Document Type and Number:
Japanese Patent JPH07295063
Kind Code:
A
Abstract:
PURPOSE: To make it possible to record a large quantity of data on a film with simple constitution without detecting the film feed speed of a camera.
CONSTITUTION: Recording is executed by a system of limiting the max. frequency fmax[Hz] at which LEDs flicker like fmax[Hz]<Vmin/ao when Vmin is defined as the min. speed among the speeds at which the film 10 is fed during the time after lapse of the specified time (t1) from the start of one frame feeding before the feed time t2 and (a) is defined as the width of dots 74 to be imprinted by an LED array 22 in such a manner that the overlapped recording of the adjacent dots 74 on each other is averted at the time of optically recording data codes at a data recording part 16 of the film 10.
