Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a camera that captures images on film.

The processing method for the film used to photograph the manuscript involves winding the photographed film into a roll without any phenomenon occurring.
Once you have finished shooting one roll of roll film,
There is a so-called offline processing in which the rolled film is taken out of the camera and subjected to processing from the rolled film state, and the film is taken as is without being wound into a roll, or it is cut into a predetermined length. There are two methods, so-called online processing, in which the film is then sent to the phenomenon department for processing, but in conventional cameras, the photographed film is wound up in a roll, so only offline processing can be performed; In order to do this, it was necessary to have a processor camera that integrated a camera and a processor.

On the other hand, processor cameras cannot perform offline processing, and it is not possible to perform photography with a single camera that allows selection of both offline and online processing.

In view of the above-mentioned problems, the present invention provides a camera in which it is possible to select a photographing method that allows offline processing and a photographing method that allows online processing.

The present invention will be explained below using specific examples shown in the drawings.

58' and pins 155 on gear 154 are fitted into holes at both ends of a rigid connecting punch 158, respectively.
With the above configuration, when the gear 154 rotates once as described above, the swinging arm 157 reciprocates once within the range of arrow a (approximately 65 degrees), and the ratchet wheel 162 moves at an angle corresponding to one tooth (approximately 65 degrees). degree). More specifically, during the first half-turn (lower half) of the pin 155, the pin 158' moves to the right, but the ratchet wheel 162 and the ratchet pawl 160 slide against each other, so the ratchet wheel 162 stops. It remains as it is. During the subsequent half-turn of the pin 155, the pin 158' moves to the left in the range indicated by arrow a, but at this time, the tip of the ratchet pawl 160 engages with the teeth of the ratchet wheel 162, causing the ratchet wheel 162 to move. Rotate clockwise. This rotation is transmitted to a gear 168 that meshes with a gear 167 that is integrally connected to the shaft 163 of the ratchet wheel.
The film F pressed against the capstan roller 113' provided at 9 is fed by a fixed amount.

In the field of photographing the 16 mm film used in this embodiment, there are various film advance amounts for each photograph, but 10 mm and 11.75 mm advance are common. Therefore, in this embodiment, in order to easily meet the requirements for both feed amounts, the above structure is adopted. That is, the outer diameter of the capstan roller is 19.1 mm, the number of teeth of the ratchet wheel is 6, and the tooth ratio of gears 167 and 168 is adjusted to a pitch of 10.
In the case of mm, 1:1 (=50:50), feed amount 11.75mm
In this case, the above objective can be achieved by selecting 1:1.175 ((=46:54)).

Reference numeral 180 denotes a pressing lever for the pressure bonding plate 124 (Fig. 2), which is rotated counterclockwise (Fig. (in the clockwise direction).

184 swings about a shaft 185 protruding from the body 101 as a fulcrum shaft. It is a press release lever and has a roller 186 at one end that contacts the outer peripheral surface of the cam 156. This lever 184 is approximately 1/1/2 of the gear 154.
During two rotations, the large outer diameter portion of the cam 156 rotates counterclockwise via the roller 186, and the other end lifts the end 180a of the lever 180, resisting the spring 183, and rotates the shaft 127. Turn clockwise to release the film from the pressure bonding plate 124 against the avertature plate 123. This action is film F.
This is performed only when the film is in the feeding state, and when the film is stationary, the film is always pressed against the aperture plate 123 by the pressure bonding plate 124.

187 is a lever supported by a shaft 188 protruding from the fuselage 101;
pins 187a that are slidably fitted into the long holes of 82;
187b is planted. The lever 187 is
Although it is biased counterclockwise by a torsion spring 189 about the shaft 188, it is restrained in the position shown in FIG. 3 when the opening/closing cover (not shown) of the front film chamber is closed.

When the opening/closing lid is opened to load film into the film supply chamber, the lever 187 is released from its restraint and is rotated counterclockwise by the torsion spring 189, so that the levers 176 and 180 are moved clockwise. Pinch roller 113, pressure bonding plate 124

It has a driving part etc. The liquid processing section 220 is a developing device 35.
The film conveyed to the processor unit is developed, fixed, washed with water, dried, and wound onto the winding section 221.

As described above, according to the present invention, photographed film can be wound up into a roll or stored in a loop, and photographing can be performed so that both offline processing and online processing can be selected. For example, when photographing on general silver halide film, the photographed film is stored in a loop in a storage chamber, and this film is then sent to a silver halide film developer for processing, thereby completing the entire process from photographing to development. When photographing on color film, the photographed film is wound onto a take-up reel in the storage chamber, taken out from the camera, and developed in a color developing device. This allows offline processing.
