When the first door 131 is in the open state and the worker releases the handle body 262, the door-side engaging portion 242 is in a position raised by the urging force of the spring 244, but the door-side engaging portion is engaged. The joint portion 242 is located at a position away from the body side engaging portion 241 and is in a state not related to the lock of the first door 131. When the first door 131 is slid in the opposite direction to the previous direction in order to close the first door 131 from this state, the door side engaging portion 242 is engaged on the body side immediately before the first door 131 is closed. Although it comes into contact with the joint portion 241 but the inclined surface 242B of the door side engaging portion 242 hits the inclined surface 241B of the body side engaging portion 241, the door side engaging portion 242 resists the urging force of the spring 244. Immersed, the first door 131 is securely closed. The opening / closing of the first door 131 is detected by the first door opening / closing detection mechanism 231. When a lock signal is sent from the control box 3 to the first electric actuator 211 with the first door 131 closed, the arm 21B of the first electric actuator 211 moves in the direction opposite to the above, that is, in the clockwise direction. The slider 271 descends. The pin 272 that descends together with the slider 271 rotates the lock cam 274 in the reverse direction via the limiter spring 273 to engage with the locking recess 264B (see FIG. 3).

When the portable operating device 4 is erroneously operated in the open state of the first door 131 (see FIG. 7B) and a locking signal is sent to the first electric actuator 211, FIG. 8 (A). ), The arm 21B rotates clockwise, the slider 271 descends, and the lock cam 274 abuts on the engaging portion 264. As the slider 271 descends, the pin 272 provided on the slider 271 also descends. At this time, since the lock cam 274 is in contact with the engaging portion 264, the slider 271 descends against the urging force of the limiter spring 273, and damage to the lock cam 274 and the engaging portion 264 is prevented. To.
On the other hand, when an unlocking signal is sent to the first electric actuator 211 with the first door 131 closed, the slider 271 rises as shown in FIG. 8B, but the lock cam 274 locks. There may be an inconvenience that the recess 264B remains caught. Even if such an inconvenience occurs, the pin 272 provided on the slider 271 rises against the urging force of the limiter spring 273, and the lock cam 274 and the engaging portion 264 are prevented from being damaged.

Next, a method for unlocking by a worker with a key in hand will be described with reference to FIG. 9A.
As shown in FIG. 9A, when the cylinder 281 of the cylinder lock 28 is rotated in one direction (counterclockwise) by the key, the engaging plate portion 282 rotates integrally with the cylinder 281. Then, the engaging pin 283 fixed to the engaging plate portion 282 hits the upper engaging surface 271B of the two engaging surfaces 271B and pushes up the slider 271, and the lock cam 274 rotates to rotate the engaging portion 264. Separate from the locking recess 264B. This allows the handle body 262 to rotate. At this time, since the first electric actuator 211 is not energized, there is almost no resistance of the drive unit of the first electric actuator 211 as the slider 271 rises, and the slider 271 rises smoothly.
A method of locking by a worker with a key in hand will be described with reference to FIG. 9 (B).
As shown in FIG. 9B, when the cylinder 281 of the cylinder lock 28 is rotated in the other direction (clockwise) by the key, the engaging plate portion 282 rotates integrally with the cylinder 281 and the engaging pin 283 is rotated. Pushes down the lower engaging surface 271B of the two engaging surfaces 271B of the slider 271. The pin 272 provided at the lower part of the slider 271 descends together with the slider 271, and the lock cam 274 rotates clockwise via the limiter spring 273 to engage with the locking recess 264B of the engaging portion 264. This prevents the handle body 262 from rotating.

