    摘要: In a reflecting type overhead projector, a reflecting table is formed of a Fresnel lens and a mirror laid together with the mirror lying close under the lens, and the original is laid against and above the lens. A lamp above the reflecting table projects light towards the original. A projection lens above the reflecting table projects an image of the original upon the screen. A photosensitive element near the reflecting table responds to the light from the lamp. A control circuit receives a signal from the photosensitive element and controls the intensity of the light emitted by the lamp. The control circuit supplies full power to the lamp, lighting it more brightly, when first the lamp is to be turned on. Thereafter, when the lamp is being supplied with full power so as to light it more brightly, and then the intensity of light radiation received by the photosensitive element drops substantially, the control circuit supplies part power to the lamp so as to light it less brightly; and, when the lamp is being supplied with part power so as to light it less brightly, and then the intensity of light radiation received by the photosensitive element rises substantially, the control circuit supplies full power to the lamp so as to light it more brightly. Thus when the operator's hand is put under the lamp the lamp is dimmed; and thus the danger of the operator being burnt by the light from the lamp is avoided.

    摘要: A mimeographic printing machine comprises a mimeographic printing means (2) for printing an image of an original document on successive sheets one at a time and for discharging the printed sheets; a sorter (3) having a plurality of bins (6) for receiving the printed sheets discharged from the mimeographic printing means; mode setting means (11) for setting up the sorter (3) for a specified mode such that a number of printed sheets, which are printed from the same original document and exceed the number of the bins (6) of the sorter (3), will be received on the bins in a specified order; and control means (2A) for detecting that the specified mode is set up by the mode setting means (11) and for controlling the mimeographic printing means (2) and the sorter (3) in such a manner that the printed sheets discharged from the mimeographic printing means will be received orderly one after another in the bins (6), from the first bin to the last bin, and then the following printed sheets discharged from the mimeographic printing means will be received orderly one after another in the bins from the first bin.

    摘要: The stencil duplicator includes: a cylindrical porous rotary printing drum and a means for selectively rotating it in a preferred direction; a means for clamping the leading edge of a stencil master along a generator of the printing drum; a means for supplying printing ink to the inner surface of the printing drum; a press roller means for pressing a paper sheet to the outer surface of the printing drum with a progressive rolling action; a means for feeding a paper sheet between the printing drum and the press roller means; a means for making a stencil master, including a light transmitting plate, a light source which selectively illuminates the light transmitting plate, and a pressure plate facing the light transmitting plate, with the light transmitting plate and the pressure plate being selectively able either to be separated or pressed together; a means for feeding the leading edge of a stencil master which has passed between the light transmitting plate and the pressure plate towards the clamping means so that it may be clamped thereby; and a means for controlling operation so that, when the light transmitting plate and the pressure plate are separated from one another with a stencil master interposed therebetween, the printing drum is rotated and by pulling via the clamping means on the leading edge of the stencil master withdraws it and wraps it around the printing drum.
