  • the rotating operation member is typically a rotating tab (rotating knob) or a rotating dial.
  • the electronic device may have an outer surface member which includes an outer surface of the device, and hence the rotating operation member is located so that a step is formed for retracting the operation plane of the rotating operation member inwardly of the device from the outer surface of the device in the outer surface member.
  • the rotating operation member may have a leg portion extending toward the switch at a position deviated from the rotating shaft, so that the distal end of the leg portion presses the switch. In this configuration, even when the switch is apart from the outer surface of the device, the switching operation can be performed adequately.

  • Fig. 3 is a cross-sectional view showing an operating state of the electronic device.
  • Fig. 4 is an exploded perspective view of the electronic device when viewed from the back.
  • an electronic device 1 includes a front panel 3, a rotating operation member 5, a switch 7 and a substrate 9 on which the switch 7 is mounted. Not shown in the figure, the electronic device 1 has a housing for covering the entire device including the front panel 3.
  • the electronic device 1 further includes various configurations such as a power source. In order to explain the present invention understandably, a configuration shown in Fig. 1 will be mainly described. In the description shown below, a front side of the front panel 3 may be referred to as a front portion or a forward, and a back side of the front panel 3 is referred to as a rear portion or a rearward.
  • the front panel 3 is formed of resin, and corresponds to the outer surface member of the electronic device 1.
  • the front panel 3 is provided with a parallelepiped operation member mounting unit 31 projecting from the back surface thereof as shown in the figure.
  • the operation member mounting unit 31 is provided with an operation member storage section 32 for storing the rotating operation member 5.
  • the rotating operation member 5 is a rotating tab (knob).
  • the rotating tab is arranged so as not to project from the front panel 3 (outer surface member).
  • the operation plane of the rotating tab has a cylindrical surface, and is located at a position where the operation plane does not project from the front surface.
  • the rotating operation member 5 can also be referred to as a rotating dial.
  • the rotating operation member 5 is formed of resin and is a cylindrical member.
  • the rotating operation member 5 has schematically a shape of a half-cut cylinder.
  • an operation plane 51 is an outer peripheral surface of the cylinder, and is operated with a finger of the operator.
  • the operating member storage section 32 has a shape corresponding to the operation plane 51. Accordingly, the rotating operation member 5 is stored in the operating member storage section 32.
  • the rotating operation member 5 has side walls 52 on both sides of the operation plane 51. Rotating shafts 53 project respectively from the two side walls 52. The respective rotating shafts 53 are positioned at the substantially center of the cylindrical shape of the operation plane 51.
  • the front panel 3 has protruding portions 33 on both sides of the operating member storage section 32. The protruding portions 33 each are provided with a bearing 34.
  • the rotating shafts 53 of the rotating operation member 5 are fitted to the bearings 34. Accordingly, the rotating operation member 5 is rotatably supported by the rotating shafts 53. In this supporting structure, the rotating shafts 53 extend in parallel with the outer surface of the front panel 3.
  • the protruding portions 33 of the front panel 3 each include a notch 35 extending rearward from the bearing 34.
  • the notch 35 is used at the time of assembly. In other words, at the time of assembly, the rotating operation member 5 is inserted into the operating member storage section 32 from the back side of the front panel 3. At this time, the rotating shafts 53 are pressed against the notches 35 of the rotating operation member 5.
  • the front panel 3 is formed of resin, and is capable of deforming resiliently to some extent. Therefore, the notches 35 are widened by being pressed by the rotating shafts 53. Accordingly, the rotating shafts 53 can pass through the notches 35 and reach the bearings 34.
  • the front panel 3 has an operating window 36 on the basilar part of the operating member storage section 32.
  • the operating window 36 is an opening formed through the front panel 3.
  • the operation plane 51 of the rotating operation member 5 is exposed from the operating window 36.
  • the operation plane 52 has a recess 54 at a position corresponding to the operating window 36.
  • the recess 54 is provided so that the operator can hook his/her finger easily.
  • the rotating operation member 5 is provided with a leg portion 55 extending toward the inside of the device, as shown in the drawing.
  • the leg portion 55 is provided so as to extend from one end of the operation plane 51. Therefore, the leg portion 55 is at a position deviated from the rotating shaft 53.
  • a distal end of the leg portion 55 reaches the switch 7 mounted to the substrate 9.
  • the substrate 9 is provided with a printed circuit relating to the switch 7.
  • the substrate 9 is provided with various electronic parts mounted thereon.
  • the substrate 9 is mounted to the housing of the electronic device 1 (not shown) and is supported thereby.
  • the rotating operation member 5 is provided with stoppers 56, 57 at both ends of the operation plane 51.
  • the stoppers 56, 57 are projections provided on the operating plane 51.
  • the stoppers 56, 57 limit the rotating range of the rotating operation member 5 by bumping into the operating member mounting unit 31.
  • the stopper 56 one of the stoppers, is provided adjacent to the basilar part of the leg portion 55.
  • the stopper 56 limits the rotating range in the direction in which the leg portion 55 moves apart from the switch 7 (clockwise direction in the figure).
