Patent number: 5805945Abstract: An electronic still video camera has an electro-developing recording medium. As soon as an optical image is formed on the medium, the image is recorded and developed as a visible image therein. The developed image is electronically read as image data by a line sensor, and the read image data may be stored in an IC memory card, a floppy disk, a hard disk or the like. Optionally, the read image data may be transferred from the camera to an external device such as a computer, a TV monitor or the like. The developed image can be thermally erased from the medium by using an electric heater. One of these operations is executed by a depression of a single switch in accordance with a mode-selection switch.Type: GrantFiled: December 22, 1995Date of Patent: September 8, 1998Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventor: Harumi Aoki

Patent number: 5793031Abstract: An encoded symbol reader for reading and decoding an image of an encoded symbol is capable of operating in three modes and has a CCD, a display, and a light source. In each mode, the reading of an encoded symbol is initiated by a trigger switch. In the first mode, the CCD, display and light source are continuously driven and remain in an ON state. In the second mode, the CCD, display and light source are turned OFF when a decoding operation is completed after the trigger switch is released. In the third mode, the CCD, display, light source are turned OFF after a predetermined period has elapsed after the decoding operation is completed and the trigger switch is released. While operating in the third mode, during the predetermined interval, the re-reading of another symbol can be immediately executed without having to wait for the components to warm up.Type: GrantFiled: November 20, 1995Date of Patent: August 11, 1998Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Nobuhiro Tani, Harumi Aoki, Keiji Sawanobori
