    摘要: An image reading and recording apparatus such as an electronic blackboard includes a reading unit movable along a guide rail for reading information written on a board, a drive motor integral with the reading unit and operative to move the reading unit relative to the board, and a power transmission mechanism for transmitting a driving force of the drive motor to the reading unit so as to move the reading unit relatively to the board. The power transmission mechanism is composed of a pulley fixed to a drive shaft of the motor and a wire rope extending along the guide rail in a stretched condition and wound around the pulley by one turn. Upon rotation of the motor, the pulley rolls on and along the wire rope, thereby moving the reading unit relative to the board. Due to a large contact area provided between the pulley and the wire rope, the movement of the reading unit is highly reliable and hence the information on the board can be read with high accuracy. The apparatus also includes an image recording unit which is so constructed as to prevent accidental separation of a recording paper from a recording head, thereby ensuring a high quality printing of the information on the recording paper.

    摘要: A waveguide type optical switch that can reduce the number of intersections in a matrix optical switch having the configuration of connecting unit optical switches and optical combining devices or optical branching devices to have a connecting function from “multiple inputs to one output” to “one input to multiple outputs”. To reduce the number of intersections in an entire matrix optical switch, an optical combining device of M inputs and one output is divided into (M−1) pieces of unit optical combining elements each having two inputs and one output, which are arranged immediately after (N−1) pieces of respective output ports excluding one piece of the output port closer to the input in the matrix optical switch out of N pieces of the output ports in the optical switch of one input and N outputs.
