I do. To this end, the end portion of the leader tape has a tongue piece provided with a keyhole-shaped connection hole. On the upper and lower edges of the tape of the tongue piece, a locking piece for positioning and holding the tongue piece when not in use is formed, and a slit-like engagement groove is formed in the center of the tape surface near these locking pieces. It is formed. A stopper claw is provided inside the loading opening of the case main body, and the stopper claw is engaged with the engaging groove, thereby defining a tape winding limit.

[Problems to be solved by the invention]
In many cases, the leader tape is formed of a plastic sheet slightly thicker than the magnetic tape, and has a sheet strength enough to withstand the insertion / removal operation by the catcher of the tape drive. However, if the tape cartridge is used for a long period of time or if the cumulative number of times the tape cartridge is used exceeds a certain number, the engagement groove, the hook and the like may be damaged. Especially when rewinding the tape, the tape wound at a high speed is caught by the stopper claw and stops suddenly, so a large impact force acts on the groove end of the engaging groove, and a crack is continuously generated at the groove end or it is caught The pieces may be damaged.
[0004]
SUMMARY OF THE INVENTION It is an object of the present invention to reduce the impact acting on the leader tape by a buffer between the time when the leader tape is rewound and the time when the engagement groove is caught by the stopper pawl and the stopper groove stops, so that the engagement groove and the hook are prevented. It is an object of the present invention to provide a tape cartridge which can prevent a large impact force from acting on a stopper or the like, prevent the tape end portion structure from being damaged, and can therefore be used without trouble even during long-term use.

Fixed to.
[0011]
Operation and Effect of the Invention
In the present invention, the stopper claw 24 can be held at the steady standby position by the buffer 32, and the impact of the leader tape 4 colliding with the stopper claw 24 is moderately absorbed by the elastic deformation of the buffer 32. Further, it is possible to prevent the engagement groove 18 provided in the tape end portion 20 from colliding with the stopper claw 24 and suddenly stopping. Therefore, it is possible to prevent a large stress due to the collision from acting on the engaging groove 18 and the engaging piece 17 and to prevent the tape end structure from being damaged. That is, a tape cartridge that can be used without any problem even during long-term use is obtained.
[0012]
According to the tape cartridge in which the buffer 32 is formed integrally with the case main body 1, a buffer function can be added without increasing the number of components, and the manufacturing cost of the tape cartridge can be reduced accordingly.
[0013]
A buffer 32 made of an elastic material is disposed between the receiving seat 36 of the case main body 1 and the stopper claw 24, and the impact of the collision when the leader tape 4 collides with the stopper claw 24 is reduced by the elasticity of the buffer 32. According to the tape cartridge configured to be relaxed and absorbed by the deformation action, the elastic deformation stress of the buffer 32 and its change characteristics can be variously set by changing the material, shape, structure, and the like of the elastic material. Therefore, the buffering characteristics of the buffer 32 are more suitable.
[0014]
According to the cushioning member 32 formed of a leaf spring-like elastic material as an independent component, the collision impact acting on the stopper claw 24 can be buffered and absorbed by simply adding a spring component having a simple structure, and the buffering force can be optimized. Thus, the leader tape 4 can be reliably prevented from being damaged. The reliability in long-term use is improved accordingly.
[0015]
When the cushioning member 32 is formed of a compression coil spring, similarly to the cushioning member 32 formed of a leaf spring-like elastic material, the collision impact acting on the stopper claw 24 can be accurately determined only by adding a spring component having a simple structure. Thus, the leader tape 4 can be reliably prevented from being damaged. There is an advantage that the change characteristic of the deformation stress when the buffer body 32 is elastically deformed can be set accurately, and the occupied space is small.
[0016]
When the buffer 32 is formed of a rubber elastic material, the rate of increase of the deformation stress when the buffer 32 is elastically deformed is reduced as compared with the case where the buffer 32 is formed of an elastic body such as a leaf spring or a coil spring. Since the leader tape 4 can be set to a large value, the leader tape 4 moves in the tape pull-in direction in response to a collision impact, and the movement stroke until the leader tape 4 stops can be reduced. That is, it is possible to effectively absorb and absorb the impact while reliably avoiding an excessive impact force acting on the engagement groove 18 and the engaging piece 17.
[0017]
According to the tape cartridge, at least the hook portion 27 of the stopper claw 24 is formed of a rubber elastic material, so that the impact when the engaging groove 18 collides with the hook portion 27 can be buffered by the elastic deformation action of the hook portion 27. For example, a buffer function can be added without increasing the number of parts. In addition, since the hook portion 27 itself against which the engaging groove 18 collides is elastically deformed to absorb and absorb the collision shock, it is possible to eliminate a large collision stress from acting on the groove end of the engaging groove 18 and to effectively absorb the shock. It works. Further, there is an advantage that the variation in the position of the tape end portion 20 when not in use is small as compared with the case where the entire stopper claw 24 moves by the amount of deformation of the buffer 32 to reduce the impact.
[0018]
The stopper claw 24 is formed of a rubber elastic material including the hook portion 27 and is fixed to the outer groove wall 23b of the stopper guide groove 23, so that the collision impact when the leader tape 4 collides with the stopper claw 24 is reduced. According to the tape cartridge which absorbs and absorbs the elastic deformation of the tape cartridge, the structure of the stopper claw 24 is simplified as compared with the case where the entire stopper claw 24 is formed of a rubber elastic material, and the manufacturing cost of the tape cartridge is reduced accordingly. Can be Further, similarly to the stopper claw 24 described in the preceding paragraph, which is formed of a rubber elastic material, the hook portion 27 itself against which the engaging groove 18 collides is elastically deformed to absorb and absorb the collision impact. There is also an advantage that the application of a large collision stress can be eliminated, and the variation in the position of the tape end portion 20 when not in use is reduced.

Reference numeral 30 denotes a catch groove formed between the hook 27 and the arm 26.
[0026]
When the magnetic tape 3 and the leader tape 4 are wound around the reel 2 at a high speed, the leader tape 4 is caught by the stopper claws 24 and suddenly stops, or the hanging piece 17 collides with the groove end of the guide groove 23. In order to avoid this, the stopper claw 24 fitted in the mounting portion 28 is received by the buffer 32.

To cushion the impact. That is, the stopper claw 24 that has received the leader tape 4 is displaced from the standby position in FIG. 1 to the buffer position in FIG. 5 almost simultaneously with receiving an impact. The shock of the tape 4 is absorbed and absorbed. Therefore, a large impact force is prevented from acting on the leader tape 4, and a crack is prevented from being generated at the groove end of the engaging groove 18.
