ABSTRACT:
A scrolling device includes a first disk, a second disk and a middle disk wherein a shaft extends through the disks and two setting devices are respectively disposed between the middle disk and the respective one of the first and the second disk. A casing receives the three disks therein and is driven by a motor which is controlled by two control members disposed to the first and second disk. Each of the setting devices include a base gear and a plurality of wheels each of which has a toothed periphery and a cam member formed in a first side thereof, and two teeth extending laterally from a second side thereof, a setting member and a positioning member pivotally and respectively disposed between the middle disk and the respective one of the first and the second disk. The setting members each have gears engagable with the wheels and base gear, and a plurality of plates engagable with the cam members to set the wheels. The positioning members each have a plurality of studs which are able to be received in a respective cavity defined in each of the wheels whereby the wheel may be set, and a push member which is able to touch the control member to stop the motor. The shaft has a gear device meshed with a toothed inner periphery of the casing so that the rotating casing is stopped when the studs of the positioning members are received in the cavities of the wheels, while the push members actuate the control members.
