Abstract
Description
[Technical field]
[0001] The present disclosure relates to a pulse generating device. [Background technology]
[0002] Generally, a meter for measuring the amount of electricity or other consumption generates a pulse each time the amount of electricity or other consumption reaches a certain amount. A monitoring device to which the meter is connected counts the number of pulses from the meter and displays the counted value on a display. Billing for the amount of electricity or other consumption is carried out based on the value displayed on the display of the monitoring device.
[0003] For example, Patent Document 1 discloses a related technique. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2019-219250 A Summary of the Invention [Problem to be solved by the invention]
[0005] If the power to the monitoring device is cut off due to a power outage or other reason, the monitoring device will no longer be able to count the number of pulses from the meter. Therefore, when the power to the monitoring device is restored, a maintenance technician must adjust the number of pulses counted by the monitoring device, i.e., the value displayed on the display, to the number of pulses output from the meter.
[0006] Conventionally, the required number of pulses would be generated by shorting the terminals to which the meter was connected with a jumper wire, and the monitoring device would count them. However, if it was necessary to generate 700 pulses, for example, the maintenance personnel would have to repeatedly touch each end of the jumper wire to the terminal to which the meter was connected 700 times. This created a problem of a heavy burden on the maintenance personnel.
[0007] The present disclosure has been made to solve the above-mentioned problems. An object of the present disclosure is to provide a pulse generating device that can reduce the burden on maintenance personnel who generate pulses. [Means for solving the problem]
[0008] The pulse generator according to the present disclosure is a pulse generator for adjusting the number of pulses counted by a monitoring device in a system including a meter that generates a pulse by closing a contact each time the amount of electricity, gas, or water used reaches a certain amount, and a monitoring device that counts the number of pulses generated by the meter. The pulse generator includes a first connection body for electrically connecting to a first electric wire extending from the contact, a second connection body for electrically connecting to a second electric wire extending from the contact, a support, a first movable body supported by the support so as to be manually operated to be able to move in a specific manner relative to the support, a first fixed terminal electrically connected to the first connection body, and a plurality of first movable terminals provided on the first movable body and electrically connected to the second connection body. The first movable body moves in a specific manner, causing the first fixed terminal to come into contact with the plurality of first movable terminals in sequence.

[0012] Hereinafter, a detailed description will be given with reference to the drawings. Duplicate descriptions will be appropriately simplified or omitted. In each drawing, the same reference numerals indicate the same or corresponding parts.
[0013] Embodiment 1 1 is a diagram showing an example of a monitoring system installed in a building. The monitoring system includes a meter 1 and a monitoring device 2. The monitoring device 2 includes a local device 3 and a central monitoring device 4.
[0014] The meter 1 is a device for measuring the amount of electricity, gas, or water used. In the following, an example in which the meter 1 is a device for measuring the amount of electricity used will be described. The meter 1 includes a rotating body 11, a contact 12, and a counter 13.
[0015] The contact 12 is, for example, a mechanical contact. An electric wire 14 and an electric wire 15 extend from the contact 12. The electric wire 14 and the electric wire 15 are connected to the local device 3. The rotor 11 rotates according to the amount of electricity used. When the rotor 11 rotates once, the contact 12 closes once. That is, in the meter 1, the contact 12 closes and a pulse is generated every time the amount of electricity used reaches a certain amount. The number of pulses generated by the meter 1 is displayed on the counter 13.
[0016] The pulses generated by the meter 1 are input to the local device 3. The local device 3 counts the number of pulses generated by the meter 1. The local device 3 transmits information indicating the number of counted pulses to the central monitoring device 4 via a transmission line 5.
[0017] 1 shows an example in which the local device 3 includes multiple connection terminals 31. One of the connection terminals 31 is electrically connected to an electric wire 14. In the following, this connection terminal is given the reference symbol 31a to distinguish it from the other connection terminals 31. The other connection terminal 31 is electrically connected to an electric wire 15. In the following, this connection terminal is given the reference symbol 31b to distinguish it from the other connection terminals 31.
