  However, in the conventional combined operation type input device as described above, since the movable substrate on which the rotating electrical component is mounted slides, it is necessary to secure a space for sliding the movable substrate in the housing. . For this reason, there is a problem in that it is difficult to increase the outer diameter of the rotary electric component and to increase the torque during the rotation operation. On the other hand, it is conceivable to increase the outer shape of the rotating electrical component to increase the torque during the rotating operation. It is necessary to secure a space for use. For this reason, there exists a problem that the external shape of a housing becomes large and the external shape of a composite operation type input device becomes large.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a composite operation type input device capable of increasing torque during a rotation operation without increasing the outer shape of the device body. To do.

  The composite operation type input device of the present invention includes a housing having an external opening, an operation shaft that is exposed from the external opening and receives a rotation operation and a slide operation, and a rotation detection unit that detects the rotational movement of the operation shaft. A composite operation type input device comprising a slide detection means for detecting a slide movement of the operation shaft body, wherein the housing is divided into a first space facing the external opening and a second space, and an internal opening is provided. An intermediate member is provided, and the slide detection means is disposed in the first space, while the rotation body that constitutes the rotation detection means in the second space, a biasing member that elastically biases the rotation body, A transmission mechanism for transmitting the rotational movement of the operating shaft body to the rotating body while permitting the sliding movement of the operating shaft body is provided.

  According to the composite operation type input device, since the slide detection means is disposed in the first space and the rotation detection means is disposed in the second space, the slide detection means and the rotation detection means are laminated. Therefore, an increase in the size of the housing can be suppressed. On the other hand, the rotational movement is transmitted to the rotating body while allowing the sliding movement of the operating shaft body by the transmission mechanism, so that the rotating body can be configured not to slide regardless of the sliding movement of the operating shaft body. In addition, the size of the rotating body in the housing can be increased, and the torque during the rotation operation generated by the elastic biasing of the biasing member can be increased. As a result, it is possible to increase the torque during the rotation operation without increasing the outer shape of the apparatus main body.

  In the composite operation type input device, the transmission mechanism includes a transmission member in which a first transmission portion is formed on one surface and a second transmission portion orthogonal to the first transmission portion is formed on the other surface, and the operation shaft. A first rotating member formed with a first guide portion that rotates integrally with the body and guides the first transmitting portion in one direction, and rotates integrally with the rotating body, and the second transmitting portion is It is preferable to have the 2nd rotation member in which the 2nd guide part which guides to a direction was formed. In this case, the first transmission unit provided orthogonally is guided by the rotation force applied to the operating shaft body to the first guide portion of the first rotation member and the second guide portion of the second rotation member. Since the rotation is transmitted to the rotating body while absorbing the sliding movement of the operating shaft body by the movement of the transmission member, the sliding force of the operating shaft body is allowed. Thus, it is possible to reliably transmit the rotational movement to the rotating body.

  In the composite operation type input device, it is preferable that the rotating member constitutes the second rotating member. In this case, since the second rotating member is constituted by the rotating body, the number of constituent members housed in the housing can be reduced, and the operation shaft body can be downsized in the axial direction.

In this case, since the uneven portion that engages and disengages the engaging portion of the urging member is provided on the outer peripheral portion of the rotating body, the torque generated by the engagement and disengagement of the engaging portion is reduced to the limited surface area of the rotating body. It becomes possible to make it larger.

  In the composite operation type input device, the first rotating member is configured to be able to move a driving body that rotates integrally with the operation shaft body in the axial direction and to engage with the driving body in the circumferential direction.

A switch driving body guided so as to be movable in a direction is disposed, and the switch driving body is formed larger than the driving body and is provided between the driving body and the push switch. It is preferable. In this case, since the cylindrical portion provided in the second case guides the switch drive body formed larger than the drive portion in the axial direction of the operation shaft, the operation shaft body is slid. Even when a push operation is performed in a state, the push switch can be reliably operated.

  In the composite operation type input device, it is preferable that the push switch has a fixed contact exposed to the inside of the cylindrical portion and a movable contact disposed so as to be able to contact and separate from the fixed contact. . In this case, since the push switch is configured by the fixed contact exposed on the inner side of the cylindrical portion and the movable contact disposed so as to be able to come in contact with and away from the fixed contact, movement of the switch driver Accordingly, the push switch can be reliably operated.

  In the composite operation type input device, the second transmission portion is configured by a convex portion, the second guide portion is formed by a groove portion extending in a radial direction of the rotating body, and the rotation detection unit is configured to rotate the rotation. It is preferable that it is comprised from the body, the slider provided in the non-formation surface side of the said 2nd guide part in the said rotary body, and the electroconductive pattern which this slider slides. In this case, since the 2nd transmission part guided by the groove part provided in the rotary body is comprised by a convex part, it becomes possible to suppress the thickness dimension of transmission member itself in which a convex part is provided. .

