Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse type position input device used as an external input means for personal computers, word processors and the like.

[0002]

2. Description of the Related Art When moving a cursor on a display device in a personal computer or a word processor,
The mouse-type position input device is easier to operate than the keyboard input.

In this mouse type position input device, the cursor on the display device can be freely moved by rolling of the rotating ball on the bottom of the device.

[0004]

However, in the above-mentioned prior art, the input of the horizontal line and the vertical line, and the input for which a fixed amount of movement is desired, have to rely on the input from the keyboard.

Further, if the position of the mouse-type position input device moves during input from the keyboard, normal position input cannot be performed.

An object of the present invention is to provide a position input device capable of inputting horizontal and vertical lines and inputting a desired amount of movement.

[0007]

The above object is to provide a position input device with a switch having a cursor function, and to provide an input selector switch for switching between an input from a rotating ball and an input from a cursor operation switch. To be achieved.

[0008]

With the above structure, when the cursor operation switch is pressed while pressing the changeover switch, the cursor on the display device moves. In this case, even if the rotating ball rolls, it is ignored.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing the external structure of the position input device according to the present invention, and FIG. 2 is a block diagram showing the control structure of the position input device.

This position input device is provided with an execution switch 2, a release switch 3, an up cursor switch 4, and a down cursor switch 5 on the upper surface of the device main body 1, and input switching is performed on the left side surface of the device main body 1. Equipped with a switch 6,
The connection cord 11 connects to a personal computer or the like.

The execution switch 2 and the release switch 3 are installed on the front left and right sides of the upper surface of the apparatus main body 1, and the up cursor switch 4 and the down cursor switch 5 correspond to the execution switch 2 and the release switch 3. In between, the upper cursor switch 4 and the lower cursor switch 5 are installed in this order from the front, and the input changeover switch 6 is installed on the left side surface of the apparatus main body 1.

In the apparatus body 1, a rotating ball 10 rolling on a desk, encoders 8 and 9 for outputting a pulse signal by the rolling of the rotating ball 10, an execution switch 2, a release switch 3, The upper cursor switch 4, the lower cursor switch 5, and the input selector switch 6 are connected to the control circuit 7.

FIG. 3 is a flow chart showing the processing contents of this position input device, and the processing contents of one embodiment of the present invention will be described with reference to this drawing.

When the input selector switch 6 is not pressed, that is, when the switch is OFF (50), the rolling balls 10 in the apparatus main body 1 roll the input signals from the encoders 8 and 9 to the control circuit 7. When it is input (60), the control circuit 7 outputs a signal corresponding to the rolling direction input from the encoders 8 and 9 through the connection cord 11 (61), whereby the cursor on the display device
It moves according to the rolling direction.

When the execution switch 2 is input (62) and the release switch 3 is input (64).
The control circuit 7 outputs the respective signals of the execution switch 2 and the release switch 3 through the connection cord 11 (63) (65).

Next, the case where the input changeover switch 6 is pressed, that is, the case where the switch is ON (50) will be described.

When the execution switch 2 is input (5
1), the control circuit 7 generates a left cursor signal (52),
When the release switch 3 is input (53), the control circuit 7 generates a right cursor signal (54), and the connection cord 11
Output through.

When the upper cursor switch 4 and the lower cursor switch 5 are input (55) (57), the control circuit 7 generates an upper cursor signal and a lower cursor signal (56) (58), respectively. ), And output through the connection cord 11.

[0020]

As described above, according to the present invention,
When the input select switch is pressed, the execution switch, the release switch, the up cursor switch, and the down cursor switch perform the same cursor function as the cursor key on the keyboard, and the cursor on the display device can be changed arbitrarily. You can move it any number of times in the direction.

Further, when the input changeover switch is pressed, the input signal from the encoder due to the rolling of the rotating ball is ignored, so that even if the input device is moved by mistake, the input as the operator desires can be obtained. it can.
