Patent number: 7614718Abstract: An automatic identification system and method for printer recordable media, which detects two or more different record media to be printed by a printer. The different record media have different load features. The system includes a transport device, a driving device, a photo encoder, a photosensor and a processor. The transport device delivers different record media. The driving device drives the transport device. The photo encoder is implemented on the transport device such that when the transport device delivers the different record media, the photo encoder can produce a position signal respectively of the different record media. The photosensor detects the position signals. The processor receives and processes the position signals to thus identify the different record media.Type: GrantFiled: April 11, 2006Date of Patent: November 10, 2009Assignee: Sunplus Technology Co., Ltd.Inventors: Yi-Che Chen, Yu-Chu Huang
