JP 2003-242862 A

  The multi-contact type multi-directional input device includes a body as a basic component, a movable body supported by the body so as to slide and move in all directions from the origin position, a movable contact equipped as a common electrode on the movable body, A plurality of fixed contacts fixed at a plurality of locations on the body so as to surround the origin position. The moving body usually also serves as a control key, and when the user slides the moving body in a desired direction, the movable contact mounted on the moving body is brought into contact with the fixed contact located in the moving direction. A digital signal corresponding to the operation direction is generated and output to the device used.

  The features of this type of multi-directional input device are that it is easy to reduce the thickness because the operation method is a horizontal slide method, and the cost is because the output method is a digital method that combines a movable contact and a fixed contact. However, due to these advantages, the demand for input devices in electronic devices such as controllers for game machines and mobile phones that are highly demanded for economy and miniaturization has increased rapidly. Yes.

  However, on the other hand, there are the following disadvantages. The moving body, which is a control key, is slid in the peripheral direction, but there are also cases in which an operation is performed around the origin at the slide position. Due to the fact that multiple fixed contacts are intermittently arranged in the circumferential direction around the origin position, the fixed contacts do not conduct continuously in the operation of rotating the control key. Switches on, off, on, off ... For this reason, since the output signal is interrupted and the continuity is lost in the off section, the display is also interrupted on, off, on, off,... When performing continuous image display.

  On the other hand, an analog output method using a piezoelectric element or an electrostatic method does not cause such a problem of discontinuity, but there are problems such as a high element cost, an obstacle due to an RF signal, and a difficulty in miniaturization.

  The present invention was devised in view of such circumstances, and is an inexpensive and stable digital method based on a combination of a movable contact and a fixed contact, and an output signal when the slide type moving body circulates around the origin at the slide position. It is an object of the present invention to provide a multi-contact type multi-directional input device and an electronic apparatus using the multi-contact type which can avoid the interruption of the signal and enable continuous signal output equivalent to the analog output method.

In order to achieve the above object, a multidirectional input device according to the present invention is equipped with a body, a moving body supported by the body so as to slide and move in all directions from the origin position, and the moving body as a common electrode. And a plurality of fixed contacts that are fixed at a plurality of locations on the body so as to surround the origin position, and are arranged so as to be in contact with the movable contacts when the moving body slides around. In the multi-contact type multi-directional input device comprising the movable contact, the movable contact always maintains contact with the fixed contact 1 or 2 when the movable body circulates around the origin position while sliding with a full stroke. and have a contact structure, the moving body also serves as a control key as an operation member, the control keys equipped with a stopper for preventing dislodgement from the body And, the stopper is fitted in the recess of the body so as to prevent rotation of the control keys.

  In the multidirectional input device according to the present invention, the movable contact always has a contact structure that maintains a contact state with one or two fixed contacts when the moving body circulates in a full-sliding state. It is possible to output a signal without any interruption in the operation direction even in a circular operation with the contact structure. Specifically, for example, when eight fixed contacts are arranged in the clockwise direction, when the movable contacts are simultaneously in contact with the “upper” and “upper right” fixed contacts, “upper”, “upper right” and “right” When a movable contact comes into contact with the fixed contact at the same time, a software process such as “right” is performed.

At this time, if simultaneous contact with three or more fixed contacts occurs, software processing for signal output becomes difficult. In order to avoid simultaneous contact with three or more fixed contacts, for example, a measure to make the movable contact small is conceivable. However, if this is done, the stroke to contact becomes long and the operability deteriorates. For this, it is preferable that the plurality of fixed contacts have a non-parallel structure in which tip portions are inclined with respect to a tangent of a circle centering on the origin position. Thereby, simultaneous contact with three or more fixed contacts can be avoided with a short stroke. Moreover, since the moving body also serves as a control key as an operation member, the number of parts can be reduced. Furthermore, the control key is equipped with a stopper that prevents the control key from coming off, and the stopper is fitted in the recess of the body to prevent the control key from rotating (rotating). The configuration in which the stopper for preventing slipping also serves as the rotation stopper makes it possible to reduce the number of parts.

