Description

  The present invention relates to an antenna device used in an electronic device such as a wireless receiver.

  As shown in FIG. 13, the conventional antenna device is configured to support the antenna on the upper surface of the electronic device. In the example of FIG. 13, the electronic device is the receiver 201, and the antenna 203 is inserted into the connector 205 on the upper surface of the receiver 201, rotated, and fixed to the receiver 201. Two antennas 203 are arranged apart from each other to constitute a diversity antenna of the wireless receiver. In use, the antenna 203 is always fixed in a standing posture at an angle of 90 degrees. When stored, the antenna 203 is detached from the receiver 201. And receiver 201 and antenna 203 are stored separately.

  Such receivers and antennas are used, for example, in the field of electronic news gathering (ENG) and electric field production (EFP). A receiver is attached to the rear of the ENG camera and used for news gathering. The receiver is carried in a bag together with a portable mixer and a battery, and is used for EFP program production.

Patent Document 1 discloses an antenna device provided in a portable wireless communication device such as a cellular phone. The antenna is provided so as to be housed by rotating with respect to the apparatus main body.
JP 2001-177315 A (page 2-3, FIG. 1)

  However, in the conventional antenna device as shown in FIG. 13, since the antenna is fixed to the receiver, the antenna and the electronic device are directly subjected to a load applied to the antenna due to an unexpected impact or the like. There was a problem that could be damaged. In addition, since the antenna and the electronic device are separated, there is a problem that it takes time and labor to set and store the antenna. In particular, in the case of antennas of receivers such as ENG and EFP, in consideration of the situation in the field, it is desired to prevent damage due to the load on the antenna, and further, it is strongly desired to speed up setting and storage.

  Since the antenna device of Patent Document 1 falls when a load is applied to the antenna, damage can be prevented. However, when the angle when the antenna is used is determined as in the example of the wireless receiver described above, there is a problem that the essential antenna function cannot be obtained even though the antenna can be prevented from being damaged. is there.

  An antenna that is elastically bendable is also known. However, this prior art can be applied only in some cases. That is, when it is assumed that an antenna that cannot be bent is used, this conventional technique cannot be applied.

  The present invention has been made to solve the conventional problems, and an object of the present invention is to provide an antenna device that can prevent damage when a load is applied to the antenna due to an unexpected impact or the like.

  The antenna device of the present invention includes an antenna, a connector to which the antenna is connected, a base portion that rotatably supports the connector, and an elastic member that positions the connector at a predetermined set position. A positioning mechanism, and the elastic positioning mechanism is a mechanism that applies an elastic force for returning to the set position to the connector rotated from the set position.

  With this configuration, a mechanism for elastically positioning the connector to which the antenna is connected at a predetermined set position is provided. In this mechanism, the connector is allowed to rotate, but when the connector rotates, an elastic force is applied and the connector returns to its original position. The base of the antenna fixing portion can be flexibly inclined. When a load is applied to the antenna, the antenna falls, and when the load is removed, the antenna returns to the set position. Therefore, it is possible to prevent damage when a load is applied to the antenna due to an unexpected impact or the like.

  Further, in the antenna device of the present invention, the connector is supported on the base portion by a first rotation shaft and a second rotation shaft that intersect each other, and the elastic positioning mechanism has the first rotation shaft. A first positioning member that rotates with the connector about an axis, a second positioning member that rotates with the connector about the second rotation axis, and a rotation of the first positioning member. A first elastic member for applying an opposing elastic force to the first positioning member, and a second elastic member for applying an elastic force to the second positioning member to counter the rotation of the second positioning member And.

  With this configuration, a mechanism for elastically positioning the antenna by a relatively simple configuration that supports the antenna so as to be rotatable about two axes and applies an elastic force against the rotation around each axis. realizable.

  Further, in the antenna device of the present invention, the base portion is a fixed base portion, a rotation base portion that is rotatably supported with respect to the fixed base portion and supports the connector, an operation portion, and the A base drive mechanism that rotates the rotating base portion between an upright position and a recumbent position with respect to the fixed base portion in conjunction with an operation on the operating portion.

