レール部材５２は、上下方向に長い略角筒状に形成され、下端には、左右方向に突出するように平板状の取付部５２ａが設けられる。チルト機構５０は、レール部材５２の取付部５２ａが筐体２０の下面２６を備える底板にビス止め等され固定される。レール部材５２の左右の側面（左側面５２ｂ３、右側面５２ｂ４）の前方側には、それぞれ、前板５２ｇと接続して取付部５２ａから立設するように上下方向に長い側板５２ｄが設けられる。左側面５２ｂ３、右側面５２ｂ４と後面５２ｂ２が交差する各角部には、それぞれ、取付部５２ａから立設するように上下方向に長い角柱状の柱状部５２ｃが設けられる。図３のＱ－Ｑ断面を示す囲み図にも示すように、レール部材５２における左側面５２ｂ３、右側面５２ｂ４には、側板５２ｄの後面５２ｄ１と柱状部５２ｃの前面５２ｃ１との間で形成される部分を第１ガイド部７１として設ける。第１ガイド部７１は、下端は取付部５２ａまで到達し、取付部５２ａの挿入口５２ａ１（後述）に接続する。 The rail member 52 is formed in the shape of a substantially square tube that is elongated in the vertical direction, and has a flat mounting portion 52a that protrudes in the horizontal direction at the lower end thereof. The tilt mechanism 50 is fixed to the bottom plate provided with the lower surface 26 of the housing 20 by screws or the like at the mounting portions 52 a of the rail members 52 . On the front sides of the left and right side surfaces (left side surface 52b3 and right side surface 52b4) of the rail member 52, vertically long side plates 52d are provided so as to connect to the front plate 52g and stand from the mounting portion 52a. At each corner where the left side surface 52b3, the right side surface 52b4, and the rear surface 52b2 intersect, a vertically elongated prism-shaped columnar portion 52c is provided so as to stand from the mounting portion 52a. As shown in the enclosing view showing the QQ section of FIG. 3, the left side 52b3 and the right side 52b4 of the rail member 52 are formed between the rear surface 52d1 of the side plate 52d and the front surface 52c1 of the columnar portion 52c. A portion is provided as a first guide portion 71 . The lower end of the first guide portion 71 reaches the attachment portion 52a and is connected to an insertion opening 52a1 (described later) of the attachment portion 52a.

柱状部５２ｃの上端は、角柱状の梁状部５２ｅを介して側板５２ｄの上端と接続する。また、図３のＱ－Ｑ断面を示す囲み図にも示すように、レール部材５２における後面５２ｂ２には、左右にある柱状部５２ｃにおいて、対向する一方の柱状部５２ｃの側面５２ｃ２と他方の柱状部５２ｃの側面５２ｃ２との間で形成される部分を第２ガイド部７２として設ける。このように、レール部材５２のガイド部７０（第１ガイド部７１と、第２ガイド部７２）を備える。また、左右の柱状部５２ｃの上端は、角柱状の接続部５２ｆで接続される。レール部材５２の上面５２ｂ５は、前面５２ｂ１を備える前板５２ｇと、梁状部５２ｅ及び接続部５２ｆで囲まれて、開口部５２ｈとして矩形に開口されている。レール部材５２の下面５２ｂ６（すなわち取付部５２ａの下面）は、略Ｔ字状の挿入口５２ａ１が開口し、レール部材５２の内部空間に連通する。より詳細には、左右の側板５２ｄの後面５２ｄ１の一部が挿入口５２ａ１まで延設される。また、挿入口５２ａ１の後側の内面（縁面）である後導入面５２ａ１１は、柱状部５２ｃの前面５２ｃ１と連続している。 The upper end of the columnar portion 52c is connected to the upper end of the side plate 52d via a prismatic beam portion 52e. Further, as shown in the enclosing view showing the QQ cross section of FIG. A portion formed between the portion 52c and the side surface 52c2 is provided as a second guide portion 72. As shown in FIG. Thus, the guide portion 70 (the first guide portion 71 and the second guide portion 72) of the rail member 52 is provided. Moreover, the upper ends of the left and right columnar portions 52c are connected by a prismatic connecting portion 52f.

