Electronic device designed to permit detachable attachment of an external memory device thereto
First Claim
1. An electronic wrist watch device having means for permitting detachable installation of an external data storage medium, said electronic wrist watch having electronic circuitry means including a time-measuring section for measuring time and a display section for displaying the measured time, the electronic wrist watch further comprising:
- a substantially disk-shaped external data storage medium for storing data, said external data storage medium having output terminals for outputting said stored data;
a wrist watch case having a substantially columnar retaining section formed at an upper portion of said wrist watch case for accommodating said external data storage medium therein;
a cover member attached to said wrist watch case for opening and closing said retaining section, and for holding said external data storage medium retained in said retaining section when said cover member is in a closed position to close said retaining section, said cover member comprising an optical display device at an upper surface of said cover member such that said optical display device is viewable by a user when said cover member is in said closed position;
said electronic circuitry means further including means, for measuring a current time and for outputting a first display signal for displaying the current time, and means for receiving data stored in said external data storage medium and for supplying a second display signal based on the received data; and
signal transfer means for supplying said first and second display signals output from said electronic circuitry means to said optical display device.

Abstract
A wrist watch (1) is provided with a cover member (3) attached to a wrist watch case (2) by a coupling portion (3) in a openable/closable manner. A liquid crystal display device (4) to display time is incorporated in the cover member (3). A retaining section (7) for retaining a disk-like data memory is provided on the upper surface of the wrist watch case (2). The data memory in the retaining section (7) is securely held with the cover member (3) closed. Data in the disk memory (9) is read and processed by the electronic circuitry (2b) of a watch, and is sent to the liquid crystal display device (4) via a flexible circuit board (2e). The data is then converted into a time which is in turn displayed. The data memory can therefore be very easily attached or detached, and is securely held. The wrist watch itself can be made compact. Replacing the data memory with another one can provide advantages such as displaying various types of data.
