Description

  The present invention relates to a card type recording apparatus and a slot apparatus, and more particularly to a card type recording apparatus such as a memory card.

  In general, a digital camera or the like, which is one of electronic devices, uses a card-type recording device (hereinafter referred to as a card medium) such as a memory card in order to record electronic data such as a captured image. The card medium includes a flash memory IC and a card controller IC that controls writing and reading to and from the flash memory IC.

  In recent years, the need for writing electronic data on a card medium at a high speed has increased with the increase in the definition of images and the increase in frame rate. As a result, the power consumption of the card medium increases, and it is necessary to cope with the heat generation of the card medium accompanying the increase in the power consumption.

  In order to keep the recording operation in the card medium normal, it is necessary to suppress the heat generation to a temperature at which the flash memory IC and the card controller IC do not run out of heat. Furthermore, since the card medium is inserted and removed by the user's manual operation, it is necessary to prevent the card medium from becoming so hot that the user feels uncomfortable when removing the card medium from the electronic device. For this reason, various structures for dissipating heat from the card medium have been proposed.

  For example, when the first heat transfer member is disposed in the cover unit that opens and closes the insertion slot for accommodating the card medium and the insertion slot is closed, the first heat transfer member is on the card medium insertion slot side. There is an electronic device that comes into contact with an end (Patent Document 1).

JP 2012-023131 A

  As described above, in Patent Document 1, the heat of the card medium is radiated through the first heat transfer member provided in the cover unit. However, in order to support the cover unit so that it can be opened and closed, a clearance is required between the cover unit and the surrounding members. For this reason, there are few heat transfer paths which diffuse the heat conducted to the cover unit, and it is difficult to efficiently diffuse and release the heat generated from the card medium. And the temperature of a cover unit also rises.

  In Patent Document 1, a second heat transfer member is provided in order to diffuse and release heat from the first heat transfer member. However, when the first and second heat transfer members are used, a heat dissipation path is provided. However, the heat dissipation efficiency decreases.

  Accordingly, an object of the present invention is to provide a card type recording apparatus and a slot apparatus with good heat dissipation efficiency.

  In order to achieve the above object, the card type recording apparatus according to the present invention provides the card that contacts the slot device in the insertion direction when the card type recording apparatus is inserted into the slot device into which the card type recording apparatus is inserted. An outer cover having thermal conductivity connecting at least a part of one end of the card type recording apparatus parallel to the insertion direction and at least a part of the end part of the card type recording apparatus. It is characterized by having.

  Further, the slot device according to the present invention is a slot device into which the card type recording device is inserted and removed, and has thermal conductivity that comes into contact with the end portion of the outer cover when the card type recording device is inserted. It has the contact part provided with.

  According to the present invention, heat can be conducted to the contact portion of the slot device at the end of the card-type recording apparatus on the electric contact side to dissipate heat, so that an efficient heat dissipation path can be configured.

  Hereinafter, a card type recording apparatus according to an embodiment of the present invention and a slot device into which the card type recording apparatus is inserted and removed will be described with reference to the drawings.

  FIG. 1 is a perspective view showing an appearance of an example of a card type recording apparatus according to an embodiment of the present invention. FIG. 1A is a perspective view of the card-type recording device as viewed from the first surface side, and FIG. 1B is a perspective view of the card-type recording device as viewed from the second surface side facing the first surface. is there.

  As shown in the figure, a card type recording apparatus (hereinafter referred to as a card medium) 1 has a thin and flat shape. Since the card medium 1 is used by being inserted into a slot device (hereinafter simply referred to as a slot) provided in an electronic apparatus such as a digital camera, the card medium 1 is formed into a thin so-called card shape.

  For convenience of explanation, a coordinate system is set for the card medium 1 as shown in FIG. Here, the direction in which the card medium 1 is inserted into the slot is the insertion direction, and the direction opposite to the insertion direction is the removal direction.

