  Some electric devices such as air conditioners control operation by a control unit such as a remote controller. A common control unit may be used in a plurality of electric devices having slightly different configurations such as a high-end machine and a low-end machine. A control unit used in a plurality of electrical devices having different configurations needs to be set according to the configuration of the electrical device. 2. Description of the Related Art Conventionally, a control unit that includes a switch for selecting a configuration of an electric device and performs setting according to the configuration selected by a user operating the switch is used. For example, a dip switch is used as the switch.

  In a control unit used in a plurality of electrical devices having different configurations, there is a problem that the configuration of the selected electrical device may be different from the actual configuration. When a configuration different from the actual configuration is selected by the switch, an incorrect setting is performed, and the control unit cannot normally control the electrical device. By the way, as a light shielding device that shields external light with a plurality of slats, there is an electric light shielding device in which movement of the slats is motorized, and the electric light shielding device has the same problem. That is, there are a plurality of types of light shielding devices with different numbers or sizes of slats, and a common control unit is used in the plurality of types of light shielding devices, and the selection of the configuration received by the control unit is wrong. There is a risk of being. Therefore, it is necessary to determine whether the selection of the configuration of the light shielding device received by the control unit is correct. Patent Document 1 describes that in an air conditioner, a control unit executes a special mode for determining correctness of setting.

Japanese Patent No. 2504247

  When the technique described in Patent Document 1 is applied to a light shielding device, the light shielding device needs to execute a special mode for determining whether the setting is correct. There is a problem that it takes time and effort for the user to confirm whether or not. Further, even if the selection of the configuration received by the control unit is incorrect, there is a problem that the user does not notice the error unless the light shielding device executes a special mode.

  The present invention has been made in view of such circumstances, and the object of the present invention is to accept it by the control unit by performing an operation according to the correctness of the selection of the configuration in performing a normal operation. An object of the present invention is to provide a light-shielding device that allows a person to easily check whether the configuration of the light-shielding device is correct or incorrect.

  The light-shielding device according to the present invention includes a plurality of units including a light-shielding unit having a light-shielding member and a drive unit that causes the light-shielding unit to perform a plurality of types of operations including an operation of moving the light-shielding member in a predetermined direction. A control unit for controlling the drive unit, wherein the control unit controls the drive unit according to the selection received by the reception unit and a reception unit that receives a selection of models of the plurality of units. In the light-shielding device having the control method setting unit, the control unit determines whether the selection received by the receiving unit matches the actual model of the plurality of units, and When the determination unit determines that the selection does not match the actual model of the plurality of units, when the drive unit is controlled, the operation to be performed by the light shielding unit on the drive unit is stopped halfway. Characterized in that it comprises a stop means.

  In the present invention, the light-shielding device that controls the drive unit that operates the light-shielding unit having the light-shielding member by the control unit accepts selection of models of a plurality of units included in the light-shielding device, and the received selection matches the actual model. If not, the operation of the light shielding unit is stopped halfway. As a result, it is found that the unit type is wrongly selected when the light shielding device performs a normal operation.

  In the light-shielding device according to the present invention, the control unit associates each of the plurality of units with any one of a plurality of operations that the driving unit causes the light-shielding unit to perform. When the drive unit is controlled to cause the light shielding unit to perform an operation associated with a unit whose selection received by the receiving unit does not match an actual model, the drive unit It is characterized by having a means for stopping the operation to be performed by the light shielding part on the way.

  In the present invention, the light-shielding device stops the operation of the light-shielding unit halfway when performing an operation according to a unit whose received selection does not match the actual selection. This makes it easy to determine which unit model selection is not constant.

  In the light-shielding device according to the present invention, the accepting unit has a plurality of switches for accepting selection of models for each of the plurality of units, and each switch is a plurality of models predetermined as models of the corresponding units. The switch is configured to accept one of the selections, and once the switch selects the model, the switch accepts the selection of any one of the models, so that the model of the unit corresponding to the switch And a means for accepting a change in selection.

  In the present invention, the light-shielding device has a switch that accepts any one of a plurality of models determined in advance as a unit model for each of the plurality of units. When changing the selection of each unit, the shading device once again accepts any one of the selections after deselecting all of them with the switch corresponding to each unit. Since the setting is reset once and then set again, it is possible to prevent the malfunction of the light shielding device due to the remaining setting before the change.

