Abstract

To prevent a non-contact operator from erroneously detecting an operating motion of a contact-type operator even when the contact-type operator and the non-contact operator are provided on a same operation panel.SOLUTION: An area sensor 291 is arranged near a push button 241 corresponding to an opening operation of a contact-type operator, and an area sensor 292 is arranged at a position that is away from an arrangement position of the contact-type operator and at which a finger 40 while press-operating a push button 24 would not be detected. An open signal or a close signal is output depending on the time from when the area sensor 291 detects the finger until it becomes non-detected. When the time for which the area sensor 291 has detected the finger is a predetermined time (for example, 1 seconds) or more and if the movement of the finger in the opening direction is detected, the open signal is output, while if the movement of the finger in the closing direction is detected, the close signal is output.SELECTED DRAWING: Figure 6

Description

[Technical field]

[0001] The present invention relates to an input / output terminal block device, a switching device, and an opening / closing control method for a switching device configured to separate openings in structural bodies including buildings such as buildings, factories, and warehouses using opening / closing bodies such as shutters, and in particular to an input / output terminal block device, a switching device, and an opening / closing control method for controlling each switching operation using both a contact type operator and a non-contact type operator. [Background technology]

[0002] An opening and closing device such as a shutter curtain is installed in an opening or window of a structural body including a house, a building, a factory, a warehouse, a garage, or the like, or in an opening of an internal passage or space, and opens or closes the opening by moving the opening and closing body. This opening and closing device is configured to unfold and lower an opening and closing body such as a slat curtain made of many rectangular slat materials, a pipe grill curtain made of many pipe materials connected with a link material, a panel curtain made of a single panel material or a panel material connected with many panels, a net curtain made of a net material, a sheet curtain made of a sheet material made of synthetic resin or cloth fiber, or a composite curtain made of a composite material of these materials, from the top of the opening and closing the entire opening. In such an opening and closing device, the opening and closing operation of the opening and closing body is often performed electrically. Examples of electrically operated opening and closing devices include an electric shutter device, an electric door device, and an electric awning device.

[0003] These electric opening and closing devices are mainly configured so that the motor drive (inverter), input / output terminal block, parameter setting unit, etc., required for controlling the opening and closing of the opening and closing body, are housed in one control panel. Figure 1 is a front view showing the schematic configuration of a conventional roller screen device. The roller screen device 10 is composed of a storage box 11, guide rails 12 and 13, a winding shaft 14, a screen curtain 15, a weight bar 16, etc.

[0004] The winding shaft 14 is rotatably attached between a bearing portion (not shown) and a roll end portion (not shown) provided on the inner wall surfaces on both the left and right sides inside the storage box 11. One end of the screen curtain 15 is attached to the winding shaft 14, and a weight bar 16 is attached to the other end, so that the screen curtain 15 is guided into a slit-shaped entrance provided at the lower end of the storage box 11. Therefore, the screen curtain 15 is wound up on the winding shaft 14 in accordance with the rotation of the winding shaft 14, and is unwound from the slit-shaped entrance.

[0005] The winding shaft 14 has a hollow pipe shape, and its rotation is controlled by the driving force of the electric motor 17 inserted into this hollow portion. Although not shown, the outside of the body of the electric motor 17 is fixed to the inside of the winding shaft 14, and the output shaft of the electric motor 17 is fixed to the bearing portion with bolts or the like so as not to rotate. Therefore, when the electric motor 17 rotates in the forward direction, the screen curtain 15 operates to be unrolled, and when the electric motor 17 rotates in the reverse direction, the screen curtain 15 operates to be wound up. In other words, the opening and closing operation of the screen curtain 15, which is the opening and closing body, is controlled by rotating the motor in the forward and reverse directions.

[0006] The opening and closing operation of the screen curtain 15 is controlled by a control panel 20 attached to the right wall of the guide rail 13. The control panel 20 is configured with a microcomputer, and is supplied with an AC voltage of 200 [V] or 100 [V] from the outside via a power line. The control panel 20 is usually composed of an input / output terminal block, a parameter setting unit, etc., and a motor drive board. A three-point push button 33 and the like are connected to the input / output terminal block, and a microcomputer that controls the overall operation of the roller blind device 10 is built in. The parameter setting unit displays and changes parameters for various processing modes, and displays the change history. The motor drive board controls the rotation of the electric motor 17.

[0007] Conventionally, the opening and closing operations of the screen curtain 15 are controlled by operating the push button 33 connected to the input / output terminal block as described above. Meanwhile, Patent Document 1 discloses a non-contact switch for automatic doors that outputs a control signal for opening and closing the automatic door simply by placing a finger nearby.

[0008] The non-contact switch for automatic doors described in Patent Document 1 is suitable for food factories, hospitals, and other places where hygiene is important. However, the non-contact switch for automatic doors described in Patent Document 1 automatically opens the door by holding a finger over the switch, and then automatically closes it. Instead of detecting people approaching the automatic door using a near-infrared reflection method or the like, the non-contact switch merely opens and closes the door automatically in response to the action of holding a finger over the switch. Therefore, even if the non-contact switch for automatic doors described in Patent Document 1 is used to perform opening and closing operations similar to those of a three-point push button provided on a shutter device, it is not possible to arbitrarily control each of the opening and closing operations. In view of this, the applicant of the present application has proposed the invention described in Patent Document 2 as an opening / closing device and an opening / closing control method capable of controlling each opening / closing operation of an opening / closing body by using a non-contact switch.

[0009] Fig. 2 is a diagram showing the schematic configuration of an operation panel incorporating a contact-type push button and a non-contact-type switch. The operation panel in Fig. 2 corresponds to the input / output terminal block 21 proposed in Patent Document 2. The input / output terminal block (operation panel) 21 is configured with the parameter setting unit, push button, and non-contact switch of Fig. 1 built in. This input / output terminal block 21 is equipped with a contact-type parameter setting unit 23, a three-point contact-type push button 24, and a non-contact-type switch (non-contact switch) 25. The input / output terminal block 21 is provided on the front side of the guide rail 13, in a position that is easy for the operator to operate when entering the opening.

[0010] The three-point push button 24 has an up (open) button 241, a stop (stop) button 242, and a down (close) button 243 as control switches corresponding to the opening and closing operations, and outputs control signals (up (open) signal, stop (stop) signal, down (close) signal) according to the operating state of each push button 24 to the microcomputer of the input / output terminal block 21 via a communication cable.

[0011] Non-contact switch 25 is composed of area sensors 25a-25c provided adjacent to the left side of up (open) button 241, stop (stop) button 242, and down (close) button 243 of three-point push button 24. The three area sensors 25a-25c are arranged near the left side of each button along the arrangement direction of three-point push button 24 (the up-down direction or the open-close direction in FIG. 5). This non-contact switch 25 is composed of near-infrared distance-limited reflective area sensors 25a-25c, which detect a state in which a reflective object such as a finger 40 shown by a dotted line approaches area sensors 25a-25c, and output the detection signal to the microcomputer of input / output terminal block 21 via a communication cable. The detection ranges of the area sensors 25a to 25c are areas A, B, and C to the left of the up (open) button 241, the stop (stop) button 242, and the down (close) button 243, and are approximately 5 to 15 cm in front of the sensors.

