Description

  The present invention relates to a dial exposure type date stamp in which an adjustment dial for rotating a printing belt is always exposed outside a main body. The date stamp according to the present invention is used as, for example, a receipt stamp or a reception stamp, and has a lock structure that prevents the stamp date from being changed unnecessarily.

  A date stamp provided with this type of lock structure has been previously proposed by the present applicant (Patent Document 1). In this case, a main body case is constituted by a main case that accommodates the printing unit and a round cylindrical cover cylinder that covers the outer surface of the main case, and the outer surface of the main case is covered with the cover cylinder for printing. To change the date, slide the cover cylinder to the open position above the main case and rotate the print belt with the adjustment dial while the print surface at the lower end of the print belt is detached from the print window on the stamp stand. Manipulate. In order for the manager in charge to supervise such a date change operation, a lock structure is provided between the cover cylinder and the main case to prevent the cover cylinder from being opened. The lock structure consists of a cylinder lock that is mounted horizontally on the cover cylinder, a lock body that is engaged and disengaged with the cylinder lock, and a lock piece that is provided on the side of the main case corresponding to the lock body. Thus, the sliding operation of the cover cylinder to the open position in the locked state can be restricted.

  According to the date stamp of Patent Document 1, the cover cylinder can be slid to the open position by unlocking the cylinder lock and releasing the engagement state between the locking body and the lock piece. Therefore, by keeping the key of the cylinder lock by the person in charge of management, it is possible to prevent the date from being intentionally changed due to an unauthorized operation of the adjustment dial, and to improve the security of the date stamp. In addition, since the person in charge of management only has to manage the key for the cylinder lock, the labor of management can be greatly simplified.

  Performing the date changing operation as described above under the supervision of the manager in charge has been widely performed in the past for replacement stamp type date stamps. For example, the replacement stamp type date stamp of Patent Document 2 has two types that can be replaced inside the stamp by providing a stamp portion at the bottom of the date stamp body and fixing a master stamp on the bottom surface of the stamp of the stamp portion. The stick mark is accommodated. The master stamp is provided with a fixed printing unit that prints, for example, a company name, bank name, or administrative institution name. One of the stick marks is a combination stamp type printing unit configured by connecting a plurality of element stamps. By changing the combination of element stamps, the stamp date such as year, month, day, etc. can be changed. Can be changed. Another stick mark consists of an auxiliary printing body that prints the name of the stamper or employee number, for example, and changes the name of the stamper printed by changing the stick mark whenever the stamper changes. be able to. Such printing content change operation is performed with the presence of the supervisor. However, since it takes a lot of time to replace the stick mark, the effort required to change the print content is not the ratio of the date stamp of Patent Document 1.

  The date stamp of Patent Document 1 is configured as a dial storage type date stamp, in which the peripheral surface of the adjustment dial at the time of stamping is covered with a cover cylinder. On the other hand, in the date stamp according to the present invention, the operation peripheral surface of the adjustment dial for rotating the print belt is always exposed to the outer surface of the main body, and such a dial exposure type date stamp is disclosed in, for example, Patent Literature 3 is widely known as seen in the rotating rubber stamp. There, the main body is composed of a cover body made of press-molded products and a fixed frame that is externally fitted to the upper surface of the cover body, and printing is performed with the front cover and rear cover of the cover body divided into front and rear. The operation peripheral surface of the adjustment dial is exposed on the front and rear of the main body by sandwiching the unit back and forth.

  In the dial storage type date stamp, a stamp stand with a master stamp is fixed to the lower end of the main case, and the printing unit is pushed up with a spring to accompany the cover cylinder sliding to the open position. Then, the printing surface of the printing belt is detached from the printing window of the printing stand, and the adjustment dial is rotated in this state. On the other hand, in the case of dial-exposed date stamps, the printing stand on the lower end of the main body is slid downward to disengage the printing window on the printing stand from the printing surface of the print belt. Rotate the. As described above, the dial storing type date stamp and the dial exposure type date stamp have a great difference in the method of separating the printing surface of the printing belt from the stamp base. In addition, the dial-exposed date stamp is greatly different from the dial storage-type date stamp in that the useless structure is cut off and the whole is simple and compact.

JP 2011-25440 A (paragraph number 0050, FIG. 12) Japanese Patent No. 3688769 (paragraph numbers 0006 to 0007, FIG. 1) JP2009-133201A (paragraph numbers 0024 to 0026, FIG. 2)

  It is desired to improve the security of the date stamp by adding a lock structure to the dial-exposed date stamp as well as the dial storing date stamp. However, the dial-exposed date stamp is significantly different from the dial-accommodating date stamp in that the printing surface and the stamp stand are separated, and there is no structure equivalent to the dial-accommodating date stamp cover tube. It is extremely difficult to apply the lock structure of Patent Document 1 to dial-exposed date stamps.

