Description

[Detailed Description of the Invention] The present invention relates to an improvement of an easel mask in a photographic printer device having an automatic loading mechanism for roll photographic paper. In an easel mask whose printing screen size can be adjusted, the opening of the easel mask is closed by the two slide members during autoloading of the roll of photographic paper, and at least one of the two slide members is introduced. An easel for autoloading, which is provided with a paper guide member that projects in conjunction with a side slide member and serves as a guide, protruding from the front of the introduction side slide member in the direction in which the photographic paper roll is introduced, thereby enabling smooth running of the photographic paper roll. It is a mask,
The present invention relates to a structure that does not require an additional drive unit as a drive unit for the guide member.

Conventionally, this type of easel mask for autoloading uses a hole (opening) in the easel mask.
When automatically loading a roll of photographic paper, a flap that can be rotated is provided, and the flap is rotated to serve as a path (guiding means) for the roll of photographic paper. This has the disadvantage that a separate section is required, which makes the structure complicated and large, which is not desirable.

The present invention has been developed in view of the above-mentioned drawbacks, and the present invention will be described in detail below based on one embodiment with reference to the accompanying drawings.

1 is a cutout support portion 1a for housing and supporting a pulse motor support plate 3 on which a pulse motor 2, which is an easel mask driving power source, is installed;
It is an easel body having 1a.

4 is a pinion that is integrated with the rotating shaft of the pulse motor 2, and 5 and 5 are in mesh with the pinion 4, respectively, and are slidable through long grooves 3a, 3a formed on the pulse motor support plate 3. It is a rack installed like this, and the rack 5,
At the tip of 5 is a slide pin rod bearing for storing and supporting slide pin rods 10, 10' connected to two slide plates 7, 7', which are members for adjusting the printing screen size in the longitudinal direction, which will be described later. 5a, 5
a are provided respectively.

Reference numeral 6 is an easel mask section, and to explain its structure in detail, 7 and 7' are two slide plates that are members for adjusting the printing screen size in the longitudinal direction, and the easel mask size in the width direction. It is slidably attached to the two fixing plates 8, 8' that determine the distance by using their long grooves 8a, 8a'(8a' is not shown).

Fixed plates 9 and 9' are fixed to both ends of the bottom surfaces of the fixed plates 8 and 8', respectively.

A slide pin rod 10 is rotatably supported on support levers 7a, 7a' fixed to the bottom surface of the slide plate 7, and the slide pin rod 10 is rotatably supported.
0, a paper bridge (paper guide member) 11 having a rotatable connecting pin rod 12 passed through both side surfaces thereof is supported so as to be rotatable about the slide pin rod 10 as an axis.

Further, each of the support levers 9a, 9a fixed to the bottom surface of the fixed plate 9 has a bridge lever 1.
3, 13 are rotatably supported, and a long groove 1 formed in the bridge levers 13, 13.
The connecting pin rod 12 of the paper bridge 11 is fitted into 3a and 13a, and the two are connected by an E ring or the like on top of the connecting pin rod 12, so that the paper bridge 11 is integrated with the slide pin rod 10. When operating in conjunction with the slide plate 7, the long groove 13
a, 13a, the link mechanism is configured to allow for natural interlocking.

Further, a slide pin rod 10' is rotatably supported by support levers 7a', 7a' which are similarly fixed to the bottom surface of the other slide plate 7'.
Further, each slide pin rod 10' has a long groove 13.
Two bridge levers 13', 13', on which a', 13a' are formed, are rotatably supported.

Further, the support levers 9a', 9a' fixed to the bottom surface of the other fixed plate 9' are equipped with paper bridges (paper guide members) having rotatable connecting pins 12' passed through both side surfaces thereof. 11' is rotatably supported, and the connecting pin 12'
are fitted into the long grooves 13a', 13a' formed in the bridge levers 13', 13', and the two are connected by an E-ring or the like on the grooves.Therefore, the paper bridge 11' stick 1
When operating in conjunction with the slide plate 7' integrated with the slide plate 7', the existence of the long grooves 13a', 13a' allows for smooth interlocking by the link mechanism.

Since the present invention has such a structure, when autoloading a roll of photographic paper, when the pulse motor 2, which is the easel mask driving power source, is rotated clockwise, the rotation of the pulse motor 2 is controlled. The racks 5, 5, which are in mesh with the pinion 4 which is integral with the shaft, are inserted into the respective long grooves 3 inward in the figure.
a, 3a, and then each slide pin rod bearing 5a, which is naturally integral with the rack 5, 5,
Each slide pin rod 10 supported on 5a,
10' also slide inward at the same time, so that each slide pin rod 10,
Similarly, each slide plate 7, 7' integrated with 10' is moved inwardly through the long grooves 8a, 8a' of the fixed plates 8, 8'.
That is, it slides in the direction of closing the hole of the easel mask 6, and at this time, the paper bridges 11, which are paper guide members, are moved in conjunction with this.
11' is the front part of the slide plate 7 where the photographic roll paper is introduced;
The slide plate 7' protrudes from the rear of the photographic paper roll and serves as a guide to form a traveling path for the photographic paper roll, so that the photographic paper can run smoothly and effortlessly during automatic loading of the photographic roll paper. It will definitely be done.

In addition, when the leading end of the roll of photographic paper reaches the inside of the winding cassette and the printing process is performed after autoloading is completed, the easel mask driving power source When the pulse motor 2 is rotated counterclockwise,
The racks 5, 5, which are in mesh with the pinion 4, which is integral with the rotating shaft of the pulse motor 2, slide outward in the figure through the long grooves 3a, 3a, and then,
Each slide pin rod bearing 5 integral with the racks 5, 5
Each slide pin rod 1 supported on a, 5a
Since the slide pin rods 10, 10' also slide outward at the same time, the slide pin rods 10, 1
Similarly, each slide plate 7, 7' integrated with 0'
The fixed plates 8, 8' slide outward through the long grooves 8a, 8a', that is, in the direction in which the opening of the easel mask 6 is opened and exposed. Although the paper bridges 11 and 11', which are guide members, also operate, they are configured to protrude downward and retreat by means of a link mechanism.

At this time, it is of course possible to control the number of revolutions of the pulse motor 2 to adjust the sliding amount of the slide plates 7, 7' so as to match the desired longitudinal print size.

Further, in this embodiment, a rack is used as a means for transmitting the driving force from the driving force source, but the means for transmitting the driving force is of course not limited to this, and instead of the rack. For example, a structure using a belt, wire, etc. is completely acceptable.

In addition, in this example, a total of two paper guide members (paper bridges) were installed so as to be interlocked with two slide plates, which are members for adjusting the printing size in the longitudinal direction of the easel mask. Although the structure has been described, the structure is not limited to this, and depending on the size of the easel mask, the paper guide member may be provided at least only on the introduction side slide plate so as to interlock with the paper guide member. Even in that case, the desired effect as a guide for the roll of photographic paper can be sufficiently achieved.

Moreover, the shape of the paper bridge, which is a paper guide member, does not have to have a planar guide surface.
For example, it may have a structure that partially protrudes.

As explained above, the present invention closes the opening of the easel mask with two slide plates during automatic loading of roll photographic paper, and at least the introduction side slide of the two slide plates. It has a completely new structure in which a guide member that protrudes and serves as a guide is provided at the front of the introduction side slide plate in the direction in which the rolled photographic paper is introduced, and is more compact than the conventional one. Another feature is that it is a functionally excellent easel mask for autoloading.
