[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 3, an electric shutter 1 according to this embodiment is attached to the framework of a building and is arranged so as to be able to open and close an opening of the building. The electric shutter 1 includes a frame body 2 and a shutter main body 4 attached to the frame body 2 so as to be able to wind up and unwind a shutter curtain 41. In the following description, the left-right direction of the electric shutter 1 is defined as the X-axis direction, the up-down direction of the electric shutter 1 is defined as the Y-axis direction, and the front-rear direction (projection direction) of the electric shutter 1 is defined as the Z-axis direction. The X, Y, and Z axis directions are perpendicular to each other.

[0010] The frame body 2 comprises left and right vertical frames 21, a top plate 22 screwed to the upper ends of the left and right vertical frames 21, an inspection plate 23 hung on the outer edge of the top plate 22, an upper frame 25 (lintel) attached to the upper part of the left and right vertical frames 21 and below the top plate 22, and a lower frame 26 attached to the lower ends of the left and right vertical frames 21. Guide rails 211 that guide the left and right ends of the slats 3 up and down are attached along the Y-axis direction to the left and right vertical frames 21. An engagement groove (not shown) is formed in the outer edge of the top plate 22 along the X-axis direction, and the inspection plate 23 is attached by having its upper edge hooked into the engagement groove along the X-axis direction of the top plate 22 and the left and right ends of its lower edge screwed to mounting pieces 473 of the case side plates 47 described later, and the inspection plate 23 can be removed from the frame body 2 by unscrewing the mounting pieces 473 of the inspection plate 23. In this frame body 2, the upper parts of the left and right vertical frames 21, the top plate 22, and the upper frame 25 form the storage section 20 in which the shutter main body 4 is disposed, and the storage section 20 can be opened and closed from the front side (outside the room) by attaching and detaching the inspection plate 23. In addition, a back plate is attached to the upper parts of the left and right vertical frames 21 that define the storage section 20, and the mounting pieces 472 of the case side plates 47 are detachably screwed to this back plate.

[0011] The shutter main body 4 includes a shutter case 45, the shutter curtain 41 described above which is composed of a plurality of connected slats 3, a shutter winding shaft 42 which is supported by the shutter case 45 and extends along the X-axis direction so as to be capable of winding and unwinding the shutter curtain by rotational drive, a tubular motor 48 as an electric motor which is connected to the shutter winding shaft 42 so as to be capable of rotating the shutter winding shaft 42, a control unit 31 which is composed of an arithmetic device and a memory device which control the rotation of the tubular motor 48, a communication unit 49 (communication unit) which receives a signal from a remote control device 494 such as a remote controller and transmits a command signal to the control unit 31, and an emergency operation device 70 which releases the connection between the shutter winding shaft 42 and the tubular motor 48. The shutter winding shaft 42 incorporates a tubular motor 48 and a control unit 31, and is equipped with a return spring (not shown) so that when the emergency operating device 70 releases the connection with the tubular motor, the return spring is biased to wind up the shutter curtain 41. A communication section 49 (communication unit) is connected to the control section 31 by a wire 61. The control section 31 receives a command signal transmitted from the communication section 49 based on an operation signal from a remote control device 494 such as a remote controller or an operation signal generated by operating an operation button on the operation section 492, controls the rotation of the tubular motor, and rotates the shutter winding shaft 42 to wind up or unwind the shutter curtain 41. The control section 31 also executes a first execution mode or a second execution mode (described later) based on a command signal transmitted from the communication section 49 by operating a program button (PB button) on the operation section 492. The shutter curtain 41 is configured by connecting the above-mentioned multiple slats 3 to each other so that they can rotate freely, and the uppermost slat 3 among the multiple slats 3 is attached to the shutter winding shaft 42, and the lowermost slat 3 is attached to a seat plate that sits on the lower frame 26. Therefore, the shutter curtain 41 moves up and down in the Y-axis direction while being guided by the guide rail 211 by the rotation of the shutter winding shaft 42. The shutter case 45 comprises a case back plate 46 aligned along the X-axis direction, and a pair of case side plates 47 whose rear portions are attached to the left and right edges of the case back plate 46 and protrude forward, and a resin side cap 7 covering the side of the shutter body 4 is removably attached to the case side plates 47 at a position forward of the upper part of the vertical frame 21 in the Z-axis direction. At both ends in the X-axis direction of the case back plate 46, rear wiring ports 461 through which wiring 61 connected to the communication unit 49, a power source, etc. are inserted are formed. In this embodiment, the wiring 61 and the connectors connecting these are referred to as wiring 6.

