BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a facsimile apparatus whose operation portion can be rotated facing an operator, and which displays letters, numbers, symbols and the like by rotating them in accordance with the rotation of the operation portion. 
     2. Description of the Related Art 
     Heretofore, a facsimile apparatus is so designed that the horizontal direction it faces will be fixed. That is, its front side is supposed to face a user. Accordingly, the operation portion which includes numerical keys for inputting a phone number, start and stop keys, and a function selection key, is fixed to the apparatus, which obliges the user to stand facing the front side of the apparatus so that he can easily read the names of the keys. In this case, the user cannot make the apparatus face the arbitrary direction so that it will fit in the place where he wants to situate it, and hence the choice of where to situate it is restricted. This is inconvenient. Therefore, a facsimile apparatus whose operation portion can be horizontally rotated so that it can be used whichever direction it faces, is proposed. 
     For example, there is an electrophotography apparatus disclosed in Unexamined Japanese Patent Publication No. 6-124008. In the apparatus, its operation portion with numerical keys and a liquid crystal display can be rotated. Even if a user situates the apparatus with its front side aside, he can read the names of the keys and the display image regularly right to left. 
     In this case, however, the constitution will be complicated because the rotating operation portion includes a liquid crystal display as well as numerical keys and hence the number of rotating contact points transmitting signals increases. Furthermore, considering that more and more facsimile apparatuses are miniaturized now, it is difficult to enlarge the operational member, and hence both the numerical keys and the liquid crystal display are obliged to be small. This may cause the keys to be hard to press and the display image to be hard to read. 
     The present invention is made in view of the above-described subject and it is the object of the present invention to provide a facsimile apparatus whose operation portion and display are both conspicuous and which can be easily operated, regardless of which side a user stands on. 
     SUMMARY OF THE INVENTION 
     In order to achieve the above-described object, the present invention provides a facsimile apparatus comprising an operation member which is arranged horizontally and can be rotated, and a display member which is arranged at the same level as the operation member and rotates a display image in accordance with the rotation of the operation member. 
     Due to the above configuration, the apparatus is easier to operate because its operation panel and display member both face the operator regardless of which side he stands on.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     A facsimile apparatus according to a preferred embodiment of the present invention will now be described in detail, with reference to the drawings. 
     FIG. 1 is a top view of a facsimile apparatus according to a preferred embodiment of the present invention, in case of situating it with its rotating operation portion which will be described later rightward, and FIG. 2 is a perspective view of the facsimile apparatus shown in FIG. 1. 
     In FIGS. 1 and 2, the facsimile apparatus has an insertion slot 1 on one side, into which to insert an original transmitted, and also has an ejection slot 2 on the opposite side, which is parallel to the insertion slot 1 and out of which printed paper is ejected. Besides, the facsimile apparatus has a rotating operation portion 3 in the right part in FIG. 1 of the panel between the insertion slot 1 and the ejection slot 2. The rotating operation portion 3 can be rotated as shown by the arrow in FIG. 1, by a user&#39;s finger or the like, and is settled in any position of every 90 degrees (0, 90, 180 or 270 degrees). Furthermore, the facsimile apparatus has a liquid crystal display 4 hereinafter referred to as LCD 4 in the left part in FIG. 1 of the panel between the insertion slot 1 and the ejection slot 2. The LCD 4 displays a phone number inputted, or a function selected, by the rotating operation portion 3. The rotating operation portion 3 has numerical keys 6 (0 to 9, * and #) for inputting a phone number, and also has function selection keys 7 (A, B and C) for selecting a certain function: for instance, memorizing phone numbers, pausing or the like. And besides, the facsimile apparatus has a stop key 8 which interrupts transmission, erases inputted data or the like, and also has a start key 9 which starts transmission. 
     FIG. 3 is a sectional view showing the constitution of the rotating operation portion 3 in FIG. 1. In FIG. 3, the rotating operation portion 3 is swiveled to an outer casing 14, and has a hollow rotor 15 whose vertical section is rectangular. On the hollow rotor 15 are numerical keys 6, function selection keys 7, a stop key 8 and a start key 9, whose contact points are on a circuit substrate 16. The hollow rotor 15 is retained by a retaining member 17 so that it can be rotated, and between the retaining member 17 and the circuit substrate 16 is a rotating contact point 18. The retaining member 17 is on a circuit substrate 19 such as a mother board, and a wiring pattern which is not shown in the figure and the rotating contact point 18 are connected to it. 
     In addition, on the retaining member 17 is a detection member as shown later in FIG. 4 for detecting the position of the rotating operation portion 3, that is, detecting in which position of every 90 degrees (0, 90, 180 or 270 degrees) it is settled. 
     FIG. 4 is a block diagram showing the electrical constitution for changing the display image. In FIG. 4, the present embodiment has a detection member 25 for detecting the position of every 90 degrees of the rotating operation portion 3, and also has an LCD driver 26, which stores the data inputted for displaying letters on the LCD 4, generates data for displaying the letters by rotating them (by 0, 90, 180 or 270 degrees) on an X-Y matrix according to a detection of every 90 degrees by the detection circuit 25, and then transmits the data to the LCD 4. 
     The detection circuit 25 is composed of a rotor 30 which rotates in accordance with the rotation of every 90 degrees of the hollow rotor 15, and switches SW1, SW2, SW3 and SW4 which touch the projection of the rotor 30 alternately, every 90 degrees (0, 90, 180 or 270 degrees), and whose ON-state signals the LCD driver 26 takes in. 
     The switches SW1 through SW4 may be mechanical ones which is turned on by touching the projection of the rotor 30, or optical ones which is turned on by the projection of the rotor 30 interrupting beams. Or they may be magnetic ones or the like. 
