Members 81 and 82 are provided.

各保持部材８１，８２は、対応する回路基板７１，７２の長さ方向の端部を保持している。これにより、各回路基板７１，７２は、基板配置面５９において当該回路基板７１，７２の左右の端部に対応する箇所にそれぞれ設けられた保持部材８１，８２によって保持されている。   Each holding member 81, 82 holds the end of the corresponding circuit board 71, 72 in the length direction. Accordingly, the circuit boards 71 and 72 are held by holding members 81 and 82 provided at locations corresponding to the left and right ends of the circuit boards 71 and 72 on the board placement surface 59, respectively.

複数の保持部材８１，８２は、左右の回路基板７１，７２の間に設けられた第１の保持部材８１と、一方回路基板７１の左側端部および他方回路基板７２の右側端部のそれぞれに設けられた第２の保持部材８２とを含む。すなわち、第１の保持部材８１と第２の保持部材８２は、左右方向において交互に設けられている。   The plurality of holding members 81, 82 are provided on the first holding member 81 provided between the left and right circuit boards 71, 72, and the left end of one circuit board 71 and the right end of the other circuit board 72, respectively. And a second holding member 82 provided. That is, the first holding member 81 and the second holding member 82 are provided alternately in the left-right direction.

Further, the ends of the left and right circuit boards 71 and 72 opposite to the first holding members 81 are held by the corresponding second holding members 82.

図７に示されるように、第１の保持部材８１は、ボス部８４を備えている。ボス部８４は上下両側が開口した円筒状に形成されており、上下方向に貫通したねじ挿通孔８５を備えている。第１の保持部材８１は、ねじ挿通孔８５に下方（基板配置面５９とは反対側）から挿入したねじ８６を上片部５５にねじ込むことで、放熱部材５１に取り付けられている。   As shown in FIG. 7, the first holding member 81 includes a boss portion 84. The boss portion 84 is formed in a cylindrical shape with both upper and lower sides opened, and includes a screw insertion hole 85 penetrating in the vertical direction. The first holding member 81 is attached to the heat dissipation member 51 by screwing a screw 86 inserted into the screw insertion hole 85 from below (the side opposite to the substrate placement surface 59) into the upper piece portion 55.

ここで、第１の保持部材８１は、上下方向（回路基板７１，７２の厚み方向）に見たときに、放熱部材５１において左右の回路基板７１，７２同士を接続した配線７４と重ならない箇所に設けられている。このため、第１の保持部材８１をねじ８６により放熱部材５１に取り付けるときには、左右の回路基板７１，７２を接続した配線７４が、第１の保持部材８１と放熱部材５１との間に挟まれにくい。   Here, when the first holding member 81 is viewed in the vertical direction (thickness direction of the circuit boards 71 and 72), the heat radiation member 51 does not overlap the wiring 74 connecting the left and right circuit boards 71 and 72. Is provided. For this reason, when the first holding member 81 is attached to the heat dissipation member 51 with the screw 86, the wiring 74 connecting the left and right circuit boards 71 and 72 is sandwiched between the first holding member 81 and the heat dissipation member 51. Hateful.

第１の保持部材８１は、ボス部８４の下部から左右両側に突出した押さえ部９１，９２をさらに備えている。以下、必要に応じて、ボス部８４の左側（一方回路基板７１側）に位置した押さえ部９１を第１の押さえ部９１といい、ボス部８４の右側（他方回路基板７２側）に位置した押さえ部９２を第２の押さえ部９２という。   The first holding member 81 further includes pressing portions 91 and 92 that protrude from the lower portion of the boss portion 84 to the left and right sides. Hereinafter, if necessary, the holding portion 91 located on the left side (one circuit board 71 side) of the boss portion 84 is referred to as a first holding portion 91, and is located on the right side (other circuit board 72 side) of the boss portion 84. The pressing portion 92 is referred to as a second pressing portion 92.

第１の押さえ部９１と基板配置面５９の間には、一方回路基板７１の右側（第１の保持部材８１側）の端部が位置している。一方回路基板７１の右側の端面は、ボス部８４に対向している。一方回路基板７１の右側端部の下面（基板配置面５９と反対側の面）は、第１の押さえ部９１に対向している。   Between the first pressing portion 91 and the substrate placement surface 59, the end portion on the right side (first holding member 81 side) of the one circuit board 71 is located. On the other hand, the right end surface of the circuit board 71 faces the boss portion 84. On the other hand, the lower surface (surface opposite to the substrate placement surface 59) of the right end portion of the circuit board 71 faces the first pressing portion 91.

