Japanese Utility Model Publication No. 5-69010

  The paper width aligning device described in Patent Document 1 not only controls the movement of the first arm and the second arm when paper width is aligned, but also the amount of rotation of the second arm relative to the first arm. Need to control. In particular, the sheet width adjusting device changes the amount of rotation of the second arm with respect to the first arm in accordance with the thickness of the sheet to be conveyed, so that the control becomes complicated.

  Accordingly, an object of the present application is to provide a recording medium width adjusting device that can easily perform width alignment of the recording medium by simply performing a simple configuration and control.

  In the recording medium width adjusting device of the present invention, a roller having a one-way clutch is provided at one end of the width adjusting member, and the other end of the width adjusting member is rotatably attached in the width direction of the conveyance path. A recording medium width adjusting device rotates a width adjusting member by a driving force from a driving source (for example, a solenoid), so that a recording medium (certificate, slip, etc.) on the conveying path is erected on one side of the conveying path. Pull it to the reference side frame and widen it. The one-way clutch limits the rotation of the roller when the width adjusting member is rotating to the reference side frame.

  Accordingly, the recording medium width adjusting device has a simple configuration and control including one width adjusting member including a roller having a one-way clutch, and a drive source that controls the rotation of the width adjusting member. Thus, the width of the recording medium can be easily adjusted.

  The recording medium width adjusting device includes a return member (for example, a coil spring or a leaf spring) having elasticity, a solenoid, and a tension member (for example, a wire) that pulls the width adjusting member when the solenoid is energized. Also good. In this case, in the recording medium width adjusting device, when the solenoid is energized, the width adjusting member is rotated to the reference side frame side by the pulling force of the tension member, and when the energization is not performed, the width adjusting member is moved by the tensile stress of the return member. It rotates to the opposite side of the reference side frame.

  Thereby, the recording medium width adjusting device can perform the width alignment of the recording medium only by controlling the energization of the solenoid. In addition, since the recording medium width adjusting device rotates the width adjusting member using the tension member when the solenoid is energized, the solenoid and the width adjusting member can be installed at positions separated from each other. For this reason, the recording medium width adjusting device can install the solenoid in another place even when there is no space near the mounting position of the width adjusting member. There is no need to provide a space for installing the solenoid.

  The recording medium width adjusting device may be configured to attach the return member so that the angle formed with the width direction of the transport path is an acute angle and a tensile stress acts in the direction of the transport path.

  Thereby, in the recording medium width adjusting device, since the return member pulls the width adjusting member in the direction of the conveyance path, the width adjusting member can press the paper and perform the width adjustment.

  The width adjusting member of the recording medium width adjusting device may be configured to be displaced and rotated in a direction from one end where the width adjusting member is attached to the other end where the roller is provided.

  As a result, the recording medium width adjusting device can apply a pressing force according to the thickness of the recording medium because the width adjusting member is displaced in the direction of pressing the recording medium. Even justifying can be done.

  The recording medium width adjusting device may be configured to surround the roller with a protective member (for example, urethane or rubber) having elasticity.

  As a result, the recording medium width adjusting device does not damage the recording medium because the protective member having elastic force contacts the recording medium.

  The recording medium width adjusting device of the present invention can easily perform width alignment of the recording medium with a simple configuration and control.

The width of the paper P is adjusted. Hereinafter, for simplification of description, the width-shifting direction in which the paper P is shifted to the reference position is defined as the −X direction, and the direction opposite to the width-shifting direction is defined as the X direction. The direction from the conveyance path 5 toward the base blanket 10 is defined as the Y direction, and the direction from the base blanket 10 toward the conveyance path 5 is defined as the -Y direction. The direction from the back of the paper to the front of the paper is the Z direction, and the direction from the front of the paper to the back of the paper is the -Z direction.

  First, the width adjusting member 2 will be described with reference to FIGS. 2 and 3 are external views of the width adjusting member. FIG. 2 shows an exploded view and FIG. 3 shows a completed view. As shown in FIGS. 2 and 3, the width adjusting member 2 includes an arm 21, a roller 22, and a one-way clutch 23.

