  Nowadays, the card adapter device is required to be smaller. However, even if the card adapter device is miniaturized as described above, there is a demand for setting the length of the card to a relatively long size within a range in which the card adapter device can be mounted. In the prior art described above, the contact portion of each card contact terminal connected to the card is located on the side away from each external connection terminal as described above. The length dimension is shortened, and the demand for setting the length dimension as described above to be long cannot be satisfied.

  In this case, it is conceivable that the length of each card contact terminal is shortened, the contact portions of these card contact terminals are brought closer to each external connection terminal, and thereby the length of the card is set longer. However, with such a configuration, as the length of each card contact terminal becomes shorter, the spring characteristics of these card contact terminals deteriorate, and good contact is made between these card contact terminals and the card. The pressure cannot be secured, causing a problem that the reliability of the apparatus is lowered.
