Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, the case of a security system that monitors a monitoring area set in a building such as a dwelling unit, a store, or a business office is illustrated, but the building in which the monitoring area is set is not limited to these.
The security system is installed in a monitoring area and includes an elevator that carries a conveyance target between multiple floors of a building. The type of elevator is not limited. For example, a table-type small baggage elevator (hereinafter simply referred to as a small baggage elevator) in which the entrances and exits of each floor are provided according to the height of the person's waist may be used. May be a floor-type small baggage elevator provided according to the floor height of each floor, or an elevator that carries humans.

  Hereinafter, the case where the elevator of the embodiment is a table-type parcel elevator will be exemplified. The security system according to the embodiment uses a basket used for storing an object to be transported by a small bag elevator as a storage for a storage object such as valuables. While the basket of the small baggage elevator is used as a storage, the anti-theft performance is improved by stopping the basket at the retracted position where it is retracted from any outlet.

(First embodiment)
Please refer to FIG. The security system 1 is installed in a monitoring area 2 to be monitored, security sensors 3a and 3b for detecting an abnormality, a security device 4 connected to each of the security sensors 3a and 3b, and a monitoring center 7 and a communication line. The center apparatus 8 connected to the security apparatus 4 through NT is provided. Reference numeral 5 indicates the entrance / exit of the building where the monitoring area 2 is set, and reference numeral 6 indicates the building floor between the first floor and the second floor of the building and the building floor between the second floor and the third floor. Indicates the part. Although FIG. 1 shows the case where the building in which the monitoring area 2 is set is a three-story building, the number of floors of the building is not limited to the third floor and may be two or more. That is, it may be the second floor or the fourth floor or more.

  The security sensors 3a and 3b include an indoor sensor installed in the building where the monitoring area 2 is set and an outdoor sensor installed outside the building. The indoor installation sensor includes, for example, a sensor that detects that a window or a door is opened, a sensor that detects a moving body in a room, and the like. Moreover, as a sensor of outdoor installation, the sensor etc. which detect a moving body are contained, for example. The security sensor 3a is provided in addition to the exit route from the security device 4 to the entrance / exit of the monitoring area 2 (for example, the entrance / exit 5 of the building), and the security sensor 3b is provided in the exit route. Hereinafter, the security sensors 3a and 3b may be collectively referred to as “security sensor 3”.

The security sensor 3 may be, for example, a magnet sensor that detects opening / closing of an opening / closing part, or an infrared sensor that detects the presence or absence of an intruder in the detection range based on a change in the amount of received infrared light. The security sensor 3 may be an image sensor that detects the presence or absence of an intruder or the like in the imaging range based on, for example, the difference between the captured image and a normal image stored in advance. The security sensor 3 transmits a detection signal to the security device 4 when an abnormality is detected. Communication between the security sensor 3 and the security device 4 is performed by wire or wireless.
The security device 4 detects the occurrence of an abnormality in the monitoring area 2 based on a detection signal from the security sensor 3.

In the monitoring area 2, a small baggage elevator 10 that carries a conveyance target between a plurality of floors of a building is installed. The small bag elevator 10 includes a cage 16 that can move up and down a hoistway 11 surrounded by a side wall 10a.
The side wall 10a is provided with entrances Da, Db and Dc on the first, second and third floors of the building, respectively. Hereinafter, the outlets Da, Db, and Dc may be collectively referred to as “the outlet D”.

The user can store the small parcel to be transported through the loading / unloading port D on any floor in the basket 16 and take out the small parcel from the cart 16 through the loading / unloading slot D on the floor of the transport destination.
In addition, in the time zone when the monitoring area 2 is unmanned and the parcel elevator 10 is not used as the original conveying means of the elevator, the parcel elevator 10 (especially the basket 16), for example, stores the storage object 90, which is a valuable item or the like. Used as a storage. When the parcel elevator 10 is used as a storage, the basket 16 is moved to the retracted position retracted from any of the loading / unloading ports D and stopped at the retracted position with the storage object 90 stored or loaded in the basket 16. Let The retracted position retracted from any of the access ports D is a position where the cage 16 does not overlap with the access port D as much as possible in the hoistway 11.

Since the hoistway 11 is surrounded by the side wall 10a, the retracted position retracted from the access port D is difficult to access from the outside.
The operation mode of the security device 4 can be set to either a security set mode that outputs a notification signal when a detection signal is received from the security sensor 3 or a security release mode that does not output a notification signal even when a detection signal is received. . Here, the setting of the guard set mode is permitted when the cage 16 is stopped at the retracted position, and the setting of the guard set mode is prohibited when the cage 16 is not stopped at the retracted position. Therefore, while the guard set mode is set, the cage 16 is retracted to the retracted position.