[0012] The area sensors 25a to 25c detect the presence of a finger 40 when the finger 40 is located in the areas (areas) A, B, and C indicated by dotted lines. The input / output terminal block 21, to which a detection signal is input from the non-contact switch 25 composed of the area sensors 25a to 25c, executes detection signal processing based on the detection signal. This detection signal processing is processing to detect a state equivalent to that in which the up (open) button 241, the stop (stop) button 242, and the down (close) button 243 of the three-point push button 24 are operated, based on the detection signal output from the non-contact switch 25 in response to the movement of the finger 40. The distance between the areas (areas) A, B, and C is such that, when the finger 40 is of a standard adult size, the finger 40 can be held over two areas A and B or areas B and C at the same time, but one finger 40 cannot be held over three areas A to C at the same time. That is, two adjacent area sensors 25a and 25b, and two adjacent area sensors 25b and 25c are disposed at positions spaced apart from each other so that one finger 40 can be detected simultaneously.

[0013] The parameter setting unit 23 includes a parameter display section 231, an enter switch 232, a mode selection switch 233, and scroll switches 234, 235. When the scroll switches 234, 235 are operated, the parameters displayed on the display screen of the parameter display section 231 move up and down, so that the parameter whose setting is desired to be changed is displayed, and by operating the enter switch 232 while the character of the parameter is displayed in inverted, the corresponding parameter can be changed in setting, and all the set values ​​that can be set for the parameter whose setting is to be changed are displayed. In this state, the scroll switches 234, 235 are further operated to move the displayed set values ​​that can be set up up and down to select the desired setting value, and the enter switch 232 is operated, so that the set value of the parameter whose setting is to be changed is selected and set as a new parameter. [Patent Document 1] JP 2008-159293 A [Patent Document 2] JP 2017-095940 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0014] 2 detects the presence or movement of a finger, so when a finger is to press any of the up (open) button 341, the stop (stop) button 342, or the down (close) button 343 of the three-point push button 34, the non-contact switch 25 may erroneously detect the action of the finger when the button is pressed before the button is operated. That is, since the non-contact switch 25 and the three-point push button 34 are arranged adjacent to each other on the input / output terminal block 21, which is the operation panel, the non-contact switch 25 may erroneously detect the action of the finger when the button is operated, even if the push button 34 is operated.

[0015] The present invention has been made in consideration of the above-mentioned points, and aims to provide an input / output terminal block device, an opening / closing device, and an opening / closing control method that are configured so that the non-contact operator does not erroneously detect the operating action of a contact operator, even when a contact operator and a non-contact operator are provided on the same operation panel. [Means for solving the problem]

[0016] A first feature of the input / output terminal block device of the present invention is that it is an input / output terminal block device comprising a contact-type operator means consisting of a push button for instructing the operation of an opening / closing means which opens and closes by dividing a space, and a non-contact type operator means consisting of an area sensor means which corresponds to the contact-type operator means and detects the approach of a finger in a non-contact manner, wherein the open area sensor means corresponding to the opening operation of the non-contact type operator means is disposed in the vicinity of the push button which corresponds to the opening operation of the contact-type operator means, and the closed area sensor means corresponding to the closing operation of the non-contact type operator means is disposed in a position spaced away from the position of the contact-type operator means so as not to detect a finger pressing the contact-type operator means. Since the opening and closing operation of the opening / closing means is controlled based on the operation state of the push button which is the contact type operating means and the detection state of the area sensor means which is the non-contact type operating means, if the contact type operating means and the non-contact type operating means are provided on the same operation panel, there is a possibility that the non-contact type operating means may erroneously detect the operation of the contact type operating means when the operator performs or attempts to perform the operation of the contact type operating means. Therefore, in this invention, the open area sensor means corresponding to the open operation of the non-contact type operating means is disposed near the push button which corresponds to the open operation of the contact type operating means, and the close area sensor means corresponding to the close operation of the non-contact type operating means is disposed at a position away from the arrangement position of the contact type operating means so as not to detect the finger pressing the contact type operating means. This makes it possible to effectively prevent erroneous detection of the non-contact type operating means even when the operator performs or attempts to perform the operation of the contact type operating means.

[0017] A second feature of the input / output terminal block device of the present invention is that, in the input / output terminal block device described in the first feature, the open area sensor means is arranged above approximately the vertical center of the input / output terminal block device, and the closed area sensor means is arranged near the bottom end of the input / output terminal block device. The position, i.e., the installation location, is specifically set so that the closed area sensor means does not detect the finger pressing the contact type operation device. This minimizes the possibility of the non-contact type operation device making a false detection even when the operator performs an operation on the contact type operation device, and effectively prevents false detection.

[0018] A third feature of the input / output terminal block device of the present invention is that, in the input / output terminal block device described in the first or second feature, the open area sensor means is arranged above approximately the vertical center of the input / output terminal block device, and the closed area sensor means is arranged near the bottom end of the input / output terminal block device. This is a specific location where the closed area sensor means is located so that it does not detect the finger pressing the contact type operator means. This makes it possible to minimize the possibility of the non-contact type operator being erroneously detected when the operator operates the contact type operator.

[0019] A fourth feature of the input / output terminal block device of the present invention is that it is an input / output terminal block device comprising a contact-type operator means consisting of a push button for instructing the operation of an opening / closing means which performs an opening and closing operation by dividing a space, and one non-contact type operator means which detects the approach of a finger without contact, and outputs an open signal regarding the opening operation of the opening / closing means or a close signal regarding the closing operation of the opening / closing means depending on the time from when the non-contact type operator means detects the finger to when it becomes non-detection. By the action of the operator holding his / her finger over the non-contact type operating means, the non-contact type operating means can measure the time from when the finger is detected until it becomes non-detected. The non-contact type operating means can also detect the direction of movement of the finger in the detected state, whether up, down, left, or right. Therefore, in this invention, the difference in the movement of the operator's finger is detected according to the time from when the non-contact type operating means detects the finger until it becomes non-detected, and an open signal or a close signal is output based on the difference. For example, the non-contact type operating means outputs an open signal when the detection time is 1 second or more and 3 seconds or less, and outputs a close signal when it is longer than 3 seconds. This can reduce the possibility of the non-contact type operating means making a false detection when the operator performs an operation of the contact type operating means.

