Thus, the outer peripheral substrate electrodes 35A and 35B and the central substrate electrode 35C are integrated with the flexible printed wiring board 31 on which the magnetic field detection circuit 32 is disposed.

  The magnet 37 is a cylindrical magnet having a circular hole 37A in the center, and is magnetized, for example, with an N pole on the upper surface and an S pole on the lower surface so that a magnetic flux parallel to the side wall is generated.

  Next, the configuration of the input device 60 will be described.

  Here, the input device 60 includes a trackball 50, a pressure sensitive resistor 51, a movable electrode 52, a cover sheet 53, and a pressing body 54.

  The pressure sensitive resistor 51 is a sheet-like pressure sensitive resistor, and has fine irregularities 51A on the upper surface. The irregularities 51A face the outer peripheral substrate electrodes 35A and 35B and the central substrate electrode 35C.

  When the pressure-sensitive resistor 51 is pressed against the outer peripheral substrate electrodes 35A and 35B, the unevenness 51A is crushed and the contact area between the outer peripheral substrate electrodes 35A and 35B and the pressure-sensitive resistor 51 increases. Thereby, it is comprised so that the resistance value between outer periphery board | substrate electrode 35A, 35B may fall.

  The movable electrode 52 is a dome-shaped conductive metal plate protruding downward. The center of the movable electrode 52 is opposed to the central substrate electrode 35C via the pressure sensitive resistor 51, and the outer edge of the movable electrode 52 is an outer peripheral substrate. The pressure-sensitive resistor 51 is in contact below the electrodes 35A and 35B.

  The cover sheet 53 is a resinous sheet having an adhesive layer (not shown) on the upper surface, and the movable electrode 52 and the pressure sensitive resistor 51 are fixed to the electrode substrate portion 31C of the flexible printed wiring board 31 from below. is doing.

  The pressing body 54 is cylindrical and is formed of resin or the like. The pressing body 54 is disposed below the center of the movable electrode 52.

  The input device 60 configured in this way is arranged with the upper portion of the ball 41 exposed on the operation surface of an electronic device such as a mobile phone. Then, wiring is connected to the external connector 34 of the input device 60 from a circuit board (not shown) of the electronic device, and is connected to a device control circuit (not shown) such as a microcomputer of the electronic device.

  For example, the input device 60 is used when the pointer is moved in a state where a plurality of menu displays and a pointer for selecting one of the menu displays are displayed on a liquid crystal display (not shown) of the electronic device. .

  Here, for example, when the pointer is moved to the left, the ball 41 is rotated in the direction of the arrow C as shown in the sectional view of FIG. Then, the magnetic body 42 built in the ball 41 similarly moves in the direction of arrow C.

  Here, the magnetic field detection circuit 32 detects the amount of the magnetic flux generated by the magnet 37 and returning to the magnet 37 via the magnetic body 42 and passing through the magnetic field detection circuit 32.

  When the ball 41 rotates, the magnetic body 42 rotates, and the protrusion 42A rotates accordingly. The amount of magnetic flux passing through the protrusion 42A is slightly increased. When the ball 41 rotates, the amount of magnetic flux detected by the magnetic field detection circuit 32 changes. As a result, the output of the magnetic field detection circuit 32 changes, and the control circuit 33 connected to the magnetic field detection circuit 32 determines the rotation direction of the ball 41.

  That is, when the ball 41 is rotated, the magnetic field detection circuit 32 detects a change in magnetic flux caused by the rotation, and the control circuit 33 determines the rotation direction of the ball 41 from the output signal of the magnetic field detection circuit 32.

  That is, regardless of the direction in which the ball 41 is rotated, the control circuit 33 can determine the rotation direction. As a result, the operator can move the pointer displayed on the liquid crystal display of the electronic device in a desired direction.

  Next, the display on the liquid crystal display when the operator rotates while pressing the ball 41 will be described.

  Here, when the operator rotates while pressing the ball 41, the moving speed of the pointer changes at a speed reflecting the pressing force, and the operation can be performed at a high speed at a speed reflecting the operation intention of the operator.

  When the pointer is moved to a desired menu display and pressed with a strength exceeding a predetermined pressing force, the movable electrode 52 is reversed to generate a predetermined moderation feeling, and the selected menu display is confirmed. . Here, the operator feels moderation when the predetermined pressing force is exceeded, so that the input device 60 can be stably operated.

  Thus, the electrical change which arises when an operator presses the ball | bowl 41 is demonstrated using the circuit diagram of FIG. 5, and principal part sectional drawing of FIG.

  First, FIG. 5 is a circuit diagram of a main part related to pressing of the ball 41 in the input device 60. Here, the outer peripheral substrate electrode 35 </ b> A is connected to the power supply potential Vc of the electronic device via the external connector 34.

  In addition, the outer peripheral substrate electrode 35B is connected to the analog input terminal P1 of the control circuit 33, and is connected to the ground potential of the electronic device via the resistance element 71 having the resistance value R1 disposed on the flexible printed wiring board 31 and the external connector 34. Connected to V0.

