The film guide 50 is fixed in the box 40, guides the film 37, and stores it in a spiral shape. The width of the film guide 50 is narrower than that of the film 37 so that the film guide 50 can be easily picked up by fingers when the film 37 rolled into the box 40 is taken out.
The leading end 50a of the film guide 50 is raised so as to form the entrance of the film 37. Further, as the film guide 50, in order to prevent the film 37 from being scratched, a plastic or a metal plate to which Teflon or the like is attached is used.

The weight 51 is made of a heavy material such as iron, and is fixed to the bottom surface 440 of the box 40. When the table 16 is made of metal, it is convenient to use a permanent magnet instead of the weight 51.

As shown in FIG. 2, the developed film 37 is set between the under mask 17 and the upper mask 18. At the time of baking, the upper mask 18 is attracted by a magnet (not shown) to press the film 37 onto the under mask 17, and when the baking is completed, the upper mask 17 is separated from the under mask 18. The operator prints with one hand while holding the part of the film to be printed in a rolled state. And 1
After the frame printing is completed, the film 37 is manually transferred by one frame and a new frame is set at the printing position of the negative carrier 19.

The frame for which printing has been completed is sent toward the film container 20 and enters the inside through the film insertion port 411. The film 37 that has entered the film container 20 is guided by the film guide 50 and is wound into a spiral shape. In general, the film 37 has a curling curl on the emulsion surface side while being stored in the cartridge, so that when the film 37 is guided by the film guide 50, the film 37 easily curls in a spiral shape. When one or more films 37 are stored, a new empty film storage device is placed on the table 16. When accommodating a plurality of films 37, the leading edge of the film to be inserted next is set so as to be outside the trailing edge of the already inserted film.

The film 37 stored in the film storage device 20 is
Although it will be taken out later, at this time, the portion of the film 37 protruding from the film guide 50 can be taken out from the front of the box 40 in a rolled state by pinching it with a finger.

The same members as those in FIG. 2 are designated by the same reference numerals.
In this upright type, the white light source 23 is arranged above,
The printing paper 30 is arranged below. The film 37 is
Since the emulsion side is set on the negative carrier 19, it is necessary to set the film container 20 upside down from that of FIG. Film storage device 20
Has a permanent magnet 53 attached to the bottom of the box 40,
The permanent magnet 53 is attached to the side surface of the table 16.
When a weight is provided instead of the permanent magnet 53, a bracket may be attached to the table 16 and the film container 20 may be placed thereon.

FIG. 6 shows a negative carrier capable of switching between full size and half size. A turntable 60 is arranged substantially in the center of a table (not shown). An under mask 61 is attached on the turntable 60, and the first over mask 62 and the second over mask 6 are placed on the under mask 61.
3 and 3 are provided so as to be movable in the arrow direction. This first
And the second over masks 62, 63 include arms 64,
65 are fixed to each. Also, this arm 6
Reference numerals 4 and 65 are screwed onto feed screw shafts 68 and 69 having bevel gears 66 and 67 attached to one ends thereof. The bevel gears 66 and 67 are arranged so as to sandwich a bevel gear 71 fixed to the tip of a shaft 70. A pinion 72 is fixed to the rear end of the shaft 70, and the pinion 72 meshes with a fixed crown gear 73.

For full-size printing, the film storage container 20 is set at the position indicated by the solid line, and the baked film is inserted into the film storage container 20 and rolled. When half-size printing is performed, the turntable 60 is rotated 90 degrees in the arrow direction. When the turntable 60 rotates, the pinion 72 moves while rotating on the crown gear 73, so that the bevel gear 71 rotates. Since the rotation of the bevel gear 71 is transmitted to the feed screw shafts 68 and 69, the first over mask 62 and the second over mask 63
And move toward each other, as shown by the arrow,
The screen size is adjusted to half of the full size. In this half-size printing, the film 37 is inserted from the front side, and the film 37 is sent toward the inner side where the photo developing unit housing (not shown) is located. Therefore, in this half-size printing, the film storage container 20 is arranged on the back side indicated by the chain double-dashed line. In this case, turntable 60
The film storage device 20 is removably attached via the mounting bracket 60a. As a result, the film storage device 2

The bottom surface of the bottom 75a of the film container 75 that contacts the table is substantially horizontal, and most of the front surface and the upper left portion are open. Two ridges 75b are formed on the inner surface of the film container 75, and the contact area of the film is reduced so that the film can be smoothly guided. Further, a pressing portion 75c whose lower end is expanded outward is formed on the front surface of the film container 75, so that when the film is pushed in at a slight angle, the leading end portion thereof is guided so that the film is properly rounded. I have to. A hole 75d is formed on the rear surface of the film container 75, and a finger is inserted when pushing out the rolled film. This is effective in preventing the film from becoming bamboo shoot-like when the film is taken out. The reference numeral 75e is a film insertion opening.

〔The invention's effect〕

As described above in detail, according to the present invention, since the film storage device is provided on the side of the negative carrier and on the downstream side of the film transfer, the baked film can be stored in a good appearance. Therefore, unlike the conventional photoprinting apparatus, since the baked film is not left hanging on the table, the baking work is easy and the film is not likely to be scratched. In addition, it is formed in an arc shape, a film inlet is formed between one end and the other end, and a film guide for storing a baked film in a rolled state and one side edge of the rolled film are formed. Since the first side edge guide for guiding and the second side edge guide for guiding the other side edge portion of the film are provided, simply by feeding the film on the negative carrier after baking,
The baked part goes into the film container, and the film is smoothly rolled in the film container by the guide by the film guide and the winding of the film itself, so just by performing the same baking work as before. The film can be stored easily.

Further, since the upper part of the film guide on the film entrance side is cut out so that the width is narrower than the film in the film width direction, the film entrance side is formed by cutting out the film entrance side part of the second side edge guide. The film rolled into the film container can be easily pinched with your fingers, and the film can be taken out easily.

Further, since the film is guided by the remaining film guide portion, the film can be smoothly stored in a state in which it is rolled into the storage container.

Also, since the film storage device is detachably attached to the turntable on the downstream side of the film transfer, which is located next to the negative carrier, the film is fed vertically like a film recording half-size frames, and the film travel direction is increased. Even when the apparatus body or the like is located in the position, the film tip does not hit the apparatus body or the like, and the film can be rolled and stored in the film storage container in the same manner as the lateral film feed.
