Description

  The present invention relates to a rotation stamp that is covered with a shutter member so that a printing surface of a rotation stamp provided with an endless printing belt is not exposed to the outside except during a stamping operation.

  Conventional stamps that allow continuous stamping are provided with a shutter that covers the print surface except during the stamping operation, so that the print surface is not damaged, dust is attached, and hands and clothes are not stained by the print surface. The seals to be used are known (for example, see Patent Documents 1, 2, and 3).

However, since all of those described in Patent Documents 1, 2, and 3 are fixed stamps, the shutter may be simply opened by pressing the sheath body by a stamping operation at the time of stamping. In order to change the print surface, it is necessary to operate the rotor while visually checking the print surface. In order to change such a print surface, a stamp operation is required. It is necessary to be able to open the shutter when necessary without carrying out the above, and such a rotation stamp is not yet commercially available because of its complicated structure.

Cover the rotor of the rotation mark on the body It is preferable to or forming a 蔽部. Further, the rotor of the rotation mark may be arranged in multiple upper and lower stages, or the master mark part may be formed surrounding the printing part of the endless print belt of the rotation mark.

In the present invention, since a lock mechanism that can hold the shutter member in a half-open state in which the print arrangement of the print surface can be viewed from the front end opening of the sheath body is incorporated, the print surface can be rotated by a rotation operation like a date stamp. In a rotating stamp that changes the print surface, it is possible to visually recognize the print surface by a simple operation whenever necessary without performing a pressing operation when it is desired to change the print surface. Further, the shutter member is a pair of shielding plates in which the bases are pivotally supported at opposite positions close to the distal end opening of the sheath body, and the distal ends are in contact with each other, and a stopper mechanism is formed on the inner surface of the sheath body to perform the stamping operation. and the engagement groove with the locking portion for positioning the rotary stamp in a position to open the pair of shielding plates, provided rotary stamp frame engaging to be opened stamping ready in conjunction with the lowering of the rotating indicia associated with when it shall become more and engaged by the locking pin in the groove is so that the particular operation structure is stabilized on top of easy single obtained.

  Also, if the engaging groove is formed in multiple stages in the engaging groove, the printing surface position can be moved closer to or away from the tip of the sheath body by changing the positioning position of the rotation mark, so the printing surface is cleaned. In some cases, the cleaning operation is simplified by bringing the printing surface closer to the tip of the sheath body.

Furthermore, by forming a horizontal groove that engages with the locking pin of the rotation mark frame at the upper end of the engagement groove and locks the rotation mark in the raised position, the rotation mark is inadvertently lowered so that printed surface is exposed Ri Do that there is no risk of contaminating the other material, also forming a horizontal groove to lock in the lowered position the rotary stamp locking pin engaged with the rotary stamp frame to the lower end portion of the engaging groove If this is done, it is always possible to keep the printing surface exposed from the tip of the sheath body, so it is necessary to raise the rotational stamp for each stamp when performing continuous stamping, which speeds up the stamping operation. Become.

  Furthermore, by forming a shielding part that covers the rotor of the rotation mark on the sheath body, if the rotor is covered with the shielding part when not in use, the rotor may be inadvertently rotated by hitting other objects. Thus, it is possible to accurately prevent the printing surface from being changed.

  Further, if a plurality of rotors are arranged in multiple stages, the arrangement positions of the rotors can be dispersed, so that sufficient rotor spacing can be secured and the rotor operation can be performed smoothly.

  By arranging the master mark so as to surround the print portion of the endless print belt of the rotation mark, it is possible to create various marking patterns with a changeable print surface and a fixed print surface.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a rotation stamp body with a master mark. The rotation mark main body 1 includes a rotation mark 6 in which a rotor frame 4 having a rotor 3 for rotating the endless print belt 2 is mounted on the rotation mark frame 5, and a master mark that surrounds the print portion of the endless print belt 2. 7, a sheath body 8 that covers the rotation mark frame 5, and a printing surface of the endless printing belt 2 that is provided at a position close to the opening of the end of the sheath body 8 is directed toward the opening of the end of the sheath body 8. The shutter member 9 is held in a fully closed state that is not exposed but is opened as the sheath body 8 is raised by the stamping operation.

