Abstract

PURPOSE:To improve the operability and input precise position information. CONSTITUTION:When the mouse is operated, a main body 1 is held in a hand like a pen and a sensor tip part 2 is moved on a desk top. Switches 3 and 4 are pressed with the index finger or middle finger when necessary to perform pointing operation. Further, a movement quantity adjusting switch 5 is switched to set the magnifications of the movement quantity inputted to the main device to a proper value. At the part of the switch 5, X1, X2, X4, X8, X16, X12, X1/2, X1/4, X1/8, X1/16, etc., are displayed so as to indicate magnifications. Desired magnifications can be set by aligning a mark 6. The mouse for magnification setting is equipped with a movement quantity adjusting circuit, which shifts X and Y movement quantity data, obtained according to the detection results of sensors, bit by bit, according to the state of the switch 5 to obtain said magnifications.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse used as an input device for a personal computer or the like.

[0002]

2. Description of the Related Art A mouse of this type is used for moving a cursor on a screen of a personal computer or a workstation, or for pointing a specific portion on the screen. There are different types of mice, such as mechanical type, optical type, and acoustic type, depending on the movement detection method. In addition, there are various varieties in the number of pointing button switches and the interface method with the connected main device.

The basic components of such a mouse are the following four. (1) X, Y axis movement amount sensor (2) Button switch (3) Data multiplexer (4) Host interface X, Y axis movement amount data, button switch data, and mouse status data are composed of multiple bytes. , It is necessary to decompose the data into bytes and send them to the main unit. The data multiplexer is used for that purpose.

The approximate shape of the mouse is a round ellipsoid, and the dimensions are 100 mm × 60 mm × 30.
It is about mm. Then, one or a plurality of the above button switches are provided at positions that can be operated with a finger.

[0005]

When the position information is input to the main unit by the mouse, the mouse is moved on a work desk or the like. However, since the mouse is the size described above and the size of the work desk is limited, for example, when moving the cursor on the screen for a long distance, it is not possible to move the mouse once. It is necessary to repeat the operation of moving the mouse a certain distance, returning it to its original position, and moving it again. As a result, the operability of the mouse is significantly reduced.

[0006] In the case of tracing a world map to draw a free-form curve, since the position actually pointed by the mouse on the map cannot be seen, accurate pointing cannot be performed on the map. There is.

An object of the present invention is to solve the above problems and to provide a mouse which has high operability and can accurately input position information.

[0008]

The present invention relates to a mouse for inputting information relating to a position on a screen of a display device, a pen-shaped main body, and a main body provided at the tip of the main body. A sensor that detects a movement amount in the axial direction and the Y-axis direction and outputs a signal corresponding to the detected movement amount, a movement amount adjustment switch, one or more button switches, and an output signal of the sensor, First control means for generating a signal representing the amount of movement of the sensor, and processing the signal generated by the first control means, and the amount of movement represented by the signal is based on the state of the movement amount adjustment switch. It is characterized by comprising a second control means for switching and a third control means for outputting a signal representing the state of the button switch.

[0009]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 shows an example of a mouse according to the present invention. When operating this mouse, the main body 1 is held by hand like a pen and the sensor tip 2 is moved on the desk. If necessary, the switches 3 and 4 are pressed with the forefinger or the middle finger to perform pointing or the like. Furthermore, by switching the movement amount adjustment switch 5, the magnification of the movement amount input to the main device is set to an appropriate value. In order to show the magnification on the part of the switch 5, × 1, × 2, × 4, × 8, × 1
6, x1 / 2, x1 / 4, x1 / 8, x1 / 16, etc. are written, and the desired magnification is set by aligning them with the mark 6. The mouse body 1 is connected to a main device (not shown) by a cable 7.

The electrical configuration of this mouse is as shown in FIG. The mouse is roughly divided into a sensor unit 11 including a movement amount sensor and a switch, and a sensor unit 1.
A controller 12 that secures and shapes the data from 1.
It is divided into an interface 13 with a host system (main device) 14 that uses data from a mouse for an application.

The sensor unit 11 includes an X-axis sensor 21 for detecting the amount of movement of the sensor tip 2 in the X-axis direction, a Y-axis sensor 22 for detecting the amount of movement of the sensor tip 2 in the Y-axis, and a host system. It is composed of a moving amount adjusting switch 5 for adjusting the moving amount of the mouse given to 14, and switches 3 and 4. Then, the X-axis sensor 12 and the Y-axis sensor 22 output to the control unit 12 two-phase pulse signals corresponding to the detected movement amounts in the X-axis direction and the Y-axis direction, respectively.

The X-axis counter 26 and the Y-axis counter 27 of the control unit 12 receive the two-phase pulse signals from the X-axis sensor 21 and the Y-axis sensor 22, respectively, count the number of pulses, and count the counting results in the X-axis direction and the Y-axis direction. Output as axial movement data. The movement amount adjusting circuit 28 multiplies these movement amount data by a number according to the state of the switch 5 and outputs the final movement amount data. Specifically, the adjustment circuit 28 controls the counter 26, depending on the state of the switch 5.
By bit shifting the data from 27,
4, 8 times, or 1/2, 1/4, 1/8 times. The multiplexer 29 has a movement amount adjusting circuit 28.
The movement amount data in the X-axis direction and the Y-axis direction and the data indicating the states of the switches 3 and 4 received from are switched and output, and the interface 13 sends the data to the host system 14.

The format of the data sent from the multiplexer 29 to the host system 14 via the interface 13 is kept compatible by matching the data format of the mouse conventionally used in each host system. The mouse of this embodiment can be connected without changing the application of the host system.

The controller 12 and the interface 13 do not necessarily have to be incorporated in the mouse body 1, but may be separately provided and connected to the body 1 by a cable.

[0015]

As described above, the mouse of the present invention has a pen-shaped main body, and the main body can be held by hand, and the sensor at the tip of the mouse can be moved on a desk or the like. It is easy and can be moved subtly and accurately using your fingertips. Further, since it is possible to visually recognize which position the sensor is pointing to, it is possible to easily trace a map or the like. Furthermore, since the output movement amount can be switched with the movement amount adjustment switch, for example, when the switch is set to output a large movement amount, a single movement of the mouse is sufficient. Can be input to the main unit. Therefore, for example, when moving the cursor on the screen for a long distance, even if the mouse can be moved only within a narrow range, it is not necessary to operate the mouse many times as in the conventional case, and only one operation is required, and the wrist It is enough to operate further.