[0020] A fifth feature of the input / output terminal block device of the present invention is that, in the input / output terminal block device described in the fourth feature, the non-contact type operator means is arranged in the vicinity of a push button corresponding to the opening operation of the contact type operator means. This is a system in which one non-contact type operating means is disposed adjacent to the top, bottom, left or right of the push button (open button) that corresponds to the opening operation. As a result, when an operator tries to press the open button, even if the non-contact type operating means detects the operator's finger before the pressing operation and the opening / closing means executes the opening operation, this is not considered to be a false detection, and the opening operation intended by the operator has been executed.

[0021] A sixth feature of the input / output terminal block device of the present invention is that, in the input / output terminal block device described in the fourth or fifth feature, when the time during which the non-contact type operator means detects the finger is equal to or longer than a first predetermined time and equal to or shorter than a second predetermined time, an open signal regarding the opening operation of the opening / closing means is output, and when the time during which the non-contact type operator means detects the finger becomes longer than the second predetermined time, a close signal regarding the closing operation of the opening / closing means is output. This is so arranged that when the time during which the non-contact type operating device detects the finger is equal to or longer than a first predetermined time (e.g., 1 second) and equal to or shorter than a second predetermined time (e.g., 3 seconds), an open signal relating to the opening operation of the opening / closing device is output, and when the time during which the non-contact type operating device detects the finger is longer than the second predetermined time (3 seconds), a close signal relating to the closing operation of the opening / closing device is output. Also, by lengthening the duration of the detection time for executing the closing operation to the second predetermined time (3 seconds), even if the user unintentionally places a finger over the non-contact type operating device, the opening / closing device will not start the closing operation unless the finger is kept placed over the non-contact type operating device for longer than the second predetermined time (3 seconds), so that the occurrence of an unintentional closing operation can be prevented in advance.

[0022] A seventh feature of the input / output terminal block device of the present invention is that, in the input / output terminal block device described in the fourth or fifth feature, when the time during which the non-contact type operator means has detected the finger is equal to or longer than a first predetermined time and the finger detects movement of the opening / closing means in an opening direction, an open signal regarding the opening operation of the opening / closing means is output, and when the finger detects movement of the opening / closing means in a closing direction, a close signal regarding the closing operation of the opening / closing means is output. This is a device that outputs an open signal for opening the opening / closing means when the non-contact type operating device detects a finger for a first predetermined time (e.g., 1 second) or more and detects that the finger in the detection state is moving in the opening direction of the opening / closing device, and outputs a close signal when it detects that the finger is moving in the closing direction. Also, by waiting for the first predetermined time to elapse while the finger is held over, the device detects the movement of the finger in the opening or closing direction, thereby eliminating false detections when the operator's finger unintentionally moves in the opening or closing direction, and preventing the occurrence of unintentional opening or closing operations.

[0023] An eighth feature of the input / output terminal block device of the present invention is that, in the input / output terminal block device described in any one of the first to seventh features, it is provided with a display means and / or a sound generating means for making the operator recognize that the non-contact type operator means is in a state of detecting the finger. Since the non-contact type operating means is not equipped with an indicator or the like to display the detection state, the current detection state is unclear, and the operator cannot understand whether it is in a detection state or not. Therefore, in this invention, when the finger is in a state where it is effectively detected, the power state display LED or other display means displays that it is in a detection state, and the sound generating means sounds a buzzer or a sound other than a buzzer sound to let the operator know that it is in a detection state. This allows the operator to easily understand how close the finger needs to be to the non-contact type operating means to be in a detection state, and to judge how close the finger needs to be to the non-contact type operating means for it to react.

[0024] A ninth feature of the input / output terminal block device of the present invention is that, in the input / output terminal block device described in the eighth feature, the display means allows the operator to recognize that the non-contact type operator means is detecting the finger by flashing an indicator light means which is lit when the power of the input / output terminal block device is on and turned off when the power is off, and the sound generating means allows the operator to recognize that the non-contact type operator means is detecting the finger by producing a sound of a predetermined volume. This uses an indicator light means such as an LED that lights up when the power is on and goes off when the power is off as a display means for letting the operator know that the non-contact type operating means is in a state of detecting a finger, and this indicator light means flashes when in a detecting state. Also, the sounding means sounds a sound of a predetermined volume, such as a buzzer sound or a sound other than a buzzer sound. This allows the operator to visually and / or audibly know that the non-contact type operating means is in a detecting state.

[0025] A first feature of the opening and closing device according to the present invention is a opening and closing device comprising: an opening and closing means which performs an opening and closing operation by dividing a space; a contact-type operator means consisting of a push button for instructing the operation of the opening and closing means; a non-contact type operator means which corresponds to the contact-type operator means and consists of an area sensor means which detects the approach of a finger in a non-contact manner; and a control means which controls the operation of the opening and closing means in accordance with the operation state of the contact-type operator means and the detection state of the non-contact type operator means, wherein on an input / output terminal block device comprising the contact-type operator means and the non-contact type operator means, an open area sensor means which corresponds to the opening operation of the non-contact type operator means is arranged in the vicinity of the push button which corresponds to the opening operation of the contact-type operator means, and a closed area sensor means which corresponds to the closing operation of the non-contact type operator means is arranged in a position separated from the arrangement position of the contact-type operator means so as not to detect a finger pressing the contact-type operator means.

[0042] A ninth feature of the opening / closing control method of the present invention is that, in the opening / closing control method described in the eighth feature, the display means allows the operator to recognize that the non-contact type operator means is detecting the finger by flashing an indicator light means that lights up when the power supply of the opening / closing control method is on and goes out when the power supply is off, and the sound generating means allows the operator to recognize that the non-contact type operator means is detecting the finger by producing a sound of a predetermined volume.

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0045] A preferred embodiment of an opening and closing device according to the present invention will be described below with reference to the accompanying drawings. Fig. 3 is a front view showing a schematic configuration of a roller screen device, which is an example of an opening and closing device according to the present invention. Fig. 4 is a side view of the roller screen device of Fig. 3, seen from the right side. In this embodiment, a roller screen device that is controlled to open and close vertically (raise and lower) will be described as an example of an opening and closing device.

[0046] This roller blind device 10 is mounted directly on the ceiling above an opening in the structure's framework or indirectly via other members, or mounted directly on an upper beam or indirectly via other members. This roller blind device 10 is composed of a storage box 11, guide rails 12 and 13, a winding shaft 14, a screen curtain 15 made of synthetic fiber fabric, and a weight bar 16. This roller blind device 10 opens at the top and closes at the bottom, and is provided with the storage box 11 on the ceiling or the like above.

[0047] The roller blind device 10 opens and closes the entrance (opening) by winding and unwinding the screen curtain 15, which is made of synthetic fiber fabric (polyester, etc.), on the winding shaft 14. A fastener section is provided on both sides of the screen curtain 15 over its entire length. This fastener section is sandwiched between inner rails provided in the guide rails 12 and 13 and is designed to slide freely in the vertical direction. This fastener section uses an element that is the meshing part of a normal slide fastener (sliding fastener). This fastener section is made of a metal fastener whose element is made of metal such as red brass, aluminum, or nickel silver, a resin fastener whose element is made of coil-shaped polyester resin, or a Vislon fastener whose resin element such as polyacetal is injection-molded into a tape.

