A printing apparatus is capable of preventing a sheet discharged from a discharge unit from entering a feeding unit while guiding the sheet properly to a storage unit located below the feeding unit. The printing apparatus includes a storage unit configured to store a sheet discharged from a discharge unit and a guide unit configured to guide the sheet discharged from the discharge unit to the storage unit. The guide unit has a turning unit which prevents the sheet discharged from the discharge unit from entering a feeding unit and which turns when the sheet comes into contact with the turning unit.

A paper reversing apparatus includes a main conveyance path, a reversing path, first and second guiding plates and a hardware processor. The reversing path is disposed so as to form a predetermined angle with respect to the main conveyance path. Paper enters the reversing path from the main conveyance path and leaves the reversing path to the main conveyance path by being sent backward. When paper enters the reversing path, the processor moves the first guiding plate to a position for the paper to follow the first guiding plate and moves the second guiding plate to a position to avoid the paper. When paper leaves the reversing path, the processor moves the second guiding plate to a position for the paper to follow the second guiding plate and moves the first guiding plate to a position to avoid the paper.

The invention provides a sheet storage apparatus and a printing apparatus, which include simplified mechanisms for supporting a sheet and for guiding the sheet. A sheet storage device that can store a sheet discharged from a discharge port of a printing apparatus includes: multiple flappers provided below the discharge port and arranged in a width direction of the sheet, each flapper being rotatable between a first posture in which the sheet discharged from the discharge port is guided downward in a gravitational direction by using a first surface, and a second posture in which the sheet is supported by using a second surface being different from the first surface; and a connecting unit which connects the plurality of flappers to one another.

An object of the present invention is to provide a printing apparatus capable of preventing a sheet discharged from a discharge unit from entering a feeding unit while guiding the sheet properly to a storage unit located below the feeding unit. The printing apparatus includes a storage unit to store a sheet discharged from a discharge unit and a guide unit to guide the sheet discharged from the discharge unit to the storage unit. The guide unit has a turning unit which prevents the sheet discharged from the discharge unit from entering a feeding unit and which turns when the sheet comes into contact with the turning unit.

A sheet conveying apparatus includes a sheet stacking portion, a sheet feeding portion, a sheet conveyance path, an escape conveyance path branching off from the sheet conveyance path at a branch-off portion, a sheet discharge portion, a double-feed detector configured to detect double-feed of the sheet at a detection position, and a controller. A path length in the sheet conveyance path from the detection position to the branch-off portion is shorter than a length of a conveyable sheet. The controller switches a mode between a first mode of discharging the sheet for which the double-feed has been detected onto the sheet discharge portion via the escape conveyance path and a second mode of stopping the sheet for which the double-feed has been detected on the sheet conveyance path without discharging the sheet onto the sheet discharge portion in accordance with timing at which the double-feed detector detects the double-feed.

A device for providing improved measurements of logs. The device includes a feed path of the logs, configured to feed the logs in a direction orthogonal to the axis of the logs; and one or more pick-up members spaced from one another in a direction transverse to the feed path of the logs. The pick-up members are adapted to pick up individual logs from a pick-up position along the feed path; and transfer each log from the measuring position back to the feed path substantially in the position in which it was picked up.

An image forming apparatus includes an image forming section, a reverse transport portion that transports the recording medium in a reverse direction, which is opposite to a transport direction in which the recording medium is transported to the reverse transport portion from the image forming section, a first ejection portion to which the recording medium is ejected and that is disposed on a downstream side of a second transport path in the transport direction, the second transport path diverging from a first transport path along which the recording medium is transported from the image forming section to the reverse transport portion, and a reverse transport path along which the recording medium is transported from the reverse transport portion to the image forming section, the reverse transport path not overlapping a third transport path along which the recording medium is transported from the image forming section to the first ejection portion.

A controller, upon occurrence of a sheet jam in a downstream conveyor, discharges a sheet in an upstream conveyor from a discharge port by controlling an operation of a switchback roller depending on an operation status of the switchback roller at a time of the occurrence of the sheet jam and then stops sheet conveyance by a conveyor.