[0018] The central monitoring device 4 includes a display 41. The central monitoring device 4 displays on the display 41 the number of pulses counted by the local devices 3.
[0019] In the monitoring system shown in Fig. 1, if the power supply of the monitoring device 2 is cut off due to a power outage or the like, the monitoring device 2 will be unable to count the number of pulses from the meter 1. In such a case, after the power supply of the monitoring device 2 is restored, a maintenance person must go to the site and perform an adjustment work to match the number of pulses counted by the monitoring device 2 to the number of pulses output from the meter 1. That is, in this adjustment work, the maintenance person makes the value displayed on the display 41 coincide with the value displayed on the counter 13. Below, a pulse generating device 6 used to adjust the number of pulses counted by the monitoring device 2 in the monitoring system will be described.
[0020] 2 is a diagram showing an example of a pulse generating device 6 in the first embodiment. The pulse generating device 6 is a device for generating a pulse similar to a pulse generated by closing the contact 12, without closing the contact 12. The pulse generating device 6 includes a connecting body 61, a connecting body 62, a support 63, a movable body 64, a plurality of fixed terminals 65, and one movable terminal 66.
[0021] The support 63 is a member for supporting other components provided in the pulse generating device 6. As an example, the support 63 is box-shaped. If the support 63 is box-shaped, the movable body 64, the multiple fixed terminals 65, and the movable terminal 66 are housed inside the support 63. As another example, the support 63 is plate-shaped. If the support 63 is plate-shaped, the movable body 64, the multiple fixed terminals 65, and the movable terminal 66 are disposed on one surface side of the support 63. The support 63 may have other shapes.
[0022] The connector 61 is a member for electrically connecting to the electric wire 14. FIG. 2 shows an example in which the connector 61 includes a clip 61a, an electric wire 61b, and a rod-shaped conductor 61c. The conductor 61c is provided on the support 63 and arranged along the X-axis. The X-axis is an axis parallel to a specific surface of the support 63. One end of the electric wire 61b is connected to one end of the conductor 61c. That is, the electric wire 61b extends from the conductor 61c to the outside of the support 63. The clip 61a is connected to the other end of the electric wire 61b. The clip 61a is detachable from the connection terminal 31a. The connector 61 is electrically connected to the electric wire 14 by attaching the clip 61a to the connection terminal 31a.
[0023] The connector 62 is a member for electrically connecting to the electric wire 15. FIG. 2 shows an example in which the connector 62 includes a clip 62a, an electric wire 62b, and a rod-shaped metal rail 62c. The rail 62c is provided on the support 63 and arranged along the X-axis. That is, the conductor 61c and the rail 62c are arranged in parallel. One end of the electric wire 62b is connected to one end of the rail 62c. That is, the electric wire 62b extends from the rail 62c to the outside of the support 63. The clip 62a is connected to the other end of the electric wire 62b. The clip 62a is detachable from the connection terminal 31b. The connector 62 is electrically connected to the electric wire 15 by attaching the clip 62a to the connection terminal 31b.
[0024] The movable body 64 is a member that is manually operated by a maintenance worker to generate a pulse. The movable body 64 is supported by the support 63 so that it can be manually operated to perform a specific movement relative to the support 63. FIG. 2 shows an example in which the movable body 64 is movable along the rail 62c on the rail 62c. That is, in the example shown in FIG. 2, the movable body 64 is movable along the X-axis. FIG. 2 shows an example in which the specific movement is a linear reciprocating movement.
