Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a small tape cartridge adapter that allows a small tape cartridge to be used by being loaded into a magnetic recording device for a large tape cartridge.

This type of adapter has a storage chamber in the adapter body that has substantially the same external shape as a large tape cartridge, and a small tape cartridge is inserted into this storage chamber from above and stored. The tape is pulled out to the front side of the adapter body and then loaded into the magnetic recording device.

Regarding such an adapter, the present applicant previously proposed a structure in which an opening/closing lid that closes the upper surface of the opening of the storage chamber is rotatably pivoted to the adapter body, but this idea goes further and allows the opening/closing lid to close the upper surface of the opening of the storage chamber. When the lid is closed against the top of the opening, the lid can be automatically locked, allowing one-handed operation to close the lid and preventing the lid from opening accidentally.

Hereinafter, embodiments of this invention will be described based on the drawings. The illustrated adapter 1 is designed to allow a small-sized video tape cartridge 2 to be loaded into a video deck for a normal large-sized tape cartridge.

(1) Structure of a small tape cartridge In Figs. 1 and 2, the small tape cartridge 2 functions independently, and the upper and lower plastic cases 3a and 3b are tapped together to form lids. Tape reels 5 and 6 with flanges on both sides, on which tape 4 is wound, are rotatably mounted on the left and right sides of the main body case 3, which is connected with screws, etc.
There are tape guide members 7 on the left and right front of the main body case 3.

is led out from the left delivery reel 5 to the front of the case and taken up on the right take-up reel 6. However, the tape reel 5 on the output side is installed on the drive shaft insertion hole provided in the bottom wall of the case with a certain amount of free movement in the radial direction, and the tape reel 6 on the take-up side is installed around the vertical fixed shaft 9. It rotates while being supported in a fixed position, and a gear portion 11 formed on the outer periphery of the lower flange 10 is exposed laterally outwardly through a notch 13 formed across the bottom wall and right side wall 12 of the main body case 3. are doing. A transparent window 15 is formed on the left side of the upper case 3a for visually checking the amount of tape wound on the output tape reel 5 from the outside.

The main body case 3 is provided with a front cover 16 for closing the front side of the main body case 3 and protecting the tape 4 when not in use. In the front lid 16, connecting pieces 18, 18 are extended rearward from both left and right ends of the front plate 17, and both connecting pieces 18, 18 are attached to the left and right side walls 12, 1 of the main body case 3.
A U-shaped spring member 19 is mounted on the right side wall 12, and the front cover 16 is rotated about 70 degrees from the open or closed position. When it is in the closed position with the opening angle set as the dead center, it is held in the closed position, and when it is in the upward open position at 90 degrees forward, it is held in the open position.

(2) Basic structure of the adapter In Figures 1 and 2, the proposed adapter 1
At least, the external shape of the adapter body 20 is formed to have substantially the same specifications as a large tape cartridge, as shown in the figure, a VHS type tape cartridge,
When loaded into a magnetic recording device for a VHS type tape cartridge, the magnetic recording device operates without any trouble.

The adapter main body 20 is made up of upper and lower plastic cases 20a and 20b that are joined together with tapping screws, etc., and insertion holes 22 and 23 into which the drive shaft of the magnetic recording device is inserted are transparent on the left and right sides of the bottom wall 21. A front cover 24, which closes the front surface of the adapter body 20, is pivotally attached to the adapter body 20 so as to be rotatable in opening and closing, and is always biased by a spring member 25 to a closed position.

A storage chamber 26 into which the small tape cartridge 2 is inserted and removed from above is defined at the left side of the adapter body 20 in the figure, and an opening/closing lid 27 that closes the top surface of the opening of the storage chamber 26 to the adapter body 20. is rotatably pivoted.

Inside the adapter body 20, a pair of left and right tape drawer members 29 and 30 are installed in a vertical position so as to be freely movable between a retracted position and a front drawer position. At 31, it is operated to switch between two positions: a retracted position and a pulled-out position. The tape pull-out mechanism 31 includes left and right link mechanisms 32 and 33 provided in the adapter body 20, and an operation member 34 that moves the left and right tape pull-out members 29 and 30 via these link mechanisms 32 and 33. swings around the fulcrum 35 on the right side of the adapter body 20, and the knob 36 of the operating member 34
It faces the outside through a slit 39 provided in the rear wall 37 of the housing.

