[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view showing a cartridge magnetic tape drive device of the embodiment and a cartridge mounted in the cartridge magnetic tape drive device. Since the structure of the cartridge 1 is the same as that of FIG. 9, its explanation is omitted.

In the cartridge magnetic tape drive, 11 is a case formed in a box shape, and the cartridge 1 is inserted into the front surface 11a exposed on the operation panel of the case 11 in the longitudinal direction indicated by the arrow B with the end face 1b as the head. An opening 11b is formed, and a door 12 is attached to the insertion opening 11b, the upper side of which is pivotally supported by the upper edge of the insertion opening and opens into the case 11. Also,
A cartridge ejection key 13 is provided on the front surface 11a of the case 11.

FIG. 1 is a perspective view when the case 11 is removed.
The figure is a plan view and FIG. 4 is a side view. A sliding plate for guiding the cartridge 1 inserted on the upper surface of the plate-shaped frame 14 that contacts the lower side of the insertion port 11b of the front surface 11a of the case 11.
15a and 15b are attached, and a container mechanism 16 as a cartridge carrying mechanism having a U-shaped cross section in the extension direction of the sliding plates 15a and 15b is movably mounted in the moving direction of the cartridge 1. The bottom plate 16 of this container mechanism 16
A guide bearing that engages with a guide rod 17 provided in a rectangular window 14a formed in the frame 14 is attached to the lower surface of a, and the container mechanism 16 moves along the guide rod 17.

On the lower surface of the lower plate 16a of the container mechanism 16, a latch 18a is provided with a shaft 18b.
Is pivoted at. At one end 18c of the latch plate 18a, there is formed a concave portion to be engaged with the engaging portion 14b formed on the upper surface of the frame, and the other end 18d of the latch plate 18a is bent upward to form the end surface 1b of the cartridge 1. Contact plate 16b with which
Located outside. The spring 18e is attached to the other end 18d.
Is attached, and the latch plate 18a is biased counterclockwise about the shaft 18b. A part of the other end 18d is bent into the container mechanism 16. Therefore, the front end of the cartridge 1 inserted from the insertion port 11b is the container mechanism 16
When the end face 1b is inserted between the lower plate 16a and the upper plate 16c and the end face 1b contacts the contact plate 16b, the other end 18d of the latch plate 18a is pushed by the end face 1b. As a result, the latch plate 18a rotates clockwise, and the one end 18c is released from the locking portion 14b. Therefore, this container mechanism 16 becomes movable. Then,
The latch plate 18a, the shaft 18b, and the spring 18e constitute a latch mechanism 18.

A micro switch 19 is provided near the rectangular window 14a on the lower surface of the frame 14 to detect that the container mechanism 16 has started moving by contacting a bearing mounted on the lower surface of the lower plate 16a. .

Further, a spring plate 20 that curves upward is attached to the lower plate 16a of the container mechanism 16.

A long hole 16d is formed in one end of an upper plate 16c of the container mechanism 16, and one end of an operating arm 16e is connected to this long hole 16d. The operation arm 16e is rotatably supported by a shaft 14c fixed to the frame 14 via a plate (not shown), and the other end of the operation arm 16e is formed on a side surface of a rack plate 21 as an operation restraining mechanism. It is locked in the locking groove 21a. Therefore, when the rack plate 21 moves toward the insertion port 11b, the operation arm 16e rotates clockwise around the shaft 14c, and the container mechanism 16 moves toward the specified position in the inner part of the case 11. Conversely, when the rack plate 21 moves in the direction away from the insertion port 11b, the container mechanism 16 moves in the insertion port 11b direction.

On the upper surface of the frame 14, a cartridge insertion completion detector 22 that detects that the cartridge 1 held by the container mechanism 16 has reached a specified position, and that the container mechanism 16 that holds the cartridge 1 has reached a specified position. A container position detector 23 for detecting is provided, and this cartridge insertion completion detector 22 or container position detector 23 is provided.

A pair of stoppers 24a, 24b are provided to prevent the cartridge 1 from moving beyond the specified position.

