JP2012-23131A Japanese Patent No. 4962871

  In the prior art disclosed in Patent Document 1 described above, in the state where the card type recording device is inserted and the cover unit is closed, the heat of the card type recording device can be dissipated, but the user opens the cover unit, During the operation of taking out the card type recording apparatus, it is difficult to effectively dissipate the heat of the card type recording apparatus because there is no heat dissipation path. For this reason, the temperature of the card type recording apparatus does not sufficiently decrease until the user touches, and the user may feel uncomfortable.

  Further, in the prior art disclosed in Patent Document 2, it is possible to dissipate heat even when the card type recording apparatus is discharged because the thin metal plate for heat dissipation always contacts the card type recording apparatus and radiates heat. Since a frictional force is generated between the mold recording apparatus and the thin metal plate, there is a possibility that the feeling of operation when the card type recording apparatus is attached or detached is lowered.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a means capable of sufficiently dissipating heat even when a card type recording apparatus is taken out without impairing the operational feeling when the card type recording apparatus is attached or detached.

  In order to achieve the above, an electronic device of the present invention is an electronic device in which a recording medium can be attached and detached, and a discharge mechanism for taking out the recording medium, a first heat radiating portion, and a second heat radiating portion, The discharging mechanism includes a pressing member that presses the recording medium in the discharging direction, and a driving member that moves in a direction different from the pressing member in response to a user operation and drives the pressing unit. The first heat radiating part is in contact with the pressing member when the recording medium is inserted, and the second heat radiating member is at least during the discharging operation of the recording medium. It contacts the drive member.

  According to the present invention, it is possible to lower the temperature of the card type recording apparatus until just before the user touches the card type recording apparatus without impairing the operational feeling when the card type recording apparatus is attached or detached.

Reference numeral 48 denotes an ejector heat dissipating part attached to the cover 1a of the camera 1, and when the user performs an operation of ejecting the card type recording apparatus 5, it contacts the ejector 47 and transfers heat.

  Details of this will be described later. 50 is an arrow indicating the direction when the card type recording device 5 is inserted into the slot 30, 51 is a top surface of the card type recording device, 52 is a card connector portion of an electrical contact provided in the card type recording device, Reference numeral 55a denotes a card left side guide portion provided on the left side of the card, and 56a denotes a card right side guide portion provided on the right side of the card. Reference numeral 59 denotes a heat radiating unit, which is thermally connected to internal elements (the power supply IC 27, the controller 28, and the flash memory 29) of the card type recording apparatus 5.

  The slot 31 includes a slot base 42, a slot electrical contact 43 press-fitted into the slot base 42, a card heat radiating member 44 fixed to the slot base 42, and a slot cover 45 engaged with the slot base 42.

  The slot base 42 is formed of a molded product of LCP (liquid crystal polymer) from the viewpoints of heat resistance that can withstand reflow, thinness for making a small and thin shape, molten metal flow that can create a complicated shape, and slidability. Yes. The slot electrical contact 43 is formed of phosphor bronze appropriately plated (gold plating or the like) from the viewpoints of springiness for appropriately bringing the contact into contact, solder wettability, contact electrical resistance, and the like. The card heat radiating member 44 is made of pure copper or a copper alloy that is appropriately plated (such as hard chrome plating) from the viewpoint of thermal conductivity, wear resistance, and the like. The slot cover 45 is formed of stainless spring steel from the viewpoint of thinness, workability, corrosion resistance, and the like.

  The card type recording apparatus 5 is inserted in the direction of the arrow 50 while being roughly positioned by the slot cover 45 (guided with a lot of backlash). Thereafter, a card left side guide portion 55a provided in the card type recording apparatus 5, a slot left side guide portion 42b provided on the slot base 42, and a card right side guide portion 56a provided in the card type recording apparatus 5 After being positioned more precisely by the slot right side guide part 42c provided on the slot base 42, it is inserted to a communicable position. Finally, it is inserted to a position where a card pressing portion 471 (to be described later) and a heat radiating portion 59 on the card type recording apparatus 5 come into contact. At this position, the card connector 52 of the card type recording apparatus 5 is inserted into the slot connector 42a for a predetermined length, and stable communication is possible.

  Next, the detailed configuration of the eject mechanism 47 will be described with reference to FIG. The eject mechanism 47 includes a card pressing portion 471, a rotating portion 472, and a slide portion 473. The card pressing part 471 is provided with card contact parts 471c at two locations, and comes into contact with the card type recording apparatus 5 at the position of the heat radiating part 59 provided in the card type recording apparatus 5. As described above, since the internal element of the card type recording apparatus 5 and the heat radiating part 59 are thermally connected, the heat generated inside the card is transferred to the card pressing part 471 via the heat radiating part 59 and the card contact part 471c. Communicated.

