Therefore, identification of ID includes identification by a recording medium such as an ID card in which the ID is recorded and identification by fingerprint authentication.

JP-A-9-326092

  However, since the traffic control device described in Patent Document 1 is a device that only a person who has been given an ID can pass through, the traffic control device is installed in a place where an unspecified number of people may pass. It was difficult to prevent human traffic through the door.

  The present invention has been made in view of the above-described circumstances, and the object thereof is to prevent a child such as an infant from passing through the door alone, and the infant and the parent can be together. It is an object of the present invention to provide an automatic door device that can open a door as necessary for passage.

In order to solve the above problems, the present invention proposes the following means.
An automatic door device according to the present invention is based on a door that can be opened and closed by an opening / closing drive unit, a detection unit that detects a moving body that enters a predetermined region near the door, and an opening instruction signal from the detection unit. A control unit that controls the open / close drive unit to open, a receiver that detects a predetermined signal emitted from a transmitter attached to the moving body, and the predetermined signal is received by the receiver. In the meantime, there are provided prohibiting means for prohibiting control based on the opening instruction signal, and releasing means for releasing the prohibiting means and controlling the opening / closing drive unit based on an operation of an operator.

According to the present invention, while the predetermined signal emitted from the transmitter is not received by the receiver, the detection unit detects that the moving body has entered a predetermined area near the door. Then, the opening instruction signal is transmitted from the detection unit to the control unit, and a drive signal is transmitted from the control unit to the opening / closing drive unit to drive the door to open.
On the other hand, when the predetermined signal emitted by the transmitter is received by the receiver, the opening instruction signal from the detection unit does not reach the opening / closing driving unit by the prohibiting unit, and the movement to the predetermined region The door will not open when the body enters.
Further, when the operator operates the release means while the signal emitted by the transmitter is received by the receiver, the prohibition by the prohibition means is released and the opening instruction signal is sent to the opening / closing drive part by the detection unit. Is transmitted, and the door is opened.
Further, when the operation of the releasing means by the operator is completed, the prohibiting means operates again to prohibit control of the door opening / closing operation. As a result, it is possible to suppress the transmitter and the mobile body having the transmitter from moving through the door.

The automatic door device according to the present invention preferably includes a contact sensor that detects a predetermined operation by the operator and issues a release signal for releasing the prohibition unit to the control unit.
According to this invention, even if the predetermined signal emitted by the transmitter is received by the receiver, the prohibiting means is canceled by performing a predetermined input operation on the contact sensor. The door is opened and closed.

Moreover, it is preferable that the automatic door device of the present invention detects the predetermined signal emitted by the transmitter in only one of a plurality of regions where the receiver is partitioned by the door.
According to this invention, when the transmitter is moved from one of the doors to the other of the doors, the door is opened by operating the releasing means to release the prohibiting means. On the other hand, when the transmitter is moved from the other side of the door to one side of the door, the prohibiting unit does not operate, so that the operation of the releasing unit is not required.

Moreover, it is preferable that the automatic door device of the present invention is an optical sensor that detects the presence or absence of the moving body by detecting reflected light of the light irradiated on the predetermined region by the detection unit.
According to the present invention, since the opening instruction signal is generated when the reflected light of the light applied to the predetermined area is blocked by the moving body, the intrusion of the moving body into the predetermined area is accurately detected. can do.

  According to the automatic door device of the present invention, the operation of the door by the detection unit is prohibited based on the predetermined signal emitted by the transmitter, and the door is temporarily operated by the release means. In addition, it is possible to prevent a child such as an infant from passing through the door alone, and to open the door as necessary, such as an infant and a parent passing together.

(First embodiment)
Hereinafter, an automatic door device according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view for explaining the configuration of the automatic door device. FIG. 2 is a left side view for explaining the configuration of the automatic door device. FIG. 3 is a top view for explaining a partial configuration of the transmitter. FIG. 4 is a top view for explaining a partial configuration of the automatic door device.

  As shown in FIG. 1, an automatic door device 1 according to the present embodiment includes a frame portion 2 attached to an opening that communicates the inside and outside of a building, and a plate-like door 3 that is disposed in the frame portion 2 so as to freely advance and retract. And a forward / backward moving mechanism 4 for moving the door 3 forward and backward.

