It is arranged in a state of being in contact with the outer peripheral side surface of the arc of the guide body 10 provided at the upper end edge portion, and the left and right end edges are provided at each end edge portion of the guide body 10 on the door end side and the door end side. It is attached to and supported by the guide body 10 via the support member 10a. Then, as will be described later, the switch 7 is driven in the forward and reverse directions based on the drive command from the control unit 8, and the sprocket 7a is rotated, so that the transmission belt 9 moves in the left-right direction, whereby the doorway 4 enters and exits. It is configured to open and close with respect to E.

Reference numeral 11 denotes a non-contact type switch device attached to the inner side surface of the booth of the side panel body 3 on the door end side, and the switch device 11 is a vertically long flat plate applied to the inner side surface (indoor side surface) of the side panel body 3. A base material 12 having a rectangular shape, a pair of brackets 13 arranged so as to face each other with an interval Z above and below the base material 12, and light emitters 14 and 14a provided on the brackets 13 are provided. In this embodiment, the switch device 11 is provided on the inner side surface portion close to the doorway E of the side panel body 3 on the door end side.
In the present embodiment, the light emitting and receiving devices 14 and 14a employ not the light source in the visible region (visible light) but the infrared light outside the visible region as the light source, but the light projector 14 is directed downward so as to emit light upward. The receiver 14a is provided on the bracket 13 on the side and is provided on the bracket 13 on the upper side so that the light receiver 14a receives light from the lower side. The sensitivity (accuracy) of the light received by the light receiver 14a is considered so as not to be affected by the light emitted from above such as the lighting provided on the ceiling as much as possible.

Further, the switch device 11 is arranged at the inner side surface portion close to the entrance / exit E of the side panel body 3 on the door end side, and the arrangement position is specifically the entrance / exit E to the toilet seat T. It is a part that the hand does not reach (cannot reach) when an adult user with an average physique sitting facing the part side reaches, for example, the distance Y from the front end edge of the toilet seat T is 650 mm or more forward. It is arranged in the (doorway E side) part and the part where the height U from the floor surface F is 1200 mm or more, and by doing so, the user sitting on the toilet seat T. It is considered that the switch device 11 is not inadvertently activated by the hand extended by the hand getting into the space between the brackets 13.
In the present embodiment, infrared rays, which are one of the light rays, are selected as the aerial transmission wave, and the switch detection is performed by blocking the optical axis of the light emitting and receiving by the light emitting and receiving devices 14 and 14a. Of course, it is not limited to this, and when the aerial transmission wave is a ray, the ray is not limited to infrared rays, but is visible rays, far infrared rays outside the visible region like infrared rays, and further laser beams. A ray (light source) as an appropriate transmission wave to be transmitted in the air can be adopted, and as an aerial transmission wave other than the ray, a normally known transmission wave such as a sound wave (including an ultrasonic wave) or a microwave can be adopted. Of course, it may be.
When the aerial transmission wave is the infrared rays of the present embodiment, the transmitter / receiver serving as the light emitters 14 and 14a is a transmission wave (light beam) transmitted (flooded) from the transmitter (floodlight 14). ) Is directly received by a receiver (receiver 14a) provided on the opposite side, but the present invention is not limited to such a light-emitting type, and the transmitter / receiver is combined with a pair of brackets. As long as the detection range is provided within the locus connecting the outer peripheral edges of the brackets facing each other, the configuration is not limited to the one in which the transmitter and the receiver are provided in each bracket, and the transmitter / receiver is not limited to the one in which the transmitter and the receiver are provided in each bracket. Is arranged in the same bracket 13, and the transmitted wave transmitted from the transmitter hits the bracket 13 arranged oppositely and is reflected, and the reflected reflected wave (reflected light) is received by the receiver. The present invention can be configured even if it is a reflective type that activates the switch by detecting changes such as no reception of reflected waves, disturbance due to the reflected waves hitting an obstacle, and different reflection times. Can be carried out.
Incidentally, the state in which the detection range falls within the locus connecting the outer peripheral edges of the brackets facing each other means that the transmitted wave is, for example, a sound wave or a microwave, and it is detected that the receiver receives the reflected transmitted wave. If so, it means that the reception of the transmission wave reflected from the outside of the locus connecting the outer peripheral edges of the bracket is not included, and in this case, the determination of not including is the time from transmission to reception. It is known that it can be done by recognizing the distance of the reflector position by the measurement of.

