Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a film suitable for a photographic film reader which can use an APS (registered trademark) photographic film system for use of a cartridge holder. It relates to a cartridge holder. 2. Description of the Related Art In a photographic film reader, about six frames of photographic film pieces which are separated in a development stage are set on a carrier and loaded into an opening of a main body of the reader.
The image data of the photographic film is converted into an electric signal while the carrier is relatively scanned with respect to the reading means. [0003] Recently, a new photographic system APS that can be stored in a cartridge even after the development processing has been performed.
(Registered trademark) is beginning to spread. In this system, the photographic film used is not only different in size from normal photographic film but also is always handled in a cartridge, so that it is impossible to load the reading device via a carrier. . To cope with this problem, a holder having a cartridge accommodating portion for accommodating a cartridge of APS (registered trademark) photographic film and a window for exposing the photographic film for reading is prepared. At the stage of storage, close the cover and turn the cover knob to fix the cover to the holder body, and in conjunction with the rotation of this knob, open the light shielding cover of the cartridge,
It is configured such that the film can be loaded into the reading device in a state where the film can be fed. [0005] However, since the size of the film cartridge itself is extremely small and there is some play or play, the rotation of the knob does not lead to the opening of the light shielding cover of the film cartridge. Therefore, since the cover can be locked, the film is fed out in a state where the light-shielding lid is closed, which causes a problem that the film is damaged. The present invention has been made in view of such a problem, and an object of the present invention is to provide a holder of a photographic film reading device capable of externally checking the opening and closing of a light shielding cover of a film cartridge. is there. In order to solve such a problem, the present invention provides a cartridge accommodating portion which can be opened and closed by a lid, a film exposure window for exposing a film drawn from the cartridge, and provided on the lid
Comprising a driving rotary members that opens and closes <br/> the shielding cover of the cartridge in association with the rotation of the knob, and a connected display plate via the link mechanism to said drive member, said link mechanism, the Of the lid
A knob moves the light-shielding lid from the locked position to the open position.
Engagement is performed at the stage where the knob is turned by a certain amount, and the rotation of the knob is transmitted in an enlarged manner.
The lid knob is set to the open position.
Moves the display board to a position where it can be viewed when turned
It is configured to be. When the driving member of the light-shielding lid is rotated to a position where the light-shielding lid can be opened by the rotation of the knob, the display plate is moved to a position where it can be visually recognized from the outside. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a first embodiment of the present invention. FIGS. 1 and 2 show an embodiment of the present invention. A holder 1 has a cartridge accommodating portion 4 which can be opened and closed by a lid 3 on one side surface 2 and a film pulled out from the cartridge on an upper surface 5. A film exposure window 6 for exposing the upper surface 5 is formed.
And a guide member 8 having a groove 7 that engages with the guide member of the reading device so as to extend from both sides to the guide member. The cover 3 has a knob 11 which rotates between a lock position and an open position by a center shaft 10. The cover 3 is fixed to the main body on the film storage side, and the light shielding cover of the cartridge 30 is on the surface 9. An engagement plate 12 is also provided, which also serves as a rotating member of a driving member 14 that opens and closes 31. A surface 9 facing the surface 2 on which the lid 3 is provided
A display window 13 for exposing a display plate 22 to be described later is formed in the vicinity of the film exposure window 6 and a knob 1 of the lid 3.
When the light-shielding lid 31 of the cartridge 30 is rotated to the open state by the rotation of the display 1, the display plate 22 can be checked from the outside. FIG. 3 shows an embodiment of a display device. A pin 15 is formed on a driving member 14 for opening and closing a light-shielding lid 31 of a film cartridge 30, and a slot 16 is formed at one end. The “L” -shaped link 17 is engaged. An engagement portion 18 is formed at the other end of the link 17, and a cam 20 having a pin 19 abutting on the engagement portion 18 is provided.
Is pivoted. The cam 20 is provided on the arm 2 reaching the display window 13.
1 is formed to constitute a second link mechanism, and a light-shielding lid closed display area 22a and a light-shielding lid open display area 22b are provided at the ends.
And the display panel 22 is fixed.
The second light-shielding cover closed display area 22a is urged by a spring 23 (FIG. 4) so as to face the window 13. Reference numeral 24 in the drawing indicates a member that regulates the movement range of the arm 21. In this embodiment, a light-shielding lid 31 is loaded into the cartridge accommodating portion 4 toward the film exposure window 6 and the lid 3 is closed. Engage with the drive shaft. In this state, since the knob 11 is at the “OPEN” position, the light-shielding cover rotating shaft is not rotated, and the engaging portion 18 of the link is far away from the pin 19 of the cam 20, and the arm 21
Is displaced to one side by the urging force of the spring 23,
The second light-shielding lid closed display area 22 a is located in the display window 13. When the knob 11 is turned to the “LOCK” position, the engagement plate 12 is turned following the turning of the knob 11. The driving member 14 of the light-shielding lid 31 rotates in conjunction with the rotation of the engagement plate 12 to rotate the light-shielding lid 31, and the tip of the link 17 contacts the pin 19 of the cam 20 during the rotation.
In this state, the light-shielding lid closed display area 22a of the display plate 22 still faces the window 13. Therefore, even if the lid 3 is locked by the holder 1, if the display of the display window 13 is confirmed, the cartridge 30 can be removed. It can be determined that the light shielding cover 31 is not yet set in the open state. When the knob 11 is further rotated to a position where the light shielding lid 31 is securely opened, the driving member 14 of the light shielding lid 31 is rotated.
Pivots to securely set the light blocking cover 31 to the open position. The rotation of the knob 11 is transmitted to the cam 20 by the link 17 and rotates the arm 21 in the direction of arrow A against the spring 23. The rotation of the driving member 14 of the light-shielding lid 31 is enlarged by the two-stage link mechanism, and the light-shielding lid open display area 22b of the display panel 22 is opposed to the display window 13 (FIG. 3B).
It is thereby the cartridge 30 of the film feeding
You can see that it is possible . As described above, according to the present invention ,
The light-shielding lid of the cartridge was securely opened by the drive member
In this case, since the display plate can be visually recognized, it is possible to prevent the light-shielding lid from being loaded in the reading device when the light-shielding lid is not opened.
