[overall structure]
FIG. 1 is a block diagram showing a configuration of an electronic apparatus according to an embodiment of the present invention. An appearance of the electronic device 1 is shown in FIG. The electronic device 1 is configured as a small touch input device, and is mounted on, for example, a touch input portion of a laptop PC. Preferably, the electronic device 1 is mounted on a steering portion of a vehicle and used as an input device that a driver operates while viewing an operation image displayed on a display of a navigation device or a head-up display as a display unit. You can also.

  Specifically, the electronic device 1 includes a control unit 20, a driving device 30, and a touch pad (contact surface) 50. The electronic device 1 is connected to the display unit 5. The control unit 20 outputs and displays an operation image including, for example, an icon as a selected item in the operation input on the external display unit 5. Thereby, the user can see an operation image including an icon or the like.

  As the touch pad 50, a known electrostatic type or pressure sensitive type can be used. The touch pad 50 detects the coordinates of the position where the user has touched the contact surface with a contact body such as a finger, and supplies the position coordinates to the control unit 20.

  The drive device 30 includes a mechanism that moves the touch pad 50 in a direction along the contact surface. A specific structure of the drive device 30 will be described later.

  The control unit 20 outputs the operation image data to the external display unit 5 to display the operation image, acquires the contact position of the contact body from the touch pad 50, and recognizes the user input to the touch pad 50. The control unit 20 displays a cursor indicating the contact position on the operation image displayed on the display unit 5 based on the contact position acquired from the touch pad 50.

  Further, the control unit 20 analyzes the moving direction, moving amount, and the like of the contact position based on the contact position acquired from the touch pad 50. Then, the control unit 20 controls the drive device 30 to move the touch pad 50 based on the contact position of the contact body, the moving direction and moving amount of the contact position, and the like. Thereby, when the user is performing an input operation with a finger, the touch pad 50 moves as necessary. The movement of the touch pad 50 by the driving device 30 will be described later.

[Driver]
Next, the structure of the drive device 30 will be described. FIG. 3A is a perspective view showing the appearance of the electronic apparatus 1. In FIG. 3A, a part of the internal structure is shown with the touch pad 50 being transparent. The driving device 30 is provided inside the housing 31 of the electronic device 1.

  FIG. 3B shows a state where the upper cover of the casing 31 of the electronic device 1 is removed. A touch pad (contact surface) 50 is provided below the upper cover of the housing 31.

  FIG. 4A shows the electronic device 1 in a state where the touch pad 50 is further removed, and the internal structure constituting the driving device 30 is shown. A pair of support members 32 a and 32 b that support the touch pad 50 from below are provided below the touch pad 50.

  FIG. 4B is an enlarged view of a portion of the support member 32a. The support member 32a is fitted to a rotary shaft 36a on which a feed screw 36x is formed. That is, the rotation shaft 36a is inserted into a hole provided in the lower end portion of the support member 32a. The rotating shaft 36 a is integrated with a circular rotating body 35, and the rotating body 35 is connected to the motor 33 via a belt 34. The rotation of the motor 33 is transmitted to the rotating body 35 through the belt 34, and the rotating shaft 36a integrated with the rotating body 35 is rotated. Since the feed screw 36x is formed at the tip of the rotating shaft 36a, when the rotating shaft 36a rotates, the support member 32a moves in the moving direction 90 indicated by the arrow. That is, the support member 32a moves in a direction corresponding to the rotation direction of the rotation shaft 36a by a distance corresponding to the rotation amount of the rotation shaft 36a. A pressure sensor 32x is provided on the upper surface of the support member 32a.

  Fig.5 (a) is the perspective view which looked at the part of the supporting member 32a from diagonally downward. The illustration of the motor 33 is omitted. A fitting member 37 fitted to the feed screw 36x of the rotating shaft 36a is connected to the support member 32a. The rotation of the rotation shaft 36 a moves the fitting member 37 in the movement direction 90, and accordingly the support member 32 a also moves in the movement direction 90.

  FIG. 5B shows a state in which the fitting member 37 is removed from the support member 32a. A spring member 38 is attached to the support member 32a. When the fitting member 37 is connected to the support member 32a, the fitting member 37 is urged by the spring member 38 in the direction of the rotation shaft 36a. Due to the urging force of the spring member 38, the fitting between the fitting member 37 and the feed screw 36x of the rotary shaft 36a is ensured.

