Description

Switchgear

The present invention relates to switching devices; more specifically, it relates to switching devices that control loads based on operations performed by humans and physical quantity detection performed by sensors.

As an example of a conventional technique, for example, a switch device (automatic switch with heat ray sensor) described in Document 1 (Japanese Patent Application Publication No. 2008-108637) can be cited. The conventional technology example described in Document 1 (hereinafter referred to as "the conventional technology example") is set on the power supply path from the AC power source to the lighting load. The conventional example of technology is to control the lighting load (switch on and off) by opening and closing the power supply path. Examples of conventional technologies include: a body that is embedded in a wall surface to create a building surface, an operating handle that is rotatably supported on the front surface of the body by a rotating shaft, a heat ray sensor that detects heat rays, an opening and closing element inserted into the power supply path, And the circuit part that drives the switching element. In addition, the heat ray sensor, the opening/closing element, and the circuit part are housed in the body.

The circuit part has an operation switch that will be turned on (on) when the "operation handle" is pressed. The circuit unit switches the switching element from on to off (off) and from off to on every time the operation switch is turned on. Furthermore, the circuit part switches the switching element from off to on whenever the heat ray sensor detects the presence of a person in the detection area. In the circuit part, whenever the heat ray sensor no longer detects the presence of people in the detection area, it switches the opening and closing element from on to off.

The machine system is formed of a synthetic resin material into a rectangular parallelepiped shape. An operation handle is arranged on the upper part of the front surface of the body. A sensor cover is arranged on the lower part of the front surface of the body (under the operating handle). The sensor cover covers the heat ray sensor exposed to the front surface of the body. The sensor cover is made of a material that can transmit heat rays. In other words, the heat rays emitted by the human body will pass through the sensor cover and be detected by the heat ray sensor.

However, in the above-mentioned conventional technical example, the manual operation handle and the sensor cover are arranged on the front surface of the machine body and arranged side by side along the length direction of the machine body. Therefore, when the machine body is to be miniaturized in consideration of design and the like, once the operation handle is miniaturized, the operability of manual operation may be reduced.

[The problem to be solved by the invention] The object of the present invention is to provide a switch device which can achieve miniaturization while suppressing the decrease in operability. [Technical means to solve the problem]

One aspect of the switch device of the present invention has: an operating part for manual operation; and a detecting part through which a predetermined physical quantity is detected. The switch device also has: a control circuit for controlling the load when the operating part is manually operated and when the physical quantity detected by the detecting part meets a predetermined condition; and the body is formed into a box shape to accommodate The control circuit. The operating part has a plate-shaped operating part main body, which is installed on the machine body and covers the detecting part with the operating part main body from the front of the machine body. The detecting part detects the physical quantity through the transmission part arranged on the main body of the operating part.

Hereinafter, the switch device of the embodiment of the present invention will be described in detail with reference to the drawings. However, the drawings described in the following embodiments are schematic diagrams, and the respective ratios of the size and thickness of each component do not necessarily reflect the actual size ratio. In addition, the configuration described in the following embodiments is only an example of the present invention. The present invention is not limited to the following embodiments, as long as the effects of the present invention can be exerted, various changes can be made in accordance with the design and the like.

First, the circuit configuration of the switching device 1 of the embodiment (hereinafter referred to as "switching device 1") will be described. As shown in FIG. 1, the switch device 1 has a first circuit block 4, a second circuit block 5, and a wiring board 6.

The terminal block 6 includes four terminals (a first terminal 61, a second terminal 62, a third terminal 63, and a fourth terminal 64). The first terminal 61 is electrically connected to the positive electrode (the electrode on the HOT side) of the AC power supply X1 (for example, a single-phase two-wire AC power supply with an effective value of 100V). The second terminal 62 is electrically connected to the negative electrode (the electrode on the COLD side) of the AC power supply X1. The third terminal 63 is electrically connected to the first power supply terminal of the lighting load W1 (for example, an LED lighting fixture). The fourth terminal 64 is electrically connected to the second power terminal of the lighting load W1. In addition, the second terminal 62 and the third terminal 63 are electrically connected via a conductor (for example, a wire).

The first circuit block 4 includes a switching element 41, a drive circuit 42, and a DC power supply circuit 43.

