Description

  The present invention relates to a sheet storage device used in a medium processing apparatus such as a check processing apparatus. More specifically, the present invention relates to a sheet medium storage device in which a sheet medium is fed into a storage pocket by a feed roller.

  As a medium processing apparatus for processing a sheet-like medium, a check processing apparatus for processing checks is known. The check processing device temporarily stores a supply unit for inserting checks, a conveyance path in which an image scanner and a magnetic head are arranged, and checks that are discharged from the conveyance path after images and magnetic ink characters are read by these. A check storage unit is provided. Such a check processing apparatus is disclosed in Patent Document 1, for example.

  The check storage unit includes a storage pocket formed of a rectangular vertical groove extending in the front-rear direction, a feed roller for feeding checks into the storage pocket, and a pressing roller for pressing the sent checks against the feed roller. Checks fed into the storage pocket by the feed roller are brought close to one side surface of the storage pocket and stored while being stacked in the storage pocket width direction from the side surface.

The feeding roller is disposed at a position adjacent to the front end plate that defines the front end face of the storage pocket so that almost half of the feed roller projects into the storage pocket from the front end face. The sheet-like medium fed into the storage pocket is fed rearward from the front end surface of the storage pocket by the outer peripheral surface portion of the feed roller that has entered the storage pocket, is brought to one side of the storage pocket, and has already been stored. It will be in the state piled up on the sheet-like medium.
JP 2004-206362 A

  Here, a gap is formed between a portion of the feeding roller opposite to the sheet medium feeding side and the front end plate of the storage pocket. This gap is to prevent the rotating feed roller from contacting the front end plate of the storage pocket. The outer peripheral surface of the feed roller rotates in the direction from the inside of the storage pocket to the outside of the storage pocket through the gap. Therefore, when the edge of the sheet-like medium already stored in the storage pocket hits the outer peripheral surface portion of the feeding roller, the feeding roller feeds the gap toward the gap, and may be caught in the gap and fall into a paper jam state. .

  An object of the present invention is to propose a sheet storage device in which a sheet-like medium stored in a storage pocket is prevented from being caught in a gap between a front end plate of the storage pocket and a feed roller.

In order to solve the above-described problem, the sheet-like medium storage device of the present invention includes:
A storage pocket for storing the sheet-like medium;
A feeding roller for feeding a sheet-like medium into the storage pocket;
The feed roller includes a roller main body and a small diameter portion that is formed coaxially with the roller main body and has a smaller diameter than the roller main body, and at least a part of the outer peripheral surface portion of the roller main body is formed from the front end surface of the storage pocket. Is attached to a position adjacent to the front end plate defining the front end surface so as to protrude inside the storage pocket,
The front end plate at least partially seals a gap between the front end plate and the feeding roller, and includes a protrusion for preventing entrainment extending between the outer peripheral surface of the roller body and the outer peripheral surface of the small diameter portion. It is characterized by being.

  According to the present invention, since the protrusion for preventing entrainment partially blocks the gap between the feeding roller and the front end plate, even if the feeding roller tries to draw the sheet-like medium into the gap, the drawing-in is prevented. A gap is formed between the feeding roller and the front end plate so as not to contact. In addition, since the winding prevention protrusion extends between the outer peripheral surface of the roller main body and the outer peripheral surface of the small-diameter portion, the tip of the winding prevention protrusion is located radially inside the outer peripheral surface of the roller main body. . Therefore, the sheet-like medium that is about to be drawn into the gap by sliding contact with the outer peripheral surface of the roller body does not slip through the gap between the entanglement preventing protrusion and the outer peripheral surface of the roller body and is drawn into the gap.

In the present invention, in order to seal the gap between the front end plate and the feeding roller with a constant width, the small diameter portion has a predetermined width dimension in the axial direction,
The protrusion for preventing entrainment extends from the front end plate in a direction perpendicular to the axis of the feeding roller, and the width in the axial direction is a width corresponding to a predetermined width of the small diameter portion. desirable.

Further, in order to reliably prevent the sheet-like medium from being drawn into the gap, the feeding roller includes a plurality of the small diameter portions at positions separated in the axial direction,
The front end plate may be provided with the number of protrusions for preventing entrainment corresponding to the small diameter portion.

