Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments will be described in detail with reference to the drawings as appropriate. However, overly detailed explanations may be omitted. For example, detailed explanations of well-known matters and redundant explanations for substantially the same configurations may be omitted. This is to avoid making the following explanations unnecessarily redundant and to facilitate the understanding of those skilled in the art.

[0011] Note that the inventor(s) provide the accompanying drawings and the following description so that those skilled in the art can fully understand the present disclosure, and do not intend to limit the subject matter described in the claims thereby.

[0012] The imaging apparatus according to the embodiments of this disclosure will be described below with reference to the drawings.

[0013] (Embodiment 1) Figure 1 is a schematic perspective view of an imaging device according to Embodiment 1 of this disclosure.

[0014] The XYZ Cartesian coordinate system shown in the figure is provided to facilitate understanding of the embodiments of this disclosure and does not limit the embodiments of this disclosure. The X-axis direction is the front-to-back direction of the imaging device, the Y-axis direction is the left-to-right direction, and the Z-axis direction is the height direction. In this specification, the side of the imaging device where the subject is located is referred to as the "front side," and the side where the imaging device is located is referred to as the "rear side." Furthermore, the "left side" and "right side" of the imaging device refer to the "left side" and "right side" when the imaging device is viewed from the front, that is, when the imaging device is viewed from the subject side.

[0015] As shown in Figure 1, the imaging device 10 according to this embodiment has a housing 12. The housing 12 includes a front surface 12a that faces the subject during shooting, a rear surface 12b opposite to the front surface 12a, and an upper surface 12c, a left side surface 12d, and a right side surface 12e that connect the front surface 12a and the rear surface 12b.

[0016] The front surface 12a of the housing 12 is provided with a lens mount 14 to which a lens (not shown) can be detachably attached. The rear surface 12b of the housing 12 is provided with a vari-angle monitor (not shown) that is movable relative to the housing 12. The top surface 12c of the housing 12 is provided with a shutter button 16, a dial 18, and the like.

[0017] Furthermore, the imaging device 10 is configured to have a detachable recording medium for recording captured images and video data.

[0018] Figure 2A is a perspective view of a portion of the imaging device just before the recording medium is inserted. Figure 2B is a perspective view of a portion of the imaging device with the recording medium inserted.

[0019] As shown in Figures 2A and 2B, in this embodiment 1, the recording medium 100 that is detachably mounted on the imaging device 10 is a card-shaped recording medium, such as a CFE (CompactFlash Express) card (registered trademark). The recording medium 100 is a rectangular thin plate and has opposing main surfaces 100a and 100b and four end surfaces 100c, 100d, 100e, and 100f. The main surfaces 100a and 100b are the planes with the largest area on the recording medium 100. The recording medium 100 is inserted into the housing 12 of the imaging device 10 in the direction opposite to the end surfaces 100c and 100d (Y-axis direction).

[0020] As shown in Figures 2A and 2B, the recording medium 100 is inserted into the imaging device 10 with its main surfaces 100a and 100b facing in the front-to-back direction (X-axis direction) of the imaging device 10, with the main surfaces 100a and 100b facing in the left-to-right direction (Y-axis direction) of the imaging device 10. For this purpose, an input slot 12f into which the recording medium 100 is inserted is provided on the left side 12d of the housing 12 of the imaging device 10.

[0021] Furthermore, the imaging device 10 has a cover 20 that selectively covers the input slot 12f of the housing 12, thereby opening and closing the input slot 12f. When the input slot 12f is closed by being covered by the cover 20, the recording medium 100 cannot be inserted into the input slot 12f. Figure 2A shows a state in which the cover 20 is separated from the input slot 12f and does not cover the input slot 12f, i.e., the input slot 12f is open, allowing the recording medium 100 to be inserted into the input slot 12f.

[0022] Figure 2C is a perspective view of a portion of the imaging device showing the state before the outer cover of the cover slides open. Figure 2D is a perspective view of a portion of the imaging device showing the state after the outer cover of the cover has slid open and the cover is closing the input slot. Figure 3 is an exploded perspective view of a portion of the imaging device including the cover.

