A card mounting apparatus according to the invention comprises a housing having a card chamber into which a card is inserted through an opening, and a card holder having a card facing surface and accommodated in the card chamber, the card holder adapted to be moved forward from the opening to be outside of the housing as well as backward to be inside of the housing again. The housing comprises projected parts extending from an inner wall which defines the card chamber, into the card chamber, wherein the card holder comprises a pull tab which is exposed from the opening of the housing, on one end, a card engagement part contacting with the card and moving it forward by a forward movement of the card holder on the other end opposite to the end with the pull tab and a guide extending in a direction of the forward and backward movements of the card holder. The projected parts of the housing engage with the guide to guide the forward and backward movement of the card holder.

ADVANTAGEOUS EFFECTS ON INVENTION

In the card mounting apparatus of the present invention, the housing has the card chamber into which the card is inserted through the opening, and the projected parts extending from the inner wall, which defines the card chamber, into the card chamber; and a card holder comprises a card facing surface and is accommodated in the card chamber, the card holder being able to be moved forward through the opening from the housing as well as backward into the housing again. The card holder further comprises a pull tab on one end, which is exposed from the opening of the housing, a card engagement part contacting with the card and moving it forward by a forward movement of the card holder on the other end opposite to the end with the pull tab, and a guide extending in a direction of the forward and backward movement of the card holder. The projected parts of the housing engage with the guide to guide the forward and backward movements of the card holder. Thereby, upon insertion of a card, the card is moved and inserted into the card chamber with the card holder from the opening of the housing by sliding the card along the card facing surface of the card holder which is either moved backward into the card chamber, or moved forward from the card chamber. Upon removing a card, if the card holder is moved forward from the card chamber through the opening of the housing by pulling the pull tab, the card engagement part engages with the card held on the card facing surface and moves it forward, and thereby the card is removed from the card chamber through the opening of the housing.

Further, if the card holder is moved forward or backward, the projected parts extending from the inner wall of the card chamber of the housing into the card chamber engage with a guide extending in a direction of forward and backward movements of the card holder, and guide the forward and backward movements of the card holder. Upon insertion of a card, if the card is about to be inserted into the card chamber from the opening of the housing along a surface opposite to the card facing surface of the card holder, the card is contacted with the projected parts projecting into the card chamber and a further insertion of the card is reliably prevented.

With the card mounting apparatus of this invention, upon insertion of a card, if the card is about to be inserted on the opposite surface side instead of the card facing surface, it is ensured that a wrong insertion and damaging of a card or a card holder can be inhibited beforehand.

The UIM drawer 12 forms a plate like shape having a cross section with approximate U shape and a card holding surface (a card facing surface) on one surface (lower surface in FIG. 1 and FIG. 5), and is disposed between a back surface of the rear case 3b and a metal plate 13b of a card holder 13, so that it can slide between a backward position inside of the housing as shown in FIG. 1(a) and a forward position outside of the housing as shown in FIG. 1(b). The card holder 13 is implemented on the circuit board 6, for example, by means of soldering and the like, and comprises an inlet 13c between the connector 13a and the metal plate 13b, into which the UIM card 11 held on the card holding surface 12a of the UIM drawer 12 can be inserted in a direction of the opening 3e of the character input side housing 3. The UIM card 11 has a memory means storing information and a terminal face (exposed face) on the surface of the UIM card 11 which is electrically connected to the memory means. As shown in FIG. 1(a), a spring terminal 13d of the connecter 13a is held on a card holding face 12a of the UIM drawer 12 which is moved backward to a predetermined position, and is located in a predetermined inserted position within the card chamber 3f, resiliently deforming and resting against a terminal face (not shown) of the UIM card 11 located in the card holder 13, and is electrically contacted with the terminal face.