[0025] The movable terminal 66 is provided on the movable body 64. The movable terminal 66 is, for example, a plate-shaped metal member. The movable terminal 66 may be a leaf spring. The movable terminal 66 is disposed so that its normal line is parallel to the X-axis, and protrudes from the movable body 64 so as to approach the conductor 61c. The movable terminal 66 is electrically connected to the connecting body 62. Since the movable terminal 66 is provided on the movable body 64, it moves together with the movable body 64. In the example shown in FIG. 2, the movable terminal 66 moves back and forth along the X-axis while maintaining a conductive state with the connecting body 62.
[0026] 2 shows an example in which the movable body 64 is supported by the support body 63 via a rail 62c. This is just one example. For example, the movable body 64 may be directly supported by the support body 63 by connecting the electric wire 62b to the movable terminal 66 without using the rail 62c. The method of supporting the movable body 64 and the method of electrical connection between the connecting body 62 and the movable terminal 66 are not limited to the above example.
[0027] The multiple fixed terminals 65 are provided on the support 63. FIG. 2 shows an example in which the multiple fixed terminals 65 are fixed to the conductor 61c, and thereby provided on the support 63 via the conductor 61c. The multiple fixed terminals 65 may be provided directly on the support 63. Each fixed terminal 65 is, for example, a plate-shaped metal member. Each fixed terminal 65 is arranged such that its normal line is parallel to the X-axis, and protrudes from the conductor 61c so as to approach the rail 62c. Moreover, the multiple fixed terminals 65 are arranged side by side along the X-axis at equal intervals, as shown in FIG. 2. Each of the multiple fixed terminals 65 is electrically connected to the connector 61.
[0028] When viewed from the X-axis direction, the movable terminal 66 is disposed so that its tip portion overlaps each of the multiple fixed terminals 65. Therefore, in the above adjustment work, when a maintenance person attaches clip 61a to connection terminal 31a and clip 62a to connection terminal 31b, a pulse can be generated simply by moving the movable body 64. When the movable body 64 performs a specific movement, that is, when the movable body 64 moves along the X-axis, the movable terminal 66 comes into contact with the multiple fixed terminals 65 in order, and a pulse is generated every time the movable terminal 66 comes into contact with the fixed terminal 65.
[0029] By using the pulse generator 6 shown in Fig. 2, the burden on the maintenance personnel who generate the pulses during the above adjustment work can be reduced. Conventional adjustment work using jumper wires has problems such as the operator's hand being easily misaligned and the occurrence of false pulses. By using the pulse generator 6, the occurrence of false pulses can also be significantly reduced.
[0030] In addition, the pulse generator 6 is effective when the above adjustment work must be performed in a small space, since it can generate pulses simply by sliding the movable body 64. Furthermore, the pulse generator 6 does not require a power source and does not use a battery, so it can be easily miniaturized and is highly portable.
[0031] In the example shown in Fig. 2, a pulse is generated whether the movable body 64 is slid to the right or to the left along the X-axis. As another example, a pulse may be generated only when the movable body 64 slides to one side along the X-axis, and no pulse may be generated when the movable body 64 slides to the other side. Such a function can be realized, for example, in the example shown in Fig. 2, by exposing metal only on the surface of the movable terminal 66 facing the right side, and covering the other surfaces, including the surface facing the left side, with an insulator.
[0032] In the above adjustment work, the maintenance person who operates the pulse generator 6 and the maintenance person who checks the display on the display 41 communicate with each other to make the value displayed on the display 41 completely coincide with the value displayed on the counter 13. Therefore, in the final stage of the adjustment work, the maintenance person who operates the pulse generator 6 needs to generate pulses little by little while finely adjusting the movable body 64. In order to make it easier to grasp the timing of pulse generation, the pulse generator 6 may be configured so that the maintenance person can visually check the position of the movable terminal 66 relative to the fixed terminal 65. For example, if the support body 63 is box-shaped, a transparent member may be used for a part or the whole of the support body 63 so that the maintenance person can check the contact state between the fixed terminal 65 and the movable terminal 66.
