Japanese Unexamined Patent Publication No. 7-317471 JP-A-2015-31022

As described above, in a shutter device equipped with a clutch for switching the shutter curtain from the electric type to the manual type and from the manual type to the electric type, this switching is detected when the clutch is switched on or off. If possible, such a shutter device is desired because it can be provided with a function such as being able to confirm whether the shutter device at that time is an electric type or a manual type.

An object of the present invention is to provide an electric / manual switching device for a shutter device that can detect on / off switching of a clutch.

The electric / manual switching device for the shutter device according to the present invention has a take-up shaft for winding and unwinding the shutter curtain in order to open and close the shutter curtain, and an electric motor for rotating the take-up shaft. An opening / closing machine is provided between the take-up shaft and the electric motor, and when the motor is turned on, the driving force of the electric motor is transmitted to the take-up shaft to open and close the shutter curtain electrically. A shutter configured to include a clutch for making the shutter curtain movable and manually opening and closing the shutter curtain by shutting off between the take-up shaft and the electric motor by turning it off. The electric / manual switching device of the device is characterized by including an electric switch for detecting the on / off switching of the clutch.

Therefore, in the electric / manual switching device of the shutter device according to the present invention, the on / off switching of the clutch can be detected by the electric switch, whereby the electric type to the manual type and the manual type to the electric type can be detected. Various functions such as being able to confirm whether the shutter device at that time is an electric type or a manual type can be added to the shutter device that can be switched to the type. The electric switch may be a contact type or a non-contact type. Further, the electric switch may be any one such as a micro switch or a tape switch as long as it can convert the mechanical motion of the clutch into an electric signal.

Then, as an example of various functions that can be given to the shutter device, the display device provided in the shutter device indicates which state the clutch is in, on or off, in other words, electric. It is to display which of the two, manual and manual, is in a state where the shutter curtain can be opened and closed.

In addition, the function of another example is a control device that controls an operation signal from an operation device provided with "open", "close", and "stop" operation buttons in order to move or stop the shutter curtain by electric power. When the disengagement of the clutch is detected by the electric switch in the shutter device in which the control device controls the switch having the electric motor, the control device sends the signal to the control device. The "open" signal, the "closed" signal, and the "stop" signal are invalidated in the control device.

In addition, the function of another example is that instead of invalidating the "open", "closed", and "stop" signals in the control device, the control device to which the "open" signal and the "closed" signal are sent is the electric switch. The above-mentioned operating device indicates that the motor is idled for a predetermined time, for example, one second, and the control device activates a notification means such as an alarm device or a display device to disengage the clutch by voice and / or display. It is to be able to warn the person who operates. In this case, when the "stop" signal is sent to the control device, this control device activates the notification means such as an alarm device and a display device, and the clutch is disengaged by voice and / or display. It may be possible to warn the person operating the above-mentioned operating device that the above.

Further, the function of another example is that when the clutch that has been disengaged is turned on, the electric signal of the electric switch that detects this is sent to the control device, and the control device is provided in the shutter device. The display device is made to display a display for urging the shutter curtain to be opened and moved to the fully opened position by operating the "open" button of the operating device. According to this, regardless of the position where the shutter curtain manually opened / closed and moved when the clutch is disengaged, the operator of the operating device opens the shutter curtain to the fully opened position according to the display of the display device. By moving the shutter open, it is possible to reset the count for the detection means for detecting the position of the shutter curtain at that time by the rotation speed of the electric motor of the opening / closing machine and the rotation speed of the take-up shaft. This makes it possible to set the origin of the count at the fully open position of the shutter curtain.

In the above-mentioned electric / manual switching device for the shutter device according to the present invention, the clutch on / off switching principle may be arbitrary, and one example thereof is a clutch, a drive rotating member on the electric motor side, and the above. It is assumed that the driven rotating member on the take-up shaft side is included, and one of the driven rotating member and the driven rotating member slides and moves in the axial direction with respect to the other rotating member. These rotating members are connected and disconnected, and the clutch can be switched on and off. When the clutch is configured in this way, the electric switch detects that one of the rotating members slides and moves in the axial direction with respect to the other rotating member, and detects switching between on and off of the clutch. It may be the one to do.

