Description

  The present invention relates to a date stamp typified by a reception stamp, a receipt stamp, an inspected stamp, etc., and in particular, a date stamp provided with a replacement stamp for printing a stamper's name or employee number on a fixed printed body. .

  This type of date stamp is known from US Pat. There, a main body, a fixed printing body that is slidably mounted on the lower part of the main body part, a printing unit that is housed in the main body part, a grip that is mounted on the upper part of the main body part, and a detachable attachment to the fixed printing body The date stamp is made up of a replacement stamp. The fixed printing body can change the posture between the stamping position and the date changing position, and the date can be changed by moving the printing belt of the printing unit while the fixed printing body is moved to the date changing position.

  The replacement mark is composed of a rubber printing body and a holder (support), and a mounting portion is provided on the lower back surface of the outer frame constituting the main body portion for attaching and detaching the replacement mark. Between the holder and the mounting portion, there are provided first and second restricting structures that engage with each other to restrict the back-and-forth movement of the holder, and a left-right restricting structure that restricts left-right movement. By supporting the upper and lower sides and the left and right sides of the holder with these restriction structures, the replacement mark at the time of use is restricted from moving back and forth or left and right. The holder is provided with an adjustment screw. By adjusting the screwing amount of the adjustment screw, the height of the printing surface of the rubber printing body can be made to coincide with the height of the printing surface of the fixed printing body.

  When replacing the replacement mark, slide the fixed print body to the date change position to separate the fixed print body from the replacement mark, and then push down the entire replacement mark toward the fixed print body. To release the engagement between the holder and the rear wall of the outer frame. Finally, the replacement mark is pulled out of the outer frame while being inclined obliquely toward the outside of the mounting portion, and the replacement mark is removed from the main body. The new replacement mark is attached to the attachment portion along the reverse procedure of the above separation procedure. When adjusting the screwing amount of the adjusting screw, the adjusting screw is adjusted with the replacement mark displaced to the date change position in the same manner as described above.

  In the present invention, a main case that accommodates the printing unit and a cover cylinder that covers the outer surface of the main case constitute a main body case, and a date stamp (hereinafter referred to as a case built-in type) having a structure in which a fixed printing body is disposed at the lower end thereof. A replacement stamp is added to the date stamp), and the basic structure of this type of date stamp is known from Patent Document 2. The date stamp according to Patent Document 1 is used in a state where it is stood and stored in a stand, but the date stamp with a built-in case carries the date stamp easily because the printing surface of the fixed printing body is covered with the stamp cap. And can do storage work on the go.

JP2009-133201A (paragraph numbers 0037 to 0039, FIG. 4) Japanese Utility Model Publication No. 03-56372 (page 2, right column, line 41 to page 3, left column, line 3, FIG. 2)

  In the date stamp according to Patent Document 1, it is necessary to slide the fixed printing body to the date change position, push down the replacement mark in this state, and further remove the holder from the mounting portion while tilting it out of the mounting portion. For this reason, a series of procedures for exchanging the replacement mark is complicated, and much work is required for the replacement work of the replacement mark.

  When adjusting the height of the printed surface of the replacement printed rubber stamp, separate the replacement mark from the mounting position of the main unit and adjust the adjustment screw. It is necessary to perform the work of remounting to the main body and the work of confirming the adjustment result by performing trial marking. Therefore, it is good if the height of the printing surface of the replacement mark and the fixed printing body can be matched by a single height adjustment operation, but in most cases, it is necessary to repeat each operation several times. It takes time and effort. Further, although the replacement mark is restricted from upward movement via the adjusting screw, downward movement is not restricted. Furthermore, a part of the holder is always exposed on the outer surface of the outer frame. Therefore, a part of the holder exposed on the outer surface of the outer frame may collide with another object during use, and the rubber printing body of the replacement mark may move, and the printed characters may be blurred.

  It takes time to attach and detach the replacement mark and adjust the height of the print surface. Compared to the vertical dimension of the replacement mark, the main body and the fixed print body when the fixed print body is displaced to the date change position. This is because the vertical gap between them is small. In addition, the fixed printing body and the replacement mark are individually attached to the main body, and the height adjustment of the printing surface with respect to the fixed printing body of the replacement mark is performed via the main body, that is, indirectly. This is because the height of the printing surface for replacement is adjusted.

  In the date stamp according to Patent Document 1, an adjustment screw is screwed into a nut that is non-rotatably engaged with the holder to adjust the height of the marking surface of the rubber printed body. For this reason, when continuously stamping, the adjustment screw may move slightly due to the impact during the stamping, and as a result, the printed characters of the replacement mark slightly blur or fade during use. There was a fear.

  In most cases, a date stamp having a replacement stamp is configured as a date stamp having a structure disclosed in Patent Document 1, that is, a dial-exposed date stamp. There are no examples of marking in the past. This is because the outer surface of the printing unit is covered with the main case and the cover cylinder, and it is difficult to accommodate the replacement mark inside the main case while avoiding the rotation locus of the printing belt. However, when printing the name of the person in charge of stamping on a date stamp with a built-in case, it is necessary to replace the rubber printed body of the fixed printing body every time the person in charge of printing changes due to personnel changes. Yes, the cost for that will increase. Under such circumstances, a case-incorporated date stamp having a replacement stamp is expected in the occupational field where the case-incorporated date stamp is frequently used.

