[0004] [Patent Document 1] Japanese Patent Application Publication No. 2017-097014 Summary of the Invention [Problem to be solved by the invention]

[0005] In an installation-type imaging device that is fixed to a wall, ceiling, or the like, a slot for inserting a memory card is mounted on a circuit board.

[0006] When assembling a board with a slot mounted thereon, it is necessary to take into consideration assembly errors, so a gap is formed between the housing and the board. Therefore, even if the slot is mounted on the board as close as possible to the edge of the board, a gap will also be formed between the slot and the housing.

[0007] In this case, when inserting the memory card into the slot, there is a risk of inserting the memory card at an angle and inserting it into the gap between the slot and the housing, or into the gap between the housing and the circuit board. For example, if the memory card is inserted at an angle, it may interfere with the edge of the slot, potentially damaging the slot or the memory card.

[0008] An object of the present invention is to prevent the incorrect insertion of a recording medium into a mounting portion in an imaging device. [Means for solving the problem]

[0009] An imaging device in one embodiment has a first housing, a second housing arranged inside the first housing, an imaging element housed in the first housing and receiving subject light via an optical member, an attachment section to which a recording medium is detachably attached, a board housed within the first housing and on which the attachment section is mounted, and a first guide sheet covering a gap formed between the second housing and the attachment section, the first guide sheet extending into the interior of the attachment section.

[0010] An imaging device in another embodiment includes a first housing, a second housing arranged inside the first housing, an imaging element housed in the first housing and receiving subject light via an optical member, an attachment section to which a recording medium is removably attached, a board housed within the first housing and on which the attachment section is mounted, and a guide sheet covering a gap formed between the second housing and the board, the guide sheet extending into the interior of the attachment section. [Effects of the Invention]

[0011] According to the present invention, it is possible to prevent the recording medium from being erroneously inserted into the mounting portion in the imaging device. [Brief explanation of the drawings]

[0013] Hereinafter, an imaging device according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0014] The imaging device is not particularly limited in its use, but is suitable for installation as a surveillance camera or monitoring camera in hospitals, nursing homes, factories, stores, etc. The imaging device is also switchable between normal imaging mode and night vision mode depending on the brightness of the surrounding external environment. In normal imaging mode, imaging is performed using light incident on an imaging optical system (optical components) when the external environment is bright. In night vision mode, illumination light is emitted when the external environment is dark, and an image of a subject illuminated by the illumination light is captured. The imaging device is also provided with an openable cover that covers a memory slot into which a recording medium is detachably attached. The imaging device is switchable between an open state in which the cover is open and the memory slot is accessible, and a closed state in which the cover is closed and the memory slot is inaccessible. The imaging device is an installation-type imaging device that is fixed to a mounting surface such as a wall or ceiling.

[0015] The imaging device of this embodiment is an installation-type imaging device that is fixed to a mounting surface such as a wall or ceiling, but is not limited to this. That is, the imaging device may be an imaging device that is not fixed to a mounting surface such as a wall or ceiling.

[0016] <Overall Configuration of Imaging Device 10> 1 and 2 are perspective views showing the appearance of an imaging device 10. Fig. 1 shows the imaging device with the cover covering the memory slot in a closed state, and Fig. 2 shows the imaging device with the cover covering the memory slot in an open state.

[0017] The imaging device 10 can be switched from a closed state (FIG. 1) to an open state (FIG. 2). The imaging device 10 can also be switched from an open state (FIG. 2) to a closed state (FIG. 1). As shown in FIG. 1, the imaging device 10 is a stationary imaging device that is used while being fixed to a mounting surface P such as a wall or ceiling with screws or the like. As shown in FIGS. 1 and 2, the imaging device 10 has a camera module 11, a housing (exterior case) 12, an illumination unit 16, a memory slot 26, and a lid 260.

