Abstract: To provide a hand stocker with a simple structure. A hand stocker housing a hand for attaching on an actuator includes a housing board that houses the hand in a hung state and includes a hanging mechanism hanging the hand on a board surface facing the hand. The hanging mechanism includes: a hooking member that extends in a horizontal direction from the board surface to engage with a hanging portion disposed in the hand; a pressing member that prevents the hand hung on the hooking member from moving to a direction separating from the board surface; and a supporting member that restricts the hand hung on the hooking member from moving to a direction approaching the board surface. The hand is sandwiched between the pressing member and the supporting member and housed.

Abstract: An air blowing device is numerically controllable. An air blowing device includes a feed base, a nozzle base arranged at a distal end of the feed base, a spindle housing arranged in the nozzle base, a spindle rotatable about a rotation axis, a nozzle block including a first nozzle, and a first fluid channel for feeding dry air to the first nozzle and including a first main pipe, a first annular channel, a first connecting tube, and a first communication channel communicating with the first annular channel and the first nozzle.
