Description

[Detailed explanation of the invention] (a) Industrial application field This invention is connected to a spectrophotometer measuring instrument.
This invention relates to a recorder that prints and records waveform data measured by a measuring device on a roll-shaped recorder.

(B) Conventional technology A conventional recorder has a thermal head placed in the center of the instrument body, and is equipped with a roll of recording paper and paper feeding means (a platen roller equipped with a motor) corresponding to this thermal head. The recording paper is also configured to be fed to a thermal head (not shown).

This recorder is connected to a measuring device such as a spectrophotometer, and records the waveform data measured by the measuring device on a recording paper using a thermal head. The operator (data manager) confirms whether the control status of the object to be measured is correct or not based on the printed waveform data on the recording paper that is sequentially and continuously sent out from the recorder.

(c) Problems to be solved by the invention In conventional recorders, a long roll of recording paper is moved by a paper feeding means, and measurement data is printed and recorded during this movement. Therefore, a long recording paper on which a plurality of measurement waveform data are continuously recorded is sent out from the instrument body.

For this reason, when the operator (data manager) stores the long recording paper that is continuously printed and recorded for each measurement and sent out from the recorder, the operator (data manager) usually prints on the long recording paper. Fold or cut with a chart cutter according to the measurement data. Thereafter, holes are punched in the folded or cut recording paper using a separately prepared punch (file hole puncher), and the paper is bound into a file and stored.

However, the work of punching holes for each piece of measurement data on this long recording paper is not only cumbersome, but also has the disadvantage of requiring time and effort to store and organize the recording paper.

This idea solves the above problems,
To provide a recorder capable of automatically opening a file punch hole at a desired position for recording paper that is continuously sent out, and facilitating the storage work of recording paper.

(d) Means and action for solving the problem In order to achieve this purpose, the recorder of this invention has the following configuration.

The recorder is a recorder that feeds a roll of recording paper in correspondence with a thermal head using a paper feeding means to print and record data on the recording paper. A hole punching means for forming a punch hole is provided which advances and retreats with a spring in a direction perpendicular to the paper feed means, and the hole punching means is connected to the punching means and is biased by a spring in response to driving and stopping of the paper feeding means. It is configured to include a hole punching drive means that moves the hole forward and backward relative to the paper.

In a recorder having such a configuration, the recording paper advancing side of the paper feeding means (motorized platen roller),
That is, a hole punching means for forming punch holes and a punching drive means for driving the punching means are provided near the paper feed outlet of the instrument body case.

The hole punching means is, for example, a flat plate having a hole punching shaft with a blade at its tip protrudingly provided, and tiltable arms are integrally fixed to both ends of the flat plate.
One end of a tension spring is fixed to one end of this arm, and the arm is always biased toward the proximal end of the tension spring. In this state, the arm is tilted by a spring, and the tip of the opening shaft is set to penetrate through the recording paper. In other words, the setting is such that punch holes are formed in the recording paper. In addition, an electromagnetic solenoid (drilling driving means) is connected to the other end of the arm, and this electromagnetic solenoid is energized when the paper feeding means (platen roller) is driven, that is, when paper is fed, and the arm moves against the spring. is set so as to pull the hole in the opposite direction and move the punching shaft back in a direction perpendicular to the recording paper. As a result, the recording paper is transported (paper fed) outward from the paper delivery port portion while being printed without the perforation shaft being an obstacle. This electromagnetic solenoid is set to stop energizing, for example, when the measuring device finishes printing and recording one measurement data and the paper feeding mechanism stops. Therefore, when the current supply is stopped, the hole punching means (hole punch shaft) is tilted back to its original position by the tension spring, and the hole punch shaft penetrates the recording paper in a direction perpendicular to the recording paper, punching a hole in the recording paper. Open. Therefore, a hole is punched in the recording paper every time one measurement is completed, that is, before the next subsequent measurement data is printed. Here, by cutting the long recording paper sent out from the instrument body with, for example, a chart cutter, using the punch holes opened for each measurement data as a reference, the printed records for each measurement can be easily bound into a file. Easy to prepare and store.

(E) Embodiment FIG. 1 is a sectional view showing a recorder according to this invention.

As is well known, in the recorder, a thermal head 2 is disposed at the center of an instrument body case 1, and a roll of recording paper 3 and paper feeding means 4 are disposed below the thermal head 2. The paper feeding means 4 includes a platen roller 41 equipped with a feeding protrusion (not shown) that engages with a feeding hole of the recording paper 3, and a motor 42 connected to the platen roller 41 via a drive belt 43. It is composed of. The meter body 1 is provided with a recording paper delivery port 11 corresponding to the advancing side of the recording paper 3, and a delivery guide plate 5 for the recording paper 3 corresponding to the recording paper delivery port 11 is opened.
5a are arranged in the vertical direction.

A feature of this invention is that a punch hole opening means is provided corresponding to the recording paper delivery port portion (recording paper delivery guide plates 5, 5a) 11.

The punch hole opening means includes a recording paper feeding guide plate 5,
5a, a drilling means 6, and a drilling driving means 7.

As shown in FIG.
Two through holes 52 are opened at a constant interval in the plane. The pair of through holes 52, 52 are set to correspond to the binding string spacing of normal files. Further, a receiving blade portion 5 is provided on the inner peripheral edge of the through hole 52.
2a is provided. This pair of delivery guide plates 5,
5a are disposed facing each other in the vertical direction, and the recording paper 3 is transferred between them.

