Abstract

A retrieval apparatus of this invention includes retrieval processing sections constituted by semiconductor IC elements attached to each of the objects to be retrieved, and an operation section for supplying a retrieval condition to these retrieval processing sections. In each retrieval processing section, retrieval item information of an object to be retrieved to which the individual section is attached is stored in a storage section, a retrieval condition signaled from the operation section is received and analyzed, the analysis result is collated with the information stored in the storage section, and if a coincidence is detected, signaling is performed by light or sound. The retrieval condition may be constituted using logical product, logical sum and logical negation operators.

Claims

1. A hand-held book retrieval apparatus for use in a library, comprising:

retrieval request generating means including;

retrieval condition generating means for inputting a condition including at least logical product, logical sum, and logical negation for retrieving an object requested to be retrieved;

retrieval condition transmission means for transmitting the retrieval condition input from said retrieval condition generating means; and

retrieval request response means individually attached to a plurality of objects to be retrieved, and including;

retrieval condition reception means for receiving the retrieval condition including at least logical product, logical sum, and logical negation transmitted from the retrieval condition transmission means;

retrieval condition analyzing means, including means for performing at least any of the logical product, logical sum, and logical negation, for analyzing the retrieval condition received by said retrieval condition reception means;

identification information storage means for storing identification information inherent to the objects to be retrieved;

collating means for collating the analysis result from said analyzing means with the inherent identification information stored in said identification information stored means and outputting a coincidence signal when a coincidence is detected; and

signaling means for signaling, in response to the coincidence signal from said collation means, that the object requested to be retrieved is present.

2. An apparatus according to claim 1, wherein said retrieval request response means comprises an integrated circuit (IC) element and is attached to or incorporated in an object to be retrieved.
