It is an object of the present invention to provide a tape running time display device which can calculate and display the playing time of a piece of music, for example, by calculating the counted time output.

An embodiment will be described below with reference to the drawings.

FIG. 1 shows a schematic diagram of a system of equipment necessary for operating an embodiment of the tape recorder running time display device according to the present invention. In the same figure, a predetermined portion of information (for example, a music program song) recorded on an open tape of an open reel tape recorder (hereinafter referred to as an open tape recorder) 1 is cut out and the order of the information is arbitrarily changed, and the information is then transferred to a cassette tape recorder 2. When dubbing to a cassette player, a light pen 4 picks up characters, symbols, etc. representing information necessary for dubbing displayed on a monitor television receiver (hereinafter referred to as receiver) 3, and the microcomputer (hereinafter referred to as computer) 5 to obtain a predetermined signal, and the open terminal -
The information recorded on the tape of the precoder 1 is dubbed onto the cassette tape of the cassette tape recorder 2, while the characters etc. picked up by the light pen 4 are printed on printing paper by the controller 6 with a small printer. Also, when the information dubbed on the cassette tape recorder 2 is reproduced in a desired order, the information is picked up by the light pen 4 and the information signal is transmitted through the amplifier T to the speakers 3a and 3b. Take it out. To explain the above system in detail with reference to Fig. 2 and subsequent figures, Fig. 2 shows a specific circuit diagram, and Fig. 6 shows the front panel of the controller shown in Fig. 1. are given the same number. In addition, in FIG. 2, the part surrounded by the dashed line constitutes the main part of the present invention. ? Recording of beginning and end signals In the figure, a four-track open tape recorder 1 has an erasing head, a recording head, and a first recording head on the tape running path.
| A forward playback head (both not shown) that contacts the third channel track and a return playback head (hereinafter referred to as reverse head) 20 that contacts the second and third fourth channel tracks are provided, and the recording head is Songs from a music program such as a broadcast are recorded on, for example, the first and third tracks of an open track by the head.

This tape records not only songs necessary for the editor but also information unnecessary for the editor, such as announcements and commercials. First, switch the mode selector switch 6T provided on the controller 6 to the queue signal recording mode "1", operate the lock type bias switch 14 to close it, connect the analog switch 15 to the terminal R side, and open tape. While the songs recorded on the open tape of the recorder 1 are played back by the forward playback head, the reverse head 20 outputs a beginning signal (hereinafter referred to as the beginning signal) and an end signal (hereinafter referred to as the tail signal) to the beginning and end of each song, respectively. signals) are recorded respectively.

That is, the clock pulse from the oscillator 9 is sent to the waveform shaping circuit 1.
0, the frequency is divided by a frequency divider 11, and further,
The monostable multipipelator 12 generates a pulse waveform with a predetermined duty cycle, and the pulse waveform is supplied to the binary counter 13.

Here, as shown in FIGS. 3A and 3C, the non-lock type cue recording switch 16 is closed approximately 1 second before the beginning of the first song of the open recorder 1 (FIG. 3A) (FIG. 3C). As a result, a differentiated pulse is taken out from the differentiating circuit 22a, a signal Q is taken out from the Q terminal of the flip-flop IT (7), and is supplied to the binary counter 13, which counts, for example, three pulse signals from the frequency divider 11. As a result, the gate circuit 18 takes out the three pulse signals from the multipipulator 12 as shown in FIG. The reverse head 20 records the head signal CS on the fourth track (return track) of the slave group.
When the bias switch 14 is closed, an H level voltage is applied to the transistor Tr during the H level period as shown in FIG. Since the normally closed switch 16a is opened, the diode 21 is turned off only during the recording period of the head and tail signals, and by turning off the diode 21, it can be confirmed that the head and tail signals have been recorded. The bias switch 14 is closed only when recording the head and tail signals, and is normally left open, with the analog switch 15 connected to the terminal P side. Further, as shown in FIGS. 3A and 3C, the cue recording switch 16 is closed again about one second after the end of the first song.

As a result, the signal Q is taken out from the Q terminal of the flip-flop IT (7) and supplied to the binary counter 13.
The gate circuit 18 is opened for a period in which the counter 13 counts, for example, two pulse signals from the frequency divider 11, and two pulse signals as shown in FIG. It is recorded at the end of the first song. Thereafter, in the same manner, three pulse signals (head signal CS) and two pulse signals (tail signal CE) are recorded at the beginning and end of the second and subsequent songs, respectively. . At this time, due to the operation of the flip-flop IT, a head signal is recorded when the cue recording switch 16 is closed for an odd number of times, and a tail signal is recorded for an even number of times the cue recording switch 16 is closed. Reference numerals 23a and 23b are cancel switches which, when closed, restore the state of the output signal of the flip-flop IT to the state before operating the switch 16 when the cue recording switch 16 is operated by mistake, and also restore the state of the output signal of the flip-flop IT to the state before operating the switch 16.
is grounded to prevent gate output from occurring.

The open child precoder 1 searches for a song in the play mode and enters the playback state.

0K monitor Next, a display called 0K monitor will be explained.

