Abstract

Disclosed is a magnification device with multiple orientations. This allows a blind or low vision user to select the best orientation for the task being performed. The device includes both opened and closed orientations. It is further configurable into document reading, near object inspection, far object inspection, and self-inspection modes. The camera of the device can be manipulated by the user depending upon which of these orientations is selected. Furthermore, the camera automatically adjusts itself into one of two pre-set configurations whenever the device is opened or closed.

First claim

What is claimed is:

1. A device for displaying magnified images of an object comprising:
a housing having an interior and opposing faces, a screen positioned within one of the faces;
a base pivotally connected to the housing, the base having opened and closed configurations with respect to the housing;
a camera assembly for taking images of the object and displaying the images on the screen, the camera assembly being rotatably mounted within the interior of the housing between first and second positions, a spring with a spring force, the spring interconnected to the camera assembly, the spring force urging the camera assembly into the first position;
a stop mechanism positioned within the interior of the base, the stop mechanism being slidable between upper and lower positions within the housing, whereby positioning the stop mechanism in the upper position prevents the camera assembly from rotating to the first position, and whereby positioning the stop mechanism in the lower position allows the camera assembly to rotate to the first position;
a brake for selectively counterbalancing the spring force, the brake positioned within the interior of the housing and including a band with first and second ends, the first end of the band fitted to the camera assembly and the second end of the band interconnected to the interior of the housing, the brake having an engaged position where the brake counterbalances the spring force to permit the position of the camera to be adjusted by hand, the brake also having a disengaged position wherein the spring force is permitted to rotate the camera assembly.

2. The device as described in claim 1 wherein placing the base into the opened configuration causes the stop mechanism to slide to the lower position.

3. The device as described in claim 1 wherein placing the base into the closed configuration causes the stop mechanism to slide to the upper position.

4. The device as described in claim 1 wherein the base comprises two spaced feet.

5. The device as described in claim 4 wherein the camera assembly is pointed between the spaced feet when in the first position.

6. The device as described in claim 1 wherein the screen is positioned within a front side of the housing and the camera assembly has a self-viewing orientation allowing for objects located on the front side of the housing to be imaged.

7. The device as described in claim 1 further comprising a coil spring connected between the interior of the housing and the second end of the band, wherein the force of the coil spring is used to counterbalance the spring force when the brake is engaged.
