Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to an electronic device in which a card-like medium can be inserted and removed, and particularly relates to an electronic device provided with a protection device that protects a card-like medium partially protruding from a card slot (insertion slot) of the electronic device. . The present invention is suitable for portable electronic devices such as notebook personal computers (hereinafter referred to as “notebook PCs”), personal digital assistants (PDAs), game machines, and digital cameras. .
[Technical background]

  Card-like media such as smart cards, PC cards, and memory cards are inserted into card slots provided in the casing of electronic devices, but some of them protrude from the casing without being completely stored in the casing. In some cases, data communication may be performed with an electronic device. Conventionally, several electronic devices having a mechanism for protecting a protruding portion of a card partially protruding from a card slot from an external force have been proposed.

For example, Patent Document 1 discloses a cover member that is attached to a housing so as to be rotatable between a position for closing a card slot and a position for opening the card slot, and extends parallel to the card when opened. Patent Document 2 discloses a protective cover that moves between a protective position that covers a memory card and an exposed position that exposes a part of the memory card. The memory card slot is recessed in a semi-cylindrical shape, and when the memory card is inserted into the memory card slot, the center of the rear end is exposed. The protective cover is urged to a protected position by a coil spring to prevent the rear end portion of the inserted memory card from being exposed. Patent Document 3 discloses a technique for fixing a protector composed of upper and lower frames, which is a separate member to the casing of the electronic device.
Japanese Patent Laid-Open No. 2002-298099 (Summary, FIGS. 3 to 6) JP 2000-113663 A (Abstract, paragraphs 0024, 0026, FIG. 3, FIG. 5) Registered Utility Model Publication No. 3059612 (summary, FIG. 3, FIG. 4)

  In Patent Document 1, opening and closing of the cover member must be performed separately from the insertion operation, and operability is poor. Patent Document 2 requires a mechanism for holding the protective cover in the exposed position together with the coil spring, and the concave portion of the memory card slot requires a height to insert two user fingers, so that the device is small. It is hard to do. In Patent Document 3, since the protector protrudes from the housing, the protector is brought into contact with an external member at the time of carrying, and the downsizing and the portability are reduced. Since the card-like medium is not always inserted into the electronic device, the card-like medium is automatically and inexpensively protected when the card-like medium is inserted, and the case shape is not impaired when the card-like medium is not inserted. There is a demand for protection devices that maintain the miniaturization of equipment.

  The present invention relates to an electronic device that realizes miniaturization and / or protects an inserted card-like medium automatically and with a simple configuration.

  An electronic apparatus according to one aspect of the present invention includes a housing having a card slot into which a card-like medium can be inserted and removed, and the card-like medium in a state where a part of the card-like medium protrudes from the card slot of the housing. A card holder electrically connected to the medium; and a protection device having a link mechanism, wherein the link mechanism is inserted into the casing from the card slot and a fulcrum portion rotatably connected to the casing. A force point portion that comes into contact with an end surface of the card-shaped medium, and the end surface of the card-shaped medium rotates around the fulcrum portion by pushing the force point portion and partially from the card slot. Projecting to protect the part of the card-like medium. In such an electronic device, when the card-like medium is inserted from the card slot, the link mechanism automatically protrudes to protect a part of the card-like medium. Therefore, the link mechanism of the protection device is displaced to the protection position by one action of insertion operation. Moreover, since the protective device uses a link mechanism without using a coil spring, it is possible to reduce the size in the insertion direction.

  For example, the link mechanism includes first, second, and third links connected in a U shape, and the first link includes the fulcrum portion and the force point portion, and the second link The first link is rotatably connected to the first link and can partially protrude from the card slot, and the third link is connected to the second link at one end so as to be rotatable. An end is rotatably attached to the housing, and when the end surface of the card-like medium presses the force point portion of the first link, the first link rotates around the fulcrum portion and the second link And the third link is rotated around the other end so that a part of the second link and the third link are the one of the card-like media. The part may be protected. As a result, a simple link mechanism can be configured.

