In the present specification, unless otherwise specified, the X1 side of each drawing is described as the right side, the X2 side as the left side, the Y1 side as the back side, the Y2 side as the near side, the Z1 side as the upper side, and the Z2 side as the lower side. To do.

  First, the configuration and operation of the information transmission apparatus 100 according to the first embodiment will be described with reference to FIGS.

  FIG. 1 is a perspective view showing an external appearance of the information transmitting apparatus 100. 2 is an internal schematic diagram illustrating the configuration of the information transmitting apparatus 100, FIG. 3 is an external schematic diagram illustrating the operation of the information transmitting apparatus 100, and FIGS. 4 and 5 are used in the information transmitting apparatus 100. FIG. 6 is an operation explanatory diagram of the rotary switch 10. FIG. 6 is an internal schematic diagram showing the operation of the information transmitting apparatus 100.

  An information transmitting apparatus 100 shown in FIG. 1 is used for controlling a distribution board for power management, and is configured to be able to transmit information selected by the information transmitting apparatus 100 to the outside. The information transmitting apparatus 100 includes a selection unit 1 that can detect one of a plurality of selection states by operating the operation unit 51. The selection unit 1 mainly includes a rotary switch 10, and the rotary switch 10 is disposed on the upper portion of the box 91.

  As illustrated in FIG. 2, the information transmission device 100 includes the selection unit 1, the selection determination unit 2, the power generation unit 3, the rectifier circuit 8, and the transmission unit 9 described above.

  The selection unit 1 includes a rotary switch 10 having a rotary shaft 62 and capable of detecting one selection state corresponding to the rotation angle of the rotary shaft 62. As shown in FIG. 2, the rotary switch 10 includes a pressing shaft 61, an operation knob 51 a as an operation unit 51, an insulating substrate 54, a fixed contact 52, a movable contact 53, and a terminal 55 in addition to the rotation shaft 62. And a pedestal 56. The fixed contact 52 is provided on the insulating substrate 54, and a terminal 55 is connected to the fixed contact 52. The terminal 55 extends into the box body 91 and is connected to the selection determination unit 2.

  A plurality of movable contacts 53 are attached to the rotary shaft 62, and an operation knob 51a is attached to the rotary shaft 62 as the operation unit 51. Therefore, the movable contact 53 is turned by rotating the operation knob 51a. The fixed contact 52 on the insulating substrate 54 is brought into contact or non-contact. As a result, one of a plurality of selected states can be detected.

  Further, the pressing shaft 61 passes through the inside of the rotating shaft 62 and is attached to the operation knob 51a. Further, the pressing shaft 61 is connected to the operation member 115 in the power generation unit 3 via the connecting member 117. . The pressing shaft 61 and the rotating shaft 62 are not connected and can be operated individually. The rotating shaft 62 and the pressing shaft 61 are attached to the operation knob 51a. However, when the operating knob 51a is rotated, the rotating shaft 62 is configured to rotate with the rotation of the operating knob 51a. Further, when the operation knob 51a is pressed downward, the pressing shaft 61 is pressed down, but the rotation shaft 62 is configured so as not to change its position. For example, if a plurality of vertical grooves are provided in the outer shape of the rotary shaft 62 and a plurality of convex portions are provided on the operation knob 51a so as to be engaged with the grooves, the above operation can be performed. When the operation knob 51a is rotated, the pressing shaft 61 may be rotated or may not be rotated. The switching operation of the rotary switch 10 as the selection unit 1 will be described later.

  The selection confirmation unit 2 has a function of confirming the selection information selected by the selection unit 1 described above. In the selection confirmation unit 2, the selection information transmitted from the rotary switch 10 via the terminal 55 is input and stored.

  The power generation unit 3 in the box 91 is configured to generate power when a pressing shaft 61 attached to the operation unit 51 is pressed. In other words, the power generation unit 3 generates power by pressing the operation knob 51a. The configuration and operation of the power generation unit 3 will be described later.

  A rectifier circuit 8 is connected to the power generation unit 3, and the electric power generated by the power generation unit 3 is converted into a DC voltage by the rectification circuit 8. The rectification circuit 8 is connected to the selection determination unit 2 and the transmission unit 9, and the power generated by the power generation unit 3 is supplied to the selection determination unit 2 and the transmission unit 9 via the rectification circuit 8.

