[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals, and description thereof will not be repeated.

[0010] 1 is a diagram showing a battery exchange device 100 and an electric vehicle 200 according to this embodiment. The battery exchange device 100 is a device for exchanging a battery (used battery) 201 attached to the electric vehicle 200 with a charged battery (new battery) 101. The battery 201 and the battery 101 are examples of the "first battery" and the "second battery" of the present disclosure, respectively.

[0011] (Electric vehicle configuration) As shown in FIG. 3, the electric vehicle 200 has a vehicle body 200a and a cleaning section 200d.

[0012] The vehicle body 200a has a mounting portion 200c on which the batteries 101, 201 can be mounted. As shown in Figure 3, the mounting portion 200c has a shape that is recessed upward from the underside 200b of the vehicle body 200a. The batteries 101, 201 are fastened to the mounting portion 200c by fastening members 205 such as bolts (see Figures 7 and 8).

[0013] The cleaning unit 200d cleans the fastening member 205. As shown in Figures 8 and 9, the cleaning unit 200d has an ejection unit 200e, a supply unit 200f, and a cover 200h.

[0014] As shown in FIG. 9, the spray unit 200e sprays a cleaning fluid (such as air or cleaning liquid) F capable of cleaning the fastening member 205 toward the fastening member 205. The spray unit 200e is movable in the vertical direction between a spraying position (the position shown in FIG. 9) and a storage position (the position shown in FIG. 8). The spraying position is a position where the cleaning fluid F can be sprayed from below toward the fastening member 205. The storage position is a position where the spray unit 200e is stored within the vehicle body 200a. As shown in FIG. 9, an opening 200b1 that allows the spray unit 200e to pass through is provided in the underside 200b of the vehicle body 200a.

[0015] The supply unit 200f supplies the cleaning fluid to the spray unit 200e. The supply unit 200f includes a pump 200g that sends the cleaning fluid toward the spray unit 200e. The pressure of the cleaning fluid generated by driving the pump 200g moves the spray unit 200e from the stored position to the spraying position. When the pump 200g is stopped, the biasing force of a biasing member (not shown) provided in the supply unit 200f returns the spray unit 200e from the spraying position to the stored position.

[0016] The cover 200h has a shape that closes the opening 200b1 formed in the underside 200b of the vehicle body 200a. The cover 200h is fixed to the underside of the ejector part 200e. The cover 200h closes the opening 200b1 when the ejector part 200e is located in the storage position.

[0017] (Configuration of battery exchange device) The battery exchange device 100 includes a battery exchange station 100a, a storage space 100b, and an underfloor area 100c.

[0018] The battery exchange station 100a is a station where the battery 201 is removed from the electric vehicle 200 and the battery 101 is attached to the electric vehicle 200. The battery exchange station 100a is provided with an entrance / exit 102 for the electric vehicle 200 to enter and exit.

[0019] The hangar 100b stores charged batteries 101. The hangar 100b is provided adjacent to the battery exchange station 100a. The hangar 100b is provided with charging equipment 51 that can charge the batteries 201 removed from the electric vehicle 200. The batteries 201 are charged by the charging equipment 51 in the hangar 100b. The batteries 101 charged in the hangar 100b, i.e., the charged batteries 101, are moved to a temporary storage area 40 provided in the underfloor area 100c and then transported to the electric vehicle 200.

[0020] The underfloor area 100c is provided below the battery exchange station 100a and the storage shed 100b. The underfloor area 100c is provided with a battery mounting platform 34, a lifting unit 35, a first transport unit 36, and a second transport unit 37, which will be described later.

[0021] The battery exchange device 100 includes a control device 10 and a drive device 30.

[0022] The control device 10 includes a processor 11, a memory 12, and a communication unit 13. The memory 12 stores programs executed by the processor 11 as well as information used in the programs (for example, maps, mathematical formulas, and various parameters). As will be described in detail later, the processor 11 controls the drive device 30.

[0023] The communication unit 13 includes various communication I / Fs. The processor 11 controls the communication unit 13.

The communication unit 13 may also communicate with a mobile terminal or the like owned by the user of the electric vehicle 200.

