Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation switch device for various measuring instruments including analytical instruments such as gas chromatographs and spectrophotometers and test measuring instruments for material testing.

[0002]

2. Description of the Related Art Conventionally, a switch for controlling the operation of this type of measuring instrument and the display of measured values, and for turning the operation on and off is usually operated by operating a switch device attached to the main body of the measuring instrument. Recently, a sheet type switch has been widely used as this switch, and a switch having a smaller size and a lighter weight has appeared. In these cases, the switch is also integrally attached to the main body of the measuring machine. As a non-integral case, a sheet-type switch is installed inside the cover and opening / closing lid of the main body. Further, there is also a system in which a lead wire is connected to the measuring machine body as a separate type switch so that the measuring machine body cannot be operated remotely.

[0003]

Various analytical instruments are usually installed on a so-called desk of an analysis machine for analysis work, and even in the case of test equipment, a test machine is so placed on a so-called desk of a test machine. Work is often done. In the case of large analytical instruments and test instruments, their bodies themselves may be installed on the floor of the measurement room. By the way, in the measurement work with these measuring instruments, the functions of the measuring instruments, the switch for controlling the operation of the measured value display and the switch operation such as the power on / off switch are performed. There are postings to record notes. These operations cannot be performed on a so-called desk on which the measuring instrument body is placed, and it is unavoidable to perform it on a desk slightly away from the stand. Therefore, the measurer often moves back and forth between the measuring device body and this desk during measurement. This causes a decrease in work efficiency. When the switch device is connected to the measuring instrument main body by a lead wire, its length is limited, and the interposition of the lead wire hinders the measurement work. The present invention provides an operation switch device that solves these problems.

[0004]

The operation switch device provided by the present invention employs a remote operation type operation switch system for transmitting and receiving a signal by a radio signal. The operation switch device is attachable / detachable to / from the recess formed in the measuring machine body, especially because of its peculiarity as a measuring device, and at least the signal receiver installed in the measuring machine body has the operation switch device detached from the measuring machine body. When operated, the signal from the signal transmitter of the operation switch device can be received. As an example of configuring so that the signal from the signal transmitter of the operation switch device can be received when the operation switch device is detached from the measurement device main body, the receiver part is exposed in the recess itself formed in the measurement device main body. Method and operation When the operation switch device is detached from the measuring instrument main body, the receiver appears in conjunction with its operation.

[0005]

The operation switch is wireless and the lead wire is omitted. Further, when the operation switch device is detached from the main body of the measuring machine, the signal receiver installed in the main body of the measuring machine becomes ready to receive a signal from the signal transmitter of the operation switch device.