[0018] <Housing 12> The housing (first housing) 12 is composed of a front case 120 and a rear case 121. The front case 120 includes a rectangular or approximately rectangular ceiling plate 122 and side wall plates 123a, 123b, 123c, and 123d connected to each side of the ceiling plate 122. The ceiling plate 122 and the side wall plates 123a, 123b, 123c, and 123d are integrally molded from synthetic resin, with the side wall plate 123a connected to one long side of the ceiling plate 122 and the side wall plate 123b connected to the other long side of the ceiling plate 122. The side wall plate 123c is connected to one short side of the ceiling plate 122, and the side wall plate 123d is connected to the other short side of the ceiling plate 122.

[0019] In the following description, the direction of front case 120 of housing 12 may be referred to as the upward direction, the direction of rear case 121 as the downward direction, the direction of side wall plate 123a as the forward direction, the direction of side wall plate 123b as the backward direction, the direction of side wall plate 123c as the right direction, and the direction of side wall plate 123d as the left direction. The front-to-back direction may be referred to as the first direction, and the up-to-down direction as the second direction. The first direction is a direction intersecting with the optical axis L of lens 111 of camera module 11 (described later), and the second direction is a direction intersecting with the first direction and parallel to the optical axis L.

[0020] As shown in FIGS. 1 and 2 , the ceiling plate 122 of the housing 12 is an exterior plate that intersects with the optical axis L of the lens 111 of the camera module 11. The ceiling plate 122 has an opening 125 and four illumination openings 126. The opening 125 is formed in a circular or approximately circular shape with its center at a position where the optical axis L of the lens 111 passes. The lens 111, which will be described later, is inserted into this opening 125. In this embodiment, the description will be made assuming that the optical axis L of the lens 111 passes through the center of the ceiling plate 122.

[0021] The optical axis L of the lens 111 is not limited to passing through the center of the ceiling board 122. The optical axis L of the lens 111 may pass through a position shifted to the right or left from the center of the ceiling board 122, or may pass through a position shifted to the front or rear from the center of the ceiling board 122.

[0022] The illumination openings 126 are formed at the four corners of the ceiling plate 122. The illumination openings 126 are formed to allow illumination light emitted from an illumination unit 16 (described later) disposed inside the housing 12 to pass to the outside of the imaging device 10. As shown in FIGS. 1 and 2, a total of four illumination openings 126 are provided: two on the right side of the ceiling plate 122 (one on the front side and the other on the rear side) and two on the left side of the ceiling plate 122 (one on the front side and the other on the rear side of the side wall plate). However, the positions of the illumination openings 126 are not limited to the positions shown in the drawings, and are determined appropriately depending on the arrangement positions of the illumination units 16. Furthermore, the number of illumination openings 126 is not limited to four, and may be three or less, five or more, and is determined depending on the number of illumination units 16 provided in the imaging device 10.

[0023] 3 and 4 are external perspective views of the rear case 121. FIG. 3 shows the rear case 121 as viewed from above, and FIG. 4 shows the rear case 121 as viewed from below. The rear case 121 is fixed to the front case 120 and closes the bottom (lower side) of the front case 120. The rear case 121 is fixed to the front case 120 by, for example, screw connection. The rear case 121 has a rectangular or approximately rectangular bottom surface 121a similar to the ceiling panel 122 of the front case 120, and side wall panels 121b, 121c, 121d, and 121e that contact each side of the bottom surface 121a. The bottom surface 121a and the side wall panels 121b, 121c, 121d, and 121e are integrally molded from synthetic resin. Side wall plate 121b is connected to the front side (long side) of bottom surface 121a, and side wall plate 121c is connected to the rear side (long side) of bottom surface 121a. Side wall plate 121d is connected to the right side (short side) of bottom surface 121a, and side wall plate 121e is connected to the left side (short side) of bottom surface 121a. Bottom surface 121a is fixed to the above-mentioned mounting surface P with screws or the like.

[0024] The rear case 121 is also provided with a lid 260 that opens and closes the memory slot 26, into which a recording medium such as a memory card can be detachably attached, so that the memory slot 26 can be accessed from the outside. The lid 260 will be described in detail later. An attachment mechanism 128 for attaching the lid 260 is formed in the rear case 121 near the positions where the memory slot 26 and the lid 260 are located.

