Fig.10 The monitoring screen is shown when a screen split cancellation operation is input in a state where the first data display section and the second data display section are displayed in the data display area.

[0028] like Figure 1 As shown in FIG. 1 , the injection molding machine 1 according to the present embodiment has a molding machine body 10, which includes a mold clamping device 2, an injection device 3, and a take-out device 4. The molding machine body 10 is disposed on a base 5. In addition, the injection molding machine 1 has a sensor group 6 ( Figure 2 ), and a control unit 7 that controls the molding machine body 10.

[0029] The mold clamping device 2 opens, closes, and clamps the fixed mold 81 and the movable mold 82. The fixed mold 81 and the movable mold 82 form a cavity 83.

[0030] The mold clamping device 2 includes a fixed mold plate 21, a movable mold plate 22, and a mold clamping drive mechanism 23. The fixed mold plate 21 is provided with a fixed mold 81. The movable mold plate 22 is provided with a movable mold 82. The mold clamping drive mechanism 23 includes, for example, an electric motor, a ball screw mechanism, and a toggle mechanism. The mold clamping drive mechanism 23 moves the fixed mold 81 and the movable mold 82 in the front-rear direction (in the middle) through the fixed mold plate 21 and the movable mold plate 22. Figure 1 The mold is pressed tightly (left and right direction in the middle) to generate mold clamping force.

[0031] The injection device 3 includes a cylinder 31 , a nozzle 32 , a resin supply unit 33 , a heater 34 , a screw 35 , and a screw drive mechanism 36 .

[0032] The cylinder 31 has a cylindrical shape. The cylinder 31 is arranged in the front-to-back direction. The nozzle 32 is arranged at the front end of the cylinder 31. The resin supply unit 33 is arranged at the rear end of the cylinder 31. The resin supply unit 33 has a hopper for containing a powdered or granular resin that becomes a material for a molded product. The resin supply unit 33 supplies resin to the cylinder 31. The heater 34 is, for example, a belt heater, and is arranged on the outer peripheral surface of the cylinder 31. The screw 35 is accommodated in the cylinder 31 in a manner that allows it to rotate and move forward and backward. The screw drive mechanism 36 has, for example, an electric motor and a ball screw mechanism. The screw drive mechanism 36 causes the screw 35 to rotate and move forward and backward.

[0033] The removal device 4 includes an ejector pin (not shown) and a protrusion mechanism 41. The protrusion mechanism 41 includes, for example, an air cylinder. The protrusion mechanism 41 drives the ejector pin to remove the molded product from the movable side mold 82.

[0034] The sensor group 6 is composed of a plurality of sensors disposed at various parts of the molding machine body 10. The sensor group 6 includes, for example, a sensor for detecting the position and speed of the screw 35, a sensor for detecting the rotation speed of the screw 35, a sensor for detecting the pressure (injection pressure, holding pressure, back pressure) of the resin applied to the cylinder 31, a sensor for detecting the amount of mold opening and closing, a sensor for detecting the mold clamping pressure, a sensor for detecting the pressure (mold internal pressure) of the resin applied to the cavity 83, a sensor for detecting the amount of protrusion of the ejector pin, a sensor for detecting the pressure applied to the ejector pin, a sensor for detecting the temperature of various parts of the molding machine body 10, and a sensor for detecting a power value.

[0035] The control unit 7 manages the overall operation of the injection molding machine 1. Figure 2 As shown, the control unit 7 includes a display device 71, an input device 72, a storage device 73, a timer 74, and a control device 75. The control unit 7 is a data display device that displays a plurality of data related to the operation of molding a molded product (molding operation).

[0036] The display device 71 is, for example, a flat panel display such as a liquid crystal display.

[0037] The input device 72 is, for example, an operation key or a touch panel. The operation key is, for example, a key of a hardware keyboard. The touch panel is arranged to overlap the display surface of the display device 71, and is combined with a button graphic or a scroll bar graphic displayed on the display surface to form a soft key. Touching a portion of the touch panel corresponding to a button graphic or sliding a scroll bar graphic is equivalent to operating a soft key, that is, inputting an operation to the input device 72.

[0038] The storage device 73 is, for example, a magnetic disk device or a nonvolatile memory, etc. The storage device 73 stores information related to molding conditions, etc. In addition, the storage device 73 stores data measured by the sensor group 6 .

