Reference numeral 1 denotes an upper outer cylinder holder, 2 denotes a lower outer cylinder holder, and the upper outer cylinder holder 1 and the lower outer cylinder holder 2 are relatively rotatable by a cylindrical connector 3 as shown in FIGS. Are connected to each other to form an outer cylinder holder.

  As shown in FIGS. 14 to 17, the upper outer cylinder holder 1 is formed with a vertical notch 1a for sliding and guiding the clip 5b of the knock cap 5 in the upper part of the peripheral wall, and the wall thickness thereof is varied in three stages so that the inner diameter is large, medium and small. An outer flange 6a of a lock member 6 described later is fitted and locked to the lower large inner diameter portion 1b and the upper portion of the cylindrical connector 3 is fitted.

  A serrated cam 11 is formed at the step between the small inner diameter portion 1c and the inner inner diameter portion 1d of the upper outer cylinder holder 1, and a vertical groove 1e extending upward from the inclined surface of the serrated cam 11 has a small inner diameter. It is engraved in the part 1c at intervals of 90 °. 1f is an annular groove formed on the inner peripheral surface of the lower end portion of the upper outer cylinder holder 1, and the annular groove 1f is engaged with the upper annular ridge 3c of the cylindrical connector 3 so that the connector 3 The cylinder holder 1 is connected to be freely rotatable.

  As shown in FIGS. 8 to 13, the lower outer cylinder holder 2 is formed with notches 2 a and 2 a for attaching the shutter 4 in the lower part, and an annular groove 2 b having a concave arc shape in cross section is formed on the inner peripheral surface of the upper end. In addition, one vertical ridge 2c having a circular arc cross section is formed at the top. The aforementioned annular groove 2b is engaged with the lower annular ridge 3d of the connector 3, the vertical ridge 2c is engaged with the vertical groove 3e of the connector 3, and the lower outer cylinder holder 2 and the connector 3 are connected to each other to prevent rotation.

  As shown in FIGS. 18 to 20, the connector 3 is formed by forming a short inner cylinder 3 b following the outer cylinder 3 a, and an outer annular surface of the outer cylinder 3 a has an upper annular ridge 3 c having an arcuate section and an arcuate section. The lower annular ridge 3d, the vertical groove 3e having a concave arc shape in the lower portion, and slits 3g are formed at intervals of 90 °. The slit 3g provides elasticity to the upper tube portion of the connector 3 to facilitate assembly with the upper outer tube holder 1. In addition, concave notches 3f are formed on the inner peripheral surface of the inner cylinder 3b of the connector 3 at intervals of 180 °. The concave notch 3f engages with a key 9c formed on a shaft 9b of the print body holder 9 to be described later so that the print body holder 9 is not rotated but can be slid.

  Reference numeral 6 denotes a lock member. As shown in FIGS. 21 to 23, the lock member 6 is a cylindrical body in which an outer flange 6a is formed at the upper end and an inner flange 6b is formed at the lower end. Recessed notches 7 that are slide-guided by engaging with the keys 9c of 9b are formed at intervals of 180 °. Reference numeral 8 denotes concave notches formed in the outer casing 6a. The concave notches 8 are formed at intervals of 180 °, and the vertical ridges are formed at intervals of 180 ° on the upper portion of the large inner diameter portion 1b of the upper outer cylinder holder 1. The lock member 6 is locked to the upper outer cylinder holder 1 by engaging with the strip 1g. By the engagement / disengagement of the key 9c of the printing body holder 9 and the concave notch 7 of the inner collar 6b, the knocking operation of the printing body holder 9 is locked or unlocked.

  The printing body holder 9 is formed with a printing body receiving tube portion 9a in which the printing body 10 is detachably fitted at the lower part, and a shaft 9b connected to the knock cap 5 and the knock mechanism 13 at the upper part. Yes. The printing body holder 9 is slidably inserted into the lower outer cylinder holder 2 so that the printing surface of the printing body 10 can be exposed from the lower end opening of the lower outer cylinder holder 2. Keys 9c formed in the axial direction at intervals of 180 ° are formed on the shaft 9b. The key 9c has a substantially middle portion separated by a notch 9d and has two upper and lower stages. Through the cutout 9d, the concave cutout 7 of the lock member 6 is engaged / disengaged with the key 9c. When the concave notch 7 is engaged with the key 9c, the print body holder 9 can slide.

