Abstract

PURPOSE:To prevent an obstacle to operation after supply of an unphotographed film, by returning a separated uppermost film to the layer position to arrange it in accordance with the opening operation of a cover by a recovering bar when the unphotographed film is supplied. CONSTITUTION:A film reset bar 65 is attached freely slidably to a box body 1, and a part (e) of the bar 65 is placed in the position shown by the solid line in figure when a switching cover 62 is closed by a compression spring 66. When the cover 62 is opened for the purpose of supplying an unphotographed film, a roller 64 is moved downward, and the recovering bar 65 is moved to the right position shown by the two-dotted line by a spring 66. In accordance with this operation, the uppermost film separated in the direction opposite to a photographing part is returned to the original layer position again by a prescribed scraping-out pawl and is arranged. Thus, the interruption due to the separated film is eliminated even when the film is supplied, and an obstacle to operation after this supply is prevented.

By rotating and parallelly moving ', the slide plate 13 and the return member 16 are rotated and parallelly moved in a clockwise direction (in the direction of the arrow).

When the return member 16 performs rotational parallel movement, the return member 1
6 comes into contact with the uppermost sheet film F', the shaft 12.12' continues its rotational parallel movement, but the slide plate 13 and the return member 16
By sliding the elongated hole portion with respect to the shaft 12.12', the return member 16
While maintaining the contact state, move the uppermost sheet film F' back to the side opposite to the photographing section. Furthermore, as the shaft 12.12' undergoes rotational parallel movement, the shaft 12.
．． 12' is in contact with the top of the elongated hole of the slide plate 13, the return member unevenness is separated from the uppermost sheet film F', and the slide plate i3 and the return member top 6 are in contact with the shaft 12.12'
6' is attached to the return member 16 by a return needle.

The slot and tor members 58 and 19 are integrally constructed,
The slit (portion a) formed by these has only a gap between the sheet film and the autumnal equinox, and by inserting the returned fc7 film into the slit, only one sheet can be separated.

The slit member 18 is rotatably supported on a shaft 22 provided on a lever 20 which is rotatably installed on a shaft 23, and is supported by a biasing force of a p1 torsion spring 24 and a roller 25 fixed to the slit member ram 9. The roller guide plate 58.58"t moves up and down as a guide.0 26 is the sheet film y returned in the opposite direction from the photographing section

The rear end of the sheet film F' is positioned to the photographing section.

The cam 27 fixed to the drive shaft 5 has a scraping claw 4L.
With the next cylindrical cam that is moved back and forth, the cylindrical cam rotates 270 times, centering around the fulcrum shaft 3o.
Cam Follow Afro 28 1. .

By swinging the lever 29 and sliding the rollers 31, the rollers 31 are connected with the tails and the bar a25 is slid. Since the shaft 34 fixed to the connecting lever 32 is tightly fitted into the elongated hole of the scraping lever 35.36, when the connecting lever 32 slides, the scraping lever 35.36 is moved to the fulcrum shaft 37. oscillates around the center.

Reference numeral 38 denotes a bottle fixed to a scraping lever 35, 36, which is tightly fitted into a long hole in the sheet metal 39. When the scraping lever 35, 36 swings, a guide 4 fixed to the sheet metal 39 is removed.
The sheet metal 39 slides back and forth as o slides using the side plates 3 and 4 as guides. 41 is a scraping claw fixed to the sheet metal 39, and is guided to the slit 6 of the tapered member 26. Sheet film F
This is to engage with both sides of the rear end and feed the tape sheet film F' to the photographing section. Here, the cam follower roller 28 is attached to the cylindrical cam 27 by a spring force.
The cam surface is traced.

Reference numeral 48 denotes a film pressing roller that presses down the edges of the laminated sheet films F other than the uppermost sheet film F', and 49 denotes a film pressing roller for pressing down the ends of the laminated sheet films F other than the uppermost sheet film F'. A guide claw that serves as a guide when the leading edge is pushed down and the uppermost sheet film F' is sent out to the photographing section; 50 is a guide roller at that time;
Reference numeral 46 denotes a stop and bar for preventing other laminated sheet films from being sent out to the imaging section when the uppermost sheet film F' is sent out to the photographing section.
The two members are integrally fixed to a metal plate 44, and are constantly lifted upward in the figure by the urging force of a torsion panel 45 about a fulcrum shaft 43 at a distance 111 of about 6 m from a stopper 52. The upper and lower cams of the film press roller 53 are fixed to the drive shaft 5, and the rotation of the upper and lower cams of the film press roller 53 allows the rollers 54' to be attached to the longitudinal part of the Jk sheet metal 44. 0, it is possible to swing the sheet metal 44, the film press roller 48, the guide claw 49, the guide row 250, and the stopper 46'f7r about the fulcrum shaft 43 at the same time in the vertical direction in the figure. Here, since the position when the film pressing row 248 is pushed down is always constant, as the number of laminated films F decreases, the vertical position of the sheet film F decreases, and the maximum The upper sheet film recorder is once returned in the direction opposite to the photographing section, and then the scraping claw 4
1, the effect of peeling off from other stacked sheet films F tends to decrease.

