In the following description of one embodiment, other embodiments that can be applied to the one embodiment will also be described as appropriate. The present disclosure is not limited to the one embodiment below, and different embodiments can be combined with each other, or modified as desired without significantly impairing the effects of the present disclosure. In addition, the same symbols will be used for the same components, and duplicate descriptions will be omitted. Furthermore, components having the same functions will be given the same names. The contents shown are merely schematic, and for the sake of illustration, changes may be made from the actual configuration without significantly impairing the effects of the present disclosure, and some components may be omitted or modified between drawings.

図1は、本実施形態のカメラユニット100の分解斜視図である。レンズ側ベース4からカメラ1とレンズキャップ3を外した状態を示している。カメラユニット100は、例えば図5に示すように、冷蔵庫の最上段の貯蔵室200の天面外側に取付けられて、カメラ1が貯蔵室の前方開口よりも前方(冷蔵庫扉の開き方向側)に配される。 Figure 1 is an exploded perspective view of the camera unit 100 of this embodiment. It shows the state in which the camera 1 and lens cap 3 have been removed from the lens side base 4. The camera unit 100 is attached to the outside of the top surface of the uppermost storage compartment 200 of a refrigerator, for example as shown in Figure 5, with the camera 1 positioned forward of the front opening of the storage compartment (the side in the direction in which the refrigerator door opens).

カメラユニットは、カメラレンズ2およびベース50(カラーセンサ素子70を備えた基板)を備えるカメラ1、レンズキャップ3、レンズ側ベース4を備える。レンズ側ベース4には、カメラレンズ孔5、光源レンズ孔6、光源レンズ7、が配されている。レンズ側ベース4には、レンズキャップ3を装着したカメラレンズ2が通る寸法のカメラレンズ孔が設けられている。レンズキャップ3は、カメラレンズ2に装着される有底筒状であり、底部31と側面32を備える。側面32を挟んだ底部31の反対側は開口している。光源レンズ孔6のカメラ1側(図1中、上側)には、光源(不図示)が配される。
The camera unit includes a camera 1 having a camera lens 2 and a base 50 (a substrate having a color sensor element 70), a lens cap 3, and a lens side base 4. A camera lens hole 5, a light source lens hole 6, and a light source lens 7 are arranged in the lens side base 4. The lens side base 4 is provided with a camera lens hole 5 having a size through which the camera lens 2 with the lens cap 3 attached passes. The lens cap 3 is a bottomed cylindrical shape that is attached to the camera lens 2, and includes a bottom 31 and a side surface 32. The opposite side of the bottom 31 across the side surface 32 is open. A light source (not shown) is arranged on the camera 1 side of the light source lens hole 6 (upper side in FIG. 1 ).

図2はカメラ1の側面図である。カメラレンズ2側周には、レンズマウント9とレンズ支持部8が設けられている。レンズキャップ3の側面32の内面が、レンズマウント9の側面に対向するようにして例えば摺動しつつ遊嵌し、レンズキャップ3はカメラレンズ2に装着される。レンズキャップ3の開口側縁は、レンズマウント9よりも径寸法が大きいレンズ支持部8に当接し、図2中、上方向への移動を規制される。レンズキャップ3の脱落を防止するために、テープ等でレンズキャップ3とカメラレンズ2が固定されてもよい。 Fig. 2 is a side view of the camera 1. A lens mount 9 and a lens support portion 8 are provided around the periphery of the camera lens 2. The inner surface of a side surface 32 of the lens cap 3 faces the side surface of the lens mount 9, and the lens cap 3 is attached to the camera lens 2, for example, by loosely fitting while sliding. The opening side edge of the lens cap 3 abuts against the lens support portion 8, which has a larger diameter than the lens mount 9, and the upward movement in Fig. 2 is restricted. To prevent the lens cap 3 from falling off, the lens cap 3 and the camera lens 2 may be fixed with tape or the like.

