  • Publication number: 20140205880
    Abstract: Erroneous insertion of a battery into an imaging device resulting from downsizing of the battery is prevented. In a battery loading and unloading mechanism for loading and unloading a battery 2 formed in a flat rectangular parallelepiped and having an almost square main surface to and from a device (an imaging device 1) to be detachably equipped with the battery 2, the battery 2 is formed with projecting portions 26, 27 at longitudinal both ends of a back surface thereof and along the back surface, the back surface being a surface opposite to an insertion surface of the battery inserted into the device, whereby even the battery formed in a flat rectangular parallelepiped and having the almost-square main surface can be prevented from being erroneously inserted into the device.

  • Patent number: 8785022
    Abstract: A secondary battery for an electronic appliance, including a battery cell. The battery cell has a positive electrode, a negative electrode, and an electrolyte in a pack. A positive electrode terminal and a negative electrode terminal are led out from the same side face of the pack. A metallic battery can accommodates the battery cell therein such that the side face from which the positive electrode terminal and the negative electrode terminal are lead out is faced towards the opening side. A lid, made of a synthetic resin, in which terminal parts to be connected to the electrodes of the electronic appliance upon being connected to the positive electrode terminal and the negative electrode terminal are faced outwardly, plugs the opening of the battery can, the battery cell being accommodated in the battery can upon being adhered onto an inner face thereof.

  • Patent number: 8755020
    Abstract: A region of the first substrate and the second substrate enclosed by a sealant is a rectangle. The rectangle includes a central region, a pair of first regions between which the central region is interposed in a major-axis direction of the rectangle, a pair of second regions between which the central region is interposed in a minor-axis direction of the rectangle, and a peripheral region that surrounds the central region, the pair of first regions, and the pair of second regions. The spacers are disposed in the central region and the peripheral region except the pair of first regions and the pair of second regions. In the peripheral region, a width from each of the first regions to one long side of the rectangle in an outward direction is larger than a width from one of the second regions to the one long side in the outward direction.

  • Patent number: 8709633
    Abstract: In a battery loading and unloading mechanism, a battery formed in a flat rectangular parallelepiped and having an almost square main surface is loaded and unloaded to and from a device. The battery is formed with projecting portions at longitudinal both ends of a back surface thereof and along the back surface, whereby the battery can be prevented from being erroneously inserted into the device. The projecting portion has an inclined surface acutely inclined with respect to the back surface, and when the battery is unloaded from the device, unloading of the battery from the device is accelerated by the inclined surface undergoing contact pressure of the retaining means. The device is formed with a notched portion which is adapted to expose the other projecting portion of the battery when the battery is loaded, thereby facilitating unloading of the battery.

  • Patent number: 8493533
    Abstract: Light leakage between pixel electrodes over a video signal line in a TN-type liquid crystal display device in which a dot inversion driving is applied with a three o'clock viewing angle is prevented. Pixel electrodes (PX) are formed on both sides of a video signal line (DL) of a first substrate (SUB1), and an end of the pixel electrode (PX) and the video signal line (DL) overlap each other. Over a second substrate (SUB2), a black matrix (BM) is formed in a portion corresponding to the video signal line (DL). By shifting the black matrix BM and the video signal line DL to the left with respect to a gap G between the pixel electrodes PX, it is possible to prevent light leakage caused by a disclination line (DS) which occurs by a horizontal electric field between pixel electrodes (PX).
