Description

  The present invention relates to a printing apparatus that conveys paper sheets and performs printing processing.

  2. Description of the Related Art Conventionally, a passbook slip printer that prints on a passbook, a certificate, and a slip is used in a counter service of a financial institution such as a bank. A printing apparatus that prints these passbooks, certificates, and slips (hereinafter referred to as “medium”) includes a printing mechanism for printing on a medium and a medium conveyance path for conveying the medium. Since the medium is paper, paper jams are unavoidable. For this reason, internal mechanisms such as the print head and the medium conveyance path can be opened and closed for removing the jammed medium. . These internal mechanisms are also opened and closed during cleaning work and ink ribbon replacement work.

  After such work, when closing the internal mechanism part, if the internal mechanism part is locked halfway, so-called half-locked state of the internal mechanism part, printing will be hindered, and the medium cannot be conveyed correctly, etc. Problems occur. Further, when the internal mechanism portion is in the half-locked state, the cover of the apparatus is closed, causing a problem that the operator is not aware of this.

  Therefore, there is also a technology for controlling the apparatus not to operate when it is detected that the internal mechanism is not completely closed by providing a sensor or switch for detecting the opening / closing of the internal mechanism in the internal mechanism. .

  JP-A-2009-248316 (Patent Document 1) describes a recording apparatus that allows a user to recognize a half-open state of a carriage cover. According to Patent Document 1, a detection member is interposed between the carriage cover and the printer cover so that the printer cover is half-opened when the carriage cover is half-opened.

JP 2009-248316 A

  However, according to the prior art, when the operator notices that the internal mechanism portion is in the half-locked state, the operator needs to perform troublesome work such as opening the cover again and closing the internal mechanism portion. Even if a sensor for detecting the opening / closing of the internal mechanism is provided, the internal mechanism is almost closed when the internal mechanism is in the half-locked state. there were. Further, even if a protrusion is provided on the cover of the apparatus to be brought into contact with the internal mechanism portion so that the cover is not closed, the protrusion may not come into contact with the internal mechanism portion, and there is a case where there is no certainty.

  The problem to be solved by the present invention is to detect the half-locked state of the internal mechanism part without erroneous detection, and to make the operator notice the half-locked state of the internal mechanism part at the stage of closing the cover of the device. It is an object of the present invention to provide a printing apparatus capable of performing the above.

In order to solve the above-described problems, a printing apparatus according to the present invention includes an upper cover that can be opened and closed with respect to a main body, an internal mechanism that opens and closes when the upper cover is in an open state, and an opening and closing lever that opens and closes the internal mechanism. the has a first projection provided on the inner side of the upper cover, the open-close lever place the tip on the upper cover side, to the tip, the upper cover when the internal mechanism is half-locked state A belt- like portion that interferes with the first protrusion and prevents the interference with the first protrusion when the upper cover is closed when the internal mechanism is in a locked state. It is characterized by having.

  According to the present invention having the above-described configuration, the opening / closing lever for opening / closing the internal mechanism portion has its tip disposed on the upper cover side, and provided at the tip inside the upper cover when the internal mechanism portion is in a half-locked state. In addition, since the belt-shaped portion that interferes with the first protrusion is provided, it can interfere with the first protrusion in a wide range. Therefore, the half-lock state of the internal mechanism can be reliably detected without erroneous detection.

  Further, since the upper cover can be prevented from being closed by the action of the belt-shaped portion that interferes with the first protrusion when the upper cover of the printing apparatus is closed, the operator can be aware of the half-locked state of the mechanism portion. It is possible to provide a printing apparatus that can

(First embodiment)
First, the configuration of the passbook slip printer 100 according to the first embodiment of the present invention will be described. FIG. 2 is an external view of the passbook slip printer 100 according to the first embodiment. On the front face of the passbook slip printer 100 as a printing apparatus, there is a medium insertion port discharge port 21 through which an operator inserts a medium. In addition, an operation unit 22 on which an operator operates buttons and the like is provided on the front surface of the passbook slip printer 100. Furthermore, the passbook slip printer 100 has a main body cover 2 that covers the lower half of the main body of the apparatus and an upper cover 3 that can be opened and closed in the direction of arrow C in the figure.