  The arm 21 is made of a metal plate, and a folded portion 214 having a U-shaped cross section is formed at one end in the longitudinal direction, and a roller shaft pin 213 is provided at the other end in the longitudinal direction. The roller shaft pin 213 is provided so as to protrude to the side opposite to the folded portion 214. The folded portion 214 may be formed by welding three metal plates. The arm 21 is not limited to a metal plate, and may be made of plastic or wood. Further, the roller shaft pin 213 may be provided so as to protrude to the same side as the folded portion 214.

  The arm 21 forms a long hole 211 </ b> A and a round hole 212 </ b> A in order along the longitudinal direction from the folded portion 214. At this time, the arm 21 forms the long hole 211A so that its longitudinal direction has a long diameter. Further, the arm 21 forms a long hole 211B and a round hole 212B (not shown) in the folded portion 214 so as to overlap with the long hole 211A and the round hole 212A in plan view from the side where the roller shaft pin 213 is provided. .

  The arm 21 has a roller 22 fitted with a one-way clutch 23 so that the roller 22 rotates only clockwise when viewed from the side where the arm shaft pin 213 is provided, with the side where the folded portion 214 is formed facing upward. The shaft pin 213 is inserted. The roller 22 is surrounded by a protective member having elasticity such as urethane or rubber.

  Next, the drive source 3 will be described with reference to FIGS. 4 and 5 are external views of the drive source. FIG. 4 shows an exploded view and FIG. 5 shows a completed view. As shown in FIGS. 4 and 5, the drive source 3 includes a solenoid 31, a wire (corresponding to a tension member of the present invention) 33, and a coil spring 32.

  The solenoid 31 includes a columnar tension member 311 at the tip, and is fixed to the solenoid fixing bracket 34. The solenoid 31 lowers the tension member 311 from a predetermined position when energized, and returns the tension member 311 to a predetermined position when energization ends (when no power is applied). A wire 33 is attached to the tip of the tension member 311.

  Next, the recording medium width adjusting device 1 will be described with reference to FIGS. 6 and 7 are external views of the recording medium width adjusting device. FIG. 6 shows an exploded view and FIG. 7 shows a completed view.

  As shown in FIGS. 6 and 7, the recording medium width adjusting device 1 installs the base blanket 10 on the upper side (Y direction) of the conveyance path 5. The base blanket 10 includes a columnar arm shaft pin 101 and a bent portion 102 formed by bending the tip at a right angle. The arm shaft pin 101 protrudes in the same direction as the bent portion 102. The bent portion 102 includes a spring attachment portion 102A to which the coil spring 32 is attached. The spring mounting portion 102 </ b> A is provided closer to the transport path 5 (−Y direction) than the arm shaft pin 101.

  The width adjusting member 2 is attached to the arm shaft pin 101. At this time, the width adjusting member 2 inserts the long hole 211 </ b> A and the long hole 211 </ b> B of the width adjusting member 2 into the arm shaft pin 101. For this reason, the width adjusting member 2 can be displaced in the longitudinal direction of the width adjusting member 2 and can be rotated about the arm shaft pin 101 as a rotation axis.

  Further, the shaft 41 is attached to the width adjusting member 2 through the round hole 212A and the round hole 212B. Further, on the shaft 41, the wire 33 and the coil spring 32 connected to the solenoid 31 are attached to the round hole 212B side from the center, and the E ring 42 is attached near the center. Since the width adjusting member 2 restricts the movement of the wire 33 and the coil spring 32 on the shaft 41 by the E-ring 42, even if a force is applied to the shaft 41 from the wire 33 or the coil spring 32, the elongated hole 211 </ b> A and Almost no rotation in the direction of the short diameter of the long hole 211B.

  One end of the coil spring 32 is attached to the shaft 41 of the width adjusting member 2, and the other end is attached to the spring attachment portion 102 </ b> A of the base blanket 10. The coil spring 32 has a direction (−Y direction) from the opposite direction (X direction) to the width-shifting direction so that the angle (Θ shown in FIG. 1) formed with the width direction of the conveyance path 5 becomes an acute angle. ) And attached in a stretched state.

