    摘要: In a printed matter identifying apparatus of the present invention, the light source (2) illuminates the detecting fields (3, 3') of the note (1). The reflected light-waves from the detecting fields (3, 3') are lead to the light receivers (10, 11, 10', 11') through the focusing lenses (4, 4'), the diffusion plates (5, 5'), the optical slits (6, 6'), the light conducting paths (7, 7') and red color transmitting and blue color transmitting filters (8, 9, 8', 9'). The output signals from the light receivers (10, 11, 10', 11') are amplified by the amplifiers (12, 13, 12', 13') and sampled by the sampling circuits (14,15,16,17). Among the sampled color component signals, the red component signals are applied to the subtracter (20) to produce the red component difference signal and the blue component signals are applied to the adder (21) to produce the blue component sum signal. These different signal and sum signal are applied to the comparators (27, 28) respectively and compared with the reference signals read out from the memory (24). The output signals from the comparators (27, 28) are supplied to the judgment circuit (29) where the judgement of the printed matter is performed.

    摘要: A printed matter (4), in which an ink capable of reflecting electromagnetic waves of wavelengths outside the visible range is used, is irradiated by electromagnetic radiation from a lamp (8) at least containing said wavelengths outside the visible range. Light reflected from the irradiated printed matter (4) is coupled to a photoelectric converter (12), the output of which is taken out through an amplifier (13). The printed matter (4) is inspected in terms of whether the level of the amplified output is high or low for a invisible wavelength range.

    摘要: Analog switches (3 i to 3 n ) are connected between corresponding photodiodes (1 i to 1 n ) and a common output line (4). The analog switches are sequentially scanned in response to scanning pulses (Ø 1 to 0 n ). During the ON period of each scanning pulse, the corresponding analog switch is turned on twice. A first circuit (C v , 5, 6, Ø R ) produces a first signal, including an image signal component and a noise signal component, when the analog switch is turned on for the first time, and produces a second signal including only the noise signal component, when the analog switch is turned on for the second time. A second circuit (11, 13) produces the signal derrived from the difference between the first and second signals, i.e., the image signal.

    摘要: @ There is a sorting apparatus for mixed envelopes according to whether or not the envelopes are face-up, and whether or not they are upside-down. Each envelope is carried lengthwise and a parallel light beam is radiated on the envelope from the right and left oblique directions with respect to the carrying direction of the envelope. When the light beam is radiated on the backside of the envelope from the upper side of the envelope, the shadow of the flap is formed on the envelope. Whether or not the envelope is face-up and whether or not the envelope is rightside-up is determined by this shadow detection.
