Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording device (including a magnetic recording / reproducing device having a reproducing function) such as a video tape recorder (VTR), and more particularly, it is attached to a tape cassette for recording. The present invention relates to a magnetic recording device provided with a mechanism for automatically printing characters such as titles on a cassette label.

[0002]

2. Description of the Related Art In a magnetic recording device (hereinafter also referred to as "VTR"), it is common to record a television broadcast program on a tape cassette and enjoy it. Also, during the time of the desired broadcast program, V
When recording operation of TR is not possible, timer recording (absent recording) is performed so that the program in the set time zone is automatically recorded.

In order to organize the recorded tape cassettes recorded in this way, as shown in FIG. 12A, the label 1 attached to the back surface of the tape cassette 1 is used.
Enter the title and recording information (eg SP / EP, NR-ON / OFF) of the recorded broadcast program on the label a or the label 1b attached on the top to distinguish it from other tape cassettes. There is. Further, in recent years, a caption signal in which information such as a title of a broadcast program is inserted in a vertical blanking period of a video signal, or a VPS signal in which information such as a start time of a broadcast program is inserted has been proposed.

[0004]

When recording is performed using the above-mentioned conventional VTR, there are the following inconveniences. The title and recording information of the program recorded on the label of the tape cassette may be entered immediately after recording, but it is troublesome to enter each time. If you try to fill in all together later, you will lose memory as you record the program earlier, and you will have to play it back and check it. When recording, when the stock of virgin (unrecorded) tape is exhausted, it will be recorded in the unrecorded part of the tape cassette (hereinafter also referred to simply as “cassette”) that has been recorded halfway, but what tape is left I don't know immediately if I can record for about a minute.

Therefore, the present invention is to record using the program information inserted in the vertical blanking period of the video signal and to print it on the label of the tape cassette.

[0006]

To solve the above problems, the present invention provides the following configurations.

In FIG. 1, a video signal aa is supplied to one input of the first switch circuit SW1 from a transmission line (not shown). Further, the modulated video signal is supplied from the antenna 109 to the tuner 110, and the demodulated video signal is supplied to the other input of the first switch circuit SW1. And
A selected video signal bb obtained by selecting both signals using a control signal supplied from a manual switch (not shown) in the first switch circuit SW1 is supplied to the decoder 112, the adder circuit 115, and the recording means 107.

The decoder 112 then selects the selected video signal b.
The signal having the program information inserted in b is extracted. This signal is, for example, a so-called caption signal shown in FIG. 2, in which a preamble period T1 for synchronization and a start code period T for specifying the start time of information are specified.
2 and an information period T3 having program information, which will be described later, and is inserted in the 21st line of the video signal.
Then, the program information signal cc obtained by demodulating the above signal is supplied to the timer unit 102 and the second switch circuit SW2. The details of this decoder are described in, for example, Nikkei Electronics No. 537 P.149 to P.158 1991.9.30.

The timer section 102 has a role of performing a timer recording reservation processing function, and specifies a "channel", a "program start time", a "program end time", a "title" and a program separated from the program information signal cc. Program information related to the current program, such as the "program number", is stored in a memory (not shown). In addition, at a predetermined time, a program guide corresponding to a "program number", a "channel", a "program start time", and a "program end time" relating to future programs is separated from the program information signal cc. Stored in memory. on the other hand,
"Channel", "day", "program start time", "program end time" desired by the operator supplied from the timer reservation operation key 103 or the light receiving unit 104 which receives a signal (such as infrared rays) from the remote controller 105. Program information such as "and" program number "is also stored in the memory.

In setting the reserved program, the display signal 101a from the system controller 101 is set to the second switch circuit S.
A well-known graphic generation circuit 114 for converting a digital signal into an analog signal of a predetermined character, symbol or the like via W2.
The output signal is supplied to a television receiver 116 (hereinafter abbreviated as "TV") via an adder circuit 115, and the recording reservation can be set interactively. In order to make the screen easy to see when setting the recording reservation, the addition circuit 1 is provided so that the output signal of the graphics generation circuit 114 and the selected video signal bb are not substantially added.
The system controller 101 controls 15 using a control signal (not shown).

Now, a method for setting a recording reservation will be described with reference to the flow chart shown in FIG. 3 and with reference to FIGS. The recording reservation setting methods are roughly classified into a normal recording reservation and a recording reservation using a program number. In the former, the operator inputs "channel", "day", "program start time" and "program end time", and in the latter, recording reservation can be completed only by inputting a 4-digit program number, for example. It is a thing.

