  In the presser 8, the first insertion piece 83, the second insertion piece 84, and the third insertion piece 85 are inserted into three holes penetrating the top plate 11 of the instrument body 10 in a one-to-one correspondence. Each of the first insertion piece 83, the second insertion piece 84, and the third insertion piece 85 is configured to sandwich the main piece 80 and the top plate 11. And the presser 8 is attached to the lower surface of the top plate 11 by screwing the screw inserted into the screw insertion hole provided in the top plate 11 into the female screw portion 800 of the main piece 80 (see FIG. 12).

  Here, attachment of the emergency power supply unit 5 to the appliance main body 10 will be described. As shown in FIGS. 1, 12, and 14, the emergency power supply unit 5, the control device 6, and the presser 8 are attached to the instrument body 10 along the longitudinal direction (one direction) of the instrument body 10. The emergency power supply unit 5 is disposed between the control device 6 attached to the top plate 11 of the instrument body 10 and the presser 8.

  First, as shown in FIG. 14, before the emergency power supply unit 5 is attached, the control device 6 and the presser 8 are attached to the instrument main body 10. A space for arranging the emergency power supply unit 5 is provided between the control device 6 and the presser 8.

  The emergency power supply unit 5 is accommodated in a space between the control device 6 and the presser 8 in the instrument body 10 with the case body 52 facing the top plate 11. The operator holds the emergency power supply unit 5 in the instrument body 10 by grasping the protrusion 511 of the emergency power supply unit 5. At this time, the side piece 82 of the pressing tool 8 guides the emergency power supply unit 5 closer to the top plate 11 side while aligning the instrument body 10 in the short direction. Initially, approximate alignment is performed by the tip portion 822 that is inclined outward, and then more accurate alignment is performed by the base portion 821.

  The terminal holding portion 527 of the emergency power supply unit 5 is inserted into the housing 62 through the opening 6211 (see FIG. 10) at the front end of the second housing 621. At this time, the guide piece 5271 of the terminal holding portion 527 is guided to the guide groove 6219 provided at the right end of the front surface of the second housing 621 (see FIG. 7). The first contact 57 (see FIG. 11) of the emergency power supply unit 5 is electrically connected to the first contact receiver 641 (see FIG. 10) of the control device 6. Further, the second contact 58 (see FIG. 11) of the emergency power supply unit 5 is electrically connected to the second contact receiver 642 (see FIG. 10) of the control device 6. As a result, the connector 59 (see FIG. 11) of the emergency power supply unit 5 is electrically connected to the receiving connector 64 (see FIG. 10) of the control device 6.
