Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer capable of printing based on predetermined input, and is particularly used for measurement or control.
The present invention relates to a printer that is capable of good recording even in an environment containing a large amount of water, oil, dust, etc., and that allows easy management of the recording.

[Background technology and its problems]

In recent years, electrical measurement and control has rapidly progressed, and printers that can print on recording paper based on predetermined input are used as a means to record the progress of work and measurement results, improving work efficiency and improving work efficiency. Rationalization is becoming a widespread practice.

For example, a measuring device disclosed in Japanese Patent Application No. 59-33574 filed by the present applicant is equipped with a digital electronic display and a printer as a recording device, making it possible to print and record measured values. This eliminates the need to manually copy and record the measured values displayed on the electronic display, resulting in a significant improvement in work efficiency.

By the way, in such printers, the printed recording paper that is printed and sent out from the delivery port is not subjected to any particular processing such as determining the sending direction or grouping it together, and the printed recording paper is sent out from the printing surface side. When the paper was sent out unwrapped, it was sometimes turned upside down and the printed content could not be confirmed.

In addition, if the paper is sent out continuously, the printed recording paper may be folded up in a messy manner or may even hang down to the floor, and may come into contact with other devices and become soiled or damaged. In addition, it was difficult to handle the printed recording paper, which caused problems when moving it.

One possible solution to this problem is to cut the sent printed recording paper into short pieces of appropriate length, but if a group of data is large, the order of a series of records may become unclear. , lost it, etc.
It becomes difficult to organize records. For this reason, it is possible to manually correct and organize the paper without cutting the printed recording paper, but this may interrupt work such as measurement and lose the advantage of improved workability. There was a drawback that the recording paper was stained by water, oil, etc. that got on the hands during work.

Furthermore, printers generally need to be provided with an opening such as an outlet for sending out printed recording paper, but there are various environments in which tasks such as measurement and control are performed, and printers used in such environments , there is a risk that water, oil, dust, etc. may enter through the opening and damage the internal equipment, and the printed recording paper that is printed and sent outside through the opening is particularly susceptible to water, oil, etc. Therefore, there is a need for a means to protect the internal device and the recording paper before or after printing from such surrounding water, oil, dust, etc.

[Purpose of the invention]

The purpose of the present invention is to enable easy confirmation of the print results printed on recording paper based on predetermined input, protect the recording paper and internal devices from surrounding water, oil, dust, etc., and provide a constant amount of recording paper. The object of the present invention is to provide a printer that can accommodate a regular roll of paper.

[Means and actions for solving problems]

In the present invention, a printer capable of printing on recording paper based on a predetermined input has an internal printing device that supports a roll of recording paper in a manner that projects upward and takes in the recording paper and prints. a device main body, which is provided with an output port for sending out the recording paper printed by this printing device; and a cover made of a transparent material that collectively covers the protruding portion of the recording paper supported by the device main body.

The cover, when attached to the device main body, has a shape that surrounds the arc-shaped portion of the recording paper along substantially the circumference of the arc-shaped portion of the recording paper when supported by the device main body, and an arc-shaped portion that guides and feeds the printed recording paper sent out from the outlet into a space that cooperates with the arc-shaped portion of the recording paper to form sections in the same direction as the rotational direction of the recording paper accompanying printing. and a storage space for accommodating a certain amount of printed recording paper guided into the space defined by the arc-shaped portion.

In addition, a space defined by an arc-shaped portion of the recording paper supported by the device main body and a circular arc-shaped portion of the cover is partitioned into the storage space of the cover or in the vicinity thereof, so that the space from the delivery port of the device main body is partitioned. A guide member is provided to guide the printed recording paper sent out to the storage space.

When a predetermined input is given to such a printer to print, the recording paper is printed with characters etc. representing the content based on the predetermined input, and is treated as a printed recording paper.
The paper is sent out of the device body from the delivery port, guided into the cover by its arc-shaped part, passed through the space (guiding space) between the recording paper and the periphery of the protruding part, and is passed between this space. By being sent along the recording paper in the direction of rotation associated with printing, it is driven in contact with the circumferential surface of the recording paper, and is smoothly sent toward the storage space. During this time, the printed recording paper is sent to the storage space with the printed side facing out inside the arc-shaped part of the cover without turning over, making it easy to check the printing results etc. through the cover made of transparent material. be able to. In addition, the recording paper and the output port are protected by a cover and are not exposed to the outside, so the recording paper and devices inside the main unit are protected from water and water from the surrounding area.
Prevents contamination with oil, dust, etc. Furthermore, the printed recording paper that is fed along the circumferential surface of the recording paper inside the arc-shaped part of the cover is smoothly guided by the guide member to the storage space provided in the cover, and can be taken out all at once. A predetermined amount of paper is stored neatly in a state where it is possible, which prevents it from being sent out in a disorderly manner and becoming dirty or difficult to handle, making it easier to manage. The present invention aims to achieve the above object.