The present invention has been proposed on the basis of the above knowledge, and its purpose is to provide a date stamp provided with a replacement mark that is easy to use and can be easily replaced with less trouble. It is to provide.
The purpose of the present invention is to accurately adjust the height of the printing surface of the replacement mark, and to eliminate the fact that the printed characters of the replacement mark are blurred or blurred during use, so that the replacement printing can always be performed properly. To provide a date stamp with a mark.

The vertical height positions of the adjacent adjustment grooves 87 are gradually changed. By rotating the adjustment cylinder 85 around the fastening screw 89 and changing the adjustment groove 87 supported by the reference rib 81, the height of the printing surface of the name printing body 71 can be adjusted stepwise. .

  The fastening screw 89 is screwed into the screw boss 75 of the printing stand 73 through a screw insertion hole 80 formed in the base wall 78 of the holder 72. As shown in FIG. 15, a pair of adjustment grooves 87 provided in the adjustment cylinder 85 are supported by a pair of reference ribs 81 provided facing the opposing edges of the screw insertion hole 80.

  A regulating piece 88 is formed on the peripheral surface of the adjustment cylinder 85, and a stopper 82 is provided on the upper surface of the base wall 78 to receive the regulation piece 88 and define the adjustment limit of the adjustment cylinder 85.

  As shown in FIG. 2, the main body case 1 includes a main case 7 that accommodates the printing unit 2 and a cover cylinder 8 that covers the outer surface of the main case 7, and the date stamp is configured as a date stamp with a built-in case. To do. The fixed printing body 3 is attached to and detached from the main case 7 and can be changed in posture between an assembly posture attached to a lower portion of the main case 7 and a separation posture removed from the main case 7. The replacement mark 70 in a state in which the fixed printing body 3 is in the assembled posture is accommodated entirely in the main case 7 and is held unremovable. The replacement mark 70 is attached to and detached from the fixed print body 3 with the fixed print body 3 in the separation posture and the holder 72 exposed to the free space on the outer surface of the main case 7.

  The cover cylinder 8 in the case-embedded date stamp is supported by the main case 7 so that the posture can be changed between a closed posture that covers the outer surface of the main case 7 and an open posture that opens the outer surface of the main case 7. A lock structure is provided between the main case 7 and the cover cylinder 8 to restrict the operation of the cover cylinder 8 to the open posture. As shown in FIG. 10, the lock structure includes a lock unit 32 fixed to a fastening boss 16 provided on an end wall of the cover cylinder 8, a lock body 34 fixed to an operation shaft 33 of the lock unit 32, and a main case 7. And an engagement body 35 provided on the inner surface. In a state where the lock unit 32 constituted by the cylinder lock is locked by the key 36, the lock body 34 is engaged with the engagement body 35 and the cover cylinder 8 is restricted from being switched to the open position.

  The fixed printing body 3 includes a stamp face holder 26 and a rubber print body 27 fixed to the stamp face holder 26. The fixing claw 30 provided on the marking surface holder 26 is inserted into and engaged with the mounting hole 31 of the main case 7 from below, and the fixed printing body 3 is mounted on the main case 7. As shown in FIGS. 11 and 12, in the state where the cover cylinder 8 is closed and the lock unit 32 is locked with the key 36, the periphery of the attachment claw 30 is covered with the cover cylinder 8, and the attachment claw 30 and the attachment hole 31 are covered. The cover cylinder 8 prevents the engaged state from being released.

  As shown in FIG. 18, the main body case 1 includes a frame 102 that houses the printing unit 2, and a stamp base 103 that is slidably mounted on the lower end of the frame 102. It is configured as a mark. The fixed printing body 3 can be attached to and detached from the stamp table 103, and can be changed in posture between an assembly posture attached to the lower surface of the stamp table 103 and a separation posture removed from the stamp table 103. The replacement mark 70 in a state where the fixed printing body 3 is in the assembled posture is accommodated inside the frame 102 and is held unremovable. As shown in FIG. 20, the replacement mark 70 is attached to and detached from the fixed print body 3 with the fixed print body 3 in the separation posture and the holder 72 exposed to the free space on the outer surface of the frame 102.

  As shown in FIG. 21, the main body case 1 includes a frame 102 that accommodates the printing unit 2 and a stamp base 103 that is attached to the lower end of the frame 102, and the date mark is configured as a dial-exposed date mark. It is. The fixed printing body 3 is fixed to the lower surface of the stamp table 103. The frame 102 and the stamp stand 103 are connected via a connecting shaft 115 that penetrates both. The fixed printing body 3 and the stamp base 103 are supported by the frame 102 so as to be vertically slidable and swingable around the connecting shaft 115, and the mounting posture in which the stamp base 103 is mounted on the lower end of the frame 102; The posture can be changed to the separation posture in which the stamp table 103 is detached from the frame 102. The replacement mark 70 in the state in which the stamp stand 103 is in the assembled posture is accommodated inside the frame 102 and is held unremovable. The replacement mark 70 is attached to and detached from the fixed printing body 3 in a state in which the stamp stand 103 is set in the separation posture and the holder 72 is exposed to the free space on the outer surface of the frame 102.

