BACKGROUND OF THE INVENTION It is known from practice for force to be transmitted from the drive device to the conveying belt of a belt conveyor via friction fitting. The friction between a driven carrying roller and the conveying belt, for example, may even be sufficient for this purpose. The rest of the carrying rollers are mounted in a movable manner and rotate along. DE 42 44 170 C2 discloses a belt conveyor having an endless conveying belt, the latter being driven by means of a forcetransmission device which is present in the form of a friction wheel. A drive shaft extends beneath the bottom strand of the conveying belt. On the inner radius of the belt curve, a motor is connected as a drive device to the drive shaft and, in the region of the outer radius, a friction wheel is seated on the drive shaft and is in contact with the outer surface of the conveying belt. In this case, the friction wheel interacts with a carrying roller functioning as counterpressure roller. The drive shaft is mounted such that it can be moved at an angle both in the region of the outer radius and in the region of the inner radius of the belt curve. The movableangle mounting of the drive shaft allows adaptation of the extent to which the friction wheel is pressed against the conveying belt in proportion to the actual load. In this way, the wear is reduced if, in partload operation, the conveying belt is only subjected to the contactpressure force which is necessary for this purpose. Although the belt conveyor known from DE 42 44 170 C2 reduces the wear of the conveying belt, it cannot rule it out altogether. The task of conveying foodstuffs or other goods which are to be kept clean involves, in addition to the mechanical damage to the conveying belt, the aspect of hygiene and of keeping goods clean. The abraded surface particles of the conveying belt could have a considerable adverse effect on the quality of the goods which are to be conveyed. Moreover, the known belt conveyor requires an extremely high level of structural outlay as far as the movable mounting of the separate drive shaft is concerned. SUMMARY OF THE INVENTION Taking as departure point the belt conveyor known from DE 42 44 170 C2, the object of the invention is to specify a belt conveyor of the type in question which largely rules out any adverse effect to the surface of the conveying belt of the belt conveyor by the forcetransmission device. According to a particularly preferred configuration, the belt conveyor is intended to require just a low level of structural outlay. The above object is achieved by the features of Patent claim 1. According to the latter, a belt conveyor of the type in question is configured such that a pair of elements which interact with one another with a form fit is provided for forcetransmission purposes, and that one element is assigned to the forcetransmission device and the other element is assigned to the conveying belt. According to the invention, it has been found that the surface of the conveying belt is not adversely affected as a result of the action of the forcetransmission device if a separate pair of elements is provided in order to realize force transmission. It has also been found that the use of a pair of movementconverting elements which are known per se and interact with one another with a form fit largely eliminates the disadvantages which are known in the case of frictionfitting movement conversion, in particular wear and abrasion. According to a preferred exemplary embodiment of the belt conveyor according to the invention, the pair of elements could be present as toothed ring and toothed belt, the tooth flanks of the toothed ring and of the toothed belt interacting with one another. It would be possible for the toothed ring to be assigned to the forcetransmission device and for the toothed belt to be assigned to the conveying belt. As far as a particularly low level of structural outlay is concerned, a preferred configuration of the abovementioned exemplary embodiment provides that the toothed ring is assigned to a carrying roller, and the latter thus simultaneously assumes the role of the forcetransmission device. Via a journal projecting from the carrying roller, the drive takes place by means of a motor. The toothed ring could be plugged onto the carrying roller and fixed releasably— for example via a shaft/hub connection or a feather key— to the same. In the case of a pl