  FIG. 3 is a schematic configuration diagram of the passbook slip printer 100 according to the first embodiment. The medium insertion port discharge port 21 receives a medium set by an operator, takes in the set medium, and discharges the medium after the printing process is completed. A medium transport path 23 is provided following the medium insertion opening / discharge port 21, and a plurality of transport roller pairs 24 that sandwich and transport the medium are disposed in the medium transport path 23. The printing unit 5 as an internal mechanism unit is mounted behind the medium insertion port discharge port 21. The printing unit 5 has a printing function on a medium and a printed line detection function for printing. Therefore, the printing unit 5 includes a printing head 8 that performs printing, a platen 25 that is disposed to face the printing head 8, an ink ribbon cartridge 9, and a reading unit (not shown). The reading unit reads a passbook page mark as a medium, a printed line, or a printed line of a slip.

  When the operator inserts a medium into the medium insertion port discharge port 21, the inclination of the medium is corrected by a not-shown width adjusting roller. Then, the passbook slip printer 100 transports the medium to the printing unit 5 by the transport roller pair 24. The print head 8 performs printing on the medium conveyed on the platen 25.

  FIG. 1 is an explanatory diagram showing the mechanism of the passbook slip printer 100 according to the first embodiment. The figure shows a state where the main body cover 2 and the upper cover 3 are omitted and the printing unit 5 is closed. The mechanism section body 4 is provided with the medium transport path 23, the pair of transport rollers 24, the platen 25, and the like, and the mechanism section body 4 is not opened and closed. The printing unit 5 is provided with a carriage shaft (not shown) provided in the direction perpendicular to the paper surface, that is, in the width direction with respect to the medium conveyance direction. A print head 8 is provided so as to be movable along the carriage shaft, and an ink ribbon cartridge 9 that moves integrally with the print head 8 is provided. The platen 25 is provided in the entire width direction with respect to the medium transport direction, whereby printing can be performed on the medium transported to the printing unit 5.

  The printing unit 5 is supported by the mechanism unit body 4 so as to be openable and closable by being coupled to a printing unit fulcrum 51 provided behind the mechanism unit body 4. In the printing unit 5, the print head 8, the ink ribbon cartridge 9, and the like are opened and closed together. Further, a lock lever 10 as an opening / closing lever for opening and closing the printing unit 5 is supported so as to be rotatable around a lever fulcrum 11 provided in the printing unit 5. Furthermore, a cam-like slit 12 is formed below the lock lever 10, and a post 41 provided on the mechanism body 4 is provided to be movable in the cam-like slit 12 as will be described later.

  FIG. 4 is an explanatory view showing the mechanism of the passbook slip printer 100 according to the first embodiment. The figure shows a state in which the printing unit 5 is opened. The operator operates to tilt the upper part of the lock lever 10 in the direction of arrow A. The post 41 provided on the mechanism main body 4 moves in the direction of the slit left end 12 b of the cam-shaped slit 12. Then, since the distance between the post 41 and the lever fulcrum 11 increases, the printing unit 5 rotates in the direction of arrow E around the printing unit fulcrum 51.

  Since the printing unit 5 can be opened in this manner, the operator can perform a paper jammed medium removing operation, a cleaning operation, or an ink ribbon replacement operation. After the completion of these operations, the operator can operate the upper part of the lock lever 10 in the reverse direction of the arrow A to return the printing unit 5 in the reverse direction of the arrow E.

  FIG. 5 is an explanatory diagram showing details of the lock lever 10 according to the first embodiment, and FIG. 6 is a perspective view of the lock lever 10 according to the first embodiment. The lock lever 10 is used to open and close the printing unit 5 and is substantially L-shaped. A lever fulcrum 11 is provided at the center of the lock lever 10 and is fixed to the printing unit 5 and rotates around the lever fulcrum 11. A handle 13 is formed on the upper portion of the lock lever 10, and the cam-shaped slit 12 is formed on the lower portion. A post 41 provided on the mechanism body 4 is fitted in the cam-like slit 12.

