Abstract
A feeding unit for feeding media of varying thickness includes a plurality of rolling members defining a media feeding port therebetween, at least one pressing arm located on one of the rolling members, at least one elastic member, and a switch member. The pressing arm has a main body, a first pressing end formed on one end of the main body and a second pressing end formed on the other end of the main body, and the main body has a fulcrum thereon. The first pressing end is selectively connected onto said one of the rolling members. One end of the elastic member abuts against the first pressing end. The switch member is slidable to selectively press the second pressing end.
Claims20
A feeding unit for feeding media of varying thickness, the feeding unit being disposed inside a casing, the feeding unit comprising:
- a plurality of rolling members defining a media feeding port therebetween;
- at least one pressing arm located on one of the rolling members, the pressing arm having a main body, a first pressing end formed on one end of the main body and a second pressing end formed on the other end of the main body, the first pressing end selectively connected onto said one of the rolling members, the main body having a fulcrum thereon;
- at least one elastic member, one end of the elastic member abutting against the first pressing end, the other end of the elastic member fixedly connected to the interior of the casing;
- and
- a switch member selectively forcing on the second pressing end;
- wherein when the second pressing end is released from the switch member, the first pressing end forces on the corresponding rolling member due to the force of the elastic member so that media of a first thickness is fed through the media feeding port;
- and
- wherein when the second pressing end is forced by the switch member, the first pressing end is pivoted away from the corresponding rolling member and simultaneously compresses the elastic member to form a gap between the first pressing end and the corresponding rolling member so that media of a second thickness is fed through the media feeding port.
A media processing apparatus for media of varying thickness comprising:
- a casing having a media entrance;
- and
- a feeding unit assembled with the casing, the feeding unit including:
- a plurality of rolling members defining a media feeding port corresponding to the media entrance;
- at least one pressing arm located on one of the rolling members, the pressing arm having a main body, a first pressing end formed on one end of the main body and a second pressing end formed on the other end of the main body, the first pressing end selectively connected onto said one of the rolling members, the main body having a fulcrum thereon;
- at least one elastic member, one end of the elastic member abutting against the first pressing end, the other end of the elastic member fixedly connected to the interior of the casing;
- and
- a switch member assembled with the casing and selectively forcing on the second pressing end;
- wherein when the second pressing end is released from the switch member, the first pressing end forces on the corresponding rolling member due to the force of the elastic member so that media of a first thickness is fed through the media feeding port;
- and
- wherein when the second pressing end is forced by the switch member, the first pressing end is pivoted away from the corresponding rolling member and simultaneously compresses the elastic member to form a gap between the first pressing end and the corresponding rolling member so that media of a second thickness is fed through the media feeding port.
