Description

[Detailed Description of the Invention] This invention relates to a tape winder that quickly winds tape on a tape cartridge, and aims to enable the tape cartridge to be easily and stably mounted in a predetermined position.

For example, there is a video tape cartridge as shown in FIGS. 1 and 2 as a tape cartridge that is quickly wound with a tape winder. The front cover 9 is locked with a lock claw 12 to prevent it from opening unexpectedly during normal operation, and a reel brake mechanism 17 is provided to prevent the tape reels 3, 3 from rotating when not in use. Therefore, in order to quickly wind the tape 2 of the tape cartridge with a tape winder, it is necessary to release the lock of the front cover 9 and the lock of the reel brake mechanism 17 before winding the tape quickly. It would be convenient for handling if such an unlocking operation could be performed at the same time as the tape cartridge is installed in the tape winder.

However, when a tape winder is equipped with such a lock release member, strict positioning accuracy of the tape cartridge with respect to the tape winder is required. That is, when the tape reels 3, 3 of the tape cartridge are inserted into or attached to the winding drive shaft and idle shaft of the tape winder, the lock pawl 12 of the front lid 9 of the tape cartridge and the tape reel 3 This is because it is necessary to ensure that each lock release member exactly matches each position of the brake mechanism 17.
However, such a matching state cannot be accurately obtained simply by inserting the tape reels 3, 3 of the tape cartridge into the drive shaft and idle shaft of the tape winder. This is because the tape reels 3, 3 are installed in the main body case 1 so as to be freely movable in the radial direction within a certain range.

Therefore, by separately incorporating a tape cartridge positioning means into the tape winder,
The tape cartridge must be correctly positioned relative to the tape winder.

This invention focuses on this fact and attempts to make it possible to stably, easily, and correctly position and mount a tape cartridge at a predetermined position on a tape winder using a simple positioning means. be.

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 the guide. It is fed out from one reel 3 to the front of the main body case 1 via the members 7, 7, 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 left and right side pieces 9a, 9a pivoted to the main body case 1 so as to be rotatable around left and right support shafts 10, and is always closed by a return spring 11 wound around the support shaft 10 on one side. is activated and locked in the closed position. This locking means includes a lock pawl 12 and a lock release protrusion 13 at one corner of the front inside the main body case 1.
a lock plate 14 having a lock plate 14;
When not in use, the lock pawl 12 and the lock release protrusion 13 protrude outward from each opening in the side wall 1a, and the lock pawl 1
2 engages in the inner recess 16 of one side piece 9a of the front lid 9 to hold the front lid 9 in a closed state. When the video deck is loaded, the lock release protrusion 13 is pushed by the operating member on the deck side, the lock plate 14 is pushed toward the inside of the main body case against the return spring 15, and the lock pawl 12 is released from the front cover 9. It comes off from the recess 16 of the side piece 9a, and the closed lock state is released. Furthermore, 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. In this structure, brake pieces 19, 19 are rotatably supported on support shafts 18, 18 provided upright on the inner bottom surface of the case bottom wall 5, and each brake piece 19, 19, 19 is pressed into a position where it engages with the engaging teeth 21, 21 on the outer periphery of the lower flange of each tape reel 3, 3, and when loaded into the video deck, the brake release pin on the deck side is inserted through the bottom wall 5 of the case. It enters through the operating hole 22 and rotates the brake pieces 19, 19 so that they are disengaged from the engaging teeth 21, 21. These front lid locking means and reel brake mechanism 17 are just examples, and there are several other types of specific structures.

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

At the rear of the mounting surface 25, a front gate-shaped rear wall 28 constituting an outer peripheral wall of 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 biased toward the cartridge rear end surface 1b from the center position of the tape cartridge T in the front-rear direction, there is a gap between the rear end surface 1b and the drive shaft insertion hole. 6
The rear wall 28 and the drive shaft 26
and the idle rotation shaft 27 are dimensioned. In this way, the tape cartridge T can be installed only 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 rear wall 28.

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.

In addition, on the front and right and left sides of the mounting surface 25, a front wall 29 and left and right walls 30, 30, which constitute the outer peripheral walls of the mounting surface 25, are connected to the rear end surface 1b and the left and right end surfaces 1c, 1c of the tape cartridge T. They are erected lower than the rear wall 28 so as to be close to each other and face each other.
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.

