Abstract
This invention relates to a card-reversing device for use with a card printer to perform printing on both sides of a card. According to the present invention, the card-reversing device includes a transmission unit capable of feeding the card, a rotary mean capable of turning the card upside down, a friction medium providing rotation torque for the rotary mean and a lock unit capable of controlling the rotation of the rotary mean. In addition, the card-reversing device of the invention is capable of turning over a card without damage as the turnover operation is abnormally stopped, and it possesses simple, easily assembled and inexpensive properties.
Claims9
A substrate turning device for use with a printer to perform printing on both sides of a substrate, comprising:
- a transmission unit including a rotation shaft driven by a feeding motor for transporting said substrate;
- a rotary means mounted on said rotation shaft for retaining and turning said substrate upside down;
- a friction medium disposed between the connection of said rotary means and said rotation shaft to transport a rotation torque so that said rotary means can be driven to rotate by said transmission unit;
- and
- a brake for alternately braking the rotation of said rotary means;
- wherein said brake includes a solenoid, a lock bar and a gear, further wherein said solenoid controls said lock bar to stop the rotation of said gear.
