  FIG. 3 is a perspective view showing a state in which the button key of the scroll switch device for a mobile phone according to the first embodiment of the present invention is removed, and FIG. 4 is a mobile phone according to the first embodiment of the present invention. It is a perspective view which shows an example of the button key used for the scroll switch apparatus for telephones.

  FIG. 5 is a circuit diagram of a scroll switch device for a mobile phone according to a first embodiment of the present invention.

  FIG. 6 is a diagram in which a mobile phone scroll switch device according to a first embodiment of the present invention is arranged in a mobile phone. FIG. 7 is an enlarged view showing an information display portion and a scroll switch device portion of the mobile phone shown in FIG.

  A scroll switch device 1 for a mobile phone according to a first embodiment of the present invention is provided on a substrate 10, has a dome shape, and is turned on / off according to a dent deformation caused by pressing from above, The confirmation switch 2 configured to confirm the operation instruction to the mobile phone 21 shown in FIG. 6 is provided.

  Similarly, it has a dome shape and is turned on / off in accordance with the dent deformation by pressing from above, and is arranged around the confirmation switch 2 at a regular interval around the confirmation switch 2 in a cross shape. As shown in FIG. 7, first to fourth four selection switches 3 each configured to move the cursor 23 in a specific direction on the information display unit 22 of the mobile phone 21 are provided. It has.

  Here, the confirmation switch 2 is turned on when it is pressed with a force that substantially exceeds the force for turning on the selection switch 3.

  The main body portion 11 is integrally formed of a mold and rubber, and a rubber support member 12 is used to prevent rotation and position. The peripheral portion of the main body portion 11 is placed on the four dome type selection switches 3. A contact piece 13 is provided at a portion positioned and facing the selection switch 3, and a disk-shaped button key 5 having a convex portion 4 provided at a central portion facing the dome-shaped determination switch 2 is provided.

  The main body 11 of the button key 5 may be a mold and a rubber stick. And the button key 5 is installed in the case part 14 of the mobile telephone 21 arrange | positioned so that the main-body part 11 may be exposed.

  At this time, by pressing down the peripheral part of the button key 5, one selection switch 3 is selected from the four selection switches 3 and pressed, and the cursor 23 to the desired operation instruction display on the information display unit 22 is displayed. The configuration is to be set.

  In addition, the center portion of the button key 5 is pressed to operate the confirmation switch 2, the operation instruction for the operation instruction display set by the cursor 23 is confirmed, and the operation instruction is given to the mobile phone 21.

  Next, the operation of the scroll switch device for a mobile phone according to the first embodiment of the present invention will be described.

  First, the peripheral part of the button key 5 of the scroll switch device 1 for a mobile phone according to the first embodiment of the present invention is pushed by, for example, the + Y direction in FIG.

  The button key 5 is pushed down in a circular arc with the convex portion 4 as a fulcrum, and the first selection switch 3a having a dome shape is depressed and deformed by the pressing of the contact piece 13, and an on state is formed. At this time, the dome-shaped determination switch 2 that supports the convex portion 4 serving as a fulcrum has a strength that can withstand the force for pushing down the peripheral portion and deforming the selection switch 3, and is normally formed. The off-state being released is not released and the on-state is never turned on.

  Further, if the pressed position of the fingertip is moved in the + X direction while maintaining the depressed state, the second selection switch 3b adjacent to the contact piece 13 and the first selection switch 3a is also deformed, and the first and Two of the second selection switches 3a and 3b are simultaneously turned on.

  Further, when the pressing position is moved as it is by the fingertip, the dent deformation is eliminated in the first selection switch 3a, an off state is formed, and only the second selection switch 3b is turned on.

  Similarly, when the pressing position is moved while the peripheral portion of the button key 5 is pressed down, the switch changes from one circuit to two circuits and then again from one circuit.

  Further, when the button key 5 is sequentially depressed at about 12 o'clock (+ Y direction), 3 o'clock (+ X direction), 6 o'clock (−Y direction), and 9 o'clock (−X direction), the selection switch 3 of one circuit is turned on. When the switch is turned on and approximately 1:30, 4:30, 7:30, and 10:30 are sequentially depressed, the two-circuit selection switch 3 is turned on. At this time, the confirmation switch 2 is not turned on for the reason described above.

  Further, the center part of the button key 5 is pressed with a stronger force than the operation of the peripheral part to turn on the selection switch 3, and the dome-shaped confirmation switch 2 is turned on.

  From the above, it is possible to turn on one confirmation switch and four selection switches 3 that are independent of one simple button, and two adjacent combinations having four combinations by selecting the pressing position of the peripheral portion. The ON state of the selection switch can be formed.

  Next, the operation of the mobile phone using the mobile phone scroll switch device 1 according to the first embodiment of the present invention will be described.

  FIG. 8 is a diagram showing a system configuration of a main part of a mobile phone provided with a scroll switch device for a mobile phone according to the first embodiment of the present invention.

  The menu item is called by operating the button key 5 shown in FIGS. 6 and 7, and the information display drive circuit 27 is operated via the interface 25 in response to an instruction from the CPU 26 of FIG. 8, and the menu screen is displayed on the information display 22. Is done.

  At this time, the 12 o'clock direction or 6 o'clock direction of the button key 5 is pushed down, and the first and third selection switches 3a and 3c are operated. In accordance with the ON operation of the selection switches 3a and 3c, an instruction from the CPU 26 is made through the interface 25, the cursor 23 is moved on the menu screen on the information display unit 22, and the cursor 23 is displayed on an appropriate operation instruction display in the menu item. Are combined.

  Further, when the 3 o'clock direction or 9 o'clock direction of the button key 5 is depressed, the second and fourth selection switches 3b and 3d are operated, and the cursor 23 is similarly moved again on the menu screen, so that an appropriate operation instruction display is displayed. The cursor 23 is set to a specific item.

  At this time, by pushing down the 1:30 direction, 4:30, 7:30, or 10:30 direction of the button key 5, in addition to the movement of the up / down / left / right cursor 23, the button key 5 The cursor 23 can be moved.

  Finally, the confirmation switch 2 is turned on by pressing the center portion of the button key 5 with the cursor 23 set to an appropriate specific item. Then, the CPU 26 is informed of the ON state of the confirmation switch 2 via the interface 25. Subsequently, the CPU 26 instructs the confirmation circuit 28 via the interface 25, and the specific item of the operation instruction display on which the cursor 23 is set is confirmed. Determined by circuit 28.

  Therefore, in the mobile phone 21, an operation selected and confirmed by the scroll switch device 1 is performed on the information display unit 22.

  The following are modifications of the scroll switch device for a mobile phone which is the first embodiment of the present invention. Next, it demonstrates using drawing.
