[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1(a) and 1(b), an electronic magnifier (electronic device) 10 according to this embodiment includes a housing (device body) 20 and a battery cover (cover) 30 that can be attached to and detached from the housing 20. The housing 20 includes a magnifier unit 22, a handle 24, and a neck 26. The magnifier unit 22 has a vertically elongated rectangular frame shape, and is provided with a camera 22a on one side for capturing an image of a subject, and a monitor 22b on the other side for displaying an enlarged image of the subject captured by the camera 22a. The handle 24 is columnar and is the part that is held by a user when using the electronic magnifier 10. A power button 24a is provided on one side of the handle 24. Furthermore, a connector unit 24b having a power connector 24b1 is provided on one end of the handle 24. The neck portion 26 is slightly narrower than the grip portion 24 and connects the magnifying glass portion 22 and the grip portion 24 together.

[0011] In the following description, the arrangement direction of the loupe unit 22 and the grip unit 24 is defined as the up-down direction (second direction) of the electronic loupe 10, with the loupe unit 22 on the upper side, and the arrangement direction of the camera 22a and the monitor 22b is defined as the front-to-back direction (first direction) of the electronic loupe 10, with the monitor 22b side of the loupe unit 22 on the front side, and the left-to-right direction when the electronic loupe 10 is viewed from the front with the loupe unit 22 on the upper side is defined as the left-to-right direction of the electronic loupe 10. As shown in FIG. 5, a battery housing 54a that houses multiple batteries B is provided on the rear side of the grip unit 24 (rear grip unit 54 described below). The battery cover 30 is attached to the housing 20 to cover the opening of the battery housing 54a, and is removed from the housing 20 by sliding it in a direction from the grip unit 24 toward the loupe unit 22 (removal direction), i.e., upward.

[0012] 1 and 5, the housing 20 is composed of a front case 40 provided in front of the electronic magnifier 10, a grip case 44 provided in front of the grip 24, and a rear case 50 provided in the rear of the electronic magnifier 10. As shown in FIG. 7, the front case 40 has a portion corresponding to the front portion of the magnifier 22 (hereinafter referred to as the "front frame portion 42"), a portion corresponding to the front portion of the neck 26 (hereinafter referred to as the "front neck portion 46"), and an inner wall portion 48 extending downward from the front neck portion 46 and disposed inside the grip 24. On the other hand, as shown in FIG. 5, the rear case 50 has a portion corresponding to the rear portion of the magnifier 22 (hereinafter referred to as the "rear frame portion 52"), a portion corresponding to the rear portion of the grip 24 (hereinafter referred to as the "rear grip portion 54"), and a portion corresponding to the rear portion of the neck 26 (hereinafter referred to as the "rear neck portion 56").

[0013] As shown in FIG. 7, the front frame 42 has an opening 42a into which the monitor 22b is fitted. The grip case 44 is generally box-shaped and opens rearward. The inner wall 48 is housed in approximately the upper half of the interior of the grip case 44. The inner wall 48 has a plate-shaped bottom plate 48a and wall-like portions 48b that rise rearward from both the left and right sides of the bottom plate 48a. A protrusion 48c that protrudes rearward is provided on a portion of the tip surface 48b1, which is the rising tip of each of the wall-like portions 48b. The configuration of the protrusion 48c will be described in detail later. The front neck 46 connects the front frame 42 and the inner wall 48.

[0014] As shown in FIG. 5, the rear grip portion 54 has six first through-holes 54b penetrating the left and right surfaces, which are the opening end faces of the battery housing portion 54a, in the front-rear direction. Each first through-hole 54b has a vertically elongated rectangular opening, and three first through-holes 54b are provided on each side, arranged in pairs in the left-right direction. The opening of each first through-hole 54b is large enough to allow a first hook (engaged portion) 32 of the battery cover 30, which will be described later, to pass through. The inner surface near each first through-hole 54b on the left and right sides (more specifically, below the first through-hole 54b) forms an engaging portion 54b1 that engages with the first hook 32 inserted through the first through-hole 54b (see FIG. 3). That is, the housing 20 has six engaging portions 54b1. A second through-hole 54c is provided in a position near the rear of the side surface at the lower end of the battery housing portion 54a, penetrating the side surface in the up-down direction. The second through-hole 54c has a rectangular opening that is long on both sides and is sized to allow a second hook 34 of the battery cover 30, which will be described later, to be inserted therethrough.