The cam-shaped slit 12 has a slit right end 12a and a slit left end 12b, both of which are formed in a curved shape so that the distances D1 to D2 from the lever fulcrum 11 gradually increase. More specifically, if the distance between the lever fulcrum 11 and the slit right end 12a is D1, and the distance between the lever fulcrum 11 and the slit left end 12b is D2, then D1 <D2. Accordingly, when the lock lever 10 is tilted in the direction of arrow A from the position shown in FIG. Move in the 12b direction. Then, since the distance between the post 41 and the lever fulcrum 11 increases, the printing unit 5 rotates around the printing unit fulcrum 51 in the direction of arrow E (see FIG. 4). That is, the printing unit 5 can be opened.

  Note that the cam-like slit 12 forms a small curved portion 12c so that the distance from the lever fulcrum 11 is slightly short just before the slit right end 12a. Accordingly, when the post 41 moves from the slit left end 12b to the slit right end 12a, the slit 41 reaches the slit right end 12a by crossing the small curved portion 12c. Therefore, the slit right end 12a is set to the locked position of the printing unit 5 in the closed state. Can do. On the other hand, when the post 41 is stopped at a position where the post 41 does not exceed the small curved portion 12c or a position near the small curved portion 12c, the printing unit 5 is in a half-locked state. (Hereinafter, the state of the lock lever 10 that creates the half-locked state of the printing unit 5 is referred to as the half-locked state of the lock lever 10)

  A handle 13 at the upper part of the lock lever 10 has a sawtooth portion 13-1 as a slip stopper, and a band-like portion 14 is formed at the upper end thereof. When the lock lever 10 is in a half-locked state, the belt-like portion 14 interferes with a first protrusion 31 provided on the inner side of the upper cover 3 described later. Accordingly, the belt-like portion 14 has a belt-like shape extending in the moving direction indicated by the arrows A and B of the handle 13 at the top of the lock lever 10. In other words, the belt-like portion 14 is formed in a circumferential shape with respect to the lever fulcrum 11 of the lock lever 10. Since the belt-like portion 14 has a belt-like shape extending in the moving direction of the handle 13, it can interfere with the first protrusion 31 in a wide range. That is, the half-locked state of the printing unit 5 can be widely covered. Reference numeral 15 denotes a plate-like reinforcing member that reinforces the belt-like portion 14.

  When the lock lever 10 passes the half-lock state and further rotates the lock lever 10 in the direction of arrow B, the post 41 enters the slit right end 12a as the lock position, and the printing unit 5 is locked.

  7 and 8 are explanatory views showing the relationship between the upper cover 3 and the lock lever 10, FIG. 7 shows a state in which the upper cover 3 is closed, and FIG. 8 shows a state in which the upper cover 3 is not yet completely closed ( Unclosed state). The upper cover 3 opens and closes around the cover fulcrum 33 of the coupling portion of the main body cover 2 (not shown in both drawings), and the first protrusion is located inside the upper cover 3 and at a position corresponding to the lock lever 10. 31 is arranged. A second protrusion 32 is disposed at a position away from the distance between the cover fulcrum 33 and the first protrusion 31 and is hooked on the photosensor 7 attached to the main body cover 2. In this way, the photo sensor 7 detects opening and closing of the upper cover 3. In addition, this photosensor 7 may be attached to the mechanism part main body 4 which does not open and close.

  The state where the upper cover 3 is closed as shown in FIG. 7 is the state where the printing unit 5 is closed as shown in FIG. In this state, the post 41 enters the slit right end 12a of the lock lever 10, the printing unit 5 is locked, and the lock lever 10 is maintained substantially vertical. In this state, when the operator rotates the upper cover 3 in the direction of arrow F and closes the upper cover 3, the first protrusion 31 of the upper cover 3 is located at a position adjacent to the belt-like portion 14 of the lock lever 10. Become. The second protrusion 32 of the upper cover 3 is engaged with the photosensor 7, and the photosensor 7 outputs an electrical signal indicating that the upper cover 3 is closed.

