(Input system) Fig. 1 is an explanatory diagram for explaining the structure of the input system of this embodiment. As shown in FIG. 1, the input system 100 includes a display device D1, a control device 101, a coordinate input device TP, and an operation knob 1, which is an operation support device. Here, one of the directions in the plan view of the display device D1 is the Dx direction, and the direction orthogonal to the Dx direction is the Dy direction.

In the display device D1, there are, for example, a display area MS, a display area LS, and a display area RS. The pointer PM is displayed on the display device D1.

The control device 101 is a so-called computer, which includes a CPU (Central Processing Unit) 102, a RAM (Random Access Memory) 103, a ROM (Read Only Memory) 104, and hardware An internal memory device 105 such as a hard disc drive (HDD: Hard Disc Drive). The coordinate input device TP is connected to the control device 101 as an input unit of the control device 101.

The BIOS (Basic Input Output System) and other programs are stored in the ROM104.

RAM103 is a main memory that can record and read programs and data. It provides a working area and stores multiple programs for controlling the display device D1 and the coordinate input device TP.

The CPU 102 reads and executes the program stored in the RAM 103, and outputs the calculation result to the internal memory device 105 and the like.

In the CPU 102, a display device D1 is used to display an image that has undergone arithmetic processing required to display graphics. In the CPU 102, the coordinate input device TP can also be used to display an image that has undergone arithmetic processing required to display a figure. The control device 101 can also be constituted by a touch panel controller dedicated to capture the signal from the coordinate input device TP and arithmetic processing, and a computer that performs the arithmetic processing required to display the graphics on the display device D1.

The coordinate input device TP is a so-called touch panel having, for example, a display function and a coordinate input function. The coordinate input device TP can display images in the XY plane and accept changes in electrostatic capacitance as coordinate input.

The operation knob 1 is an operation support device of the coordinate input device TP. The coordinates of the XY plane of the operation knob 1 are detected by the coordinate input device TP. In addition, the rotation operation R of the operation knob 1 is detected by the coordinate input device TP. In addition, the depression operation PP of the operation knob 1 is detected by the coordinate input device TP.

In the input system 100, the pointer PM is moved to any one of the display area MS, the display area LS, and the display area RS by, for example, the rotation operation R of the operation knob 1.

Fig. 2 is a plan view showing the back of the operation support device of this embodiment. Fig. 3 is a cross-sectional view for explaining the state in which the operating member is not depressed in the section along the line III-III' in Fig. 2. Fig. 4 is a cross-sectional view for explaining the state in which the operating member is not depressed in the section taken along the line IV-IV' in Fig. 2. Fig. 5 is a cross-sectional view for explaining the state in which the operating member is not depressed in the cross section of the line V-V' in Fig. 2. Figure 6 is a top view showing the plane of the support plate. Fig. 7 shows a top view of the first rotating plate.

As shown in FIG. 2, the operation knob 1 includes a spindle supporting member 2, a supporting plate 4, a first rotating plate 5, a second rotating plate 6, three first members 53 and three second members 63. The first members 53 are arranged at intervals of 120° around the central axis Ax of the main shaft support member 2, for example. The second members 63 are arranged at intervals of 120° around the central axis Ax, for example.

As shown in FIG. 3, the spindle support member 2, the operating member 3, and the support plate 4 are fixed with an adhesive, a fixing pin, etc., and are integrated. The spindle supporting member 2 is a hollow cylindrical member. The spindle support member 2 is placed on the upper surface TPF of the coordinate input device TP. For example, the spindle support member 2 is formed of insulating resin. Thereby, even if it is placed on the upper surface TPF of the coordinate input device TP, the coordinate input device TP does not detect the spindle support member 2. The lower end of the spindle support member 2 is connected to the coordinate input device TP.

The operating member 3 has an annular upper surface plate covering the spindle support member 2, the support plate 4, and a side surface covering the first rotating plate 5 from the radially outer side.

As shown in FIGS. 2, 3, and 6, the support plate 4 is an annular plate-shaped member formed of insulating resin. The first magnet 8 is embedded in the upper surface of the support plate 4. The first magnets 8 are arranged side by side in the circumferential direction. The first magnet 8 is a member that can be molded in a small size, has high processing accuracy, and can be used in a wide temperature range, such as a neodymium magnet.

As shown in FIGS. 2 and 7, the first rotating plate 5 is an annular plate-shaped member. As shown in FIGS. 4, 5, and 7, a second magnet 9 is embedded on the upper surface of the first rotating plate 5. The second magnet 9 is a member that can be molded in a small size, has high processing accuracy, and can be used in a wide temperature range, such as a neodymium magnet. The second magnets 9 are arranged side by side in the circumferential direction. When the first magnet 8 and the second magnet 9 are located in a position overlapping up and down, they have different polarities facing each other. Thereby, since the first magnet 8 and the second magnet 9 are attracted to each other, an attractive force acts between the support plate 4 and the first rotating plate 5. When the operating member 3 is not depressed, the supporting plate 4 is in contact with the first rotating plate 5.

