Description

  The present invention relates to a stamp such as a date stamp.

  Conventionally, there has been a stamp that uses a porous material on the printing surface, impregnated with ink on the printing surface, and allows the stamp to be continuously stamped several times without using the ink stamp for each stamp. Are known. In such a stamp, for example, in Patent Document 1, an ink storage mat that is an ink supply body is built in a stand, and when not in use, a printing surface is brought into contact with the ink storage mat, and ink is transferred from the ink storage mat to the printing surface. It is configured to replenish ink by permeating.

In such a stamp that sucks ink from the ink supply body and incorporates it, if the ink supply body comes into contact with the periphery of the printing surface, the ink adheres to the area other than the printing surface and becomes dirty at the time of printing. In order to cope with this, it is conceivable that the contact surface (ink supply surface) of the ink supply body with the print surface has the same surface area as that of the print surface. When the surface area is small, the surface area of the ink supply surface of the ink supply body is also reduced, so that the height of the ink supply body is increased to some extent in order to ensure the amount of ink stored.

The cylinder end portion 2a is provided with a printing surface for forming an imprint on the printing medium. The printing surface is orthogonal to the axial direction of the main body case 2 and is formed in a substantially circular shape. The printing surface 111 can be used to form an imprint of an arbitrary date or the like by combining a printing surface 111 whose imprint is invariable and a number or a symbol. By combining with 211, one imprint can be formed. Further, a cap 10 that is a lid for covering and protecting the print surfaces 111 and 211 when the date stamp 1 is not used is detachably provided to the main body case 2 from the cylinder end 2a side.

  A rear end portion 205 of the movable printing portion 200 (see FIG. 3) is exposed from a cylindrical end portion 2d opposite to the cylindrical end portion 2a of the main body case 2. As shown in FIG. 2, when the main body case 2 is held and the rear end portion 205 is rotated about 180 degrees in the circumferential direction with respect to the main body case 2, the movable printing portion 200 is rotated together with the rear end portion 205. Then, the slide type operation unit 221 is exposed from the opening 2b opened in the outer peripheral surface of the main body case 2. As will be described later, the operation unit 221 is for changing a plurality of print surfaces 211.

  As shown in FIG. 3, the main body case 2 accommodates a moving printing unit 200 that holds the printing surface 211 and a fixed printing unit 100 that holds the printing surface 111. The fixed printing unit 100 includes a fixed printing body 112 (see FIG. 4) on which a printing surface 111 is formed, an ink storage body 113 (see FIG. 4) that supplies ink in contact with the fixed printing body 112, and fixed. A base 120 that holds the printing body 112 and the ink storage body 113 and is fitted to the inner periphery of the cylinder end 2 a of the main body case 2 is provided. In order to close the opening of the cylinder end 2a by the fixed printing unit 100 in a state in which the movable printing unit 200 is accommodated in the main body case 2, two spiral grooves 121 are provided on the outer periphery of the base 120. Yes. The spiral groove 121 is engaged with two bosses 2 c projecting so as to face each other from the inner periphery of the cylinder end 2 a of the main body case 2. The fixed printing body 112 corresponds to the second printing body of the present invention.

  Further, two pairs of guide members 123 project from the inside of the base 120 of the fixed printing unit 100 in the direction opposite to the printing surface 111. Between the pair of guide members 123, two guide pieces 232 projecting on the lateral side surface of the holding body 230 of the movable printing unit 200 described later are sandwiched. For this reason, the moving direction of the fixed printing unit 100 is regulated so as to be slidable only in the axial direction with respect to the moving printing unit 200. That is, when the boss 2 c is slid along the spiral groove 121, the fixed printing unit 100 is moved in and out of the main body case 2 in the axial direction.

  A pair of protrusions 122 are provided on the side surface of the portion where the base 120 holds the fixed printing body 112 (see FIG. 4) and the ink storage body 113 (see FIG. 4). In addition, a substantially rectangular exposure hole 114 that penetrates the fixed printing unit 100 in a direction orthogonal to the surface of the printing surface 111 is formed in the approximate center of the printing surface 111 of the fixed printing unit 100. The exposure hole 114 is a hole for exposing the printing surface 211 of the movable printing body 210 from the main body case 2. The protrusions 122 described above are provided on the side surfaces of the base 120 on both sides of the exposure hole 114 in the short direction.