The lower surface 52b6 of the rail member 52 (that is, the lower surface of the mounting portion 52a) has a substantially T-shaped insertion opening 52a1 that communicates with the internal space of the rail member 52 . More specifically, part of the rear surface 52d1 of the left and right side plates 52d extends to the insertion opening 52a1. A rear introduction surface 52a11, which is an inner surface (edge surface) on the rear side of the insertion port 52a1, is continuous with the front surface 52c1 of the columnar portion 52c.

図２（ａ）、図２（ｂ）に示すように、レール部材５２の前面５２ｂ１を備える前板５２ｇの後面側には、第１係合部６１が設けられる。図５（ａ）、図５（ｂ）に詳細に示すが、第１係合部６１は、側面視において三角状（直角二等辺三角）とされる凸部６１ａを上下方向に連続して複数配置させることにより、複数の凸部６１ａのうちの一の凸部６１ａと当該一の凸部６１ａに隣接する他の凸部６１ａによって形成される凹部６１ｂが、上下方向に連続して複数配置される。これにより、凸部６１ａと凹部６１ｂが上下方向に交互に配置される。第１係合部６１の三角状の各凸部６１ａは、下面６１ａ１をレール部材５２の前面５２ｂ１と直交させ、上面６１ａ２は前面５２ｂ１に対して傾斜する。 As shown in FIGS. 2A and 2B, a first engaging portion 61 is provided on the rear surface side of the front plate 52g including the front surface 52b1 of the rail member 52. As shown in FIG. As shown in detail in FIGS. 5(a) and 5(b), the first engaging portion 61 has a plurality of convex portions 61a each having a triangular shape (isosceles right triangle) in a side view continuously in the vertical direction. By arranging, a plurality of concave portions 61b formed by one convex portion 61a of the plurality of convex portions 61a and another convex portion 61a adjacent to the one convex portion 61a are continuously arranged in the vertical direction. be. Thereby, the convex portions 61a and the concave portions 61b are arranged alternately in the vertical direction. Each triangular convex portion 61a of the first engaging portion 61 has a lower surface 61a1 perpendicular to the front surface 52b1 of the rail member 52, and the upper surface 61a2 is inclined with respect to the front surface 52b1.

図３に戻り、スライド部材５３は、内部空間を有して前面及び下面が開放された略ブロック状に形成され、上板５３ａ、後板５３ｂ、前側の側板である前側板５３ｃ、後側の側板である後側板５３ｄを備える。前側板５３ｃ及び後側板５３ｄは、それぞれ、上板５３ａの左右端から下方に向けて延設される。後側板５３ｄが接続する上板５３ａの左右の幅は、前側板５３ｃが接続する上板５３ａの左右の幅よりも広く形成される。また、後板５３ｂは上板５３ａの後端から下方に向けて延設される。後板５３ｂの左右の幅は、前側板５３ｃが接続する上板５３ａの左右の幅と略同一である。対向する後側板５３ｄは、下方に向けて互いの間隔が広くなるように、正面側から見て逆Ｖ字状に傾斜して設けられる。後側板５３ｄは、左右方向に弾発力を有する。対向する前側板５３ｃは、前縁面の下端からそれぞれに向けて縦板状の規制突起５３ｃ１が設けられる。また、前側板５３ｃには、前後方向に長い長孔の貫通孔として形成される軸孔５３ｃ２が設けられる。図３のスライド部材５３をＰ方向から見た囲み図に示すように、後板５３ｂには、後板５３ｂの前面から突出するバネ支持軸５３ｂ１が設けられる。バネ支持軸５３ｂ１の周りには、略Ｕ字状のバネ受５３ｂ２が設けられる。後板５３ｂの後面における左右両端縁には、それぞれ下方に向けて漸次高さが高くなる傾斜リブ５３ｂ３が設けられる。 Returning to FIG. 3, the slide member 53 is formed in a substantially block shape having an inner space and an open front surface and a lower surface. A rear side plate 53d, which is a side plate, is provided. The front side plate 53c and the rear side plate 53d extend downward from the left and right ends of the upper plate 53a. The lateral width of the upper plate 53a to which the rear plate 53d connects is formed to be wider than the lateral width of the upper plate 53a to which the front plate 53c connects. The rear plate 53b extends downward from the rear end of the upper plate 53a. The lateral width of the rear plate 53b is substantially the same as the lateral width of the upper plate 53a to which the front plate 53c is connected. The rear side plates 53d facing each other are inclined in an inverted V shape when viewed from the front side so that the distance between them widens downward. The rear side plate 53d has elastic force in the left-right direction. The opposed front side plates 53c are provided with vertical plate-like restricting protrusions 53c1 directed from the lower ends of the front edge surfaces thereof. Further, the front side plate 53c is provided with a shaft hole 53c2 formed as an elongated through hole in the front-rear direction. As shown in the enclosed view of the slide member 53 viewed from the direction P in FIG. 3, the rear plate 53b is provided with a spring support shaft 53b1 protruding from the front surface of the rear plate 53b. A substantially U-shaped spring bearing 53b2 is provided around the spring support shaft 53b1. Inclined ribs 53b3 whose height gradually increases downward are provided on both left and right edges of the rear surface of the rear plate 53b.

