Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention provides an operating member made of a magnet or a magnetic material disposed on the upper surface of a container and provided with a magnet or a magnetic member provided in the container and linked to a driving unit. The present invention relates to an operation device using a magnet operated by the action of a body.

(Prior Art and Object of the Invention) Recently, a rotating core material inserted into a stem of an artificial flower having one end fixed to a base is linked to a motor that operates by sensing sound, and the rotating core material is removed. There is known an operating device that can rotate the stem to enjoy a change in appearance by rotating the stem.

The present invention proposes an operating device using a magnet that can be further developed using the idea that the sound sensor senses sound to rotate a motor by sensing sound, and an interesting operation can be obtained for an operating member using a magnet. That is its purpose.

(Means for Achieving the Object) As means for achieving the above object, the operating device using the magnet according to the present invention is characterized by having the following requirements.

(A) A drive unit and a magnet linked to the drive unit are provided in a container made of a non-magnetic material, and the magnet is located near the back side of the upper surface of the container.

(B) An operating member receiving the attraction force of the magnet is mounted on the upper surface of the container.

(C) The driving unit includes a motor, a mounting member rotatably provided on a rotating shaft driven by the motor, and a gear group meshed with a gear fixed to the rotating shaft and arranged on the mounting member. Wherein the magnet is provided on the mounting member and is fixed to a shaft of one of the gears of the gear group.

Note that a sensor switch for sensing an external stimulus may be provided in the drive circuit of the motor.

According to the above configuration, the rotation shaft is rotated by operating the motor, and further, the gear group of the attachment member meshing with the gear of the rotation shaft is rotated. Move around in a circular shape. Therefore, the magnet on the mounting member also rotates around the rotation axis. At the same time, the magnet rotates on the mounting member since it is fixed to the shaft of one of the gears of the gear group. The operating member on the upper surface of the container follows the movement of the magnet by the attraction force of the magnet, so that the operating member moves circularly on the upper surface of the container while rotating itself.

As described above, since the motion of the motion member revolves while rotating, the motion is complicated unlike the simple motion, so that a very interesting change in appearance can be enjoyed.

Further, by providing a sensor switch for sensing an external stimulus in the drive circuit of the motor, for example, a situation where there is communication between a person who has made a hand by using sound as the external stimulus and the device. Can be brought out.

(Example) Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

In the drawing, reference numeral 1 denotes an operating device using the magnet according to the present invention. The operating device 1 using this magnet is formed by a container 2 formed of a non-magnetic material and a magnet 6 linked to a driving unit 3 provided in the container 2.

The container 2 is formed by connecting a cylindrical upper member 2a and a lower member 2b having a bottom and an opening at the top, and the upper member 2a has a transparent peripheral wall and a sand magnet 4, 4,. And a small resin member 5 imitating the above. The small member 5 is provided with a magnet 5a. Further, the lower member 2b
A sensor switch switch 7 for sensing sound, a main switch 8, a power supply battery 9, the drive unit 3 and the magnet 6 are housed in the inside, and a part of the sensor switch 7 and the main switch 8 The power battery 9 is exposed from the side surface of the member 2b, and is replaceably provided at the center of the lower member 2b.

The sand magnets 4, 4,... May be iron sand having a magnetic material, and the magnet 5a may also be a magnetic material. Further, only the magnet 6 may be made of a magnetic material. In short, it is only necessary that one of them has a magnetic force.

The drive unit 3 includes a mounting member 21 rotatably provided on a rotating shaft 18 having a motor 10 that alternately rotates forward and backward as a driving source,
A gear group 25 and 24 arranged on the mounting member 21 while meshing with a gear 29 fixed on the upper part of the rotating shaft 18. The magnet 6 is provided on the mounting member 21 and One of the gear groups 25 and 24 is fixed to the shaft 23 of the gear 24. The gear 11 fixed to the output shaft of the motor 10 meshes with the reduction gears 13, 14, 16, 17 and the gear 17 meshes with the gear 19 fixed below the rotary shaft 18.

The sensor switch 7, the main switch 8, the power supply battery 9, and the motor 10 are electrically connected, and the motor 10 is formed so as to alternately rotate forward and backward.

According to the operating device 1 using the magnet having the above configuration, the fourth
As shown in FIGS. 7A and 7B, the sensing signal is transmitted through the transistor Q ₃ through J ₆ where the sound is sensed by the sound sensor switch 7.
Is supplied to, Q ₃ is turned on, the transistor Q is turned off by it, the transistor Q ₁ is turned on, the signal is supplied from J _3. When there is no sensed signal from the sound sensor switch 7, the transistors Q ₃ , Q ₂ , Q ₁ perform a reflection operation, and no signal is supplied from J ₃ . Therefore, as shown in FIG.
In which the pulse signal having a width corresponding to the length of the sensing sound from the J ₃ is output.

NAND gate UIa, UIb, resistor R ₈ , and capacitor C ₄
It is configured clock pulse oscillator C by, from the terminal 31, a clock pulse without f ≒ 1 Hz relation to signals from the J ₃ is output. NAND gate UIc, UID and resistor R ₁₇ signal controller 32 is configured by, the J ₃ and inputs a signal from the terminal 31, different levels of the two signals alternately as shown in FIG. 4 (b) The terminal 33,
Output from 34.

Two pairs of transistors Q ₄ , each connected in series,
The motor drive circuit 35 is constituted by Q ₅ , Q ₆ , Q ₇ and the resistors R ₁₀ , R ₁₁ , R ₁₂ , R ₁₃ . Then, as shown in FIG. 3, two signals having different levels from the terminals 33 and 34 alternately turn on and off Q ₄ and Q ₆ , thereby changing the direction of the signal voltage applied to the motor 10. , The motor alternately rotates forward and reverse. Therefore, by the operation of the motor 10, its rotational force is reduced by the gear 11 and the reduction gear 1.
It is transmitted to the rotating shaft 18 via 3, 14, 16, 17 and the gear 19,
This rotation shaft 18 rotates. When the rotating shaft 18 rotates, the gear groups 25 and 24 of the mounting member 21 meshing with the gear 29 of the rotating shaft 18 rotate, so that the mounting member 21 moves around the rotating shaft 18 in a circular shape. Therefore, the magnet 6 on the mounting member 21 also rotates around the rotation shaft 18. At the same time, since the magnet 6 is fixed to the shaft 23 of one gear 24 of the gear groups 25 and 24, it rotates on the mounting member 21. The operating members (small member 5 and sand magnet 4) on the upper surface of the container 2 follow the movement of the magnet 6 due to the attraction force of the magnet 6, so that the small member 5 and the sand magnet 4 rotate when they themselves. While moving on the upper surface of the container 2 in a circular shape. In addition, since the motor 10 rotates in the forward and reverse directions, the movements of the small member 5 and the sand magnet 4 also change in the forward and reverse directions. Therefore, interesting changes can be enjoyed.

Since the magnet 6 is formed so as to rotate itself independently of the mounting member 21, when the magnet 6 rotates, the magnet 6 and the sand magnets 4, 4,. Since the magnet 5a provided in the magnet 5 repels or attracts, irregular and unexpected movements can be expected at the time of repulsion.