  In the present invention, the fixed printing body 3 can be changed in posture with respect to the main body case 1 between an assembly posture and a separation posture. Further, the replacement mark 70 is detachably attached to the peripheral wall of the replacement window 29 of the fixed print body 3 so that the entire replacement mark 70 is supported by the fixed print body 3. In addition, the fixed printing body 3 is set in a separation posture so that the replacement mark 70 can be attached to and detached from the fixed printing body 3 with the holder 72 exposed to the free space on the outer surface of the main body case 1.

  As described above, when the replacement mark 70 is attached to the peripheral wall of the replacement window 29 and the replacement mark 70 is attached to and detached from the fixed printing body 3 with the holder 72 exposed to the free space, the main body case 1 is disturbed. Without replacement, the replacement mark 70 can be easily attached to and detached from the fixed printing body 3. Accordingly, it is possible to provide a date stamp provided with a replacement mark that allows the replacement mark 70 to be easily exchanged with less effort compared to a conventional date stamp provided with a replacement mark. Further, in the state in which the fixed printing body 3 is in the assembled posture, the entire replacement mark 70 is accommodated inside the main body case 1 and is held unremovable. Appropriate printing can always be performed by eliminating the blurring or fading of the printed characters of the replacement mark 70 due to a collision. There is also an advantage that the impression of the appearance of the date stamp in the use state can be made clear.

  According to the detachable structure in which the base wall 78 and the plurality of engagement legs 79 constitute the holder 72 and the engagement legs 79 and the engagement holes 91 around the replacement window 29 are the engagement elements, the engagement legs 79 are engaged. The replacement mark 70 can be easily fixed to the fixed printing body 3 simply by being inserted into and engaged with the fitting hole 91. Furthermore, the replacement mark 70 can be easily removed from the fixed print body 3 simply by operating the engagement leg 79 to release the engagement state with the engagement hole 91. Therefore, the attaching / detaching operation of the replacement mark 70 with respect to the fixed printing body 3 can be performed easily and accurately with less effort compared to the date stamp provided with the conventional replacement mark. Further, in a state where the replacement mark 70 is mounted on the fixed printing body 3, there is no room for the replacement mark 70 to move freely, so that the printed characters of the replacement mark 70 can be more surely blurred or blurred during use. Preventing it, you can always print properly.

  If a height adjustment structure for adjusting the height of the printing surface of the name printing body 71 is provided between the name printing body 71 and the fastening screw 89, or between the holder 72 and the fastening screw 89, the replacement mark 70 is provided. It is possible to perform the height adjustment work quickly without significantly reducing the labor required for the height adjustment. When the height is adjusted, the replacement mark 70 can be directly attached to the fixed print body 3 and the adjustment result can be confirmed by performing a trial seal immediately after the adjustment. This is because a series of height adjustment operations can be performed accurately with less effort. With this type of date stamp in the past, it was necessary to re-install the replacement mark after adjustment on the main body and then perform trial stamping, but this effort is not required at all. The height adjustment structure provided between the holder 72 and the fastening screw 89 is illustrated in FIG. 15, and the height adjustment structure provided between the name printing body 71 and the fastening screw 89 is illustrated in FIG. doing.

  According to the height adjustment structure in which the adjustment cylinder 85 is rotated around the fastening screw 89 to change the adjustment groove 87 supported by the reference rib 81, the height of the printing surface of the name printing body 71 is stepwise. Since the gradual increase or decrease can be adjusted, the height adjustment according to the result of the trial seal can be accurately performed. Further, the adjusted adjustment cylinder 85 is pressed downward by receiving the biasing force of the spring 86, and the adjustment groove 87 provided at the lower end of the cylinder wall is received by the reference rib 81. Can be reliably prevented from moving out of the proper adjustment position. Therefore, the adjustment cylinder 85 does not rotate due to an external force during use, and printing with the replacement mark 70 can always be performed properly.

  When the pair of reference ribs 81 are provided facing the opposing edges of the screw insertion holes 80, the pair of adjustment grooves 87 can be supported by the pair of reference ribs 81, and the adjustment cylinder 85 can be supported in a more stable state. Further, the pair of adjustment grooves 87 and the reference rib 81 are engaged with each other, and the adjustment cylinder 85 can be further reliably prevented from being displaced from the proper adjustment position.

  If the restricting piece 88 provided on the peripheral surface of the adjustment cylinder 85 is received by the stopper 82 provided on the upper surface of the base wall 78, the rotation of the adjustment cylinder 85 beyond the adjustment limit can be restricted. Accordingly, it is possible to prevent the adjustment cylinder 85 from greatly deviating from the appropriate adjustment range and performing an unnecessary adjustment operation, and the height adjustment of the printing surface of the replacement mark 70 can be easily performed within the appropriate adjustment range. It can be done accurately.

