Abstract

PURPOSE:To match automatically the position of time printing by comparing the position of a specifically determined chart and the present time and starting recording in such a way that the time is printed in the prescribed position from the reference scale of the chart. CONSTITUTION:A chart 10 provided with holes 12 in the positions of a main scale 11 which is a reference scale is fed stepwise in the direction A by a feeding means 20. A detecting part 30 is constituted of a photosensor 31 which generates the signal corresponding to the presence or absence of the hole 12 and an edge detector 32 which generates a signal when the end of the hole 12 is detected. The feed step of the chart 10 is counted with a step counter 40 and the contents thereof is transferred by the signal of the detector 32 to a step measuring means 60. The feed rate of the chart for positioning the time printing position is determined in a control part 70 from the signals of a means 60 for counting the number of the steps required for feeding the chart 10 at the spacing between the scales 11, a counter 40 and a clock 50 and the feed of the chart 10 is controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording device having a function of printing time on a chart.

In recording devices that have the function of printing the time, the time stamp is printed as needed, or the time stamp is sent in a fixed direction. The chart is provided with reference scales such as grain, kilometer, etc. along the feeding direction. If the time stamp is written without regard to the grain of the chart, it becomes difficult to read the record at the time the time stamp is written based on the grain of the chart.

For this reason, conventionally, in such a recording device, for example, the recording pen tip comes to the skin mark or kilometer position at a specified time, and the chart is manually printed so that the specified time (00 minutes) is printed at this position. The one that made me adjust the recording start position broke.

However, in such a recording device, the present invention was made to eliminate the above-mentioned problems, and the recording device in which the position of the time stamp on the chart is automatically aligned. The purpose is to provide.

A detailed explanation will be given below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a recording apparatus according to the present invention.

In FIG. 1, 10 is a chart, 20 is a chart feeding means, 30 is a detection section, 40 is a step counter, 50 is a clock, 60 is a step measuring means, and 70 is a control section.

The chart 10 has predetermined positions relative to the reference scale.

The chart feeding means 20 feeds the chart 10 in a stepwise manner in the A direction in response to a chart feeding signal from the control section 70.

In the detection unit 30, 31 is a photosensor, and the hole 1
2 is placed in the position where it passes, and corresponds to the presence or absence of a hole. Generates N10Fy signal. ? Reference numeral I2 denotes an edge detector, which generates an edge signal when the photosensor 51 detects the edge of the hole 12.

The step counter 40 receives a chart feed signal generated by the control unit 70 and increases the count each time the chart 10 is fed by one step, and when an edge detection signal is sent from the edge detector 32, the step counter 40 measures the step count. Means 60
It will be moved to and cleared.

Clock 50 generates a signal according to time.

The step measuring means 60 measures the number of steps required to advance the chart 10 by coarse intervals. Let this number of steps be X.

0 The control section 70 includes a calculation means 71 and a chart feed control section 72.
Consisting of The calculating means 71 calculates the amount of chart feeding for positioning the time stamp based on signals from the step counter 40, the clock 50, and the step measuring means 60. The chart feed control unit 72 receives a signal corresponding to the chart feed needle from the calculation means 71 and moves the chart 1
Controls the feed of 0.

Next, the operation of such a recording apparatus will be explained.

As an example, a case will be described in which the coarse grain interval is 20 mm and the chart feeding speed is 20 rru1i/h. FIG. 2 is an explanatory diagram of positioning of time stamps on such a chart. In FIG. 2, the same parts as in FIG. 1 are given the same reference numerals. The same applies to the figures below.

