Abstract: Pressures of left and right clutch pistons (55, 63) applied to left and right disk portions (42b, 42d) of a common clutch outer (42) of left and right clutches (29, 30) distributing drive force of an input shaft (20) to left and right output shafts (23, 24) are, finally, transmitted to and supported by a side housing (12) through a boss portion (42a) of the clutch outer (42) and a thrust bearing (53, 52, 48; 41, 27). Accordingly, the left and right clutches (29, 30) can be engaged with no problem. Even when the pressures of the clutch pistons (55, 63) deform the left and right disk portions (42b, 42d) of the clutch outer (42), the gap (?) formed therebetween prevents the transmission of the pressure of one of the clutches (29, 30) to the other clutch (29, 30). Accordingly, the interference between the operations of the left and right clutches (29, 30) is prevented.

Abstract: When an instruction for combine setting is accepted, a reduction ratio of an original image is set as a first reduction ratio based on an orientation of the original image and an orientation of output paper. When an instruction to change the reduction ratio for the previewed original image is accepted, if a reduction ratio after the change (a second reduction ratio) falls within a prescribed range from the first reduction ratio, the first reduction ratio is set as a reduction ratio of the original image for arranging onto a sheet of output paper in combination.

Abstract: It is determined whether the service mode is turned off. When it is determined that the service mode is turned off, the remote access job history is checked. A CPU then determines whether there is an unexecuted job. When determining that there is an unexecuted job, the CPU inquires of the PC providing an instruction to execute the job whether to re-execute the job. The CPU then determines whether an instruction to re-execute the unexecuted job has been accepted. When determining that an instruction to re-execute the unexecuted job has been accepted, the CPU re-executes the unexecuted job.

Abstract: Under a contention between a copy job and a print job, it is possible that a general user misunderstands that the payment he has made for the copy job is mistakenly used on the print job requested by another user. One solution to avoid such undesirable possibility is to display information indicating that the billing process is correctly done. Yet, the general user may fail to notice the display. In view of this, a billing and printing system prevents occurrence of job contention as long as the balance of payment made by a general user remains. An MFP included in the system does not accept any print job if a balance of received payment remains, and does not accept any payment if there is a queued print job.

Abstract: An image processing apparatus includes a display for displaying operational information for executing image processing, an operation unit for giving an input instruction in association with a display region appearing on the display, and a controller for controlling the display in accordance with the input instruction on the operation unit. The controller is configured to determine whether an input instruction of a flick operation is given through the operation unit in association with a prescribed display region appearing on the display. If it is determined that the input instruction of the flick operation is given, the controller is configured to enlarge a range of the prescribed display region in which the input instruction is allowed, and to display the enlarged display region on the display.
