Matches up, down, left, right. Further, in the drawings attached to the present specification, for the sake of illustration and ease of understanding, the scale, the vertical / horizontal dimensional ratio, the shape, and the like may be changed from the actual ones and expressed schematically for the sake of convenience. It is an example and does not limit the interpretation of the present invention.

  The recorder 1 according to the present invention includes data indicating changes in a physical quantity of an object to be measured measured by a measuring unit 100 composed of various sensors (data such as temperature, current, voltage, or strain, hereinafter collectively referred to as data). This is a hybrid recorder that records “measurement data” in two ways: an analog method for recording on chart paper and a digital method for storing and displaying measurement data.

  The recorder 1 is a first recording unit that records measurement data measured from an object to be measured on a long chart paper as a recording medium in a housing 1a having a door 2 that can be opened and closed on the front of the device. An analog recording unit 10 and a digital recording unit 20 that is a second recording unit that stores the acquired measurement data and displays a chart on the screen are provided. The recorder 1 also includes a power supply unit 30 that supplies driving power necessary for driving the recorder 1 from an external power source, an internal power source such as a primary battery or a secondary battery, and the like.

  In this apparatus, the analog recording unit 10 is disposed above the housing 1 a and the digital recording unit 20 is disposed below the analog recording unit 10. This is to secure the capacity of the storage unit 13 that stores the recorded chart paper recorded by the analog recording unit 10.

  The door 2 is provided on the front surface of the housing 1a so as to be openable and closable so that the inside of the apparatus is opened via a rotation shaft (not shown), and maintenance such as replenishment of chart paper or ink replacement of the recording member 11b is performed. It is opened and closed when performing. In addition, the recording state of the recording unit 11 of the analog recording unit 10 (that is, the waveform drawing or hitting state of the recording member 11b with respect to the chart paper) and the paper feed state of the chart paper are visually recognized from the outside of the device on the door 2 in real time. In order to make it possible, a window portion 2 a made of a transparent material (transparent resin such as glass or acrylic) is formed at a position facing the analog recording unit 10.

  As shown in FIG. 1, the window portion 2 a has a rectangular shape that is long in the width direction at the top of the door 2, and in addition to the recording state of the recording means 11 and the paper feed state of the chart paper, The attached scale is also formed in a size that can be visually recognized. A display unit 21 of a digital recording unit 20 to be described later is disposed below the door 2 (below the window 2a).

  As described above, the recorder 1 according to the present invention has a recording state on the chart paper by the analog recording unit 10 from the window 2a formed on the door 2 (for example, when the recording means 11 is a pen, waveform drawing on the chart paper). And the paper feed state of the chart paper by the paper feed mechanism 12 can be confirmed at the same time. Therefore, since the recording state and paper feeding state of the analog recording unit 10 can be confirmed in real time, even if a trouble such as a jam of the chart paper or a malfunction of the recording unit 11 occurs, it can be dealt with immediately.

Further, since the window 2a is formed on the door 2, the recording state on the chart paper by the analog recording unit 10 above the door 2 and the trend display of the measurement data by the digital recording unit 20 below the recording state. At the same time, it can be visually confirmed, and the opening / closing operation of the door 2 for the confirmation work as in the conventional product becomes unnecessary.

  The analog recording unit 10 is the same as the analog recording unit mounted on a conventional recorder, and has a recording means 11 for recording measurement data on the recording surface (front surface) of the chart paper, and a chart paper. A paper feed mechanism 12 that conveys in one direction and a storage unit 13 that stores the recorded paper on which measurement data is recorded are provided.

The drive control of each unit of the analog recording unit 10 is performed by the control unit 23 described later, but a configuration including a control unit dedicated to the analog recording unit 10 may be employed.

In addition, the analog recording unit 10 is provided with a scale plate 14 detachably according to the measurement data, and a pointer 11 c provided on the scale plate 14 moves as the recording means 11 moves. It becomes an index of measurement data.

  The recording means 11 is movable relative to the chart paper along a main scanning direction (left-right direction in FIG. 1 or front / depth direction in FIG. 2) orthogonal to the sub-scanning direction that is the chart paper feed direction. The carriage 11a includes a carriage 11a and a recording member 11b that records measurement data on a chart paper such as a dot used for the dot type and a pen used for the pen type.

