Description

The present invention relates to a parking reservation display device.

There is a craving for a parking lot that can be parked where and when it is needed, with no difference between public, private, or individuals. For example, it is preferable that the parking section closest to the entrance of a building of a public facility such as a hospital is always free for persons with physical disabilities and emergency patients. Similarly, private parking lots and monthly parking lots are also vacant when returning home. However, it may not be used in private parking lots or monthly parking lots while going out, and depending on the time of day, it may not be effectively used even if there is an empty parking space. In addition, although there is a full parking lot, there is a free parking lot and the parking lot is not always effectively used. In particular, the lack of parking has not been resolved in urban areas. In addition, there is a current situation where nuisances such as unauthorized parking are endless.

2. Description of the Related Art Hitherto, there have been proposed means for preventing illegal use in parking lots of public facilities, parking reservations and the like. Patent Literature 1 proposes an annoying parking prevention device (parking reservation display device) which is installed in a parking lot for a specific reservation person and prevents a parking act by a person other than the specific user of this parking space. This nuisance parking prevention device has a warehousing prevention flap that is rotatable between a warehousing prohibited position (vertical standing posture) and a warehousing possible position (horizontal lying posture), and attempts to prevent illegal parking.

Further, Patent Document 2 proposes an entrance/exit detection device which is buried in the ground of a vehicle compartment of a parking lot. This warehousing/discharging detection device has an indicator controlled based on the information on the presence/absence of a reservation received from the reservation management device, and this indicator is a parking reservation display device for displaying the presence/absence of a reservation for a passenger compartment to be reserved. ..

The warehousing prevention flap, which is the reservation display unit described in Patent Document 1, has a flap member and a drive unit that rotationally drives the flap member. The flap member has a display section for displaying that it is exclusively for a specific reservation person, and a soft material that is elastically deformable when a vehicle comes into contact is used for the display section. However, even if the flap member is made of a flexible material, since it is the storage preventing means, the flap material may be deformed when it comes into contact with the vehicle, so damage to both the vehicle and the flap member is unavoidable. There are challenges. There is also a problem that the flap member may not be sufficiently visible to the reservation person when moving forward or backward or depending on the environment of the parking lot. Since such a storage prevention flap has a structure in which the flap member is vertically erected by rotation, it is difficult to realize a sufficiently visible size with an inexpensive structure, and it is difficult for a reservation person to enlarge the flap member. There is also a problem that it gives an intimidating feeling and damage to both the vehicle and the flap member is inevitable.

The warehousing/discharging detection device described in Patent Document 2 displays the presence/absence of a reservation by an indicator buried in the ground and does not contact a vehicle, but a warehousing for blocking parking of a vehicle not reserved. It is difficult to fully perform the blocking function.

Therefore, the present invention has been made to solve such a problem, and minimizes the damage to the vehicle and the parking reservation display device when the vehicle is stored, while improving the visibility without giving an intimidating feeling to the reservation person. A parking reservation display device that limits the number of times and provides an alternative parking area by detecting illegal parking when illegal parking is performed, and that can be operated effectively without leaving the parking lot empty. It is the one we are trying to provide.

[1] A parking reservation display device of the present invention is a parking reservation display device that is installed in an arbitrary parking section of a parking lot and displays whether or not the parking section is reserved, and the parking section is reserved. And a display unit that displays whether or not the display unit held by the support unit is vertically erected by rotating a support unit that is rotatably attached to a base unit for fixing the parking section. And a horizontal fall posture, a drive device for switching between the vertical posture posture and the horizontal fall posture, and a controller for determining whether the display unit is in the vertical posture posture or the horizontal posture, and whether the determined posture is a reserved posture. And a communication device for exchanging information between the control device and the parking reservation device. The detection device is a vehicle when the display unit is in a vertical standing posture. Has an external force detector for detecting that an external force is applied by contacting the display unit.

According to the parking reservation display device of the present invention, the display section is vertically erected to indicate that the parking section is reserved, and the display section is horizontally folded to display that the parking section is not reserved. .. The reservation person can recognize that the reserved parking section is ready for warehousing by horizontally lying down from the vertical standing state indicating that the display section is reserved. When the reservation person notifies the parking lot reservation device that the reserved parking section has been reached, the display unit can be switched from the vertical standing posture to the horizontal laid posture by the driving device to enable parking. On the other hand, when a non-reserved person invades (so-called illegal parking) regardless of the vertical standing posture and touches the display unit, and the external force detector detects that external force is applied to the display unit, it is regarded as illegal parking and is immediately driven. The device switches the display to a horizontal lying position. Information about the states of the drive device, the control device, and the detection device, that is, the state of the display unit is notified to the parking lot reservation device via the communication device. When there is illegal parking, the parking lot reservation device searches for a reservable parking section and vertically stands up the display part of the parking reservation display device installed in the parking section to display the reserved display. It will be possible.

By doing this, while increasing the visibility without intimidating the reservation person, the damage to the vehicle and the parking reservation display device at the time of warehousing is minimized, and when illegal parking is performed. It is possible to detect an illegal parking and provide an alternative parking section, and to operate the parking section effectively without leaving it empty.

[2] In the parking reservation display device of the present invention, the parking lot has a payment machine, and the display unit is arranged immediately before the scheduled date and time when the parking lot is arranged in the parking section of the coin parking and reserved by the payment machine. Is preferably controlled so as to stand upright.

Here, the reservation function is a function of vertically standing up the display unit when the reservation information is input to display that the parking section has been reserved, and the payment machine is a parking lot reservation device having a payment function and a communication function. Equivalent to. This makes it possible to easily install the parking reservation display device in a normal coin parking without a reservation function. For example, when the settlement machine accepts a reservation, the display unit is vertically erected before the scheduled time and date, and is placed in a horizontal laid posture immediately before the warehousing so that the warehousing is possible. Then, the parking fee can be settled and the reservation can be made at the time of leaving.

[3] In the parking reservation display device of the present invention, the parking lot is a free parking lot that does not collect a parking fee, and the parking lot is connected to a portable remote control terminal held by a reservation person. A reservation management device that can communicate with is installed, and the reservation management device is arranged in a parking section of the free parking lot and operates the portable remote control terminal to display the display via the reservation management device. It is preferable to control the part to switch from the vertical standing posture to the horizontal lying posture.

A parking lot that does not mainly collect parking fees refers to facilities that can be used by general people such as public facilities and hospitals. It is possible to easily install a parking reservation display device and a reservation management device in such a parking lot. The reservation management device corresponds to a parking lot reservation device without a settlement function. Examples of the portable remote operation terminal include a remote controller. That is, the parking lot manager keeps the display portion of the reserved parking section in the vertical standing posture and lends the user a remote controller that can communicate with the reservation management device. When the reservation person arrives at the reserved parking section, he/she can operate the remote controller to switch the display unit from the vertical standing posture to the horizontal lying posture, so that the person can store the goods. It is expected that people with physical disabilities and pregnant women will be used as users, and it is desirable to provide parking spaces near the entrance of the facility building to such specific people, which is effective in securing parking spaces. .. When leaving the car, if there is a reservation, the parking lot manager puts it in a vertical standing posture. As described above, the vertical standing posture can be automatically set for the purpose of always keeping a specific compartment for a specific person.

