Description

[Detailed Description of the Invention] [Field of Application of the Invention] This invention relates to an input device, and more specifically, it uses a position information signal output from a position information detection means called a mouse to move a cursor on a personal computer, etc. The present invention relates to an input device that is controlled.

[Technical background of the invention] When detecting the amount of movement in the X-axis and Y-axis directions using a mouse and controlling the cursor according to the amount of movement, conventionally, the mouse uses an X-position detection sensor and a Y-position detection sensor. After appropriately amplifying the output pulse signals, the encoder and controller calculate the amount of movement in each axis direction from these signals and send them to the CPU. however,
According to this, it is inconvenient that a microcomputer or the like must be used for the encoding section and the control section, and that it cannot be used unless dedicated software is prepared.

[Purpose of the invention] This invention was devised in view of the above-mentioned drawbacks of the prior art, and its purpose is to provide an input device that has a simple circuit configuration and is easy to program software.

[Example] Hereinafter, this invention will be described in detail with reference to an example shown in the accompanying drawings.

FIG. 1 shows a schematic configuration of a position information detecting means called a mouse used in this input device. That is, this position information detection means 1 has a spherical body 2 that is rotatably held by a holding member (not shown), and an X position detection sensor 3a and an The Y position detection sensor 3b is provided so as to be in contact with each other. Each of these detection sensors 3a, 3b consists of slit plates 4a, 4b provided to follow the circular sphere 2, and a pair of light emitting units disposed oppositely with the slit plates 4a, 4b in between. and a photo sensor 5a including a light receiving section (both not shown),
5b, slit plates 4a, 4b
As the photo sensors 5a and 5b rotate, pulse signals are output from the photo sensors 5a and 5b.

Moreover, the rotation shaft 6a of each slit plate 4a, 4b,
6b, an X-axis rotational direction detection sensor 7a and a Y-axis rotational direction detection sensor 7b, which detect the rotational direction thereof, are operatively connected.

FIG. 2 shows a circuit diagram of this input device. According to this, a first one-shot timer circuit 8a is connected to the X position detection sensor 3a, which receives a pulse signal from the sensor 3a and outputs an X-direction control pulse having a constant pulse width. Similarly, a second one-shot timer circuit 8b is connected to the Y position detection sensor 3b, which receives a pulse signal from the sensor 3b and outputs a Y-direction control pulse having a constant pulse width.

This input device has four cursor movement keys provided on the keyboard, namely, an upward movement key 9a, a downward movement key 9b, a right movement key 9c, and a left movement key 9d. For example, four switches 11a to 11d are connected to each other via the connector member 10, and the output side of the first one-shot timer circuit 8a receives a signal from the X-axis rotation direction detection sensor 7a. , a first output switching circuit 12a is connected which switches the input destination of the X-direction control pulse by closing one of the two switches 11c and 11d corresponding to the rightward movement key 9c and the leftward movement key 9d. Similarly, the above-mentioned Y
A second switch which closes either of the two switches 11a, 11b corresponding to the upward movement key 9a and the downward movement key 9b in response to a signal from the shaft rotation direction detection sensor 7b to switch the input destination of the Y-direction control pulses. An output switching circuit 12a is connected thereto.

[Effects] Therefore, according to this invention, an input device with a simple circuit configuration is provided that can be used in place of a cursor key regardless of the model of the device as long as it has a keyboard. In that case, this input device makes it possible to directly move the cursor key diagonally. Further, it has the advantage that it can be used as is with conventional software on a screen editor such as Basic.