Further, an L-shaped protrusion 16f protruding outward is formed at the boundary between the lower plate 16a of the container mechanism 16 and the contact plate 16b. The protrusion 16f engages with the notch 10a formed in the end surface 1b of the cartridge 1 only when the cartridge 1 is properly inserted into the front and back. However, if it is not properly inserted, the protrusion 16f contacts the part of the end face 1b where the notch 10a is not formed, and therefore the end face 1b of the cartridge 1 does not move further in the contact plate 16b direction. It does not contact the other end 18d of 18a. Therefore, since the latch mechanism 18 is not unlatched, the container mechanism 16 does not start moving toward the specified position. That is, the protrusion 16f has a function of preventing the cartridge 1 from being inserted in the wrong direction.

Further, the frame 14 is provided with a window 14d having a shape shown in the drawing, and a movable plate 27 having a head vertical moving mechanism 26a for vertically moving the magnetic head 25 by a magnetic head 25 and a motor 26 is provided in the window 14d. It is arranged. This movable plate 27 is a window
It is possible to move in a direction perpendicular to the moving direction of the cartridge 1 by a guide rod 17a provided in 14d. This movable plate 27 is a shaft
The lower end of an operating arm 28 having a U-shaped cross section is pivotally supported via 28a, and the other end of the operating arm 28 is pivotally supported by the frame 14 via a shaft 28b. A protrusion 2 that engages with a guide hole 21b formed in the rack plate 21 is provided on the upper end of the operating arm 28.
8c is formed.

On the lower surface of the frame 14, a capstan motor 29 having a capstan roller 29a attached to its tip and extending upward through the window 14d is rotatably supported by a shaft 29b. The shaft 28a at the lower end of the operating arm 28 is pivotally supported on the upper surface of the capstan motor 29.

FIG. 5 is a diagram showing the operation of the operation arm 28. In the drawing, the U-shaped operation arm 28 is shown as a flat plate. When the rack plate 21 moves toward the insertion port 11b, the projection 28c of the operation arm 28 is guided by the guide hole 21b and moves toward the capstan roller 29a, and the operation arm 28 moves along the shaft 28b.
Rotate clockwise around the center of the
Along the direction toward the cartridge 1. Further, since the capstan motor 29 rotates clockwise about the shaft 29b, the capstan roller 29a also moves toward the cartridge 1.

An access door opening mechanism 30 is attached to the frame 14. This access door opening mechanism 30 is a frame
A guide hole 21 that is axially supported by 14 and has an upper end formed on a rack plate 21.
A shaft 30a penetrating upward through c, an operating arm 30b attached to the shaft 30a, and a release lever 30c of the access door 9.
A protrusion 30d attached to the upper surface of the operation arm 30b and engaging with another guide hole 21d formed in the rack plate 21, and a curved portion formed at the end of the rack plate 21 formed at the tip of the operation arm 30a. It is composed of a sliding shaft 30e that slides along 21e. Further, a guide plate 30 for guiding the opened access door 9 of the cartridge 1 to the side is provided on the upper surface of the frame 14.
f Installed.

When the rack plate 21 moves toward the insertion port 11b, the shaft 3
The protrusion 30d slightly rotates clockwise around 0a, and the curved portion 21e of the rack plate 21 comes into contact with the sliding shaft 30e. Further, when the rack plate 21 is moved toward the insertion port 11b, the sliding shaft 30e slides on the curved portion 21e. That is, the shaft 30a rotates clockwise, the opening lever 30c rotates clockwise,
The opposite end 9a of the access door 9 of the cartridge 1, which is moving in the case 11 toward the specified position, is pressed down, and the access door 9
To release. The access door 9 moves laterally along the guide plate 30f as the cartridge 1 moves in the specified position.

As shown in FIG. 4, one end of an operating arm 31 for opening and closing the door 12 is pivotally supported on the side surface of the frame 14 via a mounting member 31a. The door 12 is attached to the other end of the operating arm 31.
Locking part 3 for locking the lever rod 12a mounted inside
1b is installed. The lower side of the operating arm 31 is in contact with a sliding shaft 21g pivotally supported on the lower portion of a support plate 21f attached to the side surface of the rack plate 21.

Also, a spring (not shown) is attached to the door 12,
Normally, the door 12 is closed by the biasing force of this spring.