The card mounting apparatus 10 of this exemplary embodiment is further described now with reference to the accompanying drawings. FIG. 6 is a perspective view of the fold type cellular phone from the rear case side showing the character input side housing without the rear case 3b; FIG. 7 is a perspective view of the fold type cellular phone showing the character input side housing 3 without the UIM drawer 12; FIG. 8 is a perspective view of a UIM drawer 12 of the card mounting apparatus 10 in the embodiment described above in the same orientation shown in FIG. 6; FIG. 9 is a plan view of the rear case 3b of the character input side housing 3 in the card mounting apparatus 10 according to the embodiment above from the back side; FIG. 10(a) is a perspective view of the UIM drawer moved backward and FIG. 10(a) is a perspective view of the UIM drawer moved backward and FIG. 10(b) is a perspective view of the UIM drawer moved forward, engaging with a projection of the rear case, respectively, viewing from the back side of the rear case; FIG. 11 is a perspective view of the character input side housing 3 of the fold type cellular phone with the UIM drawer 12 moved forward and the UIM card 11 removed.

As shown in FIG. 8 and FIG. 1, the UIM drawer 12 comprises on one end (on the left end in FIG. 1) thereof, a pull tab 12b which is exposed from the opening 3e and forms a projection extending from the opposite face of a card holding face 12a, and a card engagement part 12c projecting from the card holding face 12a on the other end (on the right end in FIG. 1) opposite to the end with the pull tab 12b. As shown in FIG. 1(b), the card engagement part 12c is contacted with a UIM card 11 held on the card holding face 12a and the card is moved forward by a forward movement of the UIM drawer 12 through the opening 3e of the character input side housing 3.

In addition, as shown in FIG. 8, the UIM drawer 12 comprises a fitting part 12d projecting from the card holding face 12a on both sides in a direction traverse to a direction of the forward and backward movements (a right and left direction in FIG. 2), that is a direction connecting a pull tab 12b with the card engagement part 12c, and extending in a direction of forward and backward movements, thereby forming a cross section with approximate U shape as described above. Both sides of the card holder 13 are fitted between the fitting parts 12d. As shown in FIG. 8, two elongated guide holes 12e as a guide are formed in a flat part of the UIM drawer 12 surrounded by a pull tab 12b, the card engagement part 12c and fitting parts 12d on both traverse sides and extends in a direction of forward and backward movements. As shown in FIG. 1, the flat part closer to the pull tub 12b rather than to the elongated guide holes 12e is reduced its thickness and formed as an insertion part, and thereby forming an inclination on the side of the card holding face 12a to the pull tab 12b in order to facilitate an insertion of the UIM card 11. Further, a thick part compared to other portions of the flat part near the pull tab 12b is formed on a portion of the flat part which is located opposite to the spring terminal 13d when the UIM drawer 12 is moved backward to a predetermined position.

As shown in FIG. 1 and FIG. 10, two projected parts 3g are formed on the back side of the rear case 3b of the character input side housing 3, opposite to the spring terminal 13d on a connector 13a of the card holder 13 and adjacent to an end part of the metal plate 13b on the side of the inlet 13c. The projected parts 3g engage with the two elongated guide holes 12e of the UIM drawer 12 and guide forward and backward movements of the UIM drawer 12, as shown in FIGS. 10(a) and (b). The projected parts 3g has a U shape, viewing from the front face, as shown in FIG. 9, in order to prevent a sink mark on the surface of the rear case 3b and ensure the rigidity of the projected parts, and so that the corresponding elongated holes 12e are not too narrow to be molded. As shown in FIG. 1, the projected parts 3g projects slightly from the card holding face 12a through the elongated holes 12e, and end faces of the projected parts 3g are coplanar with the back side of the metal plate 13b and smoothly connected with it. The projected parts 3g do not necessarily have to project from the card holding face 12a through the elongated holes 12e.

