Patent Issued for Sliding-Type Mobile Electronic Device

July 16, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- A patent by the inventor Kitamura, Nobuyuki (Osaka, JP), filed on March 25, 2011, was published online on July 1, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8768422 is assigned to KYOCERA Corporation (Kyoto, JP).

The following quote was obtained by the news editors from the background information supplied by the inventors: "A sliding-type mobile phone includes a device main body configured by slidably connecting a first cabinet to a second cabinet, an operation portion configured by a plurality of operation keys are arranged on a front surface of the first cabinet, and a display portion configured by a liquid crystal display panel is arranged on a front surface of the second cabinet (for example, see Patent Document 1). The device main body relatively moves the first cabinet and the second cabinet in the sliding direction to make it possible to change a state between a closed state in which both the cabinets are closed such that at least a part of the operation portion is covered with the second cabinet and an open state in which both the cabinets are opened such that an entire area of the operation portion is exposed.

"In the sliding-type mobile phone, a flexible lead is connected to an electric constituent such as the liquid crystal display panel mounted in the second cabinet, and the flexible lead is drawn from a rear surface of the second cabinet, thereafter, passed through an opening formed through the front surface of the first cabinet, and connected to a circuit board incorporated in the first cabinet (for example, see Patent Document 2).

"More specifically, the first cabinet is configured by engaging a front-surface-side case half body that forms the front surface of the first cabinet to a rear-surface-side case half body that forms the rear surface of the first cabinet, an opening through which the flexible lead passes is formed in the front-surface-side case half body, and the circuit board is installed in the rear-surface-side case half body.

"In the assembling step for the sliding-type mobile phone, the flexible lead drawn from the rear surface of the second cabinet is caused to pass through the opening of the front-surface-side case half body, and the tip end of the flexible lead is then connected to a connector on the circuit board. Thereafter, the front-surface-side case half body and the rear-surface-side case half body are engaged to each other to form the first cabinet."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "Problems to be Solved by the Invention

"In this case, in order to facilitate assemblage of the sliding-type mobile phone such as connection of the flexible lead to the connector on the circuit board, a linear dimension of the flexible lead is set to be larger than a minimum linear dimension required for the flexible lead in an assembling state. Thus, in the assembling state, the flexible lead has an additional portion (to be referred to as an excessive portion hereinafter). The excessive portion of the flexible lead is stored in the first cabinet. As a result, a part of the front surface of the circuit board is covered with the excessive portion. For this reason, on the front surface of the circuit board, an electronic component cannot be mounted in a region covered with the flexible lead.

"It is an object of the present invention to provide a sliding-type mobile electronic device that can be easily assembled and can reduce restrictions of circuit design.

"Means for Solving the Problems

"A sliding-type mobile electronic device according to the present invention includes a first cabinet in which a circuit board is incorporated, a second cabinet that is slidably connected to the first cabinet, in which an electric constituent is mounted, and a flexible lead drawn from the electric constituent, passed through an opening provided in the first cabinet, and connected to the circuit board, the flexible lead having an overlapped portion in which a part of the flexible lead is folded on a predetermined region provided on a front surface of the circuit board.

"In the sliding-type mobile electronic device, in order to facilitate assemblage of the sliding-type mobile device such as connection of the flexible lead to the circuit board, a linear dimension of the flexible lead is set to be larger than a minimum linear dimension required for the flexible lead in an assembling state. Thus, in the assembling state, the flexible lead has an excessive portion. The excessive portion of the flexible lead is stored in the first cabinet. As a result, a part of the front surface of the circuit board is covered with the excessive portion.

"In the sliding-type mobile electronic device, the excessive portion of the flexible lead is folded on the predetermined region provided on the front surface of the circuit board. In this manner, the flexible lead has an overlapped portion in which the excessive portion is overlapped on the predetermined region.

"Therefore, even when a linear dimension of the excessive portion of the flexible lead increases, a region of the front surface of the circuit board covered with the flexible lead can be suppressed from spreading from the predetermined region to the outside. Thus, a region in which an electronic component is mounted does not decrease on the circuit board. As a result, restrictions of circuit design can be reduced. The linear dimension of the excessive portion of the flexible lead is increased to make it easy to assemble the sliding-type mobile electronic device.

"Effects of the Invention

"The sliding-type mobile electronic device according to the present invention can be easily assembled and can reduce restrictions of circuit design."
