Description

[Technical Field]

[0001] The present invention relates to a multi-remote controller capable of operating the opening and closing of a plurality of sheet shutters, and a sheet shutter opening and closing control system using the multi-remote controller. [Background technology]

[0002] Sheet shutters are installed in buildings such as factories and warehouses, and allow for the quick opening and closing of entrances and exits when loading and transport vehicles enter and exit, thereby reducing the time required to pass through the entrance and improving work efficiency. They also improve air conditioning efficiency by minimizing the influence of the external environment on the indoor environment, and their increased dust and insect resistance helps maintain a cleaner indoor environment.

[0003] Among such sheet shutters, there has been proposed a system in which multiple sheet shutters are installed in the same building and the specifications of the sheet shutters to be opened and closed are changed accordingly based on environmental conditions such as wind speed, air pressure, smell, smoke, sunlight, or temperature. There has also been proposed a system in which multiple sheet shutters are installed on the route to and from a building, and when one of the sheet shutters is opened, the others are closed (see Patent Document 1). Such sheet shutters can more effectively prevent the influence of the external environment from reaching the interior. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-158292 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, sheet shutters, which are mainly installed in buildings such as factories and warehouses, are sometimes passed by while riding on loading and transport vehicles such as forklifts. If the switch for opening and closing the sheet shutter is installed on the wall of the building, it is necessary to get off the vehicle to open the sheet shutter, which is inefficient.

[0006] Therefore, it is conceivable to use a remote controller as the switch for opening and closing the sheet shutters, but if a large number of sheet shutters are installed, a large number of remote controllers will also be required, which will be cumbersome to manage and it will be difficult for the driver of the loading and transport vehicle to operate a large number of remote controllers, each different for each sheet shutter.

[0007] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a multi-remote controller that can quickly and easily operate the opening and closing of a plurality of sheet shutters, and a sheet shutter opening and closing control system that uses the multi-remote controller. [Means for solving the problem]

[0008] The multi-remote controller of the present invention is a multi-remote controller capable of operating the opening and closing of a plurality of sheet shutters, and comprises a plurality of operation switches each set as an operation target for each of the plurality of sheet shutters, a first operation surface on which one or more of the plurality of operation switches are provided, a second operation surface formed on the opposite side of the first operation surface on which the remaining operation switches of the plurality of operation switches are provided, an opening / closing control unit that instructs the opening or closing of the sheet shutter that is the operation target of the operation switch in accordance with the operation of the operation switch, and a wireless control unit that wirelessly transmits an opening / closing command instructing the sheet shutter that is the operation target to open or close based on the instruction of the opening / closing control unit.

[0009] The multi-remote controller of the present invention is configured such that each of the operation switches can switch the sheet shutter to be operated, and further includes a changeover switch for switching the sheet shutter to be operated by the operation switch to another sheet shutter.

[0010] The multi-remote controller of the present invention further includes a switch display unit that displays a state in which the operation target of the operation switch has been switched by the changeover switch.

[0011] The seat shutter opening / closing control system of the present invention is a seat shutter opening / closing control system comprising the above-mentioned multi-remote controller and a plurality of seat shutters that are operated to open and close by the multi-remote controller, wherein an identification element is displayed for each operation switch, a first display element corresponding to the identification element is displayed on the seat shutter that is the object of operation by the operation switch, and a second display element corresponding to the display on the switching display unit is further displayed on the seat shutter.

[0012] In the sheet shutter opening / closing control system of the present invention, the identification element and the first display element are letters or numbers, the switching display unit is an illuminant that indicates that the operation target has been switched by changing the color of the light it emits, and the second display element is a color displayed on the sheet shutter.

[0013] In the sheet shutter opening / closing control system of the present invention, the multi-remote controller has three operation switches arranged on each of the first operation surface and the second operation surface, and each operation switch displays a different identification element, and the corresponding first display element is displayed on the sheet shutter corresponding to the operation switch.

[0014] The sheet shutter opening / closing control system of the present invention comprises a multi-remote controller formed by providing three switch placement holes on both sides of a hollow case having two sides, in which the operation switches are placed, and further comprises a single-point remote controller formed using the same case as the multi-remote controller and having a closing body for closing two of the switch placement holes formed on at least one side, and having a single-point operation surface on which one single-point operation switch is placed, and the single-point operation switch of the single-point remote controller is set to operate one sheet shutter.

