Description

  The present invention relates to a transmitter used in an automatic door device, and more particularly, to a transmitter used in an automatic door device that automatically opens and closes an entrance door provided at an entrance of a house or the like.

  The demand for automatic doors is increasing even in ordinary homes due to the background of aging, home nursing, and outdoor activities for physically disabled persons. Therefore, an automatic door device has been proposed in which a front door of a general house can be opened and closed remotely using a transmitter (hereinafter referred to as “remote key”). The remote key is also called a “remote control key” or a “wireless key”.

  Such a remote key has been used in the automobile field in recent years, and has the same type of configuration as a remote controller used in a keyless entry system for unlocking / locking a door of an automobile.

  Such a general remote key is a transmitter that uses a battery such as a button battery as a power source, and has an open button and a close button. When any button is pressed, a receiver (possibly integrated with an electric lock) installed near the entrance door receives the remote key signal (ie unlocking or locking signal) and the entrance door. The electric lock attached to the door is unlocked or locked, and the entrance door is opened or closed by the door driving device.

  As a communication medium between the remote key and the receiver, radio waves, near infrared rays, ultrasonic waves, and the like can be used. Among these communication media, radio waves in the several hundred MHz band are often used because of the size of the transmitting element, the point that it is not easily affected by disturbances, and the fact that the receiver does not have to be exposed outdoors. Also, the remote key is made small so that it can be easily put in a pocket. Some remote keys do not have the above open button or close button.

  Below, the prior art regarding the automatic door for general houses is demonstrated.

  For example, Patent Document 1 (Japanese Patent No. 4487458) discloses a “house door automatic opening / closing system” capable of opening a door and entering inside with complete hands-free operation. The automatic door opening and closing system for a house disclosed in Patent Document 1 includes an electronic key, authentication means, locking / unlocking means, latching means, door closer, door opening means, and control means. The electronic key always transmits unique identification information. The authentication unit receives the unique identification information transmitted from the electronic key, and collates the unique identification information with registered information stored in advance. The locking / unlocking means locks and unlocks the house door. The latch means is latched when the locking / unlocking means is unlocked, and maintains the closed state of the house door. The door closer accumulates the urging force in the door closing direction with the opening operation of the house door. The door opening means opens the housing door at a predetermined opening against the urging force of the door closer by operating. The control means is connected to the authentication means, the locking / unlocking means, the latch means, and the door opening means. While the authentication means verifies the match between the identification information and the registration information, the control means places the locking / unlocking means in the unlocked state and releases the latching state of the latching means to forcibly release the latching means. Then, the door opening means is operated to maintain the open state of the house door. When the unique identification information from the electronic key is no longer received by the authentication means, the control means releases the house door open state by the door opening means and locks the unlocking means after the door door is closed by the door closer. State.

  Patent Document 2 (Japanese Patent Application Laid-Open No. 2011-185010) discloses an “automatic door device” that opens and closes a door without operating a button on a remote controller. The automatic door device disclosed in Patent Document 2 includes a remote control and an opening / closing mechanism that automatically opens and closes the door in response to a signal from the remote control. The remote control includes a motion detection unit, a storage unit, a determination unit, and a transmission unit. The motion detection means detects the motion of the remote controller. The storage means stores the door open / close signal and the movement of the remote controller in association with each other in advance. The determining means determines which of the door opening / closing signals corresponds to the movement of the remote controller by comparing the determination result of the movement detecting means with the stored contents of the storage means. The transmission means transmits the determination result of the determination means to the opening / closing mechanism.

  Furthermore, Patent Document 3 (Japanese Patent Application Laid-Open No. 2002-285756) discloses a remote control system attached to a wheelchair that can open an automatic door for a certain period of time at the same common frequency when a disabled person or an elderly person moves in a wheelchair. An oscillator is disclosed.

Japanese Patent No. 4487458 JP 2011-185010 A JP 2002-285756 A

  However, the above Patent Documents 1 to 3 have the following problems.

  In Patent Documents 1 and 2, various problems occur when a remote key (electronic key, remote controller) is used by a physically handicapped person or an elderly person. More specifically, no countermeasure is considered when the remote key is accidentally dropped. For example, when a physically handicapped person or an elderly person is using a wheelchair, the remote key cannot be picked up from the wheelchair. Moreover, even if a physically handicapped person or an elderly person uses a crutch, an outdoor walker, etc., it is difficult and dangerous to pick up the dropped remote key. Also, if you lose your remote key when you are away from home (they are more likely to be elderly) or are stolen, you will not be able to enter your home even if you go home.

  In order to solve these problems, as disclosed in Patent Document 3 above, a remote key (remote control oscillator) is used as a mobility aid (wheelchair, crutch, etc.) used by persons with physical disabilities and the elderly. It is possible to install. However, in Patent Document 3, no measures are taken when the remote key is removed from the movement assisting tool, or the house is stolen together with the movement assisting tool being stolen.

  Therefore, an object of the present invention is to provide a transmitter for an automatic door device that can take measures against crime damage even if the remote key is removed from the movement assisting tool or the movement assisting tool is stolen. There is.

  A transmitter for an automatic door device according to the present invention is a transmitter for remotely controlling the opening and closing of an automatic door, and includes a transmitter body including a control unit and a case for controlling the operation of the transmitter, and the transmitter. A fixing tool for fixing the main body to the movement assisting tool, and the transmitter main body further includes a personal authentication device, and only when the personal authentication is confirmed by the result of collation by the personal authentication device, The control unit becomes operable.

  According to the present invention, even if the remote key is removed from the movement assisting tool or the movement assisting tool is stolen, it is possible to take measures against crime damage.

[Embodiment 1]
First, with reference to FIG. 1 thru | or FIG. 5, the automatic door apparatus 10 to which the transmitter (remote key) 30 which concerns on the 1st Embodiment of this invention is applied is demonstrated in detail.

  The illustrated automatic door device 10 is a device that can remotely open and close the front door 20 of a general house using a remote key 30.

  FIG. 1 is a diagram showing a schematic configuration of an automatic door device 10. FIG. 2 is a view showing a part of the inner surface of the front door 20 of the automatic door device 10. FIG. 3 is a block diagram of the automatic door device 10. FIG. 4 is an external view showing the remote key 30 attached to the wheelchair 40. FIG. 5 is a block diagram of the remote key 30.

  As will be described later, the present invention is characterized by the remote key 30, but in order to facilitate understanding of the present invention, first, an outline of the automatic door device 10 will be described with reference to FIGS. To do.

  The remote key 30 is used by being attached to a movement assisting tool such as a handicapped person represented by the wheelchair 40. The mobility aid is not limited to the wheelchair 40, and may be other things such as a crutch, an electric wheelchair mainly used by elderly people, and an outdoor walker. Here, for the sake of simplicity, the wheelchair 40 will be described as an example.