  FIG.5 (c) is the perspective view which looked at the part of the supporting member 32a from diagonally upward. As described above, the pressure sensor 32x is provided on the upper surface of the support member 32a. The pressure sensor 32x detects a pressing force by a contact body such as a user's finger. For example, when the pressure sensor 32x detects a pressing force equal to or greater than a predetermined value, the control unit 20 can determine that this is an icon selection decision.

  FIG. 6A is a perspective view of the motor 33 viewed from the belt 34 side. A spring member 39 is provided at the end of the rotating shaft 36 a on the rotating body 35 side, that is, outside the rotating body 35. The spring member 39 urges the rotating shaft 36a toward the end where the feed screw 36x is formed. This biasing force prevents the rotation shaft 36a from rattling.

  Returning to FIG. 4A, the support member 32b is configured to be movable in the movement direction 90 on the shaft 36b. Although the rotational force of the motor 33 is not applied to the support member 32b, the touch pad 50 is moved by the movement of the support member 32a, and accordingly, the support member 32b is moved in the movement direction 90 on the shaft 36b.

  Thus, the support members 32 a and 32 b and the touch pad 50 are moved in the movement direction 90 by the rotation of the motor 33. The control unit 20 controls the motor 33 by giving a signal indicating the rotation direction and the rotation amount to the motor 33.

  FIG. 6B shows an application example of the driving device 30. This application example is a configuration for initializing the position of the touch pad 50. Specifically, the magnet 41 is attached to the rotating shaft of the motor 33. A sensor 42 that detects the magnetic pole of the magnet 41 is provided in the vicinity of the magnet 41. The sensor 42 detects the magnetic pole of the magnet 41 and sends it to the control unit 20. The control unit 20 calculates the number of rotations of the motor 33, that is, how many times the motor 33 has rotated, based on the number of magnetic pole detections.

  In the initial state of the touch pad 50, it is desirable that the touch pad 50 is in the center of the movement direction 90, that is, in a state where it can move by the same amount in any direction. Therefore, as initialization, the control unit 20 rotates the motor 33 in one direction (for example, clockwise rotation) until the support member 32a reaches the movement limit position, and then the support member 32a reaches the reverse movement limit position. The motor 33 is rotated in the reverse direction (for example, counterclockwise). The control unit 20 calculates the number of rotations of the motor 33 during this period, thereby calculating the number of rotations of the motor 33 (referred to as “movable number of rotations”) corresponding to the movable range of the support member 32a. Then, the control unit 20 rotates the position of the support member 32a, that is, the touch pad 50, from the state where the support member 32a is located at any end along the rotation shaft 32a by a half of the movable rotation number. The initial position. The control unit 20 initializes the touch pad 50 when the electronic device 1 is powered on, for example.

[Touchpad movement control]
Next, movement control of the touch pad 50 will be described. The touch pad 50 detects the position of a contact body such as a user's finger on the touch pad 50 and transmits it to the control unit 20. The control unit 20 detects the movement of the contact position of the contact body, and performs an operation by the contact body based on the contact position, the movement direction and the movement amount of the contact position (hereinafter collectively referred to as “position information”). The touch pad 50 is moved by controlling the driving device 30 inside. Hereinafter, a specific moving method will be described.

(First movement method)
FIGS. 7A to 7C are diagrams illustrating a first moving method of the touch pad 50. FIG. In each figure, the left side shows an operation image displayed on the display unit 5, and the right side shows an operation state of the touch pad 50 by the finger 60. In the operation image displayed on the display unit 5, a cursor 51 is displayed at a position corresponding to the finger 60 that is a contact body. An icon 7 is displayed as a selection selected by the user.

  In the first moving method, the user moves his / her finger on the touch pad 50 and moves the touch pad 50 slightly when the cursor 51 reaches the position of the icon 7. First, as illustrated in FIG. 7A, when the position of the cursor 51 corresponding to the finger 60 is away from the icon 7, the touch pad 50 is stationary. Thereafter, as shown in FIG. 7B, when the user moves the finger 60 upward, the cursor 51 approaches the icon 7 accordingly, but the touch pad 50 is still still. Then, when the user moves the finger 60 further upward and the cursor 51 enters the area of the icon 7 as shown in FIG. 7C, the control unit 20 controls the drive device 30 to display the touch pad 50. Move it slightly down in the middle. Thereby, it can be notified to the user that the cursor 51 has reached the position of the icon 7, that is, the icon 7 has been selected.

