DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment. FIG. 5 is a cross-sectional view of a recording paper used in the present invention. The recording paper is formed by applying an adhesive layer 2 to at least one surface of a base paper 1. In the adhesive layer, microcapsules 3 containing an adhesive and a binder 4 for linking them
Are mixed and applied to the base paper. When this recording paper is heated, the microcapsules are broken, and the adhesive in the microcapsules flows out to the application surface to form an adhesive portion.
An example of such a recording sheet is disclosed in Japanese Patent Application Laid-Open No. 2-292380.
Discloses a further improved recording paper configuration.

In the recording paper having such a configuration, for example, the degree of destruction of the microcapsules differs depending on the amount of heating, so that a difference generally occurs in the adhesive strength.

FIG. 1 is a schematic diagram showing the configuration of an embodiment of the printing apparatus of the present invention. 5a and 5b are recording papers 20 respectively.
Are a feed roller and an auxiliary roller that form a first recording paper feed mechanism 5 that conveys the print head 7 to a printing unit in which the print head 7 is disposed. In the printing section, a platen 8 is arranged in addition to the print head 7. Reference numeral 9 denotes a recording paper cutter for cutting the recording paper to a predetermined length. The recording paper cutter cuts the recording paper after printing, and has a desired size to be attached to an article by utilizing the adhesiveness of the recording paper. 6
Reference numerals a and 6b denote a paper feed roller and an auxiliary roller of the second recording paper feed mechanism 6 for conveying the cut recording paper, respectively. Reference numeral 10 denotes a heating roller, which is a kind of a heating member, and is a heating member for heating the back surface of the recording paper 20, in which a heating element such as a nichrome wire for heating is arranged. Reference numeral 11 denotes an auxiliary roller disposed to face the heating roller.

The surface of the heating roller 10 is subjected to a Teflon coating process or a silicon coating process, so that even a recording sheet having an adhesive floating on the surface can be properly conveyed. Similarly, the surface of the auxiliary roller on the adhesive layer side of the second recording paper feed mechanism is coated with a material such as Teflon coat or silicon coat which does not accept an adhesive. The heating roller 10 has a lifting mechanism (not shown) having a configuration capable of coming and going in the direction of arrow A with respect to the auxiliary roller 11 installed at a position facing the recording paper conveyance path by a plunger or the like. .

Reference numeral 12 denotes a reflection type recording paper sensor.
It detects the end of the cut recording paper.

The first and second recording paper feeding mechanisms are connected to a motor (not shown), which is a common driving source, and are configured to be independently operable by a mechanism such as a clutch. In the present application, a stepping motor is used as the motor in order to easily detect the moving amount of the recording paper.
Further, when the recording paper is driven at the same time, the recording paper operates in synchronization and the recording paper is fed properly.

Although various types of print heads are used for the print head 7, an ink jet head is preferable in consideration of noise and the like. In addition, since the recording paper is heated by the heating roller 10, even if a large amount of ink such as image printing is ejected and the recording paper becomes wet due to the printing of the ink jet head, drying is promoted and the ink may reach the hand. The advantage is that there is no such thing.

The recording paper cutter 9 is provided with a power source (not shown).
And the recording paper can be automatically cut by a control signal. Further, since the arrangement position is located upstream of the heating member 10 in the recording paper conveyance direction, the recording paper can be cut before the recording paper has adhesiveness, and the material of the cutter blade is subjected to Teflon coating or the like. It is not necessary and can be realized at low cost.

FIG. 2 is a schematic diagram showing a method for holding printed recording paper. The cut recording paper 20
Since the adhesive is exposed on the back surface and is in an applied state that has appeared on the surface, it cannot be cut off, laminated, or cut off. Therefore, in the present invention, a method for effectively holding the separated recording paper pieces will be described below. The end of the cut recording paper is detected by the sensor 12. The length L of the conveyance path from the sensor 12 in the conveyance path of the recording paper to the approximate center of the roller of the second recording paper feeding mechanism is specified in advance by the configuration of the mechanism section. Since the relationship between the paper feed amount and the number of steps of a driving step motor (not shown) connected thereto is set in advance, the moving position of the recording paper after cutting is determined by this number of steps. Can be easily determined in a processing device incorporating the.

By using this feature, the recording paper is held by the second recording paper feed mechanism, and the recording paper is easily moved to a position where the recording paper can be easily taken out if the operator pulls lightly to take out the recording paper. To stop. A recording paper sensor 13 detects whether the recording paper has been taken out.

FIG. 3 is a schematic diagram of a control device of a printing apparatus according to the present invention. Reference numeral 50 denotes a central processing unit that controls the entire apparatus. 51 is a head control unit for controlling the print head 7, 52 is a motor control unit for operating a motor 60 for driving the recording paper feeder, 53 is a heating control unit for the heating member 10, and 54 is a temperature for detecting the temperature of the heating member. Each of the detection means is shown. A temperature sensor 63 using a thermistor or the like is connected to the temperature detecting means 54. The thermistor 64 is a temperature sensor that is an ambient temperature detector.
5 is an ambient temperature detecting means. 56 is a recording paper sensor 1
2 shows recording paper detecting means connected to 2 and 13. 5
Reference numeral 9 denotes cutter control means for operating the cutter 9. 7
Reference numeral 1 denotes a lifting mechanism control unit that controls the lifting mechanism 14 of the heating roller 10.

