A remote control signal processing device includes a signal receiving unit that receives a remote control signal from a remote control apparatus, demodulating means that generates and outputs signal data corresponding to the format and code of the received remote control signal, a memory unit for storing the signal data of the received remote control signal and having storage areas associated with control signals, operating keys that are associated with the storage areas and select the storage areas, a select switch selectively sets a recording mode or an operating mode, and a control unit which, when the select switch is set into the recording mode, writes the signal data of the received remote control signal into one of the storage areas associated with a depressed one of the operating keys and which, when the select switch is set into the operating mode, sequentially reads out the loaded signal data from the memory unit for comparison with the signal data of the received remote control signal, the control unit supplying a machine with control signals associated with the storage areas where the signal data found to match the received signal data has been written.

In the transmitter for remote control, a frequency at which an individual key switch is operated is counted, and a display formation of operation contents corresponding to the individual key switches is changed in accordance with the frequency. The changed operation contents are displayed by a display panel. The display formation includes the size, density, color, and sequence of operation menu displayed in the display panel. By using a transparent touch panel type display panel, an arrangement formation of the individual key switches can also be changed in accordance with the frequency at which they are used. The arrangement formation of the individual key switches includes the size and sequence of the individual key switches. In this way, an operator can easily find the operation menu on the display panel and easily operate key switches corresponding to frequently used key switches.

An output memory circuit device for and method of providing protection to an integrity of data stored in an external memory circuits during an output operation utilizing the data. Control means selectively controls activation of an external memory to an active state and an inactive back-up state, and obtains data from the external memory circuit during times corresponding to the active state. Storage circuit receives and temporarily stores data supplied by the control circuit and processing circuit receives and processes data fed from the storage circuit and outputs processed data to an output circuit. The control circuit selectively controls an activation of the external memory circuit to the inactive back-up state during times when receiving and processing is conducted to receive and process data fed from the storage circuit and output processed data to the output circuit.
