Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a sheet film storage device for sequentially stacking and storing exposed sheet films.

Prior Art The sheet film storage device includes a sheet film storage cassette that is removably installed in a photographic device that uses sheet film, and the sheet film storage cassette is configured to be able to open and close the exposed sheet film used in this device. They are received from the insertion slot, stacked one after another in a cassette in a dark room, and can be stored. In order to reduce the installation area of the apparatus, it is often used in a substantially vertical position, and the sheet film is stored in a cassette by dropping it from above.

As a result, a new sheet film falling from above in the cassette may hit the previously stored sheet film, or the sheet film may sag, making it impossible to store the specified number of sheet films. However, there was a problem in that the sheet film was damaged.

This phenomenon is particularly problematic when handling sheet films of different sizes.

Purpose The present invention was made in view of the above-mentioned conventional problems, and its purpose is to make it possible to regularly and sequentially stack exposed sheet films newly falling from above into a cassette. An object of the present invention is to provide a sheet film storage device.

Summary In order to achieve the above object, the sheet film storage device according to the present invention is used in a substantially vertical position, and is configured to sequentially stack and store exposed sheet films fed from a sheet film insertion port. a sheet film storage cassette having a bottom box for carrying the sheet film, and a top lid for covering the bottom box; an opening/closing means for opening and closing the top lid in conjunction with the feeding operation of the sheet film; a coupling means rotatably provided in the cassette to guide the sheet film to the bottom box; and a coupling means that is rotatably provided in the cassette to guide the sheet film to the bottom box, and is stacked on the bottom box as the top cover is opened by the opening/closing means in conjunction with feeding of the sheet film. a guide plate that moves to a position where it presses the vicinity of the lower end of the sheet film and moves to a position where the pressure is released as the opening/closing means closes the upper lid.

Embodiment Next, the present invention will be explained with reference to the drawings which are one embodiment.

In the figure, reference numeral 1 indicates a sheet film storage cassette (hereinafter referred to as
It's called a cassette. ), and is placed on a drawer device 4 provided in a cassette storage chamber 3 in the photographing device 2.

The cassette 1 has a bottom box 6 with a handle 5,
An upper lid 7 is provided on the bottom box 6 so as to be able to rotate around the bottom of the bottom box 6 to seal the inside of the bottom box 6 in a dark room. Inside this upper lid 7, a guide plate 9 having a roller 8 at its tip is rotatably supported by a first support shaft 10, and in order to always urge the guide plate 9 toward the bottom box 6 side, the upper lid 7 and the guide plate 9 are provided. A spring 11 is interposed between the plate 9 and the plate 9.

A first pin 12 is provided on the inner surface of the side of the bottom box 6, and when the top lid 7 is opened, a film insertion opening 14 is formed in the upper part of the opening to receive a sheet film 13 falling from above. When in a state,
The guide plate 9 is separated from the first pin 12, and the roller 8 at the tip is moved near the lower end of the bottom surface of the bottom box 6 without being affected by this, that is, when the sheet film 13 stacked in the bottom box 6 is already present. The sheet film 13 is pressed near its lower end. On the other hand, when the upper lid 7 is closed and the film insertion opening 14 is closed, the intermediate portion of the guide plate 9 is sandwiched between the upper lid 7 and the first pin 12. Therefore, the guide plate 9 rotates slightly clockwise in FIG. 1 about the first support shaft 10, and the roller 8 is separated from the bottom surface of the bottom box 6.

Further, V-cut locking pieces 15 are provided upright at both ends of the outer peripheral surface of the bottom box 6 opposite to the handle 5, and second pins 16 are provided protruding from both sides of the top lid 7. (See Figures 3 and 4).

Next, the drawer device 4 has a frame 19 formed by fixing side plates 18 to the side of the cassette platform 17 with an inclination of about 70 degrees. , a second support shaft 20 for supporting the cassette is attached, a notch 21 is formed in the surface of the cassette platform 17 for allowing a cam plate 24 (described later) to appear and retract, and a magnet 22 for suctioning the cassette is embedded. .

Further, behind the cassette platform 17, there is a camshaft 23 supported rotatably, a cam plate 24 integrally fixed to the camshaft 23, and a switch control plate 25.
A first pulley 26, a second pulley 28 attached to a motor 27 and the drive shaft, and a belt 29 wound between the first pulley 26 and the second pulley 28 are provided. Then, when the cam plate 24 is rotated by the motor 27 and rotated by a predetermined angle, the V groove 30 formed on the switch control plate 25 is connected to the detectors 31 and 3.
2, it is detected and stopped, and then it is made to operate in the opposite direction.

