Abstract

PURPOSE:To eject forcibly a pack in response to the lifting of one end of the bucket by using a spring force of an elastic member only in lifting up the bucket to energize the pack in a pack loading opening direction. CONSTITUTION:In lifting up an outer bucket 5 to eject the pack 3 from a bucket 1, an inner bucket 4 lifts up the 1st end 2 around a hinge 7 in interlocking with the lifting of the outer bucket 5. Since a crank pin 23 which is in contact with a lower slope 12b already rises along the lower slope 12b, a slider 11 is moved toward the arrow B and a pin 22 rotates counterclockwise a lock lever 10 against the spring force of a spring 18. In lifting up further the outer bucket 5, the lock lever 10 is rotated counterclockwise by a prescribed angle or over, the locking of a lever 9 is released because a pin 9b is unlocked from the tip 10b of the lock lever 10 and a part of the pack 3 is exposed from the opening provided to the 1st end 2.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a housing provided in an electronic camera, etc., into which a magnetic disk cartridge (hereinafter referred to as a back) is inserted, and the back is securely set in a recording section. The present invention relates to a body-shaped bucket assembly, and specifically relates to a back discharge structure of the bucket assembly.

(Prior Art) A device such as an electronic camera that uses a magnetic disk cartridge (hereinafter referred to as a pack) as a recording means is provided with a bucket section for setting the bag in a recording section.

This bucket section has an opening at one end into which a bag is inserted, and the other end is rotatably held relative to the recording section by a hinge.

When putting in and taking out the bag, the other end is used as the center of rotation, and by lifting this one end, the bag can be taken in and out easily, and when recording and playing back, the other end can be rotated. This one end is pulled down at the center so that the pack is set in the recording section.

By the way, in such a device, when one end of the bucket is pulled down, the pack is inserted to a predetermined position inside the bucket in order to ensure that the pack is set in the recording section. However, when taking out the pack from the bucket after the recording/playback operation of the pack is completed, it is required that the pack 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 circumstances, and it is an object of the present invention to provide a bucket assembly equipped with a discharging mechanism for forcing a pack out in response to lifting operation of one end of the bucket. This is the purpose.

(Structure of the Invention) The bucket assembly of the present invention locks the spring force by the accumulated elastic members ξ and n-tuck members when the pack is inserted into the bucket, and is linked to this pulling operation only when pulling up the bucket. The present invention is characterized in that the locking member is moved to the unlocking position to unlock the elastic member, thereby urging the pack toward the pack insertion opening.

That is, the bucket assembly of the present invention includes an elastic member that accumulates spring force when a 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 resilient member that is attached to the pack. It is equipped with a locking member that locks in the inserted position, and when pulling down the bucket to set the pack in the recording section, the locking state is maintained by the locking member, and when lifting the bucket to take out and insert the pack, this locking state is maintained. The locking member is moved from the locking position to the unlocking position using the locking member operation mechanism that is linked to the operation, thereby releasing the locked state by the locking member, and thereby ejecting the pack toward the bucket opening using the released biasing force of the elastic member. It is characterized by the fact that it is made to do so.

(Effect of the invention): According to the bucket...11-assembly of the invention, the locking member is moved from the locking position to the unlocking position by using the interlocking locking member operating mechanism. ?
Move it T' to unlock the elastic member. Therefore, only when the bucket i~ is lifted in order to take out the pack, the spring force of the elastic member can bias the pack towards the pack insertion opening. External t:
Can be forcibly ejected. This allows the handler to easily take out the pack by grasping a portion of the pack that has been taken out of the bucket.