The DC power supply circuit 43 converts the AC voltage supplied from the AC power supply X1 via the first terminal 61 and the second terminal 62 into a DC voltage. The DC power supply circuit 43 preferably has, for example, a power factor improvement circuit (boost chopper circuit) and a step-down carrier circuit, and outputs a DC voltage of about 5-15V. The DC power supply circuit 43 supplies the converted DC voltage (hereinafter referred to as a control voltage) to the drive circuit 42 and the second circuit block 5.

The opening/closing element 41 is provided on a circuit electrically connected to the first terminal 61 and the fourth terminal 64 of the terminal block 6. The switching element 41 is composed of an electromagnetic relay, a semiconductor relay, or a semiconductor switching element. When the opening and closing element 41 is turned on, the first terminal 61 and the fourth terminal 64 are conducted through the circuit. On the other hand, when the opening and closing element 41 is disconnected, the circuit will be cut off, and the first terminal 61 and the fourth terminal 64 will not be conducted. In other words, when the switching element 41 is turned on, the AC power supply X1, the lighting load W1, the wiring board 6, and the switching element 41 form a closed circuit, and the AC power supply X1 supplies AC power to the lighting load W1. On the other hand, when the opening and closing element 41 is off, the AC power supply X1, the lighting load W1, the wiring board 6, and the opening and closing element 41 do not form a closed circuit, and the AC power supply X1 does not supply AC power to the lighting load W1.

The driving circuit 42 is controlled by a control circuit 53 described later to turn on/off the switching element 41.

The second circuit block 5 has a human body detection sensor 51, a button switch 52, a control circuit 53 and an indicator light 54.

The human body detection sensor 51 is a so-called passive infrared motion sensor. The infrared motion sensor has a plurality of pyroelectric elements, and detects the human body that emits infrared rays in response to the change of the infrared rays received by the plurality of pyroelectric elements. That is, the human body detection sensor 51 is configured to output a human body detection signal when there is a human body in the detection area.

The button switch 52 has a mechanical normally open contact, and a button 520 that closes (turns on) the normally open contact when a force is received from the outside (see FIG. 3). To the normally open contact of the button switch 52, a control voltage is applied.

The indicator light 54 has, for example, an LED (light emitting diode) die emitting red light and an LED die emitting green light. The indicator light 54 is controlled by the control circuit 53, and is selectively emitted by red light and green light.

The control circuit 53 is composed of a microcontroller. The control circuit 53 has a plurality of input ports and output ports. The first input port is electrically connected to the human body detection sensor 51; the second input port is electrically connected to the button switch 52. In other words, once the human body detection sensor 51 detects a human body, it will input a high-level signal (human body detection signal) to the first input port. Furthermore, when the button switch 52 is turned off, the input voltage of the second input port will be maintained at a high level (control voltage); but once the button switch 52 is turned on, the input voltage of the second input port will change to Low level. Therefore, when the input voltage of the second input port changes from a high level to a low level, the control circuit 53 determines that there is an operation signal input from the button switch 52.

The first output port of the control circuit 53 is electrically connected to the drive circuit 42. The control circuit 53 outputs a control signal from the first output port. The driving circuit 42 drives the switching element 41 once it receives the control signal from the control circuit 53.

The second output port of the control circuit 53 is electrically connected to the indicator light 54. The control circuit 53 outputs a driving signal from the second output port, and the indicator light 54 is illuminated.

The control operation of the control circuit 53 will be described in further detail. The control circuit 53 outputs the control signal from the first output port when the operation signal is input to the second input port under the condition that the opening and closing element 41 is off (the lighting load W1 is off), and the drive circuit 42 Turn on the opening and closing element 41. Furthermore, when the lighting load W1 is turned off, the control circuit 53 outputs a control signal from the first output port once a human body detection signal is input from the human body detection sensor 51 to the first input port to drive The circuit 42 turns on the switching element 41. By turning on the switching element 41, the lighting load W1 lights up.

By causing the control circuit 53 to emit green light from the indicator light 54 when the lighting load W1 is off, the position of the switch device 1 can be easily recognized even in dim surroundings. Furthermore, by causing the control circuit 53 to emit red light from the indicator light 54 when the lighting load W1 is turned on, it will indicate that the lighting load W1 is turning on.

