Description

  The present invention relates to a composite operation type input device having a dial to be rotated and a push button located in a central opening of the dial.

  FIG. 11 shows a configuration described in Patent Document 1 as a conventional example of a composite operation type input device. In this example, the composite operation type input device includes a base 11 on which a predetermined electrode pattern and a fixed contact are formed, a movable contact 12, a presser sheet 13, a pusher 14, a contact member 15, and a tactile spring (FIG. 11). In this case, the rotating member 16, the cover 17, the button 18, and the operation member 19 are included.

  A cylindrical shaft portion 11a protrudes from the center of the base 11, and a rotating body 16 is attached around the shaft portion 11a. A contact member 15 is attached to the lower surface of the rotating body 16. The base 11 is covered with a cover 17 from above, and the rotating body 16 is prevented from coming off by the cover 17. The cylindrical portion 16 a of the rotating body 16 is located in the opening 17 a of the cover 17.

  The button 18 is inserted into the cylindrical portion 16 a of the rotating body 16 protruding from the opening 17 a of the cover 17, and the operation member 19 is attached to and integrated with the rotating body 16. On the movable contact 12 of the central switch 21, the button 18 is positioned at the opening 19 a of the operation member 19 with the large diameter portion 18 a being prevented from being detached by the operation member 19, and the pressing protrusion 18 b is formed on the inner bottom surface of the base 11. The presser sheet 13 is contacted. The central switch 21 includes a movable contact 12 and fixed contacts 21 a and 21 b formed on the inner bottom surface of the base 11.

  The slider (not visible in FIG. 11) of the contact member 15 is in contact with the rotary encoder contact 22 formed on the inner bottom surface of the base 11. A rotary encoder is configured.

  Peripheral switches 23 are configured at four locations around the inner bottom surface of the base 11. The peripheral switch 23 is configured by the movable contact 12 and fixed contacts 23a and 23b (23b is hidden and cannot be seen) formed on the inner bottom surface of the base 11 like the central switch 21. The pusher 14 is positioned on the peripheral switch 23, and the outer peripheral side of the flange portion 16 b of the rotating body 16 is positioned on the step portion 14 a of the pusher 14.

  In this composite operation type input device, when the operation member 19 is rotated, the rotating body 16 to which the contact member 15 is attached rotates integrally, and the slider moves on the rotary encoder contact 22. The rotation of the operation member 19 is detected by electrically detecting this movement.

  When the button 18 is pushed in, the movable contact 12 of the central switch 21 is pressed by the pressing projection 18b, and the central switch 21 is turned on. When the pressing is released, the button 18 returns to the original position by the restoring force of the movable contact 12, and the central switch 21 is turned off.

  On the other hand, by pushing the operating member 19 and tilting it, the peripheral switch 23 on the tilting side can be operated. As the operating member 19 is tilted, the rotating body 16 is tilted integrally with the operating member 19, whereby the movable contact 12 of the peripheral switch 23 is pressed via the pusher 14 and the peripheral switch 23 is turned on. When the pressure on the operation member 19 is released, the pusher 14, the rotating body 16, and the operation member 19 are returned to their original positions by the restoring force of the movable contact 12, and the peripheral switch 23 is turned off.

  In addition, the tilting operation of the operation member 19 is caused by the fact that the diameter of the opening 16c of the rotating body 16 facing the peripheral surface of the shaft portion 11a of the base 11 is gradually increased upward, and the flange of the rotating body 16 This is possible because a wedge-shaped space is secured between the portion 16 b and the cover 17.

  However, in this example, the dial base 41 has a structure in which the upper surface of the annular portion 41b is in sliding contact with the protrusion 39d provided on the lower surface of the annular projecting portion 39b of the base 39, that is, FIGS. It has a sliding contact portion a surrounded by a broken line.

  Since this sliding contact portion a is provided in a direction orthogonal to the foreign substance intrusion direction, foreign matters are less likely to enter the sliding contact portion a. Therefore, due to the presence of such a sliding contact portion a, In this example, foreign matter is unlikely to enter the sliding contact portion where the contact 38a is in sliding contact with the electrode pattern 33e.

  Next, the configuration of Embodiment 2 of the composite operation type input device according to the present invention will be described.