In this way, when the electric switch detects that the one rotating member slides in the axial direction with respect to the other rotating member and detects the on / off switching of the clutch, it is electric. The switch may detect the on / off switching of the clutch by directly detecting that the one rotating member slides in the axial direction with respect to the other rotating member, or the clutch may be a switch. When the one has an operating member that operates to slide and move the one rotating member in the axial direction with respect to the other rotating member, an electric switch detects the operation of the operating member. When the operation of the operating member is detected by the electric switch, it is detected that the one rotating member slides in the axial direction with respect to the other rotating member, and the clutch can be switched on and off. It may be detected.

When the electric switch is to detect the operation of the operating member for sliding and moving the one rotating member with respect to the other rotating member as in the latter case, the operating member is used. , The one rotating member is slid and moved only to one side in the axial direction with respect to the other rotating member, and the one rotating member is the other in the axial direction with respect to the other rotating member. The sliding movement to the side is performed by, for example, the elastic force of an elastic member such as a spring, and the elastic force of the elastic member causes the one rotating member to move axially with respect to the other rotating member. By sliding to the side, the working member may also be actuated to the other side, or the actuating member may both axially actuate the one rotating member with respect to the other rotating member. It may be slid to the side.

Further, as described above, the clutch is switched on and off by sliding one of the drive rotating member and the driven rotating member in the axial direction with respect to the other rotating member. The on / off switching principle may be arbitrary.

An example of the clutch is a ball-type clutch in which a ball is interposed between a drive rotating member and a driven rotating member, and the one rotating member slides in the axial direction with respect to the other rotating member. By doing so, the position of the ball in the drive rotating member and the driven rotating member does not connect the connection position connecting the driving rotating member and the driven rotating member in the rotational direction and the driving rotating member and the driven rotating member in the rotational direction. It can be switched to the connection position.

Further, the clutch of another example is formed of a plurality of pins of the drive rotating member and the driven rotating member, which are projected in the axial direction on one of the rotating members, and an axial length on the other rotating member. Each pin of the drive rotating member is composed of a plurality of holes that can be inserted and removed, and the pin is moved by sliding the one rotating member in the axial direction with respect to the other rotating member. It is inserted and removed from the hole to switch the clutch on and off.

Further, as described above, in a clutch in which an operating member for sliding and moving one of the rotating members in the axial direction with respect to the other rotating member is used, the operating member is a shaft of the driven rotating member and the driven rotating member. By moving in the direction, the one rotating member may be slid and moved in the axial direction with respect to the other rotating member, or the operating member may rotate around the axis. It may be a member, and by this rotation, one rotating member may be slid and moved in the axial direction with respect to the other rotating member.

As in the latter case, the operating member is a rotating member that can rotate around an axis, and by this rotation, one rotating member can be slid and moved in the axial direction with respect to the other rotating member. The actuating member is provided with, for example, a contact portion that abuts on a protrusion formed on the outer surface of one of the rotating members, and the contact portion presses the protrusion by rotation of the actuating member about the axis. By doing so, one rotating member may be slid and moved in the axial direction with respect to the other rotating member.

Then, in this way, the actuating member is provided with a contact portion that abuts on the protrusion formed on the outer surface of the one rotating member, and the contact portion is formed by the rotation of the actuating member about the axis. When one rotating member is slid and moved in the axial direction with respect to the other rotating member by pressing, the contact portion may be curved toward the protrusion to form a protruding protruding portion. preferable.

According to this, when the operating member is rotating about the axis in order to slide and move the one rotating member with respect to the other rotating member, the contact portion moves toward the protrusion side. Since it is a curved protruding portion that is curved and protrudes, it is possible to keep the contact portion smoothly in contact with the protrusion in a point contact state, whereby the one rotating member is rotated by the other. It can be smoothly slid and moved in the axial direction with respect to the member.

Further, as described above, the actuating member is provided with a contact portion that abuts on the protrusion formed on the outer surface of the one rotating member, and the contact portion protrudes due to the rotation of the actuating member about the axis. When the one rotating member is slid and moved in the axial direction with respect to the other rotating member by pressing the portion, the protruding portion is formed over the entire outer surface of the one rotating member. It is preferable that the ring-shaped protrusions are formed and the contact portions are provided on both sides in the radial direction of the one rotating member.

