In addition, also be provided with a pair of respectively with the above-mentioned the 1st and the 2nd the 1st download link 170,170 that is written into gear 150,160 mutual interlocks '.Above-mentioned the 1st download link 170,170 ' front end, will be respectively and the 2nd download link 172,172 ' link to each other, and above-mentioned the 2nd download link 172,172 ' front end, then link to each other with dump box 180,180 ' respectively.Above-mentioned dump box 180,180 ' will move according to the loading pass of host sectors, and in above-mentioned dump box 180,180 ', be respectively equipped with the tilt column 182,182 that guiding tape T uses ' and guidance device 184,184 '.
To the effect of tape loading device for magnetic recording player among the present invention with said structure characteristics be elaborated below.
At first, as shown in Figure 5, when magnetic tape cassette is loaded in the host sectors, above-mentioned tilt column 182,182 ' and guidance device 184,184 ' will promote tape T respectively by the driving of above-mentioned load motor 130, so that being moved to, it is written on the position.
The driving force of above-mentioned load motor 130 will send above-mentioned functions dish 135 to by above-mentioned driving reduction gearing 132 and gear row 133.As shown in Figure 6, above-mentioned functions dish 135 moves by the driving of above-mentioned load motor 130 to the right for being written into tape T.
By moving of above-mentioned functions dish 135, with above-mentioned functions dish 135 mutual meshing above-mentioned sector gears 140, will be along rotation counterclockwise.In addition,, will rotate the above-mentioned the 1st and be written into gear 150 by the rotation of above-mentioned sector gear 140, and with the above-mentioned the 1st rotation interlock that is written into gear 150, the above-mentioned the 2nd is written into gear 160 also will rotate simultaneously.
Shown in the left side synoptic diagram among Fig. 7, under the state of tape T unloading, the above-mentioned the 1st the 1st gear teeth 153 that is written into gear 150 will closely link to each other with the 1st gear teeth 145 of above-mentioned sector gear 140.In addition, if above-mentioned sector gear 140 does not rotate, the so above-mentioned the 1st is written into gear 150 will be for being written into tape, and can not rotate arbitrarily along clockwise direction.
Shown in the right side synoptic diagram of Fig. 7, by above-mentioned load motor 130, above-mentioned sector gear 140 will be for being written into tape T along rotation counterclockwise.At this moment, the 1st gear teeth 145 of above-mentioned sector gear 140 also will be along rotation counterclockwise.In view of the above, the 1st gear teeth 145 and the above-mentioned the 1st of above-mentioned sector gear 140 is written into the 1st gear teeth 153 mutual dislocation of gear 150 and closely is connected the 1st and is written on the starter receiver tooth 155 of gear 150.
At this moment, the 1st gear teeth 145 and the above-mentioned the 1st of above-mentioned sector gear 140 be written into gear 150 the 1st gear teeth 153 mutual dislocation operations and and the 155 close-connected operations of above-mentioned starter receiver tooth between visual interval, will become minimum.That is, the 1st gear teeth 145 of above-mentioned sector gear 140 closely is connected with the 1st starter receiver tooth 155 that is written into gear 150 when being written into the 1st gear teeth 153 mutual dislocation of gear 150 with the above-mentioned the 1st.
Under state like this, by the rotation of above-mentioned sector gear 140, the 1st gear teeth 145 of sector gear 140 will be benchmark with Fig. 7, promote the above-mentioned the 1st starter receiver tooth 155 that is written into gear 150 along clockwise direction.In addition, above-mentioned sector gear 140 will continue along rotation counterclockwise, and the connection gear device 152 that the driving gear trochus 144 of above-mentioned sector gear 140 and the above-mentioned the 1st is written into gear 150 will be meshing continuously also, so that the above-mentioned the 1st is written into gear 150 and rotates along clockwise direction.
In addition, by the above-mentioned the 1st and the 2nd rotation that is written into gear 150,160, drive respectively above-mentioned the 1st download link 170,170 ' and therewith above-mentioned the 2nd download link 172,172 of interlock ', and above-mentioned dump box 180,180 ' will be along loading pass, and position adjacent moves to the two ends of above-mentioned rotary head cylinder 109.By above-mentioned dump box 180,180 ' move, tape T also will be moved to and be written into the position.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