  When the security device 4 is set to the security set mode and the detection signal is received while the cage 16 is stopped at the retracted position, the security device 4 outputs a notification signal to the center device 8 of the monitoring center 7. When a notification signal is output from the security device 4 to the center device 8, the center device 8 notifies this information to the controller or the like. Then, the monitoring center 7 sends a “handling” instruction to the handling personnel. The coping personnel deal with anomalies (intrusion of suspicious persons, fires, etc.) that occurred in the monitoring area 2 while contacting and coordinating with the monitoring center.

Thus, since the security device 4 cannot be set in the security set mode unless the basket 16 for loading the storage object 90 is stopped at the retracted position that is difficult to access from the outside, the storage object 90 in the security set mode cannot be set. Access from outside can be made difficult. For this reason, the theft of the storage object 90 can be physically inhibited to improve the anti-theft property.
In addition, by physically hindering the theft of the storage object 90 and increasing the time required to access the storage object 90, the security device 4 detects the theft before it reaches the theft and promptly detects it. A notification signal can be output to the center device 8.
Further, the stolen property of the storage object 90 can be improved by effectively utilizing it as a facility asset in a time zone when the small baggage elevator 10 is not used.

Then, the structure of each part of the security system 1 is demonstrated.

(Functional structure of small baggage elevator)
Next, the functional configuration of the small bag elevator 10 will be described. Please refer to FIG. The operation panels PNLa to PNLc on each floor include driving operation buttons 30a to 30c and operation panel controllers 40a to 40c, respectively. Three driving operation buttons 30a to 30c are provided corresponding to the first to third floors, and are used to select and instruct a floor (target stop position) on which the car 16 is moved up and down.
That is, when the cage 16 stopped on the floor where the parcel is sent out (hereinafter referred to as the transportation source) is moved up and down to the transportation source (when calling), the basket 16 stopped at the transportation source is small. This is used to select and instruct a floor to be lifted or lowered when it is lifted (sent out) to a floor (hereinafter abbreviated as a transport destination) to which the parcel is sent.

  The driving operation buttons 30a to 30c are connected to the operation panel controllers 40a to 40c, respectively. The operation panel controllers 40a to 40c on each floor are connected to a control panel built in the control box CB by a communication cable, and the operation buttons 30a to 30c are communicated between the operation panel controllers 40a to 40c and the control panel. A lift instruction by 30c is input to the control panel. Further, detection information of the open / close detection unit 44 and detection information of the position detection units 42a to 42c provided on each floor are also input to the control panel. Based on the input information, the control panel is configured to control the operation of the hoisting machine 20 and to perform a lifting control process for moving the cage 16 up and down.

Further, in the small bag elevator 10, the position detection unit 43 that detects that the cage 16 is stopped at the retracted position retracted from any of the entrances Da to Dc, and the storage object 90 are loaded in the cage 16. A load detecting unit 45 for detecting the occurrence of the load.
The position detection unit 43 may be a reed switch that is turned on, for example, when the cage 16 is located at the retracted position. Here, in order to make it difficult for the storage object 90 in the basket 16 to be taken away even if the slot door 24 of the slot D is opened, the retracted position is the opening of the slot D and the slot 16M of the basket 16 (FIG. 3). (See) is set to a position where the overlapping portion is minimized.

  For example, the retreat position is set such that the overlapping portion between the opening of the loading / unloading port D and the loading / unloading port 16M of the basket 16 is completely eliminated. For example, when the cage 16 is retracted below the entrance / exit D, the retracted position is set so that the top panel 16S of the cage 16 in the retracted position is positioned below the lower end of the entrance / exit D. Further, when the car 16 is retracted above the loading / unloading port D, the retracting position is set so that the bottom panel 16F of the car 16 at the retracting position is located above the upper end of the loading / unloading port D.

In the present embodiment, for example, the height of the cage 16 is about 750 to 900 mm, and the retreat position is set at a position shifted by 1000 mm from an appropriate target stop position corresponding to the entrance / exit D on each floor.
The loading detection unit 45 detects the loading of the storage object 90 in the car 16 by detecting the identification information of the storage object 90 loaded in the car 16, for example. The loading detection unit 45 may include a receiver that receives a wireless identification signal transmitted from the storage object 90, for example. For example, the loading detection unit 45 may include a tag reader that reads a radio identification signal transmitted from an RFID (Radio Frequency IDentifier) tag attached to the storage object 90. Further, for example, the stack detection unit 45 may include a barcode reader that reads a barcode attached to the storage object 90.

Further, the parcel elevator 10 receives a retreat operation that is an instruction input for moving to the retreat mode in which the cage 16 is moved to the retreat position and the cage 16 is stopped at the retreat position, and a retreat end operation that ends the retreat mode. An operation authentication unit 46 that authenticates the operation and the evacuation end operation is provided. The operation authentication unit 46 performs, for example, a key switch operated by a dimple key, a numeric keypad for inputting a personal identification number, a card reader for reading a card key, and a retraction operation and a retraction end operation by fingerprint authentication and face authentication technology. An authentication device for authenticating the person may be provided.
For example, the operation authentication unit 46 may be provided near the operation panel PNL on each floor, or may be provided in the operation panel PNL. The operation authentication unit 46 may be provided only on any one of the first to third floors, or may be provided only on all or some of the floors where the entrance / exit D is provided.

