Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to a program information input device that can be used to control the recording/reproducing operation of a recording/reproducing III device such as a tape recorder or a video tape recorder.

Problems with the configuration of conventional examples In recent years, for example, video tape recorders (hereinafter referred to as VTRs), which are recording and reproducing devices for consumer equipment, have been introduced as stationary VTRs with a new function added with a program recording function. has become popular. Fig. 1 is an external view of this conventional program function (tVTR).The front panel of the VTR1 has a slide switch type switching means 2 that can switch between the first mode and the second mode, and a program function. Input means 3 for inputting information are provided. FIG. 2 shows the switching means 2 in the first mode, and FIG. 3 shows the switching means 2 in the second mode. It shows.

FIG. 4 is a block diagram of V T l'< in FIG. This is the VTR body whose operation is switched.

A conventional program information input HV'il comprising switching means 2, input means 3 and storage means 4 will be explained in detail based on FIG. When the first switching stage 2 is in the second mode shown in FIG. In this mode, information cannot be written into the storage means 4 via the input means 3. In the conventional configuration as shown in -1- below, when recording a program, first the switching means 2 is switched on.
into the second mode as shown in FIG. When the switching means 2 is in the second mode as described above, the f1.1 gram information can be input into the storage means 4 via the input means 3! Then, in this state, use the input means 3.
1 gram information (for example, channel, recording start time, etc.) is written into the storage means 4.

After completing the necessary 1-1 gram information manually, switching means 2
is returned to the first mode shown in FIG. This first mode C attempts to input the program information via the human power means 33. Since it is difficult to input the program information into the storage means 4, the human power means 3 is operated unnecessarily. The program information written in the storage means 4 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 control means 5
The VTR main body 6 enters the recording state via the , and can automatically start recording.

However, in the conventional program information input device, even if the above-mentioned operation is performed, someone (for example, a child) may accidentally touch the switching means 2 without knowing anything before reaching the set recording start time, and the second switching means 2 may be accidentally touched. If the input 1 stage 3 is touched again, the program information previously written in the storage means 4 will be destroyed, making it impossible to record the desired number, which is a serious problem. Occur.

Purpose of the Invention The present invention prevents necessary program information input by an information inputter from being accidentally destroyed, stores and retains information input by an information inputter more safely and reliably, and reliably records according to the information. The purpose of this invention is to provide a program information system that can control the recording and reproducing operations of a reproducing apparatus.

Structure of the Invention The program information input device of the present invention includes a switching means having a first aspect and a second aspect, and the switching element NU/J'.
The first aspect is followed by the second aspect, which includes a detection means for detecting the program 1 gram write mode, and a program information system for specifying program content by detecting the program 1 gram write mode. Ii person) Provides an input means that enables J and a storage means that memorizes the program information inputted through this input means, and stores the block stored in this storage means. [] Control one state for recording/reproducing the Durham information in the recording/reproducing device 911' (8
This is limited to the case where the switching means is set to the first mode and then to the second mode. Preventing information from being destroyed 11 - [C] Information entered by information personnel can be stored more safely and reliably, and the stored information can be followed (characterized by the ability to reliably control the recording and reproducing device). Ru.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to 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.
is the same as the conventional example shown in FIG. In FIG. 5, the program information input device B includes a switching means 2 capable of switching between a first mode and a second mode, an input stage 3 for inputting program information, and a switching means 2. It is composed of a detection means 7 for detecting a specific operating state of the device, and the storage means 4. FIG. 6 shows the switching means 2 in the first mode, and FIG. 7 shows the cutting means 2 in the second mode.

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

The detection means 7 determines whether the program is accepted or not only when the switching means 2 takes the first mode shown in FIG. 6 and then takes the second mode shown in FIG. , the platform 1Jl that first detected the operation of the human-powered means 2 first assumes the first mode and then changes to the second mode, even if the platform changes to the second mode after the first mode. [1g) In order not to judge it as Muoka infiltration mode, such a detection means 7 is connected to the logic 111 circuit.
It can be easily achieved.

Furthermore, when the human power means 3' is operated in a state where the detection means 7 determines that the program 21 has been inserted, the operated content is written into the storage means 4 as program information. .

The program 6M of this example is configured in
function (NIV 1-H program write operation,
The case in which the switching stage 2 is initially in the second mode and the effect in the first mode will be explained in detail.

(Interval in the second mode) - In the second case, first change the switching means 2 from the second mode to the 0th mode.
Shown in the diagram! 1 Return to the first aspect. Then, the switch rQ2 is placed in the second configuration shown in FIG. By performing the above two operations, the detection means 7 determines that the program writing mode is in effect, and then, when program information such as booyan channel and recording start time is inputted via the input means 3', the program information is the storage means 4
is maintained.

When the writing of the necessary program information to the storage means 4 is completed in this way, the switching means 2 is switched to the first switch shown in FIG.
Keep it in this mode. This is because, even if you try to input program information by scanning the input means 3' in this state,
Since the detection means 7 has not determined that the program writing mode is set, the program information is stored in the storage means 4 again.
There is no possibility that the lc information will be destroyed by inputting it first.

(When in the first mode) In this case, the switching means means 2 is once set to the second mode,
Next, by performing the same operation as described above [in the case of the second mode], the gramogram information can be written in the storage section 4.

In this way, when the program information is written in accordance with the respective procedures (in the case of the first aspect) and [in the case of the second aspect], the control means j is stored and retained in the storage means 4. When the set recording start time is reached according to the program information, V-r+'< the main body 6 is placed in the recording state of a predetermined channel, and recording can be performed automatically.

As described in the detailed description of the invention, according to the program information input device of the present invention, only when the switching means is in the first mode and then in the second mode, it is determined that the program is in the program writing mode, and the input device inputs the program information. Since the configuration allows W1 to input the program into the 10I° stage, it is possible to more reliably prevent the information input by the program information input person from being destroyed by 16, and to prevent the program information input from being destroyed. The recording and reproducing device is set to 1 according to the program information manually created by the person.
．． 1 () Can be reliably controlled.