  The rotating portion 472 is rotatably engaged with a rotating shaft 45a provided on the slot cover 45 by an opening 472a. Further, the engaging portion 472b engages with the engaging shaft 471b on the card pressing portion 471. As a result, the rotation portion 472 rotates about the rotation shaft 45a, and the rotation operation is transmitted through the engagement shaft 471b. Therefore, the card pressing portion 471 can advance and retreat in the card insertion / removal direction. Further, as described above, since the heat of the card type recording device 5 is transmitted to the card pressing portion 471, this heat is transmitted to the rotating portion 472 via the engaging shaft 471b. Further, the rotating part 472 is provided with a contact heat radiating part 472c. When the rotating part 472 rotates, it contacts the ejector heat radiating component 48 to radiate heat from the card type recording apparatus. As will be described later, the heat transmitted to the heat radiation component 48 is radiated to the cover 1a of the camera.

  The slide portion 473 is slidably held in the card insertion / removal direction with respect to the slot cover 45, an eject button 46 operated by the user is disposed at one end, and a slide engagement portion 473d that engages with the rotation portion 472 is disposed at the other end. Is provided. The slide engagement portion 473d engages with a slide engagement claw 472d provided in the rotation portion 472, and transmits the slide operation of the slide member 473 to the rotation portion 472. With this configuration, when the user presses the eject button 46, the slide portion 473 slides, and the rotation portion 472 rotates by the operation, and the card pressing portion 471 moves in the card ejection direction. The card can be ejected.

  As described above, since the card connector portion 52 of the card type recording device 5 is in contact with the slot connector portion 42a for a predetermined length, the card type recording device 5 starts moving when the eject button 46 is pressed. Until this length is moved, a frictional force is generated between the card connector portion 52 and the slot connector portion 42a, and the user needs to press the eject button 46 with a force exceeding the friction force. Accordingly, the operational feeling of the eject button 46 when the card is ejected is heavy from the start of pressing to a predetermined stroke, but suddenly becomes lighter from the middle.

  Next, with reference to FIG. 5 and FIG. 6, the heat radiation structure when the card type recording apparatus is inserted and discharged will be described. FIG. 5A is a view of the slot 31 into which the card type recording device 5 is inserted as viewed from the lateral direction of the camera, and FIG. 5B is a cross-sectional view taken along the line AA shown in the figure.

  The heat generated inside the card type recording device 5 is transmitted to the heat radiating unit 59. As shown in FIG. 5, in the card insertion state, the heat radiating part 59 abuts on the card contact part 471 c on the card pressing part 471. The card contact portion 471c is in contact with the card heat radiation member 44, and the card heat radiation member 44 is fastened to the heat transfer means 15 together with the slot substrate 41 and the slot base 42 by screws 441. With this configuration, the heat generated in the internal element of the card type recording apparatus 5 is first transmitted from the heat radiating portion 59 to the card contact portion 471c on the card pressing portion 471, and from there, the card heat radiating member 44, the screw. Heat is transferred through the contact points in the order of 441 and finally reaches the heat transfer means 15. As described above, since the heat transfer means 15 diffuses heat inside the camera 1, the generated heat is effectively diffused inside the camera when the card type recording device 5 is inserted, and the card type recording device. 5 can be suppressed.

  FIG. 6 is a view showing a state in which the card type recording apparatus 5 is being discharged from the same direction as FIG. When the user presses the eject button 46 in the arrow B direction, the slide portion 473 slides and the rotation portion 472 rotates as described above, and the card pressing portion 471 is driven in the card ejection direction (arrow C direction). As a result, the card type recording member 5 moves in the discharging direction. When the eject button 46 is pushed down to the limit where the slide part 473 can slide, the ejection operation of the card type recording apparatus 5 is completed, and the user can easily take out the card type recording apparatus 5 protruding from the slot 31.

FIG. 6 shows a state where the card type recording apparatus 5 is moving, that is, a state where the eject button is not pressed to the limit. Hereinafter, a configuration for radiating heat generated in the card type recording apparatus 5 in this state will be described.
As described above, the heat generated in the internal element of the card type recording apparatus 5 is transmitted to the heat radiating unit 59.

  Even in the card ejection state as shown in FIG. 6, the card pressing portion 471 is always in contact with the heat radiating portion 59 at the card contact portion 471c. For this reason, the heat of the card type recording apparatus 5 is transmitted to the card pressing portion 471. On the other hand, in this state, the card pressing portion 471 moves and is not in contact with the card heat radiating member 44. Therefore, the heat flowing into the card pressing portion 471 cannot be released from the card heat radiation member 44 to the heat transfer means 15 through the screw 441.