  The carriage 11a can move to the same width as the chart paper in the width direction along the slide axis. When the carriage 11a moves a predetermined amount in the width direction based on the measurement data measured by the measurement unit 100, the carriage 11a is moved accordingly. The recording member 11b to be supported also moves left and right in the width direction. Measurement data is recorded on the recording surface of the chart paper conveyed at a predetermined speed by moving the recording member 11b to the left and right as the carriage 11a moves.

  The recording member 11b includes an ink storage unit that stores ink for recording measurement data on the chart paper, and one or a plurality of recording members 11b are provided depending on the number of measurement targets and the number of input channels. The recording member 11b is configured with a dot for recording measurement data when the recording method for the chart paper is a dot type, and is configured with a pen for measuring data recording when the recording method is a pen type. The recording member 11b moves on the chart paper transported at a predetermined speed as the carriage 11a moves, and continuously or intermittently records changes in measurement data.

  The paper feed mechanism 12 conveys the chart paper to the storage unit 13 in a state of contacting the recording member 11b while rotating the chart paper in one direction. The transport speed by the paper feeding mechanism 12 may be transported based on a preset transport speed (default value) or may be appropriately defined based on measurement data or measurement time (period).

  The storage unit 13 is a container for storing the recorded chart paper conveyed by the paper feed mechanism 12, and the recorded chart paper conveyed as shown in FIG.

  The digital recording unit 20 is the same as a digital recording unit mounted on a conventional recorder, and as its configuration, a display unit 21 that graphically displays measurement data, a storage unit 22 that records measurement data, and a display The control unit 23 performs display control of the unit 21 and the setting unit 24 performs various settings based on measurement and display contents.

  The display unit 21 is composed of a display device such as a liquid crystal display or an inorganic / organic EL display, and displays the trend data in accordance with the recording state of the analog recording unit 10 under the control of the control unit 23. In addition, the display unit 21 can display desired data among the acquired measurement data retroactively, or can display arbitrarily selected data among the displayed measurement data in parallel or superimposed. . As described above, since past arbitrary measurement data can be displayed on the display unit 21, it is possible to save the trouble of expanding and confirming the recorded chart paper.

  The storage unit 22 includes a main storage device including various semiconductor memories such as a ROM (Read Only Memory) and a RAM (Random Access Memory), and an auxiliary storage device such as a flash memory and an HDD (Hard Disk Drive). Measurement data measured by the measurement unit 100 and computer programs and application software necessary for driving each unit of the recorder 1 are stored.

  The control unit 23 is configured by a processor such as a CPU, a ROM, and a RAM. When an analog signal corresponding to a physical quantity is input from the measurement unit 100, the control unit 23 performs predetermined processing on this signal and stores it in the storage unit 22 as measurement data. The control unit 23 performs drive control of each unit of the digital recording unit 20 such as display control of the display unit 21 in addition to data recording processing for the storage unit 22.

In the present embodiment, the control unit 23 has been described as a configuration requirement of the digital recording unit 20, but in addition to the drive control of the digital recording unit 20, the above-described drive control of the analog recording unit 10 (for example, The control of each part constituting the recorder 1 such as the control of the recording unit 11b and the control of the paper feed mechanism 12 is performed.

  The setting unit 24 is configured with various hardware keys such as a setting key, up / down / left / right keys, and input devices such as a rotary knob. When a user performs a predetermined operation when performing various settings, an operation signal based on the setting content is received. It is output to the control unit 23.

When the position input device is mounted on the display unit 21 and has a touch panel function, the touch panel function may be used as the setting unit 24 instead of the hardware keys such as the operation keys described above.

  As described above, the recorder 1 of the present embodiment described above is provided with the window 2a on the door 2 so that the recording state in the analog recording unit 10 and the paper feed state of the chart paper can be visually recognized from the outside. Therefore, the recording state of the recording means 11 in the analog recording unit 10 without opening the door 2 (that is, the waveform drawing or hitting state of the recording member 11b with respect to the chart paper) and the chart paper by the paper feeding mechanism 12 The paper feed state can be confirmed in real time. Therefore, even when chart paper is jammed, out of paper, or malfunctions due to the recording means 11 occur during recording of measurement data, it is possible to respond quickly.
