Description

DETAILED DESCRIPTION OF THE INVENTION 4KIH relates to the distribution of wideband signals such as television signals, combination L-p color data signals or analog or digitized output signals from measuring devices.

%. According to the distribution device κ of the present invention, each input signal source κ can be connected to the selected input signal OIt output without interference, interference, etc. κ and with input loss tjl kept to a minimum.

The figure is an electrical circuit diagram of a distribution device according to an embodiment of the present invention,
10 to 18 are input terminals, and 20 and ρ are output terminals.

Terminal 10 is designated as the antenna (ANT) input terminal, terminal 12 is designated as the cable television (CATV) input terminal, and terminal 14.16 is the auxiliary (AUX) input terminal.
The terminal l8 is designated as an input terminal for receiving the output of an external video recorder (VTR). One of the two output terminals (22) is designated as an output terminal for an external video recorder (VTR), and the output terminal η is designated as an output terminal for a monitor television (1"V). .Auxiliary as mentioned above (
AUX) Input terminals 14 and 16 are for output from a video disc.

Output from video games, output from computers, #
The output from the constant device is connected to this terminal.

In the embodiment shown there are two hand-switches 8W-1 and 8.
W-2 is provided. These switches are conventional rotary switches.

The first switch 8W-1 is a 5-circuit 4-contact Jetty Φ switch as shown in 8W-1~5W-1eK, and the switch 8W-2 of aiL2 is 8W-2J1~8W.
-2eK As shown, the rotary switch has 5 circuits and points sm, and in the switch position shown in figure 0, the input terminal lO
The configuration is such that the ANT input of is applied to the VTR output and TVV power 22. As mentioned later, VTR
Switching of input to output is done by gl switch 8W-IK.

Switching of the input to the TV output is performed by the second switch 8W-2. By selecting these various switch positions, additional human power can be selectively applied to two outputs, 22.

26, 28, and 30 are input terminals 10, 12, respectively.
．． This is a coupler related to 14.degree.

(1) In this embodiment, the input terminals 18 are connected in such a way that they are applied only to the TV monitor output terminal n by selection of the second switch.

The couplers 24, 26, 28, 30 are arranged to couple 5-band signals, such as television signals, without adversely affecting the human power source and the equipment connected to the two distributed outputs. For example, C A 'r connected to input terminal 12
The V signal is connected to the VTR output terminal and the TV by the coupler 26.
However, the operation of the equipment connected to the meat output is not affected, and since both outputs are used, the human power signal source is not affected.

v 'I' First switch 8W- associated with R output addition
1 has 4 contacts in each circuit, and 1 from the top in the figure.
, 2, 3.4 are numbered. Contact 1 is input 1 of wire 1
0, contact 2 relates to the second input 12, contact 3
is related to the third human power 14, and the contact point 4 is related to the third human power 16v
c related. That is, inputs 10, 12, 14, and 16 are selectively applied to output 2DK at positions of contacts 1 and 2°3.4, respectively. Similarly, the switch 8W-2 of IK2 has five contacts s, 2, 3, 4.51', and in the contact l position A
The NT input 10 is connected to the second output 22, and in the position of contact 2 the CATV input 12 of the cable 2 is connected to the output 22;
At the position of contact point 3, input 14 of line 3 is 1MI, and at position of point 4, input 16 of 1!4.

At contact 5, VTR input 18 is connected to output 22.

Therefore, the functions of the dispensing device of the present invention having one or more configurations can be summarized as follows.

(1) Human power shall be distributed among at least 10,000 of the two outputs.

(2) The two outputs can be selectively connected to any of a number of inputs.

(3) Transmission loss between input and output must be the lowest on the market.

(4) There is no interference or disturbance between each human signal source.

(5) Even if one human power is distributed to two outputs at the same time, no disturbance will occur.

(6) Since one input changeover switch is provided corresponding to each output, it is easy to confirm which input and output are selected, and the configuration of the indicating function is easy.