[0015] The sheet shutter opening / closing control system of the present invention is configured such that the multi-remote controller is formed by providing three switch placement holes on both sides of a hollow case having two sides, in which the operation switches are placed, and further includes a three-point remote controller formed using the same case as the multi-remote controller, and in which an up switch corresponding to raising the sheet shutter to be operated, a down switch corresponding to lowering the sheet shutter to be operated, and a stop switch corresponding to stopping the sheet shutter to be operated are placed in the switch placement holes formed on at least one side.

[0016] In the sheet shutter opening / closing control system of the present invention, the multi-remote controller further has an output section capable of outputting warning information or position information. [Effects of the Invention]

[0017] According to the multi-remote controller of the present invention, the multi-remote controller includes a plurality of operation switches, each of which is set to operate a plurality of sheet shutters, so that the plurality of sheet shutters can be operated with a single multi-remote controller. The plurality of operation switches are arranged on a first operation surface and a second operation surface formed on the opposite side of the first operation surface, so that the plurality of operation switches can be arranged on the multi-remote controller without increasing the size of the multi-remote controller or reducing the size of the operation switches. The multi-remote controller includes an opening / closing control unit that instructs the sheet shutters operated by the operation switches to open or close in response to the operation of the operation switches, and a wireless control unit that wirelessly transmits opening / closing commands to the sheet shutters to be operated based on the instruction from the opening / closing control unit. This allows the plurality of sheet shutters to be opened and closed with a relatively simple operation, improving operability, for example, when operating a loading / transporting vehicle such as a forklift or when wearing gloves.

[0018] In the multi-remote controller of the present invention, the sheet shutters to be operated by the operation switches can be switched using a changeover switch, so the number of sheet shutters to be operated that can be assigned to one operation switch can be increased to two or more. Therefore, there is no need to change the size of the multi-remote controller or the operation switches, so it is possible to operate more sheet shutters with one multi-remote controller without reducing operability.

[0019] According to the multi-remote controller of the present invention, a switching display unit is further provided which displays the state in which the operation target of the operation switch has been switched by the changeover switch, so that it is possible to easily recognize which sheet shutter is the operation target of the operation switch by checking the state displayed on the switching display unit.

[0020] According to the seat shutter opening / closing control system of the present invention, the multi-remote controller displays an identification element for each operation switch, and also displays a first display element corresponding to the identification element on the seat shutter that is the target of operation by that operation switch, and further displays a second display element corresponding to the display on the switching display unit, so that when opening or closing the seat shutter, the corresponding operation switch can be intuitively recognized, making the opening and closing operation of the seat shutter easier.

[0021] According to the seat shutter opening / closing control system of the present invention, the identification element and the first display element are letters or numbers, the switching display unit of the multi-remote controller is an illuminant that indicates the switching of the operation target by changing the light color, and the second display element is a color displayed on the seat shutter, so that the first display element and the second display element can be easily displayed in the same area and the person operating the seat shutter to open or close can easily recognize the operation switch to be operated.

[0022] According to the sheet shutter opening / closing control system of the present invention, three operation switches are arranged on each of the first operation surface and the second operation surface of the multi-remote controller, and each operation switch displays a different identification element, so that six different sheet shutters can be opened and closed with one multi-remote controller.

[0023] According to the sheet shutter opening / closing control system of the present invention, the single-point remote controller formed using the same case as the multi-remote controller has a closing body that closes two of the three switch placement holes on one side, and a single-point operation surface is formed on which one single-point operation switch is placed.Therefore, by forming the multi-remote controller and the single-point remote controller using the same case, the number of parts can be reduced, leading to cost savings.

[0024] According to the sheet shutter opening / closing control system of the present invention, the three-point remote controller formed using the same case as the multi-remote controller has the up switch, down switch, and stop switch arranged in the three switch arrangement holes on one side, so that when there is no need to operate multiple sheet shutters with one multi-remote controller, for example, the sheet shutters can be operated more easily. Furthermore, by forming the multi-remote controller and the three-point remote controller in the same case, the number of parts can be reduced, thereby cutting costs.

[0025] According to the sheet shutter opening / closing control system of the present invention, the multi-remote controller further has an output unit capable of outputting warning information or position information. For example, when the multi-remote controller moves away from a predetermined range or receives a signal from outside to search for the multi-remote controller, the output unit outputs warning information or position information, thereby preventing the multi-remote controller from being lost or taken away.