  With this configuration, the base drive mechanism rotates the rotating base portion between the standing position and the recumbent position with respect to the fixed base portion in conjunction with the operation on the operation portion. Can be reduced.

  In the antenna device of the present invention, the base drive mechanism is coupled to a button that is the operation unit, and a slide frame provided on the fixed base unit so as to be slidable in conjunction with a button operation; and the slide A gear mechanism that has a drive gear for the frame and a driven gear for the rotation base portion, and rotates the rotation base portion in response to the slide of the slide frame; and the gear mechanism raises the rotation base portion An upright state holding mechanism that holds the slide frame in a state rotated to a position; and a recumbent state holding mechanism that holds the slide frame in a state where the gear mechanism rotates the rotation base portion to the recumbent position. I have.

  With this configuration, a slide frame that slides relative to the fixed base in conjunction with a button operation on the operation unit is provided, and a gear mechanism is provided on the slide frame and the rotation base to hold the slide frame in an upright state and a recumbent state. The base drive mechanism can be realized by a relatively simple configuration such as providing a mechanism for performing the above operation. And storage and setting are possible by button operation, and labor and time can be reduced.

  Further, in the antenna device of the present invention, the two antennas are arranged so as to stand side by side, and are provided with two connectors and two base portions that respectively hold the two antennas, and the base drive of each base The two base portions are arranged so that the recumbent direction by the portion faces the base portion of the other party.

  With this configuration, when the two antennas are arranged at intervals of twice or less the antenna length, the two antennas can be stored compactly side by side. Here, in this invention, both the base drive mechanism which rotates a rotation base, and the elastic positioning mechanism of a connector are provided. As a result, the elastic positioning mechanism acts during the storing operation of the base drive mechanism, and changes the direction so that the two antennas naturally pass each other. That is, the two antennas do not stop when they collide, but pass each other and lie side by side after the collision. Accordingly, the two antennas can be stored compactly side by side in spite of a simple configuration in which the two base portions are simply faced on the electronic device, and the two antennas can be set up in parallel when standing. In particular, in a configuration in which two antennas such as diversity are arranged side by side on a thin electronic device, the above compact storage is very effective.

  Another aspect of the present invention is an antenna holding device, which includes a connector to which an antenna is connected, a base portion that rotatably supports the connector, and the base portion. An elastic positioning mechanism for positioning at a predetermined set position, and the elastic positioning mechanism is a mechanism for applying an elastic force for returning to the set position to the connector rotated from the set position. This configuration also provides the advantages of the present invention described above.

  Another aspect is an electronic device including the above-described antenna device or antenna holding device, and the electronic device is, for example, a wireless receiver. This configuration also provides the advantages of the present invention described above.

  The present invention enables a flexible inclination of the base of the antenna fixing portion by providing a mechanism for elastically positioning the connector to which the antenna is connected at a predetermined set position, thereby enabling a load on the antenna due to an unexpected impact or the like. Thus, it is possible to provide an antenna device having an effect of preventing damage when the is added.

  Hereinafter, an antenna device according to an embodiment of the present invention will be described with reference to the drawings.

  An antenna device according to an embodiment of the present invention is shown in FIGS. FIG. 2 shows a configuration of the entire electronic device in the antenna use state and the antenna storage state. In the present embodiment, the electronic device is the receiver 1, and more specifically, a wireless receiver such as ENG or EFP. The antenna device 3 includes an antenna 5 and an antenna holding unit 7, and the antenna holding unit 7 is provided on the receiver 3.

  The antenna 5 has a rod shape, and the antenna 5 has a circular cross section. In the present embodiment, the two antennas 5 are held by the two antenna holding units 7 to form a diversity antenna. The two antenna holding portions 7 have the same configuration, and are disposed at both ends of the upper surface of the thin casing of the receiver 3 as shown in the figure. Thus, the antenna device 3 includes two antennas 5 and two antenna holding units 7. (However, one antenna may be used within the scope of the present invention. In addition, in the above configuration, a combination of one antenna and an antenna holding portion may be referred to as an antenna device).

  In the present embodiment, in the antenna use state, the antenna 5 is held by the antenna holding unit 7 and stands upright. In the antenna storage state, the antenna 5 is brought down. As will be described later, the standing and storing of the antenna 5 are realized by a one-touch operation on the button 9.

