A sheet storage device includes a sheet storage to stack and store sheets conveyed to the sheet storage in a conveyance direction. The sheet storage includes: a first sheet contact surface at a downstream end of the sheet storage in the conveyance direction; a second sheet contact surface at one end of the sheet storage in an orthogonal direction orthogonal to each of the conveyance direction and the gravity direction; a first inclined portion having an upper end at a downstream side and a lower end at an upstream side in the conveyance direction and having the first sheet contact surface tilted downward in a gravity direction from the upper end to the lower end; and a second inclined portion tilted downward in the gravity direction toward the second sheet contact surface in the orthogonal direction.

A recording device includes a recording section, a discharge section 38 that discharges the medium, a pivot shaft 39 that pivots the discharge section 38, a contact member 48 that configure to swing around the pivot shaft 39 and to contact the medium to be discharged, and a detection section 45 that detects a displacement of the contact member 48, wherein the contact member 48 is provided with a swing restriction section 58 that restricts a range of swinging by engaging the protrusion 57 on the pivot shaft 39, a position of the protrusion 57 that engages with the swing restriction section 58 changes according to pivot the pivot shaft 39, and a position at which the contact member 48 is swingable changes between when the discharge section 38 is positioned at a nip position P1 and when the discharge section 38 is positioned at a non-nip position P2.

A sheet storage apparatus and a printing apparatus 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.

The present invention provides a long separator roll. A method according to the present invention for producing a battery separator roll includes a connecting step of connecting two or more separators (12b and 12c) to each other along a lengthwise direction so that the battery separator roll is produced.

A medium placement device is configured to stack a plurality of sheets of a medium discharged from a discharge unit of a processing device. The medium placement device includes a plurality of support units being provided in a width direction intersecting with a discharge direction of the medium discharged from the discharge unit, and being configured to support the medium at a support surface from below in a gravitational direction. A first support unit and a second support unit are provided in an alternating manner in the width direction, the second support unit being arranged at a position lower than the first support unit in the gravitational direction when viewed in the width direction. The first support unit is provided with a bridging member configured to couple a lower side of the discharge unit in the gravitational direction and the support surface of the first support unit.

Personnel saving of a process from a printer to a sheet processing machine is achieved. A general printing management device is connected to be communicable with a conveyance management device that manages a plurality of automatic guided vehicles each conveying a stacker in which paper ejected from a printer is stackable. The general printing management device generates conveyance instruction information for conveying a stacker in which paper ejected from the printer is stacked from a sheet receiving position of the printer to a sheet supply position of a next processing machine, based on job information in which a manufacturing process procedure for manufacturing a printed product is registered, and transmits the conveyance instruction information to the conveyance management device.
