When the L-shaped corner portions of a and 41b are reached, the pulling forces of the springs 70 and 80 cause the pins 69 and 79 to move laterally in the L-shaped holes 41a and 41b (Y2, 1 → Y1, in FIG. 1). 2) While sliding on each loader 6
1,71 moves inward. As a result, as shown in FIG. 2, FIG. 3, and FIG. 4, the clampers 65, 75 provided at the other ends of the loaders 61, 71 have lock recesses 7a, which are formed on the lower side of the front end of the data cartridge 5. It comes into contact with the front corner of 7b. Then, the clampers 65 and 75 sandwich the data cartridge 5 from the left and right by the tensile force of the springs 70 and 80, and press the data cartridge 5 against the end portions of the guide rails 10a and 10b. Also, the pins 69 and 79 of the loaders 61 and 71 are attached to the slider 40.
Since the slider 40 is located in the lateral hole portion of the L-shaped holes 41a and 41b, the slider 40 cannot move in the loading / unloading direction (locked state). As a result, the position of the data cartridge 5 is fixed.

The clampers 65, 75 are in contact with the lock recesses 7a, 7b in the state shown in FIGS. 5 and 6. FIG. 5 is an upper sectional view (VV sectional view in FIG. 1), and FIG.
The figure is a side sectional view (VI-VI section). Further, in each drawing, the clamper 65 is shown. The same applies to the clamper 75. As described above, the tension force F0 of the spring 70 acts on the clamper 65. The clamper 65 contacts the front corner of the lock recess 7a and presses the case 6 with force F1 (see FIG. 5). Lateral component F11 of this force F1
Becomes the force for sandwiching the cartridge 5, and the vertical component F12 of the force F1.
Serves as a force for pushing the cartridge 5 forward. Further, as shown in FIG. 6, since the clamper 65 has a truncated cone shape, the force F2 acts diagonally upward on the case 6. Therefore, the upper component F21 of this force F2 becomes a force for pushing the cartridge 5 upward, and the front and rear components F22 of the force F2 become the cartridge 5.
Is the force to push forward. Conventionally, this type of cartridge 5 is fixed by being pressed forward and upward. By making the clamper 65 in the shape of a truncated cone, the force F0 that directly acts on this clamper 65 is
The force acting on the cartridge 5 from the clamper 65 naturally becomes the forward direction (F12, F22) and the upward direction (F21).

When removing the data cartridge 5, the second
When the data cartridge is pulled out in the direction shown by the arrow in the figure, the clampers 65, 75 of the loaders 61, 71 are locked by the lock recesses 7a, 7
Riding on the surface of case 6 from b, loader 61,71 pins on the opposite end
69 and 79 are displaced from the vertical holes of the L-shaped holes 41a and 41b. This unlocks the slider 40 and the springs 58, 59
The pulling force moves the slider 40 toward the insertion port 102 (in the direction of the arrow in FIG. 2), and the data cartridge 5 is taken out accordingly.

In the data cartridge loading mechanism described above, the L-shaped holes 41a and 41b formed in the slider 40, the pins 69 and 79 provided at one end of the loaders 61 and 71, and the springs 70 and 80 (also as a component of cartridge pressing means) The slide means fixing means of the present invention is constituted by (a).

When the position of the data cartridge 5 is fixed as described above, the positional relationship between the data cartridge 5 and the tape drive source 1 is as shown in FIG.

The base member 24 to which the motor 23 is attached is biased by the torsional force of the torsion spring 25 to rotate about the shaft 36. As a result, the roller member 35 provided on the outer circumference of the rotor of the motor 23 is pressed against the drive roller 9 exposed from the opening window of the data cartridge 5 with an appropriate force. In this state, when the motor 23 is energized and the rotor rotates, the rotation is transmitted from the roller member 35 to the drive roller 9. Then, as the drive motor 9 is rotated, the tape 11 in the data cartridge is wound from one reel 12 (or 13) to the other reel 13 (or 12) as in the conventional case, and the tape 11 Becomes a traveling state between the tension rollers 17 and 18. Data is written to and read from the tape 11 in the running state via the head 3.

Since the roller member 35 provided on the outer circumference of the rotor of the motor 23 to be pressed against the drive roller 9 is made of an elastic member such as rubber, the fluctuation of the torque transmitted from the motor 23 side to the drive roller 9 is smaller. Therefore, the running state of the tape 11 becomes more stable.

Further, the drive roller 9 in the data cartridge 5 is driven by a motor.
Since it is directly driven by 23, the number of parts required for the rotation transmission mechanism is extremely small. Furthermore, since the motor 23 is a so-called outer rotor motor,
The height of the tape drive source 1 itself becomes lower, and a tape drive device thinner than the conventional one is realized.

[Effect of device]

As described above, according to the present invention, since the cartridge slidably moved by the slide means is pressed by the cartridge pressing means in the lateral direction of the cartridge, the cartridge is not pressed from below. The cartridge can be loaded at a predetermined recording / reproducing position. Therefore, the device to which the loading device is applied can be made thinner.
