Description of the invention [Technical field to which the invention belongs] The present invention relates to a detachable antenna device used in electronic equipment using an antenna such as a PC card mobile communication device. [Prior art] Generally, an antenna provided in an electronic device having a communication function has an internal antenna form fixedly disposed on a circuit board of the electronic device, and an external antenna form protruding from the outside of the electronic device and capable of telescopic or angle adjustment. The former is suitable for use in places with good radio wave conditions, while the latter is suitable for use in places with poor radio wave conditions. In addition, a communication device such as a conventional PC card type mobile communication device or a mobile phone is provided with an antenna for transmitting and receiving radio waves (see Patent Document 1). The use of the external antenna shown in FIG. The most appropriate antenna position can be obtained by transmitting or receiving the antenna (see Patent Document 2). The external antenna 1 includes a conductive vertical axis 3 that supports the antenna support member 2 and is centered on the vertical axis 3. A conductive intermediate bearing metal member 4 with a shaft rotatably mounted; and a universal joint formed by a horizontal shaft 5 supported on the intermediate bearing metal member 4 orthogonally to the longitudinal axis 3 to hold the antenna support member 2 in action At the same time as the electronic device such as a communication device, the antenna body 6 is rotatably mounted with respect to the intermediate bearing metal member 4 with the horizontal axis 5 as a central axis, so that the antenna body 6 can change directions in accordance with transmission and reception of radio waves. -5- (2) (2) 200406082 However, parts such as the intermediate bearing metal parts 4 constituting such universal joints are formed of conductive metal members in view of strength and the conductive connection between the parts, and the intermediate bearing metal parts 4 The connection portion with the antenna body 6 is in a state in which the metal is peeled off. When the static-charged human body discharges static electricity, there is a risk that the electronic device circuit or the like that conducts the external antenna 1 is destroyed. For this reason, for example, Fig. 14 shows that the metal part of the antenna is covered with a covering material made of an insulating material such as a corrugated tube to form a peeled part, etc., and electrostatic measures are applied. [Patent Document 1] Japanese Patent Laid-Open No. 200 1 -3 3 92 1 (Patent 4) [Patent Document 2] Japanese Patent Laid-Open No. 08_265 025 (Paragraphs 0002 to 0009, Figure 10, (Figure 11) [Summary of the Invention] [Problems to be Solved by the Invention] In the above-mentioned mobile communication device such as a PC card type, a large shape is formed when the external antenna is configured, which is inconvenient to carry. However, when only the internal antenna is used, the sensitivity of the place of use is low, and there are many places where the external antenna is used. In addition, the above-mentioned conventional method for an antenna covered with an external antenna in the form of an insulation is to cover an exposed metal portion with an insulating covering material such as a corrugated tube, which may increase the overall volume of the antenna and prevent the antenna from being mounted. The problem of miniaturization of electronic equipment, as well as problems of antennas and electronic equipment with antennas-(3) (3) 200406082, such as poor appearance. In view of the situation of the above-mentioned conventional technology, the present invention provides a detachable antenna device that can use an internal or external antenna in accordance with radio wave conditions, and can implement a complete electrostatic countermeasure against the antenna, which can be compact and form a detachable type with good appearance. The antenna device is provided for the purpose. [Means for Solving the Problem] In order to solve the above problems and achieve the intended purpose of the invention in the scope of patent application No. 1, the invention is characterized in that it can be disassembled freely from an electronic device with a messaging and / or receiving function, so that The antenna body can be a detachable antenna device composed of a connector device that is electrically connected to an external antenna of an antenna power supply circuit of the electronic device. With the above configuration, the external antenna can be removed when necessary.
