Abstract

PURPOSE:To prevent the leading end of a paper from entering a mask frame at the time of loading the paper and to prevent the paper from being scratched at the time of inserting a paper mask. CONSTITUTION:1st and 2nd guide boards 35 and 36 are attached on a path for inserting the paper mask 11 in the mask frame 14 so that the boards can be freely moved in the width direction of a color paper 10. When the paper mask 11 is pulled out, the opening of the mask frame 14 is covered with the guide boards 35 and 36. Thus, the color paper 10 can automatically be loaded. When a pressure lever 62b is rotated half, a cam board 63b is slid so as to bring the mask frame 14 downward. Thus, the mask frame 14 is located on a retreat position separated from the color paper 10, so that the leading end of the paper mask is prevented from abutting on the side edge of the paper even in the case of inserting the paper mask 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a belt-shaped printing paper (hereinafter,
It is related to a paper mask loading device used when printing on paper).

[0002]

2. Description of the Related Art Photographic printers use strip-shaped papers for efficient printing. When the paper is fed as it is when the belt-shaped paper is initially fed to the print position, the tip of the paper is curved into a gutter-like shape and escapes into the opening of the mask, and the tip of the paper hits the opening edge of the mask. For this reason, for example,
As shown in Japanese Patent No. 3138, a loading blind plate may be inserted so as to cover the mask opening. Also,
It has also been proposed to lift the paper upwards in conjunction with the insertion of the mask plate to retract the paper from the mask entry path when the mask plate is loaded in the print position (Japanese Utility Model Publication No. 62-176842).

[0003]

However, when the blind plate is loaded at the time of loading the paper, it is necessary to load the blind plate after each loading operation, and it is also necessary to remove the blind plate after loading. There is a problem that the work becomes complicated. In addition, when a guide member for retracting the paper is provided in association with the insertion of the paper mask when loading the paper mask, there is a problem that the mechanism becomes complicated. Moreover, the guidance at the time of initial feeding of the paper at the print position is not taken into consideration, and there is a problem when the paper is automatically loaded.

The present invention has been made to solve the above-mentioned problems, and makes it possible to automatically load color paper with a simple structure, and moreover, when the paper mask is loaded at the print position, the paper mask causes the side edge portion of the paper. It is an object of the present invention to provide a paper mask loading device which is protected from hitting.

[0005]

In order to achieve the above object, the present invention provides a machine frame, a mask frame for holding a paper mask so that the paper mask can be inserted in the width direction of the paper, and the mask frame in the machine frame. A mounting shaft that swingably holds near the insertion opening and a mounting path that is movable in the width direction of the paper in the insertion path of the paper mask within the mask frame, and is displaced between the print position and the position retracted from it. Paper guide member, a means for urging the paper guide member in the direction opposite to the insertion direction of the paper mask to set the paper guide member in the print position, and a side portion of the mask frame on the side opposite to the mounting shaft. A cam follower provided at the end, a cam plate that slides in the paper mask insertion direction, and a cam plate that is formed on the cam plate and engages with the cam follower to slide the cam plate into paper. Those having a cam surface for displacing between now separated state as disk frame are in close contact.

According to the second aspect of the present invention, the cam follower and the cam plate are provided on both sides of the mask frame.

According to the third aspect of the present invention, a stopper for restricting the insertion of the paper mask is provided near the paper mask insertion opening of the machine frame, and the stopper is provided when the mask frame is separated from the paper. It is formed to have a length such that it is retracted from the insertion path of No. 2 and enters the insertion path of the paper mask when it is in close contact with the paper.

[0008]

[Operation] When the paper is automatically loaded, the paper mask is pulled out from the print position. Since the guide member is biased by the biasing means in the paper mask withdrawing direction, the guide member is set in the opening at the print position in conjunction with the withdrawal of the paper mask. As a result, the guide member covers the opening, the tip of the paper does not hit the edge of the opening, etc., and the paper is automatically loaded smoothly. After auto loading, a predetermined paper mask is set. During this setting, the cam plate is slid to move the mask frame via the cam follower, and the mask frame is retracted so as to be separated from the paper on the print position. By retracting the mask frame, the stopper retracts from the mask insertion path of the mask frame. This allows the insertion of a paper mask. Therefore, since the mask frame is inserted when the mask frame is separated from the paper, the leading edge of the paper mask does not hit the side edge portion of the paper, and damage or damage of the paper is prevented. Further, after the insertion of the paper mask, the cam plate slides to move the mask frame via the cam follower and return the mask frame to the original position in which the mask frame is in close contact with the paper. In addition, when the mask frame is set at the print position and the paper mask is not loaded in the mask frame, the stopper is inserted in the mask insertion path, which prevents erroneous insertion of the paper mask. This prevents damage to the paper.