(3) Basic operation of the adapter Open the opening/closing lid 27, store the small tape cartridge 2 in the storage chamber 26 in a predetermined direction, and then open the opening/closing lid 27.
When it is closed, the front lid 16 of the small tape cartridge 2 automatically opens in a manner described later, and the tape 4 becomes ready to be drawn out from the small tape cartridge 2. FIG. 3 shows the state immediately after the small tape cartridge 2 has been stored. In this state, the front lid 16 is open and the tape 4 is stretched between the front left and right tape guide members 7. , the tape drawer members 29 and 30 are waiting at retracted positions on the front left and right sides of the storage chamber 26, and when the small tape cartridge 2 is inserted into the storage chamber 26 from above,
The tape pull-out members 29 and 30 relatively enter the recesses 40 and 41 on the left and right front ends of the small tape cartridge 2 from below and engage inside the tape 4 stretched between the tape guide members 7 and 7. If the operating member 34 is swung clockwise from this state,
As shown in FIG. 4, the left and right tape drawer members 2
9 and 30 are moved via link mechanisms 32 and 33 to receiving members 42 and 43 fixed at positions near the left and right corners of the front end inside the adapter body 20, and the tape 4 is pulled out to the drawer position on the front side of the adapter body 20. . This tape draw-out position corresponds to the position where the front left and right tape guide members in a standard large tape cartridge should be, and the tape is set in the same state as in the large tape cartridge.

(4) Driving mechanism for the tape reel of a small tape cartridge using a magnetic recording device Above the drive shaft insertion hole 23 on the right side in the adapter body 20, there is a hub hole for the tape reel of a large tape cartridge as shown in FIG. A gear portion 11 is formed on the outer periphery of the lower flange 10 of the take-up side tape reel 6 of the small tape cartridge 2, and a drive gear 46 having a hub hole 45 substantially the same as that of the drive gear 46 is mounted so as to be freely movable in the radial direction. An idle gear 47 having upper and lower gear portions 47a and 47b is arranged between the drive gear 46 and the upper gear portion 47a of the idle gear 47 to freely thrust to the drive gear 46, and the lower gear portion 47b to the drive gear 46. They are respectively engaged with the gear portions 11 of the tape reel 6 on the take-up side.

The idle gear 47 is suspended from the lower side of a movable bracket 49 attached to the inner surface of the upper case of the adapter body 20 via a support shaft 48 so as to be able to move up and down within a certain range, and is biased upward by a compression coil spring 50. There is. Therefore, the storage chamber 26 of the adapter body 20
When the small tape cartridge 2 is inserted from above, even if the reel gear part 11 does not mesh well with the lower gear part 47b of the idle gear 47, the idle gear 47 temporarily escapes downward against the spring 50. When the meshing phase matches when the idle gear 47 starts driving, the idle gear 47 is automatically pulled up and becomes in a normal meshing state.

In FIGS. 3 and 4, bracket 49
is supported by the upper case 20a through engagement with a pin 51 and an elongated hole 52 so as to be rotatable within a certain angle range around the axis of the take-up tape reel 6, and is connected to the drive gear by a tension spring 53. 46 and reel gear part 1
1 and is urged to move in a wedge-shaped manner. Therefore, the idle gear 47 always meshes with the reel gear portion 11 and closely follows the free movement of the drive gear 46, so that the idle gear 47 always meshes with the gear 46 while absorbing play.

Therefore, when the tape 4 is pulled out and set on the front side of the adapter body 20 in the manner described above, and the adapter 1 is pushed into the magnetic recording device and loaded, the drive shaft on the magnetic recording device side touches the bottom wall 21 of the adapter body 20.

It is formed into a cross-sectional shape having an inclined guide surface 57 and a vertical surface 58 that continues to the inclined guide surface 57 and reaches the bottom wall 21. A gap that is set lower than the upper end of the tape cartridge 2 and that is sufficient to allow a fingertip to enter between the vertical downward surface 60 extending from the upper surface 59 of the adapter body 20 to the stepped surface 56 and the small tape cartridge 2. form g. Guide ribs 61 extending from the bottom wall 21 to the level of the stepped surface 56 are provided at rearward positions on the inner wall surfaces of the left and right side walls 55, respectively.

