2. Description of the Related Art Conventionally, some video tape recorders are equipped with a timer recording device that automatically records a preset program when a preset time arrives. To operate a conventional timer recording device that has such functions, you need to set the program (channel) you want to record, the recording start time, and the recording end time, and then set the device to timer recording mode. There is a type (a simple type called a one-touch timer) in which you only need to set the desired program and recording end time.

In the former type, both the recording start time and recording end time must be set, so the setting procedure is complicated and it is difficult to use until you get used to it. With the latter type, you can schedule a recording just by setting the recording end time, making it easier to operate, but since the recording start time is limited to the current time, you cannot freely set the recording start time. This has the disadvantage that its usage is limited. Therefore, there is a type that allows you to easily set the recording start time and recording end time by simple key operations, for example, at 30 minute intervals, but even with this, you still have to set both the recording start time and recording end time. However, it had the disadvantage that it was cumbersome to operate when you were in a hurry.

[Problem to be Solved by the Invention] Some conventional timer recording devices require setting both the recording start time and recording end time, and others require setting only the recording end time. The disadvantage of this type was that the operating procedures were complicated and difficult to use until you got used to it. or,
In the latter type, the recording start time is limited to the current time, which has the drawback of being inconvenient to use.

Therefore, the present invention aims to eliminate the above-mentioned drawbacks, and makes the setting operation simple and reliable by allowing timer recording reservations by simply setting the recording start time without impairing the degree of freedom of timer recording. The purpose is to provide a timer recording device that can. [Structure of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the timer recording device of the present invention. 1 is a rotary dial for manually setting the recording start time; 2 is a waveform shaping circuit that shapes the waveform of the signal when the rotary dial 1 rotates in the forward direction; and 3 is a waveform that shapes the waveform of the signal when the rotary dial 1 rotates in the reverse direction. Shaping circuit, 4
is a microcomputer that performs control regarding timer scheduled recording, and includes a CPU 41, a memory 42, and a clock section 43. Reference numeral 5 denotes an operation unit that includes a reservation end key 51 that notifies the timer recording device of the end of the reservation, as well as various keys or buttons for operating the VTR equipped with this timer recording device, and 6 a recording target. A tape end detection circuit detects the tape end of the tape, 7 is a system control circuit for operating the VTR in various modes, and 8 is a system control circuit for detecting various information such as recording start time and recording channel. This is a display section for displaying information.

Here, a rotary dial 1, a waveform shaping circuit 2
, 3 and the microcomputer 4 serve as a time setting means, the clock section 43 serves as a clock means, and the CPU 41 serves as a determination means.
The tape end detection circuit 6 constitutes the second control means and the detection means.

Next, the operation of this embodiment will be explained. When the operator wishes to perform timer recording, he first operates the operation unit 5 to input channel information to the microcomputer 4 for recording. As a result, the CPU 41 of the microcomputer 4 stores the input channel in the memory 4.
Register for 2. Next, the operator rotates the rotary dial 1 to set the recording start time. This rotating dial is similar to setting the time on an analog watch, and if you turn it too far, you can simply reverse the rotating dial to correct the time. That is, when the rotary dial 1 is rotated, a signal for forward rotation is input to the microcomputer 4 via the waveform shaping circuit 2, and a signal for reverse rotation is input to the microcomputer via the waveform shaping circuit 3. 4 is input. The CPU 41 of the microcomputer 4 knows the set time by counting the number of forward rotation pulses or reverse rotation pulses generated with the rotation of the rotary dial 1 inputted from the waveform shaping circuit 2 or 3. The time at which the rotary dial 1 stops is set as the recording start time, and this is registered in the memory 42. At this time, since the CPU 41 displays the time information inputted as the rotary dial 1 rotates on the display section 8, the operator can confirm that the time displayed on the display section 8 is the desired recording start time. by the way,
All you have to do is stop the rotary dial 1.

After setting the recording start time as described above, the operator presses the reservation end key 51 on the operation section 5 to end the timer reservation operation. The CPU 41 is the reservation end key 5
When 1 is pressed, the device is put into a standby state via the system control circuit 7, and a comparison between the current time measured by the clock section 43 and the recording start time set in the memory 42 is started. do. After that, when the current time and the recording start time set in the memory 42 match, the CP
U41 puts the VTR into recording mode via the system control circuit 7, starts receiving the channels registered in the memory 42, and starts recording according to the reservation settings. In this way, when recording is started and the end of the currently set tape is reached, the tape end detection circuit 6 detects the end of the tape and detects this end in the microcomputer 4. Notify the CPU 41. When the CPU 41 learns that the end of the tape has been recorded, the system control circuit 7
to stop recording and return the device to standby mode.

FIG. 2 is a flowchart showing the timer recording process of the CPU 41 mentioned above. First, step 20
Step 1 waits for the recording start time to arrive, and when the recording start time arrives, the process proceeds to step 202, where the VTR is put into recording mode and a preset channel is recorded. At this time, it is determined in step 203 whether or not the tape end has been detected. If not, the process returns to step 202, and if the tape end has been detected, the process proceeds to step 204. In step 204, the recording operation of the VTR is stopped and the process returns to the standby state, and then the process is terminated.

According to this embodiment, if a tape with sufficient remaining tape capacity is set in the VTR in advance, all that is required is to set the channel to be recorded and the recording start time of this channel. You can perform timer scheduled recording. Therefore, the timer recording reservation operation can be simplified so that anyone can quickly and reliably set information regarding the timer recording reservation, and the operability when making the timer recording reservation can be improved. Moreover, in this example, since an arbitrary recording start time can be set, the use is not limited compared to the conventional one-touch timer recording method, and the degree of freedom of timer recording is not impaired. In the above embodiment, the rotary dial 1 is used to set the recording start time, but the recording start time may also be set using two keys: the up key to advance the time and the down key to go back to the time. A similar effect can be obtained.

[0014]

[Effects of the Invention] As described above, according to the timer recording device of the present invention, timer recording can be scheduled by simply setting the recording start time without impairing the degree of freedom of timer recording, making the timer recording setting operation easy. And it can be done reliably.
