The housing 101 is provided with a storage portion (not shown) for accommodating the discharge base 110, and the storage portion is provided with a rail portion (not shown) that engages with the first guide portion 111b. As the first guide portion 111b moves along the rail portion, the first tray 111 slides with respect to the storage portion. Further, on the first mounting surface 111a, a first recess 111c for accommodating the second tray 112 is formed in the central portion of the direction A2 orthogonal to the medium discharge direction. The first recess 111c is provided with first rail portions 111d extending in the medium discharge direction A1 at both ends of the direction A2 orthogonal to the medium discharge direction.

The second tray 112 is provided with second guide portions 112b extending in the medium discharge direction A1 at both ends of the direction A2 orthogonal to the medium discharge direction. As the second guide portion 112b moves along the first rail portion 111d, the second tray 112 slides with respect to the first recess 111c of the first tray 111.

The stopper unit 120 is provided on the second tray 112 and has a stopper 121, a support member 122, and a restraining member 123. The stopper unit 120 may be foldably provided on the second tray 112 so that it can be stored in the housing 101 together with the discharge base 110.

4A, 4B and 4C are schematic views for explaining the structure of the second tray 112 and the stopper unit 120.

FIG. 4A is a schematic view of the second tray 112 and the stopper unit 120 viewed from above, FIG. 4B is a schematic view of the second tray 112 and the stopper unit 120 viewed from the side, and FIG. 4C is a schematic view of the second tray 112. It is a schematic view which looked at the stopper unit 120 from the downstream side. 4A, 4B and 4C show the second tray 112 separated from the first tray 111. In FIGS. 4A, 4B and 4C, the stopper unit 120 is arranged at the downstream end of the second tray 112.

As shown in FIGS. 2, 4A, 4B and 4C, a second recess 112c is formed on the second mounting surface 112a of the second tray 112 at the center of the direction A2 orthogonal to the medium discharge direction. ing. As shown in FIGS. 4A and 4C, the second recess 112c is provided with second rail portions 112d extending in the medium discharge direction A1 at both ends of the direction A2 orthogonal to the medium discharge direction.

As shown in FIGS. 2, 4A, 4B and 4C, the stopper 121 is provided on the second tray 112. The stopper 121 is formed in a plate shape so as to be orthogonal to the medium discharge direction A1. As shown in FIGS. 4A and 4C, stopper guide portions 121a are provided at both ends of the direction A2 orthogonal to the medium discharge direction at the lower end of the stopper 121. As the stopper guide portion 121a moves along the second rail portion 112d, the stopper 121 slides in the second tray 112 within the range corresponding to the second recess 112c. As described above, the stopper 121 is provided so as to be movable in the medium discharge direction A1 on the second mounting surface 112a of the second tray 112 by the medium discharged from the medium discharge device 100. However, the stopper 121 does not move in the direction A3 orthogonal to the second mounting surface 112a.

Further, as shown in FIGS. 4A and 4B, a first spring 121b such as a tension spring or a mainspring spring is provided between the stopper 121 and the upstream end of the second recess 112c. The first spring 121b is an example of the second load member, and applies a force to the stopper 121 in the direction opposite to the medium discharge direction A1, that is, toward the upstream side. The force applied to the stopper 121 by the first spring 121b is set to be smaller than the value obtained by subtracting the sliding load of the stopper 121 from the force applied to the stopper unit 120 by the discharged medium. As a result, the medium discharge device 100 can move the stopper unit 120 in the medium discharge direction A1 by the discharged medium against the force of the first spring 121b. Further, the force applied to the stopper 121 by the first spring 121b is set to be larger than the sliding load of the stopper 121. As a result, the medium discharging device 100 can return the stopper 121 to the state before discharging the medium by the first spring 121b when the medium is not discharged. In addition, instead of the first spring 121b, another load member such as rubber may be used.

As shown in FIGS. 2, 4A and 4B, support members 122 are provided at both ends of the direction A2 orthogonal to the medium discharge direction at the upper end of the stopper 121. The support member 122 is formed in a plate shape so as to be orthogonal to each of the stopper 121 and the second mounting surface 112a. As shown in FIG. 4B, a cam-shaped opening 122a is formed in the central portion of the support member 122. In the present embodiment, the opening 122a extends in the direction A3 in which the two right-angled sides are orthogonal to the medium discharge direction A1 and the second mounting surface 112a, respectively, and the right-angled corners are arranged on the downstream side and above. It has the shape of a substantially right triangle.

