Abstract
Abstract Magazine for storing and supplying chip type circuit elements includes a tube having a bore formed therethrough in which the circuit elements are situated in stacked relationship for feeding toward an open supply end and wherein an elastic member is provided on the tube in the region of the supply end having a surface facing inwardly into the bore and wherein a keeper pawl extends inwardly from the free end of the elastic member into the bore at the supply end region, preferably slightly below the supply end, adapted to hold the leading circuit element under pressure prior to the same being supplied in one-by-one fashion and to prevent simultaneous supply of more than one circuit element from the supply end of the magazine and, additionally, to precisely locate each circuit element at the supply end. In one embodiment, longitudinally extending ribs protruding inwardly into the bore are formed on the bore defining surface of the tube which maintain the chip elements in precise mutual alignment.

Claim 1
Independent Claim
239 words
In a magazine for storing and supplying circuit elements having a tube which stores the plurality of circuit elements in a stacked state within a bore thereof, the tube having an open upper discharge end, the bore being adapted to receive a plug member so as to be movably disposed within the bore for supporting the stacked circuit elements, the improvement comprising: an elastic member provided at one side of a region of the upper discharge end of said tube, said elastic member having a free end, and a keeper pawl formed at the free end of said elastic member extending inwardly into the bore for holding under pressure a leading one of the circuit elements within said bore, said keeper pawl having a free end which is located lower than the discharge end of said tube; said bore being defined by inner surfaces of said tube, at least one of said inner surfaces having at least one inwardly protruding rib which extends continuously in a longitudinal direction; and a plug member including a platform portion adapted to support the circuit elements from below in a stacked state and engaging portions integral with said platform portion, said engaging portions elastically engaging the inner surfaces of said tube so that said plug member is prevented from falling within said tube under its own weight; whereby the circuit elements can be discharged from the upper discharge end in an axial direction.

Claim 3
Dependent Claim
39 words
A magazine for storing and supplying circuit elements as defined in claim 1 wherein said keeper pawl is partially defined by a surface which extends inwardly into said bore in a direction towards the supply end of said tube.
Claim 4
Dependent Claim
34 words
A magazine for storing and supplying circuit elements as defined in claim 1 wherein a pair of said ribs are formed on each of a pair of opposed bore defining surfaces of the tube.
Claim 5
Dependent Claim
35 words
A magazine for storing and supplying circuit elements as recited in claim 1 wherein said engaging portions are formed with at least one guide groove which receive corresponding ones of said ribs in said tube.
Claim 6
Dependent Claim
59 words
A magazine for storing and supplying circuit elements as recited in claim 1 wherein said bore has a rectangular cross-section defined by two opposed pairs of inner surfaces, and wherein said elastic member has an inner surface which forms one of the four inner surfaces defining said bore at the region of the upper supply end of the tube.
