A vibration-type actuator includes a vibrator, a contact body, a pressure member, a holding member, and a base. The vibrator has an elastic member and an electro-mechanical energy conversion element fixed to the elastic member. The contact body contacts the vibrator. The pressure member presses the contact body and the vibrator in a first direction. The holding member holds the vibrator and includes a support portion and at least one fitting hole portion extending in the first direction. The support portion supports the vibrator movably in the first direction. The base holds the holding member. The contact body moves relative to the vibrator in a second direction intersecting the first direction. The base includes at least one fitting protrusion portion extending in the first direction and fits in the at least one fitting hole portion.

Vibration-type actuator and electronic apparatus including the same

An image forming apparatus acquires an input image generated by reading an image of an original document to be copied, and determination information of whether or not the input image corresponds to a blank. The image forming apparatus controls a printer to print the input image together with a page number on a sheet and output the sheet, according to a determination result indicated by the determination information. At that time, the image forming apparatus controls the printer so as to output a sheet on which the page number is not printed, with respect to the input image determined to correspond to a blank.

Image forming apparatus, image forming method, and storage medium

A vibration-type actuator can downsizes a pressing mechanism for bringing a vibrating body and a driven body into press contact with each other and generates required pressing force. The vibrating body has an elastic body, an electro-mechanical energy conversion element, and at least one projecting portion. The driven body has a driven base material that is brought into press contact with the vibrating body, and a permanent magnet joined to the driven base material. The driven base material and the elastic body face each other across the permanent magnet in a thickness direction of the elastic body. The permanent magnet is magnetized in the thickness direction of the elastic body. A magnetic action of the permanent magnet on the elastic body and the driven base material brings the projecting portion and the driven base material into press contact with each other in the thickness direction of the elastic body.

Vibration-type actuator that moves vibrating body and driven body relatively to each other, and electronic apparatus

A vibration actuator capable of determining positional relationship between a vibration body and driven body with high accuracy while keeping a pressurized contact state therebetween. The driven body contacts with the vibration body in a first direction and moves in a second direction perpendicular to the first direction. A holding member that holds the vibration body has two holes. A support member that supports the holding member has two projections that fit in the holes to form first and second fitting parts. The projection contacts with the hole in the second direction and in a third direction perpendicular to both the first and second directions in the first fitting part. The projection contacts with the hole in the third direction in the second fitting part. A contact range of the projection and hole in the third direction in the first fitting part differs from that in the second fitting part.