[0027] Hereinafter, an embodiment of a multi-remote controller 1 and a sheet shutter opening / closing control system according to the present invention will be described with reference to the drawings. The multi-remote controller 1 of this embodiment is a controller that operates the opening and closing of multiple sheet shutters 2. The sheet shutter opening / closing control system is a system that controls the opening and closing of multiple sheet shutters 2 using the multi-remote controller 1.

[0028] The sheet shutter opening / closing control system of this embodiment comprises a plurality of sheet shutters 2 installed in a building 3, a multi-remote controller 1 that controls the opening / closing of the plurality of sheet shutters 2, and, if necessary, a wireless one-point remote controller 4 and a three-point remote controller 5 that control the opening / closing of one sheet shutter 2.

[0029] [About the sheet shutter] As shown in Figures 1 and 2, a plurality of sheet shutters 2 in this embodiment are provided in a building 3 such as a factory or warehouse. The number of sheet shutters 2 provided in one building 3 is, for example, 18. There is no limit to the number of sheet shutters 2 provided, but as long as there are 18 or fewer, they can be controlled by one multi-remote controller 1 of this embodiment. Within the building 3, a space is formed in which the environment, such as temperature, humidity, cleanliness, etc., is controlled, for example, depending on the manufacturing process in a factory or the goods stored in a warehouse, and the sheet shutters 2 are provided at the entrances and exits to this space.

[0030] As shown in Figures 2 and 3, the sheet shutter 2 has a flexible sheet body 20, a winding drum 21 that is located above the entrance where the sheet shutter 2 is installed and winds up the sheet body 20, a storage box 22 that is installed on the upper edge of the entrance and stores the winding drum 21, an opening / closing drive unit 23 that drives the winding drum 21 to rotate in a forward rotation direction in which the sheet body 20 is wound onto the winding drum 21 and in a reverse rotation direction in which the sheet body 20 is unwound from the winding drum 21, a pair of left and right guide rails 24 that are formed vertically along both side edges and guide the sheet body 20 up and down, and a control box 25 that controls the opening and closing of the sheet shutter 2.

[0031] The sheet body 20 is a rectangular curtain made of a synthetic resin material that is flexible, weather-resistant, and, if necessary, light-transmitting, light-blocking, or insect-repellent. The upper end of the sheet body 20 is attached to the circumferential surface of the winding drum 21 along the axial direction. Guide protrusions (not shown) are provided on the left and right sides of the sheet body 20, and the sheet body 20 is inserted into guide rails 24 and engaged with them so that it can slide up and down. This allows the sheet body 20 to perform smooth lifting and lowering operations while maintaining tension in the width direction.

[0032] The winding drum 21 is stored in a storage box 22 formed at the upper end of the opening, and is rotated about its axis by the rotational drive of an opening / closing drive unit 23, thereby being able to wind and unwind the sheet body 20. The opening / closing drive unit 23 is a motor that can rotate the winding drum 21 in forward and reverse directions. The guide rails 24 have a groove-shaped cross section and are formed vertically along both side edges of the opening, and slidably accommodate guide protrusions (not shown) formed on the left and right sides of the sheet body 20.

[0033] The upper storage box 22 displays a first display element 6 with one Arabic numeral from 1 to 6 on its surface, and a second display element 7 colored red, green, or orange is displayed around the first display element 6. In this embodiment, the first display element 6 and the second display element 7 are installed on the storage box 22 located at the upper edge of the entrance so that they can be seen from as far away as possible. However, this is not limited to this, and they may be installed and displayed in other visible locations, such as the top of the guide rail 24 or a wall surface near the sheet shutter 2. The first display element 6 and the second display element 7 may be located anywhere as long as they are recognizable as elements to identify the seat shutter 2 by pedestrians passing through the entrance where the sheet shutter 2 is installed and drivers of loading and transport vehicles. The first display element 6 and the second display element 7 are visibly arranged on both sides of the storage box 22, facing both sides of the entrance across the sheet shutter 2.

[0034] In this embodiment, the first display elements 6 are Arabic numerals, but the first display elements 6 may be characters such as alphabets, katakana, hiragana, or kanji, or may be words of about two or three characters. The first display elements 6 may be easily identifiable by a person viewing them, and may be recognized in association with identification elements 11 (described later) displayed on the operation switches 10 of the multi-remote controller 1. In this embodiment, the second display elements 7 are colors, but are not limited to these and may be other elements such as letters or numbers.