  The moving printing unit 200 supports a holding body 230 holding a moving printing body 210 in a cylindrical support case 201. The movable print body 210 is provided on the outer peripheral surface of the five belt bodies 220 that are supported individually in parallel along the longitudinal direction of the substantially long plate-like holding body 230, along with the rotation of the belt body 220. The position is fixed so that it can be moved. The movable printing body 210 is provided in a protruding manner on the outer peripheral surface of the belt body 220, and a plurality of printing sections 212 having a printing surface 211 at the front end thereof are arranged in the rotation direction of the belt body 220. The base portion of the printing unit 212 is connected. The moving print body 210 corresponds to the first print body of the present invention.

  The moving print body 210 is formed of an ink impregnated body such as a porous resin. The surface of the moving printing body 210 opposite to the surface on which the printing unit 212 is protruded, that is, the surface facing the belt body 220 (the inner surface of the moving printing body 210) is located in the moving printing body 210. A bleed-out preventing structure for preventing the permeated ink from oozing out and adhering to the belt body 220 is provided. For example, the process of closing the hole by melting the inner surface of the moving printing body 210 with heat or chemicals, the process of closing the hole by applying an adhesive or the like to the entire inner surface of the moving printing body 210, or the movement A process such as pasting a film or the like on the entire inner surface of the printing body 210 to close the hole is performed.

  Further, on the outer peripheral surface of the belt body 220, an operation unit 221 that operates when each belt body 220 is individually rotated protrudes, and the operation unit 221 is slid along the longitudinal direction of the holding body 230. Thus, the belt body 220 can be rotated.

  As described above, since the support case 201 shown in FIG. 3 is accommodated in the main body case 2, the support case 201 is formed in a cylindrical shape in accordance with the inner periphery of the main body case 2. Four long and narrow groove-shaped guide grooves 202 are opened along the line. In a state in which the holding body 230 is accommodated in the support case 201, the respective operation portions 221 of the five belt bodies 220 are changed from the same guide groove 202 with respect to the operation portions 221 of the two belt bodies 220 at the ends. The operation part 221 of the belt body 220 is projected from the independent guide groove 202 to the outside of the support case 201. Furthermore, as shown in FIG. 2, in a state where the support case 201 is accommodated in the main body case 2 and the printing surface 211 can be changed, all the four guide grooves 202 are exposed from the opening 2b.

  Next, as shown in FIGS. 3 and 4, the fixed printing unit 100 holds the fixed printing body 112 and the ink storage body 113 by the cylindrical base 120, and the printing surface 111 of the fixed printing body 112 is It is exposed face up. The ink storage body 113 is made of, for example, a porous resin, and can store ink by soaking the ink inside. The fixed printing body 112 is also made of a porous resin, and the printing surface 111 is exposed while being compressed in a state where the imprinted portion of the fixed printing body 112 is masked as is known, and the exposed portion is dissolved. It is formed by closing the hole. The fixed printing body 112 receives supply of ink from the ink storage body 113. Further, the cap 10 is fitted to the main body case 2 so as to sandwich the protrusion 122 from the side, and protects the exposed print surface 211 of the fixed print body 112 and the movable print body 210. Further, as will be described later, the cap 10 holds the ink supply body 12 in the central wall 11.

  Next, as shown in FIGS. 5 to 7, a substantially rectangular wall 11 is provided in the center of the cap 10 having a side surface 10 a raised from the edge of a circular flat plate, and printing of the movable printing body 210 is performed. An ink supply body holding unit 15 that holds the ink supply body 12 that supplies ink to the surface 211 is configured. Two ribs 14 are provided on the inner side of the wall 11 constituting the long side from the upper end of the wall 11 to the back surface of the cap 10 (the bottom surface of the ink supply body holding portion 15).