  In the case-incorporated date stamp, the main case 7 and the cover cylinder 8 constitute the main body case 1, and the fixed printing body 3 is attached to and detached from the main case 7. The posture can be changed. Further, the replacement mark 70 is detachably attached to the peripheral wall of the replacement window 29 of the fixed print body 3 so that the entire replacement mark 70 is supported by the fixed print body 3. In addition, the replacement print 70 can be attached to and detached from the fixed print body 3 in a state where the fixed print body 3 is set in the separation posture and the holder 72 is exposed to the free space on the outer surface of the main case 7.

  As described above, when the replacement mark 70 is attached to the peripheral wall of the replacement window 29 and the replacement mark 70 is attached to and detached from the fixed printing body 3 with the holder 72 exposed to the free space, the main case 7 is disturbed. Without replacement, the replacement mark 70 can be easily attached to and detached from the fixed printing body 3. Also, since the name of the person in charge of the stamp can be easily changed by replacing the replacement mark 70, it is possible to replace the rubber printing body 27 of the fixed printing body 3 as compared with the conventional case-incorporated date stamp. The cost associated with changing the name, etc. can be reduced and the usability of the date stamp with built-in case can be improved.

  The lock unit 32 formed of a cylinder lock, the lock body 34, the engagement body 35 and the like constitute a lock structure, and the lock unit 32 is locked according to the case built-in type date stamp in which the lock structure is incorporated in the main body case 1. It is possible to prevent the date from being changed illegally by simply making the cover cylinder 8 unopenable. When the date is changed by operating the print belt 24, the lock unit 32 is unlocked, the cover cylinder 8 is moved to the open position, and the adjustment dial 22 is exposed from the adjustment window 9. Often, date changes and adjustments can be made quickly and easily. Furthermore, since the overall weight increases by the amount of the cylinder lock by configuring the lock unit 32 with the cylinder lock, the impression when holding the date stamp with one hand is richer than the conventional date stamp. It is possible to appeal to the user that the date stamp has a high security function.

  When the mounting claw 30 provided on the marking surface holder 26 is inserted into the mounting hole 31 of the main case 7 from below and engaged with the cover cylinder 8, the mounting claw 30 is engaged with the mounting hole 31. The cover cylinder 8 can prevent the state from being released. Accordingly, it is possible to prevent the fixed printing body 3 from being separated from the main case 7 and the replacement mark 70 from being illegally replaced. In addition, it is possible to prevent the date from being changed illegally by rotating the print belt 24 directly from the exit / exit port 12 with the fixed print body 3 removed from the main case 7. In particular, in the case-embedded date stamp that restricts the opening operation of the cover cylinder 8 with a lock structure, it is possible to reliably prevent the fixed printed body 3 from being separated from the main case 7 and Unauthorized date changes can be reliably prevented.

  In the dial-exposed date stamp, the posture is changed between an assembly posture and a separation posture by providing a stamp base 103 at the lower end of the frame 102 constituting the main body case 1 and attaching / detaching the fixed printing body 3 to / from the stamp base 103. I was able to do it. Further, the replacement mark 70 is detachably attached to the peripheral wall of the replacement window 29 of the fixed print body 3 so that the entire replacement mark 70 is supported by the fixed print body 3. In addition, the replacement print 70 can be attached to and detached from the fixed print body 3 in a state where the fixed print body 3 is in the separation posture and the holder 72 is exposed to the free space on the outer surface of the frame 102.

  As described above, when the replacement mark 70 is attached to the peripheral wall of the replacement window 29 and the replacement mark 70 is attached to and detached from the fixed printing body 3 with the holder 72 exposed to the free space, the frame 102 is obstructed. Without replacement, the replacement mark 70 can be easily attached to and detached from the fixed printing body 3. Further, since the replacement mark 70 in the state where the fixed printing body 3 is in the assembled posture is entirely accommodated in the frame 102, the appearance of the date mark in the use state is compared with the conventional date stamp of this type. The impression of can be refreshed.

  In the dial exposure type date stamp in which the stamp base 103 is attached to the lower end of the frame 102 and the fixed print body 3 is fixed to the lower surface thereof, the fixed print body 3 and the stamp base 103 are assembled to the frame 102. The posture can be changed to the separated posture. Further, the replacement mark 70 is detachably attached to the peripheral wall of the replacement window 29 of the fixed print body 3 so that the entire replacement mark 70 is supported by the fixed print body 3. In addition, the fixed printing body 3 and the stamp base 103 are set in a separated posture so that the replacement mark 70 can be attached to and detached from the fixed printing body 3 with the holder 72 exposed to the free space on the outer surface of the frame 102. .

  As described above, when the replacement mark 70 is attached to the peripheral wall of the replacement window 29 and the replacement mark 70 is attached to and detached from the fixed printing body 3 with the holder 72 exposed to the free space, the frame 102 is obstructed. Without replacement, the replacement mark 70 can be easily attached to and detached from the fixed printing body 3. Further, even when the stamp stand 103 is in the separated posture, the stamp stand 103 remains connected to the frame 102 by the connecting shaft 115, so that when the stamp stand 103 is assembled to the frame 102, the assembly posture and orientation The stamp table 103 can be properly assembled to the frame 102.

