Abstract

PURPOSE:To prevent destruction of input information in error and to attain control by allowing a mode detecting means to permit the input of program information through the detection of a program write mode and allowing an information detecting means to detect the end of input so as to inhibit the input. CONSTITUTION:A program information input device I' consists of a switching means 2, an input means 3' inputting program information, a mode detecting means 7, an information detecting means 8 and a storage means 4, and a VTR main body 6 is controlled by the program information stored and held in the means 4 via a control means 5. When the means 2 takes the 2nd mode, the means 7 takes once the 1st mode and then takes the 2nd mode, thereby decides the program write mode. When the means 7 decides the write mode and permits the write to the means 4 and then the means 8 detects the end of input of information, the means 3' inhibits the write of the means 4. Thus, destruction of input information in error is prevented in this way.

Based on FIG. 4, a conventional program information device I comprising a switching means 2, an input means 3, a storage means 4, etc. will be explained in detail. When the switching means 2 is in the second mode not shown in FIG. Input means 3 when
It is configured such that information cannot be written to the storage means 4 via the storage means 4. In the conventional configuration as described above,
When recording a program, the switching means 2 is first set to the second mode shown in FIG. When the J: sea urchin switching means 2 is in the second mode, it is possible to input the 1 gram information into the storage means 4 via the input means 3. Program information [e.g. ヂ1? channel, recording start time, etc.] are written into the storage means 4.

After inputting the necessary program information, the switching means 2 is returned to the first mode shown in FIG. In this first aspect, even if program information is attempted to be input via the input means 3, it cannot be input into the storage means 4, so even if the input means 3 is carelessly operated, the program information is not written into the storage means 4 first. Program information is protected from destruction. According to the program information written in the storage means 4 in this way, when the set recording start time is reached, the V
The TR body 6 enters the recording state and can automatically record.

However, in conventional program information manual devices, even if the above-mentioned operation is performed, someone (for example, a child) may accidentally touch the switching means 2 without knowing anything before the set recording start time is reached, and the second If you touch the input means 3 again, the data will be written to the storage means 4 first and the C
The program information stored in the program will be destroyed, resulting in a serious problem in which you will not be able to record the program you want.

M:, B [Unnecessary if you forget to return the switching means 2 to the first mode after completing the input/output of 1 gram information)
If the input means 3 is touched, the program information in the storage means 4 will be destroyed.

Purpose of the invention 4 (The invention is to prevent necessary program information inputted by an information inputter from being accidentally destroyed, to store and retain information inputted by an information inputter more safely and reliably, and to reliably follow the information. The purpose is to provide a 1-gram information manual system that can control the recording and playback operations of a recording/reproducing device.

Structure of the Invention The /LIgram information input device of the present invention includes a switching means for switching between a first mode and a second mode, and a switch for switching between a first mode and a second mode, and a switch for switching between a first mode and a second mode. Next, it is detected that the second mode has been adopted and the program writing mode is determined, and when the switching means is not in the second mode, it is detected that the second mode has been changed and the program writing mode is selected. a storage means for storing program information; an information detection means for detecting that program information of a predetermined item has been written in the storage means and determining that information input is completed; The means detects a program writing mode to permit input of program information to the storage means, and the information detection means detects completion of information input and prohibits input of 1 gram information to the storage means. input means is provided, and the program information stored in the storage means is used as a signal for controlling the recording/reproduction state of the recording/reproducing apparatus, and even if the switching means is left in the program input mode, the predetermined items can be changed. By canceling the program write mode when the program is finished, the necessary program information is prevented from being destroyed inadvertently, and the information entered by the information inputter is stored more safely and reliably, and the memory is retained. It is characterized by being able to reliably control the recording/reproducing device according to the information being displayed.

DESCRIPTION OF THE EMBODIMENT An embodiment of the present invention will be explained based on FIGS. 5 to 7.

