A belt driving controller is disclosed. The memory modules comprise at least one low-speed memory and one high-speed memory; both store an interrupt vector table individually for recording the entry instruction of interrupt service routines. A tap, taps the data imparted from the print head and correlates it with the imaged data to determine the media speed, the image alignment, label analysis, weighing of blemishes, the gaps printed on a label, and other criteria. A thinned portion is formed at least at a leading end of each core crimping piece and is thinner than the base plate. The control module controls the first actuator to tilt the passenger side mirror when the mirror selection signal indicates the mirror selection switch is in the passenger position and the reverse gear signal is indicative of the vehicle being in a reverse gear.