Since the support plate 4 exists between the first magnet 8 and the second magnet 9, the attractive force of the first magnet 8 and the second magnet 9 can be adjusted by the thickness of the support plate 4. Furthermore, the attractive force can also be adjusted by setting the size and the number of installations of the first magnet 8 and the second magnet 9.

The first rotating plate 5 is a conductive material with a permeability lower than that of carbon steel. In this embodiment, the first rotating plate 5 is formed of a copper-zinc alloy. If the first rotating plate 5 is made of a material with a permeability of carbon steel or higher, it will form a magnetic circuit that hinders the gravitational force between the first magnet 8 and the second magnet 9, and may cause the tactile sensation along with the rotation of the operating knob 1 The feedback disappeared. The first rotating plate 5 may be an insulating material, but if it is a conductive material, the sensitivity of the first member 53 can be improved in the coordinate input device TP.

As shown in FIG. 2, the second rotating plate 6 is arranged on the radially inner side of the first rotating plate 5 and is a circular plate-shaped member. The second rotating plate 6 may be an insulating material, but if it is a conductive material, the sensitivity of the second member 63 can be improved in the coordinate input device TP.

As shown in FIG. 2, a plurality of connecting members 7 are provided in the circumferential direction, and they are columnar members extending toward the central axis Ax. For example, the connecting member 7 is a male screw made of metal. As shown in FIGS. 2 and 3, the connecting member 7 connects the side surface of the operating member 3 and the first rotating plate 5 by penetrating the side surface of the operating member 3 and the first rotating plate 5. The end portion of the connecting member 7 protruding from the radially inner side of the first rotating plate 5 is inserted into the groove 6G provided on the lower surface of the second rotating plate 6. Thereby, the connecting member 7 connects the first rotating plate 5 and the second rotating plate 6 in accordance with the rotating operation R of the operating knob 1.

As shown in FIG. 4, the first member 53 is attached to the coordinate input device TP side of the first rotating plate 5. The first member 53 protrudes from the first rotating plate 5 toward the coordinate input device TP. The first member 53 has a cylindrical shaft portion 51 that does not affect the detection sensitivity of the coordinate input device TP, and a disc-shaped end portion 52 having a size suitable for the detection sensitivity of the coordinate input device TP. The first member 53 is a conductive member, and is formed of, for example, a copper-zinc alloy.

As shown in FIG. 5, the second member 63 is attached to the coordinate input device TP side of the second rotating plate 6. The second member 63 protrudes from the second rotating plate 6 toward the coordinate input device TP. The second member 63 has a cylindrical shaft portion 61 that does not affect the detection sensitivity of the coordinate input device TP, and a disc-shaped end portion 62 having a size suitable for the detection sensitivity of the coordinate input device TP. The second member 63 is a conductive member, and is formed of, for example, a copper-zinc alloy.

If the first rotating plate 5, the operating member 3, and the connecting member 7 are conductive members, the first member 53 is easily conducted with the operator via the connecting member 7, the first rotating plate 5, and the operating member 3, and the coordinate input device TP is easy to detect To the first member 53 contact.

As shown in FIG. 2, the first member 53 is arranged at a position deviated by 60° from the second member 63 around the central axis Ax. The first member 53 may be arranged at the same position as the second member 63 in the circumferential direction around the central axis Ax. In the present embodiment, the first member 53 is located at a position other than the line connecting the central axis Ax of the spindle support member 2 and the second members 63. By arranging the first member 53 at a different position from the second member 63 in the circumferential direction around the central axis Ax, even if the sizes of the end 52 and the end 62 are enlarged, they can be arranged without interference with each other.

As shown in FIGS. 4 and 5, when the operating member 3 is not depressed, the end 62 of the second member 63 is closer to the coordinate input device TP than the end 52 of the first member 53. In the state where the operating member 3 is not depressed, a gap is formed between the end 52 of the first member 53 and the input coordinate device TP. In the state where the support plate 4 is in contact with the first rotating plate 5, the sensitivity of the coordinate input device TP is set to not detect the end 52 of the first member 53.

Fig. 8 is a cross-sectional view for explaining the state in which the operating member is depressed in the section taken along the line III-III' in Fig. 2. Fig. 9 is a cross-sectional view for explaining the state in which the operating member is depressed in the section taken along the line IV-IV' in Fig. 2. Fig. 10 is a cross-sectional view for explaining the state in which the operating member is depressed in the cross section along the line V-V' in Fig. 2. In the state where the operating member 3 is depressed, as shown in FIG. 8, the supporting plate 4 is separated from the first rotating plate 5.

