  The present invention relates to an operation mechanism for performing operations on main bodies of various devices.

  For example, Patent Document 1 below discloses a configuration in which a magnet is provided in an operation unit as an example of an operation unit of a gas stove (see paragraph [0055] of Patent Document 1 and FIG. 7). Specifically, by providing magnets on the outer peripheral surface of the operation unit and the inner peripheral surface of the recess in which the operation unit is accommodated, the operation unit is automatically shifted to the initial posture by the magnetic force of the magnet. Be able to.

JP 2007-271231 A

  The conventionally known configuration as described above is merely for returning the rotational position of the operation unit, and is not for improving operability. In recent years, various devices with a simple configuration with few protrusions have been proposed for the purpose of improving design and ease of cleaning, among others, with simple designs based on flat surfaces. There is also known a device (for example, an IH cooking heater) configured and having an operation unit detachable from the flat surface. Such a detachable operation unit is excellent in design but may not be sufficient in operability, and an operation mechanism with high operability is desired.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an operation mechanism with high operability using an operation unit that can be attached to and detached from the main body.

  An operation mechanism according to the present invention includes a main body and an operation unit. The main body has a flat operation surface. The operation unit is detachable from the main body, has a flat facing surface that faces the operation surface in a state of being attached to the main body, and is operated so as to rotate or slide along the operation surface. Is done. The operation surface of the main body is provided with a main body-side magnet in which two or more north and south poles are alternately arranged. An operation side magnet in which two or more north and south poles are alternately arranged is provided on the facing surface of the operation section.

  According to such a configuration, the operation unit is attached to the main body so that the flat opposed surface of the operation unit faces the flat operation surface of the main body. Two or more N poles and S poles are alternately arranged on the main body side magnet provided on the operation surface of the main body and the operation side magnet provided on the opposing surface of the operation portion. Therefore, in a state where the operation unit is attached to the main body, each N pole of the operation side magnet faces each S pole of the main body side magnet, and each S pole of the operation side magnet faces each N pole of the main body side magnet. It becomes a state.

  When the operation unit is operated so as to rotate or slide along a flat operation surface, each N pole and each S pole of the operation side magnet facing each other and each N pole and each S pole of the main body side magnet The combination changes. With the change in the combination of each N pole and each S pole, a click feeling when operating the operation unit is obtained, so that the operability can be improved.

  The operation unit may be operated so as to rotate or slide in a predetermined operation direction along the operation surface. In this case, the two or more N poles and S poles in the main body side magnet and the operation side magnet may be alternately arranged along the operation direction.

  According to such a configuration, when the operation unit is operated so as to rotate or slide along a flat operation surface, a click feeling can be intermittently obtained along the operation direction. It can be improved further.

  The pitch in which the two or more N poles and S poles in the main body side magnet are alternately arranged along the operation direction, and the two or more N poles and S poles in the operation side magnet in the operation direction. The pitches arranged alternately along the pitch may be the same.

  According to such a configuration, when the operation unit is operated so as to rotate or slide along a flat operation surface, a click feeling can be obtained at a constant pitch along the operation direction. Can be further improved.

  The two or more N poles and S poles in the main body side magnet and the operation side magnet may have a width along the operation direction smaller than a width along a direction orthogonal to the operation direction. .

  According to such a configuration, since the width along the operation direction of each N pole and each S pole is small, a feeling of clicking can be obtained in smaller increments. Therefore, for example, when setting operation is performed using the operation unit, setting can be performed in smaller steps. Further, since the width along the direction orthogonal to the operation direction of each N pole and each S pole is large, a sufficient holding force by magnetic force can be obtained, and stable operation can be realized.

<First Embodiment>
FIG. 1 is a schematic perspective view showing a configuration example of an operation mechanism 1 according to the first embodiment of the present invention. The operation mechanism 1 is applied to a main body 10 of an apparatus such as an IH cooking heater, for example, and the user can set the apparatus by operating the operation unit 20.

  The main body 10 has, for example, a flat upper surface, and the upper surface constitutes the operation surface 11. The operation unit 20 can be attached to and detached from the operation surface 11 of the main body 10. The operation surface 11 of the main body 10 is a surface that receives an operation by a user. For example, the operation of the operation unit 20 is detected by a sensor (not shown) in the main body 10, and the operation of the device is based on the detection signal. Parameters (firepower, etc.) are set.

