Photograph multiplying factor automatic-counting scale
First Claim
1. In an automatic photograph measurement, multiplying and counting apparatus for providing digital measurements of distances appearing in a photograph, said apparatus having:
- (1) an elongated straight piece (1) for placing on a photograph along a distance to be measured;
(2) an elongated guide scale (6) coupled to and disposed alongside said piece (1);
(3) detecting scale head means (7) disposed for slidable engagement along said scale (6) including a control button (10a) thereon;
(4) a transparent plate (8) projecting from said head means (7) with a reference line (9) thereon to be placed at a reference point on a photograph to be measured;
(5) a pulse generator coupled to said piece (1) and said button (10a), with gating circuitry providing pulse signals per unit length in proportion to the movement of said head means (7);
(6) a binary coded decimal counter (3) including conversion in said apparatus coupled to said pulse generator, receiving and counting said pulse signals and converting them into binary coded decimals;
(7) mathematical circuit means including interface circuitry coupled to the output of said counter (3);
(8) display means (18) coupled to said mathematical circuit means;
the improvement therein comprising;
(8) first and second pulleys (21,
22) at one and the other end of said piece and an endless wire between said pulleys;
(9) a rotary encoder pulse generator acting as said pulse generator, said rotary encoder being mounted at said one end of said piece (1) coupled to and responsive to said first pulley; and
,(10) said head means being coupled to said wire so that the movement of said head means along said scale turns said rotary encoder to generate pulses.

Abstract
A photograph multiplying factor automatic-counting scale including a scale head linearly movable, a pulse generator generating pulse signal per unit length in proportion to movement of said scale head, a BCD counter through which said pulse signal from said pulse generator is converted into BCD code and counted, an interface circuit into which output value from said BCD counter is fed through a BCD decimal converter, and an arithmetic circuit into which output value from said interface circuit is fed through output of a program starting button, so that a length measuring apparatus including said scale head may obtain original dimensions as divisor, whereby said arithmetic circuit divides finished dimensions by said original dimensions and the quotient obtained by said arithmetic circuit is displayed or printed out.
