It is a flowchart which shows the process which the operation control part of the main toy body of FIG. 1 performs. It is a perspective view of the magnetic detection part of the main toy body of FIG. It is a front view of the magnetic detection part of the main toy body of FIG. It is a perspective view which shows typically the flow of the magnetic flux in the magnetic detection part of the main toy body of FIG.

  FIG. 1 shows the appearance of an example of a magnetic response toy for explaining an embodiment of the present invention.

  A magnetic response toy 1 shown in FIG. 1 includes a main toy body 2 and a secondary toy body 3. The main toy body 2 is configured in a shape imitating a sword that can be gripped by the user, and the secondary toy body 3 is configured as a belt that can be attached to the waist of the user.

  The sub-toy body 3 is provided with a magnetism generating member 31 such as a permanent magnet or an electromagnet, and the magnetic detection unit 21 including a magnetic field sensor is provided at the blade portion of the main toy body 2.

  The main toy body 2 is configured to be able to output an effect using, for example, voice or light, and the effect is output according to an operation on the trigger button 22 provided in the vicinity of the grip portion, for example. The main toy body 2 is provided with two operation modes (normal mode and special move mode) with different effects to be output, and the operation mode is switched according to the magnetic detection in the magnetic detection unit 21.

  FIG. 2 shows a functional configuration of the magnetic response toy 1.

  The main toy body 2 includes a magnetic detection unit 21, a trigger button 22 as an operation unit, a sound generation unit 23 and a light emitting unit 24 as operation units, and a sound generation unit for each operation mode (normal mode and special technique mode). 23, an operation storage unit 25 storing operation data of the light emitting unit 24, an operation control unit 26, and a power supply unit 27.

  The operation control unit 26 switches the operation mode when magnetism is detected by the magnetic detection unit 21. In this example, the operation control unit 26 first sets the operation mode to the normal mode as a power switch (not shown) provided in the power supply unit 27 is turned on to activate the main toy body 2. Then, when the magnetism detection unit 21 detects magnetism while the normal mode is set, the operation control unit 26 switches the operation mode to the special technique mode, and again after a predetermined time has elapsed from the transition to the special technique mode. Return the operation mode to the normal mode.

  Then, when the trigger button 22 is operated, the operation control unit 26 detects the operation, and based on the set operation mode and the operation data stored in the operation storage unit 25, the sound generation unit 23 and The light emitting unit 24 is operated.

  The sound generation unit 23 includes a sounding body such as a speaker, and generates sound corresponding to the operation mode under the control of the operation control unit 26. That is, when the magnetism is detected by the magnetism detecting unit 21 and the mode is switched to the special technique mode, a sound corresponding to the special technique mode (that is, an operation corresponding to the magnetism detected by the magnetism detecting unit 21) is generated. It is possible to make it. The light emitting unit 24 includes a light emitter such as an LED (Light Emitting Diode), and emits light in a mode corresponding to the operation mode under the control of the operation control unit 26. That is, when magnetism is detected by the magnetic detection unit 21 and switched to the special technique mode, it is possible to emit light in a manner corresponding to the special technique mode (that is, the magnetism is detected by the magnetic detection unit 21). It is possible to act accordingly.)

  The magnetic detection unit 21 will be described in detail later, but the main toy body 2 and the sub toy body 3 are in contact with or close to each other, and the magnetic generation member 31 is positioned within a range in which the magnetic detection unit 21 can detect magnetism. In addition, the magnetism generated by the magnetism generator 31 is detected.

  FIG. 3 shows a flow of processing executed by the operation control unit 26.

  The operation control unit 26 of the main toy body 2 first sets the operation mode to the normal mode as the main toy body 2 is activated (step S1).

  Then, the operation control unit 26 determines the presence or absence of magnetic detection in the magnetic detection unit 21 (step S2).

  When magnetism is detected by the magnetic detection unit 21 (step S2: Yes), the operation control unit 26 sets the operation mode from the normal mode to the deadly technique mode (step S3). Then, the operation control unit 26 resets the timer and starts measuring time (step S4).

