A first reading sensor reads a first surface of a document. A second reading sensor reads a second surface of the document. An elastic body presses the second reading sensor toward the document that is conveyed toward an other side in a first direction. A conveyance guide includes a protrusion accommodating the elastic body. A friction pad contacts, from below, the document supported by a document placement surface. A recess is recessed downward from the document placement surface. A feed roller at a lowermost position enters the recess. An opening is formed in the document placement surface. The opening allows an exposed surface of the protrusion to be exposed to a side to which the document placement surface faces. The friction pad, the recess, and the opening are arranged away from one another in a second direction perpendicular to the first direction and an upper-lower direction.

Methods and systems are disclosed for determining at least one actuation characteristic of an imaging device. For example, one method includes determining a target distance to move a lens by an actuator to focus a scene on an image sensor, where moving the lens by the actuator causes an associated lens vibration having at least one actuation characteristic, determining a scan sequence having a plurality of successive measurements, each measurement having at least a first measurement parameter and subsequent measurement parameter, each measurement parameter including at least one step and at least one time delay, moving the lens the target distance for each successive measurement based on the measurement parameters of each successive measurement, measuring a performance indicator of each successive measurement, and determining at least one actuation characteristic based on the first measurement parameter of the measurement having the highest performance indicator.

Methods and systems are disclosed for damping unwanted vibrations or ringing of a lens in an imaging device. For example, one method includes determining a target distance to move a lens, and dividing the target distance into multiple steps having at least a first step and a subsequent step, moving the lens, via an actuator, by the first step, thereby causing a first vibration, retrieving a damping parameter indicative of a time delay, the damping parameter being based on at least one characteristic of the actuator and the number of steps, and repeating said moving the lens at least one subsequent step after delaying the subsequent step by one of the damping parameters, each moving the lens a subsequent step causing a subsequent vibration, and the damping parameters affecting the vibration such that the first and subsequent vibrations at least in part modify each other to lower overall vibration.

The present invention describes a method for electronically and physically archiving documents, said method having the following steps: a) producing a file by a recording a digital image of the physical document using a camera; b) storing at least some information based on the file captured in step a) in an electronic memory; c) filing the captured physical document in a container or in one of a number of containers provided for the physical filing of the documents to be archived; d) linking a unique container identification and/or position information of the physical document in the container with the file produced in step a) and/or the information stored in an electronic memory in step b), and e) storing, in a database, the file produced in step a) and/or the information stored in an electronic memory in step b) with the link obtained in step d).

The present invention also describes a container for carrying out the method according to the invention and also a computer program associated with the method, and an electronic data storage medium.
