Abstract

PROBLEM TO BE SOLVED: To obtain more information data while additional recognition holes and sensors are not added to a tape cassette or a tape cassette device. SOLUTION: The detector 82' of a sensor 80' is longer than the detector 82 of a conventional sensor 80. The recognition hole of a cassette is closed by a cover at a position higher than the opening position. In the closing state of the cassette, the conventional detector 82 can not reach the cover and can not detect the closing state. As the detector 82' of the sensor 80' is longer, the cover at the position higher than the opening position can be detected. With this constitution, exclusive detection can be practiced by using a detection device with the conventional sensor 80 and a detection device with the sensor 80' of this invention.

FIG. 3 shows an example of a conventional and a recognition hole according to the present invention. FIG. 3A shows an example of a closed state of a conventionally used recognition hole. Recognition hole 70 is in the closed state,
The lid 71 is closed immediately near the opening.

FIG. 3B shows an example of a closed state of the recognition hole according to the present invention. The recognition hole 70 is in a closed state and the hole 72 is
Is closed at a predetermined height from the opening position. On the other hand, although not shown, the open state of the hole 70 is common to both the conventional and the present invention.
For example, the hole 70 in the open state is closed at a position higher than the position of the lid 72 or is in an open state. Here, the height of the hole 70 is defined as the height of the hole 7.
0 means the size in the depth direction.

FIG. 4A shows an example of the configuration of a conventionally used recognition hole sensor 80. This is the same as that already described in [Prior Art] (see FIGS. 8 and 9). That is, a detector 82 having a predetermined length is provided at one end of the hole receiving portion 86, and a light shielding portion 83 is provided at the other end of the hole receiving portion 86 via the shaft 81. An optical sensor 85 is provided in the optical sensor unit 84 including two opposing members. The optical sensor 85 includes, for example, a light emitting unit and a light receiving unit provided at corresponding positions of two members.

FIG. 4B shows an example of the configuration of a recognition hole sensor 80 'according to this embodiment. FIG.
Portions common to A are denoted by the same reference numerals, and detailed description is omitted. In the sensor according to one embodiment of this embodiment, the detector 82 'is longer than the conventional detector 82 shown in FIG. 4A. The length of the detector 82 ′ is, for example, the length of the recognition hole 7 according to the present invention described above.
0 corresponds to the height of the lid 72.

The recognition hole 70 according to the present invention
As shown in FIG. 3B, open / close is detected at a higher position than in the related art. Therefore, in the conventional detector 82 shown in FIG.
Does not reach the lid 72 sufficiently or at all. Therefore, the detector 82 cannot detect the state of the recognition hole 70 according to the present invention.

On the other hand, the detector 8 in this embodiment is
2B is longer than the conventional detector 82, so that the lid 72 in FIG. 3B is located at a higher position in FIG. 3B when the tape cassette 6 'according to the present invention is seated.
, And the light blocking portion 83 can be raised so as not to block the optical path of the optical sensor 85. Thereby, the state of the recognition hole 70 can be detected.

Here, the drive having the conventional sensor 80 is referred to as drive A, and the drive having the sensor 80 'according to the embodiment shown in FIG. These drives A and B include a tape cassette 6 (current cassette) having a conventional recognition hole (see FIG. 3A) and a tape cassette 6 'having a recognition hole (see FIG. 3B) according to the present invention.
(Invented cassette) are considered to be seated.

FIG. 5 shows a list of recognition states of the recognition holes 70 at this time. Here, the recognition hole 70 indicates the write protection setting of the tape cassette, and indicates a state in which the write protection is set in the closed state and a state in which the write protection is released in the open state.
In addition, a state in which it is detected that write protection is set and writing is prohibited is detected in “protect”, and “OK”
Indicates a state where it is detected that write protection has been released and writing has been permitted.

