Claims

[Scope of Claim for Utility Model Registration] (1) A character wheel rotatably mounted in a rectangular parallelepiped box-shaped case 1 made of an insulator with an open front, and having numbers, etc. printed at regular intervals on its cylindrical outer circumferential surface. Rotor 7 including 7e
, a slider 8 that sequentially opens and closes the contacts by slidingly contacting a fixed contact group' provided on the inner surface of a switch board 9 that is fixed to the rotor 7 and installed in the opening of the case 1; and a slider 8 that rotates coaxially with the rotor 7. a molding wheel 7b integrated with a rotor 7, and two push buttons 2 that are vertically slidably attached to opposite sides of the molding wheel 7b inside the case 1, with operating parts 2e and 3e at the upper end protruding outside the case. , 3 and the lower end bases 2f, 3f of the push buttons 2, 3 located below the model wheel 7b are branched in parallel to the shaft plate portions 2g, 3g through the long grooves 2p, 3p, and their tips are parallel to each other. The diameter of the mold wheel 7b has feeding claws 2a and 3a protruding from the inside thereof, which engage the mold wheel 7b and rotate the rotor 7 in the forward or reverse direction when the push button operation parts 2e and 3e are pressed. Elastic arm portions 2d and 3d having longer intermediate flexibility and lateral tips of the lower end base portions 2f and 3f of the push buttons 2 and 3 are integrally formed, respectively, and engage with the mold wheel 7b to rotate the rotor 7. Reversal prevention parts 2b and 3 that position intermittently one pitch at a time
b, and a coil spring 4-94 which is installed in a compressed state between the lower part of the case 1 and always urges the push buttons 2 and 3 upward.A circular recess 7h is formed on the inner surface of the case 1 of the rotor 7. A stopper 70 having the same height as the circular concave portion 7h is provided on the inner side thereof, and a rotation stopper portion 2C forming a part of the reverse rotation preventing portions 2b and 3b of the push button 2.3. 3C is made to protrude into the circular recess 7h of the rotor 7 in the normal and pressed positions of the push buttons 2 and 3, and when the push buttons 2 and 3 are pressed down, the rotation of the push buttons is stopped at a certain position of the rotor. Stopper parts 2C, 3cfJ (push-button type rotary digital switch configured to come into contact with the rotation stopper projection 7c of the o-turf).
A plurality of mounting holes 7j with the same number of teeth and the same pitch are provided on a circumference concentric with the rotania, and one or two stopper pins are installed at arbitrary positions in the mounting holes according to the specifications of the switch. 7C' Push-button type 0 according to claim 1 of the utility model registration claim, which is inserted and fixed through the hole 1r provided on the back side of the case 1.
