The device includes a housing (14) adapted to be inserted in the player/recorder in a cleaning position, a drive mechanism (18) and wiper and (16) connected within the housing (14) for providing oscillating movement, and a cleaning head (20) connected to the wiper arm (16) for cleaning the head assembly (12). The cleaning head (20) comprises a rigid body (82) having a plurality of cleaning materials (84, 86, 88) extending forwardly out of the rigid body (82). One of the cleaning materials is a solution-holding material (84) characterized by its ability to absorb a cleaning solution, for spreading the cleaning solution on the head assembly (12). Another cleaning material (86, 88) comprising a relatively stiffer material for scrubbing the head assembly, is positioned on both sides of the solution-holding material (84). In use, the drive mechanism (18) within the housing is driven by the tape player and/or recorder such that it moves the wiper arm (16) with the attached cleaning head (20) back and forth along a transverse path on the head assembly (12) to be cleaned as it both spreads a cleaning solution and scrubs the area clean. The device also includes a cleaning cartridge (150) for cleaning the drive capstan and pinch roller of the associated player/recorder. The cleaning cartridge is provided with a first cleaning pad (154) for cleaning the pinch roller and a second cleaning pad (156) for cleaning the drive capstan. The cleaning cartridge pivots so that it does not blow the invention of the device into the player/recorder and to ensure the drive capstan and pinch roller are properly cleaned. ## Claims ### Claim 1 Apparatus for cleaning a pinch roller and capstan of a magnetic tape player/recorder comprising: a housing adapted to be inserted in the tape player/recorder in a cleaning position, said housing defining an opening for receiving the drive capstan of the player/recorder; and a cleaning cartridge including: a cartridge body pivotally mounted in said housing adjacent said drive capstan opening; a first cleaning pad secured to said cartridge body and positioned to abut the drive capstan of the player/recorder when the drive capstan is disposed in said drive capstan opening of said housing; a second cleaning pad secured to said cartridge body and positioned to abut the pinch roller such that contact of the pinch roller against said second cleaning pad moves said first cleaning pad into contact with the capstan; and a biasing member coupled to said cartridge body, said biasing member positioned to contact said housing to pivot said cartridge body so that said first cleaning pad is normally located away from the center of said housing drive capstan opening. ### Claim 2 (depends on 1) The cleaning assembly of claim 1, wherein said cleaning cartridge biasing member is a spring arm integrally attached to said cartridge body. ### Claim 3 (depends on 1) The cleaning assembly of claim 1, wherein said cartridge body is releasably, pivotally secured to said housing. ### Claim 4 (depends on 1) The cleaning assembly of claim 1, wherein said housing is provided with at least one mounting pin and said cartridge body is releasably secured to said at least one mounting pin. ### Claim 5 (depends on 1) The cleaning assembly of claim 1, wherein said cartridge body is formed with a first slot and said first cleaning pad is partially seated in said first cartridge body slot. ### Claim 6 (depends on 5) The cleaning assembly of claim 5, wherein said cartridge body is formed with second and third slots, a first end of said second cleaning pad is partially secured in said second cartridge body slot, a second end of said second cleaning pad is secured in said third cartridge body slot, and said cartridge body is shaped so that an exposed portion of said second cleaning pad between said ends of said cleaning pad abuts the pinch roller of the tape player/recorder. ### Claim 7 (depends on 6) The cleaning assembly of claim 6 wherein said housing is provided with at least one mounting pin and said cartridge body is releasably secured to said at least one mounting pin.
