The press lever 4 is rotatably supported around a fulcrum 5, and is connected to a solenoid 8 via links 6 and 7. When the solenoid 8 is on, the lever is down, and when it is off, the lever is up. 10 is a pair of take-in rollers, 11 is a traveling guide lower, 12 is a traveling guide upper,
13 is a full detection sensor, and 14 is a medium.

9A and 9B are schematic explanatory views showing the operation step SA2 of the conventional example, and FIG. 9B is a side view.
(A) is a cross-sectional view taken along the line P-P of (B), showing the time of collecting the taken-in media. FIG. 10 (A),
(B) is a schematic explanatory view showing an operation step SA3 of the conventional example, (B) is a side view, (A) is a sectional view taken along the line PP of (B), showing a standby state.

The operation of the conventional example having the above-mentioned configuration will be described below with reference to FIGS. First, before starting the capturing operation, it is confirmed that the full detection sensor 13 is off. That is, if it is on, the import box 1
Is not full, the capture operation is not performed. Next, the take-up roller pair 10 is rotated by a motor (not shown) to convey the medium 14 to the state shown in FIG. 8 (SA1). When the solenoid 8 is turned on and the press lever 4 is brought into the down state from this state, the medium 14 comes under the side guide lowers R2a and L2b in the state shown in FIG. 9 (SA2). Next, after confirming that the full detection sensor 13 is off, the solenoid 8 and the motor (not shown) are turned off. With the above operation, the standby state shown in FIG. 10 is returned (SA3).

[0006]

However, according to the prior art with the above structure, the integrated medium is in a free state in the take-in box or the like, so that it is aged with changes in environmental conditions such as temperature and humidity. Although the curl occurs and the amount of the taken-in is small, the curl medium blocks the taken-in traveling path, and the sensor detects the full state. Alternatively, if it cannot be detected, there is a problem that a jam occurs at the time of importing.

In view of the above problems, the present invention obtains a structure for correcting the curl of a medium which has already been accumulated at the time of stand-by or at the time of capturing, and detects a false full detection due to the curl of the accumulated medium or a medium at the time of capturing. An object of the present invention is to provide a sheet-shaped medium stacking device that eliminates the occurrence of jams and performs a stable stacking operation.

[0008]

In order to achieve the above-mentioned object, the present invention is designed so that the integrated medium is pressed from the upper portion during standby or during loading. That is, the present invention is directed to a medium carrying means for carrying a medium into an apparatus, and a predetermined amount of overlap with the left and right ends of the medium with respect to the traveling direction of the medium located below the medium carried by the medium carrying means. And a center guide member which is positioned between the side guide members at a constant distance from the side guide members and is supported so as to be vertically movable independently, and the initial position of the center guide member is the medium conveying means. In the paper-leaf medium accumulating device, which is above the medium to be further conveyed, and which accumulates the medium conveyed between the center guide member and the side guide member at the lower side of the side guide member by intersecting the medium. The side guide member is supported so as to be movable up and down, and during standby, both the side guide member and the center guide member are in a state of pressing the medium, At the time of loading, the center guide member moves to the upper part of the medium and stands by with respect to the medium conveyed by the medium conveying means, and the medium conveyed between the center guide member and the side guide member is crossed with each other. Is integrated under the side guide member.

At this time, it is preferable that the side guide member is rotatable around the final roller of the medium conveying means as a fulcrum.
Further, it is advisable to compress the accumulated medium after the end of taking in by applying pressure for a certain period of time by the center guide member.

[0010]

With the above construction, in the present invention, both the side guide member and the center guide member are in a state of being pressed against the accumulated medium from the upper portion during standby, and the accumulated medium is always kept in a flat state. Not affected by curl. In particular, the center guide member presses the taken-in medium for a certain period of time and thereafter remains in the pressed position until the next taking-in occurs, so that some curl is corrected.

Further, even at the time of taking-in, since the side guide is in the state of pressing the medium at the time when the medium is conveyed between the side guide member and the center guide, there is no fear that the curled medium will come out of the taking-in traveling path. At this time,
If the side guide member is rotatable around the final roller of the medium conveying means as a fulcrum, the moving mechanism of the side guide member can be simplified.

Further, by compressing the collected medium after the completion of loading by the center guide member for a certain period of time, the bulk of the accumulated medium can be corrected, and more medium can be accumulated with respect to the accumulation height.

