Description

  The present invention relates to a vibration detection apparatus including a rolling element that rolls due to vibration such as an earthquake, and switch means that operates according to the rolling of the rolling element.

  Conventionally, vibration detection devices having various configurations have been proposed as vibration detection devices that detect vibrations such as earthquakes. For example, in the vibration detection device described in Patent Literature 1, a mounting unit on which a sphere is mounted, a donut-shaped movable contact disposed around the mounting unit, and the upper surface of the movable contact is the upper surface of the mounting unit. And a spring that elastically biases the movable contact so as to form a concave surface, a fixed contact disposed below the movable contact, and a tapered portion that is disposed outside the movable contact and forms a common concave surface with the upper surface of the movable contact With. When the sphere rolls over the movable contact to the tapered portion due to an earthquake or the like, the tapered portion functions to return the sphere to the mounting portion. When the sphere rolls on the concave surface due to an earthquake or the like, the movable contact is lowered against the elastic force of the spring by its own weight while the sphere rolls on the movable contact. As a result, while the rolling sphere is temporarily placed on the movable contact, the movable contact descends and contacts the fixed contact. A detection signal is given to the control circuit by the contact between the movable contact and the fixed contact, and the wiring breaker is activated.

Utility Model Registration No. 3026542

  In the vibration detection device described in Patent Literature 1, when vibration such as an earthquake stops, the sphere returns to the placement portion by its own weight along the concave surface formed by the placement portion, the movable contact, and the taper portion. Therefore, there is an advantage that the structure for returning the sphere is not complicated. However, in the vibration detection device described in Patent Document 1, the movable contact is brought into contact with the fixed contact against the elastic force of the spring while the sphere rolls on the movable contact. Subtle settings or adjustments need to be made for a number of factors such as the weight of the sphere, the elastic force of the spring, and the distance between the movable contact and the fixed contact. In addition, when the vibration such as an earthquake is large, the sphere rolls over the movable contact to the tapered portion, and therefore, the movable contact may not be reliably brought into contact with the fixed contact in the initial stage of the vibration. For this reason, there exists a problem which cannot detect a vibration, such as an earthquake, at an early stage, and can operate a circuit breaker.

  Therefore, the present invention has been made in view of the above circumstances, and eliminates the work of returning the rolling elements to be placed on the mounting surface after stopping the vibration such as an earthquake, and reliably detects the vibration such as an earthquake. An object of the present invention is to provide a vibration detection device that can perform the above-described operation.

[Electrical configuration of lighting device 1 for sliding door]
With reference to FIG. 7 and FIG. 8, the electrical configuration of the lighting device 1 for a sliding door will be described. FIG. 7 is a circuit diagram showing a part of the electrical configuration of the earthquake detection device 22, and FIG. 8 is a circuit diagram showing another part of the electrical configuration of the earthquake detection device 22. The electrical configuration of the earthquake detection device 22 includes a control board 35 shown in FIG. 7, and an LED board 32 and a switch board 52 shown in FIG.

  The control board 35 has three connectors 80, 81 and 82. The connector 80 is coupled to a connector connected to an output terminal of the rectifying board of the sliding door power generator 20 via a connection line. The connector 81 is coupled to a connector 65 mounted on the switch board 52 via a connection line.

The reset switch RTSW is closed while the user is pressing, and supplies the power supply voltage from the power supply terminal VCC to the gate of the transistor ETR2. The reset switch RTSW is opened when the user releases the pressing operation, and stops supplying the power supply voltage to the gate of the transistor ETR2.

  The reset IC 90 has an input terminal RT1, a ground terminal RT2, and an output terminal RT3. The reset IC 90 outputs a reset signal from the output terminal RT3 when the voltage input to the input terminal RT1 is equal to or higher than a predetermined value, and outputs a reset signal when the voltage input to the input terminal RT1 does not reach the predetermined value. Is not output from the output terminal RT3, and is a known circuit element. The input terminal RT1 is connected to the power supply terminal VCC, and the ground terminal RT2 is grounded.

  One end of the resistor RC2 is connected to the power supply terminal VCC, and the other end of the resistor RC2 is connected to the drain of the field effect transistor ETR3.

A noise removing capacitor C3 is connected between the gate and the source of the transistor ETR4.

