  As shown in FIG. 1, in the electronic apparatus 1 of this embodiment, two modules 3 are detachably attached to a housing 2 that is a main body. The housing 2 is formed in a rectangular thin box shape, and an insertion portion 4 into which the module 3 is inserted is recessed on the upper surface. Two connectors 5 are provided on the bottom surface of the insertion portion 4, and a latching portion 6 formed of a pair of two recesses or holes is formed at the lower part of the opposite side surface of the insertion portion 4.

  As shown in FIG. 2, the two modules 3 are formed in the same shape, and are inserted into the insertion portion 4 in a state of being closely arranged in the longitudinal direction of the housing 2. A gripping member 7 for holding the module 3 is attached to two opposite positions of each module 3. The gripping members 7 are located on both sides in the arrangement direction of the modules 3, and as shown in FIG. 3, the gripping members 7 can be grasped with two fingertips and attached to the housing 1.

  As shown in FIG. 4, the case 8 of the module 3 is configured by combining a base 9 and a cover 10 with screws 11, and a holding member 7 and a circuit board 12 are accommodated inside the case 8. On the upper surface of the circuit board 12 (lower surface in FIG. 4), electronic components such as an electronic circuit 13 and an LED 15 having different functions are provided for each module 3, and a plug 14 is mounted on the back surface of the circuit board 12. The plug 14 is connected to the connector 5 of the housing 2 so that a signal line is established between the electronic circuit 13 and an internal electronic component (not shown) of the housing 2.

  As shown in FIG. 5, the gripping member 7 is formed entirely of resin, and includes a claw portion 16 that engages with the latching portion 6 of the housing 2 and a pair of arm shapes that urge the claw portion 16 in the engagement direction.
