Abstract

PURPOSE:To select easily the desired action mode with one switch by responding to the operation of the switch, displaying successively an action mode at the prescribed sequence and time interval, responding to the second operation continuously and controlling the change-over of said equipment to the action mode displayed at the time of the second operation. CONSTITUTION:When a user pushes a switch 14, at a displaying device 15, action modes such as a recording (REC), a playing (PLAY), a fast feeding (FF), a rewinding (REW), a stopping (STOP), a pause (PAUSE), and an ejection (EJECT) are successively displayed by the prescribed sequence (for example, REW PLAY PAUSE...) and the constant time interval (for example, one second). When the desired action mode, for example, the playing (PLAY) appears at the displaying device 15, and the hands are taken off, the action mode 'PLAY' is selected and executed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mode switching device for equipment having a large number of operating modes, and more particularly to a mode switching device that allows a desired mode to be selected by one switch means.

BACKGROUND OF THE INVENTION Conventionally, devices that have multiple operating modes, such as video tape recorders (VTRs), have switching switches for recording, playback, fast-forwarding, rewinding, ejecting, and other operating modes to perform recording. To perform playback, the user operates the recording switch, and to perform playback, the playback switch is operated. In recent years, in response to diversifying tastes, a wide variety of functions have been added, such as freezing images and mixing external sounds, and accordingly, various switching or operation switches have been added to the operation panel.

Problems to be Solved by the Invention However, when such a large number of switches are installed, it becomes difficult for the user to identify the switches, making it inconvenient to use, and amateur users, such as the elderly, may feel a sense of discomfort or resistance. I'll hold you. Furthermore, manufacturing the device becomes troublesome.

The present invention has been made in view of the above-mentioned problems of the prior art, and provides a simple and user-friendly mode switching device that can easily select a desired operation mode with a single switch in equipment having multiple operation modes. The purpose is to

Means for Solving the Problems FIG. 1 is a block diagram of a mode switching device of the present invention.
In the figure, 1 is a switch means; 2 is a display means that can selectively display a large number of operation modes; 3 is a display means that responds to the first operation of the switch means 1, and displays operation modes one after another in a predetermined order and time interval. Mode display control means for displaying on display means 2; 4
responds to a second operation of the switch means 1 following the first operation, and controls each operating section 5 of the device so that the device switches to the operation mode displayed on the display means 2 at the time of the second operation. Ef, 7 (three as an example) are operation control means that provide control signals.

When switching the operating mode of the effect device, the switch means 1 is operated (for example, pressed). This first operation causes the switch means 1 to supply the signal S1 to the mode display control means 3. The mode display control means 3 receives this signal S! In response to this, the user supplies signals Ml, M2, etc. one after another in a predetermined order and at time intervals to cause the display means 2 to display the respective operation modes, when the desired operation mode Mi appears on the display means 2. At times, the switch means 1 is operated (for example, released). This second switch operation causes the switch means 1 to supply the signal S2 to the operation control means 4.

In response to this signal S2, the operation control means 4 reads the operation mode Ml from the mode display control means 3, and supplies control signals El, E2, and E3 instructing the operation mode Ml to the operation sections 5 and 6.7, respectively. do. As a result, the operating section 5. Ei, 7 operates to switch to operation mode Ml. Further, the operation control means 4 gives a control signal E4 to the mode display control means 3 to maintain the display of the operation mode Mi.

Embodiment A preferred embodiment of the present invention will be described with reference to FIGS. 2 to 5.

FIG. 2 shows a video tape recorder (VTR) to which an embodiment of the present invention is applied. In FIG. 2, a front panel 10a of the VTR10 is provided with an opening 12 for inserting and removing a cassette 11, and a power switch 13.
, a mode changeover switch 14, and a display, such as a fluorescent display tube 15, are provided.

