[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cassette type pinch roller cleaner.

[0002]

[Prior art]

 Conventionally, in order to clean members such as pinch rollers of tape recorders, a cassette-type cleaner is provided with a pinch-roller cleaning pad.The cassette-type cleaner is attached to the tape recorder, and the cleaning pad is pressed against the pinch-roller to adhere to the pinch-roller. The dirt such as the magnetic coating powder is removed. In the conventional pad, a pad supported by a spring or a fixed holder is made to face the pinch roller insertion port of the cassette type cleaner, and pressed against the pinch roller which enters the insertion port.

[0003]

[Issues to be solved by the device]

 However, the conventional cleaning pad has a structure that cannot be replaced, and since the pinch roller is made of rubber and magnetic powder is particularly likely to adhere to the cleaning pad, the cleaning pad is particularly easy to get dirty. Therefore, a cleaning pad that can be easily replaced or updated is desired.

[0004]

[Means for Solving the Problems]

 The cassette type cleaner of the present invention has a pinch roller insertion opening, and when the cassette cleaner is mounted on the cassette mounting portion of the cassette recorder, the pinch roller enters the pinch roller insertion opening and comes into contact with the pinch roller cleaning member. The feature is that an elongated cleaning member having one end facing the pinch roller insertion opening of the cassette is provided so as to be fed by a feed roller that can be rotated from the outside. For example, the feed roller is provided with a plurality of ridges extending in the axial direction at regular intervals along the outer peripheral surface of the cylindrical body to feed the cleaning member by the amount of rotation of the cylindrical body from the outside. In case of, fix the cleaning member in that position. Further, the feed roller has a shaft exposed to the outside of the cassette, and has a portion on the shaft end at which an operating tool can be engaged from the outside.

According to the cassette type cleaner of the present invention, when the contact surface of the pinch roller cleaning member with the pinch roller becomes dirty, the clean surface can be renewed by feeding an appropriate amount. If necessary, the dirty surface can be cut off.

[Explanation of Examples]

 Hereinafter, an embodiment of the cassette type cleaner according to the embodiment of the present invention will be described in detail. FIG. 1 is a plan view of a cassette type cleaner in which a part of an upper case is cut away, FIG. 2 is a front view of the relevant part, and FIGS. 3 to 6 are detailed views of a feed roller of a cleaning member.

1 and 2, the cassette type cleaner is provided with a pair of rotary hubs 5 and 7 in a case formed by joining an upper case 1 and a lower case 3 together with outer peripheral walls, and a cloth and A cleaning tape 9 that absorbs a cleaning liquid, such as a woven cloth, is wound around and wound around the cleaner by pulling it out to the front. A capstan insertion hole 11, a pinch roller insertion opening 13, and a magnetic head insertion opening 15 are formed in the front portion of the cleaner.

Although not the subject of the present invention, in the present embodiment, a shaft 17 stands up from the case behind the magnetic head insertion port 15, and a lever 19 is pivotally attached thereto. A holder 21 is loosely fitted to the bead at the tip of the first arm 25 of the lever 19. The holder 21 holds a cleaning member 23 such as felt or nonwoven fabric facing the capstan insertion hole 11. The holder 21 is guided in the front-rear direction by guide members 59 and 61 provided in the lower case 3 so that the holder 21 can enter and exit the capstan insertion hole 11. The end portion of the second arm 27 of the lever 19 is an operation end of the magnetic head, and is arranged near the entrance of the magnetic head insertion opening 15. The lever 19 is biased in the clockwise direction in FIG. 1 by a leaf spring (or a coil spring) 29. When the magnetic head pushes the operating end of the lever 19, the lever 19 rotates counterclockwise and the cleaning member 23 can be pushed against the capstan via the holder 21.

Further, although not the subject of the present invention, the cassette type cleaner of the present embodiment is provided with means for magnetic head cleaning. In FIG. 1, a liquid reservoir 31 is provided on the upper surfaces of the hubs 5 and 7, and slits 33 are formed at substantially regular intervals along the periphery of the hub. The liquid reservoir 31 is wound around the outer peripheral surface of the hub. Is in communication with. The upper case 1 is provided with three supply holes 35 for supplying the cleaning liquid above the liquid reservoirs 31 of the hubs 5 and 7, respectively. When a cleaning liquid such as alcohol is injected from the supply hole 35, the liquid enters the liquid reservoir 31 and then the cleaning liquid is supplied to the cleaning tape 9 through the slit 33, and a plurality of cleaning tapes wound using the capillary phenomenon are wound. Through each layer to wet each layer at certain intervals along the length of the tape. As a result, when the magnetic head enters the magnetic head insertion opening 15, the spring-biased lever 19 presses the cleaning tape 9 against the magnetic head, whereby the cleaning tape 9 alternates between the dry and wet states. While wiping, the well-known cleaning action can be achieved.

Next, to explain the part related to the features of the present invention, the cassette type cleaner of this embodiment is provided with means for cleaning a pinch roller. In FIGS. 1 and 3, a cleaning member 45 made of felt, foam, cloth, non-woven cloth, leather or the like is provided on the inner surfaces of the left side wall 33 and the right side wall 33 of the case, and one end of the cleaning member 45 is pinched. It faces the roller insertion slot 13. The cleaning member 45 is movably held by restriction plates 37 provided at regular intervals. Further, at the lower left corner and the lower right corner of the case, there are provided a feed roller 41 having a large number of protrusions 39 on the outer periphery and a cross groove 43 at the shaft end. It is pressed against the inner surface of the. As a result, the cleaning member 45 is fixed at a desired position, and the front surface of the tip end thereof can come into contact with the pinch roller penetrating the pinch roller insertion port, and a predetermined cleaning action can be performed.

As shown in FIGS. 3 to 6, a shaft hole 69 is formed on the lower surface side of the feed roller 41, and is fitted to a shaft 71 formed on the lower case 3. A shaft 67 is provided on the upper surface of the feed roller and fits in the shaft hole of the upper case 1. The cross groove 43 into which a driver or other operating tool can be inserted is formed at the end of the shaft 67.

[0012]

[Operation and effect of the device]

 Since the structure of the capstan cleaning means of the present invention is as described above, prior to cleaning, the cassette type cleaner is mounted on the cassette mounting portion of the tape recorder, and then the pinch roller is inserted into the pinch roller insertion hole 13. . As a result, the surface of the cleaning pad 45 exposed at the insertion opening 13 comes into contact with the pinch roller. In this way, predetermined cleaning is performed. When the feed roller 41 is rotated by the driver, the cleaning pad 45 is fed out by a desired amount so that the fresh surface can be brought into contact with the pinch roller. Also, the dirty part may be removed. As described above, in the present invention, the cleaning member can be renewed and the cleaning action can be maintained for a long period of time.