[0039] The control device 75 has a computer. The control device 75 is connected to the display device 71, the input device 72, the storage device 73, and the timer 74 in a communicable manner. The control device 75 displays various information on the display device 71 and performs actions corresponding to the operation input to the input device 72. It should be noted that the display device 71 and the input device 72 may also be a tablet device or a laptop computer connected to the control device 75 via wireless communication. In addition, the control device 75 is connected to the sensor group 6.

[0040] The control device 75 is communicatively connected to the mold clamping drive mechanism 23, the heater 34, the screw drive mechanism 36, and the protruding mechanism 41. The control device 75 controls the mold clamping drive mechanism 23, the heater 34, the screw drive mechanism 36, and the protruding mechanism 41 during the molding operation.

[0041] Next, an example of the molding operation executed by the control device 75 will be described.

[0042] The control device 75 controls the heater 34 to heat the cylinder 31 to a predetermined temperature. The control device 75 performs a purge operation and metering of the resin for the initial injection amount before the molding operation is performed.

[0043] During the molding operation, the control device 75 controls the mold clamping drive mechanism 23 to press the movable side mold 82 against the fixed side mold 81 to perform mold clamping (mold closing operation). Next, the control device 75 controls the screw drive mechanism 36 to advance the screw 35 (injection operation (filling)). As a result, the plasticized resin at the front end of the cylinder 31 is filled into the mold cavity 83. Next, the control device 75 controls the screw drive mechanism 36 to advance and retreat the screw 35 to apply a specified pressure (holding pressure) to the resin in the mold cavity 83 (injection operation (holding pressure)).

[0044] Next, the control device 75 controls the screw drive mechanism 36 so that the screw 35 rotates and retreats, and supplies (meters) the amount of resin required for one injection to the front end of the cylinder 31 (metering action). The metering action is also called the plasticizing action. In parallel with the metering action, the control device 75 waits until the resin in the mold cavity 83 cools and solidifies (cooling action).

[0045] Then, when the cooling action is completed, the control device 75 controls the mold closing drive mechanism 23 to open the fixed side mold 81 and the movable side mold 82 (mold opening action), and controls the protrusion mechanism 41 to remove the molded product from the mold cavity 83 through the ejector pin (removal action).

[0046] From the mold closing action to the removal action is one molding action. The control device 75 repeatedly performs the molding action to mold the molded product. One molding action is also called one injection.

[0047] The control device 75 measures a plurality of data using the sensor group 6 and the timer 74 during the execution of the molding action. The control device 75 associates the plurality of data (a plurality of measured data) measured in one molding action with the number of shots and the reference time of the molding action, and stores them in the data storage area 73a of the storage device 73. The plurality of measured data includes the actual measurement data measured using the sensor group 6 and the time data measured (timed) using the timer 74. The number of shots increases by 1 each time the molding action is executed. The number of shots is the number of times the molding action is executed, and is also the molding action number indicating the order of the molding action executed. The reference time is, for example, the start time of the mold closing action. The number of shots, the plurality of measured data, and the reference time are data related to the molding action. The control device 75 associates the plurality of data related to one molding action with each other as a data set Ds, and stores the data set Ds in the order of the reference time (time series order) in the data storage area 73a. The data storage area 73a can store a predetermined number of data sets Ds (for example, 100,000 times). When the data storage area 73a becomes full, the control device 75 overwrites the oldest data set Ds with a new data set Ds.

[0048] Figure 3 An example of a plurality of data related to the molding operation stored in the data storage area 73a is shown in FIG. Figure 3 In , multiple data contained in a row constitute a data set Ds, and the data sets Ds are arranged from top to bottom in the order of the latest and oldest reference times. Figure 3 In the table, the measurement data are arranged from left to right in the order of monitoring item numbers (described later).

[0049] The control unit 7 has a monitoring screen for displaying a plurality of data related to the molding operation, and a monitoring item selection screen for selecting a monitoring item, wherein the monitoring item indicates the type of data displayed on the monitoring screen. The control device 75 displays the monitoring screen and the monitoring item selection screen on the display device 71. On the monitoring screen, data corresponding to the monitoring item pre-selected by the operator using the monitoring item selection screen is displayed. During the molding operation, a plurality of data related to the molding operation is displayed on the monitoring screen in substantially real time.

