Paper-feeding apparatus and method of feeding paper

A paper-feeding apparatus is used for feeding print medium from a paper cassette. The paper cassette holds a stack of print paper therein. The feeding roller is disposed close to a forward end of the paper cassette. The feeding roller engages a top page of the stack of print paper to feed the top page from the paper cassette to a printing area. The paper separator engages the feeding roller to cooperate with the feeding roller to separate the top page from the stack of print paper. The paper-positioning member is, for example, an arm. When the feeding roller is not feeding the print medium, the arm pushes back the forward ends of pages of print medium toward the rear end of the paper cassette, thereby aligning the forward ends of the pages of the stack of print paper. The paper feeding apparatus may further have an urging member, e.g., a spring, which urges the paper separator against the feeding roller, and an urging-force-changing member, e.g., a cam that changes an urging force of the urging member. When the cam rotates to a high-pressure position, the cam pushes the spring to cause the spring to urge the medium separator against the feeding roller with a larger force. When the cam rotates to a low-pressure position, the cam pushes the spring to cause the spring to urge the medium separator against the feeding roller with a smaller force.

Vacuum based pill singulator and counter based thereon

A singulating disc, carried by a housing, has a plurality of openings around its periphery. The disc rotates vertically through a pickup chamber of a hopper carried by the housing. A vacuum is pulled through the openings by a pump which is connected to the disc. Items are placed in the hopper and, via gravity, fall to the bottom of the hopper where they contact the periphery of the rotating disc. The vacuum at the openings attaches an item and holds it while the disc rotates. At the top of the disc's rotation, a diverter directs the item into a path depending on the results of a fragment detection and/or counting mechanism. Items that are allowed to pass by the diverter are scraped off the disc into another path by a scraper. Negative pressure is used to singulate and count a multitude of sizes and shapes of items with no calibration. Retractable paddles, a vacuum management system, and RFID tags may be incorporated. The paddles aid in the pickup and agitation of the items while the vacuum management system conserves the vacuum capacity necessary to pickup and singulate items. The RFID tags may contain information such as the number of items left in the hopper, a par level for that item, an expiration date, among others. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