In such a case, as shown in FIG. 2, insert the small tape cartridge 2 from above into the storage chamber 26 with its front and back orientation aligned with that of the adapter body 20, and insert the small tape cartridge 2 into the storage chamber 26 from above on the rearward outer surface of the left and right side walls 12 of the small tape cartridge 2. The recessed vertical grooves 62 are guided and fitted into the guide ribs 61, respectively. When the small tape cartridge 2 is stored in the storage chamber 26, the left and right horizontal side walls 12 of the small tape cartridge 2 are received and supported by the vertical surface 58, thereby positioning the small tape cartridge 2 in the left and right direction. By fitting with 61, positioning in the front-back direction is performed. Therefore, the tape reel 5 on the output side of the small tape cartridge 2 stored in the storage chamber 26 is connected to the adapter body 20.
It fits concentrically on the drive shaft insertion hole 22 of. In addition, the inner wall surface of the left and right side walls 55 of the storage chamber 26 has a stepped surface 56 and an inclined guide surface 57 at the upper end, and a finger insertion gap g.

9, the small tape cartridge 2 can be easily picked out from the storage chamber 26 by inserting a fingertip into the gap g.

(6) Opening/closing lid of the storage chamber When the opening/closing lid 27 is in the closed state, the protruding side pieces 63, 63 on the left and right sides of the front end are pivotally connected to pivot about pivots 64, 64 so as to be able to open and close freely, and the opening/closing lid 27 is fitted onto one of the pivots 64. The helical spring 65 rotates and urges the opening position, and as shown in FIG. The angle (approximately 115°) is regulated.

The inner surface of the opening/closing lid 27 is provided with reinforcing ribs 66 , 66 protruding from the left and right ends running in the front-rear direction. The reinforcing ribs 66 act as guides when the upper surface of the storage chamber 26 is closed, and after the reinforcing ribs 66 are closed, the lower end surfaces of the reinforcing ribs 66 are received and supported by the stepped surfaces 56. Further, near the left and right ends of the inner surface of the opening/closing lid 27, there are plate springs 6.
7 and 67 are fixed, and when the small tape cartridge 2 is stored in the storage chamber 26 and the opening/closing lid 27 is closed, the leaf springs 67 and 67 elastically press and support the top surface of the small tape cartridge 2. .

The top surface of the opening/closing lid 27 is flush with the top surface 59 of the adapter body 20 in the closed state. In such a case, when the adapter 1 is pushed into the magnetic recording device in a horizontal position and loaded, the reference surface (usually four corners) on the bottom of the adapter body 20 is received and supported by the magnetic recording device, and the adapter body 20 opens and closes accordingly. Several locations on the top surface 59 of the adapter body 20, including the top surface of the lid 27, are held down by the magnetic recording device to prevent the adapter body 20 from wobbling. Note that the opening/closing lid 27 has the transparent window 1
A transparent window 69 for visual confirmation of the tape winding amount is formed corresponding to the number 5.

(7) Opening/closing means for the front lid of a small tape cartridge An engaging element 70 extends forward from the pivot 64 from near one pivot joint of the opening/closing lid 27 in the closed state of the opening/closing lid 27. Insert the small tape cartridge 2 into the storage chamber 26 with the cartridge opened.
As shown in FIG. The engaging claw 70a at the end engages. In this case, when the opening/closing lid 27 is closed against the upper surface of the storage chamber 26 against the helical spring 65, the front lid 16 automatically engages the engaging claw 70 of the engaging element 70.
a, and when the above-mentioned opening angle is exceeded, the front lid 16 automatically assumes an open position due to the spring member 19, and when the opening/closing lid 27 is closed, the engaging claw 70a serves as a support and absorbs the external force applied by a finger or the like to the front lid 16, thereby maintaining the front lid 16 in an open position.

Next, when removing the small tape cartridge 2 from the storage chamber 26, the front edge 27a of the opening/closing lid 27 is removed.
is in contact with the front lid 16 as shown in FIG.
is pressed downward, and the front cover 16 is automatically closed.

The front cover 16 of the small tape cartridge 2 in the illustrated example is designed to be able to close when it is in the closed position using a predetermined opening angle as a fulcrum; The engaging element 70 may be biased, and in that case, the engaging element 70 may be a biased element.
When the front cover 6 is in the open position, it is received and supported so that it does not close, and the front cover 16 closes in conjunction with the opening operation of the opening/closing cover 27.

(8) Fixing means for the small tape cartridge in the adapter storage chamber When the small tape cartridge 2 is stored and the adapter 1 is loaded into the magnetic recording device, one drive shaft on the magnetic recording device side is attached to the bottom of the adapter body 20. wall 2
The tape reel 5 is fitted into the hub hole of the tape reel 5 on the output side of the small tape cartridge 2 through the drive shaft insertion hole 22 provided transparently in the tape cartridge 1, and the tape reel 5 is pushed up.
At that time, the small tape cartridge 2 is
It is necessary to prevent it from rising within 5.