[0050] Figure 4 An example of a monitoring item selection screen Gn is shown. The monitoring item selection screen Gn includes a monitoring item table Gn1 and a monitoring item selection Gn2. The monitoring item table Gn1 displays a list of monitoring items that can be selected by the operator. The monitoring item name and number (monitoring item number) of each monitoring item are displayed side by side in the monitoring item table Gn1. The monitoring item number displayed on the monitoring screen is set in the monitoring item selection Gn2.

[0051] Figures 5 to 10 An example of the monitoring screen G is shown. The monitoring screen G includes a setting display section Gs, a statistics display section Gt, a statistical injection number display section Gh, a first data display section G1, and a second data display section G2. In addition, the monitoring screen G includes a screen split display switching button B1 and a statistics clear button B2 as soft keys.

[0052] The setting display unit Gs is arranged at the upper part of the monitoring screen G. Setting information related to a plurality of pre-selected monitoring items is displayed on the setting display unit Gs. On the setting display unit Gs, "monitoring item name", "unit", "setting value", "max (maximum value)", and "min (minimum value)" related to each monitoring item are displayed in order from top to bottom. "Max" in the setting display unit Gs is the upper limit value of the normal range of the data measured for the monitoring item. "Min" in the setting display unit Gs is the lower limit value of the normal range of the data measured for the monitoring item.

[0053] The statistical display unit Gt is arranged at the lower part of the monitoring screen G. Statistical information related to a plurality of pre-selected monitoring items is displayed on the statistical display unit Gt. On the statistical display unit Gt, "max (maximum value)", "min (minimum value)", "range = R", "average = X", "deviation = σ", "R / X [%]", and "3σ / X [%]" related to each monitoring item are displayed in order from top to bottom. "max" in the statistical display unit Gt is the maximum value of the data measured for the monitoring item. "min" in the statistical display unit Gt is the minimum value of the data measured for the monitoring item. "Range = R" is a value obtained by subtracting "min" from "max". "Average = X" is the average value of the data measured for the monitoring item. "Deviation = σ" is the standard deviation of the data measured for the monitoring item. "R / X [%]" is a value obtained by dividing "range = R" by "average = X". "3σ / X [%]" is a value obtained by dividing 3 times the standard deviation of the data measured for the monitoring item by "average = X".

[0054] The statistical shot number display part Gh is arranged on the right side of the statistical display part Gt. The statistical shot number display part Gh displays the shot number (the number of molding operations) for statistics.

[0055] The monitoring screen G has a data display area D ( Figure 5The data display area D can display the first data display part G1 and the second data display part G2. The monitoring screen G has a single screen display state S1 and a split screen display state S12. The single screen display state S1 is a state in which only the first data display part G1 is displayed in the entire data display area D, and the split screen display state S12 is a state in which the first data display part G1 and the second data display part G2 are displayed in the data display area D.

[0056] The first data display part G1 is displayed in the data display area D. A plurality of data related to the molding operation is displayed on the first data display part G1. A data set Ds (in Figure 5 A plurality of data sets Ds (a plurality of data sets surrounded by dotted lines in the figure) are displayed in one row. One data set Ds includes the number of injections, a plurality of data (measurement data) measured for a plurality of pre-selected monitoring items, and a reference time of a molding action, and these data sets are sequentially displayed from left to right on the first data display part G1. In addition, on the first data display part G1, a plurality of data sets Ds are displayed from top to bottom in the order of the new and old reference times. That is, the reference time of the data set Ds displayed at the top is newer than the reference time of the data set Ds displayed at the bottom. The first data display part G1 has a scroll bar SB as a soft key, which is configured to be able to scroll the plurality of data sets Ds in the up-down direction. The plurality of data sets Ds displayed on the first data display part G1 scroll in the up-down direction in accordance with the sliding of the scroll bar SB. Sliding the scroll bar SB is equivalent to an operation of scrolling the plurality of data sets Ds displayed on the first data display part G1 in the up-down direction. The plurality of data sets Ds displayed on the first data display part G1 may also be able to scroll in the left-right direction. On the first data display section G1, the measured data that exceeds the normal range is highlighted (when a value other than 0 is set for "max" or "min" of the setting display section Gs). It should be noted that the dot-dash line representing the data display area D and the dotted line representing the data set Ds are only displayed in the Figure 5 However, regarding the data display area D and the data set Ds, Figures 6 to 10 The same is true in .