  In the above example, since the user has moved the finger 60 upward, the touch pad 50 moves slightly downward at the position of the icon 7. On the contrary, when the user moves the finger 60 downward to reach the position of the icon 7, the touch pad 50 moves slightly upward.

  In addition, in the selection state of the icon 7, the user can determine (confirm) the selection of the icon 7 by further pressing the touch pad 50 with the finger 60 at the position. Specifically, when the pressure sensor 32x provided under the touch pad 50 detects a pressing force equal to or greater than a predetermined value, the pressure sensor 32x sends a detection signal to the control unit 20, and the control unit 20 displays the icon 7 at the current cursor 51 position. Determine (confirm) the selection.

  In the first movement method, the direction in which the touch pad 50 is moved is the direction in which the cursor 51 has moved before reaching the icon 7, that is, the direction opposite to the direction in which the finger 60 has moved. As a result, when the user moves the finger 60 in one direction, the touch pad 50 slightly moves in the opposite direction at a certain place, so that the user can stop further movement of the finger 60. Can sensuously know that the position where the icon 7 is selected is reached. This method is particularly effective in a situation where the user cannot keep staring at the display unit 5 during operation, such as when the electronic device 1 is mounted on the steering of the vehicle.

  In the first moving method, the amount by which the touch pad 50 is moved is a predetermined amount. Since the purpose is to inform the user that the position of the icon 7 has been reached, the amount of movement may be small. Further, considering that the user subsequently performs pressing for determining the selection of the icon 7, the movement amount in the first movement method is equal to or less than the width of the currently selected icon 7, or the average width of the icon 7. The following is recommended. That is, it is preferable that the amount of movement of the touch pad 50 by the first movement method be a small amount such that the cursor 51 is still located within the range of the icon 7 even after the movement.

(Second movement method)
FIGS. 8A to 8C are diagrams illustrating a second moving method of the touch pad 50. FIG. In each figure, the left side shows an operation image displayed on the display unit 5, and the right side shows an operation state of the touch pad 50 by the finger 60. In the operation image displayed on the display unit 5, a cursor 51 is displayed at a position corresponding to the finger 60 that is a contact body. An icon 7 is displayed as a selection selected by the user.

  The second movement method is such that the cursor 51 moves to the vicinity of the icon 7 as the user's finger 60 moves, and the cursor 51 enters the area of the icon 7 when reaching the peripheral area of the icon 7. The touch pad 50 is moved. First, as illustrated in FIG. 8A, when the position of the cursor 51 corresponding to the finger 60 is away from the icon 7, the touch pad 50 is stationary. Thereafter, as shown in FIG. 8B, when the user moves the finger 60 upward, the cursor 51 approaches the icon 7 accordingly, but the touch pad 50 is still still. Then, when the user moves the finger 60 further upward and the cursor 51 enters the predetermined peripheral area 8 of the icon 7 as shown in FIG. 8C, the control unit 20 controls the driving device 30. The touch pad 50 is moved upward in the drawing until the position of the cursor 51 enters the area of the icon 7. Thereby, when the cursor 51 moves to the peripheral area 8 of the icon 7, the cursor 51 can be drawn into the area of the icon 7.

  The peripheral area 8 of the icon 7 is determined in advance. For example, an area of a predetermined distance may be provided outside each icon 7. Moreover, you may decide for every icon and every kind of icon.

  The moving amount of the touch pad 50 is determined by the control unit 20 based on the position of the cursor 51 and the area of the icon 7. For example, the control unit 20 may calculate the distance between the current position of the cursor 51 and the center position of the target icon 7 and move the cursor 51 by that distance. In this case, the cursor 51 is always drawn to the center position of the target icon 7.

  The moving direction of the touch pad 50 is determined by the positional relationship between the cursor 51 and the icon 7 when the cursor 51 enters the peripheral area 8 of the icon 7. In the above example, since the user moves the finger 60 upward and the cursor 51 enters the peripheral area 8 of the icon 7, the cursor 51 is still below the icon 7 at that time. Therefore, the control unit 20 moves the touch pad 50 upward until the cursor 51 enters the area of the icon 7. On the other hand, when the user moves the finger 60 downward and the cursor 51 reaches the peripheral area of the icon 7, the cursor 51 is still above the icon 7 at that time. The touch pad 50 is moved downward until the area of the icon 7 is entered.