In this card mounting apparatus 10 according to this embodiment, the character input side housing 3 comprises the card chamber 3f into which a card is inserted through the opening 3e, and the projected parts 3g extending from the inner wall of the card chamber 3f into the card chamber 3f. The UIM drawer 12 comprises the card holding face 12a and is accommodated in the card chamber 3f, so that the UIM drawer 12 can be moved forward and backward. The UIM drawer 12 further comprises a pull tab 12b on one end, which is exposed from the opening 3e, and on the other end opposite to the end with the pull tab, the card engagement part 12c which engages with the UIM card 11 held on the card holding face 12a and moves the UIM card 11 forward by a forward movement of the UIM drawer 12 through the opening 3e. The UIM drawer 12 further comprises the elongated holes 12e extending on the opposite side of the card holding face 12a in a direction of the forward and backward movements of the UIM drawer 12. The projected parts 3g are contacted with the elongated guide holes 12e and guide the forward and backward movements of the UIM drawer 12, cooperating with the fitting structure of the fitting parts 12d of the UIM drawer 12 and both sides of the card holder 13.

By the structure described above, upon insertion of an UIM card, the UIM card 11 is inserted by sliding it along the card holding face 12a of the UIM drawer 12 which is retained in a backward position in the card chamber 3f, or the UIM card 11 is inserted by moving it along the card holding face 12a of the UIM drawer 12 which is moved forward from the card chamber 3f. Thereby, the UIM card 11 is inserted into the card chamber 3f through the opening 3; as shown in FIG. 1(a) and FIG. 2. In order to remove the UIM card 11, UIM drawer 12 is moved forward from the card chamber 3f through the opening 3e by pulling the pull tab 12b exposed from the opening 3e open to the battery receiver 3c of the character input side housing 3, with the battery cover 9 and the battery being eliminated. Then the card engagement part 12c engages with the UIM card 11 held on the card holding face 12a, and moves the UIM card 11 forward, which is then pulled out of the opening 3e and removed from the card chamber 3f.

With the card mounting apparatus 10 according to this embodiment, as shown in perspective view in FIG. 12(a) as well as in cross section in FIG. 12(b), if the UIM card 11 is about to be inserted into the card chamber 3f from the opening 3e open to the battery receiver 3c of the character input side housing 3 along the face opposite to the card holding face 12a of the UIM drawer 12 by mistake, the UIM card 11 is contacted with the projected parts 3g projecting into the card chamber 3f from the inner wall of the card chamber 3f of the character input side housing 3, so that a further insertion of the UIM card 11 is reliably prevented. Thus, with the card mounting apparatus 10 according to this embodiment, if the UIM card is about to be inserted on the opposite side (lower side) by mistake instead of the card receiving face 12a side, a wrong insertion of the UIM card can be reliably prevented and damaging of the UIM card 11 or the UIM drawer 12 due to the wrong insertion can be inhibited beforehand.

With the card mounting apparatus 10 according to this embodiment, a terminal face of the UIM card 11 is contacted and electrically connected with a spring terminal 13d on the connector 13a in a predetermined position in which the UIM card 11 is moved backward with the UIM drawer 12. Then, the spring terminal 13d deforms resiliently and pushes the UIM card 11, so that the electric connection is maintained in a more suitable way. In the card mounting apparatus 10 according to this embodiment, the projected parts 3g of the character input side housing 3 run through the elongated guide holes 12e of the UIM drawer 12, and are formed higher than the thickness of the circumference of the elongated guide holes 12e in the UIM drawer 12, thereby, projecting from the surrounding card holding face 12a and guiding the UIM card 11 in card chamber 3f by contacting with the UIM card 11 in a sliding way, as shown in FIG. 1(a). In other words, the movement of the UIM card 11 in the backward direction is restricted by the sliding contact between the UIM card 11 and the projected parts 3g. The projected parts 3g are pushed by the spring terminal 13d of the connector 13a, when the connector 13a is contacted with the terminal face of the UIM card and is electrically connected thereto, so that the electric connection between the terminal face of the UIM card 11 and the connector 13 is preferably maintained. Since the projected parts 3g restricts the movement of the UIM card 11 in a direction opposite to the spring terminal 13d, the electric connection can be easily maintained.

