Description

[Detailed Description of the Invention] The present invention is an easel mask used in a photographic printer device, and in particular has a mechanism for attaching and detaching the easel mask to the easel body, which allows adjustment of print size in the longitudinal direction by means of two slide members. This relates to an improvement, and when attaching and detaching from the easel body due to changing the roll of photographic paper, etc., it is connected to the drive mechanism with one touch when attached, and the slide member is locked when removed.

Conventionally, when attaching and detaching this type of easel mask to the easel body, it was very difficult to attach and detach it from the easel body, as it was necessary to connect each engagement part to the drive mechanism of the easel body. This method requires time and effort, and also has the disadvantage that when removed, the slide member becomes free and is troublesome to handle. This was even more noticeable in a structure in which a paper guide member was provided as a guide, interlocking with the introduction-side slide member, and protruding from the front part of the introduction-side slide member in the direction in which the photographic paper was introduced.

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 a preferred embodiment thereof with reference to the accompanying drawings.

In the figure, 1 is the easel main body, 2 and 2 are easel rear support pins installed on the back plate 1a of the easel main body 1, and 3 is an easel mask positioning pin that projects vertically from the top of the front plate 1b of the easel main body 1. Pin 4 is a pin for lifting a slide plate shaft lock member 16, which will be described later, and which projects horizontally inward from the back surface of the front plate 1b of the easel main body 1.

5 and 5' are both side plates 1c of the easel main body 1,
The easel width guide is supported so as to be movable in the axial direction with respect to the guide rods 6 and 6' installed between 1c, and the easel width guides 5 and 5' are easel mask driving force sources. Since the guide rods 6 and 8 are connected via pins 5a and 5a', respectively, to wires 9 set between wire pulleys 8 and 8 that are linked to the rotating shaft 7 of the pulse motor, the guide rods 6 and 6', and at that time the easel width guide 5,
Slide plate shafts 14, 14' connected to two slide members 11, 11' for adjusting the mask size of the easel mask 10, which will be described later, are supported by the supporting parts 5b, 5b' of the mask 5', respectively. Furthermore, an appropriate mask size can be determined in conjunction with the movement of the easel width guides 5, 5'.

Reference numeral 10 designates an easel mask section, and its structure will be explained in detail. Reference numerals 11 and 11' are two slide plates for adjusting the easel mask size in the longitudinal direction, and respectively determining the easel mask size in the width direction. The two fixed plates 12, 1
2' by using long grooves 12a, 12a'(12a' is not shown) so as to be slidable.

Reference numeral 12b is a positioning hole in which the easel mask positioning pin 3 formed on the fixing plate 12' engages.

Fixed plates 13 and 13' are fixed to both ends of the bottom surfaces of the fixed plates 12 and 12', respectively.

14, 14' are support levers 11a, 11 fixed to the bottom surfaces of the slide plates 11, 11', respectively.
This is a slide plate shaft rotatably supported by a'.

Further, reference numeral 15 designates a paper guide member which is installed so as to protrude from the front part of the slide plate 11' on the roll photographic paper introduction side in the roll photographic paper introduction direction of the two slide plates mentioned above so as to serve as a guide.

16 is integrated with a pin 16a that is inserted into a hole (not shown) formed on the fixing plate 12' and is prevented from falling off in the direction of gravity by a retainer 16b installed on the top of the pin 16a. This is a slide plate shaft lock member having U-shaped engaging portions 16c, 16c at both ends thereof, which engage with the slide plate shafts 14, 14', respectively, and 17 is a slide plate shaft lock member. This is a locking coil spring interposed between the member 16 and the fixed plate 12'.

Since the present invention has such a structure, when attaching and detaching the easel mask section 10 to the easel body 1 in order to change the roll photographic paper, etc., the easel mask section 10 is first removed from the easel body 1. When removed, as shown in Figure 2,
Slide plate shafts 14 and 14', which are connected to slide plate members 11 and 11' for adjusting the easel mask size in the longitudinal direction, are pushed downward by the tension of the locking coil spring 17. Since it is locked by the U-shaped engaging portions 16c and 16c formed at both ends of the member 16, the two slide plates 11 and 11' are locked in their central positions, that is, with the easel mask closed. It is very easy to handle.

Also, when attaching this easel mask section 10 to the easel main body 1, the positioning hole 12b formed on the fixing plate 12' of the easel mask is used.
to the easel mask positioning pins vertically protruding from the top of the front plate 1b of the easel main body 1, and engage the slide plate shafts 14, 14' with the support parts 5b, 5b' of the easel width guides 5, 5'. If you install it so that it is forced, (at this time easel mask 1
0 is supported by easel rear support pins 2, 2. ) As shown in Figure 3,
The slide plate shaft lock member 16 comes into contact with the slide plate shaft lock member lifting pin 4 that projects horizontally inward on the back surface of the front plate 1b of the easel main body 1, and as a result, the slide plate shaft lock member 16 is locked. The slide plate shaft 1 is pushed up against the tension of the coil spring 17, and the slide plate shaft 1
4, 14' and the slide plate shaft locking member 16 are released, and the slide plates 11, 11' become free.

As explained above, according to the present invention, in an easel mask used in a photographic printer device, and in particular in an easel mask in which the print size in the longitudinal direction can be adjusted by two slide members, the roll When attaching and detaching from the easel body due to changes in photographic paper, etc., when attached, simply place it on the easel body and it will automatically connect with the drive mechanism with one touch, and when removed from the easel body, the slide member will be locked. In this way, an easy-to-handle easel mask attachment/detachment mechanism is obtained.
