When the first door 131 is closed and a lock signal is sent from the control box 3 to the first electric actuator 211, the arm 21B of the first electric actuator 211 moves in the opposite direction, that is, clockwise. , and the slider 271 descends. The pin 272, which descends together with the slider 271, rotates the lock cam 274 in the reverse direction via the limiter spring 273 to engage with the lock recess 264B (see FIG. 3).

When the first door 131 is in the open state (see FIG. 7B), if the portable operation device 4 is erroneously operated and a locking signal is sent to the first electric actuator 211, the lock signal is sent to the first electric actuator 211. ), the arm 21B rotates clockwise, the slider 271 descends, and the lock cam 274 comes into contact with the engaging portion 264. As shown in FIG. 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 biasing force of the limiter spring 273, thereby preventing the lock cam 274 and the engaging portion 264 from being damaged. be.
On the other hand, when the unlock signal is sent to the first electric actuator 211 while the first door 131 is closed, the slider 271 rises as shown in FIG. 8B, but the lock cam 274 is locked. Inconvenience of being caught in the recess 264B may occur. Even if such an inconvenience occurs, the pin 272 provided on the slider 271 rises against the biasing force of the limiter spring 273, thereby preventing the lock cam 274 and the engaging portion 264 from being damaged.

Next, a method of unlocking with a key held by a worker will be described with reference to FIG. 9(A).
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, so that the lock cam 274 rotates and the engaging portion 264 is closed. Move away from 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 in the driving portion of the first electric actuator 211 as the slider 271 rises, and the slider 271 rises smoothly.
A method of locking with a key held by a worker 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 rotates. pushes down the lower engaging surface 271B of the two engaging surfaces 271B of the slider 271 . A pin 272 provided at the bottom 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 264 B 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.
10, the information processing section 300 of the control box 3 includes a control section 35, an input section 301, an output section 302, a storage section 303, a determination section 304, a fully open operation circuit section 305, and a fully closed operation circuit section 306. It is
The input unit 301 inputs signals from the antenna 61 , the first to sixth door opening/closing 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 predetermined processing according to 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 illustrated, and the illustration of the second to fifth is omitted.

A storage unit 303 stores ID information of a 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 long pressed, the registered ID information is registered. The registration of the ID information is cancelled. 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 .
Determination unit 304 determines whether the signal sent from portable operation device 4 is for a pre-registered portable operation device 4. If the signal from portable operation device 4 is registered, the portable operation device It allows the operation signal received by the input unit 301 from the operation device 4 to be sent to the control unit 35, and prevents the operation signal from being sent to the control unit 35 if it is not registered.

When at least one of the first to sixth switching mechanisms 311 to 316 is set to the ON position, the control unit 35 receives a signal from the portable operation device 4 and switches the first to sixth switching mechanisms 311 to 316 to the ON position. The first to sixth electric actuators 211 to 216 corresponding to the sixth switching mechanisms 311 to 316 are operated. In other words, the control unit 35 controls that the unlocking button 41 is pressed while 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. Upon receipt of the operation signal transmitted by the output unit 302, a signal for unlocking operation is transmitted to the first electric actuator 211 through the output unit 302. On the other hand, when the lock button 42 is pushed and an operation signal transmitted is received, a signal for locking operation is sent to the first electric actuator 211 through the output section 302 . The determination unit 304 determines the difference between the operation signal transmitted when the unlock button 41 is pressed and the operation signal transmitted when the lock button 42 is pressed.

In the first embodiment, when the full-open operation button 32 of the control box 3 is pressed, the signal is sent to the full-open operation circuit unit 305, and the full-open operation circuit unit 305, via the control unit 35, controls the first to sixth All of the electric actuators 211 to 216 are operated to unlock.
When the full-close operation button 33 is pressed, the signal is sent to the full-close operation circuit unit 306, and the full-close operation circuit unit 306 controls all of the first to sixth electric actuators 211 to 216 via the control unit 35. to perform the locking operation.
A signal from the ignition-on detection mechanism 62 is sent to the control section 35 via the input section 301 .

The information processing unit 400 of the portable operation device 4 includes an operation signal generation unit 45 that generates operation signals for operating the first to sixth electric actuators 211 to 216, and the operation signals generated by the operation signal generation unit 45. and an operation signal transmitter 46 for sending 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 transmits an operation signal for unlocking operation to the information processing unit 300 when the lock button 42 is pressed. 300, an operation signal for locking operation is transmitted.
The operation signal generator 45 lights the LED of the lighting unit 43 when the unlock button 41 or the lock button 42 is pressed. The operation signal generator 45 lights a blue LED when the capacity of the battery 44 is greater than a predetermined value, and lights a red LED to prompt replacement of the battery 44 when the capacity is less than the predetermined value.