The multi-directional input device has a contact structure in which the movable contact always maintains contact with the fixed contact 1 or 2 when the movable body circulates around the origin position in a state of sliding with a full stroke. In addition, the origin returning member of the moving body is a spiral spring material circumscribing the moving body and inscribed in the body. This spring material is thin, which contributes to thinning of the device and has an advantage that the slide operation force can be easily controlled.

The multi-directional input device has a contact structure in which the movable contact always maintains contact with the fixed contact 1 or 2 when the movable body circulates around the origin position in a state of sliding with a full stroke. The movable contact is an annular body concentrically attached to the moving body and is rotatable with respect to the moving body. With this configuration, the movable contact does not rotate together when the moving body goes around. Therefore, sliding between the movable contact and the surrounding fixed contact is avoided, and wear of both contacts is suppressed.

Moreover, it can also be set as the leaf | plate spring structure which contacts the corresponding circuit of a board | substrate surface elastically with the mounting to a board | substrate. According to the leaf spring structure, the work of soldering the lead terminal portion to the substrate becomes unnecessary, and the assembly workability is improved.

  The body 10 is a substantially octagonal board, and a circular through hole 11 is provided at the center thereof. On the upper surface of the body 10, eight concave portions 12 are provided so as to surround the through holes 11, and through holes 13 are provided outside the concave portions 12. The eight concave portions 12 are contact holding portions that receive and hold the fixed contacts 20, and are provided at equal intervals in the circumferential direction. Further, four convex portions 14 are provided on the upper surface of the body 10 at equal intervals in the circumferential direction so as not to interfere with the concave portions 12 and the through holes 13. The four convex portions 14 are holding portions that hold the origin return member 60 inside.

  On the other hand, a rectangular recess 15 is provided on the lower surface of the body 10, as shown in FIGS. The recess 15 is a stopper that prevents the rotation (spinning) of the control key 70, and interferes with the through hole 11 at the center of the body 10, and its long side is larger than the diameter of the through hole 11, and the short side Is set smaller than the diameter of the through hole 11. Another concave portion 16 having a rectangular shape is provided on the lower surface of the body 10. The recess 16 is a housing portion for the key dome 110, and is perpendicular to the recess 15 and shallower than the recess 15.

  The plurality of fixed contacts 20 correspond to the eight concave portions 12. As shown in FIGS. 4, 6, and 7, each fixed contact 20 has a main body portion that is press-fitted and held in the recess 12, and a connection portion that extends rearward from the main body portion. More specifically, the main body portion includes a U-shaped elastic deformation portion 21 that is press-fitted into the concave portion 12 and a contact portion 22 that extends horizontally inward from one end portion thereof. The connecting portion includes an arm portion 23 that extends horizontally outward from the elastic deformation portion 21, and a terminal portion 24 that has a leaf spring structure that extends inward from the distal end portion of the arm portion 23 via a bending portion. Yes. The terminal portion 24 is formed as a tongue-shaped contact piece that protrudes downward from the through hole 13 provided on the outer side of the concave portion 12 and is inclined downward toward the inner side.

  The horizontal contact portion 22 provided at the tip of the fixed contact 20 is supported at the same level as the upper surface of the body 10 (FIG. 6), and the inner end surface thereof is a tangent of a circle concentric with the center of the body 10. Are inclined in the same direction at the same angle θ (FIG. 7). Here, the inclination angle θ is preferably 5 to 20 degrees.

  As shown in FIGS. 3 and 4, the metal cover 30 includes a substantially octagonal top plate portion 31 that overlaps the body 10, and eight side wall portions that extend downward from each side of the top plate portion 31. The movable contact 40 is disposed between the body 10 and the top plate portion 31. There are two types of side walls of the metal cover 30, a main body holding part 32 and a terminal holding part 33, and they are provided alternately in the circumferential direction.