[0023] In this embodiment 1, as shown in Figure 3, the cover 20 is supported on the housing 12 so as to be rotatable about a rotation centerline CL that extends in the height direction (Z-axis direction) of the imaging device 10. Specifically, the cover 20 is supported via a shaft 24 that extends in the height direction so as to be rotatable with respect to a left casing 22 which is a part of the housing 12 and includes the left side surface 12d.

[0024] Furthermore, in this embodiment 1, as shown in Figures 2A and 3, the cover 20 includes an inner cover 26 supported on a shaft 24 so as to be rotatable about a rotational centerline CL, an outer cover 28 supported on the inner cover 26 so as to be slidable in a direction intersecting the extending direction (Z-axis direction) of the rotational centerline CL, and a locking member 30 that locks the outer cover 28 to the inner cover 26 so as not to slide.

[0025] Furthermore, in this embodiment 1, the cover 20 is biased by the torsion spring 31. Specifically, as shown in Figures 2A and 2B, the cover 20 is biased by the torsion spring 31 so that it remains separated from the input opening 12f, allowing the recording medium 100 to be inserted into the input opening 12f.

[0026] As shown in Figure 2D, when the cover 20 is closed over the input port 12f, the engaging claw 28a provided on the outer cover 28 of the cover 20 (shown in Figure 3) engages with the engaging recess 22a provided on the left casing 22 of the housing 12. This allows the cover 20 to continue covering the input port 12f against the biasing force of the torsion spring 31. Engaging and disengaging the engaging claw 28a and the engaging recess 22a is performed by sliding the outer cover 28 relative to the inner cover 26 in the front-to-back direction (X-axis direction) of the imaging device 10, as shown in Figure 2C.

[0027] With such a cover 20, as shown in Figures 2A and 2B, first, the recording medium 100 is inserted into the input slot 12f of the housing 12, with the cover 20 separated and open. After the recording medium 100 is inserted into the input slot 12f, as shown in Figure 2C, the cover 20 rotates to cover the input slot 12f. Subsequently, as shown in Figure 2D, the cover 20 closes the input slot 12f by sliding the outer cover 28. Then, the locking member 30 moves, locking the outer cover 28 against the inner cover 26 so that it cannot slide, and as a result, the cover 20 continues to close the input slot 12f.

[0028] Furthermore, the imaging device 10 is configured to cool the recording medium 100. The configuration for this will be described below.

[0029] Figure 4 is an exploded perspective view of a portion of an imaging device, including components related to the cooling of the recording medium.

[0030] As shown in Figure 4, the imaging device 10 has a connector 32 inside its housing 12 into which the recording medium 100 inserted into the input slot 12f of the housing 12 is inserted. In this embodiment 1, the connector 32 is mounted on a substrate 34. Specifically, the connector 32 includes a box-shaped connector frame 36 and terminals (not shown) provided on the connector frame 36 that electrically connect to the recording medium 100. The recording medium 100 is detachably inserted into the space formed between the substrate 34 and the connector frame 36 in the left-right direction (Y-axis direction) of the imaging device 10. Furthermore, by inserting the recording medium 100 into the connector frame 36 of the connector 32, an electrical connection between the terminals of the connector 32 and the terminals (not shown) of the recording medium 100 is maintained. For this purpose, the connector frame 36 is provided with a leaf spring 36a that biases the recording medium 100 toward the substrate 34 and maintains the electrical connection of these terminals.

[0031] Furthermore, in this embodiment 1, the connector frame 36 is provided with a notch 36b that exposes a portion of the recording medium 100 when it is inserted into the connector 32.

[0032] Figure 5 is a perspective view of a portion of the connector with a storage medium inserted.

[0033] As shown in Figure 5, the notch 36b provided in the connector frame 36 of the connector 32 exposes a portion of the recording medium 100, specifically most of the main surface 100a. The heat-absorbing member 38 shown in Figure 4 makes contact with this exposed portion of the recording medium 100.