A film push-up sheet metal 55 is provided to compensate for the above drawbacks. This is a sheet metal for pushing up the vicinity of the tip of the sheet film on the photographing section side. ) is biased in the direction of the arrow in the figure. As the number of films F decreases, the number of layers increases.97
Il 5 FO waist strength weakens, film pushes up sheet metal 5
Since a constant force is always applied to 5 in the direction of the arrow in the figure, as the number of films decreases, the laminated film F increases in degree.

Therefore, even though the position when the film pressing roller 48 is pressed down is constant, the peeling effect of the uppermost O sheet film r and the other laminated sheet film F due to the action of the film pressing plate metal 55 is is kept almost constant. Next, we will explain the operation step by step.

In FIG. 2 showing the stop state mt, a large number of sheet films F are stacked on the film tray 2, the return needle member r6 is not in contact with the topmost sheet film F', and the scraping claw 41 is moved in the direction of the arrow. It shows where you are trying to return.

When a driving force to rotate the drive shaft 5 is transmitted from the body part main body in this state, the rotation shaft 7.7' begins to rotate and at the same time the return hand member 16 rotates in the direction of the hour hand (in the direction of the arrow). make parallel movements.

Eventually, the needle member 16 is returned to the uppermost sheet film d'.
The return needle 16' attached to the holder begins to come into contact with the holder. Furthermore, axis 7. As τ continues to rotate, the return needle 16' maintains contact with the uppermost sheet film F' and moves linearly back in the direction opposite to the photographing section, forming the film formed by the slit members 18 and 19. The center portion of the rear end of the sheet film F' is inserted into the sheet film-autumnal slit (FIG. 3, part 1). At the same time, both side portions of the rear end of the returned uppermost sheet film F' curve upward along the 0 portion of the tapered member 26, resulting in a state as shown in FIG. Before this state is reached, the scraping claw 41 has returned to the position shown in Fig. 3 of the rattan. When the shaft 7 further continues to rotate and the return needle 16' separates from the uppermost sheet film F' and performs a rotational parallel movement, the action of the scraping cylindrical cam 270 moves the scraping pawl 41 to the photographing section. The uppermost sheet film which is moving in the direction and curved upward by the taper member 26)
Engages with both sides of the rear end to send out the sheet film p/ to the photographing section. Immediately before this scraping operation begins, the film presser roller 48, guide claw 49, and guide roller 50 are operated by the film presser roller upper and lower cams 530. By pushing down the stopper 46 downward in the figure and pushing down the tips of the sheet films F other than the top sheet film y on the imaging unit side, only the top sheet film F can be sent to the main body of the imaging unit. . (Fig. 5) By operating in this manner, by rotating the drive shaft 5 once, the stacked sheet films F can be separated one by one and sent to the photographing section. In the operating sheet film feeding device, the stop position is when the uppermost sheet film F' is returned to the slit by the return member. This may occur due to the inconvenience that a sheet film other than the upper part of the board is inserted.
In order to eliminate this inconvenience, we will further explain the ninth mechanism for returning the separated uppermost sheet film r back into the slit to the same position as the other stacked sheet films.@1 Returning to the figure, reference numeral 62 denotes an opening/closing lid of the present sheet film feeding device, through which unphotographed sheet films are taken in and taken out. The roller 64 is rotatably supported on a shaft 63 attached to the opening/closing member 462 .

Further, a film return hole <-55 is slidably attached to the housing 1, and this hole is urged in the direction of the roller 64 by a compression spring 66.

When the opening/closing @ 62 is closed, the film return bar 65 is arranged so as to come into contact with the roller 64.
In the diagram, open and close! Since 62 is in the closed state, the C part of the film return hole 65 (the right end S of the left side bent part) is
The position shown by the solid line does not prevent the uppermost sheet film y from being returned in the direction opposite to the photographing section.

When the opening/closing lid 62 is opened in the direction of the arrow g in FIG. 1 (indicated by the two-dot chain line in FIG. The film moves to the position indicated by the two-dot chain line in the middle, and the uppermost sheet film F' has already been returned to the direction opposite to the photographing section, and the slit (second
Figure, Part 1) When K is inserted, the sheet film F' can be returned to the same position as the other stacked sheet films F. By opening the opening/closing lid 62 of the feeding device, the 0 portion of the film return part 65 moves to the position indicated by the two-dot chain line in FIG. It is not inserted into the slit and can be continuously fed out from the top sheet film to the spherical part. When loading unphotographed sheet film in several batches, the top sheet film of the already loaded sheet film is eroded due to the resistance of the sheet film to be loaded next. When some unphotographed sheet film is left in the film feeding device and the additional unphotographed sheet film is to be supplemented, the topmost ml of the remaining sheet film is inserted into the slit. It turns out. However, according to this embodiment, by opening the opening/closing lid 62, the sheet film in the slit is returned to the same position as the other laminated sheet films and arranged, so that sheet films other than the top one are placed in the slit. There is no inconvenience caused by the insertion.