The heating roller 10 of the heating member is controlled so as to have an optimum temperature so that the temperature of the heating member does not change so much even when the ambient temperature changes. At this time, electric energy to the heating member is controlled based on a signal from a temperature sensor attached to the heating roller 10. Generally, the same temperature may be controlled based on the output of the temperature sensor 63 of the heating roller. However, considering that the printing apparatus is used in an environment such as an outdoor environment, when the recording paper is left at 0 ° C. In some cases, simply controlling the temperature of the heating roller is not sufficient.In this case, the ambient temperature is corrected, and when the ambient temperature is low, the applied energy is slightly increased to increase the set temperature, and when the ambient temperature is high, It is better to suppress the applied energy and set it lower. By controlling in this way, it is possible to control the temperature to an optimum.

The motor 60 includes electromagnetic clutches 61 and 62
Are attached, and clutch control means 57, 58 are respectively provided.
Is controlled by With this configuration, the first and second recording paper feeding mechanisms 5 and 6 can operate synchronously or independently of each other.

FIG. 4 is a flowchart showing a specific processing method of the processing for holding the recording paper.

In step 100, the first and second recording paper feed mechanisms 5, 6 are operated in synchronization to execute a printing process. In step 101, when printing is completed, the movement of the recording paper is stopped, and the cutter is operated to cut the recording paper. The recording paper cut in Steps 102 and 103 is conveyed by operating the second recording paper feeding mechanism 6 until the end of the recording paper is detected. After the end of the recording paper is detected, the conveyance of the predetermined amount L is performed in Step 104. Run with As a result, a series of recording operations is once completed, and the recording paper is held in the state shown in FIG. 3 (step 105).

Thereafter, in preparation for the next printing, it is detected whether or not the recording paper has been taken out of the printing apparatus by using the recording paper sensor 13 (step 106). In step 107, it is checked whether or not the recording paper is continued.
If the printing of 0 is not continued, the printing ends.

Since the surface of the roller on the adhesive layer side of the recording paper 20 of the second recording paper feed mechanism 6 is subjected to processing such as Teflon coating or silicon coating, the recording paper is lightly nipped by the roller. Even if it is left in a state, it does not stick to the rollers, and can be taken out of the device by lightly pulling it by an operator.

A processing device for executing these flowcharts is represented by a block diagram shown in FIG.
A program is stored in a ROM by a circuit board having a RAM or the like.
This can be realized by storing it in These constitute a control means for executing the above flowchart.

The above-mentioned heating roller 10 is configured so as to be liftable so as to come in contact with and separate from the auxiliary roller 11 in the direction of the recording paper conveyance path, and heats the heating roller as needed. If the recording paper is plain paper, the heating itself may be stopped and the power may be turned off. In addition, although a member to be heated is a roller-shaped member as an example, a heating member in which a plurality of heating elements are arranged like a thermal head used as a print head,
It is also possible to vary the adhesive force by controlling the heating amount. In such a type, it is not necessary to prepare the heating member in a state where the heating member is constantly overheated, and the heating can be performed in response to a signal for heating the recording paper, so that there is an advantage that power consumption can be reduced.

For controlling the adhesive force, the heating amount can be controlled by lifting the above-mentioned heating roller. With this configuration, it is possible to obtain an adhesive force suitable for the purpose of bonding. In this case, a switch or the like for setting the adhesive strength is installed in the control device, and based on the set value,
The amount of heating or the temperature of the heating roller is controlled.

Further, a temperature sensor is installed in the recording apparatus so that a difference in adhesive strength does not occur due to a difference in room temperature or the like, and the CPU uses the detected value to perform arithmetic processing to control the amount of heat generated by the heating roller. By doing so, it is possible to obtain an adhesive force independent of room temperature or environmental temperature.
These controls can be easily realized by installing a temperature sensor on the circuit board, installing a temperature sensor on the heating member in the same way, and incorporating a control program based on these detected values in the ROM. It is.

In this embodiment, an example in which the adhesive is applied to the back surface of the recording paper has been described. However, a type in which the adhesive is raised on the recording surface may be required depending on the application. In this case, What is necessary is just to arrange a heating member on the recording surface side.

Further, the configuration of the heating member has been described in the form of directly applying thermal energy. However, it is also possible to break the microcapsules by irradiating a laser beam or the like and release the adhesive. Although the recording paper has been described with an example in which the adhesive is encapsulated in the microcapsules, the recording paper may be of a type in which the adhesiveness is revealed by heating or a chemical change by laser light.

[0033]

As described above, according to the present invention, an adhesive layer is formed at the same time as printing using a recording paper coated with a material from which an adhesive floats when heated on one side of the recording paper. It is possible to provide a printing device that can be immediately attached to an article after printing.

Further, by controlling the amount of heating of the recording paper by the heating member, it is possible to obtain the necessary adhesive force.

Further, by holding the recording paper in the recording paper feeder, it is possible to provide a configuration in which the recording paper to which the adhesive has been applied can be easily held by an operator.
