An image forming apparatus includes a photosensitive drum, a developing device, a primary transfer part, a droplet ejecting unit and a controller. On the photosensitive drum, an electrostatic latent image is formed. The developing device forms a toner image by causing a developing agent to adhere to the electrostatic latent image. The primary transfer part transfers the toner image onto an intermediate transfer belt. The droplet ejecting unit ejects droplets onto the toner image on the photosensitive drum after forming the toner image on the photosensitive drum and before transferring the toner image to the transfer member. The controller controls an ejection area of the droplet ejecting unit in accordance with image information of the toner image.

The exercise assisting system includes: a display device including a display screen displaying an image to a user; a comparison image storing unit storing a comparison image representing an image of an exerciser performing a predetermined exercise; a comparison image display unit displaying the comparison image stored in the storing unit on the screen; a mirror image displaying means displaying a mirror image of the user so as to overlap the comparison image; a characteristic amount extraction unit detecting positions of sampling points of a body of the user and calculating a characteristic amount representing a posture of the user based on the position; a posture estimation unit comparing the characteristic amount from the extraction unit with a criterion amount representing a posture of the exerciser and estimating a deviation between postures of the user and the exerciser; and a presentation unit presenting an estimation result of the estimation unit.
摘要:
A printing apparatus and a conveyance control method are provided, both capable of detecting a print medium conveying state highly precisely in an entire process of conveying the print medium being printed. For this purpose, the surface of the print medium placed on the belt and the surface of the belt are detected to acquire the moving distance or moving speed of the print medium. Based on the moving distance or moving speed thus obtained, the driving of the belt is controlled. Even in a situation where the object being detected switches from the print medium to the belt in the middle of the conveying operation, the measurement of the moving distance can be performed without interruption by the same detection method using the same optical sensor unit.

This invention includes an input operation unit which accepts the operation of selecting a first or a second printing medium and outputs information indicating the selected printing medium, a conveyance path, a conveyance mechanism which conveys the selected printing medium in the conveyance direction, and a control unit. The conveyance mechanism includes a main roller, a driven roller which presses the main roller through the selected printing medium, a rotation member having a cam shape, and an elastic member which deforms to change a pressing force in accordance with the rotational position of the rotation member. The control unit rotates the rotation member to the first rotational position when the first printing medium is selected, and rotates the rotation member to the second rotational position where the pressing force becomes smaller than that at the first rotational position when the second printing medium is selected.