On the other hand, when the lighting load W1 is lighting, the control circuit 53 outputs a control signal from the first output port once an operation signal is input to the second input port, and the driving circuit 42 turns off the switching element 41 . Furthermore, when the lighting load W1 is lighting up, the control circuit 53 will output the control signal from the first output port once there is no more human detection signal input from the human detection sensor 51 to the first input port. The driving circuit 42 turns off the switching element 41. By turning off the opening and closing element 41, the lighting load W1 is turned off.

Here, the control circuit 53 can also start the timer built in the microcontroller when the input of the human body detection signal stops when the lighting load W1 lights up, and wait until the timer time reaches the predetermined time. During the delay time, the control signal is output again. However, it is preferable that the control circuit 53 restarts the timer to reset the timer time as long as the human body detection signal is input to the first input port again before the timer time reaches the delay time. Furthermore, it is preferable to make the control circuit 53 stop the timer and output the control signal to turn off the opening and closing element 41 once an operation signal is input to the second input port before the timer time reaches the delay time.

In addition, the control circuit 53 may be selected and executed between the first control operation and the second control operation. Preferably, when the control circuit 53 inputs the operation signal multiple times (for example, twice) in a short time (for example, 500 milliseconds), it alternately selects between the first control action and the second control action.

When the control circuit 53 executes the first control action, it will switch the lighting load W1 on/off in response to the human body detection signal from the human body detection sensor 51. Furthermore, when the control circuit 53 performs the second control action, regardless of the presence or absence of the human body detection signal of the human body detection sensor 51, it will switch the lighting load W1 in response to the input of the operation signal from the button switch 52 / Lights out.

The upright wall 214 is tied to the front surface of the cover main body 210 and protrudes forward along the edge of the opening 215. Furthermore, there is an operating piece 2141 which protrudes upward from the bottom surface of the opening 215 facing the vertical wall 214 (refer to FIG. 3). The operation piece 2141 is formed in a T shape when viewed from the front and rear direction. The operating piece 2141 is supported by the vertical wall 214 to be able to bend in the front-to-rear direction with the joint part with the vertical wall 214 as a fulcrum. In addition, on the front surface of the operation piece 2141, a cylindrical rib 2142 is integrally formed (see FIG. 4).

The pair of vertical pieces 211 protrude forward from the left and right ends of the cover main body 210, respectively (refer to FIG. 3).

The operating body 33 is composed of a coil spring. One end (front end) of the operating body 33 in the longitudinal direction (the axial direction of the coil spring) is held by the holding portion 3020 of the handle body 30 (refer to FIG. 4).

The lens unit 32 has a base 320 and a plurality of lenses 321. The base portion 320 is formed in a rectangular plate shape. However, at the peripheral edge of the rear surface of the base portion 320, a peripheral wall 322 protruding backward is integrally formed (see FIG. 4).

On the rear surface of the base part 320, a plurality of lenses (10 in the example shown) are integrally formed with lenses 321 (refer to FIGS. 4 to 7). However, in the following description, the ten lenses 321 may be referred to as the first to fifth lenses 321A to 321E and the sixth to tenth lenses 321F to 321J.

The first to fifth lenses 321A to 321E are arranged in a row in the left-right direction. The third lens 321C in the center is a part of the Fresnel lens (see FIG. 7). The first lens 321A, the second lens 321B, the fourth lens 321D, and the fifth lens 321E are elliptical grooves with different major and minor diameters, arranged in a stack to form a simulated Fresnel lens . The first to fifth lenses 321A to 321E are configured to condense the infrared light incident from the front to a focal point behind the third lens 321C.

The sixth to tenth lenses 321F to 321J are located below the first to fifth lenses 321A to 321E, and are arranged in a row in the left-right direction. The eighth lens 321H in the center is a part of the Fresnel lens (see FIG. 7). The sixth lens 321F, the seventh lens 321G, the ninth lens 321I, and the tenth lens 321J are a plurality of semi-elliptical or quarter-elliptic grooves with different major and minor diameters, arranged in a stack , To form a simulated Fresnel lens. The sixth to tenth lenses 321F to 321J are configured to condense the infrared light incident from the front to the focal point of the third lens 321C.

In addition, the base portion 320, the ten lenses 321 and the peripheral wall 322 are preferably formed of a synthetic resin material whose infrared transmittance and total light transmittance are tens of% (for example, 80%) or more. However, if the infrared transmittance of the synthetic resin material forming the lens 321 is more than tens of% (for example, 80%), the infrared transmittance of the synthetic resin material forming the base portion 320 may be several% or less.

