  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The swimming body device 1 according to the embodiment of the present invention can be suitably applied to a game device or the like. As shown in FIG. 1, this swimming body device 1 includes a swimming body 2 and a swimming body control device 3. The swimming body 2 can also be used for the swimming body control devices 4 and 5 described later.

  As shown in FIG. 2, the swimming body 2 includes a swimming body portion 21 and a fin portion 22 located at the rear end portion thereof. The fin portion 22 is connected to the rear end portion of the swimming main body portion 21.

  Although the shape of the swimming body 21 is not particularly limited, a fish shape, a sea animal shape, a mermaid shape, or the like in which the swimming body 2 is recognized as a natural integrated form by connecting the fin portion 22. It is preferable to do so. In addition, the swimming body 21 can be in the shape of a pet such as a person having character and animals and plants. The swimming body 21 can be selected by a person who plays the game, for example, or can be customized. The swimming body 21 can be easily manufactured by using a 3D printer or the like. The swimming body 21 can have a length in the front-rear direction of, for example, about 2 cm to 4 cm.

  The fin portion 22 is equipped with a magnet 23 having a magnetization direction in the front-rear direction of the swimming body 2. The magnet 23 has a rod shape that is long in the magnetization direction. In the present embodiment, the magnet 23 has an S pole on the rear end side and an N pole on the front end side. In FIGS. 2A and 2B, the magnet 23 is schematically drawn through. In the description of the present application, the front-rear direction of the swimming main body 21, the fin portion 22, and the magnet 23 is the same as the front-rear direction of the swimming book 2.

  The fin portion 22 is formed of a flexible member (base material) such as silicon resin, and the magnet 23 is mounted inside the magnet mounting portion 22a. The fin portion 22 can be manufactured by, for example, placing a magnet 23 in a molding die and injecting silicon resin or the like around the magnet 23 to harden it. The fin portion 22 has a wide side surface 22b like a tail fin such as a fish (or sea beast). The fin portion 22 can have a length in the front-rear direction of, for example, about 1 cm to 2.5 cm, and a thickness (a length in a direction orthogonal to the wide side surface 22b) of about 0.1 cm to 0.5 cm.

  The fin portion 22 preferably has a sack portion 22c. The sack portion 22 c is inserted in the vicinity of the rear end portion of the swimming main body 21 and is closely attached to the periphery thereof by elastic deformation, thereby being connected to the swimming main body 21. Therefore, the sac portion 22c has a bottomed hollow portion and can be easily elastically deformed (for example, made of silicon resin). The sack portion 22c may be formed integrally with the other portion of the fin portion 22, but may be bonded to the other portion of the fin portion 22 with an adhesive. Such a sac portion 22c can easily connect the fin portion 22 to the swimming main body portion 21. In addition, the fin part 22 does not have the sack part 22c depending on the case, and it is also possible to fix and connect to the swimming main body part 21 with an adhesive or the like.

  The magnet 23 mounted on the fin portion 22 is displaced when an AC magnetic field described later is received in a water tank 31 (or 41 or 51) described later. More specifically, since the force acting on the rear end and the front end is in the opposite direction, the magnet 23 is displaced so as to rotate when it receives an AC magnetic field. Then, as shown in FIG. 3, the fin portion 22 is elastically deformed and vibrated in accordance with the displacement of the magnet 23, and generates the propulsive force of the swimming body 2 by pushing the surrounding water backward.

  In addition, the fin part 22 can be connected to the swimming main body part 21 so that the wide side surface 22b is in the vertical direction in the aquarium (see FIGS. 2A and 2B). Further, as shown in FIG. 13 described later, when the swimming body 2 is used in the water tank 51 of the swimming body control device 5, the swimming body control device 5 can generate a three-dimensional magnetic field as described later. Therefore, as shown in FIGS. 4A and 4B, the fin portion 22 can be connected to the swimming body portion 21 so that the wide side surface 22b is in the horizontal direction.

  In addition, the buoyancy of the swimming body 21 is adjusted. When the swimming body 2 is used in the water tank 31 of the swimming body control device 3 or in the water tank 41 of the swimming body control device 4 as shown in FIG. 8 described later, the swimming body control device 3 is one-dimensional as will be described later. Since the magnetic field is generated and the swimming body control device 4 generates a two-dimensional magnetic field, the swimming body 2 is set to sink to the bottom of the water tank 31 (or 41) (see FIGS. 1 and 8) or floats on the water surface. To adjust the buoyancy. When the swimming body 2 is used in the water tank 51 of the swimming body control apparatus 5 as shown in FIG. 13, the swimming body control apparatus 5 can generate a three-dimensional magnetic field, as will be described later. Adjusts the buoyancy so that it can swim regardless of the depth of the aquarium 31 underwater.