Further, the parcel elevator 10 stops the cage 16 at the retracted position in response to the acceptance of the retracting operation in the operation authentication unit 46, shifts the parcel elevator 10 to the retract mode, and retracts in response to the acceptance of the retracting end operation. A sub-control box SCB for ending the mode is provided.
The position detection unit 43, the open / close detection unit 44, and the stack detection unit 45 are connected to the sub control box SCB, and each detection information is input to the sub control box SCB. The opening / closing detectors 44 of each floor are connected to the operation panel controllers 40a to 40c of the operation panels PNLa to PNLc, respectively, and the detection information of the opening / closing detector 44 is input to the sub control box SCB via the control box CB. Also good. The operation authentication unit 46 is connected to the sub control box SCB, and operation information notifying that an authenticated save operation has been performed and that an authenticated save end operation has been performed is input to the sub control box SCB.

The parcel elevator 10 shifts the parcel elevator 10 to the evacuation mode based on the input information, or ends the evacuation mode of the parcel elevator 10.
Reference is made to FIG. The parcel elevator 10 is in a normal mode that is not a retreat mode, and the basket 16 is located at an appropriate target stop position corresponding to the entrance D of any floor. In the example of FIG. 5A, the basket 16 is located at the target stop position corresponding to the first floor entrance / exit Da.

In this state, the storage object 90 is loaded into the car 16 through the loading / unloading port Da, and the retraction operation is performed from the operation authentication unit 46.
When the evacuation operation is performed, the operation authentication unit 46 performs authentication processing of the input evacuation operation. When the authentication of the input save operation is successful, the operation authentication unit 46 inputs operation information notifying that the authenticated save operation has been performed to the sub-control box SCB. If authentication of the input save operation fails, the operation authentication unit 46 does not input operation information notifying that the authenticated save operation has been performed to the sub-control box SCB. For example, the operation authentication unit 46 inputs operation information notifying that the authentication of the performed save operation has failed into the sub control box SCB. In this case, the sub control box SCB does not shift the small bag elevator 10 to the evacuation mode, and notifies the user that the shift to the evacuation mode is not permitted.

Next, the sub-control box SCB determines whether or not the loading detection unit 45 has detected that the storage object 90 is loaded in the basket 16. When the stack detection unit 45 detects that the storage object 90 has been loaded in the basket 16, the sub control box SCB starts a retreat mode transition process for shifting the small bag elevator 10 to the retreat mode. . If the stack detection unit 45 does not detect that the storage object 90 is loaded in the basket 16, the sub control box SCB prohibits the shift to the evacuation mode. That is, the movement of the basket to the retracted position is prohibited.
In the save mode transition process, the sub control box SCB outputs a save instruction signal to the control box CB. The control box CB that has received the retraction instruction signal moves the cage 16 up and down, thereby moving the cage 16 to the retreat position 50 and then stopping it at the retreat position 50 as shown in FIG.

When the basket 16 stops at the retreat position 50, the transition to the retreat mode is completed. The sub control box SCB outputs a mode signal indicating whether or not the small bag elevator 10 is in the evacuation mode to the control box CB and the security device 4. In addition, the detection information of the position detection unit 43, the open / close detection unit 44, and the load detection unit 45 while the small bag elevator 10 is in the retreat mode is output to the security device 4.
When the control box CB receives a mode signal indicating the retreat mode (that is, when the car 16 is stopped at the retreat position 50), the control box CB prohibits the operation operation button 30 from inputting an instruction to raise and lower the car 16. This prevents the car 16 from moving from the retreat position 50 to a position that is easily accessible from the outside, such as the entrance door 24, while the small bag elevator 10 is in the retreat mode, thereby preventing the anti-theft performance from being impaired.

  Next, when the save end operation is performed from the operation authentication unit 46 in the save mode shown in FIG. 5B, the operation authentication unit 46 performs authentication processing of the input save end operation. When the operation authentication unit 46 is provided on a plurality of floors, the floor on which the evacuation end operation is performed and the floor on which the evacuation operation is performed may be different or the same. If the authentication of the input save end operation is successful, the operation authentication unit 46 inputs operation information notifying that the authenticated save end operation has been performed to the sub-control box SCB. In this case, the sub control box SCB outputs a save end instruction signal to the control box CB. The evacuation end instruction signal may include information on the floor on which the evacuation end operation has been performed, or information on the target stop position corresponding to the entrance / exit D of the floor on which the evacuation end operation has been performed.

