摘要:
A sheet conveying apparatus includes a discharge tray having a support surface supporting a sheet discharged by a discharge unit of a conveyor. A first stopper is provided on the support surface. A movable member is provided on the support surface between the discharge unit and the first stopper. The first stopper is changeable between a first position at which the first stopper protrudes from the support surface and a second position at which the first stopper is stored in the discharge tray. The movable member is changeable between a third position at which the movable member protrudes from the support surface and a fourth position located nearer to the support surface than the third position. The first stopper is changed from the first position to the second position in conjunction with a change of the movable member from the third position to the fourth position.

The present invention relates to a sheet stack thickness estimating device including a driving device, a first connecting rod, a second connecting rod, a pressing part and a sensor. The driving device provides a motive force to the sheet stack thickness estimating device so as to drive the first connecting rod moved horizontally for rotating the second connecting rod, so that the pressing part presses the sheets on the paper tray. By detecting if the signal generated by the sensor is blocked by the first connecting rod, the thickness estimating device can judge if the thickness of the sheets exceeds a predetermined value.

A medium correcting device includes: a first correction section that includes a first adjustment system to adjust mutually pressing forces between a first rod-like rotation body and a second rod-like rotation body, wherein a recording medium on which an image is formed passes between the first and second rod-like rotation bodies, and at least one of the first and second rod-like rotation bodies is driven to rotate at a driving speed according to the mutually pressing forces; and a second correction section that includes a second adjustment system to adjust mutually pressing forces between the circular surface of the first circularly-moving body and the outer circular surface of the belt member, wherein the recording medium passes between the first and second circularly-moving bodes, and at least one of the first and second circularly-moving bodes is driven to rotate at a driving speed according to the mutually pressing forces.

The sheets are supplied interfolded by two folding rollers, on a table on which they are piled up forming a stack. When the stack achieves a predetermined height a first plurality of separators and a second plurality of separators, arranged for all the length of the stack and from opposite sides are inserted into the stack to provide the disengagement of the stack already formed from a stack being formed, leaving between them of a wing of sheet hanging. The stack formed is then withdrawn quickly from the stack being formed by means of a table, which translates vertically, and is subject to a blow of air for stretching a possible last sheet. Then, the stack formed is left on a longitudinal conveyor belt located underneath. At the same time, a sheet stretching board moves under the stack of interfolded sheets, for all its length, for provisional support thereof and for stretching completely the wing hanging from the stack being formed with a portion of wing that exceeds sheet stretching board. Then the separators and withdraw laterally and an element moving from a direction opposite to the sheet stretching board, for example a blow of air, stretches the portion of the exceeding wing of sheet just before that the table comes back.

A feed roller unit comprises: a feed roller that abuts against a topmost sheet of a stack of sheets, and rotates to convey the topmost sheet in a conveyance direction, the feed roller being provided to be displaceable in a direction reverse to the conveyance direction while rolling on the topmost sheet; a driving force transmission unit that transmits a driving force generated by a driving source to the feed roller to rotate the feed roller; and an urging unit that provides an urging force to the feed roller in a direction to suppress the displacement of the feed roller.

A composite magazine for feeding to a filling or packaging machine pre-formed and flattened containers includes a main magazine suitably inclined in which the containers are piled up. The main magazine includes a long upper back portion which can be opened and closed downwardly. Below the main magazine there is provided an ancillary magazine which initially is in a substantially horizontal loading position in order to be easily supplied with a pile of containers on a bottom plane which leaves uncovered lateral portions of the bottom of the pile. When the upper back portion is emptied, the upper back portion is opened and the ancillary magazine is raised to insert the pile of containers in the main magazine. The upper back portion then closes to retain the pile, while the ancillary magazine returns in the low loading.
