DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention is mainly used as a means for packing and transporting electronic components having a chip type, and also supplies a plurality of electronic components housed inside to an automatic mounting machine. The present invention relates to a storage case for electronic components used as means.

Conventional technology Conventionally, as a storage case for this type of electronic component,
Case board part 1a fitted and fixed to each other as shown in the figure
The case main body 1 is formed in a disk shape from the case cover plate 1b and the case main body 1 is made of a transparent plastic material as shown in FIG. -Shaped storage path 2 for electronic parts, and electronic parts provided on the end face of the case body 1 so as to be continuous with the storage path 2 from the spiral line 2n located at the outermost periphery of the storage path 2 through the straight path 2p And an air feed hole 4 provided so as to communicate with the inner surface of the groove of the storage passage 2 from the outer surface of the case substrate portion 1a, as shown in FIG.
Proposed is one in which a plurality of electronic components housed in the storage path 2 are pneumatically fed toward the outlet 3 after being aligned by a plurality of pressure-fed air intermittently blown from the air supply hole 4 into the storage path 2. It has been done (No. 2-37892, Kaikaidaira).

In this storage case for electronic components, not only can a plurality of electronic components be aligned and stored in the storage passage 2, but also the electronic components can be taken out along the storage passage 2 only by intermittently sending compressed air to the storage passage 2. It is possible to move pneumatically up to 3.

More specifically, the case for storing the electronic parts will be described in detail. In order to gradually move the electronic parts toward the outlet 3, a plurality of air supply holes 4 are provided corresponding to the spiral lines 2a to 2n of the storage path 2a. ~
By providing 4n and arranging the air feed holes 4a to 4n in line, it is possible to form the feed air simultaneously from the coupling as described later. Further, a plurality of other air feeding holes 5a to 5n are arranged at intervals from the above-described air feeding holes 4a to 4n, and the air feeding holes 4a to 4n and 5a to 5n are arranged in relative directions. The compressed air is blown into and the electronic parts are rotated clockwise in every half of the case body 1,
If it moves counterclockwise, the electronic components are individually ejected from the tops of the spiral strips 2a to 2n by gradually swinging toward the opening side of the ejection port 3 and sliding down from the tops by their own weight.
It can be moved stably toward.

Problems to be Solved by the Invention By the way, the above-mentioned air feeding holes 4 to 5 are inclined obliquely because it is necessary to feed the compressed air in the forward direction with respect to the feeding direction X of the electronic component as shown in FIG. It is preferable to make it slanted and to form it in a slit-like shape so that the air pressure acts vigorously on the electronic component. Further, in order to form the air feeding holes 4 to 5, it is possible to provide the case substrate portion 1a by post-processing after forming the case substrate portion 1a. At the time of die-cast molding, it is preferable that the air feeding holes 4 to 5 are simultaneously molded.

However, a plurality of extremely fine protruding pins having the same size as the air feeding holes 4 to 5 must be provided upright on the mold surface in the molding die forming the storage case, and as described above, the air feeding holes must be provided. When the insertion holes 4 and 5 are formed to be inclined relative to each other, it is necessary to provide a plurality of projecting pins on the mold surfaces facing each other, so that the mold for forming the case substrate portion 1a becomes extremely complicated. In addition, if the protruding pin is formed so as to stand up diagonally, when the case substrate 1a is removed from the mold, the case substrate 1a has to be relatively obliquely displaced from the molding die and then separated. It is easy for the protruding pin to be lost due to this.

In view of the above, the present invention has an object to provide a storage case for electronic parts in which the structure of the air supply hole is improved so as to form the air supply hole with a simple mold structure.

Means for Solving the Problems In an electronic component storage case according to the present invention, an outwardly widening-shaped punched hole having a slope serving as a rear wall of an air inlet hole that is inclined forward with respect to the electronic component feeding direction. Is provided in the case body, and is fitted into the case from the wide side of the hole to fix the plate-like piece having the slope that becomes the front wall of the air supply hole, and the slopes that become the rear wall and the front wall. It is configured by providing air feed holes at relative positions with a gap provided therebetween. Further, the air introduction hole may be formed by a curved hole formed in a round shape facing the inner surface of the groove of the storage path and each inclined surface of the plate-shaped piece.

Action In this electronic component storage case, an outward expansion hole is provided in the case body, and a plate-like piece is fitted and fixed inside from the wide side of the hole to provide an air feed hole. It can be formed by using a mold having a simple structure. Further, since the air inlet hole is formed by locating the slope provided in the vent hole and the slope provided in the plate-like piece relative to each other, it can be easily formed in a slit shape. It is also possible to form the compressed air by sending the compressed air to the direction of sending the electronic component extremely efficiently by forming the rounded shape.