  In the card medium 1, a card connector 503 is disposed on an end surface (end portion) in the insertion direction. The end surface (that is, the arrangement portion) on which the card connector 503 is arranged is called a terminal surface 103. On the other hand, a surface facing the terminal surface 103 is a rear end surface 104. In the card medium 1, the direction parallel to the short side surface is the thickness direction and the direction parallel to the long side surface is the width direction among the directions orthogonal to (intersect) the insertion and removal directions. The surfaces of the card medium 1 in the thickness direction are defined as a first surface 101 and a second surface 102, respectively. As for both side surfaces in the width direction, the left side 105 is the left side 105 and the right side 106 is the right side in the insertion direction with the first surface 101 facing up.

  FIG. 2 is a perspective view showing an example of a digital camera (video camera) which is one of the electronic devices including the slot device into which the card medium shown in FIG. 1 is inserted. FIG. 2A is a perspective view of the digital camera as viewed from the front side, and FIG. 2B is a perspective view of the digital camera as viewed from the rear side. FIG. 3 is a block diagram showing an example of the configuration of the digital camera shown in FIG.

  As shown in FIGS. 2 and 3, the digital camera (hereinafter simply referred to as a camera) 2 has a lens unit (hereinafter simply referred to as a lens) 201. The camera 2 captures a subject image (optical image) incident through the lens 201 and records electronic data (image data) corresponding to the captured subject image on the card medium 1.

  This will be specifically described. A subject image is formed on the image sensor 301 via the lens 201. Then, the control unit 303 drives and controls the image sensor 301 in accordance with the operation of the release switch 206 to convert the subject image into a video signal and send it to the image processing unit 302. The image processing unit 302 generates image data of a predetermined format from the video signal under the control of the control unit 303, and sends the image data to the recording control unit 304.

  The recording control unit 304 records image data on the card medium 1 inserted into the slot 305 under the control of the control unit 303. Further, a video signal is sent from the image processing unit 302 to the monitor image generating unit 306. The monitor image generation unit 306 converts the video signal into an image signal that can be displayed on the LCD monitor 202. The monitor image generation unit 306 superimposes the character information generated by the character generator 307 on the image signal and displays it on the LCD monitor 202 as an image. The image corresponding to the video signal is a still image or a moving image.

  In the illustrated camera 2, the image data recorded on the card medium 1 can be displayed on the LCD monitor 202 as a reproduced image. Under the control of the control unit 303, the recording control unit 304 reads image data designated by the user from the card medium 1. The monitor image generation unit 306 converts the image data into an image signal that can be displayed on the LCD monitor 202 and displays the image signal on the LCD monitor 202 as a video.

  The camera 2 includes an operation unit for receiving an operation by a user. For example, there is a power switch 203 as one of the operation units. When the power switch 203 is pressed down, the power of the camera 2 can be turned on or off. Further, in the illustrated camera 2, the touch panel 204 is disposed so as to overlap the LCD monitor 202. The touch panel 204 is combined with a character display on the LCD monitor 202 to provide a GUI (graphic user interface). For example, by a touch operation on the touch panel 204, the user can change the setting of the camera 2 or select a playback image.

  By operating the mode switching dial 205, the operation mode of the camera 2 can be switched between a shooting mode for shooting and a playback mode for playing back image data recorded on the card medium 1.

  Note that an operation signal corresponding to the operation of the power switch 203, the touch panel 204, the mode switching dial 205, or the release switch 206 is input to the control unit 303. And the control part 303 controls the camera 2 based on the operation signal and the communication result of each part of the camera 2. Although not illustrated, the camera 2 includes a battery, and power is supplied from the battery to the camera 2.

  FIG. 4 is a block diagram showing an example of the configuration of the card medium shown in FIG. FIG. 5 is an exploded perspective view showing the card medium shown in FIG.

  FIG. 6 is a diagram for explaining the inside of the card medium shown in FIG. FIG. 6A is a plan view seen from the first surface side of the card medium, and FIG. 6B is a plan view showing a state where the first surface card exterior is removed. FIG. 6C is a plan view seen from the second surface side of the card medium, and FIG. 6D is a plan view showing a state where the second surface card exterior is removed.