[0015] The front case 40 and the rear case 50 configured as described above are assembled by overlapping the front frame portion 42 and the rear frame portion 52, the front neck portion 46 and the rear neck portion 56, the inner wall portion 48 and the rear grip portion 54 in the front-to-rear direction and fastening them with screws or the like. The grip portion case 44 is then assembled to the outside of the inner wall portion 48 to form the housing 20. Here, in the front case 40, the front frame portion 42, the front neck portion 46 and the inner wall portion 48 are integrally formed, and in the rear case 50, the rear frame portion 52, the rear neck portion 56 and the rear grip portion 54 are integrally formed. Therefore, even if the housing 20 receives an external impact or the like, the neck portion 26, which is narrower than the other portions, is less likely to break (break), and the strength of the housing 20 is ensured.

[0016] Next, the structure of the battery cover 30 will be described. As shown in FIGS. 6 and 2(b), the battery cover 30 has a generally rectangular plate shape that is vertically elongated when viewed from the rear. The battery cover 30 bulges outward (toward the rear) in a generally convex arc shape from both left and right edges 30F when viewed from the top-bottom direction. The portion of the battery cover 30 that overlaps with the neck portion 26 of the housing 20 when attached to the housing 20 is a narrow portion 30W that is slightly narrower in width than the neck portion 26. Six first hooks 32 that protrude forward in a hook-like shape are provided on both left and right edges 30F of the battery cover 30. The first hooks 32 are arranged in pairs in the left-right direction, with three hooks provided on each edge 30F. Specifically, one pair of first hooks 32 is provided on the upper end 30U side of the inner surface 30I of the battery cover 30, one pair is provided on the lower end 30L side, and one pair is provided in the approximate center in the up-down direction. Each first hook 32 is provided at a position overlapping (corresponding to) each first through-hole 54b of the rear grip portion 54 when the battery housing portion 54a is covered with the battery lid 30. The configuration of the first hooks 32 will be described in detail later.

[0017] As shown in FIG. 6 , the lower end 30L of the battery cover 30 is provided with a second hook 34 that protrudes downward in a hook-like shape. The tip of the second hook 34 is slightly bent rearward so that the tip engages with the rear grip portion 54 when inserted into the second through-hole 54c of the rear frame portion 52. When the tip of the second hook 34 is engaged with the rear grip portion 54, pressing the pressing portion 30P (see FIG. 2 ) on the lower end 30L of the battery cover 30 from the outer surface 30O bends the second hook 34 forward, disengaging the second hook 34 from the rear grip portion 54. After disengaging the second hook 34 from the rear grip portion 54, the battery cover 30 attached to the housing 20 can be slid upward to move slightly rearward, as described below, and removed from the housing 20. The inner surface 30I of the battery cover 30 is provided with a plurality of ribs 36 in a generally lattice shape to improve the strength of the battery cover 30.

[0018] Additionally, a substantially plate-shaped inner plate 60 is attached to the inner surface 30I of the battery lid 30. The inner plate 60 is shaped and sized to cover the opening on the inner surface 30I side of the battery lid 30. The inner plate 60 has two substantially rectangular openings 60a. A cushion member C is housed in each opening 60a. Each cushion member C is attached to the rib 36 on the inner surface 30I side of the battery lid 30 by adhesive or the like. The front surface of each cushion member C is exposed forward of the inner plate 60, and presses against the rear side of each battery B housed in the battery housing portion 54a when the battery lid 30 is attached to the housing 20. Therefore, when the battery lid 30 is attached to the housing 20, the battery lid 30 is biased rearward by the reaction force that each cushion member C receives from each battery B.

