2. Description of the Related Art Conventionally, a data input device having a mouse member has been known as a typical data input device for inputting two-dimensional coordinates. This data input device includes a ball that rotates by friction with the table by horizontally moving a mouse member two-dimensionally on a table, and a X-axis and a Y-axis that are arranged so as to rotate simultaneously with contacting the ball. It is composed of two rotary encoders for detecting each moving direction and moving amount by its rotation, and converts its output into a pulse signal and inputs it to a personal computer or the like.

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

First, a first embodiment of the present invention will be described. In the data input device of the first embodiment, two vibrating gyroscopes for X-axis and Y-axis are arranged in a mouse member so that each becomes a right angle, and a change in angular velocity given to each vibrating gyroscope is provided. The moving direction is determined based on the polarity obtained from the above, and the polarity is stored for a certain period of time.

Then, the moving direction and the moving speed obtained in this case are converted into a pulse signal and output.

Therefore, according to the data input device of the first embodiment, with the mouse member held in the air,
By turning on / off a switch for starting / stopping an external output while giving an angular velocity, that is, rotation in an arbitrary direction of the X-axis or the Y-axis, the moving / stopping and the moving speed are switched to a high speed or a low speed. It becomes possible.

Hereinafter, the first embodiment will be described with reference to the drawings.

FIG. 1 is a perspective view of a ceramic gyro element 1 (or 2) of a vibrating gyroscope used in this embodiment. FIG. 2 shows an example of a signal obtained by giving the ceramic gyro element 1 (or 2) an angular velocity in the direction of arrow a or b in FIG. As shown in FIG. 2, the amplitude polarity of the signal is determined by the direction of the angular velocity applied to the ceramic gyro element 1 (or 2).

As shown in FIG. 3, the data input device according to the first embodiment has an X-axis ceramic gyro element 1 and a Y-axis ceramic gyro element.
The ceramic gyro elements 2 are arranged at right angles to each other, and the signals of the ceramic gyro elements 1 and 2 are received by the amplifier circuits 3 and 4, respectively. Then, the polarity of this signal is monitored by the one-chip microcomputer 6 having a built-in A / D converter, and the moving direction for each of the X axis and the Y axis is stored from the signal for a certain period of time. Also, start / stop external output to start / stop external output.
The on / off state of the stop switch 5 is monitored by the one-chip microcomputer 6 and the ceramic gyro elements 1 and 2 are monitored.
The presence / absence of a polarity signal from the controller, the state of its storage means, and the on / off state of the external output start / stop switch 5 are determined, and the values are converted into pulse signals indicating the corresponding moving direction and speed. Then, this pulse signal is input to a personal computer or the like through the cable 7.

Here, as shown in FIG. 4, the determination of the directionality is made when the signals of the ceramic gyros 1 and 2 exceed threshold voltages + Vth.-Vth provided for both polarities.

The data input device according to the present embodiment is constructed by arranging the components shown in FIG. 3 in a mouse member 8 as shown in FIG.

Next, a second embodiment of the present invention will be described. In the data input device of the second embodiment, two vibrating gyroscopes for the X axis and for the Y axis are arranged in a mouse member so that each vibrating gyroscope is at a right angle, and a change in angular velocity given to each vibrating gyroscope is provided. The moving direction is determined by the polarity of the signal obtained by the above, and the external output is started. Thereafter, the external output is stopped by detecting the polarity opposite to the signal obtained by the change in the angular velocity given to each vibrating gyroscope.

Therefore, according to the data input device of the second embodiment, while the mouse is held in the air, an angular velocity, that is, a rotation is given in an arbitrary direction of the X axis or the Y axis, thereby providing an external device. Output is started and coordinate movement can be performed. In addition, by applying rotation in the opposite direction to the angular velocity, that is, in the direction opposite to the direction in which the external output was started, the external output is stopped, and the coordinate movement can be stopped.

The second embodiment will be described below with reference to the drawings.

The ceramic gyro element 1 (or 2) of the vibrating gyroscope used in the present embodiment is provided with an arrow in FIG. By giving an angular velocity in the direction of a or b, a signal as shown in FIG. 2 is obtained, and the amplitude polarity of the signal is determined by the direction of the applied angular velocity.