図3は、カメラユニット100のカメラレンズ2にレンズキャップ3を取り付けた状態の斜視図である。カメラレンズ孔5の孔寸法は、レンズキャップ3が通過できる寸法として設定されており、カメラ1のベース50がレンズ側ベース4を通過できない寸法として設定されている。図6に示すように、ベース50は、レンズ側ベース4の内側に設けられたリブ41に載置され、ネジ等の固定部材60により固定される。このため、カメラレンズ2をカメラレンズ孔5に挿通して組み立てる際、予めレンズキャップ3をカメラレンズ2に装着して保護してから、図6中、上方からカメラユニット100をレンズ側ベース4に装着できる。具体的には、カメラレンズ2とレンズキャップ3とがカメラレンズ孔5を通過するように挿通作業される。カメラレンズ孔5への挿通作業前にレンズキャップ3を装着することで、例えば挿通作業でのカメラレンズ2の傷つきを抑制できる。 3 is a perspective view of the state in which the lens cap 3 is attached to the camera lens 2 of the camera unit 100. The hole dimensions of the camera lens hole 5 are set to allow the lens cap 3 to pass through, and are set to allow the base 50 of the camera 1 to not pass through the lens side base 4. As shown in FIG. 6, the base 50 is placed on a rib 41 provided on the inside of the lens side base 4 and fixed by a fixing member 60 such as a screw. Therefore, when assembling the camera lens 2 by inserting it into the camera lens hole 5, the lens cap 3 is attached to the camera lens 2 in advance to protect it, and then the camera unit 100 can be attached to the lens side base 4 from above in FIG. 6. Specifically, the camera lens 2 and the lens cap 3 are inserted so that they pass through the camera lens hole 5. By attaching the lens cap 3 before the insertion operation into the camera lens hole 5, for example, damage to the camera lens 2 during the insertion operation can be suppressed.

図4は、レンズ側ベース4に第1保護部材10を貼り付ける説明をする図である。第1保護部材10は例えば透光性のある材料で形成されたシート状であり、カメラレンズ孔5又は光源レンズ孔6の少なくとも一方を覆わない構造となっている。すなわち、レンズ側ベース4に第1保護部材10が貼付された場合に、カメラレンズ孔5に対応する領域に開けられた孔としてのカメラレンズ露出孔101と、光源レンズ孔6に対応する領域に開けられた孔としての光源レンズ露出孔102とを有する。 Figure 4 is a diagram illustrating the attachment of the first protective member 10 to the lens side base 4. The first protective member 10 is, for example, in the form of a sheet made of a light-transmitting material, and is structured so as not to cover at least one of the camera lens hole 5 or the light source lens hole 6. In other words, when the first protective member 10 is attached to the lens side base 4, it has a camera lens exposure hole 101 as a hole opened in the area corresponding to the camera lens hole 5, and a light source lens exposure hole 102 as a hole opened in the area corresponding to the light source lens hole 6.

カメラユニット100の製造者は、第1保護部材10をレンズ側ベース4に取り付けた後で、光源レンズ7及びカメラレンズ2が正常に取り付けられているか否かを確認する検査工程を実行する。その際、カメラレンズ孔5や光源レンズ孔6が第1保護部材10で覆われていると、確認ミスの虞が増加すると考えられる。このため、これら領域の一方好ましくは両方に孔101,102が位置するようにする。 After attaching the first protective member 10 to the lens side base 4, the manufacturer of the camera unit 100 performs an inspection process to check whether the light source lens 7 and the camera lens 2 are attached properly. If the camera lens hole 5 and the light source lens hole 6 are covered by the first protective member 10, the risk of checking incorrectly increases. For this reason, holes 101 and 102 are positioned in one or, preferably, both of these areas.

図5は、カメラユニット100とこれを備える家電製品(例えば冷蔵庫)がユーザの家庭に据え付けられた直後の状態を示す図であり、第1保護部材10、第2保護部材11、及びレンズキャップ3を外す際の図である。 Figure 5 shows the state immediately after the camera unit 100 and a home appliance (e.g., a refrigerator) equipped with it have been installed in a user's home, with the first protective member 10, the second protective member 11, and the lens cap 3 removed.

カメラユニット100の製造者は、製造工場からの出荷からユーザの家庭までの輸送過程での傷つきを防止すべく、第2保護部材11をカメラユニット100に装着している。第2保護部材11は、光源レンズ孔6及びレンズキャップ3を跨いで貼付されている。第2保護部材11がユーザ等の手指300によってゆっくり剥離されると、第2保護部材11とともにレンズキャップ3及び第1保護部材10がレンズ側ベース4から取り外される構造となっている。 The manufacturer of the camera unit 100 attaches the second protective member 11 to the camera unit 100 to prevent damage during shipping from the manufacturing factory to the user's home. The second protective member 11 is attached across the light source lens hole 6 and the lens cap 3. When the second protective member 11 is slowly peeled off by the user's fingers 300, the lens cap 3 and the first protective member 10 are removed from the lens side base 4 together with the second protective member 11.

本実施形態では、家電製品として冷蔵庫を示したが、カメラユニット100が装着される家電製品であれば特に制限されない。例えば電気掃除機、空気調和機、加熱調理器、洗濯機等でもよい。 In this embodiment, a refrigerator is shown as an example of a home appliance, but there is no particular limitation as long as the home appliance can be equipped with a camera unit 100. For example, it may be a vacuum cleaner, an air conditioner, a cooking appliance, a washing machine, etc.
