Abstract

PURPOSE:To select two intermusic detecting functions without losing the operability by storing whether the mechanism section before intermusic detection is in the reproducing state or in the stop state to a storage means and selecting automatically the operating state after the detection of intermusic. CONSTITUTION:An inter-music detecting means 5 detects an inter-block between pieces of music on a cassette tape on which plural pieces of music are recorded. The storage means 6 before the inter-music is detected stores whether the mechanism section 1 is in the reproducing state or the stop state before the inter-music detecting state is obtained. When the storage means 6 is in the reproducing state, the mechanism section 1 changes over the state from the fast feeding reproduction (or rewinding reproduction) into the reproducing state and when the content of the storage means 6 is in the stop state, the mechanism section 1 changes over the mode from the fast feeding reproduction (or rewinding reproduction) into the stop state so as to output a command to the mechanism control section 2.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF THE INVENTION The present invention relates to a tape recorder having an inter-music detection function that detects the no-signal portion between songs and allows the beginning of the song to be found.

Conventional structure and its problems In general, the inter-track detection function of a tape recorder stops the mechanism (
There are two types: one that switches to the playback state (or pause) and one that immediately switches to the playback state, which are very convenient for locating the beginning of a desired song.

However, with the former type of tape recorder, which has an inter-track detection function that switches from an operating state to a stopped state, if you want to immediately play a desired song, you have to press the play button immediately after detecting a no-signal section. There was an inconvenience.

In addition, tape recorders with the latter inter-track detection function that automatically switches from the inter-track detection operating state to the playback state do not suffer from the former problem, but cassettes with one mechanism, such as double-cassent tape recorders, When used in the playback mechanism of a tape recorder that performs dubbing by recording the tape playback signal onto a cassette tape in the other mechanism, if the playback mechanism automatically switches to playback immediately after detecting an interval, the recording side This was an inconvenience as the mechanism could not be prepared.

Therefore, a tape V-t-
However, in this case, it would be necessary to select between the two inter-track detection functions, which would make the operation cumbersome and may result in poor operability. In addition, the number of operation buttons increases, and the arrangement on the operation panel must be considered, which is a problem that is not sufficient for practical use.

Purpose of the Invention The present invention solves the above-mentioned conventional problems, and has two inter-music detection functions, one for switching to the operating state after detecting the inter-song interval, and the other for switching to the playback state after detecting the inter-song interval. The present invention provides a tape recorder that allows selection of two inter-track detection functions.

Structure of the Invention The present invention is a tape recorder having two functions, one for switching the mechanism section to a playback state and the other for switching a mechanism section to a stop state after detecting an interval as a song interval detection function of the tape recorder. Whether the mechanism section is in a playback state or a stop state 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 playback state, the mechanism section is stored. Fast forward playback (
After detecting an interval between songs, the mechanism switches from the fast-forward playback (or rewind playback) state to the stop state if the stored content is stopped. This tape recorder is characterized by automatically selecting the state, thereby making it possible to select between two song interval detection functions without impairing operability.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a block diagram of essential parts showing an embodiment of a tape recorder of the present invention.

Reference numeral 1 denotes a mechanism section, which is controlled by a mechanism control section 2 to operate in modes such as recording, playback, fast-forward one rewind, fast-forward playback one rewind, playback, and stop. 31r
Mechanism operating means for inputting operation commands to the i-mechanism control section 2; 41d on/off switch for detecting between songs; 5, a song for detecting a no-signal section between songs on a cassette tape on which a plurality of songs have been recorded; This is an interval detection means.

Reference numeral 6 denotes a storage means for a pre-song-interval detection operation state for storing whether the mechanism section 1 was in a playback state or a stopped state before entering the inter-song-interval detection operation state, and 7 is an inter-song detection means 5
When an interval between songs is detected, if the contents of the storage means 6 are in the playback state, the mechanism section 1 switches from the fast forward playback (or rewind playback) state to the playback state. is in the stopped state, the mechanism section 1 selects and outputs a command to the mechanism control section 2 to switch from the fast forward playback (or rewind playback) state to the stop state. be.

FIG. 2 is a specific circuit diagram of this embodiment, in which the functions of the mechanism control section and the storage means 2 selection means are realized by a microcomputer.

Reference numeral 11 denotes a mechanism section, and 12 a microcomputer that inputs operational commands such as a fast forward button 13, a rewind button 14, a play button 16, a stop button 16, and an on/off switch 17 for detecting between songs. is driven and controlled.

18 is a song interval detection circuit.

The operation of this embodiment will be explained below based on 70-Theyat showing a part of the processing operation of the microcomputer shown in FIG.

First, it is determined in step 21 whether the state before the song interval detection operation is in a playback state or a stop state, and if it is in a playback state, step 2
Proceed to step 2, where n I 11 is stored in the memory of the microcomputer 12 (hereinafter referred to as microcomputer), and if it is in a stopped state, proceed to step 23, where o'' is stored in the memory.
is memorized.

Next, the on/off switch 17 for detecting between songs, and the fast forward button 13
When the rewind button 14 or the like is operated to start a song, the process advances to steps 23 and 24, and the mechanism section 11 enters a song interval detection operation state for fast forward playback or rewind playback. When the song interval detection circuit 18 detects an interval between songs in this state, the process proceeds to steps 25 and 26, and if the stored content of the memory stored in step 22 and 23 is '1'', the process proceeds to step 27 and the mechanism section 11 is The playback state is returned to the same as before the song interval detection operation.If the stored content of the memory is o'', the process proceeds to step 28, and the mechanism section 11 is returned to the same stop state as before the song interval detection operation.

As described above, according to the present embodiment, the mechanism section 11 of the tape recorder stores in the memory whether it is a playback state or a stop state before the inter-track polar ratio operation, and if the content of the memory is in the playback state when detecting a track interval. The operating state after detecting a song interval is switched to the playback state, and if the memory contents are in a stopped state, the operating state after detecting a song interval is switched to a stopped state. Even if a tape recorder has an interval detection function, the function can be automatically switched without any selection operation, and 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. Further, even if it is adopted as a playback mechanism of a dubbing function such as a double cassect, it can be stopped after detecting an interval between songs, so that preparations for recording can be made, so it is 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 According to the tape recorder of the present invention, it is possible to perform two types of inter-song detection functions: one that switches the operating state after detecting an inter-song to the playback state and one that switches the operating state to the stop state. This has the excellent effect that the selection of functions can be performed automatically, and the operability can be greatly improved without requiring a special selection button or complicating the arrangement of the operation panel.
