Abstract

PURPOSE:To simplify a complicated switch operation, by providing a transparent switch to a display device and displaying characters with replacement on the display device for switching and in response to said transparent switch. CONSTITUTION:A transparent film switch 2 is provided on the surface of a cathod-ray tube (CRT) 1 which serves as a display device. A signal generating part 3 has a control to switch the input signal of an amplifier 4 functioning as an audio device in accordance with the signal given from the switch 2 and at the same time controls the characters displayed on the CRT 1. When the audio device is switched on, the type of signal shown by A is displayed at the position corresponding to the switch 2 of the CRT 1. Then a user pushes a switch 2' in response to the type of signal, and therefore the type of a cartridge is displayed as shown by B. In such a way, the types of selections which are carried out next are successively displayed at the position corresponding to the switch 2 on the display device in response to the operation of the switch. The part 3 controls the amplifier 4 with these operations of switches to obtain a state designated by the user.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an operating device for electrical equipment such as an audio amplifier or a tuner.

Conventional configuration and its problems Generally, audio amplifiers use a human switch.

There are a large number of switches such as a recording switch, cartridge selection switch, speaker selector, impedance selection, etc., and the switch locations (operation points) are also different, making it difficult to operate them.
There were many problems that made it difficult to fully operate and use it in a fully configured state.

OBJECTS OF THE INVENTION An object of the present invention is to provide an operating device for electrical equipment that can simplify complex switch operations, reduce erroneous operations, and perform accurate switch operations.

Structure of the Invention The operating device for electrical equipment of the present invention is provided with a transparent or translucent switch on a display, and displays the i-th character of the switch on the display in response to the switch. It is composed of According to such a configuration,
Display ;'::'i Since it is only necessary to operate the switch on the display while displaying the I- character, the switch operation can be simplified without complicating it.
It also has the advantage of reducing erroneous operations and allowing accurate switch operations.

DESCRIPTION OF EMBODIMENTS FIG. 1 shows an embodiment of the present invention. In the figure, 1 is a cathode ray tube as a display, 2 is a transparent film switch provided on the display mf of the cathode ray tube 1, and 3 is a transparent film switch provided on the display mf of the cathode ray tube 1. The amplifier 4 is a signal generator that generates character signals and control signals to the cathode ray tube 1 and the amplifier 4 according to the signal from the switch 2, and the amplifier 4 operates as a signal source 5 in response to the control signal from the signal generator 3. It is configured to control signals from a tape player, record player, tuner, etc., and drive the speaker 6. Here, the signal generating section 3 is specifically constructed as shown in FIG. In FIG. 2, the signal from the switch input terminal is decoded by a microgrossenother 11, and the address and data signals are transferred to the character generator 12, which is composed of a raw conductor MN1227 manufactured by Matsushita Electronics Co., Ltd., for example. Control signals for electronic polyurethane, electronic switches, etc. configured inside the amplifier 4 are outputted to the audio control output. As a result, the output of the character generator 12 is a red signal, a green signal, a blue signal as character signals, a horizontal output from the synchronization signal generator 13, and an IF direct output by the signal given by the microprocessor 11. Given the specific output, the two sets of display 1 show -;
Chie also f'L.

As a film switch, a piezoelectric element such as a polyfluoride film can be used, and a piezoelectric switch, a cabaret switch, etc. can be used.

In such a configuration, the

Display.

When recording, one of the film switches 2' to 2'' is operated as a recording selector switch, and when not recording, a film switch (not shown) is operated. Complex switch operations can be simplified by displaying characters corresponding to the film switches provided and configuring the display so that the character display corresponding to the film switch is updated every time the film switches are operated. It is possible to reduce the number of erroneous operations when operating the switch.

In addition, in FIG. 3, 2' to 2''' are the film switches of the display 1'' in FIG. is displayed at the film switch location on the display 1.

Here is the film Suinogoo 2', 2''.

As described in detail above, according to the invention, display 4) A transparent or translucent switch is provided on the ground, and corresponding to the switch, there are "two sets of indicators on the display" - the character of the switch. +tri IJy to update and display -.

Therefore, there is an advantage that complicated switch operations can be simplified and erroneous operations can be reduced.
