Abstract

PURPOSE:To withdraw a cassette half under a program searched state of a magnetic tape by constituting the subject device in such a manner that the cassette half is ejected under the program searched state by rewinding the magnetic tape at the time of ejecting the cassette half. CONSTITUTION:When a control part 5 of the magnetic recording and reproducing device is supplied with an eject signal, whether the magnetic tape is program-searched or not is decided based on a detecting signal of a tape sensor 4, and when the tape is program-searched, a mechanism part 6 is controlled in order to eject the cassette half. However, when the magnetic tape is not program-searched, after performing the program searching by rewinding the magnetic tape, the mechanism part 6 is controlled in order to eject the cassette half. By this method, when the next information recorded on the magnetic tape is reproduced, the information can be reproduced from the beginning without performing the rewinding operation of the magnetic tape.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to recording information, such as music, on a magnetic tape contained in a cassette half loaded in a mechanical part, or recording information such as music on a magnetic tape. The present invention relates to a magnetic recording and reproducing device that reproduces information.

[Conventional technology]

In a conventional magnetic recording and reproducing device, while the magnetic tape of the cassette half loaded in the mechanical section is running and the information recorded on the magnetic tape is being played back, for example, after operating the stop key on the operation section, the cassette is turned off. When the eject key is operated to eject a half, the cassette half is ejected after stopping the running of the magnetic tape.

[Problem to be solved by the invention]

Conventional recording and reproducing devices are configured as described above, so when playing back information recorded on a magnetic tape with an ejected cassette half loaded into the mechanical section, the magnetic tape is not necessarily located at the beginning. For,
The information is played back from where it left off previously.

Therefore, when reproducing information recorded on a magnetic tape from the beginning, there is an inconvenience in that it is necessary to operate the rewind key on the operation section to find the beginning of the magnetic tape.

Furthermore, when the magnetic tape of the cassette half is a digital audio tape, there is an inconvenience that the table of contents information recorded at the beginning of the magnetic tape cannot be read.

The present invention has been made in order to solve the above-mentioned problems, and provides a magnetic recording/reproducing apparatus which can recover cassette halves while the magnetic tape is at the beginning.

[Means to solve the problem]

The magnetic recording and reproducing apparatus according to the present invention includes a tape sensor that detects the state of a magnetic tape stored in a cassette half loaded in a mechanical section, and an eject signal that ejects the cassette half loaded in the mechanical section. When the magnetic tape is located, it is determined whether the magnetic tape is located based on the detection signal of the tape sensor, and if the magnetic tape is not located, the magnetic tape is rewound and the beginning is located, and then the cassette half is inserted. A control unit is provided to control the mechanical unit to eject.

[For production]

Control i3 of the magnetic recording and reproducing device in this invention [1 part is:
When an eject signal is supplied, it determines whether the magnetic tape is at the beginning based on the detection signal of the tape sensor, and if the magnetic tape is at the beginning, it controls the mechanical part to eject the cassette half. .

However, it determines whether the magnetic tape is cued based on the detection signal of the tape sensor, and if the magnetic tape is not cued, the magnetic tape is rewound and cued, and then the cassette half is ejected. The mechanical part is controlled to do the following.

C Example 3 Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 6 indicates a mechanical section including a cassette loading mechanism, a tape threading mechanism, a recording and reproducing mechanism, and the like.

FIG. 2 is a flowchart for explaining the operation,
STI to ST8 indicate each step.

Next, the operation will be explained.

First, the control unit 5 determines based on the output of the magazine sensor 2 whether a magazine containing a plurality of cassette halves is attached.

Then, with the magazine installed, operate the various keys on the operation unit 1 to specify the cassette half and also specify reproduction of the information recorded on the magnetic tape, and the flowchart shown in Figure 2 starts. Therefore, first, the mechanical unit 6 is controlled to load the designated cassette half to the recording/reproducing mechanism using the cassette loading mechanism and wait for loading (step ST l ).

Note that whether or not the cassette half is loaded into the mechanical section 6 can be determined based on the loading detection signal of the cassette sensor 3.

Then, when the cassette half is loaded, the mechanical section 6 is set to the playback mode and the information is played back (step 5T2).
, it is determined whether the magnetic tape is at the tape end based on the detection signal of the tape sensor 4 (step 5T3).
.

Note that whether the magnetic tape is at the tape top or tape end is determined by the
For example, by determining the detection signal obtained by optically detecting a transparent or translucent leader tape with the tape sensor 4,
You can check the condition of the magnetic tape.

Next, if it is determined in step ST3 that the magnetic tape is not at the tape end, it is determined in step 5T whether or not an eject signal for ejecting the cassette half has been supplied.
4) If no eject signal is supplied, step S
Return to T2.

Note that the eject signal is supplied to the control section 5 by operating the eject key after operating the stop key of the operating section 1, or by directly operating the eject key.

Then, in step 5T5), if the magnetic tape is at the end of the tape as determined in step ST3, or if an eject signal is supplied as determined in step ST4, the mechanical section 6 is set to rewind mode and the magnetic tape is rewound. Based on the detection signal of the sensor 4, it is determined whether the magnetic tape is at the tape top (step 5T6).

Next, if it is determined in step ST6 that the magnetic tape is not the tape top, the process returns to step ST5, and if the magnetic tape is the tape top, the mechanical section 6 is controlled to eject the cassette half (step 5T7). Next, it is determined whether the specified cassette half exists (step 5).
T8).

If there is a next designated cassette half as determined in step ST8, the process returns to step STI to load the next designated cassette half into the mechanical section, and if the next designated cassette half is dropped, End control.

Therefore, the cassette half can be retrieved with the magnetic tape at the beginning, so the next time you want to play back the information recorded on the magnetic tape, you can play the information from the beginning without having to rewind the magnetic tape. can do.

Further, if the magnetic tape of the cassette half is a digital audio tape, the next time the information recorded on the magnetic tape is played back, the table of contents information recorded at the beginning of the magnetic tape can be read.

In the above-mentioned embodiment, an example using a magazine has been described, but instead of the magazine, a cassette storage part that can similarly store a plurality of cassette halves may be built in.

It can also be applied to loading cassette halves one roll at a time without using a magazine or the like.

[Effects of the Invention] As described above, according to the present invention, when ejecting a cassette half, the cassette half is ejected after rewinding the magnetic tape and locating the beginning. This has the effect of allowing the cassette half to be recovered in the current state.

Therefore, the next time you want to play back the information recorded on the magnetic tape, you will not have to rewind the magnetic tape.
Information can be played from the beginning.

If the magnetic tape in the cassette half is a digital audio tape, the next time you play back the information recorded on the magnetic tape, you will be able to read the table of contents information recorded at the beginning of the magnetic tape. There is.