If the distance between the position of the pen tip of the recording pen and the grain 11 when the detection unit 30 detects the hole end of the hole 12 is W (mm), then the number of steps required to send the chart by this distance W x 8 becomes K as follows.

x8 20 20 The chart 10 stops after the detection unit SO detects the hole end of the hole 12 after being loaded. The position where the hole end was detected is B
Here, the count of the step counter 40 is reset. Let C be the position where the chart 10 has stopped, and let Xp be the 400 count of the step counter at this position. Further, if the minute digit at the time of stopping is tp, the number of steps from the grain is χ2oxtP/60, that is, the number of steps from the hole end is 00 minutes. If you have a chart that does not work like this, that is, x

FK and then K as follows.

tp F 2o 60S P On the other hand, if the actual time t is later than the time corresponding to the position of C, that is, X 20 × (Lp/60)
+ In the case of Xs<Xp, the forward view for time adjustment is as follows with the number of steps ~.

mp = “2 (1” (b o “1)” X s
-X p printing position After [I M * bl is performed in this way,
Recording begins.

The feed amount for time adjustment in the former case and the latter case corresponds to t and t2.

According to such a recording device, the following effects can be obtained.

Since the control unit 70 adjusts the position of the time stamp based on the signals from the step counter 40, the clock 50, and the step measuring means 60, the position of the time stamp can be automatically adjusted.

Therefore, for example, time 0 is displayed on coarse mesh 11 of chart 10.
Recording and time stamping at 0 minutes can be performed automatically.

FIG. 3 is a block diagram of another embodiment of the recording apparatus according to the present invention.

This recording device uses a standard chart provided with a tin rocket hole 14 into which a sprocket pawl is engaged. A plurality of sprocket holes, for example, three sprocket holes, are provided at equal intervals in the parent hole of the chart 10. Note that a plurality of other tin rocket holes may be provided in the main day.

Further, the detector 30 is provided with a zone counter 33. The zone counter 35 increases the count each time the photosensor 31 detects the tin rocket hole 14, and is forced to OK when the count reaches 5. From this, the count is 0.1.2° (1, 1, 2...
...to return.

Next, the operation of such a recording apparatus will be explained.

A case will be described in which the parent day interval and the chart feed rate are the same as those of the recording apparatus shown in FIG. 1. FIG. 4 is an explanatory diagram of positioning of time stamps on the chart.

In this chart, five sprocket holes 14 are open on the main day. From this, it is divided into three zones D, E, and F using the sprocket hole 14 as a delimiter. Then, the chart is loaded by making a coarse cut at the 9th fold of the chart. At the end of the chart, the count of the zone counter 33 is set to 1kO. Therefore, the zone counter in D, E and F portions is 3! Each count of I is 0.
1 and 2.

1t(
Position G) Only at K, the contents of the step counter 40 are transferred to the step measuring means 60 and cleared.

Therefore, the count of the step counter 40 is cleared every parent day.

In this manner, the zone counter 33 identifies the sprocket hole detected last in the parent day. .

In such a recording device, after the chart 10 is loaded, it is detected by the photosensor 5 by identification of the zone color/receiver 33.
1 detects the hole end at position G and then stops. This stop position corresponds to position C. Thereafter, after the time is set in the same manner as in the case of FIG. 2, recording is started.

According to such a recording apparatus, in addition to the effects obtained by the recording apparatus shown in FIG. 1, the following effects can be obtained.

That is, the zone counter 53 identifies a plurality of sprocket holes provided in a parent day, and clears the count of the step counter 40 for each parent day. For this reason, a standard chart in which a plurality of sprocket holes are provided in the main part can be used as the chart.

In addition, in the example, the chart feeding speed is 20 rrrn
/h and the interval between dates is 20 mm, but the chart feeding speed and interval between dates may be set to other values.

Furthermore, in the embodiment, a case has been described in which the set time is set roughly, but the set time is not limited to this, and the set time may be set roughly.

Further, in the embodiment, a case has been described in which a regular 60-minute scheduled time is printed, but any designated time may be printed on a coarser scale.

Further, in the embodiment shown in FIG. 1, a case has been described in which the hole 12 is provided at the position of the coarse mesh 11, but the hole 12 is not limited to this, and the hole 12 may be provided at a position having a predetermined relationship with respect to the reference scale.
