Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device used as an output device for electronic equipment such as personal computers (personal computers) and word processors (word processors).

[0002]

2. Description of the Related Art A recording device having functions such as a printer, a copying machine and a facsimile, or a recording device used as an output device of a compound machine or a workstation including a computer, a word processor, etc., is based on image information and is made of paper or a thin plastic plate. Recording material (recording medium) such as (OHP)
Is configured to record an image. These recording devices can be classified into an ink jet type, a wire dot type, a heat sensitive type, a thermal transfer type, a laser beam type and the like depending on the recording system of the recording means used. Also, from another side,
The printing apparatus is mainly used for a serial type printing apparatus that prints one line at a time and, when the printing of one line is completed, sequentially feeds one line at a time, and a page type printer that prints one page at a time. It can be different.

In recent years, many personal computers, word processors, and the like, which are the hosts of recording devices, are small, lightweight, inexpensive, and portable, such as notebook type and book type. Therefore, even as a recording device, among the recording systems roughly classified above,
A serial type recording apparatus that is small, lightweight, inexpensive, and in high demand is preferable.

In most cases, the recording apparatus is usually placed on a desk or the like for use. In that case, in order to prevent the recording apparatus from being displaced from the position where it is placed, the recording apparatus has an exterior surface. An elastic body such as rubber is attached. Further, in the ink jet type recording apparatus, since the recording material and the recording head are not in contact with each other, the recording accuracy is easily influenced by the outside of the apparatus. Therefore, the elastic body attached to the exterior surface not only serves to fix the device, but also has the function of removing vibrations from the outside. In order to obtain both effects, the optimal material and shape of the elastic body are used. Has already been proposed.

The number of elastic bodies used is usually four, but in many cases two functional bodies are sufficient. When there are two elastic bodies, it is common to provide two protrusions on the exterior surface at different positions and support them at four points. Further, in recent compact recording apparatuses, when recording on ordinary thin paper, the apparatus is placed horizontally, and when recording on thick paper or postcards, or when using an automatic paper feeder, the recording apparatus is 90 °. There is a form in which it is rotated and used upright, which improves usability and reduces the installation area. In such a case, two elastic bodies are used for each of the lower surface and the back surface, and a total of four elastic bodies are used.

[0006]

However, the above-mentioned conventional example has the following drawbacks. In the case of using four elastic bodies, two on each side different by 90 °, especially in the ink jet recording system, the materials of those elastic bodies,
This is because the elastic body is expensive due to the special shape, which leads to an increase in cost. In addition, increasing the number of elastic bodies also increases the number of manufacturing processes, and particularly when using a double-sided tape or adhesive, it takes time to handle one elastic body, which leads to an increase in manufacturing costs. is there.

Therefore, it is an object of the present invention to provide a recording apparatus capable of reducing the number of parts of an elastic body provided on the exterior without impairing the vibration isolation property.

[0008]

In order to achieve the above-mentioned object, the present invention is a recording apparatus in which an elastic body for vibration isolation is attached to a part of the exterior, and two parts of the elastic body are exterior. The recording device is characterized in that it forms a support surface by projecting from two different surfaces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described with reference to the drawings. 1 and 2 are perspective views showing a first embodiment of a recording apparatus of the present invention. FIG. 1 shows a state in which the recording apparatus is placed horizontally and the recording paper is manually fed, and FIG. 2 shows a state in which the recording apparatus is placed vertically and an automatic paper feeding device is attached. Both figures show the same recording apparatus. Is shown.

First, the structure of the recording apparatus will be schematically described. In FIG. 1 and FIG. 2, reference numeral 1 denotes the exterior of the recording apparatus, and 2 functions as a paper feed tray when the recording apparatus is used for manual paper feeding (in the case shown in FIG. 1), When using with the automatic paper feeder installed (Fig. 2
(In the case shown in (1)), it functions as a discharge tray, and when the recording apparatus is not used, it functions as a cover that closes the recording apparatus to protect the inside (hereinafter, referred to as a cover for convenience of description). Reference numeral 3 denotes a recording sheet which is a recording material, 4 denotes a discharge roller for discharging the recording sheet 3,
Reference numeral 5 denotes a key switch that is manually operated to perform various operations of the recording apparatus, 6 denotes a platen, 7 denotes an automatic sheet feeder, 8 denotes a recording head, and 9 denotes an exterior of the recording apparatus. The anti-vibration rubber (elastic body) attached to is shown.