The stopper 121 and the support member 122 are integrally formed. The stopper 121 and the support member 122 may be formed separately.

As shown in FIGS. 2, 4A, 4B and 4C, the restraining member 123 is provided on the second tray 112 so as to face the stopper 121. The restraining member 123 is formed in a plate shape so as to be arranged substantially parallel to the stopper 121. At the upper end of the restraining member 123, projecting portions 123a projecting outward in the direction A2 orthogonal to the medium discharge direction are provided at both ends of the direction A2 orthogonal to the medium discharge direction. Each protrusion 123a is engaged with each opening 122a so as to be in contact with the end of each opening 122a.

As will be described later, the support member 122 brings the downstream and upper end 123b of the protrusion 123a in the medium discharge direction A1 into contact with the downstream and upper end 122b of the opening 122a in the medium discharge direction A1. The restraining member 123 is supported (see FIG. 4B). In the following, the downstream and upper end 123b of the protruding portion 123a in the medium discharge direction A1 may be referred to as a contacted portion. Further, the end portion 122b on the downstream side and the upper side of the medium discharge direction A1 of the opening portion 122a that comes into contact with the contacted portion 123b may be referred to as an abutting portion.

The restraining member 123 is provided so as to be movable in the medium discharging direction A1 together with the stopper 121 by the medium discharged from the medium discharging device 100. However, since the restraining member 123 is engaged with the stopper 121 via the opening 122a having a cam shape, the restraining member 123 can also move in the direction A3 orthogonal to the second mounting surface 112a.

As shown in FIGS. 4A, 4B and 4C, the groove member 113 is provided in the second recess 112c. As shown in FIGS. 4A and 4C, the groove member 113 is provided with a plurality of groove portions 113a extending in the direction A2 orthogonal to the medium discharge direction, respectively. The groove portions 113a are arranged side by side at intervals in the medium discharge direction A1. As described above, a plurality of groove portions 113a are provided on the second mounting surface 112a. However, the groove 113a is not formed near the upstream end of the second recess 112c. As shown in FIG. 4B, at least one side surface of each groove 113a is formed so as to be inclined with respect to the direction A3 orthogonal to the second mounting surface 112a. In particular, in the example shown in FIG. 4B, the downstream side surface of each groove 113a is inclined so as to gradually move upward toward the downstream side. The side surface of each groove 113a on the upstream side may be formed so as to gradually incline upward toward the upstream side.

Further, as shown in FIGS. 4B and 4C, a second spring 113b is provided between the groove member 113 and the bottom of the second tray 112. The second spring 113b applies an upward force to the groove member 113 to hold the groove member 113 at a predetermined height. Further, as shown in FIGS. 4A, 4B and 4C, the groove member 113 is provided with a lever 113c protruding from the downstream end of the second tray 112. The lever 113c is an example of a release member, and pushes down the groove member 113 according to the operation of the user.

As shown in FIG. 4C, the stopper 121 is provided so as not to face the groove member 113. On the other hand, when the upper end of the protruding portion 123a is in contact with the upper end of the opening 122a, the suppressing member 123 does not contact the groove member 113, and the lower end of the protruding portion 123a is in contact with the lower end of the opening 122a. In this case, it is provided so as to be aligned with the groove portion 113a of the groove member 113. However, even when the lower end of the protruding portion 123a is in contact with the lower end of the opening 122a, the suppressing member 123 is provided so as not to come into contact with the groove member 113 when the groove member 113 is pushed down by the lever 113c. Has been done.

5A, 5B, 5C, 6A and 6B are schematic views for explaining the operation of the stopper unit 120 when ejecting the medium.

FIG. 5A shows the stopper unit 120 before discharging the medium.

As shown in FIG. 5A, before discharging the medium, the stopper 121 is arranged near the upstream end of the second recess 112c by the force applied by the first spring 121b in the direction opposite to the medium discharging direction A1. To. Further, since the second tray 112 is inclined so as to gradually move upward toward the medium discharge direction A1, a force is applied to the restraining member 123 in the direction opposite to the medium discharge direction A1 due to its own weight. Further, in the vicinity of the upstream end of the second recess 112c, the groove 113a is not formed in the groove member 113. As a result, the restraining member 123 stops at a position where the upstream and upper end 123c of the protruding portion 123a comes into contact with the upstream and upper end 122c of the opening 122a.

