Abstract: A foreign material removing structure includes an inserting hole, a battery-side terminal, and a push-out section. The hole provided in a battery pack extends in an attaching direction of the pack, and has an opening that a charger-side terminal can enter, the opening being formed in one end side in an extending direction. The battery-side terminal is provided in the hole to contact the charger-side terminal that enters the hole from the opening when the pack is attached to the charger. The section provided on the further forward side in the attaching direction than the opening in the pack has a surface that intersects the attaching direction. The structure is configured such that the section is at a region shifted to the further forward side in the attaching direction than the charger-side terminal when the forward side in the attaching direction of the battery-side terminal contacts the charger-side terminal.

Abstract: The advantage of the invention is to prevent the efficiency of printing from being deteriorated due to execution of an authentication process during a print process by arranging an authentication process not to be conducted during a print process. The multi-purpose device is connected to the authentication switch through the LAN. The authentication switch conducts an authentication process of a device connected to the LAN, and disconnects a connection between the device and the network in a case where the device cannot be authenticated. The multi-purpose device has the authentication requesting section that requests the authentication process with respect to the authentication switch; and the printing mechanism that prints print data. In a case where the printing mechanism conducts the print process, the authentication requesting section requests the authentication process before the printing mechanism starts the print process.

Abstract: Female guide portions for slidingly attaching a battery pack are formed by integral molding of a case main body. Exposed step portions are formed on the female guide portions, which includes protruding portions as thin-walled portions by application from the outer side (the upper side) of a mold so as to reduce the thickness of a thick-walled resin portion. An opening communicating with the inner and outer side of the case is not provided, while the protruding portions are formed as thin-walled portions. Bottom surfaces of the exposed step portions are formed so as to be sloped with respect to the horizontal direction when the battery charger is placed on a horizontal base, and water dropped on the bottom surfaces can flow outside of the case due to the slope without remaining thereon.