  The advancing / retreating moving mechanism 4 detects an opening / closing drive unit 5 that opens and closes the door 3, and a detection unit 8 that detects a moving body that enters a predetermined region 6 near the door 3 and issues an opening instruction signal 7 (see FIG. 6). A control unit 9 that controls the opening / closing drive unit 5 based on the opening instruction signal 7 from the detection unit 8, a receiver 11 that detects a predetermined signal 25 (see FIG. 6) emitted from the transmitter 10, and a receiver. 11 prohibits the control based on the opening instruction signal 7 while the predetermined signal 25 is being received, and temporarily opens the opening / closing drive unit by disabling the prohibiting means 12 based on a predetermined operation by the operator. And a release means 13 for controlling 5.

  The opening / closing drive unit 5 is connected to each of the well-known drive mechanism 14 including an electric motor stored in the frame 2 and the drive mechanism 14 and the door 3 to generate power generated by the drive mechanism 14 in a straight line of the door 3. A coupling mechanism (not shown) that converts to motion and a position sensor 17 that measures the relative position of the door 3 and the frame 2 are provided. The opening / closing drive unit 5 is electrically connected to the control unit 9 and its operation is controlled.

  As shown in FIGS. 1 and 2, the detection unit 8 is a light composed of a light emitting unit that irradiates a light beam L from the frame unit 2 toward a predetermined region 6 and a light receiving unit that receives the light beam reflected by the predetermined region 6. A sensor 15 is provided. The optical sensor 15 is electrically connected to the control unit 9. The optical sensor 15 detects a change in reflection of the light beam L by a moving body that enters the space X from the light emitting unit to the predetermined region 6 and transmits an opening instruction signal 7 to the control unit. .

  As shown in FIG. 3, the transmitter 10 is carried by an infant or the like to be prohibited from passing the automatic door device 1. The transmitter 10 includes a power source 21, a radio wave transmission circuit 22 that generates a predetermined signal, and an antenna 23 that transmits a predetermined signal inside the housing 16. Further, the transmitter 10 transmits a predetermined signal radially around the antenna 23, and the distance that the arrival distance reaches from the edge Y1 of the space Y wider than the space X shown in FIG. The output is adjusted and set so as not to injure the human body.

  As shown in FIG. 2, the receiver 11 is arranged in the frame portion 2 and receives a predetermined signal 25 emitted from the transmitter 10. The receiver 11 is electrically connected to the control unit 9, and transmits an opening prohibition signal I to the control unit 9 based on the presence or absence of a predetermined signal 25. (See Figure 6)

  As shown in FIGS. 2 and 4, the receiver 11 has directivity, and receives a predetermined signal 25 emitted from a range of a horizontal angle of 180 degrees around the installation position of the receiver 11. In addition to the adjustment of the output of the transmitter 10, the sensitivity is adjusted so that a predetermined signal 25 emitted from the transmitter 10 in the space Y covering at least the movable range of the door 3 can be detected.

  Further, as shown in FIG. 4, the receiver 11 is disposed on the surface of the one area A side of the door, and only the area A among the plurality of areas A and B partitioned by the door 3 is the reception range. Further, in the present embodiment, a sensor having an appropriate configuration (not shown) is provided on the region B side, and a signal for driving the opening / closing drive unit 5 in response to a person and an object approaching the door 3 from the region B is generated. It is designed to open and close.

  As shown in FIGS. 1 and 2, the release means 13 includes an operation unit 18 attached to the surface of the door 3 on the region A side, and the operation unit 18 is connected to the control unit 9. The operation unit 18 includes a push button type contact sensor 20 that detects a pressing operation by the operator, and the contact sensor 20 is adjusted and fixed so that the contact sensor 20 has a height that does not contact the body of the infant C. The contact sensor 20 issues a release signal R in response to the pressing operation by the operator, and the release signal R is transmitted to the control unit 9 as a radio signal.