  As shown in FIGS. 1 and 4 to 6, the card medium 1 includes a card substrate 502 on which a power supply IC 401, a controller IC 402, and a flash memory IC 403 are mounted. 5 and 6, the power supply IC 401 is not shown. At least each of the power supply IC 401, the controller IC 402, and the flash memory IC 403 is an electrical element.

  The power supply IC 401 controls the drive power supplied from the camera 2 and distributes it to the controller IC 402 and the flash memory IC 403 with appropriate voltages. The controller IC 402 accesses the flash memory IC 403 that is a nonvolatile memory, and controls recording and reading of electronic data (image data).

  A plurality of flash memory ICs 403 may be mounted on the card substrate 502. As shown in FIGS. 6B and 6D, in the illustrated card medium 1, two flash memory ICs 403 are mounted in total, two on the front surface and the back surface of the card substrate 502. The number of flash memory ICs 403 varies according to the recording capacity of the card medium 1.

  The controller IC 402 and the flash memory IC 403 consume most of the power consumed by the card medium 1 during the recording or reproducing operation. As a result, each of the controller IC 402 and the flash memory IC 403 generates heat. Therefore, it is necessary to radiate the heat generated in the controller IC 402 and the flash memory IC 403 so that the operation of the card medium 1 is not hindered by the generation of the heat.

  A card connector 503 is attached to the card substrate 502 by soldering. As shown in FIG. 5, the card connector 503 is obtained by insert-molding a metal card electrical contact 505 on a card connector base 504 formed of an insulating resin. A lead portion 505a of the card electrical contact 505 is soldered to the card substrate 502. Here, a plurality of contacts are collectively referred to as a card electrical contact 505.

  The card electrical contact 505 includes a power card electrical contact that is connected to the power supply IC 401 and functions as a power supply line. The card electrical contact 505 includes a communication card electrical contact that is connected to the controller IC 402 and functions as a communication signal line. Here, since the role of each of the card electrical contacts 505 is not important, the power card electrical contact and the communication card electrical contact will be described without any particular distinction.

  As shown in FIGS. 5 and 6, the card substrate 502 is surrounded by a substantially U-shaped card frame 506. The card frame 506 is formed of an insulating resin, engages with the card connector base 504, and surrounds the side surface of the card substrate 502 orthogonal to the thickness direction. The card frame 506 and the card connector base 504 form a card left side guide part 107 and a card right side guide part 108 for fitting into a slot 305 described later (see FIG. 1).

  The card left side guide part 107 and the card right side guide part 108 are asymmetrical to each other. That is, the directionality is determined by the card left side guide portion 107 and the card right side guide portion 108 when mating with the slot 305.

  The card connector base 504 and the card frame body 506 constitute a resin frame. Then, an exterior cover (hereinafter simply referred to as an exterior) that forms both surfaces in the thickness direction of the card medium 1 is attached to the resin frame. Here, the surface on which a large number of controller ICs 402 and flash memory ICs 403 as heat sources are arranged is referred to as a first surface 101, and the exterior thereof is referred to as a first surface card exterior 501. Also, the surface on which the controller IC 402 is not disposed is the second surface 102, and the exterior thereof is the second surface card exterior 507. In other words, in the present embodiment, in the card medium 1, the surface on the side where many heat sources are arranged in the thickness direction is the first surface 101, and the other surface is the second surface 102. The second face card exterior 507 is formed of a thin and highly rigid metal, for example, a stainless steel material in order to make the card medium 1 thin. The first surface card exterior 501 and the second surface card exterior 507 are fixed to the resin frame by a hook structure using an engaging claw or adhesion.

  As will be described later, the first surface card exterior 501 communicates at least a part of one surface in the thickness direction of the card medium 1 and at least a part of the end surface on which the card connector 503 is disposed.

  FIG. 7 is a perspective view for explaining a first face card exterior of the card medium shown in FIG. FIG. 7A is a perspective view seen from the front side, and FIG. 7B is a perspective view seen from the back side.

