Abstract

PURPOSE:To make it easy to confirm the display by displaying the function limited by the switching means on the display part which is located at an optional place, when the operation switch of an apparatus is selected. CONSTITUTION:At the initial stage when the power is turned on, the low frequency pulse of an inverter 22 to which waveform adjustment is made by an oscillator buffer 21 which keeps output to an exclusive OR gate 18 at high level, and outputs to other two exclusive OR gate 19, 20 at low level is supplied to one side of the terminals of liquid crystal displays 25, 26 and 27, and at the same time it is supplied to the gates 18-20. At this time, the gate 18 inverts the phase of the low frequency pulse inputted and outputs its result, while the other two gates 19, 20 output as the same phase. The outputs of the gates 18-20 are supplied to the other side of the electrodes of display panel 25-27, therefore, only the display panel 25 for which pulse of inversed phase is impressed between the electrodes is turned on and the other display panels 26, 27 are turned off. As a result, only the display of the display panel 25 is shown on the display device 12, and it becomes clear that the switches 13-16 are functioning as remote control switches.

Description

[Detailed description of the invention] Industrial applications It is related to.

Conventional configuration and its problems Conventionally, as shown in FIG. 1, a video camera has an electronic viewfinder 8 on the front l11 of the camera body.
An operating section 2 is provided below. The operation section 2 will be explained with reference to FIG. 2.The mode changeover switch 3 will be used to select the stopwatch mode 42, date and time display mode 5. You can switch to camera remote control mode 6, and if you click it, you can switch to stopwatch mode 4, and 0:00:00:O will be displayed on the monitor screen of the television CRT, etc., and then press switch 7a ( The timer of video camera 1 starts and the elapsed time is displayed on the monitor round screen.Press switch 7b to stop the timer, and press switch 7d to reset the time elapsed display to 0:00:00:O. Also, in time display mode 3 for the 1st, pressing switch 7a advances the year, and pressing switches 7b and 7
Each press of C advances the second day of the month. However, in this device, one operation switch has multiple functions, and these multiple functions are displayed by display information 4a-4d, such as letters and symbols, above or below the corresponding operation switch, respectively.
5a-sc and ea-6d, it is difficult to tell which function a single operation switch is operating when operating the camera, and it is necessary to look at the operation section 2 to confirm. The position of the video camera moves easily during shooting.

Further, as the number of functions increases, the area of the operating section 20 increases.

OBJECTS OF THE INVENTION It is an object of the present invention to provide an operating device which allows the user to freely select the necessary functions for operating equipment, allows simple function confirmation, and has good operability.

Structure of the Invention One aspect of the present invention is to divide a plurality of functions into a plurality of function groups in consideration of operating procedures, etc., and select an arbitrary function by a switching means, so that the functions constituting the function group can be displayed on a display. It is possible to operate each operation part that is linked to each displayed valley function, and only that function can be operated, and by placing the display in any position, it is possible to improve operability and make the display easier. This allows confirmation and miniaturization of the equipment.

Description of Leprosy Example A leprosy example of the present invention will be described below with reference to FIGS. 3 to 5. In FIG. 3, 11 is a control means;
Operation switch? 13, 14, 15° 16 and switching means (
Hereinafter referred to as a function changeover switch) 17 and an exclusive OR game) 18, 19, and 20 are connected. 12 is a display device, which is a liquid crystal display panel 25, 26, 27 shown in FIG.
It is a superposition of . This display is installed above the operation switches 13-16. 22 is an inverter, and a resistor 23 and a capacitor 24 constitute a low frequency oscillator for driving the liquid crystal. 21 is a buffer. Here, the liquid crystal display board 25 has function information symbols 25a to 25d in the remote control mode, and the liquid crystal display board 26 has function information characters 2.6a to 26d in the stopwatch mode.
The liquid crystal display board 27 has function information characters 27a to 27c in the date and time display mode.

Next, the operation of this operating device will be explained. Assuming that the operation switches 13, 14, 15, and 16 are set to function as remote control operation switches in the initial state when the power is turned on, the control circuit 11 sets the output to the exclusive OR gate 18 at a high level. The low-frequency pulse of the inverter 22, which is waveform-shaped by the oscillation lever sofa 21 that outputs to the other two exclusive OR gates 19 and 20 to a low level, is output to one side of the liquid crystal display board 25, 26, and 27. Exclusive OR gate 18.19゜2
o. At this time, the exclusive OR gate 18 reverses the phase of the supplied low frequency pulse and outputs it.
(exclusive OR game), 19.20 are output as they are in phase. Since the output of each exclusive OR gate 18, 19, 20 is supplied to the other electrode section of each liquid crystal display board 26, 26, 27, only the liquid crystal display board 26 receives pulses of opposite phase between the electrodes. lights up, and the other two liquid crystal display boards 26,
27 goes out. As a result, the display on the liquid crystal display board 26 appears on the display 12, and the operation switches 13, 14, 15.
It can be seen that 16 functions as a switch for remote control.

Next, press the function changeover switch 17 and press the operation switch 13.
, 14, 15, and 16 are switched to function as a stopwatch operation, the control circuit 11 sets the output to the exclusive OR gate 18 to a low level. LCD display board 2
Since the pulses marked between tJe and 4 of 6 change to the same phase, the liquid crystal display panel 26 turns off. At the same time, the control circuit 11 sets the output to the exclusive OR gate 19 to a zero level, so that pulses of opposite phase are applied to the five terminals of the liquid crystal display board 26, and the liquid crystal display board 26 lights up. As a result, the display 12
The display on the liquid crystal display board 26 appears, and the operation switch 13
, 14, 15, and 16 function as a stopwatch operation. A similar operation is performed on the liquid crystal display panel 27, and it appears on the display 12, indicating that the operation switch is set to f and l for date operation.

In addition to disposing the display device in correspondence with the operation switch on the operation section of the video camera, the display section 3o can also be detected and provided on the cathode ray tube 29 in the electronic viewing interface 28, as shown in FIG. . In this case, it is possible to improve operability, easily check the display, and downsize the device, which is extremely effective in practice.

As described above, the invention improves operability by displaying the functions limited by the switching means on a display placed at an arbitrary position when selecting the operation switch of a device such as a video camera. This has the advantage of allowing easy display confirmation and miniaturization of the device.