[0035] The control box 25 has a control unit 28, an operation unit 29, and a communication unit 30. The control box 25 is fixed to the surface of the guide rail 24. The control unit 28 is a processor that can send commands to the opening / closing drive unit 23 to rotate in a forward direction, rotate in a reverse direction, and stop driving. The operation unit 29 is an input interface that performs opening and closing operations of the sheet body 20 of the sheet shutter 2. The communication unit 30 is a communication interface that receives signals from the multi-remote controller 1 and transmits them to the control unit 28, and also outputs commands from the control unit 28 to the opening / closing drive unit 23. The control unit 28 controls the opening / closing drive unit 23 of the sheet shutter 2 based on signals from the multi-remote controller 1, etc., received by the communication unit 30.

[0036] [About the multi-remote controller] As shown in FIGS. 4 to 6 , the multi-remote controller 1 is formed by assembling various components into a hollow case 12 formed in a flat, mochi-shaped configuration. The case 12 is formed by stacking two resin cover bodies 32 on top of each other and fastening them with screws. Each of the two cover bodies 32 has a flat surface, which forms a first operation surface 13 and a second operation surface 14. Three switch placement holes 15 for arranging operation switches 10 are formed on each of the flat surfaces that form the first operation surface 13 and the second operation surface 14. The switch placement holes 15 are vertically offset so that the operation switches 10 on the first operation surface 13 and the second operation surface 14 do not interfere with each other inside the case 12. In addition, one selector switch placement hole (not shown) is formed on each of the flat surfaces on both sides of the multi-remote controller 1. Embossed stickers 16 are attached to the flat surfaces on both sides of the multi-remote controller 1, forming the first operation surface 13 and the second operation surface 14.

[0037] The first operation surface 13 has three operation switches 10 for controlling the opening and closing of the sheet shutters 2 to be operated, one selector switch 17 for switching the sheet shutters 2 targeted by the operation switches 10, a three-color LED switch indicator 18, and a transmission indicator 19 for indicating the status of commands being sent to the sheet shutters 2. The three operation switches 10 are spaced apart from one another in the center of the first operation surface 13, and each operation switch 10 has an Arabic numeral 1 through 3 printed on its surface as an identification element 11. The letters "CH" are printed on the surface of the selector switch 17, indicating that it is a switch for switching channels. The switch indicator 18 can emit light in red, green, or orange, indicating that the selector switch 17 has switched the sheet shutter 2 targeted by the operation switch 10. The transmission indicator 19 indicates the status of an operated operation switch 10 sending an open / close command to the sheet shutter 2 targeted for operation. The transmission indicator 19 is an LED that lights up when any of the operation switches 10 is operated.

[0038] Similar to the first operation surface 13, the second operation surface 14 has three operation switches 10, one changeover switch 17, a changeover display unit 18, and a transmission display unit 19. The functions of each unit on the second operation surface 14 are the same as those on the first operation surface 13, so a description thereof will be omitted. Three operation switches 10 are arranged at intervals from each other in the center of the second operation surface 14, and Arabic numerals 4 to 6 are printed on the surface of each operation switch 10 as identification elements 11. The operation switches 10 on the second operation surface 14 are arranged alternately with the operation switches 10 on the first operation surface 13, and are arranged so that the operation switches 10 do not interfere with each other inside the multi-remote controller 1.

[0039] In this embodiment, the identification elements 11 provided on the surfaces of the operation switches 10 on the first operation surface 13 and the second operation surface 14 are the same numbers as the first display elements 6 written on the surface of the storage box 22 of the sheet shutter 2 to be operated. The identification elements 11 may be characters such as alphabets, katakana, hiragana, or kanji, or may be words of about two to three characters, for example. The identification elements 11 should be easily identifiable by a person who sees them, and should be recognizable in association with the first display elements 6 displayed on the sheet shutter 2 to be operated.

[0040] Six through holes 31 are provided on the second operation surface 14 side of the multi-remote controller 1, and the two cover bodies 32 are combined and fixed together by threading screws through the through holes 31 into the screw holes on the first operation surface 13 side, and the two cover bodies 32 can be separated by removing these screws to perform maintenance such as battery replacement or changing various settings. A strap hole 36 is provided on the edge of the multi-remote controller 1 for hanging a strap or the like.

