Abstract:
The present invention is directed to a hand-held scanning device in which the scanning device housing window is attached directly to the optical assembly. In this manner, alignment between the window and the optical assembly may be maintained even when the housing is being subjected to stress. The window is also designed to float with respect to at least a portion of the housing, thus allowing the housing to flex without causing movement of the window relative to the optical assembly. A tortuous path seal arrangement may be provided between the window and the housing. The tortuous path seal allows the housing to move relatively to the window, and yet inhibits the entry of dust and other contaminants into the interior of the housing through the space provided between the window and the housing.
Abstract:
An image forming optical element is provided, in which a first lens, a second lens, and a light guiding unit that leads the light input from the first lens, to the second lens, the light guiding unit has a curved shape of a first curve portion and a second curve portion from the first lens to the second lens, a first reflection face that reflects the light input from the first lens, to the second curve portion, is formed on an outer peripheral face of the first curve portion, a second reflection face that reflects the reflected light to the second lens is formed on an outer peripheral face of the second curve portion, the light input to the first lens travels in the transparent medium until reading the second lens, is output from the second lens, and then forms an image at magnification of erection equal-magnification.

Abstract:
The present invention is directed to a hand-held scanning device (10) in which the scanning device housing window (150) is attached directly to the optical assembly (40). In this manner, alignment between the window (150) and the optical assembly (40) may be maintained even when the housing (20) is being subjected to stress. The window (150) is also designed to float with respect to at least a portion of the housing (20), thus allowing the housing (20) to flex without causing movement of the window (150) relative to the optical assembly (40). A tortuous path seal arrangement (360) may be provided between the window (150) and the housing (20). The tortuous path seal (360) allows the housing (20) to move relatively to the window (150), and yet inhibits the entry of dust and other contaminants into the interior(21) of the housing (20) through the space provided between the window (150) and the housing (20).