  In the composite operation type input device, the intermediate member is formed of a plate-like member, and the slide detection means is movable in directions orthogonal to each other as the operation shaft body slides. Each of the slide members, and a contact pattern made of a metal plate provided on the plate member on which these sliders slide, and the plate member It is preferable that a terminal connected to the contact pattern is led out from. In this case, the contact pattern constituting the slide detection means is provided on the intermediate member, and the terminal connected to the contact pattern is led out from the intermediate member, thereby simplifying the configuration of the slide detection means and from the slide detection means. It is possible to reliably output the signal.

  According to the present invention, since the slide detection means is disposed in the first space, and the rotation detection means is disposed in the second space, the slide detection means and the rotation detection means can have a laminated structure. Therefore, it can suppress that the dimension of a housing becomes large. On the other hand, since the rotational movement is transmitted to the rotating body while allowing the sliding movement of the operating shaft body by the transmission mechanism, the rotating body can be configured not to slide regardless of the sliding movement of the operating shaft body. The size of the rotating body in the housing can be increased, and the torque during the rotation operation generated by the elastic biasing of the biasing member can be increased. As a result, it is possible to increase the torque during the rotation operation without increasing the outer shape of the apparatus main body.

And the bearing member 7 is arrange | positioned on the upper surface of the intermediate member 4 so that the lower end part (connection part 62a) of the operating shaft 6 may penetrate the opening part 41 of the intermediate member 4 which has arrange | positioned the slide members 8a and 8b in the predetermined position. . In this case, the slide members 8a and 8b are arranged so that the sliders 8e and 8f face the contact patterns 42a and 42b, respectively. Further, the driving body 11 is disposed in the insertion hole 123 of the first rotating member 12. In this case, the drive body 11 is disposed such that the plurality of ribs 112 engage with the recesses 124 provided on the inner wall surface of the insertion hole 123.

In this way, the assembly process of the input device 1 is completed.

  In addition, about the assembly process of the input device 1 shown in FIG.5 and FIG.6, it shows an example and is not limited to this, It can change suitably. As shown in FIG. 4, the constituent members of the input device 1 are accommodated in the upper space US and the lower space DS, and the wafer 17 is stacked on the lower surface of the lower case 3 and integrated with the mounting member 5. If possible, any assembly process may be employed.

  Next, operations when a rotation operation, a slide operation, and a push operation are performed on the operation shaft 6 of the input device 1 according to the present embodiment will be described with reference to FIG. In the following, the case where the rotation operation, the slide operation, and the push operation are performed independently on the operation shaft 6 will be described. However, in the input device 1 according to the present embodiment, two or more operations are performed. It is also possible to deal with cases where they are performed in combination. For example, it is configured to cope with a case where a rotation operation is performed while performing a slide operation.

  When the rotation operation is performed on the operation shaft 6, the driving body 11 connected through the connection portion 62 a having a non-circular shape rotates accordingly. When the driving body 11 rotates, the rib 112 provided on the outer periphery of the driving body 11 engages with the recess 124 provided on the inner wall surface of the cylindrical portion 122, and the first rotating member 12 also rotates. The rotational force applied to the first rotating member 12 is transmitted to the second rotating member 13 by a transmission mechanism including the first rotating member 12, a part of the second rotating member 13 and the transmitting member 14. When the second rotating member 13 rotates, the slider 134 a of the sliding member 134 fixed to the lower surface thereof slides on the conductive pattern 34. In the input device 1 according to the present embodiment, a rotation operation (a rotation operation amount and a rotation operation direction) with respect to the operation shaft 6 is detected according to a signal output according to the position of the slider 134a on the conductive pattern 34. Is done.

  Here, the configuration of the transmission mechanism of the input device 1 according to the present embodiment will be described. FIG. 7 is a perspective view for explaining the configuration of the transmission mechanism of the input device 1 according to the present embodiment. 7A, the first rotating member 12, the second rotating member 13, and the transmitting member 14 constituting the transmission mechanism are shown from above, and in FIG. 7B, the first rotating member 12 and the second rotating member 12 are shown. The rotating member 13 and the transmission member 14 are shown from the lower side.

  The transmission mechanism included in the input device 1 according to the present embodiment includes a groove 125 provided on the lower surface of the first rotating member 12, a groove 133 provided on the upper surface of the second rotating member 13, a groove 125 and a groove, respectively. 133 and the transmission member 14 having the convex portion 142 and the convex portion 143 accommodated in 133. As shown in FIG. 7A, in the base 141 of the transmission member 14, the straight line A passing through the pair of convex portions 142 and the straight line B passing through the pair of convex portions 143 are arranged in an orthogonal positional relationship. Yes. The same applies to the groove 125 and the groove 133 that accommodate the protrusion 142 and the protrusion 143, respectively.

