Abstract

PURPOSE:To increase the analyzing speed through a computer by inputting the external analog information to shift a cursor and a stylus pen to X and Y directions via the 1st and 2nd controllers then detecting a contact position of the stylus pen on a magnetostrictive plate. CONSTITUTION:A stylus pen 2 can be moved toward a Y direction on a cursor 3 which is moved toward an X axis. Then the analog information given from input ports 4 and 5 are supplied to the drive means of the cursor 3 and the pen 2 via the 1st and 2nd controllers respectively. Then the pen 2 has a contact onto a magnetostrictive plate 1 to which many pieces of position information on X and Y axis directions are allocated in a matrix form. This contact position of the pen 2 is detected and outputted in the form of the digital values on both X and Y axes. Thus it is possible to obtain the correlated digital information before it is inputted to a computer.

Description

Detailed Description of the Invention A9 Object of the Invention - The present invention relates to an analog-to-digital conversion device, and in particular -
The present invention also relates to an interface suitable for inputting analog information into an analysis computer.

Conventionally, in order to input analog information to an analysis computer, each piece of information had to be individually A/D converted and input.
It was necessary to reassemble the correlations between individual pieces of information inside the computer and then analyze it.

The present invention seeks to provide a device that can obtain correlated digital information before inputting it into a computer.

Ω0 Structure of the Invention The analog-to-digital converter of the present invention comprises a magnetostrictive plate to which a large number of positional information on the X and Y axes is assigned as digital values, and a stylus pen is moved in the X direction KfI! on this magnetostrictive plate. A cursor and a cursor drive means, a stylus pen that moves in the Y direction with the cursor, a stylus pen drive means, detects the contact position of the stylus bar on the magnetostrictive plate, and converts the position to the X direction.
It is equipped with a detection means that outputs digital values on the axes and on the is input, and the stylus pen driving means is operated according to the input value via the second controller.According to the structure described above, the input analog information is output as a digital signal. In addition, if two analog information have a correlation, it is converted into a signal in the form of a plane surrounded by a certain X-axis and a Y-axis (or a point) that falls within a certain area in a steady state and deviates in an abnormal state. Even when inputting analog information, it is possible to determine whether it falls within a certain range before inputting it to the computer 1. This allows the computer 1 to speed up analysis operations.

20 Practical Examples of the Invention The present invention will be described in detail with reference to FIG. 1, which shows a plan view and a side view of the apparatus of this embodiment. The magnetostrictive plate 1 attached to the surface of the main body is arranged in a square shape to which a large number of positional information in the X-axis and Y-axis directions are assigned.The position of the stylus pen 2 that is in contact with the rear surface of the plate is digital information It is now detected.

The stylus pen 2 moves in the Y-axis direction with a cursor 3, the cursor 3 moves in the X-axis direction, and the stylus pen 2 moves in the Y-axis direction with a cursor 3, and
A moving means and four cursor driving means are provided inside the main body. On the other hand, an analog information input port 4.5 is provided, and a first controller and a second controller are interposed between the input port number 5 and the cursor drive means and stylus pen drive means, The cursor and stylus pen are moved in the χ-Y direction according to the input value of external analog information. In addition, 6.7 is the X-axis and Y-axis sensitivity switch 8.9 is 7 analog meters of input information, and 10
is an output port for connecting to an analysis computer. It is also provided with a clock signal changeover switch 11, so that when inputting l analog information, the clock signal can be selected as appropriate.

t1 Effects of the Invention According to the present invention, since the correlation of seven, two or more pieces of analog information can be obtained as a digital signal, there is an effect that the analysis operation by the computer I can be carried out quickly.
