Has been. In addition, the mobile terminal device 1 includes a housing 41 that houses each component of the device, and a chassis 51 that holds each component inside.

  The memory card 10 is a SIM card in which unique identification information for specifying a telephone number is stored, and is inserted into the card slot 20 via the card tray 30.

  The card slot 20 includes therein a space for accommodating the card tray 30 and the memory card 10, a guide frame that supports the card tray 30 so that the card tray 30 can be pulled out, and an electrode connected to a terminal of the memory card 10. .

  FIG. 5 is a perspective view showing the card tray, and FIG. 6 is a perspective view seen from the back side of the card tray. FIG. 7 is a front view for explaining the relationship between the card tray and the upper surface of the chassis.

  The card tray 30 is a component that holds the memory card 10 in a state in which the memory card 10 can slide in the front-rear direction. As shown in FIGS. 5 and 6, the side wall 31, the back side wall 32, the upper cover 34, the pedestal 35, A knob 36 and a plurality of legs 37 and 38 are provided. Except for the upper cover 34 and the pedestal 35, the card tray 30 is integrally formed by resin injection molding.

  The left and right side walls 31, 31 surround the left and right sides of the accommodated memory card 10 and restrict the left and right movement of the memory card 10. The back side wall 32 hits one side of the back of the memory card 10 to be accommodated and regulates the slide end position of the memory card 10.

  The upper cover 34 covers the upper surface of the memory card 10 accommodated therein and restricts the upward movement of the memory card 10. The upper cover 34 is made of, for example, a thin metal plate, and three edge portions are fixed to the left and right side wall portions 31 and 31 and the back side wall portion 32, respectively. The upper cover 34 is formed with a notch 34z in the center on the front side, and an operator can press a finger or the like against the memory card 10 accommodated through the portion of the notch 34z.

  The pedestal 35 extends to the left and right partial areas on the lower side and the front side of the accommodated memory card 10 to support the memory card 10 from the lower side. The pedestal 35 is made of, for example, a thin metal plate, and is fixed to the left and right side walls 31, 31 respectively.

  As described above, the card tray 30 surrounds the left and right sides and the back side of the four sides of the memory card 10 to hold the memory card 10, while the front side of the memory card 10 is open. Has been. Therefore, the memory card 10 can be inserted into and removed from the card tray 30 by sliding in the direction along the card surface (the wide surface on the card) from the front side of the card tray 30.

  The knob 36 is formed so as to protrude upward (in the direction opposite to the chassis 51) to the right end (or the left end) on the front side of the card tray 30. An operator can pull out the card tray 30 from the card slot 20 by hooking his finger on the knob 36. The knob 36 is formed outside the right end of the memory card 10 to be accommodated, and does not hinder the sliding movement of the memory card 10 in the front-rear direction. As shown in FIG. 1, the knob 36 is provided at a position that can be seen from the opening of the battery accommodating portion 50 of the housing 41 in a state where the card tray 30 is accommodated in the card slot 20.

  The leg portion 37 is formed at the right end on the near side of the card tray 30 so as to protrude downward (in the direction in which the chassis 51 is present). As shown in FIG. 7, the leg portion 37 is formed to have a length that is in contact with or close to the upper surface (corresponding to the base surface) of the chassis 51.

  The leg portion 38 is formed to project downward at the left end on the near side of the card tray 30. As shown in FIG. 7, the leg part 38 is formed in the length which contacts or adjoins to the upper surface (equivalent to a base surface) of the chassis 51. As shown in FIG.

[Memory card removal operation]
In the card mounting portion configured as described above, the card tray 30 can be pulled out by placing a finger on the knob 36 in a state where the memory card 10 is accommodated, as shown in FIGS. By pulling out the card tray 30, the memory card 10 held on the card tray 30 is also pulled out, and the front side portion of the memory card 10 is exposed.

  Next, the operator presses the finger against the exposed portion of the memory card 10 and pulls it out to the near side by friction as shown in FIGS. At this time, pressure is applied downward between the memory card 10 and the card tray 30, but as shown in FIG. 7, the leg portions 37 and 38 of the card tray 30 come into contact with the upper surface of the chassis 51 and the memory card 10 and the card tray 30. The tray 30 is not bent and deformed so as to be bent. Therefore, the operator can pull out the memory card 10 smoothly.

  Subsequently, as shown in FIGS. 3 to 4, when the front side of the memory card 10 is pulled out about half, the operator can pinch the memory card 10 and take it out from the card tray 30.

[Configuration for preventing card tray spilling]
FIG. 8 is an enlarged front view showing the leg portion 37 of the card tray 30 in detail, and FIG. 9 is a front view showing the operation of the card tray 30B of the comparative example. The card tray 30B in FIG. 9 is an example of a configuration in which the shape of the leg portion 37B is not devised.

  The knob 36 and the leg portion 37 of the card tray 30 are integrally configured by resin injection molding. Therefore, if a general molding method is followed, as shown in the comparative example of FIG. 9, a relatively large inclination is provided on the left and right side surfaces 371B so that the leg portion 37B is tapered so as to facilitate die cutting. It is done. In addition, a roundness with a standard curvature radius is formed at the convex angle 373B between the side surface 371B of the leg portion 37B and the end surface 372B in contact with the chassis 51. Further, the end surface 372B is considered to be formed in parallel with the upper surface of the chassis 51.

