  Thereafter, the protruding portion 35 of the cradle 29 is inserted in correspondence with the long hole 30a of the mounting portion 30 (FIG. 10), and the cradle 29 is slid horizontally to attach the cradle 29 to the mounting portion 30.

  Then, the handset 28 to which the handset cord 33 is attached is placed on the table 29, and the connection terminal 33a of the handset cord 33 is inserted into the second insertion port 38 of the table 29 (FIG. 2). Thereby, the attachment of the handset unit 27 to the image forming apparatus main body 2 is completed.

  Incidentally, as shown in FIG. 14, the handset unit 101 includes a handset 102 and a table 103, and the table 103 is placed on a support table 105 protruding integrally with the image forming apparatus main body 104. Conventionally, the handset 102 is placed on top. In this conventional example, the modular cord 107 that extends from the image forming apparatus main body 104 and is connected to the handset cord 106 of the handset 102 protrudes from the handset unit mounting portion, so that it does not look good.

  However, in the present embodiment, the housing recess 31 is formed on the bottom surface of the cradle 29, and the modular cord 32 is housed in the housing recess 31 so as not to jump out, so that the appearance can be improved. .

  Moreover, since the elastic curled part 32b curled spirally is formed in the middle part of the modular cord 32, the modular cord 32 can be easily wired by extending the curled part 32b at the time of wiring. On the other hand, after the wiring, the modular cord 32 is contracted to the original shape, so that the modular cord 32 can be easily accommodated in the housing recess 31, and the wire processing of the modular cord 32 can be performed quickly.

  Furthermore, since the holding piece 34 protrudes from the receiving recess 31 and the holding state of the modular cord 32 is held by the holding piece 34, the modular cord 32 can be reliably received in the receiving recess 31.

  Further, the notch 36 is formed on one end side (left end side in FIGS. 3 to 5) of the housing recess 31, and the width W1 of the notch 36 is longer than the slide stroke of the table 29. When the cradle 29 is slid and attached to the attachment portion 30, the linear portion 32c on the proximal end side of the modular cord 32 can be prevented from being bitten.

  Furthermore, since the image forming apparatus main body 104 does not have the support base 105 on which the mounting base 103 as in the conventional example is placed, the packaging space can be reduced accordingly.