  Next, the swimming body control device 3 will be described. The swimming body control device 3 includes a water tank 31, a magnetic field generation unit 32, a magnetic field control unit 33, and an operation unit 34 (see FIG. 1).

  The aquarium 31 can store water for the swimming body 2 to swim therein. Moreover, the water tank 31 is provided with a structure 31a having a passage 31aa. The structure 31a having the passage 31aa can be various, and may be one in which a hole of the passage 31aa is formed, or simply defines the passage 31aa by being depressed or standing upright. May be. As shown in FIGS. 5A, 5B, and 5C, the structure 31a of the present embodiment is provided on the bottom plate with two rectangular thin plates perpendicular to the x-axis direction and two perpendicular to the y-axis direction. Thus, a total of nine small spaces are formed, and a dome-shaped passage 31aa is provided in a partition wall in each direction below the small spaces. The x-axis direction and the y-axis direction are both horizontal directions and directions orthogonal to each other. It is also possible to make a maze without providing some of the plurality of passages 31aa. It is also possible to specify the starting point and goal point. The user can enjoy the swimming body 2 through various passages 31aa by operating the operation unit 34 described later. In addition, the structure 31a can be a combination of a rectangular thin plate and a cylinder provided with a passage 31aa or an electric gate. The shape of the passage 31aa can be various.

  The magnetic field generator 32 has a pair of coils facing each other across the water tank 31 (see FIGS. 5A to 5C). In other words, the magnetic field generator 32 has a pair of x-axis coils 32x and 32x ′ that generate a magnetic field in the x-axis direction, which is a pair of coils.

  The magnetic field control unit 33 controls the magnetic field generation unit 32. Based on the control signal from the operation unit 34, the magnetic field control unit 33 causes the pair of x-axis coils 32x and 32x ′ of the magnetic field generation unit 32 to generate an AC magnetic field by passing an AC current in the x-axis magnetic field control unit 33x. . Therefore, the AC magnetic field can be generated in a one-dimensional direction. The AC magnetic field changes with time at a predetermined frequency and amplitude, and may have a bias (DC component). The alternating magnetic field shown in FIG. 6 (a) is a case where there is no bias, and the alternating magnetic field shown in FIG. 6 (b) is a case where there is a positive bias. The alternating magnetic field is used to propel the swimming body 2 and also to control the traveling direction.

  In addition, in FIG. 1, FIG. 5A-FIG. 5C (and FIG. 8, FIG. 9A-FIG. 9C mentioned later, FIG. 13, FIG. 14A-FIG. 14C), each member (water tank, structure, coil, etc.) required by see-through | perspective Is shown. Further, in FIG. 1 (and FIG. 5B), one coil 32x of the pair of x-axis coils 32x and 32x ′ overlaps the other coil 32x ′ and is hidden. Further, in FIG. 1, reference numerals 33xa and 33xb are electric wirings connected to both ends of one coil 32x of the pair of x-axis coils 32x and 32x ', and reference numerals 33xa' and 33xb 'are a pair of x-axis coils. Electric wiring connected to both ends of the other coil 32x ′ of 32x and 32x ′ is shown.

  The magnet 23 of the swimming body 2 is displaced according to the AC magnetic field unless the front-rear direction (N-pole-S-pole direction) completely coincides with the direction of the AC magnetic field, whereby the fin portion 22 vibrates, The swimming body 2 advances by the driving force. When there is no AC magnetic field bias, the magnet 23 of the swimming body 2 is displaced symmetrically with respect to the longitudinal axis thereof, so that the fin portion 22 vibrates symmetrically and the swimming body 2 goes straight (see FIG. 3). ). When the AC magnetic field has a bias, the magnet 23 of the swimming body 2 is displaced asymmetrically with respect to the front-rear direction, and the fin portion 22 vibrates asymmetrically so that the swimming body 2 changes its traveling direction. For example, when the rear end side of the magnet 23 is the S pole and the front end side is the N pole as in the present embodiment, and the magnetic field from the coil 32x ′ toward the coil 32x is in the positive direction, the AC magnetic field having a positive bias is in the positive direction. Is larger than the magnetic field in the negative direction, the swimming body 2 changes its traveling direction by gradually changing its direction clockwise. On the other hand, since the alternating magnetic field having a negative bias has a larger negative magnetic field than the positive magnetic field, the swimming body 2 changes its traveling direction by gradually turning counterclockwise.

