摘要： A presentation system for a presenter to safely point out parts of an image projected from a projector onto a screen with laser light projected from a laser pointer held by the presenter is disclosed. The presentation system includes one or more infrared light receiving units on the laser pointer that selectively receive infrared signals from sending units that are mounted on the projector or on walls in order to control emission of laser light from the laser pointer. Arrangements of the sending and receiving units are designed to allow emission of the laser light from the pointer only when the laser pointer is pointed toward the projection screen. A control unit in the laser pointer may determine if the laser pointer is pointed correctly or a gravity operated shutter may further assist in preventing unsafe projection of laser light from the laser pointer.

摘要： A casing of a ball bearing which holds a ball screw can be displaced on a supporting stand against urging force of a compression coil spring and a tensile coil spring. If vibration of the ball screw is transmitted to the casing, the casing attempts to move on the supporting stand. However, when, due to the vibration, the casing is displaced against the urging force of the compression coil spring and the tensile coil spring, the urging force forcibly attempts to return the casing to its original position. A frequency of vibration of the casing is thereby forcibly changed.

摘要： A printing plate is held at one point thereof by a holding portion provided at a surface plate. When pushed by a pushing portion, the printing plate is only rotationally displaced. Thus, an angular error is substantially eliminated and displacement of the printing plate is small. Then, the pushing portion positions the printing plate in a direction perpendicular to a direction in which the surface plate can be moved. Then, movement of the surface plate positions the printing plate in the direction in which the surface plate can be moved.

摘要： An automatic exposure apparatus for printing plates and a method for exposing printing plates, which can prevent a defective image such as an unfocused image from being formed when an image is recorded onto the printing plate is provided. Suction holes are formed at a surface plate 110 of an automatic exposure apparatus 100 for printing plates, and a vacuum pump 306 communicates with the suction holes. A solenoid valve 308 is provided at a communicating path 304 between the suction holes and the vacuum pump 306, and a chamber 310 is provided at the communicating path 304 between the solenoid valve 308 and the vacuum pump 306. The solenoid valve 308 is closed and the vacuum pump 306 is operated in a state in which a photopolymer plate 102 is disposed on a top surface of the surface plate 110, and the solenoid valve 308 is opened completely in an instant in a state in which a pressure of a decompressed interior of the chamber 310 is a predetermined value or lower, such that the decompressed interior can suck air all at once from the suction holes with a strong suction force. Accordingly, a curled photopolymer plate 102 can be brought in complete contact with the top surface of the surface plate 110, and thus, a defective image such as an unfocused image is prevented when an image is recorded.