  The transmission unit 9 is connected to the power generation unit 3 via the rectifier circuit 8 and is also connected to the selection determination unit 2. The transmission unit 9 is configured to transmit the information transmitted from the selection determination unit 2 including the selection state selected by the selection unit 1 to the outside using the power generated by the power generation unit 3. The transmitter 9 is connected to an antenna 9a and has a wireless communication function using a wireless local area network (LAN) or the like. Accordingly, it is possible to wirelessly transmit information including the selection state obtained by the selection unit 1 to the outside. Note that a wireless communication technique such as a wireless local area network (LAN) technique is a well-known technique, and thus the description of the internal configuration of the transmission unit 9 is omitted.

  As described above, since the selection unit 1 uses the rotary switch 10, the information transmission apparatus 100 can detect and output one of a plurality of selection states. At the same time, power is generated by pressing a pressing shaft 61 attached to the operation unit 51. The operation will be described with reference to FIGS.

  The rotary switch 10 can select one OFF state and four different ON states. Further, as shown in FIG. 4B or 5B, the rotating shaft 62 has movable contacts 53a, 53b, 53c, 53d corresponding to one OFF state and four different ON states, and 53e are arranged at a predetermined angle. In the case of the information transmitting apparatus 100, the angle is 45 °. Note that the length of the movable contact 53 a corresponding to the OFF state is set shorter than that of the other movable contacts 53.

  When the operation is not performed, the rotary switch 10 is OFF, and the operation knob 51a which is the operation unit 51 is lifted upward as shown in FIGS. 1 and 3A. . Further, as shown in FIGS. 1 and 3A, the indicated position of the operation knob is in the OFF position. At this time, the movable contact 53 is not in contact with the fixed contact 52 as shown in FIGS. 4 (a) and 4 (b). At this time, as shown in FIG. 2, the position of the lower end of the pressing shaft 61 is at the upper part in the box body 91, so the position of the operation member 115 in the power generation unit 3 is also at the upper part. Therefore, power generation is not performed.

  Next, when the ON1 state is selected by the rotary switch 10, as shown in FIG. 3B, the operation knob 51a is rotated by a predetermined angle while the operation knob 51a is lifted upward. . By this rotation, the information transmitting apparatus 100 has selected the ON1 state, and as shown in FIG. 3B, the rotary position of the rotary switch 10 becomes the ON1 position. At this time, as shown in FIGS. 5A and 5B, the movable contact 53 also rotates, and the movable contact 53 b that is used when the movable contact 53 is ON 1 contacts the fixed contact 52. As a result, the selection confirming unit 2 is notified that the ON1 state has been selected by the information transmitting apparatus 100. At this time, the position of the lower end of the pressing shaft 61 is at the upper part in the box 91, and therefore the position of the operation member 115 in the power generation unit 3 is also at the upper part. Therefore, power generation is not performed. Therefore, so far, the selection confirmation unit 2 and the transmission unit 9 have stopped operating.

  Next, while the ON1 state is selected by the rotary switch 10, as shown in FIG. 3C, the operation knob 51a is pressed downward. At this time, as shown in FIG. 6, the pressing shaft 61 is pressed downward while the movable contact 53 b is in contact with the fixed contact 52. Therefore, the operation member 115 in the power generation unit 3 is pushed down via the connecting member 117, and the operation member 115 moves to a position below the position shown in FIG. When such an operation is performed, the power generation unit 3 is configured to generate power. That is, the power generation unit 3 generates power by pressing the operation knob 51a.

  As described above, when power generation is performed in the power generation unit 3, power is supplied to the selection confirmation unit 2 and the transmission unit 9, so that the selection confirmation unit 2 and the transmission unit 9 can start operation. As a result, information related to the selection is transmitted from the transmission unit 9 to the outside by radio. In the above description, the case where the rotary switch 10 is changed from the OFF state to the ON1 state has been described, but the operation is the same in other combinations.

  Next, operation | movement of the electric power generation part 3 used with the information transmitter 100 is demonstrated using FIG.7 and FIG.8.

  7 is a side view of the power generation unit 3 in the first posture, and FIG. 8 is a side view of the power generation unit 3 in the second posture.

  As shown in FIGS. 7 and 8, a first opposing end face 114a and a second opposing end face 114b are formed on a magnetic path forming member 113 wound with a power generation coil (not shown). The rotating body 110 includes a permanent magnet 121, a first magnetizing member 122, and a second magnetizing member 123.