The base material 12 constituting the switch device 11 is attached to the side panel body 3 via the screw 12a. Further, the upper and lower brackets 13 are configured in an isosceles triangular prism shape whose vertices are chamfered in an arc shape in a plan view, and a bottom piece portion 13a corresponding to the base of the isosceles triangle is attached to the side panel body 3. In a state of being in contact with the base material 12, the bracket 13 is attached to the base material 12 via a screw 13c screwed from the side piece portion 13b corresponding to the isosceles side, whereby the bracket 13 is attached to the side panel body 3. It is attached so as to project from the inner side surface toward the inside of the booth 1 in the left-right direction.
In this way, the bracket 13 is formed in a triangular shape (sharp shape) that becomes narrower toward the tip side, so that when a load such as a handbag is hung on the bracket 13, the bracket 13 is moved to the tip side of the hung baggage. It is designed to induce movement to make it difficult to hang luggage, so that the user can give up hanging luggage on the bracket 13.
In order to further enhance such a consideration effect, the upper surface of the bracket 13 may be inclined so as to be lower toward the tip side.

Further, in the upper and lower brackets 13, the distance Z between the upper and lower facing surfaces of the brackets 13 facing each other is smaller than the width of the back of the hand opened by an adult of the average physique, but wider than the thickness of the back of the open hand ( For example, it is set to 70 mm). Since the facing distance Z is set in this way, when the user in the booth 1 stumbles and accidentally pokes the open hand into the bracket 13 part, the open hand is between the upper and lower brackets 13. It is considered to be able to effectively avoid entering and activating the switch, but since the facing interval Z is set to be larger than the thickness of the back of the open hand, it is intended for the user to activate the switch. It is designed so as not to prevent the hand from being inserted between the upper and lower brackets 13.

Moreover, the light emitting and receiving devices 14 and 14a of the switch device 11 configured in this way are provided so as to face each other at the tip portion of the bracket 13, and by being attached in this way, light is received from the light receiving device 14 from the light emitting and receiving device 14. The optical axis L leading to the vessel 14a is set to fit in the locus connecting the outer peripheral edges of the upper and lower brackets 13 (do not protrude from the locus), and by blocking this optical axis L by hand, the hand becomes a blocker. It is set to activate the switch.
The blocking of the optical axis L is also performed by inserting a hand into the gap Z between the upper and lower brackets 13 facing each other, but the light emitting and receiving devices 14 and 14a are provided at the tip portion of the protruding bracket 13. As a result, the position is set to an appropriate protrusion from the inner surface of the side panel body 3 (the distance from the inner side surface of the side panel body 3 to the axis of the optical axis L is set to, for example, 45 mm). When a hand is inserted between the upper and lower brackets 13 to block the optical axis L, it is not necessary to insert the inserted hand deeply until it comes into contact with the base material 12, and the inserted hand may come into contact with the base material 12. It is a non-contact type that is designed so that the switch can be activated by inserting it halfway.

Further, the insertion direction of the blocking object such as a hand between the upper and lower brackets 13 is not only from the left-right direction side where the bracket 13 protrudes from the side panel body 3 (the front side in the protruding direction of the bracket 13), but also in FIG. As shown in a plan view, a wide-angle direction that exceeds an angle of 180 degrees along the inner side surface of the side panel body 3 to which the bracket 13 is attached and can be inserted from a side that is biased toward the side panel body 3. Insertion from is allowed, which allows the switch to be activated from a wide angle direction. Further, in this case, the insertion of the barrier from the wide angle range allows three-dimensional insertion not only from the horizontal direction but also from the vertically inclined direction, so that high operability is exhibited.
In the present embodiment, stickers 17 and 18 describing necessary items such as switch operation and precautions are affixed to the space between the upper and lower brackets 13 of the base material 12 and to the side in the front-rear direction of the base material 12. It is designed to alert the user.

Next, the drive control by the control unit 8 of the switch 7 will be described. As shown in the block circuit diagram of FIG. 10, in addition to the switch device 11 as an input side, a fully open detection sensor 15 and a fully closed detection sensor 16 are connected to the control unit 8, and a switch 7 is connected as an output side. However, as the fully closed / fully open detection sensors 15 and 16, the sensor of the present embodiment is of the encoder type built in the switch 7, and the drive shaft for rotating the sprocket 7a (FIG. Based on the amount of rotation (not shown), it is possible to determine that the door body 4 is in the fully closed position or the fully open position. Of course, the fully closed and fully open detection sensors 15 and 16 are not limited to those of the encoder type, and for example, the limit switch detects a state in which the door body 4 is in the fully closed or fully open posture. Position detection such as, load detection of the switch 7 that increases when the door body 4 is in the fully closed or fully open position and the door body 4 is subject to movement restrictions, and an electric motor provided in the switch 7. Various open / close position detection means such as those capable of detecting the position of the fully closed posture and the fully open posture based on the drive position detection executed in the drive control when the drive control is performed by pulse control of a servomotor or the like. Such a thing can be appropriately selected if necessary.

