Abstract
A drive arrangement within a small electric instrument, especially a battery-operated electronic clock, includes a circuit board. Mounted on the circuit board, in addition to the electronic circuitry, are at least the static components of a motor which can be mounted on the circuit board prior to its installation. The circuit board and such static components can thus be inserted as a unit into the clock housing and into suitably designed receiving elements. The receiving elements position the circuit board, as well as the components arranged thereon, into the proper locational relation to the other parts of the motor or clock. The circuit board is held in place after its insertion into the housing by a battery contact spring which is designed in the form of a knife-edged contact and which presses laterally against the circuit board, thus holding the board in its inserted position without the need for additional fastening means. This specific type of holding of the circuit board makes possible a quick installation of same, and also a particularly simple disassembly thereof for making repairs.