Next, the movement control of the door 3 of the automatic door device 1 having the above configuration will be described in detail with reference to FIG. FIG. 5 is a graph for explaining the relationship between the movement position and the movement speed of the door 3 of the automatic door device 1.
The control unit 9 transmits different drive signals to the opening / closing drive unit 5 to change the drive speed of the door 3. The door 3 reciprocates between a position 30 and a position 35. First, when the door 3 is stopped in a completely closed state, the end of the door 3 is located at the position 30 and the door speed is controlled to be zero.

  Subsequently, when the door 3 starts to open, the door speed is accelerated to a predetermined opening high speed 26. The door 3 is controlled to be accelerated from position 30 to position 31 and reach the opening high speed 26 at position 31. When the door 3 reaches the position 31, the speed of the door 3 is controlled to be constant at the opening high speed 26 and moved to the position 32. When the door 3 reaches the position 32, the speed of the door 3 is controlled to be reduced. The door 3 is driven to decelerate from the position 32 to the position 33 and is controlled so as to reach an opening fine speed 27 that is lower than the opening high speed 26 at the position 33. When the door 3 reaches the position 33, the speed of the door 3 is controlled to be constant at the opening slow speed 27 and moved to the position 34. When the door 3 reaches the position 34, the door 3 is further decelerated and controlled so that the speed of the door 3 becomes zero at the position 35 where the door 3 is completely opened.

  Subsequently, when the closing drive is started from the state where the door 3 is completely opened, the speed of the door 3 is accelerated to a predetermined closing high speed 28. The door 3 is controlled to be accelerated from a position 35 to a position 36 and reach a closing high speed 28 at the position 36. When the door 3 reaches the position 36, the speed of the door 3 is controlled to be constant at the closing high speed 28 and moved to the position 37. When the door 3 reaches the position 37, the speed of the door 3 is controlled to be reduced. The door 3 is driven to decelerate from the position 37 to the position 38 and is controlled so as to reach a closing fine speed 29 lower than the closing high speed 28 at the position 38. When the door 3 reaches the position 38, the speed of the door 3 is controlled to be constant at the closing fine speed 29 and moved to the position 39. When the door 3 reaches the position 39, the door 3 is further decelerated and controlled so that the speed of the door 3 becomes zero at the position 30 where the door 3 is completely closed.

  Further, in the control unit 9, the movement position of the door 3 is divided into a plurality of sections and controlled based on the position of the door 3. Specifically, an open acceleration section 40 between the position 30 and the position 31, an open high speed section 41 between the position 31 and the position 32, an open high speed deceleration section 42 between the position 32 and the position 33, and the position 33 and the position. 34 between the position 34 and the position 35, the open end stop section 44 between the position 34 and the position 35, the closing acceleration section 45 between the position 35 and the position 36, and the closing high speed between the position 36 and the position 37. Between the section 46, the position 37 and the position 38 is a closed high speed deceleration section 47, between the position 38 and the position 39 is a closed deceleration section 48, and between the position 39 and the position 30 is a closed end stop section 49. .

  The door 3 is driven to open at an arbitrary position between the position 30 and the position 35 in response to the input of the opening instruction signal 7. Transmission / reception of signals related to opening / closing driving of the door 3 will be described later.

Next, transmission and reception of signals of the automatic door device 1 having the above-described configuration will be described in detail with reference to FIG. FIG. 6 is a block diagram showing the flow of signals in the control unit 9 of the automatic door device 1.
All signals transmitted from the detection unit 8, the receiver 11, and the release means 13 provided in the automatic door device 1 are received by the control unit 9. The control unit 9 transmits a drive signal M for controlling the opening / closing operation of the door 3 to the opening / closing drive unit 5 based on these signals.

Next, the flow of opening and closing the door 3 of the automatic door device 1 will be described in detail with reference to the flowcharts of FIGS.
First, when the automatic door device 1 is activated, the child guard door control S10 shown in FIG. 7 is started. When the child guard door control S10 is started, a conditional branch for invoking each process for issuing the drive signal M to the opening / closing drive unit 5 is started and the process is determined.

  This conditional branch includes a branching step S13 for calling the door closed end stop process S30, a branching step S14 for calling the door open end process S40, and a branching step S15 for calling the door open end stopped process S50.