  When the reset signal is not supplied from the output terminal RT3 to the gate of the transistor ETR3, the transistor ETR3 is turned off, and the current from the drain to the source is cut off. When the reset signal is supplied from the output terminal RT3 to the gate of the transistor ETR3, the transistor ETR3 is turned on, and a current flows from the drain to the source.

  In the switch board 52 shown in FIG. 8, the fixed contact forming piece 61 and the fixed contact forming piece 63 are commonly connected to the terminal ST <b> 1 of the connector 65.

[Operation and Action of First Embodiment]
With reference to FIG. 9 and FIG. 10, operation | movement and an effect | action of the illuminating device 1 for sliding doors are demonstrated. FIG. 9 shows a state in which a part of the sphere 70 is fitted in the recess 59 </ b> A of the mounting table 58 and the sphere 70 is stationary on the mounting surface 59 in a normal state where no earthquake has occurred. FIG. 10 shows a state in which the sphere 70 rolls on the inclined surface 60A and contacts the upper connecting portion 61C and the leg portion 62A in an emergency state in which an earthquake occurs. In a normal state in which no earthquake has occurred, the sliding door opening / closing device 2 operates by receiving power supply from a commercial power source. When human approach is detected, the slide door opening / closing device 2 drives the electric motor to open and close both the slide doors 3A, 3B. By the opening / closing operation of the sliding door 3A, the generator of the sliding door power generator 20 generates an alternating voltage. This AC voltage is rectified into a DC voltage by the rectifying substrate in the sliding door power generator 20 and supplied between the terminals CT11 and CT12 of the connector 80. The supplied DC voltage is stored by the capacitor CND.

(Normal state with no earthquake)
In a normal state, since the sphere 70 is stationary on the mounting surface 59, the two fixed contact forming pieces 61 and 62 are electrically disconnected without being short-circuited, and both the fixed contact forming pieces 63, 64 is also electrically disconnected without being short-circuited. As a result, in a normal state, both the fixed contact forming pieces 61 and 62 and the fixed contact forming pieces 63 and 64 shown in FIG. 8 are both open. In this open state, since the power supply voltage from the power supply terminal VCC is not supplied to the gate of the transistor ETR1, the transistor ETR1 maintains the off state. Due to the off state of the transistor ETR1, the power supply voltage from the power supply terminal VCC is not supplied to the light emitting die auto D1 to D6. In a normal state, the power supply voltage from the power supply terminal VCC is not consumed by the light emitting dies auto D1 to D6. Therefore, the power generated by the generator by the opening / closing operation of the slide door 3A continues to be charged in the storage capacitor CND.

  When the power supply voltage is supplied from the storage capacitor CND to the reset IC 90 through the power supply terminal VCC, and the supplied power supply voltage is equal to or higher than a predetermined value, the reset IC 90 outputs a reset signal from the output terminal RT3. The reset signal is supplied to the gate of the transistor ETR3, and the transistor ETR3 maintains the on state. While the transistor ETR3 is in the ON state, the power supply voltage supplied from the power supply terminal VCC via the resistor RC2 is supplied between the drain and the source of the transistor ETR3, and the gate potential of the transistor ETR4 is maintained at a low potential. The For this reason, the transistor ETR4 is maintained in the off state.

  In the normal state, since the user does not press the reset switch RTSW, the reset switch RTSW maintains the open state. For this reason, the supply of the power supply voltage from the power supply terminal VCC to the gate of the transistor ETR2 is stopped by the reset switch RTSW. As a result, the transistor ETR2 is also kept off.

(Emergency state with earthquake)
When an earthquake occurs, the sphere 70 starts rolling from the mounting surface 59 of the mounting table 58 along one of the inclined surfaces 60A and 60B, and above the mounting surface 59 and both inclined surfaces 60A and 60B. Reciprocates left and right while rolling. When the earthquake vibration reaches a strong vibration equal to or higher than a predetermined vibration, the sphere 70 comes into contact with one of the fixed contact forming pieces 62 and 64. For example, when the sphere 70 rolls over the left upper end portion 60A-1 of the inclined surface 60A and comes into contact with the leg portion 62A of the fixed contact forming piece 62, as shown in FIG. The inclined contact surface of the upper connecting portion 61C of the forming piece 61 and the side surface of the leg portion 62A of the fixed contact forming piece 62 are contacted to short-circuit both the fixed contact forming pieces 61 and 62. As a result, the space between the fixed contact forming pieces 61 and 62 shown in FIG. 8 is closed. On the other hand, the space between the fixed contact forming pieces 63 and 64 shown in FIG. 8 remains open.