[0025] As shown in FIG. 4, the attachment mechanism 128 is a cutout portion formed by cutting out a portion of the bottom surface 121a, which is the first surface of the rear case 121, and a portion of the side wall plate 121b, which is the second surface connected to the bottom surface 121a. When the lid 260 is in the closed state, a portion of the lid 260 is accommodated in the attachment mechanism 128 formed as a cutout portion. A downward-facing wall surface 128a formed on the upper side of the attachment mechanism 128 forms a recessed accommodation portion 128b. A portion of the lid 260, which will be described later, is accommodated in the accommodation portion 128b. An opening 128d is formed on the lower side of the wall surface 128c formed on the rear side of the attachment mechanism 128. Also, as shown in FIG. 3, a protrusion 127 extending upward in the second direction is formed on the bottom surface 121a. The protrusion 127 is formed on the rear side of the opening 128d.

[0026] <Internal configuration of the imaging device 10> Fig. 5 is a cross-sectional view of the imaging device 10 taken along line AA in Fig. 1. The imaging device 10 includes a substrate 17 and a control unit 31 in addition to the above-described configuration.

[0027] <Camera Module 11> The camera module 11 includes an imaging element (image sensor) 110 such as a CMOS or a CCD, and a lens 111. The imaging element 110 is mounted on a substrate 112 and housed in the housing 12. The lens 111 is disposed above the imaging element 110 and held by a lens holder 113. The lens 111 held by the lens holder 113 is disposed at a position where it protrudes upward relative to the ceiling plate 122 through an opening 125 formed in the ceiling plate 122 of the housing 12 described above. The substrate 112 on which the imaging element 110 is mounted is fixed below the lens holder 113 by, for example, screw connection.

[0028] As another embodiment of the camera module 11, the lens 111 may not protrude beyond the ceiling panel 122. In this case, for example, a shutter mechanism for privacy protection may be provided above the lens 111.

[0029] Subject light arriving from outside the imaging device 10 is guided by the lens 111 to the light receiving surface of the imaging element 110 and collected. In other words, the lens 111 is an optical element (imaging optical system) that forms an image of the object to be imaged on the light receiving surface of the imaging element 110, or is at least a part of the optical element. The imaging element 110 converts the brightness of the light in the image formed by the lens 111 into an amount of electric charge, and outputs a signal (image signal) according to the amount of converted electric charge.

[0030] <Lighting Section 16> 1 and 2 emits illumination light that illuminates an object to be imaged when imaging is performed in a dark environment (i.e., when imaging in night vision mode). The illumination unit 16 has an illumination light source such as an LED, and is controlled by a control unit 31 (described later) to emit light having a wavelength in the infrared range (infrared light). Note that the illumination unit 16 is not limited to emitting infrared light as illumination light, and may emit visible light other than infrared light as illumination light.

[0031] The imaging device 10 is equipped with four lighting units 16. Of the four, one pair of lighting units 16 is provided on the right side of the ceiling board 122, with one lighting unit 16 on the front side and the other lighting unit 16 on the rear side. The other pair of lighting units 16 is provided on the left side of the ceiling board 122, with one lighting unit 16 on the front side and the other lighting unit 16 on the rear side.

[0032] The number of illumination units 16 provided in the imaging device 10 is not limited to four. The imaging device 10 may be provided with three or fewer illumination units 16, or may be provided with five or more illumination units 16.

[0033] <Board 17> 5, the board 17 is provided on the lower side inside the housing 12 and is attached to the bottom surface 121a by, for example, screws. An antenna (not shown) that interconnects with other devices via, for example, wireless LAN (Wi-Fi) is mounted on the board 17. This allows the imaging device 10 to wirelessly transmit a signal (image signal) output from the imaging element 110 to other devices such as smartphones and tablet terminals. The imaging device 10 can also be remotely controlled by other devices such as smartphones.