スライド部材５３は、事前に脚部材５１及びコイルバネ５４をスライド部材５３にセットして、レール部材５２の挿入口５２ａ１から挿入して組付けることができる。このとき、挿入口５２ａ１で一時的にスライド部材５３の対向する後側板５３ｄが左右幅方向を縮小し、後側板５３ｄが第１ガイド部７１に位置したときに対向する後側板５３ｄの左右幅方向が復元される。なお、スライド部材５３の後側板５３ｄの前後方向の幅は、第１ガイド部７１の幅（柱状部５２ｃの前面５２ｃ１と側板５２ｄの後面５２ｄ１とで形成される部分の間）よりも若干小さい。そのため、第１ガイド部７１の内側にスライド部材５３の後側板５３ｄが配置される。具体的には、後側板５３ｄの左右方向の弾発力によって、第１ガイド部７１の内側にスライド部材５３の後側板５３ｄが入り込むようにして配置される。これにより、スライド部材５３はガイド部７０の第１ガイド部７１によって上下方向にガイドされる。同様に、スライド部材５３の後板５３ｂに設けられた２つの傾斜リブ５３ｂ３の外側面間で形成される幅は、第２ガイド部７２の幅（柱状部５２ｃの対向する側面５２ｃ２同士で形成される部分の間）よりも若干小さい。そのため、第２ガイド部７２の内側にスライド部材５３における後板５３ｂに設けられた２つの傾斜リブ５３ｂ３が配置される。これにより、スライド部材５３はガイド部７０の第２ガイド部７２によって上下方向にガイドされる。このようにして、スライド部材５３は、ガイド部７０により上下方向にガイドされる。 The slide member 53 can be assembled by setting the leg member 51 and the coil spring 54 on the slide member 53 in advance and inserting it through the insertion opening 52 a 1 of the rail member 52 . At this time, the opposing rear plate 53d of the slide member 53 temporarily contracts in the lateral width direction at the insertion opening 52a1, and when the rear plate 53d is positioned in the first guide portion 71, the opposing rear plate 53d in the lateral width direction is restored. The width of the rear side plate 53d of the slide member 53 in the front-rear direction is slightly smaller than the width of the first guide portion 71 (between the portion formed by the front surface 52c1 of the columnar portion 52c and the rear surface 52d1 of the side plate 52d). Therefore, the rear side plate 53 d of the slide member 53 is arranged inside the first guide portion 71 . Specifically, the rear plate 53d of the slide member 53 is arranged so as to enter the inner side of the first guide portion 71 due to the lateral repulsive force of the rear plate 53d. As a result, the slide member 53 is guided vertically by the first guide portion 71 of the guide portion 70 . Similarly, the width formed between the outer side surfaces of the two inclined ribs 53b3 provided on the rear plate 53b of the slide member 53 is the width of the second guide portion 72 (the width formed between the opposing side surfaces 52c2 of the columnar portion 52c). slightly smaller than Therefore, two inclined ribs 53 b 3 provided on the rear plate 53 b of the slide member 53 are arranged inside the second guide portion 72 . As a result, the slide member 53 is guided vertically by the second guide portion 72 of the guide portion 70 . In this manner, the slide member 53 is guided vertically by the guide portion 70 .

