Abstract

PURPOSE:To integrally compose a medium clamping mechanism and an end aligning mechanism, and to reduce it by combining a shutter, a square roller and a ball. CONSTITUTION:When the end of a medium is introduced into its gap 15, a square roller 13 is rotated in a direction of an arrow C. When the rotation is started, the periphery of the square roller immediately presses a ball to hold the medium therebetween to convey the medium in a direction of an arrow A. When the end of the medium is brought into contact with a shutter 12, the medium is not conveyed any further in the direction of the arrow A, but stopped, and the ends of the media are aligned at predetermined position. The square roller is rotated at a predetermined angle, and stopped at a position where the peripheral flat part 13a is opposed to the ball 14. In this case, the peripheral corner 13b of the roller is opposed to the ball 14, and the medium is grasped therebetween. Accordingly, even if the operator releases the medium in this state, the medium is not dropped.

A media clamping and leading edge aligning mechanism is characterized in that the peripheral corners are arranged so as to exert a force to clamp the media between them when they face the ball.

[Industrial application field]

The present invention relates to a clamping and leading edge alignment mechanism for recording media (hereinafter referred to as media) such as passbooks and slips used in banks, for example.

In recent years, terminal devices for online systems used in banks, etc. are required to be smaller, easier to replace, and more accurate in processing, and media clamping and edge alignment mechanisms are also required to be smaller. Ru.

[Conventional technology]

A conventional device for clamping a medium and aligning the leading edge of the medium has a separate part for clamping the medium and a part for aligning the leading edge of the medium. For this reason, if it was necessary to downsize the device, only one of the mechanisms could be provided.

Such a conventional medium clamping mechanism will be explained with reference to FIGS. 3 and 4. The medium 1 is a recording medium such as a slip, and is inserted into a medium insertion slot of a bank terminal device in the direction of arrow A. When the leading end of the medium 1 reaches the position of the sensor 2, the solenoid 3 is energized and operates in the direction of arrow B, rotating the shaft 5 against the force of the spring 4. A plurality of clamp members 6 are fixed to this shaft 5, and as the shaft 50 rotates, the clamp members 6 descend and grip the leading end of the medium 1 between these clamp members 6 and the support base 7 of the medium insertion port. do. Thereby, even if the operator releases the medium 1, the medium 1 will no longer fall. When preparation for the next printing is completed in a printer section (not shown) inside the apparatus, the pinch roller 9 moves to the transport roller 8 side and grips the medium 1 between them. Next, solenoid 3
is excited, and the restoring force of the spring 4 rotates the shaft 5 in the opposite direction, causing the clamp member 6 to rise.

Next, the medium 1 is further conveyed in the direction A by these rollers 8.9 into the inside of the printer section, and when the required printing is completed, it is again discharged to the medium insertion port.

[Problem to be solved by the invention]

As described above, in the conventional media printing device, it has not been possible to provide both a mechanism for clamping the medium and a mechanism for aligning the leading edge of the medium in the same device while achieving miniaturization and cost reduction.

The present invention was devised under these circumstances, and provides a media clamping/leading edge aligning mechanism in which the media clamping mechanism and leading edge aligning mechanism are configured as the same mechanism, thereby making it possible to downsize the device. The purpose is to

[Means to solve the problem]

In order to solve such problems, according to the present invention, as shown in FIG.
1), a leading edge alignment shutter (12) disposed so as to be able to protrude and retract across the passage, and a corner roller (13) for conveyance disposed on the front side of the shutter in the medium insertion direction;
The ball (14) is biased towards the corner roller and is arranged to rotate freely, and when the peripheral flat part (13a) of the corner roller faces the ball, there is a medium between them. A media clamp/tip characterized in that the peripheral corner (13b) is arranged so as to exert a force to clamp the media between the peripheral corners (13b) when facing the ball. An alignment mechanism is provided.

[Operation] First, as shown in FIG. 1(a), when the medium (1) is inserted, the peripheral flat portion (13a) of the square roller (13) faces the ball (14). Therefore, a gap (15) is formed between the square roller and the ball to allow the passage of the medium. Moreover, the shutter (12) protrudes across the medium insertion path (11). In this state, the medium is inserted along the medium insertion path (11) in the direction of the arrow.

When the leading edge of the medium enters this gap (15), as shown in Fig. 1(b)
As shown, the square roller (13) rotates in the direction of arrow C. Immediately after the rotation starts, the peripheral portions of the square rollers begin to press the balls, and the medium is conveyed in the direction of the arrow with the medium sandwiched between them.

- When the leading edge of the medium comes into contact with the shutter (12), the medium is no longer conveyed in the direction of the arrow and stops, and the leading edge of the medium is aligned at a predetermined position.

The square roller rotates by a predetermined angle and stops at a position where the peripheral plane portion 13a and the ball 14 face each other. At this time, the peripheral corner part (13b) of the corner roller faces the ball (14),
Grip the medium between them.

