circuit 8 reads the key code corresponding to mouse button data 12 from a mouse button code storage part 6 and it is outputted to the OR circuit 9 as mouse button key code data 13.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mouse input device for generating key codes.

[Conventional technology]

Conventionally, this type of mouse input device has a hardware interface different from that of a keyboard input device, and the mouse input device can only be used when the program itself performs processing dedicated to the mouse input device.

[Problem to be solved by the invention]

The conventional input device described above requires two interface connectors, a keyboard and a mouse, on the computer main body. Furthermore, when using two input devices, a mouse and a keyboard, in software, there is a drawback in that a program must be created to perform input from each input device.

[Means to solve the problem]

A mouse input device that generates a key code according to the present invention includes a movement amount detection circuit that generates mouse movement amount data, a direction key code storage section that holds key codes corresponding to a plurality of direction keys, and a movement amount detection circuit that generates mouse movement amount data. A directional key code output circuit that generates a plurality of directional key code data by referring to the directional key code storage unit in response to movement amount data sent from the circuit, and a mouse that detects whether a mouse button is pressed or released. a button detection circuit; a mouse button key code storage unit that holds a plurality of key codes to be generated when a mouse button is pressed and released; A mouse button key code output circuit that generates mouse button key code data by referring to a mouse button key code storage unit, and outputs the key code sent from the direction key code output circuit and the mouse button key code output circuit. and an OR circuit.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, FIG. 2(a) is an explanatory diagram showing changes in the moving position of the embodiment,
FIG. 2(b) is an explanatory diagram showing the key code data generated at that time.

The mouse input device of this embodiment includes a CPUI, a keyboard input device 2, a direction key code storage section 3, a movement amount detection circuit 4, a direction key code output circuit 5, a mouse button key code storage section 6, and a mouse button. It consists of a detection circuit 7, a mouse button key code output circuit 8, and an OR circuit 9.

Next, the operation of this embodiment will be explained.

First, a case in which data is input using a keyboard input device in this apparatus will be described. The key code generated by the keyboard input device 2 is sent to the CPU via the OR circuit 9.
1/\ will be sent.

Next, a case in which it operates as a mouse will be explained. Movement amount data 10 is generated by the movement amount detection circuit 4,
The signal is sent to the direction key code output circuit 5. The direction key code output circuit 5 reads out the key code corresponding to the movement amount data 10 from the direction key code storage section 3 and sends it to the OR circuit 9 as the direction key code data 11 a necessary number of times. That is, as shown in FIG. 2(a), move the mouse to point P.

When moving from point P1 to point P2 to point P3 to point P4, the direction key code output circuit 5 is as shown in Fig. 2(b).
As shown in , multiple XM direction movement key codes “+x
” or “-x, y-axis movement key code “'+
The direction key code data 11 of y'' or '-y'' is output to the OR circuit 9.

Further, when the mouse button detection circuit 7 detects the depression or release of a mouse button, mouse button data 12 is generated and sent to the mouse button key code output circuit 8.

The mouse button key code output circuit 8 reads out the key code corresponding to the mouse button data 12 from the mouse button key code storage section 6 and outputs it to the OR circuit 9 as the mouse button key code data 13. In other words, point P shown in Figure 2 (a)! If the mouse button is pressed down at point P3, P'' in FIG. 2 <b) is output, and when the mouse button is released at point P3, °F°'' is output.

In this way, the data shown in FIG. 2(b) is generated as the key code data 14 output from the OR circuit 9 to the CPUI.

〔Effect of the invention〕

As explained above, the present invention allows the mouse to be used without running a dedicated program for the mouse using software by substituting the movement distance data and mouse button data obtained by using the mouse with the key code of the keyboard. There is an effect that it can be done. Furthermore, there is no need for separate interface connectors for the mouse and keyboard input devices.