  In the dial-exposed date stamp, the front cover and the rear cover constituting the main body face the vicinity of the rotation locus of the print belt, so there is no excess space around the adjustment dial. For this reason, it is difficult to secure a space for incorporating the lock structure inside the main body in the dial-exposed date stamp with a simple overall structure. Furthermore, in order to lock the slide base that slides up and down so that it cannot be opened, it is necessary to provide a lock structure on the side of the main unit, but as described above, the basic structure of the dial-exposed date stamp is followed. It is extremely difficult to provide a lock structure. The fact that there is no commercially available cylinder lock that is small enough to be placed using a smaller space is also a major barrier.

As a result of studying the date stamp and the lock structure with the aim of adding a locking function to the dial-exposed date stamp, the present inventor found a solution and found this solution. It came to propose invention.
It is an object of the present invention to provide a lock structure that restricts the opening operation of the stamp stand, and prevents the adjustment dial from being illegally operated to intentionally change the date. An object of the present invention is to provide a dial exposure type date stamp that can improve security.
An object of the present invention is to provide a dial exposure type date stamp which can add a lock structure while following the basic structure of the dial exposure type date stamp, and thus can reduce the cost by suppressing the overall cost of the date stamp. It is to provide.

  The date stamp according to the present invention is a dial exposure type date stamp, and a printing unit 6 including a plurality of printing belts 34 and an adjustment dial 32 is accommodated in the main body 1. The operation peripheral surface 40 of the adjustment dial 32 is always exposed outside the main body 1. Furthermore, when adjusting the marking surface of the print belt 34, the dial exposure type date stamp that switches the stamp table 4 in the direction away from the main body 1 and switches from the printing posture to the printing surface adjustment posture is applied. The main body 1 is provided with a lock structure that prevents the stamp stand 4 from being displaced to the stamp adjustment posture. The lock structure is fixed to the upper part of the main body 1, and a key lock 72 that can be locked or unlocked by a key 86, an interlocking body locking device 73 that can be switched between a locked posture and an unlocked posture by the key lock 72, and the stamp base 4 And an interlocking body 20 that is displaced in conjunction with the posture changing operation. The interlocking body 20 is disposed on the peripheral wall of the main body 1 that faces the shaft end of the dial shaft 31 of the adjustment dial 32. In a state in which the stamp base 4 is in the stamping posture and the interlocking body locking device 73 is in the locking posture, the interlocking body locking device 73 is engaged with the interlocking body 20 to prevent the stamping surface base 4 from being displaced to the stamping surface adjustment posture. It is characterized by that.

  An adjustment body 37 that adjusts the height of the printing surface of the printing belt 34 is arranged on the upper part of the printing unit 6. The key lock 72 and the interlocking body locking tool 73 are arranged in the main body 1 above the adjustment body 37, and as shown in FIG. It is located on the vertical center axis P.

  The interlocking body 20 is composed of a plate-like body that is guided and supported by the peripheral wall of the main body 1 so as to be slidable up and down. The interlocking body 20 is connected to the stamp table 4 so as to be able to move together.

  The operation peripheral surface 40 of the adjustment dial 32 is exposed to the outside of the main body 1 from at least one of the front and rear walls of the cover main body 18 constituting the main body 1. A pair of left and right interlocking bodies 20 are arranged along the left and right walls of the cover body 18 parallel to the rotation plane of the adjustment dial 32.

  An interlocking body guide structure is provided between the main body 1 and the interlocking body 20 to guide and support the interlocking body 20 so as to be slidable up and down. The interlocking body guide structure includes a guide body 27 provided on the outer surface of the main body 1 and a slide protrusion 88 formed on the inner surface of the interlocking body 20 and slidably guided by the guide body 27.

  The cover main body 18 constituting the main body 1 is composed of a front cover 18a and a rear cover 18b made of a plastic molded product divided into front and rear. The front cover 18a and the rear cover 18b are joined and integrated so as to cover the printing unit 6 from the front and the back. A guide body 27 is projected from a joint portion between the front cover 18a and the rear cover 18b, and a slide projection 88 is formed on the inner surface of the interlocking body 20.

  The key lock is a cylinder lock 72. The interlocking body locking tool includes a cover lock body 73 having a lock wall 81 and an unlock groove 82. In a state where the cover lock body 73 is switched to the locked position by the cylinder lock 72, the lock wall 81 is engaged with the lock claw 89 provided on the interlocking body 20, and the interlocking body 20 is prevented from being displaced to the stamping face adjustment attitude. To do. In a state where the cover lock body 73 is switched to the unlocked posture by the cylinder lock 72, the unlock groove 82 is made to face the lock claw 89 of the interlocking body 20. The lock wall 81 in this state is located outside the movement locus of the lock claw 89.