FIG. 5 is a block diagram showing the main parts of a program recording function (tVTR) equipped with the program information input device of the present invention.
The main body 6 is the same as the conventional example shown in FIG. In FIG. 5, the program information input device I' includes a switching means 2 capable of switching between a first mode and a second mode, an input means 3' for inputting program information manually, and a switching means. The information detecting means 8 detects the completion of recording of a predetermined item, and the storage means 4. FIG. 6 shows the switching means 2 in the first mode, and FIG. 7 shows the switching means 2 in the second mode.

Next, the configurations of the mode detection means 7, information detection means (3, and input means 3') will be explained in detail based on their operations.

The mode detection stage 7 detects that when the switching means 2 takes the second mode as shown in FIG. 7, the switching means 2 temporarily takes the first mode not shown in FIG. When the switching means 2 is in the first mode shown in FIG. The device is configured to determine that it is in the gram output mode, and such mode detection means 7 can be easily realized with a logic circuit.

The information detection means 8 detects that all predetermined items (for example, date and time, recording channel, recording period, etc.) necessary for executing one task have been written in the storage means 4, and ends the information input. It is configured to determine that.

The input means 3' determines that the mode detection means 7 is in the 11-cogram write mode and is permitted to write the program into the storage means 4, and when the information detection means 8 detects the end of information input, the input means 3' writes the program to the storage means 4. This prohibition is canceled when the state detecting means 7 detects that the program write mode is again set.

The V with program function of this embodiment configured as described above
The program writing operation of TR will be explained separately for the case where the first switching stage 2 is initially in the second mode and the case where it is in the first mode.

[In the case of the second mode] In this case, first, the switching means 2 is changed from the second mode to the first mode as shown in FIG. Next, the switching means 2 is placed in the second mode shown in FIG. By performing the above two operations, the mode N% II means 7 determines that it is in the program writing mode, and then inputs program information such as chitunnel and recording start time through the input means 3'. The program information (b) is stored and held in the storage means 4. When the necessary program information has been input into the recording means 4 in this way, the switching means 2 is set to the first mode shown in FIG.

[In the case of the first aspect] In this case, the switching means 2 is set to the second mode.

Lee's F! , Sung, mode detection means 7 determines that the mode is program writing mode, program information can be input into storage means 4 via input means 3', and when the input of program information is completed, switching means 2 is switched to the first mode. If you keep it in the form,
Can be recorded.

In this way, the control means 5 is stored and retained in the storage means 4 by writing the program information according to the respective procedures (in the case of the first aspect) and (in the case of the second aspect). When the set recording start time is reached according to the program information, the VTR body 6 enters the recording state of a predetermined channel and can automatically record the video.

Further, in the above operation explanation, even if the switching means 2 is left in the second mode by mistake after the necessary program information is input manually through the input means 3' and the IC is turned on, it is possible to perform one task. When all the necessary predetermined items [1] of the program information have been written into the storage means 4, the information detection means 8 detects the end of the information input, so J:
・], it is prohibited to insert J: into manual means 3′ and τJ3
Even if someone (for example, a child) accidentally touches the input means 3' before the set time to start recording is reached, the program information that was previously written by the person will not be destroyed. It is possible to safely store and hold data without any problems, and it is possible to reliably record when the recording start time is reached.

In the first embodiment, the switching means 2 has been described as being of a sliding type similar to the conventional one, but this can also be implemented in the same way by using a push button type.

As described in the detailed description of the invention, the program information manual device of the present invention enters the program information write mode (as soon as the writing of a predetermined item to the first storage stage is completed, writing by manual means to the storage means is prohibited. Because I configured it to
Even if you forget to cancel the program information writing mode, the program information entry mode will be automatically canceled, and even if the input means is touched carelessly, the information inputter will still be able to input the necessary information. The information entered by the information inputter can be stored more safely and reliably in the storage means without any destruction.
), the recording/reproducing device can be reliably controlled according to the program information.
