Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cassette deck provided with two system deck sections so that dubbing is possible.

(Prior Art) In recent years, various so-called double decks have been provided which have two built-in deck sections and which can more easily perform a dubbing operation from one deck section to the other deck section, There are also proposals that allow special reproduction such as automatic music selection and head scanning.

However, in this type of double deck, two function keys are provided independently of each other, and a mode switching key for performing the special playback described above is also provided. Since they must be operated in association with each other, the operation is very troublesome, and there is a drawback that an erroneous operation or the like is likely to occur. For example, in the case of the conventional one, it is necessary to press an independent erasing key when erasing the reproduction tune order stored in advance, and there is a problem that if the user forgets to press this, a malfunction occurs. Also, when performing auto-rec mute (automatic signalless recording), you must operate the auto-rec mute key, which is provided independently at the same time as the operation of other keys, so that the blank between songs can be properly adjusted. Complicated operation was required to set.

(Purpose of Invention) The present invention has been made in view of the above-mentioned points. The purpose of the invention is to facilitate setting operations such as random reproduction and random dubbing, and whether the music selection modes are being executed. Depending on whether or not the function key mode can be used in a multi-functional manner, it facilitates the operation, and when the memory for selecting songs becomes unnecessary, the memory contents can be automatically deleted. The purpose is to provide a cassette deck.

(Structure of the device) In the cassette deck according to the present invention, the program registration is performed by the program registration music key of the reproduction side deck in the memory for storing the selected music, and the program registration order is selected by the reproduction key provided on the reproduction side deck. In a two-system cassette deck having a first operation mode for reproducing and a second operation mode for recording the music reproduced in the program registration order by the recording side deck, the first operation mode, Mode execution detection means for detecting which operation mode is being executed among the second operation modes or which operation mode is not being executed;
Function discriminating means for discriminating which function key is pressed among the keys on the reproduction side deck,
The program is registered, and the first operation mode and the second operation mode are not executed in response to the signals from the mode execution detecting means and the function determining means, and the reproducing side Random reproduction starting means for starting execution of the first operation mode on condition that the reproduction key of the deck keys is pressed,
The program is registered, and the first operation mode and the second operation mode are not executed in response to the signals from the mode execution detecting means and the function determining means, and the reproducing side A signal from the random dubbing starting means for starting execution of the second operation mode on condition that the random dubbing key of the keys of the deck is pressed, and the signal from the mode execution detecting means and the function discriminating means is received. Then, the program in the memory is registered on condition that the first operation mode and the second operation mode are not executed and the key of the reproduction side deck is set to fast forward, fast rewind or stop state. And memory erasing means for erasing the selected song information.

(Embodiment) An embodiment of the cassette deck according to the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a rewritable deck, which is shown as a reproducing deck in the illustrated example, and 2 is also a rewritable deck, which is shown as a recording deck in the illustrated example. . Reference numeral 3 is a memory (random access memory) for storing the selected music piece from the reproduction side deck 1 through the microcomputer. Reference numeral 4 is a key for giving various mode commands to the reproduction side deck 1, which is a reproduction key 4a, a random dubbing key 4b, an index scan key 4c,
And other function keys (including a program registration music key and a key for setting a fast-forward, fast-rewind or stop state, which are not shown).

These two-system cassette decks have a program registration song key provided on the reproduction side deck 1, and a desired song selection program is registered in the memory 3 through a microcomputer, and a reproduction key provided on the reproduction side deck. Playback in the order of program registration selected by
Operation mode (hereinafter referred to as random playback mode)
A second operation mode (hereinafter referred to as a random dubbing mode) for recording the music being reproduced in the program registration order by the recording side deck 2 and a third operation mode for reproducing only the music head in the program registration order. (Hereinafter referred to as a random index scan mode) and the like.

Reference numeral 5 denotes a mode execution detecting means for detecting which operation mode among the random reproduction mode, the random dubbing mode, the random index scan mode, etc. is being executed or which operation mode is not being executed. belongs to. A function discriminating means 6 is for discriminating which one of the keys 4 of the reproducing side deck 1 has been pressed.

Numeral 7 is a random dubbing starting means, which receives the signals from the mode execution detecting means 5 and the function discriminating means 6 so that the random reproduction mode, the random dubbing mode and the random index scan mode are not executed, and Execution of the random dubbing mode is started on condition that the random dubbing key 4b of the keys 4 of the reproduction side deck 1 is pressed.

