An upper housing member having a keyboard, a visible display and function switches on the upper portion thereof and a bottom portion incorporating an acoustical coupler device for removably receiving a telephone handset is pivotally connected at one end to a lower housing member having a top portion incorporating a spring-loaded telephone handset cradle means for supporting the telephone handset received by the coupler device when the cradle mechanism is in an operative position. The cradle mechanism includes a spring-biased cradle plate pivotally mounted in a central cavity in the lower housing member which is automatically extended to the operative position when the device is opened.
