Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is applicable to an electronic camera or the like in which a magnetic disk cartridge (hereinafter referred to as a pack) is inserted.
The present invention relates to a housing-like bucket assembly provided for reliably setting the packs in the recording section, and more specifically relates to a pack ejection structure of the bucket assembly.

(Prior Art) Devices such as electronic cameras that use magnetic disk cartridges (hereinafter referred to as packs) as recording means are provided with a bucket section for setting the packs in the recording section.

This bucket part has an opening at one end into which a pack is inserted, and the other end is rotatably held relative to the recording part by a hinge.
When putting in and taking out a pack, the other end is used as the center of rotation, and by lifting this one end, the pack can be taken in and out easily. This one end is pulled down at the center so that the pack is set in the recording section.

However, in such a device, when one end of the bucket is pulled down, the pack is inserted into the bucket to a predetermined position in order to ensure that the pack is set in the recording section. However, when the pack is to be taken out from the bucket after the recording/playback operation of the pack is completed, it is required that the pack can be easily taken out. It is necessary to forcibly discharge it to

(Object of the Invention) The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a bucket assembly equipped with a discharge mechanism for forcibly discharging packs in response to lifting operation of one end of the bucket. It is something.

(Structure of the Invention) In the bucket bag assembly of the present invention, a locking member locks the discharge lever, which has accumulated spring force by inserting a pack into the bucket bag, and locks the discharge lever in conjunction with the lifting operation only when the bucket bag is pulled up. The device is characterized in that the ejection lever is unlocked by moving the member to the unlocked position, thereby urging the pack toward the pack insertion opening.

That is, the bucket assembly of the present invention has a discharge lever that accumulates spring force when the pack is inserted into the bucket, and uses this spring force to bias the pack toward the pack insertion opening of the bucket, and a discharge lever that is connected to the discharge lever as described above. It is equipped with a locking member that locks at the position where the pack is inserted.When pulling down the bucket to set the pack in the recording section, hold the locking member in the locked position, and when lifting the bucket to insert or remove the pack, lift this member. The locking member is moved from the locking position to the unlocking position using a locking member operating mechanism that moves to release the locking state of the locking member,
This feature is characterized in that the pack is discharged toward the bucket opening using the biasing force of the discharge lever that is released.

(Effects of the Invention) According to the bucket cart assembly of the present invention, the locking member is moved from the locking position to the unlocking position using the locking member operating mechanism that is linked to the lifting operation of the bucket cart, thereby unlocking the discharge lever. That's what I do. Therefore, only when the bucket is lifted to take out the pack, the spring force of the discharge lever can bias the pack in the direction of the pack insertion opening, thereby forcibly ejecting at least a part of the pack to the outside of the bucket. be able to. This allows the operator to easily take out the pack by grasping a portion of the pack discharged to the outside of the bucket.

(Example) Examples of the present invention will be described below with reference to the drawings.

FIG. 1A is a perspective view showing how the pack 3 is inserted with the pack insertion end 2 of the bucket bag 1 lifted.

The bucket 1 has a double structure of a substantially rectangular inner bucket 4 into which the pack 3 is loaded and an outer bucket 5 that covers the outside of the inner bucket 4.

The base 5 is connected to the base 5 by two hinge mechanisms 7 and 8 near the end (hereinafter referred to as the second end) 6 on the opposite side.
0, so that the pack insertion end 2 can be moved up and down. The first end 2 is formed with an opening for inserting the pack, and when the pack 3 is inserted into the inner bucket 4, the pack 3 is inserted into the inner bucket 4 near the first end of the upper wall of the inner bucket 4. A discharge lever 9 that biases one end in two directions;
A lock lever 10 that locks the lock at the position where the spring force is accumulated in the spring 9c by inserting the pack 3.
is formed. Furthermore, this lock lever 10
A slider 11 that engages with the lock lever 10 and a three-dimensional slope cam 12 that engages with the slider 11 serve as a lock release mechanism for releasing the locked state of the ejection lever 9 due to the release mechanism. It is formed in the ivy position. The base 50 is provided with a spindle motor 13 for rotating the pack 3 when the pack 3 is inserted into the bucket 1 and the bucket 1 is pulled down, and a magnetic head 14 for recording and reproducing signals. .