First, when the setting of the recording reservation is started in S100, the normal recording or the program number recording is selected in S10.
Go to 1. At this time, the screen shown in FIG. 4A is displayed on the TV, and it is necessary to select "normal" indicating normal recording or "number" indicating number recording. That is, the operator uses the left and right arrow keys 105a shown in FIG.
Select "Normal" or "Number". Whether or not it is selected can be confirmed by blinking "normal" and "number" respectively, and pressing the left arrow key will select "normal" from "number".
On the other hand, when the right arrow key is pressed, the selection state is switched from "normal" to "number". Then, the execution key 105c is pressed to confirm the current selection state. In this way, the normal recording or the program number recording is selectively selected, and when the normal recording is selected, S is selected.
If the program number recording is selected in 104, the process proceeds to S102.

In S102, which is a step of setting a program number, the screen shown in FIG. 4B is displayed, and the operator inputs a desired program number with a four-digit numeric keypad 105b to correct it. In such a case, the arrow keys 105a are used to replace the respective numbers with newly input numbers for correction, and the execution key 105c is pressed to confirm the current selection state. When S102 ends, S10
Go to 3.

S103 is a step for setting whether to end or continue the recording reservation, and the screen shown in FIG. 4G is displayed. Then, the operator operates the arrow keys 105a.
Similarly to S101, one of “end” and “continue” is selected by using, and the current selection state is confirmed by pressing the execution key 105c. In this way, when "end" is selected, the process proceeds to S109 to end the recording reservation. On the other hand, if "continue" is selected, the process proceeds to S101 to continue recording reservation.

On the other hand, S104 is a step of setting a channel, and the screen shown in FIG. 4C is displayed, and the "channel" from 1 to 12 is selected by using the arrow key 105a. This selection state can be confirmed by blinking numbers, and the current selection state is confirmed by pressing the execution key 105c. Incidentally, the "channel" may be selected using the ten keys 105b, and in such a case, it is displayed in the lower right corner of the screen. Further, the channels are not limited to 1 to 12, and, of course, * 1, * 2, etc. are displayed to support UHF broadcasting, and it is possible to select these. When S104 ends, S1
Go to 05. Further, S105 is a step of setting a recording date, and a screen having a calendar is displayed as shown in FIG. 4D, and the arrow keys 105a are used to display 1 to 31.
Select “Day” up to. This selection state can be confirmed by blinking numbers, and the current selection state is confirmed by pressing the execution key 105c. If the month of the displayed screen is not desired, the desired month can be displayed using the screen key 105d. Also, "day" may be selected using the ten-key pad 105b, and in such a case, it is displayed in the lower right corner of the screen. By this input, the "day of the week" information is also substantially input. Then, when S105 ends, the process proceeds to S106.

Step S106 is a step of setting a recording start time, and a screen having a clock shown in FIG. 4E is displayed, and the recording start time is set by using the arrow key 105a. That is, when the leftward arrow key is pressed, the clock rotates counterclockwise, and when the rightward arrow key is pressed, the clock rotates clockwise, and the time is displayed as "15:00" shown in the figure. Then, the execution key 105c is pressed to confirm the current selection state. The "recording start time" may be selected using the ten keys 105b. And S10
When 6 ends, the process proceeds to S107.

Step S107 is a step of setting a recording end time. A screen having a clock shown in FIG. 4F is displayed, and the recording end time can be set similarly to S106. The displayed recording end time is displayed as it is, and the recording end time is added to the display. Further, the hatched portion in FIG. 7F is the display of the recording time, and is displayed in red, for example. Incidentally, the “recording end time” may be selected using the ten keys 105b. Then, when S107 ends, S10
Go to 8.

Similar to S103, S107 is a step of setting whether to end or continue recording reservation, and FIG.
The screen shown in (G) is displayed. And "end"
If you select, the process proceeds to S109 and the recording reservation ends,
If "continue" is selected, the process proceeds to S101 to continue recording reservation. In this way, the recording reservation can be set.

"Channel""day""starttime""endtime" set by the above-described recording reservation setting method
Are stored in the timer unit 102. And
Signals are exchanged between the timer unit 102 and a system control unit (CPU; hereinafter abbreviated as “syscon”) 101 that controls the overall operation of the VTR 100, and actual recording reservation is performed. That is, the system controller 101 determines whether or not the time indicated by the built-in clock and the time set in the recording reservation match, and when the set time (or a little before the time required to start recording) is reached, The recording means 107 is controlled on the basis of each recording reservation data stored in the memory of the timer section 102, and signal recording of the selected video signal bb to the cassette 1 is started (see JP-A-63-308757).
Incidentally, in the recording reservation using the program number, the program number obtained from the program number is “channel” “day” using the program guide obtained in advance.
Recording content data such as "recording start time" and "recording end time" are set.

