Abstract: An elevator door apparatus includes an engaging device which engages car doors with hall doors. The engaging device uses a spring unit to urge a movable vane provided in each of the car doors. While the doors are moving, engaging rollers supported by the hall doors are sandwiched between the movable vane and a fixed vane. Thus, the driving forces of the car doors are transmitted to the hall doors. When the hall doors reach a door stop position, the movable vane is moved away from the fixed vane. Thus, the car doors are disengaged from the hall doors. At this time, a direction in which the elastic force of the spring mechanism acts is switched. Consequently, the car doors and the hall doors are stably held so that the car doors remain disengaged from the hall doors.

Abstract: A door apparatus is provided with engaging elements for actuating a locking mechanism of a hall door and a pair of engaging vanes which can be opened away from or closed toward each other so that they pinch the engaging elements between them to hold the locking mechanism in an inactivated state when in their closed state. The closed state of the two engaging vanes is maintained by a cam mechanism and a retention mechanism. The closed state of the two engaging vanes can also be maintained by the retention mechanism after the hall door is moved in a door closing direction to cancel maintenance by contact with the cam mechanism. Both the engaging vanes are moved in an opening direction to actuate the locking mechanism by means of a reaction force generated when the hall door reaches a door-stop position and stops there.

Abstract: A hall door apparatus of an elevator includes a gate frame, a doorsill, and a door panel. The gate frame is provided in an entrance port between an elevator hall of a building and an elevator shaft. The doorsill is arranged in a lower portion of the gate frame. The door panel is of a biparting door type, and is set on the doorsill to face the gate frame. Sealing members are made of an elastic material such as a rubber, and seal gaps between the door panel and a jamb portion and header panel portion of the gate frame, and between the door panel and the doorsill.

Abstract: An internal sensor is moved in a direction of stacking of note bundles within a cashbox along bands of the bundles. The bands of bundles are detected in accordance with movement of the internal sensor. The number of bundles within the cashbox is counted on the basis of a difference in level between a sensor output obtained when the band is sensed and a sensor output obtained when a location between the bundles, where the band is absent, is sensed.