  When the space between the fixed contact forming pieces 61 and 62 is closed, the power supply voltage is supplied from the power supply terminal VCC to the resistor RC1 through the fixed contact forming pieces 61 and 62, and the power supply voltage is supplied to the gate of the transistor ETR1 through the resistor RC1. Supplied. As a result, the transistor ETR1 is turned on, and the power supply voltage from the power supply terminal VCC is supplied to the light emitting die autos D1 to D6. The light emitting diodes D1 to D6 are turned on to illuminate the periphery of the slide doors 3A and 3B. When a strong earthquake occurs, the power supply from the commercial power supply may be stopped. Therefore, by turning on the light-emitting diodes D1 to D6, the customers remaining inside the store are moved to the slide doors 3A and 3B. The customer can go out by manually opening the sliding doors 3A and 3B.

  In addition, when the space between the fixed contact forming pieces 61 and 62 is closed and the transistor ETR1 is once turned on, the power supply current from the power supply terminal VCC flows from the emitter of the transistor BTR to the base and passes through the drain and source of the transistor ETR1. To the ground side. As a result, the transistor BTR changes to the on state, and continues to supply the power supply voltage from the power supply terminal VCC to the gate of the transistor ETR1.

  After the spherical body 70 abuts against the fixed contact forming piece 62 and short-circuits both the fixed contact forming pieces 61 and 62 as shown in FIG. The space between the forming pieces 61 and 62 is opened. Therefore, both the fixed contact forming pieces 61 and 62 and both the fixed contact forming pieces 63 and 64 are opened, and the power supply voltage from the power supply terminal VCC is applied to the gate of the transistor ETR1 through the resistor RC1. It will not be supplied. However, since the transistor BTR is in the on state, the transistor BTR continues to supply the power supply voltage to the gate of the transistor ETR1. As a result, even after the fixed contact forming pieces 61 and 62 are opened, the transistor ETR1 continues to supply the power supply voltage to the light emitting diodes D1 to D6, and the light emitting diodes D1 to D6 continue to be lit.

  When the sphere 70 rolls over the upper right end portion 60B-1 of the inclined surface 60B and comes into contact with the leg portion 64A of the fixed contact forming piece 64, the sphere 70 is connected to the upper connecting portion 63C of the fixed contact forming piece 63. Are in contact with the side surfaces of the leg portions 64A of the fixed contact forming piece 64, and the fixed contact forming pieces 63 and 64 are short-circuited. As a result, the space between the fixed contact forming pieces 63 and 64 shown in FIG. 8 is closed. On the other hand, the space between the fixed contact forming pieces 61 and 62 shown in FIG. 8 remains open.

  When the space between the fixed contact forming pieces 63 and 64 is closed, the power supply voltage is supplied from the power supply terminal VCC through the fixed contact forming pieces 63 and 64 to the resistor RC1, and the power supply voltage is supplied to the gate of the transistor ETR1 through the resistor RC1. Supplied. However, since the transistor ETR1 is already on, the transistor ETR1 continues to supply the power supply voltage to the light emitting diodes D1 to D6, and the light emitting diodes D1 to D6 continue to light up.

(Light-off operation of light-emitting diode after earthquake stop)
When the earthquake stops, the sphere 70 rolls down the inclined surfaces 60A and 60B due to its own weight, fits into the recess 59A of the mounting table 58, and stops on the mounting surface 59. Thereafter, when the commercial power supply is restored, the light emitting diodes D1 to D6 need not be lit. Therefore, the user presses the reset switch RTSW through the switch opening 42 in order to turn off the light emitting diodes D1 to D6.

