Abstract: A game device for playing a game accompanied by display of a character includes: an operation input interface; a management circuit configured to manage a time; a setting circuit configured to set a state of the character; a communication interface configured to communicate with an external device; and a controller configured to control an operation of the communication interface. The setting circuit is configured to set the state of the character to a first state when a current time falls within a predetermined time zone, and the controller is configured to enable the communication interface to communicate with the external device on a condition that the current time falls within the predetermined time zone and the state of the character is the first state.

Abstract: An electronic device cover includes a first cover portion configured to cover at least a part of an electronic device, the first cover portion being attachable to and detachable from the electronic device. The first cover portion includes a first convex portion configured to fit into a first concave portion provided in the electronic device and a second convex portion configured to fit into a second concave portion provided in the electronic device. When attaching the electronic device cover to the electronic device, a first insertion direction in which the first convex portion is inserted into the first concave portion and a second insertion direction in which the second convex portion is inserted into the second concave portion are different.

Abstract: A game device is configured to: cause a first character related to a game that is played on the game device to be displayed on a display; and perform communication by a first method of transmitting and receiving information to and from another game device and a second method of transmitting and receiving information to and from an external device. The game device is configured to: obtain information about a second appearing in the game that is played on the another game device from the another game device through the first method, and obtain information about a third character appearing in the game that is played on any one game device from the external device through the second method. The game device is configured to cause characters selected from the second character and the third character to be displayed in a predetermined area during the game.

Abstract: There is provided an additive processing device that models a workpiece by melting a supplied powder material and forming layers of the melted powder material. The additive processing device includes a laser head configured to supply the powder material to the workpiece and irradiate the workpiece with a laser beam, a drive unit configured to drive the laser head, a recognition unit configured to recognize a height of the workpiece in a laminating direction at a plurality of locations while the laser head is forming a predetermined N-th layer (N being a natural number) of the workpiece, an estimation unit configured to estimate a surface shape of the N-th layer of the workpiece based on the recognized heights at the plurality of locations, and a control unit configured to control the laser head and the drive unit.
