As shown in FIGS. 11 and 12, for example, six terminal mounting grooves 18 are provided below the modular plug fitting hole 20.
In the four terminal mounting grooves 18 except for the terminal mounting grooves 18 on both sides, the distal ends of the connection terminals 8 are mounted. The connection terminals 8 are connected to the plug terminals 30 of the modular plug 2. When the modular plug 2 on the distal end side of the cord 21 is inserted and fitted into the connector 23, the modem card 1 is connected to a communication line such as a telephone line. Become.

When the modem card 1 is inserted into a personal computer or the like, the connector at the rear end of the card 1 projects from the main body of the personal computer or the like. Because of the thickness, there is a problem that if the thick connector portion 23 protrudes from the apparatus main body, it becomes an obstacle. Also, when moving an apparatus such as a personal computer, the modular plug 2 is detached from the connector section 23 and the modem card 1 is often moved while being inserted into the apparatus. There is a problem that the thick connector portion 23 may hit a desk or the like of a personal computer or the like, which may hinder the modem card 1 or the apparatus body.

Further, when the modem card 1 is manufactured, if the rear end side of the modem card 1 is made thicker to provide the connector portion 23, the material cost is correspondingly increased and the card cost is increased. There were also problems.

In order to solve the above-mentioned problem, for example, as shown in FIG. 6A, a slide receiving hole 9 is provided in the modem card 1 and a slide plate 7 which can be put in and out of the sliding receiving hole 9 is provided. Attach to this slide plate 7,