[Block diagram of lock system]
A block diagram of the lock system of the first embodiment is shown in FIG.
In FIG. 10, the information processing unit 300 of the control box 3 includes a control unit 35, an input unit 301, an output unit 302, a storage unit 303, a determination unit 304, a fully open operation circuit unit 305, and a fully closed operation circuit unit 306. Has been done.
The input unit 301 inputs signals from the antenna 61, the first to sixth door open / close detection mechanisms 231 to 236, and the ignition on detection mechanism 62, and sends these signals to the control unit 35. The control unit 35 causes the storage unit 303 and the determination unit 304 to execute a predetermined process depending on the content of the signal. In FIG. 10, only the first and sixth electric actuators, the door opening / closing mechanism, and the switching mechanism are shown, and the second to fifth ones are omitted.

The storage unit 303 stores the ID information of the specific portable operation device 4. That is, when the unlock button 41 of the portable operation device 4 is pressed while the registration button 34 is pressed, the ID information of the portable operation device 4 is registered, and when the registration button 34 is pressed for a long time, it is registered. The registration of ID information is canceled. The registration of the ID information of the portable operation device 4 may be performed by pressing the lock button 42 instead of the unlock button 41.
The determination unit 304 determines whether the signal sent from the portable operation device 4 is that of the portable operation device 4 registered in advance, and if the signal from the portable operation device 4 is registered, the determination unit 304 is a portable type. The operation signal received by the input unit 301 from the operation device 4 is allowed to be sent to the control unit 35, and if it is not registered, it is prevented from being sent to the control unit 35.

The control unit 35 receives a signal from the portable operating device 4 when at least one of the first to sixth switching mechanisms 311 to 316 is set to the on position, and receives a signal from the first to the on position. The first to sixth electric actuators 211 to 216 corresponding to the sixth switching mechanism 311 to 316 are operated. That is, the control unit 35 presses the unlock button 41 in a state where a predetermined one of the first to sixth switching mechanisms 311 to 316, for example, the first switching mechanism 311 is switched to the on position in advance. When the operation signal transmitted is received, a signal for unlocking operation is sent to the first electric actuator 211 through the output unit 302. On the other hand, when the lock button 42 is pressed and the transmitted operation signal is received, a signal for locking operation is sent to the first electric actuator 211 through the output unit 302. The determination unit 304 determines the difference between the operation signal transmitted by pressing the unlock button 41 and the operation signal transmitted by pressing the lock button 42.

In the first embodiment, when the fully open operation button 32 of the control box 3 is pressed, the signal is sent to the fully open operation circuit unit 305, and the fully open operation circuit unit 305 is referred to from the first to the sixth via the control unit 35. All of the electric actuators 211 to 216 are unlocked.
When the fully closed operation button 33 is pressed, the signal is sent to the fully closed operation circuit unit 306, and the fully closed operation circuit unit 306 sends all of the first to sixth electric actuators 211 to 216 via the control unit 35. Is locked.
The signal from the ignition on detection mechanism 62 is sent to the control unit 35 via the input unit 301.

The information processing unit 400 of the portable operation device 4 generates an operation signal generation unit 45 that generates an operation signal for operating the first to sixth electric actuators 211 to 216, and an operation signal generated by the operation signal generation unit 45. It has an operation signal transmitting unit 46 to be sent to the control box 3.
The operation signal transmission unit 46 transmits an operation signal for unlocking operation to the information processing unit 300 of the control box 3 when the unlock button 41 is pressed, and when the lock button 42 is pressed, the information processing unit 46 transmits an operation signal for the unlock operation. The operation signal of the locking operation is transmitted to 300.
The operation signal generation unit 45 turns on the LED of the lighting unit 43 when the unlock button 41 or the lock button 42 is pressed. The operation signal generation unit 45 turns on the blue LED when the capacity of the battery 44 is larger than the predetermined value, and turns on the red LED when the capacity is equal to or less than the predetermined value in order to prompt the replacement of the battery 44.

