2. Description of the Related Art A VTR equipped with an autochanger device has a conventional timer operation management device. This allows multiple cassettes to be loaded to enable long-term recording. VT with this autochanger device
R can select a cassette to record for each timer reservation program, and for each cassette, it can be set in a timer standby state in which timer recording is possible, and in a timer standby state in which timer recording is not possible by canceling the timer standby state. You can set the timer release state. With this configuration, when a certain cassette is in the timer standby state, it becomes possible to record and reproduce other cassettes in the timer-released state, thereby improving usability.

[0003] In such a VTR, the timer standby state can be changed to the timer release state by a simple key operation.
During an input operation for a cassette whose timer is released, or during an input operation to change the timer standby state of a cassette other than the target cassette to the timer release state, change the timer standby state of the cassette whose timer recording must be made due to an erroneous operation to the timer release state. There was a possibility that it would happen.

[0004] For this reason, when the VTR is used by a user, the timer operation may become unreliable. For example, while user A sets the timer standby state and goes out, user B may leave the timer standby state set to the timer release state.

Furthermore, even if the VTR is not equipped with an autochanger device, it is possible to change the timer standby state to the timer release state with a simple key operation, so it is possible to change the timer standby state of a cassette whose timer recording must be performed by someone else's operation to the timer release state. There was a possibility that it would go away.

[0006]

As described above, the conventional apparatus has a problem in that any cassette in the timer standby state can easily be brought into the timer release state.

An object of the present invention is to eliminate the drawbacks of the prior art as described above, and to make it difficult for cassettes in which timer recording is highly important to change from the timer standby state to the timer release state due to erroneous operation.

Another object of this invention is to make it difficult for cassettes that require timer recording to change from a timer standby state to a timer release state due to an erroneous operation.

Embodiment First Embodiment A first embodiment of the present invention will be described in detail below with reference to FIG.

FIG. 1 is an overall block diagram of an embodiment of a VTR equipped with an autochanger device in which cassettes A and cassettes B can be selectively installed according to the present invention.

In FIG. 1, operation mode input means 1 outputs operation signals for setting operations such as playback, recording, and stop to recording/playback control means 2.

The cassette selection input means 4 selects which of the cassettes A and B that can be installed in the recording/playback control means 2, or selects both cassettes in chronological order in response to or irrespective of the timer reservation program. A selection signal for selecting whether to use a cassette is output to the recording/playback control means 2.

The recording/playback control means 2 selects either cassette A or B based on the selection signal, and schedules/reserves a determination signal 2a indicating the presence or absence of the currently selected cassette with a timer.
The signal is output to the execution means 3 and performs an operation based on the operation signal supplied from the operation mode input means 1. Further, when a reservation execution signal 3a, which will be described later, is supplied, the currently selected cassette is put into a standby state for timer recording, and recording starts and ends in response to this signal. Further, the recording/playback control means 2 includes a cassette changer mechanism (not shown), and this cassette changer mechanism includes two cassette storage sections,
A cassette transport mechanism is provided for selectively loading the stored cassettes into a tape drive system.

The priority setting means 21 outputs a priority signal indicating the priority levels of the two cassettes set by the user to the priority storage means 22. The priority storage means 22 stores a priority signal and outputs this priority signal to the timer reservation/execution means 3.

The reservation input means 11 outputs to the timer reservation/execution means 3 a reservation signal including the day of the week, channel, and recording start/end time input by the user.

The standby setting means 12 outputs to the timer reservation/execution means 3 a standby signal which is set by the user and puts the cassette currently selected by the recording/playback control means 2 into a timer standby state. The standby release means 13 sends a release signal set by the user to place the cassette currently selected by the recording/playback control means 2 in a timer release state.
Output to timer reservation/execution means 3. The standby signal of the standby setting means 12 and the release signal of the standby setting means 13 are set by the user pressing a button.

The time measuring means 31 measures the current time and outputs a time signal indicating the current time to the timer reservation/execution means 3.

The timer reservation/execution means 3 is provided with a storage device, and stores the supplied reservation signal in the built-in storage device. A standby signal, a release signal, a discrimination signal 2a, a time signal, and a priority signal are supplied, and based on the reservation signal and time signal, a reservation execution signal 3a is sent to select a cassette and start and end recording for recording/playback control. Output to means 2.

The operation of the apparatus configured as above will be explained.

Normally, if the reservation execution signal is not input, the recording/reproduction control means 2 selects a cassette based on a selection signal and performs an operation based on an operation signal.

