Abstract

PURPOSE:To make arranging and editing easier without attaching an index label by providing a printing device constituted of a printing head and an ink ribbon on the back part of a video cassette and printing a date, time, the title of a photographing content, etc. CONSTITUTION:The character signal of the data and the title of the date of photographing, time, etc., is generated inside the camera, superimposed with a video signal, displayed on a screen and recorded on a tape. And at the same time, the character signals of them are sent to a printing head operation circuit and the printing device constituted of a printing head 1 and an ink ribbon 2 provided on the back part of a cassette case attached to the inside of the deck is operated. By this operation, the above-mentioned date, the time and the title are printed on a part for attaching an index label at the back surface of a case 4. Thus, without attaching the index label, the arranging and the editing are made easier.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prints character data such as the date, time, and title of the image taken by a VTR integrated camera on the back of a video cassette half to record a tape. It is related to usability that can be easily confirmed when editing or reproducing.

[0002]

2. Description of the Related Art In a VTR integrated camera or a still camera such as a single lens reflex camera, a date (date added / time added) function for recording the shooting date and time on a video tape or a film, and a shooting content. As you can see, there is a titler function that puts the title. This is to superimpose a character signal generated by a character generator (hereinafter referred to as CG) on a video signal and record it together with a subject. Generally, an on-screen display (hereinafter referred to as OSD) or a superimpose function. ,It is called.

The OSD will be briefly described. OS
The D function is to output a counter character, date, time, or any character on the electronic viewfinder (hereinafter referred to as an EVF) or a monitor screen in an overlapping manner with the video signal.

First, the output video signal is clamped at a constant DC potential. Next, the character signal pulse generated by CG and the above-mentioned video signal are added by a character signal addition circuit. Only the part where the character pulse is added is replaced with white or black, and the character appears to appear. The place to output the characters can be decided arbitrarily, but in the case of the title, it is large in the center of the screen, and the date and time are often displayed in the corner of the screen. When checking the date, time, contents, etc. of the tape recorded with the VTR integrated camera, it is magnetically recorded, so try playing it once or write it on the index label in advance and stick it on the case. It had to be done, and it took time and effort.

[0005] As an example of the present invention, as a reference for superimposing, "Transistor Technology 90-December" issued by CQ Publishing Co. (P. 54).
1-P. 548).

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a title, date and time, which are magnetically recorded on a video tape as described in the above-mentioned conventional example, on the back of the cassette case. By printing at the same time, the confirmation of the tape contents is improved and the efficiency of editing work is improved.

[0007]

[Means for Solving the Problems] In order to achieve the above object, necessary information such as title, date, time, etc. at the time of taking a picture of a camera is recorded on a tape, and at the same time, on a side or a back of a cassette case. I tried to print it. Further, the print head is moved for each printing to change the character position so that the printed characters are not overwritten.

[0008]

[Function] Whether or not to output the 0SD character such as date and time is determined by the date (year / month / day / time display) of the camera body.
Turn on / off with a switch. When the switch is turned on, the OSD character output and the printing function are activated, and necessary data such as the date, time, etc. is printed on the side or back of the cassette case. For printing, the print head used in a printer or the like is built in the VTR (on the side when the cassette case is loaded, or on the rear) and printing is performed. The position of the characters to be printed should be moved for each printing to prevent overwriting and obscuring.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 shows that a printing apparatus including a print head 1 and an ink ribbon 2 is provided in a deck portion of a VTR integrated camera. First, the date and time at the time of shooting are displayed on the screen using the date switch on the camera body. FIG. 2 shows the state of the screen (the screen displayed on the EVF) at this time. 5 indicates the date, 6 indicates the time, and 7 indicates the counter character. If you do not want to display the date and time, you can press the date switch again to turn off the date. Generally, if the date and time are displayed during shooting, they will be recorded as they are with the video, and if not displayed, nothing will be recorded. Printing on the cassette case is performed in conjunction with this date switch.

Next, the printing operation will be described. Figure 1
The ink ribbon 2 is provided between the back of the loaded cassette case 4 and the print head 1. When the print head 1 hits the ink ribbon 2 toward the cassette case surface, the title,
The date and time are printed. FIG. 3 shows a block diagram of the printing operation. The character data generated by CG11 is
At the same time as being sent to the character signal adding circuit 12, it is also sent to the print head operating circuit 13. The sent character data is read, the print head 1 strikes the ink ribbon 2, and the title and date are printed on the back of the cassette case 4. FIG. 4 shows a state in which the date is printed on the back of the cassette case 4. The place to print is the place 10 to which the index label is attached, and as shown in FIG. 4, printing is performed from the upper left as viewed from the back of the cassette case.
In addition, the print head moves each time printing is performed so that printing is not performed in an overlapping manner, and printing is performed at different positions.

[0012]

According to the present invention, the contents, date and time of the recorded tape can be easily confirmed, the tape can be organized without attaching the index label, and the editing can be easily performed.