[0041] Inside the case 12 of the multi-remote controller 1, there are provided an opening / closing control unit 34 that controls changing the settings of the multi-remote controller 1 or controls the transmission of various commands to the wireless control unit 33 based on the pressing of the surfaces of each operation switch 10 and changeover switch 17, the wireless control unit 33 that transmits opening / closing commands to the target sheet shutter 2 based on the control of the opening / closing control unit 34, and a button battery 35 that supplies electricity to the opening / closing control unit 34 and the wireless control unit 33.

[0042] The opening / closing control unit 34 is a circuit board that is screwed into the interior of the multi-remote controller 1. The wireless control unit 33 is mounted on its front surface, and a battery holder for detachably mounting a button battery 35 is fixed on its rear surface. The opening / closing control unit 34 has two LED lamps mounted on its front surface, one of which is the switching display unit 18 and the other is the transmission display unit 19. A light-emitting hole is formed in the case 12 at a position overlapping the switching display unit 18 and the transmission display unit 19, which guides the light emitted from the switching display unit 18 and the transmission display unit 19 to the outside of the multi-remote controller 1. The switching display unit 18 can emit light in red, green, and orange, and the emitted color is sequentially switched by pressing the selector switch 17. When the selector switch 17 is pressed, the switching display unit 18 emits light for, for example, 5 to 30 seconds and then turns off, thereby allowing the operator to recognize the color of the second display element 7 of the sheet shutter 2 to be operated while conserving power consumption. The switching display unit 18 is not limited to a unit that indicates the sheet shutter 2 to be operated by the multi-remote controller 1 by changing the color of the light it emits, but may also be a unit that can changeably display letters, numbers, etc.

[0043] The opening / closing control unit 34 is provided with a pressure-sensing unit 37 at the position where the operation switch 10 and the changeover switch 17 are disposed, which detects the pressing operation of the operation switch 10 and the changeover switch 17. Based on the detection by the pressure-sensing unit 37, the opening / closing control unit 34 determines the pressing operation of the operation switch 10 and the changeover switch 17 and controls each unit.

[0044] Although not shown, the multi remote controller 1 is formed using the same opening / closing control unit 34 as the one-point remote controller 4 and three-point remote controller 5 described later, and the opening / closing control unit 34 is provided with a mode changeover switch (not shown), which is a slide switch that can change between three modes: a multi mode for operating multiple sheet shutters 2 with one multi remote controller 1, a one-point mode for use as the one-point remote controller 4, and a three-point mode for use as the three-point remote controller 5. The opening / closing control unit 34 also has a lighting setting switch (not shown) that changes the setting for the lighting time of the switching display unit 18. An antenna connected from the wireless control unit 33 is also wired to the opening / closing control unit 34.

[0045] The wireless control unit 33 is a microcomputer board that controls wireless communication. The wireless control unit 33 is capable of communication on 18 or more different frequency channels. A different channel is set for each sheet shutter 2 with which it communicates. Three channels are assigned to each of the six operation switches 10 provided on the multi-remote controller 1, and the multi-remote controller 1 as a whole can transmit on 18 channels. One of these 18 channels is assigned to the control box 25 of each sheet shutter 2.

[0046] The multi remote controller 1 may be provided with a built-in output device 38 capable of outputting location information, such as a GPS tracker or a smart tag using a network such as Bluetooth (registered trademark), so that the location information can be confirmed from an external terminal connected to the Internet. That is, the multi remote controller 1 may output location information onto the Internet using the built-in output device 38, and an external terminal may access the location information to confirm the location of the multi remote controller 1.

[0047] Furthermore, the multi remote controller 1 may output warning information when it determines that it has left a predetermined distance range using the built-in output device 38. Specifically, a device such as a router capable of connecting via Wi-Fi (registered trademark) or Bluetooth (registered trademark) is installed in the building 3 in which the sheet shutter 2 is installed, and the device is wirelessly connected to the output device 38. When the connection between the output device 38 and the device is terminated, the multi remote controller 1 determines that it has left the predetermined distance range, and the output device 38 outputs warning information. The warning information may be, for example, a beep sound, or may be a message displayed on a predetermined terminal via a network to indicate that the multi remote controller 1 has left the predetermined range.

[0048] As described above, according to the sheet shutter opening / closing control system of this embodiment, when the multi remote controller 1 moves away from a predetermined distance range or when a signal to search for the multi remote controller 1 is received from outside, the output device 38 outputs warning information or position information, thereby preventing the multi remote controller 1 from being lost or taken away. Note that the "output unit" in the present invention corresponds to the output device 38 in this embodiment.

