Abstract
PURPOSE: To provide the device of good operating characteristic by so forming the device that when an original pressure contact plate is opened said plate may be stayed still in the desired position.
CONSTITUTION: When a pressure contact plate 3 is raised to open, a guide shaft 18 turns clockwise, causing a slide spring seat 19 to move to the end direction of the guide shaft 18. The height of a spring 22 will then subsequently increase. When the opening angle of the pressure contact plate 3 and glass plate 9 exceeds the specified angle, the moment in the clockwise direction owing to the elastic force of the coil spring 22 overcomes the moment in the counterclockwise direction owing to the own weight of the pressure contact plate 3, as a result of which the pressure contact plate 3 automatically and increasingly moves upward. Upon contacting of the end of the slide spring seat 19 with a stopper 25, the pressure contact plate 3 stops rising and stays still, hence operations such as replacement of originals, etc. may be performed by both hands and this is convenient. Further it is so constructed that even when the pressure contact plate 3 is opened by 90° or more it stays still.
