[The problem that the idea aims to solve]

By the way, as described with reference to FIG. 12, the present invention provides the adapter 5 in which the size of the connector 5a connected to the connector 4a of the computer 4 is different from the size of the connector 5b connected to the connector 3a of the signal cable 3. And the thirteenth
Although the object is to provide an adapter having a structure similar to that of the adapter 6 described with reference to the figures, the following problem arises.

Referring to FIGS. 12 and 13,
The connectors 8a and 8b shown in FIG. 13 are the same, but
When trying to manufacture an adapter in which the connector 8a is large like the connector 5a shown in the twelfth figure and the connector 8b is small like the connector 5b shown in the twelfth figure, the small-sized connector is like the connector 8b. The connecting rod 13 cannot be used. The flange (code 12b) of the small connector
(see) is narrower than the width between the two connecting rods 13. Therefore, in order to attach the small connector, in addition to both connecting rods 13, a special screw is required to be inserted between the connecting rods 13 and into the flange of the small connector. Furthermore, in order to insert the two dedicated screws in this way, the structure of the adapter 6 becomes complicated, which requires time and effort to assemble, and increases the cost. Incidentally, if the flange of the small connector is made large like the flange 12b of the connector 8b, the connecting rod 1
