Display retaining means assembly

摘要

A sheet fixing device for fixing a sheet such as a transparent map film sheet on the display surface of the display surface of a cathode ray tube of an information display apparatus such as an automobile position display apparatus. The device has a sheet pressing member having provided with sheet pressing rubber portions and adapted to be biased toward the display surface by a plurality of independent biasing member spaced from one another. The sheet pressing member is adapted to be driven by sheet pressing member lifting levers which in turn are actuated by cams adapted to be rotated together with a sheet guide. When the sheet guide is rotated to the position for taking out the sheet, the cams actuate the sheet pressing member lifting levers to cause the latter to drive the sheet pressing member away from the display surface of the cathode ray tube.