他方回路基板７２の左側（第１の保持部材８１側）の端部は、第２の押さえ部９２と基板配置面５９の間に位置している。他方回路基板７２の左側の端面は、ボス部８４に対向している。他方回路基板７２の左側端部の下面は、第２の押さえ部９２に対向している。   On the other hand, the end portion on the left side (first holding member 81 side) of the circuit board 72 is located between the second pressing portion 92 and the substrate placement surface 59. On the other hand, the left end surface of the circuit board 72 faces the boss portion 84. On the other hand, the lower surface of the left end portion of the circuit board 72 faces the second pressing portion 92.

第１の保持部材８１が備えたボス部８４の左右の壁部８７，８８のそれぞれは、対応する回路基板７１，７２がその長手方向における外側に向かって移動することを規制する第１の移動規制部を構成している。また、第１の押さえ部９１および第２の押さえ部９２のそれぞれは、対応する回路基板７１，７２が下方（基板配置面５９とは反対側）に向かって移動することを規制する第２の移動規制部を構成している。   Each of the left and right wall portions 87 and 88 of the boss portion 84 provided in the first holding member 81 is a first movement that restricts the corresponding circuit boards 71 and 72 from moving outward in the longitudinal direction. It constitutes the regulation section. Each of the first pressing part 91 and the second pressing part 92 restricts the movement of the corresponding circuit boards 71 and 72 downward (on the side opposite to the board placement surface 59). It constitutes the movement restriction part.

一方回路基板７１の右側端部は、前述のようにボス部８４の左側の壁部８７（第１の移動規制部）および第１の押さえ部９１（第２の移動規制部）によって移動が規制されることで、第１の保持部材８１に保持されている。すなわち、本実施形態の第１の保持部材８１の左側には、ボス部８４の左側の壁部８７と第１の押さえ部９１によって構成された保持部８９が設けられており、この保持部８９によって一方回路基板７１の右側端部が保持されている。以下、この保持部８９を一方保持部８９という。   On the other hand, the movement of the right end portion of the circuit board 71 is restricted by the left wall portion 87 (first movement restricting portion) and the first pressing portion 91 (second movement restricting portion) of the boss portion 84 as described above. As a result, the first holding member 81 holds it. That is, on the left side of the first holding member 81 of the present embodiment, a holding portion 89 constituted by the left wall portion 87 of the boss portion 84 and the first pressing portion 91 is provided. Thus, the right end of the one circuit board 71 is held. Hereinafter, this holding portion 89 is referred to as one holding portion 89.

また、他方回路基板７２の左側端部は、前述のようにボス部８４の右側の壁部８８（第１の移動規制部）および第２の押さえ部９２（第２の移動規制部）によって移動が規制されることで、第１の保持部材８１に保持されている。すなわち、本実施形態の第１の保持部材８１の右側には、ボス部８４の右側の壁部８８と第２の押さえ部９２によって構成された保持部９０が設けられており、この保持部９０によって他方回路基板７２の左側端部が保持されている。以下、この保持部９０を他方保持部９０という。すなわち、本実施形態の第１の保持部材８１は、一方保持部８９と、一方保持部８９と一体に形成された他方保持部９０とを備えた部材である。なお、一方保持部８９と他方保持部９０は、別体であってもよい。   Further, the left end portion of the other circuit board 72 is moved by the right wall portion 88 (first movement restricting portion) and the second pressing portion 92 (second movement restricting portion) of the boss portion 84 as described above. Is held by the first holding member 81. That is, on the right side of the first holding member 81 of the present embodiment, a holding portion 90 constituted by the right wall portion 88 of the boss portion 84 and the second pressing portion 92 is provided. Thus, the left end of the other circuit board 72 is held. Hereinafter, the holding unit 90 is referred to as the other holding unit 90. That is, the first holding member 81 of this embodiment is a member that includes one holding portion 89 and the other holding portion 90 that is formed integrally with the one holding portion 89. The one holding part 89 and the other holding part 90 may be separate.

図６Ａに示されるように、放熱部材５１において各回路基板７１，７２の第１の保持部材８１とは反対側の端部に対応する箇所に設けられた第２の保持部材８２は、第１の保持部材８１と基本的な構成要素が同じである。このため、以下では、各第２の保持部材８２において第１の保持部材８１と共通する構成要素については同一の符号を付してその説明を省略する。   As shown in FIG. 6A, the second holding member 82 provided at a location corresponding to the end of the heat dissipation member 51 opposite to the first holding member 81 of each circuit board 71, 72 has the first The holding member 81 has the same basic components. For this reason, below, the same code | symbol is attached | subjected about the component which is common in the 1st holding member 81 in each 2nd holding member 82, and the description is abbreviate | omitted.

