As for the slit camera which is used at the racecourse, the precision is high to be made in the professional manufacturer.
On the other hand, the slit camera to introduce by this home page is the camera which remodeled a general camera.
It introduces about the slit camera which I manufactured until now.

The first slit camera The slit camera and controller

This is the first slit camera which I made.
The camera which was made the base of the manufacturing is a half-size camera.
The lens puts a mount and it is possible to exchange.
The box of the side of the camera is the equipment to control a camera.

The No.2 slit camera

It is the 2nd slit camera which I made. The point which is different from the 1st set
is the thing the photography about which is possible even if the train comes from
any either side direction.
Therefore, it installed a frame in the camera and a camera was made to be able to be
installed in the tripod reverse, too.
However, as for this camera, the clenching of a gear didn't go successfully and wasn't
used once after all.

The No.3 slit camera by a single-lens refrex camera

It is the first slit camera which remodeled a single-lens reflex camera. This camera
can be installed in the tripod reverse.
The one which is on the left side of the camera is the box which stores a rolled film.
A film is wrapped around the about 4 cm diameter cylinder axis.
It used a single-lens reflex because it was easy to set a camera for the direct
subjectto be able to be seen through the lens.
Also, it puts a magnet to the turn axis for film counter - and it is detecting number of
rotations by lead-switch. Because the striped pattern comes out in the image, it isn't using this No.3 slit camera at present.

The No.4 slit camera The No.4 slit camera to have diverted
into the equipment of film scanner

This new slit camera didn't roll up a film to the axis and took a moving method at the
interval of two squeegees which turn a film. At low speed, it was not in the problem
when charging and turning an actual film but it found that it had slipped between the
film and the squeegee when becoming high-speed.
Therefore, it gave up to use this camera as the slit camera and it decided to divert the
part of the drive equipment as the electric film movement equipment of film scanner.
There is a film scanner behind this equipment.
The film which was read through the squeegee is appearing structure from the center
of this equipment.
The lever in the right is the one of the purpose to put a film in the squeegee and to
remove it.


The No.5 slit camera front The No.5 slit camera back


This is the newest slit camera which I made until now.
The characteristic of this camera is to have used worm-gear for the gearing.
It installed an aluminum frame for the photograph to be able to be taken in the tripod
reverse like the previous slit camera.
The motor is using large-sized mabuchi's RS-540SH for the radio control.
It is put to the side of the camera in the box to store the film which was rolled up like
the No. 3 slit camera.