The pack 3 is inserted into the bucket 1, and the bucket 1 is pushed down and rotated to move to the loading position, as shown in FIG. 1B.

FIG. 2 shows an enlarged view of the three-dimensional inclined cam 12 viewed from the direction of arrow C in FIG. 1. As shown in FIG. 2, the cam 12 includes a cam portion 12c having a planar or curved upper slope 12a and a lower slope 12b opposing the upper slope 12a.

Next, the operation of this bucket assembly will be explained. When loading a pack (see Fig. 1A), when the pack 3 is inserted into the inner bucket 4, the protrusion 15 formed on the inner wall of the inner bucket releases the recording/reproducing lock member of the pack while the pack 3 is inserted into the inner bucket 4, and The portion 16 engages with the lid 17 of the pack, and the lid 17 is opened in response to insertion of the pack. As a result, the magnetic disk 3 built into the pack
When the bucket 1 is pushed down with the bucket 1 exposed, the magnetic head 14 can record and reproduce signals on the magnetic disk. If the pack 3 is continued to be inserted, the tip 3a of the pack 3 will push the pin 9a caulked to the lower part of the lever 9. This causes the lever 9 to rotate clockwise (C) when viewed from above the bucket.
direction), and the rotation stops when the pack 3 comes into contact with the wall surface of the second end 6 of the inner bucket.
(See Figure 1B) Also, the pin 9b crimped above the lever 9
The lock lever 10 was prevented from rotating by
When the pin 9b comes off the side end 10a of the lock lever 10 due to the rotation of the lever 9, the pin 9b rotates clockwise (direction D) when viewed from above by the spring 18, and the rotation stops when one end comes into contact with the stopper 19. do. At this time, the pin 9b comes into contact with the tip 10b of the lock lever 10 and moves. lock lever 1
As the lock lever notch 21 rotates, the pin 22 installed on the slider 11 is pressed in the direction of arrow A, and as a result, the slider 11 is activated by the spring force of the spring 20 that urges the slider 11 in the direction of arrow B. It slides in the direction of arrow A against the Here, the spring 18 needs to have a stronger spring force than the spring 20. After the pack is inserted, the outer bucket 5 is pushed down in order to set the pack in the recording section.In conjunction with the movement of the outer bucket 5, the inner bucket 4 also rotates around the hinges 7 and 8 at the first end. 2 is pushed down. This allows the inner bucket 4
The crank pin 23 disposed on the slider 11, which descends integrally with the cam 12, comes into contact with the upper position 12f of the upper slope 12a of the cam 12 and then descends along this slope 12a, so the slider 11 further moves in the direction of arrow A. Moving. When the crank pin 23 reaches the point 12c shown in FIG.
Proceed along 2d. In response to this, slider 11
advances in direction B and stops at the position where the pin 22 abuts the notch 21. At this time, the crank pin 23 stops at a position 12e where it comes into contact with the lower part of the lower slope 12b.

Next, the operation when discharging the pack will be explained. When the outer bucket cart 5 is lifted in order to take out the pack 3 from the bucket cart 1, the first end portion 2 of the inner bucket cart 4 is lifted up with the hinge portion 7 as the center of rotation in conjunction with the lifting operation of the outer bucket cart 5. As a result, the crank pin 23, which is already in contact with the lower slope 12b, rises along the lower slope 12b, and the slider 11 is moved in the direction of arrow B. As a result, the pin 22 resists the spring force of the spring 18. Rotate the lock lever 10 counterclockwise when viewed from above. By further lifting the outer bucket 5, the lock lever 10 rotates in the above-mentioned counterclockwise direction by a predetermined angle or more.
The pin 9b is removed from the pin 0b, and the lever 9 is thereby unlocked. Since the lever 9 has a spring force stored in the spring 9c when the pack is inserted, the lever 9 urges the pack 3 in the direction of the first end 2 at the same time as releasing the lock, and pushes the pack 3 from the opening formed in the first end 2. Expose part of pack 3. This allows the handler to easily take out the pack.

In the above embodiment, a mechanism combining the slider 11 and the three-dimensional slope cam 12 is used as the lock release mechanism, but the lock release mechanism is not necessarily limited to this. It is sufficient that the ejection lever can be unlocked by the locking member.