  Further, as indicated by an arrow in FIG. 2, the antenna 5 can be tilted in an arbitrary direction when the antenna is used. When the antenna 5 falls, an elastic force is applied and the antenna 5 returns to the original standing state. This function is realized by a mechanism provided in the antenna holding unit 7.

  In the following description, the direction when the antenna 5 in FIG. 2 lies down (the direction of the line connecting the two antennas 5) is referred to as the X direction, and the direction perpendicular to the X direction is referred to as the Y direction.

  FIG. 1 is a perspective view of the antenna holding unit 7 and the antenna 5 is omitted. The antenna holding part 7 includes a base part 11 and a connector 13 supported by the base part 11. The base portion 11 includes a fixed base portion 15 and a rotation base portion 17 that is rotatably supported with respect to the fixed base portion 15, and the connector 13 is supported by the rotation base portion 17. The base portion of the antenna 5 is attached to the connector 13.

  The base portion 11 includes a base drive mechanism 19 together with the fixed base portion 15 and the rotating base portion 17. The base drive mechanism 19 rotates the rotation base portion 17 between the standing position and the recumbent position with respect to the fixed base 15 in conjunction with an operation on the button 9 as an operation portion. The antenna 5 stands up when the rotating base portion 17 is in the standing position, and the antenna 5 lies down when the rotating base portion 17 is in the lying position.

  The rotating base portion 17 of the base portion 11 is provided with an elastic positioning mechanism 21 that positions the connector 13 at a predetermined set position. The set position is a position perpendicular to the upper surface of the receiver 3 in the present embodiment. The elastic positioning mechanism 21 is a mechanism that applies an elastic force for returning to the set position to the connector 13 rotated from the set position. Therefore, the antenna 5 attached to the connector 13 can fall down when receiving an external force, and can naturally return to the set position when the external force disappears.

  The schematic configuration of the antenna device 3 according to the present embodiment has been described above. Hereinafter, details of the antenna device 3 will be described. In the following description, first, a configuration for supporting the connector 13 in relation to the elastic positioning mechanism 21 will be described. Thereafter, a configuration for raising the rotating base 17 in relation to the base drive mechanism 19 will be described.

  FIG. 3 is an exploded perspective view of the antenna holding unit 7 of the antenna device 3. The rotation base part 17 has a hollow sphere shape, and an upper part of the sphere is omitted. A first control plate 31, a second control plate 33, a connector cover 35, and a connector 13 are inserted into the rotation base portion 17.

  The connector 13 is a BNC connector. An antenna cable (not shown) is connected to the lower portion of the connector 13 so as not to obstruct the rotation of the connector 13, and the cable extends through the hole under the rotation base 17 into the device. The connector 13 has a cylindrical shape as a whole. The lower half of the connector 13 is a supported portion. In the supported portion, the cylindrical surface is cut on both sides in the X direction to form a flat surface. And the projection axis | shaft 37 protrudes in the X direction from each of the planes on both sides. The protruding shaft 37 has a circular cross section. Further, a control projection 39 projects downward from the lower surface of the connector 13. The control protrusion 39 also has a circular cross section.

  The connector cover 35 has a substantially rectangular parallelepiped shape and has a long hole 41 that is long in the Y direction. The connector cover 35 has through holes 43 on both sides in the X direction with the elongated hole 41 interposed therebetween. The connector cover 35 also has through holes 45 on both sides in the Y direction with the elongated hole 41 interposed therebetween. The lower half portion of the connector 13 is fitted in the elongated hole 41 of the connector cover 35, and the protruding shafts 37 on both sides are passed through the through holes 43, whereby the connector 13 is supported to be rotatable in the Y direction. Yes. When the connector 13 rotates in the Y direction, the flat portion of the long hole 41 guides the flat portion of the lower half of the connector 13.

  A gear shaft 51 extending in the Y direction is inserted into the through hole 45 in the Y direction of the connector cover 35. The gear shaft 51 passes through the hole of the rotation base portion 17, passes through the hole of the second control plate 33, and enters the through hole 45. The connector cover 35 is supported by the gear shaft 51 so as to be rotatable in the X direction. As will be described later, the gear shaft 51 is fixed to the rotating base portion 17 and is supported by the fixed base portion 15 so as to be capable of rotating and rotating.

