Media pick system and media pick method thereof
View Patent ↗A media pick system includes a pick-up rack, a pick-up roller, a separate roller, a swing gear arm, a swing gear lever, and a part of action. While the separate roller and the swing gear arm are driven to rotate, the swing gear lever would be driven to rotate. Therefore, while the torque generated on the pick-up rack by the part of action so that the pick-up rack could be lifted up or pushed down to pick up the media.
1. A media pick system comprising:
a pick-up rack swinging between a pick-up position and a non-pick-up position and having a first feed roller and a second feed roller;
a swing gear arm linked to the second feed roller and having a swing gear arranged thereon; and
a swing gear lever having an end connected to the swing gear arm and an another end connected to a part of action, wherein the swing gear arm includes a protrusion, the swing gear lever includes an arc slot, the protrusion movably engages with the arc slot;
whereby the second feed roller and the swing gear arm rotate toward a first direction, the swing gear of the swing gear arm engages with a gear portion so as to drive the swing gear lever to actuate the part of action while the swing gear lever rotates toward the first direction; the part of action forces the pick-up rack to swing to the pick-up position, so that the first feed roller contacts paper;
the second feed roller and the swing gear arm rotate toward a second direction, the swing gear of the swing gear arm engages with the gear portion so as to drive the swing gear lever to restore the part of action while the swing gear lever rotates toward the second direction; the part of action forces the pick-up rack to swing to the non-pick-up position, so that the first feed roller goes away from the paper.
2. The media pick system according to claim 1 , wherein the arc slot defines a first end and a second end; when the swing gear of the swing gear arm engages with the gear portion along the first direction, the protrusion moves toward and forces the second end of the arc slot so as to generate a first-directional driving force; when the swing gear of the swing gear arm engages with the gear portion along the second direction, the protrusion moves toward and forces the first end of the arc slot so as to generate a second-directional driving force.
3. The media pick system according to claim 2 , wherein the part of action is a spring.
4. The media pick system according to claim 2 , wherein the second feed roller connects to a driving shaft.
5. The media pick system according to claim 2 , further including a lid disposed over the pick-up rack, and the gear portion being arranged at an inner face of the lid.
6. The media pick system according to claim 2 , further including a cover assembled to a lateral side of the pick-up rack, the swing gear lever penetrating through the cover.
7. The media pick system according to claim 1 , wherein the second feed roller has an axis, the swing gear lever has an eccentric spindle on the another end, and the part of action connects to the eccentric spindle, the eccentric spindle moves to a first position relative to the axis to form a clockwise torque about the axis, the eccentric spindle moves to a second position relative to the axis to form a counter-clockwise torque about the axis.
