Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medium feeding gate having a gate body that opens a conveyance path by rotation.
For example, at the confluence of the first transport path and the second transport path connected to this first transport path, there is a gate main body arranged so as to block the second transport path, and the medium is sent from the second transport path side. The present invention relates to a medium feeding gate in which the gate main body is pushed by the medium and rotates so as to open the second transporting path to feed the medium into the first transporting path.

The stopper 28 regulates the downward movement of the locking portion 25.

The guide cover 50 is provided with an upper guide 55, and the upper guide 55 is provided with a large notch for accommodating the conveying roller 40, as shown in FIG. Further, as can be inferred from FIG. 16, a concave portion 55A into which the gate tooth 21A is inserted is provided on the lower surface of the medium feeding gate 20 which faces each gate tooth 21A.

The handle 56 in FIG. 9 is used when the drive roller 40A of the conveying roller 40 is manually rotated. Next, a procedure for assembling the medium feeding gate 20 to the guide cover 50 will be described with reference to FIGS. Here, FIG. 18 is an explanatory diagram at the start of assembly, and FIG. 19 is an explanatory diagram after assembly. First, with the medium feeding gate 20 vertically, the shaft portions 22, 23 are inserted into the slits 51A, 52A, 53A of the side plates 51, 52 and the middle plate 53 of the guide cover 50 from below.
Plug in. The shaft portions 22, 23 have holes 51B, 52B, 53
When it reaches B, the medium feeding gate 20 is rotated in the clockwise direction in FIG. 18 around the shaft portions 22 and 23.

When the medium feeding gate 20 is rotated to a position close to the horizontal position, the slope 25B of the locking portion 25 causes the stopper 2 to move.
8 (see FIGS. 7 and 13). When the rotation further proceeds, the U-shaped locking portion 25 is rearward (rightward in FIG. 18).
It elastically deforms, rides on the standing wall surface 28A (see FIG. 13) of the stopper 28, and moves upward while pressing the side surface of this standing wall surface 28A.

Then, when the standing wall surface 28A disappears, the locking portion 25 moves forward due to its elastic force, and the step portion 25A of the locking portion 25 causes the upper surface 28B of the stopper 28 to move.
(See FIG. 13), and the state shown in FIG. 19 is obtained. In this state, the oval shaft portions 22 and 23 are in a horizontally long horizontal state, and cannot be slipped out from the slits 51A, 52A, and 53A, and the locking portion 25 is restricted from moving downward, and the assembling is completed. To do. It should be noted that if the arm 24 is set such that some elastic deformation remains after the assembly is completed, it is possible to apply an initial pressing force in the closing direction to the gate body 21 in the state of FIG.

In the state after the assembling, the medium 60 fed from above comes into contact with the gate main body 21 and pushes the gate main body 21 to rotate it to open the conveying path. When the gate body 21 is opened, the stopper portion 25 is restricted from moving downward by the stopper 28.
The arm portion 24 elastically deforms and bends as shown in FIG. As a result of this elastic deformation, the gate body 21 receives an elastic force from the arm portion 24 in the direction of closing the transport path. Therefore, when the medium 60 passes through the gate main body 21 portion, the gate main body 21 is returned to the position where the transport path in FIG. 19 is closed by the elastic force of the arm portion 24.

In order to facilitate the mounting of the medium feeding gate 20 on the guide cover 50, the locking portion 25 is formed in a U shape, and the step portion 25A is provided at the outer position of the tip. Alternatively, the stepped portion 25A may not be provided.

Furthermore, it is also possible to configure the embodiment as follows. A straight extension of the arm portion 24 is used as the locking portion 25. In this case, if the medium feeding gate 20 is rotated and attached as in the above-described embodiment, when the locking portion 25 rides on the standing wall surface 28A, the arm portion 24 elastically deforms in an arc shape and the standing wall surface 28A. The arm 24 will return to its original shape when the value exceeds.

The slope 25B of the locking portion 25 and the step portion 25
The one corresponding to A is provided on the stopper 28 side. That is,
As shown in FIG. 21, a locking claw portion including a slope 28C and a step portion 28D is provided on the vertical wall surface 28A of the stopper 28. Note that, in FIG. 21, the locking portion 25 of the medium feeding gate 20 is not formed in a U shape.

As the arm portion 24, for example, one which is curved in an upward convex arc shape is used. Slopes 25B and 28 provided on the locking portion 25 and the stopper 28
Instead of the locking claw formed of C and the step portions 25A and 28D, a locking claw having a spherical projection at its tip is used.

The locking claws formed by the slopes 25B and 28C and the step portions 25A and 28D provided on the locking portion 25 and the stopper 28 are provided on both sides (see FIG. 1) instead of the front end of the locking portion 25.