  The connector 13 can rotate in the Y direction around the protrusion shaft 37, and can rotate in the X direction around the gear shaft 51. Therefore, the connector 13 can be rotated so that the antenna 5 is inclined in an arbitrary direction.

  Referring to FIGS. 4 to 6 together with FIG. 3, the first control plate 31 and the second control plate 33 are band-like plates bent so as to form a semicircle. The first control plate 31 and the second control plate 33 are arranged so that the outer surface of the cylinder faces downward. The first control plate 31 and the second control plate 33 intersect each other at an angle of 90 degrees, the cylindrical central axis of the lower first control plate 31 faces the Y direction, and the upper second control plate 33 cylindrical central axes face the X direction.

  The first control plate 31 and the second control plate 33 are supported to be rotatable in the X direction and the Y direction, respectively. More specifically, both end portions of the first control plate 31 are rotatably held in holes of bosses 61 provided on inner surfaces on both sides in the X direction of the rotation base portion 17. Similarly, both end portions of the second control plate 33 are held by bosses 63 on both sides of the rotation base portion 17 in the Y direction.

  The first control plate 31 and the second control plate 33 have rectangular control holes 65 and 67 that are long in the X direction and the Y direction, respectively. As shown in FIG. 5, the control protrusion 39 at the lower end of the connector 13 passes through the control holes 65 and 67. In FIG. 5, the connector 13 is cut by the control protrusion 39, and the connector cover 35 is omitted.

  Next, the control springs 71 and 73 will be described. The control springs 71 and 73 are torsion springs. Each of the control springs 71 and 73 includes a coil portion 75 and first and second end portions 77 and 79 on both sides thereof. The coil portion 75 is a portion where the spring wire is bent into a circle, and the first end 77 and the second end 79 are straight portions at both ends of the spring wire (on both sides of the coil portion 75). The first end 77 and the second end 79 are parallel to each other.

  The control springs 71 and 73 are arranged at right angles to each other. The coil portion 75 of the control spring 71 is fitted to a boss 61 provided on the inner surface of the rotation base portion 17 in the X direction. The coil portion 75 of the control spring 73 is fitted to a boss 63 provided on the inner surface in the Y direction. In both the control springs 71 and 73, the first end 77 and the second end 79 extend downward.

  FIG. 6 is a view of the antenna holding unit 7 of FIGS. 1 and 3 as viewed from the back side. Referring to FIG. 6 together with FIG. 3, the first end 77 and the second end 79 of the control spring 71 pass through the hole of the rotation base portion 17 and engage with the base ribs 81 and 83 of the rotation base portion 17. ing. The first end 77 and the second end 79 are engaged with the bending protrusions 85 and 87 of the first control plate 31. The base ribs 81 and 83 are rod-shaped protrusions that protrude from the rotation base portion 17 in the X direction. The bending protrusions 85 and 87 are rod-shaped protrusions that protrude from the first control plate 31 in the X direction, and are formed by bending a part of the material of the first control plate 31. As shown in FIG. 6, the base ribs 81 and 83 are located outside the first end portions 77 and 79, respectively. Also, the bending projections 85 and 87 are located outside the first end portions 77 and 79, respectively. The base ribs 81 and 83 are located below the bending projections 85 and 87.

  The base ribs 81 and 83 and the bending projections 85 and 87 are also engaged with the other control spring 73 in the same positional relationship. With respect to the control spring 73, the base ribs 81 and 83 and the bending projections 85 and 87 protrude from the rotating base portion 17 and the second control plate 33 in the Y direction.

  The configuration in which the base portion 11 supports the connector 13 has been described above. Next, the operation of the above configuration will be described.

  In the example of FIG. 6, it is assumed that the antenna 5 falls to the right in the Y direction due to an unexpected impact or the like. In this case, the connector 13 rotates clockwise around the protruding shaft 37 as indicated by an imaginary line. Then, the control protrusion 39 at the lower end of the connector 13 pushes the first control plate 31, and the first control plate 31 rotates together with the connector 13 in the clockwise direction. At this time, since the control protrusion 39 moves in the Y direction (longitudinal direction) in the control hole 67 of the second control plate 33, the second control plate 33 does not rotate.