FIG. 5B shows a stopper unit 120 to which the tip of the first ejected medium D comes into contact.

As shown in FIG. 5B, when the tip of the medium D first discharged by the discharge roller of the medium discharge device 100 comes into contact with the suppression member 123, the suppression member 123 receives a force toward the medium discharge direction A1 by the medium D. Is added. As a result, the restraining member 123 is placed at a position where the contacted portion 123b, which is the downstream and upper end of the protruding portion 123a, comes into contact with the contacting portion 122b, which is the downstream and upper end of the opening 122a. Moving. In this state, the medium D pushes the suppressing member 123 in the medium discharge direction A1, and the supporting member 122 brings the contacted portion 123b into contact with the contacting portion 122b to support the suppressing member 123. That is, the suppressing member 123 is sandwiched and supported by the support member 122 and the medium D.

FIG. 5C shows the stopper unit 120 during medium ejection.

As shown in FIG. 5C, while the medium D is being discharged, the medium D continues to apply a force toward the medium discharge direction A1. By this force, the medium D keeps pushing the suppressing member 123 in the medium discharging direction A1, and the supporting member 122 keeps the contacted portion 123b in contact with the contacting portion 122b and continues to support the suppressing member 123. The restraining member 123 is sandwiched and supported by the supporting member 122 and the medium D, and moves in the medium discharging direction A1 without falling into the groove 113a. A force directed toward the medium discharge direction A1 is applied to the stopper 121 by the suppressing member 123 pushed by the medium D, and the stopper 121 is applied to the stopper 121 together with the suppressing member 123 in the medium discharging direction A1 against the force of the first spring 121b. Move towards.

As described above, the restraining member 123 has the contacted portion 123b, and the supporting member 122 has the contacted portion 123b while the stopper 121 is moving on the second mounting surface 112a of the second tray 112. It has a contact portion 122b that comes into contact with. While the stopper 121 is moving on the second mounting surface 112a of the second tray 112, the support member 122 brings the contacted portion 123b into contact with the abutting portion 122b and does not fit into the groove portion 113a. The restraining member 123 is supported as described above.

FIG. 6A shows the stopper unit 120 immediately after the completion of the medium discharge.

As shown in FIG. 6A, when the discharge of the medium D is completed and the medium D is stopped, the stopper 121 is stopped. In addition, the suppressing member 123 also temporarily stops. In the state shown in FIG. 6A, the restraining member 123 is stopped at a position where the contacted portion 123b comes into contact with the abutting portion 122b.

FIG. 6B shows the stopper unit 120 after a lapse of a predetermined time from the state shown in FIG. 6A.

As shown in FIG. 6B, when the medium D is stopped, no force is applied to the restraining member 123 in the medium discharging direction A1 by the medium D. Therefore, the medium D does not press the suppressing member 123 in the medium discharging direction A1. As a result, the restraining member 123 is not sandwiched and supported by the supporting member 122 and the medium D. In this way, when the stopper 121 is stopped, the support member 122 releases the support of the restraining member 123. When the support by the support member 122 is released, the restraining member 123 falls due to its own weight and fits into the groove portion 113a existing at the corresponding position.

Since the second tray 112 is inclined so as to gradually move upward toward the medium discharge direction A1, even if the restraining member 123 is stopped at a position not facing the groove 113a, the restraining member 123 is placed in the second tray. It moves along the surface 112a to a position facing the groove 113a. Further, since the downstream side surface of each groove 113a is inclined so as to gradually move upward toward the downstream side, the restraining member 123 smoothly falls along the inclined side surface.

The restraining member 123 is fixed by fitting into the groove 113a. The restraining member 123 stops at a position where the lower end 123d of the protrusion 123a comes into contact with the lower end 122d of the opening 122a. The stopper 121 is also fixed by the lower end 122d of the opening 122a coming into contact with the lower end 123d of the fixed protrusion 123a of the restraining member 123. As a result, the suppressing member 123 suppresses the movement of the stopper 121, and the stopper 121 stops at a position corresponding to the size of the medium. Therefore, thereafter, when a new medium is discharged, the stopper 121 is fixed and does not move, and the tip of the discharged medium is aligned at the position where the stopper unit 120 is stopped. Further, the stopper 121 also prevents the discharged medium from falling beyond the tip of the discharge table 110 from the discharge table 110.

