Next, preferred embodiments of the present invention will be described in detail with reference to the drawings.
Reference numeral 1 denotes a stamp body. The stamp body 1 is guided by an inner frame body 3 that is slidably movable up and down in the outer frame body 2, and a reversible printing board 4 that is pivotally attached to the tip of the outer frame body 2. An ink pad case 5 for storing the ink pad 5a attached to the base end of the inner frame 3, an elastic member 6 made of a spring coil for biasing the inner frame 3 downward, and a lower end of the inner frame 3 It consists of a marking cap 7 that is held with a lid.

  The outer frame 2 is formed with locking claws 2a for locking with the inner frame 3 on the front and rear inner wall surfaces, and the locking claws 3a of the inner frame 3 and the locking claws 2a of the outer frame 2 are formed. The release lever 2b for releasing the locking lock is formed on the front and rear outer surfaces, 2c is a shaft hole for pivotally mounting the horizontal shaft 4a of the stamp board 4, and 8 is covered on the upper portion of the outer frame body 2. It is a top cover.

  Further, the inner frame 3 is formed with a longitudinal groove 3b for guiding the horizontal shaft 4a of the stamp board 4. Further, as shown in FIGS. 3, 4, and 5, the cam mechanism 9 for reversing the stamp board 4 includes a first cam 9 a formed on one side of the intermediate portion of the longitudinal groove 3 b of the inner frame 3 and the stamp board. 4 and a second cam 9b formed on the base plate. As shown in the figure, the first cam 9a has a cam curve in which an upper and lower circular arc part is connected to an intermediate concave arc part, while the second cam 9b is formed on the outer edge of the stamp board 4 and is It has a cam curve of the same shape that fits with the first cam 9a, and an arc portion is formed on the vertical center line of the horizontal shaft 4a, and left and right concave arc portions are connected to the arc portion.

  With the above-described configuration, the stamping board 4 is urged by the elastic member 6 in the non-printing state, and is positioned at the base of the inner frame body 3 protruding from the outer frame body 2, and the printing surface is set to the ink surface. Although it is in a reverse state in contact with the pad 5a, when the inner frame body 3 is slid and stored in the outer frame body 2 by the stamping operation, as shown in FIG. 3, the second cam 9b faces downward. As shown by the chain line, the concave arc portion and the upper arc portion of the first cam 9a mesh with each other like a gear, and the stamp plate 4 pivotally attached to the outer frame 2 by the horizontal shaft 4a rotates 180 degrees. The printed body faces downward and can be stamped.

  When the marking operation is completed, the inner frame 3 is lowered by the elastic member 6, and as shown in FIG. 3, the second cam that is reversed from the arc portion at the lower part of the first cam 9a is lowered. 9b meshes with the upward concave arc portion, and reverses the stamp plate 4 in the opposite direction to return to the old state. Further, when carrying or storing, if the inner face frame 3 is covered with the stamp face cap 7, the stamp face is protected by the stamp face cap 7 and the opening of the inner frame body 3 is as shown in FIG. The inner frame body 3 and the outer frame body 2 are locked and locked by the lock mechanism 10 because they are pushed upward from the marking surface of the stamp board 4.

  The locking mechanism 10 includes a locking claw 2a formed on the outer frame 2, a locking claw piece 3a that locks with the locking claw 2a formed on the inner frame 3, and an outer frame that releases the locking lock. 2, the inner frame body 3 and the outer frame body 2 are not locked and locked only by covering the inner frame body 3 with the marking surface cap 7. When the opening is pushed up by the child until the opening of the inner frame body 3 is positioned above the marking surface of the stamping board, the lock mechanism 10 is activated, and the inner frame body 3 and the outer frame body 2 are locked. For this reason, the inner frame 3 is lifted by the stamping operation until the opening is substantially flush with the marking surface of the stamping board, and the inner frame 3 is not locked to the outer frame 2. Further, the lock mechanism 10 is released by pushing the release lever 2b, whereby the locking claw piece 3a is bent inward, the locking lock with the locking claw 2a is released, and the inner frame body 3 is elastic force of the elastic member 6. The printing plate 4 is reversed and raised and comes into contact with the ink pad 5a. Due to such a configuration, even if the stamp cap 7 is removed, the locking of the inner frame body 3 and the outer frame body 2 is not released, and the stamp board 4 can be locked.

