Abstract
Abstract An image forming apparatus has a book binding mechanism for performing a book bind operation using front sheets of a plurality of sizes which can bind a bundle of sheet members recorded by said image forming apparatus, and have limitations on the numbers of recorded sheet members to be bound. The image forming apparatus further has output means for outputting sheet number data according to a bundle of sheet members; judge means for judging whether or not the sheet number data output from said output means is larger than a range of the limitation; detect means for, when the judged result from said judge means is affirmative, dividing the sheet number data, and detecting a divided sheet number value which falls within the range of the limitation; and control means for controlling to perform a book bind operation in units of the sheet numbers detected by said detect means.

Claim 2
Dependent Claim
143 words
An image forming apparatus having a book binding mechanism for performing a book bind operation using front sheets of a plurality of sizes which can bind a bundle of sheet members recorded by said image forming apparatus, and have limitations on the numbers of sheet members to be bound, comprising: output means for outputting sheet number data according to a bundle of sheet members; judge means for judging whether or not the sheet number data output from said output means is larger than a range of the limitation; detect means for, when the judged result from said judge means is affirmative, dividing the sheet number data, and detecting a divided sheet number value which falls within the range of the limitation; and control means for controlling to perform a book bind operation in units of the sheet numbers detected by said detect means.
Claim 3
Dependent Claim
38 words
An apparatus according to claim 1, wherein one of the plurality of sizes of the front sheets can be selected, and a number of divisions is determined in comparison with the plurality of sizes of the front sheets.
Claim 4
Dependent Claim
28 words
An apparatus according to claim 2, wherein said control means controls record means to perform image recording in units of the sheet numbers detected by said detect means.
Claim 5
Dependent Claim
29 words
An apparatus according to claim 2, wherein said control means controls distribution means to distribute the sheet materials in units of the sheet numbers detected by said detect means.
Claim 6
Dependent Claim
34 words
An apparatus according to claim 1, further comprising alarm means for, when the divided sheet number cannot fall within the range of the limitation, prohibiting a book bind treatment of said book binding mechanism.
Claim 7
Dependent Claim
32 words
An apparatus according to claim 3, wherein said recording means copies an original image on the sheet member, and said output means comprises count means for counting the number of original sheets.
Claim 8
Dependent Claim
110 words
An apparatus according to claim 1, further comprising: input means for inputting a size of a front sheet to be bound; a plurality of sheet member deposit means, for respectively depositing recording sheets having different sizes; record means for selectively picking up the sheet members having a size according to the size input from said input means, and recording images thereon; a plurality of front sheet deposit means for respectively depositing front sheets having different sizes; and book bind means for selectively picking up a front sheet having a size input from said input means, and binding the sheet members discharged from said record means with the selected front sheet.
Claim 9
Dependent Claim
89 words
An apparatus according to claim 7, wherein said record means comprises a first detection portion for detecting a size of the original, a first judgement portion for judging whether the detected size of the original is the same as a front sheet size input from said input means, and a magnification change recording portion for, when the judged result from said first judgement portion is negative, performing magnification change recording of the original on the sheet members in correspondence with the size of the sheet members to be recorded.
