By attaching the mover block 3 to the sliding door body 10 and using the Kamoi 31 containing the stator block 2, a sliding door driven by a power source can be constructed.
Can be formed to have the same dimensions as a manual sliding door, so that the replacement of the manual door 31 allows the manual sliding door to be replaced with an electric sliding door.

As described above, the mover block 2 includes the plurality of coils 4 and the substrate 41 on which the Hall IC 6 is mounted. In order for the mover block 3 to travel with respect to the stator block 2, it is necessary to control the timing of energizing the coil 4 based on the output of the Hall IC 6. Therefore, a controller 7 is provided to control the timing of energizing the coil 4. The controller 7 is housed in the housing 61 as shown in FIGS. 11 and 12, and forms a concave groove 37 on one side in the width direction of the wide portion of the gate 31 as shown in FIGS. 4 and 5. Is stored in a non-existent area. That is, the controller 7 is arranged near the center in the width direction at the opening of the building. In addition, the lower surface of the housing 61 of the controller 7 is aligned with the lower surfaces of other parts of the Kamoi 31. By arranging the housing 61 at such a position, the controller 7 is provided at a position where it is easy to work when operating and maintaining the controller 7.

The controller 7 has a configuration shown in FIG.

The output control unit 70 includes, in addition to the Hall IC 6 described above, an output of a human sensor 75 that detects the presence or absence of a person using a heat ray radiated from a human body, and a receiving unit 76a that receives a wireless signal using infrared rays as a transmission medium. ,
The output of 76b is input. The output control unit 70 includes a microcomputer as a main component, and is supplied with power in which the output voltage of the rectifying and smoothing unit 73 is stabilized by the control power supply unit 77.

The above-mentioned motion sensor 75 is a passive motion sensor using a pyroelectric infrared sensor, and receives a heat ray radiated from a person, and when a heat dose changes by a predetermined amount or more. To change the output. This type of motion sensor is passive and does not require the function of irradiating the object with infrared rays, so its configuration is simple, and it does not require cooling or the like, and is inexpensive, space-saving, and easy to handle. . The detection area of this type of motion sensor 75 can be easily set by optically controlling the visual field, and the detection area can be set in a well-balanced manner around the opening. Also, one window 62 through which infrared light passes is connected to the controller 7.

The output control unit 70 moves the sliding door main body 10 so as to open the opening while the presence of a person is detected by the human sensor 75, and after the presence of the person is no longer detected, the output control unit 70 opens the opening. The sliding door main body 10 is configured to move so as to close the portion. Therefore, the timing of closing the sliding door main body 10 can be set from the time when the presence of the person is no longer detected by the human sensor 75, and the sliding door main body 10 can be set after a certain period of time limited by the timer after detecting the presence of the person. It is advantageous in that the operation of adjusting the time of the timer is not required as compared with the configuration in which the timer is closed. In addition, since a pyroelectric infrared sensor is used as the human sensor 75, adjustment work of a detection area is not required as compared with an ultrasonic human sensor or the like, so that installation work is facilitated.

The output controller 70 controls the sliding door main body 1 according to the content of the wireless signal received by the receiver 76a.
0 is controlled. That is, the opening and closing of the sliding door body 10 can be instructed by a wireless signal. The receiving unit 76b not housed in the housing 61 functions equivalently to the receiving unit 76a, and the output control unit 70 controls the opening and closing of the sliding door body 10 also by the wireless signal received by the receiving unit 76b. In addition, on the lower surface of the housing 61 of the controller 7, indicator lights 66a and 66b made of light emitting diodes are arranged near the window 62 and the light receiving window 64.

The housing 6 sandwiches the traveling rail 36 on which the sliding door body 10 travels.
1 is arranged on the opposite side. In short, the receiving units 76a and 76b are arranged on both sides of the sliding door body 10. As described above, by providing the receiving portions 76a and 76b on both sides of the sliding door body 10, it is possible to instruct the opening and closing of the sliding door body 10 by a wireless signal from either the front or back of the sliding door body 10. The area where the remote control device for transmitting the signal can be used is widened.

By the way, lids 61a and 61b are detachably attached to both ends in the longitudinal direction of the casing 61 of the controller 7, respectively. One lid 61a covers a connection portion connected to the stator unit 2, and a signal connector 78 and a power supply connector 79 are housed in this portion. 7, a connection line 81 is connected to the connector 78, and the connection line 81 is connected to the connector 45a as shown in FIG. Further, as shown in FIG.

When the lid 61b is removed, the operation hole 77b for operating the wire insertion port 77a and the release button (not shown) is exposed. Here, the quick-connecting terminal structure is a locking spring (not shown) made of a leaf spring.
The connection and removal of the wire are performed by simply inserting the wire from the wire insertion port 77a, and the connection and removal of the wire are performed by the locking spring. Also, if a tool such as the tip of a flathead screwdriver is inserted into the operation hole 77b and the release button is pressed, the release button bends the locking spring so that the wire holding by the locking spring can be released. It is configured.

However, at the time of construction, if a power supply wire is inserted into the wire insertion port 77a and the cover 61b is attached, the wire is not exposed, and only the operation part of the power switch 72 is operated.
