Next, a second embodiment will be described. In the following description, the same reference numerals are given to the same components as those of the television joint receiving device of the first embodiment, and detailed description thereof is omitted.
In this embodiment, as shown in FIGS. 4 and 5, when there are two second connection terminals, a partition shaft shown in FIG. 8 is provided between the drawing holes 2a and 2b formed in the first shaft body 2. In the case where the number of the second connection terminals is three, the body is provided with the partition wall shafts 8 and 9 between 2a, 2b and 2b, 2c. Referring to FIG. 4, when the coaxial cables 6a and 7a are wound around the peripheral surface of the first shaft body 2, the bulkhead shaft body 8 does not come in contact with each other, and the first and second coaxial cables are not in contact with each other.

Details of the TV joint receiving device configured as described above will be described in detail. In the embodiment of the present application, an example in which the first connection terminal 2 is an input terminal and the second connection terminals 6 and 7 are output terminals will be described with reference to FIG.
Signals received by the VHF antenna 21, the UHF antenna 22, and the satellite antenna 23 are mixed via a mixer 24 or an amplifier or the like, and are drawn into the house with a single coaxial cable 25. The drawn signal is distributed by the distributor 26 etc. and then output from the television terminal 27. The duplexer which is the television joint receiving apparatus 1 of the present invention is connected to the television terminal 27 via the coaxial cable 28. This duplexer 1 has an input frequency of, for example, 10 to 2600 MHz, 10 to 770 MHz is output from one of the output terminals, and 1035 to 2600 MHz is output from the other of the output terminals. Thus, the VHF / UHF band signal and the intermediate frequency band signal from the satellite antenna can be demultiplexed from the drawn television signal. Thus, the VHF / UHF band signal is input to the television receiver 30 and the intermediate frequency band signal is input to the satellite tuner 31 or the like.

If there are three output terminals, they are used as, for example, an output terminal for the VHF band, an output terminal for the UHF band (for TV receiver connection), and an output terminal for the UHF band (for tuner connection for digital terrestrial broadcasting). It can also be used as a mixer by using the second connection terminal as an input terminal and using the first connection terminal as an output terminal. Further, it can be used as a branching device and is not limited to the embodiment.
Furthermore, in the embodiment of the present invention, the second connection terminal can be pulled out and wound in the same direction from the insertion holes formed in the side surfaces of the first and second covers. As shown in FIG. 2, when there are two second connection terminals, they may be arranged so as to be opposite to each other by 180 °. For example, when there are three second connection terminals, they are different by 120 degrees. It is not limited to the embodiment such as being arranged, and there is no problem even if it is arranged at an arbitrary position.

Further different embodiments will be described. In this embodiment, the first connection terminal is not provided, and therefore it is not necessary to house an electronic circuit inside the first shaft body. According to this example, the substantially central portion of the coaxial cable having the connection terminals at both ends is penetrated or fixed to the first shaft body by an arbitrary method. Thus, by rotating the second shaft body provided in the first shaft body, the coaxial cable can be wound around or pulled out from the first shaft body.

Thus, like the duplexer shown in the embodiment, according to the television joint receiving apparatus 1 of the present invention, in the case where it is installed behind the television receiver or the satellite tuner in order to demultiplex the signal from the television terminal. However, the length of the coaxial cable can be optimally adjusted according to the arrangement state of the TV, VTR, etc., and a clear wiring can be made on the back of the TV, VTR, etc. In addition, coaxial cables can be stored, and the outer dimensions of the case can be reduced. In addition, it is possible to provide a TV receiver that has the advantage of being compact in the state of shipment and having a low transportation cost.

Note that the present invention is not limited to the above-described embodiment, and the configuration of each part can be appropriately changed and implemented without departing from the spirit of the present invention.
