Abstract

PURPOSE:To enlarge an operation button and to increase the operability by detecting the pressing state of an operation button, measuring the length of pressing time and number of pressing times and deciding either a fast forwarding mode or music selective mode, or how many are the number of musics. CONSTITUTION:A fast forwarding button 9 has the function capable of performing the setting of either a fast forwarding mode, music selection mode or the number of music selections by a control circuit 7 and these functions are discriminated by the pressing method of the fast forwarding button 9. For instance, the control circuit 7 decides that a fast forwarding mode is instructed when the button 9 is continuously pushed more >=3sec and in the case of the time of the button 9 pushed continuously being for <3sec the control circuit 9 decides the music selection mode being instructed. At the time when the pressing of the button 9 for <3sec is performed in plural times, the control circuit 7 decides that the performance of the music selection by the number of pressing times thereof is instructed. Since plural functions may be owned on one operation button accordingly, the function can be increased without increasing the number of operation buttons, the operation is facilitated and a malfunction can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control device for a cassette tape recorder.

C. Prior Art] Conventionally, a cassette tape recorder having a music selection function is known, as disclosed in, for example, Japanese Utility Model Publication No. 59-28521. This song selection function is a cueing function that causes the tape to run at high speed when a song selection operation is performed, and when a no-signal portion between songs is detected, starts playing from there. This song selection function is suitable when you want to skip songs you don't want to listen to or quickly find songs you want to listen to.
It is executed with the simple operation of simply pressing the song selection button,
This is an effective function for car-mounted cassette tape recorders.

[-Problems that A Ming tries to solve]

By the way, in the conventional music selection function, as described in the above-mentioned known literature, only one music can be selected in one music selection operation. When the selected music piece has been reproduced, the music selection operation must be performed again, which is extremely troublesome.

Therefore, it is desirable to have a function that allows selection of a plurality of songs at once, but for this purpose, it is necessary to provide a separate operation button for this purpose.

On the other hand, the operation section of a cassette tape recorder has various operation buttons in a narrow area, and it is difficult to add more operation buttons to this, so the order of operation must be reduced. (In particular, military cassette tape recorders have a very narrow operation section, and if the number of operation buttons is increased and the order of operation is reduced, it is difficult for the driver to operate the cassette tape recorder while driving.) becomes extremely difficult.

SUMMARY OF THE INVENTION An object of the present invention is to provide a control device for a cassette tape recorder that solves these problems and allows for large operation buttons to achieve high operability.

[+ steps to solve problems]

In order to achieve the above object, the present invention detects the suppression status of an operation button, measures the length of time it is pressed and the number of times it is suppressed, and determines whether it is in fast forward mode or song selection mode, and if it is in song selection mode. For example, the number of songs to be selected is determined, and an operation is performed based on this determination.

[Effect]

A single operation button has three functions: fast-forward mode setting, song selection mode setting, and number of songs selection settings, making it possible to increase the functions of the cassette tape recorder while preventing an increase in the number of operation buttons on the operation panel. .

Since the number of operation buttons is not increased, each operation button can be made larger, and only the desired operation button can be suppressed more easily, improving operability.

〔Example〕

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

The figure is a configuration diagram showing an embodiment of a control device for a cassette tape recorder according to the present invention, in which t2 is a reel, 3 is a tape, 4 is a head, 5 is an amplifier, ie a detection circuit, 7 is a control circuit, and 8 is a play button, and 9 is a fast forward button.

In the figure, the control circuit 7 feeds the tape 3 at normal speed or high speed or stops the tape 3 by operating the playback button 8, the fast forward release 9, the detection output of the detection circuit 6, etc.

The head 4 is in contact with the tape 3 and is in a position to reproduce the signal, regardless of whether the tape 3 is normally fed at high speed. The playback signal from the head 4 is amplified by an amplifier 5 and then supplied as an audio output to a playback processing circuit (not shown), and also to a detection circuit 6 for detecting no-signal portions between songs on the tape 3. Ru.

The fast-forward button 9 has a function that allows the control circuit 7 to set a fast-forward mode, a song selection mode, and the number of songs to be selected (note that even in the song selection mode, the tape 3
is fast-forwarded, but in this case, a mode in which the tape 3 is fast-forwarded and no music is selected is called a fast-forward mode, and a mode in which music is selected is called a music selection mode. ), these functions can be accessed using the fast forward button 9.
It is determined by the method of suppression. For example, if the fast forward fin 9 is pressed for more than 5 seconds, the control circuit 7
The control circuit 7 determines that the fast forward mode has been instructed, and when the fast forward button 9 is kept pressed for less than 3 seconds, the control circuit 7 determines that the music selection mode has been instructed.

Further, when the fast-forwarding switch 9 is pressed a plurality of times for less than 3 seconds, the control circuit 7 determines that an instruction has been given to select music for the number of times the fast-forwarding switch 9 is pressed.

The detection circuit 6 is controlled to be switched between an activated state and a non-activated state by a control circuit 7. When the control circuit 7 determines that the music selection mode is designated by the operation of the fast forward button 9, the detection circuit 6 is activated, and when the fast forward mode is instructed by the operation of the playback button 8 or the fast forward a9, the detection circuit 6 is activated. do not.

When the detection circuit 6 detects the no-signal portion of the reproduced signal from the amplifier 5, -.

A signal is sent to the control circuit 7 at the detection timing.

As a result, the control circuit 7 switches the running speed of the tape 3 from the high speed to the normal speed K, sets the playback mode, and starts playing the song.

When the fast forward button 9 is pressed multiple times to specify multiple selections, the control circuit 7 stores the number of times of selection, performs the selection operation as described above, and starts playing the first song. From then on, the control circuit maintains the playback mode until the specified number of songs have been played. During this time, the detection circuit 6 is kept in the operating state, and the control circuit 7
send a signal to. Each time the control circuit 7 receives this number 1, it counts the number of reproduced songs, re-indicates the reproduction mode, and stops the tape 3 when the specified number of songs have been reproduced.

In this way, the fast forward mode, music selection mode, and number of music selections can be specified using one fast forward button.

In the above explanation, the tape 3 is fast-forwarded when selecting music, but it may be rewound.

〔Effect of the invention〕

As explained above, according to the present invention, one operation button can have multiple m+i, so functions can be increased without increasing the number of operation buttons.
Functions that were previously performed using separate operation buttons can now be performed with a single operation button, reducing the number of operation buttons and avoiding downsizing or increasing the size of operation buttons. This provides excellent effects such as ease of operation and prevention of erroneous operations.
