The operation of an electronic appliance, such as a cassette tape deck, is controlled completely or partially by switch operation. The appliance includes a memory for storage of control information, setting devices, such as switches, for entering the control information, a memory lock or latch for controlling the operating state of the appliance based on the control information supplied from the memory or from the setting devices to the memory lock, and for locking the appliance into such operating state, a display arrangement adapted for display of the setting information and for display of the information in the memory lock, and a setting change display indicator. The setting information stored in the memory can be checked by actuating a check switch, which causes the setting information stored in the memory to be displayed without affecting the operating state in which the appliance is locked. When the operating state is changed by a setting operation while the information previously stored in the memory has been transferred to the memory lock to control the operating state of the appliance, so that the contents of the memory lock (i.e., the operating state in which the appliance is locked) are not coincident with the corresponding information stored in the memory, the fact of such change is displayed on the setting change display indicator. This notifies an operator that the information is being changed, and assists the operator in avoiding unintentional errors. |

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide an electronic appliance that avoids the above-described disadvantages and difficulties of the prior art.
More particularly, it is an object of the present invention to provide an electronic appliance in which confirmation only of various stored information relating to settings of audio or other electronic appliances can be made easily, and in which, when any change has been made to the preset information, such change is displayed clearly to prevent operational errors and to simplify operation of the appliance.
It is another object of the present invention to provide an electronic appliance in which setting information may be displayed to permit a confirmation or check of the stored setting information without affecting the contents of the setting information when a particular selected operation is being carried out in the appliance, and in which, when a portion of an actual operation of the appliance is changed by actuating a selecting switch after the previously set information has been read out from a memory and the appliance has been activated into such actual operation, such setting change can be displayed clearly on setting change display means.
In accordance with one important aspect of the present invention, an electronic appliance has a plurality of elements which are selectively controlled in response to setting information, and includes a control panel having setting switches or other setting devices thereon, and display arrangements mounted thereon.
Setting information is entered on the setting switches, and a latch or memory lock connected to the setting switches receives such setting information and sets each of the elements into a setting state as established by the setting information entered on the setting switches.
The display arrangements are also coupled to the setting arrangements and are operative to display the setting information for each of the elements.
The improvements of this invention comprise a read switch, a write switch, a check switch, and memory means operative to receive and store the setting information contained in the latch upon actuation of the write switch and to cause the latch to receive and store the setting information contained in the memory means upon actuation of the read switch
