Abstract

A portable terminal apparatus with TV function and a TV antenna with function as an input pen, in which the TV antenna is integrated with the input pen for the touch panel while ensuring sufficient sensitivity so that the internal space of the apparatus is effectively utilized, thus rendering the apparatus smaller and lighter. In the case of using a TV antenna with function as an input pen as an input pen, a mounting operation portion is pushed in a longitudinal direction with a fingertip for pushing it into the apparatus. Thereby, the hold state of the apparatus is released by a function of a latch switch, and the TV antenna with function as an input pen is pushed out to be pulled out of the apparatus. That is, the cellular phone has a configuration in which the TV antenna with function as an input pen cannot be pushed to be detached from the apparatus unless the user contracts a multistage antenna section and houses it completely in a pen body.

Claims

1. A TV antenna with function as an input pen used for a portable terminal apparatus with a display/input section capable of displaying a TV image and receiving an input from a touch panel, comprising:

a contact input portion contacted with the display/input section to provide input; and

a movement lock concavity by which the portable terminal apparatus detachably support the TV antenna with function as an input pen.

2. The TV antenna with function as an input pen according to claim 1, wherein the movement lock concavity locks the longitudinal movement of the TV antenna with function as an input pen so that it does not come off the apparatus.

3. The TV antenna with function as an input pen according to claim 1, including an operational member for allowing the TV antenna with function as an input pen to be pushed into the apparatus when a portion formed of elastically combined conductive materials is contracted.

4. The TV antenna with function as an input pen according to claim 1, further comprising:

a multistage antenna section formed of elastically combined conductive materials, wherein;

the multistage antenna section is at least a part of the TV receiving antenna of the portable terminal apparatus.

5. The TV antenna with function as an input pen according to claim 4, wherein:

the multistage antenna section is configured by concentrically combining a plurality of cylindrical bodies; and

the cylindrical body with the smallest radius in the concentric circles is most distant from the contact input portion while the multistage antenna section is extended, and housed inside the TV antenna with function as an input pen while the multistage antenna section is contracted.

6. The TV antenna with function as an input pen according to claim 5, further comprising an extension preventing section for preventing extension of the multistage antenna section when TV antenna is not mounted on the apparatus.

7. The TV antenna with function as an input pen according to claim 6, wherein the extension preventing section is placed inside the main body of a pen corresponding to the cylindrical body portion of the TV antenna with function as an input pen for housing the multistage antenna section while the multistage antenna section is contracted, and locks the slide movement of the thinnest cylindrical body of the multistage antenna section to lock the slide movement of all the cylindrical bodies configuring the multistage antenna section.

8. The TV antenna with function as an input pen according to claim 6, wherein the extension preventing section is placed inside one of the plurality of cylindrical bodies configuring the multistage antenna section, and locks the slide movement of the thinnest cylindrical body of the multistage antenna section to lock the slide movement of the cylindrical body on the further end side compared to the cylindrical body one step thinner than the cylindrical body having the extension preventing section placed therein.

9. The TV antenna with function as an input pen according to claim 7, wherein the extension preventing section is a plate spring charged to have elastic resilience toward the center in the radial direction of the cylindrical body having the extension preventing section placed therein, and, when subjected to no pressure from the outside, presses the edge against a fixing concavity provided to the thinnest cylindrical body of the multistage antenna section by the resilience to lock the slide movement of the thinnest cylindrical body.

10. The TV antenna with function as an input pen according to claim 9, wherein a lock releasing opening is formed to insert in the apparatus the lock releasing section for, while the TV antenna with function as an input pen is mounted on the apparatus, pressing the plate spring toward the outside in the radial direction of the cylindrical body having the plate spring placed therein.

11. The TV antenna with function as an input pen according to claim 4, wherein the multistage antenna section has an optimal length for receiving VHF when extended to the maximum, and has an optimal length for receiving UHF when contracted to a predetermined length.

12. The TV antenna with function as an input pen according to claim 1, further comprising a bendable hinge freely rotatable with its central axis in the longitudinal direction of the TV antenna at a position exposed outside the apparatus when the TV antenna is mounted on the apparatus and completely extended.

13. The TV antenna with function as an input pen according to claim 12, wherein the hinge is placed at a position moving to the contact input portion when the TV antenna with function as an input pen is expanded and contracted.
