Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape cassette that is most suitable for application to recording and reproducing devices such as video tape recorders and other various information processing devices.

As is well known, tape cassettes for video tape recorders and the like have traditionally had a front opening at the front of the cassette housing in which tape is wound around a pair of left and right tape reels.
A bottom opening connected to the front opening is provided on the bottom of the cassette housing, a tape is stretched along the front opening, and the front side of the stretched tape is covered with a front lid. When the tape cassette is loaded into a video tape recorder or the like, the front cover is opened to open the front opening, and the tape loading means is inserted into the inside (rear side) of the tape from the bottom opening. The tape is pulled out of the cassette housing from the front opening by the loading means and loaded onto the tape running path.

By the way, in conventional tape cassettes of this kind, the pair of left and right tape guides for passing the tape along the front opening are constructed of expensive metal pipes, resulting in high component costs.

Furthermore, in the past, when assembling the cassette housing by fitting the upper and lower halves together from above and below, the metal pipes were sandwiched and fixed from above and below, making assembly of the tape cassette extremely troublesome.

In particular, with this type of tape cassette, normally both reels are inserted onto the lower half from above and positioned, and after the tape is stretched along the front opening, the upper half is inserted together with the front lid onto the lower half. When assembled, the tape is fitted and screwed together, but if there is any slack in the tape, it is likely to be damaged by the front cover or the like. Therefore, it is necessary to fit the upper half onto the lower half while supporting the tape stretched along the front opening under tension, but with conventional metal pipes, the upper and lower halves are fitted in a predetermined state. It is fixed only when the metal pipe is placed on the lower half (
In state B) before fitting the upper half onto the lower half,
This metal pipe was unstable and easily fell off if it wobbled, and it was difficult to support it with tension on the tape. Therefore, conventionally, when fitting the upper half onto the lower half together with the front cover, the tape tends to become loose, and not only is it easy to damage the tape with the front cover, but also it is difficult to prevent the tape from becoming loose. It was extremely troublesome to carefully fit the upper half onto the lower half, and at the same time to sandwich and fix the metal pipe between the upper and lower halves.

The present invention was invented to correct the above-mentioned defects, and is a tape cassette that has low parts cost, can be easily assembled without damaging the tape, and has a sufficient tape guide. The object of the present invention is to provide a tape cassette that can have a high strength.

A pair of guided pins 41 are provided at both left and right ends of the rear lid 37, as shown in FIG. 4 and FIGS. 7 to 9.

These guided pins 41 are attached to the tips of a pair of brackets 42 that protrude from the approximate center of both left and right ends of the rear lid 37 toward the side opposite to the front lid 20, and the guide pins 41 on both sleeves are attached to the outside. It is projected horizontally towards the on the other hand,
Both left and right ends of the partition wall 17 integrally molded with the lower half 3 are formed into a pair of left and right inner walls 43 that face each other inwardly, and a third inner wall 43 is formed on the inner surface of these side inner walls 43.
As shown in the drawings and FIGS. 7 to 9, a pair of guide grooves 44 facing the bottom opening 16 are provided. These guide grooves 44 are formed diagonally from the upper rear side of the side inner wall 43 (upper left in FIGS. 7 to 9) to the lower front side (lower right in the figures), and are approximately at the vertical center of both guide grooves 44. The portion 45 is located slightly closer to the fulcrum pin 22. Therefore, both guide grooves 44
The center portion 45 is closest to the fulcrum pin 22 and has a dogleg shape. The double wave guide pin 41 is inserted into both guide grooves 44, and the sleeve guide pin 41 is guided by both guide grooves 44 when the front cover 20 is rotated.

As shown in FIGS. 7 to 9, the portions of both guide grooves 44 below the upper and lower substantially central portions 45 are designed to allow the sleeve guide pins 41 to gradually approach both fulcrum pins 22 as they rise. The guide portion 44a is formed in a curved shape, and the portion above the upper and lower substantially central portions 45 is curved to gradually move the sleeve guide pin 41 away from the support pins 22 as it rises. The guide portion 44b is formed in a manner similar to that shown in FIG.

In the above, on the bottom wall 10 of the lower half 3, the partition wall 17, the pair of left and right tape guides 18, 19, and the pair of left and right inner walls 43 are integrally molded and connected to each other. A pair of left and right guide grooves 44 are formed on the inner surfaces (opposing surfaces) of the pair of left and right inner walls 43 . Further, a pair of left and right tape passages 46 are formed between the pair of left and right inner walls 43 and the outer wall 23, which communicate between the pair of left and right tape reels 7.8 and both left and right ends of the front opening 15. The tape 9 then passes through both tape channels 46 and is guided by both tape guides 18, 19 to the front opening 15.
It spans along the

Incidentally, if both tape guides 18 and 19 are integrally molded and provided on the bottom wall 10 of the lower half 3, the tape cassette can be easily assembled.

