A cam piece 31 for closing is provided, and the passive piece 55 is rotated by the cam projection 30 in conjunction with the lowering of the inner cylinder 3 to shift the protective lid 6 from the closed position to the open position. .

  A fifth feature of the stamp according to the present invention is that, in addition to any of the first, second, third, and fourth features, the outer tube 2 that is raised with respect to the base tube 1 cannot be moved down. It is in the point which has a locking means for locking.

  When the seal stamp of the present invention is not used, the protective cover 6 is positioned in the closed position located below the marking surface 8 of the printing unit 4, so that the marking surface 8 is covered with the protective lid 6, It is possible to prevent ink from adhering to other objects or dust from adhering to the marking surface 8. In addition, simply by lowering the outer cylinder 2 while the lower end surface 1a of the base cylinder 1 is in contact with the paper surface or the like, the protective lid 6 is automatically moved from the closed position to the opened position in which it is retracted to the outside of the base cylinder 1. The printing unit 4 swings and the marking surface 8 of the printing unit 4 is opened, and the printing unit 4 is lowered and the marking surface 8 is pressed against the paper surface to be printed. Sealing can be performed without being obstructed by the protective lid 6.

  When the outer cylinder 2 is lowered to the position where the protective lid 6 is in the open position, the outer cylinder 2 can be automatically locked to the base cylinder 1 by the locking means 9, so the lowering operation of the outer cylinder 2 is 1 The printing unit 4 can be kept open as it is by simply performing the rotation, and the user can, for example, hold the outer cylinder 2 of the stamp, and press the stamp one after another against the paper surface, for example. It can be carried out. That is, the user can easily and quickly perform continuous marking without being bothered by the operation for continuous marking.

  In the present invention, when the outer cylinder 2 is lowered to the position where the protective lid 6 is in the open posture, the hook 77 of the lever 73 is caught by the engagement angle 78 and locked, and the biasing force of the biasing body 74 is used. Since the locking state of the hook 77 of the lever 73 is maintained, the outer cylinder 2 can be reliably locked to the base cylinder 1 by the locking means 9 and the locking state can be held with a simple configuration.

  When the outer cylinder 2 is pushed down to the lowermost position, the hook 77 of the lever 73 hits the upper wall of the engaging portion 71 (the state shown in FIG. 6) and resists the biasing force of the coil spring 74. Is pushed outward. Next, the hook 77 of the lever 73 climbs over the upper wall of the engagement portion 71 from the outside and enters the engagement groove 72 and is caught by the engagement angle 78 of the engagement portion 71 (FIG. 7). Status). As a result, the protective lid 6 is held in an open posture, and the marking surface 8 of the rubber printing body 36 of the printing unit 4 is held in a state of being located below the base cylinder 1. Therefore, the ink on the marking surface 8 of the rubber printed body 36 can be transferred (marked) continuously to the paper surface or the like.

  When the lower cylinder 1 is pressed against the paper surface by pressing the lower end surface 1a of the base cylinder 1, the marking surface 8 of the printing unit 4 protrudes below the lower end surface 1a of the base cylinder 1. 2 may not be surely lowered to the lowermost position, and the hook 77 of the lever 73 may not be easily caught by the engaging angle 78 of the engaging portion 71. In this case, for example, the outer cylinder 2 can be reliably lowered to the lowermost position by pressing the lower end of the engaging portion 71 of the locking means 9 against the paper surface or the like in a posture in which the stamp is inclined obliquely. Subsequently, the ink on the stamp surface 8 of the rubber print body 36 can be transferred to the paper surface or the like by setting the main stamp to a vertical posture with respect to the paper surface or the like.

  After completion of the continuous marking, the upper end 73a of the lever 73 is pushed toward the outer cylinder 2 against the urging force of the coil spring 74, so that the hook 77 of the lever 73 is detached from the engagement angle 78, and the spring 5 is attached. The outer cylinder 2, the inner cylinder 3, and the printing unit 4 are pushed up together by the force. Then, at the timing when the marking surface 8 of the rubber printing body 36 of the printing unit 4 finishes passing through the cover opening 11, the first contact surface 63 of the protective lid 6 comes off from the straight wall 52 of the cam projection 30, and the protective lid 6 swings. The shaft 44 rotates in the counterclockwise direction of FIG. 7 (direction toward the closed position). As the outer cylinder 2, the inner cylinder 3 and the printing unit 4 are further raised, as shown in FIG. 7, the protective lid 6 is further rotated counterclockwise, and the cam piece 31 of the inner cylinder 3 is closed. After the surface 57 contacts the second contact surface 64 of the passive piece 62 of the protective lid 6, the lower surface of the passive piece 62 is received by the stopper surface 58 of the cam piece 31, and the protective lid 6 returns to the closed state. The protective lid 6 is held in the closed position.