[0034] Figure 6 is a cross-sectional view of a portion of the imaging device around the connector, with the cover sealing the input opening and the heat-absorbing member in contact with the recording medium. Figure 6 corresponds to Figure 2D. In Figure 6, some components, such as the inner cover 26, are omitted from the illustration.

[0035] As shown in Figures 4 and 6, in this embodiment 1, the heat-absorbing member 38 is a strip-shaped heat-conducting sheet, for example, a graphite sheet having high thermal conductivity.

[0036] One end 38a of the heat-absorbing member 38 directly contacts the recording medium 100 inserted into the connector 32. Specifically, the heat-absorbing member 38 contacts the portion of the recording medium 100 (main surface 100a) exposed through the notch 36b of the connector frame 36. Alternatively, a through hole may be provided in the connector frame 36 instead of the notch 36b.

[0037] In this first embodiment, the other end 38b of the heat-absorbing member 38 is fixed to the heat-dissipating member 40 provided inside the housing 12. For example, the heat-absorbing member 38 is fixed to the heat-dissipating member 40 via an adhesive or double-sided tape (not shown) with high thermal conductivity.

[0038] In this embodiment 1, the heat dissipation member 40 is provided inside the housing 12. A heat sink 42 with multiple fins is attached to the heat dissipation member 40. Furthermore, a fan 43 for cooling the heat sink 42 is provided inside the housing 12.

[0039] With such a heat-absorbing member 38, the heat generated in the recording medium 100 can be transferred to the heat-dissipating member 40. Specifically, the heat-absorbing member 38 absorbs heat from the heat source in the recording medium 100 and transfers the absorbed heat to the heat-dissipating member 40.

[0040] Figure 7 is an exploded perspective view showing a heat source within a recording medium where heat is absorbed by a heat-absorbing component.

[0041] As shown in Figure 7, the recording medium 100 includes a case 102, a substrate 104 housed within the case 102, and a controller chip 106 and a memory chip 108 mounted on the substrate 104. A metal plate 110, which is part of the case 102 and constitutes most of the main surface 100a, is in contact with the controller chip 106 and the memory chip 108 via thermal conductive grease (not shown).

[0042] For example, the imaging device 10 performs video recording while recording the video recording data to the recording medium 100 via the connector 32. In this case, if the video recording is for a long time and / or the recorded video is high resolution, the recording medium 100 continues to generate heat. Specifically, as shown in Figure 7, heat sources such as the controller chip 106 and memory chip 108 built into the case 102 of the recording medium 100 continue to generate heat. One end 38a of the heat-absorbing member 38 absorbs the heat from these heat sources of the recording medium 100 via the metal plate 110 of the case 102. The absorbed heat is transferred to the heat-dissipating member 40 via the other end 38b of the heat-absorbing member 38. The heat-dissipating member 40 is then forcibly cooled by the fan 43 via the heat sink 42.

[0043] As shown in Figure 7, the heat-absorbing member 38 makes direct surface contact with the main surface 100a, which is the largest surface area within the recording medium 100, in a direction (X-axis direction) intersecting the insertion direction (Y-axis direction) of the recording medium 100. In this case, it is desirable that as much of the heat-absorbing member 38 as possible be positioned as close as possible to the heat-generating controller chip 106 and memory chip 108. That is, by maximizing the overlapping area between the heat-absorbing member 38 and the controller chip 106 and memory chip 108 in the contact direction (X-axis direction), the heat-generating sources of the recording medium 100 can be cooled with high cooling efficiency.

[0044] Furthermore, if the entire or a portion of the housing 12 is made of metal, the metal portion of the housing 12 and the heat dissipation member 40 may be directly connected. Alternatively, the metal portion of the housing 12 may be the heat dissipation member 40. In this case, the heat from the heat dissipation member 40 is dissipated to the outside of the housing 12.

