摘要:
An image forming apparatus for forming an image on a recording material includes a cartridge accommodating a developer for developing an electrostatic latent image formed on a photosensitive member, a supporter detachably mounting the cartridge, and a preventor. The supporter moves between an inside position where the cartridge forms an image inside a main assembly of the apparatus and an outside position where the cartridge is mounted and demounted outside the main assembly. The preventor moves between a first position in which it prevents, when the cartridge is not mounted, movement of the supporter from the outside position to the inside position by contacting a portion thereof, and a second position, retracted from the first position, in which the it permits, when the cartridge is mounted, the movement of the supporter from the outside position to the inside position.

A toner cartridge includes a housing and a shutter inserted therein. The housing has a first partially cylindrical wall and a box-like portion that communicates with the first partially cylindrical wall. The shutter has a second partially cylindrical wall inserted inside the first partially cylindrical wall such that the second partially cylindrical wall is slidable on and concentric with an inner surface of the first partially cylindrical wall. The shutter has a supporting member that engages the housing to support the shutter such that the second partially cylindrical wall is in pressure contact with the first partially cylindrical wall. The supporting member may be in the shape of an arcuate member or ring that engages a part of the box-like portion so that the shutter is rotatably supported in the housing by the part and the first partially cylindrical wall. The housing has a projection or rib that inwardly projects toward the first partially cylindrical wall. The projection abuts the arcuate member so that the shutter is rotatably supported in the housing by the arcuate member and the first partially cylindrical wall.

Van A and Van B vancomycin resistant enterococci detection media as well as a method of selectively detecting Van A and Van B vancomycin resistant enterococci clinically important in vancomycin resistant enterococci from testing microorganisms or specimens using the media. The media for selectively detecting Van A and Van B VRE from testing microorganisms and specimens are media where enterococci can grow where vancomycin, D-cycloserine and D-lactate are added. Preferably 32-256 μg/ml of vancomycin, 1-64 μg/ml of D-cycloserine, and 0.025-0.8 mol/l of sodium lactate are added to culture medium where enterococci can grow.

A lower punch is arranged to be inserted into a cavity of a die from a lower side of the die. A upper punch is arranged to be inserted into the cavity from an upper side of the die to compact the powder filled in the cavity, in cooperation with the lower punch. A feeder supplies the powder into the cavity. A first cam driving system has a first cam for vertically moving the die relative to the lower punch. A second cam driving system has a second cam for vertically moving the upper punch. A third cam driving system has a third cam for moving the feeder forward or backward relative to the cavity. A contact member is connected to the first cam driving system. A stopper is located above or below the contact member and regulates relative vertical movement of the die with respect to the lower punch, in cooperation with the contact member. A fourth cam driving system has a fourth cam for vertically moving the stopper. The first cam, the second cam, the third cam, and the fourth cam are rotated in synchronism.