  The first face card exterior 501 is formed of a material having rigidity and high thermal conductivity (thermal conductivity), for example, an aluminum alloy or a magnesium alloy. A wide surface that defines the first surface 101 of the card medium 1 that is the main surface of the first surface card exterior 501 is referred to as a main surface 701. That is, of the first card exterior 501, the surface having the largest area on the same surface is referred to as a main surface 701. Mounting claws 702a to 702d that engage with the resin frame are formed at substantially corners of the main surface 701, respectively. Furthermore, two surfaces are provided that are bent and connected approximately 90 degrees in the direction from the main surface 701 to the terminal surface 103. As will be described later, these two surfaces are surfaces that conduct heat generated from the controller IC 402 and the flash memory IC 403. In the following description, the first heat transfer surface (first heat transfer unit) 703 and the second heat transfer surface are used. It is referred to as a surface (second heat conduction part) 704.

  As shown in FIG. 1, the heat transfer surface 703 is formed on the left side 105 side of the card connector 503 from the main surface 701. Similarly, the heat transfer surface 704 is connected to the main surface 701 on the right side surface 106 side. As a result, the first heat transfer surface 703 and the second heat transfer surface 704 are positioned substantially on the same plane as the end surface of the card connector base 504 (that is, one surface side of the card medium), thereby forming the terminal surface 103.

  Further, as shown in FIG. 7B, a rib 705 is formed on the inner side of the first surface card exterior 501 in a range not interfering with the controller IC 402 and the flash memory IC 403 located immediately below the main surface 701. As a result, the rigidity of the first face card exterior 501 is increased. In addition, thick portions 707 and 708 that connect the rib 705 to the heat transfer surface 703 and the heat transfer surface 704 are provided inside the first surface card exterior 501.

  It should be noted that when each of the first surface card exterior 501 and the second surface card exterior 507 is formed of a conductive material such as an aluminum alloy or stainless steel, it should not be short-circuited with the card substrate 502 and the card electrical contact 505. Is required.

  In the card medium 1, the first surface card exterior 501 and the second surface card exterior 507 are fixed by sandwiching the above-described resin frame. For this reason, the space in which the card substrate 502 is accommodated is secured by the thickness of the resin frame. Further, thick portions 707 and 708 are inserted into notches 508 and 509 (see FIG. 5) formed in the card connector base 504, respectively. As a result, the position in the width direction of the first face card exterior 501 with respect to the card electrical contact 505 is restricted and does not contact each other.

  Further, the electrical contact portion rib 510 provided on the card connector base 504 ensures a separation distance in the thickness direction between the card electrical contact 505 and the first surface card exterior 501. This prevents a short circuit and secures a connect space 109 into which the connector portion of the slot 305 is inserted.

  FIG. 8 is a diagram for explaining the structure of the card medium shown in FIG. 8A is a plan view seen from the first surface side of the card medium, and FIG. 8B is a cross-sectional view taken along line A1-A1 shown in FIG. 8A. FIG. 8C is a cross-sectional view taken along line B1-B1 shown in FIG. For convenience of explanation, in FIG. 8B and FIG. 8C, the first face card exterior 501 is hatched.

  Referring to FIG. 8B, the first surface card exterior 501 is fixed in contact with the stepped portion between the electrical contact portion rib 510 and the card frame 506. On the other hand, the second surface card exterior 507 is fixed in contact with the card connector base 504 and the card frame 506. Thereby, a storage space for the card substrate 502 is secured. Clearances 801 and 802 are formed between the inner surface of the second surface card exterior 501 and the upper surfaces of the controller IC 402 and the flash memory IC 403 in consideration of the dimensional tolerance of each component and the mounting floating of each IC. And heat conductive grease or heat conductive rubber is inserted so that the space | gap by clearance 801 and 802 may be filled up. The heat generated in the controller IC 402 and the flash memory IC 403 is conducted to the main surface 701 of the first surface card exterior 501 by heat conductive grease or heat conductive rubber.

  Referring to FIG. 8C, the heat transfer surface 703 is continuously formed from the main surface 701 to the terminal surface 103. And the cross section of the 1st surface card | curd exterior 501 increases gradually in thickness by the rib 705 and the thick part 707 toward the heat-transfer surface 703. FIG. Although not shown, the thickness of the heat transfer surface 704 side changes in the same manner. Thus, as described above, the rigidity of the first surface card exterior 501 can be increased, and heat can be smoothly transferred from the main surface 701 toward the heat transfer surfaces 703 and 704.