[0045] The heat-absorbing member 38 is also provided within the housing 12 so as to be movable in a direction (X-axis direction) intersecting the insertion direction (Y-axis direction) of the recording medium 100, in order to move away from or in contact with the recording medium 100.

[0046] Specifically, the position of the heat-absorbing member 38 is changed based on the state of the cover 20.

[0047] Figure 8 is a cross-sectional view of a portion of the imaging device around the connector when the recording medium is being inserted into the connector. Figure 9 is a cross-sectional view of a portion of the imaging device around the connector when the insertion of the recording medium into the connector is complete and the cover covers the input slot. Figure 8 corresponds to Figures 2A and 2B, and Figure 9 corresponds to Figure 2C. In Figures 8 and 9, some components such as the inner cover 26 are omitted from the illustration.

[0048] As shown in Figures 6, 8, and 9, in this embodiment 1, the heat-absorbing member 38 is supported by a support member 44. In this embodiment 1, the support member 44 is a cantilever-shaped member that extends in the insertion direction (Y-axis direction) of the recording medium 100 and is capable of bending deformation. The support member 44 also has a free end 44a that is movable in a direction intersecting the insertion direction (Y-axis direction) of the recording medium 100 (X-axis direction), and a fixed end 44b that is fixed to the heat-dissipating member 40. One end 38a of the heat-absorbing member 38 is fixed to the free end 44a of the support member 44 via an elastic member 46 such as a sponge. When the support member 44 deforms (i.e., the free end 44a moves), the heat-absorbing member 38 moves, and one end 38a of the heat-absorbing member 38 moves away from or into contact with the recording medium 100.

[0049] The position of the free end 44a of the support member 44 that supports one end 38a of the heat-absorbing member 38 is changed by the interlocking member 28b. In this embodiment 1, as shown in Figure 2A, the interlocking member 28b is a rib-shaped projection provided on the outer cover 28 of the cover 20, that is, a part of the outer cover 28.

[0050] Specifically, as shown in Figures 2A, 2B, and 8, when the cover 20 is separated and the input slot 12f is open so that the recording medium 100 can be inserted into the input slot 12f, the interlocking member 28b provided on the outer cover 28 of the cover 20 is separated from the free end 44a of the support member 44. Therefore, the support member 44 is in its natural state and is not deformed by bending. As a result, one end 38a of the heat-absorbing member 38 supported by the support member 44 is separated from the recording medium 100 when it is inserted into the connector 32.

[0051] As shown in Figures 2C and 9, even when the cover 20 covers the input opening 12f but the outer cover 28 has not yet slid relative to the inner cover 26, the interlocking member 28b provided on the outer cover 28 of the cover 20 is separated from the free end 44a of the support member 44. Therefore, the support member 44 is in its natural state and is not deflected or deformed. As a result, one end 38a of the heat-absorbing member 38 supported by the support member 44 is separated from the recording medium 100 when it is inserted into the connector 32.

[0052] As shown in Figures 2C and 9, when the outer cover 28 slides relative to the inner cover 26 with the cover 20 covering the input opening 12f, the interlocking member 28b provided on the outer cover 28 contacts the free end 44a of the support member 44. After contact, as the outer cover 28 slides further, the support member 44 is bent and deformed by the interlocking member 28b, and its free end 44a moves toward the recording medium 100 which is inserted into the connector 32. Finally, as shown in Figure 6, one end 38a of the heat-absorbing member 38 supported by the free end 44a of the support member 44 contacts the recording medium 100. After contact, the elastic member 46 deforms, and the heat-absorbing member 38, which is a heat-conducting sheet, makes surface contact with the recording medium 100 in a tight-fitting state.

[0053] Therefore, as shown in Figures 2A, 2B, and 8, when the cover 20 is separated and the input port 12f is open due to the interlocking member 28b, one end 38a of the heat-absorbing member 38 is positioned away from the recording medium 100. Also, as shown in Figures 2D and 6, when the input port 12f is closed by being covered by the cover 20 due to the interlocking member 28b (i.e., when the engaging claw 28a of the outer cover 28 is engaged with the engaging recess 22a of the left casing 22), the free end 38a of the heat-absorbing member 38 is positioned to remain in contact with the recording medium 100.

