摘要： Provided are an image processing apparatus, a control method, and a control program for further shortening the time required for recognition processing. An image processing apparatus includes, an operation module, a display module, an imaging module to successively generate an input image, an evaluation point calculation module to calculate, for each of the successively generated input images, an evaluation point for each of a plurality of character candidates for a character in each input image, and a character recognition module to recognize, when a character candidate whose degree of certainty based on the plurality of evaluation points calculated for each of the successively generated input images is equal to or greater than a threshold value is present, the character candidate as a character in the input image. The character recognition module terminates processing of calculating the evaluation point, even when a character candidate having the degree of certainty equal to or greater than the threshold value is not present, in a case where a predetermined condition is satisfied since processing of calculating the evaluation point starts, displays, on the display module, the plurality of character candidates in order based on the evaluation point, and sets, when one of character candidates displayed on the display module is designated by a user with the operation module, the designated character candidate as a character in the input image.

摘要： A medium conveying apparatus includes a medium tray, a feed roller to feed a medium placed on the medium tray, a brake roller facing the feed roller, a pressing member to press the brake roller to the feed roller side, a processor to detect media multi-feed, and control the feed roller and the brake roller in such a way that the medium is reset to the medium tray when the media multi-feed of media is detected. The processor controls the pressing member in such a way that a pressing force of the brake roller when resetting the medium to the medium tray is greater than a pressing force of the brake roller when feeding the medium.

摘要： A medium carrying device includes a first stopper, a second stopper, a lever, and a mechanism that, when the lever is positioned in a blocking area, places the first stopper at a first blocking position and places the second stopper at a second blocking position, when the lever is positioned in a opening area, releases the first stopper to be positioned at a first opening position and releases the second stopper to be positioned at a second opening position. When the lever is positioned at a boundary position in between the blocking area and the opening area, a lever portion of the lever gets positioned in between a first stopper portion of the first stopper positioned at the first blocking position and a second stopper portion of the second stopper positioned at the second blocking position.
