Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

As shown in fig. 1-3, a character-adjustable mimeograph apparatus includes an inverted U-shaped frame 1,U, a connecting rod 2 is fixedly connected between bottom ends of two side arms of the frame 1, the connecting rod 2 is rotatably connected with seven character wheels 3, ten tooth sockets 31 are uniformly distributed on an outer circumferential surface of each character wheel 3, a character block 32 is formed on a circumferential surface of the character wheel 3 between two adjacent tooth sockets 31, numerical values of the ten character blocks 32 on each character wheel 3 respectively correspond to arabic numerals 0-9, the tooth sockets 31 are composed of a first contact surface 311 and a second contact surface 312, the second contact surface 312 and the first contact surface 311 form an included angle of 60 degrees, a support plate 12 is connected to a right side of a top arm of the U-shaped frame 1 through a connecting plate 11, the support plate 12 is parallel to an axis of the connecting rod 2, seven rollers 4 with rectangular cross sections are slidably inserted on the support plate 12, the seven rollers 4 are arranged corresponding to the seven character wheels 3 one by one and horizontally abutting against the seven character wheels 4, one roller 41 is rotatably connected to one end of the character wheel 3, a roller 41 parallel to an axis of the roller 41 of the roller and a fixed sleeve of the roller 4, a spring 4 are arranged between the slide rod 4 and a support ring 4, a spring 5 is arranged on the support plate 41, and a support ring 311, a spring 5 is arranged parallel to the support plate 31, and a spring 4, and a stop ring 311, a stop ring 31 are arranged on the support plate 31, and a stop ring 31 are arranged between the roller 5.
