Title (EN) IMAGE DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE D'IMAGE
(JA) 画像表示装置
Abstract:
(EN) This image display device (2) is provided with a liquid crystal cell (22), a flat plate-shaped lower frame (12), a lower frame (12), a light guide plate (36), and a pair of support mechanism parts (120). The pair of support mechanism parts (120) are fixed to the lower frame (12) and disposed at positions sandwiching the light guide plate (36) from both sides in a first direction (an X-axis direction). Each of the pair of support mechanism parts (120) has: a movable section (123) that supports the light guide plate (36); a main body section (121) that movably holds the movable section (123); and an elastic member (126) that biases the movable section (123) toward the other support mechanism part (120). The movable section (123) is provided with a protruding portion (124) and the light guide plate (36) is provided with an engagement portion (130) engaging with the protruding portion (124). The engagement portion (130) has: a tap (132) formed in an outward direction from an end surface of the light guide plate (36); and a groove (131) that is formed in the tap (132) and engages with the protruding portion (124).
(FR) Selon la présente invention, ce dispositif d'affichage d'image (2) est pourvu d'une cellule à cristaux liquides (22), d'un cadre inférieur en forme de plaque plate (12), d'un cadre inférieur (12), d'une plaque de guidage de lumière (36), et d'une paire de parties de mécanisme de support (120). La paire de parties de mécanisme de support (120) sont fixées au cadre inférieur (12) et disposées à des positions prenant en sandwich la plaque de guidage de lumière (36) des deux côtés dans une première direction (direction d'axe X). Chacune de la paire de parties de mécanisme de support (120) comprend : une section mobile (123) qui soutient la plaque de guidage de lumière (36) ; une section de corps principal (121) qui maintient de façon mobile la section mobile (123) ; et un élément élastique (126) qui sollicite la section mobile (123) vers l'autre partie de mécanisme de support (120). La section mobile (123) est pourvue d'une partie en saillie (124) et la plaque de guidage de lumière (36) est pourvue d'une partie de mise en prise (130) venant en prise avec la partie en saillie (124). La partie de mise en prise (130) comprend : une prise (132) formée dans une direction vers l'extérieur à partir d'une surface d'extrémité de la plaque de guidage de lumière (36) ; et une rainure (131) qui est formée dans la prise (132) et vient en prise avec la partie en saillie (124).
(JA) 画像表示装置(2)は、液晶セル(22)と、平板状の下フレーム(12)と、下フレーム(12)と、導光板(36)と、一対の支持機構部(120)とを備える。一対の支持機構部(120)は、下フレーム(12)に固定され、導光板(36)を、第一方向(X軸方向)の両側から挟む位置に配置されている。一対の支持機構部(120)のそれぞれは、導光板36を支持する可動部(123)と、可動部(123)を移動可能に保持する本体部(121)と、可動部(123)を他方の支持機構部(120)の方向に付勢する弾性部材(126)とを有する。可動部(123)には、突出部(124)が設けられており、導光板(36)には突出部(124)が係合する係合部(130)が設けられている。係合部(130)は、導光板(36)の端面から外向きに形成されたタブ(132)と、タブ(132)に形成され、突出部(124)に係合する溝(131)とを有する。