[0054] With this interlocking member 28b, as shown in Figure 8, when the cover 20 is separated and the input port 12f is open, the heat-absorbing member 38 is not in contact with the recording medium 100. Therefore, the recording medium 100 can be easily removed from the connector 32. Also, as shown in Figure 6, when the input port 12f is closed and covered by the cover 20, the recording medium 100 is not removed from the connector 32, so the heat-absorbing member 38 continues to be in contact with the recording medium 100. As a result, the recording medium 100 continues to be cooled (heat removed) via the heat-absorbing member 38.

[0055] According to this embodiment 1 described above, in an imaging device 10 in which a card-shaped recording medium 100 is detachably mounted, the cooling performance for the recording medium 100 can be improved.

[0056] (Embodiment 2) This second embodiment differs from the first embodiment described above in terms of the heat transfer path from the recording medium to the heat dissipation member. Therefore, this second embodiment will be described focusing on the differences.

[0057] Figure 10 is a schematic cross-sectional view of a portion of the imaging device around the connector according to Embodiment 2.

[0058] As shown in Figure 10, in the imaging device according to this second embodiment, the heat-absorbing member 238 that contacts the recording medium 100 is made of a material with high thermal conductivity, such as a metal material, and is supported by a cantilevered support member 244. The heat from the recording medium 100 is transferred to the heat-dissipating member 240 via the heat-absorbing member 238 and the support member 244. For this purpose, the fixed end 244b of the support member 244 is fixed to the heat-dissipating member 240. In particular, the heat-dissipating member 240 and the support member 244 are integrated as a single component.

[0059] The outer cover 128 of the cover 120 is provided with an interlocking member 128b, similar to the outer cover 28 of the first embodiment described above. When the outer cover 128 of the cover 120 slides, the interlocking member 128b provided on the outer cover 128 contacts the free end 244a of the support member 244, causing the free end 244a to move. As a result, the heat-absorbing member 238 provided on the support member 244 comes into contact with the recording medium 100. In this second embodiment, the connector frame 236 of the connector 232 has a through hole 236b that exposes a portion of the recording medium 100. The heat-absorbing member 238 comes into contact with the recording medium 100 through this through hole 236b.

[0060] Similar to Embodiment 1 described above, this second embodiment also improves the cooling performance of the recording medium 100 in an imaging device in which a card-shaped recording medium 100 is detachably mounted.

[0061] (Embodiment 3) This third embodiment is a modification of the second embodiment described above. Therefore, this third embodiment will be described focusing on the differences. Also, components that are substantially the same as those in the second embodiment described above are denoted by the same reference numerals.

[0062] Figure 11 is a schematic cross-sectional view of a portion of the imaging device around the connector according to Embodiment 3.

[0063] As shown in Figure 11, in the imaging device according to this third embodiment, a through-hole 334a is formed in the substrate 334, rather than in the connector frame 336 of the connector 332, to expose a portion of the recording medium 100. The heat-absorbing member 238, supported by the support member 244, contacts the recording medium 100 inserted into the connector 332 through the through-hole 334a in the substrate 334.

[0064] This third embodiment, like the first embodiment described above, can improve the cooling performance of the recording medium 100 in an imaging device in which a card-shaped recording medium 100 is detachably mounted.

[0065] (Embodiment 4) This fourth embodiment differs from the third embodiment described above in terms of the support member that supports the heat-absorbing member. Therefore, this fourth embodiment will be described focusing on the differences. Also, components that are substantially the same as those in the third embodiment described above are given the same reference numerals.

[0066] Figure 12 is a schematic cross-sectional view of a portion of the imaging device around the connector according to Embodiment 4.

