Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heat-sensitive recording device, and particularly to a heat-sensitive recording device of a type in which a heat-sensitive recording paper is inserted between a heat-generating pen and a pressure receiving body to perform color recording. .

[Conventional technology]

The color recording action in a heat-sensitive recording device is carried out by the transfer of heat between the heat-sensitive recording pen and the heat-sensitive recording paper, which are in pressure contact with each other, so that the color-forming layer contained in the heat-sensitive recording paper is thermally melted. Therefore, when factors that affect the transfer of heat between the two are added, the recording line becomes thicker, thinner, or broken, resulting in unclear recording.

Conventionally, a plastic surface has been used as a support for thermal recording paper for a thermal recording pen, and this support has been rotated as the recording paper moves.

[Problem that the invention seeks to solve]

However, such a device that rotates the support in conjunction with the movement of the recording paper requires a mechanism for continuous rotation, resulting in a complicated configuration.

SUMMARY OF THE INVENTION An object of the present invention is to provide a thermal recording device that can maintain uniform color recording density with a simple configuration.

[Means for solving problems]

The feature of the present invention is that the pressure receiving body is configured in a semi-fixed manner so that the position where the heat-sensitive recording pen contacts the pressure receiving body can be moved, and the position where the heat-sensitive recording pen contacts the pressure receiving body is moved by a predetermined amount. The reason is that the pressure receiving body moving handle is attached to the end of the pressure receiving body.

[Effect]

As mentioned above, since the pressure receptor is semi-fixed, the pressure receptor is stationary during color recording, that is, when the thermal recording pen comes into contact with it, so the color recording density can be made uniform, and the pressure receptor When pressure marks are formed on the surface, the pressure-receiving surface of the pressure-receiving member can be made a new surface by moving the pressure-receiving body by a predetermined amount using the moving handle. It is possible to provide a heat-sensitive recording device that can maintain a uniform color recording density with a simple configuration.

〔Example〕

The figure is a perspective view showing an embodiment of the present invention, and shows a recording section of a direct recording type motion recording device.

The pen unit of this device includes a tip heating pen group 1 for intermittent linear recording having a plurality of tip blocks, and a single thermosensitive recording stick pen 2 for analog recording. A recording device with such a configuration is
For example, it is suitable for simultaneously recording the operating state of a device such as an elevator that is controlled using a large number of relays. In the figure, the pressure receiving body 7 is for receiving the thermosensitive recording pens 1 and 2, and is in the form of a roll, and its length is longer than the paper width of the thermosensitive recording paper 4. The thermal recording paper 4 is fed by a recording paper feed roll 5.

The thermal recording tip heating pen 1 and the thermal recording rod heating pen 2 are in pressure contact with a roll-shaped pressure receiving body 7 via a thermal recording paper 4. The thermal recording tip pen 2 is always maintained at a constant temperature and continuously moves and records on the thermal recording paper according to the signal, but the thermal recording tip heating pen 1 is at a fixed position and changes depending on the presence or absence of a signal. The temperature changes instantaneously in response, and an intermittent straight line is recorded on the thermosensitive recording paper. The heat-sensitive recording tip heating pen 1 has a very small heat capacity of about 3 milliseconds in order to improve responsiveness. Therefore, it is desirable to keep the factors that affect the exchange of heat between the heat-sensitive recording tip 1 and the heat-sensitive recording paper 4 as low as possible. Therefore, in this embodiment, the surface of the pressure receiving body 7 of the heat-sensitive recording pen is made of a polymeric material, for example, a fluorocarbon resin layer, so that the surface of the pressure-receiving body 7 of the heat-sensitive recording pen is extremely clear without reducing the responsiveness of the tip heating pen for heat-sensitive recording. It was confirmed that accurate records could be obtained.

The roll-type pressure-receiving body 7 is semi-fixed, and if pressure marks are generated to the extent that the thermal recording becomes unclear after remaining stationary for a long time, the roll-type pressure-receiving body 7 can be rotated by a predetermined angle using the handle 8. The new surface is used as the pressure receiving surface.

〔Effect of the invention〕

As described above, according to the present invention, by making the pressure receiving body semi-fixed, it remains stationary during recording, and when a pressure mark is formed on the surface of the pressure receiving body, the position of the pressure receiving body in contact with the recording pen is adjusted. Since the pressure-receiving surface can be moved and the pressure-receiving surface becomes a new surface, the clarity of the thermal recording is not impaired due to the presence of pressure marks, and the color recording density can be maintained uniformly with a simple configuration. equipment can be provided.