According to this, the contact portion presses the protrusion to slide and move the one rotating member in the axial direction with respect to the other rotating member. Since it is performed by the abutting portions provided individually, the pressing force from these abutting portions on both sides in the radial direction of the one rotating member causes the one rotating member to be attached to the other rotating member. It can be slid and moved in the axial direction more smoothly.

Further, in order to provide an operating member for operating the electric switch in the electric / manual switching device of the shutter device according to the present invention, the operating member may be provided with the operating member.

According to this, the operating member for operating the electric switch is provided on the operating member for sliding one rotating member with respect to the other rotating member among the driven rotating member and the driven rotating member. Therefore, the operation of the operating member for switching the on / off of the clutch by sliding the one rotating member in the axial direction with respect to the other rotating member can be more reliably detected by the electric switch. ..

Further, in the case where the operating member for operating the electric switch is provided in the operating member in this way, and when the operating member is a rotating member that rotates about an axis as described above, the operating member is used. An operating member may be provided on the operating member in the peripheral portion of the hole formed for inserting the shaft.

According to this, the rotation of the operating member about the shaft inserted in the hole can be detected more reliably by the electric switch.

Further, as described above, when the operating member for operating the electric switch is provided on the operating member, the operating member and the operating member are manufactured as separate parts, and the operating member and the operating member are welded, screwed, or the like. Alternatively, the operating member may be integrally formed with the operating member as an operating portion that is a part of the operating member.

If the operating member is integrally formed with the operating member as an operating portion that is a part of the operating member as in the latter case, the operating member does not have to be manufactured separately from the operating member, so that the number of parts can be reduced and the structure can be simplified. Can be achieved.

The electric / manual switching device of the shutter device according to the present invention described above can be applied to a shutter device for various purposes, for example, a shutter device for a garage, a shutter device for a window, and an entrance / exit. It can also be applied to shutter devices and the like.

The ring-shaped surface portion 54 provided at the same radial distance as the bottom portion of the recessed portion 53 from the central portion thereof is a circular surface portion continuous over the entire circumference of the drive rotating member 46. Therefore, the front portion of the inner diameter fitting portion 46A of the drive rotating member 46 is a tubular portion 55 protruding forward from the recessed portion 53, and the tubular portion 55 is provided with the recessed portion 53. The radial distance from the central portion of the drive rotating member 46 is shorter than that of the outer peripheral surface 46B, and the outer peripheral surface becomes the ring-shaped surface portion 54.

Further, in the central hole 46C through which the above-mentioned output shaft 45 of the drive rotating member 46 is inserted, a long groove 56 extending from an intermediate portion of the drive rotating member 46 in the axial direction to the rear end of the drive rotating member 46 is formed. A plurality of long grooves 56 are also formed at equal intervals in the circumferential direction of the drive rotating member 46, and in this embodiment, three are formed as shown in FIG. 11B.

12 shows a driven rotating member 48, FIG. 12A is a normal cross-sectional view of the driven rotating member 48, and FIG. 12B is a right side view of the driven rotating member 48. On the inner peripheral surface 48C of the outer diameter fitting portion 48B of the driven rotating member 48, a recessed portion 57 into which a part of the ball 52 can be inserted is formed by being recessed in the outer diameter direction, and the recessed portion 57 is formed. Similar to the recessed portion 53 of the drive rotating member 46, three driven rotating members 48 are formed at equal intervals in the circumferential direction.

Further, as shown in FIG. 9, a long groove 58 having a long dimension in the axial direction is formed on the outer peripheral surface of the output shaft 45 inserted into the drive rotating member 46 and the driven rotating member 48. Three long grooves 58 are also formed at equal intervals in the circumferential direction of the output shaft 45.

