  • Patent number: 11848126
    Abstract: A cable stopper structure and an image forming apparatus includes a cable disposed throughout a first passage and a second passage, the second passage having a ceiling height higher than a ceiling height of the first passage, a first component disposed in the first passage and connected to one end portion of the cable, and a second component disposed near an exit of the first passage and connected to the other end portion of the cable, the second component being removable in a direction away from the first component. The cable includes a folded-back portion folded back in the second passage and a rigid portion disposed between the folded-back portion and the first component. The rigid portion has a rigidity greater than that of the cable and has a length in a pulling-out direction of the cable longer than the ceiling height of the first passage.

  • Patent number: 11815840
    Abstract: A printer includes a case including an input port for rolled paper, a cover provided to be rotatable between a closed position of the input port and an open position of the input port, a holding portion that holds the rolled paper, a biasing member that biases the holding portion in a first direction, a stopper mechanism that stops rotation of the holding portion in the first direction, and a linkage mechanism that rotates the holding portion in conjunction with the rotation of the cover. When the cover is in the closed position, the holding portion rotates in the first direction in accordance with an outer diameter of the rolled paper by a biasing force of the biasing member. When the cover rotates from the closed position to the open position, the holding portion rotates together with the cover against the biasing force of the biasing member.

  • Publication number: 20230232099
    Abstract: An image capturing apparatus capable of keeping constant the update interval of a display section even when still image photographing is performed during moving image photographing. In the image capturing apparatus, by controlling a storage time period during which display image data is stored in a storage section, a time period from a frame start to the start of displaying image data with a first resolution is made equal to a time period from a frame start to the start of displaying image data with a third resolution. Further, by controlling changing the start timing of reading out image data with a second resolution, the update interval of the display image data is kept constant.

    Abstract: According to one embodiment, in an X-ray tube, an electron convergence cup has a first surface located closer to the anode, and an electron convergence groove opening on the first surface and housing a filament. The first surface has a first edge located on the opening, and a second edge located on the opening and opposite to the first edge in a first direction. The first edge is closer to an outer peripheral part than the second edge is. When the distance between the first edge and the filament in the first direction is defined as a first distance and the distance between the second edge and the filament in the first direction is defined as a second distance, the first distance is shorter than the second distance.