[0033] The pulse generating device 6 may further include a changeover switch 67 as shown in FIG. 2. FIG. 2 shows an example in which the changeover switch 67 is provided in the middle of the electric wire 61b. The changeover switch 67 is a switch for switching between a conductive state and a cutoff state. The conductive state is a state in which the connector 61 and the connector 62 are conductive when the movable terminal 66 contacts any of the multiple fixed terminals 65. The cutoff state is a state in which the connector 61 and the connector 62 are not conductive even if the movable terminal 66 contacts any of the multiple fixed terminals 65. The changeover switch 67 may be a slide switch or a button switch. The changeover switch 67 may be another type of switch. A maintenance person may simply keep the changeover switch 67 in the cutoff state when it is not necessary to generate a pulse. This can further reduce the occurrence of false pulses.
[0034] Other examples of the pulse generating device 6 will be described below. In the following, the same configurations and functions as those described above will not be described. In the examples shown below, if the configurations or functions described above can be adopted, they may be adopted as appropriate. If the configurations or functions described below can be adopted in combination, they may be adopted as appropriate.
[0035] Fig. 3 is a diagram showing another example of the pulse generator 6 in the embodiment 1. While Fig. 2 shows a slide-type pulse generator 6, Fig. 3 shows a dial-type pulse generator 6. The pulse generator 6 shown in Fig. 3 includes a connector 61, a connector 62, a support 63, a movable body 68, one fixed terminal 69, and multiple movable terminals 70.
[0036] The support 63 is a member for supporting other components provided in the pulse generating device 6.
[0037] The connecting body 61 is a member for electrically connecting to the electric wire 14. Fig. 3 shows an example in which the connecting body 61 includes a clip 61a, an electric wire 61b, and a rod-shaped conductor 61c, similar to the example shown in Fig. 2. The conductor 61c is provided on a support 63. The connecting body 61 is electrically connected to the electric wire 14 by attaching the clip 61a to the connection terminal 31a.
[0038] The connector 62 is a member for electrically connecting to the electric wire 15. Fig. 3 shows an example in which the connector 62 includes a clip 62a, an electric wire 62b, and a metallic conductive plate 62d. The conductive plate 62d is provided on the support 63. One end of the electric wire 62b is connected to the conductive plate 62d. That is, the electric wire 62b extends from the conductive plate 62d to the outside of the support 63. The connector 62 is electrically connected to the electric wire 15 by attaching the clip 62a to the connection terminal 31b.
[0039] The movable body 68 is a member that is manually operated by a maintenance worker to generate a pulse. The movable body 68 is supported by the support 63 so that a specific movement relative to the support 63 can be achieved by manually operating the movable body 68. Fig. 3 shows an example in which the movable body 68 is rotatable about an axis 71. The axis 71 is perpendicular to the conductive plate 62d, for example. Fig. 3 shows an example in which the specific movement is a rotational movement in both directions (directions indicated by arrow Y).
[0040] The multiple movable terminals 70 are provided on the movable body 68. The movable terminals 70 are, for example, plate-shaped metal members. The multiple movable terminals 70 are arranged radially around the shaft 71 so as to protrude outward from the movable body 68 at equal intervals. Each of the multiple movable terminals 70 is electrically connected to the connecting body 62. Since the movable terminals 70 are provided on the movable body 68, they move together with the movable body 68. In the example shown in FIG. 3, the movable terminals 70 rotate in both directions around the shaft 71 while maintaining a conductive state with the connecting body 62.
[0041] 3 shows an example in which the movable body 68 is supported by the support body 63 via a conductive plate 62d. This is just one example. For example, another configuration may be adopted that can ensure electrical continuity between the connection body 62 and the movable terminal 70 while directly supporting the movable body 68 on the support body 63. The method of supporting the movable body 68 and the method of electrical continuity between the connection body 62 and the movable terminal 70 are not limited to the above example.
