Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information recording apparatus for a recording cassette for recording video signals, audio signals, and the like.
[0002]
[Prior art]
Information recording apparatuses that record video signals, audio signals, and the like have been widely used for broadcasting or general home use. For example, a VTR cassette tape is used as an information recording device for recording video signals such as television and movies. An audio cassette tape is used as an information recording device for recording audio signals such as music.
[0003]
When recording information such as video signals and audio signals, these information recording devices usually have a title indicating the recorded content, a recording date, a recording time, a remaining time of the recording medium, the number of times of recording, the person who recorded the information, etc. The information related to the recorded content is stored in a visible manner. For example, the related information is written in characters on a label, and the label is affixed to a cassette tape body that is a recording medium or a case that protects the cassette tape body.
[0004]
[Problems to be solved by the invention]
In the conventional information recording apparatus, when displaying the information related to the recorded contents, as described above, the related information is written in characters on the label, and the label is attached to the cassette tape body or the case. For this reason, there are operations such as writing related information on a label or attaching a label to a cassette tape main body or case, which is complicated. In addition, when related information that has already been displayed is changed, it is necessary to rewrite the related information, or to replace the label.
[0005]
In addition, when the related information is displayed as characters on the label, the upper and lower characters are uniquely determined with respect to the cassette tape main body and the like. Therefore, if the cassette tape body or case layout is changed from vertical to horizontal, or changed from horizontal to vertical after the label has been attached, the top and bottom of the characters will be horizontal or upside down. It becomes difficult to interpret.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described drawbacks and to provide an information recording apparatus for a recording cassette that can easily display related information and read characters.

[0008]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIG. Reference numeral 11 denotes a recording cassette for recording a video signal and an audio signal, and a recording medium such as a semiconductor recording device is accommodated therein. Its shape is a rectangular parallelepiped, and the outside is composed of six rectangular walls. The recording cassette 11 has a structure that is hermetically sealed so that dust, dust and the like do not enter from the outside.
[0009]
A liquid crystal display device 12 is provided on the wall surface exposed to the outside of the recording cassette 11, for example, on the back surface. The liquid crystal display device 12 has a structure in which a display portion for displaying characters and the like is hierarchically configured by a plurality of layers, and a layer for displaying characters is switched. Then, using these display portions, information related to the recorded contents, for example, the title, the date of recording, the recording time, the remaining time of the recording medium, the number of times of recording, the person who recorded, etc. are displayed. . In FIG. 1, for example, the title 13 displayed on the uppermost layer and the recorded date 14 are shown.
[0010]
In addition to the semiconductor recording device using a highly integrated semiconductor, the recording cassette 11 houses an electric circuit for displaying related information on the liquid crystal display device 12.
[0011]
An input window 15 that transmits light is provided on a part of the wall surface of the recording cassette 11. A signal supplied from the outside passes through the input window 15 as an optical signal and is input to an electric circuit inside the recording cassette 11.
[0012]
Two switches SW1 and SW2 are provided at the right end of the drawing on the back of the recording cassette 11. One switch SW1 is used when switching a layer for displaying characters among the display portions of the liquid crystal display device 12 provided hierarchically. The other switch SW2 is used when the backlight is turned on at night or the like.
[0013]
Next, a configuration for displaying related information such as the title 13 and the recording date 14 on the liquid crystal display device 12 of the recording cassette 11 will be described with reference to FIG.
[0014]
Reference numeral 21 denotes an information input device, and an opening 22 is provided in a part of the information input device 21. The recording cassette 11 is inserted and set in the direction of arrow Y in FIG. The information input device 21 is provided with an input device, for example, a keyboard device 23, for inputting character information such as characters and numbers for displaying related information such as the title 13 and recording date 14.
[0015]
In the above-described configuration, character information for displaying the title 13 and the recording date 14 is input from the keyboard device 23. The input character information is converted into, for example, an optical signal via an input interface (not shown) provided in the information input device 21, and the electric information in the recording cassette 11 is passed through the input window 15 of the recording cassette 11. Input to the circuit.
[0016]
Here, the operation of displaying the related information on the liquid crystal display device 12 of the recording cassette 11 will be described with reference to FIG. In FIG. 3, parts corresponding to those in FIG. 1 and FIG.
[0017]
First, character information such as a title 13 and a recording date 14 displayed on the liquid crystal display device 12 is input from the keyboard device 23. The input character information is input to a signal processing device 31 in the recording cassette 11, for example, a central processing unit (CPU), via an input interface 24 provided in the information input device 21. The character information input to the signal processing device 31 is processed and converted into character data.
