Abstract
Abstract An information output device basically comprises character output elements for visibly outputting at least one of characters such as letters, numbers, symbols, etc., a keyboard carrying thereon keys corresponding to the characters and usable for the selection of the characters, and a miniature body for containing therein the character output elements and the keyboard. Most of the size of the body is occupied by the keyboard. The character output elements may be printing devices for printing the characters on recording paper, or character display devices comprising a plurality of display elements for displaying the characters. The information output device may also include a control circuit for applying a control or driving signal to the printing devices or the display elements of the character display devices to cause the characters selected by the keys to be printed on the recording paper or to cause the display elements to successively display the characters selected by the keys. The body may also contain therein the control circuit.

Claim 5
Dependent Claim
50 words
A device according to claim 1, wherein said keyboard includes a back space key and control means responsive to actuation of said back space key, for feeding backwardly the recording medium relative to said head by a distance corresponding to one character by reversing the rotation of said rotatable platen.
Claim 6
Dependent Claim
69 words
A device according to claim 1, wherein said case is provided with a portion elevated above its keyboard accommodating portion, the elevated portion accommodating said print head, said device, further comprising: an adaptor, detachable from and attachable to said keyboard, provided with an opening engageable with said elevated portion of said case, and also provided with guide holes for guiding operator's fingers toward the top faces of said keys.
Claim 7
Dependent Claim