  In the light-shielding device according to the present invention, the control unit includes a unit that determines an actual model of the plurality of units, and the stop unit includes the driving unit, and the state of the light-shielding unit is actually the plurality of units. The operation performed by the light shielding unit is stopped after the operation of the light shielding unit is performed until a state corresponding to the model of the unit is obtained, and then the operation performed by the light shielding unit is stopped.

  In the present invention, the light shielding device determines the actual model of the unit, operates the light shielding unit until it reaches a state corresponding to the model of the actual unit, and then stops the operation of the light shielding unit. Thereby, the actual configuration of the light shielding device can be easily found.

  In the present invention, the light-shielding device does not need to perform special processing to confirm whether or not the received configuration selection is correct, and the user or the operator who performs the setting is in normal operation. In addition, it is possible to easily know that the selection of the configuration received by the light shielding device is wrong by confirming that the light shielding device stops halfway. On the contrary, the present invention is excellent in that the user or the operator can easily know that the selection of the configuration received by the light shielding device is correct by confirming that the light shielding device operates without stopping. Has an effect.

Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof.
FIG. 1 is a block diagram showing the configuration of the light shielding device of the present invention. The light shielding device of the present invention includes a slat part (light shielding part) 3 composed of a plurality of slats, a drive part 2 that drives the slats of the slat part 3 by a motor, a control part 1 that controls the drive part 2, and a drive part 2. And a power supply unit 4 for supplying power to the control unit 1. The power supply unit 4 is connected to the drive unit 2 and the control unit 1 through a power supply line. The control unit 1 is connected to the drive unit 2 through a control signal line for transmitting a control signal. The control unit 1 is connected to the drive unit 2, the slat unit 3, and the power supply unit 4 through data lines for receiving data from each unit. The drive unit 2, the slat unit 3, and the power supply unit 4 correspond to units in the present invention, respectively. As each unit, a plurality of models having different configurations can be used, and any one model is used. The configuration of the light shielding device is determined by combining a plurality of units using any one of the models.

  FIG. 2 is a schematic diagram showing an example of the appearance of the drive unit 2 and the slat unit 3. The slat part 3 is configured by arranging a large number of slats 31 formed in a rectangular flat plate shape in parallel in a direction intersecting the long side direction. The slat 31 corresponds to the light shielding member in the present invention. The plurality of parallel slats 31 are connected by a wire. The drive unit 2 has a rectangular parallelepiped appearance and includes a motor inside. The drive unit 2 causes the slat part 3 to perform an operation of raising the plurality of slats 31 and an operation of lowering the plurality of slats 31 by performing winding and feeding of the wire connecting the plurality of slats 31 with a motor. . When the plurality of slats 31 are raised, the interval between the plurality of slats 31 is reduced and the entire slat portion 3 is folded. When the plurality of slats 31 are lowered, the interval between the plurality of slats 31 is widened and the entire slat portion 3 is developed. Further, the drive unit 2 operates to open the slats 3 by changing the inclination of the slats 31 about the longitudinal axis in the direction in which the gap between the slats 31 is widened in the deployed slats 3. To do. In addition, the drive unit 2 moves the slats 3 in the closed state by changing the inclination of each slat 31 around the longitudinal axis in the direction in which the gap between the slats 31 is closed in the deployed slats 3. To do. When the slat part 3 is opened, the light shielding device introduces external light, and when the slat part 3 is closed, the light shielding device blocks external light.

  FIG. 3 is a block diagram illustrating an internal configuration of the control unit 1. The control unit 1 includes a control processing unit 11 that executes information processing for controlling the driving unit 2. The control processing unit 11 is a microcomputer including a CPU or DSP that performs computation, a memory that stores temporary data associated with information processing, and a non-volatile memory that stores various programs and data necessary for information processing. It is configured. A connection interface 12 is connected to the control processing unit 11, and the connection interface 12 is connected to the drive unit 2, the slat unit 3, and the power supply unit 4. The control processing unit 11 transmits and receives signals to and from the drive unit 2, the slat unit 3, and the power supply unit 4 via the connection interface 12. The control processing unit 11 includes an input unit 14 for inputting various instructions for moving the slat unit 3 by a user's operation, and a display unit 13 for displaying information necessary for inputting the instructions. ing. The display unit 13 and the input unit 14 may be integrally configured like a touch panel.