  A printing surface for the master mark 5, a printing surface for the belt-type printing unit 6, and a printing surface for the auxiliary printing body 7 are arranged on the stamp surface 4. The auxiliary printing body 7 is disposed in the accommodating space 42 provided between the transition locus of the print belt 34 and the case structure that directly faces the transition locus.

  As shown in FIG. 16, the auxiliary print body is constituted by a replacement mark 7 that is attached to and detached from the stamp base 4 from the rear side of the main body 1. The operation peripheral surface 40 of the adjustment dial 32 is exposed outside the front and rear walls of the cover body 18.

  The auxiliary printing body 7 includes a printing surface portion 45 including a plurality of printing bodies 48 and an operation unit 46 that is disposed in a state where at least a part is exposed to the outside of the main body unit 1. The printing surface of the marking surface 45 is changed by rotating the marking surface 45 with the operation unit 46.

  In the present invention, in the dial exposure type date stamp, the key lock 72 fixed to the upper part of the main body 1, the interlocking body locking device 73 that is switched by the key lock 72, and the posture changing operation of the stamp base 4. The lock structure is composed of the interlocking body 20 that is displaced in conjunction with the interlocking body. Further, in a state where the interlocking body 20 is disposed on the peripheral wall of the main body portion 1 facing the shaft end of the dial shaft 31 of the adjustment dial 32, the stamp base 4 is in the stamping posture, and the interlocking body locking device 73 is in the locking posture. The interlocking body locking tool 73 is engaged with the interlocking body 20 so that the stamp base 4 can be prevented from being displaced from the stamping posture to the stamping surface adjusting posture.

  As described above, according to the dial exposure type date stamp provided with the lock structure, it is possible to reliably prevent the adjustment dial 32 from being illegally operated by the stamper and intentionally changing the stamp date. Like the dial storage type date stamp, the reliability and security of the stamping result can be improved. Further, since the person in charge of management only has to manage only the key 86 for the lock 72, it is possible to greatly simplify the trouble of managing the dial exposure type date stamp. Further, since the interlocking body locking device 73 and the interlocking body 20 are engaged with each other at the upper part of the cover body 18 to prevent the change of the posture of the stamp base 4, the structure corresponding to the dial storage type date stamp cover cylinder Despite the absence of the lock, the dial structure can be added to the dial-exposed date stamp without any problem. By disposing the interlocking body 20 on the peripheral wall of the main body 1 facing the end of the dial shaft 31 of the adjustment dial 32, the interlocking body 20 can be assembled to the main body 1 without being disturbed by the adjustment dial 32. Therefore, the structure of the interlocking body 20 can be simplified and the labor required for the assembly can be reduced.

  The key lock 72 and the interlocking body locking tool 73 are disposed on the main body 1 above the adjustment body 37, and the longitudinal center axis Q of the keylock 72 and the interlocking body locking tool 73 is placed on the longitudinal center axis P of the printing unit 6. According to the date stamp to be positioned, the key lock 72 and the interlocking body locking tool 73 can be assembled to the main body 1 using the space above the adjustment body 37. Therefore, for example, the arrangement structure of the key lock 72 and the interlocking body locking tool 73 with respect to the main body 1 is not limited as compared with the case where the key lock 72 and the interlocking body locking tool 73 are disposed inside the printing unit 6, and This simplifies the structure and reduces the labor required for assembly. Furthermore, since the lock structure can be added by following the basic structure of the date dial of the conventional dial exposure type, it is possible to minimize the structural change of the date stamp, and thus the dial exposure with the lock structure. The overall cost of the date stamp of the mold can be suppressed and the cost can be reduced.

  When the interlocking body 20 is constituted by a plate-like body and the interlocking body 20 is connected to the stamp table 4 so as to be able to move together, the outer surface of the peripheral wall of the main body 1 is covered with the interlocking body 20 and the dial exposure having a lock structure is provided. The appearance of the date stamp on the mold can be simplified. Further, since the interlocking body 20 is configured as an independent part and is connected to the stamp table 4 so as to be able to move together, the interlocking body 20 can be manufactured at a low cost by a molding die having a simpler structure. Therefore, the cost increase associated with the addition of the lock structure can be reduced.

  If a pair of left and right interlocking bodies 20 are arranged along the left and right walls of the cover main body 18 parallel to the rotation plane of the adjustment dial 32, each interlocking body 20 can be slidably guided by the left and right walls of the cover main body 18. Further, since the stamp stand 4 that is displaced between the stamping posture and the stamp adjustment posture is supported by the pair of left and right interlocking bodies 20 that accompany the stamp stand 4, the posture change of the stamp stand 4 can be performed smoothly and reliably. Can improve the usability of date stamps.

