    摘要: A belt deviation detection device detects lateral displacement of a rotary belt in a width direction of the belt. The belt deviation detection device includes a contact member in contact with the belt at a contact portion of the contact member, a biasing member configured to bias the contact member toward the belt to press the contact member against the belt, and a displacement detector configured to detect the displacement of the belt in the width direction of the belt. The contact member is configured to track the displacement of the belt in the width direction of the belt. The contact member is made of a metal material, and a hardening treatment is applied to at least the contact portion of the contact member.

    摘要: A driving force transmission unit includes a first coupling, a second coupling, and a first rotary shaft. The first coupling includes a first contact portion and a hole, the inner circumferential surface of which has a rounded rectangular shape in cross section including a circular arc portion. The second coupling includes a second contact portion disposed at a position facing the first contact portion to contact the first contact portion along a direction of rotation of the second coupling. The first rotary shaft is connected to the first coupling and includes a shaft portion, an outer circumferential surface which has a rounded rectangular shape in cross section including a circular arc portion inserted into the hole of the first coupling.

    摘要: A floating type magnetic head for a magnetic disk drive. A slider, in which a magnetic core is incorporated, is fixed by adhesive to a gimbal with a hole formed on the side of the gimbal in contact with the magnetic core. Deformation of the magnetic core by the adhesive is prevented and the position of the magnetic core with respect to the magnetic disk is stabilized without deforming the magnetic core.

    摘要: An image forming apparatus includes an image bearer, a nip forming device, a contact-and-separation device, a thickness information retrieving device, and a controller. The contact-and-separation device moves the image bearer and the nip forming device to contact and separate from each other. The controller controls the contact-and-separation device based on information on a thickness of a recording medium obtained by the thickness information retrieving device such that in a case in which a thickness of a preceding recording medium and a thickness of a successive recording medium are different in continuous printing in which a plurality of recording media is printed out continuously, the contact-and-separation device adjusts a space between the image bearer and the nip forming device when the preceding recording medium exits the transfer nip to a preset size corresponding to the thickness of the successive recording medium that enters the transfer nip.
