Description

The present invention relates to a spectrophotometer capable of storing a data file in an external storage medium such as a USB memory.

  Conventionally, in a measuring apparatus such as a spectrophotometer, data files such as measurement data and parameter data stored in a memory in the measuring apparatus are transferred to a personal computer and data processing is performed on the personal computer. As a data file transfer method, there are a method of directly connecting a measuring apparatus and a personal computer with a cable, and a method of connecting to a network via a LAN or the like. In the former method, since a personal computer needs to be installed near the measuring device, data cannot be processed by a personal computer in a separate room or a remote place. Since the latter method requires laying a LAN cable, setting a network, and the like, it takes time and cost when installing the apparatus. For this reason, a method of using an external storage medium such as a USB memory is suitable for transferring data files more easily.

  A spectrophotometer U-2900 manufactured by Hitachi High-Technologies Corporation is one of the measuring devices capable of storing data files in a USB memory (Non-patent Document 1). As shown in FIG. 1, the spectrophotometer 30 is provided with a USB port 34 on the side of the housing, and the USB memory 15 can be inserted and removed here.

Provide. Therefore, the space of the external storage medium (including the space for inserting / removing the external storage medium into / from the connection port) can be saved at least by the distance between the side surface of the spectrophotometer housing and the side surface of the operation panel. . As a result, the adjacent spectrophotometers can be placed closer to each other, or the spectrophotometers can be placed closer to the wall, so that the utilization efficiency of the spectrophotometer installation room is improved. In addition, since the external storage medium does not protrude to the front of the spectrophotometer housing, troubles such as the user of the spectrophotometer accidentally touching the external storage medium or hitting the instrument to it are prevented. .

  Furthermore, since the connection port of the external storage medium is on the side surface of the operation panel provided on the upper surface of the housing, the position of the connection port can be easily confirmed. Of course, in order to make the position of the connection port easier to understand and enable quick operation, a mark indicating the position of the connection port may be attached to the position on the operation panel immediately above the connection port.

  In the measuring apparatus according to the present invention, since the connection port is located close to the operation panel, it is possible to operate the operation panel immediately after inserting the external recording medium into the connection port, and a series of operations for measurement. Can be performed smoothly and quickly by the user.

  Note that a USB memory is generally used as the external storage medium, which is convenient. However, in addition to an existing external storage medium such as an SD memory card (registered trademark), a small size that will be defined in the future is used. Any external storage medium can be used.
