When the rear end 16a (see j1 in FIG. 3) reaches the rear side of the integral 1 beyond the red mating surface 44b of the 1 thread mating protrusion 44,
This locking protrusion 44 is displaced in one direction by the action of the spring 39. In this way, the retaining protrusion 44 fits into the retaining hole 16. As a result, the cassette 3 can be attached to the four parts 16a of the retaining hole 16.
and the engaging portion 44b of the red 8 protrusion 44 come into contact with each other, and the cassette 3
is prevented from shifting to Isokyu's hand IJiJ side. cassette! Similarly, the cassette 4 attached to the A4 body 17 is also prevented from being placed in front of the unit 1 by the retaining protrusion 45 (6).

The cassettes 3 and 4 are attached to the cassette front body 17, and when the cassette oil supply body 17 is being pulled out, it is moved to the rear side of the body 1 by a motor 26. Paper can be fed from the cassette 3 by moving the cassette mounting body 17 as shown by the solid line in FIG. 6 so that the paper cassette 3 is placed directly below the paper feed row 213. .

When paper is fed from the cassette 4, the cassette front body 17 is moved to the rear side of the machine body 1 by the motor 26. The cassette mount 17 thus reaches the position indicated by reference numeral 60 in FIG. In this situation, the cassette 4 is located directly below the paper feed roller 13. Paper is fed from the cassette 4 by driving the paper feed roller 13.

In addition, the paper feed row 213f'i, a plane parallel to the -diameter line [&
I 13 atl- has. In a seat where paper feeding is not performed, this semicircular enclosure 13a faces downward. This prevents the cassettes 3 and 4 from colliding with the paper feed roller 13, making it convenient to arrange the cassettes 3 and 4 directly below the paper feed roller 13.

When removing the cassettes 3 and 4 from the cassette loading body 17, the cassette loading body 17t may be moved forward by the motor 26 to the front of the body 1, or may be inserted into the body 1 as is. There, control knob 4

It resists the spring force of 9 and manages to dodge it. This allows the connecting S
t4'43 and 1-8-protrusion 44.45 are tilted upward as shown in Figure 4510 (2), and the retaining protrusion 44.
45 sinks downward from the extension hole 58.59. As a result, the cassettes 3 and 4 can be pulled out along the red clay protrusions 22 and 23 in an arbitrary manner. When this cassette 3 is pulled out to the front side of the cassette 3, the 1 part of the cassette 3 no longer comes into contact with the retaining protrusion 34, and the lever 32 is thereby angularly displaced around the bottle 31 to the counterclockwise force as shown in FIG. do. Therefore, the stopper 33I-J acts downward from the insertion hole 35. As a result, it becomes i3J ability to draw out the hand SiJ play of the cassette 3 warehouse machine l.

The cassette device body 17 has a chicken 6 in order to detect the position 1d.
As is obvious, the Mizuku magnetic plate 71 was inserted into the cassette device body 1.

In combination with 'A'A Kaidushiko 72 and 73, the greeting end position of the cassette mounting body 17 is detected 11j, and thereby the 1-dakuri II all of the 7-ri 26 is performed.

As an example of the book's Noh performance, I put one piece of Rouseki on cassettes 3 and 4 to display the tweezers of the rice paper stored in those cassettes 3 and 4. This right-hand piece may be detected by a magnetic element provided on the cassette mounting body 17. The numbers of paper sheets stored in these cassettes 3 and 4 are displayed by means of a display provided on the operation panel of the cassette 1,
Therefore, the cassettes 3 and 4 can be selected for copy paper.

FIG. 11 is a flat curved view corresponding to FIG. 5 of another embodiment of "Kienori", and is a survey view of the cassette mounting body 17 seen from the paper feeding direction of FIG. 11-L in FIG. be.

This example is similar to the mer example and corresponds to 1115
Add a reference gradient of 01 times per minute. It should be noted that the cassettes 3 and 4 can be displayed on the cassette front piece 17 along the paper feeding direction 11. A locking protrusion 50.51 is formed on the connecting portion +)U43. This engagement 50I''i,
As shown in FIG. 13, an inclined surface 50a inclined upward along the paper feeding direction 19-1, and
The fourth indicator thI50b is connected to a and extends downward on the downstream side in the paper feeding direction 11. Cassette 3 is paper feed direction 11
The bottom 3 of the cassette 3 is
b pushes down the inclined surface 50a against the spring force of the spring 39. In the case where the cassette 3 is properly attached to the cassette mounting body 17, the retaining protrusion 50 engages with the retaining hole 16 (see FIG. 3) formed in the cassette 3, and the retaining protrusion 50 engages with the retaining hole 16 (see FIG. 3). Direction 1

As a result, the cassette 3 is moved from the cassette device body 17 to the upper tfiL side of the sheet feeding direction 11, that is, the 11th
This prevents it from falling away from the diagram. Such a groove structure also applies to the cassette 4.

In order to determine the position of the cassettes 3 and 4 (!L), not only the position UJLθ width 19 and 29, but also the positioning plates 61 and 62, 63 are moved in the paper feeding direction ii and 11.
It will be erected on top of Chikaratamaya 918.

To remove the cassette 3 from the cassette 11 body 17, push the operation knob 40 downward.
