Hereinafter, the operation of each component described with reference to FIG. 4 will be described. First, the operation when the cartridge 15 is mounted in the optical disk video camera 1 will be described. FIG. 5 is a top view in a state where the cartridge 15 is normally inserted into the cartridge holder 16. In addition,
Illustration of the mechanical chassis 17 is omitted.

Lock pin 201A and lock pin 201B
Is shorter than the width W of the cartridge 15,
With the insertion of the cartridge 15, the lock pin 201A
The distance between the lock pin 201B and L increases from L to L '. That is, as the cartridge 15 is inserted, the lock pins 201A and 201B come into contact with the corners of the cartridge 15 and are guided by the rounded corners.
0A rotates about the shaft 204A, and the lock arm 20B
Is rotated about the shaft 204B, so that the lock pin 20 is rotated.
The distance between 1A and the lock pin 201B becomes L '. Further, with the rotation of the lock arms 20A, 20B, the coil springs 24A, 24B extend, and apply a force to return the distance L 'between the lock pin 201A and the lock pin 201B to the distance L to the lock arms 20A, 20B. .

On the other hand, although not shown, the cartridge 1
When the lock pin 201 is inserted from the opposite direction,
A and 201B come into contact with the corners of the cartridge 15 and are guided by the rounded corners, so that the lock arms 20A and 20B are locked.
B rotates around the shafts 204A and 204B and returns to the original position by the coil springs 24A and 24B (elastic force).
Is given. Thereafter, when the lock pin 201B reaches the notch 153A and the lock pin 201A reaches the notch 153B, the lock arms 20A and 20B return to their original positions and are locked by the lock pins 201A and 201B being located in the notches. That is, the lock pin 201
A and 201B prevent the cartridge 15 from being erroneously inserted. The notches 153A and 153B are formed such that the shutter 151 side is cut substantially perpendicular to the cartridge insertion direction, and the opposite side is cut with an inclination. Therefore, the lock pin once rotated is surely guided into the notch, and the lock pin guided into the notch is disengaged from the notch, thereby preventing further insertion of the cartridge. Further, by making the line connecting the shafts 204A, 204B and the lock pins 201A, 201B substantially parallel to the cartridge insertion direction, it is possible to reduce the possibility that the lock pin once located in the notch comes off from the inside of the notch. it can.

FIG. 6 is a bottom view in a state where the cartridge 15 is normally inserted into the cartridge holder 16.
The illustration of the mechanical chassis 17 is omitted.

As shown, the torsion coil spring 1
With 69, the rotation arm 163 is biased, and the shutter opener 162 is located at a position where it comes into contact with the end of the shutter 151.

Here, the advantage of using the shutter opener 162 and the rotating arm 163 as separate members will be described. FIG. 7 is a bottom view showing a structure in which the functions of the shutter opener 162 and the rotating arm 163 can be realized by one member. In the figure, structures having the same functions as those shown in FIG. 6 are denoted by the same reference numerals.

The shutter opener 162 'is rotatably supported on the upper surface of the cartridge holder 16', and is urged to the position shown in FIG. 7 by an elastic member. The cartridge holder 16 ′ has a structure in which the projection of the shutter opener 162 ′ is hooked on the recess of the shutter 151 by inserting the cartridge 15, and holds the cartridge 15 in a state where the shutter 151 is opened by pushing the cartridge.

This structure differs from the structure shown in FIGS. 5 and 6 in that the shutter opener 1 is used to secure a stroke necessary for the shutter 151 to open.
Reference numeral 62 'denotes a point at which the shutter 151 abuts at the center, not at the end, and a point at which the shutter opener 162' and the shutter 151 start to abut, which are closer to the shutter insertion port than the positions shown in FIGS. It is. That is, in the structure of FIGS. 5 and 6, the shutter opener 162 '
When the position at which the shutter 151 and the shutter 151 start contacting is viewed from the insertion direction of the cartridge 15, the disk can be located deeper than the clamper that sandwiches the disk together with the turntable. Therefore, the amount of protrusion of the cartridge when the disc is ejected can be reduced, and the space for the cartridge attaching / detaching mechanism can be reduced.