[0049] For example, when the number of sheet shutters 2 installed in a building 3 is small, it may be more convenient to use a controller that opens and closes only one sheet shutter 2 rather than using the above-mentioned multi-remote controller 1. In the above case, the sheet shutter opening and closing control system uses a one-point remote controller 4 or a three-point remote controller 5.

[0050] [About the single-point remote controller] 7 and 8, the single-point remote controller 4 is formed using the same case 12 as the multi-remote controller 1. The single-point remote controller 4 has embossed stickers 16 attached to the flat surfaces on both sides, forming a single-point operation surface 41 and a non-operation surface 42.

[0051] The single-point operation surface 41 has one single-point operation switch 40 that controls the opening and closing of the sheet shutter 2, and a transmission display unit 19 that shows the state in which a command is being sent to the sheet shutter 2. Specifically, of the three switch placement holes 15 formed on the plane that forms the single-point operation surface 41, the central hole is the single-point operation switch 40, and the two switch placement holes 15 adjacent to the central hole are closed with stickers 16 attached. The words "OPEN / CLOSE" are displayed on the single-point operation switch 40. A selector switch placement hole (not shown) is also closed with a sticker 16 attached. In addition, a light-emitting hole at the position where the switch display unit 18 is to be formed is also closed with a sticker 16 attached, and light from the transmission display unit 19 is guided to the outside of the multi-remote controller 1 through the light-emitting hole.

[0052] The non-operation surface 42 has three switch placement holes 15, a changeover switch placement hole (not shown), and two light-emitting holes all covered with a seal 16, forming a flat surface that does not have any switches or display units.

[0053] The single-point remote controller 4 is provided with an opening / closing control unit 34, a wireless control unit 33, and a button battery 35 inside the case 12, similar to the multi-remote controller 1 described above. The opening / closing control unit 34 is the same board as the board provided inside the multi-remote controller 1, with the wireless control unit 33 mounted on the front surface and a battery holder for detachably attaching the button battery 35 fixed on the back surface. The opening / closing control unit 34 has the same configuration as the opening / closing control unit 34 built into the multi-remote controller 1, so a detailed description will be omitted. The opening / closing control unit 34 is arranged with a mode selector switch (not shown) switched to single-point mode. One channel of the wireless control unit 33 is assigned to the single-point operation switch 40 of the single-point remote controller 4, and the wireless control unit 33 is capable of wireless connection with the control box 25 of one sheet shutter 2.

[0054] [Regarding the 3-point remote controller] 9, the three-point remote controller 5 is formed using the same case 12 as the multi-remote controller 1. Embossed stickers 16 are attached to the flat surfaces on both sides of the three-point remote controller 5, forming a three-point operation surface 50 and a non-operation surface 42.

[0055] The three-point operation surface 50 has an up switch 51 for raising the sheet body 20 of the sheet shutter 2 to be operated, a down switch 52 for lowering the sheet body 20 of the sheet shutter 2 to be operated, a stop switch 53 for stopping the sheet body 20 of the sheet shutter 2 to be operated, and a transmission display unit 19 for indicating the state in which a command is being sent to the sheet shutter 2. Specifically, three switch placement holes 15 formed on the plane that forms the three-point operation surface 50 respectively serve as the up switch 51, the down switch 52, and the stop switch 53. The changeover switch placement holes (not shown) are closed with a sticker 16 attached. In addition, a light-emitting hole at the position where the changeover display unit 18 is to be formed is also closed with a sticker 16 attached, and light from the transmission display unit 19 is guided to the outside of the multi-remote controller 1 through the light-emitting hole.

[0056] The non-operation surface 42 has three switch placement holes 15, a changeover switch placement hole (not shown), and two light-emitting holes all covered with a seal 16, forming a flat surface that does not have any switches or display units.

[0057] The three-point remote controller 5 is provided with an opening / closing control unit 34, a wireless control unit 33, and a button battery 35 inside the case 12, similar to the multi-remote controller 1 described above. The opening / closing control unit 34 is the same board as the board provided inside the multi-remote controller 1, with the wireless control unit 33 mounted on the front surface and a battery holder for detachably attaching the button battery 35 fixed on the back surface. The opening / closing control unit 34 has the same configuration as the opening / closing control unit 34 built into the multi-remote controller 1, so a detailed description will be omitted. The opening / closing control unit 34 is arranged with a mode selector switch (not shown) switched to three-point mode. The wireless control unit 33 assigns the same channel to the up switch 51, down switch 52, and stop switch 53 of the three-point remote controller 5, and is capable of wireless connection with the control box 25 of one sheet shutter 2.

