Since the electric circuit of the light emitting element can be opened to keep the light emitting character in a non-light emitting state, it is possible to prevent unnecessary consumption of the battery.

According to a fifth aspect of the present invention, in the invention of the fourth aspect, the stamp main body portion forming the support main body portion includes a plurality of sub-stamp portions that can be freely attached and detached. Therefore, it is possible to play a variety of stamps while making the light emitting character emit light after exposing the appropriate stamp surface according to the taste.

Further, according to the invention of claim 6, the compression coil spring is arranged so that the switching pin and the anode side lead terminal are always kept in conduction, so that the switching pin and the anode side are connected. It is possible to more reliably control the light emission of the light emitting element while ensuring a constant electrical connection with the lead terminal.