  FIG. 9 is a perspective view of a state in which a card medium is inserted into the camera shown in FIG.

  The camera 2 is provided with a slot, and a slot port 901 into which the card medium 1 is inserted appears when the slot lid 207 is opened. The slot cover 207 is pivotally supported by the camera 2 and is urged in the opening direction by a spring (not shown). In the closed state, the slot lid 207 is locked while the hook 902 is engaged. When the operation knob 208 (see FIG. 2) is operated, the hook 902 is disengaged and the slot lid 207 is opened. . A slot, which will be described later, is disposed in the back of the slot port 901.

  FIG. 10 is a conceptual diagram for explaining slots provided in the camera shown in FIG. FIG. 10 (a) is a perspective view showing the slot from the card medium insertion side, and FIG. 10 (b) is a perspective view showing the slot from the opposite side to FIG. 10 (a).

  The slot 305 has a slot base 1001, a slot cover 1002, and a slot substrate 1003. The slot base 1001 and the slot cover 1002 are mounted on the slot substrate 1003 by soldering while being engaged with each other.

  10 shows a state in which the slot cover 1002 is removed for convenience of explanation, the slot base 1001 and the slot cover 1002 are integrally combined to form the slot 305.

  The slot base 1001 is made of resin, and a metal slot electrical contact 1004 is insert-molded. The slot electrical contact 1004 is a group of a plurality of electrical contacts. The slot base 1001 is formed with guide fitting portions corresponding to the card left side guide portion 107 and the card right side guide portion 108 of the card medium 1.

  The slot base base 1001 is formed with a slot left side guide part 1005 and a slot right side guide part 1006. The slot left side guide portion 1005 has a shape that fits into the card left side guide portion 107. Similarly, the slot right side guide portion 1006 has a shape that fits into the card right side guide portion 108.

  As described above, since the card left side guide portion 107 and the card right side guide portion 108 are asymmetrical to each other, the card medium 1 can be inserted only in the direction in which the upper and lower sides and the left and right sides match the slot base 1001. . In this way, the card medium 1 is mechanically connected to the slot 305 by fitting the guide portions.

  A slot connector portion 1007 extends from the slot base 1001. The slot electrical contact 1004 has elasticity, and the slot electrical contact 1004 protrudes displaceably from one surface of the slot connector portion 1007. When the card medium is inserted, the slot connector unit 1007 enters the connect space 109. Then, the slot electrical contact 1004 elastically contacts the card electrical contact 505, and electrical connection is made.

  Between the slot connector portion 1007 and the slot left side guide portion 1005 or the slot right side guide portion 1006, a surface that contacts the heat transfer surfaces 703 and 704 is formed when the card medium 1 is inserted. Since heat is conducted to these surfaces from the heat transfer surfaces 703 and 704 of the card medium 1, they are referred to as heat receiving portions 1008 and 1009 here.

  For example, the heat receiving portions 1008 and 1009 are formed of heat conductive rubber having elasticity, and are bonded to the metal slot heat transfer plate 1010 on the surface opposite to the surface in contact with the card medium 1. The slot heat transfer plate 1010 is formed of a metal having a high thermal conductivity, for example, a copper alloy. The slot heat transfer plate 1010 is fixed to the structural frame of the camera 2 together with the slot base 1001 and the slot substrate 1003 by screws 1011 and 1012. Further, the arm portions 1013 and 1014 extending from the slot heat transfer plate 1010 are soldered to the land of the slot substrate 1003 and connected to a pattern having a high residual copper ratio such as a ground layer of the slot substrate 1003.

  The slot cover 1002 is formed of a thin plate made of stainless steel, and guides the card medium 1 toward the slot base 1001 when the card medium 1 is inserted. Further, the slot cover 1002 is provided with an eject mechanism for removing (removing) the card medium.