In the lens unit 32, a plurality of lenses 321 are inserted into the window portion 303 and attached to the front surface of the handle body 30 (refer to FIGS. 3 to 6). In addition, on the rear surface of the upper and lower ends of the peripheral wall 322, there are respectively provided cylindrical protrusions 323 (FIG. 7 ). These protrusions 323 are engaged with recesses 3003 (refer to FIG. 3) provided on the front surfaces of one pair of lateral walls 3002 of the frame portion 300. In this way, the lens unit 32 is positioned on the frame portion 300 of the handle body 30 by engaging each of the plurality of protrusions 323 into the plurality of recesses 3003 one by one.

The first to fifth lenses 321A to 321E are above the reinforcing bar 304 and inserted into the window 303; the sixth to tenth lenses 321F to 321J are below the reinforcing bar 304 and inserted into the window 303 (see FIG. 8). The reinforcing bar 304 is in contact with the area between the first to fifth lenses 321A to 321E and the sixth to tenth lenses 321F to 321J on the rear surface of the base portion 320 (see FIG. 4). In other words, when the operating handle 3 is pressed by a human hand or finger, the reinforcing bar 304 can be used to suppress the deformation (bending) of the lens 321.

The handle cover 31 is formed in a rectangular plate shape (refer to FIG. 3). The handle cover 31 is attached to the front surface of the lens unit 32 (refer to FIG. 4). The handle cover 31 prevents dirt from adhering to the front surface of the lens unit 32 and the front surface of the lens unit 32 from being damaged. In addition, the handle cover 31 is preferably made of a synthetic resin material (for example, a polyolefin-based Resin material) to form.

The operating handle 3 is fitted to the body 2 to cover the front surface of the body 2 by engaging the pair of shafts 306 of the handle body 30 into the pair of bearing holes 2110 of the cover 21 one by one (refer to FIGS. 4 to 6 ). The operating handle 3 is rotatable with a pair of shafts 306 as fulcrums. However, the rib 2142 of the cover 21 is locked into the other end (rear end) of the operating body 33 in the longitudinal direction (the axial direction of the coil spring) (refer to FIG. 4). Therefore, when the handle 3 is operated, due to the elastic force of the operating body 33, the lower part of the handle body 30 is pushed away from the front surface of the body 2, while the upper part of the handle body 30 (the upper transverse wall 3002) is stationary at The position (reference position) of the horizontal piece 212 abutting on the upper side of the cover 21 (refer to FIG. 4).

When the lower part of the operating handle 3 is pushed back, the operating handle 3 is rotated (forward rotation) with the lower part of the handle body 30 approaching the front surface of the body 2. As the operating handle 3 rotates, the operating piece 2141 of the cover 21 will bear the elastic force of the operating body 33 and bend backward. By bending the operating piece 2141 backward, the button 520 of the button switch 52 is pressed by the operating piece 2141, and the button switch 52 is turned on. Then, when the lower part of the operating handle 3 is no longer pressed, the elastic force of the operating body 33 causes the operating handle 3 to rotate (reverse) and return to the reference position, and the operating piece 2141 will also return to its original state , Thereby the button switch 52 will be turned off.

Furthermore, when viewed from the front, there is a human body detection sensor 51 inside the window 303 of the handle body 30 of the operating handle 3 (refer to FIG. 8). Therefore, the human body detection sensor 51 can receive the infrared rays emitted by the human body through the handle cover 31 and the window portion 303 of the handle body 30 to detect the human body.

Therefore, the switch device 1 hides the human body detection sensor 51 behind the operation handle 3. Compared with the case where the operation handle 3 and the human body detection sensor 51 are arranged in the up and down or left and right directions, there is no need to change The size of the operating handle 3 achieves miniaturization. As a result, the switch device 1 can achieve downsizing while suppressing the decrease in operability (of the operating handle 3).

Here, when the operating handle 3 is stationary at the reference position, the third lens 321C and the window portion 511 of the housing 510 of the human body detection sensor 51 overlap in the left-right direction and the up-down direction (refer to FIG. 8). Furthermore, when the operating handle 3 is stationary at the reference position, the focal point of the third lens 321C is almost the same as the light-receiving surface of the human body detection sensor 51 (the front surface of the window plate 512) in the front and rear direction (refer to the figure). 4). Therefore, the infrared rays emitted by the human body existing in the detection area can be condensed (converged) on the window portion 511 of the human body detection sensor 51 by the plurality of lenses 321. As a result, the switch device 1 can achieve the expansion of the detection area of the human body detection sensor 51.