Returning to the description of the operation of each component described with reference to FIG. FIG. 8 is a perspective view of the mechanical unit 14 in a state in which the cartridge 15 inserted from the cartridge insertion slot is pushed into the optical disk video camera 1 and the optical disk 156 can record and reproduce data such as video and audio. It is. FIG. 9 is a right side view of the mechanical unit 14 in the state shown in FIG. 8, and FIG. 10 is a bottom view of the mechanical unit 14 in the state shown in FIG. In FIG. 10, the mechanical chassis 17 is omitted.

When the cartridge 15 is pushed in from the state shown in FIGS. 5 and 6, the lock pins 201A and 201B are located at the notches 153A and 153B, respectively. At this time, since the lock arms 20A and 20B that have been rotated around the shafts 204A and 204B are released by the coil springs 24A and 24B, the lock arms 201A and 24B are released.
A, 201B are located in notches 153A, 153B.

The shutter opener 162 is guided by the guide hole 167 while contacting the end of the shutter 151, and moves from the position shown in FIGS. 5 and 6 to the position shown in FIGS. 8, 9 and 10. Then, the shutter 151 is opened. Note that the pivot arm 163 pivots from the position shown in FIGS. 5 and 6 to the position shown in FIGS. 8, 9 and 10 as the shutter opener 162 moves.

Accordingly, the cartridge holder 16 is configured to withstand the force by which the lock pins 201A and 202B return (close) to the original position of the shutter 151.
The cartridge 15 is held at a position where information can be recorded on or reproduced from the optical disc 156.

When the cartridge holder 16 holds the cartridge 15 at a position where information can be recorded on or reproduced from the optical disk 156, the plate springs 252A, 252 of the engaging members 25A, 25B are held.
B engages recesses 154A, 154B. The engaging members 25A and 25B are given a force by the coil springs 26A and 26B to return from the positions shown in FIGS. 8, 9 and 10 to the positions shown in FIGS.

After the cartridge holder 16 holds the cartridge 15 at a position where information can be recorded or reproduced with respect to the optical disk 156, the disk cover 5 is closed to close the cartridge holder 16 and the clamp holder 18. Pivots from the position shown in FIGS. 5 and 6 to the position shown in FIGS. 8, 9 and 10. At this time, the clamp holder 18 holds the clamper 1
81 rotates to a position where the optical disk can be sandwiched together with the turntable, and the clamper 181 sandwiches the optical disk 156 together with the turntable. While the clamp holder 18 rotates as described above, the release arm 182 contacts the hook 23,
The bending of the release arm 182 and the hook 23
Is released, so that the clamper 181 can finally sandwich the optical disc 156 together with the turntable. Also, the pins 171A, 171B
(Not shown in FIGS. 8, 9 and 10) are inserted into the positioning holes 152A and 152B. Even if the erroneous insertion prevention mechanism by the lock pins 201A and 201B does not work, the cartridge holder 16 is moved to the position shown in FIGS. It will not pivot to the position shown. In this sense, the pin 171A,
171B also has a role of preventing erroneous insertion of the cartridge 15.

Next, the operation for removing the cartridge 15 mounted in the optical disk video camera 1 will be described. FIG. 11 is a perspective view of the mechanical unit 14 in a state where the cartridge 15 mounted in the optical disk video camera 1 can be taken out. FIG.
FIG. 12 is a right side view of the mechanical unit 14 in the state shown in FIG. In the description of FIG. 11 and FIG.
The counterclockwise direction is as shown in FIG.

When the disk cover 5 is opened, the cartridge holder 16 and the clamp holder 18 rotate from the positions shown in FIGS. 8, 9 and 10, and thereafter, only the clamp holder 18 further rotates, and FIG. And the position shown in FIG. If the cartridge holder 16 and the clamp holder 18 are rotated only after the clamp holder 18 is rotated, in the worst case, the cartridge holder 16 and the clamp holder 1 may be rotated.
Before rotating the cartridge 8, the holding state of the cartridge 15 by the lock pins 201A and 201B is released, and there is a possibility that the cartridge cannot be removed from the optical disc video camera 1. As described above, the cartridge holder 16 and the clamp holder 18 are rotated from the positions shown in FIGS. 8, 9 and 10, and thereafter, only the clamp holder 18 is further rotated. Before the rotation of the lock pin 201
Even if the holding state of the cartridge 15 by A and 201B is released, the clamper 181 is caught by the cartridge 15, so that the cartridge holder 16 can be reliably rotated, and the cartridge 15 can be taken out from the optical disc video camera 1.

