The conveyance unit conveys paper. The first storage unit stores a width of standard paper. The width of the standard paper is a length in a direction crossing a conveyance direction of the paper conveyed by the conveyance unit. The second storage unit stores a user-registered paper width which is different from the width of the standard paper. The user-registered paper width is input by a user. The measurement unit measures a width of the paper. The determination unit determines, based on the measured width and the paper widths stored in the first storage unit and the second storage unit, a width to serve as the measured width. ## Claims ### Claim 1 A conveyance apparatus comprising: a conveyance unit configured to convey paper; a first storage unit configured to store a width of standard paper, wherein the width of the standard paper is a length in a direction crossing a conveyance direction of the paper conveyed by the conveyance unit; a second storage unit configured to store a user-registered paper width which is different from the width of the standard paper, wherein the user-registered paper width is input by a user; a measurement unit configured to measure a width of the paper; and a determination unit configured to determine, based on the measured width and the paper widths stored in the first storage unit and the second storage unit, a width to serve as the measured width. ### Claim 2 (depends on 1) The conveyance apparatus according to claim 1, wherein, if the measured width falls within a predetermined range of the stored standard paper width or the stored user-registered paper width, the determination unit determines the paper width stored in the first storage unit or the paper width stored in the second storage unit as the width to serve as the width of the paper measured by the measurement unit. ### Claim 3 (depends on 2) The conveyance apparatus according to claim 2, wherein, if the measured width is determined to be neither of the stored standard paper width and the stored user-registered paper width, the determination unit determines the measured width as the width to serve as the width of the paper measured by the measurement unit. ### Claim 4 (depends on 2) The conveyance apparatus according to claim 2, wherein the predetermined range can be set differently depending on paper widths. ### Claim 5 (depends on 2) The conveyance apparatus according to claim 2, wherein the first storage unit is configured to store a priority for the determination with respect to paper widths of which predetermined ranges overlap among a plurality of the paper widths stored in the first storage unit, and wherein, if the measured width is determined to fall within the overlap between the predetermined ranges of the paper widths stored in the first storage unit, the determination unit determines the width to serve as the measured width based on the stored priority. ### Claim 6 (depends on 1) The conveyance apparatus according to claim 1, wherein the second storage unit is configured to store a plurality of the user-registered paper widths. ### Claim 7 (depends on 1) The conveyance apparatus according to claim 1, wherein the determination unit is configured to give priority to determining the user-registered paper width as the width to serve as the measured width over determining the width of the standard paper as the width to serve as the measured width. ### Claim 8 (depends on 1) The conveyance apparatus according to claim 1, further comprising a recording unit configured to record an image on the paper conveyed to a recording position by the conveyance unit, wherein the determination unit is configured to determine the width of the paper as a width to be used for control in the recording of the image by the recording unit on the paper measured by the measurement unit. ### Claim 9 (depends on 8) The conveyance apparatus according to claim 8, further comprising a generation unit configured to generate image data for the recording of the image by the recording unit based on the determined width to be used for the control in the recording of the image. ### Claim 10 (depends on 1) The conveyance apparatus according to claim 1, wherein the user-registered paper width stored in the second storage unit is deletable. ### Claim 11 (depends on 1) The conveyance apparatus according to claim 1, further comprising an acceptance unit configured to accept an input for registering the user-registered paper width in the second storage unit. ### Claim 12 (depends on 11) The conveyance apparatus according to claim 11, wherein the acceptance unit is configured to accept the input for registering the user-registered paper width while the conveyance unit is not conveying the paper. ### Claim 13 (depends on 11) The conveyance apparatus according to claim 11, further comprising a recording unit configured to record an image on the paper conveyed to a recording position by the conveyance unit, wherein the acceptance unit is configured to accept the input for registering the user-registered paper width while the conveyance unit is not conveying the paper and while the recording unit is not recording the image on the paper. ### Claim 14 A method for a conveyance apparatus, the method comprising: conveying paper; storing, as a first storage, a width of standard paper, wherein the width of the standard paper is a length in a direction crossing a conveyance direction of the conveyed paper; storing, as a second storage, a user-registered paper width which is different from the width of the standard paper, wherein the user-registered paper width is input by a user; measuring a width of the paper; and determining, based on the measured width and the paper widths stored in the first storage and the second storage, a width to serve as the measured width. ### Claim 15 (depends on 14) The method according to claim 14, further comprising using the determined width to control a recording unit to record an image on the paper. ### Claim 16 A non-transitory computer-readable storage medium storing a program to cause a computer to perform a method for a conveyance apparatus, the method comprising: conveying paper; storing, as a first storage, a width of standard paper, wherein the width of the standard paper is a length in a direction crossing a conveyance direction of the conveyed paper; storing, as a second storage, a user-registered paper width which is different from the width of the standard paper, wherein the user-registered paper width is input by a user; measuring a width of the paper; and determining, based on the measured width and the paper widths stored in the first storage and the second storage, a width to serve as the measured width.