It will be in a state where it can move upward. By opening the cover cylinder 8 in this state, the printing unit 2 is pushed up to the date changing position by the spring 25, and the lower part of the printing belt 24 is pulled out from the date window 28 and the exit / exit port 12. The printing belt 24 can be rotated. Note that the lower end of the cover cylinder 8 at the above-mentioned closed position (open restriction position) is received by a flange wall provided at the lower part of the main case 7.

  The height adjustment structure includes an adjustment ring (adjustment body) 54 and a relay frame 55 that transmits the adjustment operation of the adjustment ring 54 to the frame 20 of the printing unit 2. The adjustment ring 54 is disposed above the lock body 34, and the relay frame 55 is disposed between the lock body 34 and the frame 20 of the printing unit 2. In FIG. 5, the adjustment ring 54 is made of a plastic product having a circular ring shape, and a group of non-slip ribs 56 is formed on the entire peripheral surface. A recess 57 for receiving the first nut 44 is formed on the inner surface of the adjustment ring 54, and a female screw 58 is formed on the inner surface of the ring below the recess 57. In order to rotate the adjustment ring 54, a pair of operation windows 59 are opened on the left and right of the peripheral wall of the fastening boss 16. The height adjustment of the printing unit 2 can be easily performed by gripping the anti-slip rib 56 exposed from the operation window 59 with a fingertip and rotating the adjustment ring 54.

  The adjustment ring 54 is supported by the shaft portion 40 of the lock case 37 so that it can be adjusted up and down by screwing the female screw 58 into the male screw 41 of the lock case 37 (see FIG. 8). As described above, when the adjustment ring 54 is supported by the shaft portion 40 so as to be movable up and down using the male screw 41 provided on the shaft portion 40 of the lock case 37, it is not necessary to separately provide a screwing counterpart of the adjustment ring 54. Therefore, it is possible to prevent the height adjustment structure from becoming complicated. Further, since the male screw 41 formed on the shaft portion 40 is a fine screw, the vertical adjustment amount per rotation when the adjustment unit 54 is rotated to move the printing unit 2 can be reduced. Furthermore, since the adjustment ring 54 is screwed into the male screw 41 that is precisely formed by metal processing, the adjustment ring 54 screwed into the shaft portion 40 can be prevented from rattling up and down, and the overall marking surface height of the printing unit 2 can be reduced. Adjustment can be made precisely. In addition, since the lock unit 32 and the adjustment ring 54 are arranged concentrically, a lock structure and a height adjustment structure are provided on the upper inner surface of the cover cylinder 8 in a state in which the space occupied by the both 32 and 54 is eliminated. Centralized arrangement is possible.

Further, the lock unit 32, the lock body 34, and the adjustment ring 54 are assembled in advance to the cover cylinder 8, and the lock unit 32 is unlocked with the key 36 before the cover cylinder 8 is assembled to the main case 7. After the printing unit 2 with the relay frame 55 assembled is assembled with the spring 25 in the main case 7, the cover cylinder 8 is assembled with the main case 7, and the passive piece 63 engages with the relief groove 50. Thus, the regulation leg 65 of the relay frame 55 is engaged with the adjustment window 9. In this assembled state, the passive piece 63 protrudes upward from the main body 48 via the escape groove 50 and contacts the lower surface of the adjustment ring 54 (see FIG. 8). The lock body 34 can rotate relative to the relay frame 55 within the clearance groove 50. Therefore, when the lock body 34 is rotated by the key 36, the passive piece 63 that does not rotate and the main body 48 that rotates. Can be prevented from interfering with each other.

  As described above, when the lock structure and the height adjustment structure are collectively arranged on the upper surface of the cover cylinder 8, the upper end surface of the lock unit 32 and the keyhole 42 are exposed on the upper surface of the fastening boss 16. Further, the anti-slip rib 56 and the operation window 59 of the adjustment ring 54 are exposed at two locations on the peripheral surface of the fastening boss 16, and the impression of the appearance of the date stamp is impaired. The upper cap 17 is provided in order to eliminate such problems in appearance and prevent foreign matter from entering the keyhole 42, and the cap 17 is detachably attached to the fastening boss 16. In order to maintain the mounting state of the upper cap 17, ribs that engage with each other are provided on the lower portion of the peripheral wall of the fastening boss 16 and the lower portion of the inner surface of the upper cap 17.

  Details of the replacement mark 70 are shown in FIGS. The replacement mark 70 includes a name printing body 71 for printing the name and employee number of the stamper, a holder 72 for mounting the name printing body 71 on the replacement window 29, and the name printing body 71 and the holder 72. It consists of a height adjustment mechanism or the like provided between them. In FIG. 13, the name printing body 71 includes a plastic printing board 73 and a rubber printing body 74 that is bonded and fixed to the lower surface of the printing board 73. Screw bosses 75 are formed on the upper surface of the printing stand 73, and positioning ribs 76 that also serve as rotation stoppers are formed on the left and right side surfaces.