[0019] Next, the protrusions 48c provided on the inner wall 48 of the housing 20 will be described in detail with reference to Fig. 7. The protrusions 48c are provided as a pair to correspond to a pair of engagement portions 54b1 (a pair of first through holes 54b) of the housing 20 that are provided in approximately the center in the up-down direction of the rear grip portion 54, among the engagement portions 54b1 (each of the first through holes 54b of the housing 20). The pair of protrusions 48c are provided at positions that overlap the pair of first through holes 54b in the front-rear direction (see Fig. 3). The pair of protrusions 48c also correspond to a pair of first hooks 32 that are provided in approximately the center in the up-down direction of the first hooks 32 (hereinafter referred to as "first hooks 32 in the approximately center") As shown in enlarged view E2 of Fig. 7, the pair of protrusions 48c have a flat surface 48c2 that is a protruding tip surface that protrudes rearward and is flat in the up-down and left-right directions, and an inclined surface 48c1 that slopes downward and forward from the flat surface 48c2 to the tip surface 48b1. Note that, as shown in Fig. 3, the protrusions 48c and the engaging portion 54b1 are provided on the same plane that is in the front-rear and up-down directions.

[0020] Next, the configuration of the first hooks 32 provided on the battery cover 30 will be described in detail with reference to FIG. 6. As shown in the enlarged view E1 of FIG. 6, each first hook 32 has a rising portion 32a rising forward from the edge 30F on both the left and right sides of the battery cover 30, and a bent portion 32b bent downward at a substantially right angle from the tip of the rising portion 32a. The outer surface (front surface) of the bent portion 32b (hereinafter referred to as the "bent outer surface 32b1") and the inner surface (rear surface) of the bent portion 32b (hereinafter referred to as the "bent inner surface (second engaged portion) 32b2") are flat in the up-down and left-right directions. The cross section of the lower end (hereinafter referred to as the "bent lower end 32b3"), which is the tip of the bent portion 32b, is substantially triangular with a tapered tip. In addition, a corner (first engaged portion) 32b4, which is the boundary between the rising portion 32a and the bent portion 32b, is rounded. The corner portion 32b4 and the bent inner surface 32b2 are located on opposite sides of the first hook 32.

[0021] Next, the manner in which the battery cover 30 is attached to and detached from the housing 20 will be described. When attaching the battery cover 30 to the housing 20, first, the first hooks 32 of the battery cover 30 are aligned with the first through-holes 54b of the housing 20, and the first hooks 32 are inserted into the first through-holes 54b. Then, the cushion members C come into contact with the batteries B, preventing the battery cover 30 from moving forward any further. In this state, the first hooks 32 located approximately in the center are slightly spaced apart from the protrusions 48c (see FIG. 3(b)). Then, when the battery cover 30 is slid downward from this state, the curved inner surfaces 32b2 of the first hooks 32 engage with the lower inner surfaces of the first through-holes 54b, i.e., the engaging portions 54b1, and the first hooks 32 engage with the housing 20 in the front-to-rear direction. At this time, since the cross section of the bent lower end portion 32b3 of each first hook 32 is tapered, it is easy for the first hook 32 to slip into the front side of the corresponding engaging portion 54b1.

[0022] Furthermore, by sliding the battery cover 30 downward until the bottom end 30L abuts or approaches the connector portion 24b, the second hook 34 of the battery cover 30 is inserted into the second through-hole 54c, and the second hook 34 bends and engages with the rear grip portion 54. Through the above procedure, the battery cover 30 is attached to the housing 20. In this state, as shown in FIG. 3(a), the curved inner surfaces 32b2 of the first hooks 32 are in contact with the corresponding engagement portions 54b1, and the battery cover 30 is biased rearward by the reaction force that each cushion member C receives from each battery B, as described above. This makes it difficult for the battery cover 30 to come off the housing 20 and reduces rattling of the battery cover 30. At this time, each cushion member C is crushed, and its thickness in the front-to-rear direction is smaller than that in the state shown in FIG. 3(b). Meanwhile, in this state, the first hook 32 is spaced apart from the protrusion 48c, and the bent outer surface 32b1 of the first hook 32 in the approximate center is spaced apart from the tip surface 48b1 of the inner wall portion 48. In addition, the bent outer surface 32b1 overlaps with the protrusion 48c in the up-down direction.

