[Patent Document 2]
Japanese Patent Laid-Open No. 2001-101675
In such a disk device provided in such a camera, a configuration in which the disk cartridge is inserted / removed through an elongated insertion opening opened in the housing is usually used in order to minimize exposure inside the main body when the disk cartridge is inserted / removed. It is often adopted. Moreover, the door which opens and closes this is provided in an insertion port.
[0006]
As shown in FIG. 8, such a door 52 is attached to the housing 54 via a hinge mechanism h, and is urged to a closed position where the insertion port is closed by a torsion coil spring (not shown). When the disk cartridge is inserted, the disk cartridge is tilted into the housing 54 as indicated by an arrow, and the disk cartridge can be inserted from the insertion port.
[0007]
[Problems to be solved by the invention]
However, in the above conventional example, the outer surface 52a of the door 52 is smooth, and when the water droplet a adheres at the closed position that closes the insertion slot and tilts as it is, the disk inside the housing 54 is shown in FIG. The water droplet a falls to the cartridge loading section. The loading unit is provided with an optical pickup, a semiconductor laser, a circuit board, and the like, and there is a possibility that the water droplets a may cause a failure thereof.
[0008]
The present invention has been made in view of the above-described problems, and an object of the present invention is to prevent water droplets from falling onto the loading portion of the disk cartridge even when the door is tilted with water droplets attached to the outer surface of the door. It is an object of the present invention to provide a disk device and a camera having the same.
[0009]
[Means for Solving the Problems]
In solving the above problems, in the disk device of the present invention, water droplets attached from the outside are opened on the outer surface of the door that opens and closes the insertion port formed in the housing in which the loading portion is disposed. It is characterized in that a water drop fall prevention means is provided for preventing it from falling into the loading part at the position.
[0010]
The water drop fall prevention means is formed in the direction of drop of the water drop when the door is tilted, and has a function of preventing the drop of the water drop. As a result, it is possible to prevent water droplets from entering the loading section and to inhibit the cause of the failure.
[0011]
In the disc device according to the present invention, the water drop fall prevention means is a step portion extending in the longitudinal direction of the door.
[0012]
The door is pushed by the end of the disc cartridge and begins to tilt. At this time, even if water droplets adhere to the outer surface of the door, the water droplets are blocked by the stepped portion, and the water droplets are prevented from falling. Is done. As a result, it is possible to prevent the cause of failure due to the ingress of water droplets.
[0013]
The stepped portion may be provided as a convex portion protruding in the thickness direction of the door, or may be provided as a concave portion recessed in the thickness direction of the door.
[0014]
In the case where the stepped portion is a convex portion that protrudes in the thickness direction of the door, it can be easily retrofitted to the door and is easy to implement. However, when it is provided so as to hit the edge of the insertion opening of the housing, it is necessary to craft a work for receiving such a convex portion (for example, providing a recess in the insertion opening edge). In addition, it is necessary to set the protruding height so that the end of the disk cartridge does not get caught by the protruding portion and is prevented from being inserted.
[0015]
In the case where the step portion is a concave portion that is depressed in the thickness direction of the door, water droplets are blocked by the side wall portion of the recess of the concave portion. In this case, it can be realized with a simple structure without requiring any work in the vicinity of the insertion opening of the housing. Further, in the case of the concave portion, compared with the convex portion, the end of the disc cartridge is less likely to be caught, so that the disc cartridge can be inserted smoothly.
[0016]
Further, the concave portion can also function as an insertion guide for smooth insertion of the disc cartridge if the shape thereof is adapted to the shape of the end portion of the disc cartridge.
[0017]
In the disk device of the present invention, the concave portion is provided with a rib that partitions the central portion of the door. With this rib, the central portion and the others can be divided within the recess, and a large amount of water droplets can be prevented. Thereby, it is possible to reliably protect optical parts such as a pickup that is most sensitive to water droplets and electronic components from the water droplets in the loading unit.
[0018]
Further, the disk device of the present invention is characterized in that the water drop fall prevention means is made of a water absorbing material extending in the longitudinal direction of the door.
[0019]
When the door is tilted, even if water droplets adhere to the outer surface of the door, the water absorbing material absorbs the water droplets, and the water droplets are prevented from falling. As a result, it is possible to prevent the cause of failure due to the ingress of water droplets.
[0020]
Examples of the water absorbing material include a nonwoven fabric and a paper material. The water absorbing material may be attached to the outer surface of the door, or the outer surface of the door may be made of a material having water absorption. If the water-absorbing material is attached, the initial water-absorbing function can be easily restored by replacing the water-absorbing material when large droplets are attached, such as when a disk device is used in rainy weather. Further, in the case of pasting, retrofitting is easy and no other work is required.
