Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a casing provided in an electronic camera or the like in which a magnetic disk cartridge is inserted and the magnetic disk cartridge is securely set in a recording device. The present invention relates to a bucket assembly in the form of a body, and more specifically, to an improvement in the structure of a bucket assembly formed of a double structure of an inner bucket and an outer bucket, both of which are rotatably held relative to a base by a hinge part. It is something.

(Prior art) A magnetic disk cartridge (hereinafter referred to as a pack) used in an electronic camera, etc. is inserted into a housing-like bucket provided in a recording device such as an electronic camera, and then the cartridge is set into the device. Ru.

The recording device has a positioning pin, and the bottom of the pack has a positioning hole.
By rotating (lowering) the pack inserted to the specified position in the bucket in the set direction inside the device, the positioning pin outside the device passes through the through hole drilled in the bottom of the bucket and fits into the positioning hole in the bottom of the pack. This ensures that packs are set correctly.

By the way, the bucket bag is usually held rotatably in the recording device by a hinge near the end (hereinafter referred to as the rear end) opposite to the end for inserting the pack (hereinafter referred to as the front end), and the end for loading the pack, When taking out, the front end is directed diagonally upward.
It is rotated around the hinge attachment part. In such a case, if the distance between the hinge and the positioning pin in the direction of the front and rear ends of the bucket is small, the positioning pin and the positioning hole of the pack cannot be disengaged unless the bucket is opened considerably. Moreover, in order to release the fitting, it is necessary to make the positioning hole a considerably large elongated hole, but it is difficult to use such an elongated hole structure due to the design of the pack.

This problem can be solved by increasing the distance between the hinge and the positioning pin in the direction of the front and rear ends of the bucket, but this increases the size of the bucket itself and cannot be used for products that require compactness.

(Object of the Invention) The present invention was made in view of the above circumstances, and it is an object of the present invention to provide a bucket assembly with a simple structure that facilitates loading and unloading of packs by a slight movement of the bucket. It is.

(Structure of the Invention) The bucket assembly according to the present invention is configured such that, of the inner bucket and the outer bucket that constitute the bucket, the hinge part of the inner bucket can be moved up and down when the outer bucket is rotated, and thereby the pack can be taken out. When lifting the bucket for this purpose, the hinge of the inner bucket lifts up, and even if the lifting angle of the entire bucket (that is, the outer bucket) is reduced, the positioning hole of the pack can be removed from the positioning pin of the device. It is.

That is, the bucket assembly of the present invention has two parts: an inner bucket into which the pack is inserted, and an outer bucket.
It is formed into a heavy structure, and the outer bucket is the first
The inner bucket is rotatably held on the base by a hinge part, and the inner bucket is connected to the outer bucket via a lever that forms the second hinge part, and this lever connects the first shaft and the second shaft. The lever includes a shaft, the first shaft of which is pivotally supported by the outer bucket belt, and the second shaft is pivotally supported by the inner bucket bucket.Furthermore, the lever has an engaging portion ( pin)
is formed, and the base also has an engaging part (cam surface) that engages with the engaging part (pin) of this lever and rotates the lever when the outer bucket is moved upward. This allows the lever to be rotated in such a way that the second shaft can be raised greatly in response to a slight rise in the first shaft, thereby causing the inner bucket to move upwardly when the outer bucket is pivoted upward. It is characterized by a hinge that can be lifted up.

(Effects of the Invention) According to the bucket tote assembly of the present invention, the outer bucket can be connected to the inner bucket at the hinge portion, and the inner bucket can be raised significantly with slight rotation of the outer bucket. .

In other words, when pulling up the outer bucket to point the front end (the end on the pack insertion side) diagonally upward for the purpose of inserting and removing the pack, the rear end of the inner bucket, that is, the opening/closing fulcrum part of the inner bucket was lifted relative to the base. Since the positioning hole of the pack and the positioning pin of the base are set in a shallow state, the inner bucket can be raised and lowered by simply moving the outer bucket up and down a little.
You can freely put in and take out the pack.

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

FIGS. 1 and 2 are perspective views showing a part of a bucket assembly according to an embodiment of the present invention.

This bucket tray assembly has a double structure consisting of an inner bucket tray into which a magnetic disk cartridge (hereinafter referred to as a pack) 1 is inserted, and an outer bucket tray 3 placed so as to cover the outside of the inner bucket tray.

