Abstract

PURPOSE:To automatically execute the development processing of a film by detecting the feeding quantity of a feeding means for photographing, setting the conveying quantity of the film in a development processing room and conveying the film when the development processing is executed. CONSTITUTION:When a photographing button 25 is depressed, the film A by the amount as much as it is photographed is temporarily reserved in a waiting part because a pinching roller 12 is moved by an operation mechanism SL so that it may contact with a driving roller 13 which is rotated by a driving motor M1. Next, when a development starting button 24 is depressed, the film A is drawn because a driving motor M2 is started and a driving roller 20 which is directly connected to the motor M2 is rotated. Then, the film A is successively immersed in a developer tank and immersed in a fixer tank. Next, it is developed and ejected to the outside of a camera. Thus, when a count detected by a film moving quantity count mechanism 22 is read and it reaches a set value, the driving motor M2 of a feeding means for development processing is automatically stopped by a preset counter 23.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a judgment slit camera with an automatic developing device used to judge the order of finish in various competitions.

[Prior Art] Conventionally, in general, in a slit camera for determining the order of arrival, the film is developed by pulling it out from the rear of the camera into a darkroom and processing it with a developer and fixer prepared in advance by hand. ing.

[Problems to be Solved by the Invention] However, although the length of the film taken with the judging camera varies depending on the competition, it is usually about 20 cm to 2 m, then pulled out into a dark room and treated with developer and fixer at about 40°C. The processing time must be around 10 seconds, so
There were the following problems.

(1) Because the film is placed in the developing container all at once and then stirred by hand, the film may be damaged.

Particular care must be taken when processing a large amount of film (sometimes several tens of meters long).

(2) Because the emphasis is on speed, a darkroom for film processing is essential.

(3) Since manual development relies on cans, the quality may be inconsistent and uneven.

Therefore, in view of the above-mentioned conventional problems, the present invention has been made to solve this problem, and is an object of the present invention, which is a slit camera for judgment. To provide a slit camera for judgment with an automatic developing device, which mechanizes the developing process of film photographed by an operator, and allows even an unskilled person to easily, safely, and quickly process the film.

[Means for Solving the Problems] As a means for achieving this, the present invention provides a camera with a photographing room and a developing processing chamber, a photographing feeding means and a film waiting section in the photographing room, and a photographing chamber and a film waiting section. The chamber is equipped with a developing solution tank and a fixed @ solution tank, as well as a guide means for guiding and immersing the film in each solution tank, a solution temperature adjustment means, and a feeding means for development processing, so that the film loaded in the photographing chamber can be transported. After the film is pulled out by the photographing feeding means and photographed, it is sent to a waiting section in the same room, and the film in the waiting section is developed by the developing feeding means through the developer tank and fixer tank in the developing processing chamber. The film is automatically developed by detecting the feed amount of the photographing feed means, setting the film transfer amount in the developing processing chamber, and transferring the film.

[Example] An example of the configuration of the present invention shown in the drawings will be described in detail below.

Reference numeral 1 denotes a judgment camera, which is equipped with a photographing room 2 and a developing processing room 3, and the photographing room 2 is equipped with a photographing lens 4 and a scope 5 for checking the focus of the image incident from the photographing lens 4 through a mirror. A lens barrel section 6 is formed, and a film storage section 8 into which a film magazine 7 is loaded in a replaceable manner;
It has a photographing section 9 provided at the rear of the photographing lens 4, and a standby section 10 for temporarily storing and storing the photographed film A. A guide roller 11, a drive roller 13, and a pinch roller 12 directly connected to the drive motor M and arranged opposite to the rubber-coated drive roller 13 are used as photographic feeding means for sending out the image to the camera.
or installed. The developing processing chamber 3 is formed with a developer@liquid tank 14 containing a developer (tinB) and a fixed-if liquid tank 15 containing a fixer C. Each liquid tank 14.15 contains a film A.
Corrosion-resistant guide rollers 16, which serve as guide means for inducing immersion of the
A heater 17 for the stainless steel cartridge and a thermostat 18 for temperature adjustment are arranged in the developer tank 14 to heat the fixer C to about 0°C, and a heater 17 and a temperature control thermostat are arranged in the fixer tank 15 to heat the fixer C. Adjustment thermostat 18
is located. Even more certain! A rubber wiper 19 with a light shielding effect is attached to the discharge end of the liquid tank 15, and
A drive roller 20 having a feeding means for development processing on the discharge side is arranged directly connected to the drive motor M2, and the drive roller 2
Auxiliary rollers 21 and 21 are disposed facing each other on both the left and right sides of 0 to prevent slippage during film transport. As shown in FIG. 3, inside the guide roller 11 in the photographing room 2,
- A film movement amount counting mechanism 22, a preset counter 23 that detects this count and stops the drive motor M2 of the feeding means for development processing, and a development start button 24 are attached to the book guide roller 11a, and the drive roller 13 A photographing button 25 for controlling the electric actuating mechanism SL using a solenoid and a preset counter 23 are connected.

With this configuration, the judgment camera 1 is set above the goal line in advance, and the developer B and fixer C are stored in the respective liquid tanks 14 and 15 and heated to a predetermined temperature. Film A is pulled out from the film magazine 7 and hung on the guide roller 11, passed through the photographing section 9, between the pinch roller 12 and the drive roller 13, and then into the developer tank 1 of the processing chamber 3.
