[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage pack for electronic parts, and more particularly to an electronic part which can be used both as a packing means for storing chip-type electronic parts and as a supply means for individually sending out electronic parts when the electronic parts are mounted. It relates to a parts storage pack.

2. Description of the Related Art Conventional storage packs for electronic components include:
For example, there is one disclosed in Japanese Utility Model Laid-Open Publication No. 2-111682. FIG. 12 is a front view of a conventional electronic component storage pack described in the publication, and FIG. 13 is a partially enlarged front view of a shutter mechanism of the conventional storage pack. As shown in these drawings, the conventional electronic component storage pack is configured by providing a spirally provided electronic component storage path 102 for aligning and storing a plurality of chip-type electronic components inside a flat case body 101. Is done. At least the innermost peripheral end 102a of the storage path 102 is provided on the plate surface of the case main body with an air inflow hole 103 that communicates with the outside of the case and sends the compressed air of the electronic component, and the outermost peripheral end 102n of the storage path 102. An electronic component outlet 105 is provided to feed the electronic components one by one to the outside of the case one after another in a straight line from the electronic component. Further, a shutter 106 that opens and closes in synchronization with the feeding of the compressed air is provided at the opening of the sending port 105. Therefore, if the shutter 106 is operated at the same time as the compressed air is fed into the storage path, the electronic components can be taken out of the case one by one from the outlet 105. The shutter 106 is the outlet 1
One end has a hook 106a protruding into the opening of the support plate 105, and the middle abdomen of which is supported on the support plate 101a by the support pin 106b.
And the other end is rotatably supported by a spring 106c interposed between the support plate 101a and the other end.

[0003]

A problem with the prior art is that it is not possible to reliably separate and send out the electronic components one by one from the outlet.

[0004] The reasons for this are that the timing of a shutter that opens and closes in synchronism with the pressure-feed air is shifted, the air pressure is excessive or insufficient,
Alternatively, the electronic components may not be ejected one by one due to clogging of the electronic components due to the catch of the shutter or excessive transmission.