In the present invention, feeding protrusions that protrude radially from the outer peripheral surface of the roller body are formed at both ends of the roller body.
The small-diameter portion is preferably formed between both end portions.

  In this way, the rear end of the sheet-like medium fed into the storage pocket by the feed roller is moved sideways in the storage pocket from the feed position by the feed projection. As a result, it is possible to secure an entry path for the sheet-like medium to be fed next into the storage pocket, so that the sheet-like medium to be fed next collides with the rear end portion of the sheet-like medium that has been fed first, and the paper There is no clogging.

  On the other hand, when such a feeding protrusion is formed on the feeding roller, the feeding protrusion of the feeding roller is easily engaged with the rear end portion of the already stored sheet-like medium, and the sheet-like medium is separated by a gap. There is a high possibility of getting involved. However, since the guide surface for preventing winding is formed in the present invention, the sheet-like medium is reliably prevented from being caught even when the feeding protrusion is formed.

Here, when protrusions are formed on both end portions of the roller body, the roller body has a pressing roller for pressing the sheet-like medium against the roller body.
The pressing roller preferably presses the sheet-like medium between both end portions of the roller body. If it does in this way, a sheet-like medium will be sent in a storage pocket in the state where it was bent by pinching with a feed roller and a press roller. As a result, since the so-called “waist” is formed in the sheet-like medium in the fed state, the sheet-like medium does not bend during the feeding. Therefore, it is possible to avoid the sheet-like medium that is next fed into the storage pocket from colliding with the bent sheet medium and falling into a jammed state.

  In this case, it is desirable that the small-diameter portion is formed in the vicinity of one end portion in order to avoid the pull-in due to the protrusion.

  In the present invention, the entanglement preventing protrusion for preventing the sheet-like medium from being caught in the gap formed between the front end plate of the storage pocket and the feeding roller is formed. Therefore, it is possible to avoid that the sheet-like medium already stored in the storage pocket is caught in the gap between the feeding roller and the front end plate and is torn or wrinkled. In addition, since the sheet-like medium drawn into the gap does not stagnate on the front end side of the storage pocket and does not block the entrance path of the sheet-like medium that is next fed into the storage pocket, It is also possible to avoid a paper jam at the front end side of the storage pocket.

  In the following, an embodiment of a check processing apparatus employing a sheet-like medium storage device of the present invention will be described with reference to the drawings.

(overall structure)
FIGS. 1A and 1B are a perspective view and a plan view showing a check processing apparatus according to the present embodiment. The check processing device 1 includes a main body case 2 on the apparatus main body side, and open / close covers 4 and 5 that can be opened and closed left and right around a vertical shaft 3 attached to the tip of the main body case 2.

The magnetic ink character string 6A is read. The check 6 from which these pieces of information have been normally read is subjected to printing such as “electronic payment completed”, then distributed to the first storage pocket 13 and stored in this storage pocket. The check 6 in which reading is impossible, reading abnormality, etc. is distributed to the second storage pocket 14 and stored in this storage pocket without such printing.

(Check storage)
FIG. 2 is a perspective view showing a check storage portion of the check processing device, and FIG. 3 is a cross-sectional view of the first storage pocket cut along the front end surface. As shown in FIG. 2, the check storage unit 10 includes a first branch passage 11 and a second branch passage 12, and first and second storage pockets 13 and 14 connected to the downstream ends thereof. Since the first and second storage pockets 13 and 14 have the same configuration, the first storage pocket 13 will be described, and the same reference numerals will be given to the corresponding configurations, and the second storage pocket 14 will be described. Description is omitted.

  The first storage pocket 13 is formed of a longitudinal groove having a predetermined depth that is a long rectangle in the front-rear direction, and includes left and right first and second side plates 31, 32, a front end plate 33, and a bottom plate 35 extending in parallel. An inclined guide surface 36 is formed at the front end side portion of the second side plate 32 and widens in a direction away from the first side plate 31 toward the front end plate 33. The upstream side of the inclined guide surface 36 is continuous with one inner wall surface 37 of the first branch passage 11. Next to the front end plate 33 on the inclined guide surface 36 side, a feed roller 40 for feeding the check 6 into the first storage pocket 13 is arranged. A gap B shown in FIGS. 3 to 5 is formed between the feeding roller 40 and the front end plate 33. A pressing roller 45 for pressing the check 6 against the feeding roller 40 protrudes from one inner wall surface 37 of the first branch passage 11 facing the feeding roller 40. Inside the first storage pocket 13, two vertical pressing plates 51, 52 inclined rearward at a predetermined angle from the second side plate 32 toward the first side plate 31 are arranged.