To briefly explain the operation of this embodiment, when the user presses the switch 14, the display 15 displays record (REC), playback (PLAY), fast forward (FF), rewind (REW), stop (STOP), PAUSE, EJECT (
EJECT) etc. in a predetermined order (e.g. RE
W-PLAY→PAUSE...) and are displayed one after another at fixed time intervals (for example, 1 second). This is as if the display of operation modes arranged in a predetermined order circulates in the direction of arrow F, and the operation mode that has reached the position indicated by chain line G is displayed on display 15, as shown in FIG. It can be thought of as a thing. When the user releases the switch 14 when a desired operation mode, for example playback (PLAY), appears on the display 15, the operation mode rPLAYJ is selected and executed. And the display 15 shows rPLA.
YJ remains displayed.

FIG. 4 shows the configuration of this embodiment using a microcomputer. In FIG. 4, the output terminal of switch 14 is C
It is directly connected to the PU 16 , and the display 15 is connected to the CPU 16 via an interface 17 . Furthermore, CPU1B
A memory 18 is connected to the operating section of the VTR 10, that is, a head motor 19. Capstan motor 20° loading mechanism 21. Eject mechanism 22, recording circuit 23. A reproducing circuit 24 and the like (others are omitted) are connected. An appropriate interface (not shown) is added between each operating section and the CPU 1B.

The switch 14 generates an output signal of ``i II'' when it is pressed, and generates an output signal of ``0'' when it is not pressed. In addition to the control program, the memory 18 contains
Operation mode rRECJ, rPLAYJ, r
FFJ, rREWJ, rSTOPJ, rPAUsEJ,
A program for displaying rEJEcTJ in a predetermined order is stored.

The operating parts 19 to 24 have a normal configuration, and the head motor 1
9 rotates the head disk, a capstan motor 20 controls the tape running speed, and a loading mechanism 21
At the time of loading, the tape is pulled out from the cassette 11 and wound around more than half the circumference of the head cylinder. At the time of unloading, the eject mechanism 22 ejects the cassette 11 out of the opening 12, and the recording circuit 23
processes the recording signal during recording, and the playback circuit 24 processes the playback signal during playback.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG.

When the user loads the cassette 11 through the opening 12 after pressing the power switch 13 (FIG. 2), a cassette in signal of "l" is sent from the cassette switch (not shown in FIG. 4) to the CPU 16. In response to this, the CPU 18 enters the stop mode rsT.

P” is displayed on the display 15. In this case, the CPU 16 reads the display data M1 of "5TOP" from the memory 18, supplies it to the display 15, and sets it in the internal register IEta (steps 101 and 102).

Next, when the user presses the changeover switch 14 to perform playback, the output signal S of the switch 14 rises from "0" to "1", which is given to the CPU 18 as an interrupt signal, and the CPU 113 outputs the display data M1. The next display data M2 is read from the memory 18 and is supplied to the display 15 and set in the register IE3a (steps 103 and 104). The display order of the operation modes is set in advance by the program, for example, rsTOPJ→rREcJ.
→rEJEC:TJ→rREWJ→rPLAYJ→rP
If it is set in the order of AUsEJ → rFFJ,
Display data M2 is rREC1.

Therefore, the display operation mode of the display 15 is "5TOP".
J to rRECJ, but since this is not the user's desired operating mode rPLAYJ, the user continues to press the switch 14. Then, after - seconds have elapsed, the CPU 1B retrieves the next display data M3 from the memory 18.
Read rEJECTJ and display it on the display 15, set it in the internal register lea, and -
When a second has elapsed, rREWJ is set on the display in the same manner, and when one second has elapsed, rPLAYJ is displayed and set (steps 104, 105, and 104).

At this point, the user releases the switch 14 because the desired operation mode "rPLAY" appears (step 105).