  When the first control plate 31 rotates clockwise, the bending protrusion 85 on the right side of the first control plate 31 pushes the first end 77 of the control spring 71 clockwise from the outside. At this time, the second end 79 of the control spring 73 is supported by the base rib 83 from the left side and does not move. Therefore, the control spring 71 is deformed and a reaction force is generated.

  When the external force on the antenna 5 disappears, the connector 13 and the antenna 5 rotate counterclockwise together with the first control plate 31 by the reaction force of the control spring 71. The control spring 71 returns to its original shape, and the connector 13 and the antenna 5 return to their original set positions.

  The operation when the antenna 5 falls to the left in the Y direction is the opposite of the operation when the antenna 5 falls in the right direction. The principle of operation is the same, and detailed description is omitted. In this case, the second end 79 of the control spring 71 is pushed by the left bending protrusion 87 of the first control plate 31, and the first end 77 is supported by the right base rib 83 of the fixed base portion 17. 71 generates an elastic reaction force in the clockwise direction, and returns the antenna 5 to the original set position.

  The operation when the antenna 5 is tilted in the X direction is also the same as the operation in the Y direction in principle. When the antenna 5 falls in the X direction and the connector 13 rotates in the X direction, the control protrusion 39 of the connector 13 pushes the second control plate 33, and the second control plate 33 rotates together with the connector 13. At this time, since the control protrusion 39 moves in the X direction in the control hole 65 of the first control plate 31, the first control plate 31 does not rotate.

  As the second control plate 32 rotates, the bending projection 85 of the second control plate 32 pushes the first end 77 of the control spring 73, and the base rib 85 of the rotation base portion 17 supports the second end 79. . Alternatively, the bending protrusion 87 presses the second end 79, and the base rib 81 supports the first end 77. Thus, the control spring 73 is deformed to generate a reaction force (restoring force). When the external force on the antenna 5 disappears, the connector 13 and the antenna 5 return to the set position due to the reaction force.

  Thus, in this embodiment, the connector 13 at the base of the antenna 5 is flexibly rotated and restored to the original position when any external force in the X direction or the Y direction is applied to the antenna 5. To do. Therefore, a similar function is obtained with respect to an external force in an arbitrary direction on the XY plane, and the connector 13 is flexibly rotated and naturally returns to the original position.

  The configuration and operation of the flexible support structure of the connector 13 have been described above. Next, the base drive mechanism 19 that realizes the recumbent and standing of the base portion 11 will be described with reference to the side view of FIG. 7 and the plan view of FIG. 8 together with the exploded perspective view of FIG.

  Schematically, the rotation base portion 17 can rotate in the X direction with respect to the fixed base portion 15, and the slide frame 101 can slide in the X direction with respect to the fixed base portion 15. A gear mechanism is provided between the slide frame 101 and the rotation base portion 17. By this gear mechanism, the rotation base portion 15 rotates between the standing position and the recumbent position according to the slide of the slide frame 101. 7 and 8, the antenna 5 and the connector 13 are in the upright position.

  The fixed base portion 15 is a plate-like member, and spring support wall portions 103 and abutting wall portions 105 are provided upright on both sides in the X direction. Further, bearing fixing plates 107 stand on both sides of the fixed base portion 15 in the Y direction. A bearing 109 is fitted in a hole of the bearing fixing plate 107, and the gear shaft 51 is rotatably supported by the bearing 109. And the square flange part of the gear shaft 51 is fitted in the square recessed part of the rotation base part 17, and the gear shaft 51 and the rotation base part 17 rotate together by this.

  As shown in the figure, the rotation base portion 17 is disposed at substantially the center of the fixed base portion 15. The slide frame 101 is placed on the fixed base portion 15 so as to surround the rotation base portion 17. The slide frame 101 can slide in the X direction between the spring support wall portion 103 and the abutting wall portion 105 of the fixed base portion 15. Hereinafter, a direction toward the spring support wall 103 is referred to as a pushing direction, and a direction toward the abutting wall 105 is referred to as a drawing direction.

