Benefits of technology

The present invention is related to a drive controller for a radio-controlled toy ship. The invention includes water-detecting terminals at the bottom of the ship body, a water-detecting circuit, a motor driving switch, a super-reproducing receiving unit, a control circuit, a steering unit, a driving motor drive-amplifying unit, and a motor driving unit. The invention allows for the detection of water at the bottom of the ship body and the operation of the motor driving unit to move the ship. The technical effect of the invention is to provide a more efficient and reliable control system for radio-controlled toy ships.

Problems solved by technology

The rotation of the screw in air may cause any injury by making fingers into contact with the rotating screw, or any damage to both the rotating screw and an article by making the rotating screw into contact with the article.

Embodiment Construction

:

[0010] Other details, advantages and features of the present invention will be apparent from the following embodiments described with reference to the accompanying drawing.

[0011] As shown in FIG. 1, the drive controller comprises water-detecting terminals 2 for contacting with an external water, a water-detecting circuit 4 for detecting a short circuit current caused by contacting with water, a motor driving switch 6 having a closed state and an opened state which are controlled by the water-detecting circuit 4, a control IC 8 for generating a steering signal and a driving signal based on a received information, a driving motor drive-amplifying circuit 16 for amplifying a driving signal, a driving motor unit 18 including a motor which rotates with an amplified current for causing a screw to rotate, a steering drive-amplifier 20 for amplifying a steering signal, a steering unit 22 for changing a direction of a steering plate based on the amplified steering signal, an antenna 14 for ...

Abstract

A drive controller has means for detecting that a ship body lands on the water, and a function of allowing a drive upon detection of the landing and of inhibiting the drive upon non-detection of the landing.

Description

[0001] 1. Field of the Invention[0002] This invention relates to a driver for a toy, and to a drive controller for driving a screw operable only in the water.[0003] 2. Background Art[0004] A mobile body is frequently subject to a model controlled by a radio controller. A model of ship often utilizes a screw as driver similarly to the true ship. In fact, the screw has been used by taking into account a simple structure of a driver unit thereof as compared to a water-jet-type ship or a hovercraft-type ship.[0005] The end of the screw may often comprise three extremely sharp impeller blades which rotate in the water by the driver unit in order to generate a driving force, differently from automobiles. The sharp impeller blades of the screw for a toy ship have the following disadvantages. There is no problem as long as the screw rotates in the water. The rotation of the screw in air may cause any injury by making fingers into contact with the rotating screw, or any damage to both the ro...