[0024] 2, the battery replacement device 100 is provided with a vehicle stopping area 103. When the electric vehicle 200 is stopped in the vehicle stopping area 103 and a user operates a navigation system (not shown) of the electric vehicle 200 to instruct the start of battery replacement work, the communication unit 13 receives an instruction signal to start the battery replacement work from the electric vehicle 200. The processor 11 starts controlling the battery replacement work based on the communication unit 13 receiving the instruction signal. The electric vehicle 200 is stopped in the vehicle stopping area 103 so that the forward / backward direction is the X direction and the left / right direction is the Y direction.

[0025] The drive device 30 includes a wheel stopper 31 (see Figure 2), a shutter 32 (see Figure 2), a battery mounting stand 34 (see Figure 1), a lifting section 35 (see Figure 1), a first conveying section 36 (see Figure 1), and a second conveying section 37 (see Figure 1).

[0026] 2, the vehicle stopping area 103 is provided with four wheel stoppers 31. The wheel stoppers 31 are provided to correspond to the four wheels 202 of the electric vehicle 200, respectively.

[0027] The wheel stopper 31 includes a pressing member 31a and a lateral roller 31b. The pressing member 31a presses the wheel 202 from the outside (side) to move the wheel 202. The pressing member 31a is disposed so as to straddle the lateral roller 31b. In this way, the wheel 202 is positioned by the wheel stopper 31.

[0028] The lateral roller portion 31b is composed of a plurality of rollers whose rotation axes extend along the X direction. The rollers of the lateral roller portion 31b are aligned along the Y direction. When the rollers of the lateral roller portion 31b rotate, the pressing member 31a moves along the Y direction.

[0029] 2, the shutter 32 is provided in the vehicle stopping area 103. The shutter 32 is configured to be able to open and close an opening 32a formed in the floor surface FL of the vehicle stopping area 103. The shutter 32 is switchable between an open state in which the opening 32a is open and a closed state in which the opening 32a is closed.

[0030] The lifting unit 35 is capable of moving up and down through the opening 32a between a position higher than the floor surface FL and a position lower than the floor surface FL. As shown in Fig. 3, the lifting unit 35 is capable of lifting the electric vehicle 200 while holding the electric vehicle 200 from below to a position where the wheels 202 of the electric vehicle 200 are lifted off the floor surface FL. The lifting unit 35 lifts the electric vehicle so that the height H of the underside 200b of the vehicle body 200a from the floor surface FL reaches a predetermined height.

[0031] The lifting section 35 includes a pair of lifting bars 35a spaced apart in a direction (Y direction) perpendicular to the up-down direction. Each of the pair of lifting bars 35a is provided with two protrusions 35b that protrude upward. The electric vehicle 200 is supported from below by the two protrusions 35b on each of the pair of lifting bars 35a (i.e., four protrusions 35b).

[0032] The battery mounting stand 34 is disposed below the battery exchange station 100a, more specifically below the opening 32a. The battery mounting stand 34 is capable of mounting batteries 101, 201 and is movable up and down. As shown in Fig. 4, the battery mounting stand 34 has a base 34e, two positioning pins 34a, four locking / unlocking tools 34b, a roller 34c, and a stopper 34f.

[0033] The base portion 34e is disposed between the pair of lifting bars 35a. The base portion 34e is movable in the up and down direction. The base portion 34e is formed in a flat plate shape. The base portion 34e has an outer shape larger than the outer shape of the batteries 101, 201. The base portion 34e is configured to be movable in the horizontal direction below the electric vehicle 200. Specifically, the base portion 34e is movable in the X direction (X1 direction, X2 direction) and the Y direction (Y1 direction, Y2 direction). The base portion 34e is rotatable so as to change its orientation (angle) within the XY plane. Note that each of the pair of lifting bars 35a may also be movable in the same way as the base portion 34e.

[0034] Each positioning pin 34a is provided on the base portion 34e. Each positioning pin 34a is a portion for positioning the base portion 34e with respect to the vehicle body 200a of the electric vehicle 200. One positioning pin 34a is provided on one end of the base portion 34e in a direction parallel to the vehicle width direction (Y direction). The other positioning pin 34a is provided on the other end of the base portion 34e in a direction parallel to the vehicle width direction (Y direction).

[0035] 5, pin insertion holes 208 into which the positioning pins 34a are inserted are provided on the underside 200b of the vehicle body 200a of the electric vehicle 200. The positioning pins 34a can be inserted into the pin insertion holes 208.

