摘要： PURPOSE:To obtain a means and device for image reading capable of reading by switching different modes only by changing a scanning position by a common scanning mechanism without switching the optical path of an optical system to perform the reading of a reflected original picture and the transmission reading of a film original picture by a common one-dimensional sensor. CONSTITUTION:An image-forming plane by the transmission light of film (transmission original) 24' is formed on the same plane adjacent to an image-forming plane 28 by reflected light by an image reading means in which an opaque original 6 is irradiated with a light source 7, and the image-forming plane 28 is formed by the reflected light, and the image-forming plane 28 is read by scanning reciprocally by a reading body 4. The reading body 4 is enabled to scan reciprocally even on the image-forming plane 28 by the transmission light, and the opaque original 6 and the film 24' can be read by the same reading body 4.

摘要： PURPOSE:To provide more safety and higher reliability for a sheet transferring device by effectively transferring sheet originals. CONSTITUTION:Plural OHP films 28 are previously wound up around a core cylinder 6 together with a film sheet 8 in an opposite pressure to a description and held. Then, a pulse motor 27 is driven to transfer the OHP film 28 together with the film sheet 8 to a projection area A via transferring roller pairs 5, 16 in such a manner that the film sheet 8 is wound up around the core cylinder 6, and the motor 27 is stopped. To replace the OHP film 28, the pulse motor 27 is driven again to transfer the next OHP film 28 together with the film sheet 8 to the projection position A. Additionally, to reproject the film 28 which is already projected, the pulse motor 27 is reversely driven to transfer the OHP film 28 in an opposite direction for removal.

摘要： PURPOSE:To perform the continuous feed of sheets as a constant distance is provided between sheets by stopping a drive force, applied on a feed roller to feed sheets, for a specified time. CONSTITUTION:In a device to feed sheets P from a feed roller 21 rotated at a low speed to a main conveyance roller 27 rotated at a high speed, a waiting idling mechanism C is disposed on a rotary shaft 20 for driving the feed roller 21. When a sheet P fed from the feed roller 21 is conveyed by means of the main conveyance roller 27, the feed roller 21 is rotated at a high speed to increase an idling amount of the waiting idling mechanism C. When a subsequent sheet P is fed, the sheet P is fed after an idling amount is reduced to zero. This constitution performs the continuous feed of the sheets P with a specified distance provided between the sheets P through simple constitution, where an electric part to control rotation of the feed roller 21 is not used, and in a state that the drive means D is left continuously rotated.

摘要： PURPOSE:To reduce the floor area used, lower the height of a device, integrate a driving system, and miniaturize the device by arranging a load section and a discharge section vertically separately, arranging a sheet material conveying means between them, and concurrently using part of the load section as the discharge section. CONSTITUTION:A sheet material conveying device 20 has a load base 1A provided on the same side as a device main body 21 with the function to process the sheet material paper P, a paper discharging tray 9 serving as a discharge section, and a U-shaped conveyance path connecting the load base 1A and the paper discharging tray 9. A guide base 1B concurrently serving as a load base is arranged at the front of the downstream of the load base 1A, and a feed roll 2 guiding the paper P to the downstream is arranged above the guide base 1B. The paper P U-turned by a discharge roller 7 is guided to the paper discharging tray 9 via a paper conveyance path formed by a guide member and discharged. The paper P is guided by the paper discharging tray 9 on the rear end side and by the load base 1A concurrently serving as a paper discharging tray on the front side and stably discharged.