[0057] The second data display part G2 is displayed below the first data display part G1 in the data display area D. The second data display part G2 displays a plurality of data related to the molding operation. The second data display part G2 has the same structure as the first data display part G1, so detailed description is omitted.

[0058] The screen split display switching button B1 is arranged above the setting display part Gs in the monitoring screen G.

[0059] If the screen split display switching button B1 is touched in the single screen display state S1, the control device 75 displays the first data display part G1 and the second data display part G2 in a vertical arrangement in the data display area D, and switches to the split screen display state S12. It should be noted that touching the screen split display switching button B1 in the single screen display state S1 is equivalent to inputting a screen split operation to the input device 72.

[0060] If the split screen display switching button B1 is touched in the split screen display state S12, the control device 75 clears the second data display part G2, displays only the first data display part G1 in the data display area D, and switches to the single screen display state S1. Touching the split screen display switching button B1 in the split screen display state S12 is equivalent to inputting a screen split release operation to the input device 72.

[0061] The statistics clear button B2 is arranged on the right side of the statistics display part Gt and below the statistics injection number display part Gh. When the statistics clear button B2 is touched, the injection number is cleared, the statistics injection number display part Gh becomes 0, and the statistics information of the statistics display part Gt is reset.

[0062] Next, refer to Figures 5 to 10 The monitoring screen G displayed on the display device 71 by the control device 75 during the molding operation will be described.

[0063] The control device 75 continuously executes the molding operation, measures a plurality of data related to the molding operation, and stores the data in the data storage area 73 a of the storage device 73 .

[0064] During the molding operation, when the operator inputs an operation to display the monitoring screen G to the input device 72, the control device 75 displays the monitoring screen G on the display device 71 ( Figure 5 ). At this time, the control device 75 displays only the first data display part G1 in the data display area D (single screen display state S1). In addition, the control device 75 reads the data set Ds from the data storage area 73a, arranges the data set Ds with the latest reference time in the top row of the first data display part G1, and arranges and displays the plurality of data sets Ds in the order of the latest and oldest reference times from top to bottom on the first data display part G1.

[0065] When the forming action in the process of execution is completed and the new data set Ds related to the forming action is stored in the data storage area 73a, the control device 75 reads the new data set Ds from the data storage area 73a. At this time, the read data set Ds is the latest data set Ds. Then, the control device 75 moves the multiple data sets Ds displayed on the first data display part G1 downward by one row, and displays the new data set Ds read from the data storage area 73a on the top row of the first data display part G1 ( Figure 6 ).

[0066] When the operator slides the scroll bar SB of the first data display portion G1 in the up-down direction, the control device 75 scrolls the plurality of data sets Ds displayed on the first data display portion G1 in the up-down direction in accordance with the sliding ( Figure 7 ).like Figure 7 As shown, by this sliding operation, a data set Ds including a plurality of older data related to the molding operation is displayed in the first data display section G1.

[0067] When the operator touches the split screen display switching button B1 in the single screen display state S1, the control device 75 performs the following actions: (A) the lower end of the first data display part G1 is moved upward (near the center of the data display area D in the vertical direction) to reduce the size of the first data display part G1 in the vertical direction, and the second data display part G2 with the same size in the vertical direction as the first data display part G1 is displayed below the first data display part G1; (B) the data set Ds is read from the data storage area 73a, the latest data set Ds is arranged in the top row of the first data display part G1, and a plurality of data sets Ds are arranged and displayed on the first data display part G1 from top to bottom in the order of the newest and the oldest at the reference time; (C) the data set Ds is read from the data storage area 73a, and a plurality of data sets Ds are arranged and displayed on the second data display part G2 from top to bottom in the order of the newest and the oldest at the reference time. The plurality of data sets Ds are the data sets displayed on the first data display part G1 immediately before the split screen display switching button B1 is touched ( Figure 8 ). Thus, the single-screen display state S1 is switched to the split-screen display state S12.

[0068] At this time, the plurality of data sets Ds displayed on the second data display part G2 are displayed at the position D2 ( Figure 7In this way, the positions of the plurality of data sets Ds displayed on the first data display section G1 before the screen split display switching button B1 is touched remain unchanged and are displayed on the second data display section G2. This can prevent the operator from losing sight of the data set Ds of interest due to the change in the position of the data set Ds. It should be noted that when the second data display section G2 is displayed, the control device 75 can also display the data set Ds at a position other than the position D2 of the first data display section G1 on the second data display section G2.