  The automatic door device 10 includes a receiver 12, a controller 14, an electric lock 16, and a door driving device 18. The entrance door 20 is driven to open and close by a door driving device 18 as will be described later. The receiver 12 receives a signal (transmitted radio wave) from a remote key 30 described later, demodulates and shapes the received signal, and sends the demodulated data to the controller 14. The controller 14 determines demodulated data. Although the receiver 12 and the controller 14 are attached to the inner surface of the entrance, the receiver or the receiving antenna portion of the receiver may be attached to the outer surface of the entrance depending on the state of the radio wave received from the remote key. The electric lock 16 is integrated with the door knob. The electric lock 16 unlocks or locks the entrance door 20 in response to the unlock signal or the lock signal from the controller 14. The door driving device 18 opens and closes the front door 20 in response to an opening command (door opening signal) or a closing command (door closing signal) from the controller 14.

  The controller 14 includes a microcomputer having a storage unit such as a central processing unit (CPU), a read-only memory (ROM), and a random access memory (RAM). In the storage unit of the controller 14, user data (that is, identification information unique to the remote key 30) is registered in advance as registration information. The identification information unique to the remote key 30 is abbreviated as “key identification information”.

  Next, the external appearance of the remote key 30 will be described with reference to FIG.

  The remote key 30 incorporates a battery as a power source, but a large-capacity battery (for example, a cylindrical lithium battery (not shown)) that can be used until the end of the life of the remote key 30 (for example, about 10 years) is used. This eliminates the need for battery replacement and eliminates the risk of running out of batteries.

  The case 30a of the remote key 30 is sealed for waterproofing.

  The remote key 30 includes a metal band 32 that secures it to the component 41 of the wheelchair 40. The function is the same even if other fixing means are used, such as fixing the remote key 30 to the component member 41 of the wheelchair 40 with a bolt instead of the metal band 32. The remote key 30 includes an opening operation push button switch 34 and a closing operation push button switch 35. The opening operation push button switch 34 and the closing operation push button switch 35 may be easily identified by changing colors or shapes.

  The opening operation push button switch 34 and the closing operation push button switch 35 are also simply referred to as “open button” and “close button”, respectively.

  Various attachment points of the remote key 30 to the wheelchair 40 may be selected by the user, or an open button and a close button separately connected to the transmitter main body may be independently attached. For example, even a handicapped person may attach the push button switches 34 and 35 to the wheelchair 40 independently of the transmitter main body at a position where the push button switches 34 and 35 can be operated with feet, elbows, necks and shoulders. Thereby, even a handicapped person who has conventionally been difficult to operate the open button and the close button can use the remote key 30.

  Thus, since the remote key 30 was attached to the wheelchair 40, the risk of dropping or losing the remote key 30 can be avoided. Further, since there is no need to take out the remote key from a pocket or the like unlike a conventional small remote key, there is no risk of accidentally dropping the remote key 30 during operation. Further, by enlarging the open button 34 and the close button 35, it is possible to easily operate (push) them. Furthermore, since the remote key 30 can be prevented from being robbed, the risk of becoming a victim of crime can be reduced. As a result, security performance can be improved.

  Next, the security performance will be explained a little. In the future, as the city becomes barrier-free and people with physical disabilities enjoy shopping and leisure on their own, crimes targeting this are expected to increase.

  Needless to say, physically handicapped and elderly people are physically weak and cannot take agile behavior when they are involved in a crime.

  The remote key 30 is the same as the house key, and if it is robbed by force or an elderly person is skillfully scammed, it can lead to a secondary crime such as ruining the house, and there is no prevention as much as possible. must not.

  Since the remote key 30 attached to a mobility aid such as a wheelchair 40 is difficult to remove (takes more time) than possessing it alone, damage from robbery and fraud can be prevented.

  The wheelchair 40 may be stolen, but if the remote key 30 is not removed, the wheelchair 40 itself must be brought close to the entrance door 20 of the house. Such prominent behavior is the most disliked by criminals, and as a result leads to deterrence of crime.

  Next, the internal configuration of the remote key 30 will be described with reference to FIG.

  The illustrated remote key 30 further includes an LED (light emitting diode) 36, a buzzer 37, and an antenna 38.

  The remote key 30 includes a transmitter main body (key main body) 300 including a control unit (described later) that controls the operation of the remote key 30 and the case 30a.

  The metal band 32 functions as a fixing tool for fixing the transmitter main body (key main body) 300 to the wheelchair (movement assisting tool) 40.

  As described above, the function is the same even if other fixing means such as the remote key 30 is fixed to the constituent member 41 of the wheelchair 40 with a bolt instead of the metal band 32.

  Connected to the transmitter main body 300 are an open operation push button switch (open button) 34, a close operation push button switch (close button) 35, an LED 36, a buzzer 37, and an antenna 38.

  The transmitter body 300 includes a central processing unit (CPU) 310, a read-only memory (ROM) 320, an electrically erasable programmable ROM (EEPROM) 325, a random access memory (RAM) 330, an LED driving circuit 340, a buzzer driving circuit 350, A transmission unit 360, a detection unit 370, and a timer 380 are provided.

  The combination of the CPU 310, the ROM 320, the EEPROM 325, and the RAM 330 operates as the control unit that controls the operation of the remote key 30.

  The CPU 310 is supplied with an opening operation signal from the opening operation push button switch 34 and supplied with a closing operation signal from the closing operation push button switch 35. In response to the opening operation signal or the closing operation signal, the CPU 310 sends the LED driving signal and the buzzer driving signal to the LED driving circuit 340 and the buzzer driving circuit 350, respectively. The LED drive circuit 340 turns on the LED 36 in response to the LED drive signal. The buzzer drive circuit 350 sounds the buzzer 37 in response to the buzzer drive signal.

  The EEPROM 325 stores identification information (key identification information) unique to the remote key 30.

  When receiving the opening operation signal or the closing operation signal, the CPU 310 sends the key identification information stored in the EEPROM 325 and the door opening signal or the door closing signal to the transmission unit 360. The door open signal and the door close signal are called function codes. The transmission unit 360 modulates the carrier wave with the key identification information and the function code, and transmits the modulated wave as a transmission radio wave via the antenna 38.

  The detection unit 370 detects that the remote key 30 has been removed from the wheelchair 40 or that the case 30a has been opened. Timer 380 is activated in response to a detection signal from detection unit 370. The timer 380 sends a time-up signal to the CPU 310 when a predetermined time has elapsed since activation. CPU 310 stops its operation from the time when timer 380 is activated until the time-up signal is received.

  Therefore, the timer 380 functions as a stop unit that stops the operation of the control units (310, 320, 325, 330) for a predetermined time in response to the detection signal from the detection unit 370. The predetermined time set in the timer 380 needs to be sufficiently long for the purpose of preventing a secondary crime, and is set to several hours to several tens of hours, for example. The predetermined time may be an infinite time. A case where the predetermined time is infinite will be described later as a modified example.

  Next, the operation of the remote key 30 when the detection unit 370 includes a detection unit that detects that the remote key 30 has been removed from the wheelchair 40 will be described.

  Assume that the remote key 30 is attached to the wheelchair 40. In this case, the detection unit 370 sends a signal of logic “L” level to the timer 380. Therefore, the timer 380 is not activated, and the timer 380 also sends a signal of logic “L” level to the CPU 310. As a result, since the CPU 310 operates, the remote key 30 functions normally.