8 is a random index scan starting means,
The mode execution detection means 5 and the function discrimination means 6
In response to the signals from and, the random playback mode, the random dubbing mode, and the random index scan mode are not executed, and the index scan key 4c of the keys 4 of the playback side deck 1 is pressed. As a result, the execution of the random index scan mode is started.

Reference numeral 9 denotes a memory erasing means, which receives signals from the mode execution detecting means 5 and the function discriminating means 6 so that the random reproduction mode, the random dubbing mode, and the random index scan mode are not executed, and the reproduction is performed. The music selection information in the memory 3 is erased on condition that the key 4 of the side deck 1 is set to fast-forward, fast-rewind or stopped.

An example of the operation of the above configuration will be described with reference to the flowchart shown in FIG. The flow chart shown in FIG. 2 is an example in which the present invention is applied to another control system, and other functions are added, which will also be described.

First, in step 10, it is determined whether or not random reproduction is being performed, and the branch Y (affirmative) proceeds to step 11 and
The branch N (negative) moves to step 12. In step 11, it is judged whether or not the key 4 of the reproduction side deck 1 is pressed, and the branch Y sets the mode of the reproduction side deck 1 (step 13) and erases the program registered music (step 1).
Four).

On the other hand, in step 12, it is determined whether or not the random dubbing is being performed, and the branch Y moves to step 15 and the branch N moves to step 25. In step 15, it is determined whether or not the key 4 is pressed, and the branch Y is set in step 16
The branch N enters a routine similar to that of the branch N in step 11 and moves to the waiting step W. In step 16, it is judged whether or not the recording side deck 2 is recording, and the branch Y moves to step 17 where the recording side deck 2 is set to the auto-rec mute state. When step 17 is executed, the process moves to step 13 described above.

In step 25, it is judged whether or not the program is registered in the memory 3, and the branch Y goes to step 18 and the branch N.
Moves to the waiting step W. In step 18, it is judged whether or not the reproduction key of the keys 4 is pressed, the branch Y is moved to step 19, and in step 19, random reproduction of the reproduction side deck is executed. After performing the random reproduction, the process moves to the waiting step W. The branch N of step 18 moves to step 20, and in step 20, it is judged whether or not the dubbing key has been pressed. The branch Y moves to the waiting step W through execution of random dubbing (step 21). To do.
The branch N of step 20 moves to step 22 and step 22
At, it is determined whether or not the index scan key is pressed. The branch Y of step 22 moves to the waiting step W after the random index scan (step 23) of the reproduction side deck 1 is executed. On the other hand, the branch N moves to step 24 to determine whether the key 4 of the reproduction side deck 1 is set to fast-forward, fast-rewind, or stopped, and the branch Y of step 24 moves to step 13 described above. Then, the branch N moves to the waiting step W.

Next, to explain a concrete operation example, if any of the keys 4 of the reproduction side deck 1 is pressed during the operation of the random reproduction mode, the mode of the reproduction side deck 1 is canceled and the random reproduction mode is released. Then, at the same time as setting to the designated mode, the program registered music is erased. For example, when the reproduction side deck 1 is set to the fast-forward state, the program registered music is erased, and unnecessary music selection information does not remain in the memory 3.

Further, although the program is registered but the random selection is not in progress, when the reproduction key on the reproduction side deck 1 side is pressed, the reproduction side deck 1 starts the random selection of music. As for the order of random song selection, first, when the program registration song key is pressed, the playback side deck 1 is rewound fast, and when the playback key of the playback side deck 1 is pressed in this state, the song is returned to the beginning of the tape. When the operation is started and completely rewound, the music selection is started from the tape position.

Next, if the program is registered but the random dubbing key 4b is pressed while the random playback mode is not in operation, the random dubbing mode is set, and the recording side deck 2 enters the recording pause state and the playback side deck. 1
Starts a random reproduction operation, and the reproduction side deck 1 selects the music according to the program registration order, and then reproduces the selected music, and at the same time, the recording side deck 2 enters the recording state. When the reproduction side deck 1 reproduces the above-mentioned music and the next registered music is selected, the recording side deck 2 stands by in the recording pause. When the double speed dubbing key is pressed, the recording pause, playback and recording are set to double speed (9.5 cm / sec) respectively.

(Effect of the Invention) According to the cassette deck of the present invention, even when performing a random operation such as a random playback mode, a random dubbing mode, a random index scan mode, etc., it is possible to perform any timing without checking the operation mode of the cassette deck. It can be started with.

Also, since the random index scan mode operation can be performed, it is possible to immediately check the arrangement state of the song, and when listening to the next song immediately, skip the song selection easily by pressing the function key of the playback deck. It has an excellent feature that it can be used.