  The operation control unit 26 determines whether or not the trigger button 22 has been operated (step S5). When there is a trigger operation (step S5: Yes), the operation control unit 26 performs the special move operation data corresponding to the special move mode stored in the operation storage unit 25 (that is, the magnetic detection unit 21 performs magnetism). (Operation data corresponding to the detection of sound) is read (step S6), and the sound generator 23 and the light emitting unit 24 are operated based on the read operation data (step S7). When there is no trigger operation (step S5: No), the processing of steps S6 and S7 is skipped.

Then, the operation control unit 26 refers to the timer, and determines whether or not the elapsed time t after shifting to the special move mode is equal to or shorter than a predetermined time t ₀ (for example, 30 seconds) (step S8). If the elapsed time t is the predetermined time _{t 0} less (step S8: Yes), the operation control unit 26 continues the Special Move mode, repeats the processing of steps S5 to S8. If the elapsed time t exceeds the predetermined time t ₀ (step S8: No), the operation control unit 26 ends the deathblow mode stops the time measurement, the process returns to the above step S1, the operation Set the mode to normal mode.

  When magnetism is not detected in the magnetic detection unit 21 (step S2: No), the operation control unit 26 determines whether or not the trigger button 22 is operated (step S9). When there is a trigger operation (step S9: Yes), the operation control unit 26 reads the normal operation data corresponding to the normal mode stored in the operation storage unit 25 (step S10), and adds the read operation data to the read operation data. Based on this, the sound generating unit 23 and the light emitting unit 24 are operated (step S11). If there is no trigger operation (step S9: No), the processing of steps S10 and S11 is skipped.

  The operation control unit 26 repeats the processes of steps S1 to S11 until the power supply unit 27 is turned off and the main toy body 2 is stopped.

  4 and 5 show the configuration of the magnetic detection unit 21. FIG.

  The magnetic detection unit 21 includes a magnetic field sensor 40 and a pair of magnetic field converging members 41 and 42, and is housed in the housing of the main toy body 2. The magnetic detection unit 21 of the main toy body 31 has a predetermined magnetic detection range, and when the magnetic generation unit 31 of the sub toy body 3 is within the magnetic detection range, the magnetism of the magnetic generation unit 31 is detected. It can be detected. Specifically, it is considered that the magnetism of the magnetism generating unit 31 can be detected by the magnetism detecting unit 21 when the magnetism detecting unit 21 of the main toy body 2 and the magnetism generating unit 31 of the sub toy body 3 are in contact with or close to each other. It is done. For example, the magnetic detection unit 21 is accommodated inside the side surface 43 of the blade portion of the side surface 43 of the housing of the main toy body 2, the side surface 43 is formed in a substantially flat surface, and the magnetic generation of the sub toy body 3 is generated. You may form the buckle part which accommodates the part 31 in a substantially plane. Further, for example, when the main toy body 2 or the sub toy body 3 has a three-dimensional shape, the buckle that houses the three-dimensional shape of the side surface 43 of the housing of the main toy body 2 and the magnetism generating unit 31 of the sub toy body 3. You may form in a three-dimensional shape which opposes the three-dimensional shape of a part. Further, for example, at least one of the main toy body 2 and the sub toy body 3 is provided with a mark or a design that serves as a standard for a magnetic detection possible range in which the magnetic detection unit 21 can detect the magnetism of the magnetic generation unit 31. It may be given. By setting it as the structure according to these examples, the magnetism generation part 31 of the sub toy body 3 can be easily placed in the magnetism detection possible range of the magnetism detection part 21. The shapes and designs of the main toy body 2 and the sub toy body 3 are not limited to those described above.