The control box CB that has received the evacuation end instruction signal raises and lowers the cage 16 to stop the cage 16 at the target stop position corresponding to the entrance / exit D of the floor where the evacuation termination operation is performed. Then, the save mode ends.
If authentication of the input save end operation fails, the operation authentication unit 46 does not input operation information notifying that the authenticated save end operation has been performed to the sub-control box SCB. For example, the operation authentication unit 46 inputs operation information notifying that the authentication of the performed save end operation has failed into the sub control box SCB. In this case, the sub control box SCB does not end the save mode and notifies the user that the end of the save mode is not permitted.

The entrance / exit D is an example of two or more openings provided in the side wall 10a. The door 24 is an example of an open / close door that closes the door D. The hoisting machine 20 is an example of a car driving unit that drives the car 16 up and down along the hoistway 11. The control box CB is an example of an operation control unit that controls the hoist 20 to raise and lower the basket 16.
The driving operation buttons 30 a to 30 c are an example of an operation unit that inputs an instruction to raise and lower the cage 16. The sub-control box SCB moves the cage 16 to the retracted position 50 that is retracted from any of the two or more outlets D provided in the side wall 10a by moving the cage 16 up and down by the control box CB. It is an example of the evacuation control part to be stopped.

Next, the functional configuration of the security device 4 will be described. Please refer to FIG. The security device 4 includes a control unit 60, an input / output unit 61, an operation unit 62, a display unit 63, a communication unit 64, and a storage unit 65.
The operation unit 62 includes a key input unit that is operated to set an operation mode of the security device 4 (for example, a security set mode or a security release mode), and a reading unit that reads user authentication information. Composed. The operation unit 62 allows the operation input after reading the authentication information and collating the user. The operation unit 62 may be configured by providing a touch panel on the liquid crystal monitor of the display unit 63.

  As a reading unit for reading user authentication information (ID (Identification) information), a tag reader for reading a radio signal from an RFID (Radio Frequency Identification) tag, a card reader for reading card information of an IC (Integrated Circuit) card or a magnetic card In addition, biometric information acquisition means for reading biometric information such as fingerprints and face images may be provided as appropriate. In this case, the storage unit 65 stores registration authentication information corresponding to the input authentication information.

The communication unit 64 has a function for communicating with the center device 8. The communication unit 64 is a communication interface for connecting the security device 4 and the center device 8. As described above, the security device 4 and the center device 8 are connected via the public line network or the Internet network as the communication line NT.
The display unit 63 has a function of outputting an operation guide or the like to the user. The display unit 63 can be configured by a liquid crystal display, an indicator lamp, a speaker, and the like. The display unit 63 is installed in the vicinity of the operation unit 62 or is installed integrally with the operation unit 62. An operation guide and menu display are performed by the display unit 63. The operation guide or the like may be performed by voice notification from a speaker.

The input / output unit 61 has a function as an interface to which peripheral devices such as the security sensors 3a and 3b are connected. The input / output unit 61 is operated by security sensors 3a and 3b, disaster prevention sensors such as smoke detectors and heat detectors, and the like disposed at appropriate locations inside / outside the building to be monitored in the security target. Connected with emergency button etc. The input / output unit 61 is a communication interface that receives detection signals from various sensors. Each sensor is assigned a unique identification number, and this identification number (ID number) is included in the detection signal.
The input / output unit 61 has a function as an interface to which the sub control box SCB is connected. The input / output unit 61 detects a mode signal indicating whether or not the small bag elevator 10 is in the retreat mode, and detection by the position detection unit 43, the open / close detection unit 44, and the load detection unit 45 while the small bag elevator 10 is in the retreat mode. Information is received from the sub-control box SCB.

  The storage unit 65 stores information such as sensor information (sensor identification number, etc.), registration authentication information, operation mode history, abnormality history, and the like. In addition, the storage unit 65 operates the security device 4, a program for operating the control unit 60 as the security device 4, sensor information in which the sensor type and the sensor installation position are associated with each sensor ID number, and the security device 4. Registration authentication information for authenticating the user, operation mode history, and abnormality history are stored.

The control unit 60 has a function of performing various controls of the security device 4. As shown in FIG. 6, the control unit 60 includes a mode setting unit 66, an abnormality determination unit 67, and a notification control unit 68.
The mode setting unit 66 determines whether or not the user who inputs the operation on the operation unit 62 is a registered user. For this purpose, the mode setting unit 66 checks whether or not the user ID information acquired from the operation unit 62 matches that registered in advance in the registration authentication information in the storage unit 65. If they match, the user is authenticated as having an operation authority (user authority) as a legitimate user, and the setting of the operation mode of the security device 4 by operation input performed through the operation unit 62 is accepted.
When the user authentication fails, the mode setting unit 66 notifies the user that the operation mode shift is not permitted. For example, the display unit 63 outputs a message indicating that the operation mode transition is not permitted to the user.