Furthermore, in the switch device 1, by shielding unnecessary infrared rays with the first front wall 301 and the second front wall 302 of the handle body 30, the human body detection sensor 51 can be prevented from erroneous detection. Especially in the switch device 1, the light-receiving surface (window 511) of the human body detection sensor 51 is arranged above the center position (the position of the reinforcing bar 304) in the vertical direction of the window 303 of the handle body 30处(Refer to Figure 8). Therefore, in the switch device 1, the infrared rays of the illumination light included in the luminaire are not easily incident on the light-receiving surface of the human detection sensor 51, and the human detection sensor 51 can be further prevented from erroneous detection.

Furthermore, in the switch device 1, a detection area is formed by a plurality of detection ranges corresponding to "each of the plurality of lenses 321" one to one, and the detection area can be detected by the human body detection sensor 51 Measure the subtle dynamics of the human body. As a result, the switch device 1 can reduce the possibility that people (human bodies) staying in the detection area will not be detected.

Here, since the total light transmittance of the synthetic resin material forming the handle cover 31 is tens of% or less, it is difficult to see the human body detection sensor 51 through the operating handle 3. As a result, the switch device 1 can suppress the deterioration of the appearance quality caused by seeing the human body detection sensor 51 through the operating handle 3.

So far, the switch device 1 is configured to be inserted into the embedded hole 80 (see FIG. 9) provided in the construction material (for example, the wall material 8) by using the mounting frame 7. The mounting frame 7 is made of a synthetic resin material, and is formed into a rectangular frame shape having a window 70 in the center. The mounting frame 7 has a pair of side pieces 71 facing each other across the window 70. Each of the pair of side pieces 71 is provided with a mounting hole 72 for a plurality of (four) mounting hooks 2120 of the body 2 to be inserted one by one.

In this way, by engaging each of the four mounting claws 2120 into the four mounting holes 72 one by one, the switch device 1 will be mounted on the mounting frame 7 with the body 2 inserted through the window 70 (see FIG. 9 ). Then, by fixing (screw-fixing) the mounting frame 7 to the surface of the wall material 8 in a state where a part of the body 2 is engaged with the embedded hole 80, the switch device 1 is embedded in the construction surface (wall surface) and arranged.

Furthermore, in the switch device 1, the human body detection sensor 51 is not limited to a passive infrared motion sensor. For example, the human body detection sensor 51 does not matter even if it is an active radio wave sensor using millimeter waves.

Next, several modified examples of the switch device 1 will be described with reference to the drawings. However, the switch device 1 of the modified example described below has the same basic structure as the switch device 1 of the above-mentioned embodiment. Therefore, the components common to the switch device 1 of the embodiment are marked with the same reference numerals, and illustration and description are omitted.

First, the switch device 1 of Modification 1 will be described. The switch device 1 of Modification Example 1, as shown in FIG. 10, has two detection parts, a human body detection sensor 51 and a brightness sensor 55.

The brightness sensor 55 converts visible light into electricity (for example, electric current) by using a light receiving element such as a photodiode or a photoelectric crystal to detect the amount of light received by the light receiving element (brightness). The output (output current) of the brightness sensor 55 is converted into a voltage (detection voltage) by a current-voltage converter (not shown), and then input to the input port (the third input port) of the control circuit 53.

The control circuit 53 compares the detection voltage input to the third input port with a predetermined threshold value. When the detection voltage is above the threshold, even if a human body detection signal is input to the first input port, the control circuit 53 will not perform a control action. When the detection voltage does not reach the critical value, once a human body detection signal is input to the first input port, the control circuit 53 will perform a control action. In other words, the control circuit 53 will determine that it is not necessary to turn on the lighting load W1 when the detection voltage exceeds the threshold value, and ignore the input of the human body detection signal and do not perform control actions. On the other hand, when the detection voltage does not reach the critical value, once a human body detection signal is input, the control circuit 53 switches the lighting load W1 from the off state to the on state. However, the switch device 1 of Modification 1 may not include the human body detection sensor 51 but only the brightness sensor 55. In addition, the brightness sensor 55 is preferably embedded on the surface 500 of the second circuit board 50 of the second circuit block 5.

