2. Description of the Related Art Conventionally, there has been known a seal called a penetrating stamp that does not require ink to be adhered at the time of stamping using a porous stamping material having continuous pores such as sponge rubber capable of storing ink.
This type of seal is equipped with a removable cap to protect the marking surface, but it is cumbersome to remove the cap every time it is printed, and the hand touches the marking surface when removing it. There were problems such as dirty or lost caps.

  In order to solve such a problem, for example, a seal with a lid as shown in the back of Utility Model Registration Publication No. 2519833 has been devised by the present applicant. However, there is still the trouble that an operation for opening and closing the lid is necessary, and there is a dissatisfaction that the material is easily deteriorated because it is deformed when the lid is opened. In addition, there is a seal with a rotary lid for smooth opening and closing of the lid, but there is a problem that it is difficult to assemble the lid. In addition, when the seal is carried, there are problems that the lid is carelessly opened and stains the surroundings, or the stamp surface is scratched or dust is attached. Furthermore, there is a problem that when it is necessary to replenish the print body with ink or to replace the seal unit itself, the lid becomes an obstacle and the operation is difficult.

  The present invention solves the above problem, that is, it is convenient that the lid is automatically opened only by the vertical movement of the outer cylinder with respect to the inner cylinder at the time of printing, and it is not deformed when the lid is opened. There is no worry, and the lid is locked so that it does not open carelessly when you carry the seal, causing the lid to open carelessly, causing the surroundings to become dirty, scratching the marking surface, or attaching dust. Can be prevented. Furthermore, when the ink is replenished to the printing body or the seal unit itself is replaced, the lid can be locked in the expanded state so that the work can be easily performed.