[0036] Each locking / unlocking tool 34b is movable in the vertical direction. Each locking / unlocking tool 34b is movable in the vertical direction relative to the base portion 34e. As shown in Fig. 4, each locking / unlocking tool 34b is disposed inside a pair of positioning pins 34a in the Y direction. Each locking / unlocking tool 34b is disposed outside the base portion 34e in the X direction.

[0037] 5, the battery 201 has a bottom surface 201e, which is provided with tool insertion holes 201f into which the locking / unlocking tools 34b are inserted. A tool insertion hole is also provided in the bottom surface of the battery 101. The locking / unlocking tools 34b can be inserted into the tool insertion hole.

[0038] The roller portion 34c is provided on the base portion 34e. The roller portion 34c is rotatable around a rotation axis extending in the X direction. When the roller portion 34c rotates in one direction, the batteries 101, 201 move relative to the base portion 34e to one side in the Y direction (e.g., the Y1 side), and when the roller portion 34c rotates in the other direction, the batteries 101, 201 move relative to the base portion 34e to the other side in the Y direction.

[0039] The markers 34d are provided at the tip of each positioning pin 34a. The markers 34d are made of light-emitting elements such as LEDs. The markers 34d may have a tapered shape toward the top.

[0040] The stopper 34f is provided on the base portion 34e and will be described later.

[0041] 1 again, the first transport unit 36 ​​transports the batteries 101 stored in the storage 100b toward the battery mounting stand 34. Specifically, a temporary storage area 40 is provided in the underfloor area 100c for temporarily storing the charged batteries 101 stored in the storage 100b, and the first transport unit 36 ​​can transport the batteries 101 from the temporary storage area 40 toward the battery mounting stand 34. Note that the first transport unit 36 ​​may be, for example, a belt conveyor type.

[0042] The second transport unit 37 transports used batteries 201 that have been removed from the electric vehicle 200 and placed on the battery mounting stand 34 from the battery mounting stand 34. Specifically, a storage space 42 for storing batteries 201 is provided in the underfloor area 100c at a position away from the storage shed 100b, and the second transport unit 37 transports the batteries 201 from the battery mounting stand 34 to the storage space 42 along the transport direction (Y2 direction) in which the first transport unit 36 ​​transports the batteries 101 toward the battery mounting stand 34. The first transport unit 36 ​​and the second transport unit 37 are arranged so as to be aligned in the same straight line. The second transport unit 37 may also be, for example, a belt conveyor type.

[0043] The storage space 42 is provided with charging equipment 52 capable of charging the battery 201. The battery 201 stored in the storage space 42 is transported to the storage shed 100b by a transport unit (not shown) after or during charging by the charging equipment 52. The transport unit may be composed of a first transport unit 36 ​​and a second transport unit 37.

[0044] Here, the stopper 34f will be described. The stopper 34f is provided on the base portion 34e at a location downstream of the roller portion 34c in the conveying direction (Y2 direction). The stopper 34f abuts against the battery 101 conveyed from the first conveyor 36 to the base portion 34e in the direction opposite to the conveying direction. The position of the stopper 34f in the direction parallel to the conveying direction (Y direction) is set based on the position of the battery 201 mounted on the electric vehicle 200. The stopper 34f is movable in the vertical direction between a protruding position (position shown in FIG. 4) where it protrudes upward from the base portion 34e so as to abut against the battery 101, 201, and a recessed position where it is recessed within the base portion 34e so as to allow movement of the used battery 201 from the base portion 34e to the second conveyor 37.

[0045] Movement of the stopper 34f between the protruding position and the recessed position is controlled by the processor 11 of the control device 10. The processor 11 positions the stopper 34f in the protruding position when a charged battery 101 is moved from the first transport section 36 to the base section 34e, and positions the stopper 34f in the recessed position when a used battery 201 is moved from the base section 34e to the second transport section 37.

[0046] (Battery replacement method) Next, a battery exchange method using the battery exchange device 100 will be described with reference to the flow chart (sequence diagram) of FIG.

[0047] [Transmission of vehicle information, etc.: Electric vehicles] First, in step S21, the electric vehicle 200 transmits information about the electric vehicle 200 and information about the battery 201 to the communication unit 13 of the battery exchange apparatus 100. For example, an operation to transmit each piece of information described above is performed in a navigation system (not shown) of the electric vehicle 200, whereby each piece of information described above is transmitted to the communication unit 13. The electric vehicle 200 transmits each piece of information described above before entering the battery exchange apparatus 100. Note that each piece of information described above may also be transmitted after the electric vehicle 200 enters the battery exchange apparatus 100.

