Abstract

PURPOSE:To obtain superior operability of a mouse and space saving in and the environmental resistance of a joy stick by generating the amount of travel of a cursor per unit time for an X-axis and a Y-axis in proportion to the amount of travel of a slide hole, respectively. CONSTITUTION:When the forefinger inserted to the slide hole 3 is moved, a slide hole table 12 connected to the slide hole 3 is moved horizontally as being supported with a slide hole table supporting part 13. When the slide hole table 12 is moved, a slide hole position detecting part 14 detects the amount of travel of the slide hole 3 from a neutral position for the X-axis and the Y-axis, individually, and sends the present slide hole position to a cursor travel pulse generating part 15. The cursor travel pulse generating part 15 generates a cursor travel pulse with a constant frequency per unit time having meaning to identify plus and minus directions in proportion to relative difference between the present slide hole position and the neutral position at every X-axis and Y-axis by slide hole position information sent from the slide hole position detecting part 14.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a coordinate input device, and particularly as a small coordinate input device used in a bad environment and a narrow usage space.
The present invention relates to a slide hole type coordinate input device that allows an operator to easily input coordinates.

[Conventional technology]

2. Description of the Related Art Conventional coordinate input devices that use a remote control cursor, such as a mouse or a joystick, are generally known. There are also devices that use direct contact with the screen, such as light pens and touch panels. moreover,
Coordinate input devices such as tablets and digitizers that have the functions of a mouse, a touch panel, and a light pen are also generally known.

[Problem to be solved by the invention]

The above-mentioned conventional techniques have various problems depending on each device. In other words, although mice have good operability, they have problems with environmental resistance and securing space for operation, and joysticks have good environmental resistance and space-saving properties, but are not as operable as keyboards. Light pens have the problem of being almost on the same level as cursor movement keys, light pens have good space-saving properties but have problems with errors in coordinate input, and touch panels have good operability but are difficult to input coordinates. There are problems with accuracy, and although tablets and digitizers have good operability, there are problems with environmental resistance, especially against external electromagnetic pulses, and securing space for device installation. Furthermore, with coordinate input devices other than a mouse, it is difficult to simultaneously perform a function key or a function button corresponding to a mouse click button and a cursor movement operation with one hand. In order to solve the above-mentioned problems, an object of the present invention is to provide the operability of a mouse and the space-saving and environmental resistance of a joystick.Furthermore, as for the input/output interface of a computer, it is possible to use the same interface as a mouse. By realizing the present invention, hardware and software using the present invention can be used in the same way as a mouse without being aware of the special characteristics of the present invention.

[Means to solve the problem]

In order to achieve the above object, the slide-hole type coordinate input device of the present invention has a cursor movement amount instruction function and a click button for multiple input instructions arranged in an environmentally resistant one-handed housing. In addition, the cursor movement amount instruction is
- By converting a few centimeters of movement of the slide hole by a finger into the amount of cursor movement, and further converting the converted information into the amount of cursor movement similar to that of a mouse, it is possible to modify and modify hardware and software. It is characterized by the fact that it is not necessary.

[For use]

In the present invention, when the slide hole is moved by the operator, the relative position of the slide hole from the neutral position changes the amount of cursor movement per unit time in proportion to the amount of slide hole movement on the Y axis and Y wheel separately. By generating this information, control information similar to that of a mouse is sent to the computer.

【Example】

An embodiment in which the slide hole coordinate input device of the present invention has three click buttons will be described below with reference to the drawings. FIG. 1 is a schematic external view of a slide-hole coordinate input device according to an embodiment of the present invention, and FIG. 2 is a schematic diagram of the internal structure of a slide-hole coordinate input device according to an embodiment of the present invention. As shown in FIGS. 1 and 2, the slide hole type coordinate input device of the present invention includes a housing 1, a wrist support 2, a slide hole 3, a slide hole table cover 4, a left click button 5, and a center click button. 6, right click button 7, connection cable 8, connection cable protection ring 9, click button cover 10, click button control unit 11,
It includes a slide hole table 12, a slide hole hole table support section 13, a slide hole position detection section 14, a cursor movement pulse generation section 15, and a communication control section 16. In FIG. 1, the operator places his right wrist on the wrist support part 2.
, the left click button 5 is operated with the thumb, the slide hole 3 is operated with the index finger, the center click button 6 is operated with the middle finger, and the right click button 7 is operated with the ring finger. The cursor on the screen is moved by moving the slide hole 3 back and forth and left and right with the index finger, and each click button is pressed up and down with each finger. In Fig. 2, the housing 1 is made of a hard material containing an electromagnetic resistant material, and the slide hole table cover 4, connection cable protection ring 9, and click button cover 10 are made of a soft material containing an electromagnetic resistant material. These protect each movable mechanism and circuit mechanism from external dust and electromagnetic pulses. When the operator moves his index finger inserted into the slide hole 3 back and forth and left and right, the slide hole table 12 connected to the slide hole 3 moves to the slide hole table support section 1.
It slides horizontally supported by 3. When the slide hole table 12 moves, the slide hole position detection section 14
detects the amount of movement of the slide hole 3 from the neutral position separately for the Y axis and the Y wheel, and sends the current slide hole position to the cursor movement pulse generator 15. In the cursor movement pulse generation section 15, the slide hole position detection section 1
Constant frequency per unit time that has the meaning of identifying the positive direction and negative direction proportional to the relative difference between the current slide hole position and the neutral position for each Y-axis and Y-axis based on the slide hole position information sent from 4. cursor movement pulse. That is, when the slide hole is in the neutral position, no cursor movement pulse is generated, and as the slide hole moves away from the neutral position, a higher frequency cursor movement pulse is generated. Then, the cursor movement pulse generator 15
sends the generated cursor movement pulse to the communication control section 16. When the operator operates each click button, the click button control unit 11 transmits the details of the operator's operation to the communication control unit 1.
Send to 6. The communication control section 16 sends each information sent from the cursor movement pulse generation section 15 and the click button control section 11 to the mouse interface through the emulation cable 8 and the mouse connector. The slide hole table cover 4 is made of a soft material and has a function of returning the slide hole 3 to the neutral position when the operator relaxes his index finger. In this way, we have realized a highly environmentally resistant compact coordinate input device that can be operated with one hand and has operability comparable to moving a mouse over a dozen centimeters by moving a finger from a few millimeters to a few centimeters. The software and software may be used without modification or modification.

【Effect of the invention】

The present invention maintains the space-saving properties of a joystick while determining the amount of relative movement of the cursor on the screen based on the movement position of the slide hole, bringing the operability of coordinate input closer to that of a mouse. Environmental resistance has been improved by incorporating an electromagnetic material to improve electromagnetic resistance, and by attaching a soft cover to each movable part to improve dust resistance.
This makes it possible to easily input coordinates in environments where reliability is required and space is limited, even in adverse environments.Furthermore, by making the input/output interface with a computer similar to a mouse, it can be used to easily replace existing hardware. By allowing the connection of software to a mouse connector and the connection of software to a mouse driver, the costs of hardware and software modification and modification for connection of the present invention to a computer are completely unnecessary. There is an effect that there is.
