1. an indicating device has with keypad (12,22,32,42,52,62,72,82,92,102,112,122):

  • Key top (15,16,16b, 25,35,45,55,65,75,85,95,105,115,125)Support unit (14,24,34,44,54,64,73,74,83,84,104,114,124), it fixedly is attached with above-mentioned key top (15,16,16b, 25,35,45,55,65,75,85,95,105,115,125) on the surface that becomes the operating surface side, and with the back side of surface opposite on have the press element of pushing with the contact input part (E) of the opposed substrate in this back side (P) (14f, 24f, 34f, 44f, 54f, 64f, 74f, 84f, 94f, 104f, 114f, 124f)Magnet (11,11b), it is central authorities with press element (14f, 24f, 34f, 44f, 54f, 64f, 74f, 84f, 94f, 104f, 114f, 124f), and in the side fixed-site of this press element (14f, 24f, 34f, 44f, 54f, 64f, 74f, 84f, 94f, 104f, 114f, 124f) on support unit (14,24,34,44,54,64,73,74,83,84,104,114,124)If key top (15,25,35,45,55,65,75,85,95,105,115,125) is displaced sideways, magnet (11,11b) interlock then, with the Magnetic Sensor (13) that is located on the substrate (P), detect the variation that is displaced sideways the magnetic flux density that causes of magnet (11,11b)It is characterized in that,Between magnet (11,11b) and press element (14f, 24f, 34f, 44f, 54f, 64f, 74f, 84f, 94f, 104f, 114f, 124f), be provided with elasticity flexible portion (14d, 29,39,44d, 54d, 69,79,89,99,104d, 114d, 124d), this elasticity flexible portion allows the displacement on the pressing operation direction based on pushing up the pressing operation of (15,25,35,45,55,65,75,85,95,105,115,125) towards the key of contact input part (E).