Next, the operation of the lock system of the first embodiment will be described with reference to the flowcharts of FIGS. 11 to 17.
[Delivery base station]
The loading operation of the bottled soft drink at the delivery base station will be described with reference to the flowcharts of FIGS. 11 to 13.
In order to load the bottled soft drink into the truck bed 10, the worker opens some of the first to sixth doors 131 to 136, or opens all the doors. When loading luggage at a base station, the engine of truck 1 is usually turned off.

(Procedure to open and close some doors)
Here, the first door 131 and the second door 132 are exemplified as a part of the doors that need to be opened. The procedure for opening and closing the other doors is the same as the procedure for opening and closing the first door 131 and the second door 132.
When the first door 131 and the second door 132 are opened to load the bottled soft drink into the truck bed 10, the worker in the driver's seat 11 uses the first door 131 and the second door of the control box 3. The first switching mechanism 311 corresponding to 132 and the second switching mechanism 312 are switched to the on position, and the third to sixth switching mechanisms 313 to correspond to the third to sixth doors 133 to 136 that do not need to be opened. Keep 316 in the off position.
Then, the worker descends from the driver's seat 11, moves to the front of the first door 131 and the second door 132, and presses the unlock button 41 of the portable operation device (remote control) 4.
As shown in FIG. 11, when the unlock button 41 is pressed, the remote control operation is received by the control unit 35 via the input unit 301 of the control box 3 (S101). That is, when the unlock button 41 is pressed, the operation signal transmitted from the operation signal transmission unit 46 is sent to the input unit 301 of the control box 3.
The operation signal input to the input unit 301 is sent to the determination unit 304 via the control unit 35. The determination unit 304 performs ID collation based on the ID information whether or not the transmitted operation signal matches the ID information of the portable operation device 4 registered in advance in the storage unit 303 (S102).

As a result of the ID collation, when the ID information of the operation signal sent from the portable operation device 4 matches the registered one (Yes), the operation signal sent from the operation signal transmitting unit 46 is the unlock button 41. The control unit 35 determines the operation request of whether the lock button 42 is pressed or the lock button 42 is pressed (S103). As a result of ID collation, if they do not match (No), the flow ends.
When the operation request in step S103 is "unlocking", the opening / closing of the first door is checked according to the setting condition (S104A).
In step S105A, the control unit 35 determines whether or not the first door 131 is in the closed state based on the detection signal output from the first door open / close detection mechanism 231. If the first door 131 is in the closed state (Yes), it is determined whether the first switching mechanism 311 is in the on position or the off position (S106A). If the first switching mechanism 311 is in the on position, the control unit 35 sends an operation signal to the first electric actuator 211 to control unlocking of the first electric actuator 211 (S107A).

On the other hand, in step S105A, if it is determined that the first door 131 is not closed (No) based on the detection signal from the first door open / close detection mechanism 231 (No), that is, it is determined that the door is open, the control unit 35 will perform the control unit 35. , The door opening lamp 63 is turned on (S108A), and the first electric actuator 211 is not unlocked and controlled.
After the control of the first electric actuator 211 is completed, the opening / closing of the next door is checked (S109A). That is, the opening / closing of the second door 132 is checked (S105A), and thereafter, the same procedure as that for the first door 131 is carried out.
Subsequently, the opening / closing of the third door 133 is checked according to the setting conditions (S104A). If it is determined by step S105A that the third door 133 is in the closed state, it is determined whether the third electric actuator 213 is in the on position or the off position (S106A).
Since the third door 133 is a door that is not planned to be opened, the third switching mechanism 313 is set to the off position. Therefore, the third electric actuator 213 is not controlled to be unlocked. For the fourth to sixth doors 134 to 136, the same procedure as that of the third door 133 is carried out.