  Drive gears 111 that are racks are provided on both sides of the slide frame 101 in the Y direction. The drive gear 111 extends in the X direction at the upper end of the slide frame 101. More specifically, a part of the slide frame 101 is raised, and rack teeth are provided at the upper end of the raised part. The drive gear 111 is engaged with the driven gear 113 of the gear shaft 51.

  Two spring holding projections 121 protrude from the end surface of the slide frame 101 in the pushing direction, and a coil spring 123 is fitted to each spring holding projection 121. In the standing state of FIG. 7, the coil spring 123 is sandwiched and contracted between the end surface of the slide frame 101 and the spring support wall portion 103 of the fixed base portion 15. In this state, the slide frame 101 is held by the mini side latch 125.

  Referring to FIG. 9, the mini side latch 125 is a small device that holds the target member A, and is also referred to as a mini side lock. The mini side latch 125 has a lock claw 127 that can be advanced and retracted. When the target member A (slide frame in the present embodiment) advances toward the lock claw 127 of the mini side latch 125, contacts the lock claw 127, and further advances a predetermined distance, the lock claw 127 is lifted, and the target member A Is held (locked). When the target member A is further pushed in from the locked state, the lock is released and the target member A can retreat. When the target member A moves backward, the lock claw 127 follows the target member A by the action of the built-in spring. Then, the lock claw 127 releases the target member A in the middle, falls downward, and returns to the original position.

  Returning to FIG. 7, the mini-side latch 125 is fixed to the fixed base portion 15, and the lock claw 127 is in a locked state. The lock claw 127 passes through the hole of the spring support wall 103 and reaches the end of the slide frame 101 in the pushing direction, and holds the lower end of the slide frame 101. Thereby, the slide frame 101 is held without being pushed back by the coil spring 123.

  On the other hand, at the end of the slide frame 101 in the pull-out direction, the button 9 is provided as follows.

  Two button support walls 131 protrude from the end face of the slide frame 101 in the pull-out direction. A shaft 133 protrudes from the button 9 on both sides in the Y direction. The shaft 133 is fitted in the hole of the button support wall 131. Therefore, the button 9 is connected to the slide frame 101 so as to be swingable up and down.

  A stop protrusion 135 is provided on the fixed base portion 15. The stop protrusion 135 is located in the vicinity of the abutting wall portion 105. In the standing state of FIG. 7, the end of the button 109 is located near the stop protrusion 135. More specifically, a notch 137 is provided at the lower part of the button 109, and a stop protrusion 135 is located below the notch 137. A leaf spring 139 is provided at the end of the slide frame 101 in the pull-out direction. The end of the leaf spring 139 is fitted into the slit of the slide frame 101, and the leaf spring 139 extends in the pull-out direction and presses the button 9 downward. The leaf spring 139 applies a reaction force to the button 9 when the button 9 is rotated upward. Thereby, inadvertent rotation of the leaf spring 139 is prevented. Further, the leaf spring 139 provides an appropriate operational feeling.

  In the above, the structure of the base part 11 was demonstrated centering on the base drive mechanism 19. FIG. Next, the operation of the base drive mechanism 19 will be described.

  First, the operation for raising the antenna 5 and the connector 13 from the lying state will be described. At this time, the rotation base portion 17 rotates from the recumbent position to the standing position.

  In FIG. 7, the revolving base portion 17, the slide frame 101, and the button 9 in the recumbent state are indicated by imaginary lines (two-dot chain lines). In the recumbent state, the slide frame 101 is in the pull-out direction and is pressed against the abutting wall portion 105 by being pushed by the coil spring 123. The button 9 is also retracted in the drawing direction. The rotation base portion 17 is at an angular position such that the connector 13 faces sideways.

  From this state, the button 9 is pushed by the operator. When the button 9 is pressed, the slide frame 101 moves in the pressing direction in conjunction with the button 9. As the slide frame 101 moves, the coil spring 123 is compressed. When the end of the slide frame 101 reaches the mini-side latch 125, the slide frame 101 is gripped by the lock claw 127, whereby the slide frame 101 is locked and held.

