Abstract: A test apparatus includes a holder that is capable of holding a test container in which a test object is to be provided, an optical measurement section that performs predetermined processing on the test object of the test container held by the holder, and a hardware processor that controls holding of the test container by the holder and releasing of the holding. In this test apparatus, the test container released from the holding moves in a gravity direction.

Abstract: An extraction apparatus is a sample removal apparatus that removes a sample collected from a living body. The extraction apparatus includes: a storage container holder that holds a storage container of a sample and is capable of being placed at a sample receiving section where the sample is supplied to the storage container, and a removal section that causes the sample to be discharged from the storage container to a predetermined place; a housing that covers the storage container holder and the removal section; and a supply section that allows for supply of the sample from the outside of the housing to the storage container in the housing.

Abstract: An extraction device includes an extraction container including a discharge port and capable of storing a biological sample and an extractant, a discharge accelerator configured to discharge the biological sample extracted into the extractant in the extraction container from the discharge port, and a controller configured to instruct the discharge accelerator to discharge the biological sample from the discharge port.

Abstract: A detection device includes a support base having a rotation surface rotatable in a plane, a detector provided on the rotation surface and displaced with rotation of the rotation surface, a first supply port and a second supply port provided above the rotation surface, and an optical measurer measuring optical characteristics of a first supply material and a second supply material supplied from the first supply port and the second supply port to the detector.

Abstract: An image forming apparatus includes: an image carrier to which a lubricant is applied; a developing device that develops an electrostatic latent image carried on the image carrier with toner, and includes a casing accommodating a toner-containing developer and a developing sleeve supplying the image carrier with the toner contained in the developer accommodated in the casing; and a hardware processor that detects information indicating a state of lubricant adhesion to the developing sleeve, and performs, based on a result of the detection by the hardware processor, a lubricant removing operation as an operation for removing the lubricant adhering to the developing sleeve.