In other words, the distance between the spindle support member 2 and the operating part 3 when the first rotating plate 5 is in contact with the support plate 4 is greater than the distance between the spindle support member 2 and the operating member 3 when the first rotating plate 5 and the support plate 4 are separated The distance between.

Even if the supporting plate 4 is separated from the first rotating plate 5, the end portion of the connecting member 7 is inserted into the groove 6G provided on the lower surface of the second rotating plate 6. Thereby, in the state where the operating member 3 is depressed, even if the operating member 3 rotates, the first rotating plate 5 and the second rotating plate 6 rotate in conjunction with the rotating of the operating member 3.

As shown in Figures 9 and 10, if the state from which the operating member 3 is not depressed becomes the state where the operating member 3 is depressed, the distance between the end 52 of the first member 53 and the coordinate input device TP, and the second The difference in the distance between the end 62 of the member 63 and the coordinate input device TP becomes smaller. Thereby, if the coordinate input device TP detects the end 62 of the second member 63, the end 52 of the first member 53 is also detected. In this embodiment, in a state where the operating member 3 is depressed, the end 52 of the first member 53 is in contact with the coordinate input device TP.

As described above, since the first magnet 8 and the second magnet 9 are attracted to each other, an attractive force acts between the support plate 4 and the first rotating plate 5. Therefore, when the downward pressing operation PP of the operating knob 1 is released, the first rotating plate 5 is attracted to the supporting plate 4 and returns to the state where the operating member 3 shown in FIGS. 3 to 5 is not pressed.

The operation knob 1 can support the following operations. Fig. 11A is a plan view showing the positions of the plural members at the first rotation angle when the operating member is not depressed. Fig. 11B is a plan view showing the positions of the plural members at the first angle of rotation when the operating member is depressed.

For example, as shown in FIG. 11A, in a state where the operating member 3 is not depressed, three second members 63 are detected in the coordinate input device TP. The control device 101 can calculate the coordinates of the central axis Ax from the coordinates of the three second members 63. For example, by setting the coordinates of the operating knob 1 to the coordinates of the central axis Ax, the control device 101 can obtain the position of the operating knob 1 in the XY plane.

The operation knob 1 is an operation support device that supports input operations to the coordinate input device TP that detects changes in electrostatic capacitance. The operation knob 1 includes a spindle support member 2, an operation member 3, a support plate 4, a first rotating plate 5, a second rotating plate 6, a first member 53 and a second member 63 placed on the coordinate input device TP. The supporting plate 4 protrudes toward the radially outer side of the spindle supporting member 2, a plurality of first magnets 8 are arranged in the circumferential direction of one surface, and are fixed to the spindle supporting member 2. The operating member 3 covers the support plate 4 and the spindle support member 2. The first rotating plate 5 is arranged at a position overlapping with the first magnet 8 in the circumferential direction of one surface of the first rotating plate 5, and a plurality of second magnets 9 that generate gravitational force on the first magnet 8 are arranged on the supporting plate 4 The TP side of the coordinate input device. The second rotating plate 6 is arranged on the radially inner side of the first rotating plate 5 and on the side of the coordinate input device TP of the supporting plate 4. The first member 53 is a conductive member protruding from the first rotating plate 5 toward the coordinate input device TP. The second member 63 is a conductive member protruding from the second rotating plate 6 toward the coordinate input device TP.

As shown in Fig. 1, if the PP is pressed down by the operating knob 1, the distance between the end 52 of the first member 53 and the coordinate input device TP, and the distance between the end 52 of the first member 53 and the coordinate input device TP, and the distance between the second member 63 The difference in the distance between the end 62 and the coordinate input device TP becomes smaller. As a result, three second members 63 and three first members 53 are detected in the coordinate input device TP.

In addition, if the operating member 3 is obliquely depressed, one or two first members 53 are detected, so the control device 101 does not recognize it as the operating knob 1 depressing the PP. If the operating member 3 is depressed, and three first members 53 are detected, the control device 101 assumes that the operation knob 1 depresses the operation PP, and only needs to execute the processing assigned to the operation knob 1 depresses the operation PP. Suppress the processing in the wrong operation.

As shown in FIG. 11A, the direction in which each second member 63 exists from the central axis Ax is referred to as a direction A, a direction B, and a direction C. Fig. 11C is a plan view showing the positions of the plural members at the second rotation angle when the operating member is not depressed. When the operating knob 1 is rotated counterclockwise from the first rotation angle shown in FIG. 11A to the second rotation angle shown in FIG. 11C, the control device 101 calculates the direction of the azimuth A from the central axis Ax in FIG. 11A, and The angle difference in the direction of the azimuth A from the central axis Ax of FIG. 11C can be used to obtain the rotation angle of the operating knob 1. In addition, the bearing A has been described, but the calculation based on the bearing A can be replaced with the calculation based on the bearing B or the bearing C.