また、脚部材５１の揺動軸５１ｃはスライド部材５３の軸孔５３ｃ２に係合し、支持される（図５（ａ）、図５（ｂ）参照）。そして、脚部材５１のバネ支持軸５１ｄとスライド部材５３のバネ支持軸５３ｂ１間には、バネ支持軸５１ｄ，５３ｂ１を巻回するようにコイルバネ５４が設けられる（図４（ａ）、図４（ｂ）参照）。コイルバネ５４により、脚部材５１は、前方に付勢される。換言すれば、付勢手段であるコイルバネ５４により、脚部材５１は、第１係合部６１と第２係合部６２が凹凸係合６０として示す凹凸係合する係合方向に付勢される。一方、スライド部材５３の上方移動は、レール部材５２の梁状部５２ｅの下面がスライド部材５３の上板５３ａの上面と当接することで規制される。スライド部材５３の下方移動は、後側板５３ｄの下面及び後板５３ｂの傾斜リブ５３ｂ３の下面が取付部５２ａの上面と当接することで規制される。 Further, the pivot shaft 51c of the leg member 51 is engaged with and supported by the shaft hole 53c2 of the slide member 53 (see FIGS. 5(a) and 5(b)). A coil spring 54 is provided between the spring support shaft 51d of the leg member 51 and the spring support shaft 53b1 of the slide member 53 so as to wind the spring support shafts 51d and 53b1 (Fig. 4(a), Fig. 4( b) see). The leg member 51 is urged forward by the coil spring 54 . In other words, the leg member 51 is urged by the coil spring 54, which is the biasing means, in the engaging direction in which the first engaging portion 61 and the second engaging portion 62 are engaged with each other as shown as the concave-convex engagement 60. . On the other hand, the upward movement of the slide member 53 is restricted when the lower surface of the beam-shaped portion 52e of the rail member 52 contacts the upper surface of the upper plate 53a of the slide member 53. As shown in FIG. The downward movement of the slide member 53 is restricted by contact between the lower surface of the rear plate 53d and the lower surface of the inclined rib 53b3 of the rear plate 53b and the upper surface of the mounting portion 52a.

図４（ａ）の二点鎖線及び図５（ａ）に示す、脚部材５１の係合状態においては、脚部材５１がコイルバネ５４により前方に付勢されるため、脚部材５１の揺動軸５１ｃはスライド部材５３の軸孔５３ｃ２の前端に位置する。このとき、第２係合部６２は、第１係合部６１の凹部６１ｂに位置して、凹凸係合６０を構成する。この状態で投影装置１０を設置面ＤＴに設置し、脚部材５１の設置面当接部５１ａ１が設置面ＤＴからの反力を受けると、第２係合部６２の上面６２ａと、第１係合部６１の凸部６１ａの下面６１ａ１とが当接し、脚部材５１により投影装置１０（筐体２０）が支持される。 In the engaged state of the leg member 51 shown in FIG. 4(a) and FIG. 5(a), the leg member 51 is biased forward by the coil spring 54, so that the swing axis of the leg member 51 51 c is located at the front end of the shaft hole 53 c 2 of the slide member 53 . At this time, the second engaging portion 62 is positioned in the concave portion 61 b of the first engaging portion 61 to form the uneven engagement 60 . In this state, when the projection device 10 is installed on the installation surface DT and the installation surface contact portion 51a1 of the leg member 51 receives a reaction force from the installation surface DT, the upper surface 62a of the second engaging portion 62 and the first engaging portion 62 are brought into contact with each other. The projection device 10 (housing 20 ) is supported by the leg member 51 with the lower surface 61 a 1 of the projection 61 a of the joining portion 61 abutting thereon.