When the output shaft 45 is inserted into the inside of the inner diameter fitting portion 46A of the drive rotation member 46 and the inside of the outer diameter fitting portion 48B of the driven rotation member 48, the drive rotation is as shown in FIG. Two balls 61 constituting the ball spline 60 together with the long grooves 56 and 58 of the member 46 are separated and inserted into the long groove 56 of the member 46 and the long groove 58 of the output shaft 45 by the separate member 62. As a result, the output shaft 45 and the drive rotation member 46 are connected in the rotational direction by the ball spline 60, the rotation of the output shaft 45 is transmitted to the drive rotation member 46, and the drive rotation is caused by the ball spline 60. The member 46 is slidable in the axial direction with respect to the output shaft 45. Then, the closing member 63 is fastened to the rear end of the drive rotating member 46 with a fastener such as a screw, and the opening end of the long groove 56 is closed by the closing member 63.

Further, when the inner diameter fitting portion 46A of the drive rotating member 46 is fitted inside the outer diameter fitting portion 48B of the driven rotating member 48, the recessed portion 53 of the drive rotating member 46 and the recessed portion of the driven rotating member 48 are formed. The ball 52 is inserted into the 57, and the closing member 64 is fastened to the rear end of the driven rotating member 48 with a fastener 65 such as a screw, and the opening end of the recessed portion 57 is closed by the closing member 64. ..

In the above, as shown in FIG. 9, when the drive rotating member 46 is forward urged toward the driven rotating member 48 side by the elastic member 47 by the coil spring wound around the outer periphery of the output shaft 45. The ball 52 is located at the position of the recessed portion 53 of the drive rotating member 46 and the recessed portion 57 of the driven rotating member 48. Since the width dimension of the drive rotating member 46 and the driven rotating member 48 in these recesses 53 and 57 in the rotation direction is short so that only a part of the ball 52 can be inserted, the recesses 53 and 57 Is a restraining portion that restrains the ball 52 in the rotational direction of the drive rotating member 46 and the driven rotating member 48. Therefore, the clutch 49 at this time is a drive rotating member from the output shaft 45 via the ball spline 60. The rotation transmitted to the 46 is also transmitted to the driven rotating member 48 in the ON state.

Therefore, at this time, the arrangement position of the ball 52 in the drive rotating member 46 and the driven rotating member 48 is such that the clutch 49 is turned on by connecting the driving rotating member 46 and the driven rotating member 48 in the rotational direction via the ball 52. It is the connection position to be connected.

On the other hand, as shown in FIG. 10, the drive rotating member 46 retreats to the electric motor side of the switch 26, which is on the opposite side to the driven rotating member 48 side against the elastic force of the elastic member 47. At that time, the ball 52 maintains a state in which a part of the ball 52 is inserted into the recessed portion 57 of the driven rotating member 48, escapes from the recessed portion 53 of the drive rotating member 46, and forms a ring-shaped surface portion 54 of the drive rotating member 46. In order to reach the ball 52, the position of the ball 52 at this time is the position of the ring-shaped surface portion 54 provided on the driven rotating member 48. Since the ring-shaped surface portion 54 is formed over the entire circumference of the driven rotating member 48, it is an unconstrained portion that does not constrain the ball 52 in the rotational direction of the driven rotating member 46 and the driven rotating member 48. Therefore, the clutch 49 at this time is in an off state in which the rotation transmitted from the output shaft 45 to the drive rotation member 46 is not transmitted to the driven rotation member 48.

Therefore, at this time, the arrangement position of the ball 52 in the drive rotating member 46 and the driven rotating member 48 is such that the clutch 49 is disengaged by not connecting the drive rotating member 46 and the driven rotating member 48 in the rotational direction via the ball 52. It is a non-connection position.

As described above, in the present embodiment, when the arrangement position of the ball 52 is changed to the connected position and the non-connected position because the clutch 49 is switched on and off, the ball 52 is used as the drive rotating member 46 and the driven rotating member 48. On the other hand, since the clutch 49 rolls on and off, the switching of the clutch 49 on and off is performed in a state where there is no friction or almost no friction due to the rolling of the ball 52, whereby the clutch 49 is turned on and off. Achieve smooth switching

In FIG. 7, the operating member 70 is operated to retract the drive rotating member 46 to the electric motor side of the switch 26, which is on the opposite side to the driven rotating member 48 side, against the elastic force of the elastic member 47 described above. It is shown. The drive rotating member 46, the driven rotating member 48, and the operating member 70, which is an element constituting the clutch 49 together with the ball 52, rotate about the shaft 71 around the above-mentioned extension portion 31A of the base member 31. The shaft 71 is freely arranged, and in the present embodiment, the shaft 71 is a fastener such as a screw for rotatably fastening the operating member 70 to the extending portion 31A.

