Embodiments of the present invention will be described below. FIG. 1 shows an example of the embodiment of the second aspect of the present invention, in which a horizontally elongated slot-shaped insertion port 3 is provided on the front surface of a housing 24 of the terminal device 1. The card insertion portion 20 is formed as shown in FIG. An eject button 11 is provided near the side of the insertion slot 3 in the longitudinal direction. The ejection button 11 is used to insert the memory card 2 into the card insertion portion 20 from the insertion slot 3 and to connect a terminal at the tip of the memory card. When the electrode pin 21 is inserted into and connected to an insertion hole (not shown) of the portion, the terminal pin 1 projects largely from the front surface of the housing 24 of the terminal 1.

The card cover 4 is formed of a transparent resin molded product such as an acrylic resin into a semicircular shape having a vertical section with an open back side. One side end is closed by a side plate 25 and the other side end is an opening 5. There is. This card cover 4
A hook-shaped slide locking piece 26 is integrally formed on the rear surface of the upper end and the lower surface of the lower end. In addition, on the front surface of the housing 24 of the terminal 1, on the upper side and the lower side of the outlet 3 and the eject button 11, the position of the outlet 3
A slide groove 27 having an L-shaped cross section reaching the side position of the groove is recessed, and the slide locking piece 26 is slidably locked in the slide groove 27 as shown in FIG.
The card cover 4 is attached to the front of the housing 24 of the terminal 1. The card cover 4 can be slid along the slide groove 27 between a position on the side of the insertion port 3 and a position covering the insertion port 3 and the eject button 11.

In this embodiment, the card cover 4 is slid to the side of the insertion slot 3 as shown in FIG. When the card cover 4 is slid and moved to a position covering the insertion slot 3 and the eject button 11 as shown in FIG. 1B, the card cover 4 is inserted into the insertion slot 3. The end protruding from the insertion slot 3 of the memory card 2 can be covered with a card cover 4, and at this time, the protruding tip of the memory card 2 inserted into the insertion slot 3 as shown in FIG. It is not necessary to abut the inner surface of the cover 4, but the card may be inserted in the terminal portion of the memory card 2 so that the insertion hole does not come off from the electrode pin 21 even when the memory card 2 moves in the direction of coming out of the insertion slot 3. Memory card 2 to the inner surface of the cover 4
It is necessary that the protruding tip of the memory card 2 is close to the inner surface of the card cover 4 so that the protruding tip of the memory card 2 comes into contact with the card cover 4.

Therefore, in a state where the end protruding from the insertion port 3 of the memory card 2 is covered with the card cover 4 as described above, the memory card 2 comes out of the insertion port 3 even if the vibration or the like acts on the terminal 1. The movement in the direction can be restricted by the card cover 4, and it is possible to reliably prevent the insertion hole of the terminal portion of the memory card 2 from coming off from the electrode pin 21 and to improve the connection reliability. At this time, since the eject button 11 is also covered with the card cover 4, it is possible to prevent an accident such that the eject button 11 is pressed carelessly and the memory card 2 is removed.

When removing the memory card 2 from the terminal 1, the card cover 4 is slid to a position beside the insertion slot 3 so that the memory card 2 and the eject button 11 are connected as shown in FIG. 4, the memory card 2 is pulled out from the insertion slot 3 by pressing the eject button 11.

FIG. 2 shows an embodiment of the third aspect of the present invention. A holding rib 6 is provided on the inner surface of the card cover 4 so as to protrude. The pressing rib 6 is formed in a wedge shape such that the protruding dimension is small at the end of the card cover 4 on the opening 5 side, and the protruding dimension is larger at the end opposite to the opening 5. Other configurations are the same as those shown in FIG.

In this case, as in the case of FIG. 1 (a), with the card cover 4 slid to the side of the insertion slot 3, the memory card 2 is inserted into the insertion slot 3 and the terminal is inserted.

According to the eleventh aspect of the present invention, a leaf spring is attached to the inner surface of the card cover, and the leaf spring is applied to the end of the memory card protruding from the insertion port while rotating the card cover so as to cover the insertion port. Because it can be freely connected, even if vibrations etc. act on the terminal, the memory card can be prevented from moving in the direction of coming out of the insertion slot by pressing it with a leaf spring, and the connection reliability of the memory card to the terminal can be improved. It can be enhanced.

According to a twelfth aspect of the present invention, there is provided a memory card having a resilient spring piece integrally provided on an inner surface of a card cover and projecting from the insertion slot with the card cover rotated so as to cover the insertion slot. The spring piece can be freely abutted on the tip, so that even if vibrations etc. act on the terminal, the memory card can be prevented from moving in the direction of coming out of the insertion slot by pressing it with the spring piece. The connection reliability of the card can be improved.