[4] In the parking reservation display device of the present invention, it is preferable that the parking reservation display device further includes a display light-emitting floodlight that causes all or part of the display part to emit light when the display part is in a vertical standing posture. ..

The display unit itself does not have an illuminating device, but has, for example, a light guiding function and a diffusing function. The floodlight for emitting light from the display unit is, for example, an LED light. When the display unit is in the vertical upright posture, the light from the display unit light-emitter is guided to light up or blink the entire display unit, the surface or the letters, thereby improving the environment of the parking lot. Therefore, it is possible to improve the visibility. For example, when the emission colors are red and white or blue and white, it is easy to recognize even if there is a difference in color vision characteristics. Since the display unit itself has no illumination means, no wiring or the like is needed, and it can be easily replaced when it is damaged or soiled. The light emission is stopped when the display unit is in the horizontal laid posture.

[5] In the parking reservation display device of the present invention, when the external force detector receives the external force from the vehicle approaching side face when the display unit is in the vertical standing posture, the display unit cannot maintain the vertical standing posture. It is preferable that the drive device has a function of autonomously shifting the display unit to the horizontal laid posture when the position is detected.

When the vehicle enters when the display unit is in the vertical standing posture and receives an external force that makes it difficult to maintain the vertical standing posture, the external force detector inputs the information to the control device. The control device controls the drive device to switch the display unit from the vertical standing posture to the horizontal lying posture. This makes it possible to minimize damage to both the vehicle and the parking reservation display device.

[6] In the parking reservation display device of the present invention, in the communication device, the display unit is in either the horizontal laid posture or the vertical standing posture based on the driving state of the drive device and the result detected by the detection device. It is preferable to notify the parking lot reservation device whether or not the user is in the posture.

As described above, the drive device drives the display unit from the vertical standing posture to the horizontal lying posture and from the horizontal lying posture to the vertical standing posture. The control device determines whether the posture is the vertical standing posture or the horizontal lying posture. The detection device detects whether the display unit is in the reserved posture or whether the display unit receives an external force. The communication device notifies the parking lot reservation device of the drive state of the drive device, the result determined by the control device, and the result detected by the detection device. This makes it possible to appropriately control the attitude of the display unit. The parking lot reservation device corresponds to a settlement machine in the coin parking, and corresponds to the reservation management device in the free parking lot.

[7] In the parking reservation display device of the present invention, the display section is formed of a flexible elastic body, and can be printed or engraved on the surface to reflect, guide or diffuse light. It is preferably formed of a material capable of being formed.

Such a display unit is made of resin and can display, for example, a character or a symbol such as "reserved", and can emit a character or a symbol, emit light around the character or the symbol, or The visibility can be further improved by causing a part or the whole of the display portion to emit light. It is also possible to emit light in various colors.

[8] In the parking reservation display device of the present invention, the display section includes a light-diffusing insertion section that is inserted into the support section, and a light-emitting section formed of an optical fiber having flexibility and elasticity. It is preferable that the front end of the light emitting portion is inserted into the insertion portion.

The flexible optical fiber can be formed into a free shape such as a curved line, and the light with which the insertion portion is irradiated can be efficiently emitted as a whole. For example, blinking red, green, or yellow can be sufficiently recognized. Further, the optical fiber has elasticity, and even if an external force is applied, the optical fiber returns to its original shape within the elastic region.

[9] In the parking reservation display device of the present invention, the external force detector has an oblique detection mechanism that detects that the display unit receives an external force in a direction other than a direction perpendicular to the vehicle entrance side surface. Preferably.

The vehicle may enter the parking compartment while driving in reverse, and an external force may be applied to the display unit from an oblique direction. Generally, in order to prevent the display unit from being damaged, it is possible to provide a mechanism such as a spring or a one-way clutch to avoid the movement in the horizontal laying direction.
However, with such a mechanism, it is difficult to prevent the component force in the thrust direction (longitudinal direction of the rotating shaft) when a force is applied from a biased position of the display unit or from an oblique direction. Therefore, it is possible to prevent the display unit from being damaged by detecting a force pushed from an eccentric position or an oblique direction, that is, a component force in the thrust direction by the oblique detection mechanism and rotating it in the horizontal fall direction. As the diagonal detection mechanism, for example, a mechanical two-way switch, an electric force sensor, an optical non-contact sensor, or the like can detect the bias in the diagonal direction of the display unit.

Hereinafter, the parking reservation display device 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 27.

[Configuration of parking reservation display device 1]
FIG. 1 is a block diagram showing the overall configuration of the parking reservation display device 1. The parking reservation display device 1 includes a display unit 2 for displaying whether or not a parking section (hereinafter, referred to as a vehicle compartment for clearly indicating a place) is reserved in the parking lot, and the display unit 2 in a vertical standing posture. The drive device 3 that switches to the horizontal laid posture, the control device 4 that determines whether the display unit 2 is in the vertical standing posture or the horizontal laid posture, and the determined posture and the display unit 2 are in different postures. It has the detection device 5 which detects whether or not. The parking reservation display device 1 has a communication device 6, and the communication device 6 exchanges information between an external parking lot reservation system 7 and the control device 4. The parking reservation display device 1 has an illumination device 8 for making it easy to visually recognize the display unit 2.

The display unit 2 displays a vertical standing posture when the passenger compartment is reserved and indicates that the passenger compartment has been reserved, and the posture is controlled by the control device 3 so as to be a horizontal laid posture when the passenger compartment is not reserved. .. The drive device 3 drives the motor 9 in accordance with the instruction from the control device 4. Motor 9 switches the display unit 2 in a predetermined posture. The control device 3 is a device that controls the entire parking reservation display device 1, and controls the drive of the drive device 3, the light emission control of the lighting device 8, the control of the detection device 5, and the attitude of the display unit 2 based on the detection result. And a function of controlling the exchange of information with the parking lot reservation system 7 by the communication device 6. The detection device 5 includes a vertical upright detector 10 that detects that the display unit 2 is in a vertical upright posture, and an external force detector 11 that detects that an external force is applied to the display unit 2. .. As a communication means between the communication device 6 and the parking lot reservation system 7, there are a dedicated wired line and an internet line, for example, a mobile phone network, Wi-Fi, BlueTooth (registered trademark) and a dedicated remote controller.