The worker opens the first door 131 and the second door 132, and loads the bottled soft drink into the truck bed 10. When the loading operation of the bottled soft drink is completed, the first door 131 and the second door 132 are closed, and the lock button 42 of the portable operation device 4 is pressed.
When the lock button 42 is pressed, the remote control operation is received (S101), and then the ID is collated (S102). As a result of the ID collation, when the ID information of the operation signal sent from the portable operation device 4 matches the registered one (Yes), the signal output from the portable operation device 4 is "unlocked". The control unit 35 determines whether the operation request is "locking" or "locking" (S103), and when the operation request is "locking", the procedure of steps S104B to S109B, which is the same procedure as steps S104A to S109A, is followed. , The first electric actuator 211 and the second electric actuator 212 are locked and controlled.

(Procedure to open and close all doors)
Workers may open and close all doors to load bottled soft drinks. In this case, the worker opens and closes the door according to the flowchart shown in FIG.

The worker presses the fully open operation button 32 as an operation of the fully open fully closed setting means 30A in order to open all the doors. When the fully open operation button 32 is pressed, the control unit 35 determines whether the pressed button is the fully open operation button 32 or the fully closed operation button 33 (S202).
If the pressed button is the fully open operation button 32, the opening and closing of the first to sixth doors is checked according to the setting conditions (S203A).
The control unit 35 determines whether or not the first door 131 is in the closed state based on the detection signal output from the first door open / close detection mechanism 231 (S204A). If the first door 131 is in the closed state (Yes), an operation signal is sent from the control unit 35 to the first electric actuator 211, and the first electric actuator 211 is controlled to be unlocked (S205A). When the first door 131 is in the opened state, the control unit 35 turns on the door opening lamp 63 (S206A) and does not perform the overlapping unlock control of the first electric actuator 211.
After the control of the first electric actuator 211 is completed, the opening / closing of the next door is checked (S207A). That is, the closed state and the open state of the second door 132 are checked (S204A), and thereafter, the same procedure as that for the first door 131 is carried out.

With the first to sixth electric actuators 211 to 216 unlocked, the worker opens all the first to sixth doors 131 to 136 and loads the bottled soft drink.
When the loading work of the bottled soft drink is completed, the worker closes all the first to sixth doors 131 to 136, gets into the driver's seat 11 and operates the fully open and fully closed setting means 30A (S201). .. The worker presses the fully closed operation button 33 of the control box 3 to lock all the doors. It is determined whether the pressed button is the fully open operation button 32 or the fully closed operation button 33 (S202), and if the pressed button is the fully closed operation button 33, opening / closing of the first to sixth doors is a setting condition. Check according to (S203B).
It is determined whether or not the first door 131 is in the closed state based on the signal output from the first door open / close detection mechanism 231 (S204B), and if the first door 131 is in the closed state, the control unit 35 A signal is sent to the first electric actuator 211, and the first electric actuator 211 is locked and controlled (S205B). When the door opening state is determined in step 204B, the control unit 35 turns on the door opening lamp 63 (S206B) and does not lock and control the first electric actuator 211. Upon seeing the lighting of the door opening lamp 63, the worker closes the opened first door 131 and performs the locking operation.
The same procedure as that for the first door 131 is carried out for the second to sixth doors 132 to 136.

(Procedure when you forget to lock)
When the loading of the bottled soft drink into the truck bed 10 is completed and all the doors are closed, the worker starts the engine to drive the truck to the destination, but if the doors are forgotten to be locked. Is automatically locked, as shown in FIG.
As shown in FIG. 13, when the engine is started, the control unit 35 receives the ignition on detection signal from the ignition on detection mechanism 62 (S301), and checks the opening and closing of the first to sixth doors according to the setting conditions. (S302). Based on the signal output from the first door open / close detection mechanism 231, the control unit 35 determines whether or not the first door 131 is in the closed state (S303). If the first door 131 is in the closed state (Yes), the control unit 35 sends a signal to the first electric actuator 211. If the first door 131 is forgotten to be locked, the first electric actuator 211 is locked and controlled (S304).
On the other hand, when the first door 131 is in the open state, the control unit 35 turns on the door opening lamp 63 (S305), and the first electric actuator 211 is not locked and controlled. It is preferable to generate an alarm sound (alarm) when the door opening lamp 63 is turned on.
After the control of the first electric actuator 211 is completed, the opening / closing of the next door is checked (S306). After that, the same procedure as that for the first door 131 is carried out.