[0048] [Acquisition of vehicle information, etc.: Battery replacement device] Next, in step S1, the communication unit 13 of the battery exchange device 100 acquires, by communication, the information about the electric vehicle 200 and the information about the battery 201 transmitted from the electric vehicle 200 in step S21. The acquired information is stored in the memory 12 (see FIG. 1).

[0049] The communication unit 13 may also acquire information on the capacity (charge capacity) of the battery 201 and the SOC (State Of Charge) of the battery 201.

[0050] [Sending instruction signals for battery replacement: electric vehicle] Next, in step S22, the electric vehicle 200 parked in the vehicle stopping area 103 transmits to the communication unit 13 an instruction signal to start the battery replacement work.

[0051] [Battery replacement instruction signal received: Battery replacement device] Next, in step S2, the communication unit 13 receives the instruction signal transmitted from the electric vehicle 200 in step S22. After receiving the instruction signal, in step S2, the processor 11 may transmit an instruction message or the like to the user of the electric vehicle 200 via the communication unit 13 to turn off the ignition power supply.

[0052] [Control of wheel clamp: Battery replacement device] Next, in step S3, the processor 11 adjusts the positions of the wheel clamping units 31 (see FIG. 2) based on the information (vehicle information and battery information) acquired in step S1 through the communication unit 13. Note that the processor 11 may control each of the four wheel clamping units 31 independently of one another.

[0053] This adjusts the horizontal position and orientation of the vehicle body 200a, and also adjusts the horizontal position and orientation of the battery 201. As a result, the battery 201 is moved to a predetermined position above the opening 32a.

[0054] [Battery replacement device: Holds the vehicle horizontally] Next, in step S4, processor 11 opens shutter 32 and raises lifting unit 35 while shutter 32 is open. As a result, after passing through opening 32a, lifting unit 35 raises electric vehicle 200 so that height H of underside 200b of vehicle body 200a from floor surface FL reaches a predetermined height (see FIG. 3).

[0055] [Cleaning of fasteners: vehicles] Before step S4 is completed or before step S5 is started, the cleaning unit 200d cleans the fastening member 205. First, the pump 200g of the supply unit 200f is driven. The pressure of the cleaning fluid F generated thereby causes the spraying unit 200e to move from the stored position to the spraying position and spray the cleaning fluid F toward the fastening member 205. This cleans the fastening member 205, thereby removing dirt adhering to the fastening member 205 or its vicinity (such as the tool insertion hole 201f). Note that the cleaning of the fastening member 205 may be performed inside or outside the battery exchange station 100a.

[0056] [Removing the battery after use: Battery replacement device] Next, in step S5, the used battery 201 is removed from the body 200a of the electric vehicle 200. First, the processor 11 raises the battery mounting base 34. As a result, as shown in FIG. 7, the positioning pin 34a is inserted into the pin insertion hole 208 formed in the underside 200b of the body 200a, and the locking / unlocking tool 34b is inserted into the tool insertion hole 201f formed in the bottom surface 201e of the battery 201, so that the base portion 34e abuts against or approaches the bottom surface 201e of the battery 201. As a result, the battery mounting base 34 is positioned relative to the electric vehicle 200 (battery 201). Note that, at this time, the positioning pin 34a is inserted into the pin insertion hole 208 before the locking / unlocking tool 34b is inserted into the tool insertion hole 201f.

[0057] Next, the processor 11 raises the locking / unlocking tool 34b while the locking / unlocking tool 34b is inserted into the tool insertion hole 201f. Then, the processor 11 drives (rotates) the locking / unlocking tool 34b inserted into the tool insertion hole 201f. This unlocks the fastening member 205 in the tool insertion hole 201f. As a result, the battery 201 is removed from the vehicle body 200a and placed on the base part 34e. Note that the timing at which the positioning pin 34a is inserted into the pin insertion hole 208 and the timing at which the locking / unlocking tool 34b is inserted into the tool insertion hole 201f may be the same.