  In the state where the operation member 115 is not pressed, as shown in FIG. 7, the first end surface 122a of the first magnetizing member 122 faces the first opposing end surface 114a with a gap therebetween, and the second magnetizing member A first end surface 123a of 123 opposes the second opposing end surface 114b with a gap therebetween. In the state shown in FIG. 7, the first end surface 122a and the first opposing end surface 114a are magnetically attracted by the magnetic force of the permanent magnet 121, and the first end surface 123a and the second opposing end surface 114b are magnetically attracted. The rotating body 110 tries to be stabilized in the first posture.

  Next, when the operating member 115 is pressed, the rotating body 110 rotates and tries to be stabilized in the second posture shown in FIG. In the second posture, the second end face 122b of the first magnetizing member 122 faces the second facing end face 114b of the magnetic path forming member 113 via a minute gap, and the second end face 122b of the second magnetizing member 123 The second end face 123b faces the first opposing end face 114a with a small gap. Thereafter, when the pressing force to the operation member 115 is released, the operation member 115 and the rotating body 110 return to the first posture shown in FIG.

  In the first posture shown in FIG. 7, the magnetic flux φ1 generated from the permanent magnet 121 is changed from the first end surface 123a of the second magnetizing member 123 to the first of the magnetic path forming member 113 through the second opposing end surface 114b. The second arm 113b is given. The magnetic flux φ1 follows a path that reaches the first arm portion 113a via the connecting portion 113c of the magnetic path forming member 113, and passes from the first facing end surface 114a to the first magnetizing member 122 via the first end surface 122a. Return.

  In the second posture shown in FIG. 8, the magnetic flux φ2 emitted from the permanent magnet 121 follows a path from the first arm portion 113a to the second arm portion 113b via the connecting portion 113c. When changing from the magnetic flux φ1 to φ2 in the magnetic path forming member 113, an induced electromotive force can be obtained from the power generation coil. Similarly, when the magnetic flux is changed from φ2 to φ1 in the magnetic path forming member 113, an induced electromotive force can be obtained from the power generation coil. In the power generation unit 3, since the rotating body 110 and the magnetic path forming member 113 do not come into contact with each other, the force required to operate the operation member 115 is relatively weak. Can be obtained.

  As described above, the power generation unit 3 can easily generate power by the operation of the operation member 115, in other words, the pressing operation of the pressing shaft 61 in the vertical direction.

  As described above, the information transmission apparatus 100 includes the selection unit 1 that can detect one of a plurality of selection states, and generates power by pressing the operation unit 51 provided in the selection unit 1. Since the power obtained by the power generation is supplied to the transmission unit 9, it is possible to provide the information transmission device 100 corresponding to a plurality of selected states without requiring external energy supply.

  In the information transmitting apparatus 100, the rotary switch 10 capable of detecting a plurality of selection states corresponding to the rotation angle of the rotating shaft 62 is employed as the selection unit 1 capable of detecting one of the plurality of selection states. One of the plurality of selection states can be easily detected. Moreover, since the operation knob 51a provided with the pressing shaft 61 is attached to the rotating shaft 62, power generation can be easily performed by pressing the operation knob 51a.

  Further, in the information transmission apparatus 100, the transmission unit 9 is configured to transmit information including the selected state to the outside by radio, so that a line as a transmission path between the transmission unit 9 and the outside is not required. Therefore, the cost for the track can be reduced, and the installation layout of the information transmission apparatus 100 main body can be freely performed.

[Second Embodiment]
Next, the configuration and operation of the information transmission apparatus 200 according to the second embodiment of the present invention will be described using FIG. 9 to FIG.

  FIG. 9 is a perspective view showing the external appearance of the information transmitting apparatus 200, and FIG. 10 is an internal schematic diagram showing the configuration of the information transmitting apparatus 200. FIG. 11A is a side view of the main part of the information transmitting apparatus 200 as viewed from the right side (X1 side), and FIG. 11B shows the main part of the information transmitting apparatus 200 on the lower side ( It is a top view when it sees from the Z2 side. FIG. 12 is a schematic external view showing the operation of the information transmitting apparatus 200, and FIG. 13 is a cross-sectional view of the switch device 159 used in the information transmitting apparatus 200.

  The information transmission apparatus 200 shown in FIG. 9 is used for control of the distribution board, and is configured to be able to transmit information selected by the information transmission apparatus 200 to the outside. The information transmission apparatus 200 includes a selection unit 101 that can detect one of a plurality of selection states by operating a switch device 159 that constitutes the operation unit 151. The selection part 101 is arrange | positioned at the upper part of the box 191 shown in FIG.

