Inventor: NAKAHARA YOSHIHIKO
IPC: C09D7/12
Filed: 1986-11-13
Abstract: PURPOSE:To obtain a true/false decision method of extremely high security by forming a recording medium in such a manner that at least the magnetic polarities of the edge part thereof represents a code for true/false decision, detecting the magnetic polarities thereof and collating the combination of said polarities with a correct combination. CONSTITUTION:A magnetic card 1 is provided with three pieces of magnetic recording tracks T1-T3 on the magnetic layer oriented in one direction and, for example, only the magnetic polarity in the edge part of the track T2 is inverted. An N-S-N or reverse combination is, therefore, obtd. if the polarity of the edge part is detected. Such polarity is utilized as the code for true/false decision of the magnetic card. If, for example, the magnetic card 1 is a prepaid card, the balance changes at every use and, therefore, the code for true/false decision is determined from said balance. The code for true/false decision is updated at every use. The falsification of the balance is thereby easily discovered even if such falsification is made.

Title: Color image forming device
Inventor: SAKAUCHI KAZUNORI
IPC: G03G15/16
Filed: 1989-10-19
Abstract: PURPOSE:To prevent the misregistration of superimposed images by setting the unseparated length of transfer paper of maximum size from a transfer paper carrying belt to a fixed value or above. CONSTITUTION:A resist roller 16 feeds the transfer paper on the transfer paper carrying belt 17 destaticized by a destaticizer 22 to an almost 0 V. At a transfer point T, a transfer paper is electrostatically attracted to the transfer paper carrying belt 17, and the transfer paper is carried. Upon the transfer completion of the first image, the transfer paper carrying belt 19 instantaneously enters a return action. As the return action proceeds, the trailing edge of the transfer paper is separated by a transfer follower roller 19 because curvature varies. At this time, the holding or carrying force of the transfer paper is created by the attracting force of an attracting allowance (c). Since the unseparated length (c) of the transfer paper 33 of maximum size from the transfer paper carrying belt 17 is 20 mm or above, the misregistration of images to be transferred is prevented.
