To enable upward/downward motion of a tray member with a simple structure.SOLUTION: A holder device includes: a tray member on which an object is placed and which may move up or down; a first guide member which may rotate around a rotation axis relative to the tray member; a second guide member which guides the tray member in a liftable manner; and a conversion mechanism which converts relative rotational motion between the tray member and the first guide member into upward/downward motion of the tray member. The conversion mechanism has: guide projection parts which are provided at the tray member and project in a radial direction centered on the rotation axis; first guide groove parts which are provided on a side wall of the first guide member so as to extend spirally around the rotation axis and respectively engaged with the guide projection parts; and second guide groove parts which are provided on a side wall of the second guide member so as to extend in a vertical direction and respectively engaged with the guide projection parts.SELECTED DRAWING: Figure 3
【課題】トレイ部材の昇降動作を簡易な構造で実現すること。【解決手段】ホルダ装置は、対象物が載置される昇降可能なトレイ部材と、回動軸を中心にしてトレイ部材に対して相対的に回動可能な第一ガイド部材と、トレイ部材を昇降可能に案内する第二ガイド部材と、トレイ部材と第一ガイド部材との相対的な回動動作をトレイ部材の昇降動作へ変換する変換機構と、を備える。変換機構は、トレイ部材に設けられ、回動軸を中心にした径方向へ突出するガイド突起部と、第一ガイド部材の側壁に回動軸を中心にして螺旋状に延びるように設けられ、ガイド突起部が係合する第一ガイド溝部と、第二ガイド部材の側壁に上下方向に延びるように設けられ、ガイド突起部が係合する第二ガイド溝部と、を有する。【選択図】図3
