Description

DETAILED DESCRIPTION OF THE INVENTION 1. Technical Field of the Invention The present invention relates to a recorder, and particularly to a recorder using folded recording paper.

2. Prior art and its problems This type of recorder makes it easier to observe recorded areas than roll-type recording paper, and it can be easily cut from the perforations formed in the folded part, making it easier to organize materials. It has the advantage of being simple.

However, in a recorder using an ink pen, for example, ink may smear at the perforations of the folded recording paper. In addition, for example, in a recorder using a heat-sensitive head, when the heating element located in the perforation hole generates heat,
The generated heat cannot be dissipated and the heating element is damaged. For example, at a paper feed speed of 20 mm/H, it takes 18 seconds for a perforation of 0.1 mm to pass through the hole, and a thermal head that heats once every several milliseconds during this time will heat the paper about 2000 times. Therefore, if this generated heat is not dissipated, there is a risk that the heating element will be damaged.

3. Object of the Invention The present invention focuses on the fact that the above-mentioned problem can be solved by detecting the folded portion, and provides a recorder equipped with a position detection mechanism for detecting the folded position.

4. Structure of the Invention The present invention is configured to include a position detection mechanism for detecting the folding position of the folded recording paper so that the folding position can be accurately detected.

5 Embodiments of the Invention The following describes one embodiment of the present invention in Figures 1 to 4.
This will be explained with reference to the figures.

FIG. 1 shows a schematic diagram of a thermal recorder using folded recording paper. Reference numeral 10 denotes folded recording paper, which is conveyed in the direction of the arrow by conveyance rollers 11, 12, tension roller 13, and drive rollers 14, 15 from an unrecorded paper storage chamber (not shown). A thermal head 16 has a plurality of heating elements 17 arranged in parallel in the width direction of the recording paper 10. These heating elements 17 are caused to generate heat by a head driving section which will be described later. Moreover, this heat-sensitive head 16 is
It is pressed onto the recording paper 10 with a predetermined pressure.

Further, the recording paper 10 is provided with perforations 18 at its folded portion. As shown in FIG. 2, a marker 20 is attached to a portion of this perforation 18 located at the end of the recording paper 10.
Incidentally, instead of this marker 20, a through hole 30 as shown in FIG. 3 may be opened.

Further, as shown in FIG. 1, a position detection mechanism 40 for detecting the position of the perforation 18 is arranged at a position sandwiching the conveyance path of the marker 20 of the recording paper 10. This mechanism 40 includes, for example, a light source 41 and a light receiver 42, and detects changes in the amount of transmitted light depending on the presence or absence of the marker 20. The position of the position detection mechanism 40 is such that when the perforation 18 faces the heating element 17, another perforation 18 is detected.

Further, this position detection mechanism 40 is connected to an on/off circuit 45 connected between a power source 43 and a recording mechanism 44, as shown in FIG. This on/off circuit 45 receives a marker detection signal from the position detection mechanism 40 and connects a power source 43 and a recording mechanism 44.
It is a barrier between the two. In addition, the recording mechanism 4
Reference numeral 4 comprises a head driving section 46 and a thermal head 47, which receives input of information to be recorded (not shown) and causes a heating element 17 corresponding to the input signal to generate heat.

Note that even when the power source 43 is cut off by the on/off circuit 45, the information input is continuously inputted, so in some cases, this input signal may be temporarily stored and the power source 43 can be used as the recording mechanism 44.
When connected to the recording paper 10, the memory contents are transferred to the recording paper 10.
It also needs to be recorded above. In this case, the recording amount is accumulated every time a marker is detected, and the recording time and the actual input signal are different from each other.
The time discrepancy can be resolved by increasing the 0 feed speed faster than usual and recording in a short time.

With this configuration, when the perforation 18 portion of the folded recording paper 10 faces the heating element 17, the power supply to the head drive section is cut off and the heating element 17 does not generate heat, so that it does not generate heat as in the conventional case. There will be no accumulation of quantity.

In this embodiment, the power supply 43 is cut off by a signal from the position detection mechanism 40, but as shown in FIG. has the same effect. That is, the speed control section 5 between the feed speed setting section 52 of the motor 51 and the motor 51
3 is supplied with a signal from the position detection mechanism 40, and when the perforation 18 reaches the position facing the heating element 17, the speed is set to be faster than the normal recording paper feeding speed. According to this, if heating element 1
Even if 7 generates heat while facing the perforation 18, the amount of heat it accumulates does not increase because the facing time is extremely short.

Further, by utilizing the recording paper feed speed control of this embodiment, it is also possible to cut out unnecessary portions of recording, as shown in FIG. 6, for example. 60 is a marker, 61 is a scale line, and 62 is a recording line.

Further, in an ink pen type recorder, although not shown, if the pen is separated from the recording paper 10 based on the perforation 18 detection signal from the position detection mechanism 40, the same effect as in the previous embodiment can be obtained.

Further, although the ink pen type and thermal type are used in the explanation, it is of course possible to use other types such as electrostatic recording type.

6. Effects of the Invention Since the present invention is configured as described above, it is possible to accurately detect when the perforation position of the folded recording paper reaches the recorded portion. Therefore, good recording can be obtained by using this signal.