     Next, the motion and function of the present embodiment will be explained. 
     In FIGS. 1 through 4, when transmitting, a user puts an original on the insertion slot 1, and transmits it by operating the numerical keys 7 and the start key 9 on the operation portion 3. The contents according to the operation of the keys on the operation portion 3, is displayed in the LCD 4. And when receiving, the apparatus works like conventional facsimile apparatuses, ejecting printed paper out of the ejection slot 2. 
     In such a motion, the horizontal direction the apparatus faces will be changed so that the apparatus will fit in the place where it is situated. In case of the direction of the apparatus shown in FIG. 1 suppose it to be 0 degree, the ejection slot 2 faces a user. In this case, the user will rotate the rotating operation portion 3 every 90 degrees, and settle it so that he can easily read the letters and the like on the keys (&#34;0&#34; to &#34;9&#34;, &#34;*&#34; and &#34;#&#34; on the numerical keys 6; &#34;A&#34;, &#34;B&#34; and &#34;C&#34; on the function selection keys 7; &#34;STOP&#34; on the stop key 8; &#34;START&#34; on the start key 9). 
     In accordance with the rotation of the rotating operation portion 3, the rotor 30 of the detection circuit shown in FIG. 4 will rotate, and the projection of the rotor 30 will touch the switch SW1 and turn it on. The ON-state signal will be taken in by the LCD driver 26. The LCD driver 26 will rotate the image of inputted letters when displaying it on an X-Y dot matrix ,in this case, in the normal position of 0 degree, transmit the display data to the LCD 4 shown in FIG. 1, and display the letters. 
     In FIG. 1, letters &#34;START&#34; are displayed on the LCD 4 so that their running direction will enable the user facing the insertion slot 2 to easily read or recognize them. In this case, the LCD 4 may display the image at any arbitrary angle in accordance with the rotation of the rotating operation portion 3, but it is recommended that the display image should be rotated by 90 degrees when the rotating operation portion 3 rotates by 45 degrees, so that the display control will not be complicated. Thus, the image is displayed in any of the four directions, and will be rotated by 90 degrees when the rotating operation portion 3 rotates by ±45 degrees or more. And then the apparatus will be easily controlled and easy to handle. 
     FIG. 5 is a top view of the apparatus in case of situating it with its rotating operation portion 3 forward. In FIG. 5, the insertion slot 1 is on the right side, and the ejection slot 2 is on the left side, of the apparatus in a user&#39;s eyes. In this case, the user will rotate the rotating operation portion 3 by 90 degrees from the position shown in FIG. 1, and settle it so that he can easily read the names of the keys. 
     In accordance with the rotation of the rotating operation portion 3, the rotor 30 of the detection circuit 25 shown in FIG. 4 will rotate by 90 degrees, and the projection of the rotor 30 will touch the switch SW2 and turn it on. The ON-state signal will be taken in by the LCD driver 26. The LCD driver 26 will rotate the image of inputted letters when displaying it on an X-Y dot matrix (in this case, in the position of 90 degrees), transmit the display data to the LCD 4 shown in FIG. 1, and display the letters on the dot matrix. As a result, as shown in FIG. 5, the letters &#34;START&#34; on the LCD 4 are displayed so that their running direction will enable the user facing the rotating operation portion 3 to easily read them, that is, are displayed by rotating them by 90 degrees from the position shown in FIG. 1. 
     FIG. 6 is a top view of the apparatus in case of situating it with its rotating operation portion 3 leftward. In FIG. 6, the insertion slot 1 is the nearest to a user. In this case, the user will rotate the rotating operation portion 3 by 180 degrees from the position shown in FIG. 1, and the projection of the rotor 30 will touch the switch SW3. As a result, the names of the keys on the rotating operation portion 3 can be easily read, and the letters on the LCD 4 will be displayed by rotating them by 180 degrees from the position shown in FIG. 1, so that the user facing insertion slot 1 can easily read them. 
     FIG. 7 is a top view of the apparatus in case of situating it with its rotating operation portion 3 backward. In FIG. 7, the LCD 4 is the nearest to a user. In this case, the user will rotate the rotating operation portion 3 by 270 degrees from the position shown in FIG. 1, and the projection of the rotor 30 will touch the switch SW4. As a result, the names of the keys on the rotating operation portion 3 can be easily read, and the letters on the LCD 4 will be displayed by rotating them by 270 degrees from the position shown in FIG. 1, so that the user standing in the lower part of the figure can easily read them. 
     In the present embodiment, the apparatus rotates letters on the LCD 4 in accordance with the rotation of the rotating operation portion 3. In other words, the apparatus rotates the letters electrically and displays the image of them. Alternatively, the LCD 4 itself may be rotated mechanically. In this case, it is suggested that the LCD 4 itself should be rotated mechanically by transferring the rotation of the rotating operation portion 3 through a belt, gears or the like. 
     As is apparent through the above explanation, the present invention provides a facsimile apparatus whose operation portion and display are both conspicuous and which can be easily operated, regardless of which side an operator stands on. 
     In the concrete, the apparatus is easier to operate because its operation panel and display both face the operator regardless of which side he stands on. In addition, the image is displayed in any of the four directions and will be rotated by 90 degrees when the rotating operation portion 3 rotates by ±45 degrees or more, and hence the apparatus will be easily controlled and easy to handle. Furthermore, since its operation portion can be easily rotated by the operator standing on a side of the apparatus, the apparatus is even easier to handle. And furthermore, since its insertion slot and ejection slot are arranged symmetrically centering the operation panel, the apparatus is still easier to operate.
