Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides inter-song detection that enables the beginning of a song by detecting a no-signal portion between songs or detecting a pilot signal recorded at the beginning of a song. This invention relates to a tape recorder with functions.

Conventional technology switches the deck section to stop (or pause) mode when it detects a no-signal section between songs, or when it detects a pre-recorded pilot signal at the beginning of a song, and immediately switches to playback mode. There are two types of switches, which are very convenient for locating the beginning of a desired song.

However, the former type of tape recorder, which has an inter-track detection function that switches from song selection mode to stop mode, has operational problems in that if you want to immediately play a desired song, you have to press the playback switch immediately after detecting a no-signal section. It was an inconvenience.

In addition, tape recorders that have a track interval detection function that automatically switches from the track selection mode to the playback mode do not have the same problem as the former, but they do not have the same problem as the former, but they do not have the same problem as the former, but when the playback signal of the cassette tape on one deck is When used on the playback deck of a tape recorder that performs dubbing to record onto a cassette tape on the other deck,
If the playback mode was automatically switched immediately after the song interval was detected, the deck section on the Suzune side would not be ready, which would be inconvenient.

Problems to be Solved by the Invention Therefore, it is possible to consider a tape recorder that has both track interval detection functions, but in this case, it would be necessary to select between the two track interval detection functions, which would make the operation cumbersome. ,
Operability may deteriorate. In addition, there arises a problem that the number of operable switches increases and the arrangement on the operation panel must be considered, so that it cannot be said to be sufficient for practical use.

The present invention solves the above-mentioned conventional problems, and has two song interval detection functions: one that switches to a pause mode or stop mode when detecting a song interval, and one that switches to a playback mode, and does not impair operability. To provide a tape recorder in which two inter-track detection functions can be selected.

Means for Solving the Problems In order to solve the above-mentioned problems, the tape recorder of the present invention has the following features:
Whether the switch that started the song selection operation is a play switch or a pause switch is stored in a storage means, and when a song interval is detected by the song interval detection means, if the stored content of the storage means is a pause switch, the deck section is To switch from fast forward playback (or rewind playback) mode to pause mode or stop mode, and if the memory content is a play switch, fast forward playback (or rewind playback) of the deck section.
The present invention includes selection means for selecting an operation mode after detecting the song interval so as to switch from the mode to the playback mode.

Function: With the above-described configuration, the present invention stores the switch that started the song selection operation, and depending on the stored content, when detecting a song interval, there are two types of interval detection: one to switch to pause mode or stop mode, and one to switch to playback mode. Since the functions are automatically selected, it is possible to select between two song interval detection functions without sacrificing operability.

Embodiment Hereinafter, a tape recorder according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of essential parts showing an embodiment of the tape recorder of the present invention. In Fig. 1, 1 is a deck section that has at least a song selection mode, and option 2 is a pilot that detects a no-signal section between songs on the tape loaded on the deck section 1 in a song selection mode, or a pilot recorded at the beginning of a song. 3 is a music selection mode setting switch for setting the deck section 1 to a music selection mode; 4 is a music selection mode setting switch for setting the music selection mode by the music selection mode setting switch 3; If it is, the song selection operation will start, and in other modes it will be the playback mode.
1 is an operation switch unit including a pause switch 42 that starts the song selection operation when the song selection mode is set and becomes a pause mode in other modes, and 6 stores the switch that starts the song selection operation. It is a means of memory, and 6
When the song interval detection means 2 detects a song interval, if the memory contents of the memory means 5 are the play switch 41, the deck section 1 is switched from the song selection mode to the playback mode. is a pause switch 42, which selects the operating state of the deck section 1 after detecting a song interval, which selects the deck section 1 to switch from the song selection mode to the pause mode or stop mode; ,
This is a deck control section that performs control including a song selection mode using pause, fast forward playback, or rewind playback.

In this implementation, the deck control unit 7. The storage means 5° selection means 6 are realized by a microcomputer 8.

The operation of this embodiment will be described below based on a flowchart showing a part of the processing operation of the microcomputer 8 shown in FIG. 10 (■) and 20 (2) are connectors, which are connected in the middle of the entire flowchart (not shown) by the microcomputer 8. First, in judgment step 11, the state of the music selection mode setting switch 3 is judged. If the music selection mode is set, the process proceeds to judgment step 12. When the play switch 41 is pressed in judgment step 12, the process proceeds to processing step 13, and the micro combiator is activated. 11'' is stored in the storage means 6 which is a part of the memory section of 8, and when the pause switch 42 is pressed, processing step 1 is started.
The process proceeds to step 4, where "o"' is stored in the storage means 5, and the process proceeds to output step 15.

In the output step 15, the deck control section 7 consisting of a logic operation unit section and a memory section of the microcomputer 8
In this case, the deck section 1 enters the music selection mode of fast forward playback or rewind playback: it outputs the control signal and the process proceeds to judgment step 16. In this state, if the song interval detection means 2 detects the pilot signal stored at the no-signal part or the beginning of the song between songs and determines that it is between songs, the process proceeds to judgment step 17, and the memory content of the storage means 5 is 1''. If so, the deck section 1 in the song selection mode is set to the playback mode in the output step 18, and if the memory content of the storage means 5 is 0'', the deck section 1 in the song selection mode is temporarily stopped in the output step 19. The deck control section 7 outputs a control signal to set the mode or stop mode to the connector 2o.

As described above, according to this embodiment, the storage means 5 stores in the memory of the storage means 5 the switch of the operation switch unit 4 that started the music selection operation, and when detecting a song interval, the stored contents of the memory are changed to the play switch 41. If so, select to switch the operating state after detecting the song interval to playback mode, and if the stored content of the memory is the pause switch 42, select to switch the operating state after detecting the song interval to pause mode or stop mode. Since the switching is made, even if the tape recorder has two inter-track detection functions, the switching can be done automatically without having to select the function, and the operability will not deteriorate.

In addition, since one tape recorder has two song interval detection functions, when you want to hear the playback sound immediately after detecting a song interval, as in normal playback, you can automatically play it back. Furthermore, even if it is adopted as a mechanism on the playback side of a dubbing function such as a double cassent, it can be stopped after detecting an interval between songs, so that a bell sound can be prepared, making it very effective as a function for detecting an interval between songs.

Further, since there is no particular increase in the number of operation buttons, it is unnecessary to consider the arrangement on the operation panel.

Effects of the Invention As described above, the present invention has a deck section having a music selection mode for finding the beginning of a loaded tape, a music selection mode setting switch for setting the deck section in the music selection mode, and a music selection mode setting switch. If the song selection mode is set, the play switch starts the song selection operation, and in other modes it becomes the playback mode, and if the song selection mode is set, it starts the song selection operation, and in other modes, the play switch When a song interval is detected by a pause switch that becomes a stop mode, a storage means for a switch that starts song selection, and a song interval detection means, and the content of the storage means is a play switch, the deck section is changed from a song selection mode to a playback mode. By providing means for selecting an operating state after detecting a song interval, which selects the deck section to switch from song selection mode to pause mode or stop mode if the memory content is a pause switch. υOperating status after song interval detection Two types of song interval detection functions are possible, one that switches to full playback mode and one that switches to pause or stop mode, and the two types of song interval detection function can be automatically selected. This has the excellent effect of greatly improving operability without requiring special selection buttons or complicating the arrangement of the operation panel.