  The ink supply body 12 is inserted into the ink supply body holding portion 15 along the rib 14. When the cap 10 covers the printing surfaces 111 and 211 and is attached to the date stamp 1, the ink supply body 12 contacts the printing surface 211 of the moving printing body 210 exposed from the exposure hole 114 and supplies ink. Perform (see FIG. 4). The ink supply body 12 is made of a member that can be stored by soaking ink such as felt or urethane. Ink supply to the printing surface 211 is performed from the ink storage body 113 of the fixed printing unit 100, but when the cap 10 is attached, ink is directly supplied from the ink supply body 12 to the selected printing surface 211. It can be performed. Thereby, since the ink permeates into the selected printing unit 212 smoothly from two directions, the imprinting is not easily blurred when continuous marking is performed.

  Further, the ink supply body 12 is configured to protrude from the height of the wall 11 (see FIG. 4). At the time of non-printing, this protruding portion always abuts on the printing surface 211 of the movable printing body 210 at a position slightly behind the exposure hole 114. At this time, the size of the outer periphery of the protruding portion of the ink supply body 12 is smaller than the size of the inner periphery of the exposure hole 114 so that the ink supply body 12 does not touch the inner wall of the exposure hole 114. ing.

  As shown in FIG. 7, the ink supply body 12 is held in the ink supply body holding portion 15 by the rib 14. Therefore, the rib 14 is not limited to the one extending from the upper end to the lower end of the wall 11, and may have a length that can hold the ink supply body 12. Since the rib 14 contacts the side surface of the ink supply body 12, a gap 13 is formed between the wall 11 and the ink supply body 12. The gap 13 becomes a passage through which air enters and exits the ink supply body 12. When the ink is replenished by the air entering and exiting in this way, the ink is surely infiltrated to the vicinity of the back surface of the cap 10. The side surface (the side surface corresponding to the short side) that does not contact the rib 14 of the ink supply body 12 may contact the wall 11, but the size of the ink is such that a gap 14 a is left between the wall 11 and the wall 11. The supply body 12 may be formed. If formed in this way, an air passage can be secured on the side without ribs. The rib 14 corresponds to the first rib of the present invention.

  Further, as shown in FIG. 8, ribs 16 may also be provided on the back surface side of the cap 10 surrounded by the wall 11, that is, on the bottom surface 20 of the ink supply body holding portion 15. The rib 16 prevents the ink supply body 12 from being in close contact with the back surface of the cap 10, and a gap is also formed between the back surface of the cap 10 and the ink supply body 12. The rib 16 has only to be high and long enough to form a gap between the back surface of the cap 10 and the ink supply body 12, and is limited to one extending from one side of the wall 11 to the other side. I can't. A gap formed by the rib 16 between the bottom surface of the ink supply body 12 and the bottom surface 20 of the ink supply body holding portion 15 is an air passage formed between the wall 11 and the ink supply body 12. Since the air is communicated with the gap 13, the air can enter and exit more smoothly, and the ink can be surely soaked into the ink supply body 12 when the ink is replenished. Here, the rib 16 corresponds to the second rib of the present invention. The number of ribs 14 is not limited to two at each long side as in this embodiment, but may be one or three or more, or may be provided at the short side. The position does not have to be just opposite.

  Further, as shown in FIG. 9, a groove 17 may be formed in the wall 11. The groove 17 ensures an air passage between the wall 11 and the ink supply body 12, and allows air to enter and exit the ink supply body 12. Therefore, as in the case of providing the ribs 14 described above, when ink is replenished to the ink supply body 12, the ink soaks into the vicinity of the back surface of the cap 10 with certainty. The positions and the number of the grooves 17 are not limited to two illustrated positions and two per one long side, but may be provided on the short side or may be three or more. The groove 17 corresponds to the first groove of the present invention.

  Further, as shown in FIG. 10, a groove 18 communicating with the groove 17 may be formed on the bottom surface 20 of the ink supply body holding portion 15. The number and position of the grooves 18 are not limited to those shown in FIG. This groove 18 allows air to smoothly enter and exit in addition to the case of only the groove 17, and ensures that ink permeates into the ink supply body 12 when ink is replenished. The groove 18 corresponds to the second groove of the present invention.

  Further, instead of providing ribs or grooves on the wall 11 or the bottom surface 20, a convex portion 19 may be provided on the side surface of the ink supply body 12 facing the wall 11 as shown in FIG. 11. Thus, when the convex part 19 is provided, the convex part 19 and the wall 11 come into contact with each other, so that a gap is formed between the main body of the ink supply body 12 and the wall 11, and this gap becomes an air passage. Thus, a passage through which air enters and exits the ink supply body 12 is secured. As the air enters and exits in this way, the ink supply body 12 is surely infiltrated to the back surface of the cap 10 when the ink is replenished. The convex portion 19 corresponds to the first convex portion of the present invention.

