れて行く。In the paper feeding device of the present invention configured as described above, when the paper feeding cassette (2) is set in the paper feeding section of the copying machine main body (1), as shown in FIGS. 6(a) and (b). This is done by inserting the paper feed port side of the paper feed cassette (2) into the copying machine main body (1). ) collides with the retaining convex portion (18) of the sealing member (17), so that the sealing member (17) resists the coil spring (19) as the insertion operation is performed, causing the sealing member (17) to move as shown in FIG. 6(b).
) (2) Rotate clockwise to open the paper feed slot (5). Therefore, the paper feed cassette (2) is rotated clockwise to open the paper feed slot (5).
5) is set in an open state, and at this time, the electrode (15
) is connected to the electrode on the copying machine main body side, so the motor, (1
1,) is set. In this state, when you press the copy start button (not shown) provided on the copying machine main body (1), the motor (11) is driven at a predetermined timing, the power is transmitted to the paper feed roller (8), and the copy start button (not shown) is pressed. Due to the rotation of the paper roller (8), the paper (20) is separated by the paper handling member (A).
The paper is sorted one by one and fed through the open paper feed slot (5).

発明の技術思想に含まれるものである。In the above embodiment, the sealing member (17) opens upward and outward, but it does not necessarily have to be this type. For example, as shown in FIG. 7 (2. Alternatively, as shown in FIG. 8, the pin (16), which is the rotation fulcrum of the sealing member (17b), may be rotated inward from the paper feeding force center (2). Alternatively, the sealing member (17b) may be opened downward and outward, and both of these are included in the technical concept of the present invention.

利用価値は顕著である。As described above, according to the paper feeding device of the present invention, the paper feeding member is disposed inside the cassette body formed in a sealed shape, and the paper stored in the paper feeding member is transferred to the paper feeding port. (=The paper feed slot has an openable and closable seal that can be opened by engaging with the paper feed unit when the paper feed cassette is inserted into the paper feed unit of a copying machine, etc.) Because the parts are pivoted,
The paper is not exposed to the outside air during either loading or storage, which solves problems such as poor transfer due to moisture absorption and paper wrinkles. The member is pressed in the direction of always closing the paper feed port by means of the elastic means (2).
It is not necessary to open and close the cassette lid each time when setting paper feed or storing paper, and excellent effects such as speedy setting and replacement work can be obtained, so its utility value is remarkable.