Further, this recording apparatus is a serial type recording apparatus in which recording is performed line by line, and when recording of one line is completed, the recording paper is fed and another line is recorded. As a recording method, an ink jet method is used in which an electro-thermal conversion element is provided in a recording head and a pulse signal is applied to the electro-thermal conversion element to eject ink for recording.

Next, the operation of the recording apparatus will be described.
In the case of the manual paper feeding of FIG. 1, the recording paper 3 is set on the cover 2 and the key switch 5 is pressed to press the recording paper 3
Are transported by a transport roller (not shown). When the recording paper 3 is conveyed to the recordable area, the carriage equipped with the recording head 8 scans in the direction orthogonal to the conveying direction,
Ink is ejected from the recording head 8 in synchronization with the movement amount of the carriage, and recording is performed on the recording paper 3. When the recording for one line is completed, the recording paper 3 is conveyed to the next recording area, and the carriage scans again to perform recording. When the recording is sequentially performed line by line and the recording is performed on all the areas of the recording paper 3, the recording is completed.

When the automatic paper feeder of FIG. 2 is installed, a plurality of recording papers 3 are set in the automatic paper feeder 7 in advance. By operating the key switch 5, the recording papers 3 are conveyed one by one from the automatic paper feeder 7, and are conveyed to the recordable area as in the case of FIG. Subsequent operations are sequentially recorded line by line as in the case of the manual paper feed shown in FIG.

During the series of recording operations described above, drooling of recording due to vibration from a desk or the like on which the recording device is placed is suppressed,
Further, a vibration proof rubber 9 is attached so that the recording apparatus is placed on a desk so as not to slip.

FIG. 3 (b) shows a state in which the anti-vibration rubber 9 is attached to the outer case 1, and FIG. 3 (a) shows the pre-deformation shape of the anti-vibration rubber 9 before attachment. The vibration proof rubber 9 is made of urethane rubber, and is selected as a material exhibiting excellent characteristics among various rubber materials by evaluating the damping characteristic of disturbance and the friction coefficient of the surface.

As shown in FIG. 3 (a), the shape is such that two cylindrical portions are provided on a thin plate, and a double-sided tape 10 for attaching to the exterior is attached to the back surface thereof. . For attachment to the outer casing, the folded portion is bent between the two cylindrical portions so that the cylindrical portion is opened, and is attached to the outer casing 1 (FIG. 3B).

As can be seen from FIG. 3B, since the anti-vibration rubber projects in two directions, the damping characteristics and the frictional force with the desk both when the recording apparatus is placed horizontally and vertically. In both cases, the same effect as when the anti-vibration rubber is attached to the lower surface and the back surface is obtained. Regarding the cost, the number of rubber vibration proof rubber used to be four in the past, but now it is two, but the material cost per one increases, but the cost for parts management, assembly, etc. is considerably reduced, so the cost is low as a whole.
In particular, since the anti-vibration rubber 9 is a molded product, the number of the anti-vibration rubber 9 is reduced even if the shape is slightly increased, which leads to a significant cost reduction.

Next, a second embodiment will be described with reference to FIG. In the embodiment of FIG. 4, the main body of the recording apparatus, that is, the carriage, the recording head, the exterior of the recording paper, etc. are all the same as those of the first embodiment, and only the shape of the vibration-proof rubber is different. The anti-vibration rubber 11 is a molded product using urethane rubber as a material similarly to the first embodiment. As shown in FIG. 4 (a), the shape is a hollow triangular prism, and the recesses 1 for attaching to the exterior 1 are provided on both sides.
1B is formed, and a hole 11A is formed in the center. As shown in FIG. 4B, the outer casing 1 is attached by fixing the recess 11B by inserting it into a hole provided in the outer casing 1 in advance.

With such a structure, the anti-vibration rubber 11 can be used without being separated from the outer package 1 without using the double-sided tape 10 used in the first embodiment. As for the damping effect of the disturbance, the thickness of the anti-vibration rubber is thick and the presence of the hole 11A significantly improves the damping characteristic as compared with the first embodiment. Therefore, if the damping characteristic is the same as that of the first embodiment, the material can be changed to rubber that is cheaper than urethane rubber. Further, as in the first embodiment, it is clear from the figure that it is effective against disturbances from two directions.

[0020]

As described above, according to the present invention,
An elastic body is attached to a part of the exterior, and at least 2 of the exterior
Since any one surface of one elastic body is exposed at the same time from two different surfaces, it is possible to reduce the cost without lowering the vibration isolation performance as compared with a recording device in which a conventional elastic body is provided on each of the two surfaces. Is possible.