  This method is also particularly effective in a situation where the user cannot keep staring at the display unit 5 during operation, such as when the electronic device 1 is mounted on a vehicle steering. When the user moves the cursor 51 to the periphery of the desired icon 7, the touch pad 50 moves to pull the cursor 51 to the position of the icon 7. That is, the movement of the touch pad 50 assists the user in selecting the icon 7. Therefore, the user does not need to move the finger 60 while staring at the display unit 5 until the cursor 51 enters the region of the icon 7 accurately.

(Third moving method)
FIGS. 9A to 9C are diagrams illustrating a third movement method of the touch pad 50. FIG. In each figure, the left side shows an operation image displayed on the display unit 5, and the right side shows an operation state of the touch pad 50 by the finger 60. In the operation image displayed on the display unit 5, a cursor 51 is displayed at a position corresponding to the finger 60 that is a contact body.

  The third movement method is a method of continuously scrolling the operation screen. Normally, when the operation screen is continuously scrolled using the touch pad, the user needs to move the finger repeatedly by releasing the finger from the touch pad. For example, when scrolling the operation screen downward, the user touches the finger pad near the lower end of the touch pad and moves it to near the upper end of the touch pad, and then lifts the finger once away from the touch pad and again lowers the touch pad. This work is repeated by moving from near to the top. On the other hand, in the third moving method, when the finger 60 is released from the touch pad 50, the control unit 20 moves the touch pad 50 by a predetermined distance in the direction opposite to the moving direction of the finger 60. That is, the third moving method includes an operation of returning the touch pad 50 to the initial position when the user lifts his / her finger. Thus, even if the operation pattern is such that the position of the touch pad 50 gradually shifts, the pad automatically returns to the initial position while the user releases the finger. Even if it is limited, the user can repeat the same operation.

  Specifically, the user first brings the finger 60 into contact with the vicinity of the lower end of the touch pad 50 as shown in FIG. 9A, and then moves the finger 60 upward as shown in FIG. 9B. Along with this, the cursor 51 also moves upward. Here, when the finger 60 moves away from the touch pad 50, the control unit 20 moves the touch pad 50 downward by a predetermined distance d as shown in FIG. 9C. Preferably, the control unit 20 preferably returns the touch pad 50 to the initial position. Thereby, even if the user performs an operation pattern that gradually shifts the position of the touch pad 50 from the initial position, the touch pad 50 having a finite movable range can be used.

  Further, when the cursor reaches the vicinity of the boundary of the display area, in order to inform the user that “the cursor 51 cannot be moved any more”, the control unit 20 is caused to repeatedly move the touch pad 50 in the vertical direction to make small increments. You can make a simple move.

  In addition, when a map including a mountain is displayed in the display area of the display unit 5 and the cursor 51 is moved to get over the bumpy mountain, the amount of movement of the finger 60 before the cursor 51 gets over the mountain. Then, the movement of the touch pad 50 may be set slowly and shortly.

  Then, after the cursor 51 gets over the mountain, the movement of the touch pad 50 is set to be fast and long with respect to the movement amount of the finger. Further, at the position where the cursor 51 stops, the movement of the touch pad 50 is set to “fast” and “short” in the direction opposite to the movement amount of the finger 60. By performing such control, the control unit 20 gives a light sense of resistance to the user before the finger 60 goes over the mountain, gives the user a feeling that the finger 60 is taken over the mountain, and stops the cursor 51. In the position, the control unit 20 can stop the finger 60 naturally with a light click feeling to the user.

(Touchpad movement process)
Next, an example of touch pad movement processing by the above-described movement method will be described. FIG. 10 is a flowchart of the movement process of the touch pad 50. This process is executed by the control unit 20 shown in FIG. The control unit 20 may be configured by a computer, and the computer may execute a program prepared in advance to perform the following processing. Note that the movement process shown in FIG. 10 is for performing all of the first to third movement methods described above, but the application of the present invention is not limited to this, and the first to third movements are performed. Any one or two of the methods may be employed.

  First, the control unit 20 acquires the contact position of the contact body on the touch pad 50 from the touch pad 50, and determines whether or not the contact position has moved a predetermined distance d (step S11). When the contact position has moved by a predetermined distance d (step S11; Yes), the control unit 20 controls the driving device 30 to return the touch pad 50 by the distance d in the direction opposite to the moving direction of the contact position (step S12). This corresponds to the third movement method described above. On the other hand, when the contact position has not moved by the predetermined distance d (step S11; No), the process proceeds to step S13.