  Assume that the remote key 30 is removed from the wheelchair 40 in this state. At this time, the detection unit 370 operates, and the detection unit 370 inverts the output from the logic “L” bell to the logic “H” level. In other words, detection unit 370 sends a detection signal of logic “H” level to timer 380. In response to the logic “H” level detection signal, the timer 380 is started, and at the same time, the timer 380 sends a logic “H” level signal to the CPU 310. As a result, the operation of the CPU 310 stops and the remote key 30 does not function.

  When the timer 380 expires after a predetermined time has elapsed since the timer 380 was activated, the timer 380 sends a logic “L” level time-up signal to the CPU 310 from that point. As a result, the CPU 310 returns and the remote key 30 functions normally.

  Note that the operation of the remote key 30 in the case where the detection unit 370 includes a detection unit that detects that the case 30a has been opened is the same as described above, and thus the description of the operation is omitted.

  A specific example of the detection unit 370 will be described in detail later with reference to the drawings.

  FIG. 6 is a flowchart for explaining the operation of the controller 14.

  Next, the operation of the automatic door device 10 will be described with reference to FIGS. Here, an operation when the user opens and closes the front door 20 when returning home will be described.

  Usually, the entrance door 20 is closed, and the electric lock 16 locks the entrance door 20. Further, the remote key 30 does not transmit a transmission radio wave.

  In this state, suppose that the user who got on the wheelchair 40 with the remote key 30 came home. The user operates the remote key 30 by pressing the open button 34 of the remote key 30 near the entrance door 20.

  The communication distance of the remote key 30 varies depending on the size of the entrance door 20 and the surroundings of the entrance door 20. In the present embodiment, the communication distance of the remote key 30 is set in the range of 2 m to 3 m. Further, the remote key 30 is set to transmit a transmission radio wave when it is kept pressed for a predetermined time or longer. Thereby, unnecessary operations can be prevented and battery consumption can be avoided. In this embodiment, the fixed time is set in a range of 1 second to 3 seconds.

  Since the open button 34 is pressed in the remote key 30, an open operation signal is supplied from the open button 34 to the CPU 310. In response to the opening operation signal, the CPU 310 sends the LED drive signal and the buzzer drive signal to the LED drive circuit 340 and the buzzer drive circuit 350, respectively. In response to the LED drive signal, the LED drive circuit 340 lights the LED 36. In response to the buzzer driving signal, the buzzer driving circuit 350 sounds the buzzer 37.

  In response to the opening operation signal, the CPU 310 reads key identification information from the EEPROM 325, and sends the key identification information and a door opening signal as a function code to the transmission unit 360. The transmission unit 360 modulates the carrier wave with the key identification information and the function code (door opening signal), and transmits the modulated wave as a transmission radio wave to the receiver 12 of the front door 20 via the antenna 38.

  The receiver 12 receives this transmission radio wave, demodulates and shapes the received signal, and sends the demodulated data (key identification information and function code (door opening signal)) to the controller 14.

  With reference to FIG. 6, the controller 14 first collates the key identification information with the registered information registered in advance (step S101). If the key identification information matches the registration information (YES in step S101), the controller 14 determines the function code that is sent subsequently (step S102). In this example, since the function code is a door open signal, the controller 14 sends an unlock signal to the electric lock 16 (step S103). In response to the unlock signal, the electric lock 16 unlocks the front door 20. Subsequently, the controller 14 sends a door opening signal to the door driving device 18 (step S104). In response to the opening signal, the door driving device 18 opens the entrance door 20. At this time, the door driving device 18 or the controller 14 may emit a warning sound such as “door opens” from a speaker (not shown).

  When the front door 20 is fully opened, the user enters the house and presses the close button 35 of the remote key 30.

  Since the close button 35 is pressed in the remote key 30, a close operation signal is supplied from the close button 35 to the CPU 310. In response to the closing operation signal, the CPU 310 sends an LED drive signal and a buzzer drive signal to the LED drive circuit 340 and the buzzer drive circuit 350, respectively. In response to the LED drive signal, the LED drive circuit 340 lights the LED 36. In response to the buzzer driving signal, the buzzer driving circuit 350 sounds the buzzer 37.

  In response to the closing operation signal, the CPU 310 reads key identification information from the EEPROM 325 and sends the key identification information and a door closing signal as a function code to the transmission unit 360. The transmission unit 360 modulates the carrier wave with the key identification information and the function code (door closing signal), and transmits the modulated wave as a transmission radio wave to the receiver 12 of the entrance door 20 via the antenna 38.

  The receiver 12 receives this transmission radio wave, demodulates and shapes the received signal, and sends demodulated data (key identification information and function code (door closing signal)) to the controller 14.

  Referring to FIG. 6 again, the controller 14 first collates the key identification information with the registered information registered in advance (step S101). If the key identification information matches the registration information (YES in step S101), the controller 14 determines the function code that is sent subsequently (step S102). In this example, since the function code is a door closing signal, the controller 14 sends a door closing signal to the door driving device 18 (step S105). In response to the closing signal, the door driving device 18 closes the entrance door 20. At this time, the door driving device 18 or the controller 14 may emit a warning sound such as “door closes” from a speaker (not shown). Subsequently, the controller 14 sends a lock signal to the electric lock 16 (step S106). In response to the locking signal, the electric lock 16 locks the entrance door 20.

  Next, effects of the first exemplary embodiment of the present invention will be described.

  According to the first embodiment of the present invention, the following effects can be obtained by attaching the remote key 30 to the movement assisting tool 40.

1) Since the remote key 30 is attached to the mobility aid (wheelchair) 40, the risk of dropping or losing the remote key 30 can be eliminated.
2) Since there is no need to take out a small remote key from a pocket or the like as in the prior art, there is no risk of accidentally dropping the remote key 30 during operation. In addition, the open button 34 and the close button 35 can be enlarged so that they can be pushed easily.
3) Since a large-capacity battery can be mounted, it is not necessary to replace the battery until the end of the life of the remote key 30 (for example, about 10 years), and there is no fear of battery exhaustion.
4) Even a handicapped person can operate the open button 34 and the close button 35 on the feet, knees, neck and shoulders, and the handicapped person who has been difficult to operate can use the remote key 30.
5) There is little risk of becoming a victim of crime, such as the remote key 30 being robbed, and security performance is high.

  Further, according to the first embodiment of the present invention, when the remote key 30 is removed from the movement aid 40 or the case 30a is opened, the operation of the remote key 30 is stopped for a predetermined time. There are also such effects.

  6) Even if the mobility aid 40 is stolen and the thief removes the remote key 30 from the mobility aid 40 or opens the case 30a, while the remote key 30 is stopped operating, It is possible to take measures against crime damage, such as deleting registration of the stolen remote key 30 (that is, registration information registered in the controller 14).

  Note that the registration information registered in the controller 14 is deleted by, for example, the “personal identification data registration or deletion device of the access control system” described in Japanese Patent No. 4660262 already acquired by the inventor. By using it, it can be done easily.

  The configuration of the remote key 30 is not limited to the first embodiment, and various changes can be made. For example, the LED 36 and the LED drive circuit 340, the buzzer 37, and the buzzer drive circuit 350 may be omitted. Furthermore, an “electronic key” as described in Patent Document 1 may be used as the remote key. In that case, since the user does not need to perform any operation, the opening push button switch (open button) 34 and the closing push button switch (close button) 35 can be omitted.

