Abstract

PURPOSE:To obtain the shift value data equivalent to that obtained by shifting a mouse device in a wide range by delivering repetitively the shift value data for each sampling time and extracting this data with operation of a changeover switch part after converting it into an optional multiple one. CONSTITUTION:When a mouse device is moved on a plane, a shift value of the X and Y direction shift values and these values are measured by a detecting part 1 for each time interval supplied from a sampling timer part 2. These measured shift values are supplied to a repeating part 5 and a gate part 7. The part 5 stores the received measure value and delivers it repetitively and synchronously with the detecting time interval signal. This repetitively delivered shift values are supplied to a magnification setting part 8 and added together repetitively to be equal to the set magnification. This added value is outputted as the multiplied shift value data. The part 7 applies the multiplied shift value data to a data format part 3 when a changeover switch part 6 is pushed. While the actual shift value data is applied to the part 3 when the part 6 is not pushed.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a mouse device for moving a pointer, cursor mark, etc. on a display screen of a personal computer or the like in any direction.

[Conventional technology]

A conventional mouse device is constructed as shown in FIG. The movement amount detection unit 1 dynamically detects the movement amount of the mouse device in the plane X and Y directions from the rotation of the ball and outputs it as a count value, and the sampling timer unit 2 sets the interval of detection time of the movement amount. do. The data formatter section 3 is provided with time interval data and movement amount count value data, formats the data in a fixed data format, and outputs the data. A general purpose switch section 4 is also provided which is used for various purposes.

The amount of movement of the mouse device in the vertical and horizontal directions (X, Y) is counted at predetermined time intervals, and the counted value data is used together with the output data of the general-purpose switch unit 4, for example, as shown in FIG. It is output as 24-bit serial data.

[Problems to be Solved by the Invention] With conventional mouse devices, when it is desired to move a cursor or the like over a wide range on a display screen, the mouse device must necessarily be moved a large distance on a table. There wasn't. Since it is not possible to move the mouse device greatly on a narrow table or a table whose movement area is narrowed by a notebook, etc., after moving the mouse device - times, quickly lift the mouse device and set the general-purpose switch unit so that the movement amount detection unit 1 does not operate. 4, I had to return it to the starting position and move it in the same direction as last time. Sometimes, it is inconvenient that such a troublesome repetitive operation has to be performed two or three times.

This invention was made in view of the above circumstances, and an object of the present invention is to provide a mouse device that can move a cursor, etc. over a wide range as necessary, even if the amount of movement of the mouse device is small. .

[Means for solving problems]

In a mouse device such as a personal computer that moves a cursor or the like on a display screen, there is a movement amount detection section 1 that detects the movement amount and outputs actual movement amount data, and a movement amount detection section 1 that sets the interval of detection time of the movement amount and outputs a sampling time signal. a sampling timer section 2 that outputs the actual movement amount data, a repeat section 5 that inputs and stores the actual movement amount data, and repeatedly outputs the stored movement amount data in synchronization with the sampling time signal; a magnification setting section 8 which inputs output movement amount data and outputs doubled movement amount data; a gate section 7 to which the doubled movement amount data and the actual movement amount data are given; and this gate section 7. and a change-over switch section 6 that controls and outputs either the doubled movement amount data or the actual movement amount data.

[Effect]

To explain the operation of the present invention, the moving amount data of the mouse device counted by the moving amount detecting section 1 within the sampling time set by the sampling timer section 2 is collected by the repeating section 5.
is input and stored. The repeat ss repeatedly outputs this movement amount data at each sampling time, and the magnification setting section 8 converts this data to an arbitrary magnification. By operating the changeover switch section 6 and taking out the movement amount data converted to an arbitrary multiple from the gate section 7, it is possible to obtain movement amount data equivalent to when the mouse device is moved over a wide range on a plane.

〔Example〕

FIG. 1 is a block diagram of a mouse device connected to a word processor, personal computer, etc., and shows a first embodiment of the present invention. Reference numeral 1 denotes a movement amount detection unit that detects the movement amount of the mouse device, and the movement amount detection unit 1 mechanically detects the movement amount in the vertical and horizontal directions (X, Y) on the table from the rotation of the ball. It outputs count value data. The sampling timer section 2 sets the time interval of the detection time and the sampling time, and supplies it to the movement amount detection section 1, and one section of movement amount is detected during this sampling time. That is, the amount of movement of the mouse device within this time is detected as the amount of movement data created by -iM.

