Description

[Detailed description of the invention] <Industrial application field> The present invention involves exposing an image to a photosensitive sheet using an image recording device such as an image scanning recording device or a copying camera for plate making, and then exposing the photosensitive sheet to a The present invention relates to an improvement in a photosensitive sheet collection box used for collecting exposed photosensitive sheets in a photosensitive sheet collection box and carrying the collection box to a developing processing chamber to develop exposed photosensitive sheets.

<Prior Art> As the photosensitive sheet collection box described above, the ones shown in FIGS. 6 and 7, for example, are conventionally known. This collection box 101 has an inner box 104 provided inside an outer box 102, and when this collection box 101 is attached to a pedestal 119 of an image recording device 113, the outer box 104 is disposed inside an outer box 102.
The opening 110 of No. 2 and the opening 111 of the inner cylinder 104 are aligned to form a photosensitive sheet entrance 112. In this state, the exposed photosensitive sheet 114
is the feed roller 1 of the image recording device 113
The cutter 1 is fed into the inner cylinder 104 by a predetermined distance by the cutter 13a, and then the roller 113a stops and the cutter 1
21 picks up the photosensitive sheet 114, and then rolls the roller 1 again.
13a sends out the rear end of the photosensitive sheet 114 and stops. After this, hold the handle 107 and remove the collection box 10.
4, the shutter 115 that had opened the photosensitive sheet entrance 112 rotates clockwise around a support shaft 116 and closes.

That is, a swinging lever 117 is fixed to a support shaft 116 of a shutter 115 that protrudes outside the outer box 102.
A tension spring 118 is hooked to close the collection box 101, and the collection box 101 is placed on the pedestal 1 of the image recording device 113.
19, the shutter opening contact member 120 provided on the pedestal 119 is attached to the tension spring 11.
8, the other end of the swing lever 117 is pushed up to open the shutter 115.

<Problems to be Solved by the Invention> However, in the conventional example described above, the terminal end of the photosensitive sheet 114 fed out from the feeding roller 113a is located outside the shutter 115, that is, in the outer box 102.
This causes so-called fog to occur. Moreover, when the base portion of the photosensitive sheet 114 has translucency, light enters from there and the shutter 115
Fog may occur even inside the part that closes.

<Means to solve the problem> In order to solve the above problems,
The present invention is an improvement of the conventional photosensitive sheet collection box as shown in FIGS. 1 to 5, for example.

That is, while supporting the inner cylinder 4 rotatably,
A rotating means 8 is provided in the inner cylinder 4, and the rotating means 8 is connected to the outer box 2.
By operating the inner cylinder 4 from the outside, the inner cylinder 4 is configured to be rotatable between an inlet open position A in which the opening 11 thereof is aligned with the opening 10 of the outer box 2, and a closed position B in which the inner cylinder 4 is in a closed state. , a friction plate 15 is pasted on the outer circumference of the opening 11 of the inner cylinder 4 so as to face the outer circumferential surface of the inner cylinder 4 to close the opening 11 at the closed position B of the inner cylinder 4, and a terminal end 14a of the photosensitive sheet 14 is attached. A shielding plate 17 is provided to accommodate the inner cylinder 4 at the closed position B.
The device is characterized in that the end portion 14a of the photosensitive sheet 14 is drawn between the inner tube 4 and the shielding plate 17 and is shielded from light by rotation.

<Operation> Operate the rotation means 8 to move the inner cylinder 4 to the inlet opening position A.
When the opening 10 of the outer box 2 and the opening 11 of the inner cylinder 4 are rotated to the extent that the photosensitive sheet entrance 12 is formed, the photosensitive sheet 14 can be recovered.

Next, the exposed photosensitive sheet 14 fed by the feed roller 13a is collected into the inner cylinder 4, with its terminal end 14a protruding outside the outer box 2. Next, when the rotating means 8 is operated to rotate the inner cylinder 4 to the entrance closing position B, the photosensitive sheet 1 protruding from the opening 11 of the inner cylinder 4 is removed.
The terminal end 14a of the inner cylinder 4 is connected to the outer circumferential surface of the inner cylinder 4 by the frictional force of the friction plate 15 as the inner cylinder 4 rotates.
At the same time, the opening 10 of the outer box 2 and the opening 11 of the inner cylinder 4 are closed. As a result, the end portion 4a of the photosensitive sheet 14 is completely shielded from light, and no fogging occurs.

Further, in order to take out the photosensitive sheet 14 from the collection box 1, the inner tube 4 is rotated to the entrance opening position A by operating the rotating means 8. Then, contrary to the above closing operation, the end portion 14a of the photosensitive sheet 14 protrudes from the opening 10 of the outer box 2 again due to the frictional force of the friction plate 15. Thereby, the photosensitive sheet 14 can be taken out from the collection box 1.

<Examples> Examples according to the present invention will be described below based on the drawings.

FIG. 1 shows a photosensitive sheet collection box of the present invention, a partially cutaway perspective view, FIG. 2 a partially cutaway front view, and FIG. 3 a sectional view taken along the - arrow in FIG. FIG. 4 is a sectional view showing the state at the closed position B of FIG. 3.

In these figures, reference numeral 1 indicates the entire photosensitive sheet collection box, 2 indicates an outer box, 4 indicates an inner cylinder, 8 indicates a rotating means, and 14 indicates a photosensitive sheet.

The photosensitive sheet collection box 1 includes an outer box 2, an inner cylinder 4 rotatably supported within the outer box 2, and a rotating means 8 for rotating the inner cylinder 4.

