Abstract

PURPOSE:To make a unit which has no malfunction due to electromagnetic induction, is possible to be used at a dusty place, is simple in its structure and is miniaturized, by mounting a reflector on the lower part of a joy stick unit and providing a light emitting diode and 4 photodetectors on the other side of space. CONSTITUTION:A reflector 2 is provided on the lower part of a two-dimensional direction joy stick unit shaft 1, and a light emitting diode 3 and four photodetectors 4 are provided on the other side of space. The light emitted from the light emitting diode 3 is reflected by the reflector 2. When the two-dimensional direction joy stick unit shaft 1 is vertical to the four photodetectors 4, the reflected light is made incident upon the four photodetectors by the same light quantity. When the two-dimensional direction joy stick unit shaft 1 is not vertical to the four photodetectors, the light quantity which is made incident upon the four photodetectors changes according to the angle of the two-dimensional direction joy stick unit shaft 1. By this changed amount, the operation direction of the two-dimensional joy stick unit shaft 1 is determined.

Next, preferred embodiments of the present invention will be described. (B) When the two-dimensional directional control rod unit shaft 1 is tilted at a constant angle with respect to the four photodetectors 4, the change amount and direction are determined by the following method. (B) Incident light amount Pa to the four photo detectors,
Photocurrents Ia, Ib generated by Pb, Pc, Pd,
Ic and Id are voltage-converted to obtain voltage outputs Va, Vb, Vc and Vd proportional to the amount of incident light. (C) Perform the following calculation on this voltage output,
The operation direction of the two-dimensional operation rod unit shaft 1 is obtained from the obtained results Vx, Vy. Vy = (Va + Vb) − (Vc + Vd) Vy = (Vc + Vb) − (Va + Vd) The direction (θ) is obtained from the following formula from the coordinates where Vx is the X axis and Vy is the Y axis. (D) Even if the light emitting diode is directly attached to the lower part of the shaft of the two-dimensional operation rod unit, the same operation is performed. (E) Further, the reflector attached to the lower part of the shaft of the two-dimensional operation rod unit may be made of aluminum foil. (F) Further, when the axis of the two-dimensional directional control rod unit is tilted by a reflector plate, the amount of reflected light also changes, so the amount of light incident on the four photodetectors changes, which results in calculation results VX, Vy. Error occurs. In order to prevent this, the total incident light amount V0 of the four photodetectors is obtained by the following equation and the output light amount of the light emitting diode is controlled so that V0 becomes constant, so that the accuracy of the calculation results Vx and Vy can be increased. It was V0 = Va + Vb + Vc + Vd

As a result, the two-dimensional operation rod unit is inexpensive because it does not malfunction due to electromagnetic induction, can be used in a place with a lot of dust, and has a simple structure. Also, by making the photo detector small, the entire unit can be made as small as a little finger. This realizes a two-dimensional directional operation with a fingertip.