  Further, the central substrate electrode 35C is connected to the digital input terminal P2 of the control circuit 33, and is connected to the ground potential of the electronic device via the resistance element 72 having the resistance value R1 disposed on the flexible printed wiring board 31 and the external connector 34. Connected to V0.

  The resistance value R1 is preferably 1 kΩ to 100 kΩ, and the resistance value R2 is preferably 1 Ω to 1 kΩ. Here, when selecting the resistance value R1 and the resistance value R2, the resistance value R1 is set larger than the resistance value R2.

  Further, the pressure-sensitive resistor 51 disposed on the outer peripheral substrate electrodes 35A and 35B and the central substrate electrode 35C has a variable resistance Rab between the outer peripheral substrate electrode 35A and the outer peripheral substrate electrode 35B, and the outer peripheral substrate electrode 35A and the central substrate electrode 35B. The space between the substrate electrodes 35C is equivalently shown as a variable resistance having a resistance value Rac.

  In addition, it is preferable to select the sheet resistance of the resistor constituting the pressure sensitive resistor 51 so that the resistance value Rab and the resistance value Rac are 1 kΩ to 100 kΩ in a state where the pressure sensitive resistor 51 is not pressed. Further, the resistance value Rac is set sufficiently larger than the resistance value R2, and the control circuit 33 determines that the potential of the central substrate electrode 35C is LO near the ground potential V0 in a state where the pressure sensitive resistor 51 is not pressed. To do.

  6 will be described with reference to FIG. 5. FIG. 6A is a cross-sectional view of the pressure-sensitive resistor 51 not being pressed, and FIG. 6B is a pressure-sensitive resistor. It is sectional drawing of the state by which the body 51 was pressed.

  When the pressure sensitive resistor 51 is not pressed, the analog input terminal P1 of the control circuit 33 has a resistance value Rab and a resistance value between the power supply potential Vc and the ground potential V0. The potential divided by R0 is input.

  Further, since the resistance value Rac is sufficiently larger than the resistance value R2, the potential of the digital input terminal P2 is a potential at which the control circuit 33 determines LO.

  At this time, the control circuit 33 sends an output signal reflecting the potential input to the analog input terminal P1 and the potential of the digital input terminal P2 to the device control circuit of the electronic device via the external connector 34. For example, the pointer displayed on the liquid crystal display is moved at the initial speed.

  On the other hand, in the state of FIG. 5B where the pressure sensitive resistor 51 is pressed, the resistance value Rab decreases and approaches zero, so that the potential input to the analog input terminal P1 of the control circuit 33 increases, and the power supply It becomes close to the potential Vc.

  Further, since the pressure-sensitive resistor 51 is not pressed below the central substrate electrode 35C, the resistance value Rac remains sufficiently larger than the resistance value R2. That is, the potential of the digital input terminal P2 is maintained at the potential determined by the control circuit 33 as LO.

  Here, the movable electrode 52 is disposed between the outer peripheral substrate electrodes 35A and 35B and the pressing body 54 so that a pressing force is applied from the trackball 50 on the outer peripheral substrate electrodes 35A and 35B side. With this configuration, the pressing force against the pressure-sensitive resistor 51 below the outer peripheral substrate electrodes 35A and 35B can be applied while suppressing partial bias, so that the input device 60 with high reproducibility of operation can be obtained. Realized.

  In addition, by providing the pressing body 54, the pressure-sensitive resistor 51 can be stably pressed even when the trackball 50 is pressed obliquely, for example.

  At this time, the control circuit 33 sends an output signal reflecting the potential input to the analog input terminal P1 and the potential of the digital input terminal P2 to the device control circuit of the electronic device via the external connector 34. Here, the device control circuit controls the moving speed of the pointer by the potential input to the analog input terminal P1, and moves the pointer at a speed reflecting the pressing force on the ball 41.

  Further, after the state of FIG. 6B, when the pressing force applied to the ball 41 by the operator exceeds a predetermined strength, the vicinity of the central portion of the movable electrode 52 is depressed with a sense of moderation, and the central portion of the movable electrode 52 is depressed. The vicinity presses the pressure-sensitive resistor 51 below the central substrate electrode 35C. Thereby, the resistance value Rac becomes close to zero, and the potential of the digital input terminal P2 changes to a potential determined by the control circuit 33 as HI.

  At this time, the control circuit 33 sends an output signal reflecting the potential of the digital input terminal P2 to the device control circuit of the electronic device via the external connector 34. Here, the device control circuit determines the menu display selected by the movement of the pointer.

However, the present invention is provided at least below one of the outer peripheral substrate electrodes 35A and 35B. Can be implemented.

  As described above, according to the present embodiment, when the direction input unit for detecting the operation direction of the trackball 50 or the like is pressed, the pressure-sensitive resistor 51 receives a pressing force, and the resistance of the pressure-sensitive resistor 51 is changed to the direction input unit. The input device 60 is configured so as to change in accordance with the pressing force, and an input device 60 capable of high-speed operation reflecting the pressing force can be obtained.

  In addition, the apparatus further includes a movable electrode 52 disposed below the pressure-sensitive resistor 51. When a predetermined pressing force is exceeded, the operator can feel a moderation so that a stable operation can be performed. Have
