摘要： An apparatus for holding a printing medium on a rotary drum, includes a rotary drum, a suction device, a medium holding mechanism and a medium removing device. The drum has a recess at its outer surface to extend along its rotation center line and rotates at a predetermined speed. A region of the outer surface, which is adjacent to a rearward end of the recess along the rotation direction, is smaller in the diameter than the remaining of the outer surface. The suction device holds by suction the medium onto the outer surface. The holding mechanism has a hook in the recess and selectively drives the hook between close and open positions. At the close position, the hook is placed over the adjacent region while being prevented from radially outwardly projecting from the remaining of the outer surface, and at the open position it is distanced from the adjacent region. When the medium arrives at the adjacent region, its leading end is held by the hook shifted from the open position to the close position and cooperated with the adjacent region and, when the drum rotates a specific number, the hook is returned to the open position. The removing device removes the medium from the outer surface when the drum rotates the specific number and the hook has moved from the close position to the open position.

摘要： Suction ports (14) are provided in one end (15R) of a drum (10), connecting the interior (16) and exterior of the drum (10). Corresponding suction ports (34) are provided at a stationary side (5R), opposing the suction ports (14), respectively. A suction fan (32) is provided, which draws air from the interior (16) of the rotating drum (10) through the corresponding suction ports (34) and the suction ports (14). A printing medium M can be attracted and held onto the outer circumferential surface (11) of the drum (10) by virtue of negative pressure, by utilizing the negative pressure generated in the interior (16) of the drum (10) as the suction fan (32) rotates and a plurality of suction holes (12) extending in a radial direction and connecting the interior and exterior of the drum (10). A damper (38) is provided at the air outlet port of the suction fan (32), for opening and closing the outlet port of the fan (32).

摘要： A ventilating fan including a ventilating fan body provided with a motor, a frame having ventilating air outlets, and fan blades, an adapter and an electric element box. The ventilating air outlets include a top air outlet provided on a top face of the frame of the ventilating fan and a side air outlet provided on a side face of the frame of the ventilating fan which are communicated with each other. The adapter is provided with a raised structure adapted to the ventilating air outlet. With this structure, the height of the ventilating fan is reduced while air volume is ensured, so that the ventilating fan is adapted to be mounted onto various ceilings, and the cost can be saved while mounting of the adapter is simplified.