[Delivery]
The worker drives the truck 1 to the destination, and when the destination is reached, the worker replenishes the vending machine with a bottle of soft drink. In this case, since the vehicle is expected to depart in a short period of time, safety can be ensured by not forgetting to lock the door and giving a warning to the worker for the opened door. The procedure will be described below. It should be noted that this work may usually be performed in the ignition on state (the power is on, but the engine cell is not rotating).
(Procedure to lock other closed doors when any door is opened)
With the ignition on, all of the first to sixth electric actuators 211 to 216 are unlocked for shipping bottled soft drinks, and any of the first to sixth doors 131 to 136 is unlocked. Doors, such as the first door 131 and the second door 132, are opened, and other doors, such as the third to sixth doors 133-136, are closed.
As shown in FIG. 14, the first to sixth electric actuators 211 to 216 are unlocked (S401), and the doors of the first door 131 and the second door 132, which are arbitrary doors, are open. It is detected by the door open / close detection mechanism 231 of No. 1 and the second door open / close detection mechanism 232 (S402). The control unit 35 determines whether or not an ignition-on signal has been received from the ignition-on detection mechanism 62 (S403). When the ignition on signal is received (Yes), the opening / closing of the first to sixth doors is checked according to the setting conditions (S404). The control unit 35 determines whether or not the first door 131 is in the closed state based on the signal output from the first door open / close detection mechanism 231 (S405). Since the first door 131 is in the opened state, the control unit 35 turns on the door opening lamp 63 (S406) and does not control the locking of the first electric actuator 211. When the control of the first electric actuator 211 is completed (S407), the next door is checked by step S408. If the ignition on signal is not received (No) in step S403, the flow ends.
Hereinafter, the same procedure as that for the first door 131 is carried out for the second door 132. If the same procedure as described above is performed for the second door 132, the procedure for the third door 133 is performed.
Since the third door 133 is closed, when the control unit 35 receives the detection of the closed state of the third door 133 in step S405 (Yes), the control unit 35 is the third electric actuator. Locking control of 213 (S407). Similarly, since the fourth to sixth doors 134 to 136 are closed, the fourth to sixth electric actuators 214 to 216 are locked and controlled.

(Procedure to lock the closed door when any door is closed)
FIG. 15 shows a flow for checking the opening / closing of the door after the loading of the bottled soft drink is completed. For example, any door, the first door 131 and the second door 132, are in the open state.
As shown in FIG. 15, when the closed state of the first door 131 and the second door 132 is detected by the first door open / close detection mechanism 231 and the second door open / close detection mechanism 232 (S501), the ignition It is determined whether or not the control unit 35 has received the ignition on signal from the on detection mechanism 62 (S502). Upon receiving the ignition on signal (Yes), the control unit 35 locks and controls the electric actuator 21 corresponding to the door determined to be in the closed state, for example, the first electric actuator 211 and the second electric actuator 212 (Yes). S503).
On the other hand, in step S502, unless the control unit 35 receives the ignition on signal from the ignition on detection mechanism 62 (No), the first and second electric actuators 211 and 212 are not locked.