[0042] The fixed terminal 69 is provided on the support 63. FIG. 3 shows an example in which the fixed terminal 69 is fixed to the conductor 61c, and thereby provided on the support 63 via the conductor 61c. The fixed terminal 69 may be provided directly on the support 63. The fixed terminal 69 is, for example, a plate-shaped metal member. The fixed terminal 69 may also be a leaf spring. The fixed terminal 69 is disposed such that its normal line is parallel to the X-axis, and protrudes from the conductor 61c so as to approach the axis 71. The fixed terminal 69 is electrically connected to the connecting body 61.
[0043] The fixed terminal 69 is arranged so that its tip portion can overlap each of the multiple movable terminals 70 when viewed from the X-axis direction perpendicular to the axis 71. That is, when the movable body 68 rotates and a certain movable terminal 70 approaches the fixed terminal 69 closest, the tip portion of the fixed terminal 69 overlaps the tip portion of the movable terminal 70 when viewed from the X-axis direction. Therefore, when the maintenance person attaches the clip 61a to the connection terminal 31a and the clip 62a to the connection terminal 31b in the above adjustment work, a pulse can be generated simply by moving the movable body 68. When the movable body 68 performs a specific movement, that is, when the movable body 68 rotates around the axis 71, the fixed terminal 69 comes into contact with the multiple movable terminals 70 in order, and a pulse is generated every time the fixed terminal 69 comes into contact with the movable terminal 70.
[0044] When the pulse generator 6 shown in Fig. 3 is used, the same effect as when the pulse generator 6 shown in Fig. 2 is used can be obtained. In the pulse generator 6 shown in Fig. 3, for example, if the support 63 is box-shaped, a transparent member may be used for part or all of the support 63 so that a maintenance person can check the contact state between the fixed terminal 69 and the movable terminal 70.
[0045] In the example shown in Fig. 3, a pulse is generated whether the movable body 68 is rotated clockwise or counterclockwise around the axis 71. As another example, a pulse may be generated only when the movable body 68 rotates in one direction around the axis 71, and no pulse may be generated when the movable body 68 rotates in the other direction. Such a function can be realized, for example, in the example shown in Fig. 3, by exposing metal only on the surface of the movable terminal 70 that faces the fixed terminal 69 when approaching it from the right side, and covering the other surfaces, including the surface that faces the fixed terminal 69 when approaching it from the left side, with an insulator.
[0046] In the example shown in Fig. 3, the pulse generating device 6 may further include a change-over switch 67. In the example shown in Fig. 3, the conductive state is a state in which the connecting body 61 and the connecting body 62 are conductive when the fixed terminal 69 contacts any of the multiple movable terminals 70. The cut-off state is a state in which the connecting body 61 and the connecting body 62 are not conductive even if the fixed terminal 69 contacts any of the multiple movable terminals 70. This can further reduce the occurrence of false pulses.
[0047] As shown in FIG. 3, the pulse generating device 6 may further include a movable body 72, one fixed terminal 73, and one movable terminal 74.
[0048] The movable body 72 is a member that is manually operated by a maintenance worker to generate a pulse. The movable body 72 is supported by the support 63 so that it can be manually operated to perform a specific movement relative to the support 63. From the viewpoint of operability, it is preferable that the movement of the movable body 72 is the same as the movement of the movable body 68. FIG. 3 shows an example in which the movable body 72 is rotatable around an axis 75. The axis 75 is parallel to the axis 71. FIG. 3 shows an example in which the specific movement is a rotational movement in both directions.
[0049] The movable terminal 74 is provided on the movable body 72. The movable terminal 74 is a plate-shaped metal member similar to the movable terminal 70. The movable terminal 74 is arranged so as to protrude outward from the movable body 72. The movable terminal 74 is electrically connected to the connecting body 62. Since the movable terminal 74 is provided on the movable body 72, it moves together with the movable body 72. In the example shown in FIG. 3, the movable terminal 74 rotates in both directions around the axis 75 while maintaining a conductive state with the connecting body 62.