[0058] [Battery exchange device: transporting used batteries to a storage space] Next, in step S6, the battery 201 removed from the vehicle body 200a in step S5 is transported to the storage space 42 (see FIG. 1). First, the processor 11 lowers the battery mounting stand 34 on which the battery 201 is mounted to the height position of the second transport unit 37 (see FIG. 1). Next, the processor 11 lowers the lifting unit 35 to a position lower than the battery mounting stand 34 (for example, the position shown in FIG. 1). As a result, the vehicle body 200a is no longer held by the lifting unit 35, and the electric vehicle 200 is placed on the floor surface FL of the vehicle stopping area 103. At this time, the processor 11 positions the stopper 34f in the buried position. Next, the processor 11 drives the roller unit 34c (see FIG. 4) of the battery mounting stand 34 so that the battery 201 moves on the base unit 34e in the transport direction (direction Y2). As a result, the battery 201 placed on the base portion 34e moves on the base portion 34e toward the second transporter 37 without coming into contact with the stopper 34f, and is transferred from the base portion 34e to the second transporter 37. The battery 201 is transported by the second transporter 37 to the storage space 42 and stored there. The battery 201 may be charged by the charging equipment 52 in the storage space 42. After charging is complete or during charging, the battery 201 is transported to the storage warehouse 100b by the transport unit.

[0059] [Charged batteries are transported to the battery mounting platform: Battery exchange device] Next, in step S7, the processor 11 transports the charged battery 101 stored in the storage 100b to the battery mounting stand 34. Specifically, the processor 11 transports the battery 101 from the storage 100b to the temporary storage area 40 in the underfloor area 100c, and then transports the battery 101 from the temporary storage area 40 to the battery mounting stand 34 along the transport direction (Y2 direction) using the first transport unit 36. At this time, the processor 11 positions the stopper 34f in the protruding position. When the battery 101 moves from the first transport unit 36 ​​to the base unit 34e, the processor 11 drives the roller unit 34c so that the battery 101 moves on the base unit 34e along the transport direction. As a result, the battery 101 abuts against the stopper 34f and stops at a predetermined position on the base unit 34e.

[0060] [Installing a charged battery: Battery exchange device] Next, in step S8, the processor 11 performs control to attach the charged battery 101 to the vehicle body 200a. Specifically, the processor 11 raises the lifting unit 35 so that the height H of the underside 200b of the vehicle body 200a from the floor surface FL of the vehicle stopping area 103 reaches a predetermined height.

[0061] Next, the processor 11 raises the battery mounting base 34. This inserts the positioning pin 34a into the pin insertion hole. In this state, the processor 11 raises the locking / unlocking tool 34b. This inserts the locking / unlocking tool 34b into the tool insertion hole of the battery 101. The processor 11 then drives (rotates) the locking / unlocking tool 34b. This locks the bolts in the tool insertion hole. When it is detected that all the bolts are locked, the vehicle-side connector (not shown) and the connector (not shown) of the battery 101 are locked. As a result, installation of the charged battery 101 into the vehicle body 200a is completed.

[0062] [Retraction of battery platform and lifting section: Battery replacement device] Next, in step S9, the processor 11 lowers the battery mounting stand 34 and the lifting unit 35 and moves them away from the electric vehicle 200. Thereafter, the processor 11 closes the shutter 32 (see FIG. 2).

[0063] [Battery replacement completion notification: Battery replacement device] Next, in step S10, the processor 11 notifies the electric vehicle 200 via the communication unit 13 that the battery replacement work has been completed.

[0064] [Receiving notification of completion of battery replacement work: electric vehicle] Then, in step S23, the electrically powered vehicle 200 receives the notification transmitted from the communication unit 13 of the battery exchange apparatus 100 in step S10. This puts the electrically powered vehicle 200 into a state in which the ignition power can be turned on. Thereafter, the process ends.

[0065] In the above embodiment, an example has been shown in which the position of the drive unit 30 is adjusted based on information relating to each of the electric vehicle 200 and the battery 201, but the present disclosure is not limited to this. The position of the drive unit 30 may also be adjusted based on information relating to either the electric vehicle 200 or the battery 201.

[0066] As described above, the electric vehicle 200 in this embodiment is provided with the cleaning unit 200d that cleans the fastening member 205, so that the locking / unlocking tool 34b for removing the fastening member 205 can be effectively fitted onto the fastening member 205.

[0067] In the above embodiment, the cleaning unit 200d may be provided in the battery exchange station 100a. In this case, the cleaning unit 200d is provided on the floor surface FL of the vehicle stopping area 103, the battery mounting stand 34, or the like.