[0058] In this way, the one-point remote controller 4 and the three-point remote controller 5 can be formed using the same case 12 and the same board by simply replacing the seal 16 with that of the multi-remote controller 1, which contributes to reducing the number of parts and costs.

[0059] [Processing of the switching control unit] Next, referring to Fig. 10, a process performed mainly by the opening / closing control unit 34 of the multi-remote controller 1, the single-point remote controller 4, or the three-point remote controller 5 in the sheet shutter opening / closing control system will be described. The opening / closing control unit 34 first determines whether the state of the controller is in the multi-mode (S100). Specifically, the opening / closing control unit 34 determines whether the mode changeover switch mounted on the opening / closing control unit 34 is slid to the multi-mode position. If it is determined that the controller is in the multi-mode (S100: YES), the controller is the multi-remote controller 1, and the process then proceeds to step S101.

[0060] In step S101, the open / close control unit 34 determines whether the changeover switch 17 has been pressed (S101). If it is determined that the changeover switch 17 has been pressed (S101: YES), then a channel switching process is performed (S102). That is, as shown in FIG. 11, three frequency channels are pre-assigned to each of the six operation switches 10 of the multi-remote controller 1, and when each operation switch 10 is pressed, a process is performed to change the communication frequency at which an open / close command is output. After the channel switching process is performed (S102), the switching display unit 18 is then caused to emit light in a color indicating the switched channel (S103), and the process ends. The light emission time of the switching display unit 18 is pre-set in the open / close control unit 34.

[0061] Returning to step S101, if it is determined that the changeover switch 17 has not been pressed (S101: No), it is then determined whether any of the operation switches 10 have been pressed (S104). If it is determined that an operation switch 10 has been pressed (S104: YES), the wireless control unit 33 is instructed to transmit an open / close command on the frequency channel currently set for the pressed operation switch 10 (S105). If it is determined that no operation switch 10 has been pressed (S104: No), the multi remote controller 1 can determine that no operation has been accepted, and therefore ends the process.

[0062] Returning to step S100, if it is determined that the mode is not the multi-point mode (S100: No), it is next determined whether the mode is the single-point mode (S106). Specifically, it is determined whether the mode changeover switch mounted on the opening / closing control unit 34 is slid to the single-point mode position. If it is determined that the mode is the single-point mode (S106: YES), the controller is the single-point remote controller 4, and the process then proceeds to step S107.

[0063] In step S107, it is determined whether the one-point operation switch 40 has been pressed (S107). If it is determined that the one-point operation switch 40 has been pressed (S107: YES), the wireless control unit 33 is instructed to transmit an open / close command on the set frequency channel (S108). If it is determined that the one-point operation switch 40 has not been pressed (S107: NO), the process ends immediately.

[0064] Returning to step S106, if it is determined that the mode is not the one-point mode (S106: No), the controller is a three-point remote controller 5, and the process then proceeds to step S109.

[0065] In step S109, it is determined whether the up switch 51 has been pressed (S109). If it is determined that the up switch 51 has been pressed (S109: YES), the wireless control unit 33 is instructed to transmit a command to raise the seat body 20 on the set frequency channel (S110).

[0066] If it is determined in step S109 that the up switch 51 has not been pressed (S109: No), it is then determined whether the down switch 52 has been pressed (S111). If it is determined that the down switch 52 has been pressed (S111: YES), the wireless control unit 33 is instructed to transmit a command to lower the sheet 20 on the set frequency channel (S112).

[0067] If it is determined in step S111 that the down switch 52 has not been pressed (S111: No), it is then determined whether the stop switch 53 has been pressed (S113). If it is determined that the stop switch 53 has been pressed (S113: YES), the wireless control unit 33 is instructed to transmit a command to stop the shutter on the set frequency channel (S114). If it is determined in step S113 that the stop switch 53 has not been pressed (S113: No), the process ends immediately.

[0068] [Operator operation] Next, we will explain how a person who passes through an entrance where the sheet shutter 2 is installed operates the multi-remote controller 1. When opening or closing the sheet shutter 2, first, the person visually checks the first display element 6 and the second display element 7 printed on the surface of the storage box 22 of the sheet shutter 2. The first display element 6 is a number, and the second display element 7 is the color of the area around the first display element 6, so they can be visually checked very easily.