When a security set operation, which is a switching operation for switching the operation state of the security device 4 from the security release mode to the security set mode, is performed, the mode setting unit 66 determines whether or not the security sensor 3 has detected an abnormality. To do. When the security sensor 3 detects an abnormality, the mode setting unit 66 does not permit the transition to the security set mode and notifies the user that the transition to the security set mode is not permitted.
Here, when the security device 4 is provided in the monitoring area 2, the security sensor 3b provided in the exit route to the entrance / exit 5 of the monitoring area 2 detects the user who operates the security device 4, You may not be able to enter security set mode. Therefore, when the security set operation is performed, the mode setting unit 66 determines whether or not the security sensor 3a provided outside the exit route has detected an abnormality, and the security sensor 3a has detected the abnormality. In this case, the mode setting unit 66 may be configured to prohibit the transition to the security set mode.

If the security sensor 3 has not detected an abnormality, the mode setting unit 66 determines whether the cage 16 is stopped at the retreat position 50 based on the detection information of the position detection unit 43 received from the sub control box SCB. Judge whether or not. Alternatively, it may be determined from the sub control box SCB that the transition to the evacuation mode has been completed and the cage 16 is stopped at the evacuation position 50. When the basket 16 is not stopped at the retreat position 50, the mode setting unit 66 does not permit the shift to the guard set mode and notifies the user that the shift to the guard set mode is not permitted.
When the basket 16 is stopped at the retreat position 50, the mode setting unit 66 shifts the operation state of the security device 4 from the security release mode to the security set mode. In addition, a delay time is provided until the detection by the security sensor 3b provided in the exit route becomes valid, and the detection by the security sensor 3b is invalidated until the delay time has passed since the transition to the security set mode. A notification signal may not be output upon detection of the user.

In the security set mode, when receiving a detection signal from the sensor, the abnormality determination unit 67 determines whether or not there is an abnormality in comparison with the current mode and the sensor information in the storage unit 65. The abnormality determination unit 67 determines that an abnormality is detected when a detection signal is received from any of various sensors including the security sensor 3 when the security set mode is set, and the fire sensor is set when the security release mode is set. When a detection signal is received from any of the emergency buttons, it is determined that there is an abnormality.
Further, in the security set mode, the abnormality determination unit 67 determines whether or not the entrance / exit door 24 of the small bag elevator 10 in the evacuation mode is opened based on the detection information of the opening / closing detection unit 44 received from the sub control box SCB. . When the entrance door 24 is opened while the security set mode is set, the abnormality determination unit 67 determines that there is an abnormality.

Further, in the security set mode, the abnormality determination unit 67 determines whether or not the basket 16 of the small bag elevator 10 in the retreat mode has moved from the retreat position 50 based on the detection information of the position detection unit 43 received from the sub control box SCB. Determine whether. When the cage 16 moves from the retreat position 50 while the security set mode is set, the abnormality determination unit 67 determines that there is an abnormality.
In the security set mode, the abnormality determination unit 67 determines whether or not the detection of the stacking of the storage object 90 is continued based on the detection information of the stacking detection unit 45 received from the sub control box SCB. When the detection of the loading of the storage object 90 is not continued while the security set mode is set, the abnormality determination unit 67 determines that there is an abnormality.

In the security set mode, the abnormality determination unit 67 determines whether or not the retreat mode of the small bag elevator 10 is continued based on the mode signal received from the sub control box SCB. When the evacuation mode ends while the security set mode is set, the abnormality determination unit 67 determines that there is an abnormality.
When the abnormality determination unit 67 determines that the abnormality has been detected, the notification control unit 68 transmits a notification signal indicating the abnormality to the center device 8 from the communication unit 64. The notification signal may include information on the identification number of the security device 4, the ID number of the sensor that has detected the abnormality, the type of sensor, and its installation position.

(Effect of 1st Embodiment)
(1) The mode setting unit 66 permits the setting of the guard set mode when the cage 16 is stopped at the retracted position 50, and sets the guard set mode when the cage 16 is not stopped at the retracted position 50. Ban. For this reason, the security device 4 cannot be set in the security set mode unless the basket 16 for loading the storage object 90 is stopped at the retreat position 50 that is difficult to access from the outside. Access to the object 90 can be made difficult. For this reason, the theft of the storage object 90 can be physically inhibited to improve the anti-theft property.
In addition, by physically hindering the theft of the storage object 90 and increasing the time required to access the storage object 90, the security device 4 detects the theft before it reaches the theft and promptly detects it. A notification signal can be output to the center device 8.

(2) The sub control box SCB moves the basket 16 to the retreat position 50 when the stack detection unit 45 detects that the storage object 90 is loaded in the basket 16. For this reason, it is possible to prevent the car 16 from being retreated to the retreat position 50 while forgetting to load the storage object 90 on the car 16. Thereby, the anti-theft property of the storage object 90 can be improved.
(3) The control box CB prohibits the input of the raising / lowering instruction of the cage 16 by the driving operation button 30 when the cage 16 is stopped at the retreat position 50. This prevents the car 16 from moving from the retreat position 50 to a position that is easily accessible from the outside, such as the entrance door 24, while the small bag elevator 10 is in the retreat mode, thereby preventing the anti-theft performance from being impaired.

