A system for dispensing components one-at-a-time upon demand for utilization comprises a component handling assembly and a buffer assembly. The component handling assembly receives bulk quantities of the components and when activated, properly orients each component and supplies the components in a randomly timed sequence to the buffer assembly. The buffer assembly comprises a cylindrical upper receiving housing having a plurality of cylindrical through-chambers radially disposed in a circular pattern and rotatable about a central generally vertical axis. A cylindrical lower dispensing member is closely aligned and coaxially rotatable both independently and together with the receiving housing. The dispensing member has a planar upper surface which forms a bottom cover for the chambers in the upper receiving housing and has a single passageway that can be aligned with each of the upper receiving chambers to dispense a component.

Apparatus for dispensing elongated small mechanical parts

An optical control system for use with a transducer positioning apparatus of a type having a lead screw coupled to the transducer head for controllably positioning the head relative to a selected track on a recording medium, wherein the lead screw is controllably rotated by a geneva mechanism that includes a geneva wheel coupled to the head screw and a geneva driver driven by a reversible d-c motor. The optical control system includes an optical disc that rotates in correspondence with the geneva driver and that has two optical tracks, one utilized in producing an error signal that varies substantially linearly with the angular position of the disc and the other utilized in producing an engagement pulse signal whenever the pin of the geneva driver is engaged in a slot in the geneva wheel. When it is desired to index the transducer head to a selected track, a pulse is coupled to the motor to drive the geneva driver in the appropriate direction, such pulse being terminated only after it has been determined that the geneva driver pin has rotated out of engagement with a slot in the geneva wheel. Thereafter, the error signal is coupled to the motor to automatically position the pin away from the geneva wheel and thereby hold the wheel, and thus the transducer head, in their respective positions.

Optical control system for transducer positioning apparatus

Apparatus for positioning a transducer head in a prescribed relationship relative to a selected track on a recording medium. The apparatus includes a lead screw that is threadedly coupled to a bracket for supporting the transducer head, whereby a controlled rotation of the lead screw functions to move the transducer head along the surface of the recording medium, to the prescribed position. Rotation of the lead screw is controlled by a geneva mechanism that includes geneva wheel coupled to the lead screw and a geneva driver driven by a reversible d-c motor. Each revolution of the geneva driver rotates the geneva wheel, and thus the lead screw, through a prescribed angle, such that the transducer head is moved along the recording medium by a prescribed amount, such as one track spacing.

A xerographic copier including a novel photoconductive belt and drive structure is disclosed. The thin metal belt is provided with at least one transverse break or gap and is preferably formed of two belt segments. In use, the break or gap between segments are held in end-to-end relationship by tow bars which captivate the edges of the segments, hold them in position and provide mechanical bias therebetween. The photoconductive belt is driven in a unique manner by means of the tow bars which are drawn about a non-circular path by an inelastic but flexible guide means such as chains and sprockets. The belt passes over drums which support the belt and define it's path but do not drive it. The drums include a low friction surface and provision (a soft layer) for accommodating small foreign objects that may pass between the belt and the drums without hurting the belt. The tow bars project only on the inner side of the belt and provision is made for accommodating them on the drums so as to not excessively bend the photoconductor bearing surface of the belt. This provision is at least one channel in each drum which are driven in synchronism with the tow bars and so sized and spaced as to have the channels receive the tow bars as they travel about the path.