Next, the operation of the lock system of the first embodiment will be described with reference to the flow charts of FIGS. 11 to 17. FIG.
[Delivery base station]
The operation of loading bottled soft drinks at the delivery base station will be described with reference to the flow charts of FIGS. 11 to 13. FIG.
To load the truck bed 10 with bottled soft drinks, the worker opens some or all of the first to sixth doors 131-136. It should be noted that the engine of the truck 1 is normally turned off when loading cargo at the base station.

(Procedure for opening and closing some doors)
Here, a first door 131 and a second door 132 are illustrated as some doors that need to be opened. The procedure for opening and closing 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 a bottled soft drink onto the truck bed 10, the operator in the driver's seat 11 must open the first door 131 and the second door 131 of the control box 3. The first switching mechanism 311 and the second switching mechanism 312 corresponding to 132 are switched to the ON position, and the third to sixth switching mechanisms 313 to 313 to 136 corresponding to the third to sixth doors 133 to 136 that do not need to be opened. Leave 316 in the off position.
Then, the worker gets off the driver's seat 11 , moves in front of the first door 131 and the second door 132 , and presses the unlock button 41 of the portable operating device (remote controller) 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 unlocking button 41 is pushed, the operation signal transmitted from the operation signal transmission section 46 is sent to the input section 301 of the control box 3 .
An operation signal input to the input section 301 is sent to the determination section 304 via the control section 35 . The determination unit 304 performs ID collation based on the ID information to determine 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 ID collation, when the ID information of the operation signal sent from the portable operation device 4 matches the registered ID information (Yes), the operation signal sent from the operation signal transmission unit 46 is transmitted to the unlock button 41 . The control unit 35 determines whether the operation request is for "unlocking" when is pressed or "locking" when the lock button 42 is pressed (S103). If the IDs do not match as a result of ID collation (No), the flow ends.
If the operation request in step S103 is "unlock", the opening/closing of the first door is checked according to the set 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 closed in step S105A. If the first door 131 is closed (Yes), it is determined whether the first switching mechanism 311 is on or off (S106A). If the first switching mechanism 311 is at the ON position, the controller 35 sends an operation signal to the first electric actuator 211 to unlock the first electric actuator 211 (S107A).

On the other hand, in step S105A, based on the detection signal from the first door opening/closing detection mechanism 231, if it is determined that the first door 131 is not closed (No), that is, if it is determined that the door is open, the control unit 35 , the door open lamp 63 is turned on (S108A), and the first electric actuator 211 is not unlocked.
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 procedures as those relating to the first door 131 are performed.
Subsequently, the opening/closing of the third door 133 is checked according to the set conditions (S104A). If it is determined in step S105A that the third door 133 is closed, it is determined whether the third electric actuator 213 is at the ON position or the OFF position (S106A).
Since the third door 133 is not scheduled 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, a procedure similar to that for the third door 133 is performed.

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

(Procedure for opening and closing all doors)
Workers may open and close all doors to load bottled soft drinks. In this case, the operator follows the flowchart shown in FIG. 12 to open and close the door.
As shown in FIG. 12, the worker operates the full-open/full-close setting means 30A to load the bottled soft drink onto the truck bed 10 (S201). In order to open all the doors, the worker pushes the full open operation button 32 as an operation of the full open full close setting means 30A. 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 pushed button is the fully open operation button 32, the opening/closing of the first to sixth doors is checked according to the set conditions (S203A).
The controller 35 determines whether or not the first door 131 is closed based on the detection signal output from the first door open/close detection mechanism 231 (S204A). If the first door 131 is closed (Yes), an operation signal is sent from the controller 35 to the first electric actuator 211, and the first electric actuator 211 is unlocked (S205A). If the first door 131 is open, the control unit 35 turns on the open door lamp 63 (S206A), and does not perform the unlocking control of the first electric actuator 211 again.
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 open state of the second door 132 are checked (S204A), and thereafter, the same procedure as that for the first door 131 is performed.

