Abstract: A guide wire includes a core shaft including a distal end portion that is curved in a predetermined direction, a coil body covering the outer periphery of the core shaft, and a distal tip joining a distal end portion of the core shaft and a distal end portion of the coil body. The distal tip has a convex shape oriented toward a distal end side. In a cross section of the core shaft cut along a plane including the central axis, the distal tip includes a curve inner portion located on an inside of the curve of the distal end portion relative to the central axis of the core shaft and a curve outer portion located on an outside of the curve of the distal end portion relative to the central axis. A cross-sectional area of the curve inner portion is smaller than that of the curve outer portion.

Abstract: The present assistance in picking system assists in a putting-in operation to put an article, about which instructions have been issued, in storage sections on storage racks and a picking operation to pick articles, about which instructions have been issued, from the storage section. The system assigns positions of storage sections on the storage racks, stores assigned positional information of the storage sections, and stores article information of the articles to be stored in the storage sections in a storage device. The system outputs to a putting-in display response device information of articles that have been put in, information which is read from the storage device, and outputs to a picking display response device information of articles that have been picked, including articles that have yet to be picked, as well as the numbers thereof, thereby performing picking control.

Abstract: A drawer unit of storage racks comprises a base frame and roller conveyer portions attached to both sides of the base frame and in which a plurality of rollers are arranged rotatably in parallel on each conveyer frame so that an article storage tray is movable in a back and forth direction. A drawer slider on which an article storage tray is to be placed is disposed movably in a back and forth direction of the base frame, and an actuator for driving the drawer slider in a back and forth direction is provided on the base frame. In this drawer unit, an article storage tray for storing articles is placed on the drawer slider and when an instruction for picking out is issued, the drawer slider is moved in a forward direction by an operation of the actuator in such a way that the article storage tray is pulled out of a storage section of the racks in a forward direction.
