Filed: 1991-07-02
Abstract: PURPOSE:To prevent deterioration in the quality of a reproduced picture due to a moire stripe in the case of a dot print original by providing a moving means moving an optical image forming means by a prescribed quantity in the optical axis direction to the reader. CONSTITUTION:An optical head 10M is provided with a line sensor 11 and a light source 12 and the image of a reflecting light from a picture original GD is formed on the line sensor 11 through plane mirrors 13-15 and a projection lens (optical image forming means) 16. Then a moving device being represented by a motor 17 is provided on the projection lens 16 and a ROM 21 is connected to a motor control circuit 20. A data table of a moving quantity of the lens 16 corresponding to various sizes of the dot print original is stored in the ROM 21. In this case, it is possible to interleave properly an output of the line sensor 11 by utilizing it that the resolution of the picture reader is considerably higher than the resolution of a receiver and production of moire stripe is prevented in the case of a dot print original by limiting space frequency characteristic of the optical system to a required degree in response to the interleaving rate.

Title: Noncontact ic card
Inventor: OKAWA TAKEHIRO
IPC: B42D15/10
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To easily suppress the heat generation of an IC due to excessive electric power by connecting an antenna coil to a shunt regulator through a rectifying and smoothing circuit and setting the DC resistance value of the antenna coil much larger than the minimum DC resistance value of the shunt regulator. SOLUTION: The AC power received by the antenna coil 1 is converted into DC power through the rectifying and smoothing circuit 3 in an IC 2 and regulated to a specific voltage by a series regulator 4 which steps down the voltage to a voltage high enough to drive a logic circuit 5, so that the voltage is supplied to the logic circuit 5. Here, the DC resistance value of the antenna coil 1 is set larger than the minimum DC resistance value of the shunt regulator 6 and then the current flowing to the shunt regulator 6 is decreased to consume part of excessive power by the antenna coil 1. Consequently, the power consumption of the shunt regulator 6 in the IC 2 is reduced to suppress the heat generation of the IC 2.