  As illustrated in FIG. 10, the information transmission device 200 includes the selection unit 101, the selection determination unit 102, the power generation unit 103, the rectifier circuit 108, and the transmission unit 109 described above. Further, the selection unit 101 includes an operation panel 152, and the selection confirmation unit 102, the rectifier circuit 108, and the transmission unit 109 are attached to the upper surface of the operation panel 152, unlike the information transmission apparatus 100. The wiring board 211 is disposed on one surface (the surface on the Z2 side). In addition, a pressing shaft 161 is attached to the operation panel 152, and the pressing shaft 161 is connected to the operation member 115 in the power generation unit 103 via a connecting member 117. Then, the power generation unit 103 generates power by pressing the pressing shaft 161 downward. This operation is the same as that of the information transmitting apparatus 100.

  The selection confirmation unit 102, the rectifier circuit 108, the transmission unit 109, and the antenna 109a used for the transmission unit 109 formed on one surface (Z2 side surface) of the wiring board 211 are enlarged and illustrated. 11 (a) and FIG. 11 (b). The selection determination unit 102, the rectifier circuit 108, the transmission unit 109, and the antenna 109a disposed on the wiring board 211 are each formed of electronic components such as an integrated circuit. It may be formed of two integrated circuits. The antenna 109a is generally formed of a chip component, but may be formed of a copper foil pattern on the wiring board 211. Note that the connection relationship between these units and their functions are the same as those of the information transmitting apparatus 100, and thus description thereof will be omitted.

  As shown in FIG. 11A, a switch device 159 is formed on the other surface (the surface on the Z1 side) of the wiring board 211 by a plurality of operation buttons 159a. The configuration and operation of the switch device 159 will be described later.

  As described above, since the information transmitting apparatus 200 uses the switch device 159 having the plurality of operation buttons 159a as the operation unit 151, it can detect and output one of the plurality of selected states. it can. In addition, as described above, the power generation is performed by pressing the pressing shaft 161 attached to the operation panel 152. The operation will be described with reference to FIG. 9, FIG. 10, and FIG.

  The switch device 159 can select six different ON states from ON1 to ON6 by pressing one of the six operation buttons 159a downward. Further, when all the operation buttons 159a are not pressed, it is regarded as an OFF state. The switch device 159 is assumed to be a general push switch for easy understanding. However, the switch device 159 is not a push switch but an electrostatic sensor that performs a switching operation only by contact. A switch device may be used.

  Normally, as shown in FIGS. 9 and 12A, all the operation buttons 159a are not pressed, and the switch device 159 is OFF. Also, as shown in FIG. 12A, the vertical position of the operation unit 151 is at the upper position. At this time, as shown in FIG. 10, the position of the lower end of the pressing shaft 161 is at the upper part in the box body 191, so the position of the operation member 115 in the power generation unit 103 is also at the upper part. Therefore, power generation is not performed.

  Next, when trying to select the ON1 state by the information transmitting apparatus 200, as shown in FIG. 12B, the operation button 159a corresponding to ON1 among the operation buttons 159a is pressed. This is referred to as a first press. The switch device 159 having pressed the operation button 159a corresponding to ON1 for the first time selects the ON1 state. Even at this time, the position of the lower end of the pressing shaft 161 is at the upper part in the box 191, so that the position of the operation member 115 in the power generation unit 103 is also at the upper part. Therefore, power generation has not been performed yet. Therefore, so far, the selection confirmation unit 2 and the transmission unit 9 have stopped operating.

  Next, as shown in FIG. 12C, the operation button 159a is further pressed downward from the state where the operation button 159a is first pressed. This is referred to as a second press. At this time, the pressing shaft 161 shown in FIG. 10 is pressed downward. Therefore, the operation member 115 in the power generation unit 103 is pushed down via the connecting member 117, and the operation member 115 moves further to a position below the position shown in FIG. As a result, the power generation unit 103 generates power.

  Thus, when power generation is performed in the power generation unit 103, power is supplied to the selection confirmation unit 102 and the transmission unit 109, and the selection confirmation unit 102 and the transmission unit 109 start operating. As a result, information regarding selection is transmitted from the transmission unit 109 to the outside by radio. The operation of the power generation unit 103 is the same as that of the power generation unit 3 in the information transmitting apparatus 100, and thus the description thereof is omitted.

  Next, an example of the switch device 159 will be briefly described with reference to FIG. The switch device 159 is a push switch, which has an interlocking cam plate 217 and a frame plate 218 placed on a wiring board 211 having a fixed contact (not shown), and is provided on one side of the operation button 159a.
