One of the first side portions of the cassette case can accommodate the second portion of the cassette case. (B) having one record/playback head and having one operating surface; (C) having at least one rotatable capstan and having one cylindrical operating surface; (D) having at least one rotatable capstan and having one cylindrical operating surface; There is a single rotational pinch loader having a single cylindrical operating surface that can be moved between a first pre-operating position and a second operating position in the recorder/player. , and (E) there is one first and second winding shaft, each winding shaft having a plurality of cam gears. The above-mentioned cleaning device includes: () There is an outer housing that can be placed in the storage chamber described above, and the outer housing has a front section, a rear section, and a first side. and a second side portion, a top wall and a bottom wall, and a first hole and a second hole in the said front portion thereof,
There is one front edge, one first window and two second windows, each of which can separately accommodate the above-mentioned record/playback head, pinch loader and capstan. () there is one first linear guiding device, which is molded into the above-mentioned outer housing and is parallel to the front edge of the outer housing; () there is one sliding unit; , which is installed in the first linear guide device mentioned above so as to be able to slide back and forth.This slide unit has a second linear guide device, which is , perpendicular to the first linear guide device, () there is a first cleaning device having a first axis, the first axis being in line with the front edge of the outer housing mentioned above; vertical,
This first purifying device is rotatably mounted on the above-mentioned slide unit, and at the same time has one first gear that rotates about the above-mentioned first axis. , which is connected to the above-mentioned first cleaning device and at the same time rotates about the above-mentioned first axis. () A second gear is installed in the above-mentioned slide unit so that it can rotate, and this second gear meshes vertically with the above-mentioned first gear. This second gear has a driven unit () a rotating unit which is mounted in the external housing mentioned above for rotation; There is an axis, and this second axis is located at a point among the center lines, and the center line is at the same distance from the left side portion and the right side portion. There is also an eccentric cam, which is mounted eccentrically in the rotary unit relative to the second axis mentioned above, and at the same time operates with the second linear guide device mentioned above. and thereby reciprocally drive the above-mentioned slide unit to slide along the above-mentioned first linear guide device. and a drive unit, eccentric to the above-mentioned second axis and mounted in the above-mentioned rotating unit, this drive unit being eccentric to the above-mentioned second axis. The coupling is effected by operation of the gear driven unit, thereby rotating the second gear mentioned above. () a first drive device, being mounted around the first hole of the above-mentioned outer housing so as to be rotatable, and at the same time by operation of the above-mentioned rotating unit; This first drive, with which it is coupled and by means of which its rotary unit is rotated, includes a hollow coupling device, by means of which the first winding shaft of the recorder/player is connected. Connects to cam gear. () a second drive device mounted around the second hole of the above-mentioned outer housing so as to be rotatable and by operation of the above-mentioned rotation unit; , are connected, thereby rotating the rotation unit mentioned above. This second drive device has a hollow coupling device, through which it is coupled to the second winding shaft of the recorder/player. () At least one secondary purifying device is movably attached to one of the two secondary windows mentioned above, thereby simultaneously displacing the capstan and pinch loader of the recorder/player. come into contact with. 2. According to the cleaning device as set forth in claim 1, the second cleaning device therein has one cover plate unit, and the two second windows in the external housing mentioned above are arranged so as to be rotatable.