  Until the end face of the card-like medium comes into contact with the force point portion of the first link, the second link is arranged in parallel with the insertion direction of the card-like medium, and the third link is the insertion The force point portion may be positioned closer to the card slot than the fulcrum portion. Since the end face of the third link forms a part of the card slot, it is possible to prevent the protective device from protruding from the housing.

  The card holder preferably has a flexible substrate. Thereby, it can be made thinner than the conventional rigid printed circuit board. The protection device can be accommodated in the difference in height between a card holder using a conventional rigid printed circuit board and a card holder using a flexible circuit board. As a result, the protective device can be disposed within the height range of the conventional card holder (that is, without hindering the downsizing of the electronic device).

  The card holder includes a connector that is mounted on the surface of the flexible substrate and configured to be electrically connected to the card-like medium, and a chip that converts an interface mounted on the back surface opposite to the surface of the flexible substrate. And the flexible substrate is bent between the connector and the chip, and the region where the connector is mounted is located in a direction from the front surface to the back surface rather than the region where the chip is mounted. It is preferable. By bending the flexible substrate, the back surface of the region of the flexible substrate on which the chip is mounted and the surface of the connector can be made substantially the same height. As a result, the card holder can be thinned in the height direction.

  An electronic apparatus according to another aspect of the present invention includes a housing having a card slot into which a card-like medium can be inserted and removed, and the card in a state where a part of the card-like medium protrudes from the card slot of the housing. A card holder electrically connected to the card-like medium, the card holder being mounted on the surface of the flexible board and configured to be electrically connected to the card-like medium. A chip for converting an interface mounted on the back surface opposite to the front surface of the flexible substrate, the flexible substrate being bent between the connector and the chip, and the region where the connector is mounted is It is located in the direction from the front surface to the back surface rather than the area where the chip is mounted. Such an electronic device can be made thinner in the direction side than the card slot of the housing.

  The card-like medium includes, for example, a smart card and a B-CAS card.

Although the present invention does not limit the type of the smart card 10, the contact type is used in this embodiment. Here, the contact type is a type that exchanges data and power by contacting a connector of a card holder (or a card reader / writer) of an electronic device via a metal terminal embedded on the surface of the card. The non-contact type is a type that exchanges data and power in a non-contact manner with a card holder via radio waves via an antenna embedded in the card. The integrated type is a type having both a contact type and a non-contact type interface.

  In the present embodiment, the smart card 10 is used as an example of a card-like medium. However, the present invention is not limited to this, and can be applied to, for example, a B-CAS (BS-Conditional Access Systems) card.

  FIG. 2 is a perspective view and a partially enlarged plan view showing the structure of the smart card 10. The smart card 10 has an IC chip 12 and metal terminals 14 on an IC module mounting portion 11a of a base 11 made of cured vinyl chloride.

FIG. 3A is a schematic partial cross-sectional view along the X direction in the vicinity of a card slot of a conventional notebook PC. As shown in FIG. 3 (a), a conventional base has an upper 116A dimension HA ₁ is 3mm positioned above the card slot 115A, the dimension HA ₂ positioned below the card slot 115A is 1mm And a lower portion 117A.

  FIG. 3B is a partially enlarged sectional view of FIG. As shown in FIG. 3B, the main part of the card holder 130A is provided in the upper part 116A, and the protective device is not provided in the conventional base. The card holder 130A is electrically connected to the smart card 10 with a part of the smart card 10 protruding from the base card slot 115A.

  The main part of the card holder 130A includes a printed circuit board 132A, a smart card connector 134, a smart card / PCMCIA interface conversion chip 136, and a PCMCIA connector 138.