  As shown in FIG. 3, the feeding roller 40 includes a roller main body 41 and a small-diameter portion 42 that is formed coaxially with the roller main body 41 and has a smaller diameter than the roller main body 41. Both end portions 41a and 41b of the roller body 41 are provided with four feeding projections 43 that project radially from the outer peripheral surface in the radial direction, and these four feeding projections 43 are formed at equal intervals in the circumferential direction. Has been. The small-diameter portion 42 is formed between the both end portions 41a and 41b and in the vicinity of the upper end portion 41a.

  The pressing roller 45 includes a rotating shaft 46 and two pressing roller main bodies 45 a and 45 b that are coaxially attached to the rotating shaft 46 at intervals. The diameters of the pressing roller bodies 45a and 45b are the same, and the diameter is smaller than the diameter of the roller body 41 of the feeding roller 40. Further, the distance between the outer end surfaces of the pressing roller main bodies 45 a and 45 b is shorter than the roller length of the roller main body 41 of the feeding roller 40. The two pressing roller bodies 45 a and 45 b are elastically pressed between both ends 41 a and 41 b of the roller body 41.

  The pair of feed rollers composed of the feed roller 40 and the pressure roller 45 are arranged so that the nip portion A is positioned on the same plane as the surface (front end surface) 33a facing the inside of the storage pocket of the front end plate 33. Yes. For this reason, the outer peripheral surface portion 41c of the roller body 41 protrudes inside the first storage pocket 13 from the front end surface 33a.

  On the front end surface 33a of the front end plate 33, an entrainment prevention plate 53 protruding toward the feed roller 40 is attached so as to partially close the gap B between the feed roller 40 and the front end plate 33. . The entrainment prevention plate 53 has a width dimension corresponding to the width dimension of the small-diameter portion 42 of the feed roller 40 and extends parallel to the front end face 33a. Further, it extends in a direction perpendicular to the axial direction of the feed roller 40, and its tip 53 a reaches between the outer peripheral surface portion 41 c of the roller body 41 and the outer peripheral surface portion 42 a of the small diameter portion 42.

  An upper end portion of the front end plate 33 on the feed roller 40 side extends to above the feed roller 40, and a front end surface 34 a of the extended portion 34 is interposed via a convex arc surface protruding inside the first storage pocket 13. It is continuous with the other inner wall surface 38 of the first branch passage 11. At the lower end edge of the extended portion 34, an entrainment prevention rib 54 for preventing the check 6 after being fed into the first storage pocket 13 from being entrained in the gap B is formed. A surface (guide surface for preventing entrainment) 54a (see FIG. 5B) facing the inside of the storage pocket of the entrainment preventing rib 54 is the same as the front end surface 33a when viewed from the direction of the axis of the feeding roller 40. It is in a state of being stretched between the feeding rollers 40 and is formed so as to be positioned on a tangent line drawn on the outer peripheral surface portion 41 c of the feeding rollers 40.

  The check 6 fed into the first storage pocket 13 from the front end side by the feed roller 40 and the pressing roller 45 is guided by the inclined guide surface 36 so that the tip portion thereof faces the first side plate 31. Enter inside. The sent check 6 is pressed against the first side plate 31 by the vertical pressing plates 51 and 52 and stored in a stacked state in the width direction.

  Here, feeding protrusions 43 are formed at both end portions 41a and 41b of the feeding roller 40, and the pressing roller 45 presses the check 6 between the both end portions 41a and 41b. Therefore, as shown in FIG. 3, the check 6 is fed into the first storage pocket 13 while being bent by the pair of feed rollers. As a result, a so-called “waist” is formed on the check 6 in the fed state, so that the check 6 is not bent during the feeding. Further, the feeding roller 40 engages the feeding projections 43 of both end portions 41a and 41b with the rear end of the fed check 6, and moves the rear end position from the front of the nip portion A to the side. As a result, it is possible to secure an approach path for the check 6 to be sent next to the first storage pocket 13, so that the check 6 to be sent does not fall into a jamming state.

