  • control section 40 After each of the users selects the running body 1 or 2, the control section 40 generates the fanfare sound through the speaker 37 and subsequently generates the countdown sound.
  • each of the users operates the forward/backward input key 31 and the right/left input key 32 of the controller 3 or 4 to operate running of the running body 1 or 2.
  • each of the controllers 3 and 4 when a predetermined lapse time is reached by a lapse time measured by the clock circuit 41 after the start of the race, the selection of a running control signal by the control section 40 in a roulette manner starts. During the selection, the LEDs 36b of the display sections 36 sequentially and repeatedly emit light and stop emitting the light, and eventually, one running control signal is selected randomly. Then, the LED 36b of the display section 36 corresponding to the function of the selected running control signal emits light.
  • the user presses the signal transmission inputting section 35 to allow the light emitting section 33 to transmit to the running body 1 the selected running control signal which is one of the obstructing signals A and B, the power-up signal C, and the barrier signal E, with an instruction signal therefor as infrared signals.
  • the light emitting section 33 directly transmits the obstructing signal D to the running body 2.
  • the control section 16 makes the selected obstructing signal transmitted to the running body 2 from the forward light emitting section 13, the backward light emitting section 14, or both of the light emitting sections 13 and 14 depending on the signal.
  • An instruction signal is not always necessary. An instruction signal does not need to be transmitted to the running body 1 when the running body 1 is capable of determining the kind of a received obstructing signal, and transmitting the obstructing signal to the running body 2.
  • the control section 16 of the running body 2 limits the operation of the driving mechanism 12 thereof according to the received obstructing signal so that the running operation of the running body 2 is obstructed by means of backward movement, deceleration, spin, or the like.
  • the running body 1 which receives the power-up signal C accelerates itself to enhance the running ability thereof according to the received power-up signal C.
  • the running body 1 which receives the barrier signal E invalidates obstructing signals transmitted from the running body 2 and transmits the obstructing signals A and B toward the running body 2 in the forward and backward directions of the running body 1, respectively.
  • the running bodies 1 and 2 compete with each other in order to reach the goal first by transmitting obstructing signals each other and by enhancing their own running abilities by receiving power-up signals, for example.
  • the forward light emitting section 13 and the backward light emitting section 14 provided in the running body 1 transmit obstructing signals by radio in the forward and backward directions of the running body 1, respectively, the obstructing signals which obstruct running of the running body 2.
  • the light receiving section 15 provided in the running body 2 receives the obstructing signals, and the control section 16 controls an obstructing operation of the driving mechanism 12 of the running body 2 based on each of the received obstructing signals.
  • the running body 1 can obstruct running of the running body 2.
  • the running body 1 even when the running body 1 is about to obstruct running of the running body 2 which is running behind the running body 1, the running body 1 does not need to turn around to merely obstruct the running body 2.
  • the racing toy 100 can be enjoyed more for a long time by a user thereof without boredom compared with a conventional racing toy.
  • the light emitting section 33 of the controller 3 transmits a running operating signal according to the input performed through the forward/backward input key 31 or the right/left input key 32 to the running body 1.
  • the control section 16 of the running body 1 controls the running operation of the driving mechanism 12 of the running body 1 based on the running operating signal received at the light receiving section 15 thereof.
  • the control section 16 of the running body 1 controls the light emitting section 13 or 14 to transmit the obstructing signal based on the instruction signal received at the light receiving section 15.
  • a running operation of the running body 1 and transmission of an obstructing signal to the running body 2 can be performed by operations of only the controller 3.
  • the light emitting section 33 of the controller 3 can directly transmit an obstructing signal to the running body 2 too.
  • control section 40 of the controller 3 when the control section 40 of the controller 3 is triggered to start the selection of a running control signal by the clock circuit 41 which measures a lapse time from the start of running of the running body 1, the control section 40 randomly selects one of the running control signals stored in the signal storing section 34.
  • control section 40 of the running body 1 enhances the running ability of the running body 1 or reduces the running ability of the running body 2 according to the selected running control signal.
  • the running states of the running bodies 1 and 2 can be changed variously, and the play becomes diversified. Also, since the selection of a running control signal by the control section 40 is not determined by a user but in a roulette manner, which uses a random number, by the control section 40 randomly, the user can play while looking forward to how the running bodies 1 and 2 run next during the race. Also, by making each of the running bodies 1 and 2 run in a different way, the positions thereof can be reversed and re-reversed in the middle of the race.
  • the racing toy 100 can make up the shortage of fun and excitement which a conventional racing toy causes, and can be enjoyed more for a long time by a user thereof without boredom compared with a conventional racing toy.
  • the control section 40 of the controller 3 also controls the display section 36 to display a function of a selected obstructing signal.
  • the display section 36 displays the function of the selected obstructing signal in such a manner that a user can visually recognize how the running bodies 1 and 2 run next, the user can enjoy the race with alternate hope and fear by looking at the display
  • control section 40 of the controller 3 reproduces sound data corresponding to a selected obstructing signal and generates a sound through the speaker 37.
  • the obstructing signals are signals to move backward, spin, and decelerate the running body 2, respectively. Accordingly, the obstructing signals can put the running body 1 in a better position than the running body 2.
  • the power-up signal is a signal to accelerate the running body 1
  • the barrier signal is a signal to invalidate obstructing signals transmitted from the running body 2 so that the running of the running body 1 is not obstructed by the running body 2. Accordingly, the power-up signal and the barrier signal can put the running body 1 in a better position than the running body 2.
  • control section 40 selects a running control signal and controls the running body 1 or 2 according to the selected running control signal every time a lapse time measured by the clock circuit 41 reaches a predetermined lapse time, the running states of the running bodies 1 and 2 can be changed several times during the race.
  • obstructing signals may be transmitted not only in the forward and backward directions of the running body 1 but also in the right and left directions thereof.
  • obstructing signals are obstructing signals which are transmitted only in the forward direction or only in the backward direction of the running body 1, it is not necessary that the obstructing signals are transmitted only in one direction, and may be transmitted in both of the forward and backward directions thereof regardless of the kinds of the obstructing signals.
  • the obstructing signals in the above embodiments are merely examples, and the functions, the transmission directions, the signal reception ranges, and the like of the obstructing signals can be appropriately changed.
  • a metallic gate 50 may be provided on a course 70 on which the race is held, and a proximity sensor which detects the gate 50 when the running body 1 approaches the gate 50 may be provided with the running body 1, and the selection of a running control signal may be performed by the control section 16 in a roulette manner every time the running body 1 passes the gate 50.
  • the control section 16 of the running body 1 is provided with a roulette function and makes the selected running control signal transmitted to the running body 2.
  • the proximity sensor functions as a detecting section to detect the arrival of the running body 1 at a predetermined position.
  • the gate 50 and the proximity sensor function as the trigger providing section. That is, in this case, the selection control section and the trigger providing section are provided with the running body 1.
  • the selection control section and the trigger providing section are not necessarily provided with the controllers 3 and 4 or the running bodies 1 and 2 but may be provided with the gate 50 on the course 70, a side of the running path of the course 70, or a structure on the course 70 (a model of a building, for example).
  • the duty ratio in the PWM control of the motor 12b may be increased by keeping pressing the forward/backward input key 31 from a predetermined timing during the countdown to the start of the race so that the running body 1 is rapidly accelerated right after starting.
  • the running body 1 can be put in a better position than the running body 2 by using a kind of tricky technique.
