雑で′かつ高価となる欠点があった。As shown in Fig. 1, conventional copying machines have many paper detectors d installed above the paper 6 transport path and near the paper feed tray C. When a paper jam occurs, the presence or absence of paper a on paper feed tray C is detected and checked. Further, as a detector d for the paper α, for example, as shown in FIG. When the reflected light from paper a is guided to the light receiving element i again using the light receiving element i, the signal charged and converted by the light receiving element i is transferred to the amplifier circuit j% and the control circuit k. There is known a tortoise which is configured to output the information to a display m through a drive circuit t and to display the presence or absence of one sheet a with one display. However, since the paper detection and display device uses many electronic circuits, it has the disadvantage that the circuits are complex and expensive.

になっている。An embodiment of the present invention will be described in detail below with reference to the drawings shown in FIG. As in the past, several Kg units are installed near the paper transport path and paper feed tray of the machine, and are configured as follows. In other words, the above paper detection! There are three bundles of light 7 Aiper 3 inside +, and -,? :C, 1 out of 3 lights 7 eyelids 3-
At one end, a light emitting part of a light emitting element 5 driven by a light emitting element driving circuit 4 is provided to face each other, and at one end of another light emitting element 3, a light receiving element 6 is provided to face each other. Furthermore, one end of the remaining one 3C is extended to the display section 2 provided on the display panel of the main body of the copying machine, respectively.
The paper detector installation location display 2α displayed on the display unit 2 is arranged at the corresponding part, and the presence or absence of the paper 7 is optically indicated by blinking.Meanwhile, each of the above-mentioned optical fibers The other ends of 3g, 3b, and 3c are installed at a position facing the paper 7 moving on the paper transport path or at a position facing the paper 7 housed in the paper feed tray, and are connected via the optical fiber 3-. The light from the light emitting element 5 that is guided onto the paper 7 and reflected on the paper 7 is made to enter through the fIAS of the other optical fibers 3b and 3C. The reflected light incident on the optical fan bar 3b reaches the light receiving element 6, is converted into an electrical signal by photoelectric conversion, is further amplified by the amplifier 8, and is then input to the control circuit 9.

りこれを表示するようになっている。The control circuit 9 controls the main motor of the main body of the copying machine, and therefore operates to stop the main motor when the paper detector 1 detects, for example, a paper jam. Also, optical fiber 3. The light entering c is guided to various locations on the paper detector installation location display 2G on the display section 2, and if there is paper 7 at the paper detector 1 installation position, the light will turn on □, and if there is no paper, the light will turn off. This is now displayed.

Of course, it is also possible to use three or more. Further, as shown in FIG. 4, if the light emitting element 5 and the light receiving element 6 are installed near the paper 7, the light emitting element 5 can guide the light to the paper 7 and receive the light reflected from the paper 7.

化と価格の。3C can be omitted. Further, in the above embodiment, the reflected light from the paper 7 is used, but the light emitting element 5, the light receiving element 6, and the optical fiber 6 are arranged to face each other across the paper conveyance path,
The presence or absence of the paper 7 may be detected using light shielding by the paper 7. As described in detail above, this invention allows optical fibers to detect the presence or absence of paper to the display section. Since the sensor is guided and displayed optically, there is no need for complex electronic circuits like in conventional photoelectric conversion detectors, making the device itself smaller and cheaper.
