Abstract
Abstract A psychograph, of a type employing a movable indicator to designate indicia on a principal part of the device such as a board, can be constructed so that the indicator will cause a switch to close each time it points to or otherwise designates an indicia. A circuit is used to provide an output in the form of a signal capable of being stored or used by a computer, an electronic typewriter or the like when a switch is closed for a pedetermined time interval. Normally the board or similar part of the device will carry a plurality of indicia and a separate switch will be associated with each so that signals corresponding to all of the indicia can be obtained.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
229 words
In a psychograph having a board, a plurality of visually apparent indicia located on said board and an indicator which is adapted to be moved relative to the surface of said board to designate successive of said indicia in order to express a communication in which the improvement comprises: said visually apparent indicia including indicia representing the letters of the alphabet, punctuation means and a space between letters, a switch means located on said board in association with each of said visually apparent indicia, actuating means for sequentially closing individual of said switch means when a sequence of said visually apparent indicia are designated by said indicator, said actuating means being located on said indicator so as to be movable therewith, circuit means for providing a signal capable of being used to obtain a record of said visually apparent indicia designated by said indicator in the sequence in which said visually apparent indicia are designated, said circuit means being connected to all of said switch means, said indicator is freely movable on said board and is capable of being used to designate successive of said visually apparent indicia, said board has a concave shape and has an area whose depth is greater than the depth of the remainder of said board and said indicia representing a space is located in the area of the board having the greatest depth.
Claim 2
Dependent Claim
229 words
In a psychograph having a board, a plurality of visually apparent indicia located on said board and an indicator which is adapted to be moved relative to the surface of said board to designate successive of said indicia in order to express a communication in which the improvement comprises: said visually apparent indicia including indicia representing the letters of the alphabet, punctuation means and a space between letters, a switch means located on said board in association with each of said visually apparent indicia, actuating means for sequentially closing individual of said switch means when a sequence of said visually apparent indicia are designated by said indicator, said actuating means being located on said indicator so as to be movable therewith, circuit means for providing a signal capable of being used to obtain a record of said visually apparent indicia designated by said indicator in the sequence in which said visually apparent indicia are designated, said circuit means being connected to all of said switch means, said indicator is freely movable on said board and is capable of being used to designate successive of said visually apparent indicia, said board has a concave shape and has an area whose depth is greater than the depth of the remainder of said board and said indicia representing a space is located in the area of the board having the greatest depth.
Claim 3
Dependent Claim
22 words
A psychograph as claimed in claim 1 wherein: said area of greatest depth is located generally at the center of said board.
Claim 4
Dependent Claim
81 words
A psychograph as claimed in claim 1 including: audible means for providing a noise when a signal is provided by said circuit means, said audible means forming a part of said circuit means, visible means for providing a visible signal when a signal is provided by said circuit means said visible means being a part of said circuit means, and said indicator is a transparent disk through which said visually apparent indicia are visible when they are covered by said indicator.