As shown in FIG. 1, the machine frame 12 and the mask frame 1
A mask frame retracting mechanism 55 is provided between the four side plates 14a and 14b. The mask frame retracting mechanism 55 rotates the mask frame 14 counterclockwise around the mounting shaft 13 to retract the mask frame 14 downward from the paper 10 in the paper transport path. Reducer 61, push levers 62a and 62b, cam plate 63a,
63b and cam followers 64a and 64b.
As shown in FIGS. 1 and 3, the rotation of the motor 60 is controlled by the speed reducer 6
The speed is reduced by 1 and transmitted to the rotary shaft 65 of the push levers 62a and 62b via the gears 61a and 61b. Engaging pins 66 are provided at the ends of the push levers 62a and 62b, and engage with the engaging grooves 67 of the cam plates 63a and 63b.

The cam plates 63a, 63b are side plates 14a, 14b on both sides of the mask frame 14 and side plates 12a, 1 of the machine frame 12.
It is slidably guided by a guide pin 68 between itself and 2b. The engagement groove 67 is formed by the cam plates 63a, 63.
It is formed to be long in a direction orthogonal to the sliding movement direction of b, whereby when the push levers 62a and 62b make a half rotation, the cam plates 63a and 63b go to the free end side of the mask frame 14, and when it makes another half rotation, Return to position. Further, as shown in FIG. 7, two slide rolls 75 are provided on the cam plate 63b. One end of the mounting shaft of the slide roll 75 is fixed to the cam plate 63b, and the other end is slidably fitted in the long hole 77 of the side plate 12b of the machine frame 12. Therefore, when the cam plate 63b slides, the displacement in the vertical direction orthogonal to the sliding direction is restricted. Further, as shown in FIG. 3, the other cam plate 63a
Also has a slide roll 76.

As shown in FIG. 7, cam plates 63a and 63b are provided.
A cam groove 80 is provided at the end opposite to the engaging groove 66. The cam groove 80 moves the mask frame 14 up and down in the figure by the reciprocating motion of the cam plates 63a and 63b, and is formed to be inclined with respect to the sliding direction of the cam plates 63a and 63b. The cam follower 64 is provided in the cam groove 80.
a and 64b enter and convert the horizontal displacement of the cam plates 63a and 63b into the vertical displacement of the cam followers 64a and 64b. As a result, the rotation of the motor 60 causes the push lever 62 to rotate.
When a and 62b make a half rotation, the cam plates 63a and 63b slide and move, and the cam follower 64 passes through the cam groove 80.
Since a and 64b move downward in the figure, the mask frame 14 rotates downward about the mounting shaft 13, and the mask frame 14 is at a position retracted from the paper transport path. Further, when the push levers 62a and 62b rotate to return the cam plates 63a and 63b to their original positions, as shown in FIG. 1, the cam follower 64b shifts upward through the cam groove 80, so that the mask frame 14 Is set at a position in close contact with the paper 10.
The push levers 62a, 62b and the cam plates 63a, 63
b, the cam followers 64a and 64b are provided on both sides of the mask frame 14, whereby the mounting shaft 13 of the mask frame 14 is attached.
It is possible to surely perform swinging around.

As shown in FIG. 8, when the mask frame 14 is retracted from the paper transport path, the paper mask 11 is inserted into the mask frame 14. Since the mask frame 14 is set at the retracted position separated from the color paper 10, even if the paper mask 11 is inserted into the mask frame 14, the tip of the mask does not hit the side edge of the paper 10 and the side edge of the paper is not touched. Damage to parts is prevented.

