Abstract

A portable general-purpose electronic apparatus which is characterized in that; a memory unit can be inserted into the housing via an inlet so that any desired display information memorized by the memory unit can be displayed on a screen display, and as a result, a variety of information can be conveniently displayed by merely changing the memory unit. Consequently, an extremely useful general-purpose electronic apparatus can be realized by memorizing any desired information, for example, such as game function and other data of interest.

Claims

1. A portable audio-visual electronic apparatus having at least three operational modes, including a first mode displaying still display information, a second made displaying a moving picture from still display information and a third mode displaying television signals, comprising

(a) means for visually displaying information including screen display means composed of a matrix of display elements;

(b) a semiconductor memory card for storing a sequence of distinct screens of still display information;

(c) a housing in which said screen display means is disposed and inlet lot in which said semiconductor memory card may be inserted;

(d) display control means in said housing for sequentially displaying said screens of still display information stored on said memory card on said screen display means after the memory card is inserted into said housing via said inlet slot when the apparatus is in the first mode, said display control means being capable of automatically sequencing said still display information in rapid succession to create the appearance of moving pictures on said screen display means when the apparatus is in the second mode;

(e) receiver means in said housing for receiving T.V. broadcast signals and outputting video signals; and

(f) mode selection means including a T.V. selection key for selecting video signals from said received means when the apparatus is in the third mode;

said display control means, in response to the actuation of said T.V. selection key, displaying said video signals on said screen display means rather than said still display information.

2. The portable electronic apparatus of claim 1, wherein said display control means includes a keyboard with manually actuable command keys for selectively sequencing each screen of still display information in a forward or reverse direction.

3. The portable electronic apparatus according to claim 1 wherein,

said memory card also stores audio information;

said control means reads said audio information from said memory card; and

there is further provided an audio speaker for outputting said audio information.

4. The portable electronic apparatus according to claim 3 wherein,

said receiver means also receives and outputs audio signals;

and

said control means in responding to the operation of said TV channel selection key outputs audio signals from said receiver means rather than from memory card.

5. The portable electronic apparatus of claim 3, wherein said audio information is speech.

6. The portable electronic apparatus according to claim 1 further including;

digital keys for inputting digital values and calculation keys for commanding calculations; and

calculation means for calculating digital values input in response to the operation of said digital and calculation keys; and

said control means enables said screen display means to display the results of calculations executed by said calculation means.