  A circular through hole 34 is provided at the center of the top plate portion 31. The through hole 34 is concentric with the through hole 11 of the body 10 and has substantially the same diameter as the through hole 11 of the body 10. Around the through hole 34, a plurality of dome-shaped bulges 35 are provided at equal intervals in the circumferential direction. The plurality of bulging portions 35 protrude downward to make the top plate portion 31 elastically contact the movable contact 40 on the back surface side. The main body holding part 32 has a rectangular opening 36 into which the claw part 17 of the body 10 is fitted. The opening 36 is provided on the top plate portion 31 side so as to project the four convex portions 14 upward from the top plate portion 31. A terminal portion 37 protrudes from the lower end portion of the terminal holding portion 33. The terminal portion 37 is a tongue-like contact piece similar to the terminal portion 24 having the leaf spring structure, and protrudes downward from the body 10 and is inclined downward toward the inside.

  The control key 70 is a movable body that also serves as an operation member, and includes a disk-shaped operation portion 71 and a round bar-shaped shaft portion 72 that protrudes downward from the center thereof. The operation unit 71 is a disc having substantially the same size as the body 10. The keypad 80 is a cap made of a disk-shaped elastic body, and covers the operation unit 71. The shaft portion 72 of the control key 70 is inserted into the through hole 11 of the body 10 through the through hole 34 of the metal cover 30. The control key 70 is prevented from coming off by a stopper terminal 90 attached to the shaft portion 72 from the lower surface side of the body 10.

  The outer diameter D of the shaft portion 72 of the control key 70 is set smaller than the inner diameter d of the through hole 11 of the body 10 and is smaller than the inner diameter of the through hole 34 of the metal cover 30 (FIG. 2). For this reason, the control key 70 can be slid in all the directions perpendicular to the center line. The stopper terminal 90 has a pair of flanges 91 and 91. The pair of flanges 91 and 91 are fitted in a rectangular recess 15 provided on the lower surface of the body 10 (FIG. 5). Here, the flanges 91 and 91 are smaller than the recess 15 and are fitted in the recess 15 with a degree of freedom. With this degree of freedom, the control key 70 is allowed to slide in all directions, and the flanges 91, 91 abut against the inner wall surface of the recess 15, thereby rotating (rotating) around the center of the shaft portion 72. Be blocked.

  The annular movable contact 40 is fitted to the shaft portion 72 so as to slide together with the shaft portion 72 of the control key 70, and more specifically, is rotatably fitted to the shaft portion 72. The movable contact 40 is located between the upper surface of the body 10 and the top plate portion 31 of the metal cover 30. More specifically, even if the control key 70 slides at a full stroke, the movable contact 40 is arranged around the through hole 11 of the body 10 and the ceiling. The movable contact 40 is designed so as to be held between the periphery of the through hole 34 of the plate portion 31 (FIG. 4). As a result, the movable contact 40 slides together with the radial sliding operation of the control key 70. The movable contact 40 and the metal cover 30 are ensured to be in a conductive state by elastic contact by the bulging portion 35 around the through-hole 34 regardless of the moving position of the movable contact 40.

  The annular insulating sheet 50 is between the plurality of fixed contacts 20 attached to the body 10 and the metal cover 30 and electrically insulates them (FIG. 4).

  The origin returning member 60 is a spiral spring here as shown in FIG. The spiral spring is disposed between the top plate portion 31 of the metal cover 30 and the operation portion 71 of the control key 70. More specifically, the four convex portions of the body 10 projecting above the top plate portion 31. 14 and circumscribed to the shaft portion 72 of the control key 70. As a result, the control key 70 is elastically held at the origin position concentric with the central portion of the body 10.

  Here, the positional relationship between the movable contact 40 and the plurality of fixed contacts 20 will be described in more detail with reference to FIG.

  As shown in FIG. 9, in the multidirectional input device according to this embodiment, eight fixed contacts 20 (upper, upper right, right, lower right, lower, lower left, left, upper left in the figure) are concentric with the body 10. Are arranged at regular intervals in a clockwise direction, and an annular movable contact 40 that slides integrally with the control key 70 is disposed inside thereof. When an external force in the sliding direction is not applied to the control key 70, the movable contact 40 is inside the eight fixed contacts 20 and does not contact any fixed contact 20.

