Is formed.

(Assembly method)
Next, a method for assembling the input device having the above-described configuration will be described. The assembly of the input device can basically be performed simply by superimposing the constituent members upward in the order described above.

  First, the metal base 1 is positioned on a jig (not shown). The jig is provided with a positioning pin and a locking pin, and the positioning pin is inserted into the base positioning hole 1b and the locking pin is inserted into the through hole 1a. Thereby, the metal base 1 is positioned at an appropriate position with respect to the jig.

  Then, the printed circuit board 2 is disposed on the metal base 1. A Hall element 17 is mounted in advance on the printed board 2, the positioning piece 9 of the metal base 1 is inserted into the insertion hole 2 b, and the locking piece 11 is disposed in the first cutout portion 16. In addition, a positioning pin is inserted into the board positioning hole 2a of the printed circuit board 2, and a rotation stopping pin is inserted into the rotation stopping hole 2c. Thereby, the printed circuit board 2 is positioned at an appropriate position with respect to the jig and the metal base 1.

  Subsequently, the insulating sheet 3 is disposed on the printed board 2. A positioning piece 9 is inserted into the insertion hole 3b of the insulating sheet 3, a positioning pin is inserted into the plate positioning hole 3a, a rotation pin is inserted into the rotation hole 3c, and a hall element 17 is inserted into the escape hole 3d. By inserting the positioning pin into the positioning hole 3a, the insulating sheet 3 is positioned with respect to the jig, the metal base 1 and the printed circuit board 2, and the movable contact portion 18 can be accurately contacted and separated from each fixed contact portion 15. Opposite to.

  Further, the push button 4 is disposed on the insulating sheet 3. The push button 4 is positioned in the rotational direction by slidingly engaging the rotation stop pin with the guide slit 22. In addition, the push button 4 prevents the guide projection 23 from being removed by causing the positioning piece 9 to be elastically deformed on both sides to be positioned in the guide hole 10 and restoring the shape of the positioning piece 9. In this state, the surface of the insulating sheet 3 bulged by the movable contact portion 18 is pressed against the lower surface of the push button 4 at the center of the insulating sheet 3. Accordingly, the push button 4 is positioned at the protruding position in a state where the guide protrusion 23 abuts on the inner edge of the upper end of the guide hole 10 and can be pushed. The metal base 1, the printed circuit board 2, and the insulating sheet 3 may be integrated by adhesion or the like so as not to be misaligned even after being removed from the jig. Thereby, the assembly of the lower half part comprised by each component shown in FIG. 7 is completed.

  On the other hand, the annular magnet 7 is fixed to the outer annular groove of the operation dial 8 (by double-sided tape, adhesive, etc.), and the operation plate 6 is disposed in the inner annular groove. Then, the caulking ring 5 is disposed on the lower surface of the operation dial 8, and the protrusion 28 a of the operation dial 8 is inserted into the caulking hole 24 of the caulking ring 5 and caulked. As a result, the operation plate 6 is held in a sandwich state between the operation dial 8 and the caulking ring 5, and the assembly of the upper half composed of the components shown in FIG. 6 is completed. In this state, the operation dial 8, the annular magnet 7, and the caulking ring 5 can rotate integrally with the operation plate 6.

  Finally, the upper half is assembled to the lower half. In this assembly, as shown in FIGS. 12A to 12C, the one leg portion 27 of the operation plate 6 is inserted into the opening portion 11a of the one locking piece 11 beyond the normal mounting position. Then, with the upper half inclined with respect to the lower half, the other leg 27 is elastically deformed as shown in FIG. 12 (d), and the other half is shown in FIG. 12 (e). Locks to the opening 11 a of the locking piece 11. Subsequently, the entire upper half is slid, and the locking claws 11b of the locking pieces 11 are locked in the rectangular holes 27a of the legs 27 as shown in FIG. Thereby, the assembly work is completed.

  As described above, the input device can simply complete the assembling work by simply assembling the respective constituent members sequentially with respect to the metal base 1. In particular, when assembling the upper half part to the lower half part, it is only necessary to lock the two parts as described above, so that the assembly workability is excellent.

  In the assembled state, the operation plate 6 receives the elastic force from the movable contact portion 18 of the insulating sheet 3 through the pressing protrusion 26 and pushes in as shown in FIG. It is biased in the direction opposite to the direction (separating direction). The leg portion 27 of the operation plate 6 abuts on the locking piece 11 formed on the metal base 1, and the locking claw 11b is locked in the rectangular hole 27a. Therefore, the operation plate 6 does not fall off in the separating direction depending on the bias of the movable contact portion 18. Moreover, as shown in FIG. 4A, the leg portion 27 of the operation plate 6 is always held in pressure contact with the inner edge of the locking piece 11 formed on the metal base 1. The leg 27 protrudes obliquely downward and is located in the opening 11a (in the horizontal portion), so that when the operation plate 6 is pushed through the operation dial 8, a clearance is provided as in the conventional case. The height dimension is suppressed. For example, in an input device having a diameter of about 20 mm, a height dimension of about 3 mm in the past can be set to about 2 mm in the present embodiment, and a reduction effect of 30% or more can be obtained.

(Operation)
Next, an operation in a state where the input device having the above configuration is incorporated in an electronic device (for example, a mobile phone) will be described.

  When the operation dial 8 is rotated by a finger or the like, the annular magnet 7 integrated by the crimping ring 5 is also rotated. A magnetic field that changes as the annular magnet 7 rotates is detected by the Hall element 17. A change in the magnetic field is output from the hall element 17 as an electric signal to a control unit (not shown) (provided in a mobile phone or the like on which an input device is mounted).

  The control unit detects the rotation direction and the rotation amount of the operation dial 8 based on the electric signal input from the hall element 17. Based on the detection result, for example, one of a plurality of items displayed on a monitor (not shown) is displayed so as to be distinguishable from the other (for example, highlighted display). If the desired item is displayed so as to be distinguishable from the others and the rotation of the operation dial 8 is stopped, the selected item is executed based on the pushing operation of the push button 4. Specifically, it is possible to display a list of names registered in the telephone directory and select the name by making an operation with the operation dial 8 to make a call. It is also possible to display a list of any hierarchy of data in a tree structure by pressing the operation dial 8 to turn on any of the four fixed contact portions 15 in the surrounding area. is there. Specifically, the name displayed as a list in the phone book can be used, for example, when the display is switched from “A” to “K”.