  When the upper cover 3 is not closed as shown in FIG. 8, the printing unit 5 is in a half-locked state. In this state, the post 41 has not yet entered the slit right end 12a of the lock lever 10, and the printing unit 5 is not locked. Therefore, the lock lever 10 is tilted slightly to the left (backward) from the vertical. In this state, when the operator rotates the upper cover 3 in the direction of arrow F and attempts to close the upper cover 3, the first protrusion 31 of the upper cover 3 is interfered with the belt-like portion 14 of the lock lever 10, and the upper The cover 3 is not closed. The second protrusion 32 of the upper cover 3 is not hooked on the photosensor 7, and the photosensor 7 outputs an electrical signal indicating that the upper cover 3 is not closed.

  Next, the operation of the passbook slip printer 100 relating to the first embodiment will be described. When performing the operation of removing the jammed medium or the operation of replacing the ink ribbon, the operator first opens the upper cover 3. Next, a hand is put on the handle 13 of the lock lever 10 to rotate it in the direction of arrow A. Since the lock lever 10 rotates around the lever fulcrum 11, the post 41 moves in the cam-shaped slit 12. Thus, the printing unit 5 is opened.

  After the operator removes the jammed medium or replaces the ink ribbon, the operator holds the handle 13 of the lock lever 10 and rotates it in the arrow B direction. Then, conversely, the printing unit 5 is closed. At this time, when the slit right end 12a of the cam-like slit 12 and the post 41 are not aligned and stopped before that as shown in FIG. 8, that is, when the printing unit 5 is in a half-locked state, the handle 13 is also vertical. It will be in a state of leaning back a little.

  If the upper cover 3 is to be closed in this state, the first protrusion 31 interferes with the band-like portion 14 of the handle 13 and the upper cover 3 cannot be closed. Further, since the upper cover 3 is not completely closed, the opening side is floating, and the second protrusion 32 is not detected by the photosensor 7.

  For this reason, even if an attempt is made to operate the printing process later on the passbook slip printer 100, the apparatus does not operate. Since the position of the photosensor 7 is far from the cover fulcrum 33, the amount of opening is large, so that even a slight interference with the second protrusion 32 is easy to detect.

  Even if the lock lever 10 is stopped further forward, the handle 13 of the lock lever 10 is formed with the band-like portion 14, so that it interferes with the first protrusion 31 of the upper cover 3 and the upper cover 3 is not yet attached. It can be in a closed state. Further, when the lock lever 10 is stopped further forward, the first protrusion 31 and the belt-like portion 14 do not interfere with each other, but the upper cover 3 interferes with the printing portion 5 itself because the printing portion 5 is wide open. It will not close.

  As described above in detail, according to the first embodiment, the belt-like portion 14 that interferes with the first protrusion 31 of the upper cover 3 is provided on the lock lever 10, and the printing portion 5 is in a half-locked state. In this case, since the upper cover 3 is not closed, the operator can be notified of the half-locked state. Even if the operator is not aware, the photo sensor 7 can detect that the upper cover 3 is not closed, so that the passbook slip printer 100 does not operate and does not induce a malfunction.

  Further, the belt-like portion 14 where the lock lever 10 interferes with the upper cover 3 has a belt-like shape extending in the rotation direction of the lock lever 10, so that it can interfere with the first protrusion 31 in a wide range and wide. The upper cover 3 can be prevented from closing in the half-locked state of the range, and the half-locked state of the printing unit 5 can be reliably detected.

(Modification of the first embodiment)
In the first embodiment, as shown in FIG. 7, when the printing unit 5 is closed, when the upper cover 3 is closed, the first protrusion 31 is located adjacent to the belt-like part 14 of the lock lever 10. Become. The present embodiment is not limited to this, and a hole 16 that does not interfere with the first protrusion 31 is provided in the middle of the belt-shaped portion 14 of the lock lever 10 so that the first protrusion 31 can be accommodated in the hole 16. Good.

