Word processor-controlled printer output bin lock box
摘要:
A lockbox is provided for a word processor printer output bin attached to a printer. The lockbox, which is insertable and removable from the output bin, is locked in the bin upon insertion, and can only be removed by disengagement of a first locking means. The lockbox has a security door which is positioned in a paper receiving position upon insertion into the output bin and which must be closed in order to remove the lockbox from the output bin.