  Since the coil spring 32 generates a tensile stress, the coil spring 32 pulls the shaft 41 of the width adjusting member 2 in the direction opposite to the width adjusting direction (X direction) and in the direction of the transport path 5 (−Y direction). That is, the coil spring 32 rotates the width adjusting member 2 in the direction opposite to the width adjusting direction (X direction) and presses the paper P on the conveyance path 5 by the width adjusting member 2.

  Further, when energized, the solenoid 31 lowers the tension member 311 from a predetermined position and pulls the wire 33, so that the shaft 41 is pulled in the width-shifting direction (−X direction). When the solenoid 31 is de-energized (when de-energized), the tension member 311 is returned to a predetermined position to stop pulling the wire 33, so that the shaft 41 is moved in the direction opposite to the width-shifting direction by the tensile stress of the coil spring 32 ( -X direction). In this way, the recording medium width adjusting device 1 can control the width adjusting member 2 to be rotatable about the arm shaft pin 101 as a rotation axis by controlling the energization to the solenoid 31.

  Next, the operation of the recording medium width adjusting device 1 will be described with reference to FIGS. 8 to 12 are diagrams illustrating the operation of the recording medium width adjusting device. FIG. 8 shows the standby position of the conveying member (before the paper is justified), and FIG. 9 shows the progress in the middle of the justification. FIG. 10 shows the width adjustment position of the conveying member, and FIG. 11 shows the progress in the middle of returning to the standby position. FIG. 12 shows the standby position of the conveying member (after completion of paper width alignment).

  As shown in FIG. 8, the transport path 5 is provided with transport guides on its top and bottom. The conveyance path 5 is provided with a conveyance guide so that the length in the width direction is longer than the length in the width direction of the paper P. The conveyance path 5 has a reference side frame 51 standing on the side wall and an opening 52 provided in the upper conveyance guide. The reference side frame 51 is used as a reference position when the paper P is aligned. Since the opening 52 is a portion where the width is adjusted, the opening 52 is provided on the transport path 5 before printing on the paper P.

  The storage medium width adjusting device 1 cuts off the energization to the solenoid 31 during standby when the width of the paper P is not adjusted. At this time, only the tensile stress of the coil spring 32 acts on the storage medium width adjusting device 1. In the storage medium width adjusting device 1, the coil spring 32 pulls the shaft 41 of the width adjusting member 2 in the direction opposite to the width adjusting direction (X direction), so that the width adjusting member 2 is rotated in the direction opposite to the width adjusting direction (X direction). Move it to the standby position.

  In the recording medium width adjusting device 1, the coil spring 32 pulls the shaft 41 of the width adjusting member 2 in the direction of the conveying path 5 (−Y direction). Since it is inclined, it is hardly displaced in the direction of the transport path 5 (−Y direction).

  The recording medium width adjusting device 1 energizes the solenoid 31 when the paper P is width aligned. At this time, as shown in FIG. 9, in the recording medium width adjusting device 1, the force that the solenoid 31 pulls through the wire 33 is larger than the tensile stress of the coil spring 32. In the recording medium width adjusting device 1, since the wire 33 pulls the shaft 41 of the width adjusting member 2 in the width adjusting direction (−X direction), the width adjusting member 2 rotates in the width adjusting direction (−X direction). The rotation of the roller 22 of the width adjusting member 2 is restricted by the one-way clutch 23.

  Further, in the recording medium width adjusting device 1, since the coil spring 32 pulls the shaft 41 in the direction of the transport path 5 (−Y direction), the width adjusting member 2 is displaced in the direction of the transport path 5 (−Y direction), The roller 22 presses the paper P on the transport path 5. At this time, the recording medium width adjusting device 1 is displaced from the state in which the width adjusting member 2 is inclined with respect to the surface of the conveyance path 5 to the inclined state through the upright state. In the recording medium width adjusting device 1, the displacement amount of the width adjusting member 2 is maximized in an upright state, and is determined according to the thickness of the paper P.