[0021]
Further, in the present invention, the water drop dropping prevention means is characterized in that a water absorbing material is laid on the bottom surface of a recess that extends in the longitudinal direction of the door and is recessed in the thickness direction of the door. .
[0022]
According to this configuration, the presence of the recess can prevent water droplets from sliding onto the outer surface of the door at once and falling into the loading portion, and the water absorbing material can absorb water while the drop of the water droplet is blocked by the recess. be able to. The water absorbing material extends in a direction substantially orthogonal to the direction toward the loading portion in the tilted state of the door, and on the loading portion side in the tilted state of the door of the damming portion of the recess. It is effective if provided. In this case, water droplets overflowing from the recesses can be absorbed by the water absorbing material. As described above, the synergistic action of the recess and the water absorbing material can surely prevent the water droplet from falling.
[0023]
The camera of the present invention is characterized by including the disk device described above. That is, in the camera of the present invention, the imaged data can be recorded on a disk-shaped recording medium in a disk cartridge loaded in the loading unit of the disk device.
[0024]
The disk device has a relationship that constitutes a camera as a built-in device. Cameras are often used outdoors, and water droplets tend to accumulate on the outer surface of the door when used in rainy weather or due to changes in temperature and humidity associated with movement from the outside to the room. Is strong.
[0025]
In the present invention, the disk cartridge is not limited to a structure in which one disk-shaped recording medium (optical disk, magneto-optical disk, magnetic disk) is rotatably accommodated in a space formed in a flat cartridge. In addition, one having a structure (so-called portable hard disk) in which one or a plurality of magnetic disks and a magnetic head for reading and writing with respect to the magnetic disk are accommodated in the casing is also included.

[0036]
(Door structure)
FIG. 5 shows the inner surface side of the right side housing 4b (the side facing the loading portion 24). On the rear surface of the edge of the U-shaped notch 10b constituting the half of the insertion port 10 is larger than the size of the insertion port 10 via a hinge mechanism including a shaft member 26, a torsion coil spring 25, and the like. A rectangular door 12 is attached.
[0037]
The shaft member 26 extends along the longitudinal direction of the door 12 and penetrates a bearing portion 28 formed integrally with bearing members 27a and 27b attached to the inner surface of the housing 4b. Further, the shaft member 26 also penetrates a bearing portion 40 formed integrally with the inner surface of the door 12. As a result, the door 12 is rotatable about the shaft member 26 between a closed position that closes the insertion port 10 and an open position that tilts toward the inner surface side of the housing 4b and opens the insertion port 10. ing.

One end of the torsion coil spring 25 is hooked to the bearing portion 28, and the other end abuts against the inner surface of the door 12 to urge the door 12 to the closed position. It should be noted that the door 12 is prevented from further rotation by bringing a part of its outer surface into contact with the rear surface of the edge of the notch 10b.
[0039]
Next, the structure of the outer surface of the door 12 will be described with reference to FIG. The outer surface of the door 12 is a surface facing the opposite side of the inside of the housing in which the loading portion 24 is disposed when the door 12 is in a closed position where the insertion port 10 is closed, and the lid 5 is an insertion port forming surface. When 9 is opened, the surface is exposed to the outside of the housing 4.
[0040]
As shown in FIG. 6, a step portion 50 is formed on the outer surface of the door 12. The step part 50 consists of several recessed parts. Specifically, flat portions 31a and 31b that are recessed in the thickness direction from the outer surface of the edge of the door 12 are formed at both ends in the longitudinal direction, and the thickness is further thicker than the flat portions 31a and 31b. The flat portions 34a and 34b that are recessed in the direction are connected via the slope portions 32a and 32b. A flat surface portion 33 that is substantially flush with the flat surface portions 34a and 34b is formed between the flat surface portions 34a and 34b with ribs 35a and 35b interposed therebetween.
[0041]
Each plane part 31a, 31b, 34a, 34b, 33 is divided | segmented into plurality by slope part 32a, 32b and rib 35a, 35b, and is discontinuous regarding the longitudinal direction of the door 12. FIG.
[0042]
The ribs 35a and 35b extend in a direction perpendicular to the longitudinal direction of the door 12, and separate the concave portion having the flat surface portions 34a and 34b as the bottom surface and the concave portion having the flat surface portion 33 as the bottom surface.