When the cartridge holder 16 and the clamp holder 18 are rotated from the positions shown in FIGS. 8, 9 and 10, and then only the clamp holder 18 is further rotated, the release arm 182 comes into contact with the hook 23,
The lock release arm 21B rotates clockwise about the shaft 214B. With this rotation, the contact portion 212B rotates clockwise, contacts the protrusion 212A, rotates the lock release arm 21A counterclockwise, and rotates the contact portion 211B clockwise. Then, the lock arm 20B is rotated counterclockwise in contact with the projection 202B. Further, since the lock release arm 21A rotates counterclockwise, the contact portion 211A contacts the protrusion 202A, and the lock arm 20A rotates clockwise.

That is, when the cartridge holder 16 and the clamp holder 18 are rotated from the positions shown in FIGS. 8, 9 and 10, and then only the clamp holder 18 is further rotated, the lock pins 201A and 201B are notched. Since the cartridges 153A and 153B are separated from each other, the holding state of the cartridge 15 by the cartridge holder 16 is released.

When the holding state of the cartridge 15 by the cartridge holder 16 is released, the shutter 151 is released.
The cartridge 15 is moved to the position shown in FIGS. 11 and 12 by the force of returning to the original position (the force of closing), and is discharged. At this time, the concave portions 154A, 154B
The engagement members 25A and 25B engaged with the cartridge 15 also move with the cartridge 15 while maintaining the engagement state with the cartridge 15.

The engagement members 25A and 25B have a role of reducing the amount of protrusion of the cartridge 15 when the cartridge 15 is ejected. If there is no engaging member having such a role, there is no means for attenuating the force for returning the shutter 151 to the original position (the force for closing), and the cartridge 15 pops out and falls from the optical disk video camera 1. It is very likely that Also, even if it has an engaging member having such a role,
If the engaging member is fixed with respect to the cartridge discharging direction, it loses the force for returning the shutter 151 to the original position (the force for closing), that is, the pop-up speed of the cartridge 15 with respect to the engaging member. Is large, the engagement state is released, and eventually the cartridge 15 jumps out and falls from the optical disc video camera 1. By attaching the engaging member movably in the cartridge discharge direction as in the present embodiment,
The above-described problem can be solved, and the possibility that the cartridge 15 drops from the optical disc video camera 1 can be reduced.

In the present embodiment, the coil springs 26A, 26
B is provided to reduce the relative speed with respect to the ejecting speed of the cartridge 15 by applying a force for moving the engaging member in the cartridge discharging direction. Power to try)
It goes without saying that the coil springs 26A and 26B are unnecessary depending on the situation.

As described above, the engagement member 25 includes
Since the rectangular holes 253 and 254 are provided, the moving range thereof can be regulated, and the amount of the cartridge 15 protruding can be regulated. Also, as described above, the amount of protrusion of the cartridge 15 can be reduced by using the shutter opener 162 and the rotating arm 163 as separate members.

After the operation described above, the cartridge 1
5 moves to the state shown in FIG. 11 and FIG. The engaging members 25A and 25B are plate springs 252A and 252 having elasticity in a direction substantially perpendicular to the cartridge discharging direction.
Since the cartridge 15 is engaged with the cartridge 15 by 52B, the user can easily remove the cartridge 15 from the optical disk video camera 1 by pulling the cartridge 15.

Note that the rotation of the lock release arm 21B eventually causes the release arm 182 and the hook 2
Since the contact state with the lock arms 20A, 2B is released by the force (elastic force) of returning the coil springs 24A, 24B to the original position after the cartridge 15 is taken out.
0B and the lock release arms 21A and 21B return to the state shown in FIG.

As described above, in the present embodiment, an optical disk video camera has been described as an example of a portable information device. However, the present invention is not limited to an optical disk video camera, but may be an MD or a viewer. It goes without saying that the present invention can be applied to other portable information devices.