[0069] When the operator slides the scroll bar SB of the first data display part G1 in the up-down direction, the control device 75 scrolls the plurality of data sets Ds displayed on the first data display part G1 in the up-down direction in accordance with the sliding. When the operator slides the scroll bar SB of the second data display part G2 in the up-down direction, the control device 75 scrolls the plurality of data sets Ds displayed on the second data display part G2 in the up-down direction in accordance with the sliding.

[0070] When the forming action in progress in the split screen display state S12 is completed and the new data set Ds related to the forming action is stored in the data storage area 73a, the control device 75 performs the following actions: (D) reads out the next new data set Ds of the data set Ds displayed on the top row of the first data display part G1 from the data storage area 73a; (E) moves the multiple data sets Ds displayed on the first data display part G1 downward by one row, and displays the data set Ds read out from the data storage area 73a on the top row of the first data display part G1; (F) maintains the display of the multiple data sets Ds on the second data display part G2 ( Fig. 9 ).

[0071] Specifically, (i) when the latest data set Ds is displayed on the top row of the first data display part G1, if the forming action in execution is completed and the new data set Ds related to the forming action is stored in the data storage area 73a, the control device 75 reads the new data set Ds from the data storage area 73a, moves the multiple data sets Ds displayed on the first data display part G1 downward by one row, and displays the new data set Ds read from the data storage area 73a on the top row of the first data display part G1. The control device 75 maintains (does not change) the display of the multiple data sets Ds on the second data display part G2.

[0072] Alternatively, (ii) when a data set Ds older than the latest data set Ds is displayed on the top row of the first data display part G1, if the forming action in execution is completed and the new data set Ds related to the forming action is stored in the data storage area 73a, the control device 75 reads out the next new data set Ds (target data set Dst) of the old data set Ds displayed on the top row of the first data display part G1 from the data storage area 73a, moves the multiple data sets Ds displayed on the first data display part G1 downward by one row, and displays the target data set Dst read out from the data storage area 73a on the top row of the first data display part G1. The control device 75 maintains (does not change) the display of the multiple data sets Ds on the second data display part G2.

[0073] That is, each time the forming action in the process of execution is completed, the multiple data sets Ds displayed on the first data display part G1 automatically scroll downward line by line, and the multiple data sets Ds displayed on the second data display part G2 remain unchanged. It should be noted that the control device 75 performs the actions related to the first data display part G1 shown in (i) and (ii) above in either the single-screen display state S1 or the split-screen display state S12.

[0074] When the operator touches the split screen display switching button B1 in the split screen display state S12, the control device 75 performs the following actions: (G) clears the second data display part G2, moves the lower end of the first data display part G1 downward (toward the lower end of the data display area D) to increase the size of the first data display part G1 in the vertical direction; (H) reads the data set Ds from the data storage area 73a, arranges the latest data set Ds in the top row of the first data display part G1, and displays a plurality of data sets Ds in the order of the newest and the oldest reference time from the top to the bottom on the first data display part G1. Thus, the split screen display state S12 is switched to the single screen display state S1. Figures 5 to 7 , Fig.10 The monitoring screen G in the single-screen display state S1 is shown. Figure 8 , Fig. 9 The monitoring screen G in the split screen display state S12 is shown.

[0075] Every time a molding action in the execution process is completed, the control device 75 updates the statistical information displayed on the statistical display part Gt and the number of injections displayed on the statistical injection number display part Gh.

[0076] As described above, the injection molding machine 1 includes a molding machine body 10 for molding a molded product and a control unit 7. The control unit 7 is a data display device that displays a plurality of data related to a molding operation. The control unit 7 includes a display device 71 that displays a monitoring screen G, an input device 72 for an operator to input an operation, and a control device 75. The monitoring screen G includes a data display area D that can display a first data display portion G1 and a second data display portion G2. On the first data display portion G1 and the second data display portion G2, a data set Ds including a plurality of data related to one molding operation is displayed in a row, and the plurality of data sets Ds are displayed in a time series order in the vertical direction.

[0077] When only the first data display part G1 is displayed in the data display area D (single-screen display state S1), when the screen split display switch button B1 is touched, the control device 75 reduces the size of the first data display part G1 in the vertical direction, and arranges the second data display part G2 and the first data display part G1 in the vertical direction in the data display area D.