To this end, as shown in FIGS. 3 and 4, a pin 74 is erected on the intermediate link 73 of the ring mechanism 32 for moving the left tape pull-out member 29, and the proximal end of the lock arm 75 is attached to the inner surface of the upper case 20a of the adapter body 20. the two prongs of the lock arm 75 are connected to the pin 74;
A lock piece 76 is provided continuously from the base end of the lock arm 75. In the state before the operation member 34 operates to draw out the tape, the lock piece 7 is locked as shown in FIG.
6 does not face the storage chamber 26, but as the intermediate link 73 slides to the left as the tape is pulled out, the lock piece 76 moves into the storage chamber 26 as shown in FIG. A locking piece 76 engages in a semicircular recess 79 formed on the outer surface of the rear wall 77 of the cartridge 2, thereby fixing the small tape cartridge 2.

(9) Closing lid locking means for the opening/closing lid The opening/closing lid 27, which is rotatably biased to the open position by the helical spring 65, is locked to prevent it from opening in the closed state.

That is, press engagement pieces 80 are provided on the left and right inner surfaces of the rear end of the opening/closing lid 27 to protrude downward, and the press engagement pieces 8
The lower surface of the tip of the 0 is formed as an inclined surface 81, and the upper surface is formed as an engaging surface 82.

6, 7, and 11, an opening 83 is provided in a part of the adapter body 20 near the rear end of the upper case 20a, and a sliding operation knob 84 is inserted into the opening 83. The top surface is the adapter body 20
A plate-shaped lid lock 85 is fitted and supported so as to be slidable in the left and right directions so as to be substantially flush with the upper surface 59, and is integrally connected to the knob 84 and movable horizontally in the left and right directions within the adapter body 20. It has been done.

The lid locking device 85 has a spring holder 86 at the left end,
A spring member 88, which is a compression coil spring, is interposed between the spring receiving rod 86 and a spring receiving member 87 on the adapter body side, and is constantly urged to move in the right direction. In addition, claw-shaped engagement pieces 89 are located on the left and right front ends of the lid locking tool 85.
89 protrudes toward the storage chamber 26, and the upper right end side of each engaging piece 89 is formed into an inclined surface 90.

A locking portion 91 is protrudingly provided on the underside of the lid locking device 85, and a stopper 92 that abuts against the locking portion 91 is provided on the locking arm 75.

In such a case, when the opening/closing lid 27 is open,
That is, before the small tape cartridge 2 is inserted into the storage chamber 26, the lid lock 85 is biased to move rightward as shown in FIG. From this state, the small tape cartridge 2 is placed in the storage chamber 26.
When the opening/closing lid 27 is completely closed against the upper surface of the opening of the storage chamber 26 against the spring 65, the inclined surface 81 of each pressing engagement piece 80 is locked by the downward force applied to the opening/closing lid 27. abuts against the inclined surface 90 of 85;
The lid locking tool 85 itself is pushed to the left side against the spring member 88 to the unlocked position, and the pressing engagement pieces 80 go over each of the engaging pieces 89 of the lid locking tool 85 and wrap downward, and then When the lid locking device 85 is automatically returned to the right side by the spring member 88,
The engagement surface 82 of each pressing engagement piece 80 engages with the lower surface of each engagement piece 89 in a manner that prevents it from coming off, and the opening/closing lid 27 is thereby locked in the closed position with one touch.

When the tape drawer members 29 and 30 are pulled forward from this state, the intermediate link 73 of the link mechanism 32 moves to the left as described above, and the lock arm 75 rotates to release the stopper 92 provided thereon. As shown in FIG. 13, the lid locking tool 85 is rotated around and locked into the locking part 91 on the side of the lid locking tool 85, thereby preventing the lid locking tool 85 itself from moving in the unlocking direction. In other words, the opening/closing lid 27 cannot be opened using the operating knob 84 after the tape is pulled out. Therefore, after the tape drawer operation, the opening/closing lid 27 is opened by mistake, and the front lid 16 is opened in conjunction with this.
When the front cover 16 is closed, damage to the tape 4 being drawn out is reliably prevented.