Next, we will further explain the mechanism for returning the uppermost sheet film in the direction opposite to the direction in which it is fed into the photographing section in the above-mentioned sheet film feeding device. From the member 16Fi return needle 16' and the member with high frictional resistance (hatched area)), the tip of the return needle kg only protrudes a little from the surface of the member with high frictional resistance, so that the return needle 1
In order for 6' to cut into only one sheet film,
Sheet film f for second and subsequent sheets: Prevents it from being undone and does not cause scratches.

In Figure 182, reference numeral 67 indicates a needle retainer plate fixed to the film receiver 2, and a detailed cross-sectional view thereof is shown in Figure WL9.The needle retainer plate 67 is made of a material ( For example, Bakelite, etc.) and has a return needle of 16'.
The tip end of the needle slides in the groove of the needle guard plate 67. This is the 9th one that protects the tip of the return needle 16' when the last film in the stack of sheet films is returned when it is sent to the photographing unit, and when it is rotated idly with no sheet film. - Although the case is shown in which it is used as a means to return the top sheet film r in the direction opposite to the direction in which it is fed into the photographing section, there is no limit to the number of return needles. ◎Figure 50 shows the following: Nine embodiments are shown in which three return needles 16' are scattered on the return needle member 16. Further, in the embodiment, the return needles are scattered perpendicularly to the sheet film, but this is not necessarily necessary, and a structure may be adopted in which they are attached at an angle.

In order to protect the tip of the return needle 16', a groove is provided to protect the tip of the return needle 16'.
As shown in Figure 1, a needle retainer plate 68 that can slide in the direction of the arrow is attached to the film receiver 2, and is constantly returned to the right in the figure by a spring 69. The needle can be protected even if it is constructed so that it can be returned together.

According to the present invention described above, in order to return the uppermost sheet of film in the direction opposite to the direction in which it is sent to the photographing section, a return needle that only bites into the film - the autumnal equinox is used, so that the film can be returned reliably. The effect is great, especially when separating at high speed.In addition, the return needle can be applied outside one corner of the sheet film.
It does not look unsightly on reading.

Even if the laminated sheet film runs out,
The tapered tip of the return needle slides in the groove of the needle wire retention plate, and the tip of the return needle, especially the sheet film.
The part corresponding to the autumnal equinox is sufficiently protected @ Also, in the sheet film feeding device that operates as explained above, the uppermost sheet film that has been returned to the slit and separated is sent to the photographing section. Further explanation of the mechanism for taking out ◎In Fig. 4, scraping claws are attached to both il & li portions of the rear end of the uppermost sheet film F' guided by the slit (d) provided on the upper part of the taber member 26. 4
1 and move it in the direction of the arrow to remove the sheet film F'
Send it to the photography department. In FIG. 6, the scraping claw 41
A guide 40 that slides using the grooves of the side plates 3 and 4 as a guide is attached to the metal plate 39 that fixes the film plate 39. Also, a film member 614 is fixed to the metal plate 39, and the lower end surface of the member 61 is tapered. Slit of member 26) from part 2
-3rd eye is located at the bottom in FIG. 6, and bends the outer part of the uppermost sheet film F' beyond the scraping claw 41 downward in the drawing. When sending the uppermost sheet film F' to the photographing section, the film bending member 61 moves together with the scraping claw 41, and the scraping claw 4 of the sheet film F' moves in unison with the scraping claw 41.
Take out an 11-sheet film with the exogenous part curved from 1. This is done by bending the outer part of the sheet film F' to be scraped out, thereby creating a space between it and the other stacked sheet films, reducing the resistance between the sheet films, and reducing the uppermost sheet film F'. This allows the oysters to be served smoothly.

In the previous embodiment, the film bending member 61U scraping claw 4
Although the structure was designed to move in unison with Figure 1, Figures 12 and 13
The figure shows a case where a film bending member 70 is fixed to the side plates 3 and 4. When the uppermost sheet film F' is scraped out to the photographing section, the leading edge of the sheet film F' enters the photographing section side feeding roller. If the member 70 has this, it is possible to scrape out the notebook film F' while keeping the outer part of the scraping claw 41 curved.

As explained above, when the uppermost sheet film F' is fed 9 to the photographing section, if the outer part of the scraping claw 41 is bent while scraping out, one straight line will be drawn in the feeding direction of the sheet film. Not only does it have the effect of making the film stiffer as if it were passed through a streak, but it also creates a space between the stacked nine sheet films and reduces the resistance between the sheet films. ′ can be sent out smoothly. When this sheet film feeding device is used not only horizontally to the floor, but also vertically, and even upside down, the laminated sheet films J and F may fall down. However, since the direction of gravity applied to the sheet film is downward, the resistance between the sheet film r being scraped out and the laminated sheet film increases, which tends to cause scraping failures. Claw 4
According to this embodiment, in which the outer part of the sheet film 1 is scraped out while being curved, the resistance between the sheet films can be reduced, so that the effect is even greater.