  When the reset switch RTSW is pressed and the switch RTSW is closed, the power supply voltage is supplied from the power supply terminal VCC to the gate of the transistor ETR2, and the transistor ETR2 is turned on. When the transistor ETR2 is turned on, the potential of the gate of the transistor ETR1 is forcibly lowered to a low potential. For this reason, the transistor ETR1 changes to the off state, and the current flowing from the emitter to the base of the transistor BTR is cut off. By shutting off the current to the base, the transistor BTR is turned off, and the supply of the power supply voltage from the power supply terminal VCC to the gate of the transistor ETR1 is stopped. As a result, the transistor ETR1 changes to the off state, the power supply voltage from the power supply terminal VCC is not supplied to the light emitting die auto D1 to D6, and the light emitting die auto D1 to D6 is turned off.

(Reduction in charging voltage of capacitor CND for storage)
If the light emitting diodes D1 to D6 continue to be lit without pressing the reset switch RTSW, the charging voltage of the storage capacitor CND continues to decrease. When the charging voltage of the storage capacitor CND does not reach a predetermined value, the reset IC 90 does not output a reset signal from the output terminal RT3. When the reset signal is not output, the potential of the gate of the transistor ETR3 is lowered and the transistor ETR3 is turned off. When the transistor ETR3 is turned off, the power supply voltage from the power supply terminal VCC, that is, the charging voltage of the storage capacitor CND, is supplied to the gate of the transistor ETR4, and the transistor ETR4 is turned on. When the transistor ETR4 changes to the on state, the potential of the gate of the transistor ETR1 is forcibly lowered to a low potential, similarly to the change of the transistor ETR2 to the on state. For this reason, the transistor ETR1 changes to the off state, and the current flowing from the emitter to the base of the transistor BTR is cut off. By shutting off the current to the base, the transistor BTR is turned off, and the supply of the power supply voltage from the power supply terminal VCC to the gate of the transistor ETR1 is stopped. As a result, the transistor ETR1 changes to the off state, the power supply voltage from the power supply terminal VCC is not supplied to the light emitting die auto D1 to D6, and the light emitting die auto D1 to D6 is turned off. When the light emitting diode is turned off, consumption of the charging voltage of the storage capacitor CND is stopped.

(Positional relationship of the sphere 70 in the short circuit state)
FIG. 10 shows a state in which the sphere 70 short-circuits both the fixed contact forming pieces 61 and 62. In FIG. 10, the position CP is the position of the center of the sphere 70 that short-circuits both the fixed contact forming pieces 61 and 62. The position PA1 is a contact position where the inclined surface of the upper connecting portion 61C of the fixed contact forming piece 61 is in contact with the sphere 70 in the short circuit state. The position PA2 is a contact position where the side surface of the leg portion 62A of the fixed contact forming piece 62 contacts the sphere 70 in the short circuit state, and is positioned above the position PA1. The radius R is the radius of the sphere 70. The distance LA1 is a distance from the upper end 60A-1 of the inclined surface 60A to the position PA1 in the horizontal direction that is the horizontal direction. The distance LA2 is a distance from the upper end 60A-1 of the inclined surface 60A to the position PA2 in the horizontal direction that is the horizontal direction. In the present embodiment, the distance LA2 is set larger than the distance LA1. The distance LA2 is set to be larger than the radius R of the sphere 70 and smaller than twice the radius R that is the diameter of the sphere 70. The distance (LA2-LA1) between the position PA1 and the position PA2 is set to be smaller than the radius R of the sphere 70. The center position CP of the sphere 70 in the short circuit state is located at substantially the same position as the position PA2 in the vertical direction which is the vertical direction.

  The positional relationship between the sphere 70 and both the fixed contact forming pieces 63 and 64 is similar to the positional relationship between the sphere 70 and both the fixed contact forming pieces 61 and 62. The position PB1 is a contact position where the inclined surface of the upper connecting portion 63C of the fixed contact forming piece 63 comes into contact with the sphere 70 in the short-circuit state. The position PB2 is a contact position where the side surface of the leg portion 64A of the fixed contact forming piece 64 is in contact with the sphere 70 in the short circuit state, and is located above the position PB1. The distance LB1 is a distance from the upper end 60B-1 of the inclined surface 60B to the position PB1 in the horizontal direction, which is the horizontal direction. The distance LB2 is the distance from the upper end 60B-1 of the inclined surface 60B to the position PB2 in the horizontal direction, which is the horizontal direction. In the present embodiment, the distance LB2 is set larger than the distance LB1. The distance LB2 is set larger than the radius R of the sphere 70 and smaller than the diameter of the sphere 70. The distance (LB2-LB1) between the position PB1 and the position PB2 is set to be smaller than the radius R of the sphere 70. The center position CP of the sphere 70 in the short circuit state is located at substantially the same position as the position PB2 in the vertical direction which is the vertical direction.