  In the check storage 10 of this example, the rear end portions of the first and second storage pockets 13 and 14 are defined by a drawer 19 that can be pulled out rearward. When the drawer portion 19 is pulled backward from the state shown in FIG. 1, the storage pockets 13 and 14 extend in the front-rear direction. Thereby, the check 6 of a long dimension can be received and accommodated.

(Function of the entrainment prevention plate)
The function of the entrainment prevention plate 53 will be described with reference to FIG. FIG. 4 is a plan view schematically showing the tip side portion of the first storage pocket. 4A shows a case where the wrapping prevention plate 53 is not attached to the front end plate 33, and FIG. 4B shows a case where the wrapping prevention plate 53 is attached to the front end plate 33.

  FIG. 4 shows a state in which the check 6 fed into the first storage pocket 13 is stagnating in the vicinity of the feed roller 40. The rear end portion 6c of the check 6 is located at a position close to the portion on the opposite side of the nip portion A across the rotation shaft 40a in the outer peripheral surface portion 41c of the roller body 41 of the feed roller 40.

  In this state, when the feed roller 40 rotates to feed the next check 6 into the first storage pocket 13, the feed protrusion 43 of the feed roller 40 and the rear end portion 6c are engaged, and this check 6 is moved to the front end. Pull back to the side. Alternatively, a portion of the roller body 41 opposite to the nip portion A on the outer peripheral surface portion 41c is in sliding contact with the rear end portion 6c, and the check 6 is pulled back to the front end side. Accordingly, when the entrainment prevention plate 53 is not attached, the rear end portion 6c of the check 6 is drawn into the gap B between the front end plate 33 and the feed roller 40 as shown in FIG. . If it becomes like this, the part drawn in the clearance gap B of the check 6 already accommodated will be torn or it will become a bag. Further, since the check 6 drawn into the gap B stagnates on the front end side of the first storage pocket 13, the check 6 that is next fed into the storage pocket is blocked, and the check 6 The front end side of the storage pocket 13 is jammed.

  On the other hand, when the entrainment prevention plate 53 is attached, it is assumed that the check 6 is pulled back to the front end side by the feeding protrusion 43 or the outer peripheral surface portion 41c of the roller body 41 as shown in FIG. However, the rear end collides with the entrainment prevention plate 53.

  As a result, since the check 6 already stored is not drawn into the gap B, it is possible to avoid the check 6 being torn or becoming a bag. Further, since the check 6 is not drawn into the gap B and does not stagnate in the storage pocket toward the front end side, an entry path for the check 6 fed into the storage pocket next is secured. Therefore, the check 6 can be prevented from jamming on the front end side of the storage pocket.

  Further, since the entrainment prevention plate 53 extends between the outer peripheral surface portion 41 c of the roller main body 41 and the outer peripheral surface portion 42 a of the small diameter portion 42, the tip 53 a is more radial than the outer peripheral surface portion 41 c of the roller main body 41. Located inside. Therefore, the sheet-like medium that is about to be drawn into the gap B by sliding contact with the outer peripheral surface portion 41 c of the roller main body 41 passes through the gap B and the outer peripheral surface portion 41 c of the roller main body 41. Will not be drawn into.

(Rib prevention rib function)
Next, the function of the entanglement preventing rib 54 will be described with reference to FIG. FIG. 5 is a plan view schematically showing the tip side portion of the first storage pocket 13, and FIG. 5 (a) is a case where the entanglement prevention rib 54 is not formed, and FIG. 5 (b) This is the case where the entanglement prevention rib 54 is formed.

  FIG. 5 shows a state in which the check 6 fed into the first storage pocket 13 is stagnating in the vicinity of the feed roller 40. The rear end portion 6c of the check 6 is located at a position close to the portion on the opposite side of the nip portion A across the rotation shaft 40a in the outer peripheral surface portion 41c of the roller body 41 of the feed roller 40.