各第２の保持部材８２は、図８に示されるように、ボス部８４の上端部から前後両側に突出した回転規制部９３，９４を備えている。ここで、作業者が第２の保持部材８２をねじ８６によって放熱部材５１に取り付けるにあたって、ねじ挿通孔８５に挿通したねじ８６を放熱部材５１にねじ込むとき、当該第２の保持部材８２はねじ８６と共に上下軸回りに回転する可能性がある。しかし、本実施形態では、第２の保持部材８２の前後の回転規制部９３，９４が、対応する回路基板７１，７２の第１の保持部材８１とは反対側の端面に接触し、これにより第２の保持部材８２の前記回転が規制される。このため、作業者は、第２の保持部材８２を放熱部材５１に簡単に取り付けることができる。なお、第２の保持部材８２は、対応する回路基板７１，７２の第１の保持部材８１側の端部が第１の保持部材８１によって保持された状態で、放熱部材５１に取り付けられる。このため、前述のように第２の保持部材８２の回転規制部９３，９４が対応する回路基板７１，７２の端面に接触しても、当該回路基板７１，７２は動きにくくなっている。   As shown in FIG. 8, each second holding member 82 includes rotation restricting portions 93 and 94 that protrude from the upper end portion of the boss portion 84 to the front and rear sides. Here, when the operator attaches the second holding member 82 to the heat radiating member 51 with the screw 86, when the screw 86 inserted into the screw insertion hole 85 is screwed into the heat radiating member 51, the second holding member 82 is screwed into the screw 86. At the same time, it may rotate around the vertical axis. However, in this embodiment, the front and rear rotation restricting portions 93 and 94 of the second holding member 82 are in contact with the end surfaces of the corresponding circuit boards 71 and 72 opposite to the first holding member 81, thereby The rotation of the second holding member 82 is restricted. For this reason, the operator can easily attach the second holding member 82 to the heat radiating member 51. The second holding member 82 is attached to the heat radiating member 51 in a state where the end of the corresponding circuit boards 71 and 72 on the first holding member 81 side is held by the first holding member 81. For this reason, even if the rotation restricting portions 93 and 94 of the second holding member 82 come into contact with the corresponding end surfaces of the circuit boards 71 and 72 as described above, the circuit boards 71 and 72 are difficult to move.

各第２の保持部材８２は、ボス部８４の対応する回路基板７１，７２側の壁部８７，８８によって、当該回路基板７１，７２がその長手方向における外側に向かって移動することを規制する。また、各第２の保持部材８２は、対応する回路基板７１，７２側の押さえ部９１，９２により、当該回路基板７１，７２が下方に向かって移動することを規制する。これにより、各回路基板７１，７２の第１の保持部材８１とは反対側の端部が対応する第２の保持部材８２により保持されている。すなわち、本実施形態の第２の保持部材８２は、左右両側の保持部８９，９０のうちの一方の保持部８９，９０を用いて対応する回路基板７１，７２の端部を保持している。   Each of the second holding members 82 restricts the circuit boards 71 and 72 from moving outward in the longitudinal direction by the corresponding wall parts 87 and 88 on the circuit board 71 and 72 side of the boss part 84. . Each of the second holding members 82 restricts the circuit boards 71 and 72 from moving downward by the pressing parts 91 and 92 on the corresponding circuit boards 71 and 72 side. As a result, the end of each circuit board 71, 72 opposite to the first holding member 81 is held by the corresponding second holding member 82. That is, the second holding member 82 of the present embodiment holds the end portions of the corresponding circuit boards 71 and 72 using one of the holding portions 89 and 90 on the left and right sides. .

なお、本実施形態の第２の保持部材８２は、左右両側に保持部８９，９０が形成されているが、対応する回路基板７１，７２側にのみ保持部８９，９０が形成されてもよい。   In the second holding member 82 of the present embodiment, the holding portions 89 and 90 are formed on the left and right sides, but the holding portions 89 and 90 may be formed only on the corresponding circuit boards 71 and 72 side. .

