Abstract

PURPOSE:To facilitate an operation by outputting continuously speed information or acceleration information containing direction information obtained from latest X information and Y information outputted from a mechanism part in accordance with the operation of a switch. CONSTITUTION:When a switch 1 is operated in the course of bringing a pointing device during a moving operation, speed information containing direction information or acceleration information containing direction information at the time point of its operation is read out of a memory 17, and after its time point, and said information is outputted continuously to a host computer 4 side from a control circuit 16, until a switch 2 is operated. Accordingly, until the switch 2 is operated after the switch 1 is operated, even if the pointing device is stopped or returned to its original position, moving information is transmitted to a host computer from the pointing device, as if the pointing device is moving continuously at the same speed or acceleration as the time point of an operation of the switch 1, and displayed on a CRT display. In such a way, an operator can set freely a large position coordinate in a small moving range.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pointing device for manually using coordinate data.

[Prior Art] FIG. 6 shows a typical example of the use of this type of device, commonly referred to as a mouse or mouse device. As shown in this figure,
Pointing device (mouse) 1 is key 1-2
Alternatively, it is electrically connected 11 to the boss 1 to the computer 4 via the CRT display 3 or by direct connection. In Part 1, the movement of Tehiis 1 is displayed in real time on Display 3.

Figure 7 shows this J: Tuna conventional bonding device 1
An example of a schematic configuration is shown below. Here, 11 is a mechanism section that detects the physical movement direction using rollers or the like and outputs information on the X direction and the Y direction. 12 is the X output from the mechanism section 11
Information 13 is Y information output from the mechanism section 1lh). 14 is an interface for input/output to the host computer 4, or is this interface 1
Some devices do not have 4. 15 is an output signal, which is an information signal having the same content as the X information 12 and X information 13 from the mechanism section 11.

In the conventional device of this kind, as a means of transmitting movement information of the pointing device 1 to the host computer 4 side, the amount of hypermotion in the X direction and the Y direction mechanically detected by the mechanism section 11 is transmitted for each unit length. The signal is output in sections. That is, generally the pointing device l
The output signal 15 indicates the amount of movement in the Y direction and the X direction at intervals of output pulses (or switch information) of the X and Y output signals, respectively.

[Problem to be Solved by the Invention] However, with such a conventional device, when you want to move around in a jerky manner, you physically go beyond the table for the pointing device. Lift it up once and return it to the opposite position,
Furthermore, it requires a cumbersome operation procedure to move in the same direction as before. Further, even if a large table is used, the amount of movement of the pointing device in the same direction becomes significantly large, which is a burden on the operator.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a pointing device that can eliminate the above-mentioned drawbacks, reduce the actual amount of movement, and significantly reduce operator fatigue.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a mechanism unit that outputs velocity information including direction information or acceleration information including direction information according to a movement operation, and a mechanism unit that outputs velocity information including direction information or acceleration information including direction information according to a movement operation. A storage means for storing the latest information, a switch means for instructing reading of the latest information from the storage means, and speed information or direction information including the latest direction information at the time of instruction from the storage means in response to an instruction from the switch means. The present invention is characterized by comprising a control means for reading acceleration information and outputting it to the outside M times until the instruction is completed.

[Function] In the present invention, speed information or acceleration information including direction information obtained from the latest X information and Y information outputted from the mechanism section in response to the switch operation is continuously outputted W, so that the Even when moving the pointing device, the desired position can be output to the host computer without actually moving the pointing device.This reduces the actual movement of the pointing device, making the operation easier and easier for the operator. It is possible to significantly reduce fatigue.

Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a schematic configuration of a pointing device according to an embodiment of the present invention. Here, 16 is a control circuit that performs a control operation to be described later, 17 is a memory, and 18 and 19 are switches. Note that this type of device is generally provided with various switches for transmitting the operator's intentions to the host computer 4 (see FIG. 6), but these switches are used for transmitting information regarding movement operations according to the present invention. Since it is unrelated, it is omitted in this explanation. However, it is possible to configure this switch so that it also serves as switches 18 and 19 in FIG.

FIG. 2 shows an example of the circuit configuration of the control circuit 16 shown in FIG. In this figure, 20 is a switch control circuit that performs control operations according to the control procedure shown in FIG. 3, which is stored in an internal ROM, and 21 is a memory interface. In this example, the X information 12 .
The latest values of the X information 13 (for example, pulse intervals, etc.) are stored as digital information in the memory 17 via the memory interface 21, and the switch 18 is closed (O
N) By operation, the stored information is processed by the variable frequency oscillator and outputted as the output signal 15. This variable frequency oscillator consists of a (pulse) oscillator 22 and a variable frequency divider 2
3, which generates speed information as an output signal 15 using digital information stored in the memory 17 as frequency division ratio information of the variable frequency divider 23. In addition, the memory 17
There is a pair of devices for X information and Y information, and similarly, the memory interface 21 and the variable frequency divider 23 are also configured for X information and Y information. Further, reference numerals 24 and 25 indicate changeover switches whose switching is controlled simultaneously by the switch control circuit 25.

