摘要： A device for reading out an optical code includes a camera, an image memory for storing images taken by this camera, and an image processor for decoding an optical code contained in an image taken by the camera. A plurality of images are obtained continuously with the camera under specified image-taking conditions in response to a specified image-taking command, and the obtained images are stored on the image memory. The images stored in the image memory are sequentially selected one at a time in a specified order, and the image processor makes an attempt to decode an optical code contained in the selected image. Results of decoding are outputted if the attempt to decode any of the stored images is successful. The interval at which the images are taken is changed according to the number of images successfully decoded taken continuously in the past.

摘要： A powder-amount detection device includes a first electrode, a second electrode, a third electrode and a voltage detector with the second electrode adjacent to the first electrode on the powder container and have a smaller surface area than a surface area of the first electrode. The third electrode is on a side opposite to the second electrode with the powder container interposed between the third electrode and each of the first electrode and the second electrode. The voltage detector detects voltages of the first electrode and the second electrode by detecting charging and discharging behaviors of the first electrode and the second electrode when a voltage is applied between the third electrode and each of the first electrode and the second electrode for a short time, and detects the amount of powder in the powder container based on the voltages of the first electrode and the second electrode.