[0048] Inner rails are provided within the guide rails 12, 13, but are omitted in the illustration. In Fig. 3, the guide rails 12, 13 are shown as being provided on both sides of the screen curtain 15 over its entire length, but in reality, inner rails are provided within the guide rails 12, 13, and both sides of the curtain fabric are sandwiched within the guide rails 12, 13 so that it can slide freely up and down.

[0049] The winding shaft 14 is rotatably attached between a bearing portion (not shown) and a roll end portion (not shown) provided on the inner wall surface of both the left and right sides of the storage box 11. One end of the screen curtain 15 is attached to the winding shaft 14, and a weight bar 16 is attached to the other end, so that the screen curtain 15 is guided to a slit-shaped entrance provided at the lower end of the storage box 11. Therefore, the screen curtain 15 is wound up on the winding shaft 14 and unwound from the slit-shaped entrance according to the rotation of the winding shaft 14. An abnormality detection sensor (not shown) is attached to the inner wall surface of the storage box 11 to detect an abnormal state when the screen curtain 15 becomes loose inside the storage box 11 during winding.

[0050] An obstacle detection device may be provided at the tip of the closing side of the screen curtain 15. The winding shaft 14 has a hollow pipe shape, and its rotation is controlled by the electric motor 17 inserted into this hollow part. The outside of the body of the electric motor 17 and the inside of the winding shaft 14 are fixed, and the output shaft of the electric motor 17 is fixed to the bearing part by a bolt or the like so as not to rotate. Therefore, when the electric motor 17 rotates in the forward direction, the screen curtain 15 closes (lowers) so as to be unrolled, and when the electric motor 17 rotates in the reverse direction, the screen curtain 15 opens (rises) so as to be wound up. In other words, the opening and closing operation of the screen curtain 15, which is the opening and closing body, is controlled by rotating the electric motor 17 in the forward and reverse directions.

[0051] In this embodiment, the opening and closing device that controls the drive of the electric motor 17 of the roller blind device 10 is composed of an input / output terminal block 21, a motor drive board 22, and a parameter setting unit 23. The input / output terminal block 21 is configured as a microcomputer, and is supplied with an AC voltage of 200 [V] or 100 [V] from the outside via a power line (not shown), converts the AC voltage to a DC voltage of 24 [V], and supplies it to the motor drive board 22 via a power cable.

[0052] To the input / output terminal block 21, various components such as a three-point push button as a contact type operator, a buzzer, a pull switch, a start sensor, a signal light, a rotating light, various sensors (such as a photoelectric sensor for detecting an obstacle), and a control circuit for a remote control are connected. The input / output terminal block 21 has a built-in microcomputer that controls the overall operation of the roller blind device 10, and executes processing according to a predetermined processing mode based on a control signal corresponding to the operation state of the push button and a signal from the motor drive board 22, and controls the rotation of the electric motor 17. The input / output terminal block 21 has built-in memory and the like that stores a program for executing the processing mode and various parameters required for executing the processing. The input / output terminal block 21 has a built-in parameter setting unit 23, and can execute the setting and changing of parameters for various processing modes based on a parameter setting signal or a change signal. The value set as a parameter is a numerical value or a non-numerical value (for example, a character string or a symbol that specifies the processing mode content) depending on the use of the parameter.

[0053] The input / output terminal block 21 with the built-in parameter setting unit 23 is disposed on the flat portion on the front side of the guide rail 13. In this specification, the front side of the guide rail 12 is the direction toward the viewer in the direction along the opening in FIG. 3 and the left side in FIG. 4, and the opposite side is the rear side. The parameter setting unit 23 manages each parameter assigned to each component connected to the input / output terminal block 21 as a memory address, and when the setting of any parameter is changed, the parameter setting unit 23 updates the setting value by not deleting the address of the changed parameter but leaving it as it is, and storing the changed parameter in another address in the memory. This makes the default value of the parameter unchanged, and the parameter in the memory whose setting has been changed can be accessed based on the changed address, and the change history of the parameter can be appropriately managed.

[0054] The motor drive board 22 is disposed in the space above the floor surface within the storage box 11, below the winding shaft 14 and the electric motor 17. The electric motor 17 is provided with a limit switch (not shown) constituted by a pulse generating rotary encoder or the like for detecting the rotational position, i.e., the open / closed position and open / closed state of the screen curtain 15. The motor drive board 22 receives a pulse signal output from this limit switch in accordance with the rotation of the electric motor 17, calculates the rotational position of the electric motor 17 and the position of the tip of the screen curtain 15 on the closed side at the opening, etc. based on the generation status of this pulse, and transmits the results to the input / output terminal block 21.

[0055] FIG. 5 is a diagram showing the connection relationship and schematic configuration of the input / output terminal block, motor drive board, and parameter setting unit that construct a control system for controlling the drive of the motor of the roller blind device of FIG. 3 and FIG. 4. The input / output terminal block 21 and the motor drive board 22, and the input / output terminal block 21 and the parameter setting unit 23 are connected by RS-485 communication cables 30, 31, respectively. RS-485 is a physical layer standard for a bus-type connection network system defined by the Electronic Industries Association (EIA), and is a communication method that allows multi-point connection. Therefore, since multiple devices can be connected on the same bus, in this embodiment, one input / output terminal block 21 manages both the motor drive board 22 and the parameter setting unit 23. In addition, it is possible to increase or decrease the number of devices and change the arrangement as appropriate.

[0056] 5, a DC voltage (power) is supplied between the input / output terminal block 21 and the motor drive board 22, between the input / output terminal block 21 and the parameter setting unit 23, and between the motor drive board 22 via power cables 32, 33. Also, in FIG. 5, the motor drive board 22 receives a signal indicating shutter position information from a limit switch 18 provided on the electric motor 17, and controls the electric motor 17 based on the signal.

[0057] A three-point push button 24 with a built-in area sensor serving as a non-contact type operator is connected to the input / output terminal block 21. Although FIG. 5 illustrates a case where one area sensor is provided, two or more area sensors may be provided. A sound generating device 35 is also connected to the input / output terminal block 21. In addition, the input / output terminal block 21 receives control signals indicating state changes output from various components such as pull switches, start sensors, signal lights, rotating lights, various sensors (such as photoelectric sensors for detecting obstacles), and remote control control circuits. Upon receiving a control signal indicating a state change output from these various components, the input / output terminal block 21 transmits a control signal to the motor drive board 22 and / or the parameter setting unit 23 via the communication cables 30 and 31 in order to execute a process corresponding to the control signal.