  Reference numeral 11 denotes a holding mechanism for the marking cap 7. The holding mechanism 11 includes a downwardly expanding arc-shaped recess 11 a formed on the outer surface of the lower end of the inner frame 3, and a ridge formed on the inner wall surfaces before and after the marking cap 7. 11b and a protrusion 11c formed to surround the ridge 11b. As shown in FIGS. 2 and 4, the protrusion 11c is brought into contact with the lower end edge of the inner frame 3 to form a ridge. By engaging 11b with the recess 11a, the stamp cap 7 is accurately positioned and held by the inner frame 3.

  Reference numeral 12 denotes a key mechanism, and the key mechanism 12 is a pair of left and right vertical ridges arranged side by side on the inner wall facing the lower portion of the inner frame 3 as shown in FIGS. 1, 3, 4, 5, 10 (a). 6 and 9, a pair of left and right vertical grooves 12b arranged on the opposite outer wall surface of the stamping board 4 with the horizontal shaft 4a interposed therebetween, as shown in FIGS. When the inner frame 3 is slid up and down due to the above, it is possible to prevent the slide operation of the inverted printing board 4 from becoming unstable or rattling.

  In the key mechanism 12, as shown in FIG. 10A, the left and right vertical ridges 12a of the inner frame 3 are fitted into the left and right vertical grooves 12b of the stamp board 4, respectively. It is not limited to the configuration of combining, but as in the second embodiment shown in FIG. 10 (b), the entire left and right vertical ridges 12a of the inner frame 3 are widened by the wide vertical grooves 12b of the stamping board 4. The left and right individual vertical ridges 12a of the printing plate 4 are provided in the left and right individual vertical grooves 12b of the inner frame 3 as in the third embodiment shown in FIG. 10 (c). The entire left and right vertical ridges 12a of the stamp board 4 are fitted into the inner frame 3 in the wide vertical groove 12b as in the fourth embodiment shown in FIG. 10 (d). It may be a thing.

  In this configuration, if the stamp cap 7 is removed, the inner frame 3 is projected from the outer frame 2 as shown in FIGS. The inner frame 3 is accommodated in the outer frame 2 against the urging force of the member 6. As shown in FIG. 3, the first cam 9a of the inner frame 3 and the second cam 9b of the stamping plate 4 mesh with each other and the stamping plate 4 is reversed so that the marking surface faces downward. .

  As shown in FIG. 3, when the stamp board 4 is turned downward, the inner frame body 3 is in a state where the vertical ridges 12a of the inner frame body 3 and the vertical grooves 12b of the stamp board 4 are close to each other and face each other. Since it rises, the vertical ridge 12a and the vertical groove 12b of the key mechanism 12 are engaged, and the inner frame 3 continues to rise while maintaining the engaged state. Since the vertical ridge 12a and the vertical groove 12b of the key mechanism 12 are engaged with each other, the posture of the printing plate 4 is not stably rattled. Therefore, even if the printing is performed rapidly and strongly, the printing plate 4 is displaced. Can be prevented from coming off from the inner frame 3 and the occurrence of poor engagement between the first cam 9a and the second cam 9b of the cam mechanism 9 can be prevented.

  For this reason, the stamp board 4 is stabilized, and the stable marking as shown in FIG. 5 is performed. When the marking is completed, the inner frame body 3 is lowered in a stable state under the guidance of the key mechanism 12 by the urging force of the elastic member 6, and returns to the old shape protruding from the outer frame body 2. By this return, the printing plate 4 is reversed and the printing surface is brought into contact with the ink pad 5a to deposit ink.

  Also, when cleaning the marking surface that has been soiled by long-term use or replacing the printing body, the outer frame body 2 and the inner frame body 3 can be removed by removing the printing surface cap 7 without operating the release lever 2b. Since the lock 4 remains locked, and the stamp board 4 is locked in the inverted state with the marking surface facing downward, the marking surface 7 exposed downward may be cleaned or the printing body may be replaced. When the stamping operation is performed again, if the release lever 2b of the outer frame body 2 is pressed, the locking lock is released, and the inner frame body 3 is lowered by the urging force of the elastic member 6, and via the cam mechanism 9. Since the printing plate 4 is reversed and the printed body is brought into contact with the ink pad 5a, if the stamping operation is performed, the printing plate 4 on which ink has newly adhered to the printing surface is reversed and lowered to perform a clear marking.