図６Ｂに示されるように、左右方向において隣り合う保持部材８１，８２のボス部８４同士の間隔Ｌ１は、当該両保持部材８１，８２の間に配置される回路基板７１，７２の左右方向の長さＬ２よりも大きい。このため、当該両保持部材８１，８２のうちの少なくとも一方の保持部材８１，８２のボス部８４と、これに対応する回路基板７１，７２の長さ方向の端面との間には、図９に示されるような隙間８３が形成される。この隙間８３は、対応する回路基板７１，７２の左右方向の熱膨張を許容する。このような隙間８３を設けることで、回路基板７１，７２が左右方向に熱膨張したときに、当該回路基板７１，７２の左右両端面が対応する保持部材８１，８２に接触して当該回路基板７１，７２が反るといった事態が生じにくい。すなわち、隣り合う保持部材８１，８２のボス部８４の間隔Ｌ１から、両保持部材８１，８２の間に配置される回路基板７１，７２の長さＬ２を減じた寸法Ｌ３（Ｌ３＝Ｌ１−Ｌ２）は、当該回路基板７１，７２の左右方向の熱膨張を許容できる寸法である。   As shown in FIG. 6B, the distance L1 between the boss portions 84 of the holding members 81 and 82 adjacent in the left-right direction is the left-right direction of the circuit boards 71, 72 arranged between the both holding members 81, 82. It is larger than the length L2. For this reason, between the boss portions 84 of at least one of the holding members 81 and 82 and the end surfaces in the length direction of the circuit boards 71 and 72 corresponding thereto, FIG. A gap 83 is formed as shown in FIG. The gap 83 allows thermal expansion of the corresponding circuit boards 71 and 72 in the left-right direction. By providing such a gap 83, when the circuit boards 71, 72 are thermally expanded in the left-right direction, the left and right end surfaces of the circuit boards 71, 72 come into contact with the corresponding holding members 81, 82, and the circuit boards It is difficult for the situation where 71 and 72 warp. That is, the dimension L3 (L3 = L1-L2) obtained by subtracting the length L2 of the circuit boards 71, 72 disposed between the holding members 81, 82 from the distance L1 between the boss portions 84 of the adjacent holding members 81, 82. ) Is a dimension that allows the thermal expansion of the circuit boards 71 and 72 in the left-right direction.

各保持部材８１，８２の左右の押さえ部９１，９２は、図９に示されるように、基板配置面５９までの上下寸法が、対応する回路基板７１，７２の厚みよりも大きい。このため、各回路基板７１，７２の左右両端部のそれぞれの上面と、対応する押さえ部９１の下面との間には、隙間９５が形成されるようになっている。この隙間９５は、対応する回路基板７１，７２の上下方向の熱膨張を許容する。なお、前述した寸法Ｌ３は、各回路基板７１，７２の左右方向の熱膨張量が上下方向の熱膨張量よりも大きいことを考慮して、隙間９５の上下寸法よりも大きく設定されることが好ましい。   As shown in FIG. 9, the left and right pressing portions 91 and 92 of the holding members 81 and 82 have a vertical dimension up to the board placement surface 59 larger than the thickness of the corresponding circuit boards 71 and 72. For this reason, a gap 95 is formed between the upper surfaces of the left and right end portions of each circuit board 71 and 72 and the lower surface of the corresponding pressing portion 91. This gap 95 allows the thermal expansion of the corresponding circuit boards 71 and 72 in the vertical direction. The dimension L3 described above may be set larger than the vertical dimension of the gap 95 in consideration of the fact that the thermal expansion amount in the left-right direction of each circuit board 71, 72 is larger than the thermal expansion amount in the vertical direction. preferable.

なお、本実施形態の保持具８は、各回路基板７１，７２の左右方向の膨張を許容するための隙間６２を介して複数の回路基板７１，７２を保持しているが、保持具８はこれに制限されない。保持具８は、例えば各回路基板７１，７２を左右方向にスライド可能に保持する保持部材を備え、これら保持部材で複数の回路基板７１，７２を保持するものであってもよい。   Note that the holder 8 of the present embodiment holds the plurality of circuit boards 71 and 72 via gaps 62 for allowing the circuit boards 71 and 72 to expand in the left-right direction. This is not a limitation. The holder 8 may include, for example, a holding member that holds the circuit boards 71 and 72 so as to be slidable in the left-right direction, and may hold the plurality of circuit boards 71 and 72 with these holding members.