As shown in FIG. 6, the data input device according to the second embodiment has an X-axis ceramic gyro element 1 and a Y-axis ceramic gyro element.
The ceramic gyro elements 2 are arranged at right angles to each other, and the signals of the ceramic gyro elements 1 and 2 are received by the amplifier circuits 3 and 4, respectively. The polarity of this signal is monitored by a one-chip microcomputer 6 having a built-in A / D converter, external output is started and stopped, and data is input to a personal computer or the like through a cable 7.

Here, as shown in FIG. 7, the timing of the determination of the direction and the start / stop of the external output is such that the signals of the ceramic gyros 1 and 2 correspond to the threshold voltages + Vth.-Vth provided for both polarities. It is done by exceeding.

The data input device according to the second embodiment is configured by arranging the components shown in FIG. 6 in a mouse body 8 as shown in FIG.

Next, a third embodiment of the present invention will be described. In the data input device of the third embodiment, two vibrating gyroscopes for X axis and Y axis are arranged in a mouse member so that each vibrating gyroscope is at a right angle, and a change in angular velocity given to each vibrating gyroscope is provided. The moving speed and the moving direction are determined based on the peak value and the polarity of the amplitude of the signal obtained by the above, and external output is performed. Thereafter, the peak value and the polarity of the amplitude obtained by the change in the angular velocity given are detected, the addition and subtraction with the previously obtained peak value are performed, and the moving speed and the moving direction are determined based on the obtained result. Output is performed and this process is repeated.

For example, for each vibrating gyroscope, (+)
When a strong angular velocity is given in the direction, its external output is
The moving speed is increased in the direction corresponding to the (+) direction and output. After that, when the angular velocity is weakly applied in the (-) direction,
The peak value obtained in the (-) direction is subtracted from the peak value obtained in the (+) direction. As a result, the value of the peak value becomes smaller while the polarity remains (+), and the output is made to the outside so that the moving speed becomes slower. Further, when an angular velocity is strongly applied in the (-) direction, the same calculation is performed, and as a result, (-)
Externally output in the direction corresponding to the direction at the moving speed corresponding to the calculation result. Therefore, according to the data input device of the third embodiment, while the mouse member is held in the air, the angular velocity, that is, the rotational speed given in any direction of the X axis or the Y axis, that is, the rotation is given. Then, the moving speed and the moving direction are determined, and the external output is performed.

Hereinafter, the third embodiment will be described with reference to the drawings.

The ceramic gyro element 1 (or 2) of the vibrating gyro used in the present embodiment is provided with an arrow in FIG. 1 in the same manner as the first embodiment. By giving an angular velocity in the direction of a or b, a signal as shown in FIG. 9 is obtained, and depending on the direction and strength of the applied angular velocity, the amplitude polarity and amplitude of the signal can be obtained.

In the data input device of the third embodiment, as shown in FIG. 10, an X-axis ceramic gyro element 1 and a Y-axis ceramic gyro element 2 are arranged so as to be perpendicular to each other. The signals of these ceramic gyro elements 1 and 2 are received by amplifier circuits 3 and 4, respectively. Then, the one-chip microcomputer 6 having a built-in A / D converter detects the peak value and the polarity of the amplitude of this signal, and performs an arithmetic process to convert the signal into a signal indicating the moving speed and the moving direction. The data is input to a personal computer or the like through 7.

In FIG. 10, the external output permission switch 9
Can be turned on to allow the external output, and turned off to stop the external output, arbitrarily stop the movement, and clear the previous peak value.

As shown in FIG. 11, when the signals of the ceramic gyros 1 and 2 exceed the threshold voltages + Vth.-Vth provided for both polarities, the polarity is determined, and the peak value detection is started. In the example shown in FIG. 11, the obtained peak value P1 is set such that the moving direction is (+) and the moving speed PV = | P1 |. Next, based on the obtained peak value P2, the moving direction is set to (+) when P1−P2> 0, and the moving speed PV = | P1−P2 |. With the peak value P3 obtained next, the moving direction is set to (-) when P1-P2-P3 <0, and the moving speed PV = | P1-P2-P3 |
And

Here, | P1 |> | P2 | and | P
3 |> | P1 | + | P2 |, and the signal indicating the actually output moving speed is converted into a signal corresponding to the moving speed PV.

The data input device according to the third embodiment includes a mouse member 8 as shown in FIG.
Each of the components shown in FIG.