Therefore, in this state, even if the operator releases the medium, the medium will no longer fall. When preparation for the next printing is completed in, for example, a printer section (not shown) inside the apparatus, the shutter 12 is retracted from the medium insertion path 15 as shown in FIG. The material is further conveyed in the direction indicated by the arrow.

〔Example〕

FIG. 2 is a perspective view showing an embodiment of the recording medium clamp/edge aligning mechanism of the present invention. In the drawings, members that are the same as those shown in FIG. 1 are designated by the same reference numerals.

This embodiment is a media clamp/edge alignment mechanism in a passbook/slip printer used as a terminal device for an online system such as a bank, and the medium is a slip.
It goes without saying that the present invention can also be applied to other devices or media.

The support base 7 forms an insertion part for the medium 1, and the medium 1 is attached to the support base 7.
The medium is inserted in the direction of arrow A along the medium passage 11 (medium insertion port) along the top surface of the medium. A plurality of shutters 12 arranged in a line in a direction perpendicular to the insertion direction A of the medium 1 are connected to means (not shown) on the lower side of the support base 7.
It can protrude further upwards or retreat to the lower side of the support stand 7.

A steel ball 14 rotatably supported by a holder 21 is biased upward by a spring 22 on the near side of the shutter 12 in the medium insertion direction A, and a part of the ball 21 touches the upper surface of the support base 7. It stands out. A square roller 13 for conveyance is disposed opposite to the upper side of the ball 21, and the square roller 13 is fixed to a shaft 23. This shaft 23 is provided with a ratchet 24, which allows the shaft 23 to rotate in only one direction. Ratchet 24
is connected to a rotary solenoid 27 via a link 25 and a lever 26, and when this solenoid 27 drives the lever 26 in the direction of the arrow, the ratchet 24 is rotated by 45 degrees via the link 26. At this time, the shaft 23, that is, the square roller 13 rotates 45 degrees in the direction of arrow C.

On the other hand, when the solenoid 27 drives the lever 26 in the direction opposite to the arrow, the ratchet 24 moves 4 in the opposite direction.
Although it rotates by 5 degrees, it just idles on the shaft 23 and the square roller 13 does not rotate.

The periphery of the square roller 13 is made of rubber or the like, and it is desirable that the corner portions 13b (FIG. 1) be somewhat rounded. As described above, when the peripheral flat part 13a of the square roller 13 faces the ball 14, a gap is formed between them that allows the passage of the medium 1, and when the corner part 13b faces the ball 14, a gap is formed between them to allow the passage of the medium 1. exerts a force that clamps the medium between them. Although the square roller 13 and the ball 14 are not shown as a pair, in reality there are multiple pairs in the medium insertion direction A.
are arranged in a direction perpendicular to.

The operation of this embodiment is as described above. That is, initially, the corner roller 13 is in a position where the peripheral flat portion 13a faces the ball 14, and the shutter 12 protrudes upward. Therefore, when the operator inserts the medium 1 in the direction of arrow A, there is a gap between the square roller 13 and the ball 14 that allows the medium to pass through. When the medium sensor 2 detects the leading edge of the medium 1, the solenoid 27 is driven in the direction of the arrow.
The square roller 13 rotates 45° in the direction of arrow C. Immediately after the rotation starts, the surrounding portions of the square rollers begin to press against the balls, and the medium is conveyed in the direction of the arrow with the medium 1 sandwiched between these rollers. When the leading edge of the medium comes into contact with the shutter (12), the medium is no longer conveyed in the direction of arrow A (it stops) and the leading edge of the medium is aligned at a predetermined position.When the square roller 13 rotates 45 degrees, , the solenoid 27 stops and returns in the opposite direction of the arrow.At this time, the peripheral corner 113b of the corner roller faces the ball 14,
The medium 1 is held between these. When preparation for printing is completed in a printer section (not shown) inside the apparatus, the shutter 12 retreats downward, and the lower pinch roller 9 rises to grip the medium 1 between it and the conveyance roller 8. The solenoid 27 is driven again in the direction of the arrow C, and the square roller 13 is rotated by 45 degrees in the direction of the arrow C. As a result, the corner roller 13
A gap is again formed between the ball 14 and the ball 14 to allow the medium 1 to pass therethrough.

Next, the medium 1 is further conveyed in the six directions of arrows while being sandwiched between a conveyance roller 8 and a pinch roller 9, and required printing is performed in a printer section inside the apparatus. After the required printing is completed, the medium 1 is ejected to an operator (not shown). In addition,
In the embodiment shown in FIG. 2, a plurality of transport rollers 8 mounted on a shaft 28 and a corresponding pinch roller 9 are shown on the other side of the shutter 12 with respect to the transport direction of the medium 1. , it is actually placed slightly closer to the front.

〔Effect of the invention〕

As explained above, according to the present invention, the shutter 12
By combining with the square roller 13 and the ball 15,
The mechanism for clamping the medium and the mechanism for aligning the leading ends can now be configured as one unit. This results in
In particular, the dimensions of these mechanisms in the transport direction A of the medium 1 can be shortened, making it possible to downsize the apparatus.