  The knock mechanism 13 includes a fixed cam cylinder 14 and a rotating cam cylinder 15 attached to the shaft 9b. The fixed cam cylinder 14 has a serrated cam 16 formed at the lower end edge of the flange portion 14a. Reference numeral 17 denotes vertical ridges formed at intervals of 90 ° on the outer peripheral surface of the flange portion 14a. The vertical ridges 17 are slidably engaged with vertical grooves 1 e formed at intervals of 90 ° on the inner surface of the small inner diameter portion 1 c of the upper outer cylinder holder 1.

  Locking claws 18 are formed at intervals of 180 ° on the outer peripheral surface of the cap-shaped portion 14b of the fixed cam cylinder 14, and the locking claws 18 are formed at intervals of 180 ° formed at 5b of the knock cap 5. The fixed cam cylinder 14 and the knock cap 5 are integrated with each other by engaging with the engaging hole 5c.

  The rotating cam cylinder 15 is composed of a large-diameter cylinder part 15a and a small-diameter cylinder part 15b, and four cams 19 whose upper ends are inclined on the top surface of the large-diameter cylinder part 15a are spaced at 90 ° intervals. It is formed. The small diameter cylindrical portion 15b is pivotally supported by the cap-shaped portion 14b of the fixed cam cylinder 14 so as to be rotatable. The cam 19 is engaged with the serrated cam 16 of the fixed cam cylinder 14. For this reason, when the rotating cam cylinder 15 descends and the cam 19 comes out of the vertical groove 1e of the upper outer cylinder holder 1, the rotating cam cylinder 15 is rotated by the fixed cam cylinder 14 and locked to the adjacent sawtooth cam 16. Thus, the advancement state of the printing body holder 9 is maintained. When knocking is performed again, the cam 19 of the rotary cam cylinder 15 is disengaged from the serrated cam 16 and rotates and enters the vertical groove 1e, so that the print body holder 9 is retracted by the spring pressure of the spring 20 described later. , Will return to the old state.

  Reference numeral 20 denotes a spring interposed between the lock member 6 and the rotary cam cylinder 15, and the spring 20 returns the print body holder 9 to the old state after the marking operation. Further, as shown in FIG. 34, the shutter 4 is formed by resin-molding the shielding plate 4b at an angle of about 90 ° with respect to the mounting plate 4a attached to the notch 2a of the lower outer cylinder holder 2. When the font body 10 descends together with the printing body holder 9 and comes into contact with the shielding plate 4b, the printing body 10 is forcibly opened by elasticity to expose the printing surface of the printing body 10 to the outside. Further, if the printing body 10 is retracted, the shielding plate 4b automatically returns to the old state due to elasticity.

  In such a configuration, the upper outer cylinder holder 1 and the lower outer cylinder holder 2 are connected to each other through a cylindrical connector 3 so as to be rotatable relative to each other. If the cylinder holder 1 and the lower outer cylinder holder 2 are gripped and rotated relatively, the lock member 6 that is prevented from rotating around the upper outer cylinder holder 1 rotates relative to the lower outer cylinder holder 2. It will be.

  Since the print body holder 9 is fixed to the lower outer cylinder holder 2 via the connector 3, the lock member 6 is rotated by 90 °, and the concave notch 7 formed in the inner collar 6b of the lock member 6 is marked. The print body holder 9 is unlocked by moving into the key 9c through the notch 9d of the font holder 9, and a knock operation is possible.

  If the knock cap 5 is pressed in this state, the print body holder 9 is lowered and the lower part of the print body holder 9 forcibly opens the shielding plate 4a of the shutter 4 to expose the lower end of the print body 10. Therefore, it can be stamped.

  Further, if the knock cap 5 is pressed in a state where it can be stamped, the cam 19 of the rotary cam cylinder 15 is disengaged from the saw-tooth cam 11 and rotates into the vertical groove 1e as described above. The printing body holder 9 is retracted by the spring pressure of the spring 20 and returns to the old shape, so that the printing surface of the printing body 10 is concealed inside the lower outer cylinder holder 2 and exposed. There is no risk of soiling other objects on the seal.

  Further, when the upper outer cylinder holder 1 and the lower outer cylinder holder 2 are gripped and rotated relative to each other with the printing body holder 9 retracted, the lock member 6 that is prevented from rotating around the upper outer cylinder holder 1 is used. Because of this, the print body holder 9 is locked in the raised state, and even if the knock cap 5 is accidentally pressed, the print body holder 9 cannot be slid. Therefore, the print body holder 9 is lowered and the lower end printing surface is exposed. There is no risk of polluting other things.
