A device for detecting a printing press for printing a securities printed matter with infrared ray ink of which spectrum characteristics in an infrared region are different from those under white light comprises, infrared ray irradiating means for irradiating infrared ray towards the securities printed matter printed and conveyed, image pick up means for taking an image on the securities printed matter, memory means for previously memorizing the image of a proper securities printed matter printed with infrared ray ink, by irradiating infrared ray, as a standard value, and judgment means for reading out the image memorized in the memory means, comparing an image taken by the image pick up means and the image of the standard value in order to improve an efficiency of quality control of a printing process and detecting process for a printed matter with infrared ray ink and a reliance of a detecting device.

Device for detecting matters printed with infrared ray reflective and

Sensor are widely used to read magnetic data and to read the magnetic and the optical patterns printed on notes and so on. A multichannel head in accordance with the present invention has plural magnetic cores arranged in a row and a cancellation core for noise removal, the head can detect magnetic characteristics as a whole in a stationary state without depending on the relative speed of the magnetic member with the head, and therefore is least affected by noise. Since one cancellation core is shared by plural magnetic cores, the structure as a whole becomes simple, and the cost of manufacture can be remarkably reduced. Since a magnetic head is combined with optical fibers in an integral structure according to this invention, it can read magnetic patterns and the optical patterns on the same location simultaneously by a parallel operation.

There has been proposed in prior art an identification device which identifies the denomination of a bank bill from the numerical figures thereon; however, it is of a simple type which recognizes the numerical figures by the variation of the light level reflected from the portion of a note having such numerical figures printed thereon by means of a sensor to thereby identify the denomination thereof. The device is detrimental in that a note is erroneously identified due to stains on the note. It is not quite practically usable as it is necessary to convey a note with one of the edges thereof placed under a strict control so that the numerical portion thereof should be surely passed through the sensoring position. According to this invention, one-dimensional image sensors are provided over the numerical portion on both sides of a note, signals output from the image sensors in time serial are encoded and characteristic signals for the numerical figures on the note are formed. The characteristic signals are stored for each scanning of the image sensors, thus stored data is computed to be compared with the reference data which has been stored corresponding to the denomination of notes, thereby identifying the denomination of the note.
