A lens apparatus is mountable to a camera body. The camera body has multiple electric contacts. Of these multiple electric contacts, when mounting the lens apparatus to the camera body, electric contacts used for second communication or third communication come into contact with an electric contact provided to the lens apparatus before electric contacts used for first communication, when mounting the lens apparatus to the camera body.

A stamping tool is provided including a base and a cover. The cover is removably affixed to the base through a hinging assembly. The base can include a first base hinge and a second base hinge substantially perpendicular to the first base hinge. The base hinges can be one or more hinge sections. The hinge sections can include a first wall and a second wall that can be biased to define a cavity that is accessible through a channel between the first wall and the second wall. Hinge sections can be separated by one or more receptacles. The cover can include one or more hinge bars corresponding to the hinge sections on the base. The hinge bars can have an unequal aspect ratio allowing for easy insertion and removal of the cover. The cover can also include one or more protrusions separating the hinge bars. These protrusions correspond to the receptacles on the base. A method of stamping an article is also included wherein the stamping tool is provided. The cover is placed in an open position relative to the base. A stamp is adhered to the bottom surface of the cover. The article to be stamped is placed on the top surface of the base. A quantity of ink is applied to the stamp and, as the cover is placed in a closed position, the stamp is brought into contact with the article thereby stamping the article with the ink.

An apparatus for printing a beer barrel includes a workbench, and a hydraulic pushing device, a barrel outer-sided printing device, and a barrel inner-sided printing device installed on the workbench. The barrel inner-sided printing device has a turntable rotating with respect to the Z-axis and mounted on the barrel, an inner mold installed onto a circumferential surface of the turntable for printing the inner side of the barrel. The barrel outer-sided printing device has a connecting frame moving linearly along the Y-axis direction. The connecting frame has an outer mold for printing an outer side of the barrel, and the hydraulic pushing device controls the outer mold to move linearly along the X-axis direction. The outer and inner molds print a sidewall of the barrel. This invention prevents unnecessary waste of manufacturing cost and time caused by the scrap of semi-finished products whose previous printing process becomes useless.

A stamp device includes a main body. The main body includes a bottom plate on which a carrier and a stamp are placed, a pressing plate which cooperates with the bottom plate to press the carrier and the stamp, a limiting structure for limiting a lateral relative movement of the pressing plate and the bottom plate, and a connecting structure for folding and unfolding the main body. An upper surface of the bottom plate is provided with a working space for placing the carrier and the stamp. The present invention uses the pressing plate and the bottom plate to press the stamp and the carrier for stamping the pattern on the carrier. A movement space cooperates with a limiting member to limit the lateral movement of the pressing plate.