[0034] A plate-shaped shield member 17a is provided on the underside of the substrate 17. As shown in Fig. 6 described below, a space S having a predetermined gap in the vertical direction is formed between the shield member 17a and the bottom surface 121a. This space S is a space into which the insertion portion 263 of the lid 260 can be inserted.

[0035] <Control unit 31> 5 is mounted on a substrate 310. The control unit 31 is configured with, for example, a CPU, a memory, etc., and is electrically connected to a substrate 112 on which the image sensor 110 is mounted. The control unit 31 is a processor that controls each part of the image capturing device 10 by reading and executing a control program pre-recorded in a recording medium such as a flash memory. For example, the control unit 31 controls the power supply to each part such as the image sensor 110 by a power supply unit.

[0036] <Inner housing 13> Fig. 6 is a cross-sectional view of the imaging device 10 taken along line BB in Fig. 1, and Fig. 7 is a cross-sectional view of the imaging device 10 taken along line CC in Fig. 2. An inner housing (second housing) 13 is arranged inside the housing (first housing) 12. The inner housing 13 is made up of an inner front case 14 and an inner rear case 15. A board 19 is provided inside the inner front case 14. A capacitor 18 is mounted on the board 19. In other words, the inner front case 14 is arranged so as to cover the board 19 and the capacitor 18, and the inner front case 14 is further covered by a front case 120.

[0037] <Memory slot 26> The memory slot 26 is an attachment portion into which a predetermined recording medium is detachably attached. One example of the recording medium is an SD memory card 20. More specifically, the imaging device 10 has a slot portion into which the SD memory card 20 can be inserted and removed.

[0038] The memory slot (slot portion) 26 is mounted on the substrate 17. When a cover 260 provided on the rear case 121 is opened, the SD memory card 20 can be inserted into and removed from the memory slot 26.

[0039] The SD memory card 20 is inserted into and removed from the memory slot 26 through an opening between the inner front case 14 and the inner rear case 15 .

[0040] <Lid 260> Fig. 6 is a cross-sectional view of imaging device 10 with lid 260 in a closed state, and Fig. 7 is a cross-sectional view of imaging device 10 with lid 260 in an open state. Lid 260 has a wall surface 261, a bottom surface 262, and an insertion portion 263. Wall surface 261, bottom surface 262, and insertion portion 263 are integrally molded from an elastic material such as elastomer.

[0041] Wall surface 261 is a surface that is parallel or approximately parallel to side wall plate 121b of rear case 121 when lid 260 is in the closed state, i.e., a surface that intersects with the front-to-rear direction. Wall surface 261 is formed with engagement portion 264 that is received in and engages with accommodation portion 128b formed in mounting mechanism 128 of rear case 121 when lid 260 is in the closed state. Engagement portion 264 is provided on the upper side surface of wall surface 261 and is a protrusion that protrudes upward in the second direction. In addition, a recess 261a is formed near the upper end of wall surface 261. When lid 260 is in the closed state, a user can open lid 260 by hooking a fingernail or the like into recess 261a.

[0042] The bottom surface portion 262 is connected to the lower end of the wall surface 261. The bottom surface portion 262 is a surface that is parallel or approximately parallel to the bottom surface 121a of the rear case 121 in the closed state. In other words, in the closed state, the lower surface of the bottom surface portion 262 faces the placement surface P to which the imaging device 10 is fixed. An insertion portion 263 is provided on the rear side of the bottom surface portion 262, i.e., on the end on the side that is not connected to the wall surface 261.

[0043] The insertion portion 263 is formed in a plate shape extending in the front-rear direction. That is, the insertion portion 263 extends in a first direction, which is the movement direction when the lid 260 moves, as described below. The insertion portion 263 is inserted into the rear case 121 through an opening 128d (see FIG. 4) of the attachment mechanism 128 formed in the rear case 121. The inserted insertion portion 263 is located in the space S in the up-down direction between the bottom surface 121a of the rear case 121 and the board 17 when in the closed state.