  In this example, the operation unit 20 is formed in a disc shape. The operation unit 20 is attached such that one end surface thereof faces the operation surface 11 of the main body 10. The operation unit 20 is rotatable about the axis L <b> 1 while being attached to the main body 10. Therefore, the user can perform a setting operation on the operation surface 11 of the main body 10 by rotating the operation unit 20 around the axis L1.

  FIG. 2 is a bottom view of the operation unit 20. The bottom surface of the operation unit 20 constitutes a facing surface 21 that faces the operation surface 11 in a state where the operation unit 20 is attached to the main body 10.

  The facing surface 21 is a flat surface like the operation surface 11, and the entire facing surface 21 contacts the operation surface 11 in a state where the operation unit 20 is attached to the main body 10. Therefore, when the operation unit 20 is operated and rotated about the axis L1, the operation unit 20 rotates in the circumferential direction along the operation surface 11 so that the opposing surface 21 is in sliding contact with the operation surface 11. It will be. That is, the operation unit 20 is operated so as to rotate in the operation direction D1 with the circumferential direction around the axis L1 as the operation direction D1.

  As shown in FIG. 2, an operation side magnet 22 including two or more N poles 221 and two or more S poles 222 is provided on the facing surface 21 of the operation unit 20. The operation-side magnet 22 is preferably embedded in the operation unit 20 so that there is no protrusion from the facing surface 21.

  In this example, two or more N poles 221 and S poles 222 are alternately arranged along the operation direction D1. That is, the S pole 222 is adjacent to both sides of the operation direction D1 with respect to the N pole 221, and the N pole 221 is adjacent to both sides of the operation direction D1 with respect to the S pole 222.

  FIG. 3 is a diagram for explaining a specific configuration of the operation-side magnet 22. In this example, each N pole 221 and each S pole 222 of the operation side magnet 22 are formed in a rectangular shape having the same shape.

  The width (short side) A1 along the operation direction D1 of each N pole 221 and each S pole 222 is smaller than the width (long side) A2 along the direction orthogonal to the operation direction D1. The N poles 221 and the S poles 222 are arranged side by side in the short side direction so that the long sides face each other, for example, the long side direction is the radial direction of the operation unit 20, and the short side direction is the operation side 20. It corresponds to the circumferential direction.

  A pitch P1 between the N pole 221 and the S pole 222 adjacent to each other along the circumferential direction of the operation unit 20 is larger than a width A1 along the operation direction D1 of each N pole 221 and each S pole 222. As the pitch P1 is smaller, more N poles 221 and S poles 222 are arranged along the operation direction D1.

  FIG. 4 is a partial plan view of the main body 10. A main body side magnet 12 including two or more N poles 121 and two or more S poles 122 is provided on the operation surface 11 which is the upper surface of the main body 10. The main body side magnet 12 is preferably embedded in the main body 10 so that there is no protrusion from the operation surface 11.

  The N poles 121 and the S poles 122 of the main body side magnet 12 are arranged side by side in the circumferential direction D2 centering on the axis L2. Specifically, two or more N poles 121 and S poles 122 are alternately arranged along the circumferential direction D2. The arrangement of the N poles 121 and the S poles 122 of the main body side magnet 12 around the axis L2 is as follows. The N poles 221 and the S poles 222 of the operation side magnet 22 around the axis L1 shown in FIG. This is consistent with the arrangement mode. The shape of each N pole 121 and each S pole 122 of the main body side magnet 12 is the same as the shape (width A1, A2, etc.) of each N pole 221 and each S pole 222 of the operation side magnet 22, for example.

  The operation unit 20 is mounted on the operation surface 11 so that the axis L1 is coaxial with the axis L2. Therefore, the circumferential direction D2 centered on the axis L2 coincides with the circumferential direction centered on the axis L1 of the operation unit 20, that is, the operation direction D1. The pitch at which the two or more N poles 121 and the S poles 122 in the main body side magnet 12 are alternately arranged along the operation direction D1 (circumferential direction D2) is such that the two or more N poles 221 and S in the operation side magnet 22 are arranged. It is the same as the pitch P1 (see FIG. 2) in which the poles 222 are alternately arranged along the operation direction D1.

