Abstract: An electronic device including a memory device with improved reliability is provided. The semiconductor device comprises a data pin configured to transmit a data signal, a command/address pin configured to transmit a command and an address, a command/address receiver connected to the command/address pin, and a computing unit connected to the command/address receiver, wherein the command/address receiver receives a first command and a first address from the outside through the command/address pin and generates a first instruction on the basis of the first command and the first address, and the computing unit receives the first instruction and performs computation based on the first instruction.

Abstract: An apparatus for automatically turning a page of a book comprises a casing 10 on which a music book 5 can be placed in an opened state; a page holding means 40 which is installed within the casing 10 and holds a page 6 of the opened music book 5 to be turned and a turned page 7 thereof; a page turning means 50 which is installed within the casing 10 to turn a page of the opened music book; a driving member 60 for driving the page holding means 40 and the page turning means 50, a manipulation member 110 for manipulating operations of the driving member 60, and a control unit 130 for controlling the operations of the driving member 60 for turning a relevant page of the music book 5 placed on the casing 10, in response to signals from the manipulation portion 110.

Abstract: The present invention provides an apparatus for turning pages of a music book. When a music performer manipulates a power switch, an actuating lever disposed in a housing of the apparatus is raised out of a guide groove of the housing and presses down and carries a right lower end of the page in accordance with an operation of a driving motor interlocked with the actuating lever. At this time, a pressure contact piece is moved in a fore and aft direction with respect to the page to press down or to be separated from the page so that the page can be smoothly turned. The actuating lever continues to pivot leftward along the guide groove to completely turn the page. After completing the operation of turning the page, the actuating lever is separated from the turned page and returns to an initial position along the guide groove.