13 shows a working member 70, FIG. 13A is a plan view of the working member 70, FIG. 13B is a right side view of the working member 70, and FIG. 13C is a right side view of the working member 70. , Is a perspective view of the actuating member 70. The actuating member 70 is composed of an elongated plate-shaped base member 72 and an auxiliary member 73 coupled to the upper surface of the base member 72, and the auxiliary member 73 is formed by bending the plate material into a U shape. Therefore, the auxiliary member 73 is composed of two upper and lower arm portions 73A and 73B and a connecting portion 73C connecting the base end portions of these arm portions 73A and 73B, and among the arm portions 73A and 73B, the auxiliary member 73 is composed of connecting portions 73C. The lower arm portion 73B is joined to a portion in the middle of the base member 72 in the length direction by welding or the like. A hole 74 for inserting a shaft 71, which is a rotation center axis of the operating member 70, is provided at the tip of the base member 72.

As shown in FIG. 7, on the outer surface of the drive rotating member 46, a protrusion 46D protruding in the outer diameter direction of the drive rotating member 46 is provided at the rear end portion of the drive rotating member 46. The protrusion 46D is a ring-shaped protrusion continuously formed over the entire circumference of the drive rotating member 46. In the actuating member 70, the positions of the two upper and lower arm portions 73A and 73B of the auxiliary member 73 are located on both sides in the radial direction of the drive rotating member 46, and the extension portion 31A of the base member 31 is centered on the shaft 71. Arranged rotatably. In other words, in the actuating member 70, the two upper and lower arm portions 73A and 73B of the auxiliary member 73 sandwich the drive rotating member 46 in the diameter direction of the drive rotating member 46, and the actuating member 70 is attached to the extending portion 31A of the base member 31. It is rotatably arranged around the shaft 71. Each of the arm portions 73A and 73B is provided with a contact portion 75 that abuts on the ring-shaped protrusion 46D at the tip portion facing the ring-shaped protrusion 46D, and these contact portions 75 are provided with a ring. It is a curved protrusion that protrudes toward the projecting portion 46D.

Further, as shown in FIG. 13, the end portion of the base member 72 of the operating member 70 opposite to the end portion provided with the hole 74 is a string-shaped member shown in FIG. 7. A connecting portion 78 is provided for connecting one end of the wire 76 with the connecting member 77. As shown in FIG. 7, the wire 76 is inserted into the outer cable 80 whose end is coupled to the base member 31 by the coupling member 79, and as shown in FIG. 2, a switch. A switching actuator (not shown) that extends along the aforementioned unit structure 28 composed of 26 and the control device 27, and the other end of the wire 76 is operated to switch the clutch 49 on and off. The switching operation device is arranged on one of a pair of left and right guide rails 2 for guiding the opening / closing movement of the shutter curtain 1, for example.

When the operating lever provided on the switching actuator is operated, as shown in FIG. 8, the operating member 70 rotates about the shaft 71 due to the pulling force acting on the wire 76.

In FIG. 7, where no tensile force acts on the wire 76, the drive rotating member 46 moves on the output shaft 45 toward the driven rotating member 48 due to the elastic urging force of the elastic member 47, so that the clutch 49 is shown in FIG. As shown in, it is on. When the clutch 49 is turned on in this way, when the "open" operation button or the "closed" operation button of the operation device provided with the above-mentioned "open", "close", and "stop" operation buttons is operated. The output shaft 45 is rotated by the driving force of the electric motor of the switch 26 controlled by the control device 27 to which the signal from the operating device is input, and this rotation is caused by the ring gear 35 via the drive rotating member 46 and the driven rotating member 48. The rotating body 14 of the take-up shaft 6 electrically performs forward rotation for opening and moving the shutter curtain 1 or reverse rotation for closing and moving the shutter curtain 1.