  As described above, the arrangement of the N poles 121 and the S poles 122 of the main body side magnet 12 around the axis L2 and the N poles 221 and the S poles 222 of the operation side magnet 22 around the axis L1. Therefore, when the operation unit 20 is mounted on the operation surface 11, each N pole 121 and each S pole 122 of the main body side magnet 12 and each N pole of the operation side magnet 22 are arranged. 221 and each S pole 222 face each other. At this time, each N pole 121 of the main body side magnet 12 opposes each S pole 222 of the operation side magnet 22 and attracts each other by magnetic force, and each S pole 122 of the main body side magnet 12 corresponds to each N pole of the operation side magnet 22. Opposing to 221 and attracting each other by magnetic force. Thereby, the operation unit 20 is held on the operation surface 11 by the magnetic force acting between the main body side magnet 12 and the operation side magnet 22.

  When the operation unit 20 is rotated in the operation direction D1 about the axis L1, each N pole 121 of the main body side magnet 12 and each N pole 221 of the operation side magnet 22 face each other, and each of the main body side magnet 12 The S pole 122 and each S pole 222 of the operation side magnet 22 face each other. In this state, the main body side magnet 12 and the operation side magnet 22 repel each other. Therefore, after passing this state, each N pole 121 of the adjacent main body side magnet 12 and each S pole 222 of the operation side magnet 22 face each other, and each S pole 122 of the adjacent main body side magnet 12 and the operation side magnet 22. The respective N poles 221 are opposed to each other.

  Thus, when the operation unit 20 is operated so as to rotate along the flat operation surface 11, each N pole 221 of the operation side magnet 22 sequentially faces each adjacent S pole 122 of the main body side magnet 12. The S poles 222 of the operation side magnet 22 sequentially face the adjacent N poles 121 of the main body side magnet 12. That is, the combination of each N pole 221 and each S pole 222 of the operation side magnet 22 facing each other and each N pole 121 and each S pole 122 of the main body side magnet 12 changes. As the combination of the N poles 121 and 221 and the S poles 122 and 222 is changed, the main body side magnet 12 and the operation side magnet 22 repel each other due to the magnetic force, and a click feeling is obtained by attracting them again. The operability can be improved.

  In particular, in this embodiment, when the operation unit 20 is rotated, a click feeling can be obtained intermittently and at a constant pitch along the operation direction D1, so that the operability can be further improved. Furthermore, since the width A1 along the operation direction D1 of each N pole 121, 221 and each S pole 122, 222 is small, a click feeling can be obtained in smaller increments. Therefore, when setting operation is performed using the operation unit 20, it is possible to perform setting in smaller increments. Further, since the width A2 along the direction perpendicular to the operation direction D1 of each N pole 121, 221 and each S pole 122, 222 is large, a sufficient holding force by magnetic force can be obtained, and stable operation is realized. be able to.

  FIG. 5 is a diagram for explaining a modification of the specific configuration of the operation-side magnet 22. In this example, each N pole 221 and each S pole 222 of the operation side magnet 22 have the same shape, but are formed in a fan shape instead of a rectangular shape.

  The width B1 along the operation direction D1 of each N pole 221 and each S pole 222 is smaller than the width B2 along the direction orthogonal to the operation direction D1. A pitch P2 between the N pole 221 and the S pole 222 adjacent to each other along the circumferential direction of the operation unit 20 is larger than a width B1 along the operation direction D1 of each N pole 221 and each S pole 222. The smaller the pitch P2, the more N poles 221 and S poles 222 are arranged along the operation direction D1.

  Thus, each N pole 221 and each S pole 222 of the operation side magnet 22 are not limited to a rectangular shape, and can be formed in various other shapes. Each N pole 221 and each S pole 222 are not limited to the same shape, and may be formed in different shapes. In the example of FIGS. 3 and 5, a space is formed between the adjacent N pole 221 and S pole 222, but a configuration in which no space is formed may be employed. In this case, the pitches P1 and P2 between the adjacent N pole 221 and S pole 222 may coincide with the width A1 of the N pole 221 and the S pole 222 along the operation direction D1. The same applies to each N pole 121 and each S pole 122 of the main body side magnet 12.