  As shown in FIG. 21, the rotor frame 4 has bearings 4a and 4b that pivotally support the rotation shafts 3a and 3b of the rotor 3 arranged in two upper and lower stages, and the endless print belt 2 is suspended below the rotor frame 4. It is substantially U-shaped with a bridge portion 4c. By arranging the rotary shafts 3a and 3b in multiple stages, the arrangement interval of the rotors 3 can be increased, so that it is possible to accurately prevent the adjacent rotors 3 from rotating together during the operation of the rotors. Become.

  Further, as shown in FIG. 22, the rotation mark frame 5 is a stepped substantially cylindrical body composed of a small-diameter cylindrical portion 5a and a large-diameter cylindrical portion 5b by combining split-divided half members. A notch portion 5d for projecting the rotor 3 is formed on concave arc surfaces 5c formed at intervals of 180 ° on the peripheral surface of the cylindrical portion 5b. Further, a locking pin 5e, which will be described later, is formed at the upper end of the large-diameter cylindrical portion 5b so as to protrude at an interval of 180 ° with a phase shifted by 90 ° from the concave arc surface 5c.

  A gripping portion 50 is fitted to the upper end of the small diameter cylindrical portion 5 a of the rotation mark frame 5. The grip 50 is slidably inserted into the sheath body 8. Reference numeral 10 denotes an elastic member such as a coil spring. The elastic member 10 is attached between the inner surface of the top plate of the grip portion 50 and the upper end of the sheath body 8 and is attached in a direction to separate the grip portion 50 and the sheath body 8. It is fast.

  The illustrated shutter member 9 has a substantially semicircular shape in which a concave and convex edge composed of an engagement protrusion 12a and an engagement receiving edge 12b is formed at the tip, and an insertion piece 13 for attachment is formed at the other end. The shielding plates 11 and 11 are configured such that the engagement protrusions 12a and the engagement receiving edges 12b are always alternately assembled by elasticity, and the insertion of the base portion is performed. The piece 13 is inserted into the insertion grooves 80a and 80a that are arranged to face each other at an interval of 180 ° formed in the mounting cylinder 80 of the shutter member 9 provided at the distal end of the sheath body 8, and the shielding plates 11 and 11 are inserted. The shield plates 11 and 11 are fixed so that they can be pivotally supported, and the elastic edges of the shield plates 11 and 11 are alternately engaged with each other so as to conceal the printing surface at all times. The shielding plates 11 and 11 are pushed open by the contact.

  Further, the sheath body 8 is formed with long window holes 8a, 8a for exposing the rotor 3 and a shielding portion 8b covering the rotor 3, except when changing the printing surface of the stamp 6 or the rotation mark 6. The rotor 3 is shielded by the shielding part 8b so that it does not move carelessly by touching other objects. Reference numeral 15 denotes an engaging groove for engaging with a locking pin 5e of the rotation mark frame 5 formed on the inner surface of the sheath body 8, and the engaging groove 15 is formed in a horizontal groove 15a, a vertical groove 15b, and a vertical groove 15b. The horizontal groove 15a has a locking function for locking the marking operation of the rotation mark 6 and the vertical portion 15b has a function of guiding the marking operation of the rotation mark 6.

  Further, the locking portion 15c locks the locking pin 5e of the rotation mark frame 5, and the rotation mark 6 is opened to the shutter member 9, but the printing surface of the rotation mark 6 is attached to the tip of the sheath body 8. The mounting cylinder 80 is positioned at a position where it is not exposed from the tip. The locking pin 5e is locked by the elastic member 10 constantly urging the rotation mark frame 5 upward and pressing the locking pin 5e against the locking portion 15c.

Further, the horizontal groove 15a is formed at 1/4 (90 °) of the inner circumferential surface of the sheath body 8. If the sheath body 8 is rotated 90 ° clockwise, the rotor 3 is covered by the shielding portion 8b. In addition to being covered, the printing operation of the rotation mark 6 is locked, so when the horizontal groove 15a is formed at the upper end of the engagement groove 15, the printing surface is inadvertently exposed even if it is carried in a pocket or bag. Ink does not adhere to clothes or hands, and the rotor 3 is not carelessly rotated to change the printing surface. Further, if the horizontal groove 15a is formed at the lower end of the vertical portion 15b, it is possible to lock the marking state where the printing surface is exposed from the tip of the sheath body. There is no need to raise it, and the stamping operation can be speeded up. Further, if a protrusion is provided in the vicinity of the lock position of the horizontal groove 15a formed at the upper end or the lower end so that the locking pin 5e can be moved over the protrusion and disposed at the lock position, a click feeling is generated. In addition to sensing that the position has been reached, the printed surface is not exposed against the intention of the user when carrying or storing, so that other objects can be prevented from being soiled with ink.