Next, an example of the operation of the embodiment of the present invention shown in FIGS. 1 and 2 will be described with reference to the flowchart shown in FIG. First, after the power is turned on, when the operator moves the device (pointing device) 1 (step Sl), the changeover switches 24 and 25 are switched to the output terminal side of the mechanism section II, so as in the conventional device, The movement information 12, 13 is output from the mechanism section 11 in real time as an output signal 15 to the postcomputer 4 side (step S2). At the same time, the movement information 12.13 is stored in the memory 17 via the memory interface 21 (step S3
). The information 12.13 to be accumulated may be the minimum information (that is, the latest information) for knowing the current velocity or acceleration in the X direction and the Y direction. Further, the information to be accumulated may be raw information generated in the mechanism section 11, or may be information after being subjected to arithmetic processing in an arithmetic circuit 27, which will be described later.

At this point, when the switch 18 is turned on (closed) (step S4), the switch control circuit 20 switches the changeover switches 24 and 25 to the output terminal side of the variable frequency divider 23 and Based on the information stored in the memory 17, ignoring the human power information 12.13 from (step S5).

Alternatively, as will be described later with reference to FIG. 4, an output signal 15 having a similar acceleration is output based on the acceleration at that time. Therefore, even if the movement of the device (mechanical section) is stopped after the switch (2) is operated, movement information continues to be sent to the host computer 4 side.

This state continues until the next switch 19 is turned ON (closed), and after the ON information of the switch 1 is input manually (step S6), the process returns to step 51 for the next lateral operation of the pointing device 1. wait.

That is, in this example, when the switch (2) is operated while the pointing device 1 is being moved, the speed information including the direction information or the acceleration information including the direction information at the time of the operation is read out from the handle 17. From that point on, the signal is continuously output from the control circuit 16 to the host computer 4 until the switch (2) is operated. Therefore, even if pointing device 1 is stopped or returned to its original position after operating switch ■, until switch The boss seems to keep moving!・Computer 4
The movement information is transmitted to the CRT display 3 and displayed on the CRT display 3. Therefore, by repeatedly performing the operations described above, the operator can freely set large position coordinates within a small movement range.

FIG. 4 shows another example of the configuration of the control circuit 16 shown in FIG. In this example, X information +2. The Y information 13 is sampled in the latest constant interval, and in response to the ON operation of the switch 18, the arithmetic circuit 27 calculates 94 accelerations from the sampling information, and continuously outputs the calculated acceleration data from that point onwards. variable frequency divider 2 to output as signal 15
The frequency division ratio of 3 is determined by the arithmetic circuit 27. At the same time, the arithmetic circuit 27 switches the selector switches 24 and 25 to the variable frequency divider 23 side until the switch 19 is turned on manually. Therefore, the acceleration information continues to be output from the pointing device 1 to the host computer 4 during the period from the manual power of switch (2) to the manual power of switch (2). Note that the variable frequency divider 23 is provided separately for X information and Y information as in the case of FIG.

FIG. 5 shows the configuration of another embodiment of the present invention in which analog storage circuits are used in place of the digital storage control circuit 16 and memory 17 shown in FIG. In this example, mechanism section 1
The pulse interval of Y+r4 signal 13 output from 1 is f-V
(Frequency voltage) is converted into a DC voltage by the converter 31, and the latest speed information is always held in the analog level sampling circuit 3z, and based on the held information, the pulse interval is the same as the Y information 13. The voltage controlled oscillator 33 oscillates a pulse of
ON) operation to manual operation of switch 19,
By switching the switch 25 to the voltage controlled oscillator 33 side, the above-mentioned pulses oscillated from the voltage controlled oscillator 33 continue to be output to the host computer 4 as the output signal 15.

Also, in the case of X information 12, the configuration 34 is similar to that of X information 13.
, 35, 38, and is processed in the same manner as the X information 13 and output as an output signal 15.

In addition, switch 18 (■) and switch 19 (2) are depicted as independent switches in FIG. switch ■ information,
Switch ■ Information may be obtained sequentially. In addition, the mechanism section 11 shown in FIGS. 1, 2, 4, and 5
It goes without saying that the control circuit 16, memory 17, etc. other than the switches 18 and 19 may be built in the main body (host computer).

[Effects of the Invention] As explained above, in the present invention, the latest X information output from the mechanism section in response to the operation of the switch.

Since speed information or acceleration information including direction information obtained from This has the effect of reducing the actual hyperactivity of the pointing device, making it easier to operate, and significantly reducing operator fatigue.
