  • Publication number: 20200147974
    Abstract: In a state in which a liquid storage body is installed in a liquid ejecting apparatus, at least part of the upper edge of a liquid storage section and at least part of the lower edge of the liquid storage section are in contact with a case and a first inner surface of the liquid storage section and its second inner surface opposite to the first inner surface are separated from each other. The liquid storage section is structured so that as a liquid is supplied, the first inner surface and second inner surface gradually approach each other and, at the same time, come into contact with each other from top to bottom, forming, at the bottom of the interior of the liquid storage section, a liquid flow path through which the liquid flows from the liquid storage section to the liquid supply section.

  • Patent number: 10567706
    Abstract: An interface module 61 relays control signal communication between a main CPU 621 and a light source control CPU 651 and between the main CPU 621 and a camera head CPU 242. The interface module 61 includes an FPGA 610 having CPU I/Fs 611 to 613 that correspond to communication schemes of CPUs 621, 651, and 242, respectively, and first and second storage units 615 (617) and 616 (618). The FPGA 610 relays a control signal between the main CPU 621 and the light source control CPU 651 and between the main CPU 621 and the camera head CPU 242, while temporarily storing the control signal in the first and the second storage units 615 (617) and 616 (618). Moreover, a first communication timing and second and third communication timings are set at timings shifted from one another.