From the force set tape recorder 2, the on/off status of the power set of the force set tape recorder 2, whether or not the force set half is attached,
Information signals corresponding to whether the recording is possible or not are supplied to the 0K monitor storage section 52, and the open tape recorder 1 also outputs information such as turning on/off the power of the open tape recorder 1, setting the secondary arm or not, and switching the source/tape. Information signals corresponding to the connection states to the terminals of the switch, etc. are supplied to the 0K monitor storage section 52 and stored therein, and are further supplied to the video RAM 28 to send these 0K signals to the receiver 3.
Display K monitor items. In this case, for example, when turning on/off the power of the open tape recorder 1, [0PEN
REELP0WER0N" is displayed. For example, if you want to check this item, use the light pen 4 to pick up this item.

At this time, if the power is turned on normally, "0K" is displayed after this item, and if the power is turned off, "??" is displayed after this display.
The "???" display for the above items is configured to automatically switch to "0K" in response to individual operations such as turning on the power or attaching the force set half. . In addition, a color composition circuit (or blinking circuit) 64 is connected to the 0K monitor storage unit 52 so that a predetermined color is displayed only on the line of the item where the above-mentioned "??" is displayed, or the item is displayed blinking. You can also do this. This results in
The operator can easily check the status of the open tape recorder 1 and the force set tape recorder 2, and can check the status of these secondary recorders before dubbing. In addition, the modes of the open tape recorder 1 and the power setter recorder 2 are detected by the operating state detection circuits 59 and 60, respectively, and are supplied to the video RAM 28 to be displayed on the receiver 3, such as "PLAY", " You can easily check the mode of the tape recorder by displaying the characters ``REC''.
Accidents such as erroneously shifting to another mode can be prevented.

Reproduction of a power setter recorder Next, a case will be described in which the songs copied onto the tape of the power setter recorder 2 are played back in order or with the order changed.

When the switch 67 provided on the controller 6 is rotated to the force set monitor mode "3" and the cassette monitor switch 66 is closed, a signal is taken out from the drive circuit 44 and the force set tape recorder 2 enters the playback state. The tape is run. As a result, the information signal of the song title recorded as an FM signal at the beginning of the tape is extracted in the order of the songs selected and recorded first, demodulated by the FM demodulation circuit 53, and then sent to the serial/parallel conversion circuit 54. After being converted into a parallel signal, it is supplied to the video RAM 28 via the character generator 42, and the song title is displayed on the receiver 3 again. At this time, since the end signal is recorded on the force set tape at the end of the song title information, this end signal is detected by the end signal detection circuit 62 and becomes a stop signal by the drive circuit 44, thereby causing the force setting to start. The tape recorder 2 temporarily enters stop mode. here,
When the light pen 4 picks up the desired playback songs according to the desired playback order, this signal is sent to the command decoder 3.
3 is supplied to the force set reproduction order storage section 55 and stored therein, and is further supplied to the determination (comparison) circuit 5T and the drive circuit 44.
This causes the force set tape recorder 2 to go into fast forward or rewind mode.

On the other hand, a song interval detection circuit 56 detects the number of unrecorded portions on the set tape, and a song interval counter 63 counts the number of unrecorded portions. The song interval counter 63 is set to count by 1 when the power set tape recorder 2 plays back a song title and enters the stop mode, and a signal corresponding to the number of unrecorded portions is supplied to the comparison circuit 5T.
The determination (comparison) circuit 5T compares this signal with a predetermined signal corresponding to the song number stored in the force set playback order storage section 55, and the signal from the storage section 55 and the signal from the counter 63 match. A detection signal is taken out, and this signal is supplied to the drive circuit 44, whereby the power set tape recorder 2 is put into the play state from the fast forward or rewind mode, and the desired song is reproduced. When a desired song is picked up with the light pen 4, for example, "N2,n" is displayed on the first line of the screen of the receiver 3, as shown in FIG.
5, n,...'' will be displayed, so
It is possible to determine which song to play. When the playback of the song is finished, a detection signal obtained by counting the number of continuous unrecorded portions is supplied to the judgment (comparison) circuit 5T, where it is compared with the signal from the storage section 55 and the tape is moved to a predetermined position. Then, in the same way as in the above case, a search operation for a song stored in the force set playback order storage section 55 is entered, and the desired song is played back.

At this time, the inter-song counter 63 also operates during fast forwarding or rewinding, but the force set playback order storage section 55 receives a signal instructing the reading of the next track number only when an inter-song interval is detected during play. It is configured to emit. This is done by configuring the time constant in the inter-track detection circuit 56 to be different during fast forwarding or rewinding and during play, and supplies only the detection output obtained during play to the power set playback order storage section 55. You can configure it like this. In this way, by picking up the songs displayed on the receiver 3 with the light pen 4, desired songs can be reproduced from the dubbing tape in a desired order. During this playback operation, the signal of the track number being played is taken out from the power set playback order storage section 55 and supplied to the color synthesis circuit (or blinking circuit) 58 to obtain a predetermined signal. The number of the song being played, the name of the song, and the required playing time are displayed on the screen, and the line is displayed in a predetermined color, or the text is displayed in color, or the text is made to blink. You can easily confirm which one it is.

As described above, the tape running time display device for the Kanichi precoder according to the present invention includes a counting means for converting and counting the running distance of the tape into time, and a beginning signal and a starting signal at the beginning and end of the information recorded on the tape, respectively. a recording means for recording the last signal; a storage means for storing the counting time from the counting means when a recording operation is performed; The structure is composed of a calculation means for calculating the running time of the tape up to the end point, and a display means for displaying the tape running time calculated by the calculation means, so that the beginning and end of the song recorded on the tape can be displayed. It is possible to calculate the playback time of only the information part between When editing and recording on tape, it has the advantage that songs can be easily combined depending on the length of the tape.