[0044] When opening the lid 260, the lid 260 slides forward and backward to switch between an open and closed state. In the closed state shown in FIG. 6, the user hooks a fingernail or the like into the recess 261a of the lid 260 and moves the lid 260 downward. This disengages the engagement between the engagement portion 264, which is a protrusion formed on the upper end of the wall surface 261, and the accommodation portion 128b of the attachment mechanism 128. This causes the lid 260 to move (slide) forward along the first direction and enter the open state.

[0045] <Guide Sheet 40> Fig. 8 is a partially enlarged cross-sectional view showing the structure around the slot portion, Fig. 9 is a perspective view showing the structure of the guide sheet, Fig. 10 is a partially enlarged perspective view showing the attachment structure of the guide sheet, and Fig. 11 is a partially enlarged perspective view of the attachment structure of the guide sheet as seen from inside the case. The imaging device 10 is provided with a guide sheet (first guide sheet) 40 that covers the gap 30 formed between the inner front case 14 and the memory slot 26.

[0046] 8 and 9, when assembling the board 17 on which the memory slot 26 is mounted, it is necessary to take into consideration assembly errors, and therefore a gap 70 is formed between the inner rear case 15 and the board 17. Therefore, even if the memory slot 26 is mounted on the board 17 as close to the edge of the board as possible, a gap 30 is also formed between the memory slot 26 and the inner front case (second housing) 14. If a gap 30 is formed between the card insertion side end of the memory slot 26 and the inner front case 14, there is a risk that the SD memory card 20 will be inserted at an angle into the memory slot 26 by mistake, and the SD memory card 20 will be inserted into the gap 30. Furthermore, if the SD memory card 20 is inserted at an angle, the SD memory card 20 may interfere with the edge 26c of the memory slot 26 on the card insertion side, which may result in damage to the memory slot 26 or the SD memory card 20.

[0047] Therefore, the imaging device 10 of this embodiment is provided with a guide sheet 40 arranged to cover the gap 30, and the guide sheet 40 extends into the memory slot 26. The guide sheet 40 is a foldable, thin, sheet-like member, and is preferably formed from an insulating material such as resin. One end 40a of the guide sheet 40 is arranged along the inner front case 14, and is folded inward at a bending portion 40e along the edge of the inner front case 14 at a substantially right angle. Furthermore, the other end 40b of the guide sheet 40 extends into the memory slot 26. In other words, the other end 40b of the guide sheet 40 is inserted into the memory slot 26.

[0048] Specifically, one end 40a of the guide sheet 40 extending from the inner front case 14 to the inside of the memory slot 26 is fixed to the inner front case 14, and the other end 40b of the guide sheet 40, which is turned approximately at a right angle to the one end 40a at the bending portion 40e, is inserted into the inside of the memory slot 26 and positioned along the inner wall 26a.

[0049] As a result, the gap 30 between the card insertion end of the memory slot 26 and the inner front case 14 is covered by the guide sheet 40. In other words, the gap 30 can be blocked by the guide sheet 40. Furthermore, a portion of the edge 26c of the memory slot 26 is covered by the guide sheet 40.

[0050] The guide sheet 40 is fixed by, for example, adhering one end 40a of the guide sheet 40 to the inner front case 14 with an adhesive or the like. The other end 40b may or may not be fixed to the inner wall 26a of the memory slot 26. If the end 40b is fixed, it is fixed to the inner wall 26a with, for example, an adhesive. One example of the adhesive is double-sided tape 50, and the guide sheet 40 is attached with the double-sided tape 50. In this embodiment, a case where the adhesive is double-sided tape 50 will be described, but the adhesive is not limited to double-sided tape 50.