The movement amount data and the sampling time signal are given to the repeat section 5, and the repeat section 5 stores this movement amount data and repeatedly outputs the stored movement amount data to the magnification setting section 8 in synchronization with the sampling time signal. It is something to do. A sampling time signal is given to the magnification setting unit 8, and the movement amount data repeatedly output from the repeat unit 5 is superimposed and taken in, and the movement amount data is multiplied several times. The movement amount data multiplied by 1 is applied to one input terminal of the gate section 7. Actual movement amount data is directly given to the other input terminal of the gate section 7 from the movement amount detection section 1.

Therefore, one fixed contact A of the push button type changeover switch section 6
is connected to the reset terminal of the repeat section 5, and the other fixed contact B is connected to the control terminal of the gate section 7. The movable contact of the changeover switch section 6 is grounded, and when the push button is not pressed, the fixed contact A is connected, and when the push button is pressed, the fixed contact B is connected.
is grounded.

The movement amount data selected by the gate section 7, the sampling time signal from the sampling timer section 2, and the output data from the general-purpose switch section 4 are provided to the data formatter section 3. The data formatter section 3 outputs 24-bit serial data shown in FIG. 4 from these data. In this 24-bit data, the 8 bits on the MSB side represent the input signal from the general-purpose switch unit 4, the middle 8 bits represent the movement amount data in the left/right (X) direction, and the 8 bits on the ir and ss sides represent the movement amount data in the up/down (Y) direction. It shows the movement amount data of 2
The 4-bit data represents the movement amount data of the mouse device for each sampling time.

Next, the operation of the first embodiment will be explained.

First, when the mouse device is moved on a flat surface such as a table, the amount of movement in the X and Y directions is counted and outputted from the sampling timer section 2 at each time interval from the movement amount detection section 1. This count value data is input to the repeat section 5 and gate section 7.

Here, the repeat section 5 stores this count value, repeats it in synchronization with the detection time interval signal, and outputs the count value part, ie, movement amount data. This repeatedly output movement amount data is input to the magnification setting section 8, and at that time, it is repeatedly added and taken in so as to reach the set magnification, and as a result, the multiplied movement amount data is output.

Here, when the push button of the changeover switch section 6 is pressed,
The gate section 7 selects this multiplied movement amount data and supplies it to the data formatter section 3. Then, the data formatter section 3 formats the movement amount data and the output of the general-purpose switch section 4 into the output data format shown in FIG. 4, and outputs the data.

On the other hand, when the changeover switch section 6 is not pressed, the repeat section 5 is reset and the movement amount "0" is repeatedly output, and the gate section 7 transfers the actual movement amount data from the movement amount detection section 1 to the data formatter section 3. give to

In this way, while the push button of the changeover switch section 6 is pressed, the actual movement range of the mouse device is limited to a certain limit, and even if it cannot be moved any further, the output from the data formatting section 3 is A data output containing large movement amount data as if the mouse device had moved over a wide range can be obtained.

Next, FIG. 2 is a diagram showing a second embodiment of the present invention. In this second embodiment, a single switch/gate section 9 is used instead of the independent changeover switch section 6 and gate section 7 of the first embodiment.
has been established. The movement amount data output from the striking and movement amount detection section 1 is sent to one input terminal of the switch/gate section 9, and the multiplied and multiplied movement amount data from the magnification setting section 8 is sent to the other input end. are given to each. When the switch of the switch/gate section 9 is not pressed, the actual movement amount data from the movement amount detection section 1 is selected, and when the switch is pressed, the multiplied movement amount data from the magnification setting section 8 is output. . The other configurations and operations are almost the same as in the first embodiment.

〔Effect of the invention〕

As explained above, according to the present invention, even if a large amount of movement is actually required, the movement operation of the mouse device may be small (i.e., the cursor, etc. can be freely moved over a wide range on the display screen). Therefore, it is possible to provide a mouse device with extremely excellent operability.