  FIG. 9 is an explanatory diagram showing the relationship between the upper cover 3 and the lock lever 10 according to a modification of the first embodiment. The figure shows a state in which the printing unit 5 is closed. In this state, the post 41 enters the slit right end 12a of the lock lever 10, the printing unit 5 is locked, and the lock lever 10 is maintained substantially vertical. In this state, when the operator rotates the upper cover 3 in the direction of arrow F and closes the upper cover 3, the first protrusion 31 of the upper cover 3 is in the middle of the belt-shaped portion 14 of the lock lever 10. It fits in the hole 16 provided so as not to interfere with 31. Here, the hole 16 has a diameter sufficient to accommodate the first protrusion 31.

  The second protrusion 32 of the upper cover 3 is engaged with the photosensor 7, and the photosensor 7 outputs an electrical signal indicating that the upper cover 3 is closed. Even if comprised in this way, the effect similar to 1st Embodiment is acquired.

(Second Embodiment)
Next, the bankbook slip printer 100 relating to the second embodiment will be described. In the present embodiment, when the printing unit 5 is in a half-locked state as in the first embodiment, the upper cover 3 is not closed, and thereafter, the force is applied to the upper cover 3 in a further closing direction. In addition, the lock lever 10 is rotated so that the printing unit 5 is closed. Therefore, the belt-like portion slope 17 is continuously provided on the belt-like portion 14 that interferes with the first protrusion 31 of the upper cover 3, and the first protrusion 31 and the belt-like portion slope 17 are engaged.

  Since the configuration of the passbook slip printer 100 relating to the second embodiment is the same as that of the first embodiment, description thereof is omitted. The difference from the first embodiment is the shape of the lock lever 10.

  FIG. 10 is an explanatory diagram showing the lock lever 10 according to the second embodiment. The lock lever 10 is used to open and close the printing unit 5 and is substantially L-shaped. A lever fulcrum 11 is provided at the center of the lock lever 10 and is fixed to the printing unit 5 and rotates around the lever fulcrum 11. A handle 13 is formed at the upper part of the lock lever 10, and a cam-like slit 12 is formed at the lower part. A post 41 provided on the mechanism body 4 is fitted in the cam-like slit 12.

  The cam-shaped slit 12 has a slit right end 12a and a slit left end 12b, both of which are formed in a curved shape so that the distances D1 to D2 from the lever fulcrum 11 gradually increase. More specifically, if the distance between the lever fulcrum 11 and the slit right end 12a is D1, and the distance between the lever fulcrum 11 and the slit left end 12b is D2, then D1 <D2. Accordingly, when the lock lever 10 is tilted in the direction of arrow A from the position shown in FIG. 1, that is, from the position where the printing unit 5 is closed, the post 41 provided on the mechanism unit body 4 moves from the slit right end 12a of the cam-shaped slit 12 to the slit left end. Move in the 12b direction. Then, since the distance between the post 41 and the lever fulcrum 11 increases, the printing unit 5 rotates around the printing unit fulcrum 51 in the direction of arrow E (see FIG. 4). That is, the printing unit 5 can be opened.

  The slit 12 forms a small curved portion 12c so that the distance from the lever fulcrum 11 is slightly short just before the slit right end 12a. Therefore, when the post 41 moves from the slit left end 12b to the slit right end 12a, it reaches the slit right end 12a by exceeding the small curved portion 12c, so that the slit right end 12a can be set to the locked position.

  A handle 13 at the upper part of the lock lever 10 has a sawtooth portion 13-1 as a slip stopper, and a band-like portion 14 is formed at the upper end thereof. The belt-like portion 14 interferes with the first protrusion 31 provided on the inner side of the upper cover 3 when the lock lever 10 is in a half-locked state. Accordingly, the belt-like portion 14 has a belt-like shape extending in the moving direction indicated by the arrows A and B of the handle 13 at the top of the lock lever 10. Since the belt-like portion 14 has a belt-like shape extending in the moving direction of the handle 13, the angle of the lock lever 10 is wide and can interfere with the first protrusion 31. That is, the half-locked state of the printing unit 5 can be widely covered.