[0051] Furthermore, as shown in FIG. 9 , the guide sheet 40 has protruding portions 40c and 40d that protrude in the width direction Q of the guide sheet 40. Specifically, the protruding portions 40c and 40d protrude toward the right side of the width direction Q of the guide sheet 40, and similarly, the protruding portions 40c and 40d protrude toward the left side. That is, two protruding portions 40c and two protruding portions 40d are provided so as to protrude to the left and right, respectively, in the width direction Q of the guide sheet 40. The two protruding portions 40c protruding to the left and right sides are formed on the same surface as one end portion 40a of the guide sheet 40, and the two protruding portions 40d protruding to the left and right sides are formed on the same surface as the other end portion 40b of the guide sheet 40, whose direction is changed at approximately a right angle to one end portion 40a at the bent portion 40e.

[0052] 10 and 11, these protrusions 40c, 40d are hooked onto wall portions 128f, 128g on the back side of recess 128e of attachment mechanism 128 of rear case 121. In detail, in attachment mechanism 128, recess 128e is made up of wall surface 128a and wall surface 128c, and recess 128e is disposed between protrusions 40c and 40d on both the left and right sides of guide sheet 40. As a result, protrusion 40c of guide sheet 40 is hooked onto wall portion 128f on the back side of wall surface 128a, and protrusion 40d is hooked onto wall portion 128g on the back side of wall surface 128c.

[0053] The guide sheet 40 preferably has elasticity and is preferably made of an insulating material.

[0054] <Operation of the embodiment> In the imaging device 10, the gap 30 between the card insertion end of the memory slot 26 and the inner front case 14 is covered by a guide sheet 40. An end 40b of the guide sheet 40 is inserted into the memory slot 26. This provides a guide for the SD memory card 20 when it is inserted into the memory slot 26. As a result, the SD memory card 20 can be reliably guided into the memory slot 26, and erroneous insertion of the SD memory card 20 into the memory slot 26 can be prevented.

[0055] Furthermore, because the guide sheet 40 covers one edge 26c of the memory slot 26 on the card insertion side, the SD memory card 20 is inserted at an angle when inserted into the memory slot 26, preventing the SD memory card 20 from interfering with the edge 26c of the memory slot 26. This prevents damage to the memory slot 26 or the SD memory card 20.

[0056] The guide sheet 40 also has protrusions 40c and 40d that protrude in the width direction Q, and these protrusions 40c and 40d are hooked onto wall portions 128f and 128g, respectively, on the rear side of the recess 128e of the attachment mechanism 128 of the rear case 121. This prevents the protrusions 40c and 40d from coming off the rear case 121, and the guide sheet 40 from falling off the rear case 121. In other words, the guide sheet 40 is stably held by the rear case 121. At this time, the guide sheet 40 is hooked onto the rear case 121 at two or more points, and is therefore held by the rear case 121 with even greater stability.

[0057] Furthermore, one end 40a of the guide sheet 40 is attached to the inner front case 14 with double-sided tape 50, so that the one end 40a of the guide sheet 40 is fixed to the inner front case 14 with the other end 40b of the guide sheet 40 inserted into the memory slot 26. This allows the SD memory card 20 to be inserted stably into the memory slot.

[0058] Furthermore, the end 40a of the guide sheet 40 is attached to the inner front case 14 with double-sided tape 50, which increases the fixing strength of the guide sheet 40 to the inner front case 14. This makes it possible to prevent the guide sheet 40 from coming off when the SD memory card 20 is removed from the memory slot 26.

[0059] However, the guide sheet 40 does not have to be attached to the inner front case 14 with the double-sided tape 50. Since the guide sheet 40 is not fixed to the inner front case 14, when assembling the imaging device 10, it is sufficient to simply hook the guide sheet 40 into the recess 128e of the attachment mechanism 128 of the rear case 121, thereby improving the ease of assembly of the imaging device 10.

[0060] Furthermore, since no member for fixing the guide sheet 40 is required when assembling the imaging device 10, the number of parts of the imaging device 10 can be reduced, and the assembly cost of the imaging device 10 can be kept down.

