Abstract
A case for enclosing a circuit board has a housing with walls and a circuit board with a light-receiving element attached perpendicularly thereonto is inserted into the housing to be secured at a specified position. To correctly position the circuit board and to secure it at this position, parts of the walls are bent inward protrudingly such that when the circuit board is inserted, these inwardly protruding parts are elastically compressed outward. As soon as the circuit board reaches the specified position, these elastically compressed pieces spring back to their normal inwardly bent positions to prevent the circuit board from disengaging.