[0058] The motor drive board 22 controls the rotation of the electric motor 17 based on a control signal from the input / output terminal block 21 input via the communication cable 30. At this time, the motor drive board 22 converts the DC voltage supplied from the power cable 32 into an AC voltage to control the electric motor 17. The motor drive board 22 also receives a signal indicating shutter position information from the limit switch 18 provided on the electric motor 17, controls the electric motor 17 based on the signal, and transmits a signal indicating the shutter position information to the input / output terminal block 21 via the communication cable 30.

[0059] The sound generating device 35 may be built in the input / output terminal block 21, or may be disposed above the input / output terminal block 21 at a position where the operator can easily hear, for example, at the height of an average adult's head. The sound generating device 35 generates a buzzer sound or a sound other than the buzzer sound (voice or beep sound) to indicate the control state of the motor drive board 22, the setting state of the parameter setting unit 23, the operation state of the area sensor and the push button 24, etc. The sound generating device 35 has a voice recognition function and can also recognize the voice of the operator. The sound generating device 35 also generates a buzzer sound of a predetermined volume to indicate that the area sensor is in a finger detection state, or generates a sound other than the buzzer sound (voice or beep sound) to indicate that the area sensor is in a finger detection state.

[0060] FIG. 6 is a diagram showing a first embodiment of an input / output terminal block incorporating the parameter setting unit of FIG. 5. In FIG. 6, the same components as those in FIG. 2 are given the same reference numerals, and therefore the description thereof will be omitted. The input / output terminal block 21a of the first embodiment differs from that of FIG. 2 in that an area sensor 291 is provided above the lift (open) button 241 instead of the area sensor 25a of FIG. 2, which is a non-contact operation element, and an area sensor 292 is provided below the parameter setting unit 23 instead of the area sensor 25c. When any of the area sensors 291, 292 enters a detection state during the lift (open) operation or the lowering (closing) operation, or when the stop button 242 is operated, a stop operation is executed, so that the area sensor 25b is omitted in the first embodiment. The area sensor 25b may be provided near the stop button 242 as in FIG. 2.

[0061] In FIG. 6, the input / output terminal block 21 incorporates an operation mode changeover switch 271, operation status indicator lights (LEDs) 281-283, a parameter setting unit 23, a three-point push button 24 for opening and closing as a contact type operator, and area sensors 291, 292 as non-contact type operators. The input / output terminal block 21 is provided on the front side of the guide rail 13 at a position where the operator can easily operate it when entering the opening. The three-point push button 24 has an up (open) button 241, a stop (stop) button 242, and a down (close) button 243 as control switches corresponding to the opening and closing operations, and outputs control signals (up (open) signal, stop (stop) signal, down (close) signal) according to the operating state of each push button 24 to the microcomputer of the input / output terminal block 21 via a communication cable. Note that the three-point push button 24 may be replaced by a wireless remote control switch for operation.

[0062] The operation mode changeover switch 271 is a switch for switching the operation state of the roller blind device 10 between an automatic opening / closing mode in which the opening / closing operation is performed automatically according to the detection state of the sensor, and a manual opening / closing mode in which the operator manually operates the device. The operation state indicator light 281 is a power supply state indication LED that lights up when the power supply of the input / output terminal block 21a is turned on and goes out when the power supply is turned off. The operation state indicator light 282 is an abnormal state indication LED that lights up when an abnormality occurs in the roller blind device 10 and goes out when the device is normal. The operation state indicator light 283 is an opening / closing mode indication LED that lights up in the automatic opening / closing mode and goes out in the manual mode.

[0063] As shown in FIG. 6, the area sensors 291 and 292 have a detection area at approximately the center of a figure shaped like a hand. By applying the figure shaped like a hand, the operator can easily recognize the position of the area sensors 291 and 292. The area sensors 291 and 292 are configured as near-infrared distance-limited reflection area sensors similar to the area sensors 25a to 25c in FIG. 2, and detect a state in which a reflective object such as a finger 40 shown by a dotted line approaches the area sensors 291 and 292, and output the detection signal to the microcomputer of the input / output terminal block 21 via a communication cable. The detection range of the area sensors 291 and 292 is approximately the center of the figure shaped like a hand, and is an area (area) D, E about 5 to 15 cm in front of the sensor. The area sensors 291 and 292 detect the presence of a finger 40 when the finger 40 is located in the area (area) D, E shown by a dotted line.

[0064] The input / output terminal block 21a, which receives detection signals from the area sensors 291 and 292, which are non-contact type operators, executes detection signal processing based on the detection signals. This detection signal processing is processing for outputting signals in the same state as when the up (open) button 241 and the down (close) button 243 of the three-point push button 24 are pressed, based on the detection signals output from the non-contact type operators (area sensors 291 and 292) in response to the movement of the finger 40, which is an object. The separation distance between the areas D and E is preferably such that the finger 40 cannot be held over the areas D and E simultaneously even when spread out when the finger 40 is of a standard adult size, and is preferably such that the finger 40 pressing the three-point push button 24, which is a contact type operator, is not detected. The area sensor 291 is preferably disposed near the up (open) button 241, and the area sensor 292 is preferably disposed far away from the three-point push button 24. Specifically, as shown in FIG. 5, the area sensor 291 and the up (open) button 241 are positioned above approximately the vertical center of the input / output terminal block 21a, and the area sensor 292 is positioned near the bottom end of the input / output terminal block 21a, thereby effectively preventing erroneous detection.

[0065] The area sensor 291 is disposed above the approximate center of the input / output terminal block 21a in the vertical direction, near the upper side of the lift (open) button 241, and below the operation mode changeover switch 271. When an operator holds his / her finger near the lift (open) button 241 to open the roller blind device 10, the area sensor 291 detects the finger, and the roller blind device 10 executes the opening operation. That is, the area sensor 291 corresponds to a non-contact type opening button (open area sensor) corresponding to the lift (open) button 241. Also, when an operator tries to press the lift (open) button 241, the area sensor 291 may detect the finger before the pressing operation, and the roller blind device 10 may execute the opening operation. However, in this case, it cannot be said to be a false detection, and the opening operation intended by the operator has been executed.

[0066] On the other hand, the area sensor 292 is disposed on the lower side of the parameter setting unit 23 and at the bottom end of the input / output terminal block 21 as shown in FIG. 6. That is, the area sensor 292 is disposed at the position farthest from the push button 24 on the input / output terminal block 21. When an operator holds his / her finger near the area sensor 292 disposed on the bottom side of the input / output terminal block 21 to close the roller blind device 10, the area sensor 292 detects the finger 40, and the roller blind device 10 executes the closing operation. That is, the area sensor 292 corresponds to a non-contact type close button (close area sensor) corresponding to the down (close) button 243. The finger 40 includes not only a human finger but also a long and thin object similar to a human finger, such as a finger of a prosthetic hand, a pencil, or a pen.

