Description

[Detailed Description of the Invention] The present invention relates to a tape cassette adapter used, for example, when attaching a tape cassette smaller than a standard type to a standard type recording/reproducing machine, and the small tape cassette is attached to the adapter. By providing a mechanism to prevent incorrect attachment of the adapter, which allows the adapter to be attached to the recorder/player only when the adapter is attached to the recorder/player, it will be wasteful if an adapter without a small cassette is attached to the recorder/player and attempts are made to record/play back. To provide an adapter for a tape cassette that will not become damaged if it is operated incorrectly.

FIG. 1 is a schematic perspective view of one embodiment of a tape cassette adapter according to the present invention, and FIGS. 2 and 3 are explanatory diagrams of the operation of essential parts in a cross section taken along line A--A in FIG.

In the figure, A is an adapter whose external shape is approximately the same as that of a standard type tape cassette;
The is configured with a storage section A' into which a tape cassette B, which is smaller than the standard type tape cassette, can be installed.The small tape cassette B can be installed in the storage section A', and the tape can be pulled out from the small tape cassette. , in case of a rear collision where the tape path is almost the same as that of a standard type tape cassette, if this adapter is attached to a standard type recording/playback machine, it will be possible to record/play back a standard type that is not specially designed for small tape cassettes. It is constructed so that it can be recorded and played back even on a machine.

Reference numeral 1 denotes a push button protrudingly provided on the top surface of this adapter A. Press the push button 1 to release the push button 1.
When the top of push button 1 becomes flush with the top surface of adapter A, or when the top of push button 1 becomes recessed from the top surface of adapter A, the small tape cassette B placed in storage area A' of adapter A is completely attached to the adapter. , the magnetic tape is pulled out from a small tape cassette B to form a predetermined tape path. An elastic material 2 such as a coil spring is provided at the bottom of the push button 1, which always urges the push button 1 upward. An elastic locking piece 3 is provided which is biased in the direction, and when the push button 1 is pushed into the adapter, the elastic locking piece 3 locks into the hole 4 of the adapter A and locks. Even with the resilient material 2, the push button 1 is not restored to its original state.

A lock release button 6 is disposed in the hole 4 and is always urged outward, that is, in the right direction in FIGS. 2 and 3, by an elastic material 5 such as a coil spring. In the state shown in FIG. 3, if the lock release button 6 is pressed to the left, that is, the lock release button 6 is pressed by applying a force that resists the repulsive force of the elastic body engaging piece 3 and the repulsive force of the elastic material 5. Then, the tip of the lock release button 6 opens the hole 4 of the elastic body locking piece 3.
The push button 1 is released from the lock, and the push button 1 is pushed up by the force of the elastic material 2, and becomes the state shown in FIG.

7 is the storage part of the adapter A through the cavity 8.
This is the tongue portion of the push button 1 protruding from A', and this tongue portion 7 is configured to move up and down as the push button 1 moves up and down.

Then, the installation of the small tape cassette is done in the second step.
As shown in FIG. 3 and FIG. 3, when a small tape cassette B is placed on the tongue portion 7 of the storage section A' of the adapter A and the push button 1 is pressed, the small tape cassette B is opened as shown in FIG. is completely installed, and the small tape cassette can be removed by pressing the lock release button 6.
When you press , small tape cassette B will be placed in the storage area.
It will rise above A′ and pop out.

When the tape cassette adapter is configured as described above, a lid etc. is provided on the storage section A', and this lid makes it impossible to tell from the outside whether or not a small tape cassette is attached to the adapter. Even in such a case, if push button 1 is not pressed and is in the state shown in Figure 2, you can immediately recognize that a small tape cassette is not installed, and the recording/playback operation will be interrupted. If you take time to work, you will lose track of time. If push button 1 is not pressed, even if you try to attach the adapter to the recording/playback device, the adapter will not be able to be attached to the recording/playback device because it has a protrusion, so you should avoid unnecessary recording/playback operations. Become.

Furthermore, the small tape cassette can be attached and removed simply by operating a button, making handling of the small tape cassette extremely easy and smooth.

FIG. 4 is an explanatory diagram of another embodiment of the tape cassette adapter according to the present invention, FIGS.
Figure 6 a, b is the C-C line section in Figure 5 a, b, D-
FIG. 4 is an explanatory diagram of the operation of the main part in a cross section taken along line D;

In the figure, C is the adapter A in the above embodiment.
It is an adapter with a similar external shape, and this adapter C
A storage section C' similar to the storage section A' of the adapter A is configured.

11 is a push button, 12 is a tongue piece provided at the bottom of the push button 11 and protrudes into the storage part C' through a substantially square-shaped cavity 13, and 14 is a coil spring that always biases the push button 11 upward. It is an elastic material such as.

Then, as shown in FIG. 4, the small tape cassette D is now placed on the tongue part 12 of the storage part C', the push button 11 is pushed in, and then the push button 11 is moved in the direction of the arrow to release the tongue part 12. itself becomes latched to the wall of the adapter and becomes locked, the small tape cassette D is completely stored in the storage section C', and the small tape cassette D is completely installed.
Also, to remove the small tape cassette D, move the push button 11 in the direction opposite to the direction of the arrow, and the tongue piece 12
At the same time as the push button 11 is released from the latching state, the push button 11 is lifted up by the elastic material 14, and the small tape cassette D is also lifted up by the tongue piece 12.

As described above, the tape cassette adapter of the present invention is an adapter for storing a tape cassette smaller than a standard type tape cassette and for use when attached to a standard type recording or playback machine, and is provided with a push button that can be protruded or retracted from the surface of the adapter depending on the storage state of the small tape cassette. When the small tape cassette is not stored in the adapter, the push button protrudes from the surface side of the adapter, thereby preventing the adapter from being attached to a standard type recording or playback machine, and when the small tape cassette is stored in the adapter, the push button is retracted from the surface of the adapter, thereby enabling the adapter to be attached to a recording or playback machine.
The present invention has the following features: it eliminates the need for unnecessary operations such as mounting an adapter without a small tape cassette on a recording/reproducing machine to perform recording/reproducing operations, and enables smooth operation of recording/reproducing with a small cassette on a non-dedicated standard type recording/reproducing machine.