  The gear mechanism functions as the slide frame 101 slides. That is, the drive gear 111 rotates the driven gear 113, the gear shaft 51 rotates, and the rotation base part 17 rotates. When the slide frame 101 is locked, the rotation base portion 17 rotates 90 degrees and reaches the standing position. The connector 13 and the antenna 5 also turn 90 degrees and stand up.

  In the standing state, the button 9 is held at a position where it is pushed together with the slide frame 101. A stop protrusion 135 exists in the pushing direction of the button 9. The button 9 is pressed by a leaf spring 139 from above. Therefore, even if an object (including a hand, a finger, etc.) hits the button 9 carelessly, the button 9 is not pushed forward from the standing state. Thereby, an erroneous operation is prevented.

  Next, with reference to FIG. 10 and FIG. 11, the operation when the antenna 5 and the connector 13 are laid down from the standing state will be described. At this time, the rotation base portion 17 rotates from the standing position to the recumbent position.

  In the standing state, the button 9 is held at the position pushed in by the above-described standing operation. In the recumbent action, the button 9 is further pushed by the operator.

  However, as described above, the pushing operation of the button 9 is limited by the stop protrusion 135 and the leaf spring 137. Therefore, as shown by an imaginary line in FIG. 10, the button 9 is lifted upward and then pushed. The leaf spring 137 is deformed, the button 9 is rotated about the shaft 133 and lifted up, gets over the stop protrusion 135 and moves in the pushing direction. Thereby, the slide frame 101 is pushed in a little more than the position of the standing state. The lock claw 127 of the mini side latch 125 is pushed in, and the lock is released. As shown in FIG. 11, the slide frame 101 moves in the pull-out direction by the reaction force of the coil spring 123, hits the abutting wall portion 105, and is held at this position.

  In the above process, in conjunction with the operation of the button 9, the slide frame 101 moves slightly in the pushing direction and then returns to the drawing direction. Along with this, the gear mechanism functions, and the rotation base portion 17 rotates slightly opposite to the recumbent direction as shown by an imaginary line in FIG. 10, and then, as shown by an imaginary line in FIG. Rotates in the recumbent direction. When the slide frame 101 moves to the abutting wall portion 106, the rotation base portion 17 also rotates 90 degrees from the standing position and returns to the original recumbent position. And the connector 13 and the antenna 5 also lie down, and the antenna 5 will be in an accommodation state.

  Here, as shown in FIG. 2, in this embodiment, two antennas 5 stand side by side. The two antennas 5 stand by a predetermined distance that is not more than twice the antenna length. When the buttons 9 on both sides of the receiver 1 are pressed, the two antennas 5 fall toward each other. At this time, when the two antennas 5 come into contact with each other during the fall, the elastic support mechanism (elastic positioning mechanism 21) of the connector 13 functions and the two antennas 5 are slightly inclined in the Y direction (the length of the device). They are perpendicular to the direction and tilted to the opposite side), and fall down while touching each other. Since the antenna 5 has a circular cross section, the two antennas 5 pass smoothly. Then, as shown in FIG. 2, the two antennas 5 face each other and lie side by side. Such an operation is suitably realized by providing an elastic support mechanism (elastic positioning mechanism 21) of the connector 13 in addition to the drive mechanism of the rotation base portion 17 described above. In a simple configuration and arrangement in which the two antenna devices 3 are simply faced, the two antennas 5 can be stored compactly side by side.

  In particular, in the receiver 1 according to the present embodiment, the casing is thin and the size of the casing is limited. And the position of the two antennas 5 for constituting a diversity antenna is also restricted. Specifically, the two antennas 5 are erected along the elongated upper surface of the housing, and more specifically, are erected near both ends of the upper surface. The distance between the two antennas is not more than twice the length of one antenna, and more specifically, is close to the length of one antenna (rather than the length of one antenna). Large predetermined interval). In this case, when trying to lie down on the antenna 5, it is necessary to lie down on the two antennas 5 toward each other. In such a case, the configuration of the present embodiment is very effective. That is, the elastic positioning mechanism 21 preferably functions with a simple configuration in which the antenna holding portion 7 is simply faced, and the two antennas 5 are accommodated in a compact manner.

