  • Patent number: 11543782
    Abstract: A timepiece is provided which ensures connection reliability and improves antenna characteristics. This timepiece includes a wristwatch case which houses a timepiece module, and an antenna which is provided on the upper surface of the wristwatch case in a discontinuous annular shape along the circumferential direction of the wristwatch case and electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case. As a result, since the antenna is electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case, the antenna and the timepiece module are unfailingly and favorably connected to each other. Accordingly, the connection reliability of the antenna is ensured and radio waves are favorably received. In addition, the reception performance and the antenna gain are improved, whereby the antenna characteristics are improved.

  • Patent number: 8786768
    Abstract: An image capturing device 100 includes three blocks, that is, a lens block 1 having an imaging lens 4, a display block 2, and a frame block 3. The display block 2 has a display unit 5 which performs display using a liquid crystal, a transparent touch screen 63 with which the display unit 5 is covered, a shutter button 61 which is disposed adjacent to the display unit 5, and a power button 62. The frame block 3 has a generally U-shaped frame form and surrounds the circumferences of the lens block 1 and the display block 2. Each of the display block 2 and the frame block 3 is coupled to the lens block 1 rotatably via a biaxial hinge unit. Especially, the display block 2 and the frame block 3 are coupled to the lens block 1 rotatably via a first hinge and second hinges.

  • Patent number: 8363126
    Abstract: In a digital camera, when the shutter is half-depressed, a controlling section 20 sequentially acquires current through-images imaged by an image acquiring section 10 which are wide-angle images imaged before zooming. Then, when a zoom operation is performed, the controlling section 20 holds a wide-angle image acquired at that point as a guidance image. Next, when the zoom magnification exceeds a predetermined magnification (for example, 3×), the controlling section 20 displays in a display section 25 the guidance image (wide-angle: low magnification) imaged before the zoom operation with a telephoto image imaged after the zoom operation. At the same time, a position corresponding to the current telephoto image is displayed to be identifiable within the guidance image. As a result, an imaging subject is easily confirmed when zooming is performed from wide-angle imaging to telephoto imaging.
