Image scanner having driving mechanism to synchronize movement of transmission-mode light source and image pickup device

摘要

An image scanner having a driving mechanism to synchronize the movement of a transmission-mode light source and a carriage mounted therein an image pickup device is disclosed. The driving mechanism includes a driving motor and two transmission devices both connected to the driving motor. One of the transmission devices connects the carriage to the motor. The other transmission device penetrates through the scanning platform at an upper end where an upper cover and a lower housing of the scanner housing are pivotally connected to connect the transmission-mode light source to the motor. Thereby, the two transmission devices are simultaneously driven by the motor to move the carriage and the transmission-mode light source synchronously.