Further, when the operation lever of the switching operation device described above is operated, the operating member 70 rotates about the shaft 71 as shown in FIG. 8 due to the pulling force acting on the wire 76, so that the operating member The contact portion 75 provided on the 70 presses the protrusion 46D provided on the outer surface of the drive rotating member 46, and by this pressing, the drive rotating member 46 is opposite to the elastic urging direction by the elastic member 47. While compressing the elastic member 47 in the direction, it slides and moves with respect to the driven rotating member 48. This causes the clutch 49 to switch from on to off, as shown in FIG. When the clutch 49 is disengaged, the connection between the drive rotating member 46 and the driven rotating member 48 is cut off. Therefore, the shutter curtain 1 is manually opened and closed by the hand hooked on the handle member 10 shown in FIG. The rotating body 14 of the clutch 6 can be rotated.

Further, when the operation lever of the switching operation device is operated in the opposite direction to the above operation, the pulling force acting on the wire 76 disappears, whereby the drive rotating member 46 is as shown in FIG. 7. In addition, the elastic urging force of the elastic member 47 slides and moves toward the driven rotating member 48, and the clutch 49 switches from off to on. Therefore, the rotation of the rotating body 14 of the winding shaft 6 for opening and closing the shutter curtain 1 Will be able to be done electrically. Further, when the drive rotating member 46 slides and moves toward the driven rotating member 48 due to the elastic urging force of the elastic member 47, the operating member 70 acts on the drive rotating member 46 with the pressing force from the protrusion 46D on the contact portion 75. By doing so, the shaft 71 returns to the center and rotates.

When the clutch 49 is switched from off to on, the positions of the recessed portion 53 of the drive rotating member 46 and the recessed portion 57 of the driven rotating member 48 rotate because the shutter curtain 1 has been manually opened and closed by then. When the shutter curtain 1 is displaced in the direction, the drive rotating member 46 is rotated via the output shaft 45 by the driving force of the electric motor in order to electrically open and close the shutter curtain 1. Since the positions naturally coincide with each other in the rotation direction, the balls 52 are inserted into the recesses 53 and 57 at this time, whereby the clutch 49 is switched from off to on.

As described above, the operating member 70 according to the present embodiment is a rotating member that rotates about the shaft 71 by a tensile force acting on the wire 76, and the operating member 70 is a drive rotating member. An abutting portion 75 that abuts on the protrusion 46D provided on the outer surface of the 46 is provided, and the abutting portion 70 is rotated around the shaft 71 to disengage the clutch 49. The portion 75 presses the protrusion 46D so that the drive rotating member 46 slides to the side opposite to the driven rotating member 48 side, and the contact portion 75 is curved toward the protrusion 46D. It is a curved protrusion that protrudes. Therefore, when the operating member 70 rotates about the shaft 71, the contact portion 75 continues to smoothly contact the protrusion 46D in a point contact state, whereby the drive rotation member The 46 can be smoothly slid and moved in the axial direction of the output shaft 45 with respect to the driven rotating member 48.

Further, the protrusion 46D provided on the outer surface of the drive rotation member 46 is a ring-shaped protrusion formed over the entire circumference of the drive rotation member 46, and the protrusion 46D is formed on the operating member 70. Since two contact portions 75 are provided on both sides in the radial direction of the drive rotating member 46 as curved protrusions that are curved to the side and protrude, the contact portions 75 are the protrusions 46D. The drive rotation member 46 can be slid and moved in the axial direction with respect to the driven rotation member 48 by pressing the drive rotation member 46 by pressing pressure from both sides in the radial direction of the drive rotation member 46, whereby the drive rotation member 46 can be driven and rotated. The sliding movement of the member 46 with respect to the driven rotating member 48 in the axial direction can be performed more smoothly.

Further, in the shutter device according to the present embodiment, as shown in FIGS. 7 and 8, an electric switch 81 is arranged in the extension portion 31A of the base member 31 of the switch 26 described above. The electric switch 81 is for detecting the on / off switching of the clutch 49. More specifically, in the electric switch 81, the drive rotating member 46 slides in the axial direction with respect to the driven rotating member 48. It is for detecting the on / off switching of the clutch 49 by detecting that the clutch 49 is to be turned on. The electric switch 81 comes into contact with the operating member 82 arranged on the extending portion 31A of the base member 31, and is operated by the operating member 82. The operating member 70 according to the present embodiment is operated by the operating member 82. As will be described later, since the electric switch 81 is provided with an operating member 82 for operating the electric switch 81, the electric switch 81 slides the drive rotating member 46 with respect to the driven rotating member 48 in the axial direction. It is operated by the operation of the operating member 70 of the above.