図４に示されるように、放熱部材５１の溝部５８の下開口部６３は、収納位置に位置した昇降棚４の下面と略同じ高さに位置している。溝部５８の下開口部６３には、当該下開口部６３を塞いで、溝部５８の内側にごみや埃等が入り込むことを抑制するカバー５２が設けられている。   As shown in FIG. 4, the lower opening 63 of the groove 58 of the heat radiating member 51 is located at substantially the same height as the lower surface of the elevating shelf 4 located at the storage position. The lower opening 63 of the groove 58 is provided with a cover 52 that closes the lower opening 63 and suppresses dirt, dust, and the like from entering the groove 58.

カバー５２は、各回路基板７１，７２の下方に位置している。カバー５２は、透光性を有しており、各回路基板７１，７２の光源部７３から下方に照射された光は、カバー５２を透過する。   The cover 52 is located below the circuit boards 71 and 72. The cover 52 has translucency, and the light irradiated downward from the light source unit 73 of each circuit board 71, 72 is transmitted through the cover 52.

カバー５２は、各回路基板７１，７２の光源部７３から照射された光を拡散する。このため、各回路基板７１，７２の光源部７３から下方に照射された光は、カバー５２にて均一化された後、カバー５２の下方に出る。なお、本実施形態のカバー５２は乳白色に着色されているが、その他の色が着色されてもよいし、無色であってもよい。また、カバー５２は、光源部７３からの光を後方や前方に傾けて出射する機能などを備えてもよい。また、カバー５２は省略可能である。   The cover 52 diffuses light emitted from the light source unit 73 of each circuit board 71, 72. For this reason, the light irradiated downward from the light source unit 73 of each circuit board 71, 72 is made uniform by the cover 52 and then exits below the cover 52. In addition, although the cover 52 of this embodiment is colored milky white, other colors may be colored and may be colorless. The cover 52 may have a function of emitting light from the light source unit 73 by tilting it backward or forward. Further, the cover 52 can be omitted.

照明装置５による照明の入切は、利用者による操作部３６の操作に応じて切り替えられる。利用者が操作部３６を操作することで、照明装置５の各回路基板７１，７２の光源部７３（複数の発光素子７５）は発光する。このように各回路基板７１，７２の光源部７３が発光すると、各回路基板７１，７２の光源部７３から発せられた光は、カバー５２を透って、収納部５３の下方に出射する。この光はカバー５２の左右方向に延びた広い領域から出射され、この光により収納庫２の下方が広範囲にわたって照明される。   The lighting device 5 is switched on and off according to the operation of the operation unit 36 by the user. When the user operates the operation unit 36, the light source units 73 (the plurality of light emitting elements 75) of the circuit boards 71 and 72 of the illumination device 5 emit light. When the light source unit 73 of each circuit board 71 and 72 emits light in this way, the light emitted from the light source unit 73 of each circuit board 71 and 72 is emitted through the cover 52 and below the storage unit 53. This light is emitted from a wide area extending in the left-right direction of the cover 52, and the light below the storage 2 is illuminated over a wide range.

放熱部材５１の前方には、前述した幕板３５が位置している。幕板３５は、放熱部材５１の前面に沿っている。幕板３５は、例えばねじ止めと掛止により放熱部材５１に固定される。なお、幕板３５は、接着剤等を用いて放熱部材５１に取り付けられてもよい。   The above-described curtain plate 35 is located in front of the heat radiating member 51. The curtain plate 35 is along the front surface of the heat dissipation member 51. The curtain plate 35 is fixed to the heat dissipation member 51 by, for example, screwing and hooking. The curtain plate 35 may be attached to the heat radiating member 51 using an adhesive or the like.

幕板３５は、左右方向に延びた長尺部材である。幕板３５は、金属製であって、具体的にはアルミニウム製である。なお、幕板３５は、例えば合成樹脂や木材等のその他の材料から形成されてもよい。   The curtain plate 35 is a long member extending in the left-right direction. The curtain plate 35 is made of metal, specifically, aluminum. The curtain plate 35 may be formed of other materials such as synthetic resin and wood.

幕板３５は、前板３１の下方に位置した溝状部３７と、前板３１の下端部後方に位置した板状部３８とを備えている。   The curtain plate 35 includes a groove-like portion 37 located below the front plate 31 and a plate-like portion 38 located behind the lower end portion of the front plate 31.

