Driving Force Transmission Device State Switching Mechanism

A contact mechanism is introduced as an intermediary component between the rotating body and the operation unit. The contact mechanism receives force output from the rotating body and transmits it to the operation unit, ensuring reliable operation. This mediator resolves the contradiction by adding a controlled interaction point that guarantees the operation unit will actuate when needed, without requiring the entire system to be complex.

The contact mechanism is positioned to engage with the operation unit in advance of the desired state change. By receiving force output from the rotating body through the contact mechanism, the system ensures the operation unit is primed and ready to switch states reliably, preventing non-operation or stoppage issues that would occur with spring-only actuation.

The contact mechanism serves as a simple intermediary that leverages the existing force output from the rotating body to actuate the operation unit. Rather than creating a complex control system, the contact mechanism provides a direct mechanical link that ensures reliable state switching while adding minimal structural complexity.

The contact mechanism is designed to be actuated automatically by the force output from the rotating body during normal operation. This self-service approach eliminates the need for separate control systems or additional actuators, achieving reliable state switching without proportionally increasing device complexity.
