Description

[Detailed Description of the Invention] This invention relates to a tape winder that quickly winds the tape in a tape cartridge, and is characterized in that it is equipped with a means for preventing uneven winding of the tape.

In the tape cartridge shown in FIGS. 1 and 2, it is desirable that the tape 2 is wound in tension between the left and right tape guide members 7, 7 on the front surface of the main body case 1. The tape is loose on the front of the case. Such tape slack is mainly caused by rattling of the tape reels 3, 3 in the tape cartridge. Generally, a reel brake mechanism 17 is provided to prevent the rotation of each tape reel 3, 3 when not in use, but even when the brake is applied, there is room for each tape reel 3, 3 to rotate slightly due to play of the brake. These are also causes of tape slack.

If such tape slack occurs, when winding the tape with a tape winder, the tape 2
cannot be wound on the reel 3 in an orderly manner, resulting in irregular winding.

This invention focuses on this fact and eliminates slack in the tape in the tape cartridge to keep it in a tensioned state before fast winding.

The details will be explained below based on the drawings.

Figures 1 and 2 show an example of a standard video tape cartridge to which the tape winder of the present invention is applied, with tape reels 3, 3 on which tape 2 is wound on the left and right sides of the main body case 1 of this cartridge. It is rotatably mounted so as to be positioned above each drive shaft insertion hole 6 transparently provided in the case bottom wall 5, and tape guide members 7, 7 are arranged on the front left and right sides of the main case 1, and the tape 2 is attached to these. Guide members 7, 7
It is fed out from one reel 3 to the front of the case via the holder and wound onto the other reel 3.

A front cover 9 that covers and protects the outside of the tape 2 is attached to the front of the main body case 1 so as to be openable and closable. The front lid 9 has its left and right pieces 9a, 9a pivoted to the main body case 1 so as to be rotatable around the left and right support shafts 10, and is always supported by the force of a return spring 11 wound around the support shaft 10 on one side. It is biased closed and locked in this closed state. . This locking means includes a lock plate 14 having a lock pawl 12 and a lock release protrusion 13 at one front corner of the main body case 1, and a return spring that always presses the plate 14 toward the main case side wall 1a. 15, and when not in use, the lock pawl 12 and the lock release protrusion 13 protrude outward from each opening of the side wall 1a,
The lock claw 12 is located in the inner recess 1 of the one side piece 9a of the front cover 9.
6 to hold the front lid 9 in a closed state. When the tape cartridge is loaded into the video deck, the lock release protrusion 13 is pushed by the operating member on the deck side, the lock plate 14 is pushed inward against the return spring 15, and the lock claw 12 is pushed into the front cover 9. It comes off from the recess 16 of the one side piece 9a, and the closed lock state is released. Further, a reel brake mechanism 17 is provided at the rear central portion of the main body case 1 to prevent rotation of each tape reel 3 when not in use. This means that the brake pieces 19, 19 are attached to the support shafts 18, 18, which are installed upright on the inner bottom surface of the case bottom wall 5.
The spring members 20, 2 are pivotably supported around the spring members 20, 2.
0, each brake piece 19, 19 is connected to the engaging teeth 21, 21 on the outer periphery of the lower flange of each tape reel 3, 3.
When the video deck is loaded into the video deck, the brake release pin on the deck side enters through the operation hole 22 provided through the bottom wall 5 of the case, and the brake pieces 19, 19 are pushed into the engagement teeth 21, 21. It is designed to be rotated so that it comes off. These front lid locking means and reel brake mechanism 17 are just examples, and there are several other concrete structures.

3 to 5 illustrate the tape winder of the present invention, in which a mounting surface 25 for horizontally receiving and supporting the tape cartridge T is formed on the upper surface of the winder main body 24. This mounting surface 2
Two engagement shafts 26 and 27 are provided on the left and right sides of the tape cartridge T to engage the reels 3 and 3 on the drive shaft insertion holes 6 and 6 of the tape cartridge T. One of them 26 is a drive shaft, and the remaining 27 are idle shafts.

A rear wall 28 constituting an outer circumferential wall behind the mounting surface 25 is provided higher than the top surface height of the tape cartridge T. That is, since the center of the drive shaft insertion hole 6 of the tape cartridge T is offset from the center position of the tape cartridge T in the front-rear direction toward the rear end surface 1b of the cartridge,
The rear wall 28, the drive shaft 26 and the idle shaft 2 are arranged so as to match the distance between the rear end surface 1b and the drive shaft insertion hole 6.
The distance between 7 and 7 is set as the dimension. With this,
The tape cartridge T can only be installed in a posture in which the front lid 9 of the tape cartridge T in the closed state abuts against the rear wall 28 and faces the front cover 9 .

On the mounting surface 25 at the lower part of the rear wall 28, there is a space S sufficient for opening the front lid 9 when the tape cartridge T is mounted on the mounting surface 25.

Further, on the front and left and right sides of the mounting surface 25, there is a front wall 29 and left and right walls 3 that constitute the outer circumferential walls of the mounting surface 25.
0 and 30 are erected lower than the rear wall 28.
The distance between the front and rear walls 29 and 28 is approximately the same as the entire length of the tape cartridge T in the front and rear direction, and the left and right walls 3
The distance between 0 and 30 is approximately the same dimension as the entire length of the tape cartridge T in the left and right direction.