  The control processing unit 11 is connected to selection switches 15 to 18 for receiving selection of the model of each unit included in the light shielding device. The selection switches 15 to 18 are operated by a user or an operator who performs initial setting of the light shielding device at the time of manufacture. The selection switches 15 to 18 and the control processing unit 11 correspond to reception means in the present invention. Each of the selection switches 15 to 18 is associated with each of a plurality of units included in the light shielding device. When the selection switches 15 to 18 accept the selection of the model of each unit, the light shielding device accepts the selection of the entire configuration.

  FIG. 4 is a schematic diagram illustrating an example of the appearance of the selection switch 15. The selection switch 15 is a dip switch composed of a plurality of slide switches. Each slide switch is associated with a specific model of a unit corresponding to the selection switch 15, and is numbered. When any one of the slide switches is turned on, the model corresponding to the slide switch that is turned on is selected as the model of the unit corresponding to the selection switch 15. FIG. 4 shows an example in which the selection switch 15 is composed of four slide switches, the slide switch numbered 3 is turned on, and the other slide switches are turned off. The example shown in FIG. 4 shows that there are four types of units corresponding to the selection switch 15 and the model corresponding to the number 3 is selected. The configuration of the selection switches 16 to 18 is the same as that of the selection switch 15. The selection switches 15 to 18 may be configured by switches other than slide switches such as rotary switches or push switches.

  FIG. 5 is a conceptual diagram illustrating an example of a correspondence relationship between the selection switches 15 to 18 and the blind units. The selection switch 15 is associated with the power supply unit 4 as a unit. There are four types of models of the power supply unit 4: DC power supply type 1, DC power supply type 2 with different outputs, AC power supply type 1, and AC power supply type 2 with different outputs. Each of the slide switches numbered 1 to 4 is associated with each model. The selection switch 15 is associated with the slat 31 as a unit. There are four types of slats 31 including types 1 to 4 of slats 31 having different widths, lengths, or materials. Each of the slide switches numbered 1 to 4 is associated with each model. The selection switch 17 is associated with the drive unit 2 as a unit. There are four types of models of the drive unit 2 including motors of types 1 to 4 having different sizes, output torques, or drive methods as motors. Each of the slide switches numbered 1 to 4 is associated with each model. The selection switch 18 is associated with the slat part 3 as a unit. The model of the slat portion 3 has four possibilities of one-stage type, two-stage type, three-stage type, and four-stage type in which the number of rows of slats 31 arranged in parallel is different. Each of the slide switches numbered 1 to 4 is associated with each model. When there are more than four models that can be selected, each selection switch includes more slide switches.

  When one of the multiple slide switches included in each selection switch is turned on and the other slide switch is turned off, the model corresponding to the slide switch that is turned on is selected. The For example, the AC power supply type 1 is selected as the model of the power supply unit 4 by turning on the slide switch of number 3 among the four slide switches constituting the selection switch 15. By selecting the model of each unit using each of the selection switches 15 to 18, the configuration of the light shielding device including each unit is selected.

  The control processing unit 11 stores setting information necessary for controlling each unit of the light shielding device in advance. The content of the setting information is, for example, the value of the drive current supplied to the motor in the drive unit 2. When the slat 31 is large and heavy, it is necessary to increase the output of the motor that moves the slat 31, so that the value of the drive current increases. When the slat 31 is small and light, the output of the motor that moves the slat 31 is small. Therefore, the value of the drive current is small. Thus, the appropriate control method for controlling the drive unit 2 differs depending on the type of unit. The control processing unit 11 stores setting information in which an appropriate control method corresponding to each model of each unit is recorded in association with each slide switch of each selection switch. In addition, the control processing unit 11 reads setting information associated with the slide switch that has been turned on, and executes processing for controlling each unit of the light shielding device according to the read setting information.

