Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a recorder, and more particularly to a recorder that improves the operability of a recording paper storage section when replacing recording paper.

<Conventional technology> The conventional technology will be described below with reference to the drawings.

FIG. 3 is a schematic sectional view of a recording paper storage section of a conventional recorder.

In the third part, the recording paper storage section 2 integrated with the sprocket 1 is configured to be rotatable as shown by the arrow F to a predetermined position using the rotation center fulcrum pin 3 in the lower part as a fulcrum (as shown by the two-dot chain line). is the rotational position of the recording paper storage section, etc. when rotated). The rotation center fulcrum pin 3 is fixed to a side plate (not shown in FIG. 3) of the recording paper storage section 2, and is attached to a bracket 4. One side of the bracket 4 is supported by being inserted into a fixing pin 5 fixed to the main body frame (not shown in FIG. 3). Then, press the recording paper storage section 2.
is lifted by a leaf spring 6 provided on the lower side of the bracket 4, and positioned and fixed by a pin guide 7 provided on the side plate of the recording paper storage section 2 and a positioning pin 8 fixed to the main body frame. In this way, the recording paper storage section 2 is positioned and fixed. Therefore, when the recording paper 9 stored in the recording paper storage section 2 moves on the sprocket 1, recording is performed with the pen 10 based on a predetermined input, and the recording paper 9 is transferred to the recording paper storage section 12 while being pressed by the roller 11. Recorded recording sheets 9 are accumulated.

<Problems to be solved by the invention> However, this conventional recorder has the following problems.

: In order to ensure the positioning of the recording paper storage section 2, it is necessary to increase the spring force of the leaf spring 6.
As a result, a large force is required when swinging the recording paper storage section 2.

: There is a risk that the recording paper storage section 2 may fall due to vibration or impact.

:The structure becomes complicated, resulting in high cost.

The present invention was developed in view of the problems of the conventional technology, and it facilitates the operation when replacing the recording paper and prevents the recording paper storage section from falling due to vibrations and shocks.
The purpose is to provide an inexpensive recorder with a simple structure.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the recorder of the present invention has a recording paper stored in a recording paper storage section that is integrated with a sprocket and rotates to a predetermined position. A recorder that records a predetermined record by moving above the main body frame G includes a rotation center shaft 30 that rotatably supports the recording paper storage section 20 with respect to the main body frame G, and a rotation center shaft 30 that rotatably supports the recording paper storage section 20 on the main body frame. A guide hole 20a formed in a shape that allows rotational guidance to a predetermined position, a rubber damper G _D removably disposed on the inner periphery of the guide hole, and one end of which fits movably within the rubber damper. A rotation guide pin K _P whose other end is fixed to the recording paper storage section, a lever fixing shaft L _G fixedly installed on the main body frame, and a locking part L _K that can be locked to the lever fixing shaft at the tip. and is disposed in the recording paper storage section in a loose manner with respect to the sprocket bearing S _G in order to position and fix the recording paper storage section in relation to the locking portion and the lever fixing shaft. A detachable lever L is provided, and the recording paper accommodating portion is engaged with the main body frame via the detachable lever.

<Example> Hereinafter, an example of the present invention will be described in detail based on the drawings. In the following drawings, parts that overlap with those in FIG. 3 are given the same numbers, and their explanations will be omitted.

FIG. 1 is a schematic sectional view of a recording paper storage section of a conventional recorder, and FIG. 2 is a supplementary explanatory diagram of FIG. 1.

In FIGS. 1 and 2, G represents a main body frame (partially shown in FIG. 1).
The recording paper storage section 20 is rotatably supported by a rotation center shaft 30 with respect to the main body frame G, and rotates about the rotation center shaft 30 as a fulcrum. One end of the rotation center shaft 30 is fixed to the main body frame G, and the other end is rotatably inserted into a hole provided in the side plate 21 of the recording paper storage section 20. C _B is a coil spring that presses the recording paper storage section 20 to the left in the figure (when it is on the left, it presses it to the right).
The frame _20F of the recording paper storage section 20 is screwed to the left and right side plates 21 by screws (not shown). A sprocket bearing S _G for receiving the sprocket shaft 1a, a spring fixing pin S _P to which one end of a spring S _B (to be described later) is engaged, and a rotation guide pin K _P are fixed to the side plate 21. L is a detachable lever (hereinafter referred to as "lever") for positioning and fixing the recording paper storage section 20. This lever L is loosely engaged with the sprocket bearing S _G , and the spring S B has one end fixed to the spring fixing pin S _P , and the other end of the spring S _B is assembled, and the entire lever is pulled clockwise. . L _G is a lever fixing shaft fixed to the main body frame G, and by locking the lever locking part L _K to this lever fixing shaft L _G ,
The recording paper storage section 20 is engaged with the main body frame G by the lever L. H is external sprocket 1
It is a gear that receives rotational force to rotate the
It is fixed to the sprocket shaft 1a with a push screw (not shown). G _D is a rubber damper that has a shape that allows the recording paper storage section 20 to rotate smoothly and can be attached or detached with a single touch. It is provided so as to be fitted into a long and narrow hole (guide hole) 20a. m is a notch in the main body frame G.

In such a configuration, the normal recording paper storage section 20
are the upper contact part of the locking part L _K of the lever L and the lever fixing shaft L _G , and the notch part m of the main body frame G.
and the contact part of the sprocket bearing S _G.

When replacing the recording paper, press the push part L _O of the lever L.
Push down to disengage the locking part L _K of the lever L from the lever fixing shaft L _G , and then remove the recording paper storage part 20.
Push down until it comes out in front. The recording paper 9 is now ready to be stored.

After storing the recording paper 9, lift the recording storage section 20, return it to the state shown in the figure, and press the locking part L _K of the lever L.
By engaging the lever fixed shaft _LG , the recording and storage operation is completed.

At this time, the material etc. of the rubber damper _GD should be determined by selecting a value such that the frictional force between the rubber damper _GD and the rotation guide pin _KP can be smoothly attached and detached from the record storage section 20. .

By the way, the structure of the engaging device including the lever L as shown in FIG. 2 may be provided at both ends of the recording paper storage section 20 or only on one side.
In short, it goes without saying that the design can be changed in consideration of strength, operability, etc.

<Effects of the invention> As mentioned above, the invention has been explained in detail along with the examples.According to the recorder of the invention,: The material of the rubber damper is appropriately selected to optimize the generated frictional force. , the recording paper storage section will not fall suddenly during storage work,
It can be operated smoothly.

:Since the lever is installed on the sprocket bearing,
The sprocket can be positioned reliably.

:The rubber damper can be attached and detached with one touch, so
Maintenance becomes easier.

: Since the structure is simple, production is easy, and the number of component parts is small, so the product can be provided at a low price.