  The magnetic field sensor 40 is, for example, a magnetoresistive effect element (MR element), a reed switch, a Hall element, or the like. In the present embodiment, the magnetic field sensor 40 is arranged so that the operating magnetic field direction is substantially parallel to the side surface 43 of the housing. . The magnetic field converging members 41 and 42 are plate-like members made of a magnetic material. In the present embodiment, the magnetic field converging members 41 and 42 are disposed substantially parallel to the side surface 43 of the housing and sandwiching the magnetic field sensor 40 therebetween.

  The magnetic field converging member 41 has a first region A1 positioned on the first axis X passing through the magnetic field sensor 40 in the direction of the operating magnetic field of the magnetic field sensor 40, and substantially parallel to the side surface 43 of the housing and orthogonal to the direction of the operating magnetic field. Between the first region A1 and the second region A2 in a plane formed by the second axis A2 located on the second axis Y passing through the magnetic field sensor 40 in the direction and the first axis X and the second axis Y. It has the 3rd field A3 located. In the present embodiment, the third region A3 is configured to connect the first region A1 and the second region A2, but the present invention is not limited to this configuration. In short, in the third region A3, the magnetic flux φ flowing into the first region A1 can flow into the second region A2 via the third region A3, and the magnetic flux φ flowing from the second region A2 passes through the third region A3. It suffices if it is located between the first area A1 and the second area A2 so that it can flow into the first area A1.

  The magnetic field converging member 42 also has a first region B1 located on the first axis X that passes through the magnetic field sensor 40 in the direction of the operating magnetic field of the magnetic field sensor 40, and a first region that passes through the magnetic field sensor 40 in a direction orthogonal to the operating magnetic field direction. It has 2nd area | region B2 located on 2 axis | shaft Y, and 3rd area | region B3 located between 1st area | region B1 and 2nd area | region B2. In the present embodiment, the third region B3 is configured to connect the first region B1 and the second region B2, but the present invention is not limited to this configuration. In short, in the third region B3, the magnetic flux φ flowing into the first region B1 can flow into the second region B2 via the third region B3, and the magnetic flux φ flowing from the second region B2 passes through the third region B3. After that, it only needs to be positioned between the first region B1 and the second region B2 so as to be able to flow into the first region B1.

  The first regions A1 and B1 are provided point-symmetrically about the magnetic field sensor 40 with the magnetic field sensor 40 interposed therebetween on the first axis X. The second regions A2 and B2 are provided point-symmetrically about the magnetic field sensor 40 with the magnetic field sensor 40 interposed therebetween on the second axis Y. The third regions A3 and B3 sandwich the magnetic field sensor 40 on an axis that intersects the first axis X and the second axis Y at an angle of about 45 °, and are provided symmetrically about the magnetic field sensor 40. Yes. Note that the inclination angles of the outer edges a4, b4 of the third regions A3, B3 with respect to the first axis X and the second axis are not limited to 45 °.

  The end portions on the magnetic field sensor 40 side of the first regions A <b> 1 and B <b> 1 are formed in a tapered shape whose width gradually decreases toward the magnetic field sensor 40 so that the magnetic flux is converged on the magnetic field sensor 40. That is, the length l1 of the edge (inner edge) a1 and b1 on the magnetic field sensor 40 side of the first regions A1 and B1 is the edge (outer side) that intersects the first axis X on the side opposite to the magnetic field sensor 40 side. Edges) are formed shorter than the length l2 of a2 and b2.

  FIG. 6 schematically shows the flow of magnetic flux in the magnetic detection unit 21.

