An adjustable backdrop support system kit includes at least two interlocking bars, two adjustable tripod stands and a backdrop, during usage, the at least two interlocking bars are interlocked with each other to form a supporting crossbar having two ends which are respectively on tops of the two adjustable tripod stands to configure a support system for supporting a backdrop at a predetermined height, wherein the backdrop is adapted for being supported by the supporting crossbar and being extending downward to provide a photographing background environment.

Provided is a powder container having a new structure capable of stable discharge and transport of a powder contained in a container by enabling the powder to be reliably discharged to the outside of the package while preventing the powder from spilling and flying out of the container. The powder container has a container body (138) for transporting powder contained therein from a first end side (138a) to a second end side (138b) thereof by self-rotating; a nozzle receiver (139) having a nozzle receiving hole (insertion section) (139a) arranged inside the second end side of the container body and configured to allow a transport nozzle (162) having a powder receiving inlet (170) to be inserted therein, and a supply port 139b arranged in at least a part of the nozzle receiver (139) and configured to supply the powder in the container body (138) to the powder receiving inlet (170): and a shutter (140) supported by the nozzle receiver 139 and configured to open and close the nozzle receiving hole (insertion section) 139a by sliding in response to insertion of the transport nozzle 162 into the nozzle receiver (139).

An electrophotographic image forming apparatus has a developing roller, wherein a glossiness of a surface of the developing roller is in a range of about 4 to about 15, the developing roller includes a plurality of protruding beads, a number average distance (Rsm) between the protruding beads is in a range of about 200 m to about 400 m, a supplying roller includes a plurality of foam cells, a number average size of the foam cells is in a range of about 300 m to about 500 m, and the developing roller is arranged to rotate at a rotation linear velocity that is about 120% to about 150% of a rotation linear velocity of a photoreceptor.

A method for controlling a robotic apparatus to produce desirable photographic results. The method includes, with a motor controller, first operating a robotics assembly to animate the robotic apparatus and, then, detecting an upcoming image capture. The method further includes, with the motor controller in response to the detecting of the upcoming image capture, second operating the robotics assembly to pose the robotic apparatus for the upcoming image capture. In some embodiments, the detecting includes a sensor mounted on the robotic apparatus sensing a pre-flash of light from a red-eye effect reduction mechanism of a camera. In other cases, the detecting includes a sensor mounted on the robotics apparatus sensing a range finder signal from a range finder of a camera. The posing may include opening eyes, moving a mouth into a smile, or otherwise striking a pose that is held temporarily to facilitate image capture with a camera.

A backdrop-and-lighting hanging kit is a kit that allows the user to setup different photography backdrops and accessories in a single support assembly to maintain a clean setup and work space. The kit generally includes several elongated supports and accessory mounts. The elongated supports are existing support devices that help construct the desired support assembly. The accessory mounts connect the corresponding elongated supports together to construct the support assembly. The accessory mounts also facilitate the mounting of photography lights and accessories to the support assembly to maintain a clean and organized work space. Each of the accessory mounts includes a mount body, an accessory-attachment mechanism, and a support-attachment mechanism. The support-attachment mechanism allows the removable attachment of the mount body to an elongated support. The mount body supports the accessory-attachment mechanism and the mounted accessory. Further, the accessory-attachment mechanism allows the secure mounting of an accessory to the mount body.

A projection device includes a camera that captures an image of a real space in which an object is disposed and a projector that projects an image indicated by video data generated based on the captured image by the camera onto an image capturing region of the camera in the real space. The video data is, for example, a pointing image such as an arrow or a finger point pointing to an object disposed in the real space. The projection device detects the object by image recognition from the captured image and generates video data for displaying a pointing image pointing to the object at a position superimposed on or adjacent to the object. When the image indicated by the video data generated is projected from the projector, the pointing image is displayed at a position superimposed on or adjacent to the object in the real space.

A developing cartridge has a casing for accommodating developer and having a first side and a second side opposite each other in a first direction and a third side and a fourth side opposite each other in a second direction. The developing cartridge also has a rotatable input gear on the first side, for receiving a driving force; a developing roller on the third side; a chip with an electrical contact surface on the first side; and a first protrusion on the first side and having a first force receiving surface. The electrical contact surface is fixed relative to the casing. When the developing cartridge is mounted in an image forming device, the first force receiving surface may receive a force (e.g., by abutting a door cover of the image forming device), thereby moving the developing cartridge against gravity.
