Abstract

PROBLEM TO BE SOLVED: To miniaturize an equipment main body by integrating a touch pen with a part of an antenna. SOLUTION: An antenna main body 3 is freely turnably attached to a case 1 so as to adjust the reception sensitivity of this antenna and to easily detach an antenna cap 4. The antenna main body 3 is constituted of a conductor part 3a provided on an axial center and an outer jacket 3b composed of an insulation body for covering the conductor part 3a and is provided with an end part 3A fitted to the antenna cap 4. Since the conductor 3a is covered with the outer jacket 3b of the antenna 3 and the antenna 3 and the antenna cap 4 are completely separated, the performance of the antenna is not changed even when the antenna cap 4 is detached from the antenna 3. The antenna cap 4 is constituted of a hollow conical part 4A fitted to the end part 3A of the antenna 3 and a tip part 4B whose tip is narrowed for pressurizing the surface of a display/input operation part at the tip of the conical part 4A or the like.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable communication information terminal for managing personal information having a wireless communication function and an antenna used for the same.

[0002]

2. Description of the Related Art A portable communication information terminal device has two functions of an electronic organizer for managing personal information and a portable telephone for performing wireless communication. Data communication can be performed only by the information terminal device. In addition, the portable communication information terminal device performs all operations such as calling operation as a fax or a mobile phone, displaying a telephone number, displaying character information as an information terminal, selecting a specific operation, and handwriting input. It can be displayed on the display screen and input by touch pen,
Does not require a numeric keypad for input. Accordingly, the size of the physical device is not restricted by the numeric keypad, so that miniaturization is easy, and operability accompanying the miniaturization can be prevented by touch pen input.

However, the portable communication information terminal device requires both a touch pen for inputting information and an antenna for wireless communication. When the touch pen is stored in the apparatus main body (housing) for loss prevention and convenience, a space for storing both the touch pen and the antenna is required in the apparatus main body, which is an obstacle to downsizing the apparatus main body. Various techniques have been proposed for improving the storage space of the touch pen and the antenna, which is an adverse effect of miniaturization of the device body.

FIG. 5 is a configuration diagram showing a conventional portable communication information terminal device disclosed in Japanese Patent Application Laid-Open No. 7-336759. The conventional mobile communication information terminal device shown in FIG. In the portable communication information terminal device according to the prior art 1, the portable terminal 11 is provided with a detachable antenna / input pen 12 connection mechanism 18, and the antenna / input pen 12 is used as a wireless antenna when inserted into the connection mechanism 18. When the antenna / input pen 12 is pulled out of the connection mechanism 18, it is also used as an input pen for writing handwritten characters or numbers.

[0005] With this configuration, the antenna always functions as an antenna while being inserted into the connection mechanism 18, and is automatically switched to an internal antenna by taking out at the time of an incoming or outgoing call to make a calling state. The extracted antenna / input pen 12 can also be used as handwritten character / number input means as it is, and no space is required in the portable terminal 11 for accommodating both the touch pen and the antenna, thereby reducing the size of the main body. Becomes possible. However, since the antenna / input pen 12 including a conductor is configured to be separated from the portable terminal 11, in order to maintain the reception function when the antenna / input pen 12 is used as a touch pen, the internal antenna and its A changeover switch structure is required.

FIG. 6 is a block diagram showing a conventional portable communication information terminal device disclosed in Japanese Patent Application Laid-Open No. 7-311737. The conventional portable communication information terminal device shown in FIG. In the portable communication information terminal device shown in FIG. 6, a pen-shaped conductor 21 functioning as an antenna and also functioning as a touch pen is detachably attached to a pen insertion hole 22. When the pen-shaped conductor 21 is attached to the pen insertion hole 22, the pen-shaped conductor 21 and the wireless communication module 23 are electrically connected via the connection terminal 24, and the pen-shaped conductor 21 functions as an antenna. I do. When a pen touch input is performed on the touch screen with the pen-type conductor 21, the pen-type conductor 21 is not attached to the pen insertion hole 22, and functions as a data input pen.

[0007] With this configuration, the pen-type conductor 21 functioning as a data input pen or the like can function as an antenna simply by being inserted into the pen insertion hole 22 if necessary. At times, it is possible to reduce the number of parts and reduce the size and price without getting in the way. However, when the pen-type conductor 21 functions (uses) as a touch pen, it cannot function (use) as an antenna, and the pen insertion hole 22 for allowing the pen-type conductor 21 to function as an antenna. Is also required.
