Steps including setting and registering individual identification means for each individual applicable to individual data of an unspecified number of the general public, reserving tangible and/or intangible various goods controlled by an information data control unit for an individual whose individual identification means have been set and registered through communication devices, and setting a reservation code to the reservation data for each of various goods reserved and notifying the individual are performed.

Abstract: Disclosed is a method of teaching a moving part to trace a path, the method comprising the steps of determining a curved condition of the teaching path on the basis of a difference between a path length and a straight distance from a first point to a second point on the teaching path and an angle made by the first and second points and a third point, and selectively storing the first, second and third points in accordance with the results of the determination. The first, second and third points are stored as path data in a memory when the difference is greater than a reference length and the angle is smaller than a reference angle. On the other hand, the first and second points are stored therein when the difference is greater than the reference length and the angle is greater than the reference angle.

Abstract: An automatic document feeder for use with a facsimile apparatus, a copier or the like includes a separator roller and feed rollers which are mounted on a common shaft and each is provided with a spring clutch. While the separator roller cooperates with a friction roller for separating documents from a stack on a tray one at a time, the feed rollers cooperate one with another feed roller, which is provided with a one-way clutch, for feeding the separated document. A reversible stepping motor is selectively driven in opposite directions depending upon the position of a document in a predetermined path, so that the coactive feed rollers selectively serve as drive rollers and follower rollers. The separator roller rotates in the same direction as the feed rollers which are coaxial therewith only when the latter serves as drive rollers.