  The printed board 132A is a rigid board and has both flat surfaces. The smart card connector 134 is configured to be mounted on the surface 132Aa of the printed circuit board 132A so as to be in electrical contact with the metal terminal 14 of the smart card 10. The chip 136 is connected to the smart card connector 134, converts the interface from the smart card interface to the PCMCIA interface, and is mounted on the back surface 132Ab opposite to the front surface 132Aa of the printed circuit board 132A. The PCMCIA connector 138 is connected to the chip 136 and connects the PCMCIA interface converted by the chip 136 to a CPU (control unit) mounted on a printed board (not shown) of the notebook PC 100.

  If the protective device is added as it is to the conventional base, the base becomes large in the Z direction, which causes a problem that the demand for thinning cannot be satisfied.

FIG. 4A is a schematic partial cross-sectional view along the X direction in the vicinity of the card slot 115 of the base 110. As shown in FIG. 4 (a), the base 110 of the present embodiment, the upper 116 dimension _{H 1} is 2mm positioned above the card slot 115, dimension H is positioned below the card slot 115 ₂ has a lower part 117 which is ₂ mm.

  FIG. 4B is a partially enlarged cross-sectional view of FIG. As shown in FIG. 4B, the main part of the card holder is provided in the upper part 116, and the protection device 140 is accommodated in the hatching area 117a of the lower part 117. The card holder 130 is electrically connected to the smart card 10 in a state where a part of the smart card 10 (a part 10b shown in FIG. 5C described later) protrudes from the card slot 115 of the base.

Thus, the base 110 of the present embodiment has a top 116 in which the conventional base of the upper 116A to 1mm thin, the hatched region 117a having a thickness _{H 3} of the 1mm lower 117 thicker 1mm lower 117A The protective device 140 is housed in the storage. Since the base 110 of this embodiment houses the protective device 140 without changing the height of the conventional base in the Z direction, the protective device 140 does not hinder downsizing of the notebook PC 100.

  The main part of the card holder 130 includes a flexible substrate 132, a smart card connector 134, a smart card / PCMCIA interface conversion chip 136, and a PCMCIA connector 138.

  The flexible board 132 is a foldable board and is thinner than the printed board 132A. Therefore, the base 110 can be made smaller in the height direction (Z direction) than the conventional base simply by using the flexible substrate 132. The smart card connector 134 is mounted on the surface 132a of the flexible substrate 132 and is configured to be electrically connected by contacting the metal terminal 14 of the smart card 10. The chip 136 is connected to the smart card connector 134, converts the interface from the smart card interface to the PCMCIA interface, and is mounted on the back surface 132b opposite to the front surface 132a of the flexible substrate 132. The PCMCIA connector 138 is connected to the chip 136 and connects the PCMCIA interface converted by the chip 136 to a CPU (control unit) mounted on a printed board (not shown) of the notebook PC 100.

  The flexible substrate 132 has a bent portion 132 c that is bent upward in the Z direction between the smart card connector 134 and the chip 136. As a result, the area 132d where the smart card connector 134 is mounted is located on the upper side in the Z direction (ie, at a higher position) from the front surface 132a toward the back surface 132b than the area 132e where the chip 136 is mounted. The bottom surface of the smart card connector 134 is substantially the same height as the surface of the region 132e.

  A bent portion 132c shown in FIG. 4B may be formed in advance on the flexible substrate 132, or the bent portion 132c is formed at the time of mounting by appropriately engaging the upper portion 116.

  In the conventional card holder 130A shown in FIG. 3B, the smart card connector 134 protrudes downward in the Z direction from the surface 132Aa of the printed board 132A. However, no circuit element is mounted on the surface 132Aa of the printed board 132A other than the smart card connector 134. For this reason, the card holder 130A does not effectively use the space between the surface 132Aa and the bottom surface of the connector 134, particularly the space corresponding to the surface 132Aa in the region where the chip 136 is mounted.