Furthermore, a rail 35 is installed horizontally on the intermediate frame 33 and the floor surface 34 that form the wall surface of the cassette storage chamber 3 that blocks light from the surroundings, and the drawer device 4 is slidably supported by this rail 35. It is installed so that it can be taken in and out of the photographing device 2.

The cassette 1 has the locking piece 15 engaged with the second support shaft 20 of the drawer device 4 having the above structure,
By attracting the cassette to the magnet 22, it is firmly placed on the cassette holder 17. When the second pin 16 engages with the cam plate 24 which rotates in synchronization with the feeding operation of the sheet film 13, the upper lid 7 rotates and the film insertion opening 14 opens to receive the sheet film 13. Next, when the cam plate 24 is reversed, a spring (not shown) urges the top lid 7 toward the bottom box 6.
It is formed to close the film insertion opening 14.

Next, the operation of the cassette 1 will be explained.

As described above, the cassette 1 is placed on the drawer device 4 and stored in a fixed position in the cassette storage chamber 3 in a dark room with the top cover 7 closed.

When the exposed sheet film 13 is fed from the photographing section (not shown) of the photographing device 2, the motor 27 is activated in synchronization with this feeding operation, and the top lid 7 is rotated by the cam plate 24. ,
The film insertion slot 14 opens and the sheet film 13 falls into the cassette 1.

However, at this time, the guide plate 9 is in a state of pressing the vicinity of the lower end of the bottom surface of the bottom box 6, and even if some sheets of sheet film 13 have already been supplied into the cassette 1, the guide plate 9 It is held down so that it does not sag. Therefore, the falling sheet film 13 does not collide with other sheet films 13, and first,
It falls to the roller 8 of the guide plate 9, and one end stops there.

Subsequently, the motor 27 reverses and is biased by the spring (not shown) to close the top lid 7, and the roller 8 moves toward the top lid 7 side and separates from the vicinity of the lower end of the bottom surface of the bottom box 6. As a result, a new The sheet film 13 falls from the position of the roller 8 to the lowest part of the bottom box 6. At this time, both the falling distance and falling speed are extremely small, so the sheet film 1
3 are sequentially stacked in the bottom box 6 in an organized state.

Thereafter, the above-mentioned operation is repeated, and when the specified number of sheet films 13 are stored in the cassette 1, the drawer device 4 is pulled out of the photographic device 2, the cassette 1 is kept in a sealed state, and the procedure is continued. When developing the sheet film 13, etc.,
Open the top cover 7 and place the sheet film 1 in a dark room as appropriate.
Take out 3.

Effects As is clear from the above explanation, according to the present invention, there is provided a bottom box which is used in a substantially vertical position and in which exposed sheet films fed from a sheet film insertion port are sequentially stacked and stored. , a sheet film storage cassette having an upper lid that covers the bottom box; an opening/closing means for opening and closing the upper lid in conjunction with the feeding operation of the sheet film; and an engagement provided on the upper lid and engaging with the opening/closing means. a stacking means rotatably provided in the cassette to guide the sheet film to the bottom box, and the sheets stacked in the bottom box as the opening/closing means opens the top cover in conjunction with feeding of the sheet film; and a guide plate that moves to a position where it presses the vicinity of the lower end of the film and moves to a position where the pressure is released as the opening/closing means closes the upper lid.

This prevents the sheet film stored in the cassette from falling or bending, and
As a result of being able to slow down the falling speed of the sheet film falling into the cassette from above, even when handling sheet films of different sizes, new sheet films will hit the sheet films already stored in the cassette. This prevents them from sinking in and allows them to be reliably stacked in an orderly manner within the bottom box. As a result, it becomes possible to utilize the cassette to its maximum capacity.

Furthermore, it not only prevents exposed film from being exposed even if the device is opened inadvertently, but also prevents damage to the emulsion surface of the film because the guide plate is designed to press against the lower edge of the film. Moreover, the falling distance of the film to the bottom of the cassette can be reduced, and the disadvantages of damage to the lower end of the film and unevenness of the film can be eliminated.