[0012] 2 and 3, the case side plate 47 has a side plate main body 471 that rotatably supports one end of the shutter winding shaft 42, a pair of upper and lower mounting pieces 472 that are detachably screwed from the front to the back plate of the vertical frame 21, mounting pieces 473 to which the left and right ends of the lower edge of the inspection plate 23 are detachably screwed, and a pair of upper and lower cap mounting pieces 474 to which the side caps 7 are screwed. The cap mounting pieces 474 are located forward of the mounting pieces 472. The side plate body 471 is flat, and its front portion is disposed so as to protrude forward in the Z-axis direction beyond the vertical frame 21. A bearing member 475 that rotatably supports the shutter winding shaft 42 is attached at approximately the center of the side plate body 471, and a wiring port 471A (central wiring port) formed as a rectangular hole through which the wiring 6 from the shutter winding shaft 42 passes is formed. The central wiring port 471A is formed obliquely with respect to the Y-axis direction. A side wiring port 471B through which the wiring 61 passes is formed at a position on the side plate body 471 rearward and above the position of the shutter winding shaft 42. Here, the aforementioned communication unit 49 is attached to the outer surface side of the side plate main body 471 (see FIG. 3), and the wiring 61 from the shutter winding shaft 42 side is connected to the communication unit 49 through the central wiring port 471A, and the wiring 61 connected from the communication unit 49 to other devices etc. extends to the space on the indoor side of the electric shutter 1 through the side wiring port 471B and the rear wiring port 461. A guide unit 478 is formed at the front lower part of the side plate main body 471 to guide the edge of the slat 3 in the X-axis direction and suppress lateral displacement in the X-axis direction. 3, communication unit 49 is disposed at a position forward of vertical frame 21 and at the upper front position of side panel main body 471 whose side surface is covered by side cap 7, and the main body portion is housed in housing 491. At the bottom of housing 491, operation unit 492 composed of a USB socket, operation buttons, program buttons, etc. is disposed. The wiring 6 and the communication unit 49 arranged on the outer surface side of the side plate body 471 are arranged in the installation space 10 (space) formed between the outer surface side of the case side plate 47 and the back plate fixed to the vertical frame 21. Since the communication unit 49 is arranged on the outer surface side of the case side plate 47, not on the inner surface side, interference between the communication unit 49 and the slat 3 can be eliminated, and the need to provide the communication unit 49 with a guide function for guiding the slat can be eliminated, so that the configuration of the communication unit 49 can be simplified. Furthermore, since the wiring 6 from the communication unit 49 is also arranged along the outer surface of the side plate body 471, it is possible to eliminate interference between the wiring 6 along the side plate body 471 and the slat 3. For example, when the communication unit 49 and the wiring 6 are arranged along the inner surface of the side plate body 471, it is necessary to cover the wiring 6 with a slat guide (guide member) that suppresses interference between the wiring 61 and the slat 3. However, this need can be eliminated in this embodiment, and the number of parts of the slat guide can be reduced and the configuration can be simplified. Furthermore, after the electric shutter 1 is assembled, the communication unit 49 is surrounded by the case side panels 47, the vertical frame 21, the side caps 7, the top panel 22 and the inspection panel 23, thereby improving waterproofing. In addition, between the case side panel 47 and the side cap 7, there is a space in the X-axis direction that is open at the front side as shown in Figure 2, and the aforementioned communication unit 49 is arranged in this space. Therefore, even if the side cap 7 is left attached, by removing the inspection plate 23 described below, the operating unit 492 provided on the communication unit 49 can be operated from outside the room.

[0013] The case side plate 47 rotatably supports (axially supports) the shutter winding shaft 42 on the inner side via a bearing member 475. The bearing member 475 has a shaft connecting portion 476 to which the shutter winding shaft 42 is rotatably connected, and a fixed portion 477 fixed to the case side plate. The shaft connecting portion 476 is formed in a substantially U-shape, is inserted into the central wiring port 471A from the outer surface side of the side plate main body 471, and is disposed so as to protrude in the X-axis direction toward the shutter winding shaft 42 side from the inner surface of the case side plate 47. The fixed portion 477 is bent in three directions from the shaft connecting portion 476 toward the outside (the outer periphery side in a virtual plane perpendicular to the X-axis direction), is disposed so as to extend along the outer surface of the side plate main body 471, and is fixed to the side plate main body 471 by riveting from the outer surface side. The fixing portion 477 may be riveted to the inner surface of the side plate main body 471, in which case the shaft connecting portion 476 is not inserted into the central wiring port 471A.

