  • Patent number: 5546686
    Abstract: An electromotive device for exhibiting pictures has an ascending carrier guided along rear guiding rails and a descending carrier guided along front guiding rails. The ascending carrier ascends and the descending carrier descends picture keeping members one by one. Upper compressing levers compress the picture keeping members at an upper position toward a front exhibition window when the ascending carrier is ascended, and lower compressing levers compress the picture keeping members at a lower position toward a rear exhibition window when the ascending carrier is descended. According to the electromotive device, a large quantity of exhibits such as photographs or pictures can be stored in good condition for a long time, and operational noise can be reduced. Further, the electromotive device provides ornamental value.