  In this state, when the feed roller 40 rotates to feed the next check 6 into the first storage pocket 13, the feed protrusion 43 of the feed roller 40 and the rear end portion 6c are engaged, and this check 6 is moved to the front end. Pull back to the side. Alternatively, the portion of the roller body 41 opposite to the nip portion A and the rear end portion 6c are in sliding contact, and the check 6 is pulled back to the front end side. Accordingly, when the winding prevention rib 54 is not attached, the rear end portion 6c of the check 6 is drawn into the gap B between the front end plate 33 and the feeding roller 40 as shown in FIG. . If it becomes like this, the part drawn in the clearance gap B of the check 6 already accommodated will be torn or it will become a bag. Further, since the check 6 drawn into the gap B is stagnated on the front end side of the first storage pocket 13, the approach path of the check 6 fed into the storage pocket next is blocked, and the check 6 is the first. The front end side of the storage pocket 13 is jammed.

  On the other hand, when the entrainment prevention rib 54 is attached, as shown in FIG. 5B, even if the check 6 is pulled back to the front end side by the feeding protrusion 43, the rear end portion 6c is used for feeding. It collides with the entanglement prevention rib 54 immediately above the protrusion 43. Thereafter, the check 6 is guided by the guide surface 54a for preventing entanglement, and the check 6 is not caught in the gap B but is moved sideways toward the front end plate 33 in the first storage pocket 13.

  As a result, the check 6 is not drawn into the gap B and stays on the front end side of the first storage pocket 13, so that an entry path for the check 6 that is next fed into the first storage pocket 13 is secured. . Therefore, the check 6 can be prevented from jamming on the front end side of the storage pocket.

  Further, since the guide surface 54a for preventing entrainment is formed so as to be located on a tangent line drawn on the outer peripheral surface portion 41 of the feed roller 40 when viewed from the axial direction of the feed roller 40, the first storage is provided. The rear end portion 6c of the check 6 stored in the pocket is prevented from hitting the outer peripheral surface portion 41 rotating toward the gap B in the feeding roller 40, and the check 6 is reliably prevented from being caught.

  Further, even if the feeding protrusion 43 formed on the upper end portion 41a engages with the rear end portion 6c of the check 6 and tries to pull the check 6c back toward the front end plate 33, the engagement is for preventing entanglement. It is solved immediately by the guide surface 54a.

  As described above, according to this example, the entrainment prevention plate 53 partially blocks the gap B between the front end plate 33 and the feeding roller 40, so that the check 6 is not drawn into the gap B. Further, since the entrainment preventing plate 53 extends between the outer peripheral surface portion 41 c of the roller main body 41 and the outer peripheral surface portion 42 a of the small diameter portion 42, the check 6 has an outer peripheral surface portion of the entrainment preventing plate 53 and the roller main body 41. It does not slip through the gap 41c and is not drawn into the gap B.

  In addition, since the entrainment prevention plate 53 of the present example has a predetermined width dimension in the axial direction of the feed roller 40, it is possible to reliably prevent the check 6 that collides therewith from being drawn into the gap B. Can do.

  Further, since the small diameter portion 42 is formed in the vicinity of the upper end portion 41 a where the feeding projection 43 is formed, the entrainment prevention plate 53 closes the gap B at a position close to the feeding projection 43. Yes. Since the check 6 is easily drawn into the gap B by engaging with the feeding protrusion 43, it is ensured that the check 6 is drawn into the gap B if the gap B is sealed at such a position. Can be prevented.

(Other embodiments)
In the above example, the feeding roller 40 has one small-diameter portion 42. However, a plurality of small-diameter portions 42 may be provided at positions separated in the axial direction. In this case, the front end plate 33 may be provided with the number of the entrainment preventing plates 53 corresponding to the small diameter portion 42.

  In the above example, the entanglement preventing plate 53 is attached so as to extend in parallel with the front end surface 33a. However, the entanglement preventing plate 53 is in the direction perpendicular to the axial direction of the feeding roller 40. You may attach so that it may incline toward the inclination guide surface 36 side. Also in this case, the front end 53a of the entrainment prevention plate 53 is attached so as to reach between the outer peripheral surface of the roller body 41 and the outer peripheral surface of the small-diameter portion 42.

  The present invention can also be used as a storage device for a medium processing apparatus for processing sheet-like media other than checks such as checks, bills, and bills. For example, it can be used as a sheet medium storage device mounted on a medium processing apparatus such as a printer or a scanner.