[0068] In the above embodiment, as shown in FIGS. 10 and 11, the cleaning section 200d may have a slider 200j and a cam lever 200m.

[0069] The slider 200j is provided on the vehicle body 200a. The slider 200j is movable relative to the vehicle body 200a in a direction toward the battery 201 (to the right in FIGS. 10 and 11) and a direction away from the battery 201 (to the left in FIGS. 10 and 11). The slider 200j has a first slider portion j1, a second slider portion j2, a rotation shaft j3, a brush portion j4, and a biasing member j5.

[0070] The first slider portion j1 ​​is disposed inside the vehicle body 200a in a position parallel to the lower surface 200b of the vehicle body 200a.

[0071] The second slider portion j2 is disposed in a position perpendicular to the first slider portion j1.

[0072] The rotation shaft j3 connects the first slider portion j1 ​​and the second slider portion j2. More specifically, the rotation shaft j3 connects the base end of the first slider portion j1 ​​to the lower end of the second slider portion j2 so that the first slider portion j1 ​​can rotate around the rotation shaft j3. The vehicle body 200a is provided with a guide slit (not shown) that guides the rotation shaft j3 along the longitudinal direction of the first slider portion j1 ​​(the left-right direction in FIG. 10), and the rotation shaft j3 is movable along the guide slit.

[0073] The brush portion j4 is provided at the tip of the first slider portion j1. The brush portion j4 is capable of cleaning the fastening member 205. The brush portion j4 has a shape that extends upward from the tip of the first slider portion j1.

[0074] The biasing member j5 connects the vehicle body 200a and the rotation shaft j3 and biases the rotation shaft j3 relative to the vehicle body 200a in a direction that moves the rotation shaft j3 away from the battery. The biasing member j5 may be connected to the second slider portion j2.

[0075] The cam lever 200m drives the brush portion j4. Specifically, the cam lever 200m is pushed by a positioning pin 34g provided on the base portion 34e, thereby pressing the slider 200j. Note that the positioning pin 34a may also constitute the positioning pin 34g. The cam lever 200m has a first lever portion m1, a second lever portion m2, and a rotation shaft m3.

[0076] The first lever portion m1 is disposed inside the vehicle body 200a in a position parallel to the underside 200b of the vehicle body 200a. The first lever portion m1 is a portion that receives pressure from the positioning pin 34g.

[0077] The second lever portion m2 is perpendicular to the first lever portion m1 and is capable of pressing the second slider portion j2.

[0078] The rotation shaft m3 connects the first lever portion m1 and the second lever portion m2 together. The rotation shaft m3 connects the first lever portion m1 and the second lever portion m2 together so that the position of the second lever portion m2 relative to the first lever portion m1 is maintained.

[0079] [Cleaning of fasteners: vehicles] As shown by arrow AR1 in Figure 11, when the positioning pin 34g presses the first lever portion m1 upward, the second lever portion m2 rotates around the rotation axis m3 as shown by arrow AR2. Then, as shown by arrow AR3, the second slider portion j2 is pressed by the second lever portion m2, causing the slider 200j to move toward the battery 201 against the biasing force of the biasing member. During this movement, the fastening member 205 is cleaned by the brush portion j4. In Figure 11, the positioning pin 34g, slider 200j, and cam lever 200m before movement are shown by dashed lines.

[0080] When the second slider portion j2 comes into contact with the side surface of the vehicle body 200a, the first slider portion j1 ​​rotates around the rotation axis j3, as indicated by the arrow AR4. At this time, the first slider portion j1 ​​rotates to a position that is out of the path of movement of the battery 201. This prevents the first slider portion j1 ​​and the brush portion j4 from interfering with the removal of the battery 201 from the vehicle body 200a. In FIG. 11, the first slider portion j1 ​​and the brush portion j4 are indicated by two-dot chain lines just before they rotate around the rotation axis m3.

[0081] Thereafter, when the positioning pin 34g moves down together with the base portion 34e, the slider 200j moves toward the cam lever 200m due to the biasing force of the biasing member j5. At this time, the first slider portion j1 ​​rotates around the rotation axis j3 to return to its initial position (the position shown in FIG. 10), and the cam lever 200m is pressed by the second slider portion j2 to return to its initial position (the position shown in FIG. 10).
