Abstract

Measured data storage apparatus for digital indication type article measuring apparatus used to measure more than one type of article is connected to a main body of the measuring apparatus so as to be operatively transportable with the measuring apparatus for measuring the articles and removable from the measuring apparatus for reading of the stored contents of the storage apparatus by an external computer. The storage apparatus comprises data switch apparatus for controlling input of measured values to the storage apparatus, and data identifying apparatus operative with the data switch apparatus for storing in the storage apparatus identifying data associated with each inputted measured value signifying at least the article to which each measured value corresponds.

Claims

1. Digital indication type article measuring appartus comprising:

an encoder connected to a measuring element, for detecting a displacement of said measuring element;

a counter for counting output signals from said encoder; and

a digital indicator for indicating a value counted by said counter as a measured value and for producing a measured value output;

wherein the improvement comprises;

computer readable portable data storage means responsive to said measured value output for directly storing measured values relating to a plurality of measured articles, said data storage means being connected to a main body of said measuring apparatus so as to be operable and transporable with said measuring apparatus for measuring the articles and separable from said measuring apparatus for reading of the stored contents of said storage means by an external computer without interfering with the operation of said digital indicator;

data switch means for controlling input of said measured values to said data storage means; and

data identifying means responsive to said data switch means for automatically generating and storing in said data storage means predetermined identifying data associated with each inputted measured value signifying the article to which each measured value corresponds.

2. Digital indication type article measuring apparatus as set forth in claim 1 wherein said data storage means is releaseably connected to said measuring apparatus main body by an electric cable.

3. Digital indication type article measuring appartus as set forth in claim 1 wherein said data storage means is releasably mounted on said measuring apparatus main body.

4. Digital indication type article measuring apparatus as set forth in claim 1 wherein said digital indicator indicates the identifying data corresponding to the measured value being indicated.

5. Measured data storage apparatus for digital indication type article measuring apparatus used to measure more than one type of article;

said storage apparatus comprising;

input means releasably connected to a measured value output of the measuring apparatus and data switch means connected to said input means for controlling the input of measured values from the measuring apparatus to said storage apparatus;

first control means for generating a control value specifying the number of different types of articles for which measured values are to be stored;

second control means for generating a control value for each different article type to be measured specifying the number of articles of that type for which measured values are to be stored;

third control means for generating a control value for each different article type specifying the number of measuring points at which articles of that type are to be measured;

data identifying means responsive to said data switch means and said control values generated by said first, second and third control means for automatically generating identifying data associated with each inputted measured value signifying the article type, the article number, and the measuring point to which the measured value corresponds;

storage memory means for successively storing the inputted measured values and associated identifying data; and

output means responsive to an external computer for outputting each stored measured value in conjunction with the identifying data associated therewith.

6. Measured data storage apparatus as set forth in claim 5 wherein said data switch means includes first switch means mounted on said storage apparatus and second switch means mounted on the measuring apparatus.

7. Measured data storage apparatus as set forth in claim 5 wherein said storage apparatus is adapted to be carried by the operator while the measuring apparatus is being used.
