Class Information
Number: 400
Name: Typewriting machines >
Description: This is the generic class for an apparatus wherein a user of the apparatus causes an intelligible character* to be imprinted on a record-medium* by a type-member* that is impressed on the record-medium, said type-member being selected from a plurality of different type-members, and the selected type-members being impressed serially to form a sequence of characters that record intelligible information.