溝状部３７は、放熱部材５１の前面および前板３１の下端面に沿って左右方向に延びている。溝状部３７は、長手方向と直交した断面形状が後方に開口した断面略Ｃ字状（コ字状）に形成されている。溝状部３７の上面は、前板３１の下端面に接し、溝状部３７の前面は、前板３１の前面と略面一である。溝状部３７の前面には、前述した操作部３６が設けられている。   The groove-shaped portion 37 extends in the left-right direction along the front surface of the heat radiating member 51 and the lower end surface of the front plate 31. The groove-shaped portion 37 is formed in a substantially C-shaped (C-shaped) cross section in which a cross-sectional shape orthogonal to the longitudinal direction is opened rearward. The upper surface of the groove-shaped portion 37 is in contact with the lower end surface of the front plate 31, and the front surface of the groove-shaped portion 37 is substantially flush with the front surface of the front plate 31. The operation unit 36 described above is provided on the front surface of the groove portion 37.

板状部３８は、溝状部３７の上面部の後縁部から上方に向かって突出している。板状部３８の後面は、放熱部材５１の突片部５４の前面に接しており、これにより、幕板３５は放熱部材５１に熱的に接続されている。   The plate-like portion 38 protrudes upward from the rear edge portion of the upper surface portion of the groove-like portion 37. The rear surface of the plate-like portion 38 is in contact with the front surface of the projecting piece portion 54 of the heat radiating member 51, whereby the curtain plate 35 is thermally connected to the heat radiating member 51.

前述の照明装置５による照明が行われたとき、各光源部７３や各回路基板７１，７２で発生した熱は、放熱部材５１に伝わり、放熱部材５１で放散される。また、放熱部材５１の熱の一部は、幕板３５に伝わってこの幕板３５においても放散される。従って、発光装置７は高温になりにくい。   When illumination is performed by the illumination device 5 described above, the heat generated in each light source unit 73 and each circuit board 71, 72 is transmitted to the heat radiating member 51 and dissipated by the heat radiating member 51. Further, a part of the heat of the heat radiating member 51 is transmitted to the curtain plate 35 and is also dissipated in the curtain plate 35. Therefore, the light emitting device 7 is unlikely to become high temperature.

また、照明装置５の発光装置７は、放熱部材５１に収納され、かつこの放熱部材５１の表面において収納庫２内に臨む部分は、遮熱部材５０によって覆われている。このため、加熱装置２０により収納庫２内に発生した熱は、遮熱部材５０および放熱部材５１により遮られて発光装置７に伝わりにくい。   The light emitting device 7 of the lighting device 5 is housed in the heat radiating member 51, and the portion of the surface of the heat radiating member 51 that faces the storage 2 is covered with the heat shield member 50. For this reason, the heat generated in the storage 2 by the heating device 20 is blocked by the heat shielding member 50 and the heat radiating member 51 and is not easily transmitted to the light emitting device 7.

また、本実施形態の発光装置７は、図６Ａに示されるように、左右方向に並ぶ複数の回路基板７１，７２を備えているため、回路基板７１，７２が長手方向に熱膨張したときに反りにくい。例えば発光装置７が、本実施形態の回路基板７１，７２の２枚分の長さを有する回路基板を一枚のみ備え、この回路基板が本実施形態と同様に、保持具８により長手方向の両端部が保持されているとする。この場合、回路基板は長手方向に大きく熱膨張し、当該回路基板の長手方向の両端部が保持部材８１に接触して回路基板が反る可能性がある。このように回路基板が反ると、回路基板の基板配置面５９との接触面積が小さくなり、発光装置７の放熱効率が低下する可能性もある。また、この回路基板の長手方向の両端部と対応する保持部材８１との間の隙間８３の左右寸法を大きくすれば、回路基板の反りは生じにくくなる。しかし、この場合は、回路基板が左右方向に大きく移動しやすくなり、保持具８により回路基板をしっかりと保持することが難しい。これに対して、本実施形態の発光装置７は、左右方向に並ぶ複数の回路基板７１，７２を備えているので、回路基板７１，７２一枚当たりの左右方向の熱膨張量は小さくなる。従って、保持具８により各回路基板７１，７２はしっかりと保持され、かつ各回路基板７１，７２の反りの発生が抑制される。   Further, as shown in FIG. 6A, the light-emitting device 7 of the present embodiment includes a plurality of circuit boards 71 and 72 arranged in the left-right direction. Therefore, when the circuit boards 71 and 72 are thermally expanded in the longitudinal direction. Hard to warp. For example, the light-emitting device 7 includes only one circuit board having a length corresponding to two of the circuit boards 71 and 72 of the present embodiment, and this circuit board is moved in the longitudinal direction by the holder 8 as in the present embodiment. Assume that both ends are held. In this case, there is a possibility that the circuit board greatly expands in the longitudinal direction, and both ends in the longitudinal direction of the circuit board come into contact with the holding member 81 and the circuit board is warped. When the circuit board is warped in this way, the contact area of the circuit board with the board placement surface 59 is reduced, and the heat dissipation efficiency of the light emitting device 7 may be reduced. Further, if the left and right dimensions of the gap 83 between the both ends in the longitudinal direction of the circuit board and the corresponding holding member 81 are increased, the circuit board is less likely to warp. However, in this case, the circuit board easily moves greatly in the left-right direction, and it is difficult to hold the circuit board firmly by the holder 8. On the other hand, since the light emitting device 7 of the present embodiment includes the plurality of circuit boards 71 and 72 arranged in the left-right direction, the amount of thermal expansion in the left-right direction per circuit board 71, 72 is reduced. Accordingly, the circuit boards 71 and 72 are firmly held by the holder 8 and the occurrence of warpage of the circuit boards 71 and 72 is suppressed.