[0067] As shown in Figure 12, in the imaging device according to this fourth embodiment, the support member 444 is not a cantilevered member that deforms by bending, but a lever-shaped member. Specifically, the support member 444 has one end 444a that contacts an interlocking member 128b provided on the outer cover 128 of the cover 120, and the other end 444b that rotates. The heat-absorbing member 438 is supported by such a support member 444 via an elastic member 446 such as a spring. The heat-absorbing member 438 is also thermally connected to the heat-dissipating member 440 via a deformable heat-transfer member 448, such as a metal wire. The heat-transfer member 448 may be a heat-conducting sheet used as the heat-absorbing member 38 in the first embodiment described above.

[0068] This embodiment 4, like the embodiment 1 described above, can improve the cooling performance of the recording medium 100 in an imaging device in which a card-shaped recording medium 100 is detachably mounted.

[0069] (Embodiment 5) This embodiment 5 differs from embodiment 4 described above in terms of the support member that supports the heat-absorbing member. Therefore, this embodiment 5 will be described focusing on the differences. Also, components that are substantially the same as those in embodiment 4 described above are denoted by the same reference numerals.

[0070] Figure 13 is a schematic cross-sectional view of a portion of the imaging device around the connector according to Embodiment 5.

[0071] As shown in Figure 13, in the imaging device according to this embodiment 5, the support member 544 differs from the lever-shaped support member 444 of the embodiment 4 described above in the image capture device, and is a sliding member that moves parallel to the recording medium 100. The interlocking member 128b of the sliding outer cover 128 contacts one end 544a of the support member 544, causing the entire support member 544 to move parallel to the recording medium 100. Due to this parallel movement of the support member 544, the heat-absorbing member 438, which is supported by the support member 544 via the elastic member 446, approaches and contacts the recording medium 100.

[0072] This embodiment 5, like the embodiment 1 described above, can improve the cooling performance of the recording medium 100 in an imaging device in which a card-shaped recording medium 100 is detachably mounted.

[0073] Although embodiments of this disclosure have been described above with reference to several embodiments, the embodiments of this disclosure are not limited to these.

[0074] For example, in the first embodiment described above, the cover 20 is rotatably supported by the housing 12 and consists of an inner cover 26 and an outer cover 28 that slides relative to the inner cover 26. However, the cover according to the embodiments of this disclosure is not limited thereto. For example, the cover may be a sliding cover that is detachably provided with respect to the housing and moves parallel to a direction intersecting the insertion direction of the recording medium into the connector.

[0075] Furthermore, in the first embodiment described above, the heat-absorbing member 38 that directly contacts the recording medium 100 and absorbs heat from the recording medium 100 is a thermal conductive sheet. Since the thermal conductive sheet is freely deformable, it is supported by a support member 44. The interlocking member 28b moves the support member 44 in accordance with the movement of the cover 20, and as a result, the cover 20 and the heat-absorbing member 38 move in conjunction. However, the embodiments of this disclosure are not limited to this. If the heat-absorbing member is not a sheet but a highly rigid member, the interlocking member may directly change the position of the heat-absorbing member based on the state of the cover.

[0076] Furthermore, in the first embodiment described above, as shown in Figures 2A and 6, the interlocking member 28b is provided on the outer cover 28 of the cover 20. However, the embodiments of this disclosure are not limited to this. That is, the interlocking member only needs to change the position of the heat-absorbing member based on the state of the cover. For example, the interlocking member may be a rack and pinion mechanism consisting of a pinion gear provided on the rotating cover and a rack provided on the support member (or heat-absorbing member).

[0077] (Embodiment 6) Furthermore, in the first embodiment described above, the interlocking member 28b is configured to mechanically change the position of the heat-absorbing member 38 based on the state of the cover 20. However, the embodiments of this disclosure are not limited thereto.

[0078] Figure 14 is a schematic cross-sectional view of a portion of the imaging device around the connector according to Embodiment 6.

[0079] As shown in Figure 14, the imaging device according to this embodiment 6 differs from the above-described embodiment 4 in that the position of the heat-absorbing member is changed electrically. Therefore, this embodiment 6 will be described focusing on the differences. Also, components that are substantially the same as those in the above-described embodiment 4 are denoted by the same reference numerals.

