[0022]
A cap 52 is detachably fitted to the head of the grip sleeve 4.
[0023]
FIG. 19 is a longitudinal front view of the second embodiment. The first embodiment is different from the first spring receiving sleeve 53 and the second spring receiving seat 54 in that the structure of the first coil spring 55 is different. Or it is the same structure as the 1st Example shown in FIG.
[0024]
In the second embodiment, an upward spring receiving seat 56 and a downward spring receiving seat 57 are formed on the upper and lower surfaces of the flange portion 58 of the first spring receiving sleeve 53, and the vertical interval is set short. .
[0025]
As a result, the first coil spring 55 has a structure formed integrally with the second coil spring 59 by the spring wire 61 extending from the end portion 60 of the second coil spring 59. The manufacturing process and assembly man-hours for the two coil springs 2 can be saved, and the structure can greatly reduce the cost.
[0026]
The second spring seat 19 in the first embodiment uses the upper end of the cylindrical wall of the base case 7 as a spring seat, but in the second embodiment shown in FIG. The structure is different in that it is a spring seat 54 of a short cylindrical structure that is seated on the upper end of the cylindrical wall and is appropriately fixed with a structure. According to this structure, it is possible to select a material that can withstand the hard use of the seal case, and to extend the service life of the seal case. In FIG. 19, reference numeral 63 denotes a presser spring of the seal stamp 65 inserted into the inner sleeve 64.
[0027]
When the seal case 1 of the present invention is held in the state shown in FIGS. 1 and 2 with fingers and the grip sleeve 4 is pushed down by a height H, the first spring receiving sleeve 17 is gripped as shown in FIG. The first coil spring 13 is released from the contracted state and extends to the free state together with the sleeve 4.
When the grip sleeve 4 is further pushed down, the step 4A on the upper inner surface of the sleeve 4 comes into contact with the shoulder step 3A of the inner sleeve 3, and the inner sleeve 3 moves downward together with the grip sleeve 4 while compressing the second coil spring 20. To do. At this stage, the vibration when the second coil spring 20 is detached from the recesses 21 and 22 on the outer peripheral surface of the inner sleeve 3 is transmitted to the fingers as a click feeling, and the operator is made to feel that the process proceeds to the marking process.
[0028]
Due to the downward movement of the grip sleeve 4, the cam shafts 38 and 39 of the swing arm 25 are guided by the arcs of the arc grooves 34 and 35 into which the cam grooves 37 are initially inserted, and are rotationally displaced as shown in FIG. The long holes 28 and 29 of the swing arm 25 are rotated and displaced around the short support shafts 30 and 31 of the base case 7.
[0029]
When the grip sleeve 4 is moved downward, the swing arm 25 is guided to the arc grooves 34 and 35 of the cam grooves 40 and 41, and the swing arm 25 is in a substantially horizontal position as shown in FIG. Rotate to position.
[0030]
When the grip sleeve 4 is further moved downward, as shown in FIG. 6, the second coil spring 20 is compressed, and the cam shafts 38 and 39 of the swing arm 25 are aligned with the straight grooves 36 of the cam grooves 40 and 41 of the grip sleeve 4. Then, the grip sleeve 4 and the inner sleeve 3 are moved down until the stamp surface 6 of the stamp 2 contacts the stamp surface, and the stamp is completed.
[0031]
After completion of the stamping, when the seal case 1 is moved away from the stamping portion while holding the grip sleeve 4, each member returns to the position shown in FIG. 1 and FIG. In the process, when the state shown in FIG. 4 is reached, the repulsive force of the first coil spring 13 extending in the free state has an action of preventing the grip sleeve 4 from retreating, so that the second coil spring 20 is in the first state. The first coil spring 13 is returned to the contracted state shown in FIG. 2 via the spring receiving sleeve 17, and a part of the repulsive force of the second coil spring 20 is exhausted due to this action, and the remaining repulsive force Thus, the vermilion of the seal case 5 comes into contact with the stamp face of the seal 2.
[0032]
【The invention's effect】
According to the first aspect of the present invention, since the second coil spring is disposed between the grip sleeve and the inner sleeve in which the seal is housed, it is possible to directly feel the feeling of operation of the seal at the time of stamping. The effect that the feeling of use of the seal case is good can be achieved.
[0033]
Further, the first coil spring and the second coil spring perform opposite finger movements of expansion and compression at the time of stamping and at the time of restoration, so that no spring sag occurs at the same time. Even when the coil spring hangs, the repulsive force of the remaining coil springs provides an effect that can be repeatedly printed.
[0034]
Furthermore, since the second coil spring compresses the first coil spring against the repulsive force by a part of the repulsive force during the return operation after the stamping, the vermilion of the seal case is elastically applied to the seal surface. The repulsive force to be contacted is weakened by the repulsive force required for compressing the first coil spring, and it is possible to prevent the sacrificial sag due to contact with the marking surface with an unnecessarily strong force. There is an effect that it can be set to a desired value depending on the magnitude of the repulsive force of the coil spring.
[0035]
According to the invention of claim 2, the vibration when the wire of the second coil spring is pulled out from the concave portion having a substantially semicircular cross section formed in the inner sleeve is transmitted to the fingers gripping the grip sleeve, whereby the stamping process There is an effect that the user can perceive as having a crisp feeling of entering.
[0036]
According to the invention of claim 3, the vertical position of the stamp surface of the seal is determined by the vertical movement of the adjusting screw in the space guarded by the outer surface of the upper end of the inner sleeve and the inner surface of the upper end of the grip sleeve. Since it can be adjusted only when it is pushed down or moved up only by the vertical movement space between the two, it is possible to prevent an unexpected change in the vertical position of the marking surface by touching a finger or the like during a stamping operation or the like.
[0037]
According to the invention of claim 4, since the recessed surface portion of the grip sleeve provided with the cam groove for guiding the seal case to the working position and the retracted position is covered with the covering plate, In addition, it is possible to wipe away the fear that dust or the like may enter the seal case from the cam mechanism and cause malfunction, and the appearance can be improved.
[0038]
According to the invention of claim 5, since the first coil spring and the second coil spring are formed into a continuous single body by the same spring wire, the manufacturing process and assembly man-hour of both the first and second coil springs In addition to being able to reduce costs and the like, it is possible not only to reduce costs, but also to achieve effects such as easily achieving stabilization of spring holding properties.