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

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

It consists of a double structure of a roughly rectangular inner bucket 4 and an outer bucket 5 that covers the outside of this inner bucket 4, and both buckets 4 and 5 are packed. The shaft is rotatably pivoted with respect to the base 50 by two hinges 17.8 near the end (hereinafter referred to as the second end) 6 opposite to the insertion end (hereinafter referred to as the first end) 2. supported,
This allows the bag insertion end 2 to be moved up and down. An opening for inserting the pack is formed in the first end 2, and a first earth wall of the inner bucket 4 is formed.
Near the end, when the pack 3 is inserted into the inner bucket 4, there is one lever that urges the pack 3 toward the first pant part 2, and the lever 9 is moved to a position where spring force is accumulated by inserting the pack 3. A lock lever 10 is formed to lock at. As a lock release mechanism for releasing the locked state of the lever 9 by the 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 are installed on the outer surface and the inner surface of the upper wall of the inner bucket, respectively. It is formed along the outer surface of the bucket side wall. Note that when the pack 3 is inserted into the bucket 1 and the bucket 1 is pulled down on the base 50,
A spindle morph 13 for rotating the back 3 and a magnetic head 14 for recording and reproducing signals are provided.

FIG. 2 is an enlarged view of the three-dimensional slope cam 12 viewed from the direction of arrow C in FIG. 1. According to FIG. A cam portion 12C having a lower slope 12bS facing the slope 12a is provided.

Next, the operation of this bucket assembly will be explained. When loading a bag, 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/reproduction locking member of the pack while the pack 3 is inserted into the inner bucket 4, and the claw part 16 locks the lid part 17 of the bag. This lid portion 17 is opened in response to the insertion operation of the pack. This exposes the magnetic disk built into the bag, and bucket 1
When the pack 3 is pulled down (signals can be recorded and reproduced on the magnetic disk using the 4-way head 14), insert the pack 3 and continue to press C. 9a.This causes the lever 9 to rotate clockwise when viewed from above the bucket.
The rotation of the bag 3 stops when it comes into contact with the wall surface of the second end 6 of the inner bucket. Further, when the lock lever 10, which has been prevented from rotating by the pin 9b caulked above the lever 9, is removed from the side end 10a of the lock lever 10 due to the rotation of the lever 9, the spring 18 prevents the lock lever 10 from rotating from above the bucket. It rotates clockwise when viewed, and the rotation stops when one end comes into contact with the stopper 19. At this time, the pin 90 comes into contact with the tip 10b of the lock lever 10 and moves. As the lock lever 10 rotates, the lock lever notch 21 presses the pin 22 implanted on the slider 11 in the direction of the arrow, and the slider 11 is activated by the spring 20 that urges the slider 11 in the direction of the arrow B. slide in the direction of the arrow against the spring force of. Here, spring 18 is spring 2
It is necessary to make the spring force stronger than 0. After the bag is inserted, the outer bucket 5 is pressed down to set the pack in the recording section.
In conjunction with this movement, the first end portion 2 of the inner bucket 4 is also pulled down with the hinge portions 7 and 8 as rotation centers. As a result, the crank pin 23 disposed on the slider 11, which descends integrally with the inner bucket 4, comes into contact with the upper part @ 12f of the upper slope 12a of the cam 12, and then descends along this slope +28, so that the slider 11 moves further in the direction of the arrow.

When the crank pin 23 reaches a point 12C shown in FIG. 3, it moves along the surface 12d due to the urging force of the spring 20. Correspondingly, the slider 11 advances in the direction B and stops at a position where the pin 22 abuts the notch 21. At this time, the crank pin 23 is placed at a position 12e in contact with the lower part of the lower slope 12b.
Stop at.

Next, the operation of opening the bag when discharging it will be explained. When the outer bucket 5 is lifted in order to take out the bag 3 from the bucket 1, the first end 2 of the inner bucket 4 is lifted around the hinge part 7 as the center of rotation in conjunction with the lifting operation of the outer bucket 5. As a result, the crank pin 23, which is already in contact with the lower slope 12b, rises along the lower slope 12b, so the slider 11 is moved in the direction of arrow B, and as a result, the pin 22 resists the spring force of the spring 18. and rotate the lock lever 10 counterclockwise when viewed from above. By roughly lifting the outer bucket 5, the lock lever 10 is rotated counterclockwise by a predetermined angle or more, and the pin 9b is disengaged from the tip 10b of the lock lever 10, thereby unlocking the lever 9. Since the lever 9 has accumulated spring force when the bag is inserted, it urges the bag 3 in the direction of the first end 2 at the same time as the lock is released, and pushes the bag 3 through the opening formed in the first pant part 2. expose a part. This allows the handler to easily take out the pack.

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