  When the guide body 27 provided on the outer surface of the main body 1 and the slide protrusion 88 formed on the inner surface of the interlock body 20 constitute an interlock body guide structure, and the slide protrusion 88 is slid and guided by the guide body 27, the interlock body 20 is moved. It can be slid up and down in a more stable state. Therefore, when the interlocking body 20 accompanies the stamp stand 4 and slides up and down, the interlocking body 20 is prevented from tilting or the interlocking body 20 meandering and the like, and the posture of the stamp stand 4 is prevented. Changes can be made more smoothly and accurately.

  When the cover body 18 is composed of a front cover 18a and a rear cover 18b, a guide body 27 is projected using the joints of the front and rear covers 18a and 18b, and a slide protrusion 88 is formed on the inner surface of the interlocking body 20. The useless movement of the interlocking body 20 can be regulated while realizing the simplification of the interlocking body guide structure. Moreover, since the slide protrusion 88 provided on the inner surface of the interlocking body 20 also functions as a reinforcing structure of the interlocking body 20, there is an advantage that the interlocking body 20 that has received a drop impact can be prevented from being damaged.

  According to the cover lock body 73 provided with the lock wall 81 and the unlock groove 82, the stamp stand 4 can be placed in a printing posture by a simple operation by simply switching the cover lock body 73 between the locked position and the unlocked position with the cylinder lock 72. Can be reliably prevented from being manipulated to the printing face adjustment posture. In addition, since the overall weight of the date stamp is increased by configuring the lock structure using the cylinder lock 72, 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. Furthermore, by configuring the lock structure using a commercially available cylinder lock 72, the overall cost of the date stamp provided with the lock structure can be reduced.

  When the auxiliary printing body 7 is arranged in the accommodating space 42 provided between the transition locus of the printing belt 34 and the case structure facing the transition locus, printing by the auxiliary printing body 7 is performed in addition to the printing by the printing unit 6. Can be displayed simultaneously. Further, in the dial exposure type date stamp, the stamp face of the auxiliary printing body 7 is intentionally changed by utilizing the fact that the stamp face 4 is changed to the stamp face adjustment posture and the printing face of the printing unit 6 is changed. At the same time. Accordingly, it is possible to improve the reliability and security of the stamping result of the date stamp provided with the auxiliary printing body 7 in which the printing information is diversified.

  If the auxiliary printing body is composed of the replacement mark 7 that is attached to and detached from the stamp table 4, the replacement mark 7 can be replaced when the printing surface of the printing unit 6 is changed. Various information such as name, employee number, department name, store name, food cooking time, and expiration date can be printed with the replacement mark 7. Further, in the date stamp provided with the replacement mark 7, if the operation peripheral surface 40 of the adjustment dial 32 is exposed outside the front and rear walls of the cover body 18, adjustment is performed with the fingertip pinching the front and rear of the dial peripheral surface. The dial 32 can be accurately rotated. Therefore, the feeding operation and the position adjusting operation of the print belt 34 by the adjustment dial 32 can be performed more simply and accurately.

  According to the auxiliary printing body 7 having the marking surface portion 45 having the plurality of printing bodies 48 and the operation portion 46 at least a part of which is exposed to the outside of the main body 1, the operation portion 46 is simply rotated. The print surface of the stamp surface 45 can be changed. Therefore, compared with the date stamp in which the auxiliary printing body is constituted by the replacement mark, the printing content of the auxiliary printing body 7 can be changed easily and with less effort. Further, it is not necessary to store and manage the auxiliary printing body 7 that is not in use. Therefore, the loss of the auxiliary printing body 7 when not in use can be eliminated, and the usability of the date stamp can be improved.

The auxiliary printing body 7 is assembled with the marking surface 45 and the operation portion 46 in close contact with the inside and outside of the holder end wall 55, and is integrated with the holder 19 by screwing a nut 61 into the screw shaft portion of the connecting shaft 50. It is. In this assembled state, the print content of the print body 48 located on the lower surface side of the support 47 and the display content of the print display 51 located on the upper surface of the operation knob 49 are the same. Even when the operation unit 46 is rotated, the printed content of the printing body 48 matches the displayed content of the printed display 51. Accordingly, the user can clearly know the name of the stamper printed by the auxiliary printing body 7 only by confirming the display content of the print display 51.

  As shown in FIG. 1, the holder 19 receives the left and right slide walls 54 with the left and right walls of the belt frame 30 including the peripheral wall of the guide window 35, and the lower end of the slide wall 54 with the inner bottom wall of the stamp base 4. By receiving it, it is guided and supported so that it can slide forward and backward. Further, by engaging the left and right ends of the movable frame 64 assembled to the guide window 35 with the slide window 56 opened in the slide wall 54, the holder 19 is slid back and forth between the left and right walls of the belt frame 30 and the movable frame 64. Supports freely.

