Definitions

  • the present invention relates to a multi-operational input device which is capable of carrying out a predetermined input operation with two different press and rotation operations, and more particularly, to a multi-operational input device which mounts a press detecting element and a rotation detecting element on a common circuit board.
  • a pair of plungers is slidably held in the operating body, respectively, through a coil spring, and front tips of these plungers protrude from an external edge of the operating body and engage with concavity and convexity formed at an inner peripheral surface of the case.
  • a shaft is provided in the center of the operating body, and a cylindrical portion is provided outside of the shaft.
  • the code plate is spline-connected to the shaft of the center through the return spring. Accordingly, even though the code plate rotates integrally with the operating body, the code plate does not move vertically while the operating body moves vertically.
  • the rotation detecting element is made up of photo interrupters that are mounted inside of the circuit board.
  • the press detecting element is made up of separate photo interrupters mounted outside of the circuit board, when the cylindrical portion moves down along with the pressing operation of the operating body, a light path of the photo interrupter is blocked so that an on-signal is output.
  • the code plate rotates integrally with the operating body. Therefore, on/off signals are alternately output from the photo interrupters (rotation detecting element) mounted inside on the circuit board, and the operator can detect rotation operation performed by the operator on the basis of these signals.
  • the photo interrupters rotation detecting element mounted inside on the circuit board
  • the operator can detect rotation operation performed by the operator on the basis of these signals.
  • a front end of a plunger is disengaged from the uneven portion of an inner peripheral surface of the case so as to generate a click feeling; therefore, the operator can perceive the rotation amount of the operating body by the click feeling.
  • the cylindrical portion blocks a light path of a separate photo interrupter (press detecting element) which is mounted outside of the circuit board when the operating body has moved by a predetermined stroke. Therefore, the output from the photo interrupter is converted from ON to OFF, and pressing of the operating body can be detected by the converted signals.
  • the code plate does not move while the operating body moves downward, signals from the photo interrupter (rotation detecting element) inside the circuit board are not converted.
  • the cylindrical portion is deviated from the light path of the outside photo interrupter (press detecting element). Accordingly, the output from the photo interrupter is converted from OFF to ON, and moving of the operating body can be detected on the basis of the converted signal.
  • the entire input device including the circuit board should be made large in a transverse direction; therefore, it is difficult to make the device small in the transverse direction.
  • the above-mentioned problem is not limited to an input device in which the photo interrupter is used both in the rotation detecting element and the press detecting element.
  • the problem is also found in an input device, in which a push switch is used as the press detecting element, and a photo interrupter is used as the rotation detecting element.
  • the front end of the plunger which protrudes from an outer edge of the operating body is pressure-contacted with the uneven portion of the inner peripheral surface of the case, and the rotation of the operating body makes the plunger disengaged from the uneven portion so as to generate a click feeling. Therefore, the input device is inevitably made large in the transverse direction by the aforementioned click mechanism, and thus it is difficult to make the device small in the transverse direction.
  • the present invention has been finalized in view of the inherent drawbacks in the related art, and it is an object of the present invention to provide a multi-operational input device which can be made small in the transverse direction.
  • a multi-operational input device includes a press operating member which is supported by a supporting body so as to be press-operated; a circuit board which is disposed in a press-operating direction of the press operating member; a press detecting element which is mounted on the front surface of the circuit board and operated by pressing the press operating member; a rotation operating member which is supported by the supporting body so as to be rotatably operated; and a rotation detecting element which is mounted on the circuit board and operated by rotating the rotating operating member.
  • the rotation detecting element is mounted on the rear surface of the circuit board, and a part of the rotation operating member is allocated at the front side of the circuit board, and a rotating force of the rotation operating member applied from the front side of the circuit board is transmitted to the rear side of the circuit board.
  • a mounting space of the press detecting elements overlaps with one side of the circuit board, and the rotation detecting elements overlaps with the other side of the circuit board. Accordingly, it is possible to make the entire input device small in a transverse direction.
  • the rotation operating member is preferably a barrel-shaped rotation ring which surrounds the circuit board. Accordingly, it is possible to make the multi-operational input device small in a lengthwise direction.
  • the supporting body includes an upper knob and a lower knob which hold the rotation ring therebetween, and the circuit board and the upper knob are fixed onto an upper end of a support shaft which is erected at the center of the lower knob. Accordingly, it is possible to improve operability by adjacently disposing the press knob and the rotation ring.
  • rotation detecting elements may be used, such as a hall element, a rotary encoder or he like.
  • the rotation detecting element includes photo interrupters, in which a light emitting element and a light receiving element are disposed to face each other with a concave portion interposed therebetween.
  • a code plate having the light shielding portion and the light transmitting portion is fixed onto an inner peripheral surface of the rotation ring, and the light shielding portion and the light transmitting portion move inside the concave portion in conjunction with the rotation of the rotation ring.
  • the click mechanism can be disposed in a space under the circuit board. Therefore, it is possible to make the entire input device small in the transverse direction by the click mechanism, and to prevent rattling of the rotation ring by using the urging force of the plunger provided in the click mechanism.

  • the front ends of the convex portions 11b-1 and 11b-2 slide on the facing inner wall surfaces of the aperture 18, and the convex portion 11b-3 intrudes into the notch portion 18a-3; therefore, the engaging protrusion 11 is prevented from moving in the Y1 direction more than a location where the outer wall surface of the engaging protrusion 11 located in the Y1 direction is in contact with the inner wall surface of the aperture 18.
  • the engaging protrusion 11 are restricted within the aperture 18 by three parts, that is, the convex portions 11b-1, 11b-2, and 11b-3; therefore, the operating body 2 moving in the Y1 direction is prevented from moving in either the X1 or X2 direction by mistakes.

  • the arm portion 19b is guided by the first guide protrusion 16b of the guide member 16, and the first slider 19 moves in the X1 direction; therefore, the light shielding portion 19c moves in the recessed portion 22a of the photo interrupter 22 located in the X1 direction.
  • the photo interrupter 22 outputs a low-level signal.
  • the second slider 20 since the second slider 20 does not receive an external force through the engaging protrusion 11 so as to remain in the neutral position, the signals output from the rest three photo interrupters located in the Y1-Y2 direction and the X2 direction are maintained at a high-level.
  • the engaging protrusion 11 moves in the X2 direction from the neutral position, and, in this case, the first slider 19 receives an external force through the engaging protrusion 11 so as to move in the X2 direction; therefore, the photo interrupter 22 located in the X2 direction outputs a low-level signal, and the signals output from the rest three photo interrupters 22 remain at a high-level.
  • the engaging protrusion 11 moves in the Y1 direction from the neutral position shown in Fig. 8 , since the engaging protrusion 11 relatively moves only within the elongated hole 19d elongated in the second direction (Y1-Y2 direction), the first slider 19 does not receive an external force through the engaging protrusion 11 so as to remain in the neutral position.

Meanwhile, when the rocking-operating force on the operating body 2 is removed, the lower end of the driving rod 13 receives the resilient force of the coil spring 12 so as to return to the center of the inner bottom surface of the cam groove 14; therefore, the entire operating body 2 including the holder 7 stands upright, and the engaging protrusion 11 or the first and second sliders 19 and 20 return to the neutral position automatically.
