Abstract

In order to force the cell of an electro-optic display device into a defined position against a stop means rigidly mounted on the housing, for the purpose of zebra-rubber contacting with a pc motherboard rigidly installed in the housing, without obstructing the installation of the cell behind the sight opening of the housing, or without posing the hazard of damaging the sharp glass fracture edges of the glass plates of the cell, at least one leaf-type spring is clamped opposite the stop, such spring supporting itself in the direction of the stop on the edge of a glass plate of the cell, on the one hand, and in the opposite direction against an abutment, on the other hand, such abutment being rigidly mounted on the housing. The spring is punched in the form of a flap with an approximately U-shaped section from the lateral zone of a foil flatly resting against the cell, such flap bridging the free space between the cell and the abutment. Each of the flaps so defined is bulged from the plane of the foil and clamped in said free space as a bencing or compressing spring by a die which, in the course of the assembly of the display device, applies pressure to the respective flap, such die…
