Abstract
Abstract There is an information searching apparatus comprising: a photo disc device in which a plurality of image files are stored; a selecting circuit to select and read out one or a plurality of image files from among the image files stored in the photo disc device in accordance with a predetermined condition; a second memory device such as a semiconductor memory or a photo magnetic disc device to store the one or a plurality of image files read out by the selecting circuit; and a controller to control the readout of the image files from the photo disc device in accordance with the memory capacity of the second memory device and with the information quantity of the image files selected by the selecting circuit. In this apparatus, the search and readout of the image files are controlled by different controllers, so that a desired image file can be obtained for a short time.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
145 words
An information searching apparatus comprising: first memory means in which a plurality of image information files are stored; input means for inputting search information for searching for a desired image information file from among said plurality of image information files in said first memory means; search means for searching image information files to be read out from said first memory means, corresponding to said search information input by said input means; second memory means capable of storing a plurality of image information files searched and read out from said first memory means; transmitting means for transmitting a plurality of image information files searched by said search means in association with a common search information, from said first memory means to said second memory means; and means for selecting a desired image information file from among said image information files transmitted to said second memory means.
Claim 2
Dependent Claim
145 words
An information searching apparatus comprising: first memory means in which a plurality of image information files are stored; input means for inputting search information for searching for a desired image information file from among said plurality of image information files in said first memory means; search means for searching image information files to be read out from said first memory means, corresponding to said search information input by said input means; second memory means capable of storing a plurality of image information files searched and read out from said first memory means; transmitting means for transmitting a plurality of image information files searched by said search means in association with a common search information, from said first memory means to said second memory means; and means for selecting a desired image information file from among said image information files transmitted to said second memory means.
Claim 3
Dependent Claim
50 words
