At least one mobile part included in a plate separator is configured movable between a first position and a second position, which is different from the first position. At least one biasing portion biases the at least one mobile part toward the first position. The at least one mobile part includes a contact portion that comes into contact with the top plate when a plate holder lifts the top plate upward. The at least one mobile part is configured to be moved toward the second position as being pushed by the top plate when the top plate in contact with the at least one contact portion is moved further upward, thereby allowing an upward movement of the top plate.

The present invention provides, in various embodiments, a batch feeder and a method for stocking and gravity conveying of piece goods made of flat material. A feeder pit comprises an upper opening for inputting the piece goods in batches, a lower opening for extraction of the piece goods, and at least two lateral pit delimitations, which are located opposite to one another, for guiding of the piece goods. As carrying structures for supporting the piece goods on one side, that are arranged on top of each other as floors and that protrude into the feeder pit, are formed on at least one of the pit delimitations, the piece goods can be retained alternatingly on the carrying structures in an easy way and move up respectively for each floor.

An apparatus for printing on one or both sides of flat objects. The apparatus includes a loop-shaped conveying path for the flat objects; a feed conveyor configured to feed the objects to be printed into a first section of the conveying path; a printer configured to print the objects one at a time; a first discharge conveyor configured to discharge the objects to be printed one at a time downstream of the printer from the first section towards a second section; a first collector configured to collect the objects downstream of the first discharge conveyor at the second section discharged from the first discharge conveyor in a stack; a stack conveyor configured to convey a (partial) stack of the objects along the second section; and a second collector configured to receive at least one (partial) stack and feed the objects upstream to the printer into the first section.

A dispenser (200) includes a supply structure (202) and a biasing structure (206). The supply structure holds mailers (204). A mailer from the mailers includes a first wall and a second wall. The first and second walls are closed at a first side of the mailer, closed at a second side of the mailer, and closed at a closed end of the mailer. The first and second walls are not closed at an open end of the mailer. The mailer is arranged to be dispensed from the supply structure (202). The biasing structure (206) is arranged to engage the mailer as the mailer is dispensed from the supply structure (202). The biasing structure (206) has narrowing surfaces configured to contact the sides of the mailer as the mailer is dispensed. The narrowing surfaces of the biasing structure (206) are arranged to narrow the open end of the mailer thereby causing the open end to be biased open.

A cover slip dispenser apparatus for storing and dispensing microscope cover slides includes a dispenser body having a square top aperture extending through to a dispenser inside. The dispenser inside is configured to store a plurality of cover slips. A bottom frame has a plurality of spring-loaded ball detents to prevent the plurality of cover slips from passing through unless forced. A plunger is coupled within the dispenser inside and is configured to contact a topmost slip of the plurality of cover slips. A spring is coupled within the dispenser inside and is configured to apply pressure on the plunger to arrange the plurality of cover slips against the plurality of ball detents. A lever is coupled to the dispenser body. A lever bottom of the lever is coupled to the spring. The lever is configured to dispense one cover slip of the plurality of cover slips when depressed.

A sheet conveyance apparatus include a first conveyance unit, a second conveyance unit including a cover and configured to be movable between a first position where a sheet conveyed from the first conveyance unit can be conveyed to a sheet conveyance path and a second position separated from the first position, and a retaining portion configured to retain the cover at an open position and to retain the second conveyance unit at the second position through the cover retained at the open position in a case where the cover is positioned at the open position in a condition in which the second conveyance unit is positioned at the second position.

The invention relates to a device for receiving, transporting, and dispensing film bags, comprising a film bag magazine with multiple parallel magazine shafts and two circulating conveyor belt devices which can be driven independently of each other and which comprise film bag receiving areas arranged thereon, said conveyor belt devices circulating about two common axes. The two axes are designed to be drivable independently of each other, and each axis drives one of the two conveyor belt devices. The invention further relates to a method for receiving, transporting, and dispensing film bags by means of the device for receiving, transporting, and dispensing film bags.