Then, when the rack plate 21 starts to move toward the insertion port 11b, as shown in FIG. 8, the operation arm 31 rotates clockwise, the locking portion 31b at the tip moves upward, and the door 31b moves upward. The lever bar 12a of 12 is rotated upward. Then, the insertion port 11b
The door 12 is opened inward. Further, when the rack plate 21 is moved in the direction of the insertion port 11b, the contact position of the sliding shaft 21g moves to the distal end portion of the operation arm 31, so that the operation arm 31 rotates counterclockwise and the locking portion. 31b moves down and door 12
Closes again. That is, the door 12 is opened only when the rack plate 21 is located at the middle position of the moving range.

A rack plate moving motor 33 is fixed to the upper surface of the frame 14, and a worm gear 33a is attached to the rotation shaft of the rack moving motor 33, and the rotation direction is perpendicular to the gear 33b locked to the foam gear 33a. Is converted to. Gear 33b
Is transmitted to the final gear 33e via the gears 33c and 33d. This gear 33e is a guide hole 21h formed in the rack plate 21.
It engages with a linear gear engraved on one side.

Therefore, when the rack moving motor 33 is rotated, the rack plate 21 moves in the insertion port 11b direction or the specified position direction.

Further, projections 21i and 21j are attached to the lower surface of the rack plate 21, while a discharge completion detector 34 is attached to the frame 14 via a support member. This discharge completion detector 34
The relative positions of the projections 21i and 21j are such that the ejection completion detector 34 is activated by the projections 21j when the rack plate 21 is positioned most in the insertion port 11b direction, that is, when the mounting of the cartridge 1 is completed. Further, when the rack plate 21 is located closest to the specified position, that is, when the cartridge 1 is completely ejected, the ejection completion detector 34 is activated by the protrusion 21i.

Next, the operation of the cartridge magnetic tape drive device having such a configuration will be described.

First, when the cartridge 1 is not inserted, it is in the state shown in FIGS. 1, 3, and 4, and the rack plate 21 is located at the end of the case 11 at the specified position side.
Therefore, the container mechanism 16 is in a state of being latched by the latching portion 18 of the frame 14 by the latch mechanism 18, and the magnetic head 25 and the capstan roller 29a are retracted.

When the cartridge 1 is inserted into the insertion port 11b with the end face 1b at the head as shown in FIG.
The door 12 is pushed inward at b. Further, when the cartridge 1 is inserted, the end surface 1b of the cartridge 1 enters between the upper plate 16c and the lower plate 16a of the container mechanism 16, and when further pushed in, the end surface 1b of the cartridge abuts the abutting plate 16b. Then, the tip 18d of the latch mechanism 18 is moved in the insertion direction, and the latched state of the latch mechanism 18 is released.
Further, when the cartridge 1 is pushed in, the unlatched container mechanism 16 starts moving in the insertion direction (direction of the specified position). Then, the micro switch 19 operates, the rack plate moving motor 33 is activated, and the rack plate 21 starts moving toward the insertion port 11b.

When the rack plate 21 starts moving, the container mechanism 16 holding the cartridge 1 automatically moves along the guide rod 17 toward the specified position. Therefore, the operator has only to release the hand from the cartridge 1. Further, when the rack plate 21 starts to move and the rear end surface 1c of the cartridge 1 is drawn into the case 11, the curved portion 21e of the rack plate 21 contacts the sliding shaft 30e of the access door opening mechanism 30. Then, the opening lever 30c starts rotating clockwise to open the access door 9,
As shown in FIG. 6, the access door 9 is guided toward the guide plate 30f.

Then, when the cartridge 1 reaches the specified position with the access door 9 opened, the projection 28c of the operation arm 28 locked in the guide hole 21b is forcibly moved toward the cartridge 1, so that the magnetic head 25 And the capstan roller 29a starts moving toward the cartridge 1.

When the rack plate 21 moves most toward the insertion port 11b, the protrusion 2
At 1j, the discharge completion detector 34 operates and the rack plate moving motor 33 stops. When the cartridge 1 is located at the specified position, the magnetic head 25 contacts the magnetic tape 3 and the capstan roller 29a is pressed against the capstan 3, as shown in FIGS. 6 and 7. Also, the insertion port 11b
The door 12 is closed by a spring. Therefore, it becomes possible to write / read data to / from the magnetic tape 3 of the cartridge 1.