  The holder 72 is formed of a portal-shaped plastic molded product integrally provided with a horizontally-long rectangular base wall 78 and four engagement legs 79 provided downward on the left and right sides of the base wall 78. A screw insertion hole 80 is formed in the center in a vertically penetrating manner. Reference ribs 81 having a triangular cross section constituting a height adjustment mechanism are provided on both the left and right sides of the screw insertion hole 80, and stoppers 82 are provided on the left and right sides of the rear edge of the base wall 78.

  The height adjusting mechanism includes a reference rib 81, an adjustment cylinder 85 supported by the reference rib 81, a compression coil spring 86 disposed between the holder 72 and the printing stand 73, and the adjustment cylinder 85. It comprises a group of adjustment grooves 87 formed at the lower end of the cylindrical wall. On the peripheral surface of the adjusting cylinder 85, a regulating piece 88 that is received by the previous stopper 82 is formed in a protruding manner. As shown in the development view of FIG. 16, each adjustment groove 87 is formed by cutting the lower end of the cylinder wall of the adjustment cylinder 85 into an inverted V shape so that each groove 87 continuously forms a groove row in the circumferential direction. It is formed. Twelve adjustment grooves 87 are formed at positions facing the cylinder wall of the adjustment cylinder 85, and the vertical height positions of the adjacent adjustment grooves 87 differ by 0.2 mm.

  By inserting a fastening screw (fastening screw) 89 inserted through the adjustment cylinder 85 into a screw insertion hole 80 of the base wall 78 and further screwing the screw shaft into the screw boss 75 of the printing stand 73, the name printing body 71. And the holder 72 are integrated. In this assembled state, as shown in FIG. 15, the lower surface of the operating head of the fastening screw 89 is supported by the upper end wall of the adjustment cylinder 85, and the pair of adjustment grooves 87 are stabilized by the pair of reference ribs 81. It is accepted. The name printing body 71 is biased to move downward by a spring 86 and is suspended and supported by a holder 72 via an adjustment cylinder 85 and a fastening screw 89.

  Positioning grooves 90 for receiving positioning ribs 76 are formed on the left and right sides of the replacement window 29, and four engagement holes 91 for engaging the engagement legs 79 are adjacent to the replacement window 29. It is formed. The engagement leg 79 and the engagement hole 91 constitute a connection structure for mounting the replacement mark 70 to the fixed print body 3.

  The replacement mark 70 is attached to and detached from the replacement window 29 from the upper surface side of the fixed print body 3 in a state where the fixed print body 3 is removed from the main case 7 and replaced. Specifically, after the fixed printing body 3 is removed from the main case 7, the engagement leg 79 of the replacement mark 70 attached to the replacement window 29 is elastically deformed in a direction approaching the left and right center to engage the engagement hole 91. And the replacement mark 70 is removed from the replacement window 29. Next, the name printed body 71 of the new replacement mark 70 is fitted into the replacement window 29 in a state where the positioning rib 76 and the positioning groove 90 are engaged, and the engagement leg 79 is further inserted into the engagement hole 91. The engaging claw is engaged with the step on the lower surface side of the engaging hole 91.

  When the height of the new replacement mark 70 that has been replaced is adjusted, first, the surface of the name print body 71 is printed with the ink printed on the print surfaces of the fixed print body 3 and the rubber print body 74. Check the marking status. In most cases, since the rubber printing body 27 of the fixed printing body 3 and the rubber printing body 74 of the name printing body 71 are different in production time, the printed character of the name printing body 71 is faint. , Often blurring. In any case, it is possible to determine whether the name print body 71 is adjusted to the direction in which the blur is corrected or the direction in which the blur is corrected is adjusted with respect to the print surface of the fixed print body 3 by trying the seal. it can.

  Next, the height of the printing surface of the name printing body 71 is adjusted by rotating the adjustment cylinder 85 left or right to change the adjustment groove 87 supported by the reference rib 81. For example, in the case of correcting the fading, the adjustment cylinder 85 is rotated in the clockwise direction in FIG. 14, and the adjustment groove 87 having a large groove depth is supported by the reference rib 81, thereby printing the name printing body 71. Lower the surface. That is, when the printing surface of the fixed printing body 3 is used as a reference, the printing surface of the name printing body 71 is moved to the side protruding from the printing surface of the fixed printing body 3. Further, when correcting the blur, the adjustment cylinder 85 is rotated in the counterclockwise direction, and the adjustment groove 87 having a small groove depth is supported by the reference rib 81, so that the printing surface of the name printing body 71 is changed. increase. That is, when the printing surface of the fixed printing body 3 is used as a reference, the printing surface of the name printing body 71 is moved to the side of retreating from the printing surface of the fixed printing body 3.

