Abstract
Abstract There is disclosed a microfilm reader-printer which permits to be set a number of pages of printing which exceeds a maximum number of pages of continuous printings of the printer body. The printer body outputs a completion signal to a device which set the number of pages of printing when printing is completed. The device sends a print request signal to the printer body every time when it receives a complete signal, until completion of printing for the set number of pages. The printer body completes the printing operation once for each maximum continuous number of pages of printing, but resumes printing if a print request signal is outputted successively.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
122 words
A microfilm reader/printer, comprising: a light source device for irradiating with light a microfilm to obtain projection light of the microfilm; image projection means for displaying an enlarged image of an image information recorded in the microfilm in accordance with the projection light; means for forming the image information recorded in the microfilm on a recording medium; a page searcher detachably provided to the microfilm reader/printer for moving the microfilm irradiated with the light; and means for directing said light source device, image protection means, image forming means, and page searcher so that when said page searcher is first attached to said microfilm reader/printer, the microfilm is automatically moved before said image forming means can form an image on the recording medium.
Claim 2
Dependent Claim
122 words
A microfilm reader/printer, comprising: a light source device for irradiating with light a microfilm to obtain projection light of the microfilm; image projection means for displaying an enlarged image of an image information recorded in the microfilm in accordance with the projection light; means for forming the image information recorded in the microfilm on a recording medium; a page searcher detachably provided to the microfilm reader/printer for moving the microfilm irradiated with the light; and means for directing said light source device, image protection means, image forming means, and page searcher so that when said page searcher is first attached to said microfilm reader/printer, the microfilm is automatically moved before said image forming means can form an image on the recording medium.
Claim 3
Dependent Claim
128 words
A microfilm reader/printer, comprising: a light source device for irradiating with light a bandlike microfilm to obtain projection light of the microfilm; image projection means for displaying an enlarged image of an image information recorded in the microfilm in accordance with the projection light; means for forming the image information recorded in the microfilm on a recording medium; a page searcher detachably provided to the microfilm reader/printer for feeding and rewinding the bandlike microfilm irradiated with the light; and means for directing said light source device, image projection means, image forming means, and page searcher so that when said page searcher is attached to the microfilm reader/printer, the bandlike microfilm is automatically fed and rewound before said image forming means can form an image on the recording medium.
Claim 4
Dependent Claim
128 words
A microfilm reader/printer, comprising: a light source device for irradiating with light a bandlike microfilm to obtain projection light of the microfilm; image projection means for displaying an enlarged image of an image information recorded in the microfilm in accordance with the projection light; means for forming the image information recorded in the microfilm on a recording medium; a page searcher detachably provided to the microfilm reader/printer for feeding and rewinding the bandlike microfilm irradiated with the light; and means for directing said light source device, image projection means, image forming means, and page searcher so that when said page searcher is attached to the microfilm reader/printer, the bandlike microfilm is automatically fed and rewound before said image forming means can form an image on the recording medium.
Claim 5
Dependent Claim
46 words
A microfilm reader/printer as in claim 1, wherein said page searcher further comprises print means for selectively activating said image forming means when the microfilm is not being moved, said print means prohibitting said image forming means from forming an image when said microfilm is moving.
Claim 6
Dependent Claim
52 words
A microfilm reader/printer as in claim 2, wherein said page searcher further comprises print means for selectively activating said image forming means when the bandlike microfilm is not being fed or rewound, said print means prohibiting said image forming means from forming an image when said microfilm is being fed or rewound.
Claim 7
Dependent Claim
57 words
A microfilm reader/printer as in claim 3, wherein said microfilm reader/printer further comprises second print means, not on said page searcher, for selectively activating said image forming means; and said page searcher further comprises means for prohibiting said second print means from activating said image forming means when said page searcher is attached to said microfilm reader/printer.
Claim 8
Dependent Claim
57 words
A microfilm reader/printer as in claim 4, wherein said microfilm reader/printer further comprises second print means, not on said page searcher, for selectively activating said image forming means; and said page searcher further comprises means for prohibiting said second print means from activating said image forming means when said page searcher is attached to said microfilm reader/printer.
Claim 9
Dependent Claim
54 words
A microfilm reader/printer as in claim 5, wherein said microfilm reader/printer further comprises means for detecting whether said page searcher is attached to the microfilm reader/printer, and said directing means directs said light source device, image projecting means, image forming means, and page searcher in accordance with a detecting signal from said detecting means.
Claim 10
Dependent Claim
54 words
A microfilm reader/printer as in claim 6, wherein said microfilm reader/printer further comprises means for detecting whether said page searcher ss attached to the microfilm reader/printer, and said directing means directs said light source device, image projection means, image forming means, and page searcher in accordance with a detecting signal from said detecting means.
Claim 11
Dependent Claim
159 words
A microfilm reader/printer comprising: a light source device for irradiating with light a microfilm to obtain projection light of the microfilm; image projection means displaying an enlarged image of an image information recorded in the microfilm in accordance with the projection light; means for forming the image information recorded in the microfilm on a recording medium; first print means for selectively activating said image forming means; a film handler for moving a microfilm by frame; and a page searcher detachably provided to the reader/printer including: means for directing said film handler to execute a frame search when said page searcher is attached to the microfilm reader/printer; means for prohibiting said first print means from activating said image forming means when said page searcher is attached to the microfilm reader/printer; and second print means for selectively activating said image forming means when said frame search directing means is not operating when said page searcher is attached to the microfilm reader/printer.
Claim 12
Dependent Claim
159 words
A microfilm reader/printer comprising: a light source device for irradiating with light a microfilm to obtain projection light of the microfilm; image projection means displaying an enlarged image of an image information recorded in the microfilm in accordance with the projection light; means for forming the image information recorded in the microfilm on a recording medium; first print means for selectively activating said image forming means; a film handler for moving a microfilm by frame; and a page searcher detachably provided to the reader/printer including: means for directing said film handler to execute a frame search when said page searcher is attached to the microfilm reader/printer; means for prohibiting said first print means from activating said image forming means when said page searcher is attached to the microfilm reader/printer; and second print means for selectively activating said image forming means when said frame search directing means is not operating when said page searcher is attached to the microfilm reader/printer.