図４（ａ）の二点鎖線及び図５（ａ）に示す脚部材５１の係合状態から、当該係合状態を解除して、脚部材５１を上下方向に移動させるには、コイルバネ５４の付勢力に抗して脚部材５１の下端部を後方に押す。すると、図４（ｂ）の二点鎖線及び図５（ｂ）に示すように、脚部材５１は、揺動軸５１ｃ周りに後方側に向けて揺動すると共に、揺動軸５１ｃが軸孔５３ｃ２の後端まで移動する。すると、第２係合部６２は第１係合部６１の凹部６１ｂから脱し、第１係合部６１と第２係合部６２の係合状態が解除される。第１係合部６１と第２係合部６２の係合状態が解除された状態を維持して脚部材５１を上下方向に動かせば、脚部材５１は、レール部材５２（筐体２０）から出没させることができる。そして、脚部材５１の上下方向の可動範囲で脚部材５１から手を離せば、図４（ａ）の二点鎖線及び図５（ａ）に示す係合状態に復帰する。第１係合部６１の凸部６１ａ、凹部６１ｂ及び第２係合部６２は三角状に形成されるので、脚部材５１から手を離せば、傾斜して形成されて対向する第１係合部６１の凸部６１ａの上面６１ａ２及び第２係合部６２の下面６２ｂにより自動的に係合状態に復帰させることができる。 In order to release the engaged state of the leg member 51 shown in FIG. 4A and the leg member 51 shown in FIG. The lower end of the leg member 51 is pushed backward against the biasing force. Then, as shown in FIG. 4B and FIG. 5B, the leg member 51 swings rearward about the swing shaft 51c, and the swing shaft 51c moves toward the shaft hole. Move to the rear end of 53c2. Then, the second engaging portion 62 is released from the recess 61b of the first engaging portion 61, and the engaged state between the first engaging portion 61 and the second engaging portion 62 is released. If the leg member 51 is moved vertically while maintaining the disengaged state between the first engaging portion 61 and the second engaging portion 62, the leg member 51 is removed from the rail member 52 (housing 20). You can make it appear. Then, when the leg member 51 is released within the vertical movable range of the leg member 51, the engaged state shown in FIG. 4(a) and FIG. 5(a) is restored. Since the convex portion 61a, the concave portion 61b, and the second engaging portion 62 of the first engaging portion 61 are formed in a triangular shape, when the leg member 51 is released, the first engaging portion 61 which is inclined and opposed The upper surface 61a2 of the convex portion 61a of the portion 61 and the lower surface 62b of the second engaging portion 62 can automatically return to the engaged state.

このように、第１係合部６１及び前記第２係合部６２は、脚部材５１を後方に押圧する操作により凹凸係合が解除することができる。そして、脚部材５１は、筐体２０の下面２６からの突出量を調整されるので、投影装置１０の傾斜角度（投影角度）を調整することができる。なお、脚部材５１は、係合状態であっても脚部材５１を引っ張り出すことでレール部材５２から突出させることができる。この場合、傾斜する第１係合部６１の凸部６１ａの上面６１ａ２及び第２係合部６２の下面６２ｂが摺接し、第２係合部６２が順次凸部６１ａを乗り越える。 Thus, the first engaging portion 61 and the second engaging portion 62 can be released from the uneven engagement by the operation of pushing the leg member 51 rearward. Since the amount of protrusion of the leg member 51 from the bottom surface 26 of the housing 20 is adjusted, the inclination angle (projection angle) of the projection device 10 can be adjusted. The leg member 51 can be protruded from the rail member 52 by pulling out the leg member 51 even in the engaged state. In this case, the upper surface 61a2 of the convex portion 61a of the inclined first engaging portion 61 and the lower surface 62b of the second engaging portion 62 are in sliding contact, and the second engaging portion 62 sequentially climbs over the convex portion 61a.