7A and 7B are schematic views for explaining an operation when the stopper unit 120 is returned to the state before the medium is discharged after the medium is taken out from the discharge table 110.

FIG. 7A shows the stopper unit 120 when the lever 113c is operated by the user.

As shown in FIG. 7A, when the lever 113c is operated by the user and pushed down downward, the entire groove member 113 is pushed down in conjunction with the lever 113c against the force of the second spring 113b. As described above, in the restraining member 123, the groove member 113 is pushed down by the lever 113c even when the lower end portion 123d of the protruding portion 123a is in contact with the lower end portion 122d of the opening portion 122a. At the time, it is provided so as not to come into contact with the groove member 113. Therefore, the engagement between the restraining member 123 and the groove 113a is released. In this way, the lever 113c pushes down the groove member 113 according to the operation of the user to release the alignment between the restraining member 123 and the groove portion 113a.

FIG. 7B shows the stopper unit 120 after a lapse of a predetermined time from the state shown in FIG. 7A.

As shown in FIG. 7B, when the restraining member 123 and the groove 113a are disengaged, the stopper 121 together with the restraining member 123 is subjected to a force applied by the first spring 121b in the direction opposite to the medium discharging direction A1. It moves in the direction opposite to the discharge direction A1. In this way, when the lever 113c is operated by the user, the stopper 121 is moved in the direction opposite to the medium discharge direction A1 by the first spring 121b. After that, the stopper unit 120 moves to the vicinity of the upstream end of the second recess 112c and stops. As a result, the suppressing member 123 returns to the position of the suppressing member 123 shown in FIG. 5A.

The user can easily return the stopper unit 120 to the initial position simply by pushing down the lever 113c when the medium discharging device 100 is stored or when a medium having a different size is newly conveyed. Therefore, the medium discharging device 100 can improve the convenience of the user.

The stopper unit 120 operates even when the second tray 112 is housed in the first recess 111c of the first tray 111, in the same manner as when the second tray 112 is pulled out from the first tray 111.

Further, the discharge table 110 (first tray 111 and second tray 112) is not provided so as to be inclined with respect to the installation surface of the medium discharge device 100, but is provided horizontally with respect to the installation surface of the medium discharge device 100. You may. In that case, as shown in FIG. 6A, if the medium D stops at a position where the suppressing member 123 does not face the groove 113a, the suppressing member 123 may not fall into the groove 113a due to its own weight and may not fit into the groove 113a. .. However, even in that case, the stopper unit 120 is stopped at a position corresponding to the size of the medium, and the tip of the discharged medium is aligned at the position where the stopper unit 120 is stopped. After that, when a new medium is discharged and the restraining member 123 stops at a position facing the groove 113a, the restraining member 123 falls by its own weight and fits into the groove 113a, and the stopper 121 is fixed. In that case, the tips of the media discharged after that are aligned at the positions where the stopper unit 120 is fixed.

Similarly, the side surface of each groove 113a is not formed so as to be inclined with respect to the direction A3 orthogonal to the second mounting surface 112a, but is formed parallel to the direction A3 orthogonal to the second mounting surface 112a. You may be. Also in this case, if the medium D stops at a position where the suppressing member 123 does not face the groove 113a, the suppressing member 123 may not fit into the groove 113a. However, the tips of the discharged media are aligned at the positions where the stopper unit 120 is stopped. After that, when a new medium is discharged and the suppressing member 123 stops at a position facing the groove 113a, the suppressing member 123 fits into the groove 113a.

As described in detail above, the medium ejection device 100 moves the stopper 121 by the ejecting medium. The medium discharge device 100 is provided with a restraining member 123 that is fitted in the groove 113a to suppress the movement of the stopper 121, and supports the restraining member 123 so as not to fit into the groove 113a while the stopper 121 is moving. , The stopper 121 is moved to a position corresponding to the size of the medium. As a result, the medium ejection device 100 can move the stopper 121 to a position corresponding to the size of the medium without bothering the user, and can satisfactorily align the tips of the ejected media. It became. Therefore, the medium discharging device 100 can improve the convenience of the user and shorten the working time of the medium reading work by the user.

8A, 8B and 8C are schematic views for explaining the stopper unit 220 according to another embodiment.