  Here, consider a case where the knob 36 is pressed in the absence of the memory card 10 in the card tray 30B of the comparative example. In this case, coupled with the provision of the knob 36 toward the end, the end portion of the leg portion 37B slides inward, and the portion from the knob 36 to the leg portion 37B is easily rotationally deformed. (See FIGS. 9A and 9B).

  The leg portion 37 of the card tray 30 of the present embodiment is devised in some ways so that the above-described galling is less likely to occur.

  First, as one of the ideas, the end surface 372 of the leg portion 37 (see FIG. 8) is formed with an inclination in a direction in which the distance from the upper surface of the chassis 51 increases as it proceeds from the outside to the inside. Due to the inclination of the end surface 372, when the knob 36 is pressed, a reaction force opposite to the direction in which the leg portion 37 slides inward is applied from the upper surface of the chassis 51. Therefore, it is difficult for scouring as shown in FIG.

  Further, as one of the ideas, the outer side surface 371 of the leg portion 37 is formed with a minimum inclination that can be punched. This inclination is, for example, an inclination of 3 ° from a plane perpendicular to the upper surface of the chassis 51, and is substantially perpendicular to the upper surface of the chassis 51. Note that the side surface 371 may be formed completely vertically by molding using an undercut. Conversely, an inclination in the direction of projecting outward as the chassis 51 is approached may be provided. By forming the side surface 371 in this way, when the knob 36 is pressed, the leg portion 37 can support this force directly under the knob 36, and the galling as shown in FIG. Become.

  Furthermore, as one of the ideas, the convex angle 373 between the side surface 371 and the end surface 372 of the leg portion 37 is formed to be as sharp as possible (the smallest roundness that can be molded). With this configuration, when the knob 36 is pressed, the leg portion 37 is difficult to slide inward. Therefore, it is difficult for scouring as shown in FIG.

  Further, as one of the ideas, a concave groove 374 is formed in the center of the end portion of the leg portion 37. The concave groove 374 is a place where a mold-molded gate (inlet for molten resin) is disposed. The concave groove 374 prevents a resin convex portion generated at the gate portion from jumping out from the end surface 372. Therefore, even when the resin convex portion is generated at the gate portion, it is possible to avoid the inconvenience that the resin convex portion hits the upper surface of the chassis 51 and the leg portion 37 easily falls obliquely when the knob 36 is pressed.

(Modification 1)
FIG. 10 is a perspective view showing a modification of the card tray according to the embodiment of the present invention.

  As a configuration for preventing galling, the modification shown in FIG. 10 may be employed. On the card tray 30A of this modification, a horizontal bar portion 39 is installed between the left and right leg portions 37 and 38. The horizontal bar portion 39 is more preferably connected to the distal end side (the side closer to the upper surface of the chassis 51) of the leg portions 37 and 38, but may be connected to the middle portion of the leg portions 37 and 38.

  Such a horizontal bar portion 39 prevents the leg portion 37 from falling inward when the knob 36 is pressed.

(Modification 2)
FIG. 11 is a perspective view showing a modification of the memory card mounting portion according to the embodiment of the present invention, and FIG. 12 is a front view of the memory card mounting portion.

  As a configuration for preventing galling, the modification shown in FIGS. 11 and 12 may be employed. In this modification, grooves 52 and 52 for guiding the legs 37 and 38 when the card tray 30 is pulled out are provided on the upper surface of the chassis 51.

  The groove portions 52 and 52 are provided in a range in which the leg portions 37 and 38 move when the card tray 30 is pulled out from the card slot 20.

  The groove portions 52 and 52 prevent the leg portion 37 from falling inward when the knob 36 is pressed.

  As described above, according to the card tray 30 and the mobile terminal device 1 of this embodiment, the card tray 30 is provided with the leg portions 37 and 38 having a length in contact with or close to the upper surface of the chassis 51. Therefore, after the card tray 30 is pulled out, when the memory card 10 is pressed and slid and taken out, the card tray 30 and the memory card 10 are not bent so as to be bent. Therefore, the operator can insert and remove the memory card 10 smoothly.

  The embodiment of the present invention has been described above.

  In the above-described embodiment, the configuration in which two leg portions are provided on the left and right sides of the card tray has been described as an example. However, for example, a configuration in which one thick leg portion is provided at the center in the left-right direction of the card tray is adopted. You can also. Even with this configuration, it is possible to prevent bending when the memory card 10 is pressed and taken out.

  Further, in the above-described embodiment, the configuration in which the upper surface of the chassis 51 is applied as the base surface with which the leg portion is in contact with or close to the base portion is described as an example. May replace configuration.

  In the above-described embodiment, the configuration in which the memory card is a SIM card has been described as an example. However, the present invention is similarly applied to a case where a memory card for data storage or another IC card is used as a memory card. can do.

  The present invention can be applied to a mobile terminal device such as a mobile phone, a card tray of a memory card mounted in the device, and the like.
