Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention comprises a reel stopper member for stopping the rotation of a tape reel when not in use and a tape slack preventing member for preventing the tape from slackening to the front surface of the case. The tape cartridge is characterized by the releasing means for both the reel stopper member and the tape slack preventing member.

[Conventional technology]

FIG. 5 illustrates a conventional tape cartridge (for example, Japanese Utility Model Laid-Open No. 58-87184). There, reels 3 and 3 around which the tape 2 is wound are rotatably incorporated inside the main body case 1 composed of the upper and lower cases 1a and 1b, and a tape loading pocket 4 is provided on the front surface of the main body case 1.
.4, and the tape guide members 5 and 5 are arranged on the left and right of the pockets 4 and 4.
The tape 2 is led out from one reel 3 to the front of the pocket 4 via the reel and wound on the other reel 3.

The reel 3 has a lower flange 6 protruding from a claw 7 and is provided with a reel stopper member 10 that abuts and engages with the claw 7 to prevent the reel 3 from rotating when not in use and release the engagement when in use. It is supposed to do.

However, although the reel 3 is prevented from rotating by the reel stopper member 10 when not in use, the reel 3
The tape 2 is easily loosened on the front surface of the case due to rattling or the like. This slackening of the tape may lead to defective loading of the tape 2.

Therefore, a tension member 9 for applying a tension to the tape 2 is provided on the way of the tape running path between the one tape guide member 5 and the reel 3 to prevent the tape from slackening.

However, if the tension member 9 is pressed against the tape 2 even when the tape is running during use, the load during running the tape increases and the tape 2 is damaged, so use it to eliminate this. At times, the tension member 9 is released from the contact with the tape 2.

[Problems to be solved by the invention]

However, in the above-mentioned conventional example, since the reel stopper member 10 and the tape tension member 9 have to be separately released at the time of use, these release operating members must be individually incorporated in the deck side, and the number of release operating members is reduced. In addition, it is necessary to form an operation port for releasing each of the members 9 and 10 on the main body case side of the tape cartridge, so that the case strength tends to be reduced. There was a flaw.

In view of such a fact, an object of the present invention is to devise a releasing means for both the reel stopper member and the tape slack preventing member so that both releasing operations can be performed simultaneously by one releasing operation member. .

[Means for solving problems]

In order to achieve the above object, in the present invention, as shown in FIG. 1, a reel stopper member 10 for preventing reel rotation is attached to the reel 3 in a main body case 1 in which a reel 3 around which a tape 2 is wound is rotatably incorporated. The tape slack prevention member 11 is mounted movably between a lock position where it is abuttingly engaged and a lock release position where it is disengaged from the reel 3.
It is assumed that the tape cartridge is movably mounted between a position where the tape is pressed against and a position where the tape is released from the tape 2.

In addition, a releasing means 12 is provided for interlocking the releasing operation of the reel stopper member 10 to the unlocked position and the releasing operation of the tape slack preventing member 11 to the pressing release position. As a specific example of the releasing means 12, for example, as shown in FIGS. 1 and 2, a movement for moving the reel stopper member 10 to the unlocked position by utilizing the movement of the tape slack prevention member 11 to the pressed release position. A transmission mechanism is provided between both members 11 and 10. Alternatively, as shown in FIG. 4, the reel stopper member 10 and the tape slack preventing member 11 are integrally structured so that both members 10 and 11 can be released simultaneously by moving them in a fixed direction.

[Action]

Then, when the tape slack prevention member 11 is not used, the tape slack prevention member 11 is pressed against and abutted against the tape 2 so that the tape slack is prevented. When the tape is used, the tape slack prevention member 11 is released from abutment with the tape 2. This will reduce the driving load. Also, the tape slack prevention member 1
The reel stopper member 10 is linked to the reel 3 in association with the release of the reel 1.
Will be disengaged.

