JPH10320097A - Plane coordinate-ten key input device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a small-sized and light-weight plane coordinate-ten key input device convenient for carrying by performing the switching operation of coordinate input and ten key input by turning a second switch ON and OFF. SOLUTION: A first button and a second button corresponding to the respective switches of a first switch 3 and the second switch 4 are incorporated. The coordinate input inputted to a plane coordinate-ten key input part 2 is inputted to an A/D conversion circuit 16, converted to a digital signal and converted to a coordinate value for a mouse by a main processor (CPU) 11. Then, the coordinate value for the mouse is outputted from output 18 to a personal computer by a connection cable 6 through a serial interface(SI) 15. When the second switch 4 is pressed and turned ON, the CPU 11 handles the coordinate input of the plane coordinate-ten key input part 2 as the ten key input, converts it to a ten key signal and outputs the ten key signal from the output 18 to the personal computer by the connection cable through the SI 15.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a mouse interface (AD) for an APPLE machine of a personal computer.
The present invention relates to a plane coordinate / numeric keypad input device for inputting coordinates in B).

[0002] In recent years, personal computers have been widely used. In order to use a personal computer, it is necessary for an operator to input data using a coordinate input device.

[0003]

2. Description of the Related Art Conventionally, a mouse, a plane coordinate input device, and the like have been used as a coordinate input device in a personal computer. However, the downsizing of personal computers and the shift to notebook computers and sub-notebook computers have also reduced the size of keyboards and the like, eliminating the need for numeric keys for numeric input, and reducing the use of numerics when using software such as spreadsheets. I had to put up with the inconvenience of typing.

[0004] Further, although a numeric keypad that can be used for a notebook personal computer, a sub-notebook personal computer and the like is sold, the numeric keypad has a large shape and is not suitable for carrying. The interface was also for RS-232C, and there was a problem that it could not be used as a modem or the like.

[0005]

There is a numeric keypad which can be used in a conventional notebook personal computer, sub-notebook personal computer, and the like, but the shape is large and not suitable for carrying. In addition, when a modem or the like is used, there is a problem that it cannot be used because of an RS-232C interface.

Accordingly, it is an object of the present invention to provide a plane coordinate / numeric keypad input device which is small, light and convenient to carry.

Another object of the present invention is to use a mouse interface (ADB) to switch between coordinate input and numeric keypad input without using the RS-232C interface used by a modem or the like, and to use plane coordinates and coordinates. A ten-key input device is provided.

[0008]

To achieve this object, the present invention provides a plane coordinate / numeric keypad input device which is provided with a mouse interface of an APPLE machine and a numeric keypad interface of an APPLE machine in advance, and a coordinate input unit. A coordinate value corresponding to each switch of the numeric keypad is assigned, and an operation of switching between coordinate input and numeric keypad input is performed by turning on and off the second switch.
