An explosion-proof structure includes a partition wall that partitions a sealed space in a container and wiring that connects the interior and the exterior of the sealed space. The partition wall includes a filling portion through which the wiring passes. The filling portion includes an inner peripheral wall surface that defines an opening having a central axis that passes through the partition wall, a filler that seals a gap between the inner peripheral wall surface and the wiring, a first peripheral groove provided on the inner peripheral wall surface and filled with the filler, and a second peripheral groove provided on the inner peripheral wall surface and filled with the filler. This explosion-proof structure is capable of improving the seal of the filling portion.

A data processor for processing, recording and/or displaying data obtained from an object being examined, comprising a plurality of detachable units formed of functional blocks connected together by communication cables; a carriage driver using a screw to improve character print quality and resolution; a plurality of input units which convert signals obtained from the object into digital output signals; a control unit comprising a plurality of connectors attached to the respective input units and an arithmetic/communication device having information about positions at which the connectors are mounted and collecting signals obtained from the object and arithmetically processing the signals, and storage device wherein results of the arithmetic processing are stored; wherein the control unit processes data obtained from the object using signals tored in the storage device, and produces the recording and/or display; and wherein the character printing portion of the control unit comprises a support and driver for driving the carriage, with the support holding the carriage on which the recording head is carried so that the carriage can move across the paper, and wherein the driver comprises a motor and a screw connected to the motor shaft, and a nut mounted on the carriage and meshed with the screw. Advantageously, the functions can be flexibly increased or decreased as desired, and the number of components can be flexibly decreased so that the entire system has a greatly increased efficiency, economy, and reliability.
