Abstract

PURPOSE:To draw an oblique line, etc. at an optional angle, and also, to output a pseudo pulse of an optional line kind, by constituting the titled device so that an optional output signal can be sent to a host side by a pseudo pulse generating circuit which is contained in a mouse, by selecting an external switch. CONSTITUTION:When even one of an angle volume 2 and a line kind volume 3 is turned on, an output signal of a horizontal direction sensor 8 is inhibited, instead of which an output signal of a vertical direction sensor 6 and a signal which is generated by a pseudo pulse generating circuit 9 are outputted to a host, by which an optional angle, and a line kind (a dotted line, a one point chain line, etc.) are obtained. An angle adjusting input 11 is a signal for correcting a fact that an angle is changed by an aspect ratio of a screen of a display to be used. In such a way, since the pseudo pulse generating circuit is provided, this device can be operated even on an application which is not supported by a software.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention and Field of Industrial Application] This invention can easily be applied to computer
The present invention relates to a mouse input device for [)esign].

[Prior Art] Fig. 3 is an electrical connection diagram showing a conventional mouse input device. In the figure, (4) is a metal ball, and (5) is a metal ball (4).
), the vertical roller (6) is in contact with the vertical roller (5)
(7) is a horizontal roller that is 90' apart from the vertical roller (5) and contacts the metal ball (4); (8) is a horizontal sensor that detects the rotation amount of the horizontal roller (7). This is a lateral sensor for detection.

Next, the operation will be explained. When the metal ball (4) rotates, the vertical roller (5) changes depending on the direction and amount of rotation.
, the horizontal rollers (7) rotate together, and the vertical and horizontal movement amounts accompanying the rotation are detected by the vertical sensor (6) and the horizontal sensor (8), and are directly converted into electrical pulses to a host (not shown). (personal computer, etc.).

[Problems to be solved by the invention] Conventional mouse input devices are configured as described above, so they simply transmit signals to the host, and the software handles straight lines, diagonal lines, and line types. have to,
Software development becomes complicated and line type functions are not supported in many cases. In addition, although it is possible to draw diagonal lines, it does not use an angle specification method, which causes problems such as inconvenience when used for CAD, such as selecting the line type once by inputting from a keyboard.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a mouse input device that can draw diagonal lines at any angle and output pseudo pulses of any line type.

[Means for Solving the Problems] The mouse input device according to the present invention makes it possible to send any output signal to the host side using a pseudo pulse generation circuit built into the mouse by selecting an external switch. It is.

[Operation] The pseudo pulse generation circuit according to the present invention outputs an arbitrary signal to the host side based on the output signal of either the vertical sensor or the horizontal sensor.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
In the figure, (1) is the mouse body, (2) is an angle volume as an angle selection switch, and (3) is a line type volume as a line type selection switch.

FIG. 2 shows an internal electrical connection diagram of the mouse body (1) in which the same parts as in FIG. 3 are given the same symbols,
In FIG. 2, (9) is a pseudo pulse generation circuit, (10
) is an output control circuit configured by a combination of various gates.

Next, the operation of the above embodiment will be explained. When the angle adjuster (2) and line type adjuster (3) are OFF, the output control circuit (10) transmits the output signals of the vertical sensor (6) and horizontal sensor (8) as they are to the host side. , which operates similarly to a conventional mouse input device.

When either the angle adjuster (2) or the line type adjuster (3) is turned ON, the output signal of the horizontal direction sensor (8) is suppressed, and the output signal of the vertical direction sensor (6) and the pseudo pulse generation circuit are suppressed instead. By outputting the signal created in (9) to the host, any angle or line type (dotted line, dashed line, etc.) is determined.

The angle adjustment input (11) is a signal for correcting changes in angle due to the aspect ratio of the screen of the display used.

Note that in the above embodiment, a case was explained in which vertical and horizontal signals are output using a vertical signal as the basis of the output signal, but even if the signal is created based on a horizontal signal, the same effect as in the above embodiment can be achieved. .

Furthermore, although the angle and line type are used as output conditions in the above embodiments, the pseudo pulse generation circuit may be controlled using other output conditions.

[Effects of the Invention] As described above, according to the present invention, since the pseudo pulse generation circuit is provided, it can be operated even on applications that are not supported by software. In addition, it is possible to reduce the amount of development required for software that will be supported in the future.