More specifically, as shown in FIG. 13, the operating member 70 is a moving member in the peripheral portion of the hole 74 for inserting the shaft 71 formed in the base member 72 described above. An operating member 82 is provided, and the operating member 82 is integrally formed with the operating member 70 as an operating portion that is a part of the operating member 70. Therefore, when the actuating member 70 rotates about the shaft 71 in order to slide the drive rotating member 46 with respect to the driven rotating member 48 in the axial direction, the electric switch 81 becomes a part of the actuating member 70. It is operated by the operating member 82 integrally formed with the operating member 70 as the operating unit.

The operating member 82 may be manufactured as a separate part from the operating member 70 and coupled and integrated with the operating member 70. However, as described above, the operating member 82 may be a part of the operating member 70 as an operating unit. By providing it integrally with the operating member 70, it is possible to reduce the number of parts and simplify the structure.

In this embodiment, as shown in FIG. 8, the operating member 70 is rotated about the shaft 71 by the pulling force of the wire 76, and as shown in FIG. 7, the pulling force of the wire 76 is pulled. Due to the extinction of the force, the operating member 70 returns to the center of the shaft 71 and rotates via the drive rotating member 46 due to the elastic force of the elastic member 47, and when the clutch 49 is switched on and off, the operating member is switched. The operating member 82 also rotates about the shaft 71 integrally with the 70, whereby the electric switch 81 operates, and the on / off switching of the clutch 49 is detected by the electric switch 81.

The electric signal from the electric switch 81 that detects the on / off switching of the clutch 49 is sent to the control device 27 for electrically controlling the switch 26. As a result, when the disengagement of the clutch 49 is detected by the electric switch 81, the "open" signal sent from the operation device provided with the above-mentioned "open", "close", and "stop" operation buttons to the control device 27. The "closed" signal and the "stop" signal are invalidated in the control device 27, and the control device 27 does not control the switch 26.

Further, instead of invalidating the "open", "closed", and "stop" signals in the control device 27, the control device 27 to which the "open" signal and the "closed" signal are sent causes the electric motor of the switch 26 to operate for a predetermined time. For example, while idling for only one second, the control device 27 operates the notification means such as an alarm device and a display device to operate the operation device that the clutch 49 is turned off by voice and / or display. You may be able to warn those who are doing it. In such a case, when the "stop" signal is sent to the control device 27, the control device 27 activates a notification means such as an alarm device or a display device to clutch by voice and / or display. It may be possible to warn the person operating the above-mentioned operating device that 49 is turned off.

Further, when the clutch 49 that has been turned off is turned on, the electric signal of the electric switch 81 that detects this is sent to the control device 27, whereby the control device is "open", "closed", and "stopped". The shutter curtain 1 is operated by operating the "open" button of the operation device on the display device arranged in the operation device provided with the operation button of the above, or the display device provided in the shutter device separately from the operation device. Is displayed to encourage the user to open and move to the fully open position. As a result, regardless of the position where the shutter curtain manually opened / closed and moved when the clutch 49 is disengaged, the operator of the operating device opens the shutter curtain 1 in the fully open position according to the display of the display device. A detection means for detecting the position of the shutter curtain 1 at any time by opening and moving the shutter curtain 1 by the rotation speed of the electric motor of the switch 26 and the rotation speed of the rotating body 14 of the take-up shaft 6. The count is reset so that the origin of the count can be set at the fully open position of the shutter curtain 1. In this case, when the "close" button of the operation device is operated, the control device 27 invalidates the "close" signal and does not drive the electric motor of the switch 26.

Further, the display device or the operation device arranged in the operation device provided with the operation buttons of "open", "close", and "stop" by the electric signal from the electric switch 81 that detects the on / off of the clutch 49. In the display device provided in the shutter device separately, which state the clutch 49 is currently in, on or off, that is, whether the shutter curtain 1 is currently opened or closed, electric or manual. It may be displayed whether it is in a state where it can be moved.