  • the rotating operation member 5 In a state in which the rotating operation member 5 is not operated, the rotating operation member 5 is urged clockwise by a spring (not shown), and then the stopper 56 is functioning.
  • the other stopper 57 is provided on the opposite side of the stopper 56. The stopper 57 limits the rotating range in the direction in which the leg portion 55 presses the switch 7 (counterclockwise direction in the figure). In Fig. 1 and others, for easy viewing, the stopper is illustrated at a position slightly apart from the operating member mounting unit.
  • the operation plane 51 of the rotating operation member 5 is rotated by the operator.
  • the operator's finger is hooked on the recess 54 on the operation plane 51, and is moved in the direction along the outer surface of the front panel 3 (in the vertical direction in the figure).
  • the rotating operation member 5 rotates about the operating shafts 53.
  • the distal end of the leg portion 55 of the rotating operation member 5 also rotates to press the switch 7.
  • the distal end of the leg portion 55 rotates about the rotating shaft 53, and hence moves obliquely with respect to the switch 7. With the oblique movement, the distal end of the leg portion 55 can press the switch 7.
  • the rotating operation member 51 is urged by the spring (not shown) and returns to the original position.
  • an external force which may cause the switch operation error is applied to the electronic device 1.
  • Such an external force acts generally on the outer surface of the front panel 3 vertically, that is, in the direction to press the rotating operation member 5.
  • the switch operating direction is changed from the uniaxial direction (direction to press the button down) in the related art to the rotating direction.
  • the operation plane 51 of the rotating operation member 5 is configured to move along the circular track. Then, the operation plane 51 moves along the outer surface in the vicinity of the outer surface of the front panel 3. Therefore, even when an external force in the direction at a right angle to the front panel 3 is applied, the switch is not operated. Accordingly, the operation error can be prevented.
  • the electronic device 1 in this embodiment is applied, for example, to a navigation device.
  • the navigation device of a hideaway type is installed at an unspecified position such as in the trunk room or under the seat. Therefore, it is possible that the rolling objects such as small articles roll to contact with the electronic device 1. In such a case, the external force by the contact of the object is applied in the vertical direction to the outer surface of the front panel 3.
  • the rotating operation member 5 since the rotating operation member 5 does not rotate with such an external force, the operation error can be prevented effectively.
  • the electronic device 1 in this embodiment is applied, for example to a steering wheel device.
  • the driver may press the switch of the steering wheel unintentionally.
  • the rotating operation member 5 cannot be rotated simply by being pressed by the driver, whereby the operation error can be prevented effectively.
  • the electronic device 1 in the first embodiment of the present invention includes the configuration in which the switch is pressed by the rotating operation member 5, the switching operation is a rotational movement along the circular track. Therefore, the operation error of the switch caused by the external force applied unintentionally will be prevented.
  • the prevention of the operation error is realized by the rotational supporting structure of the operating member, and hence the operation error can be prevented with a less number of components, and the material cost can also be reduced.
  • the rotating operation member 5 includes the leg portion 55 at a position deviated from the rotating shaft 53. Accordingly, even when the switch 7 is apart from the outer surface of the device, the switching operation can be performed adequately.
  • the electronic device 1 in this embodiment may be provided in the navigation device. Accordingly, even when it is installed at an unspecified position such as the trunk, the operation error due to the contact of the object such as small articles can be prevented.
  • the electronic device 1 in this embodiment may be provided on the steering wheel device. Accordingly, the operation error such that the driver erroneously presses a button or the like on the steering wheel can be prevented effectively.
  • the rotating operation member 5 is arranged so that the operation plane 51 of the rotating operation member 5 is located rearwardly of an outer surface (front surface) 37 of the front panel 3 as the outer surface member. Accordingly, a step X is formed so that the operation plane 51 is retracted from the outer surface 37.
  • the second embodiment in Fig. 5 is different in the following points from the first embodiment in Fig. 1.
  • the amount of protrusion of the operating member storage section 32 from the front panel 3 is increased. Therefore, the operating member storage section 32 and the bearings 34 are moved inwardly. Accordingly, the length from the outer surface of the front panel 3 to the bearing 34 becomes long. Therefore, the rotating operation member 5 is moved inwardly, thereby generating the step X.
  • the external force can hardly effect on the rotating operation member 5. Not only the external force in the direction vertical to the front panel 3, but also the external force in the direction along the outer surface 37 of the front panel 3 can hardly effect thereon. Therefore, since the external force in the direction to rotate the rotating operation member 5 can hardly effect thereon as well, the operation error caused by such an external force can also be prevented.
  • the step structure is formed with the rotational structure of the operating member.
  • the rotational structure of the operating member prevents the operation error caused by the external force in the direction to press the switch downward.
  • the step structure can prevent the operation error caused by the external force in the direction to rotate the switch. In this manner, the operation error preventing capability can be improved.
  • the electronic device according to the present invention is provided with the operation error preventing function using the rotating operation member, whereby the effects such that the number of components can be reduced and the material cost can be reduced are achieved, so that it is effective in the vehicle-mounted device and the like.
