Abstract
Abstract In the apparatus for separating test strips, a supply container (1) for the test strips (13) is provided with an orifice (14). Arranged in this orifice (14) is a transport device (12) which is equipped with a guide plate (7) and with drivers (3) and which has noses (10, 19). The noses (10, 19) interact with a moveably arranged bar (11) which projects into the orifice of the container.

Claim 1
Independent Claim
227 words
An apparatus for separating test strips, comprising: a supply container for receiving a plurality of test strips randomly disposed therein, said supply container having an exit orifice; a transport device, closely associated with said exit orifice, for separately transferring said test strips from said exit orifice to a guide chute, said transport device including a rotatably mounted roller plate and at least one hook-shaped driver extending from the periphery thereof, said hook-shaped driver defining a slot for receiving one of said test strips therein and for carrying said test strip from said exit orifice to said guide chute; a pivotable bar, having a free end extending into said exit orifice, for selectively feeding said test strips into said exit orifice and for preventing blocking of said exit orifice; said at least one hook-shaped driver of said roller plate having a nose portion configured to engage said bar as said roller plate is rotated to pivotably move said free end of said bar; pawl means, pivotably mounted adjacent to said roller plate, for moving said test strip received in said slot of said driver toward said guide chute, and at least one bolt-like projection, extending from said roller plate, for pivoting said pawl means as said roller plate is rotated; and return means, operably connected to said pawl means, for biasing said pawl means toward an initial position.
