Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape cartridge that prevents a subsequent tape to be wound onto a winding portion of a magnetic tape (hereinafter referred to as tape) from entering the winding position.

Conventionally, a case has a case consisting of a cover part and a base part, and a reel on which a magnetic tape is wound is rotatably supported approximately at the center of the base part in the case, and the magnetic tape is wound around the wound part of the case. A tape cartridge is known in which the tape is wound from the innermost side to the outermost side of the drawer winding section.

In such a tape cartridge, the reel rotates rapidly due to vibrations caused when it is attached to and removed from the player, stored in a storage case, or transported, and the tape pulled out from the innermost part of the winding section is Before the tape is wound to the outermost side of the winding part, the tape that follows the wound tape advances to the winding side and becomes largely slack, and a part of the tape becomes loose between the tape to be wound and the winding part. It may enter the winding position from the gap and become wedged between them. For this reason, there were problems such as not only the tape being damaged but also the tape becoming unable to run.

The present invention was developed in view of the above-mentioned problems, and has a case consisting of a cover part and a base part, and a reel around which magnetic tape is wound is rotatable approximately at the center of the base part inside the case. In the tape cartridge, which is pivotably supported on the tape cartridge so that the magnetic tape is pulled out from the innermost side of the winding part and wound onto the outermost side of the winding part, the magnetic tape to be wound on the outermost side of the winding part and The cover section is provided with a partition that extends outward in the radial direction of the reel from a position in contact with the outer periphery of the reel at least between the cover section and the winding section. By providing a slit in the partition wall perpendicular to its extending direction, a part of the partition wall can be easily bent and removed, and the outer diameter of the reel can be changed. It is characterized in that the length of the partition wall can be easily adjusted as required. Hereinafter, the present invention will be explained with reference to the drawings.

The drawing shows one embodiment of the present invention.
0 is a case in which an upper half (cover part) 10a and a lower half (base part) 10b are stacked on top of each other; 1;
Reference numerals 1, 12, and 13 indicate a plurality of openings formed in the front surface of the case 10, and the opening 11 has a capstan (not shown) provided on the player, and the openings 12, 1
Similarly, magnetic heads (not shown) are arranged at 3 so as to face each other during operation. 14 is case 1
A tape guide 15 is provided on one side of the inner front surface of the base portion 10b of 0, a pinch roller 15 is also rotatably provided on the other side, and 16 is a head pad mechanism. A reel 17 is rotatably supported approximately at the center of the base portion 10b inside the case 10, and a hub 17a is provided at the center. 18 is reel 1
This tape 18 is wound around the outer periphery of the hub 17a of No. 7, and this tape 18 is pulled out from the innermost side of the tape winding portion A through the inclined portion 19a of the guide plate 19 in an obliquely reversed state, and , travels along the openings 11, 12, 13 via the pinch roller 15, changes direction via the pole 20, and is wound onto the outermost side of the winding section A from the opposite side of the tape pull-out area. ing. Reference numeral 21 denotes a pole provided at a symmetrical position to the pole 20. The tape 18a to be wound may be wound on the outermost side of the winding portion A via the pole 21 as shown by the two-dot chain line in the figure.

Reference numeral 30 denotes a partition wall that is a feature of the present invention, and is located between the magnetic tape 18a to be wound on the outermost side of the winding section A and the winding section A and at least on the reel 17.
reel 17 from a position touching the outer peripheral edge 17b of
The cover portion 10a is provided so as to extend outward in the radial direction. Slits 31 and 32 are provided at a predetermined interval from the radially inner end 30a of the partition wall 30 toward the outside in the radial direction so as to be orthogonal to the extending direction of the partition wall 30.

According to the tape cartridge having the above-described configuration, in the normal operating state, the tape 18 is pulled out from the innermost side of the tape winding part A through the inclined part 19a of the guide plate 19 in an obliquely reversed state,
The tape runs along the openings 11, 12, 13 via the tape guide 14 and the pinch roller 15, changes direction via the pole 20, and is wound onto the outermost side of the winding part A from the opposite side of the tape pull-out area. It will be done. In addition, the reel 1
7 rotates rapidly, and before the tape 18 pulled out from the innermost side of the winding part A is wound onto the outermost side of the winding part A, the tape 18b following the tape 18a to be wound is When the tape 18b advances to the winding side and becomes slack as shown by the dashed line in the figure, the partition wall 30 prevents the following tape 18b from entering the winding position side of the preceding tape 18a. There is no fear that the following tape 18b will be sandwiched between the tape 18a to be wound on the winding part A and the winding part A and be damaged, or that the tape 18 will not be able to rotate. Furthermore, the partition wall 30
Since the inner end 30a in the radial direction is in contact with the outer peripheral edge 17b of the reel 17, it is possible to prevent the tape on the outer periphery of the winding portion A from loosening and falling from the top of the reel 17. Further, the partition wall 30 has slits 31 and 3 perpendicular to its extending direction.
2, a part of the partition wall 30 can be easily bent and removed, and therefore the length of the partition wall 30 can be easily adjusted according to the size of the outer diameter of the reel 17.

As explained above, according to the tape cartridge according to the present invention, the magnetic tape to be wound on the outermost side of the winding part and the winding part are located at least from a position in contact with the outer periphery of the reel to a diameter of the reel. Since the cover portion is provided with a partition wall extending outward in the direction,
The reel rotates rapidly due to vibrations caused when it is attached to and removed from the player, stored in a storage case, or transported, and the tape pulled out from the innermost part of the winding part is wound to the outermost part of the winding part. Even if the tape that follows the tape to be wound advances toward the winding side and slackens significantly before being wound, the succeeding tape is prevented from entering the winding position side of the preceding tape by the partition wall. Therefore, there is no possibility that the following tape will be damaged by being caught between the tape to be wound by the winding section and the winding section, or that the tape will not be able to rotate. Further, since the partition wall is provided to extend radially outward from the position where it contacts the outer periphery of the reel, even if the tape on the outer periphery of the winding section becomes loose, the radial inner end of the partition wall prevents it from falling off the reel. can. Furthermore, since the partition wall is provided with a slit perpendicular to its extending direction, a portion of the partition wall can be easily bent and removed, and the length of the partition wall can be adjusted depending on the outer diameter of the reel. It has the advantage of being easy to perform.