[0014] In this embodiment, the guide portion 478 is formed by machining the side plate main body 471 into a rectangular convex shape, but the guide portion 478 may be formed by attaching a separate member to the side plate main body 471.

[0015] The mounting pieces 472, 473 and the cap mounting piece 474 extend outward in the X-axis direction toward the vertical frame 21. The mounting piece 472 extends outward in the X-axis direction from the upper and lower edges of the side plate body 471 and is configured along the Y-axis direction so as to be oriented to be screwed from the front side in the Z-axis direction. The mounting piece 473 extends outward in the X-axis direction from the lower edge of the side plate body 471 and is configured along the Z-axis direction so as to be screwed from the lower side in the Y-axis direction. The lower cap mounting piece 474 extends from the lower front edge of the side plate body 471 and is configured along the Y-axis direction so as to be screwed from the front side in the Z-axis direction, and the upper cap mounting piece 474 extends from the upper front edge of the side plate body 471 so as to be screwed from the front side in the Z-axis direction. In addition, the upper front edge of the side panel main body 471 is inclined toward the rear (inside the room) in the Y-axis direction more than the lower front edge, and therefore the upper cap mounting piece 474 is inclined in the same manner as the upper front edge of the side panel main body 471.

[0016] 2 and 4, the emergency operation device 70 includes a clutch mechanism 71 that connects and disconnects the shutter winding shaft 42 and the tubular motor 48, a pull tab 72 that serves as an emergency operation unit that is connected by wire to the clutch mechanism 71 and is located outside the electric shutter 1 on the indoor side, and a switch 73 that operates in conjunction with the clutch mechanism 71. The clutch mechanism 71 is attached to the tubular motor 48. The switch 73 is configured and arranged so that it is turned on in conjunction with the clutch mechanism 71 when the shutter winding shaft 42 and the tubular motor 48 are disconnected, and is turned off in conjunction with the clutch mechanism 71 when the shutter winding shaft 42 and the tubular motor 48 are connected. In this emergency operating device 70, when the pull tab 72 is pulled, the clutch mechanism 71 operates to disconnect the shutter winding shaft 42 and the tubular motor 48, and the switch 73 is turned on in conjunction with the disconnecting operation by the clutch mechanism 71. When the pull tab 72 is further pulled in this state, the clutch mechanism 71 operates to connect (reconnect) the shutter winding shaft 42 and the tubular motor 48, and the switch 73 is turned off in conjunction with the connecting operation by the clutch mechanism 71. Here, when the shutter winding shaft 42 is disconnected from the tubular motor 48, the braking force of the tubular motor 48 is no longer applied to the shutter winding shaft 42, and the shutter curtain 41 is wound up by the bias of the return spring described above. As a result, the electric shutter 1 is opened in an emergency by operating the emergency operating device 70. The emergency operating device 70 in this embodiment allows the electric shutter 1 to be manually opened in an emergency such as a power outage.

[0017] [Description of processing of the control unit 31 based on operation of the emergency operation device 70] The control unit 31 performs the following processing as shown in FIG. 5 based on the operation of the emergency operation device 70, specifically, on / off of the switch 73. When the switch 73 is turned on for the first time by operating the pull tab 72, the upper / lower limit position re-learning mode M0, which sets the upper and lower limit positions of the shutter curtain 41, is set, and the upper / lower limit position re-learning mode M0 is executed. Simultaneously with the first turning on of the switch 73, a countdown of a predetermined time limit (one minute in this embodiment) begins (process S0).

[0018] In the upper and lower limit position re-learning mode M0, first, the current upper limit position and lower limit position settings for the shutter curtain 41 are released (reset), and the shutter winding shaft 42 and the tubular motor 48 are connected by the second operation of the pull tab 72 and the switch 73 is turned off. Then, the tubular motor 48 is operated to fully unwind the shutter curtain 41 to a position where it abuts against the lower frame 26, and the fact that the shutter curtain 41 has reached this position is detected and the tubular motor 48 is newly set to the lower limit position. Next, the tubular motor 48 is operated to wind the shutter curtain 41 to a position where it can be fully wound, and the fact that the shutter curtain 41 has reached this position is detected and the tubular motor 48 is newly set to the upper limit position. In this embodiment, the detection of each position is performed based on the change in the current value supplied to the tubular motor 48. The lower limit position and the upper limit position may be set to positions slightly adjusted from the detected positions. Furthermore, if the switch 73 is turned on n times (including the first time) consecutively within a predetermined time interval (within a few seconds) during counting the time limit, the count ends and a first execution mode M1 is executed as described below (process S1). If the switch 73 is turned on N times (including the first time) consecutively within a predetermined time interval (within a few seconds) during counting the time limit, the count ends and a second execution mode M2 ​​is executed as described below (process S2). If the switch 73 is turned on n times or a number other than N times (including the first time) consecutively within a predetermined time interval (within a few seconds) during counting the time limit, the count ends and the upper / lower limit position re-learning mode M0 is continued without mode transition (process S3).

