a first conveyance route of the sheet carrying the image; a sheet storing section which stores sheets on which no image is going to be formed; a second conveyance route to connect the sheet storing section and the first conveyance route; a notching section which forms notches on edges of the sheets; and a bookbinding section which accumulates the sheets to form a sheet bundle, and adhere a cover sheet to the sheet bundle to become a booklet, wherein the image forming section is placed upstream of a merging point of the first and second conveyance routes, with respect to a sheet conveyance direction of the first conveyance route, wherein the notching section is placed downstream of the merging point; and the bookbinding section is placed downstream of the notching section, with respect to the sheet conveyance direction. ## Claims ### Claim 1 A bookbinding system to produce booklets, comprising: an image forming section which forms an image on a sheet; a first conveyance route serving as a conveyance route of the sheet on which the image has been formed by the image forming section; a sheet storing section which stores sheets on which no image is to be formed by the image forming section; a second conveyance route serving as a sheet conveyance route to connect the sheet storing section and the first conveyance route; a notch forming section which forms notches on edges of conveyed sheets; and a bookbinding section which accumulates the conveyed sheets to form a sheet bundle, and adheres a cover sheet to the sheet bundle to form a booklet, wherein the image forming section is positioned upstream of a merging point of the first conveyance route and the second conveyance route, with respect to a sheet conveyance direction of the first conveyance route, wherein the notch forming section is positioned downstream of the merging point, with respect to the sheet conveyance direction; wherein a position of the conveyed sheet is changed under the notch forming section such that one of (i) a punching process to form round holes is selected and (ii) a notching process to form half round notches is selected, and wherein the bookbinding section is positioned downstream of the notch forming section, with respect to the sheet conveyance direction. ### Claim 2 (depends on 1) The bookbinding system of claim 1, further comprising a control section to control the bookbinding system, wherein when the bookbinding system produces a booklet in such a way that after the sheet carrying the image formed by the image forming section and the sheet stored in the sheet storing section are bundled as the sheet bundle, and the cover sheet is adhered to the sheet bundle by the bookbinding section, the control section controls the bookbinding system in such a way that the sheet carrying the image formed by the image forming section and the sheet stored in the sheet storing section are sequentially conveyed to the notch forming section based on page information of a job, and after the notches are formed on the edges of the sheets, the notched sheets are conveyed to the bookbinding section. ### Claim 3 (depends on 1) The bookbinding system of claim 1, further comprising a control section to control the bookbinding system, wherein when the bookbinding system produces a booklet in such a way that after the sheets carrying the image formed by the image forming section are bundled as the sheet bundle, and the cover sheet is adhered to the sheet bundle by the bookbinding section, the control section controls the bookbinding system in such a way that the sheets carrying the image formed by the image forming section are sequentially conveyed to the notch forming section, and after the notches are formed on the edges of the sheets, the notched sheets are conveyed to the bookbinding section. ### Claim 4 (depends on 2) The bookbinding system of claim 2, wherein when the bookbinding system produces a booklet in such a way that after the sheets carrying the image formed by the image forming section are bundled as the sheet bundle, and the cover sheet is adhered to the sheet bundle by the bookbinding section, the control section controls the bookbinding system in such a way that the sheets carrying the image formed by the image forming section are sequentially conveyed to the notch forming section, and after the notches are formed on the edges of the sheets, the notched sheets are conveyed to the bookbinding section. ### Claim 5 (depends on 1) The bookbinding system of claim 1, further comprising a control section to control the bookbinding system, wherein when the bookbinding system produces a booklet in such a way that after the sheets stored in the sheet storing section are bundled as the sheet bundle, and the cover sheet is adhered to the sheet bundle by the bookbinding section, the control section controls the bookbinding system in such a way that the sheets stored in the sheet storing section are sequentially conveyed to the notch forming section, and after the notches are formed on the edges of the sheets, the notched sheets are conveyed to the bookbinding section. ### Claim 6 (depends on 2) The bookbinding system of claim 2, wherein when the bookbinding system produces a booklet in such a way that after the sheets stored in the sheet storing section are bundled as the sheet bundle, and the cover sheet is adhered to the sheet bundle by the bookbinding section, the control section controls the bookbinding system in such a way that the sheets stored in the sheet storing section are sequentially conveyed to the notch forming section, and after the notches are formed on the edges of the sheets, the notched sheets are conveyed to the bookbinding section. ### Claim 7 (depends on 3) The bookbinding system of claim 3, wherein when the bookbinding system produces a booklet in such a way that after the sheets stored in the sheet storing section are bundled as the sheet bundle, and the cover sheet is adhered to the sheet bundle by the bookbinding section, the control section controls the bookbinding system in such a way that the sheets stored in the sheet storing section are sequentially conveyed to the notch forming section, and after the notches are formed on the edges of the sheets, the notched sheets are conveyed to the bookbinding section. ### Claim 8 (depends on 4) The bookbinding system of claim 4, wherein when the bookbinding system produces a booklet in such a way that after the sheets stored in the sheet storing section are bundled as the sheet bundle, and the cover sheet is adhered to the sheet bundle by the bookbinding section, the control section controls the bookbinding system in such a way that the sheets stored in the sheet storing section are sequentially conveyed to the notch forming section, and after the notches are formed on the edges of the sheets, the notched sheets are conveyed to the bookbinding section.