以上説明した本実施形態の収納装置１は、以下の特徴を有している。収納装置１は、物品を収納可能な収納庫２と、収納庫２に収納された物品を加熱する加熱装置２０と、収納庫２に設けられた照明装置５とを備える。照明装置５は、一方向に延びた放熱部材５１と、複数の回路基板７１，７２と、各回路基板７１，７２に設けられた光源部７３とを備える。放熱部材５１は、その長手方向に沿う一面である基板配置面５９を備える。複数の回路基板７１，７２は、放熱部材５１の長手方向に並べて設けられる。各回路基板７１，７２は、基板配置面５９に沿って放熱部材５１の長手方向に延びた板状に形成される。照明装置５は、放熱部材５１に設けられて複数の回路基板７１，７２を各回路基板７１，７２の長手方向の膨張を許容しつつ保持する保持具８をさらに備える。   The storage device 1 of the present embodiment described above has the following characteristics. The storage device 1 includes a storage 2 that can store articles, a heating device 20 that heats articles stored in the storage 2, and a lighting device 5 provided in the storage 2. The illuminating device 5 includes a heat dissipation member 51 extending in one direction, a plurality of circuit boards 71 and 72, and a light source unit 73 provided on each circuit board 71 and 72. The heat radiating member 51 includes a substrate arrangement surface 59 that is one surface along the longitudinal direction thereof. The plurality of circuit boards 71 and 72 are provided side by side in the longitudinal direction of the heat dissipation member 51. Each of the circuit boards 71 and 72 is formed in a plate shape extending in the longitudinal direction of the heat dissipation member 51 along the board placement surface 59. The illuminating device 5 further includes a holder 8 that is provided on the heat dissipation member 51 and holds the plurality of circuit boards 71 and 72 while allowing the circuit boards 71 and 72 to expand in the longitudinal direction.

この特徴を有する収納装置１は、加熱装置２０により発生した熱が照明装置５に伝わったとしても、この熱は放熱部材５１により放散される。このため、発光装置７が高温になって故障等の不具合が生じることが抑制される。また、保持具８は、複数の回路基板７１，７２を各回路基板７１，７２の長手方向の熱膨張を許容しつつ保持する。このため、仮に加熱装置２０により発生した熱が回路基板７１，７２に伝わって回路基板７１，７２が熱膨張したとしても、各回路基板７１，７２は反りにくい。また、発光装置７は、左右方向に並ぶ複数の回路基板７１，７２を備えている。このため、前述したように、回路基板を一枚のみ備える場合と比較して、保持具８により各回路基板７１，７２がしっかりと保持され、かつ各回路基板７１，７２の反りの発生が抑制される。   In the storage device 1 having this feature, even if the heat generated by the heating device 20 is transmitted to the lighting device 5, this heat is dissipated by the heat radiating member 51. For this reason, it is suppressed that malfunctions, such as a failure, will arise because the light-emitting device 7 becomes high temperature. The holder 8 holds the plurality of circuit boards 71 and 72 while allowing thermal expansion in the longitudinal direction of the circuit boards 71 and 72. For this reason, even if the heat generated by the heating device 20 is transmitted to the circuit boards 71 and 72 and the circuit boards 71 and 72 are thermally expanded, the circuit boards 71 and 72 are not easily warped. The light emitting device 7 includes a plurality of circuit boards 71 and 72 arranged in the left-right direction. Therefore, as described above, the circuit boards 71 and 72 are firmly held by the holder 8 and the occurrence of warpage of the circuit boards 71 and 72 is suppressed as compared with the case where only one circuit board is provided. Is done.