[0019] When the switch 73 is turned on n times in succession within a predetermined time interval (within a few seconds) within the aforementioned time limit, the counting of the time limit is terminated, the upper and lower limit position re-learning mode M0 is temporarily stopped, and the first execution mode M1 is selected and executed (step S2). In this embodiment, n times is set to 3 times for convenience. In this embodiment, the first execution mode M1 is the same mode as the mode when the program button (PB button) of the operation unit 492 is pressed briefly. The first execution mode M1 is a mode for executing one of various processes such as changing the settings of the control unit, initialization, and re-registration of the remote controller 494, and while the first execution mode M1 is being executed, the settings in the first execution mode M1 are processed by turning the switch 73 on and off by operating the pull tab 72. Note that the setting process may be performed by operating the remote controller 494 instead of the setting process by operating the pull tab 72 while the first execution mode M1 is being executed.

[0020] If the switch 73 is turned on N times, which is different from the n times, within a predetermined time interval (within a few seconds) within the aforementioned time limit, the count of the time limit is terminated, the upper and lower limit position re-learning mode M0 is temporarily stopped as described above, and a second execution mode M2, which is different from the first execution mode M1, is selected and executed. In this embodiment, N times is set to 5 times for convenience. In this embodiment, the second execution mode M2 ​​is the same mode as the mode when the program button (PB button) of the operation unit 492 is pressed and held. The second execution mode M2 ​​is a mode for executing another one of the processes such as changing the settings of the control unit, initialization, and re-registration of the remote controller 494, and during execution of the second execution mode M2, the settings in the second execution mode M2 ​​are processed by turning on and off the switch 73 by operating the pull tab 72. Note that the setting process may be performed by operating the remote controller 494 instead of the setting process by operating the pull tab 72 during execution of the second execution mode M2.

[0021] After the first execution mode M1 or the second execution mode M2 ​​is terminated, the upper and lower limit position re-learning mode M0 that had been stopped is resumed immediately after the termination, and the above processing is automatically performed to newly set the upper limit position and the lower limit position of the shutter curtain 41. When the above is completed, the process by the control unit 31 ends (process S4).

[0022] In this way, the control unit 31 selects and sets an execution mode according to the number of times the switch 73 is operated within the aforementioned time limit, and performs processing based on each execution mode. Note that if the switch 73 is operated only once, the switch 73 is not turned on n times or N times, so the first execution mode M1 and the second execution mode M2 ​​are not executed, and the upper and lower limit position re-learning mode M0 is executed automatically without being stopped.

[0023] [Variations] In the above embodiment, the first execution mode M1 and the second execution mode M2 ​​can be selected based on the operation of the emergency operating device 70, but this is not limited thereto, and three or more modes may be selectable, or one mode may be selected and executed. In the above embodiment, a common first execution mode M1 or second execution mode M2 ​​is executed based on the operation of the emergency operating device 70 and the operation of the program button of the operating unit 492, but this is not limited to the above, and the mode executed by the operation of the emergency operating device 70 and the mode executed by the operation of the program button of the operating unit 492 do not have to correspond to each other. In the above embodiment, the upper and lower limit position re-learning mode M0 is automatically resumed after the first execution mode M1 or the second execution mode M2 ​​ends. However, the present invention is not limited to this and may be resumed based on a manual operation. In the embodiment, the switch 73 is turned on in conjunction with the clutch mechanism 71 when the shutter winding shaft 42 and the tubular motor 48 are disconnected, and turned off in conjunction with the clutch mechanism 71 when the clutch mechanism 71 connects the shutter winding shaft 42 and the tubular motor 48, but is not limited to this. The switch 73 may be turned off in conjunction with the clutch mechanism 71 when the shutter winding shaft 42 and the tubular motor 48 are disconnected, and may be turned on in conjunction with the clutch mechanism 71 when the shutter winding shaft 42 and the tubular motor 48 are connected by the clutch mechanism 71. In this case, the first execution mode M1 or the second execution mode M2 ​​may be executed depending on the number of times the switch 73 is turned off within a predetermined time limit. In the above embodiment, an execution mode such as the first execution mode M1 or the second execution mode M2 ​​is selected depending on the number of times the switch 73 is operated, but the present invention is not limited to this and an execution mode may be selected depending on the operation time of the switch 73. That is, when the switch 73 is turned on when the connection is released as in the present embodiment, an execution mode may be selected when the on state is continuously maintained for a predetermined time (e.g., 5 seconds). In addition, the form in which an execution mode is selected depending on the operation time of the switch 73 also includes a case in which, when the switch 73 is turned off when the connection is released, the off state is continuously maintained for a predetermined time as described above. In the above embodiment, in the upper and lower limit position re-learning mode M0, the lower limit position of the shutter curtain 41 is newly set, and then the upper limit position of the shutter curtain 41 is newly set, but this is not limited to the above, and the upper limit position may be newly set, and then the lower limit position of the shutter curtain 41 may be newly set.