As shown in FIGS. 2 and 8, the mask frame 14 is provided with a stopper 85 for restricting the insertion of the paper mask 11 into the mask frame 14. The stopper 85 is configured by rotatably attaching a stopper block 86 to an upper cover plate 84 of the machine frame 12 by an attachment shaft 87. A guide roller 89 is attached to the stopper block 86, and guides the paper mask 11 when the paper mask 11 is pulled out. A coil spring 88 is attached to the attachment shaft 87. The coil spring 88 urges the stopper block 86 to rotate downward. As a result, the stopper block 86 is projected in the insertion path of the paper mask 11. The stopper block 86 has a locking portion 86a. The locking portion 86a locks on the lower end edge 84a of the upper cover plate 84 to regulate downward rotation of the stopper block 86. As a result, the mask frame 14 becomes the color paper 10
The stopper 85 projects into the insertion path of the paper mask 11 when it is set at the print position in close contact with the paper mask 11, and restricts the insertion of the paper mask 11.
Further, when the mask frame 14 is displaced from the print position to the retracted position, the stopper 85 of the stopper 85 is locked by the upper cover plate 84.
Since it is locked to the lower edge of the paper mask and does not rotate downward any further, the paper mask 11 is retracted from the insertion path, and the paper mask 11 can be inserted.

A plurality of paper masks 11 are prepared according to the type of print photograph. In addition to the paper masks 11 for group photographs such as graduation commemoratives as shown in FIGS. 1 and 9, FIG. Thus, for example, there is a postcard size paper mask 90. In this case, the position of the character-burning mask opening 90b is separated from the tip notch 91 of the paper mask 90 by a distance A, and this A is the same for all paper masks. As a result, even if the sizes of the paper masks 11 and 90 are changed, the first guide plate 35 is formed in the character mask openings 11b and 90b.
The lamp house 50 can be positioned. Reference numeral 90a indicates an image mask opening, reference numeral 92 indicates a postcard color paper, and reference numeral L in FIGS. 9 and 10 indicates the centers of the color papers 10 and 92. Further, reference numerals 93 and 94 indicate handle openings. As shown in FIG. 1, a lock lever 95 is provided on these openings 93 and 94 by a mounting shaft 97, and the paper mask 1
After inserting 1, 90, the mask frame 14 is locked by being locked to the lock pin 96 (see FIG. 4).

Next, the operation of this embodiment will be described. First,
During automatic loading of the color paper 10, the paper mask 11 is removed from the mask loading device. When the paper mask 11 is pulled out from the mask frame 14 from the state shown in FIG. 6, the guide plates 35,
The coil 36 is moved by the bias of the coil springs 38 and 39 to cover the opening of the mask frame 14 as shown in FIG. As a result, the leading ends of the color paper 10 are guided by the guide plates 35 and 36, and the color paper 10 is automatically loaded at the print position.

After automatic loading, the controller is in the paper mask set mode. In this mode,
As shown in FIG. 1, the motor 60 rotates to displace the mask frame 14 downward via the push levers 62a and 62b, the cam plates 63a and 63b, and the cam followers 64a and 64b. As a result, the mask frame 14 moves from the paper guide state shown in FIG. 1 to the retracted position away from the paper 10, as shown in FIG. In this retracted position, the mask frame 1
4 by the downward displacement, as shown in FIG.
Is retracted from the insertion path of the paper mask 11, the insertion of the paper mask 11 is permitted.

Next, the paper mask 11 is attached to the guide frame 14.
As shown in FIG. 4, the notch 45 at the front end of the mask is engaged with the locking plate 46 of the first guide plate 35 as shown in FIG.
Then, the first guide plate 35 moves in the back direction. Similarly, the second guide plate 36 also moves in the back direction. When the paper mask 11 is inserted all the way, the lock lever 95 of the paper mask 11 is locked to the lock pin 96, so that the paper mask 11 is fixed in the mask frame 14. In this state, the lamp house 50 is positioned in the character-burning mask opening 11b of the paper mask 14. After that, the mask frame 14 is displaced upward from the retracted position by the mask frame retracting mechanism 55 returning to the initial position.
The paper mask 11 is brought into close contact with the color paper 10. After that, the color film 10 has a lith film 15
Is printed and exposed. An image recorded on a negative film or the like is printed and exposed on the color paper 10 by a well-known printing and exposure mechanism. Thereafter, printing exposure is performed one after another in the same manner.