  6A shows a case where the magnetic pole pair of the magnetic generation member 31 is arranged along the first axis X, and the magnetic flux φ is from the magnetic generation member 31 to the first region A1 of the magnetic field convergence member 41. FIG. It flows into the magnetic field convergence member 41 from the outer edge a2 and converges toward the inner edge a1 of the first region A1 of the magnetic field convergence member 41. The magnetic flux φ is along the first axis X between the first region A1 of the magnetic field converging member 41 and the first region B1 of the magnetic field converging member 42 (that is, along the operating magnetic field direction of the magnetic field sensor 40). It flows into and passes through the magnetic field sensor 40, flows into the magnetic field focusing member 42 from the inner edge b1 of the first region B1 of the magnetic field focusing member 42, and is emitted from the outer edge b2 of the first region B1 of the magnetic field focusing member 42. Flows into the magnetism generating member 31. Therefore, when the magnetic pole pair of the magnetism generating member 31 is arranged along the first axis X, the magnetic flux φ is between the first region A1 of the magnetic field focusing member 41 and the first region B1 of the magnetic field focusing member 42. Since the magnetic field sensor 40 flows in and passes through the magnetic field sensor 40 along the direction of the operating magnetic field, the magnetic field sensor 40 can detect the magnetism of the magnetic generation member 31.

  FIG. 6B shows a case where the magnetic pole pair of the magnetism generating member 31 is arranged along the second axis Y, and the magnetic flux φ is different from the magnetic field sensor 40 side of the second region A2 of the magnetic field converging member 41. It flows into the magnetic field convergence member 41 from the edge (outer edge) a3 that intersects the second axis Y on the opposite side, passes through the second region A2 and the third region A3 of the magnetic field convergence member 41, and the inner end of the first region A1 It converges toward the edge a1. The magnetic flux φ is along the first axis X between the first region A1 of the magnetic field converging member 41 and the first region B1 of the magnetic field converging member 42 (that is, along the operating magnetic field direction of the magnetic field sensor 40). It flows into and passes through the magnetic field sensor 40, radiates from the outer edge b <b> 3 of the second region B <b> 2 through the first region B <b> 1 and the third region B <b> 3 of the magnetic field converging member 42 and flows into the magnetism generating member 31. Therefore, even when the magnetic pole pair of the magnetism generating member 31 is arranged along the second axis Y, the magnetic flux φ passes through the second region A2 and the third region A3 of the magnetic field converging member 41 and the magnetic field converging member 41 Between the first region A1 and the first region B1 of the magnetic field converging member 42, the magnetic field sensor 40 flows into and passes through the magnetic field sensor 40 along the direction of the operating magnetic field of the magnetic field sensor 40. Can be detected.

  FIG. 6C shows a case where the magnetic pole pair of the magnetism generating member 31 is arranged along an axis that intersects the first axis X and the second axis Y at an angle of about 45 °. The third region A3 of the converging member 41 flows into the magnetic field converging member 41 from the edge (outer edge) a4 opposite to the magnetic field sensor 40 side, passes through the third region A3 of the magnetic field converging member 41, and the first region A1. Is converged toward the inner edge a1. The magnetic flux φ is along the first axis X between the first region A1 of the magnetic field converging member 41 and the first region B1 of the magnetic field converging member 42 (that is, along the operating magnetic field direction of the magnetic field sensor 40). It flows into and passes through the magnetic field sensor 40, radiates from the outer edge b <b> 4 of the third region B <b> 3 through the first region B <b> 1 of the magnetic field converging member 42, and flows into the magnetism generating member 31. Therefore, even when the magnetic pole pair of the magnetism generating member 31 is arranged along an axis that intersects the first axis X and the second axis Y at an angle of approximately 45 °, the magnetic flux φ is the third of the magnetic field converging member 41. The magnetic field converging member 41 flows into the magnetic field sensor 40 along the operating magnetic field direction between the first region A1 of the magnetic field converging member 41 and the first region B1 of the magnetic field converging member 42 via the region A3. The sensor 40 can detect the magnetism of the magnetism generating member 31.

  As described above, the magnetic field sensor 40 in the direction of the operating magnetic field of the magnetic field sensor 40 is formed by the first area A1, B1, the second area A2, B2, and the third area A3, B3 of the magnetic field converging members 41, 42 surrounding the magnetic field sensor 40. The magnetic flux φ can be converged in the first regions A1 and B1 sandwiching 40 therebetween, and the magnetic flux φ can be passed in the direction of the operating magnetic field of the magnetic field sensor 40. As a result, even if the magnetic pole pair of the magnetic generation member 31 is deviated from the direction of the operating magnetic field of the magnetic field sensor 40, the magnetism of the magnetic generation member 31 can be detected by the magnetic detection unit 21.