  (4) The abnormality determination unit 67 of the security device 4 moves the cage 16 from the retreat position 50 when the access door 24 is opened while the security set mode is set or when the security set mode is set. If it is determined to be abnormal. As a result, the security device 4 detects the theft and outputs a notification signal to the center device 8 at an early stage while attempting to steal the storage object 90 whose access has been physically blocked for a long time. Can do.

(Second Embodiment)
Next, the second embodiment will be described. The configuration of the security system 1, the parcel elevator 10 and the security device 4 of the second embodiment is the same as the configuration shown in FIGS.
In the second embodiment, the anti-theft property of the storage object 90 is improved by increasing the chance of detecting an intruder who intends to steal the storage object 90 and determining the retreat position of the basket 16 so that the time required for the theft is increased. .
For example, a position closer to the entrance / exit D farthest from the entrance / exit 5 than the entrance / exit D closest to the entrance / exit 5 of the monitoring area 2 is determined as the retreat position. In other words, the distance between the first entrance / exit of the two or more entrances / exits D and the entrance / exit 5 is the distance between the second entrance / exit of the two or more entrances / exits. The distance between the retracted position and the first outlet is shorter than the distance between the retracted position and the second outlet.
By moving the retreat position away from the entrance / exit 5 in this way, it is possible to increase the detection opportunity of an intruder who tries to access the cage 16 at the retreat position and extend the time required for the theft.

Reference is made to FIG. Assume that the entrances Da and Db are provided on the first and second floors of the building, respectively. The same applies when there are three or more outlets D.
When the entrance / exit 5 of the monitoring area 2 is provided on the first floor of the building, the entrance / exit Da is closest to the entrance / exit 5 and the entrance / exit Db is farthest from the entrance / exit 5. That is, the entrance / exit Da is closer to the entrance / exit 5 than the entrance / exit Db. For this reason, the retracted position is set to a position 50a, 50b or 50c closer to the loading / unloading port Db than to the loading / unloading port Da.
Note that the retreat position 50a and the retreat position 50b are positions between the access position Da and the access position Db, and the distance between the retraction position 50a and the access position Db is shorter than the distance between the retraction position 50a and the access position Da. The interval between the retracted position 50b and the access port Db is shorter than the distance between the retracted position 50b and the access port Da. Here, the distance between the retracted position and the entrance / exit D is, for example, the distance in the height direction between the lower end of the cage 16 located at the retracted position and the upper end of the entrance / exit D, and the distance between the cage 16 located at the retracted position. The distance in the height direction between the upper end and the lower end of the entrance / exit D may be any shorter distance.

In addition, when the cage | basket 16 is located in the retreat position 50b, the range of the height direction in which the cage | basket 16 exists overlaps with the range of the height direction in which the building floor part 6 between floors exists. By setting the retreat position 50b in this way, it is possible to make it difficult to access the storage object 90 by making a hole in the side wall 10a at a height where the cage 16 exists.
For example, when the cage 16 is located at the retracted position 50b, the retreat position 50b has the largest overlap between the range in the height direction in which the cage 16 exists and the range in the height direction in which the building floor 6 between the floors exists. May be set to be For example, when the width in the height direction of the cage 16 is larger than the thickness of the building floor 6, the range in the height direction in which the building floor 6 exists is completely included in the range in the height direction in which the cage 16 exists. May be set to When the width in the height direction of the cage 16 is smaller than the thickness of the building floor 6, the range in the height direction in which the cage 16 exists is completely included in the range in the height direction in which the building floor 6 exists. May be set to
The retreat position 50c is a position on the opposite side of the loading / unloading port Da with respect to the loading / unloading port Db. In order to secure the retreat position 50c, a space 10b may be provided above the entrance / exit Db, and the whole or a part of the cage 16 may be retreated in the space 10b.

On the other hand, when the entrance / exit 5 of the monitoring area 2 is provided on the second floor of the building, the entrance / exit Db is closer to the entrance / exit 5 than the entrance / exit Da. For this reason, the retracted position is set to a position 50d or 50e closer to the loading / unloading port Da than to the loading / unloading port Db.
The retracted position 50d is a position between the entrance / exit port Da and the entrance / exit port Db, and the interval between the retracted position 50d and the entrance / exit port Da is shorter than the interval between the retracted position 50d and the entrance / exit port Db. The retreat position 50e is a position on the opposite side of the loading / unloading port Db across the loading / unloading port Da. In order to secure the retreat position 50e, a pit 10c may be provided below the entrance / exit Da, and the whole or a part of the cage 16 may be retreated in the pit 10c.