  Next, the detection unit 370 according to the first embodiment used for the remote key 30 will be described with reference to FIG. The illustrated detection unit 370 is an example of a detection unit that detects that the remote key (transmitter) 30 has been removed from the wheelchair (movement aid) 40.

  7A is a perspective view illustrating a state in which the remote key 30 is attached to the wheelchair 40, and FIG. 7B is a perspective view illustrating a state in which the remote key 30 is detached from the wheelchair 40.

  The illustrated detection unit 370 includes a detection member 372 and a micro switch 374. The detection member 372 is a member that detects that the remote key 30 has been removed from the component member 41 of the wheelchair 40. The micro switch 374 is a switch that operates when the remote key 30 is removed from the component 41 of the wheelchair 40.

  In a normal state (that is, a state before the remote key 30 is attached to the wheelchair 40 as shown in FIG. 7B), the tip of the detection member 372 protrudes from the attachment surface of the remote key 30 to the outside. It has become. Therefore, the detection member 372 is separated from the micro switch 374.

  In this state, it is assumed that the remote key 30 is attached to the component member 41 of the wheelchair 40 as shown in FIG. In this case, the tip of the detection member 372 is pushed into the remote key 30 by the component member 41 of the wheelchair 40. As a result, the detection member 372 comes into contact with the micro switch 374, and the micro switch 374 is activated. At this time, the micro switch 374 sends a logic “L” level signal to the timer 380 (FIG. 5).

  From this state, it is assumed that the remote key 30 is removed from the component member 41 of the wheelchair 40 as shown in FIG. In this case, the tip of the detection member 372 protrudes outward from the mounting surface of the remote key 30. Therefore, the detection member 372 is separated from the micro switch 374. As a result, microswitch 374 inverts its output and transitions from a logic “L” level to a logic “H” level. That is, microswitch 374 sends a logic “H” level detection signal to timer 380 (FIG. 5).

  In the first embodiment, a combination of the detection member 372 and the micro switch 374 is used as the detection unit 370 that detects that the remote key 30 has been removed from the component member 41 of the wheelchair 40. Is not limited to this.

  For example, it is assumed that the constituent member 41 of the wheelchair 40 to which the remote key 30 is attached is made of a magnetic material. In this case, the detection unit 370 may be configured by a combination of a magnet and a reed switch or a combination of a magnet and a Hall element. Such a detection unit 370 detects a change in magnetic force when the remote key 30 is removed from the component member 41 of the wheelchair 40.

  Next, a detection unit 370 according to the second embodiment used for the remote key 30 will be described with reference to FIG. The illustrated detection unit 370 is an example of a detection unit that detects that the case 30a of the remote key 30 has been opened.

  FIG. 8 is a perspective view showing a state in which the remote key 30 is attached to the wheelchair 40.

  The illustrated detection unit 370 includes a tamper photoelectric element 376 provided inside the case 30 a of the remote key 30. The tamper photoelectric element 376 detects external light when the case 30a of the remote key 30 is opened. The tamper photoelectric element 376 is made of, for example, a photodiode.

  The tamper photoelectric element 376 outputs a logic “L” level signal when the case 30 a of the remote key 30 is closed. On the other hand, when the case 30a of the remote key 30 is opened, the tamper photoelectric element 376 sends a detection signal of logic “H” level to the timer 380 (FIG. 5).

  In the second embodiment, the tamper photoelectric element 376 is used as the detection unit 370 that detects that the case 30a of the remote key 30 is opened, but the detection unit 370 is not limited thereto.

  For example, it is assumed that the cover of the case 30a of the remote key 30 is attached with screws. In this case, the detection unit 370 may include a micro switch that detects removal of the lid of the case 30a.

  However, such a microswitch cannot be used when the lid of the case 30a is attached with an adhesive or the like in order to ensure a long-term waterproof function. This is because the location where the case 30a of the remote key 30 can be opened cannot be specified. Therefore, it is desirable to use a tamper photoelectric element 376 that detects external light as shown in FIG. 8 as the detection unit 370 that detects that the case 30a of the remote key 30 has been opened. This is because such a tamper photoelectric element 376 is not affected by the location where the case 30a of the remote key 30 can be opened.

  Next, a detection unit 370 according to a third embodiment used for the remote key 30 will be described with reference to FIG. The illustrated detection unit 370 is an example of a detection unit that detects both removal of the remote key (transmitter) 30 from the wheelchair (movement aid) 40 and opening of the case 30a of the remote key 30. Is shown.

  9A is a perspective view showing a state in which the remote key 30 is attached to the wheelchair 40, and FIG. 9B is a perspective view showing a state in which the remote key 30 is detached from the wheelchair 40.

  That is, the detection unit 370 according to the third embodiment includes a detection unit that combines the first embodiment and the second embodiment. Therefore, the illustrated detection unit 370 includes a detection member 372, a micro switch 374, and a tamper photoelectric element 376.

  Since each component has already been described, description thereof is omitted.

  Next, a detection unit 370 according to a fourth embodiment used for the remote key 30 will be described with reference to FIG. The illustrated detection unit 370 is an example of a detection unit that detects both removal of the remote key (transmitter) 30 from the wheelchair (movement aid) 40 and opening of the case 30a of the remote key 30. Is shown.

  FIG. 10 is a perspective view showing a state in which the remote key 30 is attached to the wheelchair 40.

  The illustrated detection unit 370 includes a tamper photoelectric element 376 and a light incident window 378. The light entrance window 378 is opened at the case 30 a at a connection portion (connection portion) between the remote key 30 and the component member 41 of the wheelchair 40. The tamper photoelectric element 376 detects a change in external light input through the light incident window 378.

  Accordingly, in the tamper photoelectric element 376 configured as described above, not only the external light is detected when the case 30a of the remote key 30 is opened, but the remote key (transmitter) 30 is also used as a wheelchair (movement aid). Even when it is removed from 40, it detects external light. When the external light is detected, the tamper photoelectric element 376 sends a detection signal having a logic “H” level to the timer 380 (FIG. 5).

[Modification 1]
Next, the remote key 30A according to the first modification of the present invention will be described in detail with reference to FIG. FIG. 11 is a block diagram of the remote key 30A.

  As will be described later, the illustrated remote key 30A has the same configuration as the remote key 30 shown in FIG. 5 except that the configuration of the transmitter body is different. Therefore, the reference numeral 300A is attached to the transmitter body.

  The transmitter main body 300A has the same configuration as the transmitter main body 300 shown in FIG. 5 except that the timer 380 is omitted and instead the detection unit 370 and the CPU 310 are directly connected by the transmission line 380A. To work. Therefore, the same components as those shown in FIG. 5 are denoted by the same reference numerals, and description thereof is omitted for the sake of simplicity.

  Assume that the detection unit 370 removes the remote key (transmitter) 30A from the wheelchair (movement aid) 40 or opens the case 30a of the remote key 30A. In this case, the detection signal of the detection unit 370 is sent to the CPU 310 as a stop signal via the transmission line 380A.

  In response to the stop signal, the CPU 310 stops its operation permanently (irreversibly). In other words, due to the software configuration, the CPU 310 performs the initialization operation only when the power is first applied after writing the software. Once the CPU 310 stops, the CPU 310 does not initialize, so the CPU 310 does not restart.