  A tension spring 18 biases the rotor frame 4 and applies tension to the endless print belt 2. 3 c is a notch portion of the rotor 3, and 3 d is a shaft tube portion of the rotor 3 around which the endless print belt 2 is wound, and a pyramidal projection for preventing the endless print belt 2 from slipping on the outer peripheral surface of the shaft tube portion 3 d. 19 are arranged in a staggered pattern. Reference numeral 20 denotes a separator disposed between the rotors 3.

  Reference numeral 21 denotes a first ink occlusion body that supplies ink to the endless printing belt 2, and 22 denotes a second ink occlusion body that is superimposed on the first ink occlusion body 21. Reference numeral 23 denotes a display label for instructing the locking direction of the rotation mark 6 to be affixed to the grip portion 50, 24 denotes a date change position indication line display label to be affixed to the sheath 8, and 25 is affixed to the rotation mark frame 5. A display label 26 for the alignment line with the date change position supporting line 26 is an ink occlusion body for the master mark 7.

  When using such a rotation stamp, first, each rotor 3 exposed from the long window hole 8a of the sheath body 8 is appropriately rotated through the notch portion 3c so that the printing surface has a desired content. change.

  After changing the printing surface by the above operation, if the gripping part 50 is gripped and the rotation mark 6 is pushed down, the locking pin 5e of the rotation mark frame 5 is guided by the vertical groove 15b of the sheath body 8 so that the rotation mark 6 is attached. It will be lowered. By this lowering, the outer peripheral surface of the tip of the rotation mark 6 comes into contact with the shielding plates 11 and 11 of the shutter member 9 and is pushed open to open the shutter member 9. The rotation mark 6 is further lowered through the opened shutter portion 9 to expose the printing surface from the tip of the mounting cylinder 80 as shown in FIGS. 13 to 18, and the rotation mark 6 and the master mark 7 are used for marking. .

  When the printing surface of the rotation mark 6 is to be changed, the rotation mark 6 is slightly lowered with respect to the sheath body 8, and as shown in FIGS. The alignment line 25 of the rotation mark frame 5 is matched. At this time, the shutter member 9 is opened. In this state, when the rotation mark 6 is slightly rotated clockwise with respect to the sheath body 8, the locking pin 4b is locked to the locking portion 15c, and the rotation mark 6 is engaged by the urging force of the elastic member 10. The stopped state is maintained in positioning. At this time, since the printing surface is located in the sheath body 8, it is possible to prevent ink from being attached to clothes and fingers when the printing surface is changed. In this way, the printing surface is changed by rotating the notch portion 3c of the rotor 3 while viewing the exposed printing surface with the shutter member 9 opened.

  When the change of the printing surface is completed, the rotation mark 6 is slightly rotated counterclockwise with respect to the sheath body 8 to lock the locking pin 5e with the locking portion 15c of the engaging groove 15. , The rotation mark 6 is restored and raised to the old state. As a result, the shielding plates 11 and 11 of the shutter member 9 are elastically restored to shield the printing surface again.

  If the printing operation is performed in the same manner as described above after the change of the printing surface, the printing with the changed printing surface of the rotation mark 6 and the printing surface of the master mark 2 is performed.

  When the stamping is completed in this way, the locking pin 5e is locked to the start end of the horizontal groove 15a of the engagement groove 15 by rotating the sheath body 8 counterclockwise with respect to the rotation mark 6. Therefore, even if the gripping part 50 is inadvertently pressed, the stamping operation is not performed. Therefore, there is no possibility that other objects will be stained by the ink on the printing surface even if it is put in a pocket or bag. Moreover, in this state, the notch portion 3c of the rotor 3 is covered with the shielding portion 8b of the sheath body 8, so that the rotor 3 is not carelessly rotated and the printing surface is not changed, so that an unexpected change operation is performed. Thus, it is possible to reliably prevent erroneous stamping caused by the operation.

  Although one locking portion 15c is formed in the embodiment, as shown in FIG. 23, a plurality of locking portions 15c are provided so that the printing surface of the rotation mark 6 is close to the tip of the sheath body 8, and the printing surface Needless to say, cleaning or the like may be easily performed.
