DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a negative film transport device in a negative film enveloper.

Generally, in a device for feeding and storing a negative film into a negative sheet, a so-called negative film enveloper, as shown in FIG.
While the negative film F stored in the negative sheet A is intermittently fed out by the negative film reel C, the negative film F stored in the negative film A is pulled out from the negative film reel C and transported on the negative film transport path D, and the negative film is inserted into the negative film insertion opening of the stopped negative sheet A. When the negative film F is inserted into the negative sheet A to a certain extent, the film cutting lever E is operated to cut the film, which is made up of an upper blade G and a lower blade H. By cutting the negative film F and pushing the rear end of the cut negative film F, the negative film F is accommodated in the negative sheet A.

As a means for pushing the cut negative film F into the negative sheet A, a negative film pushing device shown in FIGS. 2A and 2B has been used.

That is, the negative film feeding device shown in FIG. Then, the rear end of the negative film F that is not yet stored in the negative sheet A is pushed in with a finger, or as shown in _{FIG .} When the leading edge of the negative film F is inserted into the negative sheet A to a certain extent, it is cut by a cutting device consisting of an upper blade G and a lower blade H, and the cut negative film F is cut into a negative sheet by the inertia that has been fed. However, the former has a cutting device placed near the negative film insertion slot for negative sheet A, so there is a danger of cutting your fingers, while the latter has a cutting device placed near the negative film insertion opening for negative sheet A. There is an uncertainty that the negative film F may not be able to fully fit into the negative sheet A, or may bounce back and come out even if it does enter, due to conditions such as static electricity carried by the upper blade G and lower blade. A high-speed rotating roller _L1 ,
Since L ₂ is provided, space is required and the device tends to be large.

The present invention was proposed in order to solve the above-mentioned drawbacks and difficulties of the conventional apparatus, and is a method for cutting a negative film while it is being conveyed along a negative film conveying path and storing it in a negative sheet. The upper end of each arm rod is rotatably mounted on a fixed base installed below the negative film transport path in the enveloper at intervals in the negative film transport direction. The negative film is equipped with a negative film pushing member having a pushing part that appears on and disappears from the conveying path as the rod reciprocates in the same direction and pushes the rear end of the cut negative film on the conveying path. A negative film envelope comprising a film pushing link mechanism and an operation lever for operating the negative film pushing link mechanism linked to at least one of the separate arm rods. This is a negative film feeding device in Rotsupar, and it is safe because it does not use fingers to push it like the conventional device, and it uses inertia like feeding with high-speed rotating rollers. Since it is not a special item, it is possible to reliably store negative film in a negative sheet.

An embodiment of the present invention will be described with reference to the drawings. In FIG. 3, reference numeral 1 denotes a support shaft, and an operating lever 2 for operating a link mechanism for pushing negative film, which will be described later, is loosely fitted onto the support shaft 1. The operating lever 2 is swung about the support shaft 1 as a fulcrum.

Reference numeral 3 denotes a negative film pushing link mechanism part pushing pin member installed at the lower part of the operating lever 2;
₁ , 4 and ₂ are arm rods constituting the link mechanism section, and 5 is a beak-shaped part 5a as a pushing part at the top of the tip.
6 is a negative film pushing member used for pushing the rear end of the negative film, which serves as an upper side plate of the link mechanism section, and 6 is a fixed lower side plate serving as a fixed base constituting the link mechanism section. The arm rods 4 ₁ , 4 ₂ forming the link mechanism, the negative film pushing member 5 serving as the upper side plate, and the lower side plate 6 are rotatably connected by pins 7 ₁ , 7 ₂ , 7 ₃ , 7 _{4 ,} respectively. A link mechanism section for pushing negative film is constructed.

A long hole 5b is vertically bored in the front part of the negative film pushing member 5, which has the beak-like part 5a formed at the upper part of the tip. The portion is guided by a pin ₇₂ and is movable up and down.

Further, the distal end of the beak-shaped portion 5a is formed into a tapered pushing edge 5c that is inclined downwardly and inwardly.