  In this case, the remote key 30A may not be operated until the software of the CPU 310 is written again.

  According to the first modification of the present invention, the following effects can be obtained.

  Even if the mobility aid 40 is stolen and the thief removes the remote key 30A from the mobility aid 40 or opens the case 30a, the remote key 30A stops its operation permanently. It becomes possible to take measures against crime damage.

[Modification 2]
Next, a remote key 30B according to a second modification of the present invention will be described in detail with reference to FIG. FIG. 12 is a block diagram of the remote key 30B.

  As will be described later, the illustrated remote key 30B has the same configuration as the remote key 30 shown in FIG. 5 except that the configuration of the transmitter body is different. Therefore, the reference numeral 300B is attached to the transmitter body.

  The transmitter main body 300B is provided with a switch 307 in a lithium battery 305 that supplies power to each component, and supplies an output signal from the timer 380 not to the CPU 310 but to the switch 307. 5 has the same configuration as the transmitter main body 300 shown in FIG. Therefore, the same components as those shown in FIG. 5 are denoted by the same reference numerals, and description thereof is omitted for the sake of simplicity.

  In the first embodiment shown in FIG. 5, the output signal of the timer 380 is supplied to the CPU 310.

  On the other hand, in the second modified example shown in FIG. 12, the output signal of the timer 380 is supplied to the switch 307. The switch 307 is turned off after the timer 380 is activated until a time-up signal is received. In other words, while the signal of the logic “H” level is supplied from the timer 380, the switch 307 is turned off and the power supply to each component is cut off.

  According to the second modification of the present invention, when the remote key 30B is removed from the movement assisting tool 40 or the case 30a is opened, the power of the remote key 30B is cut off for a predetermined time. There is an effect similar to the form.

  That is, even if the mobility aid 40 is stolen and the thief removes the remote key 30B from the mobility aid 40 or opens the case 30a, the remote key 30B is powered off. It is possible to take measures against crime damage, such as deleting registration of the stolen remote key 30B (that is, registration information registered in the controller 14).

[Modification 3]
Next, a remote key 30C according to a third modification of the present invention will be described in detail with reference to FIG. FIG. 13 is a block diagram of the remote key 30C.

  The remote key 30C shown in the figure operates with the same configuration as the remote key 30A shown in FIG. 11 except that the configuration of the transmitter body is different, as will be described later. Therefore, the reference numeral 300C is attached to the transmitter body.

  The transmitter main body 300C is provided with a switch 307 in the lithium battery 305 that supplies power to each component, and the detection signal (stop signal) from the detection unit 370 is supplied to the switch 307 instead of the CPU 310. Except for the transmitter main body 300A shown in FIG. Therefore, the same components as those shown in FIG. 11 are denoted by the same reference numerals, and description thereof will be omitted for the sake of simplicity.

  In the first modification shown in FIG. 11, a detection signal (stop signal) from the detection unit 370 is supplied to the CPU 310 via the transmission line 380A.

  On the other hand, in the third modified example shown in FIG. 13, a detection signal (stop signal) from the detection unit 370 is supplied to the switch 307 via the transmission line 380A. The switch 307 is turned off permanently (irreversibly) when it receives a stop signal. As a result, power supply to each component is permanently cut off.

  Instead of the switch 307, a fuse may be used. That is, when the stop signal is received, the fuse is blown.

  According to the third modification of the present invention, the same effects as those of the first modification described above can be obtained.

  That is, even if the mobility aid 40 is stolen and the thief removes the remote key 30C from the mobility aid 40 or opens the case 30a, the power supply to the remote key 30C is permanently cut off. Therefore, it becomes possible to take measures against crime damage.

[Modification 4]
Next, a remote key 30D according to a fourth modification of the present invention will be described in detail with reference to FIG. FIG. 14 is a block diagram of the remote key 30D.

  As shown later, the illustrated remote key 30D has the same configuration as the remote key 30 shown in FIG. 5 except that the configuration of the transmitter body is different. Therefore, the reference numeral 300D is attached to the transmitter body.

  The transmitter main body 300D has the same configuration as the transmitter main body 300 shown in FIG. 5 and operates except that it further includes a counter 390 and an AND gate 395. Therefore, the same components as those shown in FIG. 5 are denoted by the same reference numerals, and description thereof is omitted for the sake of simplicity.

  As described above, the remote key 30 of the first embodiment is extremely effective for preventing the remote key 30 from being stolen and preventing secondary crimes.

  However, when the remote key 30 is actually attached to the wheelchair (movement assist tool) 40, it is necessary to adjust the attachment position of the remote key 30. In order to attach the remote key 30 to the position of the wheelchair 40 that is most convenient for the user, the remote key 30 is actually attached to the wheelchair 40 several times. It may be necessary to remove it from the wheelchair 40.

  At that time, in the configuration of the remote key 30 shown in FIG. 5, the removal preventing function is activated, so that adjustment when the remote key 30 is installed on the wheelchair 40 becomes difficult.

  Therefore, as a method for preventing the removal prevention function from functioning when adjusting the remote key, the following method can be considered. The first method is a method of providing a start switch for operating the removal prevention function. The second method is a method in which a reed switch or a hall element is built in the remote key, and the reed switch or the hall element is operated by applying a magnetic force from the outside to activate the removal preventing function. The third method is a method of activating the removal prevention function under a condition that the remote key open button and the close button are simultaneously pressed for a predetermined time. By adding a function for realizing these methods to the remote key shown in FIG. 5, it is possible to avoid activation of the removal prevention function during adjustment.

  However, these methods have the following problems when adjusting the mounting position of the remote key. The first method has a problem that the start switch is erroneously operated. The second method has a problem that a magnetic force is accidentally applied from the outside. The third method has a problem that the open button and the close button are accidentally pressed simultaneously. If the anti-removal function is activated by such an erroneous operation, the operation of the remote key is stopped permanently, or the operation is stopped for several hours to several days, and there is a risk that the subsequent adjustment cannot be performed.

  The remote key 30D according to the fourth modification is one solution for solving this problem. That is, the transmitter main body 300D of the remote key 30D is configured to block the detection signal sent from the detection unit 370 to the timer (stop means) 380 until a predetermined condition is satisfied.

  More specifically, the counter 390 counts the number of opening operation signals output from the opening operation push button switch (open button) 34 (hereinafter referred to as “the number of opening operations”). While the number of opening operations is less than the predetermined number, the counter 390 outputs a logic “L” level signal. When the number of operations reaches a predetermined number, counter 390 outputs a count-up signal having a logic “H” level. The predetermined number of times set in the counter 390 may be larger than the number of times that the opening operation by the open button 34 is expected to be performed in the above-described adjustment work. For example, the predetermined number of times is set in a range between several times to several hundred times.

  As described above, in the fourth modification, the “predetermined condition” is when the number of operations (number of opening operations) of the remote key 40D reaches a predetermined number.

  Note that the counter 390 performs an irreversible operation that is not reset even when the power is turned off once the counter 390 counts up.

  An output signal (count up signal) of the counter 390 is supplied to one input terminal of the AND gate 395. A detection signal from the detection unit 370 is supplied to the other input terminal of the AND gate 395.