When the standby signal is input to the timer reservation/execution means 3, the cassette currently selected by the recording/playback control means 2 is loaded, and the reservation signal for this cassette is stored. In this case, a timer standby state is immediately set, and the cassette selected by the recording/playback control means 2 is placed in a timer standby state.

[0027]The timer reservation/execution means 3 selects a cassette with a higher priority once the release signal is input when the recording/playback control means 2 is currently selecting a cassette with a lower priority. When the release signal is input twice while the timer is on, the timer standby state is released, and the cassette selected by the recording/playback control means 2 enters the timer release state.

Although this embodiment allows the user to determine the priority order, the present invention can also be applied to cases where the priority order is determined in advance. For example, the cassette stored in one of the two cassette storage parts of the cassette changer mechanism can be set as the priority cassette. Further, it is also possible to provide identification means for indicating that the cassette is a priority cassette on the housing of the cassette body, and to read this identification means to identify the priority cassette.

Further, in this embodiment, the number of selectable cassettes is two volumes, but the present invention can be applied to any number of volumes as long as there are two or more volumes, and to any number of priorities.

Furthermore, in this embodiment, the method of canceling the timer standby state of a cassette with a high priority is determined by the number of times the user presses the button that outputs a cancel signal indicating cancellation.
This may be continuous or discontinuous, and various other methods may be considered. For example, a plurality of different buttons may be pressed in sequence, or a plurality of buttons may be pressed simultaneously. Further, a separate button for this purpose may be provided, and the shape of the button may be changed. In this case, a door is attached to the button so that it cannot be easily operated. Alternatively, an ID number may be added so that the timer standby state cannot be canceled unless this number is input.

Furthermore, in this embodiment, when the number of cassettes in the reservation standby state is one volume, the reservation standby state is canceled by one standby/cancellation signal indicating cancellation regardless of the priority order, but the reservation standby state is canceled twice. The present invention is also applicable.

Second Embodiment A second embodiment of the present invention will now be described in detail with reference to FIG. 2.

FIG. 2 is an overall block diagram of an embodiment of a VTR to which one cassette can be attached according to the present invention.

In FIG. 2, the operation mode input means 41 records/records operation signals for setting operations such as playback, recording, and stop.
It is output to the reproduction control means 42.

The recording/reproduction control means 42 outputs a determination signal 42a indicating the presence or absence of a cassette to the timer reservation/execution means 43, and performs an operation based on the operation signal supplied from the operation mode input means 41. Further, when a reservation execution signal 43a, which will be described later, is supplied, the cassette is placed in a timer standby state, and recording starts and ends in response to this signal.

The protection level setting means 61 outputs a protection signal indicating the protection level of the cassette set by the user to the protection level storage means 62. The protection level storage means 62 stores the protection signal and outputs this protection signal to the timer reservation/execution means 43. That is, the operation of the timer standby and timer release means is selected and set.

The reservation input means 51 outputs a reservation signal input by the user, including the day of the week, channel, and recording start/end time, to the timer reservation/execution means 43.

The standby setting means 52 outputs a standby signal for setting the timer to a standby state to the timer reservation/execution means 43. The standby release means 53 outputs a release signal to the timer reservation/execution means 43 to set the timer to a release state. The standby signal of the standby setting means 52 and the release signal of the standby setting means 53 are set by the user pressing a button.

The time measuring means 71 measures the current time and outputs a time signal indicating the current time to the timer reservation/execution means 43.

The timer reservation/execution means 43 is provided with a storage device, and stores the supplied reservation signal in the built-in storage device. A standby signal, a release signal, a discrimination signal 2a, a time signal, and a protection signal are supplied, and based on the reservation signal and time signal, a reservation execution signal 43a for starting and ending recording is output to the recording/reproduction control means 42.

The operation of the apparatus configured as above will be explained.

Normally, the recording/reproduction control means 42 operates according to an operation signal unless a reservation execution signal is input.

When the standby signal is input, the timer reservation/execution means 43 immediately enters the timer standby state if a cassette is currently loaded in the recording/playback control means 42 and a reservation signal for this cassette is stored. become. As a result, the cassette loaded in the recording/playback control means 42 enters the timer standby state.

The timer reservation/execution means 43 enters the timer release state when the release signal is input once when the protection level is low, and when the release signal is input twice when the protection level is high. As a result, the cassette selected by the recording/playback control means 42 enters the timer release state.

[0045]

According to the present invention, when canceling a high-priority reservation standby state, the user can
Since the release signal must be set according to the priority, it is difficult to release the timer standby state due to erroneous operation for cassettes in which timer recording is highly important.