  FIG. 11 is a view for explaining the operation of the eject mechanism attached to the slot cover shown in FIG. FIG. 11A is a perspective view in which the slot cover is omitted with the card medium ejected, and FIG. 11B is a plan view of the card medium ejected. FIG. 11C is a plan view showing the slot cover omitted with the card-type medium ejected. Further, FIG. 11D is a perspective view in which the slot cover is omitted with the card medium inserted, and FIG. 11E is a plan view of the state in which the card medium is inserted. FIG. 11F is a plan view in which the slot cover is omitted with the card-type medium inserted.

  A rotary arm 1017 is attached to the slot cover 1002 so as to be rotatable about a shaft 1018. One end of the rotary arm 1017 is slidably connected to the eject arm 1016, and the other end is swingably connected to the eject plate 1101. The eject plate 1101 is provided with a claw portion that comes into contact with the terminal surface 103 of the card medium 1.

  The eject arm 1016 and the eject plate 1101 are restricted by a guide shape (not shown) formed by the slot cover 1002 so as to be movable only in parallel with the insertion and removal directions of the card medium 1. An eject button 1015 is attached to the tip of the eject arm 1016. The eject button 1015 is exposed to the side of the slot opening 901 when the slot lid 207 is opened (see FIG. 9). Thereby, the user can eject the card medium 1 by operating the eject button 1015.

  When the card medium 1 is inserted into the slot 305, the above-described guide portion is started to be fitted from a predetermined position. Then, as shown in FIG. 11C, the terminal surface 103 of the card medium 1 comes into contact with an eject plate 1101 (indicated by double line hatching). Further, when the card medium 1 is advanced in the insertion direction, the eject plate 1101 that is in contact with the terminal surface 103 is pressed and moved in the insertion direction so that the card medium 1 hits a predetermined surface as shown in FIG. Move up.

  Along with the movement of the eject plate 1101, the rotary arm 1017 that is swingably connected rotates clockwise around the shaft 1018 from the state shown in FIG. 11B to the state shown in FIG. . As the rotary arm 1017 rotates, the eject arm 1016 that is swingably connected moves in parallel with the card medium 1 removal direction. Finally, as shown in FIG. 11 (e), the eject button 1015 is moved to a position protruding a predetermined amount from the rear end face 104 of the card medium 1, and can be operated when the slot lid 207 is opened.

  By the above-described insertion operation, the eject button 1015 is projected. When the eject button 1015 is pressed in the insertion direction of the card medium 1, the eject arm 1016 moves and the rotary arm 1017 rotates about the axis 1018. The rotating arm 1017 rotates counterclockwise from the state shown in FIG. 11E to the state shown in FIG. As the rotary arm 1017 rotates, the eject plate 1101 moves from the state shown in FIG. 11F to the state shown in FIG.

  As a result, the card medium 1 in contact with the eject plate 1101 moves in the removal direction. Since the card medium 1 protrudes from the slot port 901 by a predetermined amount, the user can take the card medium 1 by taking it.

  FIG. 12 is an enlarged view showing the vicinity of the heat receiving portion shown in FIG. FIG. 12A is a view showing one heat receiving portion (first heat receiving portion) 1008 side, and FIG. 12B is a view showing the other heat receiving portion (second heat receiving portion) 1009 side.

  As described above, the eject plate 1101 is formed with the claws 1201 and 1202. The claws 1201 and 1202 are located outside the heat receiving portions 1008 and 1009 in the width direction, and come into contact with the card medium 1 with a wide span. Accordingly, the insertion and removal can be stably performed while reducing the inclination of the eject plate 1101 and the card medium 1 during the insertion / removal operation.

  Here, a heat transfer path when the card medium 1 is inserted into the slot 305 will be described.

  FIG. 13 is a diagram for explaining an insertion process and an insertion state of the card medium shown in FIG. FIG. 13A is a plan view showing insertion of a card medium, and FIGS. 13B and 13C are cross-sectional views taken along line B2-B2 shown in FIG. 13A. Moreover, FIG.13 (d) is sectional drawing along the A2-A2 line shown to Fig.13 (a).

