際にはカバーを取外す必要がある。In devices with built-in printers, such as word processors, the printer cover must be opened and closed to feed and eject paper when the printer is operating, and the cover must also be removed when replacing the ribbon or disposing of paper jams. .
従来、この種のカバー１のヒンジ構造は、第２図に示す
ように、外装ケース２に設けられ紙面に直角に突出した
凸部３と、これにカバーの凹部４がゆるく嵌合し回動自
在に保持されるものが知られていた。Conventionally, as shown in FIG. 2, the hinge structure of this type of cover 1 is such that a convex portion 3 provided on an exterior case 2 and protruding at right angles to the plane of the paper and a concave portion 4 of the cover loosely fit into the convex portion 3 and rotate. It was known that it could be held freely.
ここで凸部３は、円筒形状部の一部が切欠かれた形状を

いた。[Problem to be solved by the invention] However, in the conventional technique shown in FIG.
Since the amount of engagement 1e between the concave part 4 and the convex part of the outer case 2 is small, when the cover 1 is opened and closed, the lf part near the connection part between the lc and the cylindrical hole 1a is worn out, and the concave part of the cover 1 is initially There was a problem in that the mounting part 1g could no longer be held in the position shown in FIG. In addition, due to variations in the finished dimensions of the interval 1d between the linear grooves of the recess 4 of the cover 1 and the diameter 2d of the outer case, the engagement amount 1e
This has become a problem as there are cases where it is almost impossible to secure the required amount.
本考案の目的は上記問題点を解決し、カバーの上方への
外れが確実に防止できるプリンタ装置のカバー取付構造
を提供することにある。An object of the present invention is to solve the above-mentioned problems and provide a cover mounting structure for a printer device that can reliably prevent the cover from coming off upward.
［課題を解決するための手段］
本考案が上記目的を達成するために採用した第１の手段
は、
（１）外装ケースに設けられ、円筒状の一部が外装ケー
ス上面に対して傾斜した直線状に切欠かれ、て支軸を構
成する凸部と、カバーに設けられ、上記凸部に回動自在
に嵌合される円筒形状の穴部と上記穴部に連なり上記凸
部からカバーを着脱するための直線状の溝部とからなり
、上記直線状の溝部がケース上面に対して一定の角度を
もって形成されている凹部とからなっており、また、別
の手段は、
（２）外装ケースに設けられ、円筒状の一部が外装ケー
ス上面に対して傾斜した平行線状に切欠かれて支軸を構

に嵌合される円筒形状の穴部と上記穴部に連なり上記凸
部からカバーを着脱するための直線状の溝部より形成さ
れている凹部とからなっている。[Means for Solving the Problems] The first means adopted by the present invention to achieve the above object is as follows: (1) A cylindrical part is provided in the outer case, and a part of the cylindrical part is inclined with respect to the upper surface of the outer case. A convex portion that is notched in a straight line and constitutes a support shaft, a cylindrical hole provided in the cover and rotatably fitted into the convex portion, and a hole that connects to the hole and allows the cover to be removed from the convex portion. (2) Exterior case A convex part is provided on the cover, and a cylindrical part is notched in a parallel line shape inclined with respect to the upper surface of the outer case to constitute a support shaft, and a convex part is provided on the cover and is rotatably fitted into the convex part. The cover is made up of a cylindrical hole and a recess that is connected to the hole and is formed by a linear groove for attaching and removing the cover from the convex portion.
１作用］
第１の本考案によれば、カバーに設けられたカバーを着
脱するための直線状の溝部がケース上面に対して一定の
角度をもって形成されているため、カバーを閉じた際に
、その円筒形状の穴部は直線状の溝部が傾斜して設けら
れた分だけ外装ケースの凸部の下端面に深く接触する。1 Effect] According to the first invention, since the linear groove provided in the cover for attaching and detaching the cover is formed at a certain angle with respect to the upper surface of the case, when the cover is closed, The cylindrical hole is in deep contact with the lower end surface of the convex portion of the outer case by an amount corresponding to the slope of the linear groove.
すなわち、円筒形状の穴部と凸部との係合量が大きくな
るので上方への外れがなくなる。That is, since the amount of engagement between the cylindrical hole and the convex portion is increased, there is no possibility of upward dislodgement.
また、第２の本考案によれば、外装ケースの凸部が外装
ケース上面に対して傾斜した平行線状に切欠かれて支軸
を構成しているため、カバーに設けられ、凹部の一部を
形成しているカバーを着脱するための直線状の溝部は、
その間隔を上記平行線状の間隔（厳密にはこれに若干余
裕をもたせて）とすれば足りることになる。したがって
、これによっても円筒形状の穴部と凸部との係合量が大
きくなる。Further, according to the second invention, since the convex part of the outer case is notched in a parallel line shape inclined to the upper surface of the outer case and constitutes a support shaft, the convex part of the outer case is provided in the cover and a part of the concave part is formed. The linear groove for attaching and detaching the cover that forms the
It is sufficient if the interval is the above-mentioned parallel line interval (strictly speaking, with a slight margin in this interval). Therefore, this also increases the amount of engagement between the cylindrical hole and the convex portion.

