2. Description of the Related Art Conventionally, a data input device having a movable mouse member has been known as a typical data input device for inputting two-dimensional coordinates. This data input device is arranged so that a ball that rotates due to friction with the table by horizontally moving a mouse member on the table two-dimensionally and a ball that comes into contact with the ball and rotates at the same time are connected to the X-axis and the Y-axis. It is composed of two rotary encoders for detecting the respective moving directions and moving amounts by their rotations, and the output thereof is converted into a pulse signal and inputted to a personal computer or the like.

[0003]

As described above, the conventional data input device having the mouse member obtains the data of the moving direction and the moving amount by detecting the rotation of the ball arranged in the mouse member. Therefore, it is essential that the ball rotates in the mouse member.

Therefore, in this conventional data input device,
(1) In order to rotate the ball in the mouse member, a table or the like having an appropriate frictional force on the surface is required, and the ball must always be in contact with the surface of the table or the like for use. The degree of freedom of movement is low, and (2) a relatively wide flat surface is required to secure a sufficient amount of movement of the mouse, and (3) frictional force between the ball inside the mouse and its moving surface is reduced. Oil, water,
There is a problem that it is not suitable for use in an environment with dust.

An object of the present invention is to provide a data input device which does not require a mechanical / physical contact of a mouse member or a plane for moving the mouse member and is also excellent in environment resistance. It is in.

According to the present invention, there is provided one vibrating gyro arranged as a detecting means for detecting a moving direction and a moving speed, and three switches for controlling the movement of the X axis and the Y axis. A movement control means which is operated by an operation; a signal conversion output means which converts the vibration gyro signal and the three switch signals into a pulse signal indicating a moving direction and a moving speed with respect to each of the X axis and the Y axis and outputs the pulse signal. A data input device is provided, which comprises a movable mouse member that houses the vibrating gyro, the movement control means, and the signal conversion output means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A data input device according to the present invention determines a moving direction by the polarity of a signal obtained by a change in angular velocity given to one vibration gyro, and extracts a change amount of an amplitude voltage within a fixed time. , The moving speed proportional to the amount of change, that is, the time width of the output pulse signal is determined.

Here, the pulse signal is output only when the permission switch is turned on, and the directionality of the X-axis and the Y-axis is determined by the left switch Y of the mouse member which can move the X-axis.
Operate by making the axis correspond to the right switch of the mouse member.
The movement is stopped by turning off the permission switch. In this way, by operating the right / left switch with the permission switch turned off, the same function as the conventional right / left switch of the mouse member can be obtained.

Therefore, according to the data input device of the present invention, while the mouse member is held in the air, the wrist switch is turned by turning the permission switch on the right or left while increasing or decreasing the strength. The amount of change in the angular velocity is obtained from the signal polarity and the amount of amplitude, and is converted into a pulse signal corresponding to the left, right, up and down moving directions and moving speeds by turning the X-axis left switch or Y-axis right switch on and off. Is output.
