A protection device for a lens used in a scanning apparatus for imaging data on photographic film, comprises a plate (201) and having a finger gripping portion (209,210), a member (202) slidably retained in said plate, a glass piece (206) removably carried by the member, and a biasing member operatively associated with the member for selectively permitting secure holding of the glass piece on the member and easy removal of the glass piece from the member. The plate (201) is provided with a biasing device for securely retaining the member (202) in a desired location such that the glass piece (206) is in a predetermined lens protecting position. A switch is associated with the plate such that the switch is moved to an open position upon movement of the member away from the plate. The biasing member is a pivotally mounted spring (215) configured to hold the glass piece in a desired location on the member and has V-shaped portions to engage portions of the member for positive locking of the spring in the member. <IMAGE> |