Second Embodiment
FIG. 6 is a bottom view of the operation unit 30 used in the operation mechanism 1 according to the second embodiment of the present invention. The present embodiment is different from the above embodiment in that the operation unit 30 is not operated to rotate but is operated to slide along a predetermined operation direction D3. The operation direction D3 extends, for example, on a straight line.

  The bottom surface of the operation unit 30 constitutes a facing surface 31 that faces the operation surface 11 with the operation unit 30 attached to the main body 10. The facing surface 31 is a flat surface like the operation surface 11, and the entire facing surface 31 contacts the operation surface 11 in a state where the operation unit 30 is attached to the main body 10. Therefore, when the operation unit 30 is operated, the operation unit 30 slides in the operation direction D3 along the operation surface 11 so that the opposing surface 31 is in sliding contact with the operation surface 11.

  As shown in FIG. 6, an operation side magnet 32 including two or more N poles 321 and two or more S poles 322 is provided on the facing surface 31 of the operation unit 30. The operation side magnet 32 is preferably embedded in the operation unit 30 so that there is no protrusion from the facing surface 31.

  In this example, two or more N poles 321 and S poles 322 are alternately arranged along the operation direction D3. That is, the S pole 322 is adjacent to both sides of the operation direction D3 with respect to the N pole 321, and the N pole 321 is adjacent to both sides of the operation direction D3 with respect to the S pole 322. Each N pole 321 and each S pole 322 of the operation side magnet 32 are formed in a rectangular shape having the same shape.

  The width (short side) C1 along the operation direction D3 of each N pole 321 and each S pole 322 is smaller than the width (long side) C2 along the direction orthogonal to the operation direction D3. Each N pole 321 and each S pole 322 are arranged side by side in the short side direction so that the long sides face each other.

  A pitch P3 between the N pole 321 and the S pole 322 adjacent to each other along the operation direction D3 of the operation unit 30 is larger than the width C1 along the operation direction D3 of each N pole 321 and each S pole 322. However, in the example of FIG. 6, a space is formed between the adjacent N pole 321 and S pole 322, but a configuration in which no space is formed may be employed. In this case, the pitch P3 between the adjacent N pole 321 and S pole 322 may coincide with the width C1 of the N pole 321 and the S pole 322 along the operation direction D3.

  The operation surface 11 of the main body 10 is provided with a main body side magnet (not shown) in which each N pole and each S pole are arranged in the same arrangement manner as each N pole 321 and each S pole 322 of the operation side magnet 32. It is done. Therefore, in a state where the operation unit 30 is mounted on the operation surface 11, each N pole and each S pole of the main body side magnet and each N pole 321 and each S pole 322 of the operation side magnet 32 face each other, and the magnetic force As a result, the operation unit 30 is held on the operation surface 11.

  When the operation unit 30 is operated so as to slide along the flat operation surface 11, each N pole 321 of the operation side magnet 32 sequentially faces each adjacent S pole of the main body side magnet, and Each S pole 322 sequentially faces each N pole adjacent to the main body side magnet. In other words, the combination of each N pole 321 and each S pole 322 of the operation side magnet 32 facing each other and each N pole and each S pole of the main body side magnet changes. In connection with this, since the click feeling at the time of operating the operation part 30 is obtained, operativity can be improved.

  As described above, the operation unit 30 is not limited to the disc shape, and can be formed in various shapes such as a rectangular shape. In this example, the operation direction D3 of the operation unit 30 extends in a straight line, but the present invention is not limited to this.

  In the above embodiment, the case where the operation surface 11 of the main body 10 to which the operation units 20 and 30 are attached is the upper surface of the main body 10 has been described. However, the operation surface 11 is not limited to such a configuration, and may be configured by other surfaces such as a side surface of the main body 10. Further, the operation surface 11 may be configured by a part of any surface of the main body 10. That is, it is sufficient that at least a part of any surface of the main body 10 is the flat operation surface 11 and the operation unit 20 can be attached to and detached from the operation surface 11.

  The device to which the operation mechanism 1 according to the present invention is applied is not limited to the IH cooking heater, but may be other electric devices such as a television, a game, and a pointing device. In addition, the present invention can be applied not only to electric devices but also to various other devices such as a safe as long as the user needs to perform an operation.
