Abstract

An imaging device for document imaging may comprise a housing and an optical system having a lens system and an optical detector. The optical system is responsive to image light reflected by an object and produces image data representative of the image light. The optical system is pivotally mounted to said housing and is biased toward a vertical orientation inside said housing by gravity.

Claims

1. An imaging device for document imaging, comprising:

a body portion;

an optical assembly;

a pivotal mounting bracket, whereby said optical assembly is pivotally mounted to said body portion; and

a lock having a locked position and an unlocked position, whereby said optical assembly may be locked into place relative to said body portion when said lock is in said locked position, and where said optical assembly may pivot about said pivotal mounting bracket when said lock is in said unlocked position, wherein said lock comprises at least one locking fingers operatively associated with said body portion, said at least one locking fingers engaging with said optical assembly when said lock is in said locked position to hold said optical assembly in place relative to said body portion.

2. An imaging device for document imaging, comprising:

a body portion;

an optical assembly;

a pivotal mounting bracket, whereby said optical assembly is pivotally mounted to said body portion; and

a lock having a locked position and an unlocked position, whereby said optical assembly may be locked into place relative to said body portion when said lock is in said locked position, and where said optical assembly may pivot about said pivotal mounting bracket when said lock is in said unlocked position, wherein said pivotal mounting bracket comprises a gimbal, and wherein said lock comprises a ring cap comprising a ring which may be slid around said optical assembly to rest between said optical assembly and said body portion, preventing said optical assembly from moving relative to said body portion.