  While the detectable range of the single magnetic field sensor 40 remains in a very narrow range directly above the magnetic field sensor 40, the magnetic field detection members 21 and 42 surrounding the magnetic field sensor 40 are provided to detect the magnetic detection unit 21. The possible range extends to the periphery of the magnetic field converging members 41 and 42 and is expanded as compared with the detectable range of the magnetic field sensor 40 alone.

  As described above, the accurate position and orientation of the magnetism generating member 31 with respect to the magnetic field sensor 40 are not required, and the handling of the magnetic response toy 1 can be facilitated.

  Preferably, the gap g2 between the magnetic field sensor 40 and each of the second regions A2 and B2 of the magnetic field converging members 41 and 42 is different from that of each of the first regions A1 and B1 of the magnetic field sensor 40 and the magnetic field converging members 41 and 42. It is made larger than the gap | interval g1 between. Thereby, when the magnetic pole pair of the magnetism generating member 31 is arranged along the second axis Y, the second axis Y where the magnetic flux φ is orthogonal to the direction of the operating magnetic field of the magnetic field sensor 40 between the second regions A2 and B2. , The magnetic flux φ can be more reliably converged in the first regions A1 and B1, and the magnetic flux φ can be passed in the direction of the operating magnetic field of the magnetic field sensor 40. 21 detection accuracy can be improved.

  Preferably, the gap between the second region A2 of the magnetic field focusing member 41 and the first region of the magnetic field focusing member 42 is larger than the gap between the first region of the magnetic field focusing member 41 and the magnetic field sensor 40, and the magnetic field The gap between the second region A2 of the converging member 42 and the first region of the magnetic field converging member 41 is made larger than the gap between the first region of the magnetic converging member 42 and the magnetic field sensor 40. As a result, when the magnetic pole pair of the magnetism generating member 31 is arranged along the second axis Y, the magnetic flux φ flows from the edge a3 of the second region A2 of the magnetic field converging member 41 and the magnetic field converging member 42 The magnetic flux φ flows from the edge b3 of the second region B2 of the magnetic field converging member 42 and is emitted toward the first region A1 of the magnetic field converging member 41. The magnetic flux φ flowing from the edges a3 and b3 is more reliably converged to the first regions A1 and B1, and the magnetic flux φ can be passed in the direction of the operating magnetic field of the magnetic field sensor 40, thereby detecting the magnetic field. The detection accuracy of the unit 21 can be increased.

  Preferably, the length l2 of the outer edges a2 and b2 of the first regions A1 and B1 of each of the magnetic field focusing members 41 and 42 and the length l3 of the outer edges a3 and b3 of the second regions A2 and B2 are set. Is substantially equal. Thereby, the detection sensitivity of the magnetic detection unit 21 when the magnetic pole pair of the magnetic generation member 31 is arranged along the first axis X, and the magnetic pole pair of the magnetic generation member 31 are arranged along the second axis Y. In this case, the detection sensitivity of the magnetic detection unit 21 can be made substantially equal.

  The inclination angle of the outer edges a4, b4 of the third regions A3, B3 with respect to the first axis X and the second axis is not limited to 45 °, but preferably the third regions of the magnetic field focusing members 41, 42, respectively. The outer end edges a4 and b4 of A3 and B3 are preferably inclined at an angle of about 45 ° with respect to the first axis X and the second axis Y. Accordingly, the detection sensitivity of the magnetic detection unit 21 when the magnetic pole pair of the magnetism generating member 31 is arranged to be inclined with respect to the first axis X and the second axis Y is expressed as the first axis X and the second axis Y. Can be balanced on both sides of an axis intersecting at an angle of approximately 45 °, that is, the symmetry axis of the first axis X and the second axis Y.