As can be seen from FIG. 5, the current cassette is similarly recognized in either of the drives A and B. On the other hand, in the invented cassette, when the recognition holes are closed, drives A and B
, There is a difference in the detection result. That is, in the invented cassette, in the drive A of the conventional specification, it is not detected that the write protection has been released.

By applying this characteristic, the recognition of the tape cassette can be performed exclusively. The current cassette and the drive A are respectively the first generation. Also,
The invented cassette and drive B are each a second generation. In the drive B of the second generation, the write permission state is detected based on the open state of the recognition hole for both the first generation and the second generation cassette. However, when a second-generation cassette is inserted into a first-generation drive, the drive is always in a write-protected state regardless of the state of the recognition hole. As a result, it is possible to always prohibit data writing to the second generation cassette by the first generation drive.
For example, it is possible to prevent an accident that data is erroneously written by the first generation drive to a tape recorded in a format different from that of the first generation by the second generation drive.

Next, a modification of this embodiment will be described. In this modification, the optical sensor unit 84
Optical sensors are provided at two different heights. FIG. 6 shows an example of the configuration of a recognition hole sensor 80 ″ according to this modified example. In FIG. 6, FIGS.
Portions common to those of B are denoted by the same reference numerals, and detailed description is omitted. Thus, in this modification, the optical sensor unit 8
4, two optical sensors 87A and 87B are provided with different heights.

The detector 82 "is longer than the conventional detector 82 of the sensor 80. As will be described later, the detector 82" is formed in the recognition hole 70 of the tape cassette 6 'according to the present invention. When the light sensor 8 is in contact with the lid 72 at a high position,
The length is set to reach only 7A.

By arranging the optical sensors 87A and 87B at appropriate heights, three types of detection can be performed by the recognition hole sensor 80 ″.
A and FIG. 7B show examples of these three types of detection. FIG.
A shows the case where the tape cassette 6 'according to the present invention is combined with the sensor 80 ". In this case, the lid 7 is shown.
Since the hole 2 is at a high position, when the hole 70 is in the closed state, the light blocking portion 83 reaches only the optical sensor 87A.

FIG. 7B shows a case where the current tape cassette 6 is combined with the sensor 80 ″. In this case, since the lid 71 is at a low position, when the hole 70 is in the closed state, The light-shielding part 83 is lifted up to the full level, and the light-shielding part 83 does not reach both the optical sensors 87A and 87B, and although not shown, when both the tape cassettes 6 and 6 'have the hole 70 in the open state, the light-shielding part 83 The light reaches the optical sensor 87B at a lower position.

As described above, according to this modification, by providing two optical sensors 87A and 87B in the optical sensor section 84, the hole 70 of the current cassette in which the lid 71 is at a lower position is provided.
, The closed state of the cassette hole 70 in which the lid 72 is at a high position, and the open state of the cassette hole 70 according to the present invention, can be recognized by one recognition hole sensor 80 ″. .

In the above description, the sensor for detecting the recognition hole is formed using the optical sensor, but this is not limited to this example. For example, a mechanical sensor using a microswitch can be applied to the sensor. Further, a sensor using a magnetic force or the like can be used.

In the above description, the present invention has been described as being applicable to a tape streamer drive and a tape cassette used in the drive, but the present invention is not limited to this example. INDUSTRIAL APPLICABILITY The present invention can be widely applied to many types of tape cassettes, such as a tape cassette used in a home VTR device and a DAT for recording a digital audio signal.

Further, in the above description, the present invention has been described as being applicable to a tape cassette, but the present invention is not limited to this example. The present invention is suitable for use in other forms of recording media contained in a cartridge, such as an MD (Mini Disc), a floppy disk, and a memory card.

[0063]

As described above, according to the present invention, a single recognition hole sensor can recognize a plurality of types of tape cassettes, so that the number of recognition holes provided in the tape cassette can be reduced. There is an effect that can be reduced.

Further, according to the present invention, since the number of the recognition sensors provided on the device side can be reduced, there is an effect that the space can be saved.