  When the ink on the marking surface 8 of the rubber printing body 36 is transferred (printed) to the paper surface only once, the outer cylinder 2 is maintained while the upper end 73a of the lever 73 is pushed toward the outer cylinder 2 with a finger or the like. Is pressed down to transfer the ink on the printing surface 8 to the paper surface or the like, and then the pressing force of the outer cylinder 2 is released, or the protective lid 6 is in the open position so that the ink on the printing surface 8 can be transferred to the paper surface or the like. In the state before the hook 77 of the lever 73 is hooked on the engagement angle 78 of the engaging portion 71, the ink on the marking surface 8 is transferred onto the paper surface or the like, and then the pressing force of the outer cylinder 2 is released. In these cases, since the hook 77 of the lever 73 of the outer cylinder 2 is not hooked on the engagement angle 78 of the engaging portion 71 of the base cylinder 1, the outer cylinder 2, the inner cylinder 3, and the printing unit 4 are immediately raised. At the same time, the protective lid 6 immediately returns to the closed state.

  The parts that make up the stamp are assembled in the following procedure. First, the inner cylinder 3 is inserted into the base cylinder 1 from the lower surface side, the lock body 7 is assembled to the inner cylinder 3, and the swing shaft 44 of the protective cover 6 is assembled to the bearing hole 10 of the base cylinder 1. The cylinder 1 is temporarily assembled. Next, the spring 5 is assembled between the spring holding pieces 12 of the base cylinder 1 and both 1 and 5 are inserted into the outer cylinder 2 from the lower surface side, whereby the left and right engaging claws 27 of the inner cylinder 3 are engaged with the outer cylinder 2. The inner cylinder 3 is integrated with the outer cylinder 2 by being fitted to the press-fitting portions 22 a of the mating walls 22. Thereafter, the cap 18 of the outer cylinder 2 is attached to the main outer cylinder 17. Finally, the printing unit 4 is inserted from the lower surface side of the inner cylinder 3, and the inner cylinder 3 and the printing unit 4 are press-fitted and fixed by the press-fitting engagement portion 51 (FIG. 4), thereby completing the seal. The printing unit 4 is detachable from the inner cylinder 3.

  As shown in FIG. 10, the locking means 9 is provided with a latching portion 70 at an intermediate portion in the vertical direction of the main outer cylinder 17 of the outer cylinder 2 and from the lower end of the latching section 70 to the lower end of the main outer cylinder 17. A vertically long escape groove 79 may be formed, and the engaging portion 71 may be provided at an intermediate portion in the vertical direction of the base cylinder 1. Also in this case, when the outer cylinder 2 is lowered to the position where the protective cover 6 is in the open posture, the lever 73 of the latching section 70 is in a state where the engaging portion 71 of the base cylinder 1 enters the escape groove 79. The hook 77 is caught by the engaging angle 78 of the engaging portion 71 and locked, and the hooked state of the hook 77 of the lever 73 is held by the biasing force of the spring 74. That is, the position where the latching part 70 is arranged may be other than the lower end of the outer cylinder 2, and the position where the engaging part 71 is arranged in accordance with this may be other than the lower end of the base cylinder 1.

  The coil spring 74 may be disposed between the lower end portion of the lever 73 and the outer peripheral surface of the base tube 1. In this case, the coil spring 74 pulls the hook 77 of the lever 73 toward the outer cylinder 2 as a tension spring. Further, instead of the coil spring 74, an elastic body such as a leaf spring or rubber may be arranged. Further, instead of the coil spring 74, for example, a spring integrally formed with the lever 73 may be provided.

  In addition, the latching means 9 may be provided with the latching portion 70 at the lower end portion of the base cylinder 1 and the engagement portion 71 at the lower end portion of the outer cylinder 2 in accordance with this. In this case, the hook 77 of the lever 73 of the latching portion 70 is on the upper side, and when the outer cylinder 2 is lowered to a position where the protective lid 6 is in the open position, the hook 77 of the lever 73 is engaged with the engagement portion 71. The hook 77 of the lever 73 is held by the urging force of the spring 74 while being hooked and locked by the engagement angle 78.