[0080] In this sixth embodiment, a lever switch 650 for detecting the rotation of the cover and an actuator 652 for rotating the support member 444 are provided. The actuator 652 is, for example, a motor that rotates the support member 444 via a cam 654. For example, the lever switch 650 detects the sliding movement of the outer cover 128 of the cover 120, that is, it detects the state in which the cover closes the input opening, as shown in Figure 2D. Based on this detection result, the actuator 652 rotates the cam 654, and the rotating cam 654 moves the support member 444 toward the recording medium 100 inserted into the connector 332. As a result, the heat-absorbing member 438 provided on the support member 444 comes into contact with the recording medium 100. In other words, the lever switch 650 and the actuator 652 function as interlocking members that change the position of the heat-absorbing member 438 based on the state of the cover 120.

[0081] In addition, in the first embodiment described above, the heat from the recording medium 100 is transferred to the heat dissipation member 40 provided inside the housing 12 via the heat-absorbing member 38, which is a heat-conducting sheet. However, the embodiments of this disclosure are not limited to this. For example, the heat from the recording medium may be transferred to a cover having an outer surface exposed to the outside via a support member in contact with the cover. For example, in the second embodiment shown in Figure 10, by making the outer cover 128 of the cover 120 out of metal, the heat from the recording medium 100 is transferred to the heat dissipation member 240 and the outer cover 128, respectively, via the heat-absorbing member 238 and the support member 244.

[0082] Furthermore, in the first embodiment described above, the interlocking member 28b is provided on the outer cover 28 of the cover 20. In the first embodiment, the locking member 30 slides in the direction of extension (Z-axis direction) of the rotational centerline CL of the cover 26. By using a power direction conversion means such as a cam, the movement of the locking member 30 and the movement of the free end 244a of the indicator member 244 can be linked in a predetermined direction. With such a structure, even if an interlocking member that moves in conjunction with the movement of the locking member 30 is provided, it is possible to keep the heat-absorbing member in contact with or away from the recording medium.

[0083] In other words, the imaging device according to the embodiment of the present disclosure is, in a broad sense, an imaging device comprising: a housing having an input slot for a card-shaped recording medium including a heat source; a cover for opening and closing the input slot; a connector provided inside the housing into which the recording medium inserted into the input slot is detachably inserted in a first direction; a heat-absorbing member that is movable in a second direction intersecting the first direction with respect to the recording medium in the state of the connector, and that directly contacts the recording medium in the second direction to absorb heat from the recording medium; a heat-dissipating member thermally connected to the heat-absorbing member; and an interlocking member that changes the position of the heat-absorbing member based on the state of the cover, wherein the interlocking member separates the heat-absorbing member from the recording medium when the cover is in the state of the input slot, and keeps the heat-absorbing member in contact with the recording medium when the cover is in the state of the input slot.

[0084] As described above, the embodiments described in this disclosure have been explained as examples of the technology. For this purpose, drawings and a detailed description are provided. Therefore, among the components described in the drawings and detailed description, there may be not only components that are essential for solving the problem, but also components that are not essential for solving the problem, in order to illustrate the technology described above. For this reason, the mere fact that these non-essential components are described in the drawings and detailed description should not be immediately assumed to be essential.

[0085] Furthermore, since the embodiments described above are for illustrative purposes of the technology described herein, various modifications, substitutions, additions, omissions, etc., can be made within the scope of the claims or equivalents thereof.

[0086] For example, the configuration of any one embodiment of the above-described multiple embodiments can be applied to other embodiments. For example, the configuration of Embodiment 3 shown in Figure 10 may be applied to Embodiment 1. That is, as shown in Figure 5, instead of the notch 36b that exposes the recording medium 100 provided in the connector frame 36 of the connector 32, a notch or through hole that exposes the recording medium 100 may be provided in the substrate 34.