  On the other hand, the card holder 130 of this embodiment uses the flexible board 132 instead of the printed board 132A, and bends the flexible board 132 upward between the smart card connector 134 and the chip 136 in the Z direction. Yes. As a result, the card holder 130 can save a space between the surface 132a and the bottom surface of the smart card connector 134, particularly a useless space where no circuit element is mounted on the surface 132A side of the region 132e. 116 is made thin by about 1 mm. 3 (b) and 4 (b), the dotted line extending in the X direction indicates a surface that coincides with the upper surface of the inserted smart card 10.

  In this embodiment, the lower portion 117 of the base 110 is thickened by 1 mm, and the protective device 140 is housed in the region 117a. Thus, in this embodiment, the protection device 140 can be provided without increasing the thickness of the base 110 in the Z direction.

  The protection device 140 has a link mechanism composed of a plurality of links, and does not use an urging member, so that the configuration is simple. 5A to 5C are schematic plan views of the protection device 140. FIG. More specifically, FIG. 5A shows a state of the protection device 140 before the smart card 10 is inserted into the base 110. FIG. 5B shows a state of the protection device 140 while the smart card 10 is being inserted into the base 110. FIG. 5C shows a state of the protection device 140 after the smart card 10 is inserted into the base 110.

  The link mechanism includes a first link 141, a second link 144, and a third link 145 connected in a U shape. A simple link mechanism can be constituted by these three links, and the size and cost of the protection device 140 can be reduced.

The first link 141 is a rod-shaped member, and has a wide portion 141a on the upper side in the Y direction and a narrow portion 141b on the lower side in the Y direction. One end surface of the wide portion 141a 141a- ₁ is flat opposite 141a ₂ is in a hill shape. The narrow portion 141b is a constant width, the one end face 141b ₁ constitutes a flat surface with one end face 141a- _1.

  A fulcrum part 142 is formed at substantially the center of the wide part 141a. The fulcrum part 142 is rotatably connected to the base 110. FIG. 6A is a partially enlarged perspective view of the vicinity of the fulcrum part 142 or the wide part 141a. FIG. 6B is a cross-sectional view taken along the line EE in FIG. FIG. 6C is a rear view of the fulcrum part 142. As shown in FIGS. 6A to 6C, the fulcrum part 142 includes a support part 142a having the same height as the wide part 141a, a bent part 142b, and a part 117b of the lower part 117 of the base 110. Engaging portion 142c. The support portion 142 is not limited to the structure of this embodiment, such as connecting the first link 141 and the lower portion 117 of the base 110 with pins. The first link 141 is rotatably attached to the lower part 117 of the base 110 around the fulcrum part 142. In this embodiment, as shown in FIG. 5A, the angle θ with respect to the Y axis of the first link 141 is 30 degrees before the smart card 10 is inserted into the base 110.

Further, the first link 141 has a power point portion 143 at one end 141c. The force point portion 143 is inserted into the base 110 from the card slot 115 and comes into contact with the end face 10a of the smart card 10 indicated by a dotted line in FIGS. 5B and 5C. FIG. 7 is a plan view of the power point portion 143. As shown in the figure, the force point portion 143 has a base portion 143a of M ₁ × M ₂ and a chamfered portion 143b of a radius M ₃ . In this embodiment, M ₁ = M ₂ = M ₃ = 2 mm. The thickness of the force point portion 143 is not limited, but is 1 mm or less in this embodiment. The force point portion 143 can contact the end surface 10a of the smart card 10 and the chamfered portion 143b.

  The second link 144 is a rod-like member that is rotatably connected to the other end 141 d of the first link 141, and can partially protrude from the card slot 115. 5A to 5C, the end face of the card slot 115 is indicated by 115a. Note that the end surface 115a is flush with the outer surface of the side surface 114 of FIG.

  The third link 145 has one end 145a rotatably connected to the second link 144 by a pin 146a and the other end 145b rotatably attached to the lower portion 117 of the base 110 by the pin 146b. FIGS. 8A to 8C are an upper perspective view, a side view, and a lower perspective view, respectively, of part A in FIG. 5A. FIGS. 9A to 9C are an upper perspective view, a side view, and a lower perspective view, respectively, of the portion B in FIG. 5A.