In the internal structure of the winder main body 24, a pulley 31 is fixed on the drive shaft 26, and power is transmitted between the pulley 31 and the motor 32 by a belt via an intermediate pulley 33, and a battery 34 is used as the power source for the motor 32.
A motor 32 is housed in an internal space 35 at the rear. An operation panel 36 having a knurled outer periphery is fixed on the idle shaft 27, and a part of the circumference of the operation panel 36 faces the outside through a recessed part 37 formed in the front surface of the winder main body 24. There is.

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 in the front-rear direction on the left and right walls 30, 30 on the mounting surface 25, there is a presser lever 42 having a head 41 for pressing the left and right ends of the upper surface of the tape cartridge T. It is pivotably mounted around a shaft 43 so as to be able to switch between the outwardly tilted position of 30 and 30, and is biased by a spring 44 so as to always be in the 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 outer circumferential wall portions 29, 3.
Since it is formed higher than 0.30, the rear wall 28
If the tape cartridge T is lowered in a horizontal position by aligning the front surface of the front cover 9 of the tape cartridge T with the front surface of the tape cartridge T, the tape cartridge T will be properly placed on the mounting surface 25 with the front and rear positional displacement controlled. be done. In this mounted state, the drive shaft 26 and the idle shaft 27 fit into the reels 3, 3 on the drive shaft insertion holes 6, 6 of the tape cartridge T, and the brake release member 40 operates to release the brake of the tape cartridge T. Hole 22
to remove 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 protrusion 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 state is achieved, the operation panel 36 is rotated to wind the tape 2 around the reel 3 on the free rotating shaft 27 to eliminate slack in the tape and bring it into a tensioned state. After that, when the motor 32 is driven, the intermediate pulley 3
3 and belt transmission, the drive shaft 26 rotates, and the tape 2 is quickly wound onto the reel 3 on the drive shaft 26.

After fast winding is completed, the presser levers 42 are again tilted outward to the left and right, and then the tape cartridge T is taken out upward.

In addition, as shown in FIG. 6, the operation panel 36 and the free rotating shaft 2
If one or more intermediate gears 47 are interposed between the tape 2 and the
It is possible to eliminate slack.

In addition, in order to facilitate the removal of the tape cartridge T, a presser lever 42 is provided as shown in FIG.
A push-up portion 45 is provided at the lower end, and when the presser lever 42 is tilted, the push-up portion 45 projects upward from the notch 46 of the placement surface 25, and the tape cartridge T is pushed upward from the placement surface 25. Just do it.

If a part of the circumference of the operation panel 36 is exposed outward from the main body case 24 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 tape winding state can be seen through the transparent window 1d on the top surface of the tape cartridge T. This becomes even more convenient in cases where it cannot be visually recognized.

If a part of the circumference of the operation panel 36 faces outside the winder main body 24 and rotates with the free rotating shaft 27 during fast tape winding, the operation panel 36 may be touched by the user's hands, which is considered dangerous, as shown in FIG. Both 36 and 47 are connected between the operation panel 36 and the gear 47 on the free rotating shaft 27.
A contact/separation gear 48 is installed that can move toward and away from the
During early winding, the approaching/separating gear 48 may be moved away from the operating panel 36 and the gear 47 by external operation of the main body case 24 to prevent the operating panel 36 from rotating.

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.

The entire details of the illustrated embodiment are as described above.
The present invention can of course be applied to various tape cartridges other than video tape cartridges. Also, instead of making the rear wall 28 higher, the front wall 29 is made higher than other surrounding wall parts, and the front surface of the tape cartridge T, etc. is mounted on the mounting surface 25 using the front wall 29 as a guide. You may also do so.

As explained above, in the tape winder of this invention, the surrounding wall consisting of the front and rear walls 28, 29 and the left and right walls 30, 30 is erected on the outer periphery of the mounting surface 25 on which the tape cartridge T is mounted. These surrounding walls surround the tape cartridge T on the mounting surface 25 at its front, rear, left and right ends in close proximity to and opposite to each other. Therefore, the tape cartridge T can be stably wound without horizontally moving or wobbling on the mounting surface 25, and can be quickly wound in a well-positioned state with correct positioning. In particular, since one of the front and rear walls 28 and 29 of the surrounding wall is made higher than the other three surrounding walls, the tape cartridge T can be easily installed from above between the surrounding walls surrounding it on all four sides. It's possible and easy to use.
