<p>A flatbed scanner with a counterweight (202) attached to the carriage cable (222) on the return loop in a position opposite of the carriage (200). The counterweight (202) may be approximately equal to the weight of the carriage (200). The counterweight (202) may move in the opposite direction as the carriage (200). For example, as the carriage (200) moves from the front to the back of the scanner chassis, the counterweight (202) would move from the back to the front of the scanner chassis. If the scanner is on an incline, as the carriage (200) is moving up the incline, the counterweight (202) would be moving down the incline and vice versa with the counterweight (202) actually countering the weight of the carriage (200). With a counterweight (202), a scanner can be used at any angle from flat to vertical or any rotational position without changing the motor torque requirements. <IMAGE></p> |
