Abstract: A printer for use in an office machine having a keyboard and including a typing element carrying type faces of the characters to be printed and mounted on a carriage for displacement along a line printing path and being rotatable to bring a selected type face into a printing position, and a control device responsive to signals from the keyboard and operative, immediately after a type face is brought into the printing position and before printing of the associated character, for effecting rotation of the typing element in a predetermined direction over a path of predetermined length and then in the direction opposite to the predetermined direction and over a path of the same predetermined length.

Abstract: Erase apparatus for a typewriter utilizes a special double strike technique to permit quality erasures at normal character overstrike accuracies. The unwanted character is overstruck first slightly to one side and then slightly to the other side in the escapement direction. A preferred range to achieve apparently complete erasures occurs at sideshift distances between two and twenty percent of an average character escapement. In a presently preferred implementation, position codes are produced which cause the normal typewriter escapement apparatus to move the type carrier to the special striking positions for erasing.

Abstract: Low tack pressure sensitive compositions containing polyethylene, a tackifier, an isobutylene polymer, a copolymer of ethylene and/or propylene and a monoethylenically unsaturated ester and a carboxylic acid and/or ester thereof and use thereof to remove erroneously typed images from a substrate.

Abstract: According to the present editing printer, a printing head can print either on the first insertion line or on the second ordinary line by the operation of a keyboard, and the characters from the keyboard are also stored in a memory. An insertion end sign " " is printed at the end of the insertion characters on the first line. A group of characters from the first character to the character before the insertion end sign on the first line are inserted automatically in the second ordinary line by the aid of the memory, which provides clean output with no error after editing.

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.

Abstract: A conventional single element IBM correcting SELECTRIC typewriter having an error correction system is modified by adding to the element a universal obliterating type font and providing an error correcting key function which is independent of the other keys.In the SELECTRIC typewriter the error correcting key is operatively connected with the backspace key so that activation of the error correcting key simultaneously activates the backspace key.

Abstract: A correction device for typewriters and the like, including a material, preferably in liquid form, maintained at a predetermined pressure within a container. The container outlet is coupled through a narrow elongated tube whose dispensing end is positioned upon the typewriter carriage or other device so as to be located immediately across from the last printed character or other symbol. An operating switch activates an electronic circuit for dispensing a measured amount of the material over the last printed character, the color of said material being the same as the paper being printed upon to provide the same effect as erasure of the character. The dispensing of the measured dosage may be accomplished either by electronic or mechanical means. The erasure means may be provided as an integral part of the typewriter unit or as an independent stand-alone accessory.

Abstract: A printing ribbon is composed of a printing portion and a correction portion welded together and extending parallel to each other. The correction portion lies in the plane of the printing portion which is the thickest portion of the ribbon and constitutes only a single thickness of inked fabric.
