PROBLEM TO BE SOLVED: To provide a telescopic type drive guide device that can suppress a drive load from becoming excessive from the beginning at the time of extending a guide mechanism with an extendable telescopic structure from the most contracted condition.SOLUTION: The telescopic type drive guide device comprises a switch mechanism that can switch an operation condition between a regulating condition that regulates relative movement of guide members 21-24 adjacent in an extending direction of a guide mechanism 14 having a telescopic structure and a permitting condition that permits the relative movement. The switch mechanism switches the operation condition thereof so that when extending the guide mechanism from the most contracted condition, at first only a movable guide member 24, of a plurality of movable guide members 24, 23 and 22, which extends most in the extending direction is moved toward an extended side and thereafter movable guide members to be moved toward the extended side increase one by one in the order from the most extended movable guide member toward the most contracted movable guide member 22.

    【課題】伸縮可能なテレスコピック構造のガイド機構を最収縮状態から伸長させる際の駆動負荷が最初から過大となることを抑制できるテレスコピック式駆動ガイド装置を提供する。【解決手段】テレスコピック式駆動ガイド装置は、テレスコピック構造をなすガイド機構14の伸縮方向で隣り合うガイド部材21〜24同士の相対移動を規制する規制状態と許容する許容状態とに動作状態を切り替え可能な切替機構を備える。そして、その切替機構は、ガイド機構を最収縮状態から伸長させるとき、最初は複数の可動ガイド部材24,23,22のうち伸縮方向で最伸長側の可動ガイド部材24だけが伸長側に移動し、その後は伸長側に移動する可動ガイド部材が最伸長側の可動ガイド部材から最収縮側の可動ガイド部材22に向かう順番で一つずつ増えるように、その動作状態を切り替える。【選択図】図2
