路Ｃ中に送出される。 Recently, in order to increase the copying capacity of copying machines, a paper feeding device as shown in FIG. 1 is sometimes used in copying machines. That is, this paper feeding device is built into the stand B of the main body A of the copying machine, and the recording paper X is placed on a pallet 3 in a box-shaped vessel 2 placed on the base 1. be accommodated. A paper feed unit 4 is located above the base 1,
The recording paper X is lifted up as a pallet by a lift 5, and fed one by one into a paper feed path C by a paper feed unit 4.

する場合があつた。 By the way, in such a paper feeding device, a shearing force F directed toward the left in the drawing acts on the recording paper X when it is fed by the paper feeding unit 4, so that the pallet 3 is deflected by this shearing force F. There is a tendency. For this reason, a photoelectric detector that detects the presence or absence of recording paper
If the window 3A of the pallet 3 is removed from the optical axis of S 1 and S 2 , the pallet 3 may be fed by the paper feed unit 4 without stopping the lift 5, or the pallet 3 may be
In some cases, this caused interference with the fixed parts of the equipment and other devices, leading to malfunctions.
本考案は、以上に述べたようなパレツトの水平
面内での移動を防止した給紙装置を提案するもの
であつて、リフトまたはベツセルに係止面を設

抑止させることを特徴としている。 The present invention proposes a paper feeding device that prevents the movement of pallets in a horizontal plane as described above, in which a locking surface is provided on the lift or vessel, and a locking piece protruding from the pallet is provided with a locking surface. It is characterized by being restrained by the same locking surface.
以下、第２図〜第４図について本考案を具体化
するための実施例を説明する。 Embodiments for embodying the present invention will be described below with reference to FIGS. 2 to 4.

るから、従来例で述べたような障害は起らない。 FIG. 2 shows a first embodiment of the present invention. In this embodiment, cut and raised protrusions 6 are folded at right angles in the center of the pallet 3 located on the lift 5. It is engaged with the rear surface 5a, that is, the locking surface. Therefore, according to the present invention, even if a force F in the direction of the arrow is applied to the pallet 3, the pallet 3 is prevented from moving by the rear surface 5a of the lift 5, so that the trouble described in the conventional example does not occur. do not have.

阻止することができる。 FIG. 3 shows a second embodiment of the present invention. In this embodiment, a locking surface 7 is formed on the inner surface of the recess formed in the side wall 2a of the vessel 2. A protrusion 6A protruding from the side of 3 is locked. Therefore, in this example as well, pallet 3 is prevented from moving in the direction of the arrow.
Malfunction of the lift 5 caused by movement of the pallet 3 in a horizontal plane and interference between the pallet 3 and other members can be prevented.
第４図は本考案の第３実施例であり、この実施
例の場合、パレツト３はベツセル２の後壁２ｂに
よつて水平面内での移動を阻止される。 FIG. 4 shows a third embodiment of the present invention, in which the pallet 3 is prevented from moving in a horizontal plane by the rear wall 2b of the vessel 2.

になる。 That is, the outer surface of the rear wall 2b divided into two forms a locking surface 7A for restraining the pallet 3, and a pair of hooks or protrusions 6B formed at the rear of the pallet 3 are provided on these locking surfaces 7A. It's hooked up. With such a configuration, movement of the pallet 3 in the horizontal plane is also prevented as in the case of FIG. 3.

がある。 As is clear from the above description, according to the present invention, with a simple configuration, inconveniences caused by pallets moving in a horizontal plane, such as lift malfunctions and obstacles caused by interference between pallets and other members, can be eliminated. Can be done. In particular, in the embodiment shown in Fig. 2, a protrusion 6 is provided below the pallet 3, and is directly locked at the end of the lift 5 at the same position even when moving up and down, so that the pallet 3 and the lift 5 can move together. This structure has the effect that the lift 5 can rise and fall smoothly without the protrusions of the pallet 3 sliding on other locking surfaces.