[0069] The changeover switch 17 of the multi-remote controller 1 is pressed down to check the frequency channel set in the multi-remote controller 1. Specifically, the changeover switch 17 is pressed down to check the lighting color of the changeover display unit 18, thereby checking the frequency channel set in the multi-remote controller 1. Then, the changeover switch 17 is continued to be pressed down until the lighting color of the changeover display unit 18 becomes the same color as the second display element 7 displayed on the storage box 22 of the sheet shutter 2. When the lighting color of the changeover display unit 18 becomes the same color as the second display element 7, the operation switch 10 of the multi-remote controller 1, on which the identification element 11 having the same number as the first display element 6 on the storage box 22 is displayed, is pressed down.

[0070] When the operation switch 10 is pressed, the wireless control unit 33 of the multi-remote controller 1 transmits an open / close command, which is received by the communication unit of the control box 25 of the sheet shutter 2. When the communication unit receives the open / close command while the sheet shutter 2 is closed or stopped midway through opening or closing, the control unit 28 of the control box 25 transmits a command to the open / close driver to drive it in the forward direction. The open / close driver 23 rotates the winding shaft 21 in the forward direction, thereby winding the sheet body 20 onto the winding shaft 21 and opening the sheet shutter 2.

[0071] In this way, by switching the lighting color of the switching display section 18 based on the second display element 7 of the seat shutter 2, and determining the identification element 11 of the operation button to be pressed based on the first display element 6 of the seat shutter 2 and pressing it, an open / close command can be sent from the multi-remote controller 1 on the frequency channel set for the seat shutter 2 to be operated, as shown in Figure 11.

[0072] When the communication unit receives an open / close command while the sheet shutter 2 is open, the control unit 28 of the control box 25 sends a command to the open / close drive unit to drive it in reverse rotation. The open / close drive unit 23 rotates the winding shaft 21 in the reverse rotation direction, whereby the sheet body 20 is unwound from the winding shaft 21 and the sheet shutter 2 is closed.

[0073] When the communication unit receives an opening / closing command while the sheet shutter 2 is opening or closing, the control unit 28 of the control box 25 sends a command to the opening / closing drive unit to stop it. The opening / closing drive unit 23 stops the rotation of the winding shaft 21, thereby stopping the sheet body 20 in the middle of rotation.

[0074] In this way, the first display element 6 and the second display element 7 displayed on the storage box 22 of the sheet shutter 2 can be easily confirmed, and by simply operating in accordance with the lighting color of the switching display section 18 of the multi-remote controller 1 and the identification element 11 of the operation switch 10, the desired sheet shutter 2 can be opened or closed from among a large number of sheet shutters 2. Therefore, there is no need to carry a separate remote controller for each sheet shutter 2, and intuitive and quick opening and closing operations of the sheet shutters 2 can be performed, which allows smooth passage of, for example, loading and transport vehicles.

[0075] Moreover, the multi remote controller 1 is provided with a first operation surface 13 and a second operation surface 14, and an operation switch 10 is provided on each operation surface. By distributing the operation switches 10 between the two surfaces, the number of operation switches 10 provided on one surface can be reduced, and many operation switches 10 can be provided on the multi remote controller 1 without increasing the size of the multi remote controller 1 or reducing the size of the operation switches 10. In particular, by providing the changeover switch 17, three frequency channels can be assigned to one operation switch 10, so that one operation switch 10 can open and close three sheet shutters 2. In this embodiment, one multi remote controller 1 can operate 18 sheet shutters 2. In addition, it is only necessary to provide three operation switches 10 on the first operation surface 13 and the second operation surface 14 of the multi remote controller 1. Therefore, by not increasing the number of operation switches 10 provided on one surface, for example, a driver of a loading and transport vehicle can operate the multi remote controller 1 while wearing gloves, thereby improving operability.

[0076] When opening and closing the sheet shutter 2 using the one-point remote controller 4 or the three-point remote controller 5, the sheet shutter 2 and the one-point remote controller 4 or the three-point remote controller 5 are paired (connected) in advance, and a specific sheet shutter 2 is opened and closed by operating the one-point remote controller 4 or the three-point remote controller 5.

[0077] It goes without saying that the embodiments of the present invention are not limited to the above-described embodiments, and can be modified as appropriate without departing from the scope of the concept of the present invention. [Industrial Applicability]