The hole punching means 6 has a Japanese hole punch shaft 62 integrally protruding from the tip (upper surface) of a rectangular flat plate portion 61, which corresponds to the through hole 52 of the delivery guide plates 5, 5a. At the tip of this drilling shaft 62, a blade portion 62a having an inclined surface shape is provided. Furthermore, the flat plate part 6
1 is provided with bending arms 63 at both ends thereof. This bending arm 63 consists of a hole-opening side arm part 63a and a mounting side arm part 63b, both arm parts 63a and 63b are pivotally connected via a pivot 64 and are fixed integrally so as to be tiltable. . One end of this mounting side arm portion 63b is attached to the fixing piece 12 at the lower end of the instrument body case 1 via a tension spring 65 (see FIG. 1). That is, one end of the tension spring 65 is fixed to the mounting side arm part 63b, and the other end is fixed to the fixed piece 12, so that the mounting side arm part 63b is always urged toward the fixed piece 12 side. In this state, the tip of the drilling shaft 62 (blade portion 62
a) is the through hole 52 of the delivery guide plate 5, 5a.
It is set so as to penetrate through the recording paper 3 and punch holes in the recording paper 3 (see FIG. 3). Further, an electromagnetic solenoid (drilling drive means) 7 is connected and fixed to the other end of the mounting side arm portion 63b (on the opposite side to the tension spring 65). This electromagnetic solenoid 7 is electrically connected to the motor 42 of the platen roller 41, and is set to be energized (turned on) when the motor 42 is driven (paper feeding state) and turned off when the motor 42 stops. . When the electromagnetic solenoid 7 is energized, the mounting arm 63b is pulled in the opposite direction against the tension spring 65, the drilling arm 63a is tilted about the pivot 64, and the drilling shaft 62 is attached to the recording paper 3. It is set to move backward in a direction perpendicular to the direction.

The driving setting of the electromagnetic solenoid 7 is such that, for example, when the measuring device finishes printing and recording one measurement data and the paper feed (motor 42) stops, the energization is stopped. Therefore, one measurement is printed and recorded, and each time the printing of this one measurement data is completed, that is, before the next subsequent measurement data is printed, a punch hole for a file is opened in the recording paper 3. is set to be

In addition, when implementing the operation, the drive setting of the electromagnetic solenoid is such that the power supply is stopped when the paper feed motor 42 stops, and the drive setting of the electromagnetic solenoid is determined according to a preset paper feed length, and the energization is stopped every predetermined length (for example, A4 length). It may also be set to open punch holes. In this case, the electromagnetic solenoid 7 is configured to be turned off when the paper has been fed by a length of A4, for example, with a feed amount determined from the predetermined number of pulses of the drive motor and the diameter of the platen roller 41, for example. Alternatively, by using a light emitting/receiving element (not shown),
The length of the recording paper 3 is detected by detecting the number of passages of the recording paper 3 through the feed holes, and the electromagnetic solenoid 7 is turned off. Alternatively, punch holes can be added to the recording paper 3 at intervals of a certain length.

In the recorder having such a configuration, when the power source (start switch) is turned on to print and record measurement data, the drive motor 42 and the electromagnetic solenoid 7 are energized. As a result, the recording paper 3
The paper is fed by the platen roller 41. In this state, the hole punching means 6 is retracted in a direction perpendicular to the recording paper 3. In other words, the electromagnetic solenoid 7 resists the tension spring 65 and
By pulling b, the hole-drilling part side arm part 63a is tilted using the pivot shaft 64 as a fulcrum. As a result, the drilling shaft 62 is positioned further below the delivery guide plate 5a. Therefore, in this state, the recording paper 3 is printed and recorded by the thermal head 2, and is sent out from between the opposing delivery guide plates 5, 5a through the delivery port 11 to the outside of the instrument body case 1.
Now, if one printing record of measurement data by the measuring device is completed, the paper feed motor 42 is turned off and paper feeding is stopped. At this time, power to the electromagnetic solenoid 7 is simultaneously stopped. As a result, the mounting side arm portion 63b returns to its original position by the urging force of the tension spring 65, and the hole opening side arm portion 63b
b is tilted upward via the pivot 64. Here, the leading edge portion 62a of the drilling shaft 62 is inserted into the corresponding through hole (receiving blade portion 52) of the delivery guide plates 5, 5a.
a) Punch a hole through the recording paper 3 through the hole 52 (see FIG. 3). Again, when the second measurement data is transmitted to the recorder, the paper feed motor 42 is driven and at the same time the electromagnetic solenoid 7 is driven.
Similar operations continue repeatedly. Thus, as shown in FIG. 4, for a long recording paper 3 on which a plurality of data 31 are continuously printed and recorded, a punch hole 32 is formed at the end of the recording paper 3 for each printed measurement data 31. will be opened automatically. In FIG. 4, the broken line 33 means a virtual cutting line. Therefore, the operator can easily bind the long recording paper 3 into a file by cutting the long recording paper 3 using a chart cutter or the like based on the punch holes 32.

In the embodiment, an example was shown in which the operator cuts the long recording paper 3 with a cutter as in the conventional case, but when carrying out the operation, in addition to the punch hole opening means 6, this bunch hole opening means is used. A linked automatic cutter means (not shown) is provided, and when one printing record of measurement data is completed, the automatic cutter adds, for example, a perforation line to the recording paper 3, and then punch holes 32 are opened. It may also be used as a configuration.

(f) Effects of the invention As described above, this invention is equipped with a punching means for punching holes in the recording paper and a punching drive means for driving the punching means in the instrument body case. Therefore, it is possible to automatically punch holes in the recording paper on which the measurement data is printed and then send it out.

Therefore, the troublesome work of punching holes in the recording paper by the operator using a separate punch for binding, as in the conventional art, is eliminated. In addition, by folding or cutting the long recording paper with multiple measurement data printed on it sent from the meter body case based on the punched holes, it is possible to easily file the recording paper for each measurement data. It has the excellent effect of achieving the purpose of the invention, such as making it easier to manage and store measurement data.