  Hereinafter, the operation of the protection device 140 will be described.

As shown in FIG. 5 (a), the end face 10a of the smart card 10 until contacts the point portion 143 of the first link 141, disposed parallel to the second link 144 in the insertion direction _{X 1} of the smart card 10 Is done. FIG. 5A shows an initial position of the link mechanism. The third link 145 is disposed in the Y direction perpendicular to the insertion direction X _1.

  In FIG. 5A, the end surface 145 c of the third link 145 coincides with the end surface 115 a of the card slot 115. If the end surface 145c of the third link 145 protrudes outward (right side in FIG. 5A) from the end surface 115a of the card slot 115, the protruding portion collides with an external member and becomes weak. Further, if the end face 145c of the third link 145 protrudes inward (left side in FIG. 5A) from the end face 115a of the card slot 115, it protrudes more to protect the protruding part 10b of the smart card 10. Must be less efficient.

  The force point portion 143 is located closer to the card slot than the fulcrum portion 142. As a result, the end face 10 a of the smart card 10 can be moved by first contacting the power point portion 143 within the protection device 140.

  The link mechanism of the protection device 140 is such that the end surface 10a of the smart card 10 pushes the force point portion 143, and the fulcrum portion 142 from FIG. 5 (a) to FIG. 5 (b) and FIG. 5 (b) to FIG. Rotate clockwise around Referring to FIG. 5B, it is understood that the length of the first link 141 in the Y-axis direction is substantially equal to the length of the card slot 115 in the Y-axis direction.

  FIG. 5C shows a state in which the smart card 10 is inserted into the base 110 and the metal terminal 14 of the smart card 10 is connected to the smart card connector 134 of the card holder 130. FIG. 5C shows a protection position of the link mechanism, and the first link 141 is inclined by an angle −θ with respect to the Y axis. As described above, the card holder 130 is electrically connected to the smart card 10 in a state where a part 10 b of the smart card 10 protrudes from the card slot 115 of the base 110. The protection device 140 partially protrudes from the end surface 115 a of the card slot 115 and protects a part 10 b of the smart card 10. Projecting from the end surface 115 a of the card slot 115 of the protection device 140 are a part of the second link 144 and a part of the third link 145.

  As described above, when the end face 10a of the smart card 10 pushes the force point portion 143 of the first link 141, the first link 141 rotates clockwise around the fulcrum portion 142, and the second link 144 is moved to the card slot 115. To partially protrude from. Further, the third link 145 is rotated clockwise around the other end 145 b to partially protrude from the card slot 115. The distance D in the X direction in which the second link 144 and the third link 145 protrude from the end face 115a of the card slot 115 is the distance D in the X direction in the present embodiment, where a part 10b of the smart card 10 protrudes from the end face 115a of the card slot 115. 120 mm equal to the length.

When the smart card 10 is inserted from the card slot 115, the link mechanism automatically protrudes from the card slot 115 to protect the part 10b of the smart card 10. Therefore, the link mechanism of the protection device 140 is displaced to the protection position by one action of insertion operation. The protective device 140 can be miniaturized in the insertion direction X ₁ because it utilizes a link mechanism without using a coil spring.

  In FIG. 5C, the metal terminal 14 of the smart card 10 and the smart card connector 134 of the card holder 130 come into contact with each other. As a result, the control unit of the notebook PC (not shown) and the CPU 12c of the smart card 10 can communicate with each other. Thereafter, the user operates the keyboard 120 and the pointing device 122 and performs necessary processing while referring to the LCD screen 170 of the LCD bezel frame 160. Power and data are transmitted and received through the metal terminal 14, the smart card connector 134, the chip 136, and the PCMCIA connector.

After completing the necessary processing, the user removes the smart card 10 from the base 110. When the smart card 10 is removed, the link mechanism is in the state shown in FIG.