  FIG. 13B shows a process of inserting the card medium 1. Here, the heat transfer surface 703 and the heat receiving portion 1008 (shown in cross section by cross-hatching) are not yet in contact with each other. As described above, the heat receiving portion 1008 is formed of a heat conductive rubber having elasticity, and is formed so as to protrude by a predetermined amount from the abutting surface 1301 of the slot base 1001 facing the terminal surface 103.

  FIG. 13C shows a state in which the card medium 1 is inserted to a position where it substantially contacts the abutting surface 1301 of the slot base 1001. In this state, the terminal surface 103 including the heat transfer surface 703 is inserted to a position where it comes into contact with the abutting surface 1301. At this time, the heat receiving portion 1008 is pushed by the heat transfer surface 703 and compressed between the slot heat transfer plate 1010. Then, heat is conducted between the heat transfer surface 703 and the slot heat transfer plate 1010 via the compressed heat receiving portion 1008.

  By compressing the heat receiving portion 1008, there is no gap between the heat transfer surface 703 and the thermal resistance is lowered. Although not shown, heat is conducted to the slot heat transfer plate 1010 via the heat receiving portion 1009 on the heat transfer surface 704 side as well. Since heat receiving portions 1008 and 1009 have elasticity, a heat receiving portion reaction force indicated by arrow 1302 is generated when compressed. Since the position restriction in the insertion / extraction direction of the card medium 1 is performed by the heat receiving portion reaction force, the play in the insertion / extraction direction of the card medium 1 in the state inserted in the slot 305 can be reduced. Specifically, in the present embodiment, the heat receiving portion reaction force 1302 acts in the removal direction of the card medium 1, so that the card medium 5 is restricted in its insertion direction by each heat receiving portion, and the position in the removal direction is the slot lid 207. It is regulated by (Regulatory Department).

  14 is a cross-sectional view showing the relationship between the card medium and the slot lid in the inserted state of the card medium shown in FIG.

  As shown in the drawing, a convex portion 1401 is provided on the inner surface side of the slot lid 207, and the convex portion 1401 comes into contact with the rear end surface 104 when the card medium 1 is inserted. This prevents the card medium 1 from moving in the removal direction. Since the slot lid 207 is locked in the closed state by the hook 902, the card medium 1 cannot move in the removal direction as long as the slot lid 207 is closed. That is, the card medium 1 can maintain the insertion position where the terminal surface 103 including the heat transfer surface 703 comes into contact with the contact surface 1301.

  As described above, the heat generated by driving the controller IC 402 and the flash memory IC 403 is conducted to the main surface 701 of the first surface card exterior 501 through heat conduction grease or the like. Thereafter, heat is conducted from the heat transfer surfaces 703 and 704 to the slot heat transfer plate 1010 via the heat receiving portions 1008 and 1009. The heat conducted to the slot heat transfer plate 1010 is diffused and dissipated through the ground layer pattern of the slot substrate 1003 having a high residual copper ratio (that is, high thermal diffusibility). Instead of the slot heat transfer plate 1010, a radiator, for example, a heat sink having a large number of cooling fins may be used.

  Further, as described above, the card electrical contact 505 is disposed at the center of the terminal surface 103, and the heat transfer surfaces 703 and 704 are disposed outside the card electrical contact 505. As a result, the points of action of the heat receiving portion reaction force received by the card medium 1 from the heat receiving portions 1008 and 1009 are dispersed near both ends of the terminal surface 103. Therefore, a rotation moment due to the heat receiving portion reaction force is hardly generated in the card medium 1, and the contact state of the card electrical contact 505 can be kept stable. Furthermore, it is possible to smoothly perform the insertion / extraction operation by reducing the inclination of the card medium 1.

  Here, referring to FIG. 13 (d), here, the contact state between the card electrical contact 505 and the slot electrical contact 1004 in the inserted state of the card medium 1 is shown. As described above, the contact portion 1004 a of the slot electrical contact 1004 has elasticity and can be displaced, and the displacement direction is substantially parallel to the thickness direction of the card medium 1. That is, in FIG. 13D, the contact portion 1004a contacts the card electrical contact 505 and is displaced upward, and a contact reaction force (contact reaction force) 1303 is generated in the downward direction at the displaced position. Keep state.