[0067] According to the first embodiment, the area sensor 292 serving as a non-contact type close button is disposed at a position farthest from the push button 24 which is constantly operated when passing through the opening, that is, at a position where it does not detect the finger 40 pressing the three-point push button 24 which is a contact type operator, thereby preventing the area sensor 292 from erroneously detecting a finger when the operator presses the push button 24. Also, the area sensors 291, 292 are disposed at a distance of several times or more the size of a finger, thereby preventing the area sensors 291, 292 from detecting an object such as a finger by overlapping each other and thus preventing erroneous detection.

[0068] Fig. 7 is a diagram showing a second embodiment of an input / output terminal block incorporating the parameter setting unit of Fig. 5. In Fig. 7, the same components as those in Fig. 2 and Fig. 7 are given the same reference numerals, and their explanation will be omitted. The input / output terminal block 21 of the second embodiment is a modification of Fig. 2, and differs from that of Fig. 2 in that only the area sensor 25a of Fig. 2, which is a non-contact operator, is provided, and the area sensors 25b and 25c of Fig. 2 are omitted.

[0069] Fig. 8 is a diagram showing a third embodiment of an input / output terminal block incorporating the parameter setting unit of Fig. 5. In Fig. 8, the same components as those in Fig. 2 and Fig. 6 are given the same reference numerals, and their explanation will be omitted. The input / output terminal block 21c of the third embodiment is a modification of Fig. 6, and differs from that of Fig. 6 in that only the area sensor 291 of Fig. 6, which is a non-contact operator, is provided, and the area sensor 292 of Fig. 6 is omitted.

[0070] In the second embodiment of FIG. 7, only one area sensor 25a is provided, and in the third embodiment of FIG. 8, only one area sensor 291 is provided. This is the same as when a one-point switch is provided, so the opening and closing operations may be performed cyclically, such as open-stop-close-open-stop-close-. in response to the finger detection signal of the area sensors 25a and 291, as in the case where a one-point signal is input. In addition, the area sensors 25a and 291, which are non-contact type operators, may function as operators that perform the opening operation, and may automatically perform the closing operation when a predetermined time has elapsed after the stopping operation or the full opening operation. In this embodiment, when only one non-contact type operator (area sensor) is provided as in the second and third embodiments, the opening and closing control is not performed cyclically, but is performed according to the detection state of one non-contact type operator (area sensor). Details of the opening and closing control process performed according to the detection state of this one non-contact type operator (area sensor) will be described later.

[0071] Fig. 9 is a flow chart showing an example of processing executed by the input / output terminal block of the switching device according to this embodiment. Fig. 10 is a flow chart showing an example of processing executed by the motor drive board of the switching device according to this embodiment. Note that the processing executed by the parameter setting unit of the switching device according to this embodiment is described in Patent Document 2, so a description thereof will be omitted. Below, an example of processing executed by the switching device will be described using these flow charts.

[0072] An example of the process executed by the input / output terminal blocks 21a to 21c will be described with reference to FIG. In step S211, it is determined whether or not a signal indicating a state change has been input from each of the various connected components, and if the state has changed (yes), the process proceeds to the next step S212, and if not (no), the process jumps to step S213. Here, the signals indicating the state change correspond to, for example, a pressing operation signal from the three-point push button 24, a detection signal from the area sensors 291, 292, and 25a which are non-contact operation devices, an operation signal from a pull switch, an activation signal from a startup sensor, a detection signal from a photoelectric sensor for detecting obstacles, and the like.

[0073] In step S212, a control signal corresponding to a signal indicating a state change input from each of the various connected components is transmitted to the motor drive board 22 via the communication cable 30. For example, when a pressing operation signal is input from the three-point push button 24, an open / close control signal corresponding to each open / close push button 241-243 is transmitted to the motor drive board 22. In addition, detection signal processing is performed based on detection signals from the area sensors 291, 292, 25a, and an open / close control signal is transmitted to the motor drive board 22. Furthermore, when a detection signal is input from a photoelectric sensor for detecting an obstacle, a closing operation stop signal is transmitted to the motor drive board 22.

[0074] In step S213, it is determined whether or not a signal has been received via the communication cable 30. If a signal has been received (yes), the process proceeds to the next step S214, and if not (no), the process returns. In step S214, a process corresponding to the received signal is executed. For example, if the received signal is a process end signal from the motor drive board 22 or a signal indicating shutter position information of the limit switch 18 from the motor drive board 22, the process end of opening / closing the screen curtain 15 and the position of the screen curtain 15 at the time of the end are recognized based on the process end signal and the shutter position information, and are used for the subsequent process. Also, if the received signal is a signal related to parameter setting from the parameter setting unit 23, the parameters of the various processing modes of the input / output terminal block 21 are changed based on the signal related to the parameter setting, and a signal indicating the end of the setting change is sent to the parameter setting unit 23 via the communication cable 31.

[0075] An example of a process executed by the motor drive board 22 will be described with reference to FIG. In step S221, it is determined whether or not a signal has been received via the communication cable 30. If a signal has been received (yes), the process proceeds to the next step S222, and if not (no), the process returns. In step S222, a process corresponding to the received signal is executed. For example, if the received signal is a push operation signal of the three-point push button 24 from the input / output terminal block 21, an open / close control signal based on detection signals from the area sensors 291, 292, and 25a, or a closing operation stop signal based on a detection signal from a photoelectric sensor for detecting an obstacle, the process of opening / closing / stopping the screen curtain 15 is executed according to each signal.

[0076] In step S223, a signal indicating which operation (opening / closing / stopping) of the screen curtain 15 is being executed and its status, or a signal indicating the shutter position information of the limit switch 18, etc., is transmitted to the input / output terminal block 21 via the communication cable 30. In step S224, it is determined whether the received signal response processing in step S222 has been completed, that is, whether each opening / closing operation has been completed. If completed (yes), the process proceeds to the next step S225; if not (no), the process returns to step S222 until the operations are completed. In step S225, since the opening / closing and stopping operations have been completed, an end signal is sent to the input / output terminal block 21 via the communication cable 30.

[0077] Fig. 11 is a diagram showing an example of the first detection signal processing executed by the input / output terminal block of Fig. 6 based on the detection signal from the non-contact type operator in step S212 of Fig. 9. In this embodiment, the processing is executed using count registers Rd, Re and area flags Fd, Fe corresponding to the area sensors 291, 292 constituting the non-contact type operator provided on the input / output terminal block 21a of Fig. 6. The count registers Rd, Re store values ​​from a lower limit value "0" to an upper limit value "10", and are configured not to count values ​​below "0" or above "10".

[0078] In step S231, it is detected whether or not an object, such as a finger 40, is present in the detectable areas D, E of each area sensor 291, 292. If it is present (yes), the process proceeds to the next step S232; if it is not detected (no), the process jumps to step S233. In step S232, the count registers Rd and Re corresponding to the areas D and E in which the presence of the finger 40, which is an object, is detected are counted up (increment processing). In step S233, the count registers Rd and Re corresponding to the areas D and E in which the presence of the finger 40 as an object was not detected are counted down (decrement processing).