Further, in the case of printing exposure of another case, the paper mask 11 in which another lith film is pasted in the mask opening 11b for character printing is replaced, and a predetermined number of printing exposures are performed in the same manner.

When changing the paper, the motor 60 is rotated to set the mask frame 14 from the paper guide position to the retracted position. In this state, the used group photo paper mask 11 is pulled out. When the paper mask 11 is pulled out, the first and second guide plates 35 and 36 urged by the coil springs 38 and 39 move following the paper mask 11 to cover the opening of the mask frame 14. After that, the motor 60 rotates by a predetermined amount to return the mask frame 14 from the retracted position to the paper guide position. Next, the previous color paper 10 is rewound into the cassette, and a new size color paper is automatically loaded. After automatic loading, the mask frame 14 is set to the retracted position, and then a new paper mask 9 for postcards is used.
0 is inserted in the mask frame 14. As a result, the first and second guide plates 35 and 36 are shifted by the paper mask 90, and these are set to the retracted position from the paper guide position. Then, at the time of setting to the retracted position, the character plate mask opening 91 of the paper mask 90 is positioned on the lamp house 50 of the first guide plate 35 by the engagement of the engagement plate 46 and the tip notch 92. It After that, the mask frame 14 is set from the retracted position to the print position which is the same position as the paper guide position, and thereafter, the printing exposure is performed in a new size in the same manner.

In the above embodiment, the retracting mechanism of the mask frame 14 is driven by the motor 60 to push the pushing levers 62a and 62b.
The cam plates 63a and 63b are rotated by rotating the cam plates 63a and 63b.
63b may be shifted. Further, in the above embodiment,
The first and second guide plates 35 and 36 are provided, and these are stacked at the time of withdrawal to reduce the withdrawal space,
Although the device is compact, the number of guide plates may be one, or may be three or more.

[0027]

As described above, according to the present invention,
In the insertion path of the paper mask in the mask frame, a paper guide member that is displaced between the print position and the position retracted from this is provided, so when the paper mask is inserted into the mask frame, the paper guide member is pushed by this It will be automatically set from the paper guide position to the retracted position. Further, the paper guide member is provided with a means for urging the paper guide member in the direction opposite to the insertion direction of the paper mask. Therefore, when the paper mask is pulled out from the mask frame, the paper guide member follows the paper guide member from the retracted position. The position is automatically set. As a result, when the color paper is automatically loaded, the leading end of the paper does not hit the edge of the opening of the mask frame, and smooth paper feeding is possible. Moreover, it is not necessary to set a blind plate or the like at the mask position, and color paper can be easily loaded automatically.

Further, since the mask frame retracting means is provided and the mask frame is set to the retracted position away from the paper when the paper mask is replaced, the tip of the paper mask should not touch the side edge of the color paper. You can Moreover, it is not necessary to replace the paper mask by inserting a blind plate or the like, and the mask can be easily replaced. Further, since the mask frame retracting means is composed of a cam plate that slides and a cam follower that shifts by engaging with the cam groove of the cam plate, the mask frame is securely and smoothly centered on the mounting shaft. It can be rotated so as to be displaced between a position in which the paper is brought into close contact with the conveyance path and a position separated from the position. Further, since the cam plate, the cam follower, and the pushing lever are provided on both sides of the mask frame, the mask frame can be reliably swung and the mask frame is not twisted.

Further, a stopper for restricting the insertion of the paper mask is provided near the paper mask insertion opening of the machine frame. When the mask frame is separated from the paper, the stopper is retracted from the paper mask insertion path to remove the paper mask. When the mask frame is in close contact with the mask frame, the length of the mask frame is set so that it can be inserted into the paper mask insertion path. When in the close contact position with the road, the stopper comes into the insertion path of the paper mask. This prevents the mask edge from damaging the side edges of the color paper when the mask frame is in the paper guide position where it is in close contact with the paper, even if you accidentally try to insert the paper mask. It will not be lost.
