BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data input device used as an input device for personal computers and video game machines.

[0002]

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 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 in time is reduced, (2) a relatively wide flat surface is required to secure a sufficient movement amount of the mouse member, and (3) between the ball in the mouse member and its moving surface. There is a problem that it is suitable for use in an environment with oil, water, dust, etc. that causes a reduction in frictional force.

An object of the present invention is to provide a data input device which does not require a flat surface to secure a sufficient amount of movement of the mouse member and has excellent environmental resistance.

[0006]

According to the present invention, a transmitter and a receiver are provided inside a movable mouse member, and the transmitter has a movement direction and a movement with respect to each of an X axis and a Y axis. Two vibrating gyros arranged as detecting means for detecting the speed, signal converting means for converting the signal obtained by the detecting means into digital data, and digital data converted by the signal converting means A receiver for receiving a radio wave from the transmitter, and a digital data received by the receiver for indicating a moving direction and a moving speed. It is possible to obtain a data input device characterized in that it has an output means for converting into and outputting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A data input device according to the present invention is composed of a transmitter and a receiver, and two vibrating gyros for X axis and Y axis are used as a transmitter so that they are orthogonal to each other. The movement direction and movement speed are determined from the polarities and vibration amounts obtained from the angular velocity given to each vibrating gyro, and these values are converted into digital data corresponding to the values by the signal conversion means. Then, while the data is transmitted by radio wave by the transmitting means, the receiver side receives digital data from the transmitter by the receiving means, and the received digital data is moved by the output means in the moving direction and the moving direction. It is converted to a speed signal and output.

Therefore, according to the data input device of the present invention, the angular velocity, that is, the rotation is given in an arbitrary direction of the X-axis or the Y-axis while the mouse is held in the air, apart from the personal computer or the like. As a result, the moving speed and moving direction are determined, and external output is performed.