As described above, in the switch device 1 of Modification 1, when the brightness detected by the brightness sensor 55 does not require the illumination of the lighting load W1, it is possible to prevent the lighting load W1 from turning on unnecessarily. Achieve energy saving.

Next, the switch device 1 of Modification 2 will be described. In the switch device 1 of Modification 2, the operating handle 3 can be rotated between two positions of an off position (refer to FIG. 11A) and an on position (refer to FIG. 11B). The operating handle 3, if manually operated in the off position, will rotate to the on position; and if manually operated in the on position, it will rotate to the off position.

Between the operating handle 3 and the front surface of the body 2, two reversing springs 10 (only one in the figure) and two reversing plates 11 (only one in the figure) are arranged (refer to Figures 11A and 11B). Each inversion plate 11 is received in a V-shaped groove 205 provided in the body 2. Each reversing spring 10 is composed of a coil spring. One end (front end) of each reversing spring 10 in the axial direction is fixed to the handle body 30. The other end (rear end) of each reversing spring 10 in the axial direction is hooked to the front end of the reversing plate 11. With the elastic force of each reversing spring 10, the rear end of each reversing plate 11 is pushed against the bottom 206 of the groove 205. In addition, each reversing plate 11 is able to rotate in the up and down direction by using the rear end against the bottom 206 as a fulcrum.

In this way, when the operating handle 3 is in the off position, by making the upper part of the frame 300 of the handle body 30 (the upper transverse wall 3002) abut the front surface of the body 2, the operating handle 3 will be stationary in the broken position. Open position (refer to Figure 11A). Once the operating handle 3 in the off position is pressed, it will rotate the operating handle 3 while compressing the reversing spring 10. Then, as the operating handle 3 rotates, the reversing plate 11 will also rotate, and by making the lower part of the frame 300 of the handle body 30 (the lower transverse wall 3002) abut the front surface of the body 2, The operating handle 3 will be at rest in the on position (refer to Figure 11B).

As described above, in the switch device 1 of Modification 2, when the operating handle 3 is in the on position, the control circuit 53 can ignore the human body detection signal of the human body detection sensor 51 and keep the lighting load W1 in the lighted state . On the other hand, when the operating handle 3 is in the off position, in the switch device 1 of Modification 2, the control circuit 53 can turn on or turn off the lighting load W1 in response to the human body detection signal of the human body detection sensor 51.

Finally, the switch device 1 of Modification 3 will be described. The switch device 1 of the modification 3 is configured such that the operating handle 3 moves in parallel in the front-rear direction with respect to the front surface of the body 2.

Between the upper and lower ends of the operating handle 3 and the front surface of the body 2, at least one return spring 12 is arranged (refer to FIG. 12). The return spring 12 is composed of a coil spring. One end (front end) of the return spring 12 in the axial direction is fixed to the handle body 30. The other axial end (rear end) of the return spring 12 is fixed to the front surface of the body 2. In addition, the bearing hole 2110 of the cover 21 is formed in an elliptical shape whose front and rear direction is the longitudinal direction.

The operating handle 3 is pushed in a direction away from the front surface of the body 2 (forward) by the elastic force of the return spring 12, and rests at a position (reference position) where the shaft 306 abuts the front end of the bearing hole 2110 (refer to FIG. 12). Once the operating handle 3 is pressed, the operating handle 3 is moved backward while compressing the return spring 12, and the button switch 52 is turned on via the operating body 33 and the operating piece 2141 (neither shown). Then, when the operating handle 3 is no longer pressed, the operating handle 3 will return to the reference position by the elastic force of the return spring 12.

As described above, in the switch device 1 of Modification 3, the operation handle 3 can be operated as a button. In addition, the operating handle 3 may also be configured as a sliding operation parallel to the front surface of the body 2. Alternatively, the operating handle 3 may be configured to be rotated around an axis perpendicular to the front surface of the body 2. Furthermore, a touch switch may also be provided on the surface of the operating handle 3, and by performing a touch operation on the touch switch, the control circuit 53 turns on/off the opening and closing element 41. Moreover, in the case of miniaturization of the human body detection sensor, the human body detection sensor can also be considered to be built into the operation handle 3, but the human body detection sensor 51 exemplified in the embodiment cannot be built into the operation handle 3.