  In the holder 19 assembled to the belt frame 30, the printing surface portion 45 of the auxiliary printing body 7 is adjacent to the printing unit 6 (the state shown in FIG. 6), and the printing surface portion 45 is moved rearward from the printing unit 6. It can be slid back and forth between the adjustment position (state shown in FIG. 14). The restricting ribs 58 of the holder 19 at the printing position are received by the upper half of the left and right side edges of the holder opening 12 of the stamp base 4, and the step 60 is the left and right side edges of the lower half of the holder opening 12. 59 is engaged. Accordingly, the holder 19 cannot be pulled out from the holder opening 12 unless the stamp base 4 is displaced from the upper printing posture to the lower printing surface adjustment posture. The restricting rib 58 also serves as an operation knob when the holder 19 is put in and out of the stamp base 4.

  An auxiliary marking urging structure is provided on the upper side of the bridge 33 inside the circulation locus of the printing belt 34 to urge the auxiliary printing body 7 through the holder 19. As shown in FIGS. 1, 3, 6, and 7, the auxiliary stamping biasing structure includes a movable frame 64 that is supported by a guide window 35 provided in the belt frame 30 so as to be slidable up and down, and an upper side of the movable frame 64. The fixed frame 65 is disposed and supported by the upper portion of the guide window 35, and the auxiliary stamp spring 66 is disposed between the frames 64 and 65 to move and urge the movable frame 64 downward.

  In FIG. 3, the movable frame 64 is formed of a U-shaped frame that opens upward, and leg pieces 67 that engage with the lower peripheral wall of the guide window 35 protrude downward on the lower surfaces of the left and right ends. . Further, four guide walls 68 for guiding the fixed frame 65 so as to be slidable relative to each other are projected upward on the inner surface of the movable frame 64. The fixed frame 65 is formed of an I-shaped rod body that is long on the left and right, and a spring seat 69 for the auxiliary stamp spring 66 is formed in a concave shape on the lower surface side at the center of the left and right. In a state where the movable frame 64, the fixed frame 65, and the auxiliary stamp spring 66 are assembled, the movable frame 64 and the fixed frame 65 are operated close to each other while resisting the biasing force of the auxiliary stamp spring 66, and in this state, the movable frame 64 and the fixed frame spring are fixed. By inserting the frame 65 through the left and right guide windows 35, the auxiliary stamp urging structure can be integrated with the belt frame 30. Further, the holder 19 is integrated with the belt frame 30 by engaging the slide window 56 with both side ends of the movable frame 64 while expanding the slide wall 54 of the holder 19 to which the auxiliary printing body 7 is assembled. it can. The stamp stand 4 is assembled to the holder 19 in this state from below.

  As described above, in the free state in which the cover main body 18 and the holder 19 are assembled to the printing unit 6 and the stamp base 4 is assembled to the holder 19, the printing surface of the master mark 5 and the printing unit 6 are shown in FIG. The printing surface is located on the same plane. However, the printing surface of the auxiliary printing body 7 in the free state is slightly protruded downward from the printing surface of the master mark 5. This is to prevent the peripheral structure of the auxiliary printing body 7 from being unnecessarily complicated and complicating the assembly when the height adjusting structure is added to the auxiliary printing body 7. This is to prevent the printed characters from fading by making the printing surface protrude downward from the printing surface of the master mark 5. Incidentally, the printing unit 6 can adjust the height of the printing surface by rotating the adjustment ring 37 as necessary, and can match the printing surface position of the master mark 5.

  In order to prevent the printing contents of the printing unit 6 and the printing contents of the auxiliary printing body 7 from being intentionally changed by the stamper, the stamp base 4 is displaced from the stamping posture to the stamping adjustment posture on the main body 1. The lock structure which prevents this is provided. In FIG. 9, the lock structure includes a cylinder lock (key lock) 72 fixed to the upper part of the cover main body 18, a cover lock body (interlocking body lock tool) 73 that can be switched between a locked posture and an unlocked posture by the cylinder lock 72, It comprises a side cover (interlocking body) 20 that accompanies the posture changing operation of the stamp stand 4.

  The cylinder lock 72 is a commercially available product, and a lock receiving seat 77 of the cover body 18 is sandwiched up and down by a flange wall 75 provided on the upper surface of the cylinder lock 72 and a nut 76 screwed into the screw shaft of the lock body. (See FIG. 6). As shown in FIG. 9, the cover lock body 73 is integrally provided with a connecting wall 80 at the center of the upper and lower sides and a pair of partial arc-shaped locking walls 81 around the connecting wall 80, and the longitudinal section is H-shaped. It is made of a plastic molded product, and an unlock groove 82 that allows the side cover 20 to move downward is cut out between the lock walls 81. An oblong connection hole 83 is formed in the center of the connection wall 80. By engaging the output shaft 84 of the cylinder lock 72 in this connection hole 83 and screwing the nut 85 into the screw shaft of the output shaft 84. The cover lock body 73 is integrated with the previous output shaft 84 so as to be rotatable together. By rotating the key 86 inserted into the keyhole, the cylinder lock 72 can be locked or unlocked. At the same time, the cover lock body 73 fixed to the output shaft 84 is changed into a locked posture and an unlocked posture. Can be switched.

