1. A data storing means for storing data and for displaying said data at the request of an operator, comprising:
- a portable data display device for displaying data, said display device including a casing having a front face and a rear face spaced from the front face, first memory means for storing a control program, a first processing unit for generating control signals according to said control program and control signals from the outside, first receiving and transmitting means disposed within the casing for receiving airwave data and control signals from the outside and for transmitting data and control signals to the outside by airwave and having a first coil comprised of loops lying in a plane which is opposed to the rear face, a first capacitor connected electrically in parallel with said first coil, first modulating means for modulating data and control signals to electric signals to be transmitted to the outside, first demodulating means for demodulating electric signals generated by said first coil to data and control signals, and first switching means responsive to said first processing unit for activating said first demodulating means, second memory means for storing said data received by said first processing unit, switch means for requesting said first processing unit to display said data stored in said second memory means, display control means coacting with said first processing unit for generating display control signals representative of said data stored in said second memory means, and display means disposed adjacent to the front face in the casing and responsive to said display control signals for displaying on a display face thereof said data; and
an external controller for inputting data to be inputted in said display device, said controller including a keyboard for entering data to be set in said display device, third memory means for storing a control program, a second processing unit for generating control signals from said display device, second receiving and transmitting means for receiving airwave data and control signals from said display device and for transmitting data and control signals to said display device by airwave and having a second coil, a second capacitor connected electrically in parallel with said second coil, second modulating means for modulating data and control signals to electric signals to be transmitted to said display device, second demodulating means for demodulating electric signals generated by said second coil, and second switching means responsive to said second processing unit for activating said second demodulating means, fourth memory means for storing said data received by said second processing unit, and a holder having means for accommodating therein the second coil and for supporting thereon the rear face of the casing of said display device when said external controller transmits said data and control signals to said display device so that the display face of said display device can be viewed by an operator through the front face of the casing to enable the operator to view said inputted data and so that the first coil is closely electrically coupled to the second coil through the rear face of the casing.

Abstract
A data stored display device such as wrist watch comprises a central processing unit, a transmitting and receiving means for transmitting and receiving data and including a coil, RAMs written in and read out data under the control of the central processing unit, a display panel for displaying data stored in the RAMs and a stand-by switch for changing the transmitting and receiving means for non-transmitting and receiving condition to a transmitting and receiving condition so that the data stored display device can be inputted data from an external controller such as a computer having a transmitting and receiving coil and can function as a display panel of the external controller.