[0050] 3 shows an example in which the movable body 72 is supported by the support body 63 via a conductive plate 62d. This is just one example. For example, another configuration may be adopted that can ensure electrical continuity between the connection body 62 and the movable terminal 74 while directly supporting the movable body 72 on the support body 63. The method of supporting the movable body 72 and the method of electrical continuity between the connection body 62 and the movable terminal 74 are not limited to the above example.
[0051] The fixed terminal 73 is provided on the support 63. FIG. 3 shows an example in which the fixed terminal 73 is fixed to the conductor 61c, and thereby provided on the support 63 via the conductor 61c. The fixed terminal 73 may be provided directly on the support 63. The fixed terminal 73 is, for example, a plate-shaped metal member. The fixed terminal 73 may be a leaf spring. The fixed terminal 73 is disposed such that its normal line is parallel to the X-axis, and protrudes from the conductor 61c so as to approach the axis 75. The fixed terminal 73 is electrically connected to the connecting body 61.
[0052] The fixed terminal 73 is disposed so that its tip portion can overlap the movable terminal 74 when viewed from the X-axis direction perpendicular to the axis 75. That is, when the movable body 72 rotates and the movable terminal 74 approaches the fixed terminal 73 closest to the fixed terminal 73, the tip portion of the fixed terminal 73 overlaps the tip portion of the movable terminal 74 when viewed from the X-axis direction. Therefore, when the maintenance person attaches the clip 61a to the connection terminal 31a and the clip 62a to the connection terminal 31b in the above adjustment work, a pulse can be generated simply by moving the movable body 72. When the movable body 72 performs a specific movement, that is, when the movable body 72 rotates around the axis 75, the fixed terminal 73 comes into contact with the movable terminal 74, and a pulse is generated every time the fixed terminal 73 comes into contact with the movable terminal 74.
[0053] FIG. 3 shows an example in which ten movable terminals 70 are provided on the movable body 68, and one movable terminal 74 is provided on the movable body 72. The number of movable terminals 70 provided on the movable body 68 is not limited to ten. The number of movable terminals 74 provided on the movable body 72 is not limited to one. The number of movable terminals 74 provided on the movable body 72 may be less than the number of movable terminals 70 provided on the movable body 68. For example, a plurality of movable terminals 74 may be provided on the movable body 72. In such a case, each of the plurality of movable terminals 74 is electrically connected to the connection body 62. Then, when the movable body 72 rotates around the axis 75, the fixed terminal 73 comes into contact with the plurality of movable terminals 74 in order, and a pulse is generated each time the fixed terminal 73 comes into contact with the movable terminal 74.
[0054] In such an example, when it is desired to generate many pulses, the movable body 68 is rotated, and when it is desired to generate pulses little by little, the movable body 72 is rotated.
[0055] As shown in FIG. 3, the pulse generating device 6 may further include a movable body 76 and a transmission mechanism 77.
[0056] The movable body 76 is a member that is manually operated by a maintenance worker to generate a pulse. The movable body 76 is supported by the support 63 so that a specific movement can be made with respect to the support 63 by being manually operated. From the viewpoint of operability, it is preferable that the movement of the movable body 76 is the same as the movement of the movable body 68 and the movement of the movable body 72. FIG. 3 shows an example in which the movable body 76 is rotatable around an axis 78. The axis 78 is parallel to the axis 71. The axis 78 is also parallel to the axis 75. FIG. 3 shows an example in which the specific movement is a rotational movement in both directions.
[0057] The transmission mechanism 77 transmits the power of the movable body 76 to the movable body 68 so that the rotation speed of the movable body 68 is greater than the rotation speed of the movable body 76 when the movable body 76 rotates. For example, when the movable body 76 rotates once, the movable body 68 rotates twice. When the movable body 76 rotates once, the movable body 68 may rotate ten times. The ratio between the number of rotations of the movable body 76 and the number of rotations of the movable body 68 is set arbitrarily. FIG. 3 shows an example in which a belt is used for the transmission mechanism 77. Gears may also be used for the transmission mechanism 77. Other mechanisms for transmitting power may also be used for the transmission mechanism 77.
