Abstract
A recorder in which a stylus is transported in successive line scans across a recording medium for imprinting data thereon, a stylus transport having a guide edge with which the stylus makes sliding contact, the stylus transport having a lubricating surface against which the stylus is guided for producing a thin film of lubricant upon the stylus. The lubricating film prevents wear between the stylus and the guide.
Claims2
A recorder comprising:
- a recording medium and a stylus assembly;
- a stylus transport for transporting said stylus assembly along said recording medium and in contact therewith, said transport including a guide and means for slidably securing said stylus assembly to said guide for urging said stylus assembly along a predetermined path of travel;
- lubricating means coupled to said transport for providing lubricity between said stylus transport and said guide, said lubricating means including means for contacting said stylus assembly during a movement thereof, said lubricating means comprising a block of rigid porous material containing a lubricant in the pores thereof, said stylus assembly contacting said porous material, said stylus transport including means for urging said stylus assembly against said porous material;
- and wherein
- said lubricant forms a film on a portion of said stylus assembly, said film being sufficiently thin to permit the conduction of electrical signals therethrough between said guide and said stylus assembly.

A recorder comprising:
- a recording medium and a stylus assembly;
- a stylus transport for transporting said stylus assembly along said recording medium and in contact therewith, said transport including a guide and means for slidably securing said stylus assembly to said guide for urging said stylus assembly along a predetermined path of travel, said stylus assembly producing a mark upon said recording medium in response to an electrical signal coupled to said stylus assembly from said guide;
- and
- lubricating means coupled to said transport for providing lubricity between said transport and said guide, said lubricating means comprising a block of material having pores therein for containing a lubricant, said transport guiding said stylus assembly along said lubricating block to produce a film of lubricant on a portion of said stylus assembly, said film being sufficiently thin to permit the conduction of said electrical signal therethrough between said guide and said stylus assembly.