When three or more entrances / exits D are provided, for example, a retreat position may be set between the entrance / exit D furthest from the entrance / exit 5 and the entrance / exit D furthest away from the entrance / exit 5.
That is, the three or more entrances / exits D include the first to third entrances / exits, and the distance between the second entrance / exit and the entrance / exit 5 is the distance between each of the 3 or more entrances / exits D and the entrance / exit 5. The distance between the third entrance / exit and the entrance / exit 5 is the second among the distances between each of the 3 or more entrances / exits D and the entrance / exit 5 If it is long, the retracted position may be located between the second inlet / outlet and the third inlet / outlet.

Reference is made to FIG. Assume that the entrances Da to Dc are provided on the first to third floors of the building, respectively. When the entrance / exit 5 of the monitoring area 2 is provided on the first floor of the building, the entrance / exit Da is closest to the entrance / exit 5. The entrance / exit Dc is farthest from the entrance / exit 5, and the entrance / exit Db is the second farthest from the entrance / exit 5. In other words, the distance between the entrance / exit Dc and the entrance / exit 5 is the longest of the distances between the entrances / outlets Da to Dc and the entrance / exit 5, and the distance between the entrance / exit Db and the entrance / exit 5. Is the second longest in the distance between each of the entrances Da to Dc and the entrance 5.
Therefore, by setting a retracted position between the inlet / outlet Db and Dc, a position closer to the inlet / outlet Dc farthest from the inlet / outlet 5 than the inlet / outlet Da closest to the inlet / outlet 5 is determined as the retracted position. For the same reason, when the entrance / exit 5 of the monitoring area 2 is provided on the third floor of the building, a retreat position is set between the entrances / exits Da and Db.

(Effect of 2nd Embodiment)
(1) A position closer to the entrance / exit D farthest from the entrance / exit 5 than the entrance / exit D closest to the entrance / exit 5 of the monitoring area 2 is determined as the retreat position. When three or more entrances / exits D are provided, for example, the position between the entrance / exit D furthest from the entrance / exit 5 and the entrance / exit D furthest from the entrance / exit 5 is determined as the retreat position.
By setting the retreat position in this manner, the retreat position can be moved away from the entrance / exit 5, and an opportunity for detection of an intruder who intends to steal the storage object 90 can be increased and the time required for the theft can be extended. As a result, the anti-theft property of the storage object 90 can be improved.

(Third embodiment)
Subsequently, the third embodiment will be described. In the third embodiment, it is difficult for an intruder who intends to steal the storage object 90 to predict the retracted position of the basket 16, thereby improving the anti-theft property of the storage object 90. For this reason, the retreat position of the basket 16 is set at random.
Please refer to FIG. The functional configuration of the parcel elevator 10 according to the third embodiment has a functional configuration similar to the functional configuration according to the first embodiment described with reference to FIG. 4, and the same reference numerals are assigned to similar components. . The other configurations of the small bag elevator 10 and the configurations of the security system 1 and the security device 4 are the same as the configurations shown in FIGS. 1 to 3 and 6.

The sub-control box SCB includes a random number generation unit 70 that generates a random number when the operation authentication unit 46 accepts a retraction operation, and a retraction position determination that randomly determines a retraction position according to the random number generated by the random number generation unit 70. The unit 71 is provided.
The evacuation position determination unit 71 determines the evacuation position of the cage 16 at a random position away from the entrance / exit D (retracted from the entrance / exit D) according to the random number generated by the random number generation unit 70. For example, within the range of the position of the cage 16 where the overlap between the opening of the entrance / exit D and the entrance / exit 16M (see FIG. 3) of the cage 16 is completely eliminated, different positions are saved according to the random number generated by the random number generator 70. Set as position.

  For example, the retreat position determination unit 71 may select any one of a plurality of predetermined candidate positions as the retreat position according to the random number generated by the random number generation unit 70. Reference is made to FIG. A plurality of candidate positions are determined one by one at predetermined positions between floors, such as a position 50g between the first floor and the second floor, a position 50f between the second floor and the third floor, and the floor where each candidate position exists. The position of the candidate position may be designated according to the interval.

In this case, the candidate for the evacuation position is the central position between the floors, that is, the central position between two outlets D that are continuously arranged (Da and Db or Db and Dc in the example of FIG. 13A). You may decide to. In this case, it becomes difficult to access from any of the two entrances / outlets D closest to the retracted position, and the anti-theft property can be improved.
Further, the candidate for the retreat position may be set at a position that is offset from the center position of the two outlets D that are continuously arranged. In this case, it becomes more difficult for an intruder to predict whether any of the access ports D can access the cage 16 stopped at the retracted position, and thus the anti-theft property of the storage object 90 can be improved. A plurality of candidate positions may be defined between one floor.

  When randomly selecting a retreat position from a plurality of predetermined candidate positions, the sub-control box SCB is provided with a plurality of position detection units such as reed switches provided on the lifting path L corresponding to these candidate positions. It may be detected whether the cage 16 is stopped at the retracted position. Further, the sub control box SCB may detect whether or not the cage 16 is stopped at the retracted position based on the amount of winding of the hoisting rope 19 by the hoisting machine 20.