  In this embodiment, 12 pairs of 6 adjustment grooves 87 are provided, so that the total adjustment amount is 1.2 mm, and the height of the name printing body 71 can be adjusted within the range. Again, the seal is tried and the adjustment result is confirmed, and adjustment is performed until the state of characters printed on the name printing body 71 becomes a desired state. When performing height adjustment, when the adjustment groove 87 positioned at the start and end of the groove row is supported by the reference rib 81, that is, when the adjustment cylinder 85 is at the adjustment limit position, the adjustment cylinder 85 rotates beyond the adjustment limit. In order to prevent the operation, the regulating piece 88 is received by the stopper 82. In this way, if the stopper 82 restricts the adjustment cylinder 85 from being rotated beyond the adjustment limit, the adjustment cylinder 85 is prevented from being unnecessarily adjusted in a state of greatly deviating from the proper adjustment range. it can. Therefore, the height adjustment of the printing surface of the replacement mark 70 can be easily and accurately performed within an appropriate adjustment range.

  As the groove depth of the adjustment groove 87 increases, the upward movement amount when the adjustment cylinder 85 gets over the reference rib 81 in opposition to the urging force of the spring 86 increases, and the operation resistance increases correspondingly. It becomes difficult to operate. In such a case, if the adjustment cylinder 85 is rotated while the fastening screw 89 of the replacement mark 70 is loosened and the urging force of the spring 86 is reduced, the adjustment cylinder 85 can be easily rotated. After the adjustment cylinder 85 is rotated, the fastening screw 89 is screwed again to fix the name printing body 71 to the fastening screw 89.

  According to the date stamp in which the replacement mark 70 is directly attached to the upper surface of the fixed print body 3 as described above, the holder 72 is placed in the free space on the outer surface of the main case 7 by removing the fixed print body 3 from the main case 7. Since the replacement mark 70 can be attached to and detached from the fixed print body 3 in an exposed state, the replacement mark 70 can be easily replaced with less effort. Further, the height of the printing surface of the replacement mark 70 relative to the fixed printing body 3 can be directly adjusted by simply rotating the adjustment cylinder 85. Therefore, the height of the printing surface of the replacement mark 70 can be adjusted with less labor. Can be done accurately. Furthermore, since it is possible to confirm the stamped state by performing trial stamping without the need to re-attach the fixed printing body 3 to the main case 7, the series of labor required for adjusting the height of the printing surface of the replacement stamp 70 is reduced as a whole. Thus, the height adjustment operation can be easily performed.

  The replacement mark 70 attached to the fixed print body 3 is fixed to the fixed print body 3 through four engagement legs 79, and the right and left sides of the holder 72 are supported by positioning grooves 90. Further, the adjustment cylinder 85 receives the urging force of the spring 86, and the adjustment groove 87 is pressed against the reference rib 81. For this reason, even when a stamping reaction force acts on the name printing body 71, the engagement state between the adjustment groove 87 and the reference rib 81 is not released. This eliminates blurring or fading of the print characters, and can always print properly.

  As for the date stamp, the person in charge of management stores the key 36 in a predetermined place, and manages the usage status of the date stamp. At the start of work, after removing the upper cap 17, the key 36 is inserted into the keyhole 42 to unlock the lock unit 32, the cover cylinder 8 is opened, and the adjustment dial 22 faces the adjustment window 9. In this state, the adjustment dial 22 corresponding to the print belt 24 for printing the date and number is operated to select the character block suitable for the date to be used. When the date adjustment is completed, the lock unit 32 is locked in a state where the cover cylinder 8 is in the closed position, the opening movement of the cover cylinder 8 is prevented, and the person in charge of stamping with the upper cap 17 attached to the fastening boss 16 Pass the date stamp to. A series of date changing operations may be performed by the manager in charge, or may be performed by the person in charge of stamping in a situation where the manager in charge is present.

  According to the date stamp with a built-in case configured as described above, the cover cylinder 8 cannot be opened unless the lock unit 32 is unlocked with the regular key 36, so that it is a print belt type date stamp. Therefore, it is possible to surely prevent a user who is not the person in charge of management from changing the date. In addition, since the date can be changed simply by feeding the print belt 24, the date can be changed more easily and with less labor compared to the conventional replacement seal. Furthermore, since the person in charge of management only needs to manage the key 36, it is possible to greatly save the management effort compared to the replacement stamp that required to manage the replacement frame. There is no risk of losing or damaging the print element.

  In the state where the cover cylinder 8 is in the closed position, the outer surface of the mounting claw 30 of the stamp face holder 26 is covered with the cover cylinder 8 (see FIG. 12). For this reason, it is not possible to remove the fixed print body 3 from the main case 7 by disengaging the attachment claw 30. Accordingly, it is possible to prevent the date from being illegally changed by directly rotating the print belt 24 from the exit / exit port 12 side with the fixed print body 3 removed from the main case 7. Incidentally, when the fixing claw 30 can be removed from the main case 7 by disengaging the attachment claw 30, the exit / exit 12 having an opening area larger than the date window 28 is exposed, and therefore the print belt 24 is removed. It is possible to change the date by directly rotating.

  According to the date stamp described above, since the lock unit 32 is composed of a cylinder lock, the entire weight of the date stamp increases by the amount corresponding to the cylinder lock. Therefore, it is possible to appeal to the user that the date stamp has a higher security function than the conventional date stamp, as the impression when holding the date stamp with one hand is rich.

