However, the tape feeder cannot be stably placed on the horizontal surface of the rack side by using the surface 7a.

An object of the present invention is to provide a storage rack for an electronic component tape feeder that can stably store a tape feeder whose center of gravity is close to a corner.

[Means for Solving the Problems]

The storage rack of the tape feeder for electronic parts according to the present invention comprises a reel arm, a cartridge wound around a reel at one end of the reel arm, and a fixing base having a fixing pin at the other end. And a storage rack for storing a plurality of the tape feeders, wherein the storage rack includes a back plate, a partition plate, a support rod, and a movement prevention hook with a locking hole, A partition plate is fixed to the back plate, and a plurality of sheets are provided in the horizontal direction at intervals that maintain a gap in the thickness of the tape feeder, and the supporting rods are orthogonal to each other between the partition plates, and the reels of the accommodated tape feeder And a corner portion of the reel arm, and at least a part of the movement prevention hook is formed of a spring so that the movement prevention hook can expand and contract in the direction of the support rod, and the locking hole portion serves to fix the fixing base. It is intended to pull the opposite direction of the supporting rod the locking hole engages the fixed pin with obtaining.

[Action]

Hook the fixing pin provided on the fixing base at the other end of the tape feeder into the locking hole provided in the movement prevention hook of the storage rack, and pull the entire tape feeder lightly while applying the corner to the support bar to move. The spring force of the prevention hook pulls the fixing pin in the opposite direction of the support rod, and a frictional force due to the spring is generated between the fixing pin and the locking hole, so that the tape feeder is elastically held in the storage rack. Even if the distance between the center of the reel and the fixed pin changes or the diameter of the reel changes and the distance L ₁ between the corner and the fixed pin changes slightly, the movement prevention hook responds by expanding and contracting L ₀ with a spring.