  The selection is temporarily reset by turning off all of the plurality of slide switches included in each selection switch, and the selection is changed at each selection switch by turning any one of the slide switches on again. In this way, the selection of the model of each unit by the selection switches 15 to 18 is changed. For example, all of the four slide switches constituting the selection switch 15 are once turned off and the slide switch number 2 is turned on again, whereby the DC power supply type 2 is selected again as the model of the power supply unit 4. When all the slide switches included in each selection switch are turned off, the control processing unit 11 initializes settings related to the selection switches, and reads setting information associated with the slide switches that are turned on again. . Since the setting is initialized once and then set again, it is possible to prevent malfunction due to the remaining setting before the change. In addition, since the user or operator performs an operation of turning off all the slide switches constituting each selection switch and turning on one slide switch again, the user or the operator selects the model of each unit. Will be confirmed. Therefore, the possibility that the same error occurs again is reduced.

  Furthermore, as shown in FIG. 5, each of the selection switches 15 to 18 is associated with a predetermined operation among a plurality of types of operations that the drive unit 2 can cause the slat unit 3 to perform. In the example illustrated in FIG. 5, the selection switch 15 is associated with an operation for raising the plurality of slats 31. An operation for lowering the plurality of slats 31 is associated with the selection switch 16. The selection switch 17 is associated with an operation for opening the slat portion 3. The selection switch 18 is associated with an operation for closing the slat portion 3. The control processing unit 11 stores information indicating each operation in association with each selection switch. Further, when the selection of the model of the unit accepted by each selection switch does not match the actual model, the control processing unit 11 is in the middle of causing the drive unit 2 to execute the operation associated with each selection switch. Control to stop.

  FIG. 6 is a flowchart showing a procedure of processing in which the control processing unit 11 controls the driving unit 2. The control processing unit 11 waits for input of an operation instruction for instructing an operation to be executed by the slat unit 3 to the input unit 14 when a user or a setting operator operates the input unit 14 ( S1). If no operation instruction is input (S1: NO), the control processing unit 11 continues to wait for an operation instruction input. When an operation instruction is input (S1: YES), the control processing unit 11 determines whether the instructed operation is an operation associated with any of the selection switches 15 to 18 (S2). . When the instructed operation is an operation associated with one of the selection switches 15 to 18 (S2: YES), the model of the unit selected by the selection switch associated with the instructed operation is the actual model. It is determined whether or not (S3).

  In step S3, the connection interface 12 receives the data transmitted from the unit via the data line, and the control processing unit 11 determines that the model of the unit selected by the selection switch is based on the received data. It is determined whether or not it matches the configuration. For example, the data line between the power supply unit 4 and the control unit 1 includes a first data line and a second data line, and the power supply unit 4 is connected to an actual model via the first data line and the second data line. A high or low signal determined according to the transmission is transmitted. When the model of the power supply unit 4 is the DC power supply type 1 corresponding to the number 1 slide switch of the selection switch 15, the power supply unit 4 transmits a low signal on both the first data line and the second data line. To do. When the model of the power supply unit 4 is the DC power supply type 2, the power supply unit 4 transmits a low signal through the first data line and transmits a high signal through the second data line. When the model of the power supply unit 4 is the AC power supply type 1, the power supply unit 4 transmits a high signal through the first data line and transmits a low signal through the second data line. When the model of the power supply unit 4 is the AC power supply type 2, the power supply unit 4 transmits a high signal on both the first data line and the second data line. Thus, the power supply unit 4 transmits data indicating its model to the control unit 1 through the data line. The data lines may be configured to transmit 2-bit data collectively instead of transmitting signals to the first data line and the second data line, respectively. Similarly, the drive unit 2 and the slat unit 3 also transmit data indicating their models to the control unit 1 through a data line. The connection interface 12 receives data from each unit, and the control processing unit 11 compares the model of the unit indicated by the received data with the model of the unit selected by the selection switch, and the selected model is the actual model. Judge whether it matches the model.

  Each unit may be configured in advance so as to transmit data fixed according to the model, and is configured to detect its model and transmit data indicating the detected model. Also good. Further, the timing at which the control unit 1 receives data according to the model of each unit is not limited to the timing of step S2, and the control unit 1 receives data from each unit at other timing such as when the light shielding device is activated. May be received. In addition, the control processing unit 11 uses other methods such that each unit is provided with a memory that stores data indicating the actual model, and information indicating the actual model is read from the unit memory in step S3 to make a determination. You may perform the process of step S3.