[0058] The pulse generator 6 may further include a counter 79 and a reset button 80, as shown in FIG.
[0059] It is preferable that the counter 79 is a mechanical counter that does not require a power source. As an example, the number of pulses generated by the pulse generator 6 is displayed on the counter 79. The counter 79 may also display the number of rotations of the movable body 68 or the number of rotations of the movable body 76. By pressing the reset button 80, the display on the counter 79 can be reset to 0.
[0060] In the above, an example has been described in which the number of terminals on the fixed side (fixed terminals 65) is greater than the number of terminals on the movable side (movable terminals 66) for the slide-type pulse generator 6 shown in Fig. 2. Also, an example has been described in which the number of terminals on the movable side (movable terminals 70) is greater than the number of terminals on the fixed side (fixed terminals 69) for the dial-type pulse generator 6 shown in Fig. 3. These are just examples.
[0061] Fig. 4 is a diagram showing another example of the pulse generating device 6. Fig. 4 shows a main part of the sliding type pulse generating device 6. As shown in Fig. 4, the sliding type pulse generating device 6 may be provided with one fixed terminal 65 and multiple movable terminals 66.
[0062] In the example shown in FIG. 4, the fixed terminal 65 is, for example, a leaf spring. The fixed terminal 65 is arranged so that its normal line is parallel to the X-axis, and protrudes from the conductor 61c so as to approach the rail 62c. The multiple movable terminals 66 are provided on the movable body 64 and move integrally with the movable body 64. The multiple movable terminals 66 are arranged in a line along the X-axis at equal intervals as shown in FIG. 4. Each of the multiple movable terminals 66 is electrically connected to the connection body 62. Then, when the movable body 64 makes a specific movement, that is, when the movable body 64 moves along the X-axis, the fixed terminal 65 comes into contact with the multiple movable terminals 66 in order, and a pulse is generated each time the fixed terminal 65 comes into contact with the movable terminal 66.
[0063] Fig. 5 is a diagram showing another example of the pulse generating device 6. Fig. 5 shows a main part of the dial-type pulse generating device 6. As shown in Fig. 5, the dial-type pulse generating device 6 may be provided with a plurality of fixed terminals 69 and one movable terminal 70.
[0064] In the example shown in FIG. 5, the movable terminal 70 is, for example, a leaf spring. The movable terminal 70 is arranged so as to protrude outward from the movable body 68. The multiple fixed terminals 69 are arranged radially at equal intervals around the axis 71. Each of the multiple fixed terminals 69 is electrically connected to the connection body 61. Then, when the movable body 68 performs a specific movement, that is, when the movable body 68 rotates around the axis 71, the movable terminal 70 contacts the multiple fixed terminals 69 in order, and a pulse is generated every time the movable terminal 70 contacts the fixed terminal 69. Note that, in the example shown in FIG. 5, it is sufficient that the number of fixed terminals 73 that can contact the movable terminal 74 is less than the number of fixed terminals 69 that can contact the movable terminal 70.
[0065] In this embodiment, an example has been described in which the dial-type pulse generator 6 shown in Fig. 3 includes a movable body 68 for continuously generating pulses and a movable body 72 for generating pulses little by little. A similar function may be provided in the slide-type pulse generator 6 shown in Fig. 2.
[0066] Fig. 6 is a diagram showing another example of a pulse generating device 6. Fig. 6 shows a main part of a sliding type pulse generating device 6. As shown in Fig. 6, the sliding type pulse generating device 6 may further include a movable body 81, one fixed terminal 82, and one movable terminal 83.