In this embodiment, the stopper unit 220 is used instead of the stopper unit 120. The stopper unit 220 has a stopper 221 and a support member 222 and a restraining member 223.

An L-shaped opening 222a is formed in the central portion of the support member 222. In this embodiment, the opening 222a extends in the direction A3 in which two sides are orthogonal to the medium discharge direction A1 and the second mounting surface 112a, respectively, and the angle at which the two sides intersect is arranged on the downstream side and above. It has a shape. The support member 222 supports the suppression member 223 by locking the protruding portion 223a of the suppression member 223 to a region 222b on the downstream side and the upper side of the medium discharge direction A1 of the opening 222a. The protruding portion 223a is an example of a locked portion. Further, in the following, the region 222b on the downstream side and the upper side of the medium discharge direction A1 of the opening 222a that locks the protruding portion 223a may be referred to as a locking portion.

A third spring 223b is provided between the stopper 221 and the restraining member 223. The third spring 223b is an example of the first load member, and applies a force to the restraining member 223 so as to be separated from the stopper 221, that is, the protruding portion 223a is separated from the locking portion 222b. Instead of the third spring 223b, another load member such as rubber may be used.

As shown in FIG. 8A, the stopper unit 220 is arranged near the upstream end of the second recess 112c before discharging the medium. A force directed in the direction opposite to the medium discharge direction A1 is applied to the restraining member 223 by the third spring 223b. Further, in the vicinity of the upstream end of the second recess 112c, the groove 113a is not formed in the groove member 113. As a result, the restraining member 223 stops at a position where the protruding portion 223a comes into contact with the upstream and upper end portions 222c of the opening 222a.

As shown in FIG. 8B, while the medium D is being discharged, a force is applied to the restraining member 223 by the medium D toward the medium discharge direction A1. As a result, the restraining member 223 moves to a position where the protruding portion 223a is locked by the locking portion 222b against the force of the third spring 223b. In this state, the support member 222 holds and supports the restraining member 223 by locking the protruding portion 223a to the locking portion 222b. The restraining member 223 is held and supported by the supporting member 222, and moves in the medium discharge direction A1 together with the stopper 221 without falling into the groove 113a.

As shown in FIG. 8C, when the medium D is stopped, the stopper 221 and the restraining member 223 are stopped. When the medium D is stopped, no force is applied to the restraining member 223 in the medium discharging direction A1 by the medium D. Therefore, the medium D does not press the restraining member 223 in the medium discharging direction A1. As a result, the restraining member 223 is again moved by the third spring 223b to a position where the protruding portion 223a comes into contact with the upstream and upper end portions 222c of the opening 222a, and the protruding portion 223a is moved from the locking portion 222b. Separate. In this way, the support member 222 releases the holding and support of the restraining member 123 by separating the protruding portion 223a from the locking portion 222b by the third spring 223b. When the holding and support by the supporting member 222 is released, the suppressing member 223 falls by its own weight and fits into the groove portion 113a located on the upstream side of the suppressing member 223.

As described in detail above, even when the stopper unit 220 is used, the medium discharging device can satisfactorily align the tips of the discharged media without bothering the user.

Although suitable embodiments have been described above, the embodiments are not limited thereto. For example, the first tray 111 may not be provided so as to be retractable from the housing 101, but may be provided so as to be fixed to the housing 101. Similarly, the second tray 112 may not be provided so as to be retractable from the first tray 111, but may be provided so as to be fixed to the first tray 111. Further, the second tray 112 may be omitted, and the stopper unit may be provided on the first tray 111. Further, a third tray may be provided so as to be able to be further pulled out from the second tray 112, and the stopper unit may be provided on the third tray.

Further, the suppressing member and the supporting member are not limited to the above examples. For example, the supporting member may support the suppressing member by an electromagnet or the like. In that case, one of the support member and the restraining member has a magnetic member and a coil which are ferromagnets, and the other of the support member and the restraining member has a magnet member which is a permanent magnet. While the medium D is being discharged, a predetermined current flows through the coil under control by a CPU (not shown), and the support member and the restraining member are coupled by the magnetic member and the magnet member. On the other hand, when the discharge of the medium D is completed, a reverse current flows through the coil according to the control by the CPU (not shown), and the support member and the suppression member are separated. As a result, the support member supports the restraining member while the stopper is moving, and releases the support of the restraining member when the stopper stops.