  Note that the outer end edges a2 and b2 of the first areas A1 and B1, the outer end edges a3 and b3 of the second area, and the outer edges a4 and b4 of the third area of each of the magnetic field focusing members 41 and 42 are linear. It is not limited to this, but may be curved.

  The magnetic material forming the magnetic field converging members 41 and 42 is preferably a soft magnetic material having high magnetic permeability and low residual magnetic flux density (low coercive force), and examples thereof include electromagnetic steel plates and permalloys. By using a soft magnetic material having a small residual magnetic flux density, the magnetic field converging members 41 and 42 themselves can be prevented from being permanently magnetized, and erroneous detection of magnetism in the magnetic detection unit 21 can be prevented.

  For example, the main toy body 2 and the secondary toy body 3 are stored in the same place (toy box or the like), and the secondary toy body 3 remains in contact with or close to the magnetic detection unit 21 of the main toy body 2. If the magnetic material that forms the magnetic field converging members 41 and 42 is a hard magnetic material having a large residual magnetic flux density, the magnetic field converging members 41 and 42 themselves are permanently magnetized, and are used as secondary materials. Even after the toy body 3 is separated from the main toy body 2, the magnetic field sensor 40 always detects the magnetic field generated by the magnetized magnetic field converging members 41 and 42, and a problem occurs in the magnetic detection in the magnetic detection unit 21.

  Therefore, by using a soft magnetic material as the magnetic material forming the magnetic field converging members 41 and 42, it is possible to prevent the magnetic field converging members 41 and 42 themselves from being permanently magnetized even in the above case. The magnetism generated by the magnetism generating member 31 of the toy body 3 can be appropriately detected by the magnetism detection unit 21.

  In this specification, the soft magnetic material has an initial permeability of 650 to 100,000 μi, a maximum permeability of about 10,000 to 500,000 μm, and a saturation magnetic flux density of 0.38 to 2.45 T, A magnetic material having a coercive force of about 0.32 to 80 A / m, and more specific material names include an electromagnetic steel plate (silicon steel plate), permalloy, and the like. In addition, it is desirable to use a grain-oriented electrical steel sheet that has relatively good properties necessary for achieving the object of the invention. For example, the initial permeability is about 14,000 μi, the maximum permeability is about 40,000 μm, the saturation magnetic flux It is desirable that the density is about 2.00 T and the coercive force is about 8 A / m.

  As mentioned above, although embodiment of this invention was described exemplifying the magnetic response toy 1 by which the main toy body 2 was comprised as a sword and the sub toy body 3 was comprised as a belt, this invention is not limited to what was mentioned above. The main toy body 2 and the secondary toy body 3 are not limited to swords and belts, but include, for example, swords, axes, spears, swords, guns, bows and arrows, hand arms, belts, medals, mobile phones, makeup tools, bangles, It can also be composed of figurines such as vehicle toys, doll bodies, animal dolls, cards, mascots, and the like.

  In addition, the main toy body 2 includes the magnetic detection unit 21, the trigger button 22 as the operation unit, the sound generation unit 23 and the light emission unit 24 as the operation unit, and the sound generation unit 23 and the light emission unit for each operation mode. The embodiment of the present invention has been described by taking the magnetic response toy 1 including the operation storage unit 25 storing the operation data of 24, the operation control unit 26, and the power supply unit 27 as an example. Not limited. For example, the main toy body 2 includes a magnetic detection unit 21 and an operation unit that performs an effect operation using sound or light in response to the magnetic detection unit 21 detecting magnetism. For example, it can also be set as the magnetic response toy provided with the magnetism generating members 31, such as a permanent magnet and an electromagnet. According to the magnetic response toy having this configuration, for example, when the main toy body 2 and the sub toy body 3 are in contact with each other or close to each other, the magnetism generating member 31 is positioned within a range in which the magnetism detection unit 21 can detect magnetism.