[0067] In the example shown in FIG. 6, the connector 61 further includes a rod-shaped conductor 61d. The conductor 61d is provided on the support 63 and arranged along the X-axis. That is, the conductor 61d is arranged parallel to the conductor 61c. In the example shown in FIG. 6, both the conductors 61c and 61d are connected to the electric wire 61b. The connector 62 further includes a rod-shaped metal rail 62e. The rail 62e is provided on the support 63 and arranged along the X-axis. That is, the rails 62c and 62e are arranged parallel to each other. In the example shown in FIG. 6, both the rails 62c and 62e are connected to the electric wire 62b.
[0068] The movable body 81 is a member that is manually operated by a maintenance worker to generate a pulse. The movable body 81 is supported by the support 63 so that it can perform a specific movement relative to the support 63 by being manually operated. From the viewpoint of operability, it is preferable that the movement of the movable body 81 is the same as the movement of the movable body 64. FIG. 6 shows an example in which the movable body 81 is movable along the rail 62e on the rail 62e. That is, in the example shown in FIG. 6, the movable body 81 is movable along the X-axis. FIG. 6 shows an example in which the specific movement is a linear reciprocating movement.
[0069] The movable terminal 83 is provided on the movable body 81. The movable terminal 83 is a plate-shaped metal member similar to the movable terminal 66. The movable terminal 83 may be a leaf spring. The movable terminal 83 is disposed so that its normal line is parallel to the X-axis, and protrudes from the movable body 81 so as to approach the conductor 61d. The movable terminal 83 is electrically connected to the connecting body 62. Since the movable terminal 83 is provided on the movable body 81, it moves together with the movable body 81. In the example shown in FIG. 6, the movable terminal 83 moves back and forth along the X-axis while maintaining a conductive state with the connecting body 62.
[0070] 6 shows an example in which the movable body 81 is supported by the support body 63 via a rail 62e. The movable body 81 may be directly supported by the support body 63. The method of supporting the movable body 81 and the method of electrical connection between the connection body 62 and the movable terminal 83 are not limited to the above example.
[0071] The fixed terminal 82 is provided on the support 63. Fig. 6 shows an example in which the fixed terminal 82 is fixed to the conductor 61d, and thereby provided on the support 63 via the conductor 61d. The fixed terminal 82 is, for example, a plate-shaped metal member. The fixed terminal 82 is disposed such that its normal line is parallel to the X-axis, and protrudes from the conductor 61d so as to approach the rail 62e. The fixed terminal 82 is electrically connected to the connecting body 61.
[0072] The movable terminal 83 is disposed so that its tip portion overlaps the fixed terminal 82 when viewed from the X-axis direction. Therefore, in the above-mentioned adjustment work, when a maintenance person attaches clip 61a to connection terminal 31a and clip 62a to connection terminal 31b, a pulse can be generated simply by moving the movable body 81. When the movable body 81 makes a specific movement, that is, when the movable body 81 moves along the X-axis, the movable terminal 83 comes into contact with the fixed terminal 82, and a pulse is generated every time the movable terminal 83 comes into contact with the fixed terminal 82.
[0073] FIG. 6 shows an example in which ten fixed terminals 65 are provided on the conductor 61c, and one fixed terminal 82 is provided on the conductor 61d. The number of fixed terminals 65 provided on the conductor 61c is not limited to ten. The number of fixed terminals 82 provided on the conductor 61d is not limited to one. The number of fixed terminals 82 provided on the conductor 61d may be less than the number of fixed terminals 65 provided on the conductor 61c. For example, a plurality of fixed terminals 82 may be provided on the conductor 61d. In this case, each of the plurality of fixed terminals 82 is electrically connected to the connecting body 62. Then, when the movable body 81 moves along the X-axis, the movable terminal 83 comes into contact with the plurality of fixed terminals 82 in order, and a pulse is generated every time the movable terminal 83 comes into contact with the fixed terminal 82.