The parking lot reservation system 7 exchanges reservation applications and reservation information with the parking lot reservation person 30 using various communication means. As a reservation method by the reservation person 30, there are a reservation via an operator by telephone, a reservation through a push line response by telephone, a reservation through the Internet by a PC or a Web through a smartphone, and the like.

FIG. 2 is an external perspective view showing an example of the parking reservation display device 1. The parking reservation display device 1 has the base 12 fixed to the ground of the vehicle compartment by a fixing means such as a bolt. The lower end of the display unit 2 is attached to the base 12 via a support 35 (see FIG. 17). The state of the display unit 2 shown in FIG. 2 is referred to as a vertical standing posture, and the state indicated by a two-dot chain line is referred to as a horizontal laid posture. In the horizontal lying posture, the display unit 2 is stored in the upper surface side recess 13 of the base 12.

In the example shown in FIG. 2, the character "reserved" is printed or stamped on the vehicle entrance side surface 2a of the display unit 2. However, it is not particularly limited as long as it is possible to visually confirm that the reservation is made by a mark or an outer shape other than the character. In addition, the display unit 2 can be made more visible by emitting light or blinking. Alternatively, it is also possible to adopt a form in which the reservation person 30 is notified by vibrating when the vehicle contacts.

[Application example of parking reservation display device 1]
FIG. 3 is a diagram showing an example of a general coin parking 15 having no reservation function. Such a coin parking 15 includes a checkout machine 16 arranged at a corner of a parking lot, a wheel stop 18 arranged at an end of a vehicle compartment 17 which is a parking compartment in a traveling direction, and a wheel stopper 18, which defines a stop position of the vehicle, It has a vehicle sensor 19 which is disposed below the vehicle and detects the presence or absence of a vehicle, and a lock plate 20 which prevents unauthorized warehousing. Here, the illegal warehousing refers to warehousing without paying. Since the structure of a general coin parking 15 is well known, detailed description thereof will be omitted. The installation of the parking reservation display device 1 in the coin parking 15 will be described with reference to FIG.

FIG. 4 is a perspective view showing an example in which the parking reservation display device 1 is applied to a general coin parking 15. The same components as those in FIG. 3 are designated by the same reference numerals as those in FIG. The parking reservation display device 1 is arranged at an intermediate position between the two wheel stoppers 18 in the vehicle compartment 17 at a position where it is easily visible and at a position where there is no hindrance to the storage of the vehicle. A reservation function (function of inputting reservation information to the parking reservation display device 1) included in the parking reservation system 1 is added to the settlement machine 16. Therefore, the settlement machine 16 is a parking lot reservation device having a coin parking function and a vehicle room reservation function. The coin parking function includes a vehicle entry/exit management function, a settlement function, and a lock plate control function. The settlement machine 16 accepts a reservation from the reservation person 30, selects an empty vehicle compartment 17, and notifies the reservation person 30 of reservation information. Then, the display unit 2 is switched to the vertical standing posture immediately before the reserved scheduled date and time.

The lock plate 20 is driven to a position where the leaving is prohibited when the warehousing (parking) is completed. That is, even if the parking reservation display device 1 is installed, the parking reservation display device 1 can be used in the same manner as a conventional coin parking, and if the electric power is down, the lock plate 20 is released and it can be operated and used as a general parking lot. is there. In the case where the lock plate 20 is already installed or is installed at the same time, the lock plate 20 is controlled as a child device of the settlement machine 16 or the parking reservation display device 1 so that the reservation function can be added. Is preferred.

FIG. 5 is a perspective view showing an example of a free parking lot 25 such as a public facility. In the free parking lot 25, only the wheel stoppers 18 are arranged in the passenger compartment 17 so that anyone can park freely. However, in public facilities, hospitals, etc., it is required that a specific reservation person such as a physically handicapped person, a pregnant woman or an elderly person is provided with a parking section (vehicle compartment) closest to the entrance of the facility building. Therefore, installation of the parking lot reservation display device 1 in the free parking lot 25 including such an individual parking lot will be described with reference to FIG.

FIG. 6 is a perspective view showing an example in which the parking reservation display device 1 is applied to a free parking lot 25 such as a public facility. The parking reservation display device 1 is arranged at an intermediate position between the two wheel stoppers 18 in the vehicle compartment 17 (vehicle compartments 17a and 17b), which is easily visible, and which does not hinder the parking of the vehicle. A remote controller 26 (see FIG. 8) as a portable remote control terminal is lent to the reservation person 30 (see FIG. 7) from the parking lot manager. In the free parking lot 25, a reservation management device 27 is arranged as a parking lot reservation device for exchanging information such as reservation information and reservation cancellation with the remote controller 26. It is preferable to keep the reservation state at all times for a specific person who constantly uses it. When there are a plurality of vehicle compartments 17 that can be reserved, it is not always necessary to associate the vehicle compartment 17 with the reservation person 30. For example, when there are two vehicle compartments 17a and 17b as shown in FIG. 6, the reservation person 30 who arrives first can set one of the vehicle compartments 17a and 17b by the reservation management device 27. ..

[Operation of parking reservation display device 1]
FIG. 7 is a perspective view schematically showing a method of reserving the passenger compartment 17 in the coin parking 15 shown in FIG. FIG. 7 shows an example in which the reservation person 30 reserves the vehicle compartment 17 by the parking reservation system 7 in the cloud environment using the smartphone 31 as the reservation communication means. First, the reservation person 30 accesses the parking lot reservation system 7 from the smartphone 31 to search for a nearby parking lot at a target location, and designates the date and time at which he/she wants to make a reservation. At this time, the parking lot that cannot be reserved cannot be reserved because it is not displayed on the smartphone 31. Alternatively, it is possible to reply from the parking lot reservation system 7 to the smartphone 31 that parking is not possible. The parking lot reservation system 7 vertically stands up the display unit 2 of the parking reservation display device 1 via the settlement machine 16 immediately before the designated date and time to complete the reservation. The parking lot reservation system 7 recognizes that the reservation target vehicle compartment 17 has been reserved by being notified by the detection device 5 via the adjustment machine 16 that the display unit 2 has been detected to stand upright. The lock plate 20 is in a state in which the vehicle can be stored.

In addition, when the vehicle is already parked in the reserved vehicle compartment 17 and has not been delivered by the designated date and time, the parking lot reservation system 7 searches for an empty vehicle compartment in the same parking lot and can park the vehicle. Is reserved and the information is transmitted to the smartphone 31. When there is no vacant car room in the same parking lot and the reservation cannot be made, the parking lot reservation system 7 searches for a vacant car room in a nearby parking lot, makes a reservation, and transmits the fact to the smartphone 31. As the reservation communication means, a personal computer, a tablet terminal or the like can be applied in addition to the smartphone 31. The communication means 32 between the parking lot reservation system 7 and the settlement machine 16 may be wired (telephone line, dedicated data line, etc.) or wireless (cellular phone network, Wi-Fi, etc.).