  Next, FIG. 12 shows a drip-proof structure of the antenna device 3 in the present embodiment. As shown in the figure, a bellows type floating rubber cover 151 is fitted in a groove on the outer periphery of the connector 13. A floating rubber cover 151 fits around a rubber support ring portion 153 provided on the upper portion of the rotation base portion 15 and covers the rotation base portion 15. When the antenna 5 falls and the connector 13 rotates, the floating rubber cover 151 is deformed. The floating rubber cover 151 can prevent water and the like from entering.

  The antenna device 3 according to the embodiment of the present invention has been described above. According to the present embodiment, since the mechanism for elastically positioning the connector 13 to which the antenna 5 is connected to the predetermined set position is provided, the base of the antenna fixing portion can move flexibly. When a load is applied to the antenna 5, the antenna 5 falls down, and when the load disappears, the antenna 5 returns to the set position. Therefore, damage when a load is applied to the antenna 5 due to an unexpected impact or the like can be prevented.

  Further, in the present embodiment, the connector 13 is supported on the base portion 11 by the first rotating shaft and the second rotating shaft that intersect each other. The elastic positioning mechanism 21 includes a first positioning member that rotates together with the connector 13 about the first rotation axis, a second positioning member that rotates together with the connector 13 about the second rotation axis, A first elastic member that imparts to the first positioning member an elastic force that opposes the rotation of the first positioning member, and an elastic force that counters the rotation of the second positioning member to the second positioning member. And a second elastic member to be provided. With such a configuration, the antenna is elastically positioned by a relatively simple configuration in which the antenna is rotatably supported around two axes and an elastic force is provided to counter the rotation around each axis. The mechanism can be realized.

  In the above embodiment, the first control plate 31 and the second control plate 33 correspond to the first positioning member and the second positioning member, and the control springs 71 and 73 correspond to the first elastic member and the second positioning member. It corresponds to the elastic member.

  In the present embodiment, the base drive mechanism 19 rotates the rotation base portion 17 with respect to the fixed base portion 15 between the standing position and the recumbent position in conjunction with the operation on the operation portion. In addition, the labor and time of storage work can be reduced.

  In the present embodiment, a slide frame 101 that slides with respect to the fixed base portion 15 in conjunction with a button operation is provided, and a gear mechanism is provided on the slide frame 101 and the rotation base portion 17 so as to stand upright and lying down. The base drive mechanism 19 can be realized with a relatively simple configuration such as providing a mechanism for holding the slide frame 101. And storage and setting are possible by button operation, and labor and time can be reduced.

  In this embodiment, the antenna can be set and stored with a single operation by pressing a switch type button, and the operation is very simple and quick.

  In the present embodiment, the mini-side latch 125 corresponds to an upright state holding mechanism that holds the slide frame 101 in a state in which the rotary base portion 17 is rotated to the upright position, and the abutting wall portion 105 and the coil spring. 123 constitutes a recumbent state holding mechanism for holding the slide frame 101 in a state where the rotation base portion 17 is rotated to the recumbent position.

  Further, in the present embodiment, two antenna holding portions 7 are arranged for the two antennas 5, and elastic positioning of the drive mechanism 19 and the connector 13 of the rotation base 17 described above is arranged in each antenna holding portion 7. Both the mechanism 21 and the mechanism 21 are provided. Accordingly, as described with reference to FIG. 2, the elastic positioning mechanism 21 acts during the storage operation of the base drive mechanism 19 and changes the direction so that the two antennas naturally pass each other. That is, the two antennas 5 do not stop in a collision, but pass each other after the collision and lie down side by side. Therefore, the two antennas 5 can be stored compactly side by side in spite of a simple configuration in which the two antenna holding portions 7 are simply faced on the electronic device, and the two antennas 5 can be placed in parallel when standing up. Can do. In particular, in a configuration in which two antennas such as diversity are erected side by side on a thin electronic device as in this embodiment, the above compact housing is very effective.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and it goes without saying that those skilled in the art can modify the above-described embodiments within the scope of the present invention.

  As described above, the antenna device according to the present invention has an effect of preventing damage when a load is applied to the antenna due to an unexpected impact or the like, and is useful as an antenna device for a wireless receiver or the like.