[0079] In step S234, it is determined whether any of the count registers Rd and Re has a count value of "10". If the count value is "10" (yes), the process proceeds to the next step S235. If the count value is "0" to "9" (no), the process jumps to step S236. In step S235, the area flags Fd, Fe corresponding to the count registers Rd, Re whose count values ​​are "10" are set to "1".

[0080] In step S236, it is determined whether any of the count registers Rd and Re has a count value of "0". If the count value is "0" (yes), the process proceeds to the next step S237, and if the count value is "1" to "10" (no), the process jumps to step S238. In step S237, the area flags Fd, Fe corresponding to the count registers Rd, Re whose count values ​​are "0" are reset to "0". In step S238, the determination is made until 1 [msec] has elapsed since the determination in step S231. That is, by this determination, a sampling process is performed every 1 [msec] to determine whether or not finger 40, which is an object, is present in areas D and E.

[0081] In step S239, signal output processing is executed according to the "0" or "1" state of the area flags Fd, Fe rewritten by the processing in steps S235 and S237. If the area flags Fd, Fe are both in the "0" state or in the "1" state while the screen curtain 15 is stopped, signal output processing is not executed. If the area flag Fd is "1" and the area flag Fe is in the "0" state while the screen curtain 15 is stopped, a rise signal is output to the motor drive board 22. If the area flag Fd is "0" and the area flag Fe is in the "1" state while the screen curtain 15 is stopped, a fall signal is output to the motor drive board 22.

[0082] On the other hand, when the area flags Fd and Fe are both in the "0" state while the screen curtain 15 is in operation (lowering or rising), no signal output process is performed. When the area flag Fd is "1" and the area flag Fe is in the "0" state while the screen curtain 15 is in operation, when the area flag Fd is in the "0" state and the area flag Fe is in the "1" state, or when the area flags Fd and Fe are both in the "1" state, a stop signal is output to the motor drive board 22. The rise signal, stop signal, and fall signal are output to the motor drive board 22 as a one-shot signal of approximately 100 [msec].

[0083] 11, the case where the area sensors 291, 292 output the up signal and down signal at the same time that they detect a finger has been described, but the detection time of the area sensor 291 may be shorter than the detection time of the area sensor 292. In this case, the upper limit value of the count register Rd may be set to "10", the upper limit value of the count register Re may be set to "30", and "1" may be stored in the area flags Fd, Fe when the upper limit values ​​are reached. Note that the sampling process time and the lower and upper limit values ​​of the count registers Rd, Re are merely examples, and may be greater or smaller than these values.

[0084] Fig. 12 is a diagram showing an example of the second detection signal processing executed by the input / output terminal block of Fig. 6 based on the detection signal from the non-contact type operator in step S212 of Fig. 9. In this first detection signal processing, the time of the detection state of one non-contact type operator (area sensor 25a or 291) provided on the input / output terminal block 21b of Fig. 7 or the input / output terminal block 21c of Fig. 8 is timed by a timer T, and a control signal for an opening operation or a closing operation is transmitted according to the time measured by the timer T. The second detection signal processing is executed at a predetermined interrupt timing (every 1 to 100 [msec]).

[0085] In step S241, it is detected whether or not an object, such as a finger 40, is present in the detectable areas A and D of the area sensors 25a and 291. If the presence is detected (yes), the process proceeds to the next step S242; if the presence is not detected (no), the process proceeds to step S243.

[0086] In step S242, the power status display LED of the operation status indicator 281 is made to flash in order to make the operator recognize that the area sensors 25a, 291, which are non-contact type operators, are in a detection state. Similarly, in order to make the operator recognize that the area sensors 25a, 291 are in a detection state, a buzzer sound of a predetermined volume is sounded from the sound generating device 35, and a sound other than a buzzer sound (voice, beep sound, etc.) is also sounded. Note that both the LED flashing and the buzzer sound or sound may be executed, or only one of them may be executed.

[0087] In step S243, it is determined based on the value of timer T whether the state in which the area sensors 25a, 291 have detected the finger 40 has continued for three seconds or more. If three seconds have not elapsed (no), the process proceeds to step S244. If three seconds or more have elapsed (yes), the process proceeds to step S245. In step S244, since the timer T is not 3 seconds or more, the timer T is counted up (increment processing) and the process returns.

[0088] In step S245, since the detection state in the previous step S243 has continued for 3 seconds or more, a one-shot down signal is output to the motor drive board 22 to lower (close) the screen curtain 15, and the process proceeds to step S248. The motor drive board 22 that has received the down signal executes the down operation (closing operation) of the screen curtain 15. In step S246, it is determined based on the value of timer T whether the state in which the area sensors 25a, 291 have detected the finger 40 has continued for one second. If it has continued for one second (yes), the process proceeds to the next step S247. If it has not continued for one second (no), the process proceeds to step S248.

[0089] In step S247, since the detection state in the previous step S246, i.e., the value of the timer T, is equal to or greater than 1 second and less than 3 seconds, a one-shot up signal is output to the motor drive board 22 to raise (open) the screen curtain 15, and the process proceeds to step S248. The motor drive board 22 that has received the up signal performs the up operation (open operation) of the screen curtain 15.

[0090] In step S248, since the closing operation signal was sent in step S245, the opening operation signal was sent in step S247, or it was determined in step S246 that the detection state did not continue for one second, the timer T is reset to "0", the power status display LED that was blinking in step S242 is returned to the original lighting state, and further, the buzzer sound and sound are stopped. By changing the power status display LED from the blinking state to the lighting state and by stopping the sound, the operator can recognize that the finger has been effectively detected and the process corresponding to the finger has been executed. That is, when the finger is effectively detected, the power status display LED blinks and the buzzer sounds and sounds are generated, so the operator can easily understand the current detection state and can also understand how close the finger needs to be to the area sensor 25a, 291 to be detected. The power status display LED is turned off when the input power of the input / output terminal block is off.

[0091] 12, when area sensor 25a, 291, which is a non-contact type operator, detects an object such as a finger for one second or more and becomes undetected before three seconds have elapsed, it performs a raising operation of screen curtain 15, and when the detection state continues for three seconds or more, it performs a lowering operation of screen curtain 15. In the second detection signal processing, the duration of the detection time for performing the raising operation is set to a range of one to three seconds, and the duration of the detection time for performing the lowering operation is extended to three seconds or more, so that even if a user unintentionally places a finger over area sensor 25a, 291, screen curtain 15 will not start the lowering operation unless the finger is held over for three seconds or more, thereby preventing the occurrence of an unintentional lowering operation.

[0092] In the second detection signal processing of FIG. 12, the raising operation is not executed unless the detection state continues for one second or more, but if the screen curtain 15 is in a fully closed state, the raising operation is initiated when the area sensor 25a, 291 detects fingers, and if the screen curtain 15 is in a fully open state, the lowering operation is initiated when the area sensor 25a, 291 detects fingers continuously for three seconds or more, and the processing of FIG. 12 may be executed if the screen curtain 15 is in an intermediate stop state such as a half-open or half-closed state.

