Abstract: In this urine flow meter, a water wheel which is caused to rotate by a flow of urine from a urine flow passage tube is provided at a lower end side of the urine flow passage tube. The shape of a tip portion of the urine flow passage tube that causes urine to hit on the water wheel constitutes a nozzle part in which the tip-side is acutely processed, and an opening is formed in a sidewall surface of the tip-side. A guide is provided in a urine flow passage and is disposed in such a way that a tip of the guide is elongated as far as a tip-side region of the mine flow passage tube. The water wheel is caused to rotate by the flow of urine, and the urine flow rate can be detected on the basis of the rotation detection information.

Abstract: A medium transport apparatus includes: a frame; a table including a placement surface on which a medium is placed, a first end portion, and a second end portion, the table extending from the first end portion to the second end portion and being rotatable about a first shaft portion parallel to the placement surface; a first rotor arranged adjacent to the first end portion of the table; a second rotor arranged adjacent to the second end portion of the table; a belt that is stretched by the first rotor and the second rotor, and is configured to rotate circularly and to transport the medium in a first direction from the first end portion toward the second end portion; and a biasing part that links the frame and an attachment part provided between the second end portion and the first end portion of the table, and that biases the table.

Abstract: A developer-adhesive body unit is detachably mounted to an image forming apparatus. The developer-adhesive body unit includes a developer-adhesive body having a surface to which a developer adheres, a cleaning member that removes the developer from the surface of the developer-adhesive body, a developer storage portion storing the removed developer, and a contact portion contacting the surface of the developer-adhesive body at an upstream side of the cleaning member in a moving direction of the surface of the developer-adhesive body. A contact-and-separation unit causes the surface of the developer-adhesive body and the contact portion to separate from each other when the developer-adhesive body unit is mounted to the image forming apparatus and the surface of the developer-adhesive body moves. The contact-and-separation unit causes the surface of the developer-adhesive body and the contact portion to contact each other when the developer-adhesive body unit is not mounted to the image forming apparatus.