That is, when assembling the tape cassette, first, as shown in FIG. 3, both tape reels 7.8 are inserted onto the bottom wall 10 of the lower half 3 from above and fitted into the reel fitting holes 11.12. After aligning and positioning, the tape 9 is stretched along both tape passages 46 and the front opening 15. At this time, simply insert the tape 9 into both tape guides 18.19 from above and tension it.
Since the tape 9 can be easily supported, the tape 9 can be easily assembled.

Next, after this, the front cover 20, the rear cover 37, etc. are attached to the upper half 2, and the side covers 20, 37 are rotated upwardly of the upper half 2 as shown in FIG. Half 2

can be kept taut between both tape guides 18 and 19, so when the tape 9 is sandwiched between the side lids 20 and 37 from the front and back, the tape 9 is not damaged by the side lids 20 and 37. Therefore, the side cover 20.37 can be easily assembled.

Next, on the front edges of both outer walls 23 of the lower half 3, as shown in FIG.
As shown in FIGS. 3 and 10 to 11, a pair of lock claws 48 are integrally molded. Both lock claws 48 are attached to the tips of a pair of leaf spring parts 49 that protrude from the upper ends of both front edges toward the lower ends.
Both lock pawls 48 are elastically movable in the left-right direction in FIGS. 10 to 12. On the other hand, a pair of lock holes 5 are provided at the lower end of both left and right ends of the front cover 20, as shown in FIG.
0 is set. When the front lid 20 is closed, both locking claws 48 are inserted into the double-ended openings 5 as shown in FIG.
0 and the front cover 20 is locked. The plate spring portions 49 have an arc shape centered on the pin holes 24, so that opening and closing operations of the front cover 20 are not hindered. A pair of slits 51 are provided at the lower end edge of the front lid 20 below the double-ended hook holes 50. These slits 51 are positioned in front of the tips of the leaf spring portions 49, as shown in FIG. 10, when the front cover 20 is completely closed. When the tape cassette is attached to a cassette holder etc., a pair of protrusions 52 provided on the cassette holder etc. are inserted through both slits 51 as shown in FIG.
9, both locking claws 48 are inserted into the double-ended openings 50.
It is configured to be removed from the In addition, both lock claws 4
8 is provided with an inclined portion 53 as shown in FIGS. 11 and 12, and both slits 51 are provided when the front lid 20 is closed.
The inner wall of the drawing board spring part 49 presses against these inclined parts 53, so that the tip of the drawing board spring part 49 bends to the left as in the case shown in FIG. That is, immediately after this, both the locking claws 48 and the double-ended locking holes 50 are click-engaged by the restoring force of both the plate spring portions 49.

Inside the cassette housing 1, as shown in FIG. 3, a reel lock pawl 57 is provided between the tape reels 7 and 80.

The reel lock pawl 57 is molded from synthetic resin, and as shown in FIG. 1st
and a V-shaped leaf spring portion 60 provided on the rear side (lower side in FIG. 13) of the second plate portion. Pointed tree-like claw portions 61 are provided at both left and right ends of the second plate portion 59. On the other hand, tape reel 7.8
Each lower flange 56 has a thirteenth
As shown in the drawings and FIG. 14, serrated teeth 62 are provided, and the pair of claws 61 of the reel lock claw 57 engages with both teeth 62 to rotate the tape reel 7.8 in the tape loosening direction. can be locked. That is, the reel lock pawl 57 is located inside the cassette housing 1, and the elasticity of the leaf spring portion 60 causes both pawl portions 61 to move in the front-back direction (the first
3), and under normal conditions (when the tape cassette is not attached), both claws 61 are pressed against the pair of teeth 62 by the spring force of the temporary spring section 60, and are engaged with each other. -ing A pair of notch holes 63 and 64 are provided in the second plate part 59 and the leaf spring part 60, respectively, so that the second plate part 59 and the temporary spring part 60 have appropriate elasticity. .

To install the reel lock claw 57 into the cassette housing 1, as shown in FIG.
5 only is shown), and when the upper and lower halves are fitted together from above and below, the reel lock claws 57 are installed or incorporated into the respective claw attachment notches 65. . As shown by the dashed line in FIG. 13, both claws 61 protrude toward the tape reel 7.8 from a pair of left and right openings 66 of the claw attachment notch 65 of the lower half 3.

An inclined surface 67 is formed at the center of the second plate portion 59 of the reel lock pawl 57, as shown in FIGS. 14 and 15. On the other hand, a bottle hole 68 is provided below the inclined surface 67 in the bottom wall of the claw attachment notch 65 . and,
When the tape cassette is installed, a lock release pin 69 is inserted through the pin hole 68 in the direction of the arrow as shown in FIG. 15, so that the tip of the lock release pin 69 presses against the inclined surface 67. That is, when the tape cassette is installed, the first and second plate parts 58 and 59 move together with both claw parts 61 in the direction of arrow C in FIG. 15, and the tape reel 7.
8 is configured to be unlocked.

