  • Patent number: 7248305
    Abstract: An LCD module is associated with a pair of switches, one of which is depressed by pressing the LCD module to swivel in a seesaw operation. The LCD module has a front panel having a larger thickness than and thus capable of protecting the LC layer and the rear panel against a reasonable external load for pressing the front panel for switching. The LCD module is suited for use in a portable terminal having a smaller space for switches and LCD module.

  • Patent number: 7076058
    Abstract: A first and a second unit 1 and 2 with components mounted thereon in correspondence to respective function blocks, into which portable telephone set functions are grouped, are capable of being slidably moved between a stacked state position and an extended state position. The first unit 1 includes a first component-mounted part having a display 5 and a receiver 4. The second unit 2 includes a second component-mounted part, which is covered when the stacked state position is brought about and exposed when the extended state position is brought about. The second unit 2 has a notch 9, in which a first and a second auxiliary unit 11 and 12 are provided. A desired component-mounted part can be exposed and operated by causing selective sliding of the first and second units 1 and 2 and the first and second auxiliary units 11 and 12.

  • Publication number: 20040204202
    Abstract: A housing improves the operability of a mobile phone in a sliding structure. With the mobile phone having the front unit and the back unit in the shortened state, a phone book can be searched with the phone number information about the partner, icon information, etc. displayed on the display portion, and the mobile phone enters the expansion state. In the control portion, when the expansion detecting portion detects the change from the shortened state to the expansion state according to the output signal of the magnetic sensor, the display contents on the display portion are determined, and it is determined whether or not the phone number information or the information relating to the phone number information (for example, an image, an icon, the phone book information such as a name, etc.) is displayed on the display portion.