  As described above, the cylinder lock 72 and the cover lock body 73 are disposed in the main body 1 above the adjustment ring 37 for adjusting the marking face height, and the longitudinal center axis Q of the cylinder lock 72 and the interlocking body lock tool 73 is The cover unit 18 is assembled to the cover body 18 in a state of being located on the longitudinal center axis P of the printing unit 6 (see FIG. 9). As described above, when the cylinder lock 72 and the cover lock body 73 are disposed above the adjustment ring 37, the cylinder lock 72 and the cover lock body 73 are compared with the case where the cylinder lock 72 and the cover lock body 73 are disposed inside the printing unit 6. The attachment structure of the body 73 to the cover main body 18 can be simplified, and the labor required for assembly can be reduced. Further, since the cylinder lock 72 and the cover lock body 73 can be arranged in the space above the adjustment ring 37, the lock structure can be added by following the basic structure of the dial-exposed date stamp as it is. The overall cost of the date stamp provided can be suppressed and the cost can be reduced. Even a relatively large commercially available cylinder lock 72 can be assembled without any problem, and there is an advantage that the degree of freedom in design is high.

  3 and 9, the side cover 20 is formed of a vertically long plate-like plastic molded product having a ridge structure, and a pair of slide ribs (slide protrusions) 88 are formed at the front and rear centers of the inner surface. A pair of lock claws 89 are projected in succession. The guide rib 27 described above engages with a groove defined by the pair of slide ribs 88 to guide the side cover 20 so as to be slidable up and down. In this embodiment, the guide rib 27 and the slide rib 88 constitute an interlocking body guide structure.

  A connecting claw 90 that engages with the engaging rib 15 of the stamp base 4 protrudes downward from the lower portion of the side cover 20. The pair of side covers 20 are attached to the left and right walls of the cover body 18 parallel to the rotation plane of the adjustment dial 32 with the guide ribs 27 engaged with the grooves between the slide ribs 88, It is guided and supported by the same wall so that it can slide up and down. In a state where the side cover 20 is attached to the cover main body 18, the pair of lock claws 89 enter the inside of the cover main body 18 from the lock window 26, and the claws of the lock claw 89 are engaged with the inner edge of the lock window 26. The connecting claw 90 enters the left and right sides of the stamp base 4 and engages with the engaging rib 15. As a result, the side cover 20 and the stamp base 4 are connected and integrated (see FIG. 1), so that the side cover 20 moves vertically along the left and right walls of the cover body 18 along with the vertical movement of the stamp base 4. Can slide. As described above, by arranging the side cover 20 on the peripheral wall of the main body 1 facing the end of the dial shaft 31 of the adjustment dial 32, the side cover 20 is not obstructed by the adjustment dial 32 or the adjustment ring 37. 20 can be assembled to the cover body 18 without hindrance, so that the structure of the side cover 20 can be simplified and the labor required for the assembly can be reduced.

  In a state in which the stamp base 4 is in the stamping position and the cover lock body 73 is switched to the locked position by the cylinder lock 72, the lock claw 89 of the side cover 20 has the upper end surface of the lock wall 81 as shown in FIGS. Is engaged. Therefore, the stamp base 4 connected to the side cover 20 is held in the upper printing posture. Accordingly, unless the cylinder lock 72 is unlocked with the key 86, the stamp base 4 cannot be displaced to the stamp face adjustment posture below the main body 1, and the print contents of the print unit 6 as well as the auxiliary print body 7 cannot be changed.

  When changing the printing contents of the printing unit 6 and the auxiliary printing body 7, the grip 3 is removed from the grip boss 21 of the cover body 18 to expose the upper surface of the cylinder lock 72 as shown in FIG. Next, by inserting the key 86 into the keyhole of the cylinder lock 72 and unlocking the cylinder lock 72, the cover lock body 73 is switched to the unlocked posture as shown in FIG. In this state, the cover lock body 73 rotates 90 degrees, the unlock groove 82 faces the lock claw 89 of the side cover 20, and the lock wall 81 is retracted outside the movement locus of the lock claw 89. Therefore, the side cover 20 can be moved downward together with the stamp base 4. Therefore, as shown in FIG. 11, the stamp stand 4 and the side cover 20 can be lowered to switch the stamp stand 4 to the stamp adjustment posture. Since the lock claw 89 in this state is received by the lower end portion of the lock window 26, the stamp base 4 does not move downward beyond the stamp face adjustment posture.

  In the state where the stamp stand 4 is displaced to the stamp adjustment posture, the print block at the lower end of the print unit 6 is relatively disengaged from the print window 13 of the stamp stand 4 as shown in FIG. You can change the date. Further, as shown in FIG. 10, the left and right side edges 59 of the holder opening 12 of the stamp table 4 are separated from the step portion 60, and the print body 48 on the lower surface of the auxiliary print body 7 is further connected to the auxiliary print window 14 of the stamp table 4. Therefore, the holder 19 can be pulled out from the printing position to the adjustment position.

