DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel typewriter toy.

Conventionally, a keyboard typewriter (Japanese Patent Laid-open No. 55-44861
(see Japanese Utility Model Publication No. 37-21947), and a dial mounting device for a toy typewriter (Utility Model Publication No. 37-21947) in which the dial can be attached and detached by screwing bolts and nuts, but the former is a spare. There is a risk that the dial may play in the spare loading section and the letters may hit the inner peripheral wall of the spare loading section and be damaged, and the latter requires the nut to be turned many times when attaching or removing the dial. There were defects such as inconvenience.

The present invention provides a new typewriter toy that prevents the spare dial from playing in the spare case and causing damage to the characters, and also allows for easy attachment and detachment (replacement) of the dial. The purpose is to

In order to achieve the above purpose, the typewriter toy of the present invention has carbon paper placed on the front side of the paper wrapped around the platen on the base by a retainer plate, and the typewriter keys on the base are placed on this carbon paper. In a typewriter toy that stamps the paper by striking a dial that moves back and forth, there is a dial mounting base member 29 with a dial loading drum 30 on the top surface, and a spare dial provided on the base 1. It has loading drums 54, 54', a convex disk 49 having a loading hole 48 in the center, and is provided with type letters 51 on the outer periphery of the large diameter portion 50 of the convex disk, and has a dial loading drum 30 for use and spare letters. By fitting the dial loading drums 54, 54' and the loading holes 48, the dial mounting base member 29 and the dial 53, 53', 53'' are freely rotatably loaded on the base 1, and the dial in use is loaded. The hook-shaped part 55 for preventing the dial from being pulled out provided on the drum 30 for use, and the drum 30 for loading the dial for use.
a jump-type stopper 57 and a jagged part 56 that are provided so as to mesh with the outer peripheral surface of the dial and the inner peripheral surface of the loading hole 48 of each of the dials 53, 53', 53'' to prevent free rotation of the dial; It is something that has.

Since the present invention is as described above, when replacing the dial, first, remove the hook-shaped portion 55 for preventing extraction, and in this removed state, remove the dial 53 from the dial loading drum 30 in use. Thereafter, the dial 53' is removed from the spare dial loading drum 54, and the dial 53' is loaded onto the dial loading drum 30 for use, and then the dial 5 removed from the drum 30 for loading used dial in the above step.
3 to the spare dial loading drum 54' after removing the dial 53'.

Since the present invention is constructed as described above, it is of course advantageous in that the dial can be replaced very simply and easily by the above-mentioned procedure.
In the present invention, the spare dial can be stored by being inserted into the spare dial loading drums 54, 54' provided on the base 1, so that the dial can be stored in the spare dial loading section as in the above-mentioned conventional example. There is no risk of damage to the characters (printed type) due to play, and there is no need to worry about the dial loading drum 30 used.
It has a jumping type stopper 57 and a jagged part 56 which are provided in such a manner as to interlock with the outer circumferential surface of the dial and the inner circumferential surface of the loading hole 48 of each dial dial 53, 53', 53'' to prevent free rotation of the dial dial. Therefore, when stamping the dial loaded on the dial loading drum 30, there is no fear that the print stamped on the paper will be misaligned by the stroke of the stamp.

The illustrated embodiment has a hollow platform 1 that is convex when viewed from the side, and is provided with support walls 3 and 3' on both left and right sides above a low point 2 at the rear of the platform 1. The moving table 4 is mounted so that it can reciprocate in the left and right directions by fitting the rails 5, 5' and the grooves 6, 6', and an angle is formed between the supporting walls 3, 3' of the moving table 4.