Correspondence between the random number generated by the random number generation unit 70 and the position of the cage 16 on the hoistway 11 is determined in advance, and the retreat position determination unit 71 is configured based on the random number generated by the random number generation unit 70. May be set as the retreat position.
Reference is made to FIG. The range R1 is a retractable range in which the overlapping portion between the opening 16M and the opening D of the cage 16 located between the first floor and the second floor is completely eliminated, and the range R2 is the second floor and the third floor. This is a retractable range in which the overlapping portion between the opening / closing port 16M of the cage 16 and the opening of the loading / unloading port D located between them is completely eliminated.

For example, if the integer random number generated by the random number generation unit 70 is expressed as Rnd, the retreat position Pr may be calculated based on the following relational expression.
When N0 ≦ Rnd <N1, the retracted position Pr = a × Rnd
When N1 ≦ Rnd ≦ N2, the retracted position Pr = a × (Rnd + b)
Here, N0, N1, N2, a, and b are the lower limit position 50h of the retractable range R1 when Rnd = N0, and the retracted position Pr is within the retractable range R1 when Rnd = (N1-1). Is set such that when Rnd = N1, the retracted position Pr is the lower limit position 50j of the retractable range R2, and when Rnd = N2, the retracted position Pr is the upper limit position 50k of the retractable range R2.
In this case, the sub control box SCB may detect whether or not the cage 16 is stopped at the retracted position based on the amount of winding of the hoisting rope 19 by the hoisting machine 20.

  At the time of accepting the retreat operation, the retreat position determination unit 71 may determine the retreat position according to how the user operates the operation authentication unit 46 and the driving operation button 30. For example, the retraction position determination unit 71 may select any one of a plurality of predetermined candidate positions as the retraction position according to the number input with a numeric key provided in the operation authentication unit 46. Further, for example, a correspondence relationship between the number input with the numeric keypad and the position of the cage 16 on the hoistway 11 is determined in advance, and the retreat position determination unit 71 is determined according to the correspondence relationship based on the number input with the numeric keypad. The position may be set as the retracted position.

Next, an example of the operation of the small bag elevator 10 of the third embodiment when shifting to the evacuation mode will be described. Refer to FIG. Steps S60, S61, S62, and S66 are the same as steps S10, S11, S12, and S14 described with reference to FIG. If the loading of the storage object 90 is detected in step S62 (step S62: Y), the process proceeds to step S63.
In step S63, the random number generation unit 70 generates a random number. In step S <b> 64, the retraction position determination unit 71 randomly determines a retraction position according to the random number generated by the random number generation unit 70. In step S65, the sub-control box SCB performs a evacuation mode transition process for causing the small bag elevator 10 to transition to the evacuation mode, and the control box CB moves the cage 16 to the determined evacuation position and stops it at the evacuation position. Thereafter, the process ends.

(Effect of the third embodiment)
The retraction position determination unit 71 randomly determines a retraction position according to the random number generated by the random number generation unit 70. For this reason, it becomes difficult for an intruder who intends to steal the storage object 90 to foresee the retreat position of the basket 16, and the anti-theft property of the storage object 90 can be improved.

(Modification)
When the space between two consecutively placed entrances D is narrow and these entrances D are provided so as to open in the same direction, the door frame 33 that guides the opening and closing of the entrance door 24 in the vertical direction (FIG. 2). See) may interfere with each other. For this reason, these entrances / exits D may be provided so that the opening directions are different from each other.
Refer to FIG. For example, the first entrance / exit Da is provided on the first floor, and the second entrance / exit Dd is provided on the second floor. In such a case, the distance Rp between the first inlet / outlet port Da and the second inlet / outlet port Dd is shorter than the vertical length of the door 24 (that is, shorter than the width H of the cage 16 in the height direction). )Sometimes.

For this reason, the second loading / unloading port Dd has a direction in which the first loading / unloading port Da opens so that the door frame 33 of the first loading / unloading port Da and the door frame 33 of the second loading / unloading port Dd do not interfere with each other. It is provided to open in the opposite direction. In other words, the first inlet / outlet port Da and the second outlet / inlet port Dd open in two so-called through directions.
The direction in which the first loading / unloading port Da opens differs from the direction in which the second loading / unloading port Dd opens by 90 degrees, that is, the first loading / unloading port Da and the second loading / unloading port Dd are opened in two orthogonal directions. May be provided.

  In such a case, the distance Rp between the first inlet / outlet port Da and the second inlet / outlet port Dd is shorter than the width H of the cage 16 in the height direction. In this case, if the cage 16 is retracted between the entrances Da and Dd, an overlapping portion of the entrance 16M of the cage 16 and the opening of the entrance D is generated, and if the entrance D is opened, the cage 16 is opened. Easy access. Therefore, in such a case, the entire range between the access ports Da and Dd may be set as a retreat prohibition range in which the cage 16 cannot retreat.