[0018]
Thereafter, the signal processing device 31 writes the converted character data in the memory 32. At the same time, the liquid crystal driving circuit 33 is controlled to display characters such as the title 13 and the recording date 14 on the liquid crystal display device 12.
[0019]
In the configuration described above, the plurality of horizontal sensors 34 a to 34 n are connected to the signal processing device 31 via the comparator 35. The plurality of horizontal sensors 34a to 34n are housed in the recording cassette 11, and the recording cassette 11 is placed horizontally with its longitudinal direction positioned horizontally as shown in FIG. 1, or as shown in FIG. The orientation of the recording cassette 11 is detected, for example, whether the longitudinal direction is set vertically or not. In FIG. 4, parts corresponding to those in FIG. 1 are denoted by the same reference numerals, and redundant description is omitted.
[0020]
For example, in the horizontal sensors 34a to 34n, as shown by the straight line P in FIG. 5, the angle (horizontal axis) with respect to the reference direction and the output (vertical axis) are in a proportional relationship. The outputs of the horizontal sensors 34a to 34n are input to the comparator 35 and compared with the reference value T. In this comparison, when the output is larger than the reference value T, it is determined that the recording cassette is arranged at right angles to the reference direction, for example, and when the output is smaller than the reference value T, it is determined to be parallel to the reference direction. In this way, it is always detected whether the recording cassette 11 is placed, for example, horizontally or vertically. The detection result is sent to the central processing unit 31.
[0021]
The central processing unit 31 controls the liquid crystal driving circuit 33 when the recording cassette 11 is changed from the horizontal position to the vertical position, or conversely, when the recording cassette 11 is changed from the vertical position to the horizontal position. Thereby, the direction of the characters displayed on the liquid crystal display device 12 is changed so that the upper and lower sides of the recording cassette 11 coincide with the upper and lower sides of the characters.
[0022]
If there is one horizontal sensor, the orientation of the recording cassette 11 may not be detected depending on the orientation in which the recording cassette 11 is placed. Therefore, a plurality of horizontal sensors are provided so that their reference directions are different from each other, and any horizontal sensor operates normally regardless of the orientation of the recording cassette 11, and the recording cassette 11 The direction and the change of the direction can be detected.
[0023]
In addition, when changing a character already displayed on the liquid crystal display device 12, the character information to be changed is input from the keyboard device 23. At this time, the signal processing device 31 compares the input character information with the character data recorded in the memory 32. If they are different, the recorded contents of the memory 32 are changed to the latest character data corresponding to the input character information. At the same time, the liquid crystal drive circuit 33 is driven to display the latest characters on the liquid crystal display device 12.
[0024]
Further, the switch SW1 is connected to the central processing unit 31. Since the display portion of the liquid crystal display device 12 is hierarchically configured, the layer for actually displaying characters can be switched by the switch SW1. For example, the operation of the central processing unit 31 is controlled by the operation of the switch SW1, and the uppermost character of the display portion is displayed, or the characters of the second and lower layers are displayed.
[0025]
The switch SW2 connected to the liquid crystal drive circuit 33 is used for lighting a backlight for nighttime. If the backlight is turned on, the characters displayed on the liquid crystal display device 12 can be read at night.
[0026]
In the recording cassette 11, a battery 36 for operating an electric circuit such as the central processing unit 31 and the memory 32 is disposed. A small lithium battery is suitable for the battery 36. However, it is also possible to use a charging type battery and supply power from the information input device 21.
[0027]
According to the configuration described above, it is possible to input character information using a keyboard device or the like and display related information on the liquid crystal display device of the recording cassette. For this reason, it is not necessary to write characters on the label or attach the label, and the related information can be easily displayed. Even if characters are once displayed on the liquid crystal display device, when the orientation of the recording cassette is changed, the recording cassette is automatically changed so that the upper and lower sides of the recording cassette coincide with the upper and lower sides of the characters. For this reason, it becomes easy to interpret the characters of the related information. A signal processing device such as a CPU is provided inside the cassette. Therefore, necessary information can be displayed immediately.
[0028]
In the above embodiment, the information input device is provided with the keyboard device. However, the keyboard device can also be configured independently. In addition, a liquid crystal display device is provided in a recording cassette containing a recording medium such as a semiconductor recording device. However, the liquid crystal display device may be provided in a case portion that houses and protects the recording cassette.
[0029]
Further, although a semiconductor recording device is used as a recording medium, a tape-shaped recording medium can also be used.
[0030]