[0024] [Summary of the invention] (1) The electric shutter of the present invention is an electric shutter comprising a frame body and a shutter body attached to the frame body so as to be able to roll up and extend a shutter curtain, the shutter body comprising a shutter case, a shutter winding shaft supported by the shutter case and aligned in the left-right direction so as to be able to roll up and extend the shutter curtain by rotational drive, an electric motor connected to the shutter winding shaft so as to be able to rotate about the shutter winding shaft, a control unit for controlling the rotation of the electric motor, and an emergency operation device for disconnecting the shutter winding shaft and the electric motor, the emergency operation device comprising an emergency operation unit disposed outside the electric shutter, a clutch mechanism for disconnecting and connecting the shutter winding shaft and the electric motor by operation of the emergency operation unit, and a switch that is switched on and off in conjunction with the clutch mechanism when disconnecting the shutter winding shaft and the electric motor and when connecting the shutter winding shaft and the electric motor by the clutch mechanism, the control unit being characterized in that an execution mode that is selected according to the number of times or the operation time of the switch is set. According to the electric shutter of the present invention, the control unit sets an execution mode that is selected according to the number of times or duration of operation of the switch in the emergency operation device described above. Therefore, compared to, for example, in an electric shutter in which buttons such as an operation button and a program button are provided in a communication unit, where each component such as the shutter curtain must be removed and then each button on the communication unit must be operated, the execution mode can be selected and set simply by operating the emergency operation unit located outside the electric shutter, which eliminates the need to remove each component such as the shutter curtain and makes it possible to easily set the execution mode of the control unit by utilizing the operation of the emergency operation unit. (2) In the electric shutter of the present invention, the control unit may set the execution mode to be selected in accordance with the number of times the switch is operated within a time limit. With this configuration, the risk of the number of times the switch is operated being erroneously recognized can be reduced. (3) In the electric shutter of the present invention, the switch may be turned on in conjunction with the clutch mechanism when the shutter winding shaft and the electric motor are disconnected, and may be turned off in conjunction with the clutch mechanism when the shutter winding shaft and the electric motor are connected by the clutch mechanism. According to such a configuration, for example, when the above-mentioned connection release is performed, an execution mode can be selected according to the number of operations or the operation time that is turned on in conjunction with the clutch mechanism. (4) In the electric shutter of the present invention, when the switch is turned on for the first time, a time limit count is started and an upper / lower limit position re-learning mode is set to set the upper and lower limit positions of the shutter curtain, a first execution mode is selected when the switch is turned on n times within the time limit, and a second execution mode is selected when the switch is turned on N times within the time limit. With this configuration, the upper and lower limit positions of the shutter curtain can be re-learned when an electric shutter is operated in an emergency by the emergency operating device, and the first execution mode and the second execution mode can be selected and set depending on the number of times the switch is operated within the time limit. (5) In the electric shutter of the present invention, the control unit may stop execution of the upper and lower limit position re-learning mode when the first execution mode or the second execution mode is selected, and may resume execution of the upper and lower limit position re-learning mode after the first execution mode or the second execution mode has ended. With this configuration, even if the connection with the electric motor is temporarily released by operating the emergency operating unit and the first execution mode or the second execution mode is selected, the upper limit and lower limit positions of the shutter curtain can be automatically re-learned immediately after the end of the first execution mode or the second execution mode, thereby preventing the settings of the upper limit and lower limit positions of the shutter curtain from becoming misaligned. (6) In the electric shutter of the present invention, the emergency operation unit may be arranged on the indoor side of the electric shutter, and an operation unit for setting the execution mode may be provided on the outdoor side of the electric shutter. With this configuration, when the execution mode of the control unit in the electric shutter is set from outside the room, it can be set by operating the above-mentioned operation unit, and when the execution mode is set from inside the room, it can be set by operating the above-mentioned emergency operation unit.
