Background Art Fig. 1 is a schematic view illustrative of a radio controlled toy car.

In general, remote controller consists of controller body (1), front side or backside movement controlling part (2) and right hand side or left hand side movement controlling part (3).

Usually, front side or backside movement controlling part is made of stick (2) moving front or backside and right hand side or left hand side movement controlling part is made of stick (3) moving right or left side.

In the following description, the stick (2) moving front or backside is notified as front/back side controlling switch (2) and the stick (3) moving right or left side is described as right/left side controlling switch (3).

On the above constitution, the toy car will move front or back depending on the front/back side controlling switch (2) controlling.

On the above description, the meaning of front side movement of toy car indicates the car is moving in the direction of front side of toy car. Backside movement is vise versa.

When we would like to change the direction of the toy car, we can use right/left side controlling switch (3).

On the above description, in general the front wheel is rotating to move the car.

On the following description, left had turn means the front wheel turns in left hand side and right hand turn means the front wheel turns in right hand side.

Fig. 2 is a schematic view of electronic wiring for each switch.

There are the front/backside signal common electrode (5) attached on the front/back side controlling switch (2). Also there are front electrode (6a) and back electrode (6b).

In Fig 2, there are also direction turning common electrode (7) and left side electrode (8a) and right side electrode (8b).

Fig 3 is schematic view of controlling each switch.

According to Fig. 3a, when front/backside signal common electrode (5) is contacting front electrode (6a) and direction turning common electrode (7) is contacting left side electrode (8a), then the toy car (15) will move in front side (11) and turn to left as the front wheel (16) will turn to left (17a) as indicated.

According to Fig. 3b, when front/backside signal common electrode (5) is contacting front electrode (6a) and direction turning common electrode (7) is contacting right side electrode (8b), then the toy car (15) will move in front side (ll) and turn to right as the front wheel (16) will turn to right (17b) as indicated.

According to Fig. 3c, when front/backside signal common electrode (5) is contacting front electrode (6a) and direction turning common electrode (7) is contacting right side electrode (8b), then the toy car (15) will move in front side (ll) and turn to right as the front wheel (16) will turn to left (17a) as indicated According to Fig. 3d, when front/backside signal common electrode (5) is contacting back electrode (6b) and direction turning common electrode (7) is contacting right side electrode (8b), then the toy car (15) will move in back side (13) and turn to right as the front wheel (16) will turn to right (17b) as indicated The former description in Fig. 3 is indicating that the car is in front side when we see it with the controller (1).

But if the direction of toy car is different, the car is moving and turning in unexpected way.

For example, when the car is moving in different direction, the turning direction of toy car is depicted in fig. 4.

According to Fig. 4a, when the toy car (15) is movingfarfrom thecontroller (l), if

the direction turning common electrode (7) is contacting left side electrode (8a), the front wheel (16) of toy car (15) is turning to left (17a). So the toy will turn to left (22) in the same direction (12) of right/left side controlling switch (3).

According to Fig. 4b, when the toy car (15) is moving close to the controller (l), if thedirection turning common electrode (7) is contacting left side electrode (8a), the front wheel (16) of toy car (15) is turning to left (17a). So the toy will turn to right (24) in the opposite direction (12) of right/left side controlling switch (3).

According to Fig. 4c, when the toy car (15) is moving right direction (25) to the controller (1), ifthedirection turning common electrode (7) is contacting left side electrode (8a), the front wheel (16) of toy car (15) is turning to left (17a). So the toy will turn to upside (24) in the different direction (12) of right/left side controlling switch (3).

According to Fig. 4d, when the toy car (15) is moving left direction (27) to the controller (l), ifthedirection turning common electrode (7) is contacting left side electrode (8a), the front wheel (16) of toy car (15) is turning to left (17a). So the toy will turn to downside (28) in the different direction (12) of right/left side controlling switch (3).

Fig. 4a, 4b, 4c, 4d indicate that the direction of the toy car is turning in different way as the controlling of switch of controller

In FIG. 8, it is described dependencies of controlling the switches of controller to the turning direction of toy car.

In FIG. 8a, there are figured the case that linear switch (32) is moved forward and the rotation switch is rotated counterclockwise (83).

In this case, front/backside common electrode (62) will contact with front side signal electrode (63a) to move the car forward direction and the rotational common electrode (71) will contact with counterclockwise rotational signal switch (72a).

So the counterclockwise rotational signal switch (72a) is contacting with left rotation signal electrode for front wheel of toy car (65a) through the counterclockwise signal common electrode (64)

In the result, the left rotation signal generation electronic part for front wheel of toy car (76a) will turn on to turn the front wheels (78) to left (17a).