When the operating member 34 returns the tape drawer members 29 and 30 from the front drawer position to the retracted position via the link mechanisms 32 and 33, the stopper 92 is disengaged from the locking portion 91. To open the opening/closing lid 27 under this condition, the operating knob 84 is slid to the left with a finger to move the lid locking tool 85 to the unlocked position. Then, the pressing engagement piece 80 and the engagement piece 89 are disengaged, and the opening/closing lid 27 is automatically opened by the biasing force of the spring 65.

(10) Locking means for the tape drawer mechanism using the opening/closing lid In FIGS. 14 to 16, a vertical shaft 94 is provided upright at the rear part of the storage chamber 26 in the adapter body 20, and a boss of a locking tool 95 is attached to the shaft 94. A locking tool 95 on the shaft 94
A spring member 96 made of a compression coil spring interposed between the adapter and the case bottom wall 21 constantly pushes the locking tool 95 upwardly, and the locking tool 95 is moved by the left and right guides 97 and 97 provided on the adapter body side. to guide and prevent rotation. And the intermediate link 73
An engaged portion 98 is cut out on the side edge of the lid 27, and an engaging portion 99 is provided protruding from the rear of the locking member 95 in correspondence with the engaged portion 98. A pressed portion 100 is formed protruding from the front of the locking member 95 in correspondence with the engaging piece 80. However, a portion of the upper end of the pressed portion 100 comes into contact with the wall member 101 on the side of the upper case 20a, so that the upward movement limit of the locking tool 95 is restricted.

In such a case, when the opening/closing lid 27 is opened and the tape drawer members 29 and 30 are in the retracted position,
As shown in FIG.
is pushed upward, and the engaging portion 99 of the locking member 95 engages with the engaged portion 98 of the intermediate link 73,
Since the movement of the intermediate link 73 is locked, the entire tape pull-out mechanism 31 does not operate. Therefore, the operation member 34 cannot be used to pull out the tape. However, when the small tape cartridge 2 is stored in the storage chamber 26 and the opening/closing lid 27 is completely closed, as shown in FIG.
comes into contact with the pressed portion 100 of the locking tool 95 and pushes the entire locking tool 95 downward against the spring member 96. Then, the engaging portion 99 of the locking tool 95 is released downward from the engaged portion 98 of the intermediate link 73, and
This allows the intermediate link 73 to move, ie, the tape pull-out mechanism 31 to operate.

In this way, the operation lock of the tape drawer mechanism 31 is not released unless the opening/closing lid 27 is closed, which means that the front lid 1 of the small tape cartridge 2
This means that the tape can be pulled out only after 6 is opened. In other words, although the small tape cartridge 2 is stored in the storage chamber 26,
If the opening/closing lid 27 is open and you operate the tape drawer, the small tape cartridge 2
Since the front lid 16 is closed, there is a risk that the tape drawer members 29 and 30 may contact and interfere with the front lid 16 and damage the tape 4 and the front lid 16, but this means that such a situation can be prevented. There is.

A gear mechanism is provided in the right lateral space of the adapter body 20 and rotates in conjunction with the movement of the operating member 34 when the tape drawer members 29 and 30 are returned from the drawer position to the retracted position. The mechanism meshes with the drive gear 46 to drive the handle gear 4.
7 to rotate the take-up tape reel 6 in the small tape cartridge in the tape winding direction;
Now transfer the pulled out tape 4 to the take-up tape reel 6.
Although it is designed to be wound up, illustrations and explanations of its specific structure have been omitted.

Although the illustrated example is as described above, the present invention is not limited thereto. For example, in the above embodiment, the opening/closing lid 27 is biased to rotate in the open position by the spring 65, but the spring 65 may be omitted and the opening/closing lid 27 may be opened by hand from the closed state. Further, the front lid 16 of the small tape cartridge 2 may be opened and closed by another means without being linked to the opening/closing lid 27, or the small tape cartridge 2 may be stored with the front lid 16 opened in advance. It may be stored in the chamber 26.

Further, the design of the closing lid locking means of the opening/closing lid 27 can be freely changed; for example, the lid locking device 85 may be freely movable in the front and back direction, or may be mounted so as to be freely rotatable. .

As explained above, according to this invention, when the opening/closing lid 27 is closed on the upper surface of the opening of the storage chamber 26,
The opening/closing lid 27 is automatically locked. Therefore, the opening/closing lid 27 can be closed with a one-touch operation using only one hand without touching the operating knob 84, and since the operating knob 84 only needs to be touched when opening the lid, it is extremely convenient to use, and the opening/closing lid 27 can be closed unexpectedly. It is convenient because it prevents the problem of opening.