With the first to sixth electric actuators 211 to 216 unlocked, the worker opens all of the first to sixth doors 131 to 136 and loads bottled soft drinks.
When the operation of loading the bottled soft drinks is completed, the operator closes all the first to sixth doors 131 to 136, gets into the driver's seat 11, and operates the fully open/fully closed setting means 30A (S201). . The operator presses the full-close 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). (S203B).
Based on the signal output from the first door open/close detection mechanism 231, it is determined whether or not the first door 131 is closed (S204B). A signal is sent to the first electric actuator 211, and the first electric actuator 211 is locked (S205B). When it is determined in step 204B that the door is open, the controller 35 turns on the door open lamp 63 (S206B) and does not lock the first electric actuator 211 . The operator sees the lighting of the door open lamp 63, closes the opened first door 131, and locks it.
The same procedure as that for the first door 131 is performed for the second to sixth doors 132-136.

(Procedure in case of forgetting to lock)
When the loading of bottled soft drinks 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. are also automatically locked as shown in FIG.
As shown in FIG. 13, when the engine is started, the control unit 35 receives an ignition-on detection signal from the ignition-on detection mechanism 62 (S301), and checks whether the first to sixth doors are opened or closed according to the set conditions. (S302). Based on the signal output from the first door open/close detection mechanism 231, the controller 35 determines whether or not the first door 131 is closed (S303). If the first door 131 is closed (Yes), the controller 35 sends a signal to the first electric actuator 211 . If the locking of the first door 131 is forgotten, the locking of the first electric actuator 211 is controlled (S304).
On the other hand, if the first door 131 is open, the controller 35 turns on the open door lamp 63 (S305), and the first electric actuator 211 is not locked. It is preferable to generate an alarm when the door open lamp 63 is turned on.
After the control of the first electric actuator 211 is finished, the opening/closing of the next door is checked (S306). After that, the same procedure as that for the first door 131 is performed.

[During delivery]
The worker drives the truck 1 to the destination, and when the destination is reached, the vending machine is refilled with bottled soft drinks. In this case, since the vehicle is expected to depart in a short period of time, safety is ensured by not forgetting to lock the door and by issuing a warning to the operator about the open door. The procedure will be described below. This work is usually done with the ignition on (the power is on but the engine cells are not running).
(Procedure for locking other closed doors when any door is opened)
With the ignition on, all of the first through sixth electric actuators 211-216 are unlocked and any of the first through sixth doors 131-136 are unlocked for shipment of bottled soft drinks. Doors, for example, the first door 131 and the second door 132 are opened, and other doors, for example, the third to sixth doors 133 to 136 are closed.
As shown in FIG. 14, the first to sixth electric actuators 211 to 216 are unlocked (S401), and the open state of the first door 131 and the second door 132, which are arbitrary doors, is the first. It is detected by the first door open/close detection mechanism 231 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). If the ignition-on signal has been received (Yes), the opening/closing of the first to sixth doors is checked according to the set conditions (S404). The controller 35 determines whether or not the first door 131 is closed based on the signal output from the first door open/close detection mechanism 231 (S405). Since the first door 131 is open, the controller 35 turns on the open door lamp 63 (S406) and does not perform locking control of the first electric actuator 211. FIG. After the control of the first electric actuator 211 is completed (S407), the next door is checked in step S408. If the ignition-on signal is not received in step S403 (No), the flow ends.
Thereafter, a procedure similar to that for the first door 131 is performed for the second door 132 . After a procedure similar to that described above has been performed with respect to the second door 132, a procedure with respect to the third door 133 is performed.
Since the third door 133 is closed, in step S405, when the control unit 35 receives detection of the closed state of the third door 133 (Yes), the control unit 35 operates the third electric actuator 213 is locked (S407). Similarly, since the fourth to sixth doors 134 to 136 are closed, the fourth to sixth electric actuators 214 to 216 are locked.

(Procedure for locking the closed door when an arbitrary door is closed)
FIG. 15 shows the flow of checking the opening and closing of the door after the shipment of bottled soft drinks is completed. For example, arbitrary doors, the first door 131 and the second door 132, are open.
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 opening/closing detection mechanism 231 and the second door opening/closing detection mechanism 232 (S501), the ignition is turned on. It is determined whether or not the control unit 35 has received an ignition ON signal from the ON detection mechanism 62 (S502). When the ignition-on signal is received (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 ( S503).
On the other hand, if the control unit 35 does not receive the ignition-on signal from the ignition-on detection mechanism 62 in step S502 (No), the locking control of the first and second electric actuators 211 and 212 is not performed.

