Is provided. A lower end portion extending continuously downward from the hook claw 16 is rotatably connected to an upper end portion of the support member 20 via a pin 22, and the hook claw 16 is further rotated counterclockwise in the drawing. A helical spring 24 (constituent member) made of a metal (conductor) material that is energized as described above is provided around the pin 22.

  The case 12a, the support member 20, and the fulcrum pin 22 of the charging device 12 are formed of a material (plastic or the like) other than the conductor.

  A button 32 is arranged on the left side (near the center) in the drawing from the hook claw 16 of the charging device 12 so as to protrude upward from a hole 37a formed in the bottom plate 37 of the inner concave portion 14, and this button 32 is arranged. The operation part 36 a of the safety switch 36 mounted on the circuit board 34 is arranged below the circuit board 34. The safety switch 36 is made of a metal conductor such as a spring as a constituent member.

  In FIG. 5, the charging terminal 38 is arranged on the side of the main body fixing rib 28 from the center in the left-right direction of the charging device 12 at a position where it can be seen through a hole 37 b in the bottom plate 37 of the inner recess 14. Is mounted on the circuit board 34 so that power can be supplied.

  The circuit board 34 is supported at the center in the left-right direction in FIG. 5 via a fulcrum pin 46 so that both ends of the circuit board 34 can alternately swing in the vertical direction, and the right end of the circuit board 34 in the figure is The pressing spring 40 is always urged upward.

  Further, the charging device 12 is provided with a locking member 42 that is locked to the right end portion of the circuit board 34 in FIG. 5, and the locking member 42 is locked to the right end portion of the circuit board 34 in FIG. 5. Thus, the operating portion 36a is pressed by the pressing force of the pressing spring 40 and the reaction force of the button 32 (bottom plate 37), thereby preventing the safety switch 36 from being always turned on.

  When the mobile phone 10 is mounted on such a charging device 12, as shown in FIG. 6, first, the fixing rib 28 of the charging device 12 is inserted into the rib hole 30 of the mobile phone 10 while the mobile phone 10 is inclined. To do.

  Then, as shown in FIG. 7, the hook claw 16 of the charging device 12 is locked in the hook hole 18 of the mobile phone 10. At this time, the hook claw 16 is pushed by the case of the mobile phone 10 immediately before being locked in the hook hole 18, and is slightly rotated in the clockwise direction against the helical spring 24, so that the hook hole 18 is lowered. Then, when it coincides with this position, it is urged counterclockwise by the helical spring 24 and is fitted into the hook hole 18 to be locked.

  When the mobile phone 10 is thus attached to the charging device 12, the button 32 is pressed by the bottom surface of the case of the mobile phone 10 and descends, the operation part 36 a is pressed to turn on the safety switch 36, and the fulcrum pin 46 is turned on. As the circuit board 34 swings, the charging terminal 38 rises and comes into contact with the exposed charging terminal 44 of the storage battery in the mobile phone 10 so that the charging device 12 can start the charging operation. Yes.

  By the way, when the safety switch 36 (conductive device) is OFF, no current flows through the charging terminal 38, so that it is in a safe state. When the safety switch 36 is ON, the charging terminal 38 A current flows (conducts), and the charging device 12 is in a state in which the charging operation can be performed.

  However, in such a combination of the conventional mobile phone 10 and the charging device 12, when the mobile phone 10 is attached to the charging device 12 during charging, a metal helical spring 24 is provided in the vicinity of the built-in antenna 26. Therefore, when wireless communication is performed during charging, the electromagnetic electromagnetic wave is disturbed by the metal helical spring 24, and the communication performance of the built-in antenna 26 is hindered, thereby adversely affecting the communication. There was a problem.

  Therefore, in view of the above problems, the present invention provides a combination of a portable communication device and a charging device that can maintain a good communication state with an antenna even during charging with the portable communication device attached to the charging device. The challenge is to provide a body.

In order to solve the above problems, the present invention
A combination of a portable communication device and a charging device,
In a state where the portable communication device is attached to the charging device,
A member formed of a conductor material is not arranged in the region of the charging device included in a range of 5 mm around the antenna unit of the portable communication device.
More preferably, a member formed of a conductor material is not disposed in the region of the charging device included in a range of 2 mm around the antenna portion.

  Further, the portable communication device is characterized in that the antenna is arranged in a casing of the portable communication device.

  Further, the conductor is a constituent member of at least one of a positioning device and a conductive device.

  According to the combination of the portable communication device and the charging device having such a configuration, it is possible to maintain a good communication state with the antenna even during charging with the portable communication device attached to the charging device.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
1 to 3 are diagrams which are referred to for explaining an embodiment of a combination of a portable communication device and a charging device according to the present invention. The same parts as those in the prior art will be described with the same reference numerals, and redundant description of the same configuration as in the prior art shall be omitted.