  Furthermore, as shown in FIG. 12, in addition to the convex portion 19, a convex portion 21 may be formed on the surface of the ink supply body 12 that faces the bottom surface 20 of the ink supply body holding portion 15. Due to the convex portion 21, the ink supply body 12 does not adhere to the back surface of the cap 10, and a gap is also formed between the back surface of the cap 10 and the ink supply body 12. The convex portion 21 only needs to have a height and a length that allow a gap to be formed between the back surface of the cap 10 and the ink supply body 12, and extends from one side to the other side of the bottom surface of the ink supply body 12. It is not limited to things. A gap formed by the convex portion 21 between the bottom surface of the ink supply body 12 and the bottom surface 20 of the ink supply body holding portion 15 is an air passage formed between the wall 11 and the ink supply body 12. Since the air is communicated with a certain gap, the air smoothly enters and exits, and ink permeation into the ink supply body 12 is surely performed when the ink is replenished. Note that the convex portion 21 corresponds to the second convex portion of the present invention.

  In addition, as shown in FIG. 13, a recess 22 may be provided on the side surface of the ink supply body 12 that faces the wall 11 for use. The recess 22 is formed so as to extend from the surface that contacts the printing surface 211 of the ink supply body 12 to the surface that faces the bottom surface 20. The recess 22 ensures an air passage between the wall 11 and the ink supply body 12, allowing air to enter and exit the ink supply body 12. Therefore, when the ink supply body 12 is replenished with ink, the ink soaks into the vicinity of the back surface of the cap 10 with certainty. The position and the number of the recesses 22 are not limited to two as shown in the figure and one long side, but may be provided on the short side or may be three or more. The recess 22 corresponds to the first recess of the present invention.

  Furthermore, as shown in FIG. 14, a recess 23 that communicates with the recess 22 may be formed on the surface of the ink supply body 12 that faces the bottom surface 20 of the ink supply body holding section 15. The number and positions of the recesses 23 are not limited to those shown in FIG. This recess 23 allows air to smoothly enter and exit in addition to the recess 22 only, and ensures that ink permeates into the ink supply body 12 when ink is replenished. The recess 23 corresponds to the second recess of the present invention.

  As described above, the date stamp 1 of the present embodiment is held by the printing unit 212 selected from the plurality of printing units 212 by moving the position of the moving printing unit 210 by the rotation of the belt body 220. It is located on one side surface of the body 230, and can imprint a seal by combining the imprint by the printing surface 211 of the printing unit 212 and the imprinting by the printing surface 111 of the fixed printing unit 100. The moving printing body 210 is made of an ink impregnated body, receives ink from the ink storage body 113 of the fixed printing section 100, and the printing surface 211 exposed to the outside from the exposure hole 114 of the fixed printing section 100 has a date stamp. 1 is supplied with ink from an ink supply body 12 built in the cap 10. The ink supply body holding section 15 that holds the ink supply body 12 is formed by the ribs 14 and the grooves 17 between the wall 11 and the ink supply body 12, or by the convex portions 19 and the concave portions 22 formed in the ink supply body 12. The passage is formed, and when ink is replenished to the ink supply body 12, air can enter and exit the ink supply body 12, so that the ink can sufficiently permeate.

  Needless to say, the present invention can be modified in various ways. For example, although the movable printing body 210 is made of a porous resin, it is not limited to this and may be made of porous rubber, metal, ceramics, or the like. Further, the ink supply body 12 may be composed of a member such as urethane, paper, sponge, thread, or cloth.

  In addition, the movable printing body 210 can be replaced, and a single printing surface may be configured in combination with the printing surface 111 of the fixed printing unit 100. Further, the exposure hole 114 for exposing the printing unit 212 of the movable printing body 210 is not limited to a hole, and may be a notch or the like, and the side surfaces of the fixed printing body 112 and the ink storage body 113 are connected to the printing unit 212. What is necessary is just to become the structure which opposes.