〔The invention's effect〕

According to the present invention as described above, when the tape is not used, the tape slack preventing member 11 is pressed against the tape 2 to prevent the slack from coming out, so that the tape loading failure can be eliminated. Tape slack prevention member 11 when used
Since the tape 2 can be separated from the tape 2, the tape 2 can be stably run without receiving a running load, and the tape is not damaged. Moreover, since the reel stopper member 10 is disengaged from the reel 3 in association with the releasing operation of the tape slack prevention member 11, one of them can be shared and used as the releasing operation member on the deck side.
The structure on the deck side can be simplified accordingly. Further, on the side of the main body case 1, it suffices to provide one opening for releasing both members 10 and 11, which is advantageous in assuring the case strength.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

Since the overall structure of the tape cartridge is almost the same as the conventional one described above, only the differences from the conventional tape slack preventing member and reel stopper member will be described.

1 to 3 show an embodiment of the present invention,
On the way of the tape running path between the reel 3 in the main body case 1 and the tape guide member 5 located in front of it,
The tape slack prevention member 11 is incorporated together with the reel stopper member 10. The tape slack preventing member 11 is composed of a tape pressing pin 13a made of a stainless steel rod or the like, and a swing arm 13b having the pin 13a standing on the upper surface of the tip. The swing arm 13b has a bearing portion 14 at its base end, and the bearing portion 14 is rotatably inserted through an arm support shaft 17 projecting from a position near the side wall 16 of the bottom wall 15 of the case. It is supported on the inner bottom wall 15 of the case so as to be swingable right and left around the shaft 17 by a predetermined angle. That is, as shown in FIG. 1, the tape slack preventing member 11 is at a position where the tape pressing pin 13a is pressed against the tape 2 and when the tape pressing pin 13a is completely released from the tape 2 as shown in FIG. It is swingable around the arm support shaft 17 over the position. The position is regulated by bringing the swinging arm 13b into contact with the ribs 18 that are disposed on the left and right sides of the arm support shaft 17 on the inner bottom wall 15 of the case so as to face each other and the regulation surface 19 of the front side wall 16a. . The tape slack prevention member 11 is constantly urged in one direction by the torsion coil spring 20 on the arm support shaft 17 so that the tape pressing pin 13a is pressed against the tape 2.

A flexible and freely deformable tape-pressing piece 22 made of a polyester sheet or the like is mounted on the side surface of a rib 21 which is continuously formed rearward from the tape guide member 5 of the main body case 1. The tape-pressing piece 22 and the tape Sag prevention member 1
By sandwiching the tape 2 with the tape pressing pin 13a of No. 1, the tape 2 is prevented from loosening toward the front of the case.

The reel stopper member 10 is arranged on the inner bottom wall 15 of the case between the lower flange 6 of the reel 3 and the base end of the swing arm 13b. The reel stopper member 10 has a bearing portion 23, and the bearing portion 23 is provided on the inner bottom wall 15 of the case so as to stand upright behind the arm spindle 17 and a stopper support shaft 24.
A lock that is rotatably inserted into and supported by the claw 25 and that is integrally formed at the front end of the bearing 23 as shown in FIG. 1 engages between claws 7 of the lower flange 6 of the reel 3. It is swingable around the stopper support shaft 24 between the position and the unlocked position shown in FIG. The reel stopper member 10 is constantly urged to swing toward the locked position by a torsion coil spring 27 fitted on a spring receiving shaft 26 provided upright from the inner bottom wall 15 of the case in the vicinity thereof. The spring 2
The arm portion 27a at one end of 7 is engaged with the spring receiving portion 28 on the reel stopper member 10, and the arm portion 27b at the other end is engaged with the rear side wall 16 of the body case 1, respectively.

The unlocking operation of the reel stopper member 10 and the pressing release operation of the tape slack prevention member 11 are both members 10.1.
The release means 12 provided between the two is operated by one release operation member 29 on the deck side.

