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 stores a small tape cartridge by inserting it from above into a storage chamber provided in the adapter body, which has substantially the same external shape as a large tape cartridge, and then inserts the tape from the small tape cartridge into the adapter body. It is designed to be loaded into a magnetic recording device after being pulled out to the front side.

Therefore, in order to smoothly pull out the tape from the small tape cartridge, the small tape cartridge must be stored in the storage chamber in a normal state without wobbling. However, in order to facilitate insertion and removal, the small tape cartridge is stored in the storage chamber with some margin in the front, rear, left, right, and top and bottom directions. For this reason, the tape pull-out operation is performed with the small tape cartridge particularly vertically displaced or not completely stored in the storage chamber, which may lead to a tape pull-out failure.

Therefore, the present invention pivots an opening/closing lid that closes the top of the opening of the storage chamber to the adapter body, and if the small tape cartridge is not stored in the storage chamber and the opening/closing lid is closed, the opening/closing lid can be used to hold the small tape cartridge normally. The tape can be pulled out only when it is in the stored state, thereby making the tape pulling operation more appropriate and preventing the tape from being damaged.

In addition, among video adapters, the small tape cartridge is stored in the storage chamber with its front cover closed, and the front cover of the small tape cartridge is opened in conjunction with the closing operation of the opening/closing cover. This has been proposed by the applicant, but in this case, if the tape drawer is operated with the opening/closing cover open, the front cover on the small tape cartridge side is closed, so the tape drawer member contacts and interferes with the front cover. , damage the front lid and tape. The specific example of the present invention is designed to solve such problems at the same time.

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.

When closed, the leaf springs 67, 67 elastically press and support the upper 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. The opening/closing lid 27 is provided with 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.
When the front lid 16 is kicked upward against the spring member 19 at a, and the opening angle of about 45° is exceeded, the front lid 16 automatically assumes an open position by the spring member 19, and when the opening/closing lid 27 is closed, the front lid 16 is lifted upward against the spring member 19. The claw 70a serves as a support and absorbs the external force applied by a finger or the like to the front lid 16, and the front lid 16
maintain the 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 comes into contact with the front lid 16 as shown in FIG. 9 and presses the front lid 16 downward. 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 feeding 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 do this, in FIGS. 3 and 4, a pin 74 is set up on the intermediate link 73 of the link mechanism 32 for moving the left tape pull-out member 29, and the base end of the lock arm 75 is attached to the inner surface of the upper case 20a of the adapter body 20. The lock arm 75 is rotatably supported, and the distal forked portions of the lock arm 75 are connected to the pin 74, and a lock piece 76 is connected 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 76 is locked as shown in FIG.
However, 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. 4, and the small tape car Semicircular recess 7 formed on the outer surface of the rear wall 77 of the tray 2
A locking piece 76 is engaged with the small tape cartridge 9 to fix 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 on the upper surface of the upper case 20a. A plate-shaped lid lock 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 of the adapter body 20, and is integrally connected to the knob 84 within the adapter body 20 and is movable horizontally in the left and right directions. A tool 85 is attached.

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 provided on the left and right front ends of the lid locking device 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.

Further, a locking portion 91 is protruded from the lower surface of the lid locking device 85, and a stopper 92 is provided on the lock arm 75 to come into contact with the locking portion 91.

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 locking tool 85 is urged to move rightward as shown in FIG. From this state, the small tape cartridge 2 is stored in the storage chamber 26, and the opening/closing lid 27 is pushed against the spring 65 into the storage chamber 26.
When it is completely closed to the top of the opening of 6, the opening/closing lid 2
7, the inclined surface 81 of each pressing engagement piece 80 comes into contact with the inclined surface 90 of the lid locking tool 85, and the lid locking tool 85 itself resists the spring member 88 to release the lock on the left side. When the lid locking tool 85 is pushed to the right position and the pressing engagement piece 80 goes over each of the engaging pieces 89 of the lid locking tool 85 and goes around to the lower side, the lid locking tool 85 automatically returns to the right side by the spring member 88. The engaging surface 82 of each pressing engaging piece 80 engages with the lower surface of each engaging piece 89 in a manner that prevents it from coming off, thereby locking the opening/closing lid 27 in the closed position. 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 7
5 rotates and the stopper 92 provided on it
As shown in FIG. 3, 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, after the tape drawer operation, the operation knob 84
The opening/closing lid 27 cannot be opened. Therefore, after the tape drawer operation, the opening/closing lid 27 is opened by mistake, and the front lid 16 is closed in conjunction with this, and the front lid 1 is closed.
6, 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, 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, the locking member 95 may be abuttingly engaged with another portion of the tape pull-out mechanism 31 instead of the intermediate link 73. This tape drawing mechanism 31 may also include a gear mechanism or a belt winding mechanism in part.
Further, the operating member 34 may be of a linear sliding type or a rotary dial type. Furthermore, in the illustrated example, the pressing engagement piece 80 of the opening/closing lid 27 is also used to lock the opening/closing lid 27; Needless to say, it is also possible to provide only one.

Further, in the illustrated example, the front lid 16 of the small tape cartridge 2 opens in conjunction with the closing operation of the opening/closing lid 27, and the front lid 16 remains closed while the opening/closing lid 27 is open. Therefore, when it is said that the small tape cartridge 2 is stored in the storage chamber 26 but the opening/closing lid 27 is open, that is, the front lid 16 of the small tape cartridge 2 in the storage chamber is still open. If it is determined that the opening operation has not been performed, the tape drawer operation cannot be performed, so the tape drawer members 29 and 30 are pulled forward and come into contact with and interfere with the front cover 16, causing the tape 4 and the front cover 16 to
It is designed to not cause any damage to the body. However, the present invention is not limited to opening the front lid 16 of the small tape cartridge 2 in conjunction with the closing operation of the opening/closing lid 27. The small tape cartridge 2 may be stored in the storage chamber 26 with the front lid 16 open in advance, or the small tape cartridge 2 may be stored in the storage chamber 26 with the front lid 16 open.
After storing the small tape cartridge 2 in 6,
The front cover 16 may be opened by another means.

As explained above, according to this invention, even if the small tape cartridge 2 is stored in the storage chamber 26, the tape 4 cannot be pulled out from the small tape cartridge 2 as long as the opening/closing lid 27 is open. A tape pull-out mechanism 31 that moves the tape pull-out members 29 and 30 that are waiting at retracted positions on the left and right front sides of the storage chamber 26 is locked. Only after the opening/closing lid 27 is closed, the operation lock of the tape drawing mechanism 31 is released and the tape 4 can be drawn out from the small tape cartridge 2. Therefore, the tape drawer operation is performed with the small tape cartridge 2 properly stored and set in the storage chamber 26 using the opening/closing lid 27.
This has the advantage that the tape drawing operation from the small tape cartridge 2 can be carried out reliably.
