Adjustable Sheet Guiding Apparatus with Movable Plates

The patent applies the dynamics principle by making the guiding members movable rather than fixed. The guiding members can move toward and away from each other along the shelf, allowing the guiding area to dynamically adjust its size according to different sheet dimensions. This transforms the static fixed guiding area into a dynamic adjustable structure, resolving the contradiction between adaptability and space occupation.

The patent implements the nesting principle by allowing the guiding members to be positioned at different locations along the shelf, with the ability to nest or overlap in their movement paths. The adjustable plates and push bars are nested within the guiding member structure, enabling compact storage when not in use and smooth expansion when needed, thus reducing the overall space requirement while maintaining adaptability.

The guiding members are designed to move dynamically along the shelf, allowing the guiding area to be enlarged only when needed for different sheet sizes. When accommodating standard sheet sizes, the guiding members remain in their compact default position, thus avoiding unnecessary increase in apparatus size while maintaining the capability for enlargement when required.

The apparatus is segmented into multiple independent components: guiding members, adjustable plates, push bars, and rotating members. Each segment can move and adjust independently, allowing the guiding area to be enlarged selectively in specific directions or to specific degrees, rather than requiring the entire apparatus to expand, thus minimizing the overall size increase.

The apparatus employs spring mechanisms that automatically return the guiding members and adjustable plates to their default positions after adjustment. The second springs on the push bars and the first springs on the adjustable plates provide self-resetting functionality, eliminating the need for additional motors or actuators to reset the components, thus reducing overall device complexity while maintaining adjustability.

The push bars act as intermediary elements between the rotating members and the adjustable plates. The rotating members convert rotational motion into linear motion of the push bars, which then transmit this motion to the adjustable plates. This intermediary mechanism simplifies the overall control structure by providing a mechanical transmission path that is simpler than direct actuation of the adjustable plates.