As shown in FIG. 11, the control unit 8 executes the opening / closing control system (open / close control routine) of the door body 4 with the initial settings such as when the power is turned on. First, in the control unit 8, it is determined whether the door body 4 is in the fully closed posture or the fully open posture based on the signals from the fully open detection sensor 15 and the fully closed detection sensor 16 (S1), and the door body 4 is fully opened. When it is determined to be in the posture, it is determined (recognized) whether the switch device 11 is continuously turned on (whether the optical axis is cut off) during the first predetermined time (for example, 1 second) T1 set in advance. It is done (S2). When it is determined that the switch operation 11 is ON (cutting off the optical axis L) during the first predetermined time, a closing command is output to the switch 7 (S3), and the door body is controlled by the fully closed detection switch 16. When it is determined that 4 is in the fully closed posture (S4), the drive stop command of the switch 7 is output and the timer is started (S5).

On the other hand, when it is determined that the door body 4 is not in the fully open posture, the door body 4 is in the fully closed posture, and in this case, the preset timer time (for example, 30 minutes) T of the timer has elapsed. If it is determined that (S6) has passed, an opening command is output to the opening / closing machine 7 (S7), and if it is determined that the door body 4 is fully opened (S8), the opening / closing machine is used. The drive of 7 is stopped (S9) and the product returns. By the way, when it is judged that the timer time T has passed, it is judged that the closed state of the door body 4 is too long for normal use, and the management room is notified or an alarm is sounded. can do.
Further, when it is determined in the progress determination (S6) of the timer time T that the time has not elapsed (within the timer time T), the switch device continues for the second predetermined time (for example, 2 seconds) T2. When it is determined (S10) that the switch has been turned ON, and if it is determined that the switch has been turned ON, the control (S7) for outputting an open drive command to the switch 7 is set. Then, the opening / closing drive control of the door body 4 is executed.
The open / close control system for the door body 4 described in the present embodiment is a simple description of an example of a control system in a normal state in which the door body 4 is normally opened / closed, and is initially set. Since the description of various control systems necessary for electrically opening and closing the door body 4 at times, in the event of an abnormality such as when the door body 4 is stopped in the middle, or in the event of a failure, is not directly related to the present invention. Omit.

In the present embodiment configured as described above, the optical axis L that scans the switch device 11 provided for electrically opening and closing the door body 4 provided in the toilet booth 1 between the light receiving receivers 14 and 14a by hand or the like. As a result of the non-contact type in which the switch is activated by blocking with the blocking object, the range in which the blocking of the optical axis L by the blocking object such as a hand is within the locus connecting the outer peripheral edges of the pair of brackets 13. In other words, it is done within the range that does not protrude from the bracket 13, avoiding false detection that the switch is activated in response to the proximity of a person or luggage, and ensuring that the operator is conscious of non-contact. Switch can be operated.
Moreover, in this case, since the light emitting and receiving receivers 14 and 14a are provided on the bracket 13 protruding from the side panel body 3, a blocking object such as a hand intrudes between the brackets 13 to block the optical axis L. The operability is excellent because it can be penetrated from a direction of 180 degrees or more along the inner side surface to which the bracket 13 of the side panel body 3 is attached.

Further, the facing distance Z of the pair of brackets 13 is 70 mm, which is narrower than the width of the back of the open hand of an adult of average physique, but is set to be wider than the thickness of the back of the open hand, so that the user in the booth 1 can use it. When a hand that is inadvertently opened when stumbling is hung on the switch device 11, it is possible to effectively prevent the hand from entering between the brackets 13 and activating the switch, while the interval Z is set. Since it is wider than the instep thickness, it does not interfere with the switch operation intended to put a hand between the brackets 13, and the operability is excellent.
In this case, since the pair of brackets 13 are arranged so as to face each other vertically so that the optical axis L faces vertically, the upper bracket 13 when the user puts his / her hand on the bracket when he / she stumbles. As a result, it is possible to more effectively prevent the hand from blocking the optical axis, and the user can put a baggage such as a handbag or clothes on the upper bracket. When it is applied to 13, it is possible to effectively avoid the luggage from shielding the optical axis L, and it is possible to improve the certainty of switch operation.