  Next, the control unit 20 determines whether or not the contact position is within the peripheral area of the icon (step S13). When the contact position is within the icon peripheral area (step S13; Yes), the control unit 20 controls the driving device 30 to move the touch pad 50 so that the contact position falls within the icon area ( Step S14). This corresponds to the second movement method described above. On the other hand, when the contact position does not enter the peripheral area of the icon (step S13; No), the process proceeds to step S15.

  Next, the control unit 20 determines whether or not the contact position is within the icon area (step S15). When the contact position is within the icon area (step S15; Yes), the control unit 20 controls the driving device 30 to move the touch pad 50 slightly in the direction opposite to the movement direction of the contact position so far. (Step SS16). This corresponds to the first moving method described above. Next, the control unit 20 determines whether or not the touch pad 50 has been pressed based on the output of the pressure sensor 52x below the touch pad 50 (step S17). This is a determination as to whether or not the user has made an input for determining (determining) the currently selected icon. If there is a push (step S17; Yes), the control unit 20 finalizes the selection of the icon by the user (step S18) and ends the process.

  On the other hand, when the contact position does not fall within the icon area (step S15; No) and when the touch pad 50 is not pressed (step S17; No), the process returns to step S11.

[Modification 1]
In the embodiment described above, the case where the icon 7 is selected using the cursor 51 has been described. On the other hand, as an electronic device that selects the icon 7 without using the cursor 51, for example, the user moves a finger on the touch pad 50 and moves the icon 7 to a predetermined position, thereby selecting the icon 7. And a display unit 5 such as a touch panel. In the display unit 5, the control unit 20 is set to select the icon 7 arranged at a predetermined position in the display area of the display unit 5. The present invention can be applied to the display unit 5 that does not use the cursor 51. The selected icon 7 changes a part of the image of the icon 7 in the state before being selected and displays a selection mark, thereby allowing the user to visually recognize that it is in the selected state. For example, when the icon 7 reaches a predetermined position on the display unit 5, the frame (eg, blue) of the icon 7 is changed to red, or the background color (eg, blue) of the icon 7 is changed to red. Can be mentioned. That is, the frame or background color of the icon 7 that has changed to red becomes the selection mark.

  In a personal computer or the like including the display unit 5 using the cursor 51, the icon 7 is selected as the selected item by moving the cursor to the icon 7. That is, the position to be selected is not determined in the display area of the display unit 51.

On the other hand, in the case of the display unit 5 that does not use the cursor 51, the position to be selected is predetermined in the display area of the display unit 5.
[Touchpad movement control]
The description which overlaps with the above-mentioned Example is abbreviate | omitted.

(First movement method)
In the first moving method according to the first modification, when the user moves his / her finger on the touch pad 50 to bring the position of the icon 7 displayed on the display unit to a predetermined position, the touch pad 50 is slightly moved. It is. Thereby, it can be notified to the user that the icon 7 has reached the home position, that is, the icon 7 has been selected.

(Second movement method)
In the second movement method, the icon 7 is moved to a fixed position when the position of the icon 7 displayed on the display unit reaches the peripheral area of the fixed position in accordance with the movement of the user's finger 60. The touch pad 50 is moved.

(Third moving method)
Similar to the above-described embodiment, in the third movement method, when the finger 60 is released from the touch pad 50, the control unit 20 returns the touch pad 50 to the initial position. As a result, even if the user's motion pattern is such that the position of the touch pad 50 gradually shifts from the initial position, the touch pad 50 is automatically initialized while the user releases the finger 60 from the touch pad 50. Since the position returns, the user can repeat the same operation even if the movable range of the touch pad 50 is limited.

[Modification 2]
In the above embodiment, the driving device 30 is movable in the vertical direction in the operation image. However, the present invention is not limited to this, and may be movable in the horizontal direction in the operation image. Further, the drive device 30 may have a structure in which the touch pad 50 can be moved in the biaxial direction, and may be moved in the biaxial direction of up, down, left and right.

  In the above embodiment, the user's finger is mainly cited as the contact body to the touch pad, but an object such as a touch pen or a stylus may be used as the contact body.
