Relates to a video signal reproducing device in which the information is used as a key switch operating method relating to reproduction.

[0002]

2. Description of the Related Art One of the conventional techniques for facilitating the operation of a child when he or she operates the device is:
There is a "picture display music selection key for compact disc players" that was proposed as an issue. In this technology, it is shown that the display engraved on the music selection key for selecting a track to be played is not a numeric display but a display such as a picture, a color, and a character that is suitable for infants and children (No. 1 of the prior art).

Further, as one of reproducing apparatuses for superimposing character information on an image reproduced from a recording medium, Japanese Patent Laid-Open No. 4-1328 / 1992 has been proposed.
There is a karaoke device proposed as No. 8. In this technology, for each stored song, original lyrics data using Kanji and Hiragana, lyrics data using only Hiragana, lyrics data using only Katakana, or English lyrics data, etc. Stores multiple types of lyrics data. When the karaoke piece is played, one of the original lyrics using kanji and hiragana, the lyrics using only hiragana, the lyrics using only katakana, or the English lyrics according to the operation of the changeover switch. Is displayed on the screen (referred to as second related art).

Further, in the prior art "commuter ticket issuing machine" proposed as Japanese Patent Laid-Open No. 9-180008,
Whether the user is an adult or a child is determined based on the information read from the old commuter pass or the information input by the user. Then, when the discrimination result is an adult, the display method of the display device is a kanji mixed mode, and when the discrimination result is a child, the display method is a hiragana main mode (referred to as a third conventional technique).

Further, in the "multilingual recording medium" which is a conventional technique proposed as Japanese Patent Laid-Open No. 10-208446, a plurality of captions displayed on a moving picture screen are displayed in one of a plurality of languages.

Displayed on the screen. On the other hand, when the stop key 23 is operated in the state where the information indicated by 71 is displayed, as shown in FIG. 73, in the upper right portion of the screen, the information indicating “no further reproduction” is displayed for a predetermined period, and A menu screen (not shown) is displayed. When the reproduction key 21 is operated in this state, reproduction from the head position is started.

This concludes the explanation for the adult mode,
Next, the case of the lower grades mode in the child mode will be described.

It is assumed that the child mode is set to the lower grades mode by a predetermined operation of the key switch of the remote controller 8. It is also assumed that the reproducing means 1 is performing a reproducing operation. When the pause key 22 is operated in this state, the control means 2 pauses the reproduction operation of the reproduction means 1. Further, the OSD circuit 4 is caused to generate an information signal indicating the operation method of the key switches 21 to 23 with a sentence in which the function marks 214, 224, and 234 are mixed in the main hiragana sentence. For this reason, the display device 7 is shown in FIG.