The above-mentioned system controller 101 includes the well-known tape remaining amount detecting means 1 as disclosed in, for example, Japanese Patent Application Laid-Open No. 53-6004 and Japanese Utility Model Laid-Open No. 62-101188.
From 06, the remaining amount data of the tape is supplied. Further, label usage detection means 117, which will be described later, supplies label usage data attached to the tape cassette. Then, the system controller 101 prints the contents stored in the memory means on the label portion of the tape cassette (printer means) 108, and the tape cassette mounted at a predetermined location in the VTR 100 receives signals such as video and audio signals. The recording means (recording means) 107 for recording the data and the reproducing means (not shown) are controlled. The memory means for storing the recorded content data is composed of a RAM or the like, and is incorporated in the system controller 101.

Now, the structure and operation of the main part of the magnetic recording apparatus 100 of the present invention will be described with reference to FIGS. 6 and 7. FIG. 6 is a side view showing a main part of the VTR 100 of the present invention, showing a state where the cassette 1 is mounted at a predetermined position. As shown in this figure, VTR1
The printing means (printer mechanism) 18 is disposed between the front panel 6 of 00 and the cassette 1, and is fixed to the mechanical deck 5 via the transfer pressure bonding mechanism 9. As shown in FIG. 7, the transfer pressure bonding mechanism 9 has a function of moving the printing means 18 up and down, and pressing the printing means 18 against the label 1a when printing on the label 1a. In addition, various information signals are transmitted to the printing means 18 from the timer microcomputer 8 (built in the timer unit 102) through the mechacon microcomputer 7 (built in the syscon 101). It is configured. A label use detecting means 117 is provided on the upper surface of the printer unit 2, and an infrared light emitting diode and a light receiving element are used to determine whether or not three identification areas 1aa in FIG. It is discriminated by the structure that has as a main part. Then, the identification signal 117a is sent to the system controller 101.
Next, the detailed structure and operation of the transfer crimping mechanism 9 will be described with reference to FIGS. 8 to 10. 8 to 10, when the drive motor 21 is rotated by supplying a later-described control signal to a motor drive circuit (not shown), this rotational force is transmitted through the belt 22 to rotate the pulley 23, and further, the worm. The control cam 25 is rotated via the worm wheel 24 (not shown). A cam groove (not shown) is formed in the control cam 25, and a pin (not shown) fixed to the arm of the pantograph 26 is configured to slide.

Further, a cam (not shown) is also formed on the outer periphery of the control cam 25, and the press lever 28 via a pin (not shown) performs a horizontal pressure bonding operation in synchronization with the vertical movement of the pantograph 26. The press lever 28 and the printer unit 27 are provided with tension springs 29a, 29.
Since they are elastically connected via b, the same crimping force can always be obtained. Further, a rotary encoder (not shown) is mounted coaxially with the control cam 25, and the mechanical controller controls the vertical movement and the crimping movement of the printer unit 27 by the signal thereof.

Next, the actual printing operation will be described with reference to the flowchart of FIG. First, S20
In 0, an operator turns on an AC power switch (not shown) provided on the front surface of the VTR 100 to supply AC power. When S200 ends, the process proceeds to S201. In S201, the print data supplied to the printer mechanism 18 is set to the initial state. Then, when S201 ends, the process proceeds to S202. In step S202, the printer mechanism 18 is in a state in which the pantograph 26 in the transfer pressure bonding mechanism 9 is folded as shown in FIG.
Then, when S202 ends, the process proceeds to S203. S20
At 3, the tape cassette 1 is inserted through the cassette insertion port 4, and the cassette 1 is mounted at the position shown in FIG. 6 by a transfer mechanism (not shown). When S203 ends, S
Proceed to 204.

In S204, the syscon 101 determines whether or not a recording reservation is made, and if recording is in progress, S206
If not, the process proceeds to S205. In S205, the syscon 101 controls the VTR 100 based on an input command such as reproduction, fast-forward, rewind, etc. obtained by the operator, and a loop is formed by S205 and S204. on the other hand,
In S206, the syscon 101 determines whether or not the recording is completed. If the recording is in progress, the process returns to the input of S206 to continue this determination, and if the recording is completed, the process proceeds to S207. S2
At 07, the system control unit 101 determines whether or not the print selection switch 118 is short-circuited.
If not, the process proceeds to S210.