  As shown in FIG. 14, since the auxiliary printing body 7 drawn out to the adjustment position does not have a case structure that contacts and interferes with the printing surface portion 45, the printed content can be simplified by simply rotating the operation portion 46. Can be changed. After that, the holder 19 is returned to the printing position, and the stamp base 4 is returned to the printing posture, whereby the side cover 20 moves along with the stamp base 4 and the lock claw 89 rises above the unlock groove 82. In this state, by operating the cylinder lock 72, the cover lock body 73 is switched to the locked state, the lock wall 81 and the lock claw 89 are engaged, and the print contents of the print unit 6 and the auxiliary print body 7 are changed. It can be regulated again.

  The series of operations related to the change of the print content is, for example, that the stamper reports to the manager of the key 86 that the print content needs to be changed, borrows the key 86 from the administrator, and Before the operation, the lock structure is unlocked to change the print contents. Further, the date stamp with the changed print content is stamped, and after the administrator confirms that the print content is appropriate, the key 86 is returned to the administrator. Alternatively, the manager of the key 86 performs a series of content change operations, and passes the date stamp on which the print content has been changed to the stamper.

  As described above, in the state in which the master mark 5, the printing unit 6, and the auxiliary printing body 7 are pressed against the surface of the printing paper, the auxiliary printing body 7 has a printing surface that is more than the printing surface of the master mark 5. The printing reaction force larger than the other printing surface is received by the amount protruding downward. However, since the holder 19 that supports the auxiliary print body 7 is pushed down and biased by the auxiliary stamping structure, as shown in FIG. 15, most of the preceding printing reaction force is generated between the auxiliary print body 7 and the holder 19. The movable frame 64 is absorbed by sliding toward the fixed frame 65 against the urging force of the auxiliary stamp spring 66. A state in which the holder 19 and the auxiliary printing body 7 are moved upward is indicated by an imaginary line.

  Thus, the upward movement operation of the auxiliary printing body 7 at the time of stamping is absorbed by the movement of the movable frame 64 toward the fixed frame 65. A part of the printing reaction force is absorbed by elastic deformation of the rubber print body 48. Therefore, the print characters printed by the printing body 48 are not crushed or deformed, and the same print quality as the print characters printed by the master mark 5 or the print unit 6 can be obtained. The date marks when not in use are stored in a standing posture on a stand 8 indicated by an imaginary line in FIG. 2, and each of the printing surface of the master mark 5, the printing surface of the printing unit 6, and the printing surface of the auxiliary printing body 7. Is closely attached to an ink mat provided on the inner bottom of the stand 8.

  According to the dial-exposed date stamp configured as described above, the marking surface of the print belt 34 and the marking surface of the auxiliary printing body 7 cannot be changed unless the cylinder lock 72 is unlocked with the key 86. Accordingly, it is possible to surely prevent the date or the like from being intentionally changed due to an unauthorized operation of the adjustment dial 32 by the person in charge of the stamp, and to improve the reliability and security of the stamp result. Further, since the person in charge of management only has to manage only the key 86 for the cylinder lock 72, the trouble of managing the dial exposure type date stamp can be greatly simplified. Further, since the cover lock body 73 and the side cover 20 are engaged with each other at the portion above the adjustment body 37 of the cover main body 18 to prevent the posture of the stamp table 4 from changing, it corresponds to a dial storage cover date stamp cover cylinder. In spite of the absence of the structure to be used, the lock structure can be added to the dial-exposed date stamp without any trouble.

  16 and 17 show another embodiment of the dial exposure type date stamp according to the present invention. In this case, the dial shaft 31 of the printing unit 6 is arranged in the front and rear center of the belt frame 30 so that the front and rear operation peripheral surfaces 40 of the adjustment dial 32 are exposed outside the front and rear walls of the cover body 18. Further, the auxiliary printing body disposed in the accommodation space 42 on the rear side of the printing unit 6 is constituted by the replacement mark 7. The replacement mark 7 is fixed to the support body 92, a knob 93 that is continuous with the rear surface of the support body 92, a latching piece 94 that protrudes from the left and right of the upper surface of the support body 92, and the lower surface of the support body 92. It is composed of a rubber printing body 95 or the like.

  The stamp base 4 is integrally provided with a square frame-shaped slide frame 10 and a circular seat wall 11, and is inserted through the left and right walls of the slide frame 10, the left and right walls of the cover body 18, and the left and right walls of the belt frame 30 simultaneously. It connects with the cover main body 18 via the bolt 96 to do. Reference numeral 97 denotes a nut screwed into the bolt 96. Since the left and right walls of the cover body 18 and the left and right walls of the belt frame 30 are formed with long slide grooves 98 extending vertically through which the bolts 96 are inserted, the stamp base 4 has an upper printing posture with respect to the cover body 18. It is possible to slide up and down between the lower printing face adjustment posture. Side covers (interlocking bodies) 20 disposed on the left and right walls of the cover body 18 are connected to the left and right walls of the slide frame 10 using the bolts 96 (see FIG. 17).