[0078] When the split screen display switch button B1 is touched in the state where the first data display part G1 and the second data display part G2 are displayed in the data display area D (split screen display state S12), the control device 75 clears the second data display part G2 and increases the size of the first data display part G1 in the vertical direction.

[0079] Thus, the first data display part G1 and the second data display part G2 can be displayed in the data display area D of the monitoring screen G, and the data set Ds including a plurality of data related to the molding operation can be displayed on each data display part. Therefore, by displaying the data set Ds including a plurality of data related to one molding operation on the first data display part G1 and displaying the data set Ds including a plurality of data related to another molding operation on the second data display part G2, these data can be easily compared without comparing the data while scrolling in the up-down direction. Therefore, the complicated operation of comparing the data while scrolling in the up-down direction is unnecessary.

[0080] In addition, when the split screen display switching button B1 is touched in the single screen display state S1, the control device 75 performs the following actions: (A) the lower end of the first data display part G1 is moved upward to reduce the size of the first data display part G1 in the vertical direction, and the second data display part G2 is displayed below the first data display part G1; (B) a plurality of data sets Ds are displayed in the first data display part G1 in the order of the newest data set Ds arranged from top to bottom in the first data display part G1, with the latest data set Ds arranged in the top row; (C) a plurality of data sets Ds are displayed in the order of the newest data set Ds arranged from top to bottom in the second data display part G2, the plurality of data sets Ds being the data sets displayed on the first data display part G1 immediately before the split screen display switching button B1 is touched. Thus, immediately after the single screen display state S1 is switched to the split screen display state S12, a plurality of data sets Ds including the latest data set Ds are displayed on the first data display part G1, and a plurality of data sets Ds displayed on the first data display part G1 immediately before the switch is switched are displayed on the second data display part G2. Therefore, it is possible to easily compare the plurality of data sets Ds including the latest data set Ds with the plurality of data sets Ds displayed in the first data display section G1 immediately before the switch.

[0081] In addition, a plurality of data related to the molding operation is stored in the storage device 73 (data storage area 73a). When a new data set Ds is stored in the storage device 73 in the split screen display state S12, the control device 75 performs the following operations: (D) reads out a new data set Ds next to the data set Ds displayed on the top row of the first data display part G1 from the storage device 73; (E) moves the plurality of data sets Ds displayed on the first data display part G1 downward by one row, and displays the data set Ds read out from the storage device 73 on the top row of the first data display part G1; (F) maintains the display of the plurality of data sets Ds on the second data display part G2. Thus, each time the molding operation in progress is completed, the plurality of data sets Ds displayed on the first data display part G1 are automatically scrolled downward row by row, and the plurality of data sets Ds displayed on the second data display part G2 remain unchanged. Therefore, the plurality of data sets Ds displayed on the first data display part G1 and automatically updated and the plurality of data sets Ds displayed on the second data display part G2 and unchanged can be compared.

[0082] In addition, when the split screen display switching button B1 is touched in the split screen display state S12, the control device 75 performs the following actions: (G) the second data display part G2 is cleared, and the lower end of the first data display part G1 is moved downward to increase the size of the first data display part G1 in the vertical direction; (H) multiple data sets Ds are displayed in the first data display part G1 in the order of new and old from top to bottom in such a way that the latest data set Ds is arranged in the top row. Thus, just after the switch from the split screen display state S12 to the single screen display state S1, multiple data sets Ds including the latest data set Ds are displayed on the first data display part G1. Therefore, it is possible to confirm the multiple data sets Ds including the latest data set Ds that has just been switched.

[0083] In addition, the first data display part G1 has a scroll bar SB, and the scroll bar SB is used to input an operation of scrolling the plurality of data sets Ds displayed on the first data display part G1 in the up-down direction. The second data display part G2 has a scroll bar SB, and the scroll bar SB is used to input an operation of scrolling the plurality of data sets Ds displayed on the second data display part G2 in the up-down direction. That is, the first data display part G1 and the second data display part G2 are configured to enable the plurality of data sets Ds to be scrolled in the up-down direction. Thus, by scrolling the plurality of data sets Ds in the up-down direction, the first data display part G1 and the second data display part G2 can display the desired data sets Ds.