  The heat transmitted to the card pressing part 471 is transmitted from the engaging shaft 471b on the card pressing part 471 to the rotating part 472 via the engaging part 472b. Then, heat is radiated to the ejector heat radiating portion 48 by the contact heat radiating portion 472 c provided in the rotating portion 472. The ejector heat radiating section 48 is disposed on a locus along which the contact heat radiating section 472c is moved by the rotation of the rotating section 472. When the eject button 46 is pushed in a predetermined length as shown in FIG. It comes into contact with the portion 472c. Since the ejector heat radiating portion 48 is made of metal and has a leaf spring shape, it can be deformed as indicated by 48 a as the contact heat radiating portion 472 moves.

  Further, the ejector heat radiating portion 48 is fixed to the cover 1 a of the camera 1 with a screw 481. FIG. 6 shows only the vicinity of the fixing portion of the cover 1a. With such a configuration, the contact heat radiation part 472c of the rotating part 472 contacts the ejector heat radiation part 48 from the middle of the discharge operation of the card type recording apparatus 5, and the contact heat radiation part 472c is completed until the card discharge operation is completed. The state where the ejector heat radiation part 48 is in contact can be maintained.

  Thereby, even during the card ejection operation, the heat of the card type recording apparatus 5 is transmitted from the contact heat radiation part 472c to the cover 1a of the camera 1 via the ejector heat radiation part 48. Since the heat transfer means 15 that has released heat when the card type recording device 5 is inserted is located inside the camera 1, the temperature is likely to rise. On the other hand, since the cover 1a is in contact with the outside air, the temperature hardly rises, and the transmitted heat is immediately released to the outside air, so that the temperature of the card type recording member can be effectively lowered. In general, the card-type recording device 5 tends to rise in temperature during use, for example, for writing photographing data.

  For this reason, when the user takes out the card type recording apparatus 5, if the temperature is not sufficiently lowered, the user may feel uncomfortable. In the configuration of the present embodiment, the heat of the card type recording device 5 can be radiated until the discharging operation immediately before the user touches the card type recording device, thus reducing the possibility of giving the user a sense of incongruity as described above. be able to.

  Further, as indicated by 48a, when the ejector heat radiating portion 48 is deformed as the rotating portion 472 moves, a reaction force acts on the rotating portion 472, so that the moving speed of the 472 decreases, and the user operates A force opposite to the pressing direction is generated in the eject button 46 that is being pressed. If the increase in the operating force due to the reaction force of the ejector heat radiating portion 48 is added to the frictional force between the card connector portion 52 and the slot connector portion 42a described above, the force required for the eject operation increases.

  Therefore, in this embodiment, after the card-type recording device 5 moves a predetermined distance and the card connector portion 52 and the slot connector portion 42a are not in contact with each other, the contact heat radiation portion 472c of the rotating portion 472 is ejected by the ejector. It is configured to initiate contact with part 48. With such a configuration, it is possible to radiate heat from the eject mechanism 47 while preventing an increase in operating force.

  Further, after the card connector portion 52 is no longer frictioned, the ejector heat radiating portion 48 generates a force in the eject mechanism 47 again in the direction of obstructing the card ejection, so that the moving speed of the card pressing portion 471 is suppressed, and the eject button 47 It is possible to prevent the card type recording device 5 from jumping out of the slot 31 when is pushed.

(Example 2)
A second embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the structure similar to 1st Embodiment, and detailed description is abbreviate | omitted. FIG. 7 is a diagram showing a state equivalent to FIG. 5 in the second embodiment. The difference from the first embodiment is in the shape of a notch 451 and a rotation part 472 provided in the slot cover 45. The distance between the distal end portion 472d and the engaging portion 472b in the rotation operation around the opening 472a is longer than that in the first embodiment. Further, the notch 451 is larger than that of the first embodiment. Other configurations are the same as those in FIG.

  FIG. 8 is a diagram showing a state equivalent to that of FIG. 6 with respect to the second embodiment. When the user presses the eject button 46, the rotation unit 472 rotates about the opening 472a. The leading end 472d passes through a notch 451 provided in the slot cover 45, moves to a position indicated by a broken line in the figure, and contacts the top surface 51 of the card type recording apparatus 5. Accordingly, the heat of the card type recording device 5 is directly transmitted to the rotating portion 472 through the top surface 51. Even in this state, a heat transfer path from the heat radiating portion 59 of the card type recording apparatus 5 to the rotating portion 472 through the card pressing portion 471 is also secured as in the first embodiment. Similarly, the contact heat dissipating part 472 c on the rotating part 472 contacts the ejector heat dissipating part 48.

  By adopting such a configuration, the heat of the card-type recording member 5 can be transmitted through two paths: a path where the rotating part 472 contacts the top surface 51 and a path reaching the rotating part 472 via the card pressing part 471. Since heat can be transmitted to the ejector heat radiating portion, the temperature of the card type recording device 5 can be effectively reduced.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