  When the control key 70 is operated upward in FIG. 9, the movable contact 40 comes into contact with the “upper” fixed contact 20. More specifically, a part in the circumferential direction of the movable contact 40 overlaps and contacts the contact portion 22 of the fixed contact 20 (FIG. 6). Assuming that the control key 70 is rotated in the clockwise direction around the origin in the state where the control key 70 is fully stroked upward in FIG. 9, the movable contact 40 is moved to the “upper” fixed contact 20 and the “upper right” fixed contact 20. Simultaneous contact. When further rotated, the movable contact 40 contacts only the “upper right” fixed contact 20. That is, the movable contact 40 and the fixed contact 20 are maintained so that the movable contact 40 is always in contact with the fixed contact 20 of 1 or 2 when the control key 70 slides around the origin with the full stroke. It is designed.

  Here, the following software processing is performed on the signal. For example, when outputting direction signals in four directions (up, right, down, left), if the fixed contact 20 that contacts the movable contact 40 is “up”, the output signal is “up”. When the fixed contact 20 is “upper” and “upper right”, the output signal is “upper”. When the fixed contact 20 is “upper right”, the output signal is “up”. When the fixed contact 20 is “upper right” and “right”, the output signal is “right”. When the fixed contact 20 is “right”, the output signal is “right”. When the fixed contact 20 is “right” and “lower right”, the output signal is “right”. When the fixed contact 20 is “lower right”, the output signal is “lower”. When the fixed contact 20 is “lower right” and “lower”, the output signal is “lower”. When the fixed contact 20 is “lower”, the output signal is “lower”.

  When the fixed contact 20 is “lower” and “lower left”, the output signal is “lower”. When the fixed contact 20 is “lower left”, the output signal is “lower”. When the fixed contact 20 is “lower left” and “left”, the output signal is “left”. When the fixed contact 20 is “left”, the output signal is “left”. When the fixed contact 20 is “left” and “upper left”, the output signal is “left”. When the fixed contact 20 is “upper left”, the output signal is “up”. When the fixed contact 20 is “upper left” and “upper”, the output signal is “upper”.

  By such signal processing on the software, even when the control key 70 is rotated around the origin (full revolution) with the full stroke, the output signal can be prevented from being interrupted, and it is the same as the analog output method. Signal output is possible. In addition, signal output in eight directions is possible by the same software processing.

  As shown in FIG. 10, the substrate 100 fixed to the lower surface of the body 10 has eight terminal portions 101 arranged concentrically on the surface. Eight fixed contacts 20 are in contact with these. On the surface of the substrate 100, four terminal portions 102 with which the terminal portions 37 of the metal case 30 come into contact are provided so as not to interfere with the terminal portions 101, and are surrounded by these terminal portions 3 for push switch 3. Two terminal portions 103, 104, and 105 are provided.

  The substrate 100 is attached to the lower surface of the body 10 by fixing means (not shown). By this attachment, the terminal portions 24 of the leaf spring structure of the eight fixed contacts 20 are brought into elastic contact with the corresponding terminal portions 101. In addition, the four leaf spring structure terminal portions 37 provided on the metal cover 30 are in elastic contact with the corresponding terminal portions 102.

  The key dome 110 disposed on the substrate 100 is accommodated and positioned in a rectangular recess 16 provided on the lower surface of the body 10, and is pushed down by the shaft portion 72 of the control key 70 disposed above the key dome 110. The The key dome 110 has a multi-stage structure including a square frame-shaped first dome portion 111 and an oval second dome portion 112 held inside thereof. One end of the square frame-shaped first dome portion 111 is always in contact with the first terminal portion 103 for the push switch in the substrate 100, and the other end portion is the second terminal portion when the first step of the control key 70 is pushed. 104 is brought into contact with each other to conduct between the terminal portions 103 and 104. The inner second dome portion 112 comes into contact with the third terminal portion 105 by pushing the control key 70 in the second step, and conducts between the first terminal portion 103 and the third terminal portion 105.

  The control key 70 is elastically held at the upper limit position by the outer peripheral portion of the keypad 80 attached to the disk-like operation portion 71, and the key dome 110 is pressed by a pressing operation against the holding force. To operate.