[Effect of the first embodiment]
In the first embodiment, since the fixed contact forming pieces 62 and 64 stand vertically from the switch board 52, the sphere 70 contacts each fixed contact forming piece during an earthquake. Thus, the fixed contact forming pieces 61 and 62 or the fixed contact forming pieces 63 and 64 are securely short-circuited. As a result, the earthquake detection device 22 can reliably detect the occurrence of an earthquake. Further, since the mounting table 58 has inclined surfaces 60A and 60B and the upper connecting portions 61C and 63C of the fixed contact forming pieces 61 and 63 are formed to be inclined, the sphere 70 is moved by its own weight after the earthquake is stopped. The inclined surface rolls down and is returned to the mounting surface 59 of the mounting table 58, and rests on the mounting surface 59. As a result, the user does not need to perform the work of returning the sphere 70 to the placement surface 59 in preparation for the next earthquake.

  In the first embodiment, in a state where the sphere 70 short-circuits both the fixed contact forming pieces 61 and 62, the position PA2 is located at substantially the same height as the center position CP of the sphere 70 in the short-circuited state, and the leg portion 62A is Stands above position PA2. As a result, when the spherical body 70 abuts on the leg portion 62A, the sphere 70 does not get over the leg portion 62A and stops without fail, so that both the fixed contact forming pieces 61 and 62 can be short-circuited reliably. Further, the center position CP of the sphere 70 in a short-circuited state is located closer to the placement position of the placement surface 59 than the position PA1 in the left-right direction. As a result, after the sphere 70 comes into contact with the leg 62A and stops, the sphere 70 can be rolled back toward the placement surface 59 and reliably returned.

  In the first embodiment, since the reset switch RTSW is exposed to the outside through the switch opening 42 of the main body cover 31, the user can easily operate the reset switch RTSW. As a result, it is possible to prevent wasteful power supply from the storage capacitor CND to the light emitting diodes D1 to D6 by a simple switch operation after the earthquake has stopped.

  In the first embodiment, the reset IC 90 stops outputting the reset signal when the charging voltage of the storage capacitor CND does not reach a predetermined value, and the transistor ETR1 is forcibly turned off by stopping the output of the reset signal. Change. As a result, it is possible to prevent the power storage capacitor CND from being overdischarged by continuing the power supply from the power storage capacitor CND to the light emitting diodes D1 to D6 after the earthquake has stopped.

  In the first embodiment, an opening 39 into which a transparent plate is fitted is disposed in the main body cover 31, and the front cover 50 and the case main body 51 of the earthquake detection device 22 are molded from a transparent material. As a result, the user can easily confirm the positions of the spheres 70 inside the front cover 50 and the case main body 51 through the opening 39 without performing a complicated operation such as disassembling the sliding door lighting device 1. . Through this confirmation, it is possible to easily find the occurrence of an abnormal state in which the sphere 70 has not returned to the placement surface 59.

  In the first embodiment, the upper left corner of the case main body 51 is brought into contact with the positioning projections 37A and 37B of the main body mounting plate 30, and the lower end of the case main body 51 is brought into contact with the positioning projection 37C of the main body mounting plate 30. By doing so, the earthquake detection device 22 is positioned in the left-right direction and the up-down direction with respect to the main body mounting plate 30. As a result, if the main body mounting plate 30 of the sliding door lighting device 1 is mounted in a horizontal state with respect to the support beam 8 of the sliding door opening / closing device 2, the earthquake detection device 22 can be mounted in a horizontal posture, Earthquake vibration can be detected accurately.

  In 1st Embodiment, in order to irradiate the whole opening / closing area | region of slide door 3A, 3B, the illuminating device 1 for slide doors has a shape long in the left-right direction. Since the earthquake detection device 22 is also built in the sliding door lighting device 1, it has a shape that is long in the left-right direction. As a result, the configuration in which the sphere 70 rolls in the internal space formed by the front cover 50 and the case body 51 is built in a device that is longer in the left-right direction than the configuration in which the sphere moves in the up-down direction. It is an optimal configuration.