[0023] When removing the battery cover 30 from the housing 20, first, by pressing the pressing portion 30P of the battery cover 30, the second hook 34 is disengaged from the rear grip portion 54, and the battery cover 30 is slid upward. Then, the engagement between each first hook 32 and each engagement portion 54b1 is disengaged, and the corner portion 32b4 of the first hook 32 in the approximate center comes into contact with the inclined surface 48c1 of the protrusion 48c (see FIG. 4(a)), rides up on the inclined surface 48c1, and slides upward and rearward along the inclined surface 48c1 as the battery cover 30 slides. Therefore, the battery cover 30 is pushed rearward by the inclined surface 48c1 as it slides, and moves rearward.

[0024] Then, by sliding the battery cover 30 further rearward (upward), the bent outer surface 32b1 of the first hook 32 located approximately in the center rides up onto the flat surface 48c2, which is the tip surface of the protrusion 48c (see FIG. 4(b)). In this state, as shown in FIG. 4(b), the battery cover 30 is slightly spaced from the rear grip portion 54, creating a gap between them. This allows, for example, a user to hook their finger on the battery cover 30 through the gap on the upper end 30U side of the battery cover 30, making it easy to remove the battery cover 30 from the housing 20. Note that when each first hook 32 is removed from each first through-hole 54b, because the tip of the bent portion 32b of each first hook 32 has a substantially triangular cross section, each first hook 32 can be removed more easily from each first through-hole 54b than, for example, when the tip has a substantially rectangular cross section.

[0025] As described above, the battery cover 30 attachment / detachment structure according to this embodiment includes a housing 20 and a battery cover 30 having a first hook 32 that engages with the housing 20 and is detachable from the housing 20. The housing 20 has an engagement portion 54b1 that engages with the first hook 32 in the front-rear direction and a protrusion 48c that protrudes in the front-rear direction. The first hook 32 rides on the protrusion 48c when slid vertically. With this configuration, in the battery cover 30 attachment / detachment structure according to this embodiment, the battery cover 30 slides and the first hook 32 rides on the protrusion 48c, moving the battery cover 30 in the front-rear direction. This creates a gap between the housing 20 and the battery cover 30, allowing the battery cover 30 to be easily removed from the housing 20. As a result, the degree of freedom in the shape of the battery cover 30 can be increased, and the degree of freedom in the design of the battery cover 30 can be increased.

[0026] In addition, in the detachable structure of the battery cover 30 of this embodiment, the protrusion 48c and the engagement portion 54b1 are provided on the same plane along the front-to-rear and up-down directions, so that when the battery cover 30 is slid up and down, the first hook 32 comes into contact with and rides up on the protrusion 48c, providing a specific configuration for moving the battery cover 30 in the front-to-back direction.

[0027] Furthermore, in the detachable structure of the battery cover 30 of this embodiment, the battery cover 30 has a plurality of first hooks 32, the housing 20 has a plurality of engagement portions 54b1 corresponding to the plurality of first hooks 32, and the protrusion 48c is provided to correspond to some of the engagement portions 54b1. For example, if the protrusion 48c is provided at a position corresponding to the first hook 32 near the end of the battery cover 30 in the sliding direction (up and down direction), the first hook 32 rides up on the protrusion 48c, applying a force in the front-to-back direction near the end of the battery cover 30, and a large force is required to slide the battery cover 30. In contrast, if the protrusion 48c is provided at a position corresponding to the first hook 32 approximately in the center of the battery cover 30 in the sliding direction as in this embodiment, no force in the front-to-back direction is applied near the end of the battery cover 30 when the battery cover 30 slides, making it easier to slide the battery cover 30.