  As a result, the recording medium width adjusting device 1 pulls the paper P in the width adjusting direction (−X direction) while pressing the paper P with the roller 22 to adjust the width. As shown in FIG. 10, the recording medium width adjusting device 1 performs the width alignment of the paper P until the leading edge of the paper P comes into contact with the reference side frame 51.

  When the leading edge of the paper P comes into contact with the reference side frame 51, the recording medium width adjusting device 1 interrupts the energization of the solenoid 31. As shown in FIG. 11, in the recording medium width adjusting device 1, only the tensile stress of the coil spring 32 works. In the storage medium width adjusting device 1, the coil spring 32 pulls the shaft 41 of the width adjusting member 2 in the direction opposite to the width adjusting direction (X direction), so that the width adjusting member 2 is rotated in the direction opposite to the width adjusting direction (X direction). The width adjusting member 2 is moved to the standby position. The roller 22 of the width adjusting member 2 is rotated clockwise by the one-way clutch 23 toward the paper surface.

  Further, in the storage medium width adjusting device 1, since the coil spring 32 pulls the shaft 41 in the direction of the transport path 5 (−Y direction), the width adjusting member 2 is displaced in the direction of the transport path 5 (−Y direction), The roller 22 presses the paper P on the transport path 5. At this time, the recording medium width adjusting device 1 is displaced from the state in which the width adjusting member 2 is inclined with respect to the surface of the conveyance path 5 to the inclined state through the upright state. In the recording medium width adjusting device 1, the displacement amount of the width adjusting member 2 is maximized in an upright state, and is determined according to the thickness of the paper P.

  As a result, since the roller 22 rotates on the paper P, the recording medium width adjusting device 1 hardly pulls the paper P in the opposite direction (X direction) of the width adjusting direction. As shown in FIG. 12, the recording medium width adjusting device 1 returns the width adjusting member 2 to the standby position.

  As described above, the recording medium width adjusting device 1 can perform the width alignment of the paper P only by controlling the energization of the solenoid 31. In other words, the recording medium width adjusting device 1 can easily perform the width alignment of the paper P only by performing a simple configuration and control.

  Further, the recording medium width adjusting device 1 has the width adjusting member 2 rotatably attached thereto, and the coil spring 32 pulls the width adjusting member 2 in the direction of the transport path 5 (−Y direction). For this reason, the recording medium width adjusting device 1 can perform the width alignment while the width adjusting member 2 presses the paper P.

  Further, the recording medium width adjusting device 1 is mounted so that the width adjusting member 2 can be displaced by a long hole 211A and a long hole 211B provided in the width adjusting member 2. For this reason, the width adjusting member 2 is displaced according to the thickness of the paper P and presses the paper P. In other words, the recording medium width adjusting device 1 can perform the width alignment for any thickness of the paper P.

  Further, in the recording medium width adjusting device 1, since the roller 22 that contacts the paper P is surrounded by a protective member having elasticity, the paper P is not damaged when the paper P is pressed.

  Further, when the recording medium width adjusting device 1 is provided in a certificate issuing device, a slip issuing device, or the like, the recording medium width adjusting device 1 has a width adjusting member 2 and a coil spring on the transport path 5 in front of printing on the paper P. 32 is arranged. The recording medium width adjusting device 1 installs a solenoid 31 in an empty space such as a certificate issuing device or a slip issuing device. The recording medium width adjusting device 1 attaches the wire 33 from the solenoid 31 to the shaft 41 of the width adjusting member 2.

  As described above, in the recording medium width adjusting device 1, the solenoid 31 can be installed at a remote location even if there is no space near the position where the width adjusting member 2 is attached. It is not necessary to provide a space for installing the solenoid 31 in the vicinity of. As a result, the recording medium width adjusting device 1 can be applied to an existing certificate issuing device, slip issuing device or the like without changing a new space in the vicinity of the mounting position of the width adjusting member 2. .