Inside the winder body 24, the drive shaft 2
A pulley 31 is fixed on the top of the pulley 31, and the pulley 31 and the motor 32 are transmitted by a belt through an intermediate pulley 33. A battery 34, which is the power source of the motor 32, and the motor 32 are stored in an internal space 35 at the rear. has been done. A rotary operation panel 36 having a knurling on the outer periphery is fixed on the free rotating shaft 27, and a part of the circumference of the rotary operation panel 36 is exposed to the outside through a recessed part 37 formed on the front surface of the winder main body 24. It's coming.

On the mounting surface 25, a front lid opening member 38 and a front lid lock release member 39 are erected on the rear right side, and a brake release member 40 is erected on the front central portion. Further, at approximately the center of the left and right walls 30, 30 in the front-rear direction, a presser lever 42 having a head 41 that presses the left and right ends of the upper surface of the tape cartridge T is installed in an upright position and on the outside of the left and right walls 30, 30. Axis 4 allows switching between tilting and tilting positions.
3, and is biased by a spring 44 so as to be always in an upright position.

Next, we will explain how to install the tape cartridge T and how to quickly wind it.The left and right presser levers 4
2 and 42 to the left and right outwards, and the tape cartridge T is placed on the placement surface 25 from above. At this time, the rear wall 28 is connected to the other peripheral wall portions 29, 30, 3.
0, so if the front surface of the front cover 9 of the tape cartridge T is aligned with the rear wall 28 and the tape cartridge T is lowered in a horizontal position, the tape cartridge T will move forward and backward. The positional shift is controlled and placed correctly on the placing surface 25. In this mounted state, the drive shaft 26 and the idle shaft 27
is engaged with the reels 3, 3 on the drive shaft insertion holes 6, 6 of the tape cartridge T, and the brake release member 4
0 enters the brake release operation hole 22 of the tape cartridge T and removes the brake pieces 19, 19 from the engagement teeth 21, 21 of the tape reels 3, 3. Further, the front lid lock release member 39 presses the lock release projection 13 of the tape cartridge T to release the closed lock state of the front lid 9, and the front lid opening member 38 pushes the front lid 9 up a little to open it.

Next, the presser levers 42, 42 are raised to press the left and right ends of the upper surface of the tape cartridge T.

After this mounting condition is established, the rotary operation panel 36 is rotated to wind the tape 2 onto the tape reel 3 on the free rotating shaft 27 to eliminate tape slack. After that, when the motor 32 is driven, the intermediate pulley 33
and the drive shaft 26 rotates via belt transmission,
The tape 2 is rapidly wound onto a tape reel 3 on a drive shaft 26. After fast winding, the presser lever 42,
42 is tilted outward to the left and right, and then the tape cartridge T is taken out upward.

In addition, as shown in FIG.
7, it is possible to eliminate slack in the tape 2 with a slight rotational operation force.

In order to facilitate the removal of the tape cartridge T, a raised part 45 is provided at the lower end of the presser lever 42 as shown in FIG. Section 46
It will be more convenient if the tape cartridge T is projected upward from the mounting surface 25.

The rotary operation panel 36 has a part of its circumference attached to the main body case 2.
If the rotating state of the tape 2 is projected outward from the tape 4 so that the rotating state can be seen, the fast-winding state of the tape 2 can always be visually recognized. In particular, in a configuration in which a lid (not shown) is attached to the mounting surface 25 to cover the upper part of the tape cartridge T, the lid is opaque and the state of tape winding cannot be visually recognized through the transparent window 1d on the top surface of the tape cartridge T. This becomes even more convenient in such cases.

If a part of the circumference of the rotary operation panel 36 faces outside the main body case 24 and rotates with the free rotating shaft 27 during fast tape winding, the rotary operation panel 36 may be touched by hands, which is considered dangerous. As shown, between the rotary operation panel 36 and the gear 47 on the idling shaft 27, there is a
A contact/separate gear 48 that can move toward and away from the tape 6 and 47 is installed, and the contact/separate gear 4
8 to the rotary operation panel 36 by external operation of the main body case 24.
The rotary operation panel 36 may be prevented from rotating by moving it away from the gear 47.

The present invention can also be applied to various tape cartridges other than video tape cartridges. In addition, the rotary operation panel 3
6 may be made to face the outside from one side of the left and right sides of the winder main body 24. Furthermore, it goes without saying that the tape 2 may be wound quickly on both the take-up reel and the feed reel in the tape cartridge T.

As explained above, in the tape winder of this invention, the engagement shaft 26, preferably the free rotation shaft 27, can be rotated by the rotary operation panel 36, so when the tape cartridge T is wound quickly, the tape winder can be rotated. Even if there is slack in the shaft 2, use the rotary operation panel 36 to remove the shaft 2 together with the engagement shaft 27 before starting early winding.
By rotating the tape reel 3 on the tape 7, the tape 2 can be brought into tension, which is advantageous in preventing step winding due to tape slack.