  Thus, an alternating magnetic field can be generated in a one-dimensional direction by the pair of coils 32x and 32x ', and the swimming body 2 can be advanced in a two-dimensional arbitrary direction or the traveling direction can be changed.

  The operation unit 34 controls the magnetic field control unit 33 to change the operation state of the swimming body 2. Specifically, as shown in FIGS. 7A and 7B, the operation unit 34 includes a horizontal operation device 34a and a frequency setting device 34b. These are attached to the operation unit main body 34c. The operation unit 34 controls the magnetic field control unit 33 by communicating with the magnetic field control unit 33 via the electric wiring cable 34A or wirelessly. In the case of wireless, a wireless communication device is provided for each of the operation unit 34 and the magnetic field control unit 33.

  The horizontal operation device 34a determines the amplitude and bias of the alternating magnetic field by its operation, thereby determining the speed and traveling direction of the swimming body 2. The horizontal operation device 34a includes an operation gripping portion 34aa that is gripped by an operator. The operation gripping portion 34aa is usually a rod-shaped member protruding from the operation portion main body 34c. The horizontal operation device 34a corresponds to “front side”, “rear side”, “left side”, “right side” in the water tank 31 and the letters “F”, “B”, “L”, “R”. Or the character or mark equivalent to them can be attached. The horizontal operation device 34a can have the structure described below.

  As in a general joystick, the horizontal operation device 34a can have a structure in which the operation gripping portion 34aa can be tilted in any direction with the root as a fixed point (FIGS. 7A and 7B). reference). Then, the amplitude of the alternating magnetic field is changed corresponding to the absolute value of the component in the front-rear direction in the direction in which the operation gripping portion 34aa is tilted (the direction in plan view), and the bias of the alternating magnetic field is corresponding to the component in the left-right direction. Can be changed.

  The frequency setting device 34b sets the frequency (for example, 5 to 20 Hz) of the alternating magnetic field generated by the magnetic field generator 32. The frequency setting device 34b can be in the form of a cylindrical knob. The frequency of the alternating magnetic field is changed by turning the frequency setting device 34b. This change in frequency is because the optimum frequency for obtaining a propulsive force may vary depending on the size or weight of the swimming body portion 21 and the fin portion 22 in the swimming body 2. In addition to the knob, the frequency setting device 34b may have other forms such as a slider.

  Next, the swimming body control device 4 that can be used in place of the swimming body control device 3 will be described. As shown in FIG. 8, the swimming body control device 4 includes a water tank 41, a magnetic field generation unit 42, a magnetic field control unit 43, and an operation unit 44. In these, water tank 41 (and structure 41a, channel 41aa) is the same as water tank 31 (and structure 31a, channel 31aa) mentioned above.

  As shown in FIGS. 9A, 9B, and 9C, the magnetic field generator 42 has two pairs of coils facing each other with the water tank 41 interposed therebetween. That is, the magnetic field generation unit 42 is a pair of x-axis coils 42x and 42x ′ that generate a magnetic field in the x-axis direction, which is a pair of coils, and a pair of y-axis coils 42y and 42y that generate a magnetic field in the y-axis direction. 'have.

  The magnetic field controller 43 controls the magnetic field generator 42. Based on the control signal from the operation unit 44, the magnetic field control unit 43 generates a current (a combined current of a direct current and an alternating current) in the pair of x axis coils 42x and 42x ′ of the magnetic field generation unit 42 in the x axis magnetic field control unit 43x. To generate an x-axis component of a static magnetic field (a magnetic field that does not change with time) and an x-axis component of an alternating magnetic field, and a pair of y-axis coils of the magnetic field generation unit 42 in the y-axis magnetic field control unit 43y A current is passed through 42y and 42y ′ to generate the y-axis component of the static magnetic field and the y-axis component of the alternating magnetic field. The direction of the alternating magnetic field is orthogonal to the direction of the static magnetic field. Unlike the case of the swimming body control device 3 described above, the AC magnetic field does not have a bias. The static magnetic field and the alternating magnetic field can be in any two-dimensional direction, that is, can be directed in any two-dimensional direction (see FIGS. 10A and 10B).