  Therefore, the AND gate 395 operates to invalidate the detection signal of the detection unit 370 until the count-up signal is supplied from the counter 390. Therefore, the combination of the counter 390 and the AND gate 395 functions as a blocking unit that blocks the detection signal sent from the detection unit 370 to the timer (stop unit) 380 until a predetermined condition is satisfied.

  In the fourth modified example, the counter 390 counts only the number of opening operation signals (opening operation times) output from the opening operation push button switch (open button) 34, but is not limited thereto. For example, the counter 390 counts not only the number of opening operations but also the number of closing operation signals output from the closing operation push button switch (closing button) 35 (hereinafter referred to as “the number of closing operations”). May be.

  In the fourth modification example having such a configuration, in addition to the effects 1) to 6) of the first embodiment described above, the following effects are also obtained.

  7) Since the removal prevention function is stopped for a certain number of operations after the remote key 30D is used for the first time, the remote key 30D can be freely attached to and removed from any position on the wheelchair (movement aid) 40. And can be adjusted many times to the optimum position by the user.

  In the fourth modified example, the blocking means is composed of a combination of the counter 390 and the AND gate 395, but the blocking means is not limited to this. For example, instead of the AND gate 395, a combination of a relay and a contact may be used.

  Further, the count-up signal from the counter 390 may be supplied to the CPU 310 as indicated by a broken line in FIG. In this case, the CPU 310 may control the LED drive circuit 340 and the buzzer drive circuit 350 so as to change the color of the LED 36 and the sound of the buzzer 37 before and after receiving the count-up signal.

  Furthermore, as in the first to third modifications, the timer 380 serving as a stopping unit may be omitted or a stop signal may be supplied to the switch 307.

[Modification 5]
Next, a remote key 30E according to a fifth modification of the present invention will be described in detail with reference to FIG. FIG. 15 is a block diagram of the remote key 30E.

  As will be described later, the illustrated remote key 30E has the same configuration as the remote key 30D shown in FIG. 14 except that the configuration of the transmitter body is different. Therefore, the reference numeral 300E is attached to the transmitter body.

  The transmitter main body 300E has the same configuration as the transmitter main body 300D shown in FIG. 14 and operates except that a timer 390A is provided instead of the counter 390. Therefore, the same components as those shown in FIG. 14 are denoted by the same reference numerals, and description thereof is omitted for the sake of simplicity.

  Similar to the remote key 30D according to the fourth modified example, the transmitter main body 300E of the remote key 30E according to the fifth modified example may receive a timer (stop means) from the detecting unit 370 until a predetermined condition is satisfied. ) The detection signal sent to 380 is cut off.

  More specifically, the timer 390A starts an operation in response to an opening operation signal output from the opening operation push button switch (open button) 34 of the remote key 30E. While the specified time has not elapsed since the time when the operation was disclosed, the timer 390A outputs a logic “L” level signal. Then, when a predetermined time has elapsed from the time when the operation is disclosed, timer 390A outputs a time amplifier signal having a logic “H” level. The specified time set in the timer 390A may be longer than the time during which the opening operation by the open button 34 is expected to be performed in the adjustment operation described above. For example, the specified time is set in a range between several hours to several days.

  As described above, in the fifth modification, the “predetermined condition” is when a predetermined time has elapsed since the time when the remote key 30E was first operated.

  The output signal (time-up signal) of the timer 390A is supplied to one input terminal of the AND gate 395. A detection signal from the detection unit 370 is supplied to the other input terminal of the AND gate 395.

  Therefore, the AND gate 395 operates to invalidate the detection signal of the detection unit 370 until the time-up signal is supplied from the timer 390A. Therefore, the combination of the timer 390A and the AND gate 395 serves as a blocking unit that blocks the detection signal sent from the detection unit 370 to the timer (stop unit) 380 until a predetermined condition is satisfied.

  In the fifth modified example having such a configuration, in addition to the effects 1) to 6) of the first embodiment described above, the following effects are also achieved.

  7) Since the anti-removal function is stopped until a specified time has elapsed since the remote key 30E was first used, the remote key 30E can be freely attached to an arbitrary position of the wheelchair (movement aid) 40, Detachable and can be adjusted many times to the optimum position by the user.

  In the fifth modified example, the blocking means is composed of a combination of the timer 390A and the AND gate 395, but the blocking means is not limited to this. For example, instead of the AND gate 395, a combination of a relay and a contact may be used.

  Further, the time-up signal from the timer 390A may be supplied to the CPU 310 as indicated by the broken line in FIG. In this case, the CPU 310 may control the LED drive circuit 340 and the buzzer drive circuit 350 so as to change the color of the LED 36 and the sound of the buzzer 37 before and after receiving the time-up signal.

  Furthermore, as in the first to third modifications, the timer 380 serving as a stopping unit may be omitted or a stop signal may be supplied to the switch 307.

[Embodiment 2]
A transmitter (remote key) 30F according to the second embodiment of the present invention will be described in detail with reference to FIGS.

  FIG. 16 is an external view showing the remote key 30 </ b> F attached to the wheelchair 40. FIG. 17 is a block diagram of the remote key 30F.

  The illustrated remote key 30F has the same configuration as the remote key 30 shown in FIGS. 4 and 5 and operates except that the configuration of the transmitter body is different. Therefore, the reference numeral 300F is attached to the transmitter body.

  The transmitter main body 300F has the same configuration as that of the transmitter main body 300 shown in FIG. 5 and operates except that a personal authentication device 500 is provided instead of the detection unit 370 and the timer 380. Therefore, the same components as those shown in FIG. 5 are denoted by the same reference numerals, and description thereof is omitted for the sake of simplicity.

  The personal authentication device 500 is inserted between the push button switch (open button) 34 for opening operation and the CPU 310. The CPU 310 can operate only when the personal authentication is confirmed by the result of the collation by the personal authentication device 500.

  When the opening operation signal is supplied from the opening button 34, the personal authentication device 500 is turned on and is in an operating state. The illustrated personal authentication device 500 includes a contactless card reader 510 and an authentication unit 520. The non-contact card reader 510 reads personal identification data stored in the non-contact IC card 39 possessed by the user. The authentication unit 520 compares the personal identification data read from the non-contact IC card 39 with previously registered data, and if the data match, sends an opening operation signal to the CPU 310.

  Some people with physical disabilities cannot move their hands and fingers freely. Therefore, the non-contact IC card 39 is more convenient for the proximity IC card having a data reading distance of about 10 cm than the proximity IC card used for settlement such as for transportation.

  For users who cannot move their hands and arms freely, the open button 34 and the close button 35 may be separated from the transmitter main body 300F and operated with feet or shoulders. In this case, the non-contact card reader 510 is also installed at a position away from the transmitter main body 300F (for example, near the arm), and the non-contact IC card 39 is attached to the user's arm and always close to the non-contact card reader 510. You may make it leave. With such a configuration, when the open button 34 is operated, the non-contact card reader 510 operates and the personal identification data of the non-contact IC card 39 can be read.

  Next, the operation of the remote key 30F will be described.

  The user presses the open button 34 of the remote key 30F to open the entrance door 20 (FIG. 1). In response to the operation of the open button 34, the personal authentication device 500 is turned on, and the personal authentication device 500 enters an operating state.

