Next, the series of processes from insertion of the card 2 into the main body of the system of the first embodiment to removal of the card 2 will be described in a second embodiment.
This will be explained with reference to FIG. 2(a) to FIG. 2(d). Second
In Figures (a) to 2(d), the same parts as in Figure 1 are given the same reference numerals.

First, as shown in FIG. 2(a), a locking mechanism 13 composed of, for example, a spring 10, a rod 11, and a claw portion 12 is provided inside the main body device 1. As shown in FIG.

The claw portion 12 is always protruded to the side of the entry port 3 by the pushing force of the spring 10.

Furthermore, a lock release mechanism 14 is also provided inside the main body device 1 . The lock release mechanism 14 communicates with the outside via the keyhole 6. The lock release mechanism 14 is the lock mechanism 1
3 and are connected to each other by the rod 10. stick 1
0 has a function of transmitting this operation to the lock mechanism 13 when the lock release mechanism 14 is driven, that is, performs a release operation.

Next, as shown in FIG. 2(b), the card 2 is inserted into the main device 1 through the insertion slot 3. At this time, the claw portion 1
2 is pressed against the side wall of the card 2, the spring 10 is compressed.

Next, as shown in FIG. 2(c), as the pushing operation further progresses, the position of the claw portion 12 comes to the position of the locked portion of the card 2, that is, the position of the notch portion 4. Then, the claw portion 12 is housed in the notch portion 4 by the force of the spring 10 extending.

In this way, the claw portion 1 of the lock mechanism 13 inside the main device 1
2 is stored in the notch 4 of the card 2, so that the card 2 is locked with respect to the main device 1.

Therefore, the card 2 cannot be taken out from inside the main device 1.

To release this locked state, a key 5 is required, as shown in FIG. 2(d). This key 5 is inserted into the lock release mechanism 14 through the keyhole 6.

Only when this key 5 can drive the lock release mechanism 14, that is, can release the locked state, will the lock release mechanism 14 be able to operate the key 5 (for example, as indicated by the arrow 15 in the figure). The release operation is performed in response to the direction of rotation.

This release operation is transmitted to the lock mechanism 13 via the rod 10, and the claw portion 12 is driven in conjunction with this. For example, as shown in the figure, when the rod 10 is pulled inward of the lock release mechanism 14, the claw portion 12 is moved into the notch portion 4.
come out from inside.

In this way, the claw portion 1 of the lock mechanism 13 inside the main device 1
2 comes out of the notch 4 of the card 2, the locked state is released.

Therefore, the card 2 can be taken out from inside the main device.

In this way, only those who have the key 5 that can unlock the lock release mechanism 14 can take out the card 2.

Therefore, accidental theft of the card 2 can be prevented.

FIG. 3 shows an information recording medium lock according to the second embodiment.
1 is a schematic perspective view of a device with a system; FIG. In FIG. 3, the same parts as in FIG. 1 are given the same reference numerals, and overlapping explanations are avoided.

As shown in FIG. 3, the second embodiment is characterized in that a lock release mechanism (not shown) is provided inside the card 2 instead of inside the main device 1.

Therefore, as shown in the figure, a keyhole 6 communicating with the unlocking mechanism from the outside is provided in the card 2.

Of course, even in this case, the same effects as in the first embodiment can be obtained.

Next, the series of processes from insertion of the card 2 into the main body of the system of the second embodiment to removal of the card 2 will be explained in the fourth embodiment.
This will be explained with reference to FIG. 4(a) to FIG. 4(d). Fourth
In Figures (a) to 4(d), the same parts as in Figures 2(a) to 2(d) are given the same reference numerals.

First, as shown in FIG. 4(a), in the second embodiment,
The lock release mechanism 14 is not inside the main device 1. Therefore,
The locking mechanism 13 does not require the rod 10 that connects it and the unlocking mechanism 14 to each other.

Therefore, in the case of the second embodiment, the locking mechanism 13 is
It is composed of a spring 10 and a claw part 2.

On the other hand, the card 2 is newly equipped with a lock release mechanism 14. Since the card 2 is equipped with a lock release mechanism 14, a keyhole 6 is newly provided to communicate this with the outside.

This lock release mechanism 14 is a member that is substantially a part of the lock release mechanism 14, and is always stopped by a spring 16 so as not to protrude into the notch 4, and is connected to the lock release mechanism by a rod 17. A plate 18 is provided.

Next, as shown in FIG. 4(b), like the first embodiment, the card 2 is inserted into the main unit 1 from insertion 03.

At this time, the spring 10 is compressed by the claw portion 12 being pressed against the side wall of the card 2.

Next, as shown in FIG. 4(C), as the insertion operation further progresses, the position of the claw portion 12 comes to the locked portion of the card 2, that is, the position of the notch portion 4. Then, the card 2 is locked with respect to the main device 1.

Next, as shown in FIG. 4(d), the key 5 is inserted into the unlocking mechanism 14 through the keyhole 6, as in the first embodiment.

Only when this key 5 can drive the lock release mechanism 14, that is, can release the locked state, will the lock release mechanism 14 be able to operate the key 5 (for example, as indicated by the arrow 19 in the figure). The release operation is performed in response to the direction in which the vehicle moves forward.

This release action is transmitted via the rod 17 to the plate 18 attached to the tip thereof, thereby driving the plate 18. For example, as shown in the figure, the rod 17 is pushed out of the lock release mechanism 14, the plate 18 pushes the claw 12, and the claw 12 is pushed out of the notch 4.

In this way, the claw portion 1 of the lock mechanism 13 inside the main device 1
2 comes out of the notch 4 of the card 2, the locked state is released as in the first embodiment.

Therefore, the card 2 can be taken out from inside the main device 1.
