Embodiments will be described below with reference to the drawings. <A> Outline of Distributor The parallel transmission signal lines are configured in a fixed unit such as eight or sixteen. Therefore, for example, when four signal lines are taken as one block and taken out for each block, the signal lines can be distributed using the distributor 1. As shown in FIGS. 1 and 3, the first to fourth blocks 21 to 24 of the input connectors 2 of the distributors 1, 11 to 13 can connect 16 parallel transmission signal lines A to D. In this case, the four signal lines A are separated from the other signal lines and taken out to the outside via the external output terminal block 4. The remaining twelve signal lines BD are shifted by one block, and
It is connected to three blocks 31-33. When the number of terminals of the input connector 2 and the output connector 3 is the same, the connectors can be shared, and the versatility of the distributor 1 is enhanced. Distributor 1 of FIG.
When the signal lines A to D are inputted, the signal line A can be taken out. On the other hand, in the distributor 10 of FIG. 2, the signal lines A to B can be taken out via the external output terminal block 4 of two blocks. it can. The remaining signal lines C to D are connected to the first and second blocks 31 to 32 of the output connector 3 while being shifted by two blocks. In this way, 16 signal lines can be separated into 8 signal lines.

<B> Connection of distributors The first to fourth four devices 81 to 84 are connected to signal lines A to D, respectively.
Are used, first to third three distributors 11 to 13 are used as shown in FIG. Specifically, the signal lines A to D are connected to the input connector 2 of the first distributor 11. The signal line A is taken out from the external output terminal block 4 of the first distributor 11 and
Connect to device 81. Output connector 3 of first distributor 11
The signal lines BD are taken out of the first to third blocks 31 to 33 of the second distributor 12 and the first to third signal lines of the input connector 2 of the second distributor 12 are extracted.
Connect to blocks 21-23. Similarly, the signal line B is connected to the external output terminal block 4 of the second distributor 12,
It is connected to the second device 82. By repeating these connections, the signal lines C and D are connected to the third and fourth devices 83 and 8 respectively.
4 distributed. As described above, the signal lines A to D can be distributed by simply connecting the same distributor 1 to a plurality of devices, and each of the signal lines can be connected to a plurality of devices 8. Cables for connecting the distributors may have the same shape. As shown in FIG. 4, the first device 85 requiring the signal line A,
A second device 86 requiring signal lines B and C, and a signal line D
In the case where there is a third device 87 which requires the signal lines A to D, the signal lines A to D can be distributed by using the two types of distributors 14 and 15 of the distributor 1 and the distributor 10. Specifically, the signal line A is distributed to the first device 85 by the first distributor 14, and the signal lines B and C are distributed to the second device 8 by the second distributor 15.
6 and the signal line D to the third device 87. Thus, with a similar form of distributor 1 and distributor 10,
Desired signal lines can be arbitrarily and easily distributed.

<C> Common use of distributors Since the distributor 1 and the distributor 10 shown in FIGS. 1 and 2 can be commonly used by one distributor, as shown in FIG. And the output connector 3. The input connector 2 has a plurality of terminals 25 for each block. Similarly, the output connector 3 has a plurality of terminals 35.
, And the external output terminal block 4 also has a plurality of terminals 43. By changing the short-circuit position of the pin of the short-circuit connector 5, the distributor 1 and the distributor 10 can be selected. Specifically, the terminal 25 of the first block 21 of the input connector 2 is connected to the terminal 43 of the first block 41 of the external output terminal block 4. Terminals 25 of the second to fourth blocks 22 to 24 of the input connector 2 are connected to input pins 54 of the first to third blocks 51 to 53 of the short-circuit connector 5, respectively. First to third blocks 51 to 53 of short-circuit connector 5
Of the output connector 3 are the first to third output pins 55, respectively.
Connected to terminals 35 of blocks 31-33. The second output pin 56 of the first block 51 of the short-circuit connector 5 is connected to the terminal 43 of the second block 42 of the external output terminal block 4. The second output pins 56 of the second to third blocks 52 to 53 of the short-circuit connector 5 are connected to the terminals 35 of the first and second blocks 31 to 32 of the output connector 3, respectively. In the distributor 1 wired in this way, when the input pin 54 of the short-circuit connector 5 and the corresponding pin of the first output pin 55 are short-circuited, the distributor 1 of FIG. 1 is obtained. Shorting the corresponding pin of the second output pin 56 results in the distributor 10 of FIG. Therefore, two types of distributors can be easily selected simply by changing the short circuit of the short circuit connector 5.

<D> Specific Example of Distributor The circuit configuration of the distributors 1 and 10 is housed in a case 7.
Input connector 2 and external output terminal block 4 on one side of case 7
The output connector 3 is attached to the other side of the case 7.
Are attached, and these connections are made by circuits printed on the printed circuit board 6. The printed board 6 is arranged on the bottom of the case 7. Distributor 1 only or Distributor 10
In the case of manufacturing only the printed circuit board 6, a predetermined wiring may be provided without the short-circuit connector 5. When the distributor 1 and the distributor 10 are used in common, the short-circuit connector 5 is arranged on the printed circuit board 6, the pins projecting above the short-circuit connector 5 are short-circuited by a predetermined short-circuit member, and the position is changed. Thus, the distributor 1 and the distributor 10 can be selected.