As a result, the output signal S of the switch 14 changes from "■" to "
It rises to '0' and this is sent to the CPU as an interrupt signal.
Sent to 1B. The CPU 16 selects the operating mode rPLA displayed on the display 15 when receiving this interrupt signal.
YJ is read from the 8 registers lea, and the necessary control signal 8l-Silt for executing the playback mode is sent to the operating units 19 to 2.
Give to 4. As a result, the loading mechanism 21 pulls out the tape from the cassette 11 and winds it around the head cylinder, the head motor 19 and the capstan motor 20 begin to rotate to provide constant speed relative motion between the head and the tape, and the playback circuit 24 moves the tape from the head to the head cylinder. A reproduced video signal-audio signal is generated from the obtained RF multiplied signal (step 106).

Thereafter, the CPU 16 waits for the next mode change while continuing to display rPLAYJ on the display 15 (step 103). Then, when the user presses the switch 14 to stop the playback mode, the CPUIES operates in the same manner as described above, reads out the next display data rPAUsEJ from the memory 18, displays it on the display 15, and stores it in the internal register 16a. Set (step 104)
.

If the user continues to press switch 14, the CPU
16 displays and sets rFFJ after one second has elapsed, and displays and sets r ST OP, J after another second has elapsed (steps 105 and 104).

When the display on the display 15 switches to rsTOPJ, this is the user's desired operating mode, so the user releases the switch 14. As a result, the CPU 1B reads rsTOPJ from the internal register 16a in the same manner as described above, and sends the control signals 81 to S necessary to execute the stop mode.
6 is given to the operating parts 19-24. As a result, the head motor 19 and capstan motor 20 stop, tape running also stops, the playback circuit 24 becomes inactive, and the loading mechanism unloads the tape (step 10).
6).

Thereafter, the CPU 16 waits for the next mode change while continuing to display "5TOPJ" on the display 15 (step 103).Then, when the user presses the switch 14 to eject the cassette 11, in response C.P.
U1B is the display on the display 15 and the internal register IE3a
Switch the contents to the next display mode, rREcJ,
- Switch to rEJEcTJ for sand diameter (step 10
4105.104). Here, since the desired operation mode has appeared, the user releases the switch 14 and the CPU 1B
is the necessary control signal 8 to read “rEJECT” from the internal register 16a and eject the cassette 11.
1 to S6 are applied to the operating units 19 to 24. As a result, the eject mechanism 22 operates to eject the cassette 11 from the opening 11. (Step 106). As a result, a cassette Φ-in signal of "0" is sent from the cassette switch to the CPU 1B, and the CPU 16 turns the display 15 off.
F and terminates the operation of the entire device (step 108).
, 109).

Above, we have described the case where the user selects the playback operation mode, but even in the case of other operation modes, such as recording,
Press switch 14 in the same manner as described above, then display 1
If the switch 14 is released when rREcJ appears at 5, switching to recording is performed.

In the above-described embodiment, the order or cycle of displaying the operating modes is constant, but it is possible to set a plurality of orders -1, 1, and 1, and select an appropriate order according to the operating mode before switching. That's fine. In other words, the operation mode selected next to each operation mode is roughly fixed, and for example, the reproduction rP
Next to LAYJ is Bose rPAUSEJ or stop rSTOP
J is usually selected. Therefore, play rPLAY
When switching from the operation mode of
They may be displayed in the order of "F" → rEJECTJ → rRECJ. At this time, when the CPU 18 receives an interrupt signal from the switch 14, the contents of the internal register 16a (PL
By reading AY), the corresponding display mode order program is read from the memory 18. In this way, by giving priority to the display operation modes according to the frequency of use, rapid mode switching becomes possible.

Further, the present invention is not limited to the video tape recorder as described above, but is applicable to various devices having multiple operating modes.

Effects of the Invention 12. In the present invention, many operating modes can be selectively selected by simply operating a single switch, so it is possible to significantly reduce the number of switches provided on the operation panel of the device. Moreover, it is easy to use for users, especially elderly users, and furthermore, it is easy to manufacture the device.
