摘要:
An indwelling apparatus (5) for holding a capsule endoscope (3) is arranged with a control device (57) including an optical sensor (73), a control board (66) configuring a controller and a reset circuit, a driver board (68) configuring an electromagnet driver, and an electromagnet (70), where when the optical sensor (73) detects the light, the controller performs the drive control of the electromagnet (70) at every constant time interval to turn ON the reed switch (14) and supply power to the capsule endoscope (3) thereby operating the capsule endoscope (3) only when observation is necessary, and thus the battery drain of the capsule endoscope is reduced.

In a double-sided display device including a pair of substrates, self-emitting element areas formed on the pair of substrates, respectively, the self-emitting elements being provided in a sealed space formed by bonding the pair of substrates to each other, and display planes each being formed on the bottom face side of each of the substrates so as to be oriented in the opposite directions, a desiccant is provided in a space on at least one of the substrates within the sealed space. Thus, in the double-sided display device, the sealed space can be effectively used.

A display has a panel, and first and second electrodes. The first and second electrodes define a matrix of cells on the panel. The second electrodes, which correspond to lines of the cells, are scanned to select the cell lines one by one. The first electrodes are driven to set display data for a selected one of the cell lines. The display also has a sequence setting unit for setting sequences of scanning the second electrodes, and a sequence selection unit for selecting one of the sequences that minimizes the current and power consumption of a first-electrode driver without deteriorating the quality of the displayed images.