The position of 20 is gradually lowered and the shutter provided on the side guide 20 blocks the optical axis of the sensor to enter the detection state (ON state).

Reference numeral 14 is a medium, 21 is a center guide, and 22 is a micro switch. The micro switch 22 is turned on when the center guide 21 is in the reset state (up state). Reference numeral 23 is a DC motor, and the center guide 21 is supported so as to be vertically movable while maintaining a parallel state.
The reset state, which is controlled by the forward / reverse rotation of the C motor 23 (the center guide 21 descends in the forward rotation and the center guide 21 rises in the reverse rotation), is detected by the micro switch 22, and the medium pressing state is detected by the DC motor. Detects overcurrent and stops the motor.

FIGS. 5A and 5B are schematic explanatory diagrams showing operation step SB5 of the present embodiment, and FIG.
Is a side view, and (A) is a cross-sectional view taken along the line P-P of (B), showing the time of integration.

The operation of this embodiment having the above configuration will be described below with reference to FIGS. First, in the normal standby state shown in FIG.
1, the full detection sensor 13 is held in the side guide 20 and is not turned on due to the deformation of the medium over time (SB1). When the medium is taken in from this state, first the DC motor 23 is rotated in reverse and the micro switch 2
2 ON is detected, the DC motor 23 is stopped, and FIG.
As shown in, the center guide 21 is reset (SB2). In this state, it is confirmed that the full detection sensor 13 is off. (In the ON state, the take-in box 1 is full and the take-in operation is not performed.) Next, the take-up roller pair 10 is rotated by a motor (not shown) to move the medium 14 to the center guide 21 and the side guide 20.
Transport between. This state is shown in FIG. 3 (SB
3).

Thereafter, as shown in FIG. 4, when the solenoid 8 is turned on (SB4) and the DC motor 23 is rotated in the normal direction, as shown in FIG.
Since the side guide 20 and the side guide 20 pass each other, the medium is separated from the side guide 20 and accumulated in the lower part of the side guide 20 (S
B5). At this time, the order in which the solenoid 8 is turned on and the DC motor 23 is normally rotated does not significantly affect the performance. The center guide 21 descends until it abuts on the accumulated medium, presses the medium, and when it cannot descend further, an overcurrent flows to the DC motor 23, and as shown in FIGS. After t, the DC motor 23 is stopped. In this embodiment, the medium accumulated by the center guide 21 is compressed for a certain period of time during the certain period of time t. As a result, the bulk of the stacking medium can be corrected, and more media can be stacked with respect to the stacking height.

Finally, when the solenoid 8 is off, it is confirmed that the full detection sensor 13 is off, and the state returns to the state shown in FIG.

[0021]

As described in detail above, according to the present invention, a medium carrying means for carrying a medium into an apparatus, and a medium located below the medium carried by the medium carrying means are arranged in the traveling direction of the medium. On the other hand, a side guide member that overlaps the left and right ends of the medium by a predetermined amount, and a center guide member that is positioned between the side guide members at a constant interval and that is independently movably supported are provided. The initial position of the center guide member is set above the medium conveyed by the medium conveying means, and the medium conveyed between the center guide member and the side guide member is crossed with each other to move the medium below the side guide member. In a sheet-shaped medium accumulating device that accumulates on a sheet, the side guide member is supported so as to be movable up and down, and in the standby state, the side guide member and the center guide portion. Both in a state pressed against the medium,
At the time of taking-in, the center guide member moves to the upper part of the medium with respect to the medium conveyed by the medium conveying means and stands by, and the medium conveyed between the center guide member and the side guide member is crossed with the medium to convey the medium. Since they are accumulated under the side guide member, it is possible to hold the accumulation medium from above while waiting or taking in.

As a result, it becomes possible to correct the curl of the already accumulated medium at the time of standby or at the time of taking in, eliminating false full detection due to curling of the accumulated medium and occurrence of medium jam at the time of taking in. There is an effect of providing a sheet-shaped medium stacking device that performs a stable stacking operation. Further, at this time, if the side guide member can be rotated around the final roller of the medium conveying means as a fulcrum, the moving mechanism of the side guide member can be simplified and an inexpensive device configuration can be realized.

Further, by compressing the collected medium after the completion of loading by applying a pressure for a certain period of time by the center guide member, the bulk of the accumulated medium can be corrected and more media can be accumulated with respect to the accumulation height. Has the effect of increasing the ability to accumulate.
