Title: Password collating system
Inventor: HIROKAWA KATSUHISA
IPC: G06Q40/00
Filed: 1984-04-18
Abstract: PURPOSE:To prevent a password from being decoded illegally by detecting a fact that an input for varying regularly the password is executed continuously, and deciding whether it is an illegal use or not based on a result of its detection. CONSTITUTION:In case a password is stored in a register 42, a CPU3 stores the present password in a register 41, and detects a regularity by a regularity detecting circuit 43. That is to say, the circuit 43 checks whether the first digit of the present password coincides with the first digit of the previous password or not. In case they do not coincide with each other, a difference of the password is calculated, and whether its difference coincides with a difference of the first digits of the time when the regularity is detected in the previous time or not. As a result, in case they coincide with each other, a count value of a regularity counter is added by ''1''. Also, in case this count value is reached a prescribed value (m), it is decided that a regular password is turned on, and an unavailable signal is outputted to the CPU3.

Abstract: PURPOSE:To easily align the front end of a paper to the front end of image formation by shifting a lens array in exposure position based upon variable power from a transfer position according to the variable power. CONSTITUTION:An original platen 24 is moved in variable power mode at a speed vo=v/a, where (a) is magnification and (v) is the moving speed of a photosensitive body 1. For example, when a reduced copy is taken, the platen 24 is moved at a speed faster than in unmagnification copying operation. Here, the time aDELTAl/v from when the original platen 24 is moved and a reed switch 32 is turned on to when the front end 25 of an original reaches a scanning start position 30 is DELTAl/v-aDELTAl/v earlier than the time aDELTAl/v when the front end of the original reaches the position 30 in unmagnification copying operation. For the purpose, the distance l2 between an exposure position 3-1 in reduction mode and an exposure position 3-2 in unmagnification mode is set to DELTAl-aDELTAl so that the exposure position 3-1 is at a longer distance to a transfer position 9 than the exposure position 3-2. Consequently, the front end of the paper is easily aligned to the front end of image formation on a recording medium.