  When the automatic door device 1 is activated, it is not in any state of the door closing end stop processing S30, the door opening end processing S40, and the door open end stop processing S50, so NO in all the conditional branches of the branching steps S13, S14, and S15. Is selected, and the process is determined in the door closing process S20.

  As shown in FIG. 8, the door closing process S <b> 20 is a process for closing the door 3, and takes charge of a process from when the door 3 is started to be closed until the door 3 is closed. When the door closing process S20 is started, it is determined whether or not the door 3 is stopped in the closed state based on the position information from the position sensor 17 that measures the movement position of the door 3 (process S21). .

  When it is determined that the door 3 is stopped in a closed state (YES), a driving signal for setting the moving speed of the door 3 to 0 is transmitted to the opening / closing drive unit 5 and then a door closing end stop processing S30 described later. (Processing S27). When it is determined that the door 3 is closed and not stopped (NO), it is subsequently determined whether or not the opening instruction signal 7 is input (processing S22).

  The opening instruction signal 7 is a signal emitted from the optical sensor 15 when a person such as the person P1 or the infant C or other moving body enters the space X. If it is determined that the opening instruction signal 7 has been received (YES), a drive signal for setting the door speed to 0 is transmitted to the opening / closing drive unit 5 that is in the closed drive, and then the door opening process S40 described later is performed. The process proceeds (process S26). When it is determined that the opening instruction signal 7 has not been received (NO), it is subsequently determined whether or not the position of the door 3 is in the closed high speed section 46 (processing S23).

  When it is determined that the position of the door 3 is in the closed high speed section 46 (YES), a drive signal for setting the speed of the door 3 to the closed high speed 28 is transmitted to the opening / closing drive unit 5 and then to the child guard door control S10. Return (processing S24). On the other hand, if it is determined that the position of the door 3 is not in the closed high speed section 46 (NO), that is, the position of the door 3 is in the closed high speed deceleration section 47 or the closed fine speed section 48, the speed of the door 3 is reduced. After transmitting a drive signal for speed 29 to the opening / closing drive unit 5, the process returns to the child guard door control S10 (process S25).

  After returning from the process S24 and the process S25 to the child guard door control S10, NO is selected in all of the branching steps S13, S14, and S15, and the door closing process S20 is called again. As a result, the door closing process S20 is repeated until the door 3 is completely closed and the process proceeds to the door closing end stop process S30 or until the door opening process signal S7 is received and the process proceeds to the door opening process S40.

  As shown in FIG. 9, the door closed end stop process S <b> 30 is a process in a state where the door 3 is in the closed state and the moving speed of the door 3 is 0. When the door closing end stop process S30 is started, the control unit determines whether or not the release signal R is received (process S31). If it is determined that the release signal R has been received (YES), the process proceeds to the door opening process S40 regardless of the presence or absence of the opening prohibition signal I, and the door 3 is controlled to be forcibly opened. On the other hand, if it is determined that the release signal R has not been received (NO), it is subsequently determined whether the release instruction signal 7 has been received (step S32). When it is determined that the opening instruction signal 7 has been received (YES), the opening prohibition signal I issued from the receiver 11 is canceled by receiving the predetermined signal 25 from the transmitter 10 subsequently. (Processing S33).

  If the opening prohibition signal I has been canceled (YES), the process proceeds to a door opening process S40 described later in order to drive the door 3 to open (process S35). When it is determined that the release instruction signal 7 is not received in the process S32 (NO), or the release instruction signal 7 is received in the process S32 (YES) and the release prohibition signal I is not canceled (NO) in the process S33 Transmits a drive signal for setting the speed of the door 3 to 0 to maintain the door 3 stopped, and then returns to the child guard door control S10 (step S34).

  After returning from the process S34 to the child guard door control S10, the door closing end stop process S30 is called again by the process from the branching process S13, so that the opening instruction signal 7 is received and the opening prohibition signal I is canceled and the door is released. The door closing end stop process S30 is repeated until the process proceeds to the opening process S40.