  Next, the user brings the non-contact IC card 39 possessed closer to the non-contact card reader 510. Thereby, the non-contact card reader 510 reads the personal identification data stored in the non-contact IC card 39. The non-contact card reader 510 sends the read personal identification data to the authentication unit 520. Authentication unit 520 compares the read personal identification data with pre-registered data. If the data match, authentication unit 520 sends an open operation signal to CPU 310.

  Since the subsequent operation is the same as that of the first embodiment described above, description thereof is omitted.

  Note that there is no security problem when the close button 35 is pressed. Therefore, the closing operation signal from the closing button 35 is sent directly to the CPU 310.

  According to the second embodiment of the present invention, in addition to the effects 1) to 5) of the first embodiment described above, the following effects are also obtained.

  That is, according to the second embodiment of the present invention, the remote key 30F does not operate if there is no personal authentication medium such as the non-contact IC card 39, and the following effects are obtained.

  6) Even if the remote key 30F attached to the movement aid 40 or the movement aid 40 attached with the remote key 30F is stolen, the remote key 30F or the movement aid 40 that has been stolen is used. It is possible to prevent the next crime (house intrusion, etc.). As a result, it is possible to contribute to the safety of the physically handicapped person using the movement assisting tool 40.

  In the second embodiment, the non-contact IC card 39 is used as the personal authentication medium. However, the present invention is not limited to this. For example, it goes without saying that the same effect can be obtained by using biometric authentication such as fingerprints, voiceprints, irises, vein patterns, etc., or entering a personal identification number using a numeric keypad as a personal authentication medium.

[Embodiment 3]
An automatic door device 10A to which a transmitter (remote key) 30G according to a third embodiment of the present invention is applied will be described in detail with reference to FIGS.

  The illustrated automatic door device 10A is a device that can remotely open and close the front door 20 of a general house using a remote key 30G.

  FIG. 18 is a diagram showing a schematic configuration of the automatic door device 10A. FIG. 19 is a block diagram of the automatic door device 10A. FIG. 20 is an external view showing the remote key 30G attached to the wheelchair 40. FIG. FIG. 21 is a block diagram of the remote key 30G.

  The automatic door device 10A has the same configuration as the automatic door device 10 shown in FIG. 1 and operates except that the operation of the controller is different as will be described later. Therefore, the reference numeral 14A is attached to the controller.

  The controller 14A includes a microcomputer having a storage unit such as a central processing unit (CPU), a read-only memory (ROM), and a random access memory (RAM).

  In the automatic door device 10 shown in FIG. 1, identification information (key identification information) unique to the remote key 30 is registered in advance in the storage unit of the controller 14 as registration information.

  On the other hand, in the automatic door apparatus 10A according to the third embodiment, the personal identification data of the user is registered in advance as registration information in the storage unit of the controller 14A.

  The illustrated remote key 30G has the same configuration as the remote key 30F shown in FIGS. 16 and 17 and operates except that the configuration of the transmitter body is different. Therefore, a reference numeral of 300G is attached to the transmitter body.

  The transmitter main body 300G has the same configuration as the transmitter main body 300F shown in FIG. 17 except that the authentication unit 520 and the EEPROM 325 are omitted, and the operation of the CPU is different as described later. To do. Therefore, the reference numeral 310A is assigned to the CPU.

  Next, inconveniences in the second embodiment described above that are solved in the third embodiment will be described.

  In the second embodiment, the personal authentication device 500 is incorporated in the remote key 30F, and the remote key 30F is operated by the authentication of the personal authentication medium 39.

  However, in the second embodiment, if an opening operation signal sent from the push button for opening operation (open button) 34 to the CPU 310 is known, the remote key 30F may be operated without the personal authentication medium 39. Can not be excluded.

  In the second embodiment, the remote key 30F needs to include an authentication unit 520 having a function of collating the read personal identification data with data registered in advance together with the contactless card reader 510. At the same time, it is necessary to incorporate a function for registering and deleting personal identification data stored in the non-contact IC card 39 in the authentication unit 520 in case the non-contact IC card 39 is lost. Therefore, not only the configuration of the personal authentication device 500 becomes complicated, but also there is a risk of increasing power consumption and reducing reliability.

  Further, when a plurality of wheelchairs 40 are used by a plurality of users without separation, all persons who use all personal authentication devices 500 built in the remote keys 30F attached to the plurality of wheelchairs 40 respectively. It is necessary to register the personal identification data of the non-contact IC card 39. Therefore, it takes time to register or delete the personal identification data of the non-contact IC card 39 in the authentication unit 520 of the personal authentication device 500.

  The third embodiment is an automatic door device 10A using a remote key 30G that eliminates such drawbacks.

  FIG. 22 is a flowchart for explaining the operation of the controller 14A.

  Next, the operation of the automatic door device 10A will be described with reference to FIGS. Here, an operation when the user opens and closes the front door 20 when returning home will be described.

  Usually, the entrance door 20 is closed, and the electric lock 16 locks the entrance door 20. Further, the remote key 30G does not transmit a transmission radio wave.

  In this state, suppose that the user who got on the wheelchair 40 with the remote key 30G came home. The user presses the open button 34 of the remote key 30G near the entrance door 20.

  When the open button 34 is pressed in the remote key 30G, the non-contact card reader 510 is turned on, and the non-contact card reader 510 enters an operating state.

  Next, when the non-contact IC card 39 possessed by the user is brought close to the non-contact card reader 510, the non-contact card reader 510 reads the personal identification data stored in the non-contact IC card 39. The non-contact card reader 510 sends the read personal identification data and the opening operation signal to the CPU 310A. CPU 310 </ b> A temporarily stores the read personal identification data in RAM 330. That is, the RAM 330 functions as a buffer.

  In response to the opening operation signal, the CPU 310A sends the LED drive signal and the buzzer drive signal to the LED drive circuit 340 and the buzzer drive circuit 350, respectively. In response to the LED drive signal, the LED drive circuit 340 lights the LED 36. In response to the buzzer driving signal, the buzzer driving circuit 350 sounds the buzzer 37.

  In response to the opening operation signal, the CPU 310A reads the personal identification data from the buffer (RAM) 330, and sends the personal identification data and the door opening signal as a function code to the transmission unit 360. The transmission unit 360 modulates the carrier wave with the personal identification data and the function code (door open signal), and transmits the modulated wave to the receiver 12 of the entrance door 20 via the antenna 38 as a transmission radio wave.

  The receiver 12 receives this transmission radio wave, demodulates and shapes the received signal, and sends demodulated data (personal identification data and function code (door opening signal)) to the controller 14A.

  Referring to FIG. 22, controller 14A first collates the personal identification data with registered information registered in advance (step S101A). If the personal identification data matches the registered information (YES in step S101A), the controller 14A determines the function code sent subsequently (step S102). In this example, since the function code is a door open signal, the controller 14A sends an unlock signal to the electric lock 16 (step S103). In response to the unlock signal, the electric lock 16 unlocks the front door 20. Subsequently, the controller 14A sends a door opening signal to the door driving device 18 (step S104). In response to the opening signal, the door driving device 18 opens the entrance door 20. At this time, the door driving device 18 or the controller 14A may emit a warning voice such as “door opens” from a speaker (not shown).

