Link Mechanism Shutter for Connector Protection

The patent combines the shutter mechanism with the existing link mechanism that connects the cover opening movement to the shutter. The link mechanism serves dual purposes: it controls the shutter during normal operation and also positions the shutter to protect the connector when the cover is opened. This merging of functions avoids adding separate protection mechanisms, thereby improving connector protection while minimizing increases in device complexity and cost.

The link mechanism is designed to perform multiple functions: it controls the shutter during image forming operations, and simultaneously positions the shutter to protect the power supply connector during maintenance access. By making the link mechanism universal and multi-functional, the patent achieves connector protection without adding dedicated protection components, thus improving reliability while keeping device complexity and cost minimal.

The link mechanism automatically responds to cover opening movement without requiring separate control systems or additional actuators. The mechanical connection between the cover opening action and the shutter movement creates a self-service system where the maintenance access action itself triggers the protection mechanism. This self-service approach improves connector protection while minimizing the addition of complex control mechanisms.

The patent merges the cover opening mechanism with the shutter control mechanism through the link. The same mechanical linkage that enables cover opening also controls shutter position, combining two functions into one integrated system. This merging reduces the need for separate control mechanisms, thereby improving connector protection while keeping the overall device complexity minimal.