FIG. 8 is an explanatory diagram schematically showing a method of canceling the reservation of the passenger compartment 17 in the free parking lot 25 such as the public facilities shown in FIG. FIG. 8 shows an example in which the reservation person 30 cancels the reservation of the passenger compartment 17 via the reservation management device 27 by the remote controller 26 as the reservation communication means. The reservation person 30 reserves the vehicle room 17 to be parked in advance by telephone, smartphone, internet or the like. In the parking reservation display device 1, the parking lot manager manually stands the display unit 2 vertically. Alternatively, the parking reservation display device 1 is driven by the reservation management device 27 to vertically erect the display unit 2. The reservation person 30 operates the remote controller 26 to bring the display unit 2 to the horizontal laid posture when the vehicle compartment 17 desired to park is approached, and enters the reserved vehicle compartment. A specific person, such as a person with a physical disability, operates the remote controller 26 to switch the display unit 2 to the horizontal lying posture even when the passenger compartment 17 that can be used preferentially is constantly in the reserved state.

FIG. 9 shows an example in which, in the coin parking 15 shown in FIGS. 6 and 7, a reservation person 30 whose reserved passenger compartment 17 is unknown arrives at the coin parking 15 and inquires of the reserved passenger compartment to the parking reservation system 7. FIG. The reservation person 30 informs the parking lot reservation system 7 of the arrival at the entrance of the coin parking 15 or an empty space near an unspecified vehicle compartment with the smartphone 31. Then, the number of the reserved vehicle compartment 17 is notified from the parking lot reservation system 7 to the smartphone 31.

FIG. 10 is an explanatory diagram showing that the reservation person 30 notifies the parking lot reservation system 7 that the reserved passenger compartment 17 is known in the coin parking 15. The reservation person 30 notifies from the smartphone 31 that he/she arrived at the parking lot reservation system 7 when he came just before the reserved vehicle compartment 17. The parking lot reservation system 7 switches the display unit 2 of the parking reservation system 1 to the horizontal lying posture via the settlement machine 16. Thereby, the reservation person 30 can recognize that the warehousing has become possible.

FIG. 11 is an explanatory diagram showing that the reservation person 30 has completed parking (stocking) in the coin parking 15. Immediately before entering the warehouse, the display unit 2 is in a horizontal laid posture. Note that after entering the warehouse, the vehicle sensor 19 detects the vehicle at a predetermined position and inputs it to the settlement machine 16 as in a general coin parking. In response to a command from the settlement machine 16, the lock plate 20 is raised to regulate the warehousing. In the case of a lock plate-less parking lot without the lock plate 20, it may be possible to monitor the exit from a sensor or a camera. At the time of leaving the warehouse, if the parking fee is settled by the settlement machine 16, the lock plate 20 is released and the state is ready for leaving. When the delivery is completed, the vehicle sensor 19 detects that the vehicle is not in the vehicle compartment 17, and inputs the fact that the vehicle can be reserved to the parking lot reservation system 7 via the settlement machine 16. Note that, instead of the payment of the parking charge by the payment machine 16, the cashless payment function of the smartphone 31 can be used while the passenger is still on the board, and points can be given.

FIG. 12 is an explanatory diagram showing an example in which the original reservation person 30 arrives at the passenger compartment 21 in which a vehicle not reserved is parked and notifies the settlement machine 16. Note that FIG. 12 shows an example of the coin parking 15. When the reserved vehicle compartment is not known, the reservation person 30 notifies the smartphone 31 of arrival at the parking lot reservation system 7 at the entrance of the coin parking 15 or an empty space near an unspecified vehicle compartment. If the reservation person 30 does not know the reserved vehicle room in advance (a system that does not notify the reserved vehicle room), the parking lot reservation system 7 automatically makes an alternative reservation for the vehicle room 22 that can be replaced when the illegal parking is confirmed. The person who reserves the vehicle can park it as if the passenger compartment 22 had been reserved from the beginning without being aware of illegal parking. If the reservation person knows the reserved vehicle room in advance (a system that reserves a unique vehicle room), the non-reserved person 23 has already parked in the vacant vehicle room 21, so the reserved person 30 The parking lot reservation system 7 will inquire about the vehicle compartment for confirmation. This inquiry is a notification of so-called illegal parking, but since the parking lot reservation system 7 has already secured an alternative vehicle compartment, it is not important enough to be illegal. Naturally, such a state has already been incorporated in the parking lot reservation system, so it is convenient to use a system that notifies the reservation person 30 in advance that the reserved vehicle room has been changed when illegal parking is confirmed. Above desirable. Then, the parking lot reservation system 7 notifies the number of the reserved passenger compartment 21. The reservation person 30 who confirms that the non-reservation person 23 is parked in the vehicle compartment 21 notifies the parking lot reservation system 7 of illegal parking using the smartphone 31. Then, the parking lot reservation system 7 guides the alternative passenger compartment 22 to the reservation person 30 as a new reserved compartment. If there is no vacant car room in the same parking lot, the vacant car room in the nearby parking lot is notified to the reservation person.

The guidance of the alternative vehicle compartment and the alternative parking lot is automatically provided by the parking lot reservation system 7 at the stage when the illegal parking is confirmed without the notification from the reservation person 30. If the reservation is changed to a nearby parking lot, the reservation person 30 will be notified before arriving at the original parking lot. The contact time will be earlier than that, because the time of the initial reservation, that is, the time when parking will start, is known in advance. In addition, since the non-reserved person 23 who has illegally parked may leave the vehicle earlier than the reserved time or the reserved person may be behind the reserved time, the substitute reserved vehicle room 22 should be restored to the vehicle room 21. Is also possible. Further, if AI or the like is applied, it becomes possible to notify the reservation person 30 at the optimum time by calculating from the distance and traffic jam information of the initially reserved parking lot and the substitute reserved neighboring parking lot.

FIG. 13 is an explanatory diagram showing an example in which the reservation of the vehicle compartment 21 is canceled and the reservation person enters the reserved vehicle compartment 22. Note that FIG. 13 shows an example of the coin parking 15. In the passenger compartment 21 in which the non-reserved person 23 has entered, the display unit 2 is in a horizontal lying posture, and the vehicle sensor 19 detects that the vehicle has entered. The parking reservation display device 1 determines whether the display unit 2 is in the vertical standing posture or the horizontal lying posture, and notifies the reservation person 30 of the substitute vehicle compartment 22 via the smartphone 31. In the passenger compartment 22, the reservation person 30 can know that the display unit 2 can be parked by lying down from the vertical standing state.