Hinge portions 4 are respectively disposed near the ends (rear ends) on the side opposite to the pack insertion side ends (front ends) of both bucket bags 2 and 3, and at positions facing both ends. When loading and unloading the pack, both bucket bags 2 and 3 are opened and closed using the hinge portion 4 as a fulcrum for opening and closing so that their front ends move up and down.

The hinge portion 4 includes a pair of dogleg-shaped levers 4a and 4b with the convex portion facing upward, and the levers 4a and 4b are bent at the bent portion formed at the end on the outer bucket side. Rivets 4e on 4c and 4d,
It is rotatably attached by 4f. Also, pins 4g to 4 are provided at both ends of the levers 4a and 4b.
The pins 4i and 4j arranged at the end farthest from the front end 5 engage with the engagement grooves 4k and 4l of the inner bucket, and the inner bucket is rotated using this engagement part as a fulcrum. I try to open and close the bucket. On the other hand, pins 4g, 4 arranged at the end near the front end 5
h is arranged so as to come into contact with the edges 7c and 7d of the guide members 7a and 7b fixed to the base 6. Edges 7c and 7d of the guide members 7a and 7b protrude upward and form a smoothly continuous cam surface.

In addition, the outer bucket 3 has fixed hinges 8a and 8b.
(Fig. 2), and is opened and closed around these fixed hinges 8a and 8b.

Further, a spindle 9 and a magnetic head 10 are attached to the base 6, and when the pack 1 is inserted into the inner bucket 2 and set at a predetermined position, signals can be recorded and reproduced on the pack 1.

By the way, as shown in FIG. 3, two positioning pins 9a and 9b are formed on the base 6, and the pack is inserted into the inner bucket 2 (not shown) in the direction of arrow A and set. When this is completed, pack 1 is attached to the positioning pins 9a and 9b.
The positioning holes 10a and 10b of the pack 1 are fitted together to ensure that the pack 1 is set in a predetermined position. Then, when the signal recording and reproduction of the pack is completed and the pack is taken out, the front end 5 is used as the opening/closing fulcrum of the hinge part 4.
Lift it upwards as shown in Figure 4 to eject the pack. However, in such a bucket assembly, the distance between the opening/closing fulcrum 4p and the positioning pin 9b is normally formed to be small due to demands such as downsizing. Therefore, unless the buckets 2 and 3 are opened wide, the positioning pin 9b and the positioning hole 10b will not be disengaged, and the positioning hole 10b will not come off.
This also caused the inconvenience that the hole had to be made quite long.

Therefore, in the bucket tote assembly of the present invention, when the bucket tot is opened, the opening/closing fulcrum part of the inner bucket tot 2 is lifted upward, so that even if the opening of the bucket tot is small, the positioning pin 9b and the positioning hole 10
It is formed so that the fitting of b can be removed. In this embodiment, the structure of the hinge portion 4 allows the opening/closing fulcrum portion of the inner bucket bag 2 to be lifted upward as the outer bucket bag 3 moves upward.
That is, when the outer bucket 3 is opened from the state of the levers 4a and 4b shown in FIG. 5A, the levers 4a and 4b are pulled up in the direction of arrow C as shown in FIG. 5B. Although the distance that the levers 4a, 4b are pulled up is small, when the levers 4a, 4b are pulled up, the pins 4g, 4h implanted at the ends of the levers come into contact with the edges 7c, 7d of the guide members 7a, 7b. The pins 4e, 4 are pulled upward, and the edges 7c, 7d are formed so as to protrude toward the levers 4a, 4b as they move upward.
The lateral distance between f and pins 4g and 4h must be gradually reduced, so that this lever 4
a, 4b are arrows D as pins 4e, 4f rise.
Rotate in the direction. As a result, the pulling distance of the pins 4i and 4j becomes a value that is an expanded value of the pulling distance of the pins 4e and 4f, so that the opening/closing fulcrum of the inner bucket bag 2 can be raised significantly, and the pack 1 can be easily taken in and taken out.

In addition, in the above embodiment, the levers 4a and 4b
Although it is formed in a dogleg shape, the same effect can be obtained by using various other shapes, for example, a substantially straight shape may be used.

Furthermore, the guide members 7a and 7b do not necessarily have to have the shape shown in FIG. It may be of any shape as long as it allows the connection part with the bucket to rotate upward.
