The convection fan filter 17 is lifted while being attracted to the front portion of the convection fan guard 16 by the magnetic force.

When the convection fan filter 17 is further lifted, the magnet separating portion 26 comes into contact with the lower surface of the convection fan guard 16.
Since the magnet separation portion 26 is bent at about 45 degrees, if the convection fan filter 17 is pulled up while the magnet separation portion 26 is in contact with the lower surface of the convection fan guard 16, the convection fan filter 17 gradually. The lower part is separated from the convection fan guard 16, whereby the lower engagement member 28 is separated from the front part of the convection fan guard 16.

  As described above, the magnet separating portion 26 formed by being bent at about 45 degrees contacts the lower surface of the convection fan guard 16, so that even if the convection fan guard 16 is pulled up, the lower engagement member 28 is magnetically driven by the convection fan. It is possible to prevent the trouble that the guard 16 is not easily removed while being adsorbed to the front portion of the guard 16, and the convection fan filter 17 can be easily removed.

  Then, as shown in FIG. 12, the upper engagement member 27 is lifted from the front portion of the convection fan guard 16 by pulling up the convection fan filter 17, and the magnet separation portion 26 of the lower engagement member 28 is in contact with the lower surface of the convection fan guard 16. Since the convection fan filter 17 is lifted up and away from the front portion of the convection fan guard 16, the convection fan filter 17 can be easily removed from the rear of the device body 1 by further lifting the convection fan filter 17 from that state.