  Considering the looseness of fitting and the like, if a predetermined displacement stroke is given to the contact portion 1004a to generate the contact reaction force 1303, the reliability as an electrical contact can be improved. Here, the direction of the contact reaction force 1303 of the contact portion 1004a and the heat receiving portion reaction force (biasing force) 1302 are substantially orthogonal.

  As described above, although the position of the card medium 1 is fixed in the inserted state, some backlash occurs when the dimensional variation is taken into consideration. That is, a positioning error occurs. The play of the card medium 1 is shifted to the removal direction by the heat receiving portion reaction force 1302. On the other hand, since the contact reaction force 1303 is orthogonal to the heat receiving portion reaction force 1302, even if play occurs in the card medium 1, the displacement stroke is not affected. Therefore, the contact reaction force 1303 does not change. Therefore, even if the insertion position of the card medium 1 is loose, the contact pressure between the contacts can be kept stable.

  FIG. 15 is a perspective view showing an appearance of a card type recording apparatus (card medium) 15 according to another embodiment, which is different from the card medium 1 according to the above-described embodiment. FIG. 15A is a perspective view of the card medium 15 as viewed from the second surface side, and FIG. 15B is a perspective view of the card medium 15 as viewed from the first surface side facing the second surface.

  FIG. 16 is a diagram for explaining an insertion state of the card medium 15 according to another embodiment shown in FIG. FIG. 16A is a plan view showing the insertion of the card medium, and FIG. 16B is a sectional view taken along line B3-B3 shown in FIG. Moreover, FIG.16 (d) is sectional drawing along the A3-A3 line shown to Fig.16 (a). 15 and FIG. 16, the same reference numerals are given to the same components as those shown in FIG. 1 and FIG.

  As shown in FIG. 16C, the controller IC 402 provided in the card medium 15 is mounted on the surface of the card substrate 1502 on the slot substrate 1003 side in the inserted state. Compared with the card substrate 502 provided in the card medium 1, the controller IC 402 is mounted on the opposite surface (see FIG. 13D). In other words, when viewing the insertion position, the first surface on which more heat sources are arranged is the surface 1501 on the side facing the slot substrate 1003, and is the surface opposite to the first surface 101 of the card medium 1. The second surface is a surface 1507 facing the slot cover 1002 in the inserted state.

  As described above, the present invention can be applied even if the first surface on which the heat sources concentrate differs from the card medium 1.

  As shown in FIGS. 15B and 16B, heat transfer surfaces 1505 and 1506 are formed from the first surface card exterior 1503 defining the first surface 1501 to the terminal surface 1504. As a result, the heat transfer surfaces 1505 and 1506 come into contact with the heat receiving portions 1008 and 1009 to conduct heat.

  FIG. 17 is a perspective view showing the external appearance of a card type recording apparatus (card medium) 17 according to another embodiment, which is different from the card medium 1 according to the above-described embodiment. FIG. 17A is a perspective view of the card medium as viewed from the second surface side, and FIG. 17B is a perspective view of the card medium as viewed from the first surface side facing the second surface.

  The illustrated card medium 17 has a card connector structure different from that of the card type recording device 15. The card connector 1701 has a card electrical contact 1707 exposed along the side on the first surface 1702. In general, since the electrical contact of the slot is disposed in the deep part of the slot, the end surface on the side along which the card electrical contact 1707 extends also in the card medium 17 becomes the end surface in the insertion direction. That is, it can be regarded as the terminal surface 1705.

  Similarly to the card medium 1 and the card medium 15, heat transfer surfaces 1703 and 1704 are formed from the first surface card exterior 1706 defining the first surface 1702 toward the terminal surface 1705. Thereby, heat can be conducted to the heat receiving portions corresponding to the heat transfer surfaces 1703 and 1704.

  As described above, in the embodiment of the present invention, heat is conducted to the contact surface (contact portion) of the surface contact slot on the end surface on the electrical contact side of the card medium, so that the heat dissipation path is redundant. Therefore, it is possible to efficiently dissipate heat.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to these embodiment, Various forms of the range which does not deviate from the summary of this invention are also contained in this invention. .