[0028] Furthermore, in the detachable structure of the battery cover 30 of this embodiment, the first hook 32 has a corner 32b4 that contacts the protrusion 48c, and a curved inner surface 32b2 that is provided on the opposite side of the corner 32b4 and engages with the engaging portion 54b1. This makes it possible to provide a specific configuration of the first hook 32 that allows a portion of the first hook 32 to engage with the engaging portion 54b1 and another portion to ride over the protrusion 48c.

[0029] Furthermore, in the attachment / detachment structure of the battery cover 30 of this embodiment, the protrusion 48c has an inclined surface 48c1 that contacts the corner 32b4 and is inclined in the front-to-rear direction across the vertical direction. This provides a specific configuration for moving the battery cover 30 in the front-to-rear direction by having the first hook 32 ride on the protrusion 48c and sliding the battery cover 30 in the vertical direction. Note that in this embodiment, because the corner 32b4 has a rounded corner, the corner 32b4 can slide smoothly on the inclined surface 48c1 compared to when the corner 32b4 has an angular shape, allowing the battery cover 30 to slide more smoothly.

[0030] Furthermore, in the detachable structure of the battery cover 30 of this embodiment, the protrusion 48c moves away from the first hook 32 when the battery cover 30 is attached to the housing 20. With this configuration, the first hook 32 does not interfere with the protrusion 48c when the battery cover 30 is attached to the housing 20, making it easier to slide the battery cover 30.

[0031] Furthermore, in the detachable structure of the battery cover 30 of this embodiment, a portion of the protrusion 48c overlaps with the first hook 32 in the vertical direction when the battery cover 30 is attached to the housing 20. This provides a specific configuration for causing the first hook 32 to interfere with and ride up on the protrusion 48c by sliding the battery cover 30 in the vertical direction from the state in which the battery cover 30 is attached to the housing 20.

[0032] Furthermore, in the detachable structure of the battery cover 30 of this embodiment, the housing 20 has a power connector 24b1 at the lower end of the grip portion 24. By providing the power connector 24b1 at the lower end of the grip portion 24 in this manner, the battery cover 30 slides upward and does not protrude from the housing 20 when slid. However, in this embodiment, the first hook 32 rides up onto the protrusion 48c when the battery cover 30 is slid, so the battery cover 30 can be easily detached from the housing 20. This increases the degree of freedom in the configuration of the housing 20.

[0033] In addition, in the detachable structure of the battery lid 30 of this embodiment, the battery lid 30 is a lid that covers the battery housing section 54a. This configuration increases the degree of freedom in the configuration of the part of the housing 20 where the battery housing section 54a is provided, while realizing a configuration that allows the battery lid 30 to be easily detached from the housing 20.

[0034] The electronic magnifier 10 according to this embodiment comprises a housing 20 as the device body, and a battery cover 30 that has a first hook 32 that engages with the housing 20 and is detachable from a battery housing section 54a of the housing 20. The housing 20 has an engaging section 54b1 that engages with the first hook 32 in the front-to-rear direction and a protrusion 48c that protrudes in the front-to-rear direction, and the first hook 32 rides on the protrusion 48c when slid up and down. This configuration makes it possible to provide an electronic magnifier 10 in which the battery cover 30 that covers the battery housing section 54a can be easily removed.

[0035] Furthermore, in the electronic magnifier 10 of this embodiment, the housing 20 includes a magnifier section 22 and a grip section 24 arranged side by side in the vertical direction, the battery storage section 54a is provided in the grip section 24, and the first hook 32 rides up onto the protrusion 48c when slid from the grip section 24 toward the magnifier section 22. With this configuration, for example, a power connector 24b1 can be provided on the end of the grip section 24 opposite the direction in which the battery cover 30 having the first hook 32 slides. This makes it possible to realize a configuration that allows for easy removal of the battery cover 30 from the grip section 24 while increasing the degree of freedom in the configuration of the grip section 24.

[0036] The above-described embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments may be embodied in various other forms, and various omissions, substitutions, and modifications may be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the inventions and their equivalents as set forth in the claims.
