Abstract

La présente invention permet de déverrouiller de manière forcée un couvercle même dans un état dans lequel le couvercle est verrouillé par un élément de verrouillage. Un dispositif de transfert de feuille 1 comprend : un corps de boîtier 21 ; un premier couvercle 22 ; un élément de verrouillage (élément rotatif 93) ; un capteur de température qui détecte une température à l'intérieur du corps de boîtier ; une unité de commande ; et un élément de déverrouillage forcé CR. Le premier couvercle 22 se déplace entre une première position de fermeture dans laquelle une ouverture du corps de boîtier 21 est fermée et une première position d'ouverture dans laquelle l'ouverture est ouverte. L'élément de verrouillage se déplace entre une position de verrouillage dans laquelle le premier couvercle 22 est verrouillé à la première position de fermeture et une position de déverrouillage dans laquelle le premier couvercle 22 est déverrouillé. L'unité de commande positionne l'élément de verrouillage à la position de verrouillage lorsqu'une température détectée du capteur de température est une première valeur prescrite ou plus, et positionne l'élément de verrouillage à la position de déverrouillage lorsque la température détectée est inférieure à la première valeur prescrite. Lorsque le premier couvercle 22 est dans la première position de fermeture, l'élément de déverrouillage forcé CR peut être actionné depuis l'extérieur du corps de boîtier 21 pour déplacer l'élément de verrouillage de la position de verrouillage à la position de déverrouillage.