[0061] Furthermore, because the guide sheet 40 is elastic, it can be inserted into the memory slot 26 while being deformed. This improves the ease of assembly of the imaging device 10. Furthermore, if the guide sheet 40 is tilted inward within the memory slot 26 when the SD memory card 20 is inserted into the memory slot 26, the elasticity of the guide sheet 40 can reduce play between the SD memory card 20 and the inner wall of the slot. At this time, a pressing force is applied to the SD memory card 20 due to the elasticity of the guide sheet 40, thereby improving the resistance of the SD memory card 20 to poor contact caused by vibration or impact.

[0062] Furthermore, by forming the guide sheet 40 from an insulating material, it is possible to prevent electrical problems such as short circuits with the terminals of the SD memory card 20.

[0063] Furthermore, it is preferable that the color of guide sheet 40 is the same as the color of the exterior cases such as front case 120 and rear case 121. In this case, it is possible to improve the design of imaging device 10. However, the color of guide sheet 40 may be a different color from the color of the exterior cases.

[0064] <First Modification> Fig. 12 is a partially enlarged cross-sectional view showing the structure around the slot portion of the first modified example. In the first modified example shown in Fig. 12, in addition to the guide sheet (first guide sheet) 40, another guide sheet (second guide sheet) 60 is arranged in a position opposite the guide sheet 40. In this structure, the guide sheet 60 covers the gap 70 formed between the inner rear case 15 and the board 17, and also covers part of the edge 26c of the card insertion opening 26b of the memory slot 26.

[0065] One end 60a of the guide sheet 60 is disposed inside the memory slot 26, while the other end 60b of the guide sheet 60 is disposed along the outer surface of the shield plate 32 provided on the substrate 17. In this case, the end 60b of the guide sheet 60 may or may not be fixed to the shield plate 32 with an adhesive such as double-sided tape 50. The guide sheet 60 has bent portions 60c and 60d bent along the edge of the inner rear case 15 between the one end 60a and the other end 60b.

[0066] That is, the guide sheet 60 covers the gap 70 and also covers part of the edge 26c of the card insertion opening 26b of the memory slot 26, and furthermore, one end 60a of the guide sheet 60 extends into the interior of the memory slot 26. This provides a guide for the SD memory card 20 when it is inserted into the memory slot 26. As a result, the SD memory card 20 can be reliably guided into the memory slot 26, and erroneous insertion of the SD memory card 20 into the memory slot 26 can be prevented.

[0067] Furthermore, by providing guide sheet 60 in addition to guide sheet 40, edge 26c of memory slot 26 on the card insertion side is covered by guide sheet 40 and guide sheet 60, which prevents the SD memory card 20 from interfering with edge 26c of memory slot 26 when a card is inserted into memory slot 26. As a result, damage to memory slot 26 and SD memory card 20 can be prevented.

[0068] <Second Modification> Fig. 13 is a partially enlarged cross-sectional view showing the structure around the slot portion of the second modified example. The second modified example shown in Fig. 13 has a structure in which only a guide sheet 60 is provided. That is, only the guide sheet 60 is provided, which covers the gap 70 formed between the inner rear case 15 and the board 17 and also covers part of the edge 26c of the card insertion opening 26b of the memory slot 26, and one end 60a of this guide sheet 60 extends into the interior of the memory slot 26.

[0069] This makes it possible to form a guide when inserting the SD memory card 20 into the memory slot 26. As a result, the SD memory card 20 can be reliably guided into the memory slot 26, and erroneous insertion of the SD memory card 20 into the memory slot 26 can be prevented.

[0070] Furthermore, because the guide sheet 60 covers part of the edge 26c of the memory slot 26 on the card insertion side, it is possible to prevent the SD memory card 20 from interfering with the edge 26c of the memory slot 26 when inserting a card into the memory slot 26. As a result, it is possible to prevent damage to the memory slot 26 and the SD memory card 20.

[0071] Although various embodiments and modifications have been described above, the present invention is not limited to these. Other embodiments conceivable within the scope of the technical concept of the present invention are also included within the scope of the present invention. For example, the guide sheet 40 may be provided not only above or below the memory slot 26, but also on the right or left side of the memory slot 26.