It is located above the position PB1. The distance LAC is a distance from the position PA1 to the position PA2 in the horizontal direction that is the horizontal direction. The distance LBC is a distance from the position PB1 to the position PB2 in the horizontal direction that is the horizontal direction. Both distances LAC and LBC are set to be the same. Both distances LAC and LBC are set to be smaller than the radius R of the sphere 70.

  In FIG. 12, the center position CP of the sphere 70 that is in a state of short-circuiting between the mounting contact assembly 158 and the fixed contact forming piece 162 is located at substantially the same position as the position PA2 in the vertical direction that is the vertical direction. . Similarly, the center position CP of the sphere 70 that is in a state of short-circuiting between the mounting contact assembly 158 and the fixed contact forming piece 164 is located at substantially the same position as the position PB2 in the vertical direction that is the vertical direction.

  The pair of fixed contact forming pieces 162 and 164 are formed by bending a conductive material such as a metal material into a U shape. As a conductive material of the fixed contact forming piece, a material obtained by plating steel with tin is conceivable, so that the switch board 152 can be easily soldered. The fixed contact forming piece 162 is attached to the switch board 152 at a position close to the leg portion 161, and has a pair of leg portions 162A and 162B and an upper connecting portion 162C. Both the leg portions 162A and 162B are erected in the vertical direction from the switch board 152, and are formed sufficiently higher than the leg portions 161 of the mounting contact assembly 158.

In a state where vibration such as an earthquake occurs, the sphere 70 rolls on the placement surface 159 and the inclined rolling surfaces 160A and 160B. When the sphere 70 rolls to the position where the fixed contact forming piece 162 is disposed, the ball 70 comes into contact with the position PA1 on the inclined rolling surface 160A and the position PA2 on the side surface of the leg 162A, and the mounting contact assembly 158 The fixed contact forming piece 162 is short-circuited.

[Electrical configuration of lighting device 1 for sliding door]
The electrical configuration of the sliding door lighting device 1 of the second embodiment is the same as the electrical configuration of the first embodiment shown in FIGS. 7 and 8 except for the configuration of the switch board 158. In the switch board 158 of the second embodiment, the leg portion 161 of the mounting contact assembly 158 is directly connected to the terminal ST1 of the connector 65 shown in FIG. 8, and the leg portion 163 is inclined to the mounting contact assembly 158. It is connected to terminal ST1 of connector 65 shown in FIG. 8 via rolling surface 160B, mounting surface 159, inclined rolling surface 160A, and leg portion 161. Fixed contact forming piece 162 and fixed contact forming piece 164 are commonly connected to terminal ST2 of connector 65.

[Operation and Action of Second Embodiment]
(Normal state with no earthquake)
In a normal state, since the sphere 70 is stationary on the mounting surface 159, the mounting contact assembly 158 and the fixed contact forming piece 162 are electrically disconnected without being short-circuited, The mounting contact assembly 158 and the stationary contact forming piece 164 are also electrically disconnected without being short-circuited. As a result, in the normal state, the mounting contact assembly 158 and the fixed contact forming piece 162 and the mounting contact assembly 158 and the fixed contact forming piece 164 are both open. In this open state, as in the first embodiment, the transistor ETR1 is maintained in the off state, and the power supply voltage from the power supply terminal VCC is not supplied to the light emitting dies auto D1 to D6. In a normal state, the power generated by the generator by the opening / closing operation of the sliding door 3A continues to be charged in the storage capacitor CND.

  When the power supply voltage supplied from the storage capacitor CND is equal to or higher than a predetermined value, the reset IC 90 outputs a reset signal from the output terminal RT3, and the transistor ETR3 maintains the on state. While the transistor ETR3 is in the on state, the transistor ETR4 maintains the off state.

  Since the user does not press the reset switch RTSW in the normal state, the reset switch RTSW is kept open, and the supply of the power supply voltage from the power supply terminal VCC to the gate of the transistor ETR2 is stopped by the reset switch RTSW. The As a result, the transistor ETR2 is also kept off.

