Abstract
Abstract When a microfiche is automatically retrieved by a microfiche retrieval device, and the data of a target frame is input from the keyboard, the microfiche is conveyed to automatically retrieve the frame at the position relevant to the input data, and the largest frame is projected on a reader screen. The positional data for retrieving frames corresponding to the frame addresses other than that of the target frame and the fiche-mode data necessary for retrieving and outputting the imaged frames is stored in memory prior to retrieval of a frame. The stored data is read out so that the correct frame can be retrieved. Even if frames are not positionally aligned with the feeding direction of a particular microfiche or even if the reference frame or the maximum address frame is not exposed on a microfiche, frames can automatically be positioned at a high speed simply by designating a plurality arbitrary frames which are actually exposed with images.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
203 words
An automatic retrieval method in which a plurality of microfiches are sequentially and automatically retrieved, each of said microfiches having a plurality of frames which have been exposed with images and each of said plurality of frames having a different address, said method comprising the steps of: (a) selecting one microfiche from said plurality of microfiches; (b) selecting a frame of said selected microfiche; (c) calculating positioning data for aligning said selected frame based on the orientation of said selected frame on a retrieval device; (d) storing said calculated positioning data in a memory; (e) storing, in said memory, fiche-mode data defining at least one characteristic format of said selected microfiche; (f) performing steps (b)-(e) for each one of said plurality of frames on said selected microfiche; (g) performing steps (a)-(f) for each one of said plurality of microfiches; (h) reading out said calculated positioning data and said fiche-mode data from said memory when one of said plurality of microfiches is subsequently selected for retrieval; (i) positioning the subsequently selected frame in accordance with said read out data so that said subsequently selected frame is aligned on said retrieval device; and (j) repeating steps (h) and (i) for other frames to be retrieved.
Claim 2
Dependent Claim
203 words
An automatic retrieval method in which a plurality of microfiches are sequentially and automatically retrieved, each of said microfiches having a plurality of frames which have been exposed with images and each of said plurality of frames having a different address, said method comprising the steps of: (a) selecting one microfiche from said plurality of microfiches; (b) selecting a frame of said selected microfiche; (c) calculating positioning data for aligning said selected frame based on the orientation of said selected frame on a retrieval device; (d) storing said calculated positioning data in a memory; (e) storing, in said memory, fiche-mode data defining at least one characteristic format of said selected microfiche; (f) performing steps (b)-(e) for each one of said plurality of frames on said selected microfiche; (g) performing steps (a)-(f) for each one of said plurality of microfiches; (h) reading out said calculated positioning data and said fiche-mode data from said memory when one of said plurality of microfiches is subsequently selected for retrieval; (i) positioning the subsequently selected frame in accordance with said read out data so that said subsequently selected frame is aligned on said retrieval device; and (j) repeating steps (h) and (i) for other frames to be retrieved.
Claim 3
Dependent Claim
25 words
An automatic retrieval method as claimed in claim 1 wherein the number of said plurality of frames is in the range of two to three.
Claim 4
Dependent Claim
20 words
An automatic retrieval method as claimed in claim 1 wherein said memory is provided on a housing containing said microfiches.
Claim 5
Dependent Claim
17 words
An automatic retrieval method as claimed in claim 3, wherein said memory is provided on a cartridge.
Claim 6
Dependent Claim
16 words
An automatic retrieval method as claimed in claim 3, wherein said housing is a fiche jacket.
Claim 7
Dependent Claim
17 words
An automatic retrieval method as claimed in claim 1 wherein said memory is incorporated in a controller.
Claim 8
Dependent Claim
35 words
An automatic retrieval method as claimed in claim 1 wherein said memory is a memory device of a data retrieval system other than a data retrieval system in which said automatic retrieval method is implemented.
Claim 9
Dependent Claim
23 words
An automatic retrieval method as claimed in claim 1 wherein said stored calculated positioning data is stored on one sheet of said microfiche.
Claim 10
Dependent Claim
21 words
An automatic retrieval method as claimed in claim 1, wherein said memory is incorporated in a device subordinate to a controller.
Claim 11
Dependent Claim
28 words
An automatic retrieval method as claimed in claim 1, wherein the frames of said microfiche are not arranged in parallel with the moving directions of said retrieval device.
Claim 12
Dependent Claim
34 words
An automatic retrieval method as claimed in claim 1, wherein said plurality of frames does not include a reference frame or a maximum address frame in the row or column of said reference frame.
Claim 13
Dependent Claim
31 words
An automatic retrieval method as claimed in claim 2, wherein a reference frame or a maximum address frame in the row or column of said reference frame has not been exposed.
Claim 14
Dependent Claim
23 words
A method as claimed in claim 1 wherein the positioning data includes at least one of a reference pitch and a reference correction.
Claim 15
Dependent Claim
36 words
A method as claimed in claim 1 wherein the microfiche has a feeding direction relative to said retrieval device, and wherein said calculated positioning data determines alignment of the microfiche with respect to the feeding direction.
