Abstract
The invention discloses a cable accommodating structure used for a plateform-type scanner. One end of a cable is electrically connected to a circuit mainboard, and the other end thereof is electrically connected to a bare engine module assembly and the cable can stretch and bend below the scanning plateform with the movement of the bare engine module assembly. The cable gathering and releasing structure mainly comprises a cable accommodating structure which can accommodate the cable. When the cable is forcedly pulled out in the direction shown in the attached drawing, the radius of the cable shrinks because of the elasticity of the cable, therefore the cable is released, and at the same time the cable is subjected to an elastic force in a opposite direction to F, therefore, the cable should be tensed; when the force F is released, the cable should be driven to automatically roll back the original position in a stander. The cable accommodating structure can ensure that the cable is always kept in level condition, thereby preventing the scanning plateform from being rubbed with the cable and being contaminated.
