Abstract

PURPOSE:To use a negative mask for plural kinds of negative films different in picture size by releasing the fixed relation of the negative mask mounter on a printer, and changing only the position of an opening part for exposing and printing. CONSTITUTION:Negative film rollers 111-114 are driven and a negative film F135 is carried. When a notch formed in each picture at a prescribed interval along on side edge of the negative film F135 reaches the surface of a small hole 1358, mark detecting light is detected by a photodetector 13510, the photodetecting signal is carried to each operation member driving signal generating circuit. Consequently, the negative film carrying rollers 111-114 are stopped, a pressing member C is driven, an electromagnet 30 is excited, a surface part 36 to be adsorbed of a pressing plate depressing plate 35 is adsorbed, and a thin plate-like negative film pressing plate 261 of a negative film pressing pressure plate 1352 on a negative film selecting and guiding member B is depressed against a spring 291 by a pressure plate depressing arm plate 37 against a spring 38, so that the negative film F135 is fixed on an exposing and printing position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved negative mask that can be used with several types of negative films having different screen sizes.

As is well known, one of the printer accessories is called a negative mask or negative carrier.
Negative film (hereinafter simply referred to as negative or film) is used to attach it to a predetermined location on the printer, and these are generally exclusive to each type of printer. Various film screen sizes (hereinafter simply referred to as sizes)
It was exclusive.

Therefore, when printing, even if the same printer is used, unexpected problems such as replacing each negative film with a different screen size with a negative mask that matches the screen size of the negative film and readjusting it are necessary. Despite the inconvenience and difficulty of requiring time and effort, which has made printing work a one-sided task, it is indispensable in this kind of work, and here it is one of the most important features in this kind of industry. The idea that there was something special had become a preconceived notion.

In view of the above-mentioned circumstances, the present invention provides a negative mask with guide paths for each of several types of negative films having different screen sizes.
Several strips are formed parallel to each other at intervals from one side to the other, and on the bottom wall that guides the flat surface of the negative film in each guide path, there are exposed and printed strips that match the screen size of the negative film to be guided. A device stand is provided with openings for use in the valley exposure printing, and an opening for passage of light is provided on the openings for the valley exposure printing. A cover plate provided with guide holes for vertical movement of the negative film holding plate on both sides of the passage openings on the negative side and the other side of the device stand, and each passage provided in the cover plate. Supports for passing through guide holes for vertical movement of the opposing negative film holding plates provided on both sides of the opening are respectively erected and tightened, and each exposure and printing of each guide path in the holder is For exposure printing, the openings for the light passages, which are approximately the same shape as the openings, are opened, and a negative film holding plate is attached to each guide path, and each negative film is attached to each guide path. The biasing member is interposed between the lower surface of the flange-shaped head of the upper end of each support plate of the holding plate and the upper surface of the cover plate, and normally lifts each negative film holding plate above each of the guide paths. By doing so, as with conventional negative masks of this kind, when printing work etc. using this, the work is stopped each time the type of negative film or the screen size of the negative film changes, and the screen of the negative film is changed. Instead of having to go through the trouble of replacing the negative mask with one that matches the size and readjusting it, you can simply release the fixed relationship of the negative mask installed in the printer and shift it slightly, and then expose and print it using the opening of the printer. This enables the provision of a negative mask that can be done by simply changing the position, breaking the preconceptions of conventional negative masks of this kind.Hereinafter, the screen sizes according to the present invention A negative mask that has been improved so that it can be used for several types of negative films is incorporated into a negative carrier, and used as a negative film selection guide member that is equipped with a separate guide path for each negative film to guide the 135 film and 126 film. The present invention will now be explained in detail by means of illustrative embodiments as provided.

The small holes 135.notches are formed along one side edge of the negative film F1 for each screen at predetermined intervals.
, b or 135'8, the label detection light is transmitted to the light receiving element 135□. Or it is received at 135'zo,
The light reception signal from the light receiving element 1351o or 135'1o is sent to the signal transmitting circuit for driving the 6 actuating members, and at the same time, the negative film feed rollers 111, 112.11° and 1111 are stopped, and the suppressing member C is driven. The electromagnet 30 is energized to attract the attracted surface portion 36 of the pressure plate pressing plate 35, and the pressure plate is pressed down against the springs 3, 8, and 38 by the arm plates 37, 37 to press the negative film in the negative film selection guide member B. The thin negative film holding plate 261 of the pressure plate 1352 is pushed down against its springs 29□, 291, and the negative film F1-5 is identified at the exposure and printing position.

In this way, the screen of the negative film F155 is exposed and printed in the negative film guide path 1351 at the opening part 13.
55, that is, at the printing position, signals from the signal transmission circuit for driving each actuating member are transmitted to each member for printing, and after the exposure and printing operation is completed, the negative film feed rollers 111, 112, 11. and 11. is driven again, and the above operation is automatically repeated until the negative film Fl 5 is completely transferred.

Each of the above operations is performed using negative film F12G+FI.
The same procedure is applied to LO, and negative film F