Regarding the releasing means 12, as a releasing mechanism of the tape slack prevention member 11, a releasing piece 30 is integrally formed on one side rearward of the bearing portion 14 at the base end of the swing arm 13b, and the releasing piece 30 is attached to the front and rear portions of the side wall 16. The operation port 31 formed in the notch between the side walls 16a and 16b faces the outside of the case. On the other hand, it is assumed that the reel stopper member 10 swings in the unlocking direction in response to the swinging movement of the swinging arm 13b in the unlocking direction of the reel stopper member 10. Specifically, a pin-shaped stopper releasing member 32 is erected on the upper surface of the base end of the swing arm 13b rearward of the bearing portion 14, and the rear end portion 3 formed rearward of the bearing portion 23 of the reel stopper member 10 is provided.
3 is brought into contact with the side of the stopper releasing member 32 in the swinging direction.

At this time, when the tape cartridge is loaded into the deck, the release operation member 29 on the deck side comes into contact with the release piece 30 of the tape slack prevention member 11 and moves to the rear of the case as shown in FIG. When the release piece 30 is pushed into the operation port 31, the tape slack prevention member 11 swings around the arm support shaft 17 to the pressure release position, and the tape pressing pin 13
a will be completely separated from the tape 2. At the same time, the reel stopper member 10 receives the pushing force of the stopper releasing member 32 at its rear end portion 33 and swings around the stopper support shaft 24 to the lock releasing position, and its claw 25 is reeled.
It will be separated from the claw 7 of the lower flange 6. The released state of the tape slack prevention member 11 and the reel stopper member 10 is maintained by the release operation member 29 continuously pressing the release piece 30 of the swing arm 13b.

When the tape cartridge is taken out from the deck, the release operation member 29 releases the pressure of the release piece 30, and the tape slack prevention member 11 returns to the position where the tape 2 is pressed and abutted by the force of the spring 20, and the tape 2 is taped. It is sandwiched between the holding piece 22 to prevent the loosening. At the same time, the reel stopper member 10 is returned to the locked position by the force of the spring 27 to prevent the reel 3 from rotating.

[Another embodiment]

FIG. 4 shows another embodiment of the present invention, which is intended for a reel 3 in which the winding direction of the tape 2 is different from the reel 3 of the above-mentioned embodiment, and the tape pressing pin 13a and the swing arm are provided. Tape loosening prevention member 11 including 13b
And the reel stopper member 10 are integrated.
The rotating body 34 in which the tape slack prevention member 11 and the reel stopper member 10 are integrally formed is formed by integrally forming the swing arm 13b, the reel stopper member 10, and the release arm 36 radially from the central bearing portion 35. The bearing portion 35 is rotatably inserted through a support shaft 37 provided upright on the bottom wall 15 of the case, and the tape pressing pin 13a is attached to the tape 2
The hook 25 of the reel stopper member 10 is engaged with the hook 7 of the lower flange 6 of the reel 3, and the release arm 36 is formed as a straight cutout from the front end of the case inner bottom wall 15 to the rear. It is arranged on the inner bottom wall 15 of the case so as to face the operation port 38. Further, the spring 39 mounted on the support shaft 37 maintains the contact state of the tape slack prevention member 11 with the tape 2 and the claw engagement state of the reel stopper member 10 with the reel 3 so that the rotating body 34 can be maintained. Is urged to rotate until a part of the contact part comes into contact with the rotation restricting protrusion 40. Then, when the release operation member 29 on the deck side is inserted into the operation port 38 and the release arm 36 is pushed, the rotating body 34 rotates against the spring 39 and the tape slack preventing member 11 is completely removed from the tape 2. The reel stopper member 10 is detached from the reel 3 at the same time when the reel stopper member 10 is released.

In each of the above-described embodiments, the tape slack preventing member 11 is brought into contact with one side of the tape 2 and the tape pressing piece 22 is brought into contact with the other side of the tape 2 to prevent the tape 2 from coming loose. However, the present invention is not limited to this, for example, the tape pressing piece 22 may be omitted and the tape slack prevention member 1
The present invention can be similarly applied to the case where the tape 2 is prevented from being loosened by applying a tension to the tape 2 by the pressing contact action of only 1.
