Abstract

Abstract A recorder, as for photographing original documents on microfiche, the documents selectively having information on one or both sides, which information is to be successively recorded at high speed. After initial transport by a feed belt, a first vacuum-retaining belt having document-present actuated controls moves the document to a photographing position. Thereafter this belt is reversed in direction and the document is taken from the first belt to a second vacuum-retaining belt by pneumatic force. Adhering to the second belt, the document is rotated 180°, side for side, and discharged again to the first belt. A second forward motion of the first belt returns the document to the photographing station, second side up. Further forward motion discharges the document. The images upon the fiche have the same orientation for both sides of the document for easy reading. Typically, one-sided documents are turned over, but are not photographed on the second (blank) side. An electronic logic system of the state counter type correlates the several steps of document handling.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 101 words
The method of moving a document for stationarily exhibiting both sides thereof, which includes, in order, the steps of; a. planarly translating said document while flat forward over a path to an exhibiting position (67), and stopping it, b. planarly translating said document while flat backward from said exhibiting position over substantially the same said path, c. curvilinearly turning said document over while it is completing the backward translation, d. returning said document to said path at an inclination thereto, and e. again planarly translating said document while flat forward over said path to the exhibiting position, and again stopping it.
Claim 2
Independent Claim 101 words
The method of moving a document for stationarily exhibiting both sides thereof, which includes, in order, the steps of; a. planarly translating said document while flat forward over a path to an exhibiting position (67), and stopping it, b. planarly translating said document while flat backward from said exhibiting position over substantially the same said path, c. curvilinearly turning said document over while it is completing the backward translation, d. returning said document to said path at an inclination thereto, and e. again planarly translating said document while flat forward over said path to the exhibiting position, and again stopping it.
Claim 3
Dependent Claim 28 words
The method of claim 1, which includes the additional step of; a. subsequently planarly translating said document while flat farther forward to terminate the motion of said document.
Claim 4
Independent Claim 102 words
The method of moving a document for stationarily exhibiting one side thereof, which includes, in order, the steps of; a. planarly translating said document while flat forward over a path to an exhibiting position (67), and stopping it, b. planarly translating said document while flat backward from said exhibiting position over substantially the same said path, c. curvilinearly turning said document over while it is completing the backward translation, d. returning said document to said path at an inclination thereto, and e. again planarly translating the document forward while flat, to and farther coplanarly forward than the location of said exhibiting position.
Claim 5
Independent Claim 102 words
The method of moving a document for stationarily exhibiting one side thereof, which includes, in order, the steps of; a. planarly translating said document while flat forward over a path to an exhibiting position (67), and stopping it, b. planarly translating said document while flat backward from said exhibiting position over substantially the same said path, c. curvilinearly turning said document over while it is completing the backward translation, d. returning said document to said path at an inclination thereto, and e. again planarly translating the document forward while flat, to and farther coplanarly forward than the location of said exhibiting position.
