Since the timer reservation operation is very complicated, a separate one-touch timer button (4) is provided.

When this one-touch timer button (4) is pressed once, a part of the timer (2) is activated, and the recording operation is performed for, for example, 60 minutes from the time of recording. Press twice more to record 60 minutes, press six times to record 90 minutes...
... is being recorded.

Although the operation of such one-touch timer recording is extremely simple, on the other hand, the number of buttons for operating the timer is increased by one, making it easy to operate erroneously and making the structure complicated.

OBJECTS OF THE INVENTION In view of these conventional problems, an object of the present invention is to provide a recording/reproducing device that allows one-touch timer recording from the current time to a certain time later without adding a one-touch timer button. .

Summary of the Invention The recording and/or reproducing apparatus of the present invention includes means for detecting the number of operations of a recording or reproducing button, and a timer for setting the recording or reproducing operation time duration according to the number of operations detected by the detecting means. It is equipped with one means. With this configuration, one-touch timer operation can be performed without providing a special button.

Embodiment An embodiment of the recording/reproducing apparatus according to the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram of a part of a timer of a VTR showing an embodiment of a recording and/or reproducing apparatus according to the present invention.
The same parts as in FIG. 1 are given the same reference numerals. In FIG. 2, the aC recording button (6) of VTkL is also used as a one-touch timer recording button. This record button (
The operation output of 6) is output from the system control section (3) of the VTR.
), the recording operation of the VTR is controlled by the system control section (3). Further, the operation output of the record button (6) is sent to the timer section (2) via the system control section (3), and the recording time width is set in accordance with the number of operations. The set time span is displayed on the display (5)
will be displayed. The output of the timer part (2) is sent to the system control part (3), and control is performed such that the VTR performs a recording operation for a set time period from the time the record button (6) is operated.

The timer part (2) using a microcomputer has an existing timer function built in as shown in FIG. In FIG. 3, the current time TR of the clock circuit (2a) is stored in the register (2b), and the time setting is recording start time Ts.
is set extensively. Finally, Ts-TR is calculated from time to time and stored in the register (2g). These TR,T
The recording operation of the VTR from the start of recording to the end of recording is controlled based on information such as I and TS-TR.

The one-touch timer recording by pressing the record button (6) is as shown in the table below.

When the front record button (6) is pressed once for the first time, the normal B recording mode is set and recording is continued until the end of the tape. At this time, the timer display of the recording time is not displayed on the display section (5).

When the recording button (6) is pressed twice, the recording time of 60 minutes is displayed on the display section (5) and recording is started. After 30 minutes have passed, recording ends and the power is turned off.

Furthermore, each time you press the record button (6), the recording time increases by 60 minutes.
The settings are added minute by minute, and the total added time is shown on the display (5) as 60 minutes, 90 minutes, 1 song, etc. Furthermore, the maximum tape recording time of the VTR in this embodiment is 5 minutes. If you press the record button (6) again after setting up to 5 hours by pressing the button, the recording time will be programmed to return to the initial normal recording mode (recording to the end of the tape). There is.

Flowcharts for setting the one-touch recording time by pressing the recording button (6) described above are shown in FIGS. 4 and 5.

To explain the flowchart of time width setting in Fig. 4, when the record button (6) is pressed once in step aυ,
Contents Ts (recording start time) of register (2g) in Figure 6
-TR (current time) is set to 0, and register (2
Of e), gTE (recording end time) is set to TR (current time) ten infinity. As a result, normal recording mode (
(recording up to the end of the tape) is performed.

When the record button (6) is pressed one more time (second time) in step (121), the one-touch flag is set, the contents of the register (2e) are set to TE = 'I'R + 30, and the recording time is 60 minutes is set.

Next, in step tx'3I, press the record button (6) one more time (
6th time), the contents TB of register (2e) becomes TI
=TR+30×2. This sets the recording time to 60 minutes.

Thereafter, the recording time is set in multiples of 30 minutes in the same manner.

When the record button (6) is pressed for the (N-1) time in step (151) and the maximum recording time, for example 5 hours, is set, the record button (6) is pressed for the Nth time in the next step α6). Press the button to return to the original normal recording mode.

Next, the flowchart of the timer operation shown in FIG. 5 will be explained. In the timer part (2), register (2) in Figure 6 is used.
g) The contents of start time TS - current time TR are checked every moment, and when this becomes 0, part of the timer (2
) generates a recording mode signal and starts recording.

Therefore, as shown in FIG. 4, when the record button (6) is operated once, Ts -TR=O and recording is immediately started.

When the one-touch flag is set by pressing the record button (6) for the second time, the channel operation button is unlocked for one minute by a one-minute timer, and the TVi channel can be operated. After one minute has passed, the channel will be locked and you will not be able to change the channel while recording. Then, the recording operation is performed for a set time according to the number of times the recording button (6) is pressed.

If the record button (6) is not pressed twice or more, the one-touch flag will not be set, the channel operation button will be locked, and normal recording will be performed on the initially designated TV program channel.

In the timer part (2), the end time TE - current time TR is checked from time to time, and when Tl - TR becomes O, the power is turned off and recording ends.

In this embodiment, after entering the recording mode by operating the recording button (6), the recording time width can be set by operating the recording button (6) again and by the number of times the recording button (6) is operated.

Setting the recording time width based on the number of operations may be achieved by adding a certain amount of time (60 minutes) as in the embodiment, but for example, the first time is 60 minutes, the second time is 40 minutes, and the sixth time is 50 minutes.
A predetermined time period, such as a minute, may be set for each operation of the recording button (6).

The present invention can also be applied to the playback timer operation of a recording/playback device. Particularly in the case of a tape recorder, the playback time width may be specified by the number of times the playback button is operated, and this may be used for sleeve timer playback.

Effects of the Invention As described above, the present invention detects the number of times the record or playback button is operated, and sets the recording or playback operation time duration according to the number of times the button is operated, thereby eliminating the need for cumbersome timer setting operations. Further, without providing a special one-touch timer recording button like the conventional one on a part of the timer, the timer operation for recording or reproduction can be performed very easily. In addition, the structure of the timer operation section is simplified, reducing the possibility of erroneous operation.
