[Patent Document 2]
JP 2001-101675 A
In a disk device provided in such a camera, in order to minimize exposure of the inside of the main body when the disk cartridge is inserted and removed, a configuration in which the disk cartridge is inserted and removed through an elongated insertion port opened in a housing is usually used. Well adopted. A door is provided at the insertion opening to open and close the insertion opening.
[0006]
As shown in FIG. 7, such a door 52 is attached to the housing 54 via a hinge mechanism h, and is urged by a torsion coil spring (not shown) to a closed position where the insertion port 10 is closed. When the disc cartridge 8 is inserted, the disc cartridge 8 is pushed by the disc cartridge 8 and tilts into the housing 54 to enable the disc cartridge 8 to be inserted from the insertion slot 10.
[0007]
[Problems to be solved by the invention]
A loader 20 is provided inside the housing 54 as holding means for loading the disk cartridge 8 into the loading section. The loader 20 can be moved up and down and left and right inside the housing 54. Therefore, in order to enable the movement of the loader 20, a space larger than the width (length in the short direction) of the insertion port 10 is formed below the insertion port 10, and the insertion from the insertion port 10 is performed as illustrated. The disk cartridge 8 is configured to allow a large inclination.
[0008]
In such a structure, conventionally, the degree of tilt of the door 52 is not limited, and the door 52 can tilt until the inner surface of the door 52 contacts the inner wall surface of the housing 54. In this case, as shown in FIG. 7, the insertion of the disk cartridge 8 with a large inclination is permitted, and a large load is applied to the disk cartridge 8 and the loader 20. In some cases, loading failure of the disk cartridge 8 may occur.
[0009]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to provide a disk device in which a door has a function of promoting insertion of a disk cartridge in an appropriate posture, and a camera including the disk device. To provide.
[0010]
[Means for Solving the Problems]
In order to solve the above problems, in the disk device of the present invention, the door for opening and closing the insertion opening opened in the housing is tilted, and the loading unit disposed inside the housing at the closed position is closed. A stopper member that regulates the degree of tilt of the door is interposed between the inner surface of the door that is turned and the inner wall surface inside the housing that faces the inner surface.
[0011]
The stopper member restricts the degree of tilting of the door, so that an unnecessarily large space is not formed immediately below the insertion slot so as to allow a large inclination of the disk cartridge inserted from the insertion slot. This prevents the disc cartridge from being inserted from the insertion port in a state of being largely inclined, thereby preventing improper loading. Further, if the disc cartridge is inserted into the outer surface of the door having a limited degree of tilting while the end of the disc cartridge is in contact with the door, a smooth guiding action of the disc cartridge inserting operation in an appropriate posture can be obtained.
[0012]
The stopper member may be provided on the inner wall surface of the housing, or may be provided on the inner surface of the door. However, if the door is provided on the inner surface of the door, the door is tilted integrally with the stopper member between the closed position and the open position. It is necessary to avoid interference with components.
[0013]
If the stopper member is provided on the inner wall surface of the housing so as to be able to contact the inner surface of the door to be tilted, the stopper member remains fixed to the housing when the door is tilted. In this case, only a space that allows only the door to tilt may be secured.
[0014]
Further, in the disk device of the present invention, holding means for holding a disk cartridge inserted from the insertion slot is provided inside the housing, and the tilting of the door is restricted in a state where the tilting of the door is restricted by the stopper member. The door is tilted such that the tip of the door opposite to the center is located on the holding means.
[0015]
In such a configuration, since the outer surface of the tilted door is inclined toward the holding means side, if the disk cartridge is inserted along the end of the disc cartridge along the inclined surface, the disc cartridge is smoothly moved to the holding means. Can be led to. As a result, improper loading of the disk cartridge can be prevented, and a large load can be prevented from being applied to the disk cartridge and the holding means.
[0016]
A camera according to the present invention includes the above-described disk device. That is, in the camera of the present invention, the captured data can be recorded on the disk-shaped recording medium in the disk cartridge loaded in the loading section of the disk device.
[0017]
Further, the disk cartridge in the present invention 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. Also, there is included a magnetic disk having a structure in which one or a plurality of magnetic disks are accommodated in a casing and a magnetic head for reading and writing the magnetic disks (so-called portable hard disk).
[0018]

(Structure near the insertion port)
FIG. 2 shows a perspective view near the insertion port 10. At a connection portion between the upper housing 4a and the right housing 4b of the camera body 3, an insertion opening forming surface 9 recessed from the other outer surfaces of these housings 4a, 4b is formed. An insertion port 10 that extends in the front-rear direction of the camera body 3 is opened in the insertion port forming surface 9.
[0024]
The right side case 4b is attached to the upper side case 4a by, for example, screwing. At this time, a substantially U-shaped notch 10a formed in the upper side case 4a and a right side case 4b are formed. By making the notches 10b of substantially U-shape face each other, a substantially rectangular insertion opening 10 is obtained.
[0025]
The length of the insertion slot 10 is slightly larger than the width of the disc cartridge 8 to be inserted, and the width of the insertion slot 10 is slightly larger than the thickness of the disc cartridge 8. Can be inserted into or removed from the loading section 24.