The tape cassette is constructed as described above, and normally the tape 9 is stretched along the front opening 15 as shown in FIG. It is covered by a rear lid 37. That is, the tape 9 is protected in the tape chamber 40 while being sandwiched between the front cover 20, the inner plate 35, and the rear cover 37 from the front and rear. In addition, in this closed state, both locking claws 48 fit into both openings 50 and the front lid 20 is closed, as shown in FIG.
is locked to prevent the front cover 20 from being opened inadvertently. Note that at this time, the notch 31 is
Covered by 9.

On the other hand, when the tape cassette is attached to the video tape recorder main body, the front M20 and the rear lid 37 are rotated above the upper half 2 as shown in FIG. 9, and the front and back sides of the tape 9 are opened. That is, for example, when a tape cassette is inserted into a cassette holder of a video tape recorder main body, a pair of left and right protrusions 52 provided on the cassette holder, etc., move away from both slits 51 in the direction of arrow a, as shown in FIG. , and both protrusions 52 press the tips of both leaf spring parts 49 . As a result, both plate spring parts 49 are bent to the left in FIG. 11 against the spring force, and both lock claws 48
are removed from the double-end hook holes 50, and the front cover 20 is unlocked.

Next, when the tape cassette is moved downward in FIG. 11 and installed in the cassette mounting position, the front cover 20 is pushed up by a projection provided on the video tape recorder main body (not shown), as shown in FIG. 12. The front lid 20 is rotated counterclockwise while being twisted against the elasticity of the torsion bar 26, and the front lid 20 is opened widely above the upper half 2. In conjunction with the front cover 20, the rear cover 37 is also inserted through the notch 31 of the upper half 2 and opened wide above the upper wall 32 of the upper half 2, as shown in FIG.

However, at this time, the initial stage of rotation when opening the rear cover 37 (
At the end of the rotation when the lid is closed, as shown in FIG. This will lead to the upper and lower substantially central portions 45. Both guide portions 44a support both wave guide bins 41 and both fulcrum bins 2.
2, the rear cover 37 is not moved upward by the front cover 20, but is rotated clockwise in FIG. 8 about both fulcrum pins 38 of the front cover 2o. Therefore, at the initial stage of rotation when opening the rear cover 137, the lower end 39 of the rear cover 37 is rotated upward while being separated from the rear of the tape 9. Note that the lower end portion 34 of the front cover 20, which is rotated counterclockwise in FIG. 8, is also rotated upward while being separated toward the front side of the tape 9. Therefore, when opening the lid, the front lid 2
At the beginning of the rotation of the 0 and rear lid 37 (the same applies at the end of the rotation when the lid is closed), there is no possibility that these lower ends 34 and 39 will accidentally catch the tape 9 and damage it.

In addition, at the end of the rotation of the rear lid 37 when the lid is opened, as shown in FIG. will be done. In order to guide the wave guide pins 41 gradually away from the support pins 22, the guide portions 44b guide the support pins 38 of the front cover 20 while the rear cover 37 is not moved upward by the front cover 20. Rotate counterclockwise around the center in Figure 9.

When the front lid 20 is completely opened, the rear lid 37 passes through the notch 31 of the upper half 2 and becomes horizontal on the upper wall 32 of the upper half 2, as shown in FIG. The portion 39 contacts the inner surface of the lower end portion 34 of the front lid 20. Therefore, a wide space is secured behind the tape 9, and there is no problem such as collision between the tape loading means (not shown) inserted through the bottom opening 16 and the rear lid 37. Furthermore, when the tape 9 is subsequently pulled out of the cassette housing 1 from the front opening 15 by the tape loading means, there is no problem in which the tape 9 is accidentally caught on the rear lid 37 and damaged. Since the rear cover 37 is opened and closed within the bottom opening 16, the space for mounting the tape cassette within the main body of the video tape recorder can be minimized to the necessary minimum.

On the other hand, the upper lid 29 slides rearward on the upper wall 32 of the upper half 2 as the front lid 20 rotates upward. Therefore, the left and right ends 30 of the torsion bar 26 do not rotate, but only the center part 28 is twisted by the upper end 25 of the front cover 20, and the upper cover 29 is rotated counterclockwise in FIG. Dynamically biasing elastic energy is stored. Therefore, the front cover 20 is biased clockwise in FIG. 9 by the reaction force acting on the top cover 29, and when the tape cassette is removed from the main body of the video tape recorder, the front cover 20 is pushed by the force of the torsion bar 26. Closed.

