JP4916474B2 - Structure of radiation equipment for 1Seg signal - Google Patents

Description

  The present invention is good even in places where reception conditions are poor and one-seg broadcasting cannot be received (also referred to as dead zones) using mobile terminals (for example, mobile phones, portable electronic dictionaries, etc.). The present invention relates to a structure of a one-seg signal radiating device so that one-seg broadcasting can be received in a state.

In recent years, with the start of 1Seg broadcasting, it has become possible to receive 1Seg broadcasting using a mobile phone. This one-segment service (television broadcasting, various data broadcasting, etc.) is enjoyed by many people.
However, in places such as underground malls and buildings where radio waves do not reach or where reception conditions are poor, the above 1Seg broadcast may not be viewed on a mobile phone (for example, a report by the Ministry of Internal Affairs and Communications on June 21, 2005). (Refer to the document "Holding a study group on the spread of terrestrial broadcasting in radio wave shielding spaces such as underground shopping centers").
Therefore, the improvement is desired.

As an improvement, it is conceivable to prepare a repeater with a minute electric power and retransmit it to an area of a limited area.
However, if re-transmission is attempted in a general household, there may be a problem such as unexpected interference due to interference with an existing broadcast radio wave due to inappropriate use or installation of equipment.

An object of the present application is to provide a structure of a one-seg signal radiating device that can receive a one-seg signal by a mobile terminal and view a one-seg broadcast even in a dead zone.
Another object of the present invention is to provide a structure of a one-seg signal radiating device that does not have an adverse effect on surroundings such as radio wave leakage when a mobile terminal receives a one-seg signal in a dead zone.
Another purpose is to build a one-seg signal radiating device structure that can change the line of sight while keeping the memo paper and the viewing screen at substantially the same height when watching a one-seg broadcast while taking notes on the desk. It is something to be offered.
Other objects and advantages will be readily apparent from the drawings and the following description associated therewith.

  The structure of the one-seg signal radiating device in the present invention is a winding member 10 configured in an elongated bar shape, and a winding surface for winding a sheet-like radiation portion C around the winding member 10. 12, the length W1 in the axial direction of the winding surface 12 for winding the sheet-like radiation portion C is set to a dimension corresponding to the width dimension W2 of the radiation portion, and the sheet-like shape The radiating portion C of the radiating portion C is flexible so that it can be freely wound around the winding surface 12 of the outer periphery of the rod-shaped winding member 10 and deployed on the desk top surface 5. One end 34 on the base side is connected to the winding member 10, and the winding member 10 can be connected to a TV terminal 3 fixed in a house via a power supply line 43. And the sheet-like radiation portion C is provided. In a state where the mobile terminal 7 is deployed on the mobile terminal 7, the one-segment signal from the power feeding unit D is sent to the radiation unit C, and the mobile terminal 7 placed on the radiation unit C is sent to the mobile terminal 7. On the other hand, transmission is performed so that reception is possible from a close range.

  Further, preferably, the winding member 10 is rotatably placed in a coaxial state in a case body 31 formed in a hollow cylindrical shape, and the winding member is disposed on the outer periphery of the cylindrical case body 31. 10 is provided with a narrow insertion port 31b extending in the axial direction of the cylindrical case body 31 for drawing out the sheet-like radiating portion C wound around 10 and allowing it to pass therethrough freely. The opening portions 31c and 31c on both sides of the 31 may be provided with bearing members 33 and 34 for rotatably supporting both sides of the winding member 10.

  As described above, according to the present invention, in the insensitive zone of one-segment broadcasting, when it is desired to receive and view the one-segment broadcasting using the mobile terminal 7, for example, a mobile phone, the sheet-shaped radiation portion C is deployed on the desk. By placing the mobile terminal 7 on the radiating section C, the mobile terminal 7 can receive the one-segment signal from the power feeding section D. Therefore, the one-segment broadcasting is received even in the dead zone. There is an effect on usage that can be viewed.

Moreover, when receiving in the dead zone, the mobile phone 7 is placed on the radiating portion C in the one-seg signal radiating device A, and the radio wave of the one-segment broadcasting is received from the radiating portion C located at a close distance. The signal radiated from C is weak and sufficient.
This can eliminate almost all leakage of radio waves to the periphery, and can eliminate the possibility of adverse effects such as radio wave leakage on the periphery.

  In addition, when a one-segment signal is received by the cellular phone 7, the cellular phone 7 can be used to receive the one-segment signal because the one-segment signal from the radiating portion C can be received simply by placing the cellular phone 7 on the radiating portion C. In some cases, frequent switching operations when the mobile phone 7 is used for an original application (for example, a telephone call) can be quickly performed with one hand.

Further, according to the present invention, since the radiation portion C on which the mobile phone 7 is to be placed is formed in a sheet shape and is not bulky in the height direction (thickness direction), the one-segment broadcasting is viewed on the desk 5 while taking notes. In this case, there is a feature that the mobile phone 7 can be placed at almost the same height as the mobile phone 7 placed directly on the desk.
This has the effect of use that the line of sight can be transferred while keeping the same height between the memo paper and the viewing screen when the information is recorded while watching the one-segment broadcasting.

  Furthermore, the present invention eliminates the need to watch the one-segment broadcasting on the mobile phone 7, and when the desktop 5 is to be used for other paperwork, the radiation portion developed on the desktop 5 is wound around the winding member 10 to form a rod. Can be small. Therefore, there is an effect that the one-seg signal radiating device A is put away at the corner of the desktop 5 and the desktop can be used widely.

Further, according to the present invention, when the one-seg signal radiating device A is in the housed state, the rod-like and small-bulk shape as described above reduces the probability of injury.
Even if added, since the sheet-like radiation portion C is integrated in a rod shape, there is an effect that it can withstand a partial external pressure and can be used with a long life.