After writing and reading data, this cartridge 1
To eject the cartridge, press the cartridge ejection key 13. Then, the rack plate moving motor 33 starts to rotate in the reverse direction, and
21 starts moving from the position in the insertion port 11b direction in FIGS. 6 and 7 toward the specified position. When the rack plate 21 starts moving, the operating arm 28 first rotates, and the magnetic head 25 and the capstan roller 29a retract. Next, the access door opening mechanism 30 starts to operate, and the opening lever 30c rotates counterclockwise. Further, the operation arm 31 attached to the side surface of the frame 21 rotates to open the door 12. Then, the rack plate 21 further moves toward the specified position, the end surface 1c of the cartridge 1 is exposed from the insertion port 11b, and the rack plate 2
When the discharge completion detector 34 provided between the frame 1 and the frame 14 operates, the rack plate moving motor 33 stops. Then, the operator pulls out the cartridge 1 from the insertion port 11b.
Then, the door 12 is closed by a spring. Further, in this state, as shown in FIG. 3, the container mechanism 16 is latched by the latch mechanism 18 to the locking portion 14b of the frame 14.

With such a cartridge magnetic tape drive,
When the cartridge 1 is inserted until it abuts on the contact plate 16b of the container mechanism 16, the cartridge 1 automatically moves to the case 11
It is installed (autoloading) at the specified position in the back. Therefore, the operability can be significantly improved as compared with the conventional magnetic tape drive device.

When the cartridge ejection key 13 on the front surface 11a of the case 11 is operated by a key, the door of the insertion port 11b of the case 11 is automatically opened, and the cartridge 1 mounted at the specified position in the case 11 is inserted and opened. A part including the end face 1c is automatically discharged to the mouth 11b. Therefore, the operator can
The cartridge 1 discharged to b may be pulled out. That is, even when the cartridge 1 is taken out, only one key operation is required. Therefore, the operability can be further improved.

Further, by using the latch mechanism 18 and the micro switch 19 as the cartridge insertion detector, the rack plate movement motor 33 is activated only when the cartridge 1 is correctly inserted to the contact plate 16b position of the container mechanism 16. Therefore, the container mechanism 16 starts to move in a state where the cartridge 1 is not correctly inserted into the container mechanism 16, and the opening lever 30c, the magnetic head 25, and the capstan roller 29a do not contact the correct position on the side surface 1a of the cartridge 1. It can prevent a situation from occurring.

In addition, the end face of the cartridge 1 is provided on one side of the container mechanism 16.
Since the protrusion 16f that engages with the notch 10a of 1b is formed, the latch mechanism 18 is not unlatched when the cartridge 1 is inserted in the wrong direction. Therefore, the container mechanism 16 does not start moving while the cartridge 1 is inserted in the wrong direction. Therefore, the safety and reliability of the device can be further improved.

Furthermore, since the container mechanism 16 is provided with the spring plate 20, the vertical position of the cartridge 1 is fixed, and the fluctuation error of the width direction position of the magnetic head 25 with respect to the magnetic tape 3 is suppressed.

Further, by providing the container position detector 23 and the cartridge insertion completion detector 22 independently, it is assumed that the container mechanism 16 has moved and reached the specified position even if the cartridge 1 is not inserted by mistake. Also, since only the container position detector 23 operates and the cartridge insertion completion detector 22 does not operate, the rack plate moving motor 33 stops. Therefore, it is possible to prevent the constituent members from being damaged.

[Effects of the Invention] As described above, according to the cartridge magnetic tape driving device of the present invention, when the cartridge is inserted into the insertion opening in the longitudinal direction, the cartridge is automatically pulled in to the specified position inside the case (auto load). Dig) function is added. Therefore, the operability can be significantly improved.

Further, since various confirmation means and mechanisms are provided, the cartridge can be surely automatically attached and the reliability of the operation can be improved.

Further, since the function of automatically ejecting the cartridge is added by one cartridge ejection command input represented by a key operation, the operability can be further improved.

Further, since the access door of the cartridge is opened in the case, the shape of the insertion port of the cartridge can be maintained while maintaining a shape close to the cross section in the direction orthogonal to the longitudinal direction (longitudinal direction) of the cartridge. The cartridge can be automatically mounted in the longitudinal direction (autoloading), and the area at the time of opening is small, so that foreign matter is less likely to enter the case. In addition, the access door opening mechanism does not need to be exposed on the front surface of the panel before inserting the cartridge, which improves the operability.