FIG. 14 is an explanatory diagram showing an example in which the reservation person 30 completes parking in the substitute vehicle compartment 22. Immediately before the reservation person 30 enters the warehouse, the display unit 2 is in a horizontal lying posture. It should be noted that, like the general coin parking after the warehousing, the display unit 2 is in the horizontal laid-down posture, and when the warehousing is completed, the vehicle sensor 19 detects the vehicle and the lock plate 20 is lifted by a command from the settlement machine 16. Regulate shipping. When leaving the warehouse, the lock plate 20 is released when the parking fee is settled by the settlement machine 16, and the warehouse can be delivered. When the leaving of the vehicle is completed, the vehicle sensor 19 detects that the vehicle is not in the passenger compartment 22 and notifies the parking lot reservation system 7 via the settlement machine 16 that the vehicle can be reserved. Note that the non-reserved person 23 can unlock the lock plate 20 and exit when the parking fee is settled by the settlement machine 16, as in ordinary coin parking. However, it is possible to separately request an additional fee due to illegal parking. When the non-reserved person 23 leaves the vehicle, the vehicle sensor 19 detects that the vehicle has exited and notifies the parking reservation display device 1 that the parking reservation display device 1 is reset and the passenger compartment 21 becomes ready for reservation.

FIG. 15 is an explanatory diagram showing an example in which the display unit 2 is horizontally laid down and stored by the remote controller 26. The example shown in FIG. 15 shows an example of storage when the reservation management device 27 is installed in the free parking lot 25 such as a public facility. The reservation person 30 has reserved the passenger compartment 17 in which he/she wants to park in advance by telephone or the internet. The reservation manager directly operates the reservation management device or vertically stands up the display unit 2 with a remote controller dedicated to the reservation manager. The reservation person 30 operates the remote controller 26 to bring the display unit 2 into the horizontal lying posture via the reservation management device 27 when the vehicle reaches the immediate vicinity of the passenger compartment 17 to be parked. The reservation person 30 confirms that the display unit 2 is in the horizontal lying posture, and then enters the vehicle compartment 17. Even when the passenger compartment 17 that can be used preferentially for persons with physical disabilities is constantly reserved, the remote controller 26 is operated to switch the display unit 2 to the horizontal lying posture and the goods are stored. At the time of leaving the warehouse, the fact that the warehouse has been delivered by the remote controller 26 is input to the reservation management device 27, and the state is changed to a rebookable state (vertical standing posture).

FIG. 16 is a perspective view schematically showing a state in which it is detected that the vehicle is in contact and the display unit 2 receives an external force. The display unit 2 receives an external force when the vehicle contacts. The display unit 2 tilts as illustrated by such an external force. Although not shown, the display unit 2 is rotatably attached to the base 12 at the base via the support 35 (see FIG. 17). Although details will be described later with reference to FIG. 17, a sensor that detects an external force is arranged at a connecting portion between the support portion 35 and the display portion 2. The sensor is a transmissive photoelectric sensor 37 (see FIG. 17). The transmissive photoelectric sensor 37 detects light transmission when the display unit 2 is in a vertical standing posture and shields light when the display unit 2 is tilted. Detect that. That is, the control device 4 detects that an external force acts on the display unit 2 due to the light blocking. When it is detected that an external force is applied, the control device 4 inputs a drive command to the drive device 3 so as to bring the display unit 2 into the horizontal laid posture, and the display unit 2 is switched to the horizontal laid posture.

As the transmissive photoelectric sensor 37, a reflective photoelectric sensor or a regression photoelectric sensor can be used, and in addition, a non-contact switch such as a proximity switch or a contact sensor such as a mechanical switch can also be applied.

FIG. 17 is a perspective view schematically showing an example in which the display unit 2 is vertically erected, horizontally laid down, a mechanism for detecting an external force, and the display unit 2 is caused to emit light. The display unit 2 is tilted about the rotation axis center 36 by an external force. The transmissive photoelectric sensor 37 for detecting an external force has a light emitting element 38 and a light receiving element 39, and the sensor optical axis 40 is arranged apart from the display unit 2 in the direction in which the display unit 2 falls. Therefore, in the vertical standing posture in which no external force is applied, the light receiving element 39 detects the light from the light emitting element 38 to detect that no external force is applied by the external force detector 11 (see FIG. 1). When an external force is applied to the display unit 2 and the display unit 2 tilts, the sensor optical axis 40 is blocked by the display unit 2 and shielded. Then, the external force detector 11 determines that an external force that cannot maintain the vertical standing posture is applied and switches the display unit 2 to the horizontal lying posture by the driving device 3 (see FIG. 1). This makes it possible to minimize damage to both the vehicle and the parking reservation display device 1. The external force detector 11 detects light transmission or light shielding by the transmission photoelectric sensor 37.

Note that the vehicle may enter the vehicle interior while turning back and forth, and external force may be applied obliquely to the display unit 2. In such a case, it is preferable to provide an oblique detection mechanism. Although illustration is omitted, for example, a reflection type photoelectric sensor or a regression type photoelectric sensor can be used as the diagonal detection mechanism, and in addition, a non-contact switch such as a proximity switch or a contact sensor such as a mechanical switch is also applied. It is possible. The external force pushed from the diagonal direction, that is, the component force in the thrust direction is detected by the diagonal detection mechanism and rotated by the motor 9 in the horizontal fall direction, whereby the damage can be prevented.

On one side end face side of the display unit 2, a display unit light emitting projector 41 is arranged. When the display unit 2 is in the vertical standing posture, the light emitted from the display unit light emitting projector 41 is applied to the end face of the display unit 2, and the whole or a part of the display unit emits light due to the light guiding function and the diffusion function of the display unit 2. To do. When the display unit 2 is tilted by receiving an external force, the optical axis 42 of the display unit light emitting projector 41 is deviated from the display unit 2. Therefore, the display unit 2 emits light only in the vertical standing posture, and informs the reservation person 30 of the reserved location of the vehicle compartment 17. Note that the display unit light-emitter 41 may be arranged on both sides of the end surface of the display unit 2, or the light emission color may be changed or blinked to further enhance the visibility. In addition, a pipe-shaped or rod-shaped light guide may be arranged around the display unit 2 so that light is incident from the display unit light emitting projector 41 to emit light.

FIG. 18 is an explanatory diagram schematically showing an example of a mechanism for connecting the display unit 2 and the support unit 35 and a mechanism for detecting an external force. In the display unit 2, a lower end portion of the insertion portion 55 shown on the lower side of the drawing is a convex portion 43 having a substantially semicircular shape, and a spring fitting provided on the rear surface 2b side with respect to the vehicle entrance side surface 2a and formed in a conical shape. And a joint portion 44 (see FIG. 22 for details). The center of the semicircle of the convex portion 43 is defined as the central axis 43a. The insertion portion 55 is inserted into the space 49 of the support portion. On the other hand, in the support portion 35, the display portion fixing springs 45, 45 are arranged at positions facing the spring fitting portion 44, and are provided on the lower side in the figure for fitting the convex portion 43 of the display portion 2 to fit therein. A substantially semicircular concave portion 46, a light transmitting hole 47 through which the sensor optical axis 40 passes, and a light projecting hole 48 through which the light emitted from the display section light projecting projector 41 passes are formed. In the display unit 2, the root portion is inserted into the space 49 of the support portion 35, and the convex portion 43 fits into the concave portion 46. The center of the semicircle of the convex portion is the central axis 46a.