The outer box 2 has a relatively large rectangular opening 10 on one side thereof, and an opening frame 10a is attached and fixed to this opening 10.

The inner cylinder 4 has a slit-shaped opening 11 in its longitudinal direction.
A support shaft 5 of an inner cylinder 4 is rotatably supported by support frames 3 erected on both sides inside the outer box 2.

The rotating means 8 includes a pair of swinging levers 6, 6 that are fixed to both ends of the inner cylinder 4 and protrude outward from the notch 9 of the outer box 2, and is constructed across both swinging levers 6, 6. The inner cylinder 4 can be rotated by holding the handle 7, and the collection box 1 can be carried.

Hold the handle 7 and rotate it to open the entrance to position A.
Then, as shown in FIG. 3, the opening 11 of the inner tube 4 appears within the opening 10 of the outer box 2, and the photosensitive sheet entrance 12 is exposed.
form. Thereby, the exposed photosensitive sheet 14 fed out from the feeding roller 13a of the image recording device 13 can be collected into the inner cylinder 4.

A friction plate 15 having a large friction coefficient, such as a rubber sheet, is attached to the outer circumference of the inner cylinder 4 near the opening 11 above the opening 11, that is, on the clockwise side. Then, on the lower side of the inner cylinder 4, facing the outer peripheral surface of the inner cylinder 4, a soft brushed rasher cloth 16 is placed.
A shielding plate 17 is provided.

The terminal end 14a of the photosensitive sheet 14 fed by the feeding roller 13a comes off from being held by the feeding roller 13a and protrudes outside the outer box 2.
When the photosensitive sheet 14 is rotated to the inlet closing position B, the terminal end 14a of the photosensitive sheet 14 protruding from the opening 11 of the inner cylinder 4 is moved around the outer periphery of the inner cylinder 4 by the frictional force of the friction plate 15 as the inner cylinder 4 rotates. It is dragged between the surface and the shielding plate 17, and is completely shielded from light.
The opening 11 of the inner cylinder 4 is closed by a shielding plate 17, and the photosensitive sheet entrance 12 is closed. FIG. 4 shows the state at this time. The rasher cloth 16 is used to prevent scratches on the photosensitive sheet end portion 14a when it is drawn in and to improve light shielding properties, but is not necessarily required. When taking out the photosensitive sheet 14, the end portion 14a comes out from the opening 10 of the outer box 2 by operating the handle 7 in the opposite direction inside the darkroom. Reference numeral 11a is a hand insertion opening formed by hollowing out the center of the slit opening 11, and is used to take out a short photosensitive sheet 14 when it enters the inner cylinder 4.

In FIGS. 2 to 4, reference numeral 18 is a light-shielding plate fixed in the longitudinal direction of the inner cylinder 4, and 19 is a ring-shaped light-shielding rib provided at both ends of the inner cylinder 4. A light shielding plate 18 connects the collection box 1 to the image recording device 1.
This is to prevent light from entering through the gap between the inner cylinder 2 and the shielding plate 17 when removed from the outer case 2.
This is to block light from entering. Both of these light shielding members 18 and 19 are effective in increasing the light shielding property, but if only the light shielding by the shielding plate 17 is sufficient, these light shielding members 18 and 1
9 is not necessarily required.

In addition, reference numeral 20 is a hook for attaching a collection box that is arranged at a predetermined interval on the front side of the upper part of the outer box 2, 21 is a pair of engagement rings for attaching and fixing provided at both ends of the inner cylinder 4, and 22 is an image. This is an engagement roller provided oppositely to a pair of arms 22 protruding from the recording device 13 side.

To attach the collection box 1, first lift the handle 7 and attach the hook 20 to the support 24 of the image recording device 13.
to be locked. At this time, since the swing lever 7 is in the closed position B shown by the imaginary line in FIG. 3, the collection box 1 as a whole is tilted forward, making it easy to lock the hook 20 to the support 24.

Next, the handle 7 is slowly pushed down to lower the swing lever 7 to the entrance opening position A. At this time, the engagement roller 22 is connected to the outer box 2 shown in FIGS. 1 and 2.
It is inserted through a pair of insertion holes 25 formed on both sides of the front surface, passes through the notch 21a of the engagement ring 21, and rides on the inner peripheral surface of the engagement ring 21 as the inner cylinder 4 rotates. . As a result, when the inner cylinder 4 is at the entrance open position A, the collection box 1 is completely installed, and the photosensitive sheet entrance 1 is opened as described above.
2 will be formed.

In the above embodiment, the rotating means 8 of the inner cylinder 4 is operated by the handle 7, but the invention is not limited to this. For example, as shown in FIG. Connect the support shaft 5 of the inner cylinder 4 to the outer case 2
A swing lever 27 is fixed to the protruding support shaft 5, a tension spring 28 is sealed in the swing lever 27 to close the photosensitive sheet entrance 12, and the photosensitive sheet is mounted on a pedestal 29. Then, the contact member 30 provided on the pedestal 29 pushes up the other end side of the swing lever 27 against the tension spring 28, and the photosensitive sheet entrance 12
You may also open it.

<Effects of the Invention> According to the present invention, which is constructed as described above, the end portion of the photosensitive sheet is completely shielded from light, so that fogging does not occur as in the conventional example. In particular, when the rotating means of the inner cylinder is rotated by hand, it can be operated with a single touch, making it convenient to carry.