  In the first embodiment, the dial is vertically divided into two parts on the peripheral wall portion, and is composed of two parts, the dial top 42 and the dial base 41. In the second embodiment, the dial is composed of one part. FIG. 7 shows the configuration of the second embodiment. In FIG. 7, reference numeral 40 denotes a dial. In addition, the same code | symbol is attached | subjected to the part corresponding to the structure of Example 1. FIG.

  In this example, in order to facilitate the work of attaching the spring 51 to the upper surface of the annular portion 41b of the dial 40, it is necessary to prevent the operation portion 42c of the dial 40 from protruding from the inner periphery of the peripheral wall portion 42a as shown in FIG. In this respect, the area of the operation unit 42c is smaller than that of the first embodiment.

  Although such a configuration can be adopted depending on the application, in order to reduce the overall size of the composite operation type input device while ensuring a large area of the dial operation unit, two dials are used as in the first embodiment. It is preferable to configure with parts.

  Next, the configuration of Embodiment 3 of the composite operation type input device according to the present invention will be described.

  FIG. 8 shows the appearance, and FIG. 9 shows the cross-sectional structure. Parts corresponding to those in the first embodiment are denoted by the same reference numerals.

  In this example, the push button 53 ′ is replaced with a small-diameter flange portion 53b, and a large-diameter annular flat plate portion 53g facing the inner surface of the operation portion 42c of the dial top 42 ′ is integrally formed. The protrusions 42g and 53h that form a ring on 53g are formed in a staggered manner. The protrusions 42g and 53h are concentric circles, and two are formed in this example.

  By providing such protrusions 42g and 53h, the entry path of foreign matter entering from the gap between the dial top 42 'and the push button 53' can be made extremely long, so that the dial base 41 'and further Foreign matter reaching the sliding contact portion can be greatly reduced.

  On the other hand, the pusher 37 ′ has a shape as shown in FIG. 10 in this example, and includes an annular fixing portion 37′e and four protrusions formed on the outer periphery of the annular fixing portion 37′e at intervals of 90 °. The support portion 37′f and four pressing portions 37′c supported by the adjacent support portions 37′f via elastically deformable beams 37′b. Grooves 37'g are formed on the entire upper surface of the annular fixing portion 37'e, and four bosses 37'd are formed on the lower surface so as to protrude in the circumferential direction.

  As shown in FIG. 9, the annular fixing portion 37 ′ e is arranged on the circumference between the peripheral switch 62 and the electrode pattern forming the contact for the rotary encoder of the flexible printed wiring board 33, and the cover sheet is covered by the double-sided tape 54. It is adhesively fixed on 36. Each pressing portion 37 ′ c is positioned on the peripheral switch 62.

  The peripheral wall portion 41c of the dial base 41 'has a smaller diameter than the peripheral wall portion 42a of the dial top 42, and an annular protrusion 41i that enters the groove 37'g of the annular fixing portion 37'e of the pusher 37' is formed on the flange portion 41d. ing. The annular pressing portion 41e located on the pressing portion 37′c of the pusher 37 ′ is formed in a step portion 41j provided one step down on the outer periphery of the flange portion 41d, and a peripheral wall 41k is formed on the outer periphery of the step portion 41j. Projecting downward.

  Foreign matter is particularly likely to enter from the gap between the dial top 42 ′ and the push button 53 ′, and intrusion from the portion accommodated in the housing of the device in the composite operation type input device is generally small. However, in this example, the shape of the pusher 37 ′ and the dial base 41 ′ as described above is adopted, and the annular fixing portion 37′e of the pusher 37 ′ is adhesively fixed on the cover sheet 36, thereby providing a composite operation type input. Intrusion of foreign matter from the side of the device can be reduced, and in this respect, a composite operation type input device with higher reliability can be obtained.

  Although various embodiments of the present invention have been described above, a configuration in which there is no peripheral switch operated by a tilting operation of a dial (dial top) may be employed.

  Although the base 39 includes one annular protrusion 39d on the lower surface of the annular protrusion 39b, a plurality of protrusions 39d may be provided, or the protrusion 39d may be omitted. However, it is preferable to provide the protrusion 39d in order to reduce the sliding resistance of the sliding contact portion a.
