ABSTRACT:
A digital clock in which a frame member has two opposite side end plates integrally molded with a base plate of the frame member and a separate partition plate detachably secured in position to the frame member between the two side end plates. The digital clock comprises a preliminarily assembled assembly consisting of at least an indicating flap drum and a timer setting drum supported by a driving shaft with a predetermined axial play existing between the timer setting drum and the indicating flap drum before the assembly is mounted in the frame member. Thus, the assembly can be mounted in the frame member by first inserting one end of the shaft through one of the two side end plates and then inserting the other end of the shaft through the other side end plate so as to be journaled thereby. The axial play of the assembly is removed by securing the separate partition plate to the frame member between the timer setting drum and the indicating flap drum so that the assembling of the digital clock is easily completed while the number of parts for forming the frame is held to a minimum.
