As shown, both side plates 182, 182 have engaging elements 181, 181 protruding from their outer surfaces to be engaged and held in the adapter holding groove of the holder, and a curved bottom plate 183 installed between the both side plates. A pocket-shaped storage part 184 is formed to store a cartridge, and a spool protruding from one end plate of the cartridge is engaged and held on the inner surface of one side plate 182 of the pocket-shaped storage part 184. A cartridge holding groove 185 is formed to form a cartridge adapter 180, and a cartridge and a cartridge are exchangeably attached to the holder via the cartridge adapter 170 and the cartridge adapter 180, respectively.

(Problem that the invention aims to solve) However, in the case of conventional film feeding devices for automatic photo film processing machines, dedicated cartridge adapters and cartridge adapters are required for each cartridge and cartridge of different sizes. Therefore, the number of adapters that must be prepared increases, which is not only uneconomical, but also requires time and effort to store and replace adapters.

The present invention has been developed in view of the above-mentioned circumstances, and makes it possible to replaceably attach a cartridge and a cartridge having similar external dimensions to a holder in a film insertion box via a common adapter. The object of the present invention is to provide a film feeding device for an automatic photographic film developing machine.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a holder in which adapter holding grooves are formed in both sides of the holder body, which are installed upright on both sides of the holder body. Both side plates are movably attached to a guide rod provided in a film feeding direction in a film insertion box of a developing machine, and have engaging elements protruding from outer surfaces thereof to be engaged and held in adapter holding grooves of the holder. A pocket-shaped storage section is formed by the curved bottom plate installed between the side plates, and the pocket-shaped storage section is configured to accommodate both a cartridge and a cartridge having similar external dimensions. A cartridge holding groove is formed on the inner surface of the cartridge, in which the engaging elements protruding from both end plates of the cartridge are engaged and held, and a cartridge holding groove is formed on the inner surface of one of the side plates, and a cartridge holding groove is formed on the inner surface of one of the side plates. A common adapter is attached to the holder, and the cartridge holding groove, which engages and holds the cartridge spool, is shallower than the cartridge holding groove and communicates with the cartridge holding groove toward the bottom of the pocket-shaped storage section. Furthermore, the cartridge and cartridge are replaceably inserted into the shared adapter.

(Function) Since the present invention is configured as described above,
The cartridge or cartridge can be replaced by simply removing the cartridge or cartridge inserted into the common adapter attached to the holder and inserting a replacement one.

1 and 41, close the lid body 13, and hook the stopper 16, the cartridge ₇₀₁ is pressed by the pressing leaf spring 18, and the cartridge opening pins 19, 19 and the cartridge opening lever 43,
43, the film drawer portion 72 of the cartridge ₇₀₁ is opened, and the loading of the cartridge ₇₀₁ is completed. When loading the cartridge 80 in place of the cartridge ₇₀₁ , the shot leader is connected to the end of the film, and the cartridge opening levers 43, 43 are allowed to freely move. When loading of cartridge ₇₀₁ is completed,
The holder 30 is pressed against the stoppers 22, 22 by the biasing of the coil springs 23, 23, the upper blade 51 of the cutter 50 is raised to the raised position, and the micro switch 59 is open. Next, when the motor 57 with a speed reducer etc. is connected to a power source (not shown) and the feed roller 40 is started by the motor (not shown), the shot leader is sent out and connects the film feed port 17 and the automatic developing unit 1. The film is fed into the automatic developing unit 1 through a film insertion slot (not shown). Although not shown, the shot leader is conveyed by engaging the perforation provided in the shot leader with a conveying drive sprocket provided in the automatic developing unit 1. As a result, the film f is fed from the cartridge 70 ₁ into the automatic developing unit 1 .
Patrone 80 in place of the cartridge ₇₀₁
When the film f is loaded, when the end of the film appears from the cartridge 80 after the film f is fed out, the holder 30 is strongly pulled by the film f.
The switch actuator 37, which is installed at the front end of the holder 30, moves backward against the bias of the micro switch lever 5, and to the left in FIG.
9' is closed, the motor 57 with reducer starts,
By operating the upper blade 51 of the cutter 50 via the rotating shaft 58, the disc 56, the crank pin 55, the crank rod 54, and the connecting pin 53, the film f is cut at the film end.
The holder 30 is moved forward and back by the bias of the coil springs 23, 23, and the upper blade 5 of the cutter 50
1 returns to the upward position, and the motor 57 stops. Next, the lid 13 is opened and the empty cartridge 70 or cartridge 80 is removed from the holder 30. Thereafter, the above-mentioned operation is repeated, and if necessary, the cartridge 7 is
0 ₁ , 70 ₂ , the cartridge 80 is replaced and inserted into the common adapter 60.

(Effects of the Invention) As is clear from the above explanation, the present invention is designed to allow cartridges and patrones which have similar external dimensions to be interchangeably attached to a holder in a film insertion box via a common adapter, which results in the fact that only one adapter needs to be prepared, reducing the number of parts and making it more economical, and eliminating the need to store adapters and the trouble of replacing them, which were unavoidable with conventional film feed devices.