  In step S2, when the instructed operation is not associated with any of the selection switches 15 to 18 (S2: NO), the control processing unit 11 instructs the drive unit 2 to instruct the instructed operation to the slat unit 3. The operation is executed according to the operation instruction (S6). In step S3, when the model of the unit selected by the selection switch matches the actual model (S3: YES), the control processing unit 11 is similarly instructed to the drive unit 2. The operation is executed by the slat part 3 in accordance with the operation instruction (S6).

  In step S3, if the model of the unit selected by the selection switch does not match the actual model (S3: NO), the control processing unit 11 selects the actual model of the unit selected by the selection switch. Determine (S4). For example, in step S4, the control processing unit 11 determines the actual model according to the data indicating the actual model received from each unit. Next, the control processing unit 11 causes the slat unit 3 to execute the operation instructed by the drive unit 2 until the state of the slat unit 3 becomes a predetermined state corresponding to the determined actual model, and then performs the operation. Stop (S5). After step S5 or step S6 is completed, the control processing unit 11 ends the process of controlling the drive unit 2. The control processing unit 11 repeats the process from step S1.

  A processing example in step S5 will be described. Although the slide switch number 1 of the selection switch 15 is in the on state, the actual power supply unit 4 is assumed to be the AC power supply type 1. In this case, in the operation of raising the plurality of slats 31, the control processing unit 11 causes the drive unit 2 to lower the plurality of slats 31 to the lowest limit, and then raises the plurality of slats 31. After raising to a position corresponding to the slide switch, the plurality of slats 31 are stopped. For example, the plurality of slats 31 stop at a position at a height of three quarters from the bottom within the ascending range excluding the vicinity of the lower limit and the vicinity of the upper limit. The user or the operator can know that the selection of the model of the power supply unit 4 using the selection switch 15 is wrong by confirming that the operation of raising the plurality of slats 31 is stopped halfway. . In addition, the user or operator confirms that it is a correct choice to turn on the slide switch of number 3 of the selection switch 15 by stopping the plurality of slats 31 at positions corresponding to the slide switch of number 3. I can know. Similarly, when it is a correct selection to turn on the slide switch number 1, 2, or 4 of the selection switch 15 and the other slide switches are in the on state, the plurality of slats 31 have their respective slides. Stops after ascending to the position corresponding to the switch. For example, in each case, the plurality of slats 31 have a height of one quarter, two quarters, or four quarters from the bottom within the ascending range excluding the vicinity of the lower limit and the upper limit. Stop in position.

  It is assumed that the actual slat 31 is a type 4 slat although the number 2 slide switch of the selection switch 16 is in the ON state. In this case, in the operation of lowering the plurality of slats 31, the control processing unit 11 causes the drive unit 2 to once raise the plurality of slats 31 to the upper limit, and then lowers the plurality of slats 31. The plurality of slats 31 are stopped after being lowered to a position corresponding to the slide switch. For example, the plurality of slats 31 stop at a position of a quarter height from the bottom within the descending range excluding the vicinity of the lower limit and the vicinity of the upper limit. The user or the operator can know that the selection of the model of the slat portion 3 using the selection switch 16 is incorrect by confirming that the operation of lowering the plurality of slats 31 is stopped halfway. . In addition, the user or the operator confirms that the plurality of slats 31 are stopped at the positions corresponding to the number 4 slide switch, so that the number 4 slide switch of the selection switch 16 is turned on. I can know. Similarly, when it is a correct selection to turn on the slide switch number 1, 2, or 3 of the selection switch 16 and the other slide switches are in the on state, the plurality of slats 31 have their respective slides. Stops after descending to the position corresponding to the switch.

  Although the number 1 slide switch of the selection switch 17 is in the ON state, the actual drive unit 2 is assumed to be a model equipped with a type 3 motor. In this case, the control processing unit 11 performs an operation of opening the plurality of slats 31 after causing the driving unit 2 to completely close the plurality of slats 31 once in the operation of opening the plurality of slats 31. The plurality of slats 31 are stopped after being opened to an angle corresponding to the number 3 slide switch. For example, the plurality of slats 31 are stopped in a state where they are opened by an angle of three quarters within an angular range excluding the fully closed state and the vicinity of the fully open state. The user or the operator can know that the selection of the motor model using the selection switch 17 is wrong by confirming that the operation of opening the plurality of slats 31 is stopped halfway. . In addition, the user or operator confirms that it is a correct choice to turn on the slide switch of number 3 of the selection switch 17 by stopping the plurality of slats 31 at the position corresponding to the slide switch of number 3. I can know. Similarly, when it is a correct selection to turn on the slide switch number 1, 2, or 4 of the selection switch 17 and the other slide switches are in the on state, the plurality of slats 31 have their respective slides. Stop after opening to the angle corresponding to the switch. For example, in each case, the plurality of slats 31 are opened by a quarter, two-quarter or four-quarter angle within an angular range excluding the vicinity of the fully closed state and the vicinity of the fully open state. Stop in state.