（第２実施形態）
次に、図６（ａ）、図６（ｂ）及び図７（ａ）、図７（ｂ）に基づいて、本発明の第２実施形態を説明する。本実施形態に係るチルト機構５０Ａは、第１実施形態の脚部材５１に換えて、脚部材５１Ａの長さを延長するための補助部材５１０を設けた脚部材５１Ａを備えるものである。本実施形態のチルト機構５０Ａは、脚部材５１Ａ以外は第１実施形態のチルト機構５０（レール部材５２、スライド部材５３、コイルバネ５４）と構造を同じくするが、補助部材５１０を取り付けたため、本実施形態の脚部材５１Ａ、レール部材５２、スライド部材５３は、左右方向の幅寸法が大きく設定されている。なお、以下の説明では、第１実施形態と同じ個所や部材については同じ符号を付して、その説明は簡略化又は省略する。 (Second embodiment)

Moreover, the installation member 51a provided at the lower end of the leg member 51A is detachable. The configuration of the upper side of the leg member 51A (the second engaging portion 62, the swing shaft 51c, and the spring support shaft 51d) is the same as the leg member 51 of the first embodiment.

本実施形態の脚部材５１Ａも、第１実施形態の脚部材５１と同様にレール部材５２（筐体２０）から出没させることができる。図７（ａ）に示すように、脚部材５１Ａを突出することにより、補助部材５１０を凹部５２１に収納した状態でもチルト機構５０Ａを使用することができる。補助部材５１０を使用する場合には、脚部材５１Ａを突出させた後、設置部材５１ａを取り外し、補助部材５１０を軸部５１１周りに回動させる。このとき、脚部材５１Ａは、回動させる補助部材５１０とレール部材５２が干渉しない位置まで突出させておく。そして、回動させた補助部材５１０は、図７（ｂ）に示すように、保持部５２２に嵌め込んで係止して使用することができる。 51 A of leg members of this embodiment can also be made to appear and disappear from the rail member 52 (housing 20) like the leg member 51 of 1st Embodiment.

（第３実施形態）
次に、図８に基づいて、第３実施形態を説明する。第３実施形態に係るチルト機構５０Ｂは、第１実施形態に係るチルト機構５０の複数の凸部６１ａ、凹部６１ｂを有する第１係合部６１及び凸状の第２係合部６２（一の凸部）に換えて、凹凸係合の関係性を逆にした一の凸部６１０を有する第１係合部６１Ｂと複数の凸部６２１及びその間に形成される複数の凹部６２２を有する第２係合部６２Ｂとしたものである。その他の構成は、第１実施形態のチルト機構５０と同じである。従って、第１実施形態と同じ個所や部材については同じ符号を付して、その説明は簡略化又は省略する。なお、図８は、チルト機構５０Ｂを模式的に示している。 (Third embodiment)
Next, a third embodiment will be described based on FIG. The tilting mechanism 50B according to the third embodiment is similar to the tilting mechanism 50 according to the first embodiment, the first engaging portion 61 having the plurality of convex portions 61a and the concave portions 61b and the convex second engaging portion 62 (one The first engaging portion 61B has one convex portion 610 in which the relation of concave-convex engagement is reversed, and the second engaging portion 61B has a plurality of convex portions 621 and a plurality of concave portions 622 formed therebetween. This is the engaging portion 62B. Other configurations are the same as the tilt mechanism 50 of the first embodiment. Therefore, the same parts and members as those of the first embodiment are denoted by the same reference numerals, and the description thereof is simplified or omitted. Note that FIG. 8 schematically shows the tilt mechanism 50B.