(Procedure for locking a door that has been unlocked for a certain period of time)
A worker may unlock a door that he or she intends to open, but not open it.
As shown in FIG. 16, all or part of the first to sixth electric actuators 211 to 216 are unlocked (S601), and the first to sixth door opening/closing detection mechanisms 231 to 236 output Based on the signal, the control unit 35 determines whether or not at least some of the first to sixth doors 131 to 136 are open (S602).
When it is determined that all of the first to sixth doors 131 to 136 are in the closed state (unopened) (No), the control unit 35 determines whether or not a predetermined time or more has elapsed since locking (S603). ). If it is determined in step S602 that the door has been opened (Yes), the flow proceeds to step S402 of the flowchart shown in FIG.
If it is determined in step S603 that the predetermined time or more has passed (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 closed (S605). When it is determined in step S605 that the first door 131 is closed (Yes), 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 it is determined in step S605 that the first door 131 is open, the controller 35 turns on the door open lamp 63 (S608) and does not lock the first electric actuator 211. FIG.
After that, the opening/closing of the second door 132 is checked (S604), and steps S604 to S608 are performed. Further, steps 604 to S608 are also performed for the third door 133, fourth door 134, fifth door 135, and sixth door 136. FIG.

[Registration of portable operation device]
In order to load or unload bottled soft drinks at a predetermined position, the worker registers the portable operation device 4 that he/she uses in the control box 3 with the ignition turned on.
A 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 detects that two seconds or more have passed since the button was pressed. (S702), and if the pressed time is 2 seconds or longer (Yes), it is determined whether or not an ignition-on signal has been 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 causes the storage unit 303 to store the ID information of the portable operation device 4 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, in the registration mode processing in step S704, pressing the registration button 34 for two seconds shifts to the registration mode, and in this state, pressing the unlock button 41 for two seconds or more completes the registration.

The following effects can be obtained in the first embodiment.
(1) A locking system for a door for a truck bed includes an electric actuator 21 provided for each of a plurality of doors 13 for unlocking or locking operation, and an actuator for switching between an ON position where the electric actuator 21 is operated and an OFF position where the electric actuator 21 is not operated.

(6) A door open/close detection mechanism 23 that outputs a detection signal for detecting the door open state and the door closed state to the control unit 35, and an ignition on detection mechanism 62 that detects an ignition on signal and outputs it to the control unit 35. In addition, the control unit 35 controls the electric actuator 21 of any door, for example, the door other than the door for which the detection signal of the open state of the first and second doors 131 and 132 is detected by the door opening/closing detection mechanism 23, that is, , to the third to sixth electric actuators 213 to 216 corresponding to the third to sixth doors 133 to 136, so that the doors other than the open doors can be automatically locked. can.

(7) The control unit 35 controls the first and second electric actuators 211 and 212 of any door, for example, the first and second electric actuators 211 and 212 of the door for which the detection signal of the closed state of the first and second doors 131 and 132 is detected. , a lock signal is sent, so the closed door can be automatically locked when the ignition is on.
(8) The control unit 35 locks the electric actuator of the closed door when the predetermined time or more has passed since the lock, so that the door is not forgotten to be locked and is safe.

(9) A latch mechanism 24 that can advance and retreat between an advanced position where the door side engaging portion 242 engages with the body side engaging portion 241 and a retracted position where it disengages, and a door side engaging portion connected to the latch mechanism 24. 242 to advance and retreat positions, a flush handle 26 connected to the connection mechanism 25 to advance and retreat the door-side engaging portion 242, and the first to sixth electric actuators 211-216. A lock mechanism 27 for blocking or permitting operation of the flash handle 26 corresponding to locking or unlocking is provided.

{Second embodiment}
Next, a second embodiment of the invention will be described with reference to FIGS. 18 and 19. FIG.
The second embodiment differs from the first embodiment in the configuration of the actuator operation setting section, and the rest of the configuration is the same as the first embodiment. Here, in the description of the second embodiment, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
FIG. 18 shows a block diagram of the lock system of the second embodiment.
As shown in FIG. 18, the actuator operation setting unit 7 of the second embodiment is configured by a portable computer such as a smart phone, tablet terminal, etc., and the driving application of the second embodiment is installed. Incidentally, in the first embodiment, the first to sixth switching mechanisms 311 to 316 constituting the actuator operation setting section are omitted from the control box 3A of the second embodiment.
Moreover, when using a smart phone as a computer, predetermined application software is downloaded in order to perform the operations described in this embodiment.