FIG. 1 is a diagram showing a state where mobile phones 10 (mobile communication devices) according to an embodiment of the present invention are separated from each other before being mounted in the inner concave portion 14 of the charging device 52.
The mobile phone 10 shown in the figure has the same configuration as that of the conventional mobile phone 10, but the charging device 52 is different from the conventional charging device 12 as will be described below. have.

  Whereas the hook claw 16 of the conventional charging device 12 is simply formed to extend straight to its lower end, the hook claw 56 of the charging device 52 in the present embodiment is as shown in FIG. Not only is it formed to extend straight to its lower end, but also differs in that it is formed in an L shape provided with an arm portion 56a that bends and extends 90 ° from its lower end.

  The 90-degree bent portion of the L-shaped hook claw 56 is supported by the support member 20 via the fulcrum pin 22 so as to be rotatable. And the front-end | tip part of the arm part 56a of the hook nail | claw 56 is always pressed below by the press coil spring 54 (conductor) provided in the back surface (lower surface) side of the bottom plate 37 of the inner side recessed part 14 of the charging device 52. .

Further, the hook hole 18, the support member 20, the fulcrum pin 22, and the hook claw 56 constitute a positioning device for the mobile phone 10 in the charging device 52.
Further, the case 52a of the charging device 52, the hook claw 56 having the arm portion 56a, the support member 20, and the fulcrum pin 22 are formed of a material (plastic or the like) other than the conductor.

  When the mobile phone 10 is attached to such a charging device 52, the procedure is the same as the conventional one. First, as shown in FIG. 2, the fixing rib 28 of the charging device 52 is inserted into the rib hole 30 of the mobile phone 10. Then, the mobile phone 10 is inserted while being inclined.

  Then, as shown in FIG. 3, the hook claw 56 of the charging device 52 is locked in the hook hole 18 of the mobile phone 10. At this time, the hook claw 56 is pushed by the case of the mobile phone 10 immediately before engaging with the hook hole 18, and slightly rotates clockwise against the pressing coil spring 54, and the hook hole 18 is lowered. When the position coincides with the position, the coil spring 56 is urged by the pressing coil spring 54 to rotate counterclockwise, and the hook claw 56 is fitted into the hook hole 18 to be engaged therewith.

  According to such a combination of the mobile phone 10 and the charging device 52, as shown in FIG. 3, when the mobile phone 10 is attached to the charging device 52, the end of the charging device 52 on the hook claw 56 side and the pressing portion are pressed. All members such as the hook claw 56, the support member 20, the fulcrum pin 22, and the case 52a of the charging device 52, which are in the conductor prohibited region E between the coil spring 54, are made of a material other than the conductor (plastic or the like). Only what is formed is placed.

  For this reason, the communication electromagnetic wave is not disturbed by the conductor during wireless communication during charging by mounting the mobile phone 10 on the charging device 52, so that even when the mobile phone 10 is charged by the charging device 52, it is built-in. A good communication state by the antenna 26 can be maintained.

  That is, the distance between the built-in antenna 26 and the pressing coil spring 54 is set to be larger than the distance between the built-in antenna 26 and the coil spring 24 in the conventional combination of the mobile phone 10 and the charging device 12. Incidentally, it is preferable that the built-in antenna 26 and the conductor such as the pressing coil spring 54 are separated by 5 mm or more.

  In the above-described embodiment, the case where the mobile phone 10 is provided with the built-in antenna 26 has been described. However, the antenna is not limited to the built-in antenna, and an antenna exposed to the outside of the mobile phone 10 is used. The present invention can also be applied to a portable communication device.

  In the above embodiment, the case where the pressing coil spring 54 is separated from the built-in antenna 26 by 5 mm or more has been described. However, it is needless to say that the safety switch 36 (conductive device) should be separated from the built-in antenna 26 by 5 mm or more. Absent. This is because a metal conductor member such as a spring is also used for the safety switch 36.

  Further, in the embodiment, for the sake of easy understanding, when the button 32 is pushed into the bottom surface of the mobile phone 10 and retracted, the circuit board 34 swings in a seesaw shape via the fulcrum pin 46, and the charging terminal The configuration in which 38 protrudes outward and contacts the exposed terminal portion 44 has been described, but the circuit board 34 does not necessarily have to swing, and if the charging terminal 38 can protrude outward when the button 32 is retracted, It goes without saying that any other configuration may be used.

  Moreover, in the said embodiment, although the mobile telephone 10 was demonstrated as a portable communication apparatus with a transmission output of about 200-800 mW, the portable communication apparatus which concerns on this invention does not need to be limited to a mobile telephone, It is the same as that of this invention. The present invention can also be applied to other portable communication devices such as PDA (Personal Digital Assistant) as long as the above-described effects can be obtained.