In addition, in the operation knob 1, a plurality of second magnets 9 are arranged in the circumferential direction of one surface of the first rotating plate 5 at positions that overlap the first magnet 8 up and down, and generate an attractive force to the first magnet 8.

Thereby, if there is no rotating operation R of the operating knob 1, the relative rotation position of the first rotating plate 5 and the supporting plate 4 is maintained by the attractive force of the first magnet 8 and the second magnet 9. By the rotating operation R of the operating knob 1, the operating member 3 rotates relative to the spindle supporting member 2. At the position overlapping with the first magnet 8 up and down, the second magnet 9 that generates attraction to the first magnet 8 moves and generates attraction to the next adjacent first magnet 8, thereby transmitting the accompanying operation knob to the operator of the operation knob 1. The tactile feedback of 1 rotation operation R. That is, with the rotation operation R of the operation knob 1, a tactile sensation called a click feeling is transmitted to the operator of the operation knob 1.

Fig. 11D is a plan view showing the positions of the plural members at the second rotation angle when the operating member is depressed. As shown in FIG. 11D, when the coordinate input device TP detects three second members 63 and three first members 53, it is also possible to calculate the direction of the orientation A from the central axis Ax in FIG. 11A, and The angle difference in the direction of the direction A from the central axis Ax of 11D obtains the rotation angle of the operation knob 1.

The coordinate input device TP can also detect the clockwise rotation of the operating knob 1. Fig. 11E is a plan view showing the positions of plural members at the third rotation angle when the operating member is not depressed. When the operating knob 1 is rotated clockwise from the first rotation angle shown in FIG. 11A to the third rotation angle shown in FIG. 11E, the control device 101 calculates the direction of the azimuth A from the central axis Ax in FIG. 11A, The angle difference between the direction of the azimuth A from the central axis Ax in FIG. 11D and the rotation angle of the operating knob 1 can be obtained. In addition, the bearing A has been described, but the calculation based on the bearing A may be replaced with the calculation based on the bearing B or the bearing C.

Fig. 11F is a plan view showing the positions of multiple members at the third angle of rotation when the operating member is depressed. As shown in FIG. 11F, when the coordinate input device TP detects the situation of three second members 63 and three first members 53, it can also be calculated by calculating the direction of the azimuth A from the central axis Ax of FIG. 11A, and that of FIG. 11F The angle difference of the direction A from the central axis Ax is used to obtain the rotation angle of the operating knob 1.

(Variation example) Fig. 12 is a cross-sectional view showing a modification of this embodiment. Fig. 13 is a cross-sectional view showing a modification of this embodiment. The same components as those described in this embodiment described above are denoted by the same reference numerals, and repeated descriptions are omitted.

As shown in Figures 12 and 13, the operating knob of the modified example of this embodiment may not have the second rotating plate 6 and the three second members 63. The ends 52 of the three first members 53 are placed on the coordinate input device The upper surface of TP is TPF.

The operating member 3 of the operating knob of the modified example of this embodiment cannot be depressed. The operation knob of the modified example of this embodiment is an operation support device that supports the input operation of the coordinate input device TP that detects the change of the electrostatic capacitance. The operation knob of the modified example of this embodiment includes a spindle support member 2, an operation member 3, a support plate 4, a first rotating plate 5, and a first member 53 placed on the coordinate input device TP. The supporting plate 4 protrudes toward the radially outer side of the spindle supporting member 2, a plurality of first magnets 8 are arranged in the circumferential direction of one surface, and are fixed to the spindle supporting member 2. The operating member 3 covers the support plate 4 and the spindle support member 2. The first rotating plate 5 is provided with a plurality of second magnets 9 in the circumferential direction of one surface of the first rotating plate 5 that overlap with the first magnet 8 up and down to generate attractive force to the first magnet 8, and are located on the supporting plate 4 The TP side of the coordinate input device. The first member 53 is a conductive member protruding from the first rotating plate 5 toward the coordinate input device TP.

Thereby, if there is no rotating operation R of the operating knob 1, the relative rotation position of the first rotating plate 5 and the supporting plate 4 is maintained by the attractive force of the first magnet 8 and the second magnet 9. By the rotating operation R of the operating knob 1, the operating member 3 rotates relative to the spindle supporting member 2. The second magnet 9 that generates gravitational force on the first magnet 8 at a position overlapping with the first magnet 8 moves up and down, and generates gravitational force on the next adjacent first magnet 8, thereby transmitting the accompanying operation to the operator operating the knob 1.