  In FIG. 8 (and FIG. 9B), one coil 42x of the pair of x-axis coils 42x and 42x 'is hidden by overlapping with the other coil 42x'. In FIG. 8, reference numerals 43xa and 43xb denote electrical wirings connected to both ends of one of the pair of x-axis coils 42x and 42x ', and reference numerals 43xa' and 43xb 'denote a pair of x-axis coils. Electrical wires connected to both ends of the other coil 42x ′ of 42x and 42x ′, reference numerals 43ya and 43yb are connected to both ends of one coil 42y of the pair of y-axis coils 42y and 42y ′. The electrical wirings and reference numerals 43ya ′ and 43yb ′ respectively indicate electrical wirings connected to both ends of the other coil 42y ′ of the pair of y-axis coils 42y and 42y ′.

  The static magnetic field is used to control the traveling direction of the swimming body 2, and the direction is the target traveling direction of the swimming body 2. The alternating magnetic field is used to propel the swimming body 2. When the traveling direction of the swimming body 2 does not coincide with the target traveling direction, the magnet 23 of the swimming body 2 rotates so as to be parallel to the direction of the static magnetic field, and the swimming body 2 rotates according to the rotation. Then, the traveling direction is changed so as to coincide with the traveling direction of the target. Further, the magnet 23 of the swimming body 2 is displaced unless the front-rear direction (N-pole-S-pole direction) completely coincides with the direction of the alternating magnetic field, and the fin portion 22 vibrates according to the displacement, The swimming body 2 advances by the driving force.

  Thus, by having two pairs of coils, it is possible to generate a static magnetic field and an alternating magnetic field perpendicular to the two-dimensional arbitrary direction, and to advance the swimming body 2 in the two-dimensional arbitrary direction or to change the traveling direction. Can be changed.

  The operation unit 44 controls the magnetic field control unit 43 to change the operation state of the swimming body 2. Specifically, the operation unit 44 includes a horizontal operation device 44a and a frequency setting device 44b as shown in FIGS. These are attached to the operation unit main body 44c. The operation unit 44 controls the magnetic field control unit 43 by communicating with the magnetic field control unit 43 via the electric wiring cable 44A or wirelessly. In the case of wireless, a wireless communication device is provided for each of the operation unit 44 and the magnetic field control unit 43.

  The horizontal operation device 44a determines the horizontal direction of the static magnetic field by its operation, thereby determining the horizontal direction of travel of the swimming body 2, and also determines the amplitude of the alternating magnetic field, thereby swimming. The speed of the body 2 is determined. The horizontal operation device 44a has an operation gripping portion 44aa that is gripped by an operator. The operation gripping portion 44aa is normally a rod-like member protruding from the operation portion main body 44c. The horizontal operation device 44a corresponds to “front side”, “rear side”, “left side”, “right side” in the water tank 41, and the letters “F”, “B”, “L”, “R”. Or the character or mark equivalent to them can be attached. The horizontal operation device 44a can have the structure described below.

  The horizontal operation device 44a can have a structure in which the operation gripping portion 44aa can be tilted in any direction with the base of the operation gripping portion 44aa as a fixed point like a general joystick (FIGS. 11A and 11B). reference). The direction in which the operation gripping portion 44aa is tilted (the direction in plan view) becomes the direction of the horizontal static magnetic field by the magnetic field generation unit 42, and thus can be the horizontal direction of travel of the swimming body 2. . Further, the amplitude of the alternating magnetic field is changed by the magnetic field generator 42 in accordance with the angle at which the operation gripping portion 44aa is tilted (the angle formed between the operation gripping portion 44aa and the operation portion main body 44c). Can be changed.

  In addition, as shown in FIG. 12, the horizontal operation device 44a can move the operation gripping portion 44aa in the radial direction from the center 44ab of the horizontal operation device 44a and can rotate around the center 44ab. Structure. Then, the direction of the operation gripping portion 44aa with respect to the center 44ab becomes the direction of the static magnetic field by the magnetic field generator 42, and therefore, it can be the horizontal traveling direction of the swimming body 2. Further, the amplitude of the alternating magnetic field is changed by the magnetic field generator 42 in accordance with the distance of the operation gripping portion 44aa from the center 44ab, so that the speed of the swimming body 2 can be changed. In FIG. 12, reference numeral 44ac denotes a disc-shaped guide member provided with a guide groove 44ad for guiding the operation gripping portion 44aa in the radial direction, and can be rotated together with the operation gripping portion 44aa. Is.

  The frequency setting device 44b is the same as the frequency setting device 34b described above of the swimming body control device 3.

  Next, the swimming body control device 5 that can be used in place of the swimming body control device 3 or the swimming body control device 4 will be described. As shown in FIG. 13, the swimming body control device 5 includes a water tank 51, a magnetic field generation unit 52, a magnetic field control unit 53, and an operation unit 54.