(Procedure to lock the door that has been unlocked for a certain period of time)
Workers may not open the door they plan to open, even if they unlock it.
As shown in FIG. 16, all or part of the first to sixth electric actuators 211 to 216 are unlocked (S601), and are output from the first to sixth door open / close detection mechanisms 231 to 236. The control unit 35 determines whether or not at least a part of the first to sixth doors 131 to 136 is in the open state (S602).
When it is determined (No) that all the doors 131 to 136 of the first to sixth doors are closed (unopened), the control unit 35 determines whether or not a predetermined time or more has passed from the locking (S603). ). If it is determined in step S602 that the door is open (Yes), the process proceeds to step S402 of the flowchart shown in FIG.
If it is determined in step S603 that the predetermined time or more has elapsed (Yes), the opening / closing of the first door 131 is checked (S604). The first door open / close detection mechanism 231 determines whether or not the first door 131 is in the closed state (S605). When the closed state (Yes) of the first door 131 is determined in step S605, the control unit 35 locks and controls the first electric actuator 211 (S606). After the control of the first electric actuator 211 is completed, the opening / closing of the next door is checked (S607). When the door opening state of the first door 131 is determined in step S605, the control unit 35 turns on the door opening lamp 63 (S608) and does not lock and control the first electric actuator 211.
After that, the opening / closing of the second door 132 is checked (S604), and steps S604 to S608 are carried out. Further, steps 604 to S608 are also carried out for the third door 133, the fourth door 134, the fifth door 135, and the sixth door 136.

[Registration of portable operating device]
The worker registers the portable operation device 4 to be used by himself / herself in the control box 3 in the ignition on state in order to load or unload the bottled soft drink in a predetermined position.
The procedure for registering the portable operation device 4 will be described with reference to FIG.
As shown in FIG. 17, when the registration button 34 of the control box 3 is pressed (S701), a signal is sent from the control unit 35 to the determination unit 304, and the determination unit 304 has been pressed for 2 seconds or more. It is determined whether or not (S702), and if the pressed time is 2 seconds or more (Yes), it is determined whether or not the ignition on signal is received from the ignition on detection mechanism 62 (S702). When the ignition on detection signal is received from the ignition on detection mechanism 62 (Yes), the determination unit 304 stores the ID information of the portable operation device 4 in the storage unit 303 according to the registration mode processing (S704).
If the registration button 34 is pressed for less than 2 seconds in step S702 (No), or if the ignition on detection signal from the ignition on detection mechanism 62 is not received in step S703 (No), the ID information is registered. It ends without being done.
Here, the registration mode process in step S704 shifts to the registration mode by pressing the registration button 34 for 2 seconds, and in this state, the unlock button 41 is pressed for 2 seconds or longer to complete the registration.

In the first embodiment, the following effects can be achieved.
(1) The lock system for the truck bed door is an electric actuator 21 provided on each of the plurality of doors 13 for unlocking or locking operation, and an actuator for switching between an on position in which the electric actuator 21 is operated and an off position in which the electric actuator 21 is not operated. When the portable operation device 4 having an operation signal transmitting unit 46 for sending an operation signal for unlocking or locking the operation setting unit 31 and the actuator operation setting unit 31 and the actuator operation setting unit 31 are in the on position. It includes a control unit 35 that sends an operation signal from the operation signal transmission unit 46 to the electric actuator 21. Therefore, the doors selected in advance by the actuator operation setting unit 31 among the plurality of doors 13 can be unlocked or locked by operating the portable operation device 4 at the operator's hand, and the doors can be opened for each door. Doors that do not need to be closed or that do not need to be closed do not need to be unlocked or locked. Moreover, since the electric actuator 21, the door open / close detection mechanism 23, and the control unit 35 for these are provided for each door 13, and the portable operation device 4 is provided, the individual door 13 can be easily opened and closed, and the door 13 can be forgotten to be closed. Can be prevented. Here, it is possible to provide a locking system for unlocking or locking each of the doors 13 according to the number of doors, but in that case, as many portable operation devices as the number of doors are required, and the unlocking and locking can be performed. Although the work becomes complicated, in the first embodiment, since the unlocking and locking of the plurality of doors 13 can be performed by operating one portable operating device 4, the unlocking and locking work becomes easy. Under the declining population, there is a problem of labor shortage even in the transportation business industry, but in this embodiment, it is possible to shorten the working time and reduce the burden on the workers.