  As shown in FIG. 10, the door opening process S <b> 40 is a process for driving the door 3 to open. When the door opening process S40 is started, it is determined whether or not the position of the door 3 is in the opening stop section 44 (process S41). When it is determined that the position of the door 3 is in the opening stop section (YES), a control signal for setting the speed of the door 3 to 0 is transmitted to the opening / closing drive unit 5 to control the door 3 to stop at the position 35. After that, the process proceeds to the door open end stop process S50 (process S45). On the other hand, when it is determined that the position of the door 3 is not in the opening stop section 44 (NO), it is determined whether or not the position of the door 3 is in the opening high speed section 41 (processing S42).

  When it is determined that the position of the door 3 is in the opening high speed section 41 (YES), a drive signal for setting the speed of the door 3 to the opening high speed 26 is transmitted to the opening / closing drive unit 5 to the child guard door control S10. Return (processing S44). When it is determined that the position of the door 3 is not in the open high speed section 41 (NO), that is, when the door 3 is between the position 32 and the position 35, the drive of the door 3 is set to the opening fine speed 27. A signal is transmitted to the opening / closing drive unit to return to the child guard door control (step S43).

  After returning to the child guard door control S10 from the process S43 and the process S44, the door opening process S40 is called again by the process from the branching process S14, so that the door 3 is completely released and the door open end stop process S50 is performed. The door opening process S40 is repeated until the transition.

  As shown in FIG. 11, the door open end stop process S50 is a process in a state in which the door 3 is fully opened and the speed of the door 3 is zero. When the door open end stop process S50 is started, it is first determined whether or not the opening instruction signal 7 has been received (process S51). When it is determined that the opening instruction signal 7 has been received (YES), in order to maintain the door 3 in the opened state, a drive signal for setting the door speed to 0 is transmitted to the opening / closing drive unit 5 and the door 3 The timer for counting the opening time is reset and the process returns to the child guard door control S10 (process S55).

  On the other hand, if it is determined that the opening instruction signal 7 has not been received (NO), whether or not the opening holding time set in advance with reference to a timer for counting the opening time of the door 3 has been reached is determined. Is determined (step S52). If the opening time of the door 3 has reached the opening holding time (YES), the process proceeds to door closing process S20 in order to drive the door 3 to close (process S54). When it is determined that the opening time of the door 3 has not reached the opening holding time (NO), a drive signal for setting the speed of the door 3 to 0 is transmitted to the opening / closing drive unit in order to keep the door 3 open. Thereafter, the process returns to the child guard door control S10 (process S53).

  After returning from the process S53 and the process S55 to the child guard door control S10, the door open end stop process S50 is called again by the process from the branching process S15. Until this is done, the door open end stop process S50 is repeated.

The operation of the automatic door device 1 having the above-described configuration will be described with reference to FIGS. 12 to 14 focusing on the relationship with a moving object such as a person or an object approaching the door 3.
First, operation | movement of the automatic door apparatus 1 with respect to the person P1 who does not carry the transmitter 10 is demonstrated with reference to FIG. The person P1 approaches the door 3 from the area A side of the closed automatic door apparatus 1. When the human P1 is outside the space Y, the automatic door device 1 repeatedly executes the door closed end stop process S30.

  The human P1 further approaches the door 3, enters the space Y, and then approaches the space X. Since the human P1 does not have the transmitter 10, the receiver 11 does not receive the predetermined signal 25. Therefore, the opening prohibition signal I is not issued. When the person P1 further approaches the door 3 and the person P1 enters the space X, the opening instruction signal 7 is transmitted from the optical sensor 15 to the control unit 9, whereby the door opening process S40 is executed and the door 3 is opened. Driven. In this way, the human P1 can pass through the door 3.

Next, operation | movement of the automatic door apparatus 1 with respect to the infant C carrying the transmitter 10 is demonstrated with reference to FIG.
When the infant C carrying the transmitter 10 is outside the space Y, the automatic door device 1 repeatedly executes the door closed end stop process S30 as described above. When the infant C carrying the transmitter 10 approaches the door 3 and enters the space Y, a predetermined signal 25 emitted from the transmitter 10 is detected by the receiver 11.