[0093] Fig. 13 is a diagram showing an example of the third detection signal processing executed by the input / output terminal block of Fig. 6 based on the detection signal from the non-contact type operator in step S212 of Fig. 9. In this third detection signal processing, the time of the detection state of one non-contact type operator (area sensor 25a or 291) provided on the input / output terminal block 21b or the input / output terminal block 21c of Fig. 7 is measured by a timer T, and if the finger moves upward (opening direction) after a predetermined time has elapsed, a control signal for an opening operation is transmitted, and if the finger moves downward (closing direction), a control signal for a closing operation is transmitted. The third detection signal processing is executed at a predetermined interrupt timing (every 1 to 100 [msec]).

[0094] In step S251, it is detected whether or not an object, such as a finger 40, is present in the detectable areas A and D of the area sensors 25a and 291. If the presence is detected (yes), the process proceeds to the next step S252; if the presence is not detected (no), the process proceeds to step S261.

[0095] In step S252, it is determined based on the value of timer T whether the state in which the area sensors 25a, 291 have detected the finger 40 has continued for one second or more. If one second has not passed (no), the process proceeds to step S253. If one second or more has passed (yes), the process proceeds to step S254. In step S253, the power state display LED of the operation state indicator lamp 281 is caused to flash at high speed (long cycle, e.g., 2 to 4 Hz) to allow the operator to recognize that the area sensors 25a, 291, which are non-contact type operators, are in a detection state. Similarly, to allow the operator to recognize that the area sensors are in a detection state, the sound generating device 35 emits a buzzer sound of a predetermined volume at high speed (short cycle, e.g., 2 to 4 Hz), and generates a sound other than the buzzer sound (voice, beep, etc.).

[0096] In step S254, the power state display LED of the operation state indicator lamp 281 is made to blink at a slow timing (long cycle, for example, 0.3 to 1.5 [Hz]) to make the operator recognize that the detection state of the area sensors 25a, 291, which are non-contact type operators, has continued for one second or more. Similarly, to make the operator recognize that one second or more has passed, a buzzer sound of a predetermined volume is sounded from the sound device 35 at a long timing (long cycle, for example, 0.3 to 1.5 [Hz]) and a sound other than the buzzer sound (voice, beep sound, etc.) is produced. Note that in steps S253 and 254, both the LED blinking and the buzzer sounding or sounding may be executed, or only one of them may be executed.

[0097] In step S255, it is determined whether the area sensors 25a, 291 have detected an upward movement of a finger. If the upward movement is detected (yes), the process proceeds to step S257. If the movement is not detected (no), the process proceeds to step S256. In step S256, it is determined whether the area sensors 25a, 291 have detected a downward movement of a finger. If a downward movement has been detected (yes), the process proceeds to step S257. If no movement has been detected (no), the process proceeds to step S258. That is, in steps S255 and 256, it is determined whether the finger is moving upward or downward. When it is detected that the finger is moving in a range of 45 degrees or less from approximately the center of the area sensor 25a or 291 toward the upper side in the vertical direction, it is determined that the finger is moving upward. When it is detected that the finger is moving in a range of 45 degrees or less from the center of the area sensor 25a or 291 toward the lower side in the vertical direction, it is determined that the finger is moving downward. This 45 degree angle is an example, and it may be more or less than this.

[0098] In step S257, since an upward movement of a finger was detected in the previous step S255, a one-shot up signal is output to the motor drive board 22 to raise (open) the screen curtain 15, and the process proceeds to step S261. The motor drive board 22 that has received the up signal performs the up movement (opening) of the screen curtain 15.

[0099] In step S258, since the downward movement of the finger was detected in the previous step S256, a one-shot down signal is output to the motor drive board 22 to lower (close) the screen curtain 15, and the process proceeds to step S261. The motor drive board 22 that has received the down signal executes the down operation (closing operation) of the screen curtain 15.

[0100] In step S259, it is determined based on the value of timer T whether the state in which the area sensors 25a, 291 have detected the finger 40 has continued for three seconds or more. If three seconds have not elapsed (no), the process proceeds to step S260. If three seconds or more have elapsed (yes), the process proceeds to step S261. In step S260, the timer T is counted up (increment processing) and the process returns.

[0101] In step S261, since an opening signal was sent in step S257, a closing signal was sent in step S258, or it was determined in step S259 that the detection state was 3 seconds or longer, the timer T is reset to "0", the power status display LED that was blinking in steps S253 and S254 is turned on, and further, the buzzer sound and sound emission are stopped. By changing the power status display LED from a blinking state to a lit state and by stopping the sound emission, the operator can recognize that the finger has been effectively detected and the corresponding process has been executed.

[0102] In the third detection signal processing of Fig. 13, when the area sensor 25a, 291, which is a non-contact type operator, detects an object such as a finger for one second or more and detects that the object has moved upward, the screen curtain 15 is raised, or when the area sensor 25a, 291 detects that the object has moved downward, the screen curtain 15 is lowered. This prevents unintended raising or lowering of the screen curtain 15, since the screen curtain 15 does not start raising or lowering even if the user unintentionally places a finger over the area sensor 25a, 291, unless the user intentionally moves the finger upward or downward. In the third detection signal processing of Fig. 13, if the area sensor 25a, 291 detects an object such as a finger while the screen curtain 15 is raising or lowering, the raising or lowering may be stopped.

[0103] In the above embodiment, the input / output terminal block 21 with the built-in parameter setting unit 23 is provided on the front surface of the guide rail 12, but the input / output terminal block 21 may be provided on the guide rail 12 and / or 13.

In this configuration, the communication cable 30 can be prevented from being exposed to the outside. In this case, the position of the input / output terminal block 21 is preferably a position where it is easy for an adult to operate, and although it depends on the height of the guide rail 12 and / or 13, it is preferably near the center position in the height direction avoiding the upper and lower parts of the guide rail 12 and / or 13 in consideration of a normal building, etc.

[0104] In the above embodiment, an example of the input / output terminal block 21 having the parameter setting unit 23 built in has been described, but the parameter setting unit 23 and the input / output terminal block 21 may also be provided at separate positions on the guide rails 12 and / or 13.

When the opening / closing member is of an up-and-down lift type, configured so that it closes when raised and opens when lowered, the opening button 241 and the closing button 243 are arranged with the closing button 243 on the upper side and the opening button 241 on the lower side. Furthermore, when the opening / closing member is pulled out laterally or horizontally, the close button 243 is provided to be positioned closer to the closing direction than the open button 241 in accordance with the direction in which the opening / closing member is pulled out, in other words, the closing direction.

[0105] In the above embodiment, a case where an obstacle sensor is not provided has been described, but an obstacle sensor may be provided near the weight bar and / or near the opening.