Furthermore, when the tape cassette is moved downward, the lock release pin 69 provided on the main body of the video tape recorder is inserted into the cassette housing 1 through the pin hole 68 as shown in FIG. The surface 67 is subjected to volatile pressure. Therefore, the first and second plate portions 58 and 59 are connected to both claw portions 61.
At the same time, the tape reel 7.8 moves to the left in FIG. 15, and the claws 61 disengage the teeth 62 of the tape reel 7.8, releasing the tape reel 7.8 from its locked state.

When the tape cassette is removed from the main body of the video tape recorder, the operating conditions of the front cover 20, inner cover 37, upper cover 29 and reel lock pawl 57 are completely reversed to those described above. The tape 9 stretched along the front opening 15 is protected in the tape chamber 40 while being sandwiched between the front cover 20, the inner plate 35, and the rear cover 37 again from the front and back.

Therefore, when the tape cassette is not in use, the rear cover 3
7 protects the rear side of the tape 9, so the bottom opening 1
Dust and the like that have entered the cassette housing from the cassette case 6 will not adhere to the tape 9, and the tape 9 will not be easily damaged by fingers or the like inserted into the bottom opening 16.

Note that the notch 31 provided in the upper wall 32 of the upper half 2 in order to allow the rear lid 37 to rotate significantly upwards of the upper half 2 when the lid is opened as described above is in the closed state as shown in FIG. It is covered with an upper lid 29. Therefore, the intrusion and insertion of dust, fingers, etc. into the cassette housing 1 through the notch 31 is reliably prevented, and the sealing effect of the cassette housing 1 is extremely high. Furthermore, since the notch 31 is covered and hidden by the upper lid 29, the appearance of the tape cassette is also very good. Moreover, at this time, as shown in FIG. 7, the slope or substantially stepped portion 29a provided at the rear end edge of the upper lid 29 is brought into close contact with the slope or approximately stepped portion 31a provided at the rear end edge of the notch 31. Therefore, the sealing performance of the notch 31 by the upper cover 29 is very high, and in particular, it is possible to reliably prevent dust and the like from entering into the cassette housing 1 through the notch 31. .

Furthermore, when the tape cassette is not in use, the tape reel 7.8 is locked by the reel lock claw 57, so that the tape 6 stretched along the front opening I5 will not loosen due to vibration or the like. Inconveniences such as the tape loading means colliding with the tape 9 when inserting the loading means do not occur.

However, the tape 9 includes the front lid 20, the inner plate 35, and the rear lid 37.
Because it is sandwiched and protected from the front and back by
Even if the reel lock pawl 57 is not provided, the tape 9 will not loosen to the extent that it poses a practical problem. Furthermore, if appropriate cushioning materials are attached to the inner wall surfaces of the front lid 20 and rear lid 37, and these cushioning materials are lightly pressed on the front and back of the tape 9, the tape 9 will not loosen at all even without the reel lock claw 57. There will be no.

Although the embodiments of the present invention have been described above, the present invention is not limited to the structure shown in the above embodiments, and various modifications can be made.

For example, in the above embodiment, the tape 9 is attached to the inner plate 35 and the rear cover 37.
The inner plate 35 and the rear cover 37 are integrated, and the upper end of the inner plate 35 and the upper end of the front M20 are hinged to form an integrated inner plate 35 and rear cover 37. It may be opened and closed.

As described above, the present invention has a pair of left and right tape guides for passing the tape along the front opening of the cassette casing, which are integrally molded into the cassette casing. There is no need to use it at all,
Parts costs can be reduced. Also, since metal pipes are not used, it is extremely easy to assemble the tape cassette by fitting the upper and lower halves together from above.

Furthermore, if the tape guide is integrally molded onto the lower half of the cassette housing, when assembling the tape cassette, both reels can be inserted and positioned onto the lower half from above, and the tape can be inserted upward into the tape guide on the lower half. The tape can be easily and stably supported in a tensioned state by simply inserting it from the bottom and tensioning it, making it easy to assemble the tape inside the lower half. Furthermore, since the tape can be kept taut and supported between both tape guides, there is no slack in the tape when fitting the upper half onto the lower half together with the front cover. Moreover, the upper and lower halves can be assembled very easily without damaging the tape with the front cover, etc. Therefore, the tape cassette can be assembled extremely safely and extremely easily.

In particular, the present invention provides a partition wall that partitions the inside of the cassette casing between the tape reel side and the bottom opening side, and a pair of left and right tape guides are connected to both left and right ends of the partition wall. Since the partition walls are integrally molded with the cassette housing so that the pair of left and right tape guides can be firmly supported by the partition walls, the tape guides can have sufficient strength. Therefore, even if a large load is applied to the tape guide when guiding the tape, the tape guide will not bend or tilt, and the tape can be guided with high precision at all times. This prevents deterioration of recording and reproducing characteristics due to deterioration of travel guidance accuracy.