FIG. 19 is a perspective view showing an example when the display unit 2 is not receiving an external force. When the display unit 2 is in the vertical standing posture, the convex portion 43 of the display unit 2 fits into the concave portion 46 of the support unit 35 and is pressed by the display unit fixing spring 45 to form a loose elastic connection. That is, when an external force is applied to the upper side of the display unit 2 from the vehicle entrance side surface 2a side, the display unit 2 is easily tilted around the axis 50. The shaft 50 becomes as if it were the center of the rotation axis when the projection 43 of the display unit 2 slips when the display unit 2 is mounted on the support unit 35. When the display unit 2 is in the vertical standing posture, the sensor optical axis 40 is located at a position separated from the back surface 2b of the display unit 2, and the external force detector 11 determines that no external force is applied to the display unit 2. The optical axis 42 of the projector 41 for illuminating the display emits light to the display 2 toward the side end surface of the display 2. The display unit fixing spring 45 maintains the upright posture of the display unit 2.

FIG. 20 is a perspective view schematically showing an example in which the display unit 2 receives an external force F even in the center in the width direction or left and right. When the display unit 2 receives an external force F left and right evenly with respect to the central portion of the vehicle entrance side surface 2a or the vehicle entrance direction, the two display unit fixing springs 45 bend substantially evenly on the left and right, and the display unit 2 is centered on the shaft 50. And tilt in the direction of the arrow shown. The sensor optical axis 40 is blocked by the display unit 2, and the external force detector 11 detects that the external force F is applied to the display unit 2 and drives the drive unit 3 (see FIG. 1) via the control unit 4 to display Switch the part 2 to the horizontal lying position. Since the optical axis 42 of the projector light emitting projector 41 is in the range of the side end face of the display unit 2, it emits light although the brightness is reduced. If the external force F is released before the driving device 3 starts driving, the display unit 2 returns to the vertical standing posture by the elastic force of the display unit fixing spring 45. The external force applied to the display unit 2 is not limited to the center in the width direction or the left and right. This will be described with reference to FIG.

FIG. 21 is a diagram schematically illustrating the movement of the display unit 2 when an external force F is applied from a position biased with respect to the vehicle entrance side surface 2a of the display unit 2 or from an oblique direction. FIG. 21A is a diagram showing an example of the direction and position of the external force applied to the display unit 2. The upper diagram is a plan view seen from above, and the lower diagram is seen from the vehicle entrance side 2a side. It is a front view. FIG. 21A illustrates a case where an external force F is applied to the right side of the vehicle approach side surface 2a in the figure. The external force F also includes an external force from the left and right diagonal directions with respect to the vehicle approach side surface 2a. When the external force F is applied to the display unit 2, FIG. 21B is a diagram showing the movement of the display unit when the external force F is applied. The upper diagram is a plan view seen from above, and the lower diagram is shown. [Fig. 4] is a front view seen from the vehicle entrance side surface 2a side. When the external force F is applied, the right display part fixing spring 45 is mainly compressed and rotates counterclockwise. Along with this movement, the display unit 2 rotates counterclockwise around the left edge of the support unit 35 while the right side of the convex portion 43 of the display unit 2 rides on the tangent line 51 or the straight line 52 (see FIG. 22). To lean. At this time, the spring fitting portion 44 deviates from the display portion fixing springs 45, 45. The display unit fixing springs 45, 45 will be described with reference to FIG. As shown in FIG. 21B, when viewed from above, when the back surface 2b of the display unit 2 blocks the sensor optical axis 40, the optical photoelectric sensor 37 detects that the external force F is received. Since the display unit 2 has flexibility, it rotates and tilts while being bent when an external force F is applied. Although detailed description is omitted, the display unit 2 rotates and tilts similarly to the right side even when an external force F is applied from the left side of the display unit 2, although the rotation direction and the tilt direction are different.

FIG. 22 is an enlarged schematic perspective view of the support portion 35 when the detection degree of the external force received by the display portion 2 is changed. Note that FIG. 21 shows an example in which the shape of the convex portion 43 of the display unit 2 is constant. The contact area when the convex portion 43 of the supporting portion 35 and the concave portion 46 of the supporting portion 35 are fitted together determines the degree of the external force. As shown in FIG. 21, if the tangential line 51 of the arc of the concave portion 46 is extended, the contact area of the convex portion 43 becomes small and the display unit 2 tilts with a weak external force. If a straight line 52 that expands the arc range of the recess is formed so as to intersect the arc, the contact area becomes large, and the display unit 2 is inclined with a stronger external force than when it is formed by the tangent line 51. As a method for adjusting the strength of the external force for inclining the display unit 2, for example, a filled spacer 53 is added based on the shape having the tangent line 51 shown in FIG. 21, or the display unit 2 is partially supported. It is possible to have a shape or to provide a local support portion that is connected by fine unevenness. Alternatively, by increasing or decreasing the frictional force by interposing a sheet having a different friction coefficient between the convex portion 43 and the concave portion 46, the degree of detection of the external force, that is, when switching from the vertical standing posture to the horizontal lying posture. The magnitude of the external force detected can be changed.

FIG. 23 is a sectional view schematically showing a structure for maintaining the vertical standing posture of the display unit 2. The display unit 2 is inserted into the space 49 of the support unit 35, and the protrusion 43 of the display unit 2 fits into the recess 46 of the support unit 35. The display unit 2 is pressed by the side wall portion 35a of the support unit 35 on the vehicle entry side surface 2a side by the display unit fixing spring 45 to be in a vertical standing posture. The display portion fixing spring 45 has the tail portion inserted in the side wall portion 35b on the back surface 2b side of the support portion 35. The tip portion 45 a of the display fixing spring 45 has a conical shape that follows the conical shape of the spring fitting portion 44, and fits into the spring fitting portion 44. Therefore, the position of the display unit 2 in the vertical and horizontal directions is defined on the support unit 35 by the display unit fixing springs 45, 45. However, since the display unit 2 is only inserted into the support unit 35, it can be easily attached to or removed from the support unit 35. When an external force is applied to the vehicle entrance side surface 2a, the display unit fixing spring 45 bends and can be inclined to a position detected by the external force detector 11.