The figure is a sectional view showing a first embodiment of the present invention. In the figure, a recess 4 is provided in a cover 1 made of plastic or the like, and is formed from a linear groove IJ whose cross section is shown by straight portions lc and 1b, and a cylindrical hole 1a whose cross section is circular.
Like the cover 1, an exterior case 2 made of plastic or the like is provided with a convex portion 3, the cross section of which is an arcuate portion 2a.
and a straight portion 2b. The distance 1d between the straight portions 1b and 1c of the linear groove IJ is larger than the distance 2c between the straight portion 2b of the convex portion 3 and a straight line parallel to the straight portion 2b and in contact with the circular arc portion 2a. Allows for insertion and removal. Furthermore, this interval 1d is formed smaller than the diameter 2e of the convex portion 3.
第１図はカバー１の凹部４と外装ケース２の凸部３とが

凸部との係合量１ｅは、第２図の従来例に示す係合量１
ｅより大きく、カバー１の開閉による凹部４の摩耗や、
凹部４と凸部３の仕上り寸法のばらつきを考慮しても、
カバー１の取付部１ｇが上方に外れることはない。FIG. 1 shows a state in which the concave portion 4 of the cover 1 and the convex portion 3 of the exterior case 2 are fitted, and the cover 1 is covered by the exterior case 2. At this time, as is clear from the drawing, the cover 1
The linear portions 1c and 1d of the recess 1a have an angle 1h with respect to the vertical direction, and the amount of engagement 1e between the recess 4 of the cover 1 and the protrusion of the exterior case 2 is as shown in the conventional example in FIG. Engagement amount 1
e, wear of the recess 4 due to opening and closing of the cover 1,
Even considering the variation in the finished dimensions of the concave portion 4 and the convex portion 3,
The mounting portion 1g of the cover 1 will not come off upward.
第４図は本考案の第２実施例を示す断面である。第２図
に示す従来例との相違は、外装ケース２に形成された凸
部３の直線部２ｂを平行にもう一箇所段けた点にある。FIG. 4 is a cross-sectional view showing a second embodiment of the present invention. The difference from the conventional example shown in FIG. 2 is that the linear portion 2b of the convex portion 3 formed on the outer case 2 is stepped in parallel to another point.
したがって、凸部３の直線部２ｂ、２ｂの間隔２ｃは一
方の直線部を欠〈従来例の凸部に比べて当然なから小さ
くなる。そこで、カバー１の直線状溝部ＩＪを形成する
直線部１ｂ、１ｃの間隔１ｄは従来例に比べて狭く形成
できるので、係合量１ｅは反対に大きくとれる。Therefore, the interval 2c between the linear portions 2b, 2b of the convex portion 3 is smaller than that of the conventional convex portion, since one of the straight portions is omitted. Therefore, since the interval 1d between the linear parts 1b and 1c forming the linear groove part IJ of the cover 1 can be formed narrower than in the conventional example, the engagement amount 1e can be made larger.
したがって、カバー１の上方への外れを有効に防止でき
る。Therefore, the cover 1 can be effectively prevented from coming off upward.
第５図は本考案の第３実施例を示す断面図である。これ
は第４図の実施例とは外装カバー１の直線状溝部ＩＪを
第１図の実施例と同様に傾斜して設けた点で相違する。FIG. 5 is a sectional view showing a third embodiment of the present invention. This differs from the embodiment shown in FIG. 4 in that the linear groove IJ of the exterior cover 1 is provided at an angle similar to the embodiment shown in FIG.
したがって、係合量１ｅが第１図、第３図の各実施例に
比べて大きくなることは改めて説明することもない。当
然、カバー１の上方への外れがより確実に防止できる効
果を有する。Therefore, there is no need to explain again that the engagement amount 1e is larger than in each of the embodiments shown in FIGS. 1 and 3. Naturally, this has the effect of more reliably preventing the cover 1 from coming off upward.