  When the rotational force is applied to the first rotating member 12 in a state where the convex portion 142 and the convex portion 143 configured as described above are accommodated in the groove portion 125 and the groove portion 133, the transmission member 14 applies the rotational force to the convex portion 142. At the same time, it is rotated by the convex portion 143 while being transmitted to the second rotating member 13. The second rotating member 13 rotates by receiving the rotational force transmitted through the convex portion 143 at the groove portion 133. In this case, even when the rotation center of the first rotation member 12 and the rotation center of the second rotation member 13 are deviated, the transmission member 14 can transmit the rotational force while sliding the position. It has become. That is, the first rotating member 12 and the second rotating member 13 are Oldham coupled via the transmission member 14, and the rotational force is applied to the second rotating member 13 while allowing the first rotating member 12 to slide. It is something that can be communicated. In particular, in the input device 1 according to the present embodiment, since the transmission mechanism is configured by a part of the second rotating member 13, the number of components stored in the housing can be reduced, and the operation shaft 6 can be reduced. It is possible to reduce the size in the axial direction.

  Thus, the 2nd rotation member 13 which receives transmission of a rotational force through the transmission mechanism couple | bonded with Oldham can be rotated without moving the rotation center. As shown in FIG. 8, the urging pieces 152 and 153 of the leaf spring 15 elastically urges the uneven portion 132 provided on the outer peripheral portion of the upper surface of the second rotating member 13 rotating in this way. For this reason, the torque generated by the elastic urging of the urging pieces 152 and 153 of the leaf spring 15 (particularly engagement / disengagement of the engaging portion 152a with the concavo-convex portion 132) is reduced to a limited surface area of the second rotating member 13. It is possible to make it as large as possible.

  Moreover, in this transmission mechanism, since the convex part 142,143 guided to the groove part 125 and the groove part 133 each provided in the 1st rotation member 12 and the 2nd rotation member 13 is provided as a transmission part, a transmission member 14 can suppress the thickness dimension of the base 141 itself.

  When a slide operation is performed on the operation shaft 6, the operation shaft 6 is inserted into the operation shaft 6 (more specifically, the driving body 11 connected to the operation shaft 6) through the openings 8c and 8d. The slide members 8a and 8b thus moved slide inside the upper case 2. Here, the operation of the slide members 8a and 8b according to the slide operation on the operation shaft 6 will be described with reference to FIG. FIG. 9 is a perspective view for explaining the operation of the slide members 8a and 8b of the input device 1 according to the present embodiment. In FIG. 9, the upper case 2 and the bearing member 7 are omitted for convenience of explanation.

  When a slide operation is performed on the operation shaft 6 in the X direction shown in FIG. 9, the slide member 8a is moved in the X direction. Accordingly, the slider 8e fixed to the lower surface of the slide member 8a slides on the contact pattern 42a of the intermediate member 4. In the input device 1 according to the present embodiment, a sliding operation (sliding operation amount) in the X direction with respect to the operation shaft 6 is detected according to a signal output according to the position of the slider 8e on the contact pattern 42a. The Similarly, when a slide operation is performed in the Y direction shown in FIG. 9, the slider 8 f fixed to the lower surface of the slide member 8 b slides on the contact pattern 42 b of the intermediate member 4. In the input device 1 according to the present embodiment, a sliding operation in the Y direction with respect to the operating shaft 6 is detected according to a signal output according to the position of the slider 8f on the contact pattern 42b.

  Further, when a sliding operation is performed in the Z direction shown in FIG. 9, the sliders 8e and 8f fixed to the lower surfaces of the sliding members 8a and 8b slide on the contact patterns 42a and 42b of the intermediate member 4, respectively. In the input device 1 according to the present embodiment, a sliding operation in the Z direction with respect to the operation shaft 6 is detected according to a signal output according to the position of the sliders 8e and 8f on the contact patterns 42a and 42b. . In these cases, since the signal from the slide detection means is output via the external output terminal 42c connected to the contact patterns 42a and 42b provided on the intermediate member 4, the configuration of the slide detection means is simplified. In addition, the signal output from the slide detection means can be reliably performed.

  When the operation shaft 6 slides, the first rotating member 12 slides accordingly. Depending on the sliding direction, the transmission member 14 also slides. However, in the slide movement, the transmission member 14 is converted into a slide movement along the groove 125 and the groove 133 by the transmission mechanism described above, and the second rotating member 13 does not slide. That is, the horizontal moving force accompanying the sliding movement of the operation shaft 6 is absorbed by the transmission mechanism and is not transmitted to the second rotating member 13.