Reference numeral 8 designates a first stopper for restricting the forward movement of the link mechanism for pushing the negative film, numeral 9 represents a second stopper for restricting the retreat of the link mechanism for transporting the negative film, and 10 represents a fixed lower side plate of the link mechanism. This is a spring stretched between 6 and arm rod ₄₁ .

Further, as shown in FIG. 1, reference numeral 11 denotes a long groove bored in the negative film transport path D, from which a beak-shaped portion 5a formed at the top of the tip of the negative film pushing member 5 emerges and retracts. do.

12 is a film feed roller.

Next, to explain the operation of the above-described embodiment of the present invention, the negative sheet A is transferred to the roller B for conveying the negative sheet.
On the other hand, the negative film F is pulled out from the negative film reel C, is transported along the negative film transport path D, is inserted into the negative sheet A, and to some extent the negative film F is inside the negative sheet A. When the negative film is inserted into the film (besides Fig. 1 and also see Fig. 4 A), the film cutting lever E is pushed down and the cutting device consisting of the upper blade G and the lower blade H cuts the negative film, but the negative film is not cut. The rear end of the negative film F protrudes from the negative sheet A. At this time, when the operating lever 2 is rotated manually or using a solenoid, motor, etc. in the direction of the arrow X, the operating lever 2 becomes unsupported. The lower part of the lever 2 swings and rotates about the shaft 1 in the opposite direction to the X direction, and the negative film pushing link mechanism part pushing pin member 3 is installed in the lower part of the operating lever 2.
The pin member 3 also swings in the direction of arrow Z, and this swing causes the pin member 3 to move the arm rod ₄₂ of the negative film pushing link mechanism installed below the negative film transport path D to move the link mechanism forward. It is pushed until it comes into contact with the first stopper 8 that regulates it.

By pushing the arm rod ₄₂ in the direction of the stopper 8, the link mechanism for pushing the negative film moves to the lower side plate 6.
is fixed, the negative film transporting member 5, which serves as the upper side plate of the link mechanism, moves forward, and as the negative film transporting member 5 moves forward, the beak-shaped portion 5a formed at the upper tip of the negative film transporting member 5 transports the negative film. The lower side of the protruding beak-shaped portion 5a that protrudes from the long groove 11 bored in the path D rides on the lower blade H. Since the hole 5b is drilled,
The negative film pushing member 5 moves forward smoothly to push the rear end of the negative film F, and during this pushing, the tip of the beak-shaped portion 5a formed at the upper part of the tip of the negative film pushing member 5 moves downward and inward. As described above, the lower side of the beak-like portion 5a rides on the lower blade H, so the tip of the beak-like portion 5a is slightly upward.
Since the tapered pushing edge 5c is substantially vertical, it can abut at right angles to the rear end of the negative film, ensuring good pushing (see FIG. 4B).

In this way, when the negative film F is completely accommodated in the negative sheet A, if the operating lever 2 is operated in the direction opposite to the arrow X direction to return it to its original position, the return force of the spring 10 and The arm rod ₄₁ of the link mechanism for pushing the negative film moves back until it comes into contact with the second stopper 9 for restricting the back of the link mechanism for pushing the negative film, and as it moves back,
Beak-shaped portion 5a at the top of the tip of the negative film pushing member 5
It is also recessed below the negative film transport path D to prepare for the next operation.

As described above, the negative film pushing device in the negative film enveloper according to the present invention operates the negative film pushing link mechanism disposed below the negative film transport path by operating the operating lever. The negative film pushing link mechanism, which operates the negative film pushing link mechanism linked to the operation lever, is provided with a pushing part for pushing the rear end of the negative film, which advances and retreats integrally with the link mechanism. Since the pushing portion of the member is made to protrude from the negative film transport path to push the cut rear end of the negative film, the negative film can be reliably accommodated within the negative sheet, and moreover, the negative film can be pushed out. Since the negative film is pushed simply by operating the link mechanism, the construction is extremely simple and the reliability is high, resulting in excellent practical effects.