(2) The actuator operation setting unit 31 has first to sixth switching mechanisms 311 to 316 for switching between the on position and the off position of the first to sixth electric actuators 211 to 216, and the first to sixth actuators. Since it is composed of a switching device to which a predetermined switching mechanism 311 to 316 and the first to sixth electric actuators 211 to 216 are assigned, the software configuration of the entire locking system can be simplified.

(3) Since the first to sixth switching mechanisms 311 to 316 are provided in the control box 3, the first to sixth switching mechanisms 311 to 316 are provided in the portable operation device 4, as compared with the case where the first to sixth switching mechanisms 311 to 316 are provided in the portable operation device 4. The portable operating device 4 can be miniaturized.

(4) The control box 3 has a fully open operation button 32 and a fully open operation circuit unit 305 for unlocking all of the plurality of electric actuators 21, and a fully closed operation button 33 for locking all of the plurality of electric actuators 21.

In the second embodiment, the operation unit 71 and the display unit 73 may be configured by a touch panel display.

The processor 74 controls the operation unit 71, the on / off setting data memory 72, and the display unit 73.
For example, when an operator sets information on an on position or an off position for each of the first to sixth electric actuators 211 to 216 by the operation unit 71, the processor 74 displays the set information on the display unit 73. It is displayed and the set information is stored in the on / off setting data memory 72. The processor 74 calls the on / off setting data corresponding to the set information from the on / off setting data memory 72, and sends the on / off setting data from the output unit 76 to the control unit 35 through the input unit 301 of the control box 3A.

The flowchart of FIG. 19 includes "checking the opening and closing of the first to sixth doors according to the setting conditions (S104A, S104B)" and "checking the opening and closing of the next door" (S104A, S104B) among the flowcharts shown in FIG. 11 of the first embodiment. S109A, S109B) ”. Although the procedure shown in FIG. 11 but not shown in FIG. 19 is also carried out in the second embodiment, the description thereof will be simplified or omitted here.
First, when there is an unlocking operation request (see FIG. 11), the opening and closing of the first to sixth doors is checked according to the setting conditions (S104A).
Based on the detection signal output from the first door open / close detection mechanism 231, the control unit 35 determines whether or not the first door 131 is in the closed state (S105A). If the first door 131 is in the closed state (Yes), the external setting is made in step S801. The external setting in step S801 means that the actuator operation setting unit 7 provided separately from the control box 3A sets the setting information of the on position or the off position of the first to sixth electric actuators 211 to 216 to the control unit of the control box 3A. To send to 35.

After the external setting, the control unit 35 first determines whether the setting of the first electric actuator 211 is the on position or the off position (S802). If it is in the on position, the control unit 35 sends an operation signal to the first electric actuator 211 to control unlocking of the first electric actuator 211 (S106A).
On the other hand, if the first door 131 is in the open state (No) in step S105A, the control unit 35 turns on the door opening lamp 63 (S108A) and does not unlock the first electric actuator 211. If the first electric actuator 211 is set to the off position in step S802, the unlock control of the first electric actuator 211 is not performed.
After the control of the first electric actuator 211 is completed, the opening / closing of the next door is checked (S109A). That is, the opening / closing of the second door 132 is checked (S104A), and thereafter, the same procedure as that for the first door 131 is carried out.
On the other hand, when there is a lock operation request (see FIG. 11), the opening and closing of the first to sixth doors is checked according to the setting conditions (S104B). After that, steps S104A, S105A, S106A, S107A, S108A, and S109A having the same procedure as the unlocking steps S104A, S105A, S106A, S107A, S108A, and S109A are performed.

In the second embodiment, in addition to the effects of (1), (4) to (11) of the first embodiment, the following effects can be obtained.
(12) Since the actuator operation setting unit is the actuator operation setting unit 7 configured by a computer different from the control box 3, it can be easily controlled by inserting predetermined application software.
(13) If a commercially available smart phone is used as a computer, the actuator operation setting unit can be configured at low cost.