  When the entrance door 20 is fully opened, the user enters the house and presses the close button 35 of the remote key 30G.

  Since the close button 35 is pressed in the remote key 30G, the close operation signal is supplied from the close button 35 to the CPU 310A. In response to the closing operation signal, the CPU 310A sends the LED driving signal and the buzzer driving signal to the LED driving circuit 340 and the buzzer driving circuit 350, respectively. In response to the LED drive signal, the LED drive circuit 340 lights the LED 36. In response to the buzzer driving signal, the buzzer driving circuit 350 sounds the buzzer 37.

  In response to the closing operation signal, the CPU 310A reads the personal identification data from the buffer (RAM) 330, and sends the personal identification data and the door closing signal as a function code to the transmission unit 360. The transmission unit 360 modulates the carrier wave with the personal identification data and the function code (door closing signal), and transmits the modulated wave as a transmission radio wave to the receiver 12 of the front door 20 via the antenna 38.

  The receiver 12 receives this transmission radio wave, demodulates and shapes the received signal, and sends demodulated data (personal identification data and function code (door closing signal)) to the controller 14A.

  Referring to FIG. 22 again, controller 14A first collates the personal identification data with registered information registered in advance (step S101A). If the personal identification data matches the registered information (YES in step S101A), the controller 14A determines the function code sent subsequently (step S102). In this example, since the function code is a door closing signal, the controller 14A sends a door closing signal to the door driving device 18 (step S105). In response to the closing signal, the door driving device 18 closes the entrance door 20. At this time, the door driving device 18 or the controller 14 </ b> A may emit a warning sound such as “door closes” from a speaker (not shown). Subsequently, the controller 14A sends a lock signal to the electric lock 16 (step S106). In response to the locking signal, the electric lock 16 locks the entrance door 20.

  According to the third embodiment of the present invention, in addition to the effects 1) to 6) of the second embodiment described above, the following effects are also obtained.

  That is, according to the third embodiment of the present invention, since the personal identification data read by the non-contact card reader 510 is transmitted as it is, the following effects are obtained.

  7) A mechanism for registering / deleting personal identification data stored in the non-contact IC card 39 in the remote key 30G, a verification function, etc. are not required, so the remote key 30G installed in a mobility aid such as a wheelchair 40 The configuration of the system becomes simpler, and it is possible to improve the power consumption and the reliability of the device.

  8) Even when a plurality of people use a plurality of wheelchairs (movement aids) 40 without separation, it is only necessary to register the personal identification data of each non-contact IC card 39 in the controller 14A. Registration and deletion of identification data can be performed more easily.

  9) Further, in the case of the second embodiment, a person who knows the opening operation signal sent from the personal authentication device 500 to the CPU 310 sends an opening operation signal to the CPU 310 without using the non-contact IC card 39. The risk of creating can be eliminated.

  In the third embodiment, the non-contact IC card 39 is used as the personal authentication medium, but it is needless to say that the present invention is not limited to this. For example, it goes without saying that the same effect can be obtained by using biometric authentication such as fingerprints, voiceprints, irises, vein patterns, etc., or entering a personal identification number using a numeric keypad as a personal authentication medium.

  In addition, in the case of personal authentication by collation of the non-contact IC card 39 or the personal identification number, the personal identification data to be collated is not large, so it is suitable for outputting to the CPU 310A and transmitting the data.

[Modification 6]
Next, a remote key according to a sixth modification of the present invention is described.

  Although not shown, in the remote key according to the sixth modified example, the transmitter main body and the operation switch (open button, close button) and / or the power source battery are attached to a remote place of the same movement assisting tool, Are connected with a cable.

  In such a configuration, when each connection cable is disconnected, the control unit is configured to stop the operation of the remote key for a certain time after that even if the connection cable is connected again.

  The sixth modification will be described in more detail. The remote key usually has an open button and a close button on the transmitter body, but depending on the state of disability such as a physically handicapped person, hands and fingers may not be freely used. The same applies to elderly people.

  In such a case, the remote button open button and close button must be installed in a place that can be operated by the user, such as near the foot, shoulder, or neck. In that case, the transmitter body and the operation switches (open button, close button) are connected to each other by a cable.

  Further, when the personal authentication device is incorporated into the remote key as in the second embodiment, since the personal authentication device uses a large amount of power, the power supply dedicated to the personal authentication device is separate from the power source battery of the transmitter body. It is necessary to install a battery. In this case, the power battery and the personal authentication device are also connected using a cable.

  Furthermore, when using a contactless card reader as a personal authentication device, if the user cannot use his / her hand, attach a contactless IC card to the user's shoulder or foot, and place a contactless card reader near the user. In some cases, it must be installed. Even in such a case, it is necessary to connect the non-contact card reader and the transmitter body with a cable.

  In the sixth modification, crimes in the remote key using the cable are thus prevented. That is, in the sixth modification, when the cable connecting the transmitter main body and a device (operation switch, power supply battery, non-contact card reader, etc.) installed apart from the transmitter is cut, the cable is connected again. Even so, the remote key is configured to stop its operation for a certain period of time.

  In the case of a wheelchair, many have a structure in which metal pipes are combined. Therefore, if the connection cable is passed through the pipe, it is difficult to remove the device while the cable is connected.

  Therefore, in order to remove the device, the connection cable is cut once. As a result, when the remote key according to the sixth modification is used, even if the connection cable is connected again, the remote key stops its operation for a certain period of time, so that security can be maintained.

  Therefore, measures against crime damage can be taken by taking measures such as deleting the registration of the stolen remote key while the operation of the remote key is stopped.

[Modification 7]
Next, a remote key according to the seventh modification of the present invention is described.

  Although not shown, in the remote key according to the seventh modified example, the following means are further added to the sixth modified example (measures are taken).

  In the remote key according to the seventh modification, the core wire of the cable between the transmitter main body and the operation switch and / or the cable between the transmitter main body and the power supply battery is configured with more wires than the actual required number of the same color. ing.

  In the remote key according to the sixth modified example described above, the cable that connects between the transmitter body and each device is stripped from the portion of the cable that is exposed from the pipe, and transmitted using another electric wire. If the machine main unit and each device are connected and the power supply and signal are diverted to another electric wire, it becomes possible to avoid the operation stop of the remote key when the cable is cut.

  The seventh modified example prevents this problem.

  More specifically, the core wires of the cables (individual electric wires in the cables) are generally color-coded in order to make the connection destination easy to understand. Therefore, even when the coating of the core wire is peeled off and detoured by another electric wire, the detour destination electric wire can be easily found.

  Therefore, in the seventh modification, it is difficult to find a detour destination electric wire by placing all the core wires of the cable in the same color. Further, in the seventh modified example, since an excessive number of extra wires are inserted, it is difficult for a criminal to discriminate the signal wires and power wires that are actually used. As a result, it is possible to make it more difficult to process the electric wire and use it for crimes.

  The present invention has been described above with reference to the embodiments (examples) and modifications. However, the present invention is not limited to the above-described embodiments (examples) and modifications. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.

  For example, in the above-described embodiment (example) and modification, the transmitter main body (key main body) and the metal band (fixing tool) are configured integrally, but they may be configured separately. .