  When a push operation is performed on the operation shaft 6, the operation shaft 6 moves downward independently of the bearing member 7. Along with this, the driving body 11 moves downward and pushes down the switch driving body 16. When the switch driving body 16 is pushed down beyond a certain position, the elastic member 19 supporting the switch driving body 16 is reversed, and the movable contact 18b is pushed down at the lower end thereof to contact the fixed contact 18a. When the fixed contact 18a and the movable contact 18b come into contact with each other, they are electrically connected, and the push switch 18 is turned on.

  On the other hand, when released from the push operation, the switch driver 16 is pushed up by the elastic restoring force of the elastic member 19. Thereby, the push switch 18 is turned off by moving the movable contact 18b away from the fixed contact 18a. When the switch driving body 16 is pushed up, the driving body 11 and the operation shaft 6 connected to the driving body 11 are pushed up to return to the initial state. In this way, the on / off state of the push switch 18 is switched according to the push operation on the operation shaft 6.

  In the input device 1 according to the present embodiment, the second rotating member 13 and the transmission member 14 are provided with an opening 131 or the like through which the driving body 11 can pass, and the driving body 11 is moved along with the movement of the operation shaft 6 in the axial direction. Since the push switch 18 can be driven without interposing the second rotating member 13 and the transmission member 14, the push switch can be stably operated. . In this case, since the switch drive body 16 pushed down by the drive body 11 is configured to be larger than the pressing portion 113 of the drive body 11, even when the slide operation is simultaneously performed on the operation shaft 6. The elastic member 19 can be pushed down, and the on / off state of the push switch 18 can be switched.

  As described above, in the input device 1 according to the present embodiment, the slide detection means including the slide members 8a and 8b is disposed in the upper space US, while the rotation including the second rotation member 13 in the lower space DS. Since the detection means is provided, the slide detection means and the rotation detection means can be formed in a laminated structure, so that an increase in the size of the housing composed of the upper case 2 and the lower case 3 can be suppressed. . On the other hand, the rotational movement is transmitted to the second rotational member 13 while allowing the sliding movement of the operation shaft 6 by the transmission mechanism constituted by the first rotational member 12, a part of the second rotational member 13 and the transmission member 14. Therefore, the second rotating member 13 can be configured not to slide regardless of the sliding movement of the operation shaft 6, so that the size of the second rotating member 13 in the housing can be increased, and the elasticity of the leaf spring 15 can be increased. The torque at the time of the rotation operation generated by the urging can be increased. As a result, it is possible to increase the torque during the rotation operation without increasing the outer shape of the apparatus main body.

  In addition, this invention is not limited to the said embodiment, It can change and implement variously. In the above-described embodiment, the size, shape, and the like illustrated in the accompanying drawings are not limited to this, and can be appropriately changed within a range in which the effect of the present invention is exhibited. In addition, various modifications can be made without departing from the scope of the object of the present invention.

  For example, in the above-described embodiment, a part of the transmission mechanism that transmits the rotational force accompanying the rotational operation with respect to the operation shaft 6 to the second rotating member 13 is configured by a part of the second rotating member 13 (groove portion 133). Although the case has been described, the configuration of the transmission mechanism is not limited to this and can be changed as appropriate. For example, a rotating member that rotates integrally with the second rotating member 13 and has a function in common with the groove 133 may be provided separately. Even in this case, similarly to the above-described embodiment, it is possible to reliably transmit the rotational movement to the second rotating member 13 while permitting the sliding movement of the operation shaft 6.

  In the above-described embodiment, the transmission mechanism that transmits the rotational force associated with the rotation operation on the operation shaft 6 to the second rotation member 13 includes the groove portion 125 provided on the lower surface of the first rotation member 12 and the second rotation. Although the case where it comprises with the groove part 133 provided in the upper surface of the member 13, and the transmission member 14 which has the convex part 142 and the convex part 143 which are each accommodated in the groove part 125 and the groove part 133 is demonstrated, the structure of a transmission mechanism Is not limited to this, and can be changed as appropriate. For example, you may make it replace the groove part provided in the 1st rotation member 12 and the 2nd rotation member 13, and the convex part provided in the transmission member 14. FIG. In addition, it is possible to employ any shape that can Oldham-couple the first rotating member 12, the second rotating member 13, and the transmission member 14.

  In the above embodiment, the leaf spring 15 as an urging member that elastically urges the second rotating member 13 is attached to the lower case 3, and the urging pieces 152 and 153 are elastically contacted with the second rotating member 13. However, the present invention is not limited to this. For example, by attaching a leaf spring to the second rotating member 13 and elastically pressing the biasing piece of the leaf spring against the lower surface of the intermediate member 4, an elastic biasing force by the leaf spring acts on the second rotating member 13. It is also possible to configure so as to.

  Further, when the click feeling is not required during the rotation operation on the operation shaft 6, the second rotating member 13 may not be provided with the uneven portion 132.

  Furthermore, the urging member is not limited to a leaf spring, and for example, a member using rubber or a coil spring may be used.
