Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a positional information input device that is effective when used to input handwritten figures drawn two-dimensionally on an operation panel into a computer online. .

Conventional technology Conventionally, the movement of a sphere attached to an object that moves on a flat surface due to manual operation is converted into a signal to obtain position information of the object, and the position information is input into a computer etc. through a code etc. The devices illustrated in FIGS. 9 and 10 are considered. To explain this, FIG. 9 is a partially cutaway plan view of a conventional position information input device, and FIG. 10 is a partially cutaway side view thereof. In those drawings, 1
is a housing that can be held in place and is divided into upper and lower parts. An iron sphere 2 is housed inside it so that it can roll, and the lower part of the sword/tsuno sphere 2 is in the housing 1.
It protrudes downward from an opening 3 provided at the bottom of the plate and comes into contact with a mounting plane 4. Further, the housing 1
is movably supported on the mounting plane 4 by the spherical body 2 and a plurality of balls 5 which are rotatably provided on the bottom surface of the housing 1. The sphere 2 has two rotational axes ea and eb at right angles to the housing 1, and a rotational axis 6m+6b.
The horizontal position is regulated by an elastic biasing body 7 installed at an equiangular position in between, and the vertical position is regulated by being housed in a case 8 fixed to the nozzle 1. ing.

are connected by solder.

MfJ pre-printed board 11 Oa position information detection section 9
1L.

A circuit for converting the positional information detected by 9b into a signal corresponding to the detected value is provided, and is connected to the input section of the computer through a cord 12.

Next, the operation of this conventional example will be explained.

First, when the input operator holds the housing 1 in his hands and moves it on the mounting plane 4, the sphere 2 also rolls on the mounting plane 4 as the housing 1 moves. Then, the rotating shaft 616b in contact with the outer periphery of the sphere 2 also rotates. In this case, the sphere 2 rolls in the same direction as the moving direction of the housing 1, and rotates by an amount corresponding to the moving amount of the housing 1. Furthermore, the rotation shaft 8a is detected by the position information detection units 9a+9b provided on the rotation shafts 6a and 6b.

6b is detected, a circuit provided on the printed circuit board 11 generates a signal corresponding to the detected value, and position information corresponding to the moving direction and amount of movement of the housing 1 can be detected. Ta.

The problem that the invention aims to solve Such conventional groove bottoms have the following problems.

As already explained, the input/output terminals 10 of the position information detecting section 91.9b provided at the tips of the rotating shafts 6a+6b are directly fixed to the printed circuit board 11 by soldering.

As a result, when soldering in the manufacturing process, the input/output terminals 1o protrude from the position information detection parts 9fL, 9b by about 8 terminals each, making it very difficult to insert them into the insertion holes of the printed circuit board 11. Have difficulty. Similarly, in the manufacturing process, when it becomes necessary to disassemble the product due to some kind of malfunction, or when the product is being used by an end user, dirt, dust, etc. on the mounting surface 4 may be transferred via the sphere 2 to the rotation axis 6λ.

6b etc. and malfunctions and requires disassembly and cleaning, it is necessary to separate the printed circuit board 17 and the input/output terminals 10 by melting the solder, and the soldered parts of the multiple input/output terminals 1o It is very difficult to separate the parts, and it also causes damage to the soldered parts of the printed circuit board 11 and damage to the input/output terminals 10, which impairs work efficiency and parts yield, and increases costs. This made maintenance difficult.

The present invention solves these conventional problems and provides an inexpensive position information input device with stable quality by making the connection between the input/output terminal of the position information detection section and the printed circuit board removable. This is what I am trying to do.

Means for Solving the Problems In order to solve this problem, the present invention provides a housing that can move on a plane, and a housing that rotates as the housing moves on the plane. A housing is provided with a sphere rotatably provided on the housing, a position information detection unit that detects the direction and amount of movement of the housing by rotation of the sphere, and a position information conversion means that converts a signal in accordance with the first detection. Further, the position information detection section and the position information conversion means are configured to be detachably connected to each other by one flexible wiring board.

Effects The present invention, as configured above, can facilitate product assembly and disassembly by connecting the position information detecting section and the position information converting means in a detachable manner using one flexible pattern. .

Further, the output voltage obtained at the terminal 23 of the light receiver 31 changes depending on the amount of light it receives.

Therefore, the rotary plate 28 between the light receiver 31 and the light emitter 3o
When the slit position changes, the amount of light passing through it changes, and the output voltage of the photoreceiver 31 changes accordingly. As a result of the above, the rotary plate 28 is connected to the rotary shaft 20&,
When rotating together with 20b, the output voltage appearing at terminal 23 changes as shown in the sixth color.

The rotating shafts 2C)a and 20b which are in contact with the outer periphery of 9 also rotate. In this case, the sphere 19 rolls in the same direction as the moving direction of the housing 16, and rotates by an amount corresponding to the moving amount of the housing 15. Further, the rotating shaft 20a