  Then, the opening prohibition signal I is transmitted from the receiver 11 to the control unit 9. When the infant C further approaches the door 3 and enters the space X, the optical sensor 15 detects the intrusion of the moving body into the space X, and transmits the opening instruction signal 7 to the control unit 9, and the process S32 is (YES). It is determined.

  Subsequently, it is determined whether or not the release prohibition signal I has been canceled in the process S53, but since the infant C cannot press the contact sensor for canceling the release prohibition signal I, it is determined as NO in the process S33. Thus, the door 3 is kept closed. As a result, the infant C carrying the transmitter 10 cannot pass through the door 3.

Next, the operation of the automatic door device 1 for the infant C carrying the transmitter 10 and its guardian P2 will be described with reference to FIG.
As described above, the automatic door device 1 of the present embodiment has a structure in which the infant C carrying the transmitter 10 cannot pass through the door 3 alone. At this time, a guardian P2 who supervises the infant C, such as a guardian of the infant C, may pass the infant C, or the infant C and the guardian P2 may pass the door 3 at the same time.

  The guardian P2 is also the same as the above-described human P1 in that the transmitter 10 is not carried. Further, while the infant C carrying the transmitter 10 is present in the space Y, the opening prohibition signal I is issued from the receiver 11 to the control unit 9 by the predetermined signal 25 emitted from the transmitter 10. For this reason, when the guardian P2 and the infant C enter the space X, the door 3 is not opened.

  At this time, the guardian P2 makes the contact sensor 20 contact a part of the human body (for example, a finger). Then, the contact sensor 20 senses the operation of the push button, transmits a release signal R to the control unit 9, and the release prohibition signal I is released. Since both the reception of the opening instruction signal 7 and the cancellation of the opening prohibition signal I occur in the control unit 9, (YES) is selected in both the processing S32 and the processing S33, and the process proceeds to the door opening processing S40 and the door 3 Is released. As a result, the guardian P2 and the infant C can pass through the door 3.

  As described above, according to the automatic door device 1 according to the present embodiment, since the door 3 is stopped at the closed position while the transmitter 10 is in the space Y, a child such as an infant is alone. Passing through the door can be prevented.

  Moreover, since the guardian P2 can release the prohibiting means 12 and drive the door 3 by providing the releasing means 13 by the contact sensor 20, the infant and the parent pass together as necessary. The door can be opened and the infant C can pass safely.

  Since the door 3 is driven to open by the optical sensor 15 while the transmitter 10 is not in the space Y, the operation for driving the door 3 is simplified.

(Second embodiment)
Next, an automatic door device according to a second embodiment of the present invention will be described with reference to FIGS. 15 to 16 are flowcharts for explaining the operation of the automatic door device of the second embodiment. FIG. 17 is a graph for explaining the operation of the door of the automatic door device according to the second embodiment. In each embodiment described below, portions having the same configuration as those of the automatic door device 1 according to the first embodiment described above are denoted by the same reference numerals and description thereof is omitted.

The automatic door device 100 of this embodiment is different from that of the first embodiment in that it includes speed switching means 113 that changes the opening / closing speed of the door 3 in the opening / closing operation of the door 3.
The speed switching means 113 is signal processing in the control unit 9, and the automatic door device 100 of the second embodiment is based on the opening prohibition signal I from the receiver 11 and the position information of the door 3 from the position sensor 17. 3, the door closing process S20 and the door opening process S40 each have different processing steps from the first embodiment.

  As shown in FIG. 15, the door closing process S20 according to the second embodiment is determined as YES in the process S23, and then it is determined whether or not the opening prohibition signal I is received by the control unit 9 (process S28). ). If it is determined that the opening prohibition signal I has been received (YES), the door 3 is driven by switching the speed of the door 3 to the opening switching speed 28A (see FIG. 17) lower than the closing high speed 28. A drive signal is transmitted to the opening / closing drive part 5, and it returns to child guard door control (process S29). On the other hand, if it is determined that the opening prohibition signal I has not been received (NO), a driving signal for setting the moving speed of the door 3 to the closing high speed 28 is transmitted to the opening / closing driving unit 5 as in the first embodiment. And it returns to child guard door control S10 (process S25).