In step S208, it is determined whether the number of programs to be printed is less than a predetermined value. That is, the area of a label that can be printed is limited, and when printing is performed on a portion without a label, the print head may be damaged. Here, the following description will be continued assuming that the predetermined value is “3”, for example. If the number of programs is 4 or more, the process proceeds to S210, and if the number of programs is 3 or less, the process proceeds to S209. And
In S209, recording reservation data (or its main data),
For example, the day of the recording (start) The day of the recording (start), time (start time), channel, title, and remaining tape time are stored as one unit in the memory means in the system controller 101. When S209 ends, the process proceeds to S210.

In S210, it is determined whether or not the cassette tape 1 is ejected by the operation of the operator, and if it is not ejected, the process proceeds to the input of S204, and the processes from S204 to S210 are repeated. On the other hand, when discharging, the process proceeds to S211.
In step S211, the system controller 10 determines whether the recording reservation data stored in the memory unit of the system controller 101 in step S209 exists.
Judge with 1. If not, the process proceeds to S215, and if there is, the process proceeds to S212.

In step S212, in order to obtain the identification signal 117a, the transfer press-bonding mechanism 9 is moved to the system controller 1 so that the identification area 1aa of the label 1a can be scanned by the label use detecting means 117.
01 controls. When S212 ends, S21
Go to 3. In S213, print data is determined. That is,
The number of programs that can be printed on the label 1a is obtained from the identification signal 117a, and then the recording reservation data (or its main data) stored in the memory means in the system controller 101 is read in S209, and the recording is performed according to the number of printable programs. The reservation data is the print data. Then, when S213 ends, S
Proceed to 214.

In S214, the syscon 101 controls the printer mechanism 18 as described above, and the print data is displayed on the label 1a of the tape cassette 1 as shown in FIG.
Printing is performed as shown in FIG. In this print example, from the left, there are data for recording (start) day of the week, time (start time), channel, remaining tape time, and tape usage, and three programs are printed for each. Besides this, various information can be printed by changing the software (the program written in the ROM of the system controller 101). When S214 ends, the process proceeds to S215.

In step S215, the printer mechanism 18 is prepared for ejecting the tape cassette 1 with the pantograph 26 in the transfer pressure bonding mechanism 9 folded as shown in FIG. When S215 ends, the process proceeds to S216 and the tape cassette 1 is ejected. This completes the printing operation, but the process itself is S203 in preparation for the next insertion of the tape cassette 1.
Proceed to input.

In this way, the label 1a of the tape cassette 1 can be printed as desired. In addition, above,
Which of the lower and middle columns to print? The determination may be realized by arranging the memory (memory means) in the syscon 101 to store the number of times of recording in the cassette 1, or an appropriate switch means is provided on the front panel 6. Alternatively, the input may be manually performed.

As a printer used as the printer mechanism 18, a small type ink roll printer is advantageous in view of the storage space, but if it can be downsized, a thermal transfer printer, wire dot printer, Anything such as an inkjet printer may be used. In the above description, the printer mechanism 18 is vertically moved as shown in FIG.
Although the operation is performed in stages, it is of course possible to use two stages or four or more stages, and characters may be written vertically. Further, by adding a mechanism for sliding the printer mechanism 18 in the lateral direction, it is possible to further increase the printable content and the amount of information, and to print not only on the back surface of the cassette 1 but also on the label 1a on the top surface. It can also be applied to. Further, the printed contents are not only the contents that the VTR has (the contents stored in the timer unit 102), but the user can also use the input device such as the character generator to designate any character to record the recorded program. Title of
It is more convenient if the system is configured so that the year, month, and day of recording; and various information regarding audio signals can be printed. Furthermore, by using erasable printing (ink ribbon or the like) used in the printer mechanism 18, it is convenient when repeatedly erasing, recording, and reproducing the same tape cassette many times.

[0035]

Since the magnetic recording apparatus of the present invention is configured as described above, the user is free from the trouble of writing the recorded data and the like and the usability is improved. It has the excellent features of. In other words, just by looking at the label of the housing, the recorded contents such as the title of the program can be surely understood. For example, in the case of an unrecorded housing, how many minutes can be recorded and timer recording is surely performed. There is an effect that it is possible to determine at a glance whether or not it has been hit.
