Title: Kouichi Daitoku: Innovator in Film Technology

Introduction

Kouichi Daitoku is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of film technology, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is a motor drive device for long-footage film. This device features a first motor for effecting shutter release and driving a constant-amount film feeding sprocket. It also includes a second motor that initiates the take-up of the film onto a spool upon the movement of the sprocket. A timing circuit generates a shutter release signal that drives the first motor to effect shutter release immediately after the complete stoppage of the second motor. This timing circuit repetitively generates such a shutter release signal at a specific time interval.

Another significant patent is for film frame counting devices for still cameras. This counting device indicates the exact number of frames of long-footage film exposed during regular photography. It includes a numerical counter and a drive gear that rotates in response to film movement, increasing the count by one for each frame of film advance. The drive gear changes the count only after the advance of the leader portion of the film. A cam, incrementally rotated by an escapement mechanism, moves a release lever to prevent counting during the advancement of the leader portion and permits counting thereafter.