  As shown in FIG. 16, the door opening process S40 of the second embodiment determines whether or not the opening prohibition signal I is received by the control unit 9 after it is determined YES in the process S42 ( In step S46), when it is determined that the opening prohibition signal I has been received (YES), the speed of the door 3 is switched to the opening switching speed 26A (see FIG. 17) which is lower than the opening high speed 26, and the door. 3 is transmitted to the opening / closing drive unit 5 to return to the child guard door control (step S47). On the other hand, if it is determined that the opening prohibition signal I has not been received (NO), a drive signal for setting the moving speed of the door 3 to the opening high speed 26 is transmitted to the opening / closing drive unit 5 as in the first embodiment. And it returns to child guard door control S10 (process S44).

  In the second embodiment, when the presence of the transmitter 10 is detected by the receiver while the door 3 is completely closed, the opening of the door 3 can be prohibited as in the first embodiment. At the same time, when the transmitter enters the space Y when the door 3 is being opened and closed, the moving speed of the door 3 is reduced. Even if it is such a structure, there can exist the effect of this invention. Furthermore, in this embodiment, it is possible to prevent injury when an infant or the like collides with the moving door 3.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
For example, in the present embodiment, the transmitter 10 is carried by the infant C. However, the transmitter 10 is not limited to this and can be used for infants. In this case, the transmitter 10 can be configured not only to be carried by an infant but also to be fixed to a moving body such as a stroller on which the infant is boarded. Also in this case, when the baby or the moving body approaches the automatic door device 1, the same effect as in the present embodiment can be obtained.

  Moreover, the shape of the casing 16 of the transmitter 10 can employ an appropriate configuration according to the usage pattern, particularly a configuration that is considered to be used by an infant. For example, it is possible to prevent injuries when colliding with a human body by using a substantially spherical shape having no protrusions. Alternatively, by adopting a soft material on the surface, it is possible to prevent injuries when colliding with the human body and to absorb the shock applied to the transmitter 10, thereby preventing a failure of the transmitter 10. Further, the casing 16 may be provided with a fixing portion that can fix the transmitter 10 to a part of the body or clothes of the infant C. In this case, loss of the transmitter 10 can be prevented.

  Further, in the present embodiment, the transmitter 10 employs a configuration in which the predetermined signal 25 is transmitted with a set constant output. However, the present invention is not limited to this, and the predetermined signal 25 is emitted only while entering the space Y. A configuration in which the predetermined signal 25 is not output when outside the space Y is also possible. In this case, the burden on the power source 21 can be reduced to save power, and the influence on the human body due to the electromagnetic waves emitted from the transmitter 10 can be suppressed. Here, as a configuration for detecting that the transmitter 10 has entered the space Y, a configuration in which the receiver 11 transmits the signal S2 reaching the predetermined space Y1 and the transmitter 10 receives the signal S2 is adopted. You can also.

  In the present embodiment, the contact sensor 20 is disposed at a position where the body of the infant C does not contact, but the height of the infant to be prohibited from passing depending on the situation in which the automatic door device 1 of the present invention is used. Appropriate design changes can be made to correspond to It is also possible to adopt a variable structure that positions the contact sensor by changing the position in the height direction.

  Further, in the present embodiment, the touch sensor 20 is a push button type wireless type touch sensor, but is not limited to this, and the touch sensor 20 is not limited to this and is appropriately positioned to detect an operation by the operator placed at a position where the body of the infant C does not touch. An input device such as a sensor can be employed. For example, the contact sensor 20 may employ a wired system that is electrically connected to the control unit 9. In addition, for example, a touch switch using static electricity for input can be adopted. In this case, the release means does not operate even if the infant touches the touch switch via a long stick or the like. Can be prevented from opening and closing.

  Further, in the automatic door device 1 of the first embodiment of the present invention, the door closed end stop process S30 includes a process S31 that shifts to the door open process S40 in order to forcibly open the door 3 by the release signal R. Although not limited to this, for example, as shown in the flowchart of FIG. 18, the process S31 is not provided, and it is determined whether or not the opening prohibition signal I is received in the control unit 9 instead of the process S32. Even when the process S36 for determining whether the release prohibition signal I is canceled by the release signal R, the same effect as the present invention can be obtained.