  When the date stamping frequency of the above configuration is high, the date stamp can be accommodated in a stand shown in FIG. The stand is an upper stand body 95 provided with a storage cylinder 94 for putting the date stamp in and out, a lower stand base 96 that supports the stand body 95, and a stand that is positioned directly below the storage cylinder 94. A mat holder 97 provided on the base 96 is used. The mat holder 97 is formed in a dish shape, and the ink storage mat 98 is accommodated therein. The date stamp in the non-use state is housed inside the housing cylinder 94 and is held in an upright position. Further, the printing surface of the fixed printing body 3 and the replacement stamp 70 contacts the upper surface of the ink storage mat 98. doing. Accordingly, the date stamp can be continuously stamped simply by taking it out of the storage cylinder 94, and the stamp cap 4 can be omitted in such a usage form.

  The name printing body 71 may print the number of times a competition or event is held in addition to printing the name or employee number of the stamper. In addition, a second date related to the reference date printed on the print belt 24, such as the time when the food is sold in the morning or afternoon, or the expiration date of the food, may be printed.

The frame 102 and the stamp base 103 are connected to each other via a connecting shaft 115 penetrating the frame 102 and can be slid up and down along the slide groove 116 provided in the frame 20 of the printing unit 2 and the frame 102 of the main body case 1. Further, in a state where the stamp surface 103 is slid to the lower end of the slide groove 116, the fixed printing body 3 and the stamp surface 103 can be swung around the connecting shaft 115 and operated in a posture separated from the frame 102.

  As described above, in the date stamp of the third embodiment, the posture can be changed between the assembly posture in which the stamp base 103 is attached to the lower end of the frame 102 and the separation posture in which the stamp base 103 is detached from the frame 102. The replacement mark 70 is exchanged in a state where the stamp stand 103 is in the separation posture. In a state where the stamping table 103 is moved down along the slide groove 116 to the separation posture, a large gap is formed between the stamping table 103 and the frame 102, and the holder 72 is exposed to the free space on the outer surface of the frame 102. Therefore, the replacement mark 70 can be exchanged in that state. Further, the replacement mark 70 is exchanged in a state where the stamp table 103 is moved downward along the slide groove 116 and the stamp table 103 is swung around the connecting shaft 115 and positioned on the front side of the frame 102. You may go. The replacement mark 70 in the use state is accommodated in the frame 102 of the main body case 1.

  In the first embodiment, the height adjustment mechanism for the replacement mark 70 is provided between the holder 72 and the fastening screw 89, but this is not necessary, and the height adjustment mechanism is a function between the name printing body 71 and the fastening screw 89. It can be provided in between. For example, as shown in FIG. 22, the screw boss 120 is provided on the upper surface of the printing stand 73 of the name printing body 71, and the female screw 121 is formed on the inner surface thereof. The screw boss 120 is supported by a guide hole 122 provided in the center of the base wall 78 of the holder 72, whereby the entire name printing body 71 is guided freely by the holder 72 only in the up and down direction. The fastening screw 89 also serves as a height adjuster, and includes a screw shaft 123 that is screwed into the female screw 121, a cylindrical portion 124 that is received on the upper surface of the base wall 78, and an adjustment knob 125 that is provided above the cylindrical portion 124. Is integrated. Between the base wall 78 and the printing stand 73, a friction applying spring (spring) 126 for preventing the screw shaft 123 from loosening is disposed.

  In the height adjustment mechanism of FIG. 22, when the adjustment knob 125 of the fastening screw 89 is screwed in, the entire name printing body 71 is drawn toward the base wall 78, and conversely when the adjustment knob 125 is loosened, the name printing body. The entire 71 moves in a direction away from the base wall 78. Therefore, the height of the printing surface of the name printing body 71 can be freely adjusted by simply rotating the adjustment knob 125. Note that the height adjustment mechanism of Example 1 can adjust the height of the print surface stepwise, whereas the height adjustment mechanism of FIG. 22 adjusts the height of the print surface steplessly. It is different in that it can be done. As can be understood from this embodiment, the height adjustment mechanism of the replacement mark 70 can be configured using male and female screws as adjustment elements, and a structure other than the configuration described in FIG. 22 can be employed.

  In addition to the above embodiment, the number of adjustment grooves 87 formed can be set to a necessary number according to the difference in the sizes of date stamps and replacement marks 70. The shapes of the reference rib 81 and the adjustment groove 87 do not need to be triangular or inverted V-shaped, and can be formed in other shapes such as a corrugated shape or a saw blade shape as long as they can be engaged with each other. It is sufficient if at least one reference rib 81 is provided. The spring 86 can be configured by a leaf spring, a kick spring, a rubber block, or the like. The replacement mark 70 can be composed of a plurality of printing bodies, and if necessary, the replacement marks 70 can be arranged at two places before and after the fixed printing body 3 with the printing belt 24 interposed therebetween. The fixed printed body 3 can be formed in an oval shape or a quadrilateral shape in addition to a circular shape. The date stamp preferably has a lock structure, but may be a date stamp without a lock structure. The upper cap 17 does not need to be attached to and detached from the fastening boss 16 and can be attached to and detached from the cover cylinder 8 provided with the engagement structure.