  The replacement mark 7 can be attached / detached to / from the stamp base 4 from the attachment / detachment opening 100 opened at the lower rear surface of the cover body 18. An adjustment screw 101 is screwed onto the upper surface of the support body 92. By adjusting the screwing amount of the adjustment screw 101, the printing surface height of the printing body 95 can be adjusted. The operating head of the adjustment screw 101 is received by a stopper 102 that protrudes inward from the upper edge of the attachment / detachment port 100. The cover body 18 is composed of a front cover 18a and a rear cover 18b each made of a plastic molded product, similar to the date stamp described in FIGS. 1 to 15, and the print unit 6 is moved forward and backward by both covers 18a and 18b. Hold between.

  According to the dial exposure type date stamp described above, a lock structure is added to the date stamp that has been widely used in the past, so that the print content of the print unit 6 is prevented from being intentionally changed by the stamper. Therefore, it is possible to improve the reliability and security of the contents printed by the date stamp. Further, the basic structure of the dial exposure type date stamp according to this embodiment is the same structure as the date stamp of Patent Document 3, and the lock is maintained while following the basic structure of the conventional dial exposure type date stamp. Since a structure can be added, the overall cost of the date stamp can be suppressed and the cost can be reduced. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members and the description thereof is omitted. The same applies to the embodiments described below. As can be understood from the embodiments described with reference to FIGS. 16 and 17, the auxiliary printing body can be constituted by the replacement mark 7, and the employee number of the stamper can be obtained by replacing the replacement mark 7 as necessary. , Department name, store name, etc. can be changed.

  FIG. 18 shows still another embodiment of the dial exposure type date stamp according to the present invention. The structure of the date stamp according to this embodiment is basically the same as the structure of the date stamp described with reference to FIGS. 1 to 15, but the operation recess 105 is formed in the rear cover 18 b so that the rear side of the adjustment dial 32. The operation peripheral surface 40 is also exposed to the outside of the main body 1. As described above, when the operation peripheral surface 40 before and after the adjustment dial 32 is exposed to the outside of the main body 1, the adjustment dial 32 can be rotated while the front and rear of the dial peripheral surface are pinched with fingertips. The printing belt 34 feeding operation and the position adjusting operation by 32 can be performed more simply and accurately.

  In addition to the above embodiment, the interlocking body 20 does not have to be configured as a cover structure that covers the left and right walls of the cover body 18, and is a rod, strip, frame, or the like that moves up and down in conjunction with at least the stamp base 4. Can be formed. In this case, the rod, the belt-like body, or the frame body can be slidably guided by a guide body 27 protruding from the cover body 18 or a guide groove (guide body 27) formed in a recess in the cover body 18. The interlocking body 20 may be configured by combining a plurality of parts. In this case, the interlocking body 20 does not have to move with the stamp table 4. For example, the interlocking body 20 may be lifted toward the interlocking body locking tool 73 when the stamp stand 4 is lowered, and the interlocking body 20 to be raised is received by a part of the interlocking body locking tool 73. Thus, it is possible to prevent the stamp stand 4 from switching to the stamp adjustment posture. The interlocking body 20 does not have to be formed as a single component, and can be formed integrally with the stamp base 4.

  The outer surfaces of the left and right walls of the cover body 18 facing the shaft end of the dial shaft 31 are preferably parallel to the rotation plane of the adjustment dial 32 in order to simplify the structure. It may be formed of a curved surface. The interlocking body 20 is preferably provided on the left and right sides of the cover body 18, but may be provided on either the left or right side of the cover body 18. The key lock does not need to be a cylinder lock, and may be any lock that can be locked or unlocked with the key 86 and can be operated to displace the interlocking body locking device 73 with the output shaft 84 at the time of locking and unlocking.

  The interlocking body locking device 73 is not limited to the structure described in the embodiment. The interlocking body locking device 73 can be engaged with the interlocking body 20 in the locked posture to prevent the interlocking body 20 from moving, and the interlocking body locking device 73 is interlocked in the unlocking posture. Any structure that releases the engaged state of the body locking member 73 and the interlocking body 20 may be used. The interlocking body guide structure is a structure in which a vertically long groove is provided between a pair of guide bodies 27 projecting from the outer surface of the cover body 18, and the slide protrusion 88 formed on the inner surface of the interlocking body 20 is slid and guided by the previous groove. The point is that the interlocking body 20 and the cover main body 18 may be structured to be able to slide up and down relatively.