  Although the slide switch number 2 of the selection switch 18 is in the ON state, the actual slat portion 3 is assumed to be a four-stage type. In this case, the control processing unit 11 performs the operation of closing the plurality of slats 31 after causing the driving unit 2 to completely open the plurality of slats 31 once in the operation of closing the plurality of slats 31. The plurality of slats 31 are stopped after being executed and closed to an angle corresponding to the slide switch number 4. For example, the plurality of slats 31 are stopped in a state where the slats 31 are closed to the position of the quarter angle within an angular range excluding the vicinity of the fully closed state and the fully open state. The user or the operator knows that the selection of the model of the slat part 3 using the selection switch 18 is incorrect by confirming that the operation of closing the plurality of slats 31 is stopped halfway. Can do. In addition, the user or operator confirms that it is a correct choice to turn on the slide switch of number 4 of the selection switch 18 by stopping the plurality of slats 31 at the position corresponding to the slide switch of number 4. I can know. Similarly, when it is a correct selection to turn on the slide switch number 1, 2, or 3 of the selection switch 18 and the other slide switches are in the on state, the plurality of slats 31 have their respective slides. Stops after closing to the angle corresponding to the switch.

  As described above in detail, the light-shielding device of the present invention performs the operation according to the unit whose selection does not match the actual when the selection of the model of each unit received by the selection switches 15 to 18 does not match the actual. Stop halfway through. Since the operation corresponding to the unit is a normally used operation such as raising or lowering the slat 31, the light shielding device performs a special process to confirm whether the selection of the model of each unit received is correct. There is no need to do. When the user or the operator who performs the setting inputs an operation instruction corresponding to each unit, the selection of the model of each unit is erroneously confirmed by confirming that the slat part 3 stops in the middle of the operation. You can easily know that you are. Incorrect selection of the model of each unit means that the selection of the configuration of the light shielding device received by the control unit 1 is incorrect. Conversely, when the user or operator inputs an operation instruction corresponding to each unit, confirm that the slat part 3 operates as instructed to confirm that the selection of the model of each unit is correct. It is easy to know. In addition, when the slat unit 3 performs an operation according to a unit whose selection does not match the actual, the shading device operates the slat unit 3 until it becomes a state according to the model of the actual unit, and then stops. The user or the operator who performs the setting can easily know the actual model of each unit by checking the state of the slat part 3 such as the position where the slat 31 is stopped. Therefore, the user or the operator who performs the setting can prepare to properly set the light shielding device by appropriately changing the selection of the model of each unit.

  In the present embodiment, the mode in which the operation of the slat part 3 is controlled so that the slat part 3 is in a state corresponding to the actual model of each unit is shown. It is not limited. The shading device is not related to the actual model of each unit, such as stopping the slat 31 at an intermediate position between the upper limit and the lower limit when the selection of the model of each unit does not match the actual one. The form which controls operation | movement of the slat part 3 so that it may be in a predetermined state may be sufficient. In the case of this form, the control processing unit 11 does not need to perform a process of determining the actual model of each unit. Also in this form, the user or the operator can easily know that the selection of the model of each unit is wrong by confirming that the light shielding device stops halfway.

  Further, in the present embodiment, a mode in which selection of a model is received for each of a plurality of units included in the light shielding device using a plurality of selection switches has been described. However, the light shielding device of the present invention includes a plurality of units. The form which accepts selection of a model collectively may be sufficient. For example, the light shielding device may include a single selection switch, and may accept a selection of any one combination from a plurality of predetermined combinations of units of each model using the selection switch. . The shading device may be configured to accept an input of an instruction to select the model of each unit by the operation of a user or an operator, instead of accepting the selection of the configuration using the selection switch. . Further, in the present embodiment, the form in which the plurality of slats 31 are moved in the vertical direction is shown.