  The function of the multi-directional input device configured as described above is as follows.

  A control key 70 that is a moving body slides in all directions, and the movable contact 40 comes into contact with one or two fixed contacts 20 positioned in the sliding direction, so that a signal in the moving direction is output. Since it is a digital system in which the movable contact 40 and the plurality of fixed contacts 20 are combined, the component cost is low and the economy is good.

  The control key 70 can circulate around the origin while sliding. When such a rounding operation is performed with a full stroke, the movable contact 40 contacts at least one of the surrounding fixed contacts 20 and does not contact three. That is, the fixed contact 20 of 1 or 2 is surely contacted. For this reason, the output signal is not interrupted, and a continuous display is possible even when continuous image display is performed.

  In this case, as described above, it is necessary to avoid a situation in which the movable contact 40 contacts the three fixed contacts 20 simultaneously. In order to avoid simultaneous contact with the three contacts, it is necessary to make the movable contact 40 small. However, if this is done, the movement stroke in the horizontal direction becomes large and the operability deteriorates. For example, when the control key 70 is rotated in the sliding state, there is a high risk that the movable contact 40 is not brought into contact with the fixed contact 20, that is, the so-called idling is not performed. However, in the fixed contact 20 here, the tip of the contact portion 22 is inclined at the same angle θ in the same direction with respect to a tangent of a circle concentric with the center (origin) of the body 10. For this reason, it becomes difficult to make simultaneous contact with the three contacts, and an increase in the movement stroke and a deterioration in operability due to this are avoided.

  In such a turning operation of the control key 70, if the movable contact 40 is fixed to the shaft portion 72 of the control key 70, the movable contact 40 comes into sliding contact with the fixed contact 20 in order, and friction and contact wear due to this are caused. It becomes a problem. However, the movable contact 40 is rotatable with respect to the shaft portion 72 of the control key 70 here. For this reason, the movable contact 40 rotates in the reverse direction relative to the rotation of the control key 70, and friction with the fixed contact 20 and wear due thereto are reduced.

  A planar spiral spring is used as the origin return member 60 for returning the control key 70 to the origin. For this reason, the overall height of the multidirectional input device can be suppressed.

  The stopper terminal 90 that prevents the control key 70 from coming off is fitted into a rectangular recess 15 formed on the lower surface of the body 10 to prevent rotation. For this reason, the control key 70 does not rotate. When characters or symbols are displayed on the surface of the keypad 80 when the control key 70 rotates, the direction of these changes, but the problem of changing the display direction is solved by preventing the control key 70 from rotating.

  The movable contact 40, which is a common terminal, is provided with a plurality of downwardly protruding bulged portions 35 around the center portion of the top plate portion 31 of the metal cover 30, so that the control key 70 slides in any direction. However, the top plate portion 31 is always in elastic contact regardless of the slide position. The metal cover 30 is electrically connected to the substrate 100 by elastically contacting the corresponding terminal portions 102 of the substrate 100 with the terminal portions 37 having four leaf spring structures. Therefore, the movable contact 40 is reliably connected to the substrate 100 with a simple configuration using the metal cover 30.

  Each of the terminal portion 24 of the fixed contact 20 and the terminal portion 37 of the metal cover 30 is a tongue-like piece having a leaf spring structure, and is electrically connected to a corresponding circuit of the substrate 100 as the substrate 100 is attached to the body 10. This eliminates the need for soldering the terminal portions 24 and 37 and simplifies the assembly of the apparatus.

  The control key 70 also serves as an operation unit of the push switch, and can process the output signal as a determination signal. In particular, the push switch here uses a two-stage operation type key dome 110 disposed on the substrate 100. For this reason, the output signal can be processed as a two-stage signal (multistage signal) of provisional determination and final determination.

That is, in the above-described multidirectional input device (FIG. 6), the contact portion 22 of the fixed terminal 20 is flat and is at the same level as the upper surface of the body 10, and the movable contact 40 slides on the upper surface. However, in the multidirectional input device according to the present embodiment, the tip end portion of the contact portion 22 bends upward, and the outer peripheral surface of the movable contact 40 contacts this.