In the card mounting apparatus 10 according to this embodiment, the UIM drawer 12 has a thick part compared to other parts of the card holding surface 12a and the thick part is located opposite to the connecter 13a, when the UIM drawer 12 is moved backward to a predetermined position. The thick part is pushed by the spring terminal 13d provided on the connector 13a, when the UIM card 11 is held on the card holding face 12a of the UIM drawer 12 which is moved backward to the predetermined position. Then the connector 13a is contacted and electrically connected with the terminal face of the UIM card 11, so that the electric connection between the terminal face of the UIM card 11 and the connector 13 is also preferably maintained in this aspect. The metal plate 13b can be slightly deflected toward the connector 13a by a fine adjustment of the thickness of the card holding face 12a of the UIM drawer 12 around the elongated guide holes 12e, so that the UIM card 11 can be also pushed toward the connector 31a by the metal plate 13b.

With the card mounting apparatus 10 according to this embodiment, the character input side housing 3 comprises a card holder 13 fixed in the card chamber 3f, and the card holder 13 comprises the inlet 13c oriented to the opening 3e open to the battery receiver 3c of the character input side housing 3 and holds the UIM card 11 inserted from the inlet 13c. The UIM drawer 12 is disposed between the inner wall with the projected parts 3g of the card chamber 3f and the card holder 13. The end faces of the end parts of the projected parts 3g passing through the elongated guide holes of the UIM drawer, and the back surface (inner surface) of the metal plate 13b forming the inlet 13c of the card holder 13 are smoothly connected, so that, upon insertion of the UIM card 11 along the card holding face 12a, the UIM card 11 can be inserted without any disturbance, as a result, preventing the UIM card 11 from contacting with the metal plate 13b and being stuck.

Further, the card mounting apparatus of this embodiment is easy to operate, since the UIM drawer 12 is disposed above the UIM card in FIG. 1. In order to move the UIM drawer backward, a user has only to move the UIM card 11 by shifting the pull tub arranged above the UIM card 11 in a backward direction. In other words, if the UIM drawer 12 is arranged below the UIM card 11 in FIG. 1, the pull tab 12b that is to be arranged below the UIM card 11, has to be moved in a backward direction to move the UIM card forward, which may cause an operational problem of the card mounting apparatus, since the UIM card is obstructive, while the pull tab 12b is arranged above the UIM card 11 in the card mounting apparatus according to this embodiment, so that the UIM card is not obstructive.

If the UIM drawer 12 is arranged above the UIM card 11 in FIG. 1 and the card holding face 12a is oriented downward, user may try to insert the UIM card 11 into the card chamber 3f along the face opposite to the card holding face 12a by mistake. The present invention is nevertheless highly beneficial, since, as described above, the projected parts 3g of the card chamber 3f preferably prevent a further insertion of the UIM card 11.

While the invention has been described with reference to exemplary embodiments and drawings, the invention is not limited to the embodiments described above and can be modified appropriately within a scope of claims. For example, the card mounting apparatus of the present invention can be applied to a portable electronic apparatus other than a cellular phone such as a palm top computer or a game machine with a function of wireless communication, or other various electronic apparatuses. A card used in the card mounting apparatus of this invention can be any card other than an IC card such as a UIM card 11, an SIM card and the like.

While the pull tab 12b of the UIM drawer 12 is exposed from the opening 3e open to the battery receiver 3c of the character input side housing 3 and projects from the opposite side of the card holding face 12a in the embodiment described above, the pull tab of the card holder can be provided with a concave part or a slit into which a finger or a nail can be put. Instead of the spring terminal 13d, other connecting terminals, such as a connecting terminal without resiliency can be used.

While the elongated guide holes 12e are formed as a guide in the UIM drawer 12 in the embodiment above, a guide groove can be formed, with which projected parts 3g shorter than those of the embodiment above can engage.

INDUSTRIAL APPLICABILITY

Thus, with the card mounting apparatus of this embodiment, upon insertion of a card, if the card is about to be inserted on the opposite side by mistake instead of the card receiving side, a wrong insertion of the card can be reliably prevented and damaging of the card or the card holder due to the wrong insertion can be inhibited beforehand.