The approaching direction of the vehicle, the direction in which the display unit 2 changes from the vertical standing posture to the horizontal lying posture, and the attaching/detaching direction with respect to the support unit 35 coincide with each other. When the display unit 2 receives the external force F from the vehicle, the display unit 2 begins to fall horizontally, and further continues to receive the external force F, the display unit 2 further tilts, and the display unit 2 may depend on the speed at which the external force is applied. It becomes possible to escape the damage by falling off the supporting portion 35 beyond the pressing force. Since the tip end portions 45a of the display portion fixing springs 45, 45 have a conical shape that follows the conical shape of the spring fitting portion 44, the fitting is disengaged when an external force F larger than expected is applied. Moreover, the function can be restored simply by inserting the display unit 2. The display unit fixing springs 45, 45 have a sparse winding structure so that the display unit 2 can withstand the forces in both the radial direction and the thrust direction and can be disengaged from the support unit 35 when a large external force F is applied. There is. Further, the width of the space 49 of the support portion 35 is longer than the width of the display portion 2 and there is a gap in the left-right direction (the width direction of the display portion 2), so that the display portion fixing springs 45, 45 have a conical shape. The tip can position the display unit 2 with respect to the support unit 35.

FIG. 24 is a cross-sectional view showing a method of inserting the display unit 2 into the support unit 35. First, as shown in FIG. 24A, the L-shaped insertion jig 54 is inserted from above between the display fixing springs 45, 45 and the side wall 35 a of the support 35. Subsequently, as shown in FIG. 24B, the insertion jig 54 is moved to the right to bend the display fixing springs 45, 45, and the display portion 2 is provided between the insertion jig 54 and the side wall portion 35a. Is inserted, and the insertion jig 54 is pulled out upward. After pulling out the insertion jig 54 and fitting the tip end portions 45a of the display fixing springs 45, 45 to the spring fitting portion 44 of the display portion 2, the display portion 2 is supported in the state as shown in FIG. It can be attached to 35.

In addition, although the plate-shaped display unit 2 is illustrated and described in FIGS. 2 to 23, a display unit 2F using an optical fiber can be adopted, and a configuration of such a display unit 2F is illustrated in FIG. Will be described.

FIG. 25 is a perspective view showing a display unit 2F using an optical fiber. The display unit 2F includes a light-transmitting insertion portion 55 and a cable-shaped light emitting portion 56. In the example shown in FIG. 25, the light emitting portion 56 has a substantially U shape, but this shape can be arbitrarily formed. Both U-shaped tip portions of the light emitting portion 56 are inserted into the insertion portion 55. The insertion portion 55 corresponds to the insertion portion 55 (see FIG. 18) of the plate-shaped display portion 2 and is attached to the support portion 35. As the optical fiber, for example, a fiber whose core is made of a transparent acrylic resin and whose clad is made of a transparent fluororesin and has flexibility is suitable. A reserved display board 57 can be attached to the light emitting unit 56.

The optical fiber can be formed into a free shape such as a curved line, and can efficiently emit the light emitted to the insertion portion 55 to the whole. For example, even if blinking red, green, or yellow is sufficiently recognized. be able to. Like the display unit 2, the display unit 2F itself does not have an illuminating means, so wiring is not necessary, and it can be easily replaced when it is damaged or soiled. Further, in the shape example shown in FIG. 25, since the space surrounded by the light emitting portion 56 is wide, even if it has flexibility, it has sufficient wind resistance. Further, it is possible to recognize even if the light emitting portion 56 is formed into a rod shape and the light emitting end face is directed toward the vehicle approach direction, and it is possible to arrange a plurality of rod-shaped light emitting portions. Further, also in the display unit 2F, since the plate-shaped display unit 2 and the insertion unit 55 have the same structure, the external force F detection structure described in FIG. 21 can be applied.

FIG. 26 is a plan view showing an example of the driving device 3, and FIG. 27 is a front view showing the driving device 3 as seen from the front side of FIG. The drive device 1 is composed of a plurality of gears and a rotary link that connects the gears between a rotary shaft 60 that rotates the display unit 2 and a geared motor 61 that is a drive source, and a link. The rotation of the geared motor 61 is transmitted to the first gear 62, the second gear 63, and the third gear 64. The rotation of the third gear 64 is converted into a reciprocating motion by the first link 66 via the first rotation link 65. The reciprocating motion of the first link 66 is transmitted to the third rotary link 69 via the second rotary link 67 and the second link 68, and rotates the rotary shaft 60. Since the support portion 35 is axially fixed to the rotation shaft 60, the display portion 2 can be rotated from the vertical standing posture to the horizontal lying posture and from the horizontal lying posture to the vertical standing posture by switching the rotation direction of the geared motor 61. Is possible.

Note that the drive device 3 shown in FIG. 24 is an example, and for example, the rotating shaft 60 may be directly rotated by the geared motor 61, or the rotating shaft 60 may be rotated via a spur gear and a worm gear. Good.

The parking reservation display device 1 described above rotates with respect to the display unit 2 that displays whether or not the vehicle compartment 17 that is the parking compartment is reserved, and the base 12 that is fixed to the vehicle compartment 17 that is the parking compartment. A drive device 3 that rotates the support portion 35 that is movably mounted to switch the display unit 2 held by the support portion 35 between a vertical standing posture and a horizontal lying posture, and a display unit 2 that is in a vertical standing posture and a horizontal lying posture. Control device 4 that determines which of the postures the vehicle is in, a detection device 5 that detects whether the determined posture is the reserved posture, the control device 4, and the settlement machine 16 that is a parking lot reservation device. It has a communication device 6 (installed in the coin parking 15) or a reservation management device 27 (installed in the free parking lot 25) for exchanging information. The detection device 5 has an external force detector 11 that detects that the vehicle is in contact with the display unit 2 and applies an external force when the display unit 2 is in the vertical standing posture.

The parking reservation display device 1 displays that the passenger compartment 17 is reserved by vertically raising the display portion 2, and displays that the passenger compartment 17 is not reserved by horizontally lying the display portion 2. .. The reservation person 30 can recognize that the reserved parking section can be stored because the display unit 2 is horizontally laid down from the vertical standing state indicating that the reservation has been made. When the reservation person 30 notifies the settlement machine 16 or the reservation management device 27, which is the parking lot reservation device, that the reservation person 30 has reached the reserved vehicle compartment 17, the display unit 2 is switched from the vertical standing posture to the horizontal lying posture by the driving device 3. It becomes possible to park instead. On the other hand, when the non-reserved person 23 enters (illegal parking) regardless of the vertical standing posture and contacts the display unit 2 and the external force detector 11 detects that an external force is applied to the display unit 2, it is regarded as illegal parking once. Immediately, the drive device 3 switches the display unit 2 to the horizontal lying posture. Information regarding the states of the drive device 3, the control device 4, and the detection device 5, that is, the state of the display unit 2 is notified to the settlement machine 16 or the reservation management device 27 via the communication device 6. When there is illegal parking, it is possible to search for a reservable parking section and vertically stand up the display unit 2 of the parking reservation display device 1 installed in the vehicle compartment 17 to obtain a reserved display. Become. It should be noted that if the parking section that was once treated as illegal parking is a person who made a reservation in response to an inquiry from the parking lot reservation system 7, it will not be treated as illegal parking.