本実施形態の脚部材５１Ｂも、第１実施形態の脚部材５１と同様に出没操作することができる。ここで、凸部６１０及び凸部６２１は、共に略四角柱状に形成される。第１係合部６１Ｂと第２係合部６２Ｂの係合状態では、第１係合部６１Ｂの凸部６１０が第２係合部６２Ｂの凹部６２２に凹凸係合し、凸部６１０の下面６１１と凸部６２１の上面６２１ａが当接する。チルト機構５０Ｂにおいても、脚部材５１Ｂの後方への揺動操作により、第１係合部６１Ｂと第２係合部６２Ｂの係合状態を解除することができる。なお、スライド部材５３は、第１実施形態と同様に、ガイド部７０（不図示）により上下方向にガイドされる。 The leg member 51B of the present embodiment can also be operated to appear and retract in the same manner as the leg member 51 of the first embodiment. Here, both the convex portion 610 and the convex portion 621 are formed in a substantially quadrangular prism shape. In the engaged state of the first engaging portion 61B and the second engaging portion 62B, the convex portion 610 of the first engaging portion 61B is engaged with the concave portion 622 of the second engaging portion 62B, and the lower surface of the convex portion 610 611 and the upper surface 621a of the convex portion 621 are in contact with each other. Also in the tilt mechanism 50B, the engagement state between the first engagement portion 61B and the second engagement portion 62B can be released by the rearward swinging operation of the leg member 51B. The slide member 53 is vertically guided by a guide portion 70 (not shown) as in the first embodiment.

第２係合部６２Ｂの複数の凹部６２２の深さは、揺動軸５１ｃ（揺動軸５１ｃの軸心である揺動支点）から離れるほど深くなるように形成されている。換言すれば、凸部６２１の高さは、揺動支点から離れるほど高くなるように形成されている。これにより、脚部材５１Ｂの上下位置に関わらず、第１係合部６１Ｂと第２係合部６２Ｂの凹凸係合６０が解除されるときの脚部材５１Ｂ（二点鎖線で示す脚部材５１Ｂ）の揺動角度が略同一となる。すなわち、第１係合部６１Ｂと第２係合部６２Ｂの凹凸係合が解除される位置は、何れの凸部６２１であっても、凡そ、二点鎖線で示す直線ＰＲ上の位置となる。従って、脚部材５１Ｂが上下方向のいずれの位置であっても、同じ操作感覚で脚部材５１Ｂの出没操作を行うことができる。例えば、脚部材５１Ｂの没入状態で第１係合部６１Ｂと第２係合部６２Ｂの係合を解除して、そのときの脚部材５１Ｂの揺動角度を維持したまま脚部材５１Ｂを突出させることができる。 The depths of the plurality of recesses 622 of the second engaging portion 62B are formed so as to become deeper the farther from the swing shaft 51c (the swing fulcrum that is the axis of the swing shaft 51c). In other words, the height of the convex portion 621 is formed so as to increase with increasing distance from the swing fulcrum. As a result, regardless of the vertical position of the leg member 51B, the leg member 51B when the uneven engagement 60 between the first engaging portion 61B and the second engaging portion 62B is released (the leg member 51B indicated by the two-dot chain line). are substantially the same. That is, the position at which the concave-convex engagement between the first engaging portion 61B and the second engaging portion 62B is released is approximately on the straight line PR indicated by the two-dot chain line, regardless of the convex portion 621. . Therefore, regardless of the position of the leg member 51B in the vertical direction, the retracting operation of the leg member 51B can be performed with the same operational feeling. For example, when the leg member 51B is retracted, the engagement between the first engaging portion 61B and the second engaging portion 62B is released, and the leg member 51B is protruded while maintaining the swinging angle of the leg member 51B at that time. be able to.

