Abstract

PROBLEM TO BE SOLVED: To improve the working efficiency when plural persons process the same screen by means of plural mice. SOLUTION: The two-phase signal relating to the X axis direction of a mouse 1 is inputted to a phase discrimination circuit 14a where the signals representing the moving direction and the movement amount of the mouse 1 are outputted. In the same way, a phase discrimination circuit 14b outputs the signals representing the moving direction and the movement amount of a mouse 2. A count-up pulse addition circuit 15a adds together the (f) direction movement amounts of both mice 1 and 2, and a count-down pulse addition circuit 15b adds together the movement amounts of both mice of a single direction. These added movement amounts are increased and decreased by an up-dot counter 16a, and the output of the counter 16a is taken out. Then a mouse signal generation circuit 17a outputs an A-phase signal TXA and a B-phase signal TXB of the X axis direction, respectively. In the same way, the signal processing of the Y axis direction is carried out in a Y axis addition circuit 12 and an A-phase signal TYA and a B-phase signal TYB are outputted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to position information transmission of a mouse used as a pointing device such as an OA device equipped with a mouse interface, and more particularly, to a single OA device from a plurality of mice. It relates to position information transmission of a mouse when a signal is input.

[0002]

2. Description of the Related Art Many OA devices such as personal computers and EWSs are equipped with a mouse interface as standard equipment. By moving a connected mouse, an arrow indicating the current position on the display, etc. Can be moved, and this movement can be combined with the pressing of a switch on the mouse to draw a drawing or select a menu screen. FIG.
Figure 2 shows the schematic diagram of the mouse. The mouse 1 includes a switch 3 for the right button and a switch 4 for the left button, a freely rotating ball 5, and a rotary encoder for the X axis for detecting the amount of movement of the mouse in the X axis direction (horizontal direction). It is composed of a coder 6 and a Y-axis rotary encoder 7 for detecting the amount of movement in the Y-axis direction (vertical direction). If you move this mouse to the right (left) in the X-axis direction, the arrow on the display moves to the right (left) in the horizontal direction, and if you move it to the top (down) in the Y-axis direction, the arrow on the display moves. Vertical top (bottom)
Move to.

The movement of the arrow on the display due to the movement of the mouse will be described below in the X-axis direction.
The rotary encoder herein will be described as the most commonly used optical two-phase rotary encoder. FIG. 9 shows the ball 5 in FIG. 8 and the rotary for X-axis.
The schematic of the encoder 6 is shown. In the figure, an X-axis rotary encoder 6 includes a cylindrical shaft 61 which is in contact with the ball 5, a rotary disk 62 having a large number of slits formed therein, and a light emitting diode 63. , Light receiving element 64
And a Schmitt trigger 65. The light emitting diode 63, the light receiving element 64, and the Schmitt trigger 65 are arranged in two sets in order to generate two-phase signals having different phases. The light emitted from the light emitting diode 63 passes through the slit of the rotating disk to receive the light receiving element 6.
4, the slits are formed at equal intervals, and when the shaft 61 is rotated, the rotary disk 62 is also rotated, and the light from the light emitting diode 63 to the light receiving element 64 is repeatedly transmitted / blocked.

The outputs of the two light receiving elements 64 are Schmidt
The waveform is shaped by the trigger 65 and becomes digital encoder output waveforms A phase and B phase as shown in FIG. The shaft 61 and the rotating disk 62 are connected to the light emitting diode 6
When rotated clockwise when viewed from 3, the phase of the A-phase signal leads the B-phase signal by 90 ° (Fig. 10 (a)), and when rotated counterclockwise, the phase of the A-phase signal is reversed. 2 are arranged 90 ° behind the B-phase signal (FIG. 10B), and two sets of light-emitting diodes 63 and light-receiving elements 64 for A-phase and B-phase are arranged. Regarding the movement of the mouse in the left-right direction, if the movement to the right is the + direction and the movement to the left is the-direction, the A-phase signal will be generated when the mouse is moved to the right (+ direction) due to the arrangement of each element. When the signal moves ahead of the B-phase signal by 90 ° and moves to the left (-direction), the A-phase signal is output after being delayed by 90 ° from the B-phase signal.

In the mouse interface section in the personal computer connected to the mouse, the A phase and B phase signals are input, and the moving direction of the mouse is moved by the phase difference between the two signal waveforms and the number of pulses of both signals. The amount is detected and the arrow indicating the current position on the display is moved.

Similarly in the Y-axis direction, two sets of light-emitting diodes for A-phase and B-phase, a light-receiving element and a Schmitt trigger are arranged in the rotary encoder 7 for Y-axis. Move the arrow on the display up or down as you move.

[0007]

In the conventional mouse-computer interface as described above, it is relatively easy for the mouse user to move the arrow on the screen to a desired position. is there. However, since only one mouse can be connected to the personal computer, when the same image is created and processed by a plurality of people, the mouse user (operator) can change the position of the arrow shown on the screen. If there is a deviation from the intended position of a person other than the mouse user, it is necessary to verbally inform the mouse user of the desired position and move the arrow to the position as instructed. There is a problem in that it takes time to communicate, and it takes time for a person other than the mouse user to temporarily carry and operate the mouse, resulting in poor efficiency.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a mouse adder capable of improving work efficiency when a plurality of persons use a mouse to process the same screen. I am trying.

[0009]

In order to achieve the above object, a mouse adder of the present invention inputs signals from a plurality of mice, converts each input signal into a signal representing a moving direction and a moving amount of the mouse, It is characterized in that the moving amount is added for each moving direction for a plurality of mice, and a signal of the same type as the signal from the mouse is generated and output based on the added moving direction and moving amount.

By connecting a plurality of mice to an OA device or the like via the mouse adder of the present invention, each of the plurality of mice can be individually used as a pointing device. Furthermore, if you move multiple mice at the same time,
Since the moving amount can be added and output for each moving direction of each mouse, work efficiency is improved.

In order to determine that, n-stage connection is used here.

If any one of 1XCUP, 2XCUP and XCUP-CRR is "H", TXCUP outputs "H" in synchronization with CLK. 1X CUP and 2X
When CUP becomes “H” at the same time, the value to be reserved is counted up to the up / down counter 21, and 1XCU is set.
