Abstract
Official abstract text for this publication.
A sheet transport device includes a processor configured to adjust movement of a transport unit that transports a sheet on the basis of a transport load of the sheet.
First claim
Opening claim text (preview).
What is claimed is: 1 . A sheet transport device comprising a processor configured to adjust movement of a transport unit that transports a sheet on a basis of a transport load of the sheet. 2 . The sheet transport device according to claim 1 , wherein the processor obtains the transport load from size information indicative of a size of the sheet and basis weight information indicative of a weight of the sheet per unit area. 3 . The sheet transport device according to claim 1 , wherein the transport unit transports the sheet while sucking the sheet. 4 . The sheet transport device according to claim 2 , wherein the transport unit transports the sheet while sucking the sheet. 5 . The sheet transport device according to claim 3 , wherein in a case where the transport load is larger than a predetermined value, the processor adjusts the movement by making a transport speed at which the transport unit is moved in a transport direction lower than the transport speed set in a case where the transport load is equal to or smaller than the predetermined value. 6 . The sheet transport device according to claim 4 , wherein in a case where the transport load is larger than a predetermined value, the processor adjusts the movement by making a transport speed at which the transport unit is moved in a transport direction lower than the transport speed set in a case where the transport load is equal to or smaller than the predetermined value. 7 . The sheet transport device according to claim 3 , wherein in a case where the transport load is larger than a predetermined value, the processor adjusts the movement by making a transport acceleration at which the transport unit is moved in a transport direction lower than the transport acceleration set in a case where the transport load is equal to or smaller than the predetermined value. 8 . The sheet transport device according to claim 4 , wherein in a case where the transport load is larger than a predetermined value, the processor adjusts the movement by making a transport acceleration at which the transport unit is moved in a transport direction lower than the transport acceleration set in a case where the transport load is equal to or smaller than the predetermined value. 9 . The sheet transport device according to claim 5 , wherein the processor makes a return speed at which the transport unit is returned in a direction reverse to the transport direction higher than the transport speed at which the transport unit is moved in the transport direction. 10 . The sheet transport device according to claim 6 , wherein the processor makes a return speed at which the transport unit is returned in a direction reverse to the transport direction higher than the transport speed at which the transport unit is moved in the transport direction. 11 . The sheet transport device according to claim 9 , wherein the processor makes the return speed higher than the transport speed set in a case where the transport load is equal to or smaller than the predetermined value. 12 . The sheet transport device according to claim 10 , wherein the processor makes the return speed higher than the transport speed set in a case where the transport load is equal to or smaller than the predetermined value. 13 . The sheet transport device according to claim 7 , wherein the processor makes a return acceleration at which the transport unit is returned in a direction reverse to the transport direction higher than the transport acceleration at which the transport unit is moved in the transport direction. 14 . The sheet transport device according to claim 8 , wherein the processor makes a return acceleration at which the transport unit is returned in a direction reverse to the transport direction higher than the transport acceleration at which the transport unit is moved in the transport direction. 15 . The sheet transport device according to claim 13 , wherein the processor makes the return acceleration higher than the transport acceleration set in a case where the transport load is equal to or smaller than the predetermined value. 16 . The sheet transport device according to claim 14 , wherein the processor makes the return acceleration higher than the transport acceleration set in a case where the transport load is equal to or smaller than the predetermined value. 17 . A non-transitory computer readable medium storing a program causing a computer to execute a process comprising adjusting movement, in a transport direction, of a transport unit that transports a sheet on a basis of a transport load of the sheet. 18 . A sheet transport device comprising processing means for adjusting movement of a transport unit that transports a sheet on a basis of a transport load of the sheet.