  The water tank 51 is the same as the water tank 31 described above. The structure 51a may be the same as the structure 31a described above, but in this embodiment, as shown in FIGS. 14A, 14B, and 14C, a rectangular thin plate is perpendicular to the x-axis direction. 2 sheets orthogonal to the y-axis direction and 2 sheets orthogonal to the z-axis direction (depth direction (vertical direction)) intersecting each other, forming a total of 27 small spaces The circular passage 51aa is provided in the partition wall in each direction of the small space. It is also possible to form a maze without providing some of the plurality of passages 51aa. It is also possible to specify the starting point and goal point. The user can enjoy the swimming body 2 through various passages 51aa by operating an operation unit 54 described later.

  The magnetic field generator 52 has three pairs of coils facing each other across the water tank 51 (see FIGS. 14A to 14C).

  The static magnetic field is used to control the traveling direction of the swimming body 2, and the direction is the target traveling direction of the swimming body 2. The alternating magnetic field is used to propel the swimming body 2. When the traveling direction of the swimming body 2 does not coincide with the target traveling direction, the magnet 23 of the swimming body 2 rotates so as to be parallel to the direction of the static magnetic field, and the swimming body 2 rotates according to the rotation. Then, it will match the direction of travel of the target. Further, the magnet 23 of the swimming body 2 is displaced unless the front-rear direction (N-pole-S-pole direction) completely coincides with the direction of the alternating magnetic field, and the fin portion 22 vibrates and swims according to the displacement. Body 2 progresses.

  Thus, by having three pairs of coils, it is possible to generate a static magnetic field and an alternating magnetic field perpendicular to the three-dimensional arbitrary direction, and to advance the swimming body 2 in the three-dimensional arbitrary direction or to change the traveling direction. Can be changed.

  The operation unit 54 controls the magnetic field control unit 53 to change the operation state of the swimming body 2. Specifically, as shown in FIGS. 16A and 16B, the operation unit 54 includes a horizontal direction operation device 54a, a frequency setting device 54b, and a vertical direction operation device 54d. These are attached to the operation unit main body 54c. The operation unit 54 controls the magnetic field control unit 53 by communicating with the magnetic field control unit 53 via the electric wiring cable 54A or wirelessly. In the case of wireless, a wireless communication device is provided for each of the operation unit 54 and the magnetic field control unit 53.

  The horizontal direction operation device 54 a is the same as the horizontal direction operation device 44 a described above of the swimming body control device 4. The frequency setting device 54b is the same as the frequency setting device 34b described above of the swimming body control device 3 (and the frequency setting device 44b described above of the swimming body control device 4).

  The vertical direction operation device 54d determines the inclination of the static magnetic field in the vertical direction (inclination from the horizontal direction to the vertical direction) by the operation, and thereby determines the inclination of the swimming body 2 in the traveling direction from the horizontal direction to the vertical direction. It is determined. The vertical direction operation device 54d can be in the form of a slider (see FIGS. 16A and 16B). The vertical operation device 54d in this form has a lever 54da that is held by an operator, and the inclination of the static magnetic field in the vertical direction can be changed by moving the lever 54da linearly. For example, when the lever 54da is located at the center, the swimming body 2 advances horizontally, when the lever 54da is above the center, the swimming body 2 is inclined upward, and when the lever 54da is below the center, the swimming body. 2 can be tilted downward and proceed.

  As described above, the swimming body 2 moves the fin portion 22 located at the rear end portion using a magnetic field, and thereby the passage 31aa (or 41aa or 51aa) in the water tank 31 (or 41 or 51). ) Can be swimmed by operation. The operation is generally performed while observing the entire swimming body 2 and the entire structure 31a (or 41a or 51a) in the aquarium 31 (or 41 or 51). It is also possible to incorporate a small video camera that can send an image by watching the image sent from the swimming body 2.

In addition to the game device, for example, it can be suitably applied to a learning device that learns the action of the magnetic field or learns the internal structure while the swimming body moves inside the structure, Further, when the operation gripping portions 34aa, 44aa, 54aa of the horizontal operation devices 34a, 44a, 54a are tilted (in the case of the shape shown in FIGS. 7, 11, 16) or moved (the shape shown in FIG. 12). In the case of rehabilitation, a load is applied or the operation unit measures the body movement using a video camera and outputs a control signal corresponding to the movement to the magnetic field control unit. The present invention can be suitably applied to the above-mentioned device or a device for preventing deterioration of physical ability due to age.