The holder 8 is provided at a position corresponding to each of the longitudinal ends of the circuit boards 71 and 72 on the board placement surface 59 and holds the longitudinal ends of the corresponding circuit boards 71 and 72. Parts 89 and 90 are provided. Each holding part 89 and 90 includes a first movement restricting part (wall parts 87 and 88 of the boss part 84) and a second movement restricting part (pressing parts 91 and 92). The first movement restricting portion faces the end face in the longitudinal direction of the corresponding circuit board 71, 72, and restricts the circuit board 71, 72 from moving outward in the longitudinal direction. The second movement restricting portion faces the surface opposite to the substrate placement surface 59 at the end in the longitudinal direction of the corresponding circuit board 71, 72, and the circuit board 71, 72 is opposite to the substrate placement surface 59. To move to the side. The holding portions 89 and 90 that hold at least one end of both end portions in the longitudinal direction of the circuit boards 71 and 72 are end faces in the longitudinal direction of the first movement restricting portions and the corresponding circuit boards 71 and 72, respectively. Are provided so that a gap 83 is formed between them.

この特徴を有する収納装置１は、各回路基板７１，７２の長手方向の端部が対応する保持部８９，９０により保持される。すなわち、各保持部８９，９０は、第１の移動規制部により対応する回路基板７１，７２が長手方向の外側に移動することを規制する。また、各保持部８９，９０は、第２の移動規制部により当該回路基板７１，７２が基板配置面５９とは反対側に移動することを規制する。そして、これにより、各保持部８９，９０により対応する回路基板７１，７２の長手方向の端部が保持される。   In the storage device 1 having this feature, the end portions in the longitudinal direction of the circuit boards 71 and 72 are held by the corresponding holding portions 89 and 90. That is, the holding portions 89 and 90 restrict the corresponding circuit boards 71 and 72 from moving outward in the longitudinal direction by the first movement restricting portion. Further, the holding portions 89 and 90 restrict the circuit boards 71 and 72 from moving to the side opposite to the board placement surface 59 by the second movement restricting portion. As a result, the end portions in the longitudinal direction of the corresponding circuit boards 71 and 72 are held by the holding portions 89 and 90.

また、本実施形態の収納装置１は、以下の付加的な特徴を有している。保持具８は、放熱部材５１の長手方向に離間して並んだ回路基板７１，７２の間に位置して、基板配置面５９に取り付けられた保持部材８１（第１の保持部材８１）を備える。保持部材８１の両側に配置された回路基板７１，７２のうちの一方の回路基板７１を一方回路基板７１とすると共に他方の回路基板７２を他方回路基板７２とする。保持部材８１は、保持部として、一方回路基板７１の他方回路基板７２側の端部を保持する一方保持部８９と、一方保持部８９と一体に形成され、他方回路基板７２の一方回路基板７１側の端部を保持する他方保持部９０とを備える。   The storage device 1 of the present embodiment has the following additional features. The holder 8 includes a holding member 81 (first holding member 81) that is positioned between the circuit boards 71 and 72 that are spaced apart in the longitudinal direction of the heat dissipation member 51 and attached to the board placement surface 59. . One of the circuit boards 71 and 72 disposed on both sides of the holding member 81 is referred to as one circuit board 71 and the other circuit board 72 is referred to as the other circuit board 72. The holding member 81 is formed integrally with the one holding unit 89 and the one holding unit 89 that holds the end of the one circuit board 71 on the other circuit board 72 side, and the one circuit board 71 of the other circuit board 72 as a holding unit. And the other holding portion 90 that holds the side end portion.

この特徴を有する収納装置１は、隣り合う回路基板７１，７２の間に設けられた保持部材８１の一方保持部８９と他方保持部９０とが一体に形成されるため、部品点数の増加が抑制され、容易に製造できる。   In the storage device 1 having this feature, since one holding portion 89 and the other holding portion 90 of the holding member 81 provided between the adjacent circuit boards 71 and 72 are integrally formed, an increase in the number of components is suppressed. And can be easily manufactured.

この特徴を有する収納装置１は、隣り合う回路基板７１，７２の間に設けられた保持部材８１が放熱部材５１に取り付けられるとき、当該保持部材８１が配線７４に接触しにくい。このため、作業者は、保持部材８１を放熱部材５１に容易に取り付けることができる。   In the storage device 1 having this feature, when the holding member 81 provided between the adjacent circuit boards 71 and 72 is attached to the heat dissipation member 51, the holding member 81 is unlikely to contact the wiring 74. For this reason, the operator can easily attach the holding member 81 to the heat radiating member 51.