The actuator operation setting section 7 includes an operation section 71 , an on/off setting data memory 72 , a display section 73 , a processor 74 , an input section 75 and an output section 76 .
The operation unit 71 sets the ON position or OFF position for each of the first to sixth electric actuators 211 to 216 .
The ON/OFF setting data memory 72 stores ON positions or OFF positions set by the operation unit 71 corresponding to the first to sixth electric actuators 211 to 216 respectively. 216 are stored as on/off setting data corresponding to each.
The display unit 73 displays the ON position or OFF position set corresponding to each of the first to sixth electric actuators 211 to 216 .
In the second embodiment, the operation section 71 and the display section 73 may be configured by a touch panel display.

Processor 74 controls operation unit 71 , on/off setting data memory 72 , and display unit 73 .
For example, when the operator sets the ON position or OFF position information for each of the first to sixth electric actuators 211 to 216 using the operation unit 71, the processor 74 displays the set information on the display unit 73. The displayed and 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 it from the output section 76 to the control section 35 through the input section 301 of the control box 3A.
The control section 35 of the control box 3 controls the operation of the electric actuator 21 based on the setting of the actuator operation setting section 7 and the operation signal from the portable operation device 4 .

In the second embodiment, the actuator operation setting section 7 sends an operation signal output from the portable operating device 4 to the control section 35 of the control box 3A.
In other words, the input unit 75 of the actuator operation setting unit 7 inputs an operation signal sent from the portable operation device 4 and sends it to the processor 74 . The processor 74 sends an operation signal from the output section 76 to the control section 35 of the control box 3A. Here, the signal sent from the portable operation device 4 to the input unit 75 is a Bluetooth standard wireless signal. Note that this signal may be a signal other than the Bluetooth standard.
In addition, in the second embodiment, the operation signal may be sent directly from the portable operation device 4 to the control unit 35 without going through the actuator operation setting unit 7 . That is, the actuator operation setting unit 7 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, and the portable operation device 4 transmits the data without going through the actuator operation setting unit 7. , to the control unit 35 of the control box 3A.
Also, in the second embodiment, the portable operation device 4 and the actuator operation setting section 7 may be configured from one computer. That is, the functions of the portable operation device 4 may be incorporated into the computer that constitutes the actuator operation setting section 7 .

Next, the operation of the lock system of the second embodiment will be explained based on the flow chart of FIG.
The flow chart of FIG. 19 corresponds to "Check opening/closing of the first to sixth doors according to the set conditions (S104A, S104B)" and "Check opening/closing of the next door (S104A, S104B)" in the flow chart shown in FIG. 11 of the first embodiment. S109A, S109B)”. Procedures shown in FIG. 11 but not shown in FIG. 19 are also performed in the second embodiment, but descriptions thereof are simplified or omitted here.
First, when there is an unlocking operation request (see FIG. 11), the opening/closing of the first to sixth doors is checked according to the set conditions (S104A).
Based on the detection signal output from the first door open/close detection mechanism 231, the controller 35 determines whether or not the first door 131 is closed (S105A). If the first door 131 is closed (Yes), external setting is performed in step S801. The external setting in step S801 means that the actuator operation setting section 7, which is provided separately from the control box 3A, sets the ON position or OFF position setting information of the first to sixth electric actuators 211 to 216 to the control section of the control box 3A. It is 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 unlock the first electric actuator 211 (S106A).
On the other hand, if the first door 131 is open in step S105A (No), the control unit 35 turns on the door open lamp 63 (S108A) and does not perform the unlocking control of the first electric actuator 211 . In step S802, if the first electric actuator 211 is set to the OFF position, the first electric actuator 211 is not controlled to unlock.
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 procedures as those relating to the first door 131 are performed.
On the other hand, if there is a lock operation request (see FIG. 11), the opening/closing of the first to sixth doors is checked according to the set conditions (S104B). After that, steps S104A, S105A, S106A, S107A, S108A, and S109A of procedures equivalent to steps S104A, S105A, S106A, S107A, S108A, and S109A of unlocking are performed.

In addition to the effects (1), (4) to (11) of the first embodiment, the second embodiment can also achieve the following effects.
(12) Since the actuator operation setting section 7 is composed of a computer separate from the control box 3, predetermined application software can be installed and control can be easily performed.
(13) If a commercially available smart phone is used as a computer, the actuator operation setting section can be configured at low cost.
