A door opening and closing device includes a slider and a main link mechanism. The slider moves along a roof of the vehicle body in a front-rear direction, while supporting a proximal end portion of a back door in such a way as to be rotatable around an axis extending in a width direction. The main link mechanism includes one end and an opposite end rotatably coupled to the vehicle body and the back door, respectively. The main link mechanism adjusts a posture of the back door, depending on a door opening degree by changing a distance between a coupling point to the vehicle body and a coupling point to the back door. The main link mechanism decreases the distance as the door opening degree becomes larger.

At least one leaf of this door is equipped with a detection device comprising a mechanical detection device and a contactless sensor each capable of detecting a presence. The control circuit board comprises a control unit for movement of each leaf and a diagnostic unit, while means transfer, from the detection device in the direction of the diagnostic unit and the control unit, a first item of information representative of the activation state of the mechanical device, and a second item of information representative of the activation state of the contactless sensor. The diagnostic unit can identify a malfunction at least of the contactless detection device, when the first item of information has an active value while the second item of information has an inactive value. The invention allows redundancy to improve the availability of the detection device, while performing predictive maintenance for the operator, in particular a malfunction of the contactless sensor.

The disclosure relates to a door opener to open a door of a cassette with substrates, the opener having a first wall to engage with the cassette and having a first opening to transfer the door and the substrates and a second wall opposite the first wall and having a second opening to transfer substrates. The door opener may have a closure device to hold the door of the cassette and having first and second sides and moveable in a chamber formed between the first and second wall. The opener may have a first actuator to move the closure device in a first direction from a first closing position where the first side closes against the first wall to a second closing position where the second side closes against the second wall, and from the second closing position to a transport position in between the first and second closing positions.

A system for managing opening and closing a pocket door includes a spindle, an actuator, and brackets. The spindle extends along a longitudinal axis between first and second ends, and is configured to be coupled to the pocket door. The actuator is coupled to the spindle and is configured to cause the spindle to move axially along the longitudinal axis. The brackets are connected to the spindle at each end and are constrained from longitudinal motion relative to the spindle. The brackets are configured to affix the spindle to the pocket door. A bushing system couples each bracket to the spindle and is configured to dampen impact between the spindle and the brackets. For example, the bushing system may include lobed elements, made of a rubber material, that engage each other to transmit azimuthal forces. In some embodiments, another actuator is included to improve cycle like and redundancy.