By doing so, damage to the vehicle and the parking reservation display device 1 at the time of storage can be minimized while enhancing visibility without giving an intimidating feeling, and if illegal parking is performed, illegal parking can be performed. By detecting that there is an alternative parking section, it becomes possible to operate effectively without leaving the parking section empty.

In the case where the parking lot is the coin parking 16 equipped with the payment machine 16, the payment machine 16 has a reservation function and is arranged in the parking section 15 of the coin parking 16 and the scheduled date and time reserved by the payment machine 16 is displayed. Immediately before this, the display is controlled to stand upright. By doing so, it becomes possible to easily install the parking reservation display device 1 in the normal coin parking 16 having no reservation function. When the settlement machine 16 to which the reservation function is added accepts the reservation, the display unit 2 is vertically erected immediately before the reserved scheduled date and time, and is placed in the horizontal laid posture immediately before the warehousing so that the warehousing is possible. Then, the parking fee can be settled and the reservation can be made at the time of leaving.

The parking lot is a free parking lot that does not collect a parking fee. In the free parking lot 25, there is a reservation management device 27 capable of communicating with a remote controller 26 which is a portable remote operation terminal held by the reservation person 30. is set up. The reservation management device 27 is arranged in the vehicle compartment 17 which is a parking compartment of the free parking lot 25, and is operated to operate the remote controller 26 to switch the display unit 2 from the vertical standing posture to the horizontal lying posture.

The parking lot manager keeps the display unit 2 of the reserved vehicle compartment 17 in a vertical standing posture, and lends a remote controller communicable to the reservation management device 27 to the user. When the reserved person 30 arrives at the reserved vehicle compartment 17, the reserved person 30 can store the vehicle by operating the remote controller 26 to switch the display unit 2 from the vertical standing posture to the horizontal lying posture. It is expected that the user will be a physically handicapped person or a pregnant woman, and it is desirable to provide a vehicle compartment near the entrance of the building of the facility to such a specific person, which is effective for securing the vehicle compartment. When leaving the warehouse, it is possible to operate the remote controller 26 to bring the display unit 2 into a horizontal laid posture capable of making a reservation. When reserving a specific section for a specific person as described above, it is desirable to have a vertical standing posture automatically or by the administrator's hand.

The parking reservation display device 1 further includes a display unit light-emitting floodlight 41 that causes all or part of the display unit 2 to emit light when the display unit 2 is in the vertical standing posture. The display unit 2 itself has a light guiding function, a diffusing function, and the like without a lighting device. When the display unit 2 is in the vertical standing posture, the light from the display unit light-emitter 41 is guided to light up or blink the entire display unit, the surface, characters, etc. It is possible to further improve the visibility regardless of. For example, when the emission colors are red and white or blue and white, it is easy to recognize even if there is a difference in color vision characteristics. Since the display unit 2 itself has no illumination means, no wiring or the like is required, and it can be easily replaced when it is damaged or soiled.

Further, when the external force detector 11 detects that the display unit 2 cannot maintain the vertical standing posture due to an external force from the vehicle approaching side surface 2a when the display unit 2 is in the vertical standing posture, the drive device 3 is detected. Has a function of autonomously shifting the display unit 2 to the horizontal lying posture. When the vehicle enters when the display unit 2 is in the vertical standing posture and receives an external force that makes it difficult to maintain the vertical standing posture, the external force detector 11 inputs the information to the control device 4. The control device 4 controls the drive device 3 to switch the display unit 2 from the vertical standing posture to the horizontal lying posture. This makes it possible to minimize damage to both the vehicle and the parking reservation display device. Since the display unit 2 is formed of an elastic body having flexibility, it not only suppresses damage but also has a time margin even if the speed at which an external force is applied is faster than the speed at which it is switched to the horizontal laid state. It is possible to further suppress damage.

In addition, the communication device 6 is a parking lot reservation device which is a parking lot reservation device that determines whether the display unit 2 is in the horizontal lying posture or the vertical standing posture based on the driving state of the driving device 3 and the result detected by the detecting device 5. 16 or the reservation management device 27 is notified.

The drive device 3 drives the display unit 2 from the vertical standing posture to the horizontal lying posture and from the horizontal lying posture to the vertical standing posture. The control device 4 determines whether the posture is the vertical standing posture or the horizontal lying posture. The detection device 5 detects whether the display unit 2 is in a reserved posture or whether the display unit 2 receives an external force. The communication device 6 notifies the driving state of the drive device 3, the result determined by the control device 4 and the result determined by the detection device 5 to the settlement machine 16 or the reservation management device 27, thereby properly adjusting the posture of the display unit. It becomes possible to control.

In addition, the display unit 2 is formed of a flexible elastic body, can be printed or inscribed on the surface, and is formed of a material capable of reflecting, guiding, or diffusing light. ..

The display unit 2 is made of resin, and can display that it is reserved, for example, by a character or symbol such as "reserved". The visibility can be further enhanced by emitting light or by causing a part or the whole of the display portion to emit light. Further, the display unit 2 configured as described above can enter the garage with a sense of security without giving an intimidating feeling to the reservation person 30.

In addition, the display unit 2F includes a light-diffusing insertion portion 55 that is inserted into the support portion 35, and a light emitting portion 56 that is formed of an optical fiber that is flexible and elastic, and the tip of the light emitting portion 56 is It is attached to the insertion portion 55. The optical fiber can be formed into a free shape such as a curved line, and the light emitted to the insertion portion 55 can be efficiently emitted to the whole. For example, blinking red, green, or yellow is sufficient. Can be recognized. Since the display unit 2F itself does not have an illumination means, no wiring or the like is required, and it can be easily replaced when it is damaged or soiled. Further, in the shape example shown in FIG. 25, since the space surrounded by the light emitting portion 56 is wide, even if it has flexibility, it has sufficient wind resistance. Further, since it is more flexible than the plate-shaped display unit 2, it has an effect of avoiding damage to the vehicle and the parking reservation display device 1.

Further, the external force detector 11 has an oblique detection mechanism (not shown) that detects that the display unit 2 receives an external force in a direction other than the direction perpendicular to the vehicle entrance side surface 2a. The vehicle may enter the passenger compartment while driving in reverse, and external force may be applied to the display unit 2 from an oblique direction. In such a case, by providing the diagonal detection mechanism, it is possible to detect external force from the diagonal direction and rotate the display unit 2 in the horizontal fall direction by the motor 9 to prevent damage.