(Emergency state with earthquake)
When an earthquake occurs, the sphere 70 starts rolling from the mounting surface 159 of the mounting contact assembly 158 along one of the inclined rolling surfaces 160A and 160B, and the mounting surface 159 and both Reciprocating in the left-right direction while rolling on the inclined rolling surfaces 160A, 160B. When the earthquake vibration reaches a strong vibration equal to or higher than a predetermined vibration, the sphere 70 abuts on one of the fixed contact forming pieces 162 and 164. For example, when the sphere 70 rolls to a position PA1 on the inclined rolling surface 160A and comes into contact with the leg portion 162A of the fixed contact forming piece 162, the sphere 70 has an inclined rolling surface 160A as shown in FIG. The upper position PA1 comes into contact with the position PA2 on the side surface of the leg portion 162A of the fixed contact forming piece 162, and the mounting contact assembly 158 and the fixed contact forming piece 162 are short-circuited. As a result, the space between the mounting contact assembly 158 and the fixed contact forming piece 162 is closed, while the space between the mounting contact assembly 158 and the fixed contact forming piece 164 remains open.

  When the space between the mounting contact assembly 158 and the fixed contact forming piece 162 is closed, the transistor ETR1 is turned on, and the power supply voltage from the power supply terminal VCC is supplied to the light emitting die auto D1 to D6. The light emitting diodes D1 to D6 are turned on to illuminate the periphery of the slide doors 3A and 3B. Further, when the space between the mounting contact assembly 158 and the fixed contact forming piece 162 is closed and the transistor ETR1 is once turned on, the transistor BTR is turned on, and the power supply voltage from the power supply terminal VCC is changed to the gate of the transistor ETR1. Continue to supply.

  As shown in FIG. 12, after the spherical body 70 abuts against the fixed contact forming piece 162 and short-circuits between the mounting contact assembly 158 and the fixed contact forming piece 162, the rolling surface is inclined in the right direction by its own weight. When 160A rolls down, the space between the mounting contact assembly 158 and the fixed contact forming piece 162 is opened. Therefore, both the mounting contact assembly 158 and the fixed contact forming piece 162 and between the mounting contact assembly 158 and the fixed contact forming piece 164 are opened, and the power from the power supply terminal VCC is supplied. No voltage is supplied to the gate of transistor ETR1 through resistor RC1. However, since the transistor BTR is in the ON state, the transistor ETR1 supplies the power supply voltage to the light emitting diodes D1 to D6 even after the space between the mounting contact assembly 158 and the fixed contact forming piece 162 is opened. Subsequently, the light emitting diodes D1 to D6 continue to be lit.

  When the sphere 70 rolls to a position PB1 on the inclined rolling surface 160B and comes into contact with the leg portion 164A of the fixed contact forming piece 164, the sphere 70 has a fixed contact with the position PB1 on the inclined rolling surface 160B. Contact is made at the position PB2 on the side surface of the leg portion 164A of the forming piece 164, and the mounting contact assembly 158 and the fixed contact forming piece 164 are short-circuited. As a result, the space between the mounting contact assembly 158 and the fixed contact forming piece 164 is closed, while the space between the mounting contact assembly 158 and the fixed contact forming piece 162 remains open.

  When the space between the mounting contact assembly 158 and the fixed contact forming piece 164 is closed, the power supply voltage is supplied from the power supply terminal VCC to the resistor RC1, and the power supply voltage is supplied to the gate of the transistor ETR1 through the resistor RC1. However, since the transistor ETR1 is already on, the transistor ETR1 continues to supply the power supply voltage to the light emitting diodes D1 to D6, and the light emitting diodes D1 to D6 continue to light up.

  Since the second embodiment performs the same operation as the first embodiment with respect to the operation in the extinguishing operation of the light emitting diode after the earthquake stop and the operation in the decrease in the charging voltage of the storage capacitor CND, the description thereof will be given. Omitted.

[Effects of Second Embodiment]
In the second embodiment, the mounting contact assembly 158 includes the mounting surface 159, the inclined rolling surfaces 160A and 160B, and the inclined rolling surfaces 160A and 160B that constitute switch means together with the fixed contact forming pieces 162 and 164. And contact portions at the upper positions PA1 and PB1, and formed by bending a conductive material. As a result, the configuration of the earthquake detection device 22 can be simplified compared to a configuration in which the mounting table 58 and the fixed contact forming pieces 61 and 63 are separately formed as in the first embodiment.
In the second embodiment, the same effects as those in the first embodiment are exhibited by the same components as those in the first embodiment.