以上、本発明の実施形態を説明したが、本発明は本実施形態にかかわらず、種々変更して実施することができる。例えば、第１係合部６１，６１Ｂ及び第２係合部６２，６２Ｂの凹凸係合６０は、図９に示すように、種々の形状を採用することができる。凹凸係合６０ａは、側面視二等辺三角形状であり、凹凸係合６０ｂは側面視円弧状、凹凸係合６０ｃは側面視台形状、凹凸係合６０ｄは側面視長矩形状である。 Although the embodiments of the present invention have been described above, the present invention can be implemented with various modifications regardless of the embodiments. For example, the concave-convex engagement 60 of the first engaging portions 61, 61B and the second engaging portions 62, 62B can adopt various shapes as shown in FIG. The concave-convex engagement 60a has an isosceles triangle shape when viewed from the side, the concave-convex engagement 60b has an arc shape when viewed from the side, the concave-convex engagement 60c has a trapezoidal shape when viewed from the side, and the concave-convex engagement 60d has a long rectangular shape when viewed from the side.

また、レール部材５２のガイド部７０や第１係合部６１は、筐体２０の内部に直接、すなわち、筐体２０と一体的に設けておいてもよい。また、脚部材５１を移動させる際の操作は、後方への揺動操作としたが、前方等の他の方向の揺動操作としてもよい。 Further, the guide portion 70 and the first engaging portion 61 of the rail member 52 may be provided directly inside the housing 20 , that is, integrally with the housing 20 . Further, the operation for moving the leg member 51 is a rearward swinging operation, but it may be a frontward swinging operation.

Various urging means such as an elastic member such as rubber can be used instead of the coil spring 54 . As a result, the leg members 51, 51A, 51B can be swung to release the uneven engagement 60, and the uneven engagement 60 can be automatically restored only by releasing the hand.

また、スライド部材５３及び脚部材５１，５１Ａ，５１Ｂは、一方であるスライド部材５３に長孔としての軸孔５３ｃ２を備えて他方である脚部材５１，５１Ａ，５１Ｂに軸孔５３ｃ２と係合する揺動軸５１ｃを備えることにより脚部材５１，５１Ａ，５１Ｂがスライド部材５３に揺動自在に設けられる。これにより、脚部材５１，５１Ａ，５１Ｂの揺動角度を大きくしたり、凸部６１ａの間隔（すなわち凹部６１ｂの大きさ）を大きくしたりしなくても、凹凸係合を解除することができ、適切な操作感を得ることができる。なお、スライド部材５３に揺動軸を設け、脚部材５１，５１Ａ，５１Ｂに長孔を設けてもよい。 Further, the slide member 53 and the leg members 51, 51A, 51B are provided with a shaft hole 53c2 as an elongated hole in the slide member 53, and engage with the shaft hole 53c2 in the other leg members 51, 51A, 51B. The leg members 51, 51A, and 51B are provided on the slide member 53 so as to be swingable by providing the swing shaft 51c. As a result, the uneven engagement can be released without increasing the swing angle of the leg members 51, 51A, 51B or increasing the interval between the protrusions 61a (that is, the size of the recesses 61b). , you can get an appropriate feeling of operation. The slide member 53 may be provided with a pivot shaft, and the leg members 51, 51A and 51B may be provided with elongated holes.

また、第１係合部６１は、凸部６１ａを上下方向に連続して複数配置させることにより、複数の凸部６１ａのうちの一の凸部６１ａと当該一の凸部６１ａに隣接する他の凸部６１ａによって形成される凹部６１ｂが、上下方向に連続して複数配置され、第２係合部６２は、一の凸部が配置される。これにより、多段階で脚部材５１，５１Ａを筐体２０から突出させることができるので、投影装置１０を設置する環境に応じて投影角度を調整することができる。 In addition, the first engaging portion 61 has a plurality of convex portions 61a continuously arranged in the vertical direction, so that one convex portion 61a of the plurality of convex portions 61a and another convex portion 61a adjacent to the one convex portion 61a are arranged.