[0026]
(Lid structure)
In the right side housing 4b, a closed position (the state of FIG. 1) covering the entire insertion opening forming surface 9 including the insertion opening 10 and an open position (the state of FIG. 2) where the insertion opening 10 and the insertion opening forming surface 9 are opened. ) Is attached. One end of a hinge 11a penetrating the right side housing 4b is connected to the inner surface of the lid 5 facing the insertion opening forming surface 9. The lid 5 is urged by a torsion coil spring (not shown) in a direction to open the insertion port forming surface 9.
[0027]
L-shaped lock members 58a and 58b are provided at positions closer to the inside on the insertion opening forming surface 9, and the lock members 58a are provided on the inner surface of the lid 5 when the lid 5 is in the closed position. , 58b are attached.
[0028]
(Door structure)
FIG. 5 shows the inner surface side (the side facing the loading section 24) of the right side housing 4b. On the back surface of the edge of the U-shaped notch 10b that constitutes half of the insertion slot 10, a size larger than the size of the insertion slot 10 is provided via a hinge mechanism including a shaft member 26, a torsion coil spring 25, and the like. A rectangular door 12 is attached.
[0029]
The shaft member 26 extends along the longitudinal direction of the door 12 and penetrates a bearing 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 integrally formed on the inner surface of the door 12. Thus, the door 12 is rotatable around the shaft member 26 between a closed position for closing the insertion opening 10 and an open position for tilting inward of the housing 4b to open the insertion opening 10. ing.
[0030]
In the shaft member 26, a torsion coil spring 25 is wound around a portion between the two bearing portions 28 of the bearing member 27a. One end of the torsion coil spring 25 is hooked on the bearing portion 28, and the other end contacts the inner surface of the door 12 to urge the door 12 to the closed position. Further, the door 12 has a part of the edge on the outer surface thereof abutted against the rear surface of the edge of the notch 10b, so that further rotation is restricted.
[0031]
Further, on the inner surface of the housing 4b, between the bearing members 27a, 27b, two stopper members 30a, 30b are provided as ribs protruding from the inner surface of the housing 4b.
[0032]
As shown in FIG. 6, the stopper members 30 a and 30 b have a trapezoidal cross-section (or a trapezoidal shape in which the protrusion thickness is gradually increased in a direction from the insertion port 10 toward the loader 20 disposed below the insertion port 10. Triangular shape).
[0033]
The loader 20 functions as a holding unit that holds the disk cartridge 8 inserted from the insertion slot 10 and loads the disk cartridge 8 into the loading unit 24. The loader 20 is movable in the up-down direction and the left-right direction (a direction approaching or leaving the chucking table 19 of the loading unit 24). Therefore, a space that allows the movement of the loader 20 is secured in the housing 4b, and a space that is larger than the opening area of the insertion port 10 exists below the insertion port 10.
[0034]
Since the stopper members 30a and 30b have a trapezoidal cross section in the direction from the insertion opening 10 to the loader 20, the portions of the stopper members 30a and 30b that abut against the inner surface of the door 12 are vertically aligned with the loader 20. It has a slope inclined to the side.
[0035]
As a result, the tip of the door 12 (the end opposite to the hinge mechanism) is located on the loader 20 away from the inner wall surface of the housing 4b.
[0036]
(Operation for Inserting Disc Cartridge 8 from Insertion Slot 10)
When the removal button 6 formed on the upper housing 4a is pressed from the state where the lid 5 shown in FIG. 1 is closed, the engagement between the locking members 58a and 58b and the lid 5 shown in FIG. The insertion port forming surface 9 is opened by the urging force of a not-shown torsion coil spring.
[0037]
Then, as shown in FIG. 3, the end of the disk cartridge 8 is brought into contact with the outer surface of the door 12 and the disk cartridge 8 is inserted from the insertion slot 10. The outer surface of the door 12 is pushed by the end of the disk cartridge 8 and tilts toward the inside of the housing 4b around the shaft member 26 against the urging force of the torsion coil spring 25 shown in FIG. As a result, the insertion slot 10 is opened, and the insertion of the disc cartridge 8 from the insertion slot 10 becomes possible.
[0038]
At this time, as shown in FIG. 6, the inner surface of the tilted door 12 abuts against the inclined surface of the stopper member 30a (30b), and further tilting of the door 12 is restricted. Accordingly, the movement of the end of the disk cartridge 8 that is in contact with the outer surface of the door 12 toward the inner wall surface of the housing 4b is restricted, and the inclination of the disk cartridge 8 can be suppressed.
[0039]
Further, the end of the disk cartridge 8 changes its contact position on the outer surface of the door 12 in the order indicated by the dashed line, the two-dot chain line, and the solid line in FIG. The outer surface of the door 12 is inclined toward the loader 20 along the inclined surface of the stopper member 30a (30b), so that the end of the disk cartridge 8 contacts the outer surface of the inclined door 12. By inserting the disk cartridge 8 into the disk cartridge 8 as it is inserted, the posture of the disk cartridge 8 is corrected so that the disk cartridge 8 can be set up in a nearly vertical posture.
[0040]
As a result, a smooth insertion operation of the disk cartridge 8 can be performed without causing a positional shift with respect to the loader 20 and without applying a large load to the loader 20 in an oblique posture.
[0041]