  Furthermore, the belt-shaped part slope 17 which is the characteristic of this Embodiment is provided continuously in the arrow A direction of the belt-shaped part 14. The belt-shaped portion inclined surface 17 interferes with the first protrusion 31 provided on the inner side of the upper cover 3 when the lock lever 10 is in the half-locked state. That is, the first protrusion 31 of the upper cover 3 is arranged at a position in contact with the belt-shaped portion inclined surface 17. In this state, when the operator applies a force in the closing direction to the upper cover 3, the lock lever 10 is rotated in the arrow B direction so that the printing unit 5 is closed. Reference numeral 15 denotes a plate-like reinforcing member that reinforces the belt-like portion 14.

  When the lock lever 10 passes the half-lock state and further rotates the lock lever 10 in the direction of arrow B, the post 41 enters the slit right end 12a as the lock position, and the printing unit 5 is locked.

  Next, the operation of the passbook slip printer 100 relating to the second embodiment will be described. When the printing unit 5 is in the half-locked state, the operation for preventing the upper cover 3 from being closed and the operation for detecting that the upper cover 3 is not closed by the photosensor 7 are the same as those in the first embodiment. Since there is, description is abbreviate | omitted.

  As an operation of the present embodiment, it is assumed that the lock lever 10 is stopped a little before the lock lever 10 is completely locked. When the upper cover 3 is closed in this state, the first protrusion 31 comes into contact with the belt-shaped portion slope 17 of the lock lever 10. Since the upper cover 3 interferes with the belt-shaped portion inclined surface 17 and does not completely close, this can inform the operator that the upper cover 3 will not close.

  At this time, the operator performs further closing operation in the direction of arrow F until the upper cover 3 is completely closed. Then, the first protrusion 31 pushes the belt-like portion inclined surface 17 of the lock lever 10, and the lock lever 10 rotates in the arrow B direction. As a result, the lock lever 10 is set to a position where the lock lever 10 is completely locked, and the printing unit 5 is closed.

  As described above, according to the second embodiment, the same effects as those of the first embodiment can be obtained, and printing can be performed without opening the upper cover 3 again when the printing unit 5 is in the half-locked state. The part 5 can be brought into a closed state, and there is an effect that a troublesome operation can be omitted.

(Modification of the second embodiment)
In the present embodiment, the belt-like portion slope 17 is provided continuously from the belt-like portion 14 of the lock lever 10, but instead of providing the belt-like portion slope 17, the first protrusion 31 of the upper cover 3 is inclined toward the lock lever 10 side. Providing the portion 34 has the same effect. FIG. 11 is an explanatory view showing the first protrusion 31 of the upper cover 3 according to a modification of the second embodiment. The inclined portion 34 provided on the first protrusion 31 is configured to interfere with the end portion 14-1 of the band-shaped portion 14.

  As an operation of the present modification, it is assumed that the lock lever 10 is stopped just before the lock lever 10 is completely locked. In this state, when the upper cover 3 is closed, the inclined portion 34 of the first protrusion 31 contacts the end portion 14-1 of the belt-like portion 14 of the lock lever 10. Since the upper cover 3 interferes with the end portion 14-1 of the belt-like portion 14 and does not completely close, this can inform the operator that the upper cover 3 will not close.

  At this time, the operator performs further closing operation in the direction of arrow F until the upper cover 3 is completely closed. Then, the inclined portion 34 of the first protrusion 31 pushes the end portion 14-1 of the belt-like portion 14 of the lock lever 10, and the lock lever 10 rotates in the direction of arrow B. As a result, the lock lever 10 is set to a position where the lock lever 10 is completely locked, and the printing unit 5 is closed.

  In the case of this modification, the diameter of the first protrusion 31 is larger than that of the second embodiment, and the strength needs to be increased. Further, the angle of the tip of the inclined portion 34 of the first protrusion 31 is desirably 30 degrees to 40 degrees. Thereby, also by this modification, the effect similar to 2nd Embodiment can be acquired.