[0043]
In each concave portion, the side wall surface formed on the side opposite to the hinge mechanism functions as a damming portion that prevents water droplets from dropping to the loading portion 24 side when the door 12 is tilted.
[0044]
Further, water absorbing materials 30a to 30c are laid on each of the plane portions 31a, 31b, 34a, 34b, 33 and the slope portions 32a, 32b. The water absorbing material 30a is attached so as to be along the flat surface portion 31a, the slope portion 32a, and the flat surface portion 34a, and the water absorbing material 30c is attached so as to be along the flat surface portion 31b, the inclined surface portion 32b, and the flat surface portion 34b, The water absorbing material 30b is stuck along the flat portion 33.
[0045]

For example, polyester fibers, acrylic fibers, and polyurethane resins mixed at a mixture ratio of 54%, 40%, and 6% are used. For example, the cloth thickness is 0.43 ± 0.05 mm (measurement method is JIS L-1096 compression elastic method, initial load 7 g / cm ² ). The basis weight is 105.0 ± 5% (measurement method is JIS L-1096, apparent weight standard state).
[0046]
(Operation of inserting the disk cartridge 8 from the insertion slot 10)
When the eject button 6 formed on the upper surface casing 4a is pushed from the state in which the lid 5 shown in FIG. 1 is closed, the engagement between the lock members 58a and 58b and the lid 5 shown in FIG. The insertion port forming surface 9 is opened by a biasing force of a torsion coil spring (not shown).
[0047]
As shown in FIG. 3, the disc cartridge 8 is inserted from the insertion port 10 with the insertion side end surface of the disc cartridge 8 abutting against the outer surface of the door 12. At this time, the outer surface of the door 12 is pushed by the disc cartridge 8 and tilts toward the loading portion 24 around the hinge mechanism against the biasing force of the torsion coil spring 25 shown in FIG. 10 allows the disc cartridge 8 to be inserted.
[0048]
Here, as described above, the outer surface of the door 12 is not flush with each other, and a plurality of recesses are formed. Therefore, the loading unit 24 that is the direction in which water drops fall in a state where the door 12 shown in FIG. 7 is tilted. A side wall portion of the recess exists in the direction toward the side. As a result, even if the water droplet a adheres to the outer surface when the door 12 is in the closed position and is tilted in that state, the water droplet a can be dammed at the side wall portion of the recess. The fall to the part 24 side can be prevented. As a result, failure or malfunction of the optical pickup and other electronic components due to the ingress of water droplets can be prevented.
[0049]
Further, the ribs 35a and 35b can prevent water droplets from moving from the other surface of the door 12 to the central portion, and prevent a large amount of water droplets from accumulating in the central portion. In the loading unit 24, an optical pickup, a semiconductor laser, and the like are arranged in the center portion in the longitudinal direction of the door 12. By the above, an optical component such as an optical pickup that is most susceptible to water droplets and electronic components are reliably secured in the loading unit 24. Can protect from water drops.
[0050]
Further, when the water droplets a adhere to the outer surface of the door 12 by the water absorbing materials 30a to 30c, the water droplets a are immediately absorbed and are prevented from dropping into the loading portion 24. Alternatively, the water absorbing material 30a to 30c absorbs the water droplet a while the water droplet a is dropped at the stepped portion 50, so that the damming action at the stepped portion 50 and the water absorbing action by the water absorbing materials 30a to 30c are absorbed. With the synergistic effect, it is possible to reliably prevent water droplets from dropping onto the loading unit 24.
[0051]
The embodiment of the present invention has been described above. Of course, the present invention is not limited to this, and various modifications can be made based on the technical idea of the present invention.
[0052]
The outer surface shape of the door 12 may be smooth and the water absorbing material may be provided thereon. Even if there is no step for blocking the water droplets, the water droplets on the outer surface are absorbed by the water absorbing material, so that the water droplets can be prevented from falling to the loading portion 24.
[0053]
In addition, if the amount of water droplets is very small, it is effective to prevent the water droplets from dropping onto the loading portion 24 even if only the step portion is formed without providing a water absorbing material.
[0054]
The stepped portion and the water absorbing material do not need to be entirely present on the outer surface of the door 12, and may be partial, for example, provided only at a portion corresponding to the pickup arrangement position in the loading portion 24.
[0055]
【The invention's effect】
As described above, according to the present invention, the water droplet dropping prevention means for preventing the water droplet from dropping when tilting is provided on the outer surface of the door that opens and closes the insertion port. Prevents intrusion, and prevents malfunction and failure of the parts themselves.